    Full Text Available Background: Taurine is an abundant amino acid in human cells, promoting ocular and biliary health, which is also used to treat congestive heart failure, hypertension, and hepatitis. Recently, taurine-enriched energy drinks have become popular with young adults, but the effects of taurine on serum lipids in young adults are unknown. Objective: We studied the influence of oral administration of taurine on serum lipid levels in healthy young women. Methods: Ten healthy young women with a mean body mass index of 20.0kg/m2, apolipoprotein E (apoE phenotype 3/3 and normal menstrual cycles participated. Each subject was instructed to orally ingest 1g of taurine powder after each meal (3g/day in addition to their usual diets during one menstrual cycle. Before and at the end of taurine intake, physical measurements and blood collection were performed in the morning after a 12-h fast, and 3-day weighted dietary records were obtained. Concentrations of serum lipids, apolipoproteins, and fatty acids in the serum phospholipid fraction were measured. Results: The subjects showed good compliance with taurine intake and none reported adverse effects during the experimental period. After taurine intake, concentrations of total cholesterol, low density lipoprotein cholesterol (LDL-C, free cholesterol, and apolipoprotein B (apoB increased (p<0.05, while phospholipids tended to increase (p=0.051. Fatty acids in the serum phospholipid fraction also significantly increased (p<0.05. However, triglyceride, remnant-like particle cholesterol, remnant-like particle triglyceride, apoE, the apolipoprotein A-1 (apoA- 1/apoB ratio and the LDL-C/apoB ratio were unchanged. Furthermore, body weight was significantly increased (p<0.01, but did not correlate with changes either in serum lipids or nutrient intakes. Conclusion: These results suggest that high taurine intake affects lipoprotein metabolism and increases serum lipids in slightly lean young women.

    Full Text Available Background. The toxicity of mercury which is used as mercury chloride in different parts of living world has been reported in literature. In our knowledge, however, these reports are on the effects of mercury on serum blood parameters. As lipids have important role in cell metabolism, we decided to study the effects of mercury on blood parameters which are related to lipid metabolism as well as its effect on hepatocyte triglycerides. Methods. Each group of 5 rats were treated with daily IP injections of either 10 mg/kg (Body Weight for 5 and 10 days or 5 mg/kg B.W. for 30 and 60 days, before determination of serum levels of triglycerides, cholesterol and lipoprotein fractions. Results. The results obtained are as follows. Daily intraperitoneal injection of 10 mg/kg B.W of mercury for 5 and 10 days elevated serum triglycerides by (10.9, 19.3 LDLc (16.5, 22.5 VLDLc (10.9, ,19.3 and hepatocytes containing triglycerides (105.1, 136.3 percent respectively. HDLc was decreased by (13.4, 17.3 percent. Daily intraperitoneal injection of 5 mg/kg body weight of mercury for 30 and 60 days elevated serum triglycerides by (34.7, 47.4. LDLc (28.9, 33.3, VLDLc (34.7, 47.4 and hepatocytes containing triglycerides (177.3, 213.4 percent respectively. HDLc was lowered by (22.9, 27.7 percent. Discussion. The results showed that mercury could affect lipid metabloism in a dose and time dependent manner. This effect might be considered as a possilbe cause of hyperlipidemia in those who are intoxified with this element.

    Hepatic fatty infiltration appears as an area of increased echogenicity. And many factors concerned to fatty infiltration. With 65 cases of fatty liver and 42 cases of normal group, we analyzed fatty liver with grading and attempt to find relations between grade of fatty liver and levels of body index, serum triglyceride, and serum lipid. And compared fatty liver with normal control group. Patients with fatty liver are higher percentage of supra-normal value in body index, serum lipid, and serum triglyceride than normal control group. As fatty infiltration progressed, serum lipid, serum trig-lyceride and body index are also increased. Conclusively ultrasonographic examination of liver with serum triglyceride, serum lipid, and body index are simple method, useful follow-up examination of fatty liver, and preventive routine check-up of chronic liver disease

    Full Text Available Fifty fresh and untreated patients of leprosy constituted the study group. Fifty, age and sex matched healthy individuals formed the controls. Ridly and Jopling system of classification was used in the study. Majority i.e 21 cases were of BT group, 12 of BB, 7 of BL, 9 of LL and one case was of TT leprosy. The serum triglyceride level was lower than normal in TT, showed no alteration in BT or BB and was insignificantly increased in bL and LL patients. The total cholesterol was lowerthan normal in TT, showed no alteration in BT or BB and was insignificantly increased in Bland LL patients. The total cholesterol was lower than normal in TT, whereas in BT, BB, BL and LL groups the levels were statistically decreased. The HDL cholesterol was within normal range in TT, significantly decreased in BT and LL patients, showed no significant alteration in BB and was insignificantly decreased in BL group. The LDL cholesterol in TT was low but was not so low statistically when compared with the controls, whereas in BT, BB, BL and LL groups the levels were statistically decreased. The VLDL cholesterol was within normal range in TT and BT, was raised insignificantly in 3 of 12 cases of BB, was within normal range in BL and in LL leprosy it was raised in one out of 9 cases. In the absence of any derangement of liver function tests, it can be concluded that leprosy per se leads to alterations in lipid metabolism. However, no correlation could be established between the group/type of leprosy, bacterial indices and levels of different lipid fractions in the present study.

    Full Text Available Aim: To examine the association of serum lipids, lipid ratios with Chronic Kidney Disease (CKD in a Chinese population. Methods: Data were drawn from a cross-sectional survey in China. CKD was defined as estimated glomerular filtration rate (eGFR < 60 mL/min/1.73m2 or albuminuria-to-creatinine ratio (ACR > 30 mg/g. Multivariable logistic regressions and multivariate regression models were used. Serum lipids and lipid ratios included total cholesterol (TC, triglyceride (TG, low-density lipoprotein cholesterol (LDL-C, high-density lipoprotein cholesterol (HDL-C, TG/HDL-C ratio, TC/HDL-C ratio and LDL-C/HDL-C ratio. Results: In men, only logarithm-transformed (log TG was associated with CKD. The odds ratio (every SD increment was 1.39 (95% CI 1.03–1.87, P = 0.03. In women, none of the serum lipids and lipid ratios was associated with CKD. Using multivariate regression models, it was shown that log TG and log TG/HDL-C were negatively correlated with eGFR (P < 0.05 in men and LDL-C and log LDL-C/HDL-C ratio were correlated with ACR in men. In female subjects, serum TC, log TG, log TG/HDL-C and log TC/HDL-C were negatively correlated with eGFR (P < 0.05. All of serum lipid profiles and lipid related ratio were not correlated with ACR in women. Conclusion: Serum TG is the only suitable predictor for CKD in men. However, in women, none of serum lipids and lipid ratio can be used as a predictor for CKD. Log TG and log TG/HDL-C are negatively correlated with eGFR in both genders.

    Full Text Available Context: The correlation of serum and salivary lipid profile has been poorly characterized. The most commonly used laboratory diagnostic procedures for lipid profile involve analysis of cellular and chemical constituents of blood/plasma. As a diagnostic aid, saliva offers many advantages over serum. Aims: To evaluate and compare the serum and salivary lipid profile levels in healthy individuals and to validate the role of saliva as a non-invasive diagnostic tool for assessing lipid profile. Settings and Design: The present study was a prospective study. Materials and Methods: A total of 100 healthy study subjects who had no complaint or any major illness in recent past were selected. The parameters assessed included serum and salivary: total cholesterol (TC, high-density lipoprotein-cholesterol (HDLC, low-density lipoprotein-cholesterol (LDLC, very low-density lipoprotein-cholesterol (VLDLC and triglycerides (TGL. Statistical Analysis Used: Evaluation of results and statistical analysis was carried out using descriptive, correlation and regression analysis. Results: There was a moderate level of correlation between serum and salivary TC, TGL, HDLC and VLDLC and there was a low and quite small correlation between serum and salivary LDLC. For all the five parameters assessed as a part of lipid profile, the correlation coefficients were highly significant statistically and also, with an increase in the serum mean values, corresponding increase in the saliva mean values for all the five parameters was noted. Conclusions: From the present study we conclude that saliva can be used as a non-invasive diagnostic tool for assessing lipid profile.

    Full Text Available Background and Objective: T3 resin uptake test indicates the availability of thyroxin binding globulin (TBG, which is the carrier of a large amount of T3 and T4 in blood. We aimed to study the relationship between serum T3 Resin Uptake and serum lipids profile. Material and Methods: The participants aged 14.80 ± 38.29 were both males (59; 29.5% and females (141; 70.5 %. T3 Resin Uptake was measured by Immunoassay method and serum lipid profile components (cholesterol, triglycerides, HDL-C, LDL-C, and VLDL were measured by the kit. Results: Significant negative correlation was observed between serum T3 Resin Uptake and cholesterol, triglycerides and LDL-C (P≤ 0.05, but that was not the case for HDL-C and VLDL. Conclusion: Serum T3 Resin Uptake can be evaluated to assess the risk factors related to cardiovascular disorders

    Full Text Available Regarding the high prevalence of hyperlipidaemia, which is one of the major risk factors of cardiovascular disease, and uncertain reports about the relation between periodontal disease and serum lipid profile, this study was conducted to assess this relation. The historical cohort study was conducted on 52 cases including 26 persons with chronic periodontitis as case group, and 26 healthy subjects as control group. Both groups had the same age and weight ranges, sex, and diet, without any periodontal treatment history in the past six months, underling systemic disease such as diabetes, anti-hyperlipidemic drugs or active tobacco smoking history. Low Density Lipoprotein (LDL, High Density Lipoprotein (HDL, Triglyceride (TG and Total Cholesterol (CHOL were measured by direct enzymatic assay. TG level was 128.4±71.1 mg/dl in control group and 165.2± 83.7 in case group indicating a significantly higher level in case group (P<0.05. In control group, 30.8 percent and in case group, 61.5 percent had abnormal serum cholesterol levels, which presents a significantly higher level in case group (P<0.03. Other serum level indices did not show any significant difference. Although it seems that patients with chronic periodontal disease are more susceptible to hyperlipidemia, it is doubtful that the former causes an increase in serum lipid levels, so we suggest studying the effects of treating chronic periodontitis on serum lipid level.

    Full Text Available Background: Infants of diabetic mothers (IDM is a critical issue in pediatrics, which is regarded as a major risk factor for birth trauma, respiratory distress syndrome (RDS, birth asphyxia, transient tachypnea of the newborn (TTN and jaundice. IDM is also a risk factor for microvascular (e.g., ocular and renal complications and macrovascular complications (e.g., cerebrovascular accident, atherosclerosis and cardiovascular complications. Lipids are a heterogeneous group of hydrophobic organic molecules which can be extracted from tissues using non-polar solvents. Lipids, due to their hydrophobic property, are mainly found in membranes enclosing various cell organelles. Diabetes mellitus management with insulin (nowadays also with oral hypoglycemic medications has improved the outcomes of gestational diabetes mellitus (GDM (most infants born to diabetic mother are large for gestational age. The neonatal mortality rate in IDM is over five times higher than that of infants of non-diabetic mothers. In this study, therefore, we aimed to assess the effect of maternal diabetes on cord serum lipid profile. Methods: This prospective (case-control study was carried out on 60 infants born in Al-Zahra teaching hospital during February 2014–October 2014. The study group consisted of 30 randomly chosen IDM, and the control group comprised 30 infants who were born to healthy mothers. Results: The results of this study demonstrated that there are significant differences between IDM and infants of healthy mothers regarding lipid profile and birth weight. Conclusion: This study confirms that cord serum lipid profile (serum cholesterol, serum triglycerides and low-density lipoprotein is higher at birth in IDM. Moreover, this study shows a significant association between lipid profile and body weight.

    Full Text Available Abstract Background It is well known that pulmonary alveolar proteinosis(PAP is characterised by accumulation of surfactant lipids and proteins within airspaces. However, few previous data describe the serum lipid levels associated with PAP. Materials and methods We retrospectively reviewed 25 patients with idiopathic PAP(iPAP. The serum lipid levels of patients with idiopathic PAP were compared with those of the healthy volunteers. In patients and healthy subjects, the LDL-C/HDL-C ratios were 2.94 ± 1.21 and 1.60 ± 0.70, respectively (p p A-aO2 (r = -0.685, p = 0.003, and r = 0.688, p = 0.003, respectively. The values of LDL-C/HDL-C ratios also correlated with PaO2 levels and PA-aO2 levels (r = -0.698, p = 0.003, and r = 0.653, p = 0.006, respectively. 11 and 13 patients experienced respectively a decline in TC and LDL-C levels following whole lung lavage(WLL, the median decline was 0.71 mmol/L(p p Conclusions the serum lipid levels, especially the levels of LDL-C and LDL-C/HDL-C, may reflect the severity of the disease in PAP patients, and predict the therapeutic effect of WLL.

