Exploring the therapeutic implications of natural compounds modulating apoptosis in vascular dementia

Vascular dementia (VaD) is a prevalent form of dementia stemming from cerebrovascular disease, manifesting in memory impairment and executive dysfunction, thereby imposing a substantial societal burden. Unfortunately, no drugs have been approved for the treatment of VaD due to its intricate pathogenesis, and the development of innovative and efficacious medications is urgently needed. Apoptosis, a programmed cell death process crucial for eliminating damaged or unwanted cells within an organism, assumes pivotal roles in embryonic development and tissue homeostasis maintenance. An increasing body of evidence indicates that apoptosis may significantly influence the onset and progression of VaD, and numerous natural compounds have demonstrated significant therapeutic potential. Here, we discuss the molecular mechanisms underlying apoptosis and its correlation with VaD. We also provide a crucial reference for developing innovative pharmaceuticals by systematically reviewing the latest research progress concerning the neuroprotective effects of natural compounds on VaD by regulating apoptosis. Further high-quality clinical studies are imperative to firmly ascertain these natural compounds' clinical efficacy and safety profiles in the treatment of VaD.

Predicting structure-targeted food bioactive compounds for middle-aged and elderly Asians with myocardial infarction: insights from genetic variations and bioinformatics-integrated deep learning analysis

Myocardial infarction (MI) is a significant global health issue. Despite the advances in genome-wide association studies, a complete genetic and molecular understanding of MI is elusive and needs to be fully explored. This study aimed to elucidate the genetic framework of MI and explore the potential health benefits of natural compounds (NCs). The genetic architecture of MI was explored using data from the Korean Genome and Epidemiology Study. We pinpointed crucial protein-coding genes related to MI by multi-marker analysis of genomic annotation for gene-based analysis. The bioinformatics-integrated deep neural analysis of NCs (BioDeepNat), a novel disease discovery application, was utilized to assess the influence of NCs on MI-related target proteins and validated with molecular docking analysis. The BioDeepNat application revealed significant NCs on MI-related target proteins, such as E-resveratrol, epicatechin 3-gallate, and kaempferol. The E3 region of RNF213 protein with a point mutation (Arg4810Lys) had different binding energies with NCs, such as ursolic acid and olean-12-en-28-oic acid, compared to the wild type. However, ginsenosides, eleutheroside, oleanolic acid, and hederagenin showed similar binding energies to wild and mutated types of RNF213 protein. The predicted NCs were primarily sourced from foods such as common grapes and teas. Aromatic hydrocarbons are frequently observed as the prevalent functional groups with high binding affinity for NCs in a molecular docking analysis. In conclusion, the proteins encoded by these genes identified by gene-based analysis interacted with several NCs with health promotion found in day-to-day foods, particularly E-resveratrol and kaempferol. This understanding offers promising directions for precision nutrition strategies in MI.

Dietary plants for oral cancer prevention and therapy: A review of preclinical and clinical studies

Oral cancer is a disease with high mortality and rising incidence worldwide. Although fragmentary literature on the anti-oral cancer effects of plant products has been published, a comprehensive analysis is lacking. In this work, a critical and comprehensive evaluation of oral cancer preventative or therapeutic effects of dietary plants was conducted. An exhaustive analysis of available data supports that numerous dietary plants exert anticancer effects, including suppression of cell proliferation, viability, autophagy, angiogenesis, invasion, and metastasis while promoting cell cycle arrest and apoptosis. Plant extracts and products target several cellular mechanisms, such as the reversal of epithelial-to-mesenchymal transition and the promotion of oxidative stress and mitochondrial membrane dysfunction by modulation of various signaling pathways. These agents were also found to regulate cellular growth signaling pathways by action on extracellular signal-regulated kinase and mitogen-activated protein kinase, inflammation via modulation of cyclooxygenase (COX)-1, COX-2, and nuclear factor-κB p65, and metastasis through influence of cadherins and matrix metalloproteinases. In vivo studies support these findings and demonstrate a decrease in tumor burden, incidence, and hyperplastic and dysplastic changes. Clinical studies also showed decreased oral cancer risk. However, high-quality studies should be conducted to establish the clinical efficacy of these plants. Overall, our study supports the use of dietary plants, especially garlic, green tea, longan, peppermint, purple carrot, saffron, tomato, and turmeric, for oral cancer prevention and intervention. However, further research is required before clinical application of this strategy.

miRNA, phytometabolites and disease: Connecting the dots

miRNAs are tiny noncoding ribonucleotides that function as critical regulators of gene-expression in eukaryotes. A single miRNA may be involved in the regulation of several target mRNAs forming complex cellular networks to regulate diverse aspects of development in an organism. The deregulation of miRNAs has been associated with several human diseases. Therefore, miRNA-based therapeutics is gaining interest in the pharmaceutical industry as the next-generation drugs for the cure of many diseases. Medicinal plants have also been used for the treatment of several human diseases and their curative potential is attributed to their reserve in bioactive metabolites. A role for miRNAs as regulators of the phytometabolic pathways in plants has emerged in the recent past. Experimental studies have also indicated the potential of plant encoded secondary phytometabolites to act as cross-regulators of mammalian miRNAs and transcripts to regulate human diseases (like cancer). The evidence for this cross-kingdom gene regulation through miRNA has gathered considerable enthusiasm in the scientific field, even though there are on-going debates regarding the reproducibility and the effectiveness of these findings. In this review, we provide information to connect the medicinal and gene regulatory properties of secondary phytometabolites, their regulation by miRNAs in plants and their effects on human miRNAs for regulating downstream metabolic or pathological processes. While further extensive research initiatives and good clinical evidence are required to prove or disapprove these findings, understanding of these regulations will have important implications in the potential use of synthetic or artificial miRNAs as effective alternatives for providing health benefits.

Natural hypoglycaemic bioactives: Newer avenues and newer possibilities

The incidences of endocrine and metabolic disorders like diabetes have increased worldwide. Several proposed molecular pathways mechanisms for the management of diabetes have been identified, but glycaemic control is still a challenging task in the drug discovery process. Most of the drug discovery processes lead to numerous scaffolds that are prominent in natural products. The review deals with the natural bioactives as an α-amylase inhibitors, α-glucosidase inhibitors, protein tyrosine phosphatase-1B inhibitors, dipeptidyl peptidase-IV inhibitors, G-protein coupled receptors-40 agonists, PPAR-γ agonists and the activators of 5'-adenosine monophosphate-activated protein kinase and glucokinase. So, in this review, we focused on the hypoglycaemic bioactives, which will assist scientific developers, traditional medicinal practitioners, and readers to discover some potent antidiabetic molecules. Strategies like chemometric approaches, scaffold hopping, and total synthesis of natural products by group modification or ring opening/closing mechanism could be useful for the development of novel hit/lead antidiabetic molecules. The study concludes that each phyto molecule inherits a potential to get explored by repurposing techniques for various antidiabetic targets and offer an alternative antidiabetic therapeutic medicinal potential.

Hesperidin reduces systolic blood pressure in diabetic patients and has no effect on blood pressure in healthy individuals: A systematic review and meta-analysis

In recent years, there have been a number of studies where hesperidin was administered to modify arterial blood pressure, but the conclusions of each study are contradictory. In order to investigate the effect of hesperidin on blood pressure, we searched the CNKI, Wanfang Database, the VIP database, Sinomed database, Pubmed, Embase and The Cochrane Library databases, and searched the literature on hesperidin and blood pressure published in Chinese and English journals, mainly focusing on patients' systolic blood pressure and diastolic blood pressure. The search time frame was from the inception of the databases until December 2023. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the overall quality and used Cohen's kappa coefficient (κ) to measure agreement. We did preliminary screening of the retrieved literature through Notexpress, 14 articles with a total of 656 patients were included. Cochrance data conversion tool was used for data conversion, and RevMan 5.3 was used for meta-analysis, and finally Stata was used to make the Egger's test for the included study. The results of total population blood pressure showed that hesperidin had no antihypertensive effect on the population, but the conclusions changed when the population was divided into groups. The results of different populations showed that hesperidin had no effect on systolic blood pressure (weighted mean difference [WMD] = -0.50, 95% CI: -3.25 ~ 2.26, Z = 0.35, p = 0.72) and diastolic blood pressure (WMD = -0.51, 95% CI: -2.53 ~ 1.51, Z = 0.50, p = 0.62) in healthy individuals. However, hesperidin reduced systolic blood pressure in patients with type 2 diabetes (WMD = -4.32, 95% CI: - 7.77 ~ - 0.87, Z = 2.45, p = 0.01), and had a tendency to reduce diastolic blood pressure in diabetic patients (WMD = -3.72, 95% CI: -7.63 ~ 0.18, Z = 1.87, p = 0.06). The results in patients with type 2 diabetes needed to be further supported by future research focusing on individuals with diabetes.

Effect of grape-derived products on the serum levels of enzymes mainly produced by the liver: A systematic review and meta-analysis of parallel randomized controlled trials

In recent years, an increase in the incidence of liver diseases has been reported all over the world. This study aims to comprehensively summarize and quantitatively analyze the existing evidence concerning the effectiveness of grape-derived products on liver enzymes through a systematic review and meta-analytic approach. PubMed, Scopus, Cochrane Library, and ISI Web of Science were comprehensively searched until January 2024. Articles that reported the effect of grape-derived products on serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) levels were included. Weighted mean differences (WMDs) were pooled using a random-effects model. Nine studies were included in the meta-analysis. The results revealed that grape-derived products did not significantly change the concentrations of ALT (WMD: -2.70 IU/L, 95% CI: -6.14 to 0.75, p = 0.12), and AST (WMD: -1.42 IU/L, 95% CI: -3.54 to 0.70, p = 0.18). However, a significant reduction was observed in serum ALP levels (WMD: -5.49 IU/L, 95% CI: -9.57 to -1.4, p = 0.008). The present findings suggest that grape-derived products positively influence serum ALP levels among adults. However, a more comprehensive decision necessitates additional studies.

