Purpose Watermelon (Citrullus lanatus) fruit and its rind are known to contain phytochemicals that may have health benefits. The aim of this paper is to investigate the potential hypocholesterolemic effect of watermelon fruit rind (WR) using rats who are fed a high-cholesterol diet. Design/methodology/approach Rats were divided into six groups and fed diets for eight weeks containing normal control diet or normal control diet with either 1% cholesterol, 5% WR, 10% WR, 1% cholesterol + 5% WR or 1% cholesterol + 10% WR. Triglycerides, total cholesterol and lipoprotein levels in serum and liver samples were determined, and histopathological examination of liver tissues was carried out. Findings Diets containing 1% cholesterol led to hypercholesterolemia, characterized by increased levels of total cholesterol and low-density lipoproteins in rat serum and liver samples. Incorporation of 10% WR into the diet of the otherwise hypercholesterolemic rats led to significant reduction in serum levels of total cholesterol (from 266.2 to 222.7 mg/dL) and low-density lipoproteins (from 159.5 to 94.4 mg/dL). In addition, these rats also exhibited improvements in hepatic tissue structure compared to the hypercholesterolemic rats. Originality/value These results support the potential use of WR as a hypocholesterolemic agent. Further research is needed to ascertain the hypocholesterolemic effect of WR in human.

For the treatment of familial hypercholesterolemia, Liposorber LA-40 was clinically applied. The Liposorber is a commercially developed affinity adsorbent for plasma perfusion which selectivily adsorbs low density lipoproteins and very low density lipoproteins and is specially designed for plasmapheretic treatment of hypercholesterolemia. The Liposorber column, containing activated cellulose beads having an affinity for liporpotein containing apolipoprotein-B, has an excellent adsorption capacity, excellent selectivity, minimum albumin loss. This new apheresis system was applied to 2 clinical cases. After seven months of trial perfusion every 2 weeks, patient condition was good, with a level of total cholesterol under 300 mg/dl. No replacement fluids were given during or after treatment. In this paper, clinical results of these patients were shown and the mechanism of adsorption of this specific adsorbent was discussed.

Objective To evaluate the effects of walking, independent of diet and weight-loss, on lipids and lipoproteins in women with overweight and obesity. Data Source Academic Search Complete, Alternative Health Watch, Global Health, Health Source, CINAHL, MEDLINE, EMBASE, SportDiscus, and ProQuest. Study Inclusion and Exclusion Criteria (1) experiment-control design; (2) women with overweight or obesity; (3) walking as the experiment’s independent variable; (4) four or more weeks; and (5) pre- to post-assessment of lipids and/or lipoproteins. Excluded studies reported use of lipid-lowering medication, diet or other modes of physical activity, and alternative interventions as the control. Data Extraction Data extraction and study quality were completed by the first 2 authors using the Cochrane review protocol and risk of bias assessment. Data Synthesis Raw mean difference between the experiment and control groups using a random effects model. Results Meta-analyses of 21 interventions (N = 1129) demonstrated exclusive walking improves total cholesterol (raw mean difference = 6.67 mg/dL, P = .04) and low-density lipoproteins (raw mean difference = 7.38 mg/dL, P = .04). Greater improvement in total cholesterol, triglycerides, high-density lipoproteins, and low-density lipoproteins existed in women with obesity. Conclusions Exclusive walking aids in normalizing total cholesterol and LDLs in women with overweight and obesity. Exclusive walking can be used as a non-pharmacologic therapy, which may have positive clinical outcomes for individuals who especially struggle with diet and weight-reduction.

