Abstract
Baccharoides anthelmintica (L.) Moench is a popular medicinal plant with a long history of use in several traditional remedies to cure a variety of diseases including; its effect on the central nervous system, gastrointestinal tract, metabolism, kidneys, gynecology, skin diseases, and general health. The present review aims to provide the latest, organized information on toxicological, pharmacological, phytochemical, and ethnomedicinal applications of Baccharoides anthelmintica. For this; several well-known searchable websites (search engines) like; Web of Science, Google Scholar, Scopus-Elsevier, Taylor & Francis, Springer, and DOAJ, were used to empirically investigate the knowledge of this useful medicinal plant. Based on previous studies, the pharmacological action of B. anthelmintica is due to various secondary metabolites including alkaloids, terpenoids, lignans, steroids, and other phytoconstituents. Hence, the present study recorded 225 phytochemicals obtained from different parts of the plant, where the steroids and derivatives (48), terpenes and sesquiterpenes (46), flavonoids and derivatives (41), fatty acids and derivatives (40), phenolic acids (12), triterpenes (11), chalcones (06), diterpenes (01) and miscellaneous (20) were reported. The present review also covered the pharmacological importance, including antioxidant, antimicrobial, antiparasitic, antidiabetic, hypolipidemic action, liver disease, anticancer potential, anti-HIV, antiosteoporotic action, antitoxic action, skin disorder, wound healing and immunomodulatory activity, systemic infection, and treatment of neurodegenerative diseases etc. The review concluded that B. anthelmintica has several pharmacological activities, which were due to the presence of secondary metabolites present in it, and thus indicates the importance of medicinal value of this plant. Hence, B. anthelmintica may be a good source for developing a lead molecule in the process of new drug discovery and development. More study is required to determine the pharmacokinetics, mechanism of action, long-term toxicology testing, safe dosage, and possible interactions with other herbs/drugs.

[PMID: 38754873 PMCID: PMC11097853 DOI: 10.1136/bmjopen-2023-079276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 04/11/2024] [Indexed: 05/18/2024] Open
Abstract
INTRODUCTION Models of care (MoCs) describe evidence-informed healthcare that should be delivered to patients. Several MoCs have been implemented for low back pain (LBP) to reduce evidence-to-practice gaps and increase the effectiveness and sustainability of healthcare services. OBJECTIVE To synthesise research evidence regarding core characteristics and key common elements of MoCs implemented in primary healthcare for the management of LBP. DESIGN Scoping review. DATA SOURCES Searches on MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, PEDro, Scopus, Web of Science and grey literature databases were conducted. ELIGIBILITY CRITERIA Eligible records included MoCs implemented for adult LBP patients in primary healthcare settings. DATA EXTRACTION AND SYNTHESIS Data extraction was carried out independently by two researchers and included a summary of the studies, the identification of the MoCs and respective key elements, concerning levels of care, settings, health professionals involved, type of care delivered and core components of the interventions. Findings were investigated through a descriptive qualitative content analysis using a deductive approach. RESULTS 29 studies reporting 11 MoCs were included. All MoCs were implemented in high-income countries and had clear objectives. Ten MoCs included a stratified care approach. The assessment of LBP patients typically occurred in primary healthcare while care delivery usually took place in community-based settings or outpatient clinics. Care provided by general practitioners and physiotherapists was reported in all MoCs. Education (n=10) and exercise (n=9) were the most common health interventions. However, intervention content, follow-ups and discharge criteria were not fully reported. CONCLUSIONS This study examines the features of MoCs for LBP, highlighting that research is in its early stages and stressing the need for better reporting to fill gaps in care delivery and implementation. This knowledge is crucial for researchers, clinicians and decision-makers in assessing the applicability and transferability of MoCs to primary healthcare settings.

[PMID: 38798299 PMCID: PMC11111726 DOI: 10.14202/vetworld.2024.785-795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Accepted: 03/18/2024] [Indexed: 05/29/2024] Open
Abstract
Background and Aim Stingless bees are generally found in tropical countries, including Indonesia. In West Sumatra, stingless bees are known as Galo-galo, consist of several species with different characteristics; however, the properties of honey produced by stingless bees have not yet been explored. This study aimed to determine the physicochemical, antioxidant, and antimicrobial activities as well as the microbiota profile of stingless bee honey from the bee species Heterotrigona itama, Geniotrigona thoracica, Tetrigona melanoleuca, and Tetrigona binghami that are intensively developed in West Sumatra, Indonesia. Materials and Methods Honey produced by the stingless bee species H. itama, G. thoracica, T. melanoleuca, and T. binghami originating in West Sumatra was examined in the present study. The physicochemical properties (Association of Official Analytical Chemists), antioxidant activity (2,2-diphenyl-1-picrylhydrazyl technique), total phenols (Folin-Ciocalteu method), antimicrobial activity (Agar-Well diffusion test), total lactic acid bacteria, and microbiota diversity were measured in stingless bee honey samples. Results Stingless bee species significantly affected the physicochemical properties, antioxidant activity, total phenolic content, antimicrobial activity, and total lactic acid bacteria (p = 0.05), except for the crude fiber content. The carbohydrate profiles of honey produced by H. itama and T. binghami were dominated by monosaccharides, whereas those of honey from T. melanoleuca and G. thoracica were dominated by disaccharides. In terms of antioxidant activity (half maximal inhibitory concentration [IC50] value), there were no significant differences (p > 0.05) between honey from H. itama, T. melanoleuca, and T. binghami, but there were significant differences (p > 0.05) between honey from G. thoracica. The honey of G. thoracica and T. melanoleuca had the highest total phenolic content (65.65 ± 14.00 and 69.78 ± 8.06, respectively). In addition, honey from the four stingless bee species showed antimicrobial activity against the pathogenic bacteria Escherichia coli, Salmonella, Staphylococcus aureus, and Listeria monocytogenes. From the principal co-ordinate analysis (PCoA) results, it can be concluded that the microbiota profiles of the four stingless bee honey samples differed. Conclusion The results showed that honey from H. itama, G. thoracica, T. melanoleuca, and T. binghami has different physicochemical characteristics, antioxidant activity, antimicrobial activity, and microbiota diversity. By knowing the content of this stingless bee honey, the results of this study can be used as information that this stingless bee honey has the potential as a functional food that is beneficial for health.

Abstract
OBJECTIVE This study was aimed at assessing the prevalence of herbal drug use among pregnant women with access to modern medicine and associated factors in public health facilities in the west Shewa zone, Oromia regional state, Ethiopia. DESIGN A sequential mixed-method study approach was carried out among pregnant women and other stakeholders. SETTING This study was conducted at public health facilities, including 3 public hospitals and 20 health centres, in the west Shewa zone of Ethiopia. PARTICIPANTS A systematically selected sample of 411 pregnant women was participated in the quantitative study. For the qualitative method, focus group discussions and in-depth interviews were conducted among pregnant women attending antenatal care and key informants using an interview guide until data saturation was achieved. PRIMARY OUTCOME For outcome variables, the respondents were asked if they used any herbal medicine during their current pregnancy. It was then recorded as 0=no and 1=yes. RESULTS The prevalence of herbal medicines was found to be 19.7%. The most commonly used herbal medicines were Zingiber officinale, Ocimum gratissimum, Eucalyptus globules, Allium sativum and Rutacha lepensis. Herbal medicine use during pregnancy was significantly associated with older maternal age (adjusted OR (AOR) 2.4, 95% CI 1.2 to 5.1), urban residence (AOR 2.3, 95% CI 1.3 to 3.7) and second trimester of pregnancy (AOR 2.3, 95% CI 1.3 to 4.5). CONCLUSIONS In this study, one in five pregnant women uses herbal medicine, which is relatively low. Sociodemographic factors and the duration of pregnancy affected the utilisation of herbal drugs during pregnancy. The most common herbals used by pregnant women were intended to treat minor disorders of pregnancy and medical disorders such as hypertension.