Current advances in the pain treatment and mechanisms of Traditional Chinese Medicine

Traditional Chinese Medicine (TCM), as a unique medical model in China, has been shown to be effective in the treatment of many diseases. It has been proven that TCM can increase the pain threshold, increase the level of endorphins and enkephalins in the body, and reduce the body's response to adverse stimuli. In recent years, TCM scholars have made valuable explorations in the field of pain treatment, using methods such as internal and external application of TCM and acupuncture to carry out research on pain treatment and have achieved more satisfactory results. TCM treats pain in a variety of ways, and with the discovery of a variety of potential bioactive substances for pain treatment. With the new progress in the research of other TCM treatment methods for pain, TCM will have greater potential in the clinical application of pain.

Neuroprotective and anti-inflammatory effects of curcumin in Alzheimer's disease: Targeting neuroinflammation strategies

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the accumulation of amyloid-beta plaques and neurofibrillary tangles, leading to neuronal loss. Curcumin, a polyphenolic compound derived from Curcuma longa, has shown potential neuroprotective effects due to its anti-inflammatory and antioxidant properties. This review aims to synthesize current preclinical data on the anti-neuroinflammatory mechanisms of curcumin in the context of AD, addressing its pharmacokinetics, bioavailability, and potential as a therapeutic adjunct. An exhaustive literature search was conducted, focusing on recent studies within the last 10 years related to curcumin's impact on neuroinflammation and its neuroprotective role in AD. The review methodology included sourcing articles from specialized databases using specific medical subject headings terms to ensure precision and relevance. Curcumin demonstrates significant neuroprotective properties by modulating neuroinflammatory pathways, scavenging reactive oxygen species, and inhibiting the production of pro-inflammatory cytokines. Despite its potential, challenges remain regarding its limited bioavailability and the scarcity of comprehensive human clinical trials. Curcumin emerges as a promising therapeutic adjunct in AD due to its multimodal neuroprotective benefits. However, further research is required to overcome challenges related to bioavailability and to establish effective dosing regimens in human subjects. Developing novel delivery systems and formulations may enhance curcumin's therapeutic potential in AD treatment.

Traditional Chinese medicine for gastric cancer: An evidence mapping

As a complementary and alternative therapy, traditional Chinese medicine (TCM) has been playing a significant role in gastric cancer treatment. Data from individual systematic reviews have not been comprehensively summarized, and the relationship between certain interventions and outcomes are ill-defined. This study aimed to analyze the advantages of TCM interventions for gastric cancer by the method of evidence mapping. We searched PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Chinese Scientific Journals Database, and Wanfang Database for systematic reviews of TCM treating gastric cancer up to December 31, 2023. We used Excel, Endnote 20, and Python software for the analysis of incorporated studies. We assessed the quality of included SRs by AMSTAR-2 and performed evidence mapping including 89 SRs, 1648 RCTs and 122,902 patients, identifying 47 types of interventions and 39 types of outcomes. From a visual overview, we displayed that most SRs reported beneficial effects in improving short- and long-term survival, myelosuppression, and immune function, even though the quality of evidence was generally low. The benefits of Brucea javanica Oil Emulsion Injection, ShenQiFuZheng Injection, XiaoAiPing, Astragalus-Containing TCM and Guben Xiaoji Therapy were found the most solid in corresponding aspects. Our findings suggest that although more rigorous clinical trials and SRs are needed to identify the precise effectiveness, integrating such evidence into clinical care of gastric cancer is expected to be beneficial.

Effect and mechanism of quercetin or quercetin-containing formulas against COVID-19: From bench to bedside

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the global coronavirus disease 2019 (COVID-19) pandemic since 2019. Immunopathogenesis and thromboembolic events are central to its pathogenesis. Quercetin exhibits several beneficial activities against COVID-19, including antiviral, anti-inflammatory, immunomodulatory, antioxidative, and antithrombotic effects. Although several reviews have been published, these reviews are incomplete from the viewpoint of translational medicine. The authors comprehensively evaluated the evidence of quercetin against COVID-19, both basically and clinically, to apply quercetin and/or its derivatives in the future. The authors searched the PubMed, Embase, and the Cochrane Library databases without any restrictions. The search terms included COVID-19, SARS-CoV-2, quercetin, antiviral, anti-inflammatory, immunomodulatory, thrombosis, embolism, oxidative, and microbiota. The references of relevant articles were also reviewed. All authors independently screened and reviewed the quality of each included manuscript. The Cochrane Risk of Bias Tool, version 2 (RoB 2) was used to assess the quality of the included randomized controlled trials (RCTs). All selected studies were discussed monthly. The effectiveness of quercetin against COVID-19 is not solid due to methodological flaws in the clinical trials. High-quality studies are also required for quercetin-containing traditional Chinese medicines. The low bioavailability and highly variable pharmacokinetics of quercetin hinder its clinical applications. Its positive impact on immunomodulation through reverting dysbiosis of gut microbiota still lacks robust evidence. Quercetin against COVID-19 does not have tough clinical evidence. Strategies to improve its bioavailability and/or to develop its effective derivatives are needed. Well-designed RCTs are also crucial to confirm their effectiveness in the future.

The effect of pomegranate juice supplementation on C-reactive protein levels: GRADE-assessed systematic review and dose-response updated meta-analysis of data from randomized controlled trials

Pomegranate juice (PJ) has a possible anti-inflammatory effect because of its polyphenol content and antioxidants. However, the anti-inflammatory effect of PJ in randomized controlled trials (RCTs) has not been consistent. A previous meta-analysis conducted in 2016 reported a nonsignificant lowering effect of PJ on C-reactive protein (CRP) levels. This systematic review and meta-analysis aim to update the pooled effect size of PJ supplementation on CRP levels in RCT studies. PubMed, Scopus, and Web of Science databases were comprehensively searched until July 2023. Eligible studies were found by screening, their relevant data was extracted, and a risk of bias assessment was performed. The pooled effect size was calculated using a random effect model as the weighted mean difference (WMD) with a 95% confidence interval. This systematic review included 11 studies with 13 effect sizes and 696 participants. Meta-analysis showed that PJ supplementation led to a significant decrease in CRP levels compared to control groups (WMD: -2.55 mg/L; 95%CI: -3.44 to -1.66; p < 0.001). Subgroup analysis demonstrated the significant reduction effect of PJ on CRP levels in studies conducted on the both sexes or only females as well as Iranian population, individuals with 40 years≤, type 2 diabetes, polycystic ovary syndrome, or trials that intervened with PJ dosage of <250 ml/day. Meta-regression and dose-response analysis reported a nonsignificant linear and nonlinear relationship between intervention characteristics (duration and dose of PJ) and CRP changes. The current meta-analysis revealed that PJ supplemantation has a beneficial effect in improving CRP levels. It is recommended to understand this effect better, and find the optimal dose and duration of PJ supplementation to reduce CRP levels in the blood, and repeat meta-analysis after related RCTs are available. For the final proof of these effects, more detailed human studies are needed.

TIRPnet: Risk prediction of traditional Chinese medicine ingredients based on a deep neural network

ETHNOPHARMACOLOGICAL RELEVANCE

Traditional Chinese medicine (TCM) has a history of over 3000 years of medical practice. Due to the complex ingredients and unclear pharmacological mechanism of TCM, it is very difficult to predict its risks. With the increase in the number and severity of spontaneous reports of adverse drug reactions (ADRs) of TCM, its safety has received widespread attention.

AIM OF THE STUDY

In this study, we proposed a framework based on deep learning to predict the probability of adverse reactions caused by TCM ingredients and validated the model using real-world data.

MATERIALS AND METHODS

The spontaneous reporting data from Jiangsu Province of China was selected as the research data, which included 72,561 ADR reports of TCMs. All the ingredients of these TCMs were collected from the medical website and correlated with the corresponding ADRs. Then, a risk prediction model was constructed based on a deep neural network (DNN), named TIRPnet. Based on one-hot encoded data, our model achieved the optimal performance by fine-tuning some hyperparameters. The ten most commonly used TCM ingredients and their ADRs were collected as the test set to evaluate their performance as objective criteria.

RESULTS

TIRPnet was constructed as a 7-layer DNN. The experimental results showed that TIRPnet performs excellently in all indicators, with a sensitivity of 0.950, specificity of 0.995, accuracy of 0.994, precision of 0.708, and F1 of 0.811.

CONCLUSIONS

The proposed TIRPnet owns the ability to predict the ADRs of a single TCM ingredient by learning a large number of TCM-related spontaneous reports, which can help doctors design safe prescriptions and provide technical support for the pharmacovigilance of TCM.

