Effect of Egyptian Date Palm Pollen (Phoenix dactylifera L.) and Its Hydroethanolic Extracts on Serum Glucose and Lipid Profiles in Induced Diabetic Rats

Diabetes is a major health global problem that has reached alarming levels. The present study aims for studying the effect of date palm pollen (Phoenix dactylifera L.) El-Hayani cultivar on serum glucose and lipids profile in induced diabetic male albino rats. Palm pollen chemically analyzed besides chemical constituents, mineral contents, polyphenols and flavonoids. Male Albino rats (36 rats weight 170-190 gm) were divided into 6 groups. 1: Normal control (-), 2: Alloxanized diabetes control (+) (150 mg/Kg rat body weight). Diabetic groups 3 and 4 had 0.5%, 1.0% date palm pollen, respectively, also diabetic groups 5 and 6 had 100 ppm, 200 ppm date palm pollen extract, respectively. At the end of the experiment (4 weeks) rats were fasted overnight and anesthetized and blood samples were taken for analysis of serum glucose, lipids profile and renal-hepatic function parameters, relative organ weight data obtained are statistically analysis. Results showed that the major polyphenolic components were that e-vanillic acid (16.33 mg/100 g), pyrogallol (15.02 mg/100 g), epicatechin (11.04 mg/100 g), catechin (10.96 mg/100 g). While, date palm pollen was rich in hesperidin (8.84 mg/100 g), Kaempferol 3,2 p-coumaroyl glucose (6.92 mg/100 g), hesperitin (5.10 mg/100 g), rutin (3.11mg/100 g) as flavonoids components. Date palm pollen has high content of protein, calcium and iron (30.87 g/100 g, 510.82 and 236.50 mg/100 g), respectively. Also, serum glucose decreased significantly in diabetic groups (3, 4, 5 and 6, respectively) (179.47, 137.80, 156.77, 145.47 mg/100 mL, respectively). Lipids profile, renal and liver functions were improved significantly (P < 0.05) in diabetic groups which had date palm pollen or its extracts. It is concluded that the dried date palm pollen 1% in the diet and 200 ppm extract are more effective compared with controlling diabetes mellitus, also improve renal and liver functions. Diabetics are advised to eat date palm pollen and are considered treatment foods for Diabetes Mellitus.

Sex Hormones Affect Aging Process by Influencing Lipid Profiles, Cellular Immunological Function and Lipid Peroxides and Oxidation System

Objectives To investigate the correlation between sex hormones(SH) and aging. Methods Through epidemiological investigation in our country, the levels of SH were measured by radioimmunoassy; lipid profile, glucose and apolipoprotein by automatic biochemic analytical instrument; T cell subsets by flow cytometer; and MDA, SOD were evaluated by the thiobarbituric acid (TBA) test and the nitrite method modified by Oyanagui respectively using spectrophotometry. Results In men, the serum levels of follicle stimulating hormone ( FSH)、luteinizing hormone(LH) increased significantly with aging, but serum prolactin(PRL) and progesterone(P) levels remained unchanged in all life; Both testosterone (T) and free testosterone (FT) all decreased greatly with aging, but 17β - estradiol( 17β - E_2) was reverse ; E_2 was negatively correlated with T and E_2/T increased with aging. The level of serum total cholesterol (TC) increased with aging, but triglycerides (TG) remain unchanged; compared with young group, high - density lipoprotein cholesterol ( HDL - C) ; HDL - C/TC of other groups decreased significantly, but low - density lipoprotein cholesterol ( LDL - C ) changed inversely; HDL- C/LDL- C reduced slightly with aging and showed no difference between groups. Apolipoprotein A1 (apoA1) and apoB all enhanced greatly with aging; meanwhile the ratio of apoA1/apoB decreased. The concentration of serum glucose (GLU) was unchanged in all life. To compare with those in the young group, CD3 + , CD4 + in other groups reduced greatly, CD4 + remained unchanged. Meanwhile, CD8 + increased significantly with aging. Compared with the young group, serum malondialdehyde(MDA) value of the old ones increased obviously, but the activity of superoxide dismutase(SOD) was reverse. By partial correlation analysis (controlling BMI, FSH, LH and PRL), TC、 LDL-C、apoA1、apoB、CD8 + 、MDA of men all presented a positive correlation with E_2/T respectively, their correlation coefficients (γ) were 0. 262、0. 136、 0. 532、0. 379、0. 394、0. 234 (P < 0. 001 ) ; HDL - C、 HDL- C/TC、HDL- C/LDL- C、CD3 + 、CD4 +/CD8 + 、SOD showed a negatively correlation with E_2/T respectively, γequaled - 0.563、- 0.332、- 0.654、- 0.1530、-0.4140、-0.236(P<0.001). In women, the serum concentrations of FSH、LH increased significantly after menopause; PRL increased little with aging; compared with young group, E_2 and P in postmenopausal groups reduced obviously, E_2/P revealed significant reduce with aging. T enhanced significantly after menopause, but nor did FT. E_2, P and the ratio of E_2/P were negatively correlated with age respectively by bivariate correlation analysis, and a positive relation between T and age. After 70 years old, the level of TC increased obviously, and so did that of TG after menopause; HDL decreased with aging, but LDL increased after 70, with the result that the ratios of HDL- C/TC and HDL- C/LDL- C all reduced with aging; apoA1 decreased gently after 70, but apoB increased signifi- cantly after menopause; correspondingly, the ratio of apoA1/apoB declined obviously. The concentration of GLU increased with aging. CD3 + and CD4 + didn't change until 60, but reduced after 60. Compared with the young groups, CD8 + remained unchanged, CD4 +/CD8 + reduced greatly with aging, CD4 + and CD8 + presented a negatively correlation with age respectively. The value of MDA in serum of women increased notably after 70 years old, but SOD activity already decreased significantly from 60. By partial correlation analysis (controlling BMI, FSH, LH and PRL), HDL-C、CD4 +、CD4 +/CD8 + showed a certain correlation with E_2/P respectively; γ were 0. 245、 0.157、0. 154 ( P <0.05 ) ; TG、 LDL、 apoB、 apoA1/ apoB、SOD presented a negatively correlation with E_2/P respectively, γ were 0. 452、 0. 236、 0.321、 0. 135、 0.156、0.154、0.426 ( P < 0.05 ). Conclusions The Disequilibrium of SH had correlations with lipid profile, cellular immunological function and lipid peroxides and oxidation system; these suggested SH took an important role in the process of aging.

