Abstract Background Vaccinium myrtillus leaves are known to be rich in phenols and have been used in traditional medicine as an antidiabetic remedy. This study evaluated the powder extract of V. myrtillus leaves obtained with the use of L-arginine and myo-inositol for anti-obesity and lipid-lowering potential in hamsters. Methods Standard phytochemical methods were used to determine the total phenolic and total flavonoid contents of the extract. The obesity condition was induced in Syrian hamsters by feeding them with highly palatable fat- and sugar-rich diet (40.3 kcal% fat) for 12 weeks. From the 10th week of diet feeding, the obese hamsters were treated with the powder extract of V. myrtillus leaves (15, 25 and 35 mg/kg/day, respectively) and “Styfimol” (6.2 mg/kg/day of hydroxycitric acid) as a positive control drug. At the end of the treatment period, the biochemical parameters as well as visceral fat mass were determined. Results Vaccinium myrtillus leaves powder extract at 25 and 35 mg/kg/day caused a significant reduction in body weight gain and visceral fat mass in obese hamsters. Serum triacylglycerols, free fatty acids, total cholesterol and low-density lipoprotein cholesterol (LDL-C) levels were also significantly lower. Besides, the hamsters treated with powder extract at 25 and 35 mg/kg/day had the closest intact value ratio of high-density lipoprotein cholesterol and LDL-C compared with positive control animals. Conclusions The results showed that V. myrtillus leaves powder extract is a promising therapeutic agent for the treatment of obesity and obesity-induced diseases.

Abstract Background Chatuphalatika is a Thai traditional health tonic composing of four different herbs namely Terminalia bellerica Linn., T. chebula Retz., T. arjuna Roxb. and Phyllanthus emblica Linn. The fact that phytoconstituents of Terminalia species have been reported to ameliorate obesity and symptoms of metabolic syndrome prompt us to investigate acute toxicity as well as a lipid lowering activity of orally given chatuphalatika aqueous extract (CPT) in animal models. Methods CPT was prepared by decoction method and the phytochemical contents were quantified by HPLC analysis. The acute oral toxicity study of CPT was performed in Wistar rats following the protocol of the Organisation for Economic Co-operation and Development (OECD) guidelines No. 420. The assessment of lipid-lowering effect of CPT was carried out in high-fat diet (HFD) fed C57BL/6 mice model. Results Gallic acid was the highest content (137.10 ± 5.42 mg/g) found in CPT followed by chebulinic acid (73.60 ± 2.35 mg/g), chebulagic acid (62.60 ± 4.17 mg/g) and ellagic acid (5.2 ± 0.40 mg/g). No lethality and no signs of toxicity were observed in either male or female rats orally treated with CPT at a single dose of 2,000 and 5,000 mg/kg. Daily oral administration of 250, 500 or 1,000 mg/kg of CPT for 6 weeks to the HFD-induced dyslipidemia mice markedly reduced low density lipoprotein cholesterol (LDL-C) levels and increased high density lipoprotein cholesterol (HDL-C) levels, whereas the significant reduction of total cholesterol (TC) levels was observed only in the high doses of 500 and 1,000 mg/kg of CPT. Moreover, dyslipidemia mice received 1,000 mg/kg CPT exclusively showed the decrease in body weight gain. Conclusions The CPT was safe and effective for relieving dyslipidemia and reducing weight gain in animal model supporting further development as functional food for dyslipidemia or overweight population.

Five novel derivatives of N-(9,10-dihydro-9,10-dioxoanthracenyl)-1H-indole-2-carboxamide were synthesized and their lipid-lowering effects studied in hyperlipidemic rats. Fusion of the anthraquinone derivatives at high temperature with 5-indole-2-carbonyl chloride, followed by recrystallization from chloroform=methanol gave the desired compounds in excellent yields. Compounds 1 to 5 at a non-toxic dose (1 ml of 57 mM solutions) and bezafibrate as positive control were administered to rats that were hyperlipidemic due to treatment with Triton WR-1339. A decrease in the plasma levels of triglyceride (TG) and low-density lipoprotein-cholesterol (LDL-C) and an increase in the plasma level of high-density lipoprotein-cholesterol (HDL-C) were observed with compounds 1, 3, 4, and 5. Compounds 1, 4, and 5 significantly reduced total cholesterol (TC) levels as well. These compounds may provide agents for targeting dyslipidemia and cardiovascular disease.