Insights into the anti-Candida albicans properties of natural phytochemicals: An in vitro and in vivo investigation

Invasive candidiasis, attributed to Candida albicans, has long been a formidable threat to human health. Despite the advent of effective therapeutics in recent decades, the mortality rate in affected patient populations remains discouraging. This is exacerbated by the emergence of multidrug resistance, significantly limiting the utility of conventional antifungals. Consequently, researchers are compelled to continuously explore novel solutions. Natural phytochemicals present a potential adjunct to the existing arsenal of agents. Previous studies have substantiated the efficacy of phytochemicals against C. albicans. Emerging evidence also underscores the promising application of phytochemicals in the realm of antifungal treatment. This review systematically delineates the inhibitory activity of phytochemicals, both in monotherapy and combination therapy, against C. albicans in both in vivo and in vitro settings. Moreover, it elucidates the mechanisms underpinning the antifungal properties, encompassing (i) cell wall and plasma membrane damage, (ii) inhibition of efflux pumps, (iii) induction of mitochondrial dysfunction, and (iv) inhibition of virulence factors. Subsequently, the review introduces the substantial potential of nanotechnology and photodynamic technology in enhancing the bioavailability of phytochemicals. Lastly, it discusses current limitations and outlines future research priorities, emphasizing the need for high-quality research to comprehensively establish the clinical efficacy and safety of phytochemicals in treating fungal infections. This review aims to inspire further contemplation and recommendations for the effective integration of natural phytochemicals in the development of new medicines for patients afflicted with C. albicans.

Effects and safety of resveratrol supplementation in older adults: A comprehensive systematic review

Resveratrol (RSV) has garnered significant attention in recent years due to its potential benefits against chronic diseases. However, its effects and safety in older adults have not been comprehensively studied. This study aimed to determine the effects and safety of RSV supplementation in older adults. MEDLINE/PubMed, Scopus, and Web of Science databases were comprehensively searched for eligible studies. Studies were enrolled if they were randomized clinical trials and had incorporated RSV supplementation for older adults. Two independent authors conducted the literature search, and eligibility was determined according to the PICOS framework. Study details, intervention specifics, and relevant outcomes were collected during the data collection. The Cochrane RoB-2 tool was used to evaluate the risk of bias. This review included 10 studies. The combination of RSV and exercise improved exercise adaptation and muscle function in healthy older adults and physical performance and mobility measures in individuals with functional limitations. RSV showed potential neuroprotective effects in patients with Alzheimer's disease. In overweight individuals, RSV demonstrated a positive impact on cognitive function, but it increased some biomarkers of cardiovascular disease risk at high doses. In older adults with diabetes and those with peripheral artery disease (PAD), RSV was not more effective than placebo. No study reported significant adverse events following RSV treatment. RSV can improve various health parameters in age-related health conditions. However, the optimal dosage, long-term effects, and potential interactions with medications still need to be investigated through well-designed RCTs.

Impact of Chinese herbal medicine on sarcopenia in enhancing muscle mass, strength, and function: A systematic review and meta-analysis of randomized controlled trials

Sarcopenia has become important to the public health with the increase in the aging population in society. However, the therapeutic effects of conventional approaches, including pharmacotherapy, exercise, and nutritional intervention, are far from satisfactory. Chinese herbal medicine is a new treatment format with interesting possibilities in sarcopenia has been widely practiced. The study aims to explore the effectiveness of Chinese herbal medicine in sarcopenia. We comprehensively searched the following electronic databases: Medline, EMBASE, APA PsycInfo, Cochrane Library, Web of Science, PubMed, and Chinese database from the establishment of the database to December 2022 (no language restrictions). Randomized controlled clinical studies on the use of Chinese herbal medicine in sarcopenia were selected in compliance with PRISMA guidelines. Review Manager and Stata were used for statistical analysis and the mean difference and standardized mean difference were adopted. Of 277 identified studies, 17 were eligible and included in our analysis (N = 1440 participants). The results showed that Chinese herbal medicine can improve total efficiency (RR = 1.29, 95% CI [1.21, 1.36], p < 0.00001) in sarcopenia and enhance muscle mass (SMD = 1.02, 95% CI [0.55, 1.50], p < 0.0001), and muscle strength measured by grip strength (SMD = 0.66, 95% CI [0.36, 0.96], p < 0.0001), measured by 60°/s knee extension peak TQ (MD = 5.63, 95% CI [-0.30, 11.57], p = 0.06) and muscle function measured by 6-meter walking speed (SMD = 1.34, 95% CI [0.60, 2.08], p = 0.0004), measured by the short physical performance battery of 1.50%, 95% CI (1.05, 1.95), measured by the EuroQoL 5-dimension of (SMD = 0.27, 95% CI [-0.10, 0.65], p = 0.16), suggesting that Chinese herbal medicine alone or combined with conventional treatment has ameliorating effect on sarcopenia. Chinese herbal medicine is a potential therapeutic strategy in sarcopenia. The funnel plot and Egger's test indicated publication bias. To confirm our conclusions, further high-quality studies should be conducted.

Targeting epidermal growth factor receptor and its downstream signaling pathways by natural products: A mechanistic insight

The epidermal growth factor receptor (EGFR) is a transmembrane receptor tyrosine kinase (RTK) that maintains normal tissues and cell signaling pathways. EGFR is overactivated and overexpressed in many malignancies, including breast, lung, pancreatic, and kidney. Further, the EGFR gene mutations and protein overexpression activate downstream signaling pathways in cancerous cells, stimulating the growth, survival, resistance to apoptosis, and progression of tumors. Anti-EGFR therapy is the potential approach for treating malignancies and has demonstrated clinical success in treating specific cancers. The recent report suggests most of the clinically used EGFR tyrosine kinase inhibitors developed resistance to the cancer cells. This perspective provides a brief overview of EGFR and its implications in cancer. We have summarized natural products-derived anticancer compounds with the mechanistic basis of tumor inhibition via the EGFR pathway. We propose that developing natural lead molecules into new anticancer agents has a bright future after clinical investigation.

Effects of silymarin supplementation on liver and kidney functions: A systematic review and dose-response meta-analysis

It is suggested that supplementation with silymarin (SIL) has beneficial impacts on kidney and liver functions. This systematic review and dose-response meta-analysis assessed the impact of SIL administration on certain hepatic, renal, and oxidative stress markers. A systematic search was conducted in various databases to identify relevant trials published until January 2023. Randomized controlled trials (RCTs) that evaluated the effects of SIL on kidney and liver markers were included. A random-effects model was used for the analysis and 41 RCTs were included. The pooled results indicated that SIL supplementation led to a significant reduction in serum levels of alkaline phosphatase, alanine transaminase, creatinine, and aspartate aminotransferase, along with a substantial elevation in serum glutathione in the SIL-treated group compared to their untreated counterparts. In addition, there was a nonsignificant decrease in serum levels of gamma-glutamyl transferase, malondialdehyde (MDA), total bilirubin, albumin (Alb), total antioxidant capacity, and blood urea nitrogen. Sub-group analyses revealed a considerable decline in MDA and Alb serum values among SIL-treated participants with liver disease in trials with a longer duration (≥12 weeks). These findings suggest that SIL may ameliorate certain liver markers with potential hepatoprotective effects, specifically with long-term and high-dose supplementation. However, its nephroprotective effects and impact on oxidative stress markers were not observed. Additional high-quality RCTs with longer durations are required to determine the clinical efficacy of SIL supplementation on renal and oxidative stress markers.

Effect of proanthocyanidins on blood lipids: A systematic review and meta-analysis

Proanthocyanidins (PCs) are natural antioxidant polyphenols and their effect on the regulation of blood lipids is still controversial. This study was conducted to evaluate the effect of PCs on lipid metabolism. We searched PubMed, Embase, Web of Science, Chinese biomedical literature service system, China National Knowledge Internet, and Wanfang Data with no time restriction until March 18, 2022, using various forms of "proanthocyanidins" and "blood lipid" search terms. Randomized controlled trials investigating the relationship between PCs and lipid metabolism were included. The standard system of Cochrane Collaboration was used to assess the quality of studies. We standardized mean differences (SMDs) with 95% confidence interval (CI) using the random-effects model, Cohen approach. Seventeen studies (17 trials, N = 1138) fulfilled the eligibility criteria. PCs significantly reduced triglyceride, and increased recombinant apolipoprotein A1. Subgroup analysis showed a significant reduction in triglycerides in older adults (≥60 years) and total cholesterol for participants who were not overweight or obese (body mass index <24). An intervention duration of greater than 8 weeks reduced triglyceride and low-density lipoprotein cholesterol levels but increased high-density lipoprotein cholesterol. Different doses of PCs could regulate triglycerides, high-density lipoprotein cholesterol and total cholesterol. PCs have beneficial effects on circulating lipids and may represent a new approach for treating or preventing lipid metabolism disorders. However, more high-quality studies are needed to confirm these results.

The effects of pomegranate consumption on blood pressure in adults: A systematic review and meta-analysis

Considering the main component of cardiovascular disease and due to the high prevalence of hypertension, controlling blood pressure is required in individuals with various health conditions. Randomized clinical trials (RCTs) which studied the effects of pomegranate consumption on blood pressure have shown inconsistent findings. As a result, we intended to assess the effects of pomegranate consumption on systolic (SBP) and diastolic (DBP) blood pressure in adults. Systematic literature searches up to January 2024 were carried out using electronic databases, including PubMed, Web of Science, and Scopus, to identify eligible RCTs assessing the effects of pomegranate on blood pressure as an outcome. All the individuals who took part in our research were adults who consumed pomegranate in different forms as part of the study intervention. Heterogeneity tests of the selected trials were performed using the I2 statistic. Random effects models were assessed based on the heterogeneity tests, and pooled data were determined as the weighted mean difference (WMD) with a 95% confidence interval (CI). Of 2315 records, 22 eligible RCTs were included in the current study. Our meta-analysis of the pooled findings showed that pomegranate consumption significantly reduced SBP (WMD: -7.87 mmHg; 95% CI: -10.34 to -5.39; p < 0.001) and DBP (WMD: -3.23 mmHg; 95% CI: -5.37 to -1.09; p = 0.003). Individuals with baseline SBP > 130 mmHg had a significantly greater reduction in SBP compared to individuals with baseline SBP < 130 mmHg. Also, there was a high level of heterogeneity among studies (SBP: I2 = 90.0% and DBP: I2 = 91.8%). Overall, the results demonstrated that pomegranate consumption lowered SBP and DBP in adults. Although our results suggest that pomegranate juice may be effective in reducing blood pressure in the pooled data, further high-quality studies are needed to demonstrate the clinical efficacy of pomegranate consumption.