Effects of high‑grain diet feeding on fatty acid profiles in milk,blood,muscle,and adipose tissue,and transcriptional expression of lipid‑related genes in muscle and adipose tissue of dairy cows

Background High-grain(HG)diets affect lipid metabolism in the liver and mammary tissue of dairy cows,but its effects on muscle and adipose tissue have not been wide evaluated.Thus,the aim of this study is to clarify this issue.Methods Twelve Holstein cows were randomly divided into two groups:conventional diet group(CON,n=6)and the HG diet group(n=6).On day 7 of week 4,rumen fluid was sampled to measure pH,milk was sampled to meas-ure components,and blood was sampled to measure biochemical parameters and fatty acid composition.After the experiment,cows were slaughtered to collect muscle and adipose tissue for fatty acid composition and transcriptome analysis.Results HG feeding decreased the ruminal pH,milk’s fat content and long-chain fatty acid proportion(P<0.05)and increased the proportion of short-and medium-chain fatty acids in the milk(P<0.05)as compared with CON diets.The concentrations of blood cholesterol,low-density lipoprotein,and polyunsaturated fatty acids in the HG cows were lower than those in CON cows(P<0.05).In muscle tissue,HG feeding tended to increase the triacylglycerol(TG)concentration(P<0.10).Transcriptome analysis revealed changes in the biosynthesis of the unsaturated fatty acids pathway,the regulation of lipolysis in the adipocytes pathway,and the PPAR signalling pathway.In adipose tissue,HG feeding increased the concentration of TG and decreased the concentration of C18:1 cis9(P<0.05).At the transcrip-tome level,the fatty acid biosynthesis pathway,linoleic acid metabolism pathway,and PPAR signalling pathway were activated.Conclusion HG feeding leads to subacute rumen acidosis and a decreased milk fat content.The fatty acid profiles in the milk and plasma of dairy cows were changed by HG feeding.In muscle and adipose tissue,HG feeding increased TG concentration and up-regulated the expression of genes related to adipogenesis,while down-regulated the expression of genes related to lipid transport.These results complement our knowledge of the fatty acid composi-tion of muscle and adipose tissue in dairy cows and expand our understanding of the mechanisms by which HG diets affect lipid metabolism in muscle and adipose tissue.

Effect of dates on blood glucose and lipid profile among patients with type 2 diabetes

Poor fruit and vegetable consumption is one of the 10 major risk factors for mortality.There is a misconception regarding the consumption of dates among patients with diabetes.This manuscript assessed the effects of date consumption on fasting and postprandial blood glucose,glycated hemoglobin,total cholesterol,triglycerides,low-density lipoproteins,high-density lipoproteins,and microbial markers.Four literature databases were searched for relevant articles.Of the 595 studies retrieved,24 assessed the effects of dates on glycemic control and lipids.Overall,the evidence suggests that dates have a lowering effect on blood glucose.Dates reduce total cholesterol and triglyceride levels and increase high-density lipoprotein levels.Dates also promote the abundance of beneficial gut microbiota.Therefore,patients with diabetes and dyslipidemia can consume dates to reduce their blood glucose,cholesterol,and triglycerides.

