Purpose: To investigate the effects of oral atorvastatin on spermatogenesis in a rat model.Methods: Rats were equally assigned into control and study groups, the latter receiving atorvastatin (20 mg/kg/day). At the end of 12 weeks, spermatogenetic activity was evaluated using stereological and optical fractionator methods. Serum follicle-stimulating hormone (FSH), total testosterone (TT), and luteinizing hormone (LH) levels were measured using micro–ELISA kits. Total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL - C), and high-density lipoprotein cholesterol levels were also measured by enzymatic colorimetric assays.Results: Testicular stereological analysis revealed that atorvastatin reduced Sertoli cell numbers (p < 0.001), spermatogonia (p < 0.001), spermatocytes (p < 0.001), and seminiferous tubule diameters (p < 0.001). LDL – C (p = 0.01) and TG (p = 0.01) values were significantly lower in the study group compared with the control group. There was no significant difference in FSH (p = 0.44), LH (p = 0.48),and TT (p = 0.06) levels between the groups.Conclusion: The findings show that atorvastatin causes deleterious effects on rat spermatogenesis. It should therefore be used with caution in clinical practice owing to its potential adverse effects, especially on male fertility.

The metabolic fitness (MF) is a component of athletes’ physical conditioning. This study aims to investigate the effects of quercetin supplementation on Turkish Junior athletes’ lipid and protein metabolism relating to MF after one month classic boxing training. Totally 20 voluntary junior male athletes were separated into two equal groups as the experimental group (EG) and control group (CG). The participants were supplemented with 500 mg quercetin fifteen minutes before each workout in one month boxing training program. Blood samples during pre and post training were taken from athletes in order to determine metabolic fitness related parameters. Lipid profile contains low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), trigliserid (TG), total cholesterol (TC) variables while protein metabolism includes the albumin, total protein, direct bilirubin and total bilirubin parameters. The Mann Whitney U analyzes were used for comparison of the means between experimental and control groups during pre and posttest and between pre and post test results in experimental and control groups. This study showed that EG had a similar physical characteristic with CG. There were significant decrease in TC and LDL-C and an increase in HDL-C in EG while there was only significant increase in HDL-C of in controls. A significant difference of HDL-C was observed between EG and CG during pretest. In other side, TC and LDL-C and HDL-C were significantly differentiated between EG and CG during posttest. Conclusion: it can be concluded that quercetin plays an important role on lipid metabolism not protein.

Abstract Introduction: Throughout normal pregnancy, different metabolic and hormonal adaptations are presented, among others, significant modifications in the profile of lipids and lipoprotein metabolism. On the other hands, Angiopoietin-like protein 3 (ANGPTL3) are involved in the regulation of triglyceride metabolism in the fed state by inhibiting the enzyme lipoprotein lipase in oxidative tissues. Objective: Thus, the objective of this study was to determine the profile of serum ANGPTL3 levels during three periods of gestation and three months after delivery. Design, setting and Participants: Serum ANGPTL3 levels were analyzed by ELISA, throughout pregnancy in a case-control study nested within a longitudinal prospective cohort of healthy pregnant (n = 52) and mild preeclamptic women (n = 20), women in the third month postpartum (n = 20) and healthy non-pregnant women (n = 20). The results obtained were correlated with biochemical, hormonal, and anthropometric variables. Results: A significant reduction in ANGPTL3 levels was observed from the first to the third trimesters of pregnancy in healthy and preeclamptic pregnant women when compared with healthy non-pregnant and postpartum women (p&lt;0.01). There were no significant differences in serum ANGPTL3 levels between normal and preeclamptic women. Serum ANGPTL3 levels were positively correlated with triglyceride, very-low-density lipoprotein cholesterol, and total cholesterol levels in healthy non-pregnant (p&lt;0.05); whereas there were no significant correlations between ANGPTL3 with the same variables in healthy and preeclamptic pregnant women. Besides, there were no significant correlations between serum ANGPTL3 with body mass index, high-density lipoprotein cholesterol, glucose, insulin, leptin or HOMA-IR in the study groups described above. Conclusions: The results of the present study show for the first time that ANGPTL3 could be playing a fundamental role in the homeostasis of lipid metabolism throughout gestation. Thus, low levels of ANGPTL3 during pregnancy might favor the accumulation of lipid in oxidative tissues as a deposit of maternal energy source, while preserving glucose and amino acids for the fetus.