Abstract
Background Acute lung injury (ALI) is a severe condition distinguished by inflammation and impaired gas exchange in the lungs. Staphylococcus aureus, a common bacterium, can cause ALI through its virulence factors. Aloe vera is a medicinal plant that has been traditionally used to treat a variety of illnesses due to its anti-inflammatory properties. Chitosan nanoparticles are biocompatible and totally biodegradable materials that have shown potential in drug delivery systems. Aim To explore the antibacterial activity of Aloe vera-loaded chitosan nanoparticles (AV-CS-NPs) against S. aureus in vitro and in vivo with advanced techniques. Methods The antibacterial efficacy of AV-CS-NPs was evaluated through a broth microdilution assay. In addition, the impact of AV-CS-NPs on S. aureus-induced ALI in rats was examined by analyzing the expression of genes linked to inflammation, oxidative stress, and apoptosis. Furthermore, rat lung tissue was scanned histologically. The rats were divided into three groups: control, ALI, and treatment with AV-CS-NPs. Results The AV-CS-NPs that were prepared exhibited clustered semispherical and spherical forms, having an average particle size of approximately 60 nm. These nanoparticles displayed a diverse structure with an uneven distribution of particle sizes. The maximum entrapment efficiency of 95.5% ± 1.25% was achieved. The obtained findings revealed that The minimum inhibitory concentration and minimum bactericidal concentration values were determined to be 5 and 10 ug/ml, respectively, indicating the potent bactericidal effect of the NPs. Also, S. aureus infected rats explored upregulation in the mRNA expression of TLR2 and TLR4 compared to healthy control groups. AV-CS-NP treatment reverses the case where there was repression in mRNA expression of TLR2 and TLR4 compared to S. aureus-treated rats. Conclusion These NPs can serve as potential candidates for the development of alternative antimicrobial agents.

Abstract
Diabetes increases the production of free radicals and inflammatory agents in the heart tissue and alters the expression of genes associated with the induction of apoptosis. Considering the importance of common cardiovascular disorders in diabetes, this study investigated the effect of eight weeks of aerobic exercise and crocin use, as well as tissue damage and oxidative stress caused by diabetes in the hearts of adult rats. Streptozotocin 50 mg/kg was injected as a single dose intraperitoneally to cause the diabetes. After 72 hours, a glucometer monitored blood glucose levels, and blood glucose above 250 mg/dl was considered diabetes. Continuous treadmill exercise was performed for eight weeks by placing the animal on the treadmill. Next, the animals were anesthetized, and samples were taken from the hearts and frozen in liquid nitrogen. Then, superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA) were measured in the cardiac tissue. Finally, the hearts of half of the animals were immediately immersed in a formalin solution for histological changes. According to our findings, diabetes increased lipid peroxidation, characterized by increased MDA levels in the control diabetes group and decreased SOD and GPx levels (P <0.05). It also changes the balance of expression of genes associated with apoptosis control, increased Bcl-2-associated X (Bax) expression, and decreased Bcl-2 expression (P <0.05). Also, we observed the induction of apoptosis in cardiac tissue. Using eight weeks of continuous exercise and administration of crocin significantly reduced blood sugar levels and lipid peroxidation and increased the activity of antioxidant enzymes and Bcl-2 gene expression compared to the diabetes control group. In addition, continuous exercise and crocin improved the oxidative stress parameters in the control group. This study showed that diabetes could cause oxidative stress and heart dysfunction. Moreover, simultaneously and separately, aerobic exercise with a treadmill and crocin administration can reduce these disorders and prevent apoptosis in the heart tissue.

BMC Complement Med Ther 2023; 23:451. [PMID: 38087333 PMCID: PMC10717688 DOI: 10.1186/s12906-023-04270-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 11/21/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Traditional medicine (TM) plays a key role in maintaining health in many societies. Given the requirement for TM disclosure, Allopathic Medicine Practitioners (AMPs) must encourage open communication with patients to persuade those who use TM to disclose. Addressing patient non-disclosure of TM requires this dialogue to be facilitated. We sought to understand and describe how South African AMPs facilitate disclosure of TM use during a consultation with patients who use both TM and allopathic medicine (AM) and how it influences the patients' willingness to disclose TM use. METHODS This qualitative exploratory descriptive study on AMPs at Gauteng district public hospitals in South Africa was conducted between 2021 and 2022. Non-probability purposive sampling was employed to select a sample of 14 AMPs. Individual participants were encouraged to share their unique experiences and interpretations of the phenomenon concerning TM use disclosure. The raw transcribed textual data were processed using ATLAS.ti, and inductive content analysis was undertaken following the coding of the content to identify categories. RESULTS The data revealed four major categories: 'providing a suitable atmosphere for disclosure,' 'encouraging patients to disclose TM usage to AMPs,' 'patient autonomy,' and 'AMP training'. During a consultation with patients who use both TM and AM, participants expressed their experiences and perceptions of TM nondisclosure. They also discussed several methods for encouraging patients to disclose their TM usage, particularly when TM is used concurrently with AM. CONCLUSION This study expands on previously reported findings by describing how South African AMPs facilitate the disclosure of TM use during consultation. Many AMPs struggle to initiate TM conversations with their patients which results in non-disclosure. This study revealed that integrating TM into AM training programmes, promoting cross-practice, and creating a safe environment is necessary for the development and application of the most appropriate approaches that would assist in facilitating disclosure.

Abstract
Diabetes is a metabolic disorder owing to the insulin faulty production or the resistance to the action mechanism where the accumulation of glucose is the major side effect in the body in the case of diabetes. Numerous herbs with the potential of reducing glucose production along with combating the secondary ailments associated with it but >1% out of 250,000 have been pharmacologically validated. Affordability and historical usage of these herbal remedies often result in patients' preference as primary or as adjunctive to conventional therapies. Clinical trials conducted with herbs are necessary for determining the efficacy of the herbs against diabetes. Additional benefits of herbal employment include the treatment of secondary ailments in patients along with diabetes including triglyceride reduction, cholesterol level management, body mass index, and cardiovascular disease control. Any individual extract marketed as antidiabetic formulations requires clinical validation before adoption but with ongoing disease status, quick validation in protocols and testing is needed to understand, isolate and cross-verify the status of the bioactive ingredient in individual herb and the polyherb extract formulations. Standardization, characterization, long-term role and impact on the human body, efficacy status, and toxicity profile need to be addressed fully for each active ingredient before it is advanced for production. Therefore, after trials, the related regulatory bodies will be approached to confirm the safety status and efficacy of the prepared concoction.

Abstract
Diabetic nephropathy (DN) is a worldwide issue that eventually leads to end-stage renal failure, with limited therapeutic options. Prior research has revealed that gold nanoparticles (AuNPs) have a substantial antidiabetic impact. In addition, sodium-glucose cotransporter2 (SGLT2) inhibitors, including dapagliflozin (DAPA), had renoprotective impact on DN. Therefore, this research attempted to determine the potential AuNPs and DAPA impacts in ameliorating experimentally DN induction and the underlying mechanisms focusing on miR-192 and miR-21, correlating them with autophagy, apoptosis, fibrosis, and oxidative stress. Diabetes induction was through a single intraperitoneal streptozotocin (55 mg/kg) injection, and rats with diabetes received AuNPs (2.5 mg/kg/day) as well as DAPA (2 mg/kg/day) for 7 weeks as a treatment. AuNPs and DAPA treatment for 7 weeks substantially alleviated DN. AuNPs and DAPA significantly increased catalase (CAT) activity as well as serum total antioxidant capacity (TAC), along with a substantial decline in malondialdehyde (MDA). AuNPs and DAPA treatment alleviated renal fibrosis as they decreased transforming growth factorß1(TGF-ß1) as well as matrix metalloproteinase-2 (MMP-2) renal expression, decreased apoptosis through alleviating the proapoptotic gene (caspase-3) renal expression and increased the antiapoptotic gene (Bcl-2) renal expression, and increased autophagy as they increased LC-3 as well as Beclin-1 renal expression. Autophagy activation, inhibition of apoptosis, and renal fibrosis could be due to their inhibitory impact on miR-192 and miR-21 renal expression. AuNPs and DAPA have a protective effect on DN in rats by targeting miR-192 and miR-21 and their downstream pathways, including fibrosis, apoptosis, autophagy, and oxidative stress.

Abstract
Work-related Musculoskeletal Disorders can cause neck and shoulder pain in office workers. The research objective was to investigate the efficacy of Ruesi Dadton exercise (RD) and Yoga exercise (YE) compared with Stretching exercise (SE) on reducing neck and shoulder pain in office workers. A single-blind randomized controlled trial was conducted at Thai Traditional Health Promotion Center, Thai Traditional and Alternative Medicine Hospital. A total number of 80 participants, equally divided into three groups: two intervention groups of RD (n=26), YE (n=28), and a control group of stretching exercise (SE) (n=26) who completed the 4-week intervention program. The primary outcomes were pain relief assessed by Visual Analog Scale, Pressure Pain Threshold, muscle flexibility by Cervical Range of Motion. The secondary outcome was World Health Organization's Quality of Life test. ANOVA, paired t-tests and repeated ANOVA were used to analyze the data. The results showed that the comparison of all three groups before and after the exercises revealed a decrease in pain, better tolerance to pain and more flexibility of the neck muscles with statistical significance (p< 0.05). With respect to the quality of World Health Organization's Quality of Life, the comparison of all four domains in all three groups before and after the exercises indicated a statistically significant improvement in quality of life (p< 0.05). However, there were no differences in pain, neck muscle flexibility and quality of life between groups.