Assessment of post-myocardial infarction lipid levels and management:Results from a tertiary care hospital of Pakistan

BACKGROUND Lipid treatment practices and levels in post-acute myocardial infarction(AMI)patients,which are crucial for secondary prevention.AIM To evaluate the lipid treatment practices and lipid levels in post-myocardial infarction(MI)patients at a tertiary care hospital in Pakistan.METHODS In this cross-sectional study,we analyzed patients who had experienced their first AMI event in the past 3 years.We assessed fasting and non-fasting lipid profiles,reviewed statin therapy prescriptions,and examined patient compliance.The recommended dose was defined as rosuvastatin≥20 mg or atorvastatin≥40 mg,with target total cholesterol levels set at<160 mg/dL and target low-density lipoprotein cholesterol(LDL-C)at<55 mg/dL.RESULTS Among 195 patients,71.3%were male,and the mean age was 57.1±10.2 years.The median duration since AMI was 36(interquartile range:10-48)months and 60% were diagnosed with ST-segment elevation MI.Only 13.8% of patients were advised to undergo lipid profile testing after AMI,88.7% of patients were on the recommended statin therapy,and 91.8% of patients were compliant with statin therapy.Only 11.5% had LDL-C within the target range and 71.7% had total cholesterol within the target range.Hospital admission in the past 12 months was reported by 14.4%,and the readmission rate was significantly higher among non-compliant patients(37.5%vs 5.6%).Subsequent AMI event rate was also significantly higher among non-compliant patients(43.8%vs 11.7%).CONCLUSION Our study highlights that while most post-AMI patients received the recommended minimum statin therapy dose,the inadequate practice of lipid assessment may compromise therapy optimization and raise the risk of subsequent events.

Prevalence of Dyslipidemia among Patients Received at the Biochemistry Unit of the Charles de Gaulle Pediatric University Hospital in Ouagadougou

Introduction: Cardiovascular disease represents a major public health burden worldwide. Research and management of risk factors contribute to the prevention of these diseases. The aim of this study was to assess the prevalence of dyslipidemia in the biochemistry unit of the Charles De Gaulle Pediatric University Hospital (CHUP-CDG) in Ouagadougou. Material and Methods: This was a descriptive and analytical cross-sectional study, with retrospective data collection from January 1, 2020 to December 31, 2022. Patients of all ages who performed a lipid panel in the CHUP-CDG biochemistry unit during the study period have been included. Results: A total of 2872 patients have been included. The mean age of the study population was 27.72 ± 19.51 years and the M/F sex ratio was 0.81. Among the patients, 22.84% had at least one dyslipidemia. The prevalences of hypercholesterolemia, hypo-HDL cholesterolemia and hyper-LDL cholesterolemia were 11.57%, 49.19% and 57.50% respectively. Hypertriglyceridemia and mixed hyperlipidemia were present in 9.04% and 2.08% of patients. Hypercholesterolemia was significantly more frequent in the female sex (p = 0.0077);hyper-LDL cholesterolemia (p = 0.0255) and mixed hyperlipidemia (p Conclusion: The relatively high prevalence of dyslipidemia in the study indicates a worrying situation. It would therefore appear essential to extend the search for risk factors nationwide, particularly those that can be modified, in order to reduce morbidity and mortality linked to cardiovascular disease.

Smoking and Serum Lipid Profiles in Schizophrenia

Schizophrenia is associated with a high preva- lence of cigarette-smoking and abnormal lipid profiles. The purpose of this study was to determine whether the profiles differ between schizophrenic smokers and non-smokers and whether the lipid profiles are related to psychopathological symptoms. Serum lipid profiles were measured in 130 male inpatients with DSM-IV-defined schizophrenia： 104 smokers and 26 non-smokers. Symptoms were assessed using the Positive and Negative Syndrome Scale （PANSS）. Our results showed that positive PANSS symp- toms were fewer in smokers than in non-smokers, while the negative symptoms were fewer in those who smoked more cigarettes. Total protein and globulin levels were significantly lower in the smokers than in the non-smokers. However, there was no significant difference in total cholesterol, triglycerides, high-density lipoprotein choles terol （HDL-c）, low-density lipoprotein cholesterol, apolipoprotein A1, or apolipoprotein B between the smokers and non-smokers. However, the PANSS positive subscale had a significant negative correlation with the HDL-c levels （a protective factor） in the smokers but not in the non-smokers. Our findings suggest that schizophrenic patients who smoke have fewer psychotic symptoms, but contrary to expectation, smoking does not alter lipid profile levels.