Abstract Low cholesterol levels can be detected in solid tumors and hematological malignancies such as muliple myeloma. Moreover chloesterol levels reduced in some experimental studies of patients with chronic lymphocytic leukemia (CLL). In this retrospective multicenter study, lipid levels were retrospectively evaluated in 420 (264 male and 256 female with mean age 64 ± 11 years) patients with newly diagnosed CLL, according to the International CLL study group. 71 (28 male and 43 female with mean age 55 ± 9 years) healthy subjects as control group were included to this study. Lipid parameters such as total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), very low-density lipoprotein-cholesterol (VLDL-C), and triglyceride levels were measured with enzymatic/ calorimetric method and Architect C800 instrument. Low-density lipoprotein-cholesterol (LDL-C) levels were calculated according to Friedwald formula. Lipid parameters between two groups were compared with Mann-Whitney U test. A value of p< 0.05 was accepted as statistically significant. According to Binet classification, 60% of patients were in stage A, while 25% of them were in stage C. In CLL patients, the levels of TC, HDL-C, and LDL-C were lower than those of control group (p=0.001). There was no significantly difference for triglyceride and VLDL-C levels between two groups (p>0.05) (Table-1). The levels of TC, LDL-C, and HDL-C in the patients with stage C were lower than those of both stage A and stage B (Table-2). Low cholesterol levels in patients with CLL may occur due to increased use of cholesterol by lymphocytes.Table-1Lipid parameters in control group and CLL patientsCLL (N:420)Control (N:71)P valueTC (mg/dl)175±41217±36<0.001HDL-C (mg/dl)37±1153±14<0.001LDL-C (mg/dl)108±30131±29<0.001Triglyceride (mg/dl)140±71147±68>0.05VLDL-C (mg/dl)31±1731±17>0.05Table 2Lipid parameters in the patients according to Binet classificationStage A (n:255)Stage B(n:61)Stage C(n:104)P valueTC(mg/dl)183±38179±43156±40<0.001HDL-C(mg/dl)40±1237±1232±12<0.001LDL-C (mg/dl)112±28110±3398±30<0.001Triglyceride (mg/dl)141±76136±53141±68>0.05VLDL-C(mg/dl)30±1535±3331±13>0.05 Disclosures: Sonmez: Novartis Pharmaceuticals Corporation, Turkey: Membership on an entity’s Board of Directors or advisory committees.

Aim Limited cardiovascular disease (CVD) risk data are available for firefighters worldwide. This comparative study was aimed at investigating the biochemical and nutritional indices of firefighters in Iran. Materials and methods Individuals’ anthropometric measurements, including weight, height, and waist and hip circumferences, were measured and the percent of body fat (BF%) was also obtained. Blood sampling was done in order to determine lipid profile, including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), lipoprotein a (Lp(a)) and fasting blood sugar (FBS) concentrations. Systolic and diastolic blood pressures (SBP and DBP) were also measured. Results The mean ages of firefighters and administrative staff were 42.45 ± 6.75 and 44.64 ± 5.83 y, respectively. The prevalence of overweight and obesity was 45% and 24% in firefighters and 54% and 23% in administrative staff, respectively. High waist-to-hip and waist-to-stature ratios were detected in 26.4% and 81.3% of firefighters versus 33.3% and 89.7% of the control group, respectively. No significant differences were observed between the mean of TC, TG, HDL-C, LDL-C and FBS concentrations. The mean of Lp(a) was significantly higher among firefighters ( P<0.05). About half of the subjects in both groups had TC >5.17, TG >1.69, HDL-C <1.03 nmol/L and Lp(a) >25 mg/dL. There were no significant differences between the SBP and DBP of subjects. There was no significant difference in smoking habits between the two groups. Conclusions Considering the high prevalence of overweight and obesity, high TC, TG and Lp(a) and low HDL-C concentrations among all firefighters, it seems necessary to provide fitness-promotion and nutritional education programs for the prevention of obesity-related chronic diseases such as CVD.