Tesfaye O. Evaluating the Antioxidant Properties of Unifloral Honey ( Apis mellifera L.) from Ethiopia. INTERNATIONAL JOURNAL OF FOOD SCIENCE 2023; 2023:7664957. [PMID: 37484116 PMCID: PMC10362986 DOI: 10.1155/2023/7664957] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 06/01/2023] [Accepted: 06/28/2023] [Indexed: 07/25/2023]
Abstract
The antioxidant properties of natural honey primarily rely on the floral origin from which nectar is collected by bees. Thus, the current activity evaluated the antioxidant properties of honey based on its floral type. The honey floral origin was verified by the melissopalynological technique. Antioxidant properties were determined by using standard procedures and analyzed by SAS. Six unifloral honey types with their harvesting month were identified. Accordingly, Guizotia (74% of pollen frequency), Coffea arabica (68%), Vernonia (90%), Croton macrostachyus (64%), Schefflera abyssinica (100%), and Eucalyptus (100%) were cropped in November, February, February, May, April, and June separately. Statistically, a variation (p < 0.05) in antioxidant parameters was displayed between unifloral honeys. Vernonia honey exhibited the maximum total phenol (77.2 ± 0.7), total flavonoid (65.0 ± 3.8), and total antioxidant content (65.4 ± 0.3). On the other hand, S. abyssinica honey recorded the least total phenol content (24.1 ± 0.4), total flavonoid content (18.6 ± 2.7), and total antioxidant content (5.6 ± 0.5). Statistical analysis showed a positive correlation between all the tested antioxidant parameters. Thus, the current study indicated that all the tested Ethiopian unifloral honey had good sources of antioxidants with the most Vernonia honey followed by C. macrostachyus whereas S. abyssinica honey had the least followed by Eucalyptus.

Abstract
In this work, the extract of cinnamon bark was used for the green synthesis of cinnamon-Ag nanoparticles (CNPs) and other cinnamon samples, including ethanolic (EE) and aqueous (CE) extracts, chloroform (CF), ethyl acetate (EF), and methanol (MF) fractions. The polyphenol (PC) and flavonoid (FC) contents in all the cinnamon samples were determined. The synthesized CNPs were tested for the antioxidant activity (as DPPH radical scavenging percentage) in Bj-1 normal cells and HepG-2 cancer cells. Several antioxidant enzymes, including biomarkers, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST), and reduced glutathione (GSH), were verified for their effects on the viability and cytotoxicity of normal and cancer cells. The anti-cancer activity depended on apoptosis marker protein levels (Caspase3, P53, Bax, and Pcl2) in normal and cancerous cells. The obtained data showed higher PC and FC contents in CE samples, while CF showed the lowest levels. The IC50 values of all investigated samples were higher, while their antioxidant activities were lower than those of vitamin C (5.4 g/mL). The CNPs showed lower IC50 value (55.6 µg/mL), whereas the antioxidant activity inside or outside the Bj-1 or HepG-2 was found to be higher compared with other samples. All samples execrated a dose-dependent cytotoxicity by decreasing the cells' viability percent of Bj-1 and HepG-2. Similarly, the anti-proliferative potency of CNPs on Bj-1 or HepG-2 at different concentrations was more effective than that of other samples. Higher concentrations of the CNPs (16 g/mL) showed greater cell death in Bj-1 (25.68%) and HepG-2 (29.49%), indicating powerful anti-cancer properties of the nanomaterials. After 48 h of CNPs treatment, both Bj-1 and HepG-2 showed significant increases in biomarker enzyme activities and reduced glutathione compared with other treated samples or untreated controls (p < 0.05). The anti-cancer biomarker activities of Caspas-3, P53, Bax, and Bcl-2 levels were significantly changed in Bj-1 or HepG-2 cells. The cinnamon samples were significantly increased in Caspase-3, Bax, and P53, while there were decreased Bcl-2 levels compared with control.

Abstract
OBJECTIVES Despite the paucity of evidence verifying its efficacy and safety, traditional Chinese medicine (TCM) is expanding in popularity and political support. Decisions to include TCM diagnoses in the International Classification of Diseases 11th Revision and campaigns to integrate TCM into national healthcare systems have occurred while public perception and usage of TCM, especially in Europe, remains undetermined. Accordingly, this study investigates TCM's popularity, usage and perceived scientific support, as well as its relationship to homeopathy and vaccinations. DESIGN/SETTING We performed a cross-sectional survey of the Austrian population. Participants were either recruited on the street (in-person) or online (web-link) via a popular Austrian newspaper. PARTICIPANTS 1382 individuals completed our survey. The sample was poststratified according to data derived from Austria's Federal Statistical Office. OUTCOME MEASURES Associations between sociodemographic factors, opinion towards TCM and usage of complementary medicine (CAM) were investigated using a Bayesian graphical model. RESULTS Within our poststratified sample, TCM was broadly known (89.9% of women, 90.6% of men), with 58.9% of women and 39.5% of men using TCM between 2016 and 2019. Moreover, 66.4% of women and 49.7% of men agreed with TCM being supported by science. We found a positive relationship between perceived scientific support for TCM and trust in TCM-certified medical doctors (ρ=0.59, 95% CI 0.46 to 0.73). Moreover, perceived scientific support for TCM was negatively correlated with proclivity to get vaccinated (ρ=-0.26, 95% CI -0.43 to -0.08). Additionally, our network model yielded associations between TCM-related, homeopathy-related and vaccination-related variables. CONCLUSIONS TCM is widely known within the Austrian general population and used by a substantial proportion. However, a disparity exists between the commonly held public perception that TCM is scientific and findings from evidence-based studies. Emphasis should be placed on supporting the distribution of unbiased, science-driven information.

Abstract
Background and Purpose Dermatophytosis is one of the most prevalent zoonotic diseases. Increased resistance of dermatophytosis-causing pathogens against antidermatophytic agents highlights the need for alternative medicine with higher efficiency and lower side effects. In the present study, the in vitro antifungal activities of different concentrations of Gracilaria corticata methanol extract against Trichophyton mentagrophytes, Microsporum canis, and Microsporum gypseum were assessed and their efficacy was evaluated in rat dermatophytosis models. Materials and Methods The broth microdilution and well diffusion methods were used to determine the in vitro antidermatophytic activity. The in vivo study was carried out using 40 dermatophytosis-infected adults male Wistar rats. The animals were divided into 4 groups (5% and 10% G. corticata ointment, terbinafine, and Vaseline) and treated with ointment until complete recovery. The percentage of wound closure was calculated for each group. Results The results revealed that G. corticata methanol extract was effective to varying extents against the tested dermatophytes. The highest inhibitory activity of G. corticata was found against T. mentagrophytes with minimum inhibitory concentration and minimum fungicidal concentration values of 4 and 9 µg mL-1, respectively. The in vivo experiment revealed that 10% G. corticata ointment significantly accelerated skin lesions reduction and completely cured M. gypseum, T. mentagrophytes, and M. canis infections after 19, 25, and 38 days, respectively. Conclusion The methanol extract of G. corticata exhibited significant antifungal activity in vitro and in vivo, suggesting that it could be used as an alternative to antidermatophytic therapy in a dose-dependent manner.

Abstract
BACKGROUND The disruptions in skin integrity contribute to its disorientation, and tissue annihilations result in acute or chronic wound formation. Polyherbal formulations are widely used in traditional systems of mecdicine like ayurveda for wound healing. The combination of these traditional therapies with clinical therapies has helped in the development of various wound-healing products. METHOD In this systematic review, the therapeutic potency of several polyherbal formulations from different medicinal floras is summed together in response to their impact on wound healing. The literature search was performed on Pubmed, Scopus, and ScienceDirect databases between 2010-2020. PRISMA methodology was applied to extract relevant information about polyherbal formulations. RESULT A total of 54 articles were selected under all themes for the data extraction as per the PRISMA guidelines. These 54 articles have high-quality scores ≥3. Forty-three records were used for the narrative analysis, while nine records were used for the critical analysis in the narrative review. Further, theme-wise key data sets were screened from the selected literature and summarized in a tabular form. Bibliometric analysis of the Scopus database has also drawn attention to limited academic literature showcasing randomized clinical trials in the current subject. Most of these polyherbal formulations are tested in laboratory-scale studies, thus portraying further research options. CONCLUSION Polyherbal formulations are effective in promoting the wound-healing process. They can stimulate a variety of physiological functions that accelerates the process of healing. These formulations merit further investigation in clinical trials, and production up scaling will aid in the creation of a new horizon of polyherbal wound healing products.