Blood lipid profiles following nonfocused ultrasonic treatment for noninvasive body contouring

Aim:Blood lipid profiles changed following nonfocused ultrasound treatments for body contouring.The present study elucidates clinical effects of these devices on adipose tissue.Methods:Ultrasound treatments for 5 males and 5 females in a supine position,ages 37-67 years,were applied at 20 KHz and 3.0 W/cm2 in modulated emission.Whole abdomen was treated by an ultrasound handpiece for 30 min followed by a 6-min lymphatic drainage.Waist circumferences at the level of the umbilicus and body weight were measured before and immediately after treatment.Blood lipid profiles including total cholesterol,low-density lipoprotein,high-density lipoprotein,triglyceride(TG),nonesterified fatty acid(NEFA)and lipoprotein-a were measured at baseline,every 10 min during treatment,and 15,30,45,60,75,and 90 min after treatment completion.Results:NEFA showed statistically higher values after 10 min following treatment initiation.Subsequent values remained high despite some fluctuation,reaching a maximum at 90 min.In contrast,TG gradually decreased in concentration until the last measurement,especially for the first 30 min,with statistically significant reduction.Changes in other lipid profiles and lipoprotein-a were not significant.Conclusion:Changes in NEFA concentration were significant following ultrasound treatment,and suggest that metabolism of TGs stored within the adipocytes occurred immediately after treatment initiation.

Relationships among body weight,lipids and bone mass in elderly individuals with fractures:A case-control study

BACKGROUND The prevalence of osteoporosis and low bone mass is steadily rising each year.Low body weight is commonly linked to diminished bone mass and serves as a robust predictor of osteoporosis.Nonetheless,the connection between body mass index(BMI),bone mineral density,and lipid profiles among the elderly remains elusive.AIM To examine the association between BMI and bone mass,explore the correlation between lipid profiles and bone mass,and delve into the interplay between lipid metabolism and bone health.METHODS The study included 520 patients aged≥65 years(178 men and 342 women).Age,sex,weight,and height were recorded.Femoral neck bone mineral density and T scores were determined using a dual-energy X-ray absorptiometry scanner.Blood calcium(Ca),phosphorus(P),albumin(ALB),alkaline phosphatase(ALP),aspartate aminotransferase,alanine aminotransferase,triglyceride(TG),total cholesterol(TC),high-density lipoprotein(HDL)and low-density lipoprotein(LDL)levels were measured.Patients were classified by sex(male and female),age(65-79 years and≥80 years),and T score(normal bone mineral density,osteopenia and osteoporosis).RESULTS Age,sex,BMI,and ALP and TG levels were independent risk factors for osteoporosis.For the 65-79-and≥80-yearold groups,females presented lower T scores than males.Ca,P,ALB,ALP,TC,HDL and LDL levels were significantly different between men and women in the 65-79-year-old group.In addition,BMI and TG levels were significantly decreased in osteoporotic patients compared with patients with normal bone mass.TC levels declined in 65-to 79-year-old male and female osteoporosis patients.In the group of women aged≥80 years,osteoporotic patients showed significantly increased ALP levels.Furthermore,we found positive correlations between BMI and TG levels in the male and female patient groups.However,we found no significant differences in ALB,Ca,P,HDL and LDL levels in osteoporotic patients compared to patients with normal bone mass.CONCLUSION Osteoporotic patients showed significantly decreased BMI and TG levels compared with those with normal bone mass.BMI showed positive correlations with TG levels in male and female patients.These results indicate correlations between BMI and bone mass and between lipid profiles and bone mass.

Correlation between Serum CD36 Level and Lipid Profile in Patients with Type 2 Diabetes Mellitus, Khartoum State, Sudan