    Full Text Available Background/Aim. Periodontitis is a local inflammatory process mediating destruction of periodontal tissues triggered by bacterial insult. However, this disease is also characterized by systemic inflammatory host responses that may contrbute, in part, to the recently reported increased risk for systemic diseases, including an altered lipid metabolism. On the other hand, many people in the world are affected by hyperlipidemia, which is a known risk faktor for atherosclerosis. The aim of this study was to determine the relationship between periodontal disease and blood lipid levels. Methods. A total of 50 patients with periodontitis included in this study had no documented history of recent acute coronary events. The healthy, non-periodontal subjects (comparison group comprised 25 subjects. All the patients were periodontology examined and completed a medical history. Dental plaque index, probing depth, gingival index bleeding on probing and clinical attechment levels were recorded. Blood samples were taken on admission for measurements of serum total cholesterol, triglycerides, hight density lipoprotein cholesterol (HDL-cholesterol, and low density lipoprotein cholesterol (LDL-cholesterol. Results. The obtained results showed that mean levels of cholesterol (6.09 ± 1.61 mmol/L, triglycerdes (2.19+1.67mmol/l and LDL cholesterol (4.09 ± 1.40 mmol/L in individuals with periodontitis were higer, and levels od HDL (1.43 ± 0.51 mmol/L was lower than those of individuals without periodontitis (4.86 ± 1.37; 1.14 ± 0.71; 3.18 ± 0.64; 1.53 ± 0.32 mmol/L, respectively. Conclusion. This study confirms a significant relationship between periodontal disease, regardless its intensity, and blood lipid levels in the studied population. The results imply that periodontitis may be a risk factor and may contribute to the pathogenesis of atherosclerosis and cardiovascular diseases (CVD. However, future prospective randomized studies have to determine whether

    Abstract Despite the well-documented role of calcium in cell metabolism, its role in the development of cardiovascular disease is still under heavy debate. Several studies suggest that calcium supplementation might be associated with an increased risk of coronary heart disease, whereas others underline a significant effect on lowering high blood pressure and hyperlipidemia. The purpose of this study was to investigate, in a large nonselected cohort from South Italy, if serum calcium levels correlate with lipid values and can therefore be linked to higher individual cardiovascular risk. Eight-thousand-six-hundred-ten outpatients addressed to the Laboratory of Clinical Biochemistry, University of Magna Græcia, Catanzaro, Italy from January 2012 to December 2013 for routine blood tests, were enrolled in the study. Total HDL-, LDL- and non-HDL colesterol, triglycerides, and calcium were determined with standard methods. We observed a significant association between total cholesterol, LDL-cholesterol, HDL-cholesterol, non-HDL cholesterol, triglycerides, and serum calcium in men and postmenopause women. Interestingly, in premenopause women, we only found a direct correlation between serum calcium, total cholesterol, and HDL-cholesterol. Calcium significantly increased while increasing total cholesterol and triglycerides in men and postmenopause women. Our results confirm that progressive increase of serum calcium level correlates with worsening of lipid profile in our study population. Therefore, we suggest that a greater caution should be used in calcium supplement prescription particularly in men and women undergoing menopause, in which an increase of serum lipids is already known to be associated with a higher cardiovascular risk.

    Leptin, a hormone from adipose tissue, regulates feeding behavior, satiation rate, energy expenditure and also plays an important role in maturation and reproduction. Recent studies support the concept that several factors such as a diet may influence on leptin levels. The aim of this study was to investigate serum concentration of leptin and lipids status in prepubertal children aged from 2 to 10 years with two different nutritional habits: vegetarian (n = 24) and omnivorous diet (n = 20). Serum leptin concentration was determined by immunoenzymeassay (ELISA). Serum lipids (cholesterol, HDL- and LDL-cholesterol, triglyceride) were measured by enzymatic and apolipoproteins by immunoturbidimetric methods. We noticed that in vegetarian diet there is a high rate of fiber (nearly twice as high as in omnivorous diet) and polyunsaturated acids (35% as much). In our study vegetarian children had lower total cholesterol and cholesterol in fractions HDL and LDL than meat eaters did. Also the apolipoproteins levels in vegetarian children were significantly below that of nonvegetarians. There is no differences in triglyceride concentration between the two groups of children. The mean serum leptin level in vegetarian children was significantly lower (3.1 +/- 1.2 ng/mL) as compared with the omnivores (5.6 +/- 2.1 ng/mL) (p < 0.0001).

  19. Effects of consumption of probiotics and prebiotics on serum lipid levels in humans.

    2002-01-01

    The objective of this article is to review existing studies concerning the effects of probiotics and prebiotics on serum cholesterol concentrations, with particular attention on the possible mechanisms of their action. Although not without exception, results from animal and human studies suggest a moderate cholesterol-lowering action of dairy products fermented with appropriate strain(s) of lactic acid bacteria and bifidobacteria. Mechanistically, probiotic bacteria ferment food-derived indigestible carbohydrates to produce short-chain fatty acids in the gut, which can then cause a decrease in the systemic levels of blood lipids by inhibiting hepatic cholesterol synthesis and/or redistributing cholesterol from plasma to the liver. Furthermore, some bacteria may interfere with cholesterol absorption from the gut by deconjugating bile salts and therefore affecting the metabolism of cholesterol, or by directly assimilating cholesterol. For prebiotic substances, the majority of studies have been done with the fructooligosaccharides inulin and oligofructose, and although convincing lipid-lowering effects have been observed in animals, high dose levels had to be used. Reports in humans are few in number. In studies conducted in normal-lipidemic subjects, two reported no effect of inulin or oligofructose on serum lipids, whereas two others reported a significant reduction in serum triglycerides (19 and 27%, respectively) with more modest changes in serum total and LDL cholesterol. At present, data suggest that in hyperlipidemic subjects, any effects that do occur result primarily in reductions in cholesterol, whereas in normal lipidemic subjects, effects on serum triglycerides are the dominant feature.

    Full Text Available Aim of our study was to investigate the effects of exposure to industrial noise on serum lipid profile among workers who are exposed to noise at work. In a historical cohort study, we recruited 154 and 146 male workers as high and low level noise exposure groups respectively. We defined workers with at least one year exposure to noise level more than 90 dB as high exposure group, and those with exposure to less than 80 dB as low exposure group. Afterwards, in the fasting blood specimens of participants we measured serum Triglyceride (TG, total Cholesterol (TC, high and low density lipoprotein (HDL and LDL. Mean of TG, TC, HDL and LDL for low exposure group were 148, 189, 38 and 103 mg/dl and for high exposure group were 237, 189, 37 and 104 mg/dl respectively. Mean serum TG between two groups was different. Even after adjustment for age, BMI, smoking and work hours per week, serum TG among high exposure group was 89 mg/dl higher than low exposure group and this difference was statistically significant (P=0.00. There was no significant difference between two groups in TC, LDL and HDL levels. This study did not find a statistically significant relationship between exposure to noise and serum TC, LDL and HDL, but TG in two groups was different and this difference was statistically significant.

    Full Text Available Introduction & Objective: Some investigators reported significant effect of garlic on serum cholesterol reduction. In addition, Iranian culture has specific belief on herbs and garlic in this regard. Our goal in this study was to evaluate the effect of garlet tablets on serum lipid profile.Materials & Methods: Sixty patients were randomly divided into two groups for evaluation of the effect of garlic on their lipid profile. The first group was low fat regimen group and the second was garlet tablet regimen group. Total cholesterol, LDL cholesterol, HDL cholesterol and triglyceride levels were measured in both groups. Then, after two months of these regimens administration, these items were measured again and were compared.Results: Mean age, sex and baseline initial lipid levels were similar in both groups. Total cholesterol and LDL cholesterol levels were decreased significantly in the garlic regimen group (in spite of non significant reduction in the other group. Triglyceride and HDL levels were not changed significantly in both regimen groups. Conclusion: Garlet tablet administration has more significant reductive effect on cholestrol level than low cholesterol diet.

    The serum lipid and lipoprotein levels of 59 obese Chinese children with a mean age of 13.0 years and mean relative weight of 164.2% were analysed. Between 40% to 54% of these children had elevated lipid and lipoprotein levels and about 78% had reduced high density lipoprotein (HDL) level when compared to healthy American and Japanese children. The obese children also had higher mean levels of total cholesterol (TC) and lower HDL compared to male adults in the local population. Those with elevated TC had higher mean relative weight (170% vs 159%, p obese children should be carefully screened and managed to prevent long term morbidity and mortality of coronary artery disease.

    Full Text Available Ischaemic Cerebrovascular Accident (CVA has been shown to be associated with abnormal lipid profile (dyslipidaemia as a risk factor. There is paucity of data regarding this in this environment hence this study. In this study, a total number of 63 subjects were recruited comprised of 33 patients with cerebrovascular accident (stroke and 30 apparently healthy volunteers as control. A complete lipid profile which included Total serum Cholesterol (TC, serum Triglyceride (TG, High Density Lipoprotein cholesterol (HDL-c and Low Density Lipoprotein cholesterol (LDL-c were assayed for both patients and controls. The lipid profile was determined using standard methods. The TC for both patients and control were 212±53 and 196±46 mg/dL respectively, TG for both patients and controls were 159±9 and 79±13 mg/dL respectively, HDL-c was 55±9 mg/dL for patients and 61±7 mg/dL for controls and LDL-c was 151±34 mg/dL for patients and 117±51 mg/dL for control subjects. TC, TG and LDL-c were higher in the ischaemic CVA patients than the controls; however only TG showed a significant increase while HDL-c although not significant was lower than control. The study therefore showed that ischaemic CVA is associated with hypercholesterolaemia, hypertriglyceridaemia and high LDL-cholesterol. We thus suggest preventive and management strategies that will reduce lipid levels (TC, TG and LDL and enhance HDL-cholesterol in Nigeria patients that are prone to or diagnosed of ischaemic CVA.

    Full Text Available Introduction: The effect of Tribulus terrestris (TT on serum glucose and lipid levels was investigated in an experimental model of diabetes mellitus in rats. Methods: Female Wistar rats were divided into control, TT-treated control, diabetic, glibenclamide-treated, and TT-treated diabetic groups. For induction of diabetes, streptozotcin (STZ was administered (60 mg/Kg. Meanwhile, TT-treated groups received TT mixed with standard pelleted food at a weight ratio of 6.25% for 6 weeks. Serum glucose and lipid levels were determined before the study and at the 3rd and 4th week after the study. Results: Serum glucose was significantly lower in TT-treated diabetic rats at 3rd and 6th weeks as compared to untreated diabetics (p<0.01 and p<0.005, respectively. In addition, serum total cholesterol, triglyceride, and LDL-cholesterol showed a significant reduction in TT-treated diabetic rats as compared to untreated diabetics (p<0.05. On the other hand, HDL-cholesterol level did not change significantly in TT-treated diabetic group as compared to untreated diabetic group. Conclusions: Oral administration of TT has a significant hypoglycemic effect and in long term leads to appropriate changes in serum LDL-cholesterol, total cholesterol, and triglyceride levels, but does not affect HDL-cholesterol levels in diabetic rats.

    Full Text Available Background: Nephrotic syndrome is a clinical entity with multiple causes characterized by increased glomerular permeability and manifested by massive proteinuria. Hyperlipidaemia has been found to be one of the cardinal manifestations of nephrotic syndrome. Aim: The present study was conducted to determine the lipid profile and cardiovascular risk of nephrotics in this locality. Methods: Serum total cholesterol (TC, triglycerides (TG, high density lipoprotein (HDL, low density lipoprotein (LDL, very low density lipoprotein (VLDL as well as atherogenic index (AI, coronary risk index (CRI and non-HDL cholesterol were determined in ninety-six subjects. Forty-eight were nephrotic patients while others were apparently healthy individuals used as controls. Result: TC, TG, and LDL-C of nephrotics was observed to be significantly higher (P0.05. HDL-C of nephrotics was observed to be significantly lower (P<0.05 when compared with control subjects. Conclusion: The result indicates apparent lipid derangement in nephrotic syndrome which may lead to cardiovascular disease. We therefore recommend that full lipid panel should be included in the investigation of suspected nephrotics to complement early diagnosis of the syndrome and to prevent further complications that could arise from the syndrome.

    Objectives:To see the effects of age, gender and diabetes on serum lipid levels. Study type, settings and duration:Cross sectional analytical study conducted at PMRC Research Centre, Fatima Jinnah Medical College,Lahore from Jun-Dec 2011. Materials and Methods: One hundred type 2 diabetes mellitus and equal numbers of gender matched healthy controls were randomly selected for the study. After an overnight fasting, blood specimens were drawn for lipid profile where total cholesterol,high density lipoprotein cholesterol and triglycerides were measured by standard enzymatic endpoint methods and LDL-cholesterol by Friedweld's formula. Statistical analysis was done using SPSS-15. Results Odd ratios of age for total cholesterol (OR 1.198); high density lipoprotein cholesterol (OR 1.144); and low density lipoprotein cholesterol (OR 1.576) revealed that subjects aged 45 years or more had greater risk of having deranged lipid levels. Female gender had higher high density lipoprotein cholesterol (p 0.000); and triglycerides (p 0.001). Odd ratios of men for total cholesterol (OR 0.775); high density lipoprotein cholesterol(OR 0.183); and low density lipoprotein Cholesterol (OR 0.683) illustrated that men were significantly less prone to dyslipidemia than women. Odd ratio of diabetes for high density lipoprotein cholesterol (OR 1.802) suggested that diabetics had 1.8 times more risk of having low high density lipoprotein cholesterol. Conclusions: Diabetic females over 45 years of age have significantly high chances of having disturbed or high lipid profile. Policy message:All persons in general and diabetics in particular over the age of 45 years should be screened for dyslipidemia and informed using behavior change communication to prevent disease complications.

    Lipids and the composition of lipoproteins in blood serum and liver cytosol, total lipid, and phospholipid contents in liver subcellular fractions and the spectrum of microsomal liver lipids were studied in male Wistar rats after a single injection of cobalt chloride. Virtually all lipid and lipoprotein fractions in blood and liver were increased and lipoprotein composition was changes. The lipid composition of liver microsomes did not change under these conditions. Thus, microsomal membranes are stable under developing oxidative stress. PMID:9331964

    Full Text Available BACKGROUND Diabetic retinopathy is one of the important microvascular complications of diabetes mellitus of long duration. Alterations in trace metals like magnesium and lipid profile was observed in diabetic retinopathy with hyperglycaemic status. AIM The study was taken up to assess the role of magnesium, lipid profile and glycated haemoglobin in diabetic retinopathy. MATERIALS AND METHODS A total of 80 subjects between 40-65 years were included in the study. Group 1 includes 20 age and sex matched healthy controls. Group 2 includes 30 cases of Diabetes mellitus without retinopathy. Group 3 includes 30 cases of Diabetes mellitus with retinopathy. RESULTS Magnesium was found to be significantly low in the diabetic group with retinopathy. Serum cholesterol and triglycerides were significantly elevated in the diabetic group with retinopathy. Fasting and Postprandial plasma glucose and glycated haemoglobin (HbA1c levels confirmed the glycaemic status of each of the groups. CONCLUSIONS Hypomagnesemia, hypercholesterolaemia, hypertriglyceridemia was observed in diabetic retinopathy along with increased levels of glycated haemoglobin in our study.