Abstract
Amyotrophic lateral sclerosis" (ALS) is a progressive neuronal disorder that affects sensory neurons in the brain and spinal cord, causing loss of muscle control. Moreover, additional neuronal subgroups as well as glial cells such as microglia, astrocytes, and oligodendrocytes are also thought to play a role in the aetiology. The disease affects upper motor neurons and lowers motor neurons and leads to that either lead to muscle weakness and wasting in the arms, legs, trunk and periventricular area. Oxidative stress, excitotoxicity, programmed cell death, altered neurofilament activity, anomalies in neurotransmission, abnormal protein processing and deterioration, increased inflammation, and mitochondrial dysfunction may all play a role in the progression of ALS. There are presently hardly FDA-approved drugs used to treat ALS, and they are only beneficial in slowing the progression of the disease and enhancing functions in certain individuals with ALS, not really in curing or preventing the illness. These days, researchers focus on understanding the pathogenesis of the disease by targeting several mechanisms aiming to develop successful treatments for ALS. This review discusses the epidemiology, risk factors, diagnosis, clinical features, pathophysiology, and disease management. The compilation focuses on alternative methods for the management of symptoms of ALS with nutraceuticals and phytotherapeutics.

Abstract
Objectives Several lines of research have shown that hepatic fibrosis is one of the leading causes of death worldwide. Trans-chalcone is a flavonoid precursor with anti-oxidant and anti-inflammatory effects. The present study was conducted to examine the antifibrotic properties of trans-chalcone on bile duct ligation (BDL)-induced liver cholestasis in rats. Materials and Methods Following the BDL operation, trans-chalcone at doses of 12, 24, and 50 mg/kg was administered orally once a day for 45 consecutive days. Serum levels of liver indices, including alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total and direct bilirubin, and lipid profile in addition to blood urea nitrogen (BUN) and creatinine, were measured. Additionally, catalase (CAT) and superoxide dismutase (SOD) activities were assessed in liver homogenates. Histopathological evaluations were performed using Masson trichrome (MT) and hematoxylin and eosin (H&E) staining. Results The elevated levels of liver enzymes, total and direct bilirubin, BUN, creatinine, cholesterol, triglyceride, and low-density lipoprotein (LDL) induced by BDL were significantly reduced following trans-chalcone administration; while serum level of high-density lipoprotein (HDL) increased. Besides, treatment with trans-chalcone elevated the activities of CAT and SOD in the liver tissues of the animals with BDL surgery. According to MT and H&E staining, BDL-induced histopathological changes, including infiltration of inflammatory cells, hepatocyte necrosis, ductal hyperplasia, and collagen deposition were ameliorated using trans-chalcone administration. Conclusion It can be concluded from the present study that trans-chalcone, possibly by its anti-oxidant and anti-inflammatory properties, may exert hepatoprotective and antifibrotic effects in BDL-induced liver fibrosis.

Abstract
Background Hyperglycemia conditions in diabetes mellitus (DM) can turn on pro-inflammatory cytokines like IL-6 and TNF-α. These cytokines play a role in insulin resistance and the development of DM complications. People in Indonesia have used Phaleria macrocarpa to treat diabetes, but the leaf of this plant has not been studied to see if it can reduce inflammation. Objective This study aims to analyze the effect of ethanolic extract of Phaleria macrocarpa leaves (EEPML) in serum IL-6 and TNF-α levels of diabetic rats. Methods This study was an experiment with a post-test-only control group design. Thirty 8-week-old male Wistar rats were used in the study. They were split into six groups: K1 was the normal control group; K2 was the DM control group; K3, K4, and K5 were given EEPML at doses of 125, 250, and 500 mg/KgBW; and K6 was given metformin 45 mg/KgBW orally once a day for 14 days. A high-fat diet and a 30 mg/KgBWi.p injection of streptozotocin were used to make the diabetic rat model. ELISA method for measuring serum IL-6 and TNF-α levels. The Kruskal-Wallis and the Mann-Whitney test were used to examine the differences between the groups. Results There were significant differences between treatment groups in the mean levels of serum IL-6 (p=0.017), but there were no significant differences in the mean levels of serum TNF-α (p>0.05). Conclusion Administration of Phaleria macrocarpa leaf ethanol extract 125 mg/KgBW reduced serum IL-6 levels but could not significantly reduce serum TNF-α levels in diabetic rats.

Abstract
A new juvenile hormone III, canangalia I (1), along with six known juvenile hormone III analogues (2-7), was isolated from the methanolic extract of Cananga latifolia stems. All structures were elucidated using spectroscopic data and compared with data from previous literature. Canangalia I (1) was found to be cytotoxic against human cervical adenocarcinoma (HeLa) cells with an IC50 value of 35.00 ± 2.15 µg/ml after 72 h, but was not toxic to Vero cells.

Abstract
Investigation of the leaves of Bauhinia thonningii Schum led to the isolation and identification of a new flavonol derivative, 6-C-methylquercetin-3,4'-dimethyl ether (1) together with eleven known compounds (2-13), with two of them (10 and 11) obtained as a mixture. Their structures were established by extensive spectroscopic analyses. Antibacterial activity of compound 1 as well as the reference antibiotic, ciprofloxacin was tested on Gram-negative multidrug-resistant bacteria overexpressing active efflux pumps, and against methicillin-resistant strains of Staphylococcus aureus (MRSA). Samples were tested alone and in combination with an efflux pump inhibitor (EPI), phenylalanine-arginine-β-naphthylamide (PAßN). Results show that when compound 1 was tested alone, its inhibitory effects were obtained on 7/10 tested bacteria with the highest MIC value of 128 µg/mL whilst in the presence of EPI, this activity significantly increase in all the 10 bacteria. An interesting antibacterial activity was obtained with compound 1 against Klebsiella pneumoniae ATCC11296 (MIC of 4 µg/mL), KP55 and Staphylococcus aureus MRSA6 in the presence of the PaßN.

Abstract
Type-1 Diabetes Mellitus (T1DM) is regarded as a multifunctional, immune-related disease which causes massive destruction of islet β-cells in pancreas resulting in hyperglycemic, hypoinsulinemia and hyperlipidimic conditions. The aim of the present study, was to investigate the hypothesis that streptozotocin (STZ)-induced T1DM in Balb/c mice when treated with crude polysaccharide from seaweed, Dictyopteris divaricata (CDDP) depicts improvement in diabetes-related symptoms. Treatment with CDDP resulted in decreased body weight loss, improved food consumption and water intake disbalances. The CDDP effectively improved fasting blood glucose, oral glucose tolerance (OGTT), serum insulin, insulin secretion, rejuvenation of β-cells mass, serum lipid profile and pro-inflammatory cytokines levels. Additionally, treatment with CDDP increased the population of beneficial bacteria such as Firmicutes, Bacteroidetes and Lactobacillus at phylum, family and genus levels by 16S rRNA sequencing. Furthermore, immunohistological examination confirmed that CDDP reduces the inflammation and restored the structural morphology of colon and upraised the levels of insulin receptor substrate-1 (IRS-1), Mucin-2 (MUC-2) and tight-junction proteins (TJs) whereby maintaining the gut structures and barrier permeability. Thus, the above presented data, highlights the safe and therapeutic effects of crude polysaccharide (CDDP) from D. divaricata in the treatment and restoration of T1DM disorders and can be used as a food supplement alternative to diabetes medicine.