BACKGROUND: Diabetes mellitus is a common disease worldwide which affects renal function. Cardiovascular morbidity and mortality in diabetes patients can be accelerated by dyslipidemia. Small dense lowdensity lipoprotein-cholesterol (sdLDL-C) is atherogenic and its predominance has been known as a cardiovascular risk factor. The study aimed to assess the validity of calculated sdLDL-C using three different formulae and its association with other clinical variables in diabetic patients with and without nephropathy, and also to determine the best suited formula to measure sdLDL-C.METHODS: The study subjects were divided into two groups based on the amount of albumin excreted in the urine. Group I or the control group consisted of diabetic subjects without microalbuminuria, while group II consisted of diabetic subjects with microalbuminuria. Blood glucose, glycated haemoglobin (HbA1c), creatinine, total cholesterol (TC), triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), LDL-C and apoB were estimated. Three formulae used for the validation of calculated sdLDL-C were TG/HDL, sdLDL (mg/dL) = 0.580 (nonHDL) + 0.407 (direct-LDL-C) – 0.719 (calculated-LDL-C) – 12.05, and LDL-C/LDL apoB.RESULTS: There was no significant difference in sdLDL-C levels of diabetic subjects with and without nephropathy. The sdLDL-C had strong correlation with TC, TG, LDL-C, very-low-density lipoprotein (VLDL), non-HDL and apoB in both study groups. ROC curve showed that LDL-C/LDL apoB derived sdLDL-C had better sensitivity (85%) and specificity (69%) compared to other two measures.CONCLUSION: Though the calculated sdLDL-C do not predict the occurrence of nephropathy in diabetes subjects, it may still be used in conjunction with the traditional markers since it is cost effective. The LDL-C/LDL apoB formula is the best predictor of sdLDL-C among the three equations.KEYWORDS: HDL-C, LDL-C, Microalbuminuria, sdLDL-C, T2DM

Introduction: Family Planning is a national strategy of Indonesia government to manage the population growth. Depo Medroxyprogesterone Acetate (DMPA) is one of injectable contraceptives most widely used because it is simple and easy to obtain. However, it has various side effects causing imbalance of hormone estrogen, in turns to result in a decrease in HDL (High Density Lipoprotein) and an increase in LDL (Low Density Lipoprotein) which will result in an increase in total cholesterol. It will also affect changes in fat metabolism in human body due to hormonal influences. This results in dyslipidemia and atherosclerosis. Method: The method in this study is an experimental study with a pretest-posttest control group design. Results: The purpose of this study was to determine the relationship between duration of use of DMPA injections with lipid profile levels in mice. The data were analyzed by using the Paired t-test parametric test to compare between treatment groups. This study found that there were significant differences in HDL levels and total cholesterol levels between before and after administration of DMPA injections on the 14th and 35th days. There is a significant relationship between the duration of administration of DMPA injections with HDL levels and total cholesterol levels in mice. However, there was no difference in LDL levels and triglyceride levels between before and after administration of DMPA injection on day of 14 and day of 35, while, there was a significant difference between before and after the 35th day. There is no relationship between duration of administration of DMPA injections with LDL levels, while there is a relationship among mice triglycerides. Conclusions: Administration of DMPA injections for a long time lowers HDL.

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.
