Abstract
OBJECTIVES Rhus coriaria L. (RC) is a deciduous shrub with several pharmacological activities. Evidence of the effects of RC on weight, hyperlipidaemia, hypertension and diabetes mellitus have been presented in this study. Books, thesis and internet-based resources such as PubMed, Web of Science, Scopus, EMBASE, Cochrane, Ovid and Google Scholar were searched for the English, Arabic and Persian literature from 1966 to 2020 (December). The keywords were Rhus coriaria L., Sumac, metabolic syndrome and all its medical conditions (hyperlipidaemia, hypertension, obesity and diabetes mellitus). The inclusion criteria were full-text animal and human studies conducted on RC to evaluate its efficacy on any components of metabolic syndrome (MetS). Jadad scale was used to assess the quality of evidence. KEY FINDINGS Reviewing 23 relevant studies demonstrated that RC is able to decrease the level of blood glucose, glycated haemoglobin, serum insulin and insulin resistance. Studies on hyperlipidaemia and obesity have very contradicting results, and there is no definite conclusion on the effect of RC on lipid profile. However, the hypotensive and effect of RC was confirmed in the existing studies. SUMMARY According to the literature, RC can be considered as a promising curative candidate for MetS. However, further studies with larger sample size and higher methodological quality are needed.

Non-estrogenic Xanthohumol Derivatives Mitigate Insulin Resistance and Cognitive Impairment in High-Fat Diet-induced Obese Mice. Sci Rep 2018; 8:613. [PMID: 29330372 PMCID: PMC5766630 DOI: 10.1038/s41598-017-18992-6] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2017] [Accepted: 12/20/2017] [Indexed: 01/21/2023] Open
Abstract
Xanthohumol (XN), a prenylated flavonoid from hops, improves dysfunctional glucose and lipid metabolism in animal models of metabolic syndrome (MetS). However, its metabolic transformation into the estrogenic metabolite, 8-prenylnaringenin (8-PN), poses a potential health concern for its use in humans. To address this concern, we evaluated two hydrogenated derivatives, α,β-dihydro-XN (DXN) and tetrahydro-XN (TXN), which showed negligible affinity for estrogen receptors α and β, and which cannot be metabolically converted into 8-PN. We compared their effects to those of XN by feeding C57BL/6J mice a high-fat diet (HFD) containing XN, DXN, or TXN for 13 weeks. DXN and TXN were present at higher concentrations than XN in plasma, liver and muscle. Mice administered XN, DXN or TXN showed improvements of impaired glucose tolerance compared to the controls. DXN and TXN treatment resulted in a decrease of HOMA-IR and plasma leptin. C2C12 embryonic muscle cells treated with DXN or TXN exhibited higher rates of uncoupled mitochondrial respiration compared to XN and the control. Finally, XN, DXN, or TXN treatment ameliorated HFD-induced deficits in spatial learning and memory. Taken together, DXN and TXN could ameliorate the neurocognitive-metabolic impairments associated with HFD-induced obesity without risk of liver injury and adverse estrogenic effects.

Abstract
AIM This study aimed to evaluate the prevalence of overweight and obesity derived from measured data of weight and height in a cross-sectional sample of adolescents in the Italian region of Lazio and to analyse their association with different socio-demographic factors. METHODS The study was conducted in a representative sample of 15-16-year-old adolescents recruited in secondary schools between December 2011 and May 2012. 369 adolescents were investigated. Body weight, height and waist circumference were measured. The BMI of each subject was calculated, and the prevalence of overweight and obesity was determined by age and sex using the IOTF reference values and WHO growth standards. Waist circumference/height ratio (WC/Ht) was calculated and the subjects were classified using the cut-off of 0.5: WC/Ht≥0.5 and WC/Ht<0.5. Selected socio-demographic characteristics were assessed via questionnaire. RESULTS The percentages of overweight and obesity were high, 15.4% and 7.9%, respectively, with significant difference between males and females (19.1% vs. 12.6% for overweight and 11.1% vs. 5.3% for obese) using the IOFT reference. The ratio WC/Ht≥0.5 was observed in 12.7% of the sample (all the obese and 29.8% of the overweight subjects). Multiple logistic regression analysis indicated that gender, school municipality, mother's employment status, and family structure had a significant effect on ponderal status (overweight/obesity vs. normal weight). CONCLUSION These findings show a high prevalence of body weight excess associated with socio-demographic factors in the Italian sample investigated, and the need for effective public health interventions to combact obesity with particular attention to disadvantaged adolescents.