    Full Text Available Background. Despite extensive research and an improved standard of care, sepsis remains a disorder with a high mortality rate. Sepsis is accompanied by severe metabolic alterations. Methods. We evaluated 117 patients with sepsis (severe sepsis [n=19] and septic shock [n=98] who were admitted to the intensive care unit. Serum cholesterol, triglyceride (TG, high-density lipoprotein (HDL, low-density lipoprotein (LDL, free fatty acid (FFA, and apolipoprotein (Apo A-I levels were measured on days 0, 1, 3, and 7. Results. Nonsurvivors had low levels of cholesterol, TG, HDL, LDL, and Apo A-I on days 0, 1, 3, and 7. In a linear mixed model analysis, the variations in TG, LDL, FFA, and Apo A-I levels over time differed significantly between the groups (p=0.043, p=0.020, p=0.005, and p=0.015, resp.. According to multivariate analysis, TG levels and SOFA scores were associated with mortality on days 0 and 1 (p=0.018 and p=0.008, resp.. Conclusions. Our study illustrated that TG levels are associated with mortality in patients with sepsis. This may be attributable to alterations in serum lipid metabolism during sepsis, thus modulating the host response to inflammation in critically ill patients.

    Full Text Available Mutations in SPAST, encoding spastin, are the most common cause of autosomal dominant hereditary spastic paraplegia (HSP. HSP is characterized by weakness and spasticity of the lower limbs, owing to progressive retrograde degeneration of the long corticospinal axons. Spastin is a conserved microtubule (MT-severing protein, involved in processes requiring rearrangement of the cytoskeleton in concert to membrane remodeling, such as neurite branching, axonal growth, midbody abscission, and endosome tubulation. Two isoforms of spastin are synthesized from alternative initiation codons (M1 and M87. We now show that spastin-M1 can sort from the endoplasmic reticulum (ER to pre- and mature lipid droplets (LDs. A hydrophobic motif comprised of amino acids 57 through 86 of spastin was sufficient to direct a reporter protein to LDs, while mutation of arginine 65 to glycine abolished LD targeting. Increased levels of spastin-M1 expression reduced the number but increased the size of LDs. Expression of a mutant unable to bind and sever MTs caused clustering of LDs. Consistent with these findings, ubiquitous overexpression of Dspastin in Drosophila led to bigger and less numerous LDs in the fat bodies and increased triacylglycerol levels. In contrast, Dspastin overexpression increased LD number when expressed specifically in skeletal muscles or nerves. Downregulation of Dspastin and expression of a dominant-negative variant decreased LD number in Drosophila nerves, skeletal muscle and fat bodies, and reduced triacylglycerol levels in the larvae. Moreover, we found reduced amount of fat stores in intestinal cells of worms in which the spas-1 homologue was either depleted by RNA interference or deleted. Taken together, our data uncovers an evolutionarily conserved role of spastin as a positive regulator of LD metabolism and open up the possibility that dysfunction of LDs in axons may contribute to the pathogenesis of HSP.

    Nanolipoprotein particles (NLPs) consist of a discoidal phospholipid lipid bilayer confined by an apolipoprotein belt. NLPs are a promising platform for a variety of biomedical applications due to their biocompatibility, size, definable composition, and amphipathic characteristics. However, poor serum stability hampers the use of NLPs for in vivo applications such as drug formulation. In this study, NLP stability was enhanced upon the incorporation and subsequent UV-mediated intermolecular cross-linking of photoactive DiynePC phospholipids in the lipid bilayer, forming cross-linked nanoparticles (X-NLPs). Both the concentration of DiynePC in the bilayer and UV exposure time significantly affected the resulting X-NLP stability in 100% serum, as assessed by size exclusion chromatography (SEC) of fluorescently labeled particles. Cross-linking did not significantly impact the size of X-NLPs as determined by dynamic light scattering and SEC. X-NLPs had essentially no degradation over 48 h in 100% serum, which is a drastic improvement compared to non-cross-linked NLPs (50% degradation by ∼10 min). X-NLPs had greater uptake into the human ATCC 5637 bladder cancer cell line compared to non-cross-linked particles, indicating their potential utility for targeted drug delivery. X-NLPs also exhibited enhanced stability following intravenous administration in mice. These results collectively support the potential utility of X-NLPs for a variety of in vivo applications.

    Prenatal hyperandrogenism is hypothesized as one of the main factors contributing to the development of polycystic ovary syndrome (PCOS). PCOS patients have high risk of developing fatty liver and steatosis. This study aimed to evaluate the role of prenatal hyperandrogenism in liver lipid metabolism and fatty liver development. Pregnant rats were hyperandrogenized with testosterone. At pubertal age, the prenatally hyperandrogenized (PH) female offspring displayed both ovulatory (PHov) and anovulatory (PHanov) phenotypes that mimic human PCOS features. We evaluated hepatic transferases, liver lipid content, the balance between lipogenesis and fatty acid oxidation pathway, oxidant/antioxidant balance and proinflammatory status. We also evaluated the general metabolic status through growth rate curve, basal glucose and insulin levels, glucose tolerance test, HOMA-IR index and serum lipid profile. Although neither PH group showed signs of liver lipid content, the lipogenesis and fatty oxidation pathways were altered. The PH groups also showed impaired oxidant/antioxidant balance, a decrease in the proinflammatory pathway (measured by prostaglandin E2 and cyclooxygenase-2 levels), decreased glucose tolerance, imbalance of circulating lipids and increased risk of metabolic syndrome. We conclude that prenatal hyperandrogenism generates both PHov and PHanov phenotypes with signs of liver alterations, imbalance in lipid metabolism and increased risk of developing metabolic syndrome. The anovulatory phenotype showed more alterations in liver lipogenesis and a more impaired balance of insulin and glucose metabolism, being more susceptible to the development of steatosis.

    Prospective evidence on the extent to which serum lipid concentrations in older persons respond to dietary modification is scarce. It is not clear whether such behavioral changes are relevant in the context of more commonly initiated treatments with lipid-lowering drugs. We therefore examined whether individual changes in the consumption of dietary fatty acids or main food sources were associated with changes in the serum lipid profile of older Australians. A total of 903 participants (> or =49 y) in the Blue Mountains Eye Study had complete data on fasting lipids and dietary intake from a validated FFQ at baseline (1992-1994) and 5- and 10-y follow-up examinations. Decreasing consumption of SFA and butter during the 10-y period were associated with moderate decreases in serum total cholesterol independently of initiation of lipid-lowering drug treatment [adjusted estimates were 0.018 +/- 0.007 mmol/(L x % energy (%en) from SFA (P = 0.01) and 0.055 +/- 0.015 mmol/(L x 5 g butter) (P = 0.0003), respectively]. Increased consumption of (n-3) fatty acids and fish was independently related to modest increases in serum HDL-cholesterol [0.067 +/- 0.026 mmol/(L x %en from (n-3) fatty acids) (P = 0.01) and 0.010 +/- 0.004 mmol/(L x 20 g fish) (P = 0.02)] and decreases in log-transformed serum triglyceride concentrations [P = 0.02 for (n-3) fatty acids and P = 0.02 for fish intake]. Hence, 10-y changes in the intake of dietary fatty acids and their food sources appear to have contributed to concurrent improvements in the serum lipid profile of older Australians, independent of concomitantly initiated lipid-lowering drug treatment.

    Objective To evaluate some risk factors for cardiovascular diseases in feeding and eating disorders, the degree of lipid abnormalities was investigated in a large Japanese cohort of different groups of feeding and eating disorders, according to the Japan Atherosclerosis Society Guidelines for the Prevention of Atherosclerotic Cardiovascular Diseases 2012 (JAS Guidelines 2012). Methods Participants in the current study included 732 women divided into four groups of feeding and eating disorders: anorexia nervosa, restricting type (AN-R); anorexia nervosa, binge-eating/purging type; bulimia nervosa (BN); and binge-eating disorder (BED). We measured the serum levels of total cholesterol, high-density-lipoprotein (HDL) cholesterol, and triglyceride in these participants. Low-density-lipoprotein (LDL) cholesterol and non-HDL cholesterol levels were also calculated. Results The concentrations of LDL cholesterol and non-HDL cholesterol were widely distributed in all groups. When the LDL cholesterol risk was defined as ≥120 mg/dL and the non-HDL cholesterol risk as ≥150 mg/dL, according to the JAS Guidelines 2012, the proportion of LDL cholesterol risk ranged from 29.6% (BN) to 38.6% (AN-R), and the proportion of non-HDL cholesterol risk ranged from 17.8% (BN) to 30.1% (BED). Conclusion The present findings suggest the existence of LDL cholesterol risk and non-HDL cholesterol risk in all groups of eating disorders. Given the chronicity of this condition, the development of elevated concentrations of LDL cholesterol and non-HDL cholesterol at an early age may increase the risk of cardiovascular diseases.

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    This study looks into the influence of cosmic radiation at high altitudes on human bodies. Results reveal that the cytokinesis-block micronuclei (CBMN) and conventional cultured micronuclei in peripheral blood lymphocytes, serum levels of lipid peroxide, superoxide dismutase, and the total antioxidation capacity by chemical colorimetry all increased significantly in aircrew members. There exists a linear relationship between the CBMN and the average annual effective doses of radiation received or the average annual flying hours. With both of them, a trend shows that the serum lipid peroxide levels increase as well. Either the lipid peroxide or CBMN can sensitively reflect the recent changes in flight load. These findings indicate that cosmic radiation impairs the stability of chromosomes and genome, and induces lipid oxidative damage in aircrews; Lymphocyte CBMN and serum lipid peroxide can be used as monitoring indicators in the cosmic radiation protection for aircrew members.

    Full Text Available Cadmium (Cd is an environmental toxic metal implicated in lipid abnormalities. The present study was designed to elucidate the possible association between chronic exposure to Cd concentration and alterations in plasma lipid, lipoprotein, and oxidative stress indices in rats. Sixteen male rats were assigned to 2 groups of 8 rats each (test and control. The Cd-exposed group obtained drinking water containing cadmium chloride (CdCl2 in the concentration of 2.0 mg Cd/L in drinking water for 3 months. At the end of the experimental period, blood samples were obtained to determine the changes of serum triglycerides (TG, total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C, reduced glutathione (GSH, malondialdehyde (MDA and also serum Cd contents. The results of the present study indicated that Cd administration significantly increased the serum levels of TG, TC, LDL-C, MDA and Cd with reduction in the HDL-C and GSH levels. In conclusion, evidence is presented that chronic exposure to low Cd concentration can adversely affect the lipid and lipoprotein profile via lipid peroxidation.

    We have previously reported that high-fat diets develop hepatic steatosis and, depending on the fat quality, affect serum lipid levels differently (J Nutr Sci Vitaminol, 1997, 43, 155-160). The aim of this work is to study the influence of high-fat diets (14% sunflower or olive oils) on serum lipids in a model of hepatic acute damage induced by thioacetamide, and their influence when dexamethasone is administered before thioacetamide injection. Serum lipids and hepatic collagen have been evaluated using biochemical methods, and the steatotic process by histological staining. The results showed that hepatic steatosis and fibrosis are developed either by high-fat diets or thioacetamide injection. Pretreatment with dexamethasone did not decrease the hepatic collagen content. Thioacetamide injection alone or pretreatment with dexamethasone produced increase in serum tryglicerides (TG), total cholesterol (TC) and LDL-C in both high-fat diet groups, and a HDL-C increase in the olive-oil group, even though the atherogenic indices (HDL/TC and HDL/TG) were different depending on the enriched diet. The administration of high-fat diets to study the influence of the fat quality on health and disease should be interpreted carefully due to the ability of the diets themselves to cause hepatic damage.

    In biophysical and biochemical studies of lipid bilayers the influence of the used buffer is often ignored or assumed to be negligible on membrane structure, elasticity, or physical properties. However, we here present experimental evidence, through bending rigidity measurements performed on giant...... vesicles, of a more complex behavior, where the buffering molecules may considerably affect the bending rigidity of phosphatidylcholine bilayers. Furthermore, a synergistic effect on the bending modulus is observed in the presence of both salt and buffer molecules, which serves as a warning...... to experimentalists in the data interpretation of their studies, since typical lipid bilayer studies contain buffer and ion molecules....

    Animal studies have suggested that CLA, a natural component of meat and dairy products, may confer beneficial effects on health. However, human studies using supplementation with CLA have produced contradictory results. The aim of the present study was to further investigate the effect of CLA supplementation on human body fat, serum leptin, and serum lipids, as well as the incorporation of CLA isomers into serum lipids classes. Sixteen young healthy nonobese sedentary women received 2.1 g of CLA (divided equally between the cis,trans-9,11 and trans,cis-10,12 isomers) daily for 45 d and placebo for 45 d in a randomized double-blind crossover design. Body fat was estimated (by measurement of skinfold thickness at 10 sites), and blood was sampled at the beginning, middle, and end of the entire intervention period; an additional blood sample was obtained 2 wk thereafter. No significant differences in energy, carbohydrate, lipid, or protein intake existed between the CLA and placebo intake periods. No significant differences were found in body fat or serum leptin, TAG, total cholesterol, HDL-cholesterol, and alanine aminotransferase between CLA and placebo. The CLA isomer content of serum TAG, phospholipids, and total lipids increased 2-5 times with CLA supplementation (P lipids. These data indicate that supplementation with 2.1 g of CLA daily for 45 d increased its levels in blood but had no effect on body composition or the lipidemic profile of nonobese women.