Abstract
Recently, an interest has surged in utilizing indigenous medicinal plants to treat infectious illnesses and extract bioactive substances, highlighting the need to analyze medicinal plants for phytochemicals and bioactivities. The present study was aimed to evaluate the impact of different solvent systems (aqueous, ethanol, and methanol) used for extraction on total phenolics, total flavonoids, antioxidant, and antibacterial activity of three medicinal plants of Azad Kashmir (Achillea millefolium, Bergenia ciliata, and Aloe vera). High phenolic content was found in methanol extracts of B. ciliata (27.48 ± 0.58 mg GAE/g dry weight), A. vera (25.61 ± 0.33 mg GAE/g dry weight), and A. millefolium (24.25 ± 0.67 mg GAE/g dry weight). High flavonoid content was obtained in the ethanol extract of A. millefolium (27.13 ± 0.64 mg QE/g dry weight), methanol extract of B. ciliata (17.44 ± 0.44 ± 0.44 mg QE/g dry weight), and the methanol extract of A. vera (14.68 ± 0.67 mg QE/g dry weight). Strong 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH) was obtained with a methanol extract of B. ciliata (IC50 = 60.27 ± 0.20 µg/mL). With a zone of inhibition and a minimum inhibitory concentration ranging from 10.00 ± 0.66 to 24.67 ± 1.21 mm and 78 to 625 µg/mL, respectively, all of the studied plants demonstrated notable antibacterial activity against Staphylococcus aureus and Escherichia coli. A. vera showed greater antibacterial activity as compared to other plants under study while methanolic extract showed greater antibacterial activity than ethanolic and aqueous extract. The findings of this research support the use of these medicinal plants to treat a variety of diseases.

Abstract
OBJECTIVES Pharmacists are ideal partners for engaging with the needs and expectations of patients. They can play a vital role by providing information and supplying herbal medicines. In some community settings, pharmacists are also the main first point of care. This study explored Jordanian community pharmacists' perspectives and knowledge of herbal medicines available in pharmacies. DESIGN A cross-sectional study using an online survey was developed, and it was distributed via social media platforms. The one-way analysis of variance (ANOVA) test was used to compare the mean knowledge scores between different demographic groups. Multiple linear regression analysis was used to identify predictors of herbal medicines knowledge. SETTING Jordanian community pharmacies. PARTICIPANTS 401 Jordanian community pharmacists. RESULTS Herbal supplements are sold in practically all pharmacies (98.5%). Slimming aids (14.7%), followed by sexual and sports enhancements (14%) and maintaining general health (12.1%) were most requested by Jordanian customers. While supplements for maintaining general health (12%), followed by slimming aids (11.4%) and skin conditions (9.3%) were most recommended by Jordanian pharmacists. 63.1% were not aware of potential herb-drug interactions, 95.6% did not receive complaints from customers about herbal medicines and 41.2% would not report adverse reactions to the national pharmacovigilance services. The mean knowledge score for knowledge of use, regulation, adverse reactions, and drug interactions was 3.7 (SD: 0.7), 3.5 (SD: 0.8), 3.6 (SD: 0.8), and 3.6 (SD: 0.8) (out of 5), respectively. ANOVA test showed that total pharmacists' knowledge scores significantly differed based on the length of time practising pharmacy (p<0.05). CONCLUSION This study highlights some key concerns relating to recommendations, awareness and reporting of herbal medicines among Jordanian community pharmacists. Pharmacists need enhanced education to provide objective and evidence-based information on the benefits-risks of herbal medicines. Future studies need to be carried out to confirm whether our findings are transferable to other Middle Eastern countries.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 293:115245. [PMID: 35367330 DOI: 10.1016/j.jep.2022.115245] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 03/12/2022] [Accepted: 03/27/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peptic ulcer disease (PUD) ranks top among the most prominent gastrointestinal problems prevalent around the world. Long-term use of non-steroidal anti-inflammatory drugs, pathogenic infection by Helicobacter pylori, imbalances between gastrointestinal regulatory factors and pathological hyperacidity are major contributors towards the development of peptic ulcers. Although synthetic drugs of multiple pharmacological classes are abundantly available, inadequacy of such agents in ensuring complete recovery in not uncommon. Therefore, pharmacological explorations of herbal products including plant extracts and their respective isolated phytoconstituents, for potential gastroprotective and antiulcer properties, are regular practice among the scientific community. Moreover, the historical preferences of a significant share of world population towards herbal-based medication over modern synthetic drugs also contribute significantly to such endeavors. AIM OF THE REVIEW This review has endeavored to present ethnomedicinal and pharmacological prospects of a significant number of authenticated plant species in terms of their capacity to exert gastroprotection and antiulcer activities both in vitro and in vivo. The information delineated along the way was further subjected to critical analysis to ascertain the possible future prospects of such findings into designing plant-derived products in future for the treatment of peptic ulcer. MATERIALS AND METHODS Electronic version of prominent bibliographic databases, including Google Scholar, PubMed, Scopus, ScienceDirect, Wiley Online Library, SpringerLink, Web of Science, and MEDLINE were explored extensively for the identification and compilation of relevant information. The plant names and respective family names were verified through the Plant List (version 1.1) and World Flora Online 2021. All relevant chemical structures were verified through PubChem and SciFinder databases and illustrated with ChemDraw Ultra 12.0. RESULTS A colossal number of 97 plant species categorized under 58 diverse plant families have been discussed in the review for their gastroprotective and antiulcer properties. In vivo illustrations of the pharmacological properties were achieved for almost all the species under consideration. 29 individual phytoconstituents from these sources were also characterized with similar pharmacological potentials. Majority of the plant extracts as well as their constituents were found to exert their gastroprotective effects through antioxidative pathway featuring both enzymatic and nonenzymatic mechanism. Moreover, active inhibition of acid secretion, upregulation of gastroprotective mediators and downregulation of pro-inflammatory cytokines, were also associated with a prominent number of plants or products thereof. CONCLUSIONS Comparative evaluations of the plant sources for their antiulcer activities, both as individual and as combination formulations, are necessary to be conducted in human subjects under properly regulated clinical conditions. Moreover, the efficacy and safety of such products should also be evaluated against those of the currently available treatment options. This will further facilitate in ascertaining their suitability and superiority, if any, in the treatment of peptic ulcer diseases. Implementation of these endeavors may eventually lead to development of more efficient treatment options in the future.

Abstract
Background Use of traditional medicine (TM) is widespread in sub-Saharan Africa as a treatment option for a wide range of disease. We aimed to describe main characteristics of TM users and estimate the association of TM use with control of hypertension. Methods We used data on 2128 hypertensive patients of a cross-sectional study (convenience sampling), who attended cardiology departments of 12 sub-Saharan African countries (Benin, Cameroon, Congo, Democratic Republic of the Congo, Gabon, Guinea, Côte d’Ivoire, Mauritania, Mozambique, Niger, Senegal, Togo). To model association of TM use with odds of uncontrolled, severe and complicated hypertension, we used multivariable mixed logistic regressions, and to model the association with blood pressure (systolic (SBP) and diastolic (DBP)) we used mixed linear models. All models were adjusted for age, sex, wealth, adherence to hypertension conventional treatment and country (random effect). Results A total of 512 (24%) participants reported using TM, varying across countries from 10% in the Congo to 48% in Guinea. TM users were more likely to be men, living in rural area, poorly adhere to prescribed medication (frequently due to its cost). Use of TM was associated with a 3.87 (95% CI 1.52 to 6.22)/1.75 (0.34 to 3.16) mm Hg higher SBP/DBP compared with no use; and with greater odds of severe hypertension (OR=1.34; 95% CI 1.04 to 1.74) and of any hypertension complication (OR=1.27; 95% CI 1.01 to 1.60), mainly driven by renal complication (OR=1.57; 95% CI 1.07 to 2.29) after adjustment for measured confounders. Conclusions The use of TM was associated with higher blood pressure, more severe hypertension and more complications in Sub-Saharan African countries. The widespread use of TM needs to be acknowledged and worked out to integrate TM safely within the conventional healthcare.

Abstract
Antibiotic resistance and the hazardous nature of synthetic drugs is threatening issue in the health sector. The alternative for this problem is to focus on plants that attribute to various compounds that exhibit therapeutic properties. Therefore, the study aims to evaluate the antimicrobial efficacy of Salacia oblonga leaf and root extracts against tested human pathogens. The S. oblonga extracts showed a significant zone of inhibition against bacteria and fungi. The leaf and root extracts of S. oblonga are prepared using low polar to high polar solvents in the Soxhlet apparatus and tested on the selected bacterial and fungal strains. Agar well diffusion and broth dilution methods evaluate antibacterial activity, antifungal activity, and Minimum Inhibitory Concentration (MIC) of extracts. Among the extracts tested, the ethyl acetate extract of root showed more antimicrobial activity against the tested bacterial and fungal strains. The most susceptible bacterial and fungal species against ethyl acetate extract are Micrococcus luteus, Mycobacterium tuberculosis, Microsporum canis, Trichophyton interdigitale, and Microsporum gypseum. The MIC for bacteria ranged from 13.0 to > 200 µg/ml, whereas for fungi, the MIC ranged from 25.9 to > 200 µg/ml. Ethyl acetate extract of root with 100 µg/ml concentration showed 29.1 mm and 28.7 mm zone of inhibition against bacterial strains M. luteus and M. tuberculosis, respectively. The ethyl acetate extract of root with a 100 µg/ml concentration showed 15.8, 15.2, and 15.6 mm zone of inhibition against fungal isolates M. canis, T. interdigitale, and M. gypseum, respectively. The activity of root and leaf extracts increased in a concentration-dependent manner, and further, the compounds isolated from the crude extracts of leaf and root showed antimicrobial activity. Structural elucidation of isolated compounds Lambertic acid and Ferruginol was done using NMR spectroscopy. Reports indicate that Lambertic acid was isolated previously, but the isolation of hydroxy Ferruginol from S. oblonga leaf extract was reported unprecedented.