Background: Diabetes mellitus (DM) is a chronic metabolic disorder characterized by hyperglycemia. DM-related dyslipidemia are associated with complications resulting from progressive damage of various organs. CD36 is 88-kD, class B scavenger receptor, expressed on different types of cells. In diabetic patients, LDL particles are glycated with strong level;this increases CD36 expression, initiates foam cell formation and accelerates atherosclerosis. Objective: This study aimed to determine the correlation between serum CD36 level and lipid profile among patients with type 2 diabetes mellitus in Zeenam Specialized center, Khartoum State, Sudan, in a period between 2019 and 2022. Methodology: Hundred participants at different ages were included in this study;70 were type 2 diabetic patients (cases) and 30 apparently healthy individual (control). 3 ml of venous blood were collected from the participants by using a sterile needle and syringe into a labeled plain container. Each sample was stood until complete clot occurs. Clotted blood sample was then centrifuged to obtain the serum. Then they were used for measurement of total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride and soluble CD36 levels. Total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were measured using Biosystem chemistry analyzer BTS-302. Serum CD36 was measured using Microplate Reader (URIT-660). Results: The results revealed that serum total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels were significantly higher in patients with type 2 diabetes mellitus compared with control (P = 0.03, P = 0.031, P = 0.000, P = 0.000) respectively, while there is no statistically significant differences in serum CD36 level between cases and control (P = 0.129). Also this study showed that there is no statistically significant correlation between serum CD36 level and total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, age and body mass index. Conclusion: This study concluded that there is no statistically significant difference in serum CD36 level between cases and control. And sCD36 level was not correlated with total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, body mass index, and age.

Effect of resistance training volume on body adiposity,metabolic risk,and inflammation in postmenopausal and older females:Systematic review and meta-analysis of randomized controlled trials

Purpose:This meta-analytical study aimed to explore the effects of resistance training(RT) volume on body adiposity,metabolic risk,and inflammation in postmenopausal and older females.Methods:A systematic search was performed for randomized controlled trials in PubMed,Scopus,Web of Science,and SciELO.Randomized controlled trials with postmenopausal and older females that compared RT effects on body adiposity,metabolic risk,and inflammation with a control group(CG) were included.Independent reviewers selected the studies,extracted the data,and performed the risk of bias and certainty of the evidence(Grading of Recommendations,Assessment,Development,and Evaluation(GRADE)) evaluations.Total body and abdominal adiposity,blood lipids,glucose,and C-reactive protein were included for meta-analysis.A random-effects model,standardized mean difference(Hedges’ g),and 95% confidence interval(95%CI) were used for meta-analysis.Results:Twenty randomized controlled trials(overall risk of bias:some concerns;GRADE:low to very low) with overweight/obese postmenopausal and older females were included.RT groups were divided into low-volume RT(LVRT,~44 sets/week) and high-volume RT(HVRT,~77 sets/week).Both RT groups presented improved body adiposity,metabolic risk,and inflammation when compared to CG.However,HVRT demonstrated higher effect sizes than LVRT for glucose(HVRT=-1.19;95%CI:-1.63 to-0.74;LVRT=-0.78;95%CI:-1.15 to-0.41) and C-reactive protein(HVRT=-1.00;95%CI:-1.32 to-0.67;LVRT=-0.34;95%CI,-0.63 to-0.04)) when compared to CG.Conclusion:Compared to CG,HVRT protocols elicit greater improvements in metabolic risk and inflammation outcomes than LVRT in overweight/obese postmenopausal and older females.

Body mass index and serum lipid profile influence serum prostate-specific antigen in Chinese men younger than 50 years of age

This study is to assess the potential factors that could affect the serum prostate-specific antigen （PSA） level in healthy younger men. We evaluated the associations of age, body mass index （BMI） and serum lipid profile with serum PSA level in 6774 Chinese men （aged 20-49 years） who received a routine health examination. Eligible men were classified into 10-year age groups, BMI was categorized as underweight （〈18.5）, normal （18.5-22.9）, overweight （23.0-24.9）, obese （25.0-29,9） and very obese （〉30） according to the redefined World Health Organization （WHO） criteria for the Asia-Pacific region. PSA levels were compared among groups as well, In multiple linear regression analysis, PSA was positively correlated with age （P〈0.0001）. Negative correlations existed between PSA and BMI （P〈0.0001） and triglyceride level （P=0.01）. No relationship could be found between PSA and serum cholesterol （P=0.711） or high-density lipoprotein （HDL; P =0.665）. In addition, we found that serum PSA levels increased with age and decreased with BMI. Our study demonstrates that age, BMI and triglyceride levels influence the PSA level in men 〈50 years of age.

