Abstract Background: Hyperlipidemia is a major risk factor for cardiovascular diseases. Cucumeropsis mannii and Citrullus lanatus commonly called pumpkin seeds or egussi, the oil-rich seeds, have already demonstrated hypolipidemic activity. In Africa, these seeds are popularly used in the preparation of local foods. During that thermal process, the fatty acid content of pumpkin seeds’ oils may be altered in their functionality. Thus, this work aims at studying the effect of stifled cooking on the quality and the lipid-lowering potential of oils’ extracts from Citrullus lanatus (CL) and Cucumeropsis mannii (CM). Methods: The oils were extracted from the pumpkin seeds (raw and cooked) by a mixture of chloroform and methanol (2/1). The acid, iodine, peroxide and thiobarbituric acid value of the oils were assessed. For 28 days, the oils were subsequently administered by oral intubation to high-fat diet induced hyperlipidemic rats. At the end of the experimentation, the lipid profile, the markers of the hepatic and kidney function were determined. Results: The oils extracted from raw CL and CM significantly reduced (p˂0,05) serum triglyceride, total cholesterol, Low Density Lipoprotein (LDL) cholesterol, uric acid, serum transaminases, creatinine, urea and increases the serum High Density Lipoprotein (HDL)cholesterol level relative to the oils extracted from cooked CM and CL. Moreover, the oil from cooked CL significantly (p<0.05) reduced some lipid profile and toxicity parameters (triglycerides and Alanine animotransferase) while increasing the serum HDL compared to the oil extracted from cooked CM. On the other hand, all the quality parameters of the raw materials followed the limits for vegetable oils, as opposed to cooked samples. Conclusion: Stifled cooking affects the lipid-lowering potential of CM oil compared to that of CL oil. Keywords: Citrullus lanatus; Cucumeropsis mannii; Cucurbitaceae, Hyperlipidemia, Stifled cooking.

Abstract Context Calculated non–high-density lipoprotein (HDL) cholesterol (non-HDLC) should selectively include cholesterol from atherogenic lipoproteins to be a reliable risk marker of cardiovascular disease. In hypertriglyceridemia (HTG), there is increased abundance of larger and less atherogenic triglyceride-rich lipoproteins (TRL), namely, larger very-low-density lipoproteins (VLDL), and chylomicrons. Objective We aim to demonstrate that serum triglyceride (TG) level has a substantial impact on non-HDLC’s ability to represent cholesterol from atherogenic lipoproteins, even though TG is not part of the calculation for non-HDLC. Design Analysis of lipid profile data Settings Lipid Clinic patient cohort, and Biochemistry Laboratory patient cohort Patients or Other Participants 7,492 patients in the Lipid Clinic cohort with baseline lipid profiles documented prior to starting lipid-lowering medications and 156,311 lipid profiles from The Ottawa Hospital Biochemistry Laboratory cohort. Intervention None Main Outcome Measure Our modeling process includes derivation of TG-interval–specific lipoprotein composition factor (LCF) for TRL, which represents the mass ratio of cholesterol to TG in TRL. A high LCF indicates that the TRLs are mainly the cholesterol-rich atherogenic remnant lipoproteins. A low LCF indicates that the TRLs are mainly the TG-rich larger VLDL and chylomicrons. Results As serum TG increases, there is progressive decline in the LCF for TRL, which indicates that the calculated non-HDLC level reflects progressive inclusion of cholesterol from larger TRL. This is shown in both cohorts. Conclusions Calculated non-HDLC is influenced by TG level. As TG increases, non-HDLC gradually includes more cholesterol from larger TRL, which are less atherogenic than LDL and remnant lipoproteins.

Objectives: The present study was conducted aiming to investigate lipid profile in patients with subclinical hypothyroidism as compared to age and sex matched controls.Methods: The study population consisted of total 80 subjects; 40 patients (cases) and 40 controls. Serum free tri-iodothyronine (fT3) and free thyroxine (fT4) were estimated by microplate competitive enzyme immunoassay, and thyroid stimulating hormone (TSH) measured by sandwich enzyme immunoassay. Lipid profile tests: Total Cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol were estimated by enzymatic methods and low density lipoprotein cholesterol (LDL) was calculated by Friedewald’s formula.Results: Significant differences were observed between lipid parameters in case Vs controls: total cholesterol (4.9±1.1 Vs 4.3±1.0 mmol/L, P=0.03), triglycerides (1.9±0.7 Vs 1.6±0.6 mmol/L, P=0.02) and LDL cholesterol levels (3.5±1.1 Vs 2.9±0.9 mmol/L, P=0.02). In case Vs controls no significant differences were observed between HDL Cholesterol (1.1±0.2 Vs 1.1±0.7 mmol/L, P=0.07), VLDL (0.9±0.4 Vs 0.8±0.3 mmol/L, P=0.1) and Cholesterol/HDL ratio (4.48±1.40 Vs 4.06±0.89, P=0.118). Elevated TSH level were found in cases Vs controls (12.42±7.08 Vs 2.69±0.20 mIU/L, P=0.01) which was statistically significant. The subjects on control group were euthyroid, however increased fT3 (3.9±0.8Vs 4.6±0.8 pmol/L, P=<0.01) and fT4 (17.1±3.9Vs 21.2±.3.7 pmol/L, P=<0.01) values were observed in controls than cases, which was statistically significant.Conclusion: The results of the present study suggest that cases of subclinical hypothyroidism are at risk of dyslipidemia as compared to controls. Large population based studies are needed to generalize these findings and establish the therapeutic guidelines for implementing lipid lowering agents in subclinical hypothyroidism.Asian Journal of Medical Science, Volume-5(3) 2014: 22-25http://dx.doi.org/10.3126/ajms.v5i3.9251