Impacts of Supplementation with Silymarin on Cardiovascular Risk Factors: A Systematic Review and Dose-Response Meta-Analysis

It has been suggested that silymarin (SIL) supplementation has positive effects on cardiovascular health and reduces the risk of cardiometabolic syndrome (CMS). This systematic review and dose-response meta-analysis assessed the impacts of SIL administration on cardiovascular risk factors. A systematic search of multiple databases was performed to identify eligible controlled trials published up to January 2023. The analysis used a random-effects model and included 33 trials with 1943 participants. It was revealed that SIL supplementation led to a notable reduction in serum levels of fasting blood glucose (FBG) (weighted mean difference (WMD): -21.68 mg/dL, 95% CI: -31.37, -11.99; p < 0.001), diastolic blood pressure (DBP) (WMD: -1.25 mmHg; 95% CI: -2.25, -0.26; p = 0.013), total cholesterol (TC) (WMD: -13.97 mg/dL, 95% CI: -23.09, -4.85; p = 0.003), triglycerides (TG) (WMD: -26.22 mg/dL, 95% CI: -40.32, -12.12; p < 0.001), fasting insulin (WMD: -3.76 mU/mL, 95% CI: -4.80, -2.72; p < 0.001), low-density lipoprotein (LDL) (WMD: -17.13 mg/dL, 95% CI: -25.63, -8.63; p < 0.001), and hemoglobin A1C (HbA1c) (WMD: -0.85%, 95% CI: -1.27, -0.43; p < 0.001) in the SIL-treated groups compared to their untreated counterparts. In addition, there were no substantial differences in body mass index (BMI), systolic blood pressure (SBP), C-reactive protein (CRP), body weight, and high-density lipoprotein (HDL) between the two groups. These outcomes suggest that SIL consumption reduces certain CMS risk factors and has favorable impacts on lipid and glycemic profiles with potential hypotensive effects. These findings should be supported by additional trials with larger sample sizes and longer durations.

Current understanding and future directions of cruciferous vegetables and their phytochemicals to combat neurological diseases

Neurological disorders incidences are increasing drastically due to complex pathophysiology, and the nonavailability of disease-modifying agents. Several attempts have been made to identify new potential chemicals to combat these neurological abnormalities. At present, complete abolishment of neurological diseases is not attainable except for symptomatic relief. However, dietary recommendations to help brain development or improvement have increased over the years. In recent times, cruciferous vegetables and their phytochemicals have been identified from preclinical and clinical investigations as potential neuroprotective agents. The present review highlights the beneficial effects and molecular mechanisms of phytochemicals such as indole-3-carbinol, diindolylmethane, sulforaphane, kaempferol, selenium, lutein, zeaxanthin, and vitamins of cruciferous vegetables against neurological diseases including Parkinson's disease, Alzheimer's disease, stroke, Huntington's disease, autism spectra disorders, anxiety, depression, and pain. Most of these cruciferous phytochemicals protect the brain by eliciting antioxidant, anti-inflammatory, and antiapoptotic properties. Regular dietary intake of cruciferous vegetables may benefit the prevention and treatment of neurological diseases. The present review suggests that there is a lacuna in identifying the clinical efficacy of these phytochemicals. Therefore, high-quality future studies should firmly establish the efficacy of the above-mentioned cruciferous phytochemicals in clinical settings.

Efficacy of plant-derived dietary supplements in improving overall menopausal symptoms in women: An updated systematic review and meta-analysis

This updated systematic review and meta-analysis aims to confirm the effectiveness of plant-based supplements in improving overall menopausal symptoms and vasomotor symptoms. A systematic review of the literature was conducted by searching the PubMed/MEDLINE, Web of Science, EMBASE, and CENTRAL databases up to June 2022. Randomized placebo-controlled clinical trials that evaluated the effects of dietary supplements on menopausal symptoms were included. Outcome measures included daily hot flash frequency, Kupperman's index, Menopause Rating Scale, and Greene Climacteric Scale. Pooled data were analyzed using a fixed-effects model and expressed as a weighted mean difference with a 95% confidence interval for continuous outcomes. For qualitative assessment, 67 studies were selected. For quantitative assessment, 54 reports were obtained from 61 studies. The study participants were peri- or postmenopausal women aged 38-85, most of whom experienced hot flashes as a menopausal symptom. The investigational products included 28 soy-derived, 6 red clover-derived, and 28 other plant-derived supplements. Qualitative assessment revealed that approximately 76% of the studies were generally of fair or good quality, whereas 24% were of low quality. Meta-analysis results indicated significant improvements in all questionnaire scores, including hot flash frequency, in the dietary supplement group compared with the placebo group. Comprehensive evaluation using different questionnaire tools showed that the various plant-derived dietary supplements can significantly alleviate menopausal symptoms. However, further rigorous studies are needed to determine the association of plant-derived dietary supplements with menopausal health because of the general suboptimal quality and heterogeneous nature of current evidence.

Effects of purified anthocyanins supplementation on serum concentration of inflammatory mediators: A systematic review and dose-response meta-analysis on randomized clinical trials

Anthocyanins, due to their antioxidant effects, are candidates to reduce inflammation and the risk of inflammatory diseases. Therefore, through conducting a systematic review and meta-analysis, we tried to find the effect of purified anthocyanins on serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). Databases including, ISI Web of Science, Scopus, ClinicalTrials.gov, PubMed, and Cochrane Library were searched up to June 2023. The meta-analysis was done by calculating mean differences and their standard deviations. Calculating the statistical heterogeneity of intervention effects was performed through I-squared statistics and Cochran's Q test. The pooled estimate showed a significant decrease in serum levels of CRP, TNF-α, and IL-6 (weighted mean difference (WMD) = -0.12 mg/L, 95% confidence interval (CI) = -0.21 to -0.02, p = 0.013; WMD = -1.37 pg/mL, 95% CI = -1.79 to -0.96; p < 0.001; WMD = -1.43 pg/mL, 95% CI = -1.87 to -1.00; p < 0.001, respectively). Subgroup analysis results revealed purified anthocyanins significantly decreased serum levels of CRP among participants with serum levels of CRP≥1.52 mg/L, at-risk/unhealthy status, and in trials with intervention duration ≥84 days, anthocyanins dose ≥320 mg/day, and sample size ≥85 subjects. Regarding TNF-α and IL-6, out results showed that there was a significant effect of purified anthocyanins on serum levels of TNF-α and IL-6 in most subgroups. The results of our study indicated that purified anthocyanins significantly decreased serum levels of CRP, TNF-α, and IL-6. However, further high-quality studies are needed to firmly establish the efficacy of purified anthocyanins.

Diet and Lipid-Lowering Nutraceuticals in Pediatric Patients with Familial Hypercholesterolemia

Familial hypercholesterolemia is a genetically determined disease characterized by elevated plasma total and LDL cholesterol levels from the very first years of life, leading to early atherosclerosis. Nutritional intervention is the first-line treatment, complemented with nutraceuticals and drug therapy when necessary. Nutraceuticals with a lipid-lowering effect have been extensively studied in the past few decades, and have been recently included in international guidelines as a complement to nutritional and pharmacological treatment in subjects with dyslipidemia. In this review, we explore current nutritional interventions for dyslipidemia in childhood, with a specific focus on the main nutraceuticals studied for treating severe dyslipidemia in pediatric patients. Additionally, we briefly describe their primary mechanisms of action and highlight the advantages and risks associated with the use of lipid-lowering nutraceuticals in childhood.

The effects of blueberry and cranberry supplementation on blood pressure in patients with cardiovascular diseases: A systematic review and meta-analysis of randomized clinical trials

Blueberries and cranberries are berry fruits with the highest number of randomized clinical trials (RCTs) focusing on blood pressure (BP). This systematic review and meta-analysis of RCTs analyzed the effects of blueberry and cranberry supplementation alone and in concert with systolic BP (SBP) and diastolic BP (DBP) in patients with cardiometabolic diseases. The searches were performed until August 2023 in the following databases: PubMed, Scopus, Web of Science, Cochrane, and Embase. Studies that examined the effects of blueberry or cranberry intake/supplementation were included. The risk of bias was evaluated using the Rob 2 scale. A meta-analysis was performed to estimate the effects of blueberry and cranberry supplementation on BP levels in patients with cardiometabolic diseases. A total of 17 articles were included, from which two found significant results from blueberry and/or cranberry supplementation in reducing BP. Pooled results revealed statistically non-significant reductions of -0.81 mm Hg for SBP (95% confidence interval [CI]: -2.26, 0.63; I2  = 0%) and -0.15 mm Hg for DBP (95% CI: -1.36, 1.05; I2  = 27%). Blueberry and/or cranberry supplementation had neutral effects on SBP and DBP in patients with cardiometabolic diseases, regardless of duration or age. Further high-quality studies are needed to firmly establish clinical efficacy.