High Physical Activity is Associated with an Improved Lipid Profile and Resting Heart Rate among Healthy Middle-aged Chinese People

Objective To investigate the effects of physical activity （PA） on dyslipidemia and elevated resting heart rate （RHR） in a large-scale cross-sectional study in China. Methods We recruited community-based individuals who were 40-60 years old using a cluster sampling method. The PA levels of the participants were classified as low, moderate, or high, using the International Physical Activity Questionnaire. Dyslipidemia was defined as the detection of abnormalities in lipid indicators, and 4 lipid parameters were evaluated using fasting blood samples. Multivariate logistic regression analyses were used to evaluate the associations of PA with dyslipidemia and RHR. Results A total of 10,321 participants （38.88% men） were included in this study. The percentages of individuals with high, moderate, and low PA levels were 46.5%, 43.9%, and 9.6%, respectively. In both men and women, high PA provided odds ratios of 0.88 [95% confidence interval （CI）： 0.83, 0.94] for dyslipidemia and 0.82 （95% CI： 0.73, 0.92） for elevated RHR, compared to participants with low PA. Conclusion Our data suggested that substantial health benefits （related to dyslipidemia and elevated RHR） occurred at higher intensity PA, with greater energy consumption, in middle-aged Chinese people, and particularly in men.

Helianthus tuberosus(Jerusalem artichoke) tubers improve glucose tolerance and hepatic lipid profile in rats fed a high-fat diet

Objective:To analyze the effects of feeding Helianthus tuberosus(HT) tubers on glucose tolerance and lipid profile in rats fed a high-fat diet(HFD). Methods:A normal HFD or HFD including 10 w/w% HT tubers(HFD + HT) was fed to F334/Jcl rats. After 10 weeks,organ weights,glucose tolerance,and lipid profile were analyzed. Results:The body weight,liver weight,and epidermal fat content in the HFD group were higher than those of the normal group,and similar to those of the HFD + HT group. The oral glucose tolerance test at 10 weeks revealed that the blood glucose level 30 minutes after beginning the test in the HFD + HT group was significantly lower than that in the HFD group. Liver triglyceride and total cholesterol levels in the HFD + HT group were significantly lower than those in the HFD group. Fecal triglyceride and total cholesterol levels in the HFD + HT group were higher than those in the HFD group. Histological analyses revealed that fat and glycogen accumulation increased in the HFD group,but decreased in the HFD + HT group. Conclusions:These results indicate that HT tubers have anti-fatty liver effects based on improvements in glucose tolerance and the hepatic lipid profile.

The Effect of Different Levels of Sesame Oil on Productive Performance, Egg Yolk and Blood Serum Lipid Profile in Laying Hens

Addition of sesame oil into layer diets has been proved to enrich the proportion of polyunsatu-rated fatty acids in animal’s products. In this study, the effects of different levels of sesame oil in the diets on the performance, egg yolk and blood serum lipid profile of Isa Brown laying hens were investigated. A total of 96 layers were assigned into 4 groups to receive either 1 of 4 different diets contained 0.0%, 1.5%, 3.0% and 4.5% sesame oil, respectively. Sample of 12 eggs obtained from each groups were assessed for egg quality. The egg yolk fatty acid profile was determined with gas chromatography. Results revealed that the higher levels of sesame oil in the diet decreased egg production, egg weight, and egg yolk color except feed conversion ratio. In addition, supplementation of sesame oil increased the flow index of the eggs and the Haugh unite. The egg yolk lipid profile was not significantly different in the sesame oil fed groups, whereas, compare to control, it decreased the level of cholesterol. The blood serum lipid profile decreased in the sesame oil groups compare to control group. Meanwhile, monoacildigliserol also decreased in the sesame addition groups. In parallel with increasing levels of sesame oil, monounsaturated fatty acid (oleic acid) in the egg yolks significantly increased compared to the control (37.00%, 42.89%, 42.20% and 43.48%, respectively). It can be implied that sesame oil supplementation into the laying hens diet is necessary to produce monounsaturated fatty acid (MUFA) enriched eggs.

Effects of Olive Oil and Grape Seed Oil on Lipid Profile and Blood Pressure in Patients with Hyperlipidemia: A Randomized Clinical Trial

Background and Aims: Hyperlipidemia is one of clear risk factors of diabetes. Regarding its importance, this study was designed to compare the effects of olive oil and grape seed oil on serum lipids and blood pressure in patients with hyperlipidemia in 2015. Methods and Results: In this clinical trial, 60 patients with hyperlipidemia who met inclusion criteria were recruited. Subjects were randomly assigned 3 groups: 1) consume 20 ml/day refined olive oil;2) consume 20 ml/day grape seed oil;3) the control group received no oil. The study period was six weeks. All participants were under Step I diet. Height and weight measurements were taken by Seca scale. Blood pressure, total cholesterol, high-density lipoprotein, triglyceride and fasting blood sugar were measured at baseline and after 6 weeks by standard methods. Low-density lipoprotein levels were calculated by the Friedewald’s formula. Data were analyzed with ANOVA test in SPSS software version 16.0. Sixty participants (36 female and 24 male) with the average age of 47.5 ± 9 y and the mean body mass index of 31.78 ± 5.41 kg/m2 had completed the study. Olive oil intervention decreased systolic blood pressure significantly compared to grape seed oil group (P = 0.01). Triglyceride was significantly decreased in olive oil and also triglyceride groups (P = 0.02 and 0.004, respectively). Conclusion: Overall, the effects of olive oil and grape seed oil were better than control group. However, we suggest the substitution of dietary lipids with olive oil because of its more beneficial effects.