ABSTRACT Introduction Obesity is emerging as an epidemic worldwide. Obesity is associated with a number of comorbid conditions, such as diabetes mellitus, hypertension, cancer, dyslipidemia, cardiovascular abnormalities, anemia, obstructive sleep apnea, and psychosocial abnormalities. Aim This study aims at comparing the lipid profile levels of obese and nonobese men. Materials and methods This was a case—control study conducted at a tertiary care center. Totally, 80 men in the age group of 20 to 47 years attending the master health checkup were included in the study, out of which 40 men with normal body mass index (BMI) of 18 to 25 belonged to group I and 40 men with increased BMI of 30 and above belonged to group II. Lipid profile parameters, such as triglycerides (TGLs), total cholesterol, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol were estimated in them. The data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) software version 15.0. Results Statistically significant difference was found in the total cholesterol levels with a p-value of 0.040 while the difference in LDL cholesterol was statistically highly significant with a p-value of 0.040. Conclusion Among lipid profile parameters, only total cholesterol and LDL cholesterol showed significant difference between the obese and nonobese individuals. However, the other parameters like HDL cholesterol and TGLs did not show any significant difference. How to cite this article Babu SV, Jagadeesan AR, Ramalingam J.

Dyslipidemia is a metabolic disorder that is characterized with an elevation in the cholesterol serum levels that can be treated with various hypolipidemic drugs like rosuvastatin. The present study was undertaken to determine and evaluate the hypolipidemic effect of milk thistle seeds extract in comparison with rosuvastatin and the combination of both for the treatment of dyslipidemia in rats. Also its effect on blood glucose levels on experimentally induced dyslipidemic rats. In vivo studies were conducted on wister albino laboratory rats, in which 49 rats were induced to be dyslipidemic by a daily intragastric administration of cholesterol (2 g/kg). The induction of dyslipidemia was evaluated by comparing these rats with a negative control group that was composed of 10 healthy rats. Then, after one month dyslipidemia was induced in 49 rats that were divided into 6 groups, as the following; positive control group (n=9) received cholesterol (2 g/kg) for another one month, and the other five groups each of 8 rats continued to receive cholesterol (2 g/kg) for one month along with therapy as; rosuvastatin low dose (RL) group received 10 mg/kg, rosuvastatin high dose (RH) group received 20 mg/kg, milk thistle (MT) group received 7.15 mg/kg, (RL+MT) group received a combination of 10 mg/kg of rosuvastatin and 7.15 mg/kg of milk thistle, and (RH+MT) group received a combination of 20 mg/kg of rosuvastatin and 7.15 mg/kg of milk thistle. The statistical results of biochemical analysis showed that all the studied therapeutic protocols whether given alone; RL, RH, and MT or in a combination; RL+MT and RH+MT led to a significant (p≤0.05) hypolipidemic effect that reduced the total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) and increased the high density lipoprotein (HDL) cholesterol levels. In conclusion, all therapeutic protocols were effective in treating dyslipidemia, as they all reduced the TC, TG, LDL, and VLDL, and increased the HDL cholesterol significantly (p≤0.05). Furthermore, we found that milk thistle can be used in the management of dyslipidemia, as it has a hypolipidemic effect. Also, the addition of milk thistle to rosuvastatin therapy reduced the risk of developing diabetes mellitus (DM), as it has a glucose modulating activity either when it was given alone or in combination with rosuvastatin. Moreover, the combination of milk thistle and rosuvastatin was of a great benefit, as it gave an intensive goal of therapy than each one alone in altering all lipid profile parameters.