The effect of phytosterol supplementation on lipid profile: A critical umbrella review of interventional meta-analyses

Despite multiple investigations assessing the impact of phytosterol supplementation on serum lipid levels, there is still a great deal of debate regarding the benefits of this intervention in the management of dyslipidemia. Therefore, we aimed at clarifying this dilemma by conducting the present umbrella review of interventional meta-analyses. Scopus, PubMed, Web of Science, and EMBASE were used to search for pertinent publications on the effect of phytosterol supplementation on the lipid profile in humans up to June 2023. To compute the overall effect size (ES) and confidence intervals (CI), the random-effects model was used. The I2 statistic and Cochrane's Q-test were applied to estimate the heterogeneity among the studies. Seventeen meta-analyses with 23 study arms were included in the umbrella meta-analysis. Data pooled from the 23 eligible arms revealed that phytosterol supplementation reduces low-density lipoprotein cholesterol (LDL-C) (ES = -11.47 mg/dL; 95% CI: -12.76, -10.17, p < 0.001), total cholesterol (TC) (ES = -13.02 mg/dL; 95% CI: -15.68, -10.37, p < 0.001), and triglyceride (TG) (ES = -3.77 mg/dL; 95% CI: -6.04, -1.51, p = 0.001). Subgroup analyses showed that phytosterol administration with dosage ≥2 g/day and duration over 8 weeks and in hypercholesterolemic subjects was more likely to decrease LDL-C, TC, and TG. Phytosterol administration did not significantly modify HDL-C (ES = 0.18 mg/dL; 95% CI: -0.13, -0.51, p = 258) levels when compared to controls. The present umbrella meta-analysis confirms that phytosterol administration significantly reduces LDL-C, TC, and TG, with a greater effect with doses of ≥2 g/day and treatment duration >8 weeks, suggesting its possible application as a complementary therapy for cardiovascular risk reduction. Further studies are needed to determine the efficacy of phytosterols in patients with specific health conditions, as well as to ascertain the adverse effects, the maximum tolerable dose, and the maximum recommended duration of phytosterol administration.

Anticancer activity and other biomedical properties of β-sitosterol: Bridging phytochemistry and current pharmacological evidence for future translational approaches

Sterols, including β-sitosterol, are essential components of cellular membranes in both plant and animal cells. Despite being a major phytosterol in various plant materials, comprehensive scientific knowledge regarding the properties of β-sitosterol and its potential applications is essential for scholarly pursuits and utilization purposes. β-sitosterol shares similar chemical characteristics with cholesterol and exhibits several pharmacological activities without major toxicity. This study aims to bridge the gap between phytochemistry and current pharmacological evidence of β-sitosterol, focusing on its anticancer activity and other biomedical properties. The goal is to provide a comprehensive understanding of β-sitosterol's potential for future translational approaches. A thorough examination of the literature was conducted to gather relevant information on the biological properties of β-sitosterol, particularly its anticancer therapeutic potential. Various databases were searched, including PubMed/MedLine, Scopus, Google Scholar, and Web of Science using appropriate keywords. Studies investigating the effects of β-sitosterol on different types of cancer were analyzed, focusing on mechanisms of action, pharmacological screening, and chemosensitizing properties. Modern pharmacological screening studies have revealed the potential anticancer therapeutic properties of β-sitosterol against various types of cancer, including leukemia, lung, stomach, breast, colon, ovarian, and prostate cancer. β-sitosterol has demonstrated chemosensitizing effects on cancer cells, interfering with multiple cell signaling pathways involved in proliferation, cell cycle arrest, apoptosis, survival, metastasis invasion, angiogenesis, and inflammation. Structural derivatives of β-sitosterol have also shown anti-cancer effects. However, research in the field of drug delivery and the detailed mode of action of β-sitosterol-mediated anticancer activities remains limited. β-sitosterol, as a non-toxic compound with significant pharmacological potential, exhibits promising anticancer effects against various cancer types. Despite being relatively less potent than conventional cancer chemotherapeutics, β-sitosterol holds potential as a safe and effective nutraceutical against cancer. Further comprehensive studies are recommended to explore the biological properties of β-sitosterol, including its mode of action, and develop novel formulations for its potential use in cancer treatment. This review provides a foundation for future investigations and highlights the need for further research on β-sitosterol as a potent superfood in combating cancer.

Plant-derived virulence arresting drugs as novel antimicrobial agents: Discovery, perspective, and challenges in clinical use

Antimicrobial resistance (AMR) emerges as a severe crisis to public health and requires global action. The occurrence of bacterial pathogens with multi-drug resistance appeals to exploring alternative therapeutic strategies. Antivirulence treatment has been a positive substitute in seeking to circumvent AMR, which aims to target virulence factors directly to combat bacterial infections. Accumulated evidence suggests that plant-derived natural products, which have been utilized to treat infectious diseases for centuries, can be abundant sources for screening potential virulence-arresting drugs (VADs) to develop advanced therapeutics for infectious diseases. This review sums up some virulence factors and their actions in various species of bacteria, as well as recent advances pertaining to plant-derived natural products as VAD candidates. Furthermore, we also discuss natural VAD-related clinical trials and patents, the perspective of VAD-based advanced therapeutics for infectious diseases and critical challenges hampering clinical use of VADs, and genomics-guided identification for VAD therapeutic. These newly discovered natural VADs will be encouraging and optimistic candidates that may sustainably combat AMR.

Indigofera suffruticosa aerial parts extract induce G2/M arrest and ATR/CHK1 pathway in Jurkat cells

BACKGROUND

Indigofera suffruticosa Mill. is used as a folk medicine for treating patients with leukemia, however very little is known regarding the molecular mechanism of its anti-leukemic activity and the chemical profile of the active extract. The present study aimed to reveal the molecular effect of I. suffruticosa aerial parts extract (ISAE) on leukemia cells and its chemical constituents.

METHODS

Cytotoxicity of ISAE were determined by resazurin viability assay, multitox - Glo multiplex cytotoxicity assay, and Annexin V staining assay. Cell cycle profiles were revealed by propidium iodide staining assay. The effects of ISAE on G2/M arrest signaling and DNA damage were evaluated by Western blot assay and phospho-H2A.X staining assay. The chemical profile of ISAE were determined by tandem mass spectroscopy and molecular networking approach.

RESULTS

We showed that the acute lymphoblastic leukemia cell line Jurkat cell was more responsive to ISAE treatment than other leukemia cell lines. In contrast, ISAE did not induce cytotoxic effects in normal fibroblast cells. Cell cycle analysis revealed that ISAE triggered G2/M arrest in Jurkat cells in dose- and time-dependent manners. Elevation of annexin V-stained cells and caspase 3/7 activity suggested ISAE-induced apoptosis. Furthermore, ISAE alone could increase the phosphorylation of CDK1 at Y15 and activate the ATR/CHK1/Wee1/CDC25C signaling pathway. However, the addition of caffeine, a widely used ATR inhibitor to ISAE, reduced the phosphorylation of ATR, CHK1, and CDK1, as well as G2/M arrest in Jurkat cells. Moreover, increased phospho-H2A.X stained cells indicated the involvement of DNA damage in the anti-leukemic effect of ISAE. Finally, qualitative analysis using UPLC-tandem mass spectroscopy and molecular networking revealed that tryptanthrin was the most abundant organoheterocyclic metabolite in ISAE. At equivalent concentrations to ISAE, tryptanthrin induced G2/M arrest of Jurkat cells, which can be prevented by caffeine.

CONCLUSIONS

ISAE causes G2/M arrest via activating ATR/CHK1/CDK1 pathway and tryptanthrin is one of the active components of ISAE. Our findings provide subtle support to the traditional use of I. suffruitcosa in leukemia management in folk medicine.

Pomegranate effects on the health aspects of women during peri- and postmenopause: A systematic review and meta-analysis

Pomegranate is widely used to preserve human health and help prevent many kinds of diseases. This study aims to review and assess the effects of pomegranate on women's health during and after menopause. PubMed, Web of science, Cochrane, Scopus, and Google Scholar were searched up to the end of 2022 with no language or study type restriction. All types of clinical research studies (randomized clinical trial [RCT], pre-post, case report, and case series) were included. The Cochrane RoB 2.0 tool was used for quality assessment of RCTs. A summary of intervention's effects for each study was provided by calculating standardized mean differences and accompanying 95% confidence interval using random effect model. Weighted mean differences and heterogeneity between studies were assessed using Hedges's method and Cochran's Q test, respectively. Pomegranate can significantly improve hot flashes severity and menopause symptoms and decrease FSH. It significantly improves high-density lipoprotein but not low-density lipoprotein, body mass index, and weight. Most of our results are inconclusive, and the small sample sizes and the lack of blinding and randomization have led to an increased risk of bias. Pomegranate can decrease menopause symptoms, but more well-designed studies, with bigger sample sizes are needed to establish its other clinical benefits for menopausal women.