    Full Text Available Dry lecithin, which is a mixture of polar phospholipids, neutral lipids, free fatty acids, glycolipids, carbohydrates, and small amounts of moisture, is a promising object for biologic-hepatoprotectors creation. One of its pharmacological activity displays is its influence on serum lipids, in particular transport forms of these lipids. The influence of dry soy lecithin and sunflower on hyperlipoproteinemia ratio and other lipid disorders is studied. It is shown that low-fat dry soybean lecithin showed hypocholesterolemic activity against all studied forms of serum cholesterol. Nonfat dry sunflower lecithin had similar but somewhat less prominent effect. However reduced concentration of high density lipoprotein cholesterol under sunflower lecithin developed right before soya lecithin. Both lecithin prevented the development of dyslipidemia induced carbon tetrachloride.

    Full Text Available Background: Preeclampsia is a pregnancy-specific disease associated with significant maternal and perinatal mortality and morbidity. Lipid abnormality and elevated serum uric acid have been reported as early features of the disease. We aimed to detect the level of serum lipid profile and uric acid abnormalities in severe preeclamptics in Benin City and to measure their clinical significance. Materials and Methods: A prospective case-control study was conducted with subjects presenting with severe preeclampsia to the Obstetric Unit of the UBTH, Benin City. Fasting serum lipid profile and uric acid levels of 40 severe preeclamptic subjects and 80 gestation-matched normotensive controls were done at recruitment. The preeclamptic subjects were managed according to our departmental protocol which included stabilisation and delivery. Their sociodemographic and clinical characteristics were used to generate a database for analysis. Results: The mean serum uric acid level was 28% higher in severe preeclamptics than normotensive women (5.96 ± 2.54 mg/dl versus 4.30 ± 0.85; P = 0.005. There were statistically significant differences in levels of triglycerides (TG, low-density lipoprotein (LDL and high-density lipoprotein (HDL between the preeclamptics and their normotensive controls (P = 0.006, P = 0.000, P = 0.000, respectively. Abnormal serum uric acid was associated with advanced maternal age (P = 0.000, early-onset preeclampsia (P = 0.000 and abnormal body mass index (BMI; P = 0.000. Low birth weight was more likely in preeclamptics with elevated serum uric acid levels (P = 0.041. Conclusion: Abnormality of serum uric acid in preeclampsia was significantly associated with increased frequency of complications but lipid profile abnormalities were not shown in the subjects studied. We recommend a larger scale study to determine lipid profile in normal and complicated pregnancies in our environment.

    Full Text Available Objective: Serum lipid levels are not only associated with etiology, but also with prognosis in cancer. To investigate this issue further, we aimed to evaluate the serum levels of lipids in association with the most important prognostic indicators in cancer patients at the start of chemotherapy. Methods: In a retrospective cross-sectional study, using existing medical records obtained from 2009–2014, the data of all incident cancer cases in Iranian patients referred to the Semnan oncology clinic for chemotherapy were analyzed. Data on demographics, cancer type, prognostic indicators (e.g. lymph node involvement, metastasis, and stage of disease, as well as the patient’s lipid profile were collected. We used multiple logistic regression models to show the relationship between prognosis indicators and lipid profile adjusting for age, gender, and type of cancer. Results: The data of 205 patients was gathered. We found a significant difference in the lipid profile between different types of cancers (breast, colon, gastric, and ovarian. With the exception of high-density lipoprotein levels in women, which were higher than in men, the means of other lipid profiles were similar between the genders. There was a significant association between higher levels of low-density lipoprotein (LDL >110mg/dL in the serum and metastasis (adjusted odds ratio=2.4, 95% CI 1.2–3.5. No significant association was reported between lipid profile and lymph nodes involvement and stage of the disease. Conclusion: Our study suggested a benefit of measuring serum levels of lipids for predicting cancer progression. Increased LDL levels can be considered a predictive factor for increasing the risk of metastasis.

    Reproductive factors have been shown to correlate with lipid metabolism. The aim of this study was to investigate the relationship between parity and serum lipid levels in community-based Chinese female adults. A total of 4,217 female participants were enrolled. Parity was recorded according to questionnaire and serum lipid profile, including triglycerides (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C), was measured. Logistic regression models were used to analyze the association of parity to serum lipid levels, while adjusting for demographics and metabolic risk factors. Parity in this population ranged from 0 to 7. After adjusting for potential confounders, it indicated that females with more than 2 parities appeared to be less likely to suffer from abnormal serum TC level compared with nulliparae (parity = 2, odds ratio (OR) = 0.457, 95% confidence interval (CI) = 0.284-0.736; parity ≥ 3, OR = 0.363, 95% CI = 0.202-0.653). These findings suggested that parity could correlate with lipid metabolism in Chinese women. Individuals with higher parity appeared to have a lower total cholesterol in blood. PMID:27645134

    Data on coffee consumption were collected for 1074 adults attending for health checks in the OXCHECK study, to assess associations with serum lipids and blood pressure. Of the sample, 70.5% drank coffee, largely instant. Coffee had no significant effects on total or high-density lipoprotein (HDL) cholesterol or blood pressure, and was negatively correlated with serum triglycerides. The type of coffee drunk in the UK does not adversely effect these cardiovascular risk factors.

    Full Text Available BACKGROUND: Six new cationic gemini lipids based on cholesterol possessing different positional combinations of hydroxyethyl (-CH2CH2OH and oligo-oxyethylene -(CH2CH2On- moieties were synthesized. For comparison the corresponding monomeric lipid was also prepared. Each new cationic lipid was found to form stable, clear suspensions in aqueous media. METHODOLOGY/PRINCIPAL FINDINGS: To understand the nature of the individual lipid aggregates, we have studied the aggregation properties using transmission electron microscopy (TEM, dynamic light scattering (DLS, zeta potential measurements and X-ray diffraction (XRD. We studied the lipid/DNA complex (lipoplex formation and the release of the DNA from such lipoplexes using ethidium bromide. These gemini lipids in presence of a helper lipid, 1, 2-dioleoyl phophatidyl ethanol amine (DOPE showed significant enhancements in the gene transfection compared to several commercially available transfection agents. Cholesterol based gemini having -CH2-CH2-OH groups at the head and one oxyethylene spacer was found to be the most effective lipid, which showed transfection activity even in presence of high serum levels (50% greater than Effectene, one of the potent commercially available transfecting agents. Most of these geminis protected plasmid DNA remarkably against DNase I in serum, although the degree of stability was found to vary with their structural features. CONCLUSIONS/SIGNIFICANCE: -OH groups present on the cationic headgroups in combination with oxyethylene linkers on cholesterol based geminis, gave an optimized combination of new genera of gemini lipids possessing high transfection efficiency even in presence of very high percentage of serum. This property makes them preferential transfection reagents for possible in vivo studies.

    Within the European Union, the provision of dustbathing material in layer housing systems will be compulsory beginning in 2012. In cage systems, food particles are mainly used as litter material and are provided on scratching mats by an automatic transporting system. However, because dustbathing is a means for hens to remove stale lipids from their plumage, lipid content of a substrate may be an important asset with regard to its adequacy. This study analyzes dustbathing behavior as affected by lipid content of feed used as litter material. A total of 72 laying hens of 2 genotypes (Lohmann Selected Leghorn, Lohmann Brown) were kept in 12 compartments (6 hens each). Compartments were equipped with a plastic grid floor (G) and additionally contained 3 different dustbathing trays (each 1,000 cm(2)/hen) holding low-lipid (0.82%; L), normal-lipid (4.2%; N), and high-lipid (15.7%; H) food particles. The experiment began at 20 wk of life, and video recordings were done at wk 23, 26, and 29. Number of dustbaths, time spent dustbathing, average dustbath duration, foraging, and single behaviors within dustbaths were analyzed during the light period over 2 d in each observation week. Dustbaths occurred most frequently in the L compared with the N, H, and G treatments (all P < 0.001). Total time spent dustbathing was longest in the L treatment compared with the N and H treatments (P < 0.001). No difference in the average duration of single dustbaths was found between the L, N, and H treatments. However, when dustbath interruptions (less than 10 min) were excluded, the duration of single dustbaths was longer in the H compared with the L (P = 0.009) and N (P = 0.024) treatments. Foraging was most frequently observed in the N compared with the L, H, and G treatments (all P < 0.001). More body wing shakes occurred in the L compared with the N treatment, and the number of vertical wing shakes was higher in the N compared with the H treatment (all P ≤ 0.05). Our results showed

    We assessed the secular trends in the serum lipid levels in Shanghai residents from 1973 to 1999. Data from four independent, cross-sectional, population-based surveys were used to analyze the trends in serum lipid levels from 1973 to 1999. A standard protocol was applied across each survey in at least three independent surveys which were separated a 10-year study period. A total of 10733 (1385, 3302, 2399, and 3647 subjects who had complete data on serum lipids in 1973-1974, 1982, 1983 and 1997-1999, respectively) Shanghai residents aged from newborn to 80 years old were enlisted at random. Serum lipid levels were measured in a single laboratory throughout the entire study period. A non-significant increase was noted from 1973-1974 to 1982-1983 in the serum lipid profiles; however, a significant increase was observed from 1982-1983 to 1997-1999 in most of the age groups of both sexes. Mean serum total cholesterol (TC) levels increased significantly (P 40 it was from 5.5% to 11.57%. In females, it was 0 to 4.68% and 6.5% to 16.2%, respectively. In general, the trends in the levels of TC, TG and LDL-c were increasing and trends in the levels of HDL-c were decreasing in most age groups, especially, in the younger age group of Shanghai residents from 1980s to 1990s. These worrying findings are significant for its public health implications. Health education and health pro-motion are necessary to prevent the disease prevalence from rising in the Chinese population.

    Obesity, a chronic low-grade inflammatory condition is associated with the development of many comorbidities including dyslipidemia. This review examines interactions between single nucleotide polymorphisms (SNP) in the inflammatory genes tumor necrosis alpha (TNFA) and interleukin-6 (IL-6) and dietary fatty acids, and their relationship with obesity and serum lipid levels. In summary, dietary fatty acids, in particular saturated fatty acids and the omega-3 and omega-6 polyunsaturated fatty acids, impact the expression of the cytokine genes TNFA and IL-6, and alter TNFα and IL-6 production. In addition, sequence variants in these genes have also been shown to alter their gene expression and plasma levels, and are associated with obesity, measures of adiposity and serum lipid concentrations. When interactions between dietary fatty acids and TNFA and IL-6 SNPs on obesity and serum lipid were analyzed, both the quantity and quality of dietary fatty acids modulated the relationship between TNFA and IL-6 SNPs on obesity and serum lipid profiles, thereby impacting the association between phenotype and genotype. Researching these diet-gene interactions more extensively, and understanding the role of ethnicity as a confounder in these relationships, may contribute to a better understanding of the inter-individual variability in the obese phenotype.

    Objectives To explore the homocysteine's risk to atherosclerosis and its correlations with serum lipids TG,TG and HDL-C. Methods With a cross sectional study, 490 subjects (aged 41-86 yrs, male 420 and female 70) were surveyed in 1999 in Guangdong Province, China. The main research variables were homocysteine (Hcy) and the serum lipids total cholesterol (TC), triglyceride (TG),high-density lipoprotein cholesterol(HDL-C). Results Hcy was a possible risk factor resulting in atherosclerosis (OR=l.15, 0.05 <P <0.10, n=108) with Logistic regression analysis. There is no correlation or much lower degree correlation between Hey and the serum lipids group of TC, TG, HDL-C. The canonical correlation coefficient between V1 and W1 was R1,Can =0.12(0.05<P<0.10, n=490, V1=Hcy, W1= - 0.9446 * TC + 0.1588 * TG + 0.6009 * HDL-C). Conclusions It is possible that Hcy is a risk factor to atherosclerosis and is independent of serum lipids group or has much lower correlation with it. It is necessary to do more research to explore the risk degree of Hcy inducing atherosclerosis and whether are there are bigger correlations or higher independence between Hcy and other risk factors during the progress of atherosclerosis.

    2009-07-01

    Full Text Available Abstract Background The metabolic syndrome (MetS is a cluster of metabolic abnormalities comprising visceral obesity, dyslipidaemia and insulin resistance (IR. With the onset of IR, the expression of lipoprotein lipase (LPL, a key regulator of lipoprotein metabolism, is reduced. Increased activation of glucocorticoid receptors results in MetS symptoms and is thus speculated to have a role in the pathophysiology of the MetS. Glycyrrhizic acid (GA, the bioactive constituent of licorice roots (Glycyrrhiza glabra inhibits 11β-hydroxysteroid dehydrogenase type 1 that catalyzes the activation of glucocorticoids. Thus, oral administration of GA is postulated to ameliorate the MetS. Results In this study, daily oral administration of 50 mg/kg of GA for one week led to significant increase in LPL expression in the quadriceps femoris (p p > 0.05 of the GA-treated rats compared to the control. Decrease in adipocyte size (p > 0.05 in both the visceral and subcutaneous adipose tissue depots accompanies such selective induction of LPL expression. Consistent improvement in serum lipid parameters was also observed, with decrease in serum free fatty acid, triacylglycerol, total cholesterol and LDL-cholesterol but elevated HDL-cholesterol (p > 0.05. Histological analysis using tissue lipid staining with Oil Red O showed significant decrease in lipid deposition in the abdominal muscle and quadriceps femoris (p p > 0.05. Conclusion Results from this study may imply that GA could counteract the development of visceral obesity and improve dyslipidaemia via selective induction of tissue LPL expression and a positive shift in serum lipid parameters respectively, and retard the development of IR associated with tissue steatosis.

    Concentrations of serum lipid components, lipid peroxide (LPO) and alpha-tocopherol and electrophoretic patterns of lipoproteins in serum samples obtained from captive marine mammals and terrestrial mammals were compared. Serum concentrations of total cholesterol, free fatty acid, and phospholipid in fish-eating animals were significantly higher than those in manatees and cows. Serum LPO and alpha-tocopherol concentrations in the fish-eating animals were also significantly higher than those in manatees, cows and dogs. Different patterns of densitometric scans of low density lipoprotein (LDL) and a significantly lower percentage of LDL were demonstrated in the dolphins compared with the seals, cow and dogs. The concentration of LPO was significantly correlated with triglyceride and phospholipid concentrations in serum from the dolphins. These results suggest that triglyceride and phospholipid are susceptible to oxidative reaction in fish-eating animals. Evaluation of serum lipids, LPO and alpha-tocopherol concentrations is needed for nutritional husbandry for fish-eating animals.