Purpose This study aims to examine whether Globularia alypum (Ga) lyophilized aqueous leaves extract treatment improves cardiometabolic syndromes such as hyperglycemia, lipid profiles and oxidative damage resulting from a high-fructose diet induced in hypertriglyceridemic rats. Design/methodology/approach A total of 24 male Wistar rats weighing 80 ± 5 g were first randomly divided into 2 groups. A total of 12 control rats (C) were fed a standard-diet (St-D) and 12 high fructose (HF) rats were fed a high-fructose diet (HF-D) containing St-D in which cornstarch was substituted by fructose (61.4%). After 15 weeks of feeding, body weight (BW) was about 320 ± 20 g and hypertriglyceridemia was noted in HF vs C group (2.69 ± 0.49 mmol/L) vs (1.25 ± 0.33 mmol/L). Each group of rats was then divided into two equal groups (n = 6) and fed during four weeks either a St-D or HF-D, treated or not with 1% of Ga extract (C-Ga) and (HF-Ga). After 28 days, fasting rats were anesthetized and blood and tissues were removed to measure biochemical parameters. Findings The results showed no significant differences in BW and insulinemia between all groups. Ga extract supplementation reduced glycemia (−36%), glycosylated hemoglobin (−37%), Homeostasis Model of Assessment-Insulin Resistance index (−34%) and triacylglycerol’s contents in plasma (−33%), very low density lipoproteins–low density lipoproteins (VLDL-LDL) (−48%), liver (−52%) and aorta (−39%); total cholesterol concentrations in aorta was 3.7-fold lower in HF-Ga vs HF group. Ga treatment reduced lipid peroxidation in plasma, VLDL-LDL, red blood cells (RBC), liver, muscle and kidney by improving superoxide dismutase (SOD) activity and glutathione peroxidase (GPx) in RBC and catalase (CAT) activity in kidney (p < 0.05). Moreover, Ga ameliorates glutathione (GSH) production in RBC (+41%) and kidney tissues (+35%). Originality/value Ga extract ameliorated cardiometabolic syndrome by its hypotriglyceridemic effect and prevented development of insulin resistance. It reduces lipid peroxidation by enhancing non-enzymatic (GSH) and enzymatic (SOD, GPx and CAT) antioxidant defense systems in high-fructose hypertriglyceridemic rats. Therefore, supplementation of Ga leaves extract as an adjuvant could be used for the treatment of hypertriglyceridemia and the prevention and/or the management of cardio-metabolic adverse effects.

The purpose of this study was to determine if the U.S. National Institutes of Health Diabetes Prevention Program (DPP) could be successfully implemented in a worksite setting. Thirty-seven adult employees of BD Medical Systems of Sandy, Utah were enrolled in a single-group time-series study using the DPP. Two-hour oral glucose tolerance tests (OGTT) and other outcomes were measured at baseline, 6 months, and 12 months. Weight, body mass index, waist circumference, 2-hour OGTT, very low density lipoproteins, triglycerides, and aerobic fitness were significantly improved at 6 and 12 months and showed overall significant improvement across time. Fasting blood insulin, total cholesterol, low density lipoproteins, and total cholesterol/high density lipoproteins ratio were significantly improved at 6 months, but not at 12 months. Eighteen of the program participants (51%) were no longer in the pre-diabetes and diabetes categories after 1 year. Existing worksite health promotion and occupational health professionals can successfully offer the DPP and help employees improve glucose tolerance.

Background. Changes in lipid metabolism indicators in the pre- and postoperative periods are due to frequent metabolic disorders in obese people and particular difficulties with the selection of appropriate therapy. In turn, the cause for metabolic changes in the body is the influence of a certain extreme situation — surgical intervention. Objective: to study the changes in lipid metabolism in the pre- and postoperative periods in obese patients with laparoscopic cholecystectomy. Materials and methods. The study involved 50 individuals (mean age — 47.0 ± 1.5 years), who underwent surgery for acute cholecystitis by laparoscopic cholecystectomy. The patients were divided into 2 groups: 1 — obese, 2 — non-obese. The level of triglycerides, total cholesterol, high-density lipoproteins (HDL), low-density lipoproteins (LDL), very-low-density lipoproteins (VLDL) was assessed in all patients and compared in the preoperative period and on days 1 and 5 after surgery. Results. The parameters of lipid metabolism in the pre- and postoperative periods in all groups had permissible fluctuations, given the fact that in obese patients lipids were initially increased compared to patients without obesity. In the postoperative period in group 1 on the first day, there was a decrease in triglycerides (1.1 ± 0.6 mmol/L) from the baseline, in total cholesterol (4.5 ± 0.3 mmol/L), an increase in HDL cholesterol (1.5 ± 0.2 mmol/L), a decrease in LDL (2.9 ± 0.2 mmol/L) and VLDL (1.0 ± 0.2 mmol/L). In group 2, indicators of triglyceri­des (0.6 ± 0.2 mmol/L), total cholesterol (3.4 ± 0.1 mmol/L), LDL (1.9 ± 0.3 mmol/L) and VLDL (0.8 ± 0.2 mmol/L) also tended to decrease and there was an increase in HDL (1.6 ± 0.1 mmol/L), but these values, regardless of their variation, were within the normal range. In group 1, three patients showed cognitive impairment, which was due to a significant increase in LDL over HDL and the possible development of atherosclerosis, which could lead to cerebrovascular accident. Conclusions. After conducting a study between two groups in which the lipids were studied, a variation in parame­ters was revealed in both groups, which is due to the characteristics of metabolism in such patients and the influence of surgical stress. Based on this, control and regulation of lipid values should be carried out in all patients with dyslipidemia, and in obese patients, additional consideration should be given to risk factors, concomitant diseases and possible complications.