Abstract Objectives Red raspberries (RRB) contain a unique polyphenol profile associated with cardio-metabolic benefits. Fructo-oligosaccharides (FOS), as prebiotics, present an approach to augment the cardio-metabolic benefits of RRB through their known effects in modifying the gut microbiota composition. The objective of this study is to determine the effect of RRB intake with or without FOS on glucose and insulin responses and fasting lipid profile in insulin-resistant (IR) (n = 20) and metabolically healthy reference (R) adults (n = 11) in a single-blinded, randomized, 12-week crossover clinical trial. Methods In this crossover study, after one-week run-in, subjects consumed RRB (1 cup RRB equivalence) or RRB + FOS (1 cup RRB equivalence with 8 g FOS) for 4 weeks in random order separated by 4-week washout between supplementation periods. Before and after each supplementation period, glucose and insulin responses were assessed by 2-h postprandial glycemic challenge with RRB (75 g glucose equivalence) and the plasma lipid profile characterized (total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL) and triglycerides (TG)). Results IR group had significantly elevated fasting and postprandial glucose and insulin, and higher fasting TG and lower HDL compared to R at baseline (0-week) (P ≤ 0.05); no differences in TC and LDL between groups (P > 0.05). After 4-week intervention, RRB decreased TC and LDL of IR group from baseline by 7% (P = 0.024) and 9% (P = 0.007), respectively, whereas adding FOS significantly attenuated the lipid-lowering effect of RRB. Alternatively, addingFOS to RRB augmented RRB effect on glycemic variables: 4-week intake of RRB + FOS significantly decreased 30 min incremental areas under curve (iAUC 0–30) of IR group for glucose and insulin from baseline by 20% (P = 0.014) and 18% (P = 0.012), respectively. Conclusions 4-week RRB intervention improves glycemic and lipid profiles in people with IR. Adding FOS to RRB supplement enhanced the glycemic benefits, but attenuated the lipid-lowering effect of RRB. Funding Sources This work was supported by the National Processed Raspberry Council.

1. Changes in serum triglyceride and high density lipoprotein (HDL) cholesterol after a fatty meal have been studied in smokers and non-smokers. 2. Average serum triglyceride during the study was higher in smokers than in non-smokers. 3. In non-smokers there was a rise in the HDL2/HDL3 cholesterol ratio after oral fat, but not in smokers. 4. These findings are compatible with the hypothesis that smoking interferes with the lipolysis of triglyceride rich lipoproteins and the conversion of HDL3 into HDL2.

Back ground: In type 2 diabetes mellitus lipid abnormalities are almost the rule. Dyslipidemia has been noted to play an integral role in the pathogenesis and progression of micro and macrovascular complications in diabetes mellitus patients. The complications exemplified by renal, cerebrovascular and cardiovascular disease cause the most morbidity and mortality in this group of patients.Aims and Objectives: This study is aimed at understanding the pattern of dyslipidemia among type 2 diabetic patients. Materials and Methods: During two month study period, total 100 patients with diabetes mellitus were evaluated for dyslipidemia. Plasma glucose was estimated by GOD –POD method and Lipid profile by photometry method. Lipid profile was evaluated by investigating the subjects for total cholesterol, serum triglyceride, high density lipoprotein, low density lipoprotein and very low density lipoprotein. In statistical analysis data were analyzed by using various statistical methods like percentage, proportions and tables by using epi info software.Results: Out of 100 patients 72(72%) were males and 28(28%) were females. The mean  fasting blood sugar of total patients with type 2 diabetes mellitus was 158.35mg/dl. in male diabetics, fasting blood sugar level with diabetes mellitus was 157.56mg/dl and in female diabetics it was 159.14mg/dl. The pattern of dyslipidemia in our study showed significantly higher levels of serum cholesterol, serum triglyceride, LDL-C in both male and female diabetics and lower levels of HDL-C in female diabetics. There was no significant difference in lipid profile pattern in male and female diabetic patients except lower levels of HDL-C in female diabetic patients. Conclusion: This study showed that dyslipidemia is highly prevalent among type 2 diabetic patients.

Abstract Background The study was done to assess high-density lipoprotein (HDL) functionality and to correlate this with paraoxonase 1 (PON1) activity in malnourished children. It aimed to find the effect of malnutrition on changes in PON1 activity, HDL functionality, lipid profile and lipid hydroperoxide formation. Methods This case control study included 30 malnourished children (up to age 5 years) and 30 healthy controls in the paediatric inpatient department of SRTR Government Medical College Ambajogai, India. Clinically diagnosed cases depending on anthropometric indices were selected. Serum PON1 activity by using phenyl acetate as a substrate, HDL functionality by haemin by its protection on H2O2 and haemin induced LDL oxidation, lipid profile by routine enzymatic methods and lipid hydroperoxide using the FOX2 assay were measured. Results Malnourished children had significantly decreased PON1 activity (106.6 ± 12.74** vs. 132.23 ± 28.49 IU/L), HDL functionality (116.55 ± 8** vs. 132.29 ± 10.9%), total cholesterol (TC) (102.5 ± 16** vs. 116.4 ± 12.65 mg/dL), HDL-cholesterol (C) (33.41 ± 9.74** vs. 40.55 ± 5.85 mg/dL) and reduced total protein level (5.56 ± 0.91* vs. 6.06 ± 1.055) higher triglycerides (TG) (146.76 ± 34.97* vs. 125.96 ± 17.21 mg/dL) level and total hydroperoxide (TPX) levels (5.568 ± 1.70** vs. 3.22 ± 1.52 μM/L). *p < 0.05 **p < 0.001. PON1 activity (r2 = 0.576) and TC (r2 = 0.567) shows significant positive correlation with HDL functionality. PON1 activity, HDL-C, HDL functionality and TPX shows independent contribution towards malnutrition in children in multivariate and univariate logistic regression. TC lost its significance in multivariate regression. Conclusions Malnutrition leads to decrease in HDL functionality and increase in hydroperoxide levels with a decrease in PON1 activity.