Lipid Profile of Coronary Heart Disease Patients: A Prospective Observational Study

Background: Coronary heart disease (CHD) remains the major cause of mortality and morbidity in the entire world population despite therapeutic advances that control many risk factors. Lipid profile is regarded as an important factor in the development of coronary heart disease. There have been numerous studies confirming the association of hyperlipidemias with coronary heart disease in most of the Western as well as Asian countries of the world. But we have very little data on the relation between CHD and lipid profile. Aim of the Study: The aim of this study was to assess abnormal lipid levels and their association with coronary heart disease. Methods: This comparative observational study was conducted at the Department of Cardiology in M. Abdur Rahim Medical College, Dinajpur, Bangladesh from January 2019 to December 2019. Properly written consent was taken from all the participants before starting the main part of the investigation. Obeying inclusion and exclusion criteria of the study, a total of 131 participants were finalized as the study population. Among them, the Case Group was formed with 90 patients who had CHD, and with 41 healthy people, the Control Group was formed. All necessary data were collected, analyzed, and disseminated by several programs of MS-Office and SPSS version 23. Result: The study was conducted with 90 case group participants and 41 control group participants. Among the case group, 78% were male and 22% were female. Among the male case group participants, 44.29% were from 51 - 60 years of age, 35.71% were from 41 - 50 years of age and the rest 20% were above 60 years of age. On the other hand, among the female participants of Case Group, 45% were from 51 - 60 years of age, 30% from 41 - 50 years of age, and 25% were over 60 years of age. Regression analysis between the male and the female showed the P-value of 0.242. Serum cholesterol concentration and HDL concentration were significant between the Case and Control groups in all age groups and the P-value was <0.0001 in every age group. Triglyceride concentration was significant between the Case and Control groups in 41 - 50 and 51 - 60 years age groups with a P-value of <0.0001. But in the >60 years age group, we did not find any significant correlation and there the P-value was 0.478. LDL concentration between the groups showed significant correlations between the Case and Control groups in 41 - 50 and 51 - 60-years’ age groups where the P values were found, <0.0001 and 0.0002 respectively. But in the >60 years’ age group, we did not find any significant correlation and there the P- value was 0.515. Conclusion: In this study, it was found that the total cholesterol, triglycerides, HDL cholesterol, and LDL cholesterol concentrations were significantly higher in coronary heart disease (CHD) patients.

Objectives: To determine the anthropometric indices, lipopolysaccharide-binding proteins (LBP), and lipid profile in patients with metabolic endotoxemia. Methods: The study comprised of 47 patients with metabolic endotoxemia (the metabolic endotoxemia group) and 43 controls (the control group). Patients in the metabolic endotoxemia group were categorized further into three subgroups including the normal weight group (n=8), the overweight group (n=12) and the obese group (n=27). Height, weight, waist, and hip circumference were measured, and waist-hip ratio (WHR) and body mass index (BMI) were calculated. LBP was determined by ELISA and total cholesterol, triglycerides, high density lipoprotein by the respective enzymatic colorimetric methods. In addition, low density lipoprotein and very low density lipoprotein were determined by Friedewald's formula. Results: The mean waist circumference (WC), hip circumference (HC), BMI, total cholesterol, low density lipoprotein, and LBP of the metabolic endotoxemia group were significantly higher (P<0.05) than those of the control group. WHR, TG, high density lipoprotein and very low density lipoprotein of the metabolic endotoxemia group were not significantly different (P>0.05) from those of the control group. The mean WC, HC, WHR, and BMI of the obese group with metabolic endotoxemia were significantly higher (P<0.05) than those of the overweight group and the normal weight group with metabolic endotoxemia. Significant positive correlations were obtained between BMI and LBP (r=0.610, P=0.001), total cholesterol and LBP (r=0.385, P=0.007), TG and LBP (r=0.356, P=0.014) in patients with metabolic endotoxemia. Conclusions: Metabolic endotoxemia arising from increased circulating level of bacterial derive particles consequent to perturbation in the gut microbial community and the elevated ;serum level of LBP may precede the development of obesity, characterized by dyslipidemia, dysregulation of gut energy harvest, and metabolic energy imbalance.