    Full Text Available Abstract Background Humans and animals show a certain consistency in the response of their serum lipids to fat-modified diets. This may indicate a genetic basis underlying this response. Coffee oil might be used as a model substance to investigate which genes determine differences in the serum lipid response. Before carrying out such studies our objective was to investigate to what extent the effect of coffee oil on serum lipid concentrations is reproducible within subjects. Methods The serum lipid response of 32 healthy volunteers was measured twice in separate five-week periods in which coffee oil was administered (69 mg cafestol / day. Results Total cholesterol levels increased by 24% in period 1 (range:0;52% and 18% in period 2 (1;48%, LDL cholesterol by 29 % (-9;71% and 20% (-12;57%, triglycerides by 66% (16;175% and 58% (-13;202%, and HDL cholesterol did not change significantly: The range of the HDL response was -19;25% in period 1 and -20;33% in period 2. The correlation between the two responses was 0.20 (95%CI -0.16, 0.51 for total cholesterol, 0.16 (95%CI -0.20, 0.48 for LDL, 0.67 (95%CI 0.42, 0.83 for HDL, and 0.77 (95%CI 0.56, 0.88 for triglycerides. Conclusions The responses of total and LDL cholesterol to coffee oil were poorly reproducible within subjects. The responses of HDL and triglycerides, however, appeared to be highly reproducible. Therefore, investigating the genetic sources of the variation in the serum-lipid response to coffee oil is more promising for HDL and triglycerides.

    Full Text Available An in vivo trial was conducted to evaluate the effects of Bacillus coagulans, and inulin, either separately or in combination, on lipid profile using a rat model. Thirty-two male Wistar rats were randomly divided into four groups (n=8 and fed as follows: standard diet (control, standard diet with 5% w/w long chain inulin (prebiotic, standard diet with 109 spores/day spores of B. coagulans by orogastric gavage (probiotic, and standard diet with 5% w/w long chain inulin and 109 spores/day of B. coagulans (synbiotic. Rats were fed for 30 days. Serum samples were collected 10, 20 and 30 days following onset of treatment. Total, HDL and LDL cholesterol and triglycerides concentrations were analyzed. Results of this study showed that inulin potentially affected the lipid profile. An obvious decrease in serum total cholesterol and LDL-cholesterol of rats fed with inulin in symbiotic and prebiotic groups was seen in all sampling days. Inulin fed rats also demonstrated higher levels of HDL-cholesterol concentration; however this value in probiotic and control fed rats remains without significant change. According to the results of this study, B. coagulans did not contribute to any lipid profile changes after 30 days. Thus, further in vitro investigations on the characteristic of these bacteria could be useful to gain insights into understanding the treatment of probiotics in order to achieve the maximum beneficial effect.

  12. Human serum activates CIDEB-mediated lipid droplet enlargement in hepatoma cells

    International Nuclear Information System (INIS)

    Highlights: •Human serum induced differentiation of hepatoma cells increases cellular lipid droplet (LD) size. •The observed increase in LD size correlates with increased PGC-1α and CIDEB expression. •Induction of CIDEB expression correlates with rescue of VLDL secretion and loss of ADRP. •siRNA knockdown of CIDEB impairs the human serum mediated increase in LD size. •This system represents a cost-efficient model to study CIDEB’s role in lipid biology. -- Abstract: Human hepatocytes constitutively express the lipid droplet (LD) associated protein cell death-inducing DFFA-like effector B (CIDEB). CIDEB mediates LD fusion, as well as very-low-density lipoprotein (VLDL) maturation. However, there are limited cell culture models readily available to study CIDEB’s role in these biological processes, as hepatoma cell lines express negligible levels of CIDEB. Recent work has highlighted the ability of human serum to differentiate hepatoma cells. Herein, we demonstrate that culturing Huh7.5 cells in media supplemented with human serum activates CIDEB expression. This activation occurs through the induced expression of PGC-1α, a positive transcriptional regulator of CIDEB. Coherent anti-Stokes Raman scattering (CARS) microscopy revealed a correlation between CIDEB levels and LD size in human serum treated Huh7.5 cells. Human serum treatment also resulted in a rapid decrease in the levels of adipose differentiation-related protein (ADRP). Furthermore, individual overexpression of CIDEB was sufficient to down-regulate ADRP protein levels. siRNA knockdown of CIDEB revealed that the human serum mediated increase in LD size was CIDEB-dependent. Overall, our work highlights CIDEB’s role in LD fusion, and presents a new model system to study the PGC-1α/CIDEB pathway’s role in LD dynamics and the VLDL pathway

    Full Text Available Lipids have a key role in the maintenance of cell integrity. Hypolipidemia is related with increased risk of cancer and mortality. Elevated calcium and alkaline phosphatase has also been seen in cancer patients having m etastasis. Alteration in serum prote ins also has been reported. Hence present study was undertaken in 100 histopathologically confirmed head and neck cancer patients, in Department of Pathology Gandhi Medical College Bhopal, after taking informed written c onsent and ethical clearance. Lipid Profile, Serum Calcium, Alkaline Phosphatase, Serum Protein with Albumin were estimated and compared with age and sex matched healthy controls. Statistical analysis was done using chi square test. Total cholesterol (TC, high density lipoprotein - cholesterol (HDLC, low density lipoprotein - cholesterol (LDLC, Very low density lipoprotein - cholesterol (VLDLC all decreased in head & neck cancer patients. Hypercalcemia was seen in 35% of patients. Raised Alkaline phosphatase (ALP was seen in 8 % cancer patients. Serum calcium was found to be increasing with advancing stage. Further studies should be carried out in large number of patients to confirm the role of these parameters with special attention to modifiable ones and their relation with staging and grading of cancer, which can be used as prognostic markers.

    The present study was carried out to measure lipid and protein levels in serum of healthy women during treatment with a new oral contraceptive combination containing 0.075 mg desogestrel (Org 2969, 17 alpha-ethinyl-18-methyl-11-methylene-4-estren-17-ol) plus 0.050 mg ethinyloestradiol per tablet. All 30 volunteers took 1 tablet daily for 21 consecutive days, followed by a tablet-free period of 7 days. Treatment lasted 3 months. At the end of treatment serum total cholesterol had increased by 0.26 mmol/l (5.0%), high-density lipoprotein-cholesterol by 0.22 mmol/l (15.2%) and triglycerides by 0.43 mmol/l (50%); the calculated low-density lipoprotein cholesterol had decreased by 0.16 mmol/l (4.9%). All lipid concentrations had returned to initial levels 2 months after treatment stopped. After 3 months treatment serum ceruloplasmin, cortisol-binding globulin capacity, sex-hormone-binding globulin capacity and thyroxine-binding globulin had significantly increased by 85.2, 133, 206 and 101%, respectively. All protein levels returned to normal 2 months after treatment stopped. The relationship between serum lipids and hormone-binding proteins has been discussed, as well as the significance of the high-density lipoprotein level with regard to contraceptive treatment.

  15. Relationship between abdominal fat distribution assessed by computed tomography and serum lipids in the elderly

    International Nuclear Information System (INIS)

    A nutritional assessment is necessary to evaluate the pathophysiological state of patients, and serum lipids are one of the factors which must be evaluated. Body fat distribution is considered to be associated with cardiac diseases, metabolic diseases and hypertension. In this study, we performed quantitative measurements of fat distribution by X-ray computed tomography (CT) in 31 elderly outpatients. Thirteen men (mean age 74.8 years) and 18 women (mean age 75.4 years) were examined by abdominal CT. All subjects had body mass indices within the normal range and did not have malignant disease, hyperlipidemia, liver dysfunction or diabetes mellitus. CT scans were carried out at the level of the middle abdomen, these scan slices included intraabdominal fat which consisted of omental retroperitoneal and perirenal adipose tissues. Subcutaneous fat areas and intraabdoinal fat areas were measured from six 10-mm-thick slice films using a 2-dimensional computerized calculator. The relationship between serum lipids and fat distribution was also examined. The ratio of intraabdominal adipose tissue area to subcutaneous adipose tissue area (V/S) was higher in men than women. V/S correlated positively with serum triacylgycerol and correlated negatively with serum HDL-Ch. These results suggest that the measurement of body fat distribution is important to evaluate lipid metabolism and nutritional states in the elderly. (author)

    The aim of this study was to investigate the effects of taurine (TA) on serum lipid profiles following chronic coadministration of chlorpyrifos (CP) and lead acetate (Pb) in male Wistar rats. Fifty rats randomly distributed into five groups served as subjects. Distilled water (DW) was given to DW group, while soya oil (SO; 1 mL kg(-1)) was given to SO group. The TA group was treated with TA (50 mg kg(-1)). The CP + Pb group was administered sequentially with CP (4.25 mg kg(-1); 1/20th median lethal dose (LD50)) and Pb at 233.25 mg kg(-1) (1/20th LD50), while the TA + CP + Pb group received TA (50 mg kg(-1)), CP (4.25 mg kg(-1)), and Pb (233.25 mg kg(-1)) sequentially. The treatments were administered once daily by oral gavage for 16 weeks. The rats were euthanised, and the blood samples were collected at the termination of the study. Sera obtained from the blood samples were analyzed for total cholesterol, high-density lipoprotein cholesterol, triglycerides, and malondialdehyde, and also the activities of serum antioxidant enzymes including superoxide dismutase, catalase and glutathione peroxidase were analyzed. The low-density lipoprotein cholesterol, very-low-density lipoprotein cholesterol, and atherogenic index were calculated. The results showed that CP and Pb induced alterations in the serum lipid profiles and evoked oxidative stress. TA alleviated the disruptions in the serum lipid profiles of the rats partially by mitigating oxidative stress. It was concluded that TA may be used for prophylaxis against serum lipid disorders in animals that were constantly co-exposed to CP and Pb in the environment. PMID:25537622

    The regular consumption of flavonoids has been associated with reduced mortality and a decreased risk of cardiovascular diseases. The proanthocyanidins found in plasma are very different from the original flavonoids in food sources. The use of physiologically appropriate conjugates of proanthocyanidins is essential for the in vitro analysis of flavonoid bioactivity. In this study, the effect of different proanthocyanidin-rich extracts, which were obtained from cocoa (CCX), French maritime pine bark (Pycnogenol extract, PYC) and grape seed (GSPE), on lipid homeostasis was evaluated. Hepatic human cells (HepG2 cells) were treated with 25 mg/L of CCX, PYC or GSPE. We also performed in vitro experiments to assess the effect on lipid synthesis that is induced by the bioactive GSPE proanthocyanidins using the physiological metabolites that are present in the serum of GSPE-administered rats. For this, Wistar rats were administered 1 g/kg of GSPE, and serum was collected after 2 h. The semipurified serum of GSPE-administered rats was fully characterized by liquid chromatography tandem triple quadrupole mass spectrometry (LC-QqQ/MS(2)). The lipids studied in the analyses were free cholesterol (FC), cholesterol ester (CE) and triglycerides (TG). All three proanthocyanidin-rich extracts induced a remarkable decrease in the de novo lipid synthesis in HepG2 cells. Moreover, GSPE rat serum metabolites reduced the total percentage of CE, FC and particularly TG; this reduction was significantly higher than that observed in the cells directly treated with GSPE. In conclusion, the bioactivity of the physiological metabolites that are present in the serum of rats after their ingestion of a proanthocyanidin-rich extract was demonstrated in Hep G2 cells.

    The relations of gene polymorphism at the apolipoprotein B locus and serum lipid profile in children was studied in 308 normal 7-11 year-old children, including 151 boys and 157 girls. Blood samples were collected for all subjects, and then the serum and blood clot were separated. Serum lipids, including TC, TG, LDL-C, HDL-C, apoB, apoA I and Lp(a) were detected. Genome DNA was extracted from blood clot, then apoB-Xba I gene polymorphism were tested by PCR-RFLP method. The results showed that the distribution of apoB-Xba I genotype in 308 children accorded with Hardy-Weiberg inheritance equilibrium law. The frequency of heterozygote(+/-) was 13.3%, allele(+) was 0.067. The frequency of allele(+) was closed to the internal and Japanese reports (0.033 and 0.04), but much less than the Caucasians (0.50). This showed a ethnic and population difference in the inheritance variation. The average LDL-C levels of the heterozygotes(+/-) were 2.17 mmol/L, no difference compared with homozygotes(-/-) (2.21 mmol/L, P > 0.05). There was also no difference for the genotype distribution between the hyperlipidemia group and control group, which may be the results of no enough sample size and the sample selection, and so on. On the other hand, in normal children, serum lipids controlled by many genes, the effect of a single gene might be small. More studies and analysis on the relationship between serum lipids and multiple genes in multisites should be the next step. PMID:12561593

    Full Text Available Aim: Relationship between serum lipid level in chronic obstructive lung disease (COLD and lung cancer was not well documented. In our study we planned to compare serum lipid levels (Total Cholesterol-TC, low density lipoprotein cholesterol-LDL-C, trigliseride-TGL, and high density lipoprotein cholesterol-HDL-C in these common diseases. Material and Method: We evaluated 100 patients and 50 control group retrospectively. We enrolled the lipid parameters before any medical treatment start. Student%u2019s t-test and one-way ANOVA test was used for comparison of the patient characteristics and mean cholesterol level. Results: TC levels were higher in COLD disease than lung cancer group but not statistically significant. TGL levels were higher in lung cancer group than COLD and control group but this was also not statistically significant. Mild-moderate degree COLD patients had lower HDL-C than severe COLD patients (p=0.02. But TC and TGL levels were lower in severe COLD pateints. Small cell lung sancer and non-small lung cancers had statistically significantly lower TC and TGL levels (respectively p=0.04 and p=0.02. Discussion: We estimated that lipid leves of at the beginning of COLD were decreased to provide lipid necessity in cancer tissue due to tumor rapid cell proliferation in cancer, tumor cachexia and increased nutrition problems when developed lung cancer. Larger prospective studies are required to more accurate assessment this issue.