Effects of sumac supplementation on lipid profile: A systematic review and meta-analysis of randomized controlled trials

This systematic review aimed to gather data on the effects of sumac supplementation on lipid profile. A systematic literature search was carried out using electronic databases (PubMed, Scopus, and Web of Science) up to March 2023 to identify eligible randomized controlled trials (RCTs) assessing the effects of sumac intake on lipid profile as an outcome. All participants enrolled in our study were adult individuals who consumed sumac, in various forms, as an intervention. The included articles were assessed using the Cochrane risk of bias assessment tool. Heterogeneity tests of the selected trials were performed using the I2 statistic. Random effects models were assessed based on the heterogeneity tests, and pooled data were determined as the weighted mean difference with a 95% confidence interval. In total, seven RCTs with a total sample size of 570 subjects were included. This study found a significant decrease in total cholesterol (TC) (weighted mean difference [WMD]: -10.01 mg/dL; 95% CI: -18.67, -1.34), triglyceride (TG) (WMD: -8.52 mg/dL; 95% CI: -14.79, -2.25), and low-density lipoprotein (LDL)-C levels (WMD: -9.25 mg/dL; 95% CI: -14.56, -3.93); Moreover, a significant increase was observed in high-density lipoprotein (HDL)-C concentration (WMD: 2.97 mg/dL; 95% CI: 0.75, 5.19). The reduction in TG and TC was greater in studies with a duration of ≥12 compared to <12 weeks. The increase in HDL-C was greater in participants with an intervention duration of ≥12 compared to <12 weeks. Moreover, subgroup analysis based on the dose of sumac suggested a significant reduction in TC and LDL, specifically for doses below 3 g. Consumption of sumac significantly decreased serum TC, LDL-C, and TG concentrations. This study suggested significantly positive effects on HDL-C by intake of sumac. Longer interventions (>12 weeks) have a more favorable impact on TC, LDL-C, and HDL-C, while sumac doses below 3 g/day show greater effects on TC and LDL-C. These findings underscore the potential of sumac supplementation as a valuable approach to lipid profile management.

Galangin: A food-derived flavonoid with therapeutic potential against a wide spectrum of diseases

Galangin is an important flavonoid with natural activity, that is abundant in galangal and propolis. Currently, various biological activities of galangin have been disclosed, including anti-inflammation, antibacterial effect, anti-oxidative stress and aging, anti-fibrosis, and antihypertensive effect. Based on the above bioactivities, more and more attention has been paid to the role of galangin in neurodegenerative diseases, rheumatoid arthritis, osteoarthritis, osteoporosis, skin diseases, and cancer. In this paper, the natural sources, pharmacokinetics, bioactivities, and therapeutic potential of galangin against various diseases were systematically reviewed by collecting and summarizing relevant literature. In addition, the molecular mechanism and new preparation of galangin in the treatment of related diseases are also discussed, to broaden the application prospect and provide reference for its clinical application. Furthermore, it should be noted that current toxicity and clinical studies of galangin are insufficient, and more evidence is needed to support its possibility as a functional food.

Effects of berberine and barberry on selected inflammatory biomarkers in adults: A systematic review and dose-response meta-analysis of randomized clinical trials

The previous meta-analysis showed an advantageous effect of berberine supplementation on interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), and serum C-reactive protein (CRP) concentrations; however, it is unknown the dosage that this component influences inflammatory biomarkers. A comprehensive search was done in Scopus, PubMed, and Web of Science until September 2022 to find randomized controlled trials (RCT) that assessed the effects of berberine/barberry on IL-6, TNF-α, and CRP in adults but not trials without a control group. Studies bias was assessed using RoB 2. A random-effects model was performed to calculate the weighted mean difference (WMD). A dose-dependent effect was calculated. Eighteen clinical trials with 1600 participants were included in the current meta-analysis. These interventions significantly mitigate IL-6 levels (-1.18 pg/mL), TNF-α levels (-3.72 pg/mL), and CRP levels (-1.33 mg/L). In addition, the non-linear analysis showed a significant lowering effect of berberine/barberry on IL-6 and TNF-α levels in doses <1000 mg/day and less than 5 weeks of intervention. There are limitations to our findings, including low-quality studies and significant heterogeneity. These interventions might be considered adjunct therapy to managing inflammation status. However, more investigation and high-quality evidence must be conducted to obtain more comprehensive and generalizable results.

Efficacy and safety of herbal medicines intervention for cachexia associated with cancer: A systematic review and meta-analysis

As a worldwide public health issue, cancer-induced cachexia can result in decreasing physical function and survival rate. However, the therapeutic effects of conventional approaches, including pharmacotherapy, exercise and nutritional intervention, are far from satisfactory. Herbal medicines (HMs), especially Traditional Chinese Medicine (TCM), are reported to effectively treat cachexia for centuries. The inclusion criteria of all participants in this study pointed to the diagnosis of cachexia, the trial group used herbal medicine (HM) in complementary and alternative medicine, etc. Twelve databases, including EMbase, PubMed, Web of science, Cochrane CENTRAL, CINAHL, CINAHLPlus, PsycINFO, AMED, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI), Wanfang and Chongqing VIP (CQVIP) were retrieved from inception to March 28, 2022. We conducted the meta-analysis utilizing RevMan 5.3. A trial sequential analysis (TSA) was conducted to assess the adequacy of the sample size for the outcomes. We have registered the protocol and the registration number was CRD42022336446. A total of 66 studies were included, containing 3654 patients diagnosed with cancer cachexia, of which 1833 patients were assigned to the trial group and 1821 patients were treated in the control group. Outcomes cover the primary indicator KPS (RR = 1.84, 95%CI = [1.61, 2.09], p < 0.00001), and other outcomes including adverse events rate (RR = 0.37, 95%CI = [0.23, 0.58], p < 0.0001), albumin (MD = 2.14, 95%CI = [1.56, 2.71], p < 0.00001), haemoglobin (MD = 4.88, 95%CI = [3.26, 6.50], p < 0.00001), TCM syndrome effect (MD = 1.47, 95%CI = [1.31, 1.65], p < 0.00001), effect of weight (RR = 1.62, 95%CI = [1.34, 1.95], p < 0.00001), effect of appetite (RR = 1.23, 95%CI = [1.13, 1.34], p < 0.00001), FAACT (RR = 7.81, 95%CI = [6.12, 9.50], p < 0.00001), PG-SGA (MD = -2.16, 95%CI = [-2.65, -1.67], p < 0.00001) and QOL (MD = 5.76, 95%CI = [4.04, 7.48], p < 0.00001), suggesting that HMs or HMs combined with conventional treatment have an ameliorating effect on cachexia in each respect. Subgroup analysis showed that the five HMs with the best effect on improving KPS and their optimal doses were Coicis Semen (Yiyiren) in 10 g group, Citri Reticulatae Pericarpium (Chenpi) in 15 g group, Dioscoreae Rhizoma (Shanyao) in 10 g group, Ophiopogonis Radix (Maidong) in 10 g group and Ginseng Radix Et Rhizoma (Renshen) in 20 g group. In addition, there were HM combinations of levels 2-6. Egger's test showed publication bias for five outcomes. HMs have a significant effect on improving cancer cachexia on FAACT, TCM syndrome, KPS, QOL, appetite, nutritional status (evaluated by PG-SGA scale), weight, levels of albumin and haemoglobin. And the Adverse events rate is less than that of Western Medicine. The herbs with the best curative effect and their optimal dose were Dioscoreae R. (10 g), Citri R.P. (15 g), Coicis S. (10 g), Ophiopogonis R. (10 g) and Ginseng R.E.R. (20 g). Due to the quality of included studies is not high, further high-quality studies are needed to firmly establish the clinical efficacy of HM.

The protective role of resveratrol in diabetic wound healing

Diabetic wounds are severe complications of diabetes mellitus (DM), which have difficulty in healing. Although diverse treatments have been used, the prognosis of diabetic wounds is not satisfactory; therefore, an effective therapy to accelerate diabetic wound healing is urgently needed. In our review, we summarized that resveratrol can promote diabetic wound healing by protecting against hyperglycemia, inflammation, oxidative stress, vascular pathology, infection, and peripheral neuropathy. To clarify it clearly, we highlighted its underlying mechanisms of protective effects of resveratrol against diabetic wounds, and high-quality studies are needed to firmly establish its clinical efficacy. Otherwise, with the development of material sciences, resveratrol can exert its therapeutic effectiveness efficiently; however, more high-quality studies are needed to confirm the clinical efficacy of resveratrol on diabetic wounds.

Mechanistic prospective and pharmacological attributes of quercetin in attenuation of different types of arthritis

Arthritis is a frequent autoimmune disease with undefined etiology and pathogenesis. Scientific community constantly fascinating quercetin (QUR), as it is the best-known flavonoid among others for curative and preventive properties against a wide range of diseases. Due to its multifaceted activities, the implementation of QUR against various types of arthritis namely, rheumatoid arthritis (RA), osteoarthritis (OA), gouty arthritis (GA) and psoriotic arthritis (PsA) has greatly increased in recent years. Many research evidenced that QUR regulates a wide range of pathways for instance NF-κB, MAK, Wnt/β-catenine, Notch, etc., that are majorly associated with the inflammatory mechanisms. Besides, the bioavailability of QUR is a major constrain to its therapeutic potential, and drug delivery techniques have experienced significant development to overcome the problem of its limited application. Hence, this review compiled the cutting-edge experiments on versatile effects of QUR on inflammatory diseases like RA, OA, GA and PsA, sources and bioavailability, therapeutic challenges, pharmacokinetics, clinical studies as well as toxicological impacts. The use of QUR in a health context would offer a tearing and potential therapeutic method, supporting the advancement of public health, particularly, of arthritic patients worldwide.