Abstract
The extract of chestnut (Castanea crenata var. dulcis) flower (CCDF) has antioxidant and antimelanogenic properties, but its anti-obesity properties have not been previously examined. In this study, we tested the effect of CCDF absolute on adipocyte differentiation by using 3T3-L1 cells and determining the bioactive component of CCDF absolute in 3T3-L1 cell differentiation. CCDF absolute (0.1-100[Formula: see text][Formula: see text]g/mL) did not change 3T3-L1 cell viability. At 50[Formula: see text][Formula: see text]g/mL and 100[Formula: see text][Formula: see text]g/mL, the absolute significantly reduced the accumulation of lipid droplets in 3T3-L1 cells that were induced by culture in medium containing 3-isobutyl-1-methylxanthine/dexamethasone/insulin (MDI). GC/MS analysis showed that CCDF absolute contains 10 compounds. Among these compounds, cinnamyl alcohol (3-phenyl-2-propene-1-ol) dose-dependently inhibited the increased accumulation of lipid droplets in MDI-contained medium-cultured 3T3-L1 cells at a concentration range of 0.1[Formula: see text][Formula: see text]g/mL to 10[Formula: see text][Formula: see text]g/mL that did not cause cytotoxicity in 3T3-L1 cells. The inhibitory effect was significant at 5[Formula: see text][Formula: see text]g/mL ([Formula: see text] of response in MDI alone-treated state, [Formula: see text]) and 10[Formula: see text][Formula: see text]g/mL ([Formula: see text] of response in MDI alone-treated state, [Formula: see text]). Moreover, the enhanced expression of obesity-related proteins (PPAR[Formula: see text], C/EBP[Formula: see text], SREBP-1c, and FAS) in MDI medium-cultivated 3T3-L1 cells was significantly attenuated by the addition of cinnamyl alcohol at 5[Formula: see text][Formula: see text]g/mL and 10[Formula: see text][Formula: see text]g/mL. These findings demonstrate that cinnamyl alcohol suppresses 3T3-L1 cell differentiation by inhibiting anti-adipogenesis-related proteins, and it may be a main bioactive component of CCDF absolute, exerting antidifferentiation action in 3T3-L1 cells. Therefore, cinnamyl alcohol, as well as CCDF absolute, may be potential candidates for the prevention or treatment of obesity.

Abstract
Xanthohumol (XN) is a prenylated flavonoid found in hops (Humulus lupulus) and beer. The dose-dependent effects of XN on glucose and lipid metabolism in a preclinical model of metabolic syndrome were the focus of our study. Forty-eight male C57BL/6J mice, 9 weeks of age, were randomly divided into three XN dose groups of 16 animals. The mice were fed a high-fat diet (60% kcal as fat) supplemented with XN at dose levels of 0, 30, or 60 mg/kg body weight/day, for 12 weeks. Dietary XN caused a dose-dependent decrease in body weight gain. Plasma levels of glucose, total triglycerides, total cholesterol, and MCP-1 were significantly decreased in mice on the 60 mg/kg/day treatment regimen. Treatment with XN at 60 mg/kg/day resulted in reduced plasma LDL-cholesterol (LDL-C), IL-6, insulin and leptin levels by 80%, 78%, 42%, and 41%, respectively, compared to the vehicle control group. Proprotein Convertase Subtilisin Kexin 9 (PCSK-9) levels were 44% lower in the 60 mg/kg dose group compared to the vehicle control group (p ≤ 0.05) which may account for the LDL-C lowering activity of XN. Our results show that oral administration of XN improves markers of systemic inflammation and metabolic syndrome in diet-induced obese C57BL/6J mice.