Abstract
Camel milk (CM) has been found to have several health benefits, including antiviral, antibacterial, anti-tumor, anti-fungal, antioxidant, hypoglycaemic and anti-cancer activities. In addition, CM can counter signs of aging and may be a useful naturopathic treatment for autoimmune diseases. The composition of CM varies with geographic origin, feeding conditions, seasonal and physiological changes, genetics and camel health status. In the present review, we collate the diverse scientific literature studying antioxidant, anti-inflammatory and immunomodulatory effects of CM and its bioactive compounds. The databases Scopus, PubMed, and Web of Science were searched until the end of September 2021 using the keywords: camel milk, antioxidant, anti-inflammatory, immunomodulatory. The anti-inflammatory mechanism of CM in various inflammatory disorders was consistently reported to be through modulating inflammatory cells and mediators. The common anti-inflammatory bioactive components of CM seem to be lactoferrin. The antioxidant effects of α-lactalbumin, β-caseins and vitamin C of CM work by reducing or inhibiting the production of reactive oxygen species (ROS), hydroxyl radicals, nitric oxide (NO), superoxide anions and peroxyl radicals, likely alleviating oxidative stress. Higher levels of protective proteins such as lysozyme, IgG and secretory IgA compared to cow's milk, and insulin-like protein activity of CM on ß cells appear to be responsible for the immunomodulatory properties of CM. The evidence indicates that CM and its bioactive components has the potential to be a therapeutic value for diseases that are caused by inflammation, oxidative stress and/or immune-dysregulation.

Abstract
BACKGROUND Transforming growth factor beta (TGF-β) superfamily has key role in cell proliferation which leads to tumor promoting activities at metastatic stage of cancer. Inhibition of transforming growth factor beta receptor (TGFβR) signaling pathway can provide better therapeutic strategy to control cancer. Natural products are best known for their safety, less toxic nature, antioxidant characteristics making them a promising candidate to inhibit TGFβR signaling pathway. METHODS AND RESULTS Crude methanolic extracts (CMEs) of 16 selected plants were prepared by using maceration method and subjected to phytochemical assays for identification of major phytometabolites particularly cancer chemopreventive antioxidant constituents. Total flavonoid content of all plants CME was > 0.6 mg/ml exhibiting the Cichorium intybus contains comparatively highest amount of total flavonoid content (0.53 mg/ml). Scanvenging activity of all plants was determined having IC50 ranges between 2 and 88 (µg/ml) while Moringa oleifera revealed the maximum scavenging activity (IC50 2.03 µg/ml). Comparative cytotoxicity of plant extracts was evaluated in HUH and MCF-7 cell lines using 3-(4,5-Dimethylthiazol-2-Yl)-2,5-Diphenyltetrazolium Bromide (MTT) colorimetric assay. The nine active plant extracts i.e. Fagonia cretica, Argemone Mexicana, Rubus fruticosus, M. oleifera, Punica granatum, Cichorium intybus, Xanthium strumarium, Carissa opaca, Cyperus rotundus were identified based on their high antiproliferative activity > 50% against cancer cell lines and subjected to relative expression studies. Modulation of TGFβ signaling molecules (i.e.TGFβR1, 2 & 3, SMAD3, SMAD5) and ubiquitous proteins i.e. SMURF1 and SMURF2 genetic expression by potent extracts was determined by RT-PCR using GAPDH (housekeeping gene) as gene of reference. CONCLUSIONS This present study revealed that CME of Fagonia cretica and Argemone mexicana significantly inhibit TGF beta mediated signaling cascade by downregulating the gene expression fold change > 1 of TGFβR 1, 2 & 3 and receptor associated complex protein SMAD3 as compared to control.

Abstract
BACKGROUND Trunk flexion is a common exercise during daily activities. Flexion relaxation phenomenon (FRP) occurs during forward bending in which there is a sudden silence of erector spinae (ES) muscles. The pattern of forward bending differs in yoga practitioners. This learned pattern probably predisposes yogis to injuries. The hypothesis of this study was that FRP differs in yogis in comparison to non-yogis individuals. METHODS This observational cross-sectional study was performed on 60 women assigned into yogis and non-athlete groups. Each participant was asked to bend forward and then return to the initial position. ES activity was recorded at L3 level, 4 cm from mid line during the trial. Trunk inclination and lumbar flexion angles were calculated at FRP onset and cessation moments. RESULTS The FRP occurred in 80% of yoga practitioners in comparison to 96.7% in the control group. Trunk inclination angle was significantly greater at FRP initiation in yogis compared to control group. Lumbar flexion angle was not different between the groups. CONCLUSIONS It is concluded that the altered pattern of forward bending observed in yogis may change patterns of ES muscles activity if it becomes part of a person's daily lifestyle which might predispose these muscles to fatigue and subsequent injuries; however, further studies are warranted for clarification.

Abstract
Cadmium is a toxic metal and poses a high environmental risk to animals and humans, alike. It is thus pertinent to search for medicinal plants in protecting against cadmium toxicity. This study aims at investigating the ability of aqueous extract of Persea americana seeds (AEPA) in ameliorating the toxic effects of cadmium in the kidneys of cadmium-exposed Wistar rats. Male Wistar rats were grouped into five, of six animals each. Different groups of animals received normal saline (control group), 200 mg/kg body weight AEPA, 400 mg/kg AEPA, and standard drug, Livolin Forte, respectively. A last group of animals was left untreated. To induce toxicity, all animals, except the control group, were exposed to cadmium (200 mg/L, as CdCl2) in their main drinking water for 21 days. Biochemical analysis of serum kidney markers, oxidative stress and antioxidant status, as well as anti-inflammatory activities, was done using standard methods and kits. In silico analysis was performed on phytochemicals reported to be abundant in AEPA. Treatment with 400 mg/kg AEPA significantly reversed (P ≤ 0.05) the adverse effect of cadmium on serum creatinine, urea, uric acid and blood urea nitrogen, and restored (P ≤ 0.05) antioxidant status, evidenced by its significant effect on superoxide dismutase, catalase, glutathione-S-transferase, glutathione peroxidase, reduced glutathione, and lipid peroxidation activities. AEPA, at 400 mg/kg also exhibited significant anti-inflammatory effects, which was shown by reduced interleukin-2 and tumour necrosis factor α activities. Molecular docking of phytochemicals with the selected protein target also confirmed the therapeutic potential of AEPA. The study concluded that aqueous extract of AEPA protects against cadmium-induced kidney toxicity and inflammation.

Seasonal dynamics of the phenolic constituents of the cones and leaves of oriental Thuja ( Platycladus orientalis L.) reveal their anti-inflammatory biomarkers. RSC Adv 2021; 11:24624-24635.