    The changes in total serum cholestrol, serum triglyceride, HDL-cholesterol and LDL-cholesterol after twenty eight (28) days of consumption of moderate quantity of a commercial coffee preparation (NESCAFE brand) were studied in 30 human subjects consisting of 20 male and 10 female healthy adults. Significant increases in the mean total serum cholesterol concentration (110.8-126.5 mg/100 mls) and LDL- cholesterol concentration (78.4-94.5 mg/100 ml) were observed in the subjects. No significant differences were obtained in the mean HDL cholesterol concentration and in the mean serum triglyceride levels. The differences observed in the mean total serum cholesterol, LDL cholesterol, HDL- cholesterol and triglyceride concentrations in the individual male and female groups studied were not statistically significant. The results from this study suggest that short-term consumption of coffee may increase the total serum cholesterol and LDL cholesterol levels. It is therefore possible that long-term consumption of coffee may lead to clinically significant alterations in serum lipid profile and could be important in the aetiology of atherosclerotic vascular diseases such as coronary heart disease.

    Randall, Janis Avril

    Concentrations of chromium (Cr) in hair, serum, and urine, and serum concentrations of insulin and lipids of a selected group of men exposed to trivalent Cr (Cr III) were compared with those of men not exposed to Cr. Seventy -three tannery workers (TW) (mean age 37 +/- 12 years) from four Southern Ontario tanneries and fifty-two control subjects (CS) (mean age 41 +/- 13 years), matched for age, race, and socioeconomic status, from the Guelph and Toronto areas participated. The median hair and serum Cr concentrations for the TW were significantly higher (p leather tanning industry, is absorbed and retained. Absorption of Cr III had no significant effect on serum insulin concentrations or serum lipid profiles. These results also suggest that concentrations of Cr in hair, serum, and urine are valid biological indices of industrial exposure to Cr III.

    2013-07-01

    To elucidate the relationships between alexithymia, suicide ideation and serum lipid levels in drug-naïve adult outpatients with a DSM-IV diagnosis of Panic Disorder (PD), 72 patients were evaluated. Measures were the Panic Attack and Anticipatory Anxiety Scale, the Toronto Alexithymia Scale (TAS-20), the Scale of Suicide Ideation (SSI) and the Montgomery Åsberg Depression Rating Scale (MADRS). Alexithymic patients showed higher scores on all rating scales and altered serum lipid levels than non-alexithymics. In the hierarchical regression model, the presence of lower HDL-C and higher VLDL-C levels and Difficulty in Identifying Feelings dimension of TAS-20 were associated with higher suicide ideation. In conclusion, alexithymic individuals with PD may show a cholesterol dysregulation that may be linked to suicide ideation. The authors discuss study limitations and future research needs.

    2016-02-01

    Full Text Available BACKGROUND HIV patients receiving highly active Anti-Retroviral Therapy (HAART usually suffer from side effects like hepatitis, neurological problems, abnormal fat distribution etc. Among these, the most physical, mental and cosmetically disturbing side effect is adipose tissue alterations (ATA, also called as lipodystrophy, which is abnormal fat deposition (Lipohypertrophy and/or fat atrophy (Lipoatrophy. AIM Several studies have shown dyslipidemia in patients on HAART, but there are very few studies on the lipid profile changes in patients on ART with ATA. Hence a study was conducted to assess the serum lipid profile and transaminases activity in patients on ART with ATA and also to evaluate whether lipid profile parameters can predict ATA changes in HIV patients on HAART. METHOD Randomly selected HIV positive patients, who were attending ART centre, were included in the study. Twenty five of these patients in whom HAART was yet to be started were considered as Control group, 25 patients on HAART for more than 12 months but without ATA as ART group and 23 patients on HAART with ATA as ATA group. Lipid profile and serum transaminases in all the groups were assayed by standard methods. RESULTS Serum cholesterol and LDL were significantly increased in ART group and ATA group when compared to control group, but there was no significant difference in lipid profile parameters between ART group and ATA group. Serum AST and ALT levels were significantly increased (p<0.02 in ATA group when compared to ART group. Buffalo hump was seen only in females in our study. Lipoatrophy (facial and limbs and central obesity was seen in males. CONCLUSION There was no significant change in lipid profile parameters in ATA group when compared with ART group. Hence lipid profile parameters are not good predictors of ATA changes in HIV patients on HAART. Significant increase in transaminase levels suggests increased hepatotoxity in ATA patients due to HAART drugs. There

    Full Text Available Aluminum (Al3+ overload is frequently associated with lipid peroxidation and neurological disorders. Aluminum accumulation is also reported to be related to renal impairment, anemia and other clinical complications in hemodialysis patients. The aim of the present study was to determine the degree of lipid peroxidation, platelet aggregation and serum aluminum in patients receiving regular hemodialytic treatment. The level of plasma lipid peroxidation was evaluated on the basis of thiobarbituric acid reactive substances (TBARS. Mean platelet peroxidation in patients undergoing hemodialysis was significantly higher than in normal controls (2.7 ± 0.03 vs 1.8 ± 0.06 nmol/l, P<0.05. Platelet aggregation and serum aluminum levels were determined by a turbidimetric method and atomic absorption spectrophotometry, respectively. Serum aluminum was significantly higher in patients than in normal controls (44.5 ± 29 vs 10.8 ± 2.5 µg/l, P<0.05. Human blood platelets were stimulated with collagen (2.2 µg/ml, adenosine diphosphate (6 µM and epinephrine (6 µM and showed reduced function with the three agonists utilized. No correlation between aluminum levels and platelet aggregation or between aluminum and peroxidation was observed in hemodialyzed patients.

    Full Text Available Lipid abnormalities in hypothyroidism contribute to the disproportionate increase in cardiovascular risk. A possible relationship between serum level of magnesium (Mg and calcium (Ca and cardiovascular disease was recorded. In this work, the possible correlation between lipid profile components and serum cations Ca and Mg was investigated. Matched healthy women were evaluated in a cross-sectional study. All parameters were measured spectrophotometrically. The results showed a significant decrease (P < 0.05 in high-density lipoprotein-cholesterol (HDL-C, total and ionized Mg in hypothyroid patients in comparing with control group. There was a significant increase (P < 0.05 in serum total cholesterol (TC, low-density lipoprotein-cholesterol (LDL-C and (LDL-C/(HDL-C ratio in hypothyroid patients as compared with control group. However, no correlation was found between the cation levels and lipid profile of the studied groups. It can be concluded that patients with hypothyroidism exhibited elevated atherogenic parameters (TC and LDL-C and high risk of cardiovascular diseases.

    1. The aim of the present study was to examine the effects of moderate exercise on serum lipids, lipoproteins and apolipoproteins in seven sedentary young women under controlled conditions. 2. The subjects exercised on separate days for 30 or 60 min at an intensity of 60% of maximal oxygen uptake on a cycle ergometer. Total cholesterol, triglycerides, high-density lipoprotein-cholesterol (HDL-C), HDL2-C, HDL3-C, low-density lipoprotein-cholesterol, apolipoproteins A-I, A-II and B were measured in the serum at the end of the 60 min rest period before each exercise, immediately after the performance of each exercise and at 30 min and 1, 2 and 24 h after each exercise. 3. The results showed that there were no significant differences between the pre- and postexercise samples for any of the parameters tested. 4. The results of the present study suggest that a single bout of exercise designed to simulate a typical training workout has no noticeable effect on serum lipids, lipoproteins and apolipoproteins in normal sedentary young women who have normal lipid profiles, are in the follicular phase of their menstrual cycle and who consume a relatively low-fat diet.

    Full Text Available BACKGROUND: Changes in lipid metabolism occurs in normal pregnancy during third trimester. This dyslipidemia indicative of insulin resistance is accentuated with Pre - eclampsia and Eclampsia. It contributes to both the pathogenesis of pre - eclampsia and to the risk of later - life cardiovascular disease in these patients. I have attempted to study the alterations in lipid profile in normal pregnancy, pre - eclampsia and eclampsia. MATERIALS AND METHODS: This study was conducted in Govt . Medical College for a period of 6 months. 25 normotensive non - pregnant women, 25 normal pregnant women, 25 pre eclampsia patients and 25 eclampsia patients were selected All the antenatal were in third trimester. Serum lipid profile was determined. Data analysis was done by excel sheet and SPSS software. RESULTS : Serum Triglycerides, VLDL, Total Cholesterol, LDL Cholesterol and HDL Cholesterol were significantly elevated in last trimester of normal pregnancy when compared to normal non - pregnant women. Also a significant increase in serum triglycerides and VLDL were seen in pre - eclampsia when compared to that of normal pregnancy. Also a significant decrease in HDL Cholesterol levels were seen in eclampsia when compared to normal pregnancy. CONCLUSION : Dyslipidemia suggestive of an exaggerated insulin resistance was found in pre eclampsia and eclampsia. Early interventions like prevention of obesity, exercise and balanced diet can reduce the risk of future cardiovascular morbidity and mortality in these patients.

    Full Text Available Abstract Background Cardiovascular disease (CVD and colon cancer incidence are known to be closely related to dietary factors. This article evaluated effects of krill oil (KO on serum lipids of hyperlipidemia rats and human colon cancer cells (SW480. Serum lipids of rats fed with high fat diet (HFD and different doses of KO were measured by automatic analyzer. Effect of KO on viability of cells was determined by methyl thiazolyl tetrazolium (MTT assay. Results Except for higher dose group, body weights decreased significantly. Total cholesterol (TC, LDL-cholesterol (LDL-C of all dose groups, Triglycerides (TG of low and mid dose groups descended significantly, while there were no significant differences of HDL-cholesterol (HDL-C, compared with control group. Treatment of colon cancer cells with KO also resulted in time-dependent inhibition of cell growth. Conclusion Our findings indicated that the consumption of KO may provide benefits to control serum lipid levels in certain diseases and inhibit growth of colon cancer cells. Therefore, KO may be a good candidate for development as a functional food and nutraceutical.

    Both bisphenol A (BPA, an endocrine disrupting chemicals) and genistein (a phytoestrogen mainly derived from leguminosae) are able to bind to estrogen receptors, but they are considered to have different effects on metabolic syndrome, surprisingly. We here investigate the effects of an environmentally relevant dose of BPA alone and the combined effects with genistein on lipid metabolism in rats. Eight groups of adult male Wistar rats, fed with either standard chow diet or high-fat diet, were treated with BPA (50μg/kg/day), genistein (10mg/kg/day), and BPA plus genistein for 35 weeks, respectively. Metabolic parameters in serum and liver were determined; the hematoxylin/eosin and oil Red O staining were used to observe liver histologically; gene expressions related to hepatic lipid metabolism were analyzed by Real-time PCR; protein expressions of PPARγ, PPARα and LC3 in liver were analyzed by western blotting. No difference of body weight gain, total energy intake, liver weight/body weight or body fat percentage in both STD- and HFD-fed sub-groups was observed after treatment with BPA, genistein, or BPA plus genistein (P>0.05). Genistein alleviated lipid metabolism disorder and decreased the mRNA and protein expression of PPARγ (P0.05) or combined with genistein. Our findings suggest that long-term environmentally relevant dose of BPA did not affect lipid metabolism, and had no synergetic or antagonistic roles on genistein’s beneficial function on hepatic lipid metabolism.

    Cholesterol derivatives M1-M6 as synthetic cationic lipids were designed and the biological evaluation of the cationic liposomes based on them as non-viral gene delivery vectors were described. Plasmid pEGFP-N1, used as model gene, was transferred into 293T cells by cationic liposomes formed with M1-M6 and transfection efficiency and GFP expression were tested. Cationic liposomes prepared with cationic lipids M1-M6 exhibited good transfection activity, and the transfection activity was parallel (M2 and M4) or superior (M1 and M6) to that of DC-Chol derived from the same backbone. Among them, the transfection efficiency of cationic lipid M6 was parallel to that of the commercially available Lipofectamine2000. The optimal formulation of M1 and M6 were found to be at a mol ratio of 1:0.5 for cationic lipid/DOPE, and at a N/P charge mol ratio of 3:1 for liposome/DNA. Under optimized conditions, the efficiency of M1 and M6 is greater than that of all the tested commercial liposomes DC-Chol and Lipofectamine2000, even in the presence of serum. The results indicated that M1 and M6 exhibited low cytotoxicity, good serum compatibility and efficient transfection performance, having the potential of being excellent non-viral vectors for gene delivery.

    In this study we report a physical analysis of the membrane mechanics affecting the size of the highly curved region of a lipid nanotube (LNT) that is either connected between a lipid bilayer vesicle and the tip of a glass microinjection pipette (tube-only) or between a lipid bilayer vesicle and a vesicle that is attached to the tip of a glass microinjection pipette (two-vesicle). For the tube-only configuration (TOC), a micropipette is used to pull a LNT into the interior of a surface-immobilized vesicle, where the length of the tube L is determined by the distance of the micropipette to the vesicle wall. For the two-vesicle configuration (TVC), a small vesicle is inflated at the tip of the micropipette tip and the length of the tube L is in this case determined by the distance between the two interconnected vesicles. An electrochemical method monitoring diffusion of electroactive molecules through the nanotube has been used to determine the radius of the nanotube R as a function of nanotube length L for the two configurations. The data show that the LNT connected in the TVC constricts to a smaller radius in comparison to the tube-only mode and that tube radius shrinks at shorter tube lengths. To explain these electrochemical data, we developed a theoretical model taking into account the free energy of the membrane regions of the vesicles, the LNT and the high curvature junctions. In particular, this model allows us to estimate the surface tension coefficients from R( L) measurements.