N-Acetylneuraminic Acid Supplementation Prevents High Fat Diet-Induced Insulin Resistance in Rats through Transcriptional and Nontranscriptional Mechanisms. BIOMED RESEARCH INTERNATIONAL 2015; 2015:602313. [PMID: 26688813 PMCID: PMC4673348 DOI: 10.1155/2015/602313] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/25/2015] [Revised: 10/29/2015] [Accepted: 11/04/2015] [Indexed: 12/26/2022]
Abstract
N-Acetylneuraminic acid (Neu5Ac) is a biomarker of cardiometabolic diseases. In the present study, we tested the hypothesis that dietary Neu5Ac may improve cardiometabolic indices. A high fat diet (HFD) + Neu5Ac (50 or 400 mg/kg BW/day) was fed to rats and compared with HFD + simvastatin (10 mg/kg BW/day) or HFD alone for 12 weeks. Weights and serum biochemicals (lipid profile, oral glucose tolerance test, leptin, adiponectin, and insulin) were measured, and mRNA levels of insulin signaling genes were determined. The results indicated that low and high doses of sialic acid (SA) improved metabolic indices, although only the oral glucose tolerance test, serum triglycerides, leptin, and adiponectin were significantly better than those in the HFD and HFD + simvastatin groups (P < 0.05). Furthermore, the results showed that only high-dose SA significantly affected the transcription of hepatic and adipose tissue insulin signaling genes. The data suggested that SA prevented HFD-induced insulin resistance in rats after 12 weeks of administration through nontranscriptionally mediated biochemical changes that may have differentially sialylated glycoprotein structures at a low dose. At higher doses, SA induced transcriptional regulation of insulin signaling genes. These effects suggest that low and high doses of SA may produce similar metabolic outcomes in relation to insulin sensitivity through multiple mechanisms. These findings are worth studying further.

Abstract
Background Serum sialic acid levels are positively correlated with coronary artery disease and inflammation. Although sialic acid is a non-specific marker, it is considered sensitive likely due to its influence in sialylation of glycoprotein structures all over the body. Objectives We hypothesized that dietary supplementation with N-acetylneuraminic acid (Neu5Ac), a type of sialic acid, will have profound effects on high fat diet- (HFD-) induced inflammation and oxidative stress in view of the widespread incorporation of sialic acid into glycoprotein structures in the body. Methods HFD-fed rats with or without simvastatin or Neu5Ac (50 and 400 mg/kg/day) were followed up for 12 weeks. Lipid profiles, and markers of inflammation (C-reactive protein, interleukin-6, and tumor necrosis factor alpha), insulin resistance (serum insulin and adiponectin, oral glucose tolerance test and homeostatic model of insulin resistance) and oxidative stress (total antioxidant status and thiobarbituric acid reactive species) in the serum and liver were determined, while mRNA levels of hepatic antioxidant and inflammation genes were also quantified. Serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, urea, creatinine and uric acid were also assessed. Results HFD feeding caused hyperlipidemia and insulin resistance, and worsened liver and kidney functions. HFD feeding also potentiated inflammation and oxidative stress, partly through modulation of hepatic gene expression, while Neu5Ac especially at higher doses and simvastatin attenuated HFD-induced changes, although Neu5Ac showed better outcomes. Conclusions Based on the present results, we surmised that Neu5Ac can prevent HFD-induced inflammation and oxidative stress, and may in fact be useful in the prevention of hyperlipidemia-associated inflammation and oxidative stress. However, the translational implications of these findings can only be determined after long-term effects are established. Hence, the use of Neu5Ac on obesity-related diseases requires additional attention.