Introduction to the International Symposium on Lipid Science and Health and research progress in lipid science and health

The International Symposium on Lipid Science and Health(ISLSH),which was organized annually by Oil Crops Research Institute of Chinese Academy of Agricultural Sciences(OCRI-CAAS)since 2016,has gained a strong reputation and attracted hundreds of delegates from around the world for discussion of lipid research trends and advances every year,to promote research and academic exchanges in the fields of lipid science and health.The 5th International Symposium on lipid Science and Health was successfully held in Wuhan,China,from October 23rd to 25th,2020,to celebrate the 60th anniversary of OCRI-CAAS.The two-day symposium gathered wellknown experts specialized in lipid science to share the current state of lipid research with emphasis on aspects covering:(1)lipid profiling and characterization,(2)lipid preparation and modification,(3)lipid improvement and regulation,and(4)lipid nutrition and health.The symposium was conducted by a combination of on-site and network meeting.More than 250 distinguished delegates from academia and industry participated in the on-site multidisciplinary meeting,and thousands of scholars attended the virtual event.This paper is as a record of the symposium proceedings and a brief summary of the advances and trends in 4 aspects of lipid science and health.

Evaluation of Lipid Profile in Obese and Non-Obese Hypertensive Adult Patients Attended in Medicine Department of a Medical College Hospital of Bangladesh

Background: By the dawn of this modern era of science, the prime challenge of physician is cardiovascular disease (CVD). The most important modifiable risk factors of CVDs are unhealthy diet, physical inactivity and tobacco use. The effects of unhealthy diet and physical inactivity include abnormal blood lipid, obesity and hypertension. We tried to evaluate and correlate the pattern of lipid profile in obese and non-obese hypertensive patients. Objectives: This study was conducted at medicine department of Cumilla Medical College Hospital. The principal aim was to evaluate the lipid profile in obese and non-obese adult hypertensive patients. Methodology: During this cross sectional analytical study, a total of 100 adult hypertensive patients were taken by purposive sampling. Among them 50 (group 1) patients were taken those were obese and 50 (group 2) patients taken those were non-obese according to BMI measurement on operational definition. Diagnosis of hypertension would be established with the help of ambulatory BP measurements two occasions few minutes apart. The staging of hypertension was done according to JNC7 Criteria. Morning blood samples were taken after 8 - 12 hours of fasting and lipid profiles were done on authentic laboratories. The laboratory values were interpreted according to the operational definition of dyslipidaemia. The ethical research and review committee approved the study protocol and signed informed consent was obtained from the participants. The statistics was analyzed using the IBM SPSS software of version 19.0. Statistical significance was set at p < 0.05. Results: Among the two groups, there were 56 (56%) males and 44 (44%) females. The mean age of group 1 (46.10 ± 11.09) was compared to that of group 2 (45.5 ± 10.6). Lipid profile abnormalities were significantly higher in the stage 2 hypertension (59.62%) and stage 3 hypertension (66.66%), higher in class 2 obese (100%) and class 3 obese subjects (100%), female hypertensive patients had significantly higher BMI than their male counterparts (27.24 ± 3.63 kg/m2 versus 29.29 ± 3.99 kg/m2), lipid profiles were higher in the female than male hypertensive patients (63.33% vs 55.35%) but only TC was statistically significant (4.45 ± 1.19 mmol/l versus 4.86 ± 1.29 mmol/l, p < 0.05). Those who were obese had significant high TG (p < 0.001), high TC (p < 0.001) and high LDL-C (p < 0.001). 38 (76%) of the obese hypertensive patients had dyslipidaemia whereas 21 (42%) of non-obese hypertensive patients had dyslipidaemia. In multivariate regression, TG was significantly and directly associated with BMI of subjects. Dyslipidaemia was more prevalent in the age group 30 - 59 of adult hypertensive patients. It showed that obese hypertensive patients had significantly higher SBP (p < 0.001), DBP (p < 0.001) than non-obese subjects. The mean TC (4.83 ± 0.95 mmol/l versus 4.15 ± 0.57 mmol/l, t = -9.70, p < 0.001), TG (2.64 ± 0.67 mmol/l versus 2.10 ± 0.45 mmol/l, t = -5.37, p < 0.001) and LDL-C (3.00 ± 0.82 mmol/l versus 2.44 ± 0.53 mmol/l, t = -9.11, p < 0.001) were also significantly higher among the hypertensive obese subjects. The mean HDL-C was however comparable in the two groups (1.25 ± 0.27 mmol/l versus 1.24 ± 0.57 mmol/l, t = -0.25, p = 0.08)...