Objective: study sesquiterpene lactones grosshemin and grossmisin lipid-lowering properties on the model of acute hyperlipidemia induced by ethanol in rats.Materials and methods. Rats during 7 days injected into the stomach grosshemin and grossmisin in a dose 10 mg/kg or reference drug nicotinic acid in a dose 25 mg/kg. Hyperlipidemia caused by single introduction of ethanol into the stomach in a dose 5 g/kg. In blood serum of tail vein measured the triacylglycerols, total cholesterol, high density and low density lipoproteins cholesterol, also the level of free fatty acids. Calculated the ratio of high density lipoproteins cholesterol to the amount of low density lipoproteins cholesterol and the index of atherogenicity.Results. A single dose of ethanol increased serum level of triacylglycerols in 1.9 times, free fatty acids – in 3.2 times, low density lipoproteins – on 44% in comparison with the intact animals indices. It shows the development of acute hyperlipidemia. Serum total cholesterol, high density lipoproteins cholesterol and the index of atherogenicity were not changed. Course sesquiterpene lactones grosshemin and grossmisin introduction against the background of acute hyperlipidemia was accompanied by a decrease in the serum of triacylglycerols levels respectively by 19.8% and 34.1%. Nicotinic acid lowered the content of triacylglycerols by 42.4%. Grosshemin and nicotinic acid reduced the increased level of free fatty acids in the blood serum by 60.7–67.9%. Grossmisin and nicotinic acid decreased by 14.6–17.2% of total cholesterol in the blood serum. In acute hyperlipidemia grosshemin and grossmisin reduced low density lipoproteins cholesterol by 17.6% and 20%, respectively, nicotinic acid – by 15.7%. Both of sesquiterpene lactone and nicotinic acid did not modify the content of high density lipoproteins cholesterol. When introduction grosshemin, grossmisin and nicotinic acid ratio of high density lipoproteins cholesterol to the amount of low density lipoproteins cholesterol significantly increased by 42.8%, 38,6% and 22.1% respectively.Conclusion. Sesquiterpene lactones grosshemin and grossmisin posses hypolipidemic effect in acute experimental hyperlipidemia caused by the ethanol introduction. Lactones normalize many indices of lipid metabolism, which can be caused by different biochemical targets of these molecules. Lactones, as nicotinic acid, in the model of acute hyperlipidemia decrease in blood serum triacylglycerols, total cholesterol, and low density lipoproteins cholesterol content. Grosshemin and nicotinic acid also reduce the free fatty acids level.