Abstract
Edible bird's nest (EBN) is used traditionally in many parts of Asia to improve wellbeing, but there are limited studies on its efficacy. We explored the potential use of EBN for prevention of high fat diet- (HFD-) induced insulin resistance in rats. HFD was given to rats with or without simvastatin or EBN for 12 weeks. During the intervention period, weight measurements were recorded weekly. Blood samples were collected at the end of the intervention and oral glucose tolerance test conducted, after which the rats were sacrificed and their liver and adipose tissues collected for further studies. Serum adiponectin, leptin, F2-isoprostane, insulin, and lipid profile were estimated, and homeostatic model assessment of insulin resistance computed. Effects of the different interventions on transcriptional regulation of insulin signaling genes were also evaluated. The results showed that HFD worsened metabolic indices and induced insulin resistance partly through transcriptional regulation of the insulin signaling genes. Additionally, simvastatin was able to prevent hypercholesterolemia but promoted insulin resistance similar to HFD. EBN, on the other hand, prevented the worsening of metabolic indices and transcriptional changes in insulin signaling genes due to HFD. The results suggest that EBN may be used as functional food to prevent insulin resistance.

Abstract
Determination of pharmacokinetics (PKs) of multicomponent pharmaceuticals and/or nutraceuticals (polypharmacokinetics, poly-PKs) is difficult due to the vast number of compounds present in natural products, their various concentrations across a wide range, complexity of their interactions, as well as their complex degradation dynamics in vivo. Metabolomics coupled with multivariate statistical tools that focus on the comprehensive analysis of small molecules in biofluids is a viable approach to address the challenges of poly-PK. This paper discusses recent advances in the characterization of poly-PK and the metabolism of multicomponent xenobiotic agents, such as compound drugs, dietary supplements, and herbal medicines, using metabolomics strategy. We propose a research framework that integrates the dynamic concentration profile of bioavailable xenobiotic molecules that result from in vivo absorption and hepatic and gut bacterial metabolism, as well as the human metabolic response profile. This framework will address the bottleneck problem in the pharmacological evaluation of multicomponent pharmaceuticals and nutraceuticals, leading to the direct elucidation of the pharmacological and molecular mechanisms of these compounds.

Abstract
Yerba maté (mate) tea, a herbal tea prepared from the leaves of Ilex paraguariensis, is widely consumed in southern Latin America, and is gaining popularity worldwide. We investigated effects of an aqueous extract of mate on metabolic syndrome features in a metabolic syndrome model Tsumura Suzuki obese diabetic (TSOD) mouse. Oral administration of mate (100 mg/kg) for 7 weeks induced significant decreases in body weight, body mass index, and food intake in TSOD. It significantly decreased the hyperglycemia by reducing fasting blood glucose level, and increasing glucose uptake in glucose tolerance test. It also showed significant improvement in insulin sensitivity by increasing glucose uptake in insulin tolerance test, increasing quantitative insulin sensitivity check index, and decreasing homeostasis model assessment of insulin resistance index. The results also showed significant effects of mate on hyperlipidemia by decreasing blood levels of triglycerides, non-esterified fatty acids, and total cholesterol. Moreover, mate significantly improved adiponectin (AD) level, and exhibited significant reduction in white adipose tissue weight, and adiposity index in TSOD. It also showed significant ameliorative effects on TSOD histopathology, by reducing adipocytes proliferation, and improving hepatic steatosis. Furthermore, mate administration induced a dose-dependent delay in gastric emptying. The current data suggest that mate ameliorates metabolic syndrome by mechanisms involving increase of peripheral insulin sensitivity and cellular glucose uptake, and by modulating the level of circulating lipid metabolites and AD. These results indicate that mate can induce protective and ameliorative effects on insulin resistance, diabesity, and dyslipidemia in metabolic syndrome.