    Temperature is the best known variable affecting the distribution of the archaeal glycerol dibiphytanyl glycerol tetraethers (GDGTs) in marine and freshwater systems. Other variables such as pH, ionic strength, or bicarbonate concentration may also affect archaeal GDGTs in terrestrial systems. Studies of pure cultures can help us pinpoint the specific effects these variables may have on archaeal lipid distribution in natural environments. In this study, three Sulfolobus species (HG4, HB5-2, HB9-6) isolated from Tengchong hot springs (pH 2-3, temperature 73-90°C) in China were used to investigate the effects of temperature, pH, substrate, and type of strain on the composition of GDGTs. Results showed that increase in temperature had negative effects on the relative contents of GDGT-0 (no cyclopentyl rings), GDGT-1 (one cyclopentyl ring), GDGT-2 and GDGT-3 but positive effects on GDGT-4, GDGT-4', GDGT-5 and GDGT-5'. Increase in pH, on the other hand, had negative effects on GDGT-0, GDGT-1, GDGT-4', GDGT-5 and GDGT-5', and positive effects on GDGT-3 and GDGT-4. GDGT-2 remained relatively constant with changing pH. When the HG4 was grown on different substrates, GDGT-5 was five time more abundant in sucrose-grown cultures than in yeast extract- or sulfur- grown cultures, suggesting that carbohydrates may stimulate the production of GDGT-5. For all three species, the ring index (average number of rings) of GDGTs correlated positively with incubation temperature. In HG4, ring index was much lower at optimal pH (3.5) than at other pH values. Ring index of HB5-2 or HB9-6 is higher than that of HG4, suggesting that speciation may affect the degree of cyclization of GDGT of the Sulfolobus. These results indicate that individual archaeal lipids respond differently to changes in environmental variables, which may be also species specific.

    Full Text Available Background & aim: The decrease of serum glucose level and lipids in diabetic patients is clinically significant. The purpose of this study was to determine the effect of Commiphora mukul extract on blood sugar and lipid profile in diabetic rats. Methods: In the present experimental study, thirty-two male Wistar rats were randomly divided into four groups: control, control treated with the extract, diabetic and diabetic treated with the extract. Diabetes was induced by intraperitoneal injection of Streptozotocin. In an eight week period, the control group of normal saline and the control group and diabetic recipient extract of CM oleo gum blue resin was given by gavage. Treatment resumed eight weeks with onset of hyperglycemia. The control and diabetic control groups received normal saline orally. Extract treated control and extract treated diabetic groups received extract of Commiphora mukul gum (300 mg/kg P.O. daily by gavage. At the end of this period, blood samples were collected from each rat and biochemical tests for investigation of glucose level and lipid profile was performed. One- way analysis of variance (ANOVA statistical test and Post-hoc test Tukey’s were used for data analysis Results: The study indicated that diabetes increases the serum levels of glucose, cholesterol, triglycerides, LDL and HDL. Administration of Commiphora mukul gum extract in diabetic groups significantly decreased the serum level of glucose, cholesterol(p<0.01 and triglyceride and LDL(p<0.001 and increased HDL(p<0.01. Conclusion: Commiphora mukul gum extract may well improve undesirable effects of diabetes on serum level of glucose, cholesterol, triglyceride, LDL and HDL.

    Full Text Available Accumulating evidence indicates that the intestinal microbiota regulates our physiology and metabolism. Bacteria marketed as probiotics confer health benefits that may arise from their ability to affect the microbiota. Here high-throughput screening of the intestinal microbiota was carried out and integrated with serum lipidomic profiling data to study the impact of probiotic intervention on the intestinal ecosystem, and to explore the associations between the intestinal bacteria and serum lipids. We performed a comprehensive intestinal microbiota analysis using a phylogenetic microarray before and after Lactobacillus rhamnosus GG intervention. While a specific increase in the L. rhamnosus-related bacteria was observed during the intervention, no other changes in the composition or stability of the microbiota were detected. After the intervention, lactobacilli returned to their initial levels. As previously reported, also the serum lipid profiles remained unaltered during the intervention. Based on a high-resolution microbiota analysis, intake of L. rhamnosus GG did not modify the composition of the intestinal ecosystem in healthy adults, indicating that probiotics confer their health effects by other mechanisms. The most prevailing association between the gut microbiota and lipid profiles was a strong positive correlation between uncultured phylotypes of Ruminococcus gnavus-group and polyunsaturated serum triglycerides of dietary origin. Moreover, a positive correlation was detected between serum cholesterol and Collinsella (Coriobacteriaceae. These associations identified with the spectrometric lipidome profiling were corroborated by enzymatically determined cholesterol and triglyceride levels. Actinomycetaceae correlated negatively with triglycerides of highly unsaturated fatty acids while a set of Proteobacteria showed negative correlation with ether phosphatidylcholines. Our results suggest that several members of the Firmicutes

    Full Text Available Abstract Background The breakdown of the blood-brain-barrier vascular endothelium is critical for entry of immune cells into the MS brain. Vascular co-morbidities are associated with increased risk of progression. Dyslipidemia, elevated LDL and reduced HDL may increase progression by activating inflammatory processes at the vascular endothelium. Objective To assess the associations of serum lipid profile variables (triglycerides, high and low density lipoproteins (HDL, LDL and total cholesterol with disability and MRI measures in multiple sclerosis (MS. Methods This study included 492 MS patients (age: 47.1 ± 10.8 years; disease duration: 12.8 ± 10.1 years with baseline and follow-up Expanded Disability Status Score (EDSS assessments after a mean period of 2.2 ± 1.0 years. The associations of baseline lipid profile variables with disability changes were assessed. Quantitative MRI findings at baseline were available for 210 patients. Results EDSS worsening was associated with higher baseline LDL (p = 0.006 and total cholesterol (p = 0.001, 0.008 levels, with trends for higher triglyceride (p = 0.025; HDL was not associated. A similar pattern was found for MSSS worsening. Higher HDL levels (p p = 0.033. Conclusions Serum lipid profile has modest effects on disease progression in MS. Worsening disability is associated with higher levels of LDL, total cholesterol and triglycerides. Higher HDL is associated with lower levels of acute inflammatory activity.

    Full Text Available Context: Low testosterone levels are associated with an atherogenic lipid profile and may contribute to the pathogenesis of atherosclerosis. Aims: Our study aimed to investigate the relationship between serum total testosterone (TT levels and lipid profile in angiographically confirmed coronary artery disease (CAD in men. Settings and Design: This is a case-control hospital-based study at Teaching Hospital, Karapitiya, Galle, Sri Lanka. Materials and Methods: Two hundred and six men, 103 with angiographically proven CAD and 103 healthy men as a control group were studied. The serum levels of TT and lipids were assessed. Statistical Analysis: Data were analyzed using Minitab software (version 15 for Windows. Results: The mean concentrations of lipid parameters of patients and controls were as follows: Serum total cholesterol (TCh, 5.9 ± 2.8 vs. 5.2 ± 1.6 mmol/l (P = 0.022, low-density lipoprotein cholesterol (LDL-Ch, 3.9 ± 1.2 vs. 3.1 ± 0.5 mmol/l (P = 0.001, high-density lipoprotein cholesterol (HDL-Ch, 1.1 ± 0.5 vs. 1.4 ± 0.6 mmol/l (P = 0.001, and TGs, 2.0 ± 1.0 vs. 1.5 ± 0.8 mmol/l (P = 0.001; lipid levels were significantly different between the two groups. The mean levels of TT in the patients and controls were 11.4 ± 2.7 vs. 18.1 ± 7.2 nmol/l (P = 0.001, significantly different. Among CAD patients, a significant positive association was found between testosterone and HDL-Ch (r = 0.623, P = 0.001, whereas a negative association was found with LDL-Ch (r = -0.579, P = 0.001. Conclusions: Low levels of TT in men with CAD that appear together with an atherogenic lipid milieu may be involved in the pathogenesis of CAD. The observed association between testosterone and HDL-Ch suggests a protective effect of the hormone.

    Full Text Available Abstract Objective Cigarette smoking had been confirmed as an increased risk for dyslipidemia, but none of the evidence was from long-lived population. In present study, we detected relationship between cigarette smoking habits and serum lipid/lipoprotein (serum Triglyceride (TG, Total cholesterol (TC, Low-density lipoprotein (LDL and high-density lipoprotein (HDL among Chinese Nonagenarians/Centenarian. Methods The present study analyzed data from the survey that was conducted on all residents aged 90 years or more in a district, there were 2,311,709 inhabitants in 2005. Unpaired Student’s t test, χ2 test, and multiple logistic regression were used to analyze datas. Results The individuals included in the statistical analysis were 216 men and 445 women. Current smokers had lower level of TC (4.05 ± 0.81 vs. 4.21 ± 0.87, t = 2.403, P = 0.017 and lower prevalence of hypercholesteremia (9.62% vs. 15.13%, χ2 = 3.018,P = 0.049 than nonsmokers. Unadjusted and adjusted multiple logistic regressions showed that cigarette smoking was not associated with risk for abnormal serum lipid/lipoprotein. Conclusions In summary, we found that among Chinese nonagenarians/centenarians, cigarette smoking habits were not associated with increased risk for dyslipidemia, which was different from the association of smoking habits with dyslipidemia in general population.

    2011-07-01

    Full Text Available Background: Diabetic retinopathy is the commonest and usually the first observable vascular complication of diabetes mellitus. Along with hyperglycaemia, dyslipidaemia is a contributing factor for the occurrence of diabetic retinopathy. It is postulated that dyslipidaemia results in formation of hard exudate by increasing blood viscosity and altering the fibrinolytic system. A case control study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka during the period of January 2006 to December 2007 to evaluate the serum lipid profile in newly diagnosed type 2 diabetic subjects with diabetic retinopathy. Materials and Methods: Total 85 newly diagnosed type 2 diabetic subjects were included in this study, 40 were cases having retinopathy and 45 were age and sex matched controls without retinopathy. Serum triglyceride (TG, total cholesterol (TC, low density lipoprotein cholesterol (LDL-C and high density lipoprotein cholesterol (HDL-C were compared between cases and controls. Unpaired t-test and chi-square test were done between groups as tests of significance. Results: All the parameters of lipid profile showed dyslipidaemic trend both in cases and controls. In the cases TG was significantly higher and HDL-C was significantly lower than that of controls (p < 0.05 whereas no significant difference was found between cases and controls with respect to serum TC and LDL-C. Conclusion: It can be concluded that high TG and low HDL-C are associated with diabetic retinopathy in newly diagnosed type 2 diabetes.

    Objective: Lipids and steroid hormones are closely linked. While cholesterol is the substrate for (placental) steroid hormone synthesis, steroid hormones regulate hepatic lipid production. The aim of this study was to quantify circulating steroid hormones and lipid metabolites, and to characterize their interactions in normal and pathological pregnancies with a focus on hepatic and placental pathologies. Methods: A total of 216 serum samples were analyzed. Group A consisted of 32 patients with uncomplicated pregnancies who were analyzed at three different time-points in pregnancy (from the first through the third trimester) and once post partum. Group B consisted of 36 patients (24th to 42nd week of gestation) with pregnancy pathologies (IUGR n = 10, preeclampsia n = 13, HELLP n = 6, intrahepatic cholestasis n = 7) and 31 controls with uncomplicated pregnancies. Steroid profiles including estradiol, progesterone, and dehydroepiandrosterone were measured by GC-MS and compared with lipid concentrations. Results: In Group A, cholesterol and triglycerides correlated positively with estradiol (cholesterol ρ = 0.50, triglycerides ρ = 0.57) and progesterone (ρ = 0.49, ρ = 0.53) and negatively with dehydroepiandrosterone (ρ = − 0.47, ρ = − 0.38). Smoking during pregnancy affected estradiol concentrations, leading to lower levels in the third trimester compared to non-smoking patients (p < 0.05). In Group B, cholesterol levels were found to be lower in IUGR pregnancies and in patients with HELLP syndrome compared to controls (p < 0.05). Steroid hormone concentrations of estradiol (p < 0.05) and progesterone (p < 0.01) were lower in pregnancies with IUGR. Discussion: Lipid and steroid levels were affected most in IUGR pregnancies, while only minor changes in concentrations were observed for other pregnancy-related disorders. Each of the analyzed entities displayed specific changes. However, since the

    Objective: To assess the effect of quercetin (flavonoid) against lindane induced alterations in lipid profile of wistar rats. Methods: Rats were administered orally with lindane (100 mg/kg body weight) and quercetin (10 mg/kg body weight) for 30 days. After the end of treatment period lipid profile was estimated in serum and tissue. Results: Elevated levels of serum cholesterol, triglycerides, low density lipoprotein (LDL), very Low Density Lipoprotein (VLDL) and tissue triglycerides, cholesterol with concomitant decrease in serum HDL and tissue phospholipids were decreased in lindane treated rats were found to be significantly decreased in the quercetin and lindane co-treated rats. Conclusions: Our study suggests that quercetin has hypolipidemic effect and offers protection against lindane induced toxicity in liver by restoring the altered levels of lipids. The quercetin cotreatment along with lindane for 30 days reversed these biochemical alterations in lipids induced by lindane.