Background: The associations of triglyceride (TG) to high-density lipoprotein cholesterol ratio (HDL‑C) and total cholesterol (TC) to HDL‑C ratio and low ankle brachial index (ABI) were seldom investigated. Patients and methods: A population based cross-sectional survey was conducted and 2982 participants 60 years and over were recruited. TG, TC, HDL‑C, and low-density lipoprotein cholesterol (LDL-C) were assessed in all participants. Low ABI was defined as ABI ≤ 0.9 in either leg. Multiple logistic regression models were applied to study the association between TG/HDL‑C ratio, TC/HDL‑C ratio and low ABI. Results: The TG/HDL‑C ratios for those with ABI > 0.9 and ABI ≤ 0.9 were 1.28 ± 1.20 and 1.48 ± 1.13 (P < 0.0001), while the TC/HDL‑C ratios were 3.96 ± 1.09 and 4.32 ± 1.15 (P < 0.0001), respectively. After adjusting for age, gender, body mass index, obesity, current drinking, physical activity, hypertension, diabetes, lipid-lowering drugs, and cardiovascular disease history, the odds ratios (ORs) with 95 % confidence intervals (CIs) of low ABI for TG/HDL‑C ratio and TC/HDL‑C ratio were 1.10 (0.96, 1.26) and 1.34 (1.14, 1.59) in non-smokers. When TC was further adjusted, the ORs (95 % CIs) were 1.40 (0.79, 2.52) and 1.53 (1.21, 1.93) for TG/HDL‑C ratio and TC/HDL‑C ratio, respectively. Non-linear relationships were detected between TG/HDL‑C ratio and TC/HDL‑C ratio and low ABI in both smokers and non-smokers. Conclusions: TC/HDL‑C ratio was significantly associated with low ABI in non-smokers and the association was independent of TC, TG, HDL‑C, and LDL-C. TC/HDL‑C might be considered as a potential biomarker for early peripheral arterial disease screening.

Abstract Introduction High prevalence of cardiovascular events at northern latitudes determines the necessity of studying mechanisms of formation and early diagnosis of atherosclerotic process. Purpose To determine the most unfavorable prognostic factors that provide the percentage of correct prediction and high accuracy in detection of atherosclerotic plaque (ASP) in common carotid arteries (CCA) in rotational shift workers in the Arctic. Methods Within 2010–2012 a study of 424 males aged 30–59 years at the medical unit “Gazprom dobycha Yamburg” (Yamburg settlement, 68°N) was performed. Patients were randomized into 2 groups according to blood pressure (BP). Gr.I included 294 people with BP more than 140/90 mmHg, arterial hypertension (AH) of 1,2 stage and Gr.II included 130 people with BP less than 140/90 mmHg. Groups did not differ in age (46.9±5.8 years, p=0.435); total work experience in the Arctic: 16.5±6.8 years (p=0.512) and rotational shiftwork duration: 12.5±4.6 years (p=0.597). Office BP was 149.4±13.3/97.1±7.3 mmHg in Gr.I and 123.4±7.5/80.5±5.5 mmHg in Gr.II. Ultrasound examination of carotid arteries with determination of presence or absence of ASP in CCA and estimation of stenosis using NASCET method were performed; ambulatory blood pressure monitoring was conducted; blood glucose levels, total cholesterol, high-density lipoprotein cholesterol, low density lipoprotein cholesterol were determined. Statistical analysis was carried out using R (v. 3.6.1) programming language for statistical data processing of R Studio application package (v. 1.2.1335). Results Signs of CCA atherosclerosis were revealed in 56% of patients with AH and in 25% of those without AH. According to multivariate analysis, three variables with the most significant set of predictors, associated with ASP in CCA with the percentage of correct prediction of 75.9% were selected by step-by-step method: diastolic BP24 (&lt;0.0001), glucose (0.0167) and cholesterol (0.0439). Based on the obtained model, it was concluded that 1 mmHg increase in diastolic BP24 increases the risk for developing ASP by 5.9%, Exp. (Beta) = 1.059, 1 mmol/l increase in glucose and cholesterol escalates the risk by 44.1% and 25.2%, respectively: Exp. (Beta) = 1.441 and Exp. (Beta) = 1.252. Conclusion The data obtained will improve accuracy for the early diagnosis of subclinical atherosclerosis of CCA, allow to prescribe lipid-lowering therapy timely and reduce the risk of adverse cardiovascular events in rotational shift workers in the Arctic.