Abstract
Background Obesity and metabolic syndrome are important public concerns, and there is increasing demand for effective therapeutic strategies. Flavonoids are expected to improve the risk factors associated with metabolic syndrome. Anthocyanidins are a kind of flavonoids; well known for their anti-oxidative, anti-inflammatory and anti-tumor properties. However, their effects on adipocytes and molecular systems are not well defined. In this study, we examined the effects of anthocyanidins-enriched bilberry extracts on adipocyte differentiation. Methods Utilizing 3T3-L1 cell line, we investigated that bilberry extracts and anthocyanidins induced inhibition of lipid accumulation during adipogenesis. To identify what is the most important bilberry mediated-effect, we analyzed the expressions of key transcriptional factors associated with adipocyte differentiation by Real Time (RT)-PCR. From the results of RT-PCR, we hypothesized that bilberry extracts and anthocyanidins blocks insulin signal, we determined the phosphorylation of tyrosine residues of insulin receptor substrate 1 (IRS1) protein by western blotting analysis. In addition, we compared the whole-genome expression profiles of early stage of adipocyte differentiation under four different growth conditions (DMSO, bilberry, two anthocyanidins) by microarray analyses and Gene Set Enrichment Analysis (GSEA). Results Exposure to bilberry extracts and anthocyanidins during adipocyte differentiation inhibited 3T3-L1 differentiation. During this period, bilberry extracts and anthocyanidin significantly decreased a key adipocyte differentiation-associated marker, peroxisome proliferator-activated receptor- γ (Ppar γ ) and sterol regulatory element-binding protein 1c (Srebp1c). Western blotting analysis showed that bilberry extracts and anthocyanidin decreased the phosphorylation of tyrosine residues of IRS1. In addition, microarray experiments and GSEA data revealed significantly altered expression of the known genes of the insulin pathway in cells treated with bilberry extracts or anthocyanidins in the early differentiation stages. Conclusions Our data demonstrate that anthocyanidin enriched bilberry extracts strongly inhibit the adipocyte differentiation via the insulin pathway. Furthermore, bilberry extracts might be used as a potential complementary treatment for the obese patients with metabolic syndrome.

Abstract
Caffeine ranks as one of the top most commonly consumed dietary ingredients throughout the world. It is naturally found in coffee beans, cacao beans, kola nuts, guarana berries, and tea leaves including yerba mate. The total daily intake, as well as the major source of caffeine varies globally; however, coffee and tea are the 2 most prominent sources. Soft drinks are also a common source of caffeine as well as energy drinks, a category of functional beverages. Moderate caffeine consumption is considered safe and its use as a food ingredient has been approved, within certain limits, by numerous regulatory agencies around the world. Performance benefits attributed to caffeine include physical endurance, reduction of fatigue, and enhancing mental alertness and concentration. Caffeine has also been recently linked to weight loss and consequent reduction of the overall risks for developing the metabolic syndrome. However, the caloric contribution of caffeine-sweetened beverages needs to be considered in the overall energy balance. Despite all these benefits the potential negative effects of excessive caffeine intake should also be considered, particularly in children and pregnant women.

Abstract
BACKGROUND Celastrol, a quinone methide triterpenoid isolated from the Celastraceae family, exhibits various biological properties, including chemopreventive, antioxidant and neuroprotective effects. In this study, we showed that celastrol inhibits inflammatory reactions in macrophages and protects mice from skin inflammation. MATERIALS AND METHODS Anti-inflammatory effects of celastrol (0-1 microM) were examined in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. To investigate the effects of celastrol (0-50 microg per mice) in vivo, activation of myeloperoxidase (MPO) and histological assessment were examined in the 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced mouse ear oedema model. RESULTS Our in vitro experiments showed that celastrol suppressed not only LPS-stimulated generation of nitric oxide and prostaglandin E(2), but also expression of inducible nitric oxide synthase and cyclooxygenase-2 in RAW264.7 cells. Similarly, celastrol inhibited LPS-induced production of inflammatory cytokines, including tumour necrosis factor-alpha and interleukin-6. In an animal model, celastrol protected mice from TPA-induced ear oedema, possibly by inhibiting MPO activity and production of inflammatory cytokines. CONCLUSIONS Our data suggest that celastrol inhibits the production of inflammatory mediators and is a potential target for the treatment of various inflammatory diseases.