Association between cannabis use and risk of diabetes mellitus type 2: A systematic review and meta-analysis

BACKGROUND

Cannabis consumption exerts multiple effects on metabolism via various pathways, including glucose regulation and insulin secretion. Studies concerning the association between cannabis use and diabetes mellitus type 2 are discrepant.

OBJECTIVE

This study was conducted to evaluate the association between cannabis use and type 2 diabetes mellitus (T2DM).

SEARCH METHODS

We searched PubMed, Scopus, Embase, Proquest, Web of Science, and Cochrane Library with no time, language or study types restriction until July 1, 2022, using various forms of "cannabis" and "diabetes mellitus" search terms.

SELECTION CRITERIA

Randomized control trials, cohort, and case-control studies investigating the relationship between cannabis consumption and diabetes mellitus type 2 were included.

DATA COLLECTION AND ANALYSIS

The Newcastle-Ottawa scale was used to assess the quality of studies. We pooled odds ratio (OR) with 95% confidence interval (CI) using the random-effects model, generic inverse variance method, DerSimonian and Laird approach.

MAIN RESULTS

A meta-analysis of seven studies, containing 11 surveys and 4 cohorts, revealed that the odds of developing T2DM in individuals exposed to cannabis was 0.48 times (95% CI: 0.39 to 0.59) lower than in those without cannabis exposure.

CONCLUSIONS

A protective effect of cannabis consumption on the odds of diabetes mellitus type 2 development has been suggested. Yet given the considerable interstudy heterogeneity, the upward trend of cannabis consumption and cannabis legalization is recommended to conduct studies with higher levels of evidence.

Impact of pomegranate juice on blood pressure: A systematic review and meta-analysis

Despite the importance of polyphenol-rich fruits in decreasing cardiovascular mortality, the impact of pomegranate juice (PJ) on blood pressure is still unclear. To determine the effect of PJ on blood pressure. PubMed, Scopus, ISI Web of Science, and Cochrane Library were searched comprehensively using relevant keywords. All studies using pomegranate juice alone were included although limited to human studies and the English language. A random-effects model and the generic inverse variance approach were used to determine quantitative data synthesis. Meta-analysis of 14 clinical trials (n = 573 individuals) demonstrated a reduction in systolic BP (SBP) with pomegranate juice (MD: -5.02 mmHg, 95% CI: -7.55 to -2.48, p < 0.001). Effect of study duration showed pomegranate juice intake ≤2 months significantly decreased SBP (MD: -4.59 mmHg, 95% CI: -7.10 to -2.08, p < 0.001) and DBP (MD: -2.94 mmHg, 95% CI: -5.25 to -0.63, p = 0.01). Consumption of ≤300 mL pomegranate juice daily reduced SBP (MD: -6.11 mmHg, 95% CI: -9.22 to -3.00, p < 0.001). Counterintuitively, >300 mL/day of pomegranate juice showed no effect on SBP (MD: -3.28 mmHg, 95% CI: -6.85 to 0.27, p = 0.07) but a significant DBP reduction occurred (MD: -3.10 mmHg, 95% CI: -5.74 to -0.47, p = 0.02). Meta-regression showed that the SBP-lowering effect of pomegranate juice was associated with the dose of supplementation (p < 0.001). Pomegranate juice appeared to decrease SBP and DBP in a dose-dependent manner, but the benefit was lost after 2 months of pomegranate juice intake.

Medicinal plant molecules against hepatitis C virus: Current status and future prospect

Hepatitis C virus (HCV), a global malady, causes acute and chronic hepatitis leading to permanent liver damage, hepatocellular carcinoma, and death. Modern anti-HCV therapies are efficient, but mostly inaccessible for residents of underdeveloped regions. To innovate more effective treatments at affordable cost, medicinal plant-based products need to be explored. The aim of this article is to review plant constituents in the light of putative anti-HCV mechanisms of action, and discuss existing problems, challenges, and future directions for their potential application in therapeutic settings. One hundred sixty literatures were collected by using appropriate search strings via scientific search engines: Google Scholar, PubMed, ScienceDirect, and Scopus. Bibliography was prepared using Mendeley desktop software. We found a substantial number of plants that were reported to inhibit different stages of HCV life cycle. Traditional medicinal plants such as Phyllanthus amarus Schumach. and Thonn., Eclipta alba (L.) Hassk., and Acacia nilotica (L.) Delile exhibited strong anti-HCV activities. Again, several phytochemicals such as epigallocatechin-3-gallate, honokilol, punicalagin, and quercetin have shown broad-spectrum anti-HCV effect. We have presented promising phytochemicals like silymarin, curcumin, glycyrrhizin, and camptothecin for nanoparticle-based hepatocyte-targeted drug delivery. Nevertheless, only a few animal studies have been performed to validate the anti-HCV effect of these plant products. Again, insufficient clinical evaluation of the safety and effectiveness of herbal medications remain a problem. Selected plants products could be developed as novel therapeutics for HCV patients only after scrupulous evaluation of their safety and efficacy in a clinical set-up.

Mechanism of the antidiabetic action of Nigella sativa and Thymoquinone: a review

Introduction

Long used in traditional medicine, Nigella sativa (NS; Ranunculaceae) has shown significant efficacy as an adjuvant therapy for diabetes mellitus (DM) management by improving glucose tolerance, decreasing hepatic gluconeogenesis, normalizing blood sugar and lipid imbalance, and stimulating insulin secretion from pancreatic cells. In this review, the pharmacological and pharmacokinetic properties of NS as a herbal diabetes medication are examined in depth, demonstrating how it counteracts oxidative stress and the onset and progression of DM.

Methods

This literature review drew on databases such as Google Scholar and PubMed and various gray literature sources using search terms like the etiology of diabetes, conventional versus herbal therapy, subclinical pharmacology, pharmacokinetics, physiology, behavior, and clinical outcomes.

Results

The efficiency and safety of NS in diabetes, notably its thymoquinone (TQ) rich volatile oil, have drawn great attention from researchers in recent years; the specific therapeutic dose has eluded determination so far. TQ has anti-diabetic, anti-inflammatory, antioxidant, and immunomodulatory properties but has not proved druggable. DM's intimate link with oxidative stress, makes NS therapy relevant since it is a potent antioxidant that energizes the cell's endogenous arsenal of antioxidant enzymes. NS attenuates insulin resistance, enhances insulin signaling, suppresses cyclooxygenase-2, upregulates insulin-like growth factor-1, and prevents endothelial dysfunction in DM.

Conclusion

The interaction of NS with mainstream drugs, gut microbiota, and probiotics opens new possibilities for innovative therapies. Despite its strong potential to treat DM, NS and TQ must be examined in more inclusive clinical studies targeting underrepresented patient populations.

The effect of propolis supplementation in improving antioxidant status: A systematic review and meta-analysis of controlled clinical trials

The present study aimed to assess the effect of propolis supplementation on oxidative status, a key contributor to the etiology of many chronic diseases. A systematic search of multiple databases, including Web of Science, SCOPUS, Embase, PubMed, and Google Scholar, was conducted from inception to October 2022 to identify articles examining the effect of propolis on glutathione (GSH), glutathione peroxidase (GPX), total antioxidant capacity (TAC), superoxide dismutase (SOD), and malondialdehyde (MDA) levels. The quality of the included studies was evaluated using the Cochrane Collaboration tool. A total of nine studies were included in the final analysis, and a random-effects model was used to pool the estimated effects. Results showed that propolis supplementation significantly increased the levels of GSH (SMD = 3.16; 95% CI: 1.15, 5.18; I2  = 97.2%), GPX (SMD = 0.56; 95% CI: 0.07, 1.05; p = 0.025; I2  = 62.3%), and TAC (SMD = 3.26; 95% CI: 0.89, 5.62; I2  = 97.8%, p < 0.001). However, the effect of propolis on SOD was not significant (SMD = 0.05; 95% CI: -0.25, 0.34; I2  = 0.0%). Although the MDA concentration was not significantly decreased overall (SMD = -0.85, 95% CI: -1.70, 0.09; I2  = 93.3%), a significant decrease in MDA levels was observed at doses ≥1000 mg/day (SMD = -1.90; 95% CI: -2.97, -0.82; I2  = 86.4) and supplementation durations of less than 11 weeks (SMD = -1.56; 95% CI: -2.60, -0.51; I2  = 90.4). These results suggest that propolis is a safe supplement with a beneficial effect on GSH, GPX, and TAC levels and may be an effective adjunctive therapy for diseases where oxidative stress is a key factor in the etiology. However, further high-quality studies are necessary to make more precise and comprehensive recommendations given the limited number of studies, clinical diversity, and other limitations.

Effect of sesame (Sesamum indicum L.) consumption on glycemic control in patients with type 2 diabetes: A systematic review and meta-analysis of randomized controlled trials

Conflicting evidence exists on the effect of sesame consumption on glucose metabolism in patients with type 2 diabetes (T2D). Therefore, this meta-analysis focuses on the relationship between sesame (Sesamum indicum L.) intervention and glycemic control in patients with T2D. Published literature was retrieved and screened from PubMed, Scopus, ISI Web of Science, and the Cochrane Library up to December 2022. Outcome measures included fasting blood sugar (FBS) concentrations, fasting insulin levels, and hemoglobin A1c (HbA1c) percentage. Pooled effect sizes were reported as weighted mean differences (WMDs) and 95% confidence intervals (CIs). Eight clinical trials (395 participants) were eligible for meta-analyses. Overall, sesame consumption significantly reduced serum FBS (WMD: -28.61 mg/dL, 95% CI: -36.07 to -21.16, p˂0.001; I2  = 98.3%) and HbA1c percentage (WMD: -0.99%, 95% CI: -1.22 to -0.76, p ≤ 0.001; I2  = 65.1%) in patients with T2D. However, sesame consumption did not significantly influence fasting insulin levels (Hedges's: 2.29, 95% CI: -0.06 to 4.63, p = 0.06; I2  = 98.1%). In summary, the current meta-analysis showed a promising effect of sesame consumption on glycemic control through reducing FBS and HbA1c, yet additional prospective studies are recommended, using higher doses and longer intervention period, to confirm the impact of sesame consumption on insulin levels in T2D patients.