Abstract
In this study, the seasonal dynamics of the flavonoids in the cones and leaves of oriental Thuja (Platycladus orientalis L. Franco) as well as the in vitro anti-inflammatory activity of their extracts were investigated. The important chemical markers of the studied extracts were determined using untargeted HPTLC profiling, which was further utilized to assess the seasonality effect on the composition of these metabolites over three seasonal cycles. A quantitative HPTLC method was developed and validated for the identified chemical markers of oriental Thuja: hyperoside, quercetrin, isoscutellarein-7-O-β-xyloside, cupressuflavone, hinokiflavone, sotetsuflavone and isoscutellarein-8-methyl ether. The highest amounts of flavonoids were observed during the summer and winter seasons, where the leaves possessed higher contents of flavonoids compared to cones. Flavone glycosides are a major class of flavones encountered in leaves, while the cones mainly accumulated biflavones. The results showed that the effect of seasonal variation on the accumulation of flavonoids within the cones was less pronounced than in the leaves. The summer leaves showed a remarkable reduction in the levels of INF-γ, where the value decreased to 80.7 ± 1.25 pg mL−1, a significantly lower level than that obtained with piroxicam (180 ± 1.47 pg mL−1); this suggests a noteworthy anti-inflammatory potential. OPLS (orthogonal projection to latent structures) models showed that flavonoidal glycosides, quercetrin, hyperoside and isoscutellarein-7-O-β-xyloside were the most contributing biomarkers to the reduction in pro-inflammatory mediators in LPS-stimulated WBCs. The results obtained in the study can thus be exploited to establish the best organs as well as the optimal periods of the year for collecting and obtaining certain biomarkers at high concentrations to guarantee the efficacy of the obtained extracts. In this study, the seasonal dynamics of the flavonoids in the cones and leaves of oriental Thuja (Platycladus orientalis L. Franco) as well as the in vitro anti-inflammatory activity of their extracts were investigated.![]()

Abstract
Peganum harmala (P. harmala) is a folk medicinal herb used in the Sinai Peninsula (Egypt) as a remedy for central disorders. The main constituents, harmine and harmaline, have displayed therapeutic efficacy against Alzheimer's disease (AD); however, the P. harmala potential on sensitizing central insulin to combat AD remains to be clarified. An AD-like rat model was induced by aluminum chloride (AlCl3; 50 mg/kg/day for six consecutive weeks; i.p), whereas a methanolic standardized P. harmala seed extract (187.5 mg/kg; p.o) was given to AD rats starting 2 weeks post AlCl3 exposure. Two additional groups of rats were administered either the vehicle to serve as the normal control or the vehicle + P. harmala seed extract to serve as the P. harmala control group. P. harmala enhanced cognition appraised by Y-maze and Morris water maze tests and improved histopathological structures altered by AlCl3. Additionally, it heightened the hippocampal contents of glucagon-like peptide (GLP)-1 and insulin, but abated insulin receptor substrate-1 phosphorylation at serine 307 (pS307-IRS-1). Besides, P. harmala increased phosphorylated Akt at serine 473 (pS473-Akt) and glucose transporter type (GLUT)4. The extract also curtailed the hippocampal content of beta amyloid (Aβ)42, glycogen synthase (GSK)-3β and phosphorylated tau. It also enhanced Nrf2, while reduced lipid peroxides and replenished glutathione. In conclusion, combating insulin resistance by P. harmala is a novel machinery in attenuating the insidious progression of AD by enhancing both insulin and GLP-1 trajectories in the hippocampus favoring GLUT4 production.

Abstract
Amyloid beta (Aβ) is a neurotoxic peptide, and the accumulation of Aβ in the brain is the major characteristic of Alzheimer's disease (AD). Recently, the beneficial effects of Cirsium japonicum var. maackii (CJM) on brain health has attracted much attention. In the present study, we investigated the ability and protective mechanisms of CJM to attenuate neuronal toxicity caused by Aβ using SH-SY5Y cells. Aβ25-35 treatment decreased cell viability, whereas CJM extract/fractions increased cell viability in Aβ25-35-treated cells. We found that CJM treatment prevented the accumulation of reactive oxygen species observed in Aβ25-35-treated control cells. Furthermore, Aβ25-35-mediated production of inflammatory cytokines such as interleukin-1β was significantly suppressed by CJM. In addition, apoptotic factors were modulated in CJM-treated cells by downregulating B-cell lymphoma-2-associated X protein and upregulating B-cell lymphoma-2 protein expression. The assays showed that the ethyl acetate (EtOAc) fraction of CJM has greater neuroprotective bioactivities compared with the other extract/fractions. The main neuroprotective active compound from the EtOAc fraction of CJM was identified as pectolinarin using ultraperformance liquid chromatography-quadrupole time-of-flight-mass spectrometry. Collectively, this study not only describes the neuroprotective effect of CJM against Aβ25-35via the regulation of oxidative, inflammatory, and apoptotic signaling pathways, but also provides useful information for future studies on the mechanism of novel medicinal sources based on pectolinarin isolated from CJM.

Abstract
Purposes: The present study aimed to develop brimonidine tartrate loaded poly(lactic-co-glycolic acid) acid vitamin E-tocopheryl polyethylene glycol 1000 succinate (BRT-PLGA-TPGS) nanoparticles in thermosensitivein situ gel to improve mucoadhensive properties and drug holding capacity for the better management of glaucoma.Methods: Nanoparticles was optimized by means of Box-Behnken Design (BBD). The formulations were prepared using various concentration of PLGA (0.1-0.4% w/v) and TPGS (0.3-0.5% w/v). The analytical data of fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and transmission electron microscopy (TEM) depicted the drug excipients compatibility and confirmed the nanoparticles. Nanoparticles incorporated gel was evaluated for transcorneal permeability, gelation time, gelling temperature, and rheological studies. In addition, in vitro, transcorneal permeation drug release studies and intraocular pressure (IOP) for optimized gel was also performed. Biocompatibility of formulations was investigated in rabbit model.Results: The drug loaded nanoparticles exhibited 115.72 ± 4.18 nm, 0.190 ± 0.02, -11.80 ± 2.24 mV and 74.85 ± 6.54% of mean size, polydispersity index (PDI), zeta potential and entrapment efficiency (% EE), respectively. As compared to marketed eye drop, the sustained and continuous release BRT release from Poloxamer-based in situ gel was 85.31 ± 3.51% till 24 h. The transcorneal steady-state flux (136.32 μg cm-2 h-1) of optimized in situ gel was approximately 3.5 times higher than marketed formulation (38.60 μg cm-2 h-1) flux at 4 h. The optimized formulation produces 3 fold greater influences on percentage reduction of IOP (34.46 ± 4.21%) than the marketed formulation (12.24 ± 2.90%) till 8 h.Conclusion: The incorporation of optimized BRT-PLGA-TPGS nanoparticles into a thermosensitivein situ gel matrix to improve precorneal residence time without causing eye irritation and also serve the sustained release of BRT through cornea for effective management of glaucoma.

Abstract
OBJECTIVE Evaluation of the healing and toxicological effects of Copaifera duckei Dwyer oleoresin (CDO). MATERIALS AND METHODS Rodents with skin lesions were divided into nine groups, including daily treatments with 1, 3 and 10% CDO, collagenase, antibiotic ointment and control groups, for 14 days. RESULTS Treatment with 10% CDO reduced skin edema and hyperplasia, demonstrating anti-inflammatory effect of the oil. Reduction in the wound area was observed, indicating the healing effect of CDO. Histopathological analysis showed increases in angiogenesis and re-epithelialization in animals treated with the highest concentration. On the other hand, no alterations in ulcerations, inflammatory infiltrate, hemorrhage, congestion, degeneration, percentage of collagen fibers, number of cells stained with anti-macrophage migration inhibitory factor, or density of area stained with anti-collagen I and III were found. Toxicogenetic analysis revealed no differences in micronucleus frequencies or in the ratio of polychromatic erythrocytes to total erythrocytes between treated and negative control, demonstrating the absence of genotoxicity and cytotoxicity, respectively. There was no difference in levels of liver enzymes among groups, indicating the absence of hepatotoxicity. CONCLUSION Formulations of CDO exerted beneficial effects on the stages of cutaneous wound healing and are promising options for the treatment of wounds.

Abstract
The purified oxindole alkaloids, isomitraphylline and mitraphylline from Uncaria perrottetii, revealed their ability to break amyloid aggregates in vitro suggesting their therapeutic potentials in Alzheimer's disease (AD). Thioflavin-T assay for assessing amyloid-beta (Aβ) aggregation of these alkaloids exhibited inhibitions at 60.321% ± 2.61 (50 μM) for isomitraphylline and 43.17% ± 3.48 (50 μM) for mitraphylline. Neuroprotective effects were elaborated against Aβ-induced SH-SY5Y cells at 20 μM and 10 μM for isomitraphylline, and 20 μM for mitraphylline. In addition, both alkaloids attenuated and protected the H2O2-induced SH-SY5Y cell cytotoxicity at 20 μM. The intracellular ROS levels of SH-SY5Y cells from H2O2-induced oxidative stress were reduced at 20 μM and 10 μM, and the mitochondrial membrane potentials of Aβ-induced SH-SY5Y cells were protected at 20 μM. The overall results suggested the potentials of both alkaloids to target certain pathological biomarkers of AD and could be further investigated as therapeutic or preventive drug leads against AD.