Genomic prediction using multi-allelic haplotype models improved the prediction accuracy for all seven human phenotypes, the normality transformed high density lipoproteins, low density lipoproteins, total cholesterol, triglycerides, weight, and the original height and body mass index without normality transformation. Eight SNP sets with 40,941-380,705 SNPs were evaluated. The increase in prediction accuracy due to haplotypes was 1.86-8.12%. Haplotypes using fixed chromosome distances had the best prediction accuracy for four phenotypes, fixed number of SNPs for two phenotypes, and gene-based haplotypes for high density lipoproteins and height (tied for best). Haplotypes of coding genes were more accurate than haplotypes of all autosome genes that included both coding and noncoding genes for triglycerides and weight, and nearly the same as haplotypes of all autosome genes for the other phenotypes. Haplotypes of noncoding genes (mostly lncRNAs) only improved the prediction accuracy over the SNP models for high density lipoproteins, total cholesterol, and height. ChIP-seq haplotypes had better prediction accuracy than gene-based haplotypes for total cholesterol, body mass index and low density lipoproteins. The accuracy of ChIP-seq haplotypes was most striking for low density lipoproteins, where all four haplotype models with ChIP-seq haplotypes had similarly high prediction accuracy over the best prediction model with gene-based haplotypes. Haplotype epistasis was shown to be the reason for the increased accuracy due to haplotypes. Low density lipoproteins had the largest haplotype epistasis heritability that explained 14.70% of the phenotypic variance and was 31.27% of the SNP additive heritability, and the largest increase in prediction accuracy relative to the best SNP model (8.12%). Relative to the SNP additive heritability of the same regions, noncoding genes had the highest haplotype epistasis heritability, followed by coding genes and ChIP-seq for the seven phenotypes. SNP and haplotype heritability profiles showed that the integration of SNP and haplotype additive values compensated the weakness of haplotypes in estimating SNP heritabilities for four phenotypes, whereas models with haplotype additive values fully accounted for SNP additive values for three phenotypes. These results showed that haplotype analysis can be a method to utilize functional and structural genomic information to improve the accuracy of genomic prediction.

<p>In recent years, functional foods have attracted much interest to prevent nutrition-related diseases such as hyperlipidemia and weight gain. In this regard, this study was designed to examine the effect of use sweet white lupin (SWL) oil and flour with/without germination as a source of active healthy components to prepare functional biscuits for lowering blood lipids and growth. Functional biscuits were formulated by replacing wheat flour and butter in biscuit formulae by SWL extracted flour and SWL oil in the range of 20-30% (w/w) and 30-40% (v/w), respectively. Results indicated that the feed of hyperlipidemic rats on diets supplemented with different functional SWL biscuits for 6 weeks significantly (P &lt; 0.05) reduced serum total cholesterol, triglycerides, low density lipoproteins, very low density lipoproteins, ratio of total cholesterol/high density lipoproteins cholesterol, ratio of low density lipoproteins/high density lipoproteins cholesterol and atherogenic index. Furthermore, the feed of functional SWL biscuits significantly reduced the body weight gain of rats and their food efficiency compared to that of rats fed on hyperlipidemic diet. On the other hand, there was an increase in the value of high density lipoproteins cholesterol and its ratio with total cholesterol. All these findings supported that the addition of 25% germinated SWL flour and 35% or 40% germinated SWL oil in biscuits gave interested results compared to the common wheat biscuits. Therefore, the proposed functional SWL biscuits could be able to regulate the blood cholesterol and the body growth levels of individuals and patients.</p>

Cholesteryl ester transfer protein gene contains some single nucleotide polymorphisms, which have been associated with serum high-density lipoprotein concentration and other lipoproteins. This study is done for determining of cholesteryl ester transfer protein polymorphism and evaluate its effect on serum lipid profile concentrations in some hyperlipidemic patients compared with healthy subjects in Salah Al-din governorate-Iraq. Blood samples were taken from (90) patients suffering from hyperlipidemia, and (70) samples that were apparently healthy controls.  Serum lipid concentrations were measured by enzymatic assays. The polymorphism was genotyped using polymerase chain reaction restriction fragment length polymorphism analysis.  The results showed that there was a significant decrease (P<0.05) in the frequency B2 allele, and B1B2, B2B2 genotype, and a significant increase (P<0.05) in the frequency B1 allele, and B1B1 genotype between patients and controls groups. There was a non-significant decrease in the levels of high density lipoproteins, total cholesterol, low density lipoproteins, and very low density lipoproteins levels, and non-significant increase in levels of triglycerides in individuals with the B1B1 genotype than in the B1B2 and B2B2 genotype. However, high density lipoproteins showed a significant decrease (P<0.001) between individuals with the B1B1 genotype and B2B2 genotype. Also, there was a non-significant difference in the levels of high density lipoproteins, total cholesterol, low density lipoproteins, and very low density lipoproteins levels, in individuals with the B1B2 genotype when compared with that of the B2B2 genotype.