AbstractSeveral studies have shown that rs9939609 and rs1421085 in fat mass and obesity-associated (FTO) gene rs17782313 and rs12970134 in melanocortin-4 receptor (MC4R) gene influence obesity. In the present study, we aimed to determine association between rs9939609, rs1421085, rs17782313, and rs12970134 polymorphism, and their relation with body mass index (BMI), glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR) and lipid values in obese children. We included 100 newly diagnosed obese children and 100 healthy children. The rs1421085 (CC/CT) (p = 0.019) and rs9939609 (AA/AT) (p = 0.002) polymorphism regions were higher in the obese group. Additionally, we found that both the rs1421085 (CC/CT) and rs9939609 (AA/AT) polymorphism associated with high-density lipoprotein cholesterol (p = 0.011 and p = 0.003) and triglycerides (p = 0.01 and p = 0.004) level, respectively. Further, the rs9939609 and rs1421085 variants of FTO gene associated with HDL-cholesterol and triglycerides levels in obese children; however, updated studies with a large sample size are required to establish strong links with genetic variants and risk factors in childhood obesity.

Objective: Hyperlipidemia is one of the risk factors that contribute to the prevalence of coronary heart diseases and antihyperlipidemic agents, such as statin, was used to treat hyperlipidemia as a current therapy. Boesenbergia pandurata has not been exploited for antihyperlipidemic effect. Hence, this study aims to screen for the antihyperlipidemic activity of methanolic extracts of B. pandurata rhizomes (BPR extracts) in hypercholesterolemia-induced Sprague-Dawley rats.Methods: BPR extracts were prepared using the maceration method with 1500 ml of 80% methanol at room temperature for about 7 days. A toxicity study was carried out based on OECD guidelines. Hypercholesterolemia was induced by 6% lard oil, 2% of cheese, and egg yolks. Two different doses of BPR extracts, 200 and 400 mg/kg, were used to screen for antihyperlipidemic effect. Histopathological study was carried out in the liver. The results were evaluated for the statistically significant difference by using the one-way ANOVA followed by post hoc Dunnett test.Results: No mortality was witnessed even till 2 g/kg. Only 400 mg/kg of BPR extracts statistically reduced in total cholesterol (p<0.05), low-density lipoprotein-cholesterol (p<0.05) and an increase in high-density lipoprotein-cholesterol (p<0.05) when compared to the positive control. BPR extracts (400 mg/kg) showed less enlargement of lipid droplets as compared to positive control.Conclusion: BPR extracts can be a promising medicinal plant for treating hyperlipidemia in underdeveloped countries.