Bibliometric analysis on the literature of monk fruit extract and mogrosides as sweeteners

The evolution of research literature on monk fruit extract and mogroside as sweeteners has yet to be investigated. No study has evaluated this literature from a bibliometric perspective. This bibliometric study analyzed the relevant research literature indexed in Web of Science, to unveil its growth and the most productive authors, institutions, countries, journals, and journal categories. In addition, this study aimed to identify the recurring themes of the literature. On July 2023, the Web of Science Core Collection database was accessed with the following search query: TS = (*mogroside* OR "luo han guo" OR "lo han kuo" OR "monk fruit*" OR "monkfruit*" OR "Siraitia grosvenorii") AND TS = (sweet*). The search identified publications mentioning these terms in their title, abstract, or keywords. Only articles and reviews were included. No additional filters were placed on publication year, language, etc. Basic publication and citation frequency counts were recorded directly from the database. The complete record of the publications were exported into VOSviewer and CRExplorer, for visualization of recurring terms and identification of commonly cited references, respectively. The search yielded 155 publications. Publication and citation counts have increased steadily since the 2010s. The most productive authors and institutions were mostly based in Asian countries, such as China, Japan, and Singapore. Nearly half of the publications had contributions from China and were published in journals concerning food science technology. The health effects and biosynthesis of mogrosides were the recurring themes among the top 10 most cited publications. Most of the health effects, such as anti-hyperglycemic, anti-hyperlipidemic, and anti-diabetic properties, were demonstrated in animal models with limited evidence from clinical trials. Future studies should focus on testing in humans. Since monk fruit extracts were generally recognized as safe (GRAS) according to the Food and Drug Administration (FDA), the affirmation of these health benefits in humans by future studies should advocate its use in the food industry and the society to generally improve the public health.

Fruits as nutraceuticals: A review of the main fruits included in nutraceutical patents

Fruits have relevant usefulness in the elaboration of nutraceutical compositions and, as it is considered a "natural medicine", its market has been growing exponentially each year. Fruits, in general, contain a large source of phytochemicals, carbohydrates, vitamins, amino acids, peptides and antioxidants that are of interest to be prepared as nutraceuticals. The biological properties of its nutraceuticals can range from antioxidant, antidiabetic, antihypertensive, anti-Alzheimer, antiproliferative, antimicrobial, antibacterial, anti-inflammatory, among others. Furthermore, the need for innovative extraction methods and products reveals the importance of developing new nutraceutical compositions. This review was developed by searching patents of nutraceuticals from January 2015 until January 2022 in Espacenet, the search database of the European Patent Office (EPO). Of 215 patents related to nutraceuticals, 43% (92 patents) were including fruits, mainly berries. A great number of patents were focused on the treatment of metabolic diseases, representing 45% of the total patents. The principal patent applicant was the United States of America (US), with 52%. The patents were applied by researchers, industries, research centers and institutes. It is important to highlight that from 92 fruit nutraceutical patent applications reviewed, 13 already have their products available on the market.

The efficacy of medicinal plant preparations in the alleviation of radiodermatitis in patients with breast cancer: A systematic review of clinical trials

Radiodermatitis in breast cancer patients varies from mild irritation to life-threatening lesions. Several studies suggest a role for topical corticosteroid ointments in the treatment of radiodermatitis. Yet, to avoid the adverse effects of corticosteroids, many authors recommend the use of topical herbal products instead. The therapeutic role of herbal treatments has yet to be fully understood. This systematic review evaluates the role of topical or oral herbal medicines in radiodermatitis prevention and treatment. A systematic search of four databases (Embase, PubMed, Web of Science, and Scopus) was performed without language and time restrictions from their inception until April 2023. The bibliographies of potential articles were also searched manually. Studies evaluated and compared the effects of herbal preparations with the control group, on dermatitis induced by radiotherapy for breast cancer. The Cochrane risk of bias tool was used to assess the included studies. Thirty-five studies were included in the systematic review. Studies which used herbal drugs including topical and oral formulations were evaluated. Herbal monotherapy and combination therapy were reported, and their effects on radiodermatitis were explained in the systematic review. In conclusion, henna ointments, silymarin gel, and Juango cream were reported to reduce the severity of radiodermatitis. These agents should be considered for radiodermatitis prophylaxis and treatment. The data on aloe gel and calendula ointment were conflicting. Further randomized controlled trials of herbal medications and new herbal formulations are required to determine their effects on breast cancer radiodermatitis.

Cannabidiol and cannabis-inspired terpene blends have acute prosocial effects in the BTBR mouse model of autism spectrum disorder

Introduction

Cannabidiol (CBD) is a non-intoxicating phytocannabinoid with increasing popularity due to its purported therapeutic efficacy for numerous off-label conditions including anxiety and autism spectrum disorder (ASD). Those with ASD are commonly deficient in endogenous cannabinoid signaling and GABAergic tone. CBD has a complex pharmacodynamic profile that includes enhancing GABA and endocannabinoid signaling. Thus, there is mechanistic justification for investigating CBD's potential to improve social interaction and related symptoms in ASD. Recent clinical trials in children with ASD support CBD's beneficial effects in numerous comorbid symptoms, but its impact on social behavior is understudied.

Methods

Here, we tested the prosocial and general anxiolytic efficacy of a commercially available CBD-rich broad spectrum hemp oil delivered by repeated puff vaporization and consumed via passive inhalation in the female cohort of the BTBR strain, a common inbred mouse line for preclinical assessment of ASD-like behaviors.

Results

We observed that CBD enhanced prosocial behaviors using the 3-Chamber Test with a different vapor dose-response relationship between prosocial behavior and anxiety-related behavior on the elevated plus maze. We also identified that inhalation of a vaporized terpene blend from the popular OG Kush cannabis strain increased prosocial behavior independently of CBD and acted together with CBD to promote a robust prosocial effect. We observed similar prosocial effects with two additional cannabis terpene blends from the Do-Si-Dos and Blue Dream strains, and further reveal that these prosocial benefits rely on the combination of multiple terpenes that comprise the blends.

Discussion

Our results illustrate the added benefit of cannabis terpene blends for CBD-based treatment of ASD.

Nutraceuticals and network pharmacology approach for acute kidney injury: A review from the drug discovery aspect

Acute kidney injury (AKI) has become a global health issue, with ~12 million reports yearly, resulting in a persistent increase in morbidity and mortality rates. AKI pathophysiology is multifactorial involving oxidative stress, mitochondrial dysfunction, epigenetic modifications, inflammation, and eventually, cell death. Hence, therapies able to target multiple pathomechanisms can aid in AKI management. To change the drug discovery framework from "one drug, one target" to "multicomponent, multitarget," network pharmacology is evolving as a next-generation research approach. Researchers have used the network pharmacology approach to predict the role of nutraceuticals against different ailments including AKI. Nutraceuticals (herbal products, isolated nutrients, and dietary supplements) belong to the pioneering category of natural products and have shown protective action against AKI. Nutraceuticals have recently drawn attention because of their ability to provide physiological benefits with less toxic effects. This review emphasizes the nutraceuticals that exhibited renoprotection against AKI and can be used either as monotherapy or adjuvant with conventional therapies to boost their effectiveness and lessen the adverse effects. Additionally, the study sheds light on the application of network pharmacology as a cost-effective and time-saving approach for the therapeutic target prediction of nutraceuticals against AKI.

Effect of ginger (Zingiber officinale) intake on human serum lipid profile: Systematic review and meta-analysis

Dyslipidemia is associated with an increased risk of cardiovascular events. Effect of ginger supplementation on lipid profile in humans remains controversial particularly in diabetic patients. A systematic search was performed covering PubMed, Medline, and Scopus, Web of Science (ISI), and Google scholar from January 2010 to January 2022. Inclusion criteria were randomized controlled clinical trials (RCT) study design, at least one of lipid profile components triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL-C), and high-density lipoprotein (HDL-C) measured before and after ginger consumption. For quantitative data synthesis, a random-effects model was applied. Pooled data showed that ginger intake reduced TC (SMD -0.44; 95% CI: -0.86, -0.02; p = 0.025) and TG (SMD -0.61; 95% CI: -1.14, -0.08; p = 0.024) levels significantly, but it has no significant effect on improving HDL-C (SMD 0.40; 95% CI: -0.01, 0.80; p = 0.057) and LDL-C (SMD -0.34; 95% CI: -0.81, 0.13; p = 0.153). Ginger supplementation decreased TG in obese and diabetic subjects more efficiently. In terms of ginger dose, the result of meta-regression found to be significant only for TC, so that increasing daily doses of ginger reduces TC levels by (β: -0.67; 95% CI: -1.28, -0.07; p = 0.028). Therefore, ginger could be considered as an effective lipid lowering nutraceuticals.