Abstract
Trichoderma is a saprophytic, soil-borne fungus with a worldwide distribution that has been extensively studied due to their capacity to synthesize secondary metabolites with antimicrobial activity, parasitize other fungi and directly interact with plant roots, inducing resistance to disease and tolerance to abiotic stresses. Fusarium wilt caused by the soil-inhabiting fungus Fusarium oxysporum is considered one of the most important diseases that affect banana cultivars. Currently, more environmentally friendly alternatives to control this disease are being proposed, these strategies include the application of low doses of synthetic fungicides and the use of biocontrol agents such as Trichoderma or Xylaria. Thus, this study aimed to evaluate under in vitro conditions the synergistic effect of the biological control agent T. reesei C2A combined with low doses of mancozeb to inhibit the mycelial growth of F. oxysporum F1. To perform the synergistic essays, 0.1 mg/mL of mancozeb was suspended in PDA plates, then plugs of T. ressei C2A were placed at the center of the Petri dishes, the plates were incubated for 7 days at 28°C. Results showed that the mycoparasitic capacity of the biocontrol strain to inhibit the mycelial growth of F. oxysporum F1 was enhanced approximately 36% compared to the control plates. Although these results are promising, future studies under greenhouse and field conditions are necessary to corroborate the effectiveness of this approach.

Abstract
We used a type 2 diabetes rat model produced by a high fat diet (HFD) followed by low dose streptozotocin (STZ) to study diabetic vasculopathy. Animals were evaluated for early vascular structural changes, endothelial function, inflammation, lipid profile and oxidative stress. We used 20 male Sprague-Dawley rats divided equally into control and diabetic groups. Diabetic rats were fed an HFD for 4 weeks, injected intraperitoneally with STZ, then sacrificed at week 15. Aortic endothelial nitric oxide synthase (eNOS), aortic superoxide dismutase (SOD), endothelial-dependent and independent relaxation and contraction, intima-media thickness (IMT), malondialdehyde (MDA) and tumor necrosis factor-alpha (TNF-α) were measured. Histopathological characteristics also were assessed. Diabetic rats exhibited higher fasting blood glucose (FBG), low density lipoprotein, total cholesterol and triglycerides compared to the control group. Aortic endothelium-dependent relaxation due to acetylcholine (ACh) was lower, while aortic endothelium-dependent contraction due to calcium ionophore and endothelium-independent contraction due to phenylephrine (PE) were higher for the diabetic group. eNOS expression was lower in the diabetic group compared to controls. IMT and MDA levels were increased, while SOD activity was decreased in the diabetic group compared to controls. TNF-α was higher in the diabetic group than for controls. Our type 2 diabetes model exhibited endothelial dysfunction associated with early vascular structural changes, dyslipidemia, increased vascular oxidative stress, and inflammation. Therefore, the model is suitable for studying diabetic atherosclerosis.

Abstract
Abstract
Background
The fruits of P. macrocarpa have long been used as a traditional Malay medicinal herb for hundreds of years. Intraperitoneal (i.p.) injection of streptozotocin (STZ) (65 mg/kg) was used to induce diabetes in rats confirmed by an oral glucose tolerance test (OGTT). The ethanol extract of P. macrocarpa (EEPM) fruits at 100 and 200 mg/kg were given orally for 35 days, glibenclamide. In total, 0.5 mg/kg served as a positive control.
Results
The present toxicity study suggests that the EEPM fruits are non-toxic. In an OGTT, the EEPM at 50, 100, and 200 mg/kg and glibenclamide (0.5 mg/kg) reduced the blood glucose level (hyperglycemia due to glucose load 2 g/kg p.o.) significantly after 2 h of oral administration, when compared to the diabetic control. Repeated oral administration of EEPM daily for up to 35 days exhibited significant antidiabetic activity in STZ-induced diabetic rats compared to the diabetic control. At the end of 35 days of treatment, the 200 mg/kg (EEPM) dose was found to be more effective than the 100 and 50 mg/kg (EEPM) doses and blood glucose levels decreased from 392.66 ± 3.20 to 174.33 ± 4.32 mg/dl (p ˂ 0.01). In contrast, on day 35, the blood glucose levels of the normal control, drug control, and diabetic control were 132.16 ± 5.79, 134.33 ± 7.18 (p ˂ 0.01), and 514.83 ± 7.96 respectively. From histology analysis, the pancreases of the diabetic control were granulated and dilated islet cells, whereas in the drug control they appeared granulated, without dilation and important hyper plasticity of islets. The treatment groups (EEPM 100 and 200 mg/kg) also showed granulated pancreatic islets and prominent hyper plasticity islets. Light micrographs in various regions of rat kidney tissue from the treatment groups showed absence of matrix expansion and glomerular basement membrane thickening, suggesting it became normal histoarchitecture of the renal. Biochemical aspects in treating animals’ all serum analytic parameters were almost similar to the drug control group with the exception of the 50 mg/kg treatment group.
Conclusion
In this way, it may also serve as a good alternative in the present armamentarium of antidiabetic drugs.

Abstract
The widespread emergence of cancer and development of resistance to chemotherapeutic agents is increasing the interest of scientists in the use of ethnomedicinal preparations and isolated phytochemicals in the treatment and prevention of disease. Medicinal plants have been used in Pakistan since prehistoric times. The present review was designed to identify anticancer plants of ethnomedicinal significance and to summarize the anticancer activities carried out on these medicinal plants to establish the pharmacological and phytochemical basis of their use. Pakistani anticancer medicinal plants of ethnopharmacological significance were reviewed. Conservation status, worldwide distribution and ethno-botanical preparations of these medicinal plants were also tabulated. These medicinal plants and their isolated phytochemicals were also explored for their anticancer activities. It was revealed that there were 108 anticancer medicinal plants used to treat different neoplastic conditions on the folklore basis throughout Pakistan. Among these anticancer plants, 64 plants were found to be investigated previously for anticancer activity through in vivo and in vitro methods. Several ethnomedicinal plants have been validated for their anticancer activities through in vitro and animal models. These medicinal plants and phytochemicals resulted in the inhibition of initiation, progression or metastasis of neoplasm. Some medicinal plants (10) are endangered species. Half of folkloric Pakistani plants have been validated for use against various cancers through in vitro or in vivo methods. It is necessary to carry out further pharmacological and toxicological evaluation of these folkloric anticancer plants of Pakistan. It is also necessary to identify and isolate further potential phytochemicals so as to be evaluated in cancer patients.

Abstract
BACKGROUND Defense personnel utilize capsaicin-based ocular sprays as non-lethal agents for law implementation during instances of mob violence. This study involves the capsaicin antagonist Capsazepine and the investigation of whether Capsazepine's antagonistic approach can be favorably utilized for defense utilization to block capsaicin-initiated pain and inflammation via the ocular pathway. RESEARCH DESIGN AND METHODS Ocular capsazepine in situ gels were prepared with polymers Pluronic F-127 and Chitosan; optimized formulation was quantified in ocular tissues chromatographically and by in vivo live ocular imaging; anti-inflammatory efficacy was determined by eye irritation testing, corneal and retinal imaging, ocular prostaglandin estimation, and by viability and proliferation testing using human ocular cell lines, etc. RESULTS A physicochemically stable Capsazepine in situ gel was formulated which showed little ocular irritation, considerable transcorneal permeation; was precisely quantified in ocular tissues by gas chromatography and in vivo live ocular imaging; showed anti-inflammatory properties against capsaicin by eye imaging experiments, prostaglandin declination and showed acceptable cytocompatibility when studied using human ocular cell lines. CONCLUSIONS The fabricated in situ Capsazepine gel system might be promising for ocular delivery as it appears a pharmacologically potent and safe development, suitable for utilization in the ocular clinical therapy, provided there is additional research to substantiate it.

Abstract
Cataract is the most common cause of blindness in the world; during infancy and early childhood, it frequently results in visual impairment. Congenital cataracts are phenotypically and genotypically heterogeneous and can occur in isolation or in association with other systemic disorders. Significant progress has been made in identifying the molecular genetic basis of cataract; 115 genes to date have been found to be associated with syndromic and non-syndromic cataract and 38 disease-causing genes have been identified to date to be associated with isolated cataract. In this review, we briefly discuss lens development and cataractogenesis, detail the variable cataract phenotypes and molecular mechanisms, including genotype-phenotype correlations, and explore future novel therapeutic avenues including cellular therapies and pharmacological treatments.