Background. Central arterial stiffness is a surrogate of cardiovascular risk and predicts cardiovascular mortality. Apolipoprotein B lipoproteins are also established cardiovascular risk factors. It is not known whether specific lipoprotein subclasses measured in the Malmö Diet and Cancer Study and previously shown to be associated with coronary heart disease also predict arterial stiffening after a mean period of 17 years. Methods. Lipoprotein particle analysis was performed on 2,505 men and women from Malmö, Sweden, from 1991 to 1994, and arterial stiffness was assessed by carotid-femoral pulse wave velocity (c-fPWV) on this same cohort from 2007 to 2012. Associations between c-fPWV and lipoprotein particles were determined with multiple linear regression, controlling for sex, presence of diabetes, waist-to-hip circumference, and smoking status at baseline, as well as heart rate (measured at the carotid artery), mean arterial pressure, antihypertensive and lipid-lowering medications, C-reactive protein (CRP), and age at the time of c-fPWV measurement. Results. The results confirm that triglycerides (TG) and high-density lipoprotein cholesterol (HDL-c) but not low-density lipoprotein cholesterol (LDL-c) predict c-fPWV. We identify a positive predictive association for very small, small, and medium (high risk), but not large LDL particles. There was a negative association for large HDL particles. The relationships between c-fPWV and high-risk LDL particles were unaffected by adjusting for LDL-c or CRP and were only mildly attenuated by adjusting for the homeostatic model for insulin resistance (HOMA-IR). Due to the collinearity of very small, small, and medium LDL particles and dyslipidemia (elevated TG and decreased HDL-c), the observed relationship between c-fPWV and high-risk LDL particles became insignificant after controlling for the concentration of HDL-c, large cholesterol-rich HDL particles, and TG. Conclusions. The development of central arterial stiffness previously associated with combined dyslipidemia may be mediated in part by LDL particles, particularly the very small-, small-, and medium-sized LDL particles.

Diabetes mellitus (DM) is a serious chronic metabolic disorder. Various diseases are being treated with medicinal plants and that is because of the less side effects of the current therapy. The diversity of plants in Armenia is due to the singularity of natural environment. However, biochemical activity of these plants has not been studied well. Thus, the goal was to investigate biochemical activity and antihyperglycemic properties ofRumex obtusifoliusL. in rabbits with hyperglycemia. The high content of total phenolic compounds, flavonoids, and tannins has been determined in this plant extract. Oral administration of ethanol extract showed significant effect on hyperglycemia, reducing fasting glucose levels (57.3%, p<0.05), improving glucose tolerance, and increasing liver glycogen content (1.5-fold, p<0.01) compared to the hyperglycemic control group. Furthermore, ethanol extract ofR. obtusifoliusreduced total cholesterol, low-density lipoprotein cholesterol levels, and vice versa increased high-density lipoprotein cholesterol levels and also decreased liver enzymes levels (alanine aminotransferase and aspartate aminotransferase) compared with untreated group. These findings suggest thatR. obtusifoliusmay have beneficial effects and should be supplement, as herbal remedy in the treatment of DM.

Low-density lipoprotein cholesterol (LDL-C) is a well-known risk factor for coronary heart disease but protects against infection and sepsis. We aimed to disclose the exact association between LDL-C and severe 2019 novel coronavirus disease (COVID-19). Baseline data were retrospectively collected for 601 non-severe COVID-19 patients from two centers in Guangzhou and one center in Shenzhen, and patients on admission were medically observed for at least 15 days to determine the final outcome, including the non-severe group (n = 460) and the severe group (severe and critical cases) (n = 141). Among 601 cases, 76 (12.65%) received lipid-lowering therapy; the proportion of patients taking lipid-lowering drugs in the severe group was higher than that in the non-severe group (22.7 vs. 9.6%). We found a U-shaped association between LDL-C level and risk of severe COVID-19 using restricted cubic splines. Using univariate logistic regression analysis, odds ratios for severe COVID-19 for patients with LDL-C ≤1.6 mmol/L (61.9 mg/dL) and above 3.4 mmol/L (131.4 mg/dL) were 2.29 (95% confidence interval 1.12–4.68; p = 0.023) and 2.02 (1.04–3.94; p = 0.039), respectively, compared to those with LDL-C of 2.81–3.40 mmol/L (108.6–131.4 mg/dL); following multifactorial adjustment, odds ratios were 2.61 (1.07–6.37; p = 0.035) and 2.36 (1.09–5.14; p = 0.030). Similar results were yielded using 0.3 and 0.5 mmol/L categories of LDL-C and sensitivity analyses. Both low and high LDL-C levels were significantly associated with higher risk of severe COVID-19. Although our findings do not necessarily imply causality, they suggest that clinicians should pay more attention to lipid-lowering therapy in COVID-19 patients to improve clinical prognosis.