    Background Although many factors are involved in the etiology of xanthelasma palpebrum, lipid disorder is strongly associated with its induction. Xanthelasma palpebrum, the most common type of xanthoma, usually presents in middle-aged females and results in aesthetic problems. Objective To evaluate thelipid profile and important clinical aspects of xanthelasma palpebrum patients. Methods In this descriptive study, we enrolled 42xanthelasma palpebrumpatients, and 42 cases of non-inflammatory skin disorders as thecontrol group, matched for age and gender.The clinical characteristics of the patients and fasting serum lipid profile were recorded for both groups. The data obtained were analyzed using SPSS-16. Results Xanthelasma palpebrum was found more commonly in middle-aged females with disease onset of less than 1 year, and without significant familial history of xanthoma. Furthermore,xanthelasma lesionswere most often seen in the upper lid with mild extension and was rarely associated with systemic disease. There was no statistically significant difference between two groups regarding hypertriglyceridemia (p= 0.231) and hypercholesterolemia (p= 0.302). The mean serum levels of cholesterol (221.51±60.4 mg/dl), triglyceride (185.98±71.1 mg/dl) and VLDL (37.7±17.6 mg/dl) were significantly higher and themedian HDL (36.2 (31, 41) mg/dl) level was lower in thepatient group. Conclusion In our study, hypercholesterolemia and hypertriglyceridemia did not reveal a significant difference between thepatient and control groups; however, mean serum values for cholesterol, triglyceride, VLDL and HDL showed a significant difference between the two groups. Therefore, in addition to lipid abnormality, other factors could be involved in the pathogenesis of xanthelasma palpebrum. PMID:27579742

    Soya proteins and isoflavones have been reported to exert beneficial effects on the serum lipid profile. More recently, this claim is being challenged. The objective of this study was to comprehensively examine the effects of soya consumption on the lipid profile using published trials. A detailed literature search was conducted via MEDLINE (from 2004 through February 2014), CENTRAL (The Cochrane Controlled Clinical Trials Register) and ClinicalTrials.gov for randomised controlled trials assessing the effects of soya on the lipid profile. The primary effect measure was the difference in means of the final measurements between the intervention and control groups. In all, thirty-five studies (fifty comparisons) were included in our analyses. Treatment duration ranged from 4 weeks to 1 year. Intake of soya products resulted in a significant reduction in serum LDL-cholesterol concentration, -4.83 (95% CI -7.34, -2.31) mg/dl, TAG, -4.92 (95% CI -7.79, -2.04) mg/dl, and total cholesterol (TC) concentrations, -5.33 (95% CI -8.35, -2.30) mg/dl. There was also a significant increase in serum HDL-cholesterol concentration, 1.40 (95% CI 0.58, 2.23) mg/dl. The I² statistic ranged from 92 to 99%, indicating significant heterogeneity. LDL reductions were more marked in hypercholesterolaemic patients, -7.47 (95% CI -11.79, -3.16) mg/dl, than in healthy subjects, -2.96 (95% CI -5.28, -0.65) mg/dl. LDL reduction was stronger when whole soya products (soya milk, soyabeans and nuts) were used as the test regimen, -11.06 (95% CI -15.74, -6.37) mg/dl, as opposed to when 'processed' soya extracts, -3.17 (95% CI -5.75, -0.58) mg/dl, were used. These data are consistent with the beneficial effects of soya proteins on serum LDL, HDL, TAG and TC concentrations. The effect was stronger in hypercholesterolaemic subjects. Whole soya foods appeared to be more beneficial than soya supplementation, whereas isoflavone supplementation had no effects on the lipid profile.

    The physical interaction between a lipid vesicle and a silver nanoparticle (AgNP)-human serum albumin (HSA) protein "corona" has been examined. Specifically, the binding of AgNPs and HSA was analyzed by spectrophotometry, and the induced conformational changes of the HSA were inferred from circular dichroism spectroscopy. The fluidity of the vesicle, a model system for mimicking cell membrane, was found to increase with the increased exposure to AgNP-HSA corona, though less pronounced compared to that induced by AgNPs alone. This study offers additional information for understanding the role of physical forces in nanoparticle-cell interaction and has implications for nanomedicine and nanotoxicology.

    Full Text Available The association between pre - eclampsia and atherosclerosis is a much discussed topic. The changes in lipid profile observed during pregnancy have significant effects on woman’s long term health, because elevated serum triglycerides is an independent risk factor for coronar y artery disease. The aim of this study is to assess the lipid profile in pregnancy with pre - eclampsia and to compare that with normal pregnancy. METHOD: The study group consisted of 150 subjects in three groups of 50 each, selected according to the inclusion criteria. The groups were normotensive pregnant women, those with mild pre - eclampsia and severe pre - eclampsia. Blood samples were collected from all the subjects after 12hours of fasting, which was centrifuged at 3000rpm for 10 minutes and analyz ed for serum cholesterol, serum triglycerides, serum HDL, LDL and VLDL using an automatic analyzer. Data was analyzed using Chi square test and ANOVA using SPSS software version 16.0. A p value of <0.05 was considered significant. STUDY DESIGN: Cross secti onal study . STUDY SETTING: Department of Obstetrics and Gynaecology, Govt. Medical College, Kozhikode, Kerala, India. RESULTS : In this study, 48.7% of the subjects were in the age group of 18 - 25 years and 17.3%, above 30 years. The total cholesterol level was high in 54.7% of the entire subjects. The highest distribution were in the severe pre - eclampsia group with a significant p value of <0.001. The triglyceride values were high in 18% of normotensive subjects, while it was 46% and 80% in the mild and seve re pre - eclampsia groups respectively. HDL values were normal in the entire normotensive group. In the mild and severe pre - eclampsia groups, 96% and 86% had normal HDL values. High LDL values were seen in 8% of normotensive group, but it was 32% and 28% in the mild and severe pre - eclampsia group respectively, with a significant p value of <0.001. VLDL level was high in 18% of the normotensive group, while

    Objective:To analyze changes of serum lipid and hs-CRP levels in patients with subclinical hypothyroidism in order to explore their correlations with TSH level.Methods:A total of 90 patients with subclinical hypothyroidism were included in the study and divided into the mild, moderate, and severe groups according to TSH level with 30 cases in each group; meanwhile, 30 healthy individuals were served as the control groups. The changes of the levels of TSH, serum lipid indicators (TC, TG, HDL-C, LDL-C, ApoA, ApoB, and Lpa), and hs-CRP in the four groups were observed. The correlation of serum lipid and hs-CRP with TSH was analyzed. Results: The levels of TSH, TC, TG, Lpa, and hs-CRP in the subclinical hypothyroidism subgroups were significantly higher than those in the control group. The levels of HDL-C, LDL-C, ApoA, and ApoB in patients with subclinical hypothyroidism were increased when compared with the control group. The levels of HDL-C, LDL-C, and ApoB in the moderate and severe groups were significantly higher than those in the control group. ApoA level in the severe group was significantly higher than that in the control group. LDL-C in the moderate group was significantly higher than that in the mild group, and that in the severe group was significantly higher than that in the moderate group. ApoB level in the severe group was significantly higher than that in the mild group. Spearman correlation analysis showed that TC, TG, LDL-C, ApoB, Lpa, and hs-CRP were positively correlated with TSH level, while HDL-C and ApoA had no correlation with TSH level.Conclusions:The levels of serum lipid and hs-CRP are abnormally elevated in patients with subclinical hypothyroidism, and are gradually increased along with the disease progression, which is closely associated with TSH level.

    Dietary therapy is the cornerstone of lipid management in patients with type 2 diabetes mellitus. The key strategies are the reduction of intake of saturated fat, trans unsaturated fat and cholesterol, and the reduction of energy intake to promote weight loss. This approach will produce significant improvements in the serum levels of low-density lipoprotein (LDL) cholesterol, triglycerides, and high-density lipoprotein (HDL) cholesterol. According to both the American Diabetes Association and the National Cholesterol Education Program (NCEP), the primary target of therapy is the serum LDL cholesterol level, with the secondary targets being non-HDL cholesterol, triglycerides, and HDL cholesterol. The recently updated guidelines of the NCEP place new emphasis on increasing soluble fiber intake to 10 to 25 g/d and adding foods fortified with plant stanols/sterols (2 g/d) as options to enhance the LDL cholesterol-lowering effect of diet.

    Three cationic lipids with lysylated(l), histidylated(2), and arginylated(3) headgroups and cholesterol hy-drophobic moiety were synthesized. The average sizes of liposomes and lipoplexes were around 100 and 160 nm, re-spectively. The gene transfection efficiency of the three lipoplexes loaded with pGL3 or pORF-LacZ was compared on 293T cells in the presence or the absence of serum. The transfection efficiency of the three lipoplexes in a se-rum-free medium was 2 to 3-fold higher than that of dioleoyl-trimethylammonium propane(DOTAP). In the presence of serum, however, most of the lipoplexes showed lower transfection activities; only lipoplex 3 retained its high transfection efficiency.

    Full Text Available Berries have shown several cardiovascular health benefits and have been associated with antioxidant functions in experimental models. Clinical studies are limited. We examined the antioxidant effects of freeze-dried strawberries (FDS in adults [n=60; age: 49±10 years; BMI: 36±5 kg/m2 (mean ± SD] with abdominal adiposity and elevated serum lipids. Participants were randomized to one of the following arms: low dose strawberry (25 g/day FDS, low dose control beverage (LD-C, high dose strawberry (50 g/d FDS, and high dose control beverage (HD-C for 12 weeks. Control beverages were matched for calories and total fiber. Plasma antioxidant capacity, trace elements (copper, iron, selenium, and zinc, whole blood glutathione (GSH, and enzyme activity (catalase, glutathione peroxidase, and glutathione reductase were examined at screening (0 week and after 12 weeks’ intervention. At 12 weeks, plasma antioxidant capacity and glutathione levels were higher in the strawberry versus control groups (low and high dose FDS: 45% and 42% for plasma antioxidant capacity and 28% and 36% for glutathione, resp.; glutathione was higher in the high versus low dose strawberry group (all p<0.05. Serum catalase activity was higher in the low dose strawberry (43% versus control group (p<0.01. No differences were noted in plasma trace elements and glutathione enzyme activity. Dietary strawberries may selectively increase plasma antioxidant biomarkers in obese adults with elevated lipids.

    Full Text Available Evidence of the role of ANGPTL3, a liver-secreted glycoprotein, in serum lipid turnover, led us to hypothesize that this protein may be involved in modification of the lipid profile induced by exercise-training. Given the lack of data regarding this issue, the main goal of the present study was to investigate the effects of regular participation in a recreational physical activity program on serum ANGPTL3 and selected lipid profile measures in young, apparently healthy female and male adults. We compared serum ANGPTL3, lipid profile measures, common lipid ratios, the Atherogenic Index of Plasma (AIP and glucose in fasting blood samples derived from 22 active physical education students including active females (AF, N=6 and males (AM, N=16 with samples from 28 relatively sedentary agematched peers, including female (SF, N=9 and male (SM, N=19 individuals not involved in any regular physical conditioning program. Despite high inter-individual variability of serum ANGPTL3, there was a general tendency toward higher serum ANGPTL3 and HDL-C in women compared to men, but without significant differences related to their physical activity status. Based on both routine lipid profile measures and lipid ratios, all participants had normal lipid profiles, normal glycemia, as well as favorable anthropometric indices not suggesting increased cardiometabolic risk. However, lower levels of the TG/HDL-C ratio and AIP in physically active compared to relatively sedentary participants, reflecting the predominance of large, buoyant LDL particles, strongly support the view of beneficial healthpromoting effects of regular participation in recreational sport activities.

    The purpose of this study was to confirm and extend previous findings that serum cholesterol response to a fat-modified diet is enhanced by oat fiber. Participants (n = 236) were recruited from the Continental Illinois National Bank in Chicago. Data including weight, serum lipid level, lipoproteins, and 3-day food records were collected at baseline and every 4 weeks for 12 weeks. All participants were instructed to follow the fat-modified (Phase II) diet recommended by the American Heart Association (AHA). After 4 weeks, participants were randomly assigned to one of two groups. While both groups continued to follow the AHA diet, Group 1 was instructed to include 2 oz (56 g, dry wt) of oatmeal, isocalorically substituted for other carbohydrate foods. Group 2 served as the control and consumed no oat products throughout the study. Serum cholesterol values at baseline and after 4 weeks of the AHA diet were similar for both groups (203.9 and 193.0 mg/dl for Group 1 and 205.3 and 194.5 mg/dl for Group 2). After 4 weeks of oatmeal intervention, mean group differences were -6.8 and -2.1 mg/dl (P = 0.008 one-tailed t test) for Groups 1 and 2, respectively. Following an additional 4 weeks of oatmeal intervention, the Group 1 mean cholesterol increased slightly (0.9 mg/dl), while the Group 2 level decreased slightly (-0.7 mg/dl). Overall serum cholesterol responses for the two groups from Visit 2 to Visit 4 were -6.0 and -2.8 mg/dl for Groups 1 and 2, respectively (P = 0.074, one tail). Changes in weight were small and nonsignificant. Subgroup analyses revealed greater reductions in serum cholesterol among participants with the highest baseline serum cholesterol (-8.0 mg/dl vs -1.7 mg/dl for Subgroups 1 and 2, respectively). These data support previous findings that inclusion of oatmeal in a fat-modified diet is helpful in lowering serum cholesterol, particularly for individuals with elevated serum cholesterol levels.

    Objective:To explore the correlation of serum lipid metabolism and central retinal artery (CRA) hemodynamics with diabetic retinopathy (DR).Methods:A total of 120 patients with type 2 diabetes who were admitted in our hospital from May, 2015 to May, 2016 were included in the study and divided into NDR group (non-diabetic retinopathy), NPR group (non-proliferative retinopathy), and PR group (proliferative retinopathy) with 40 cases in each group according to DR clinical staging. Moreover, 50 healthy individuals who came for physical examinations were served as the control group. The full automatic biochemical analyzer was used to detect the levels of TG, TC, LDL-C, and HDL-C. The color Doppler flow imaging (CDFI) was used to detect EDV, PSV, RI, and PI of CRA and OA.Results:The levels of TG, TC, and LDL-C in NDG, NPR, and PR groups were gradually increased with the aggravation of retinopathy, HDL-C was reduced, the comparison among the three groups was statistically significant, and the comparison with the control group was statistically significant. EDV, PSV, and PI of CRA and OA in NDG, NPR, and PR groups were gradually increased with the aggravation of retinopathy, RI was reduced, the comparison among the three groups was statistically significant, and the comparison with the control group was statistically significant. Conclusions: The lipid metabolism disorder can promote the occurrence and development of DR. The change of CRA and OA hemodynamics is an important pathological basis for developing DR. Clinical detection of serum lipid level and monitoring of the changes of fundus artery hemocynamic parameters are of great significance in early detecting DR.

    Full Text Available Background: Pre-eclampsia is a common syndrome that occurs in the second half of pregnancy and often manifest with hypertension and significant proteinuria. It occurs in up to 10% of pregnancies and is the second cause of maternal mortality worldwide accounting for 17% of maternal deaths in Nigeria. Aim: This study was performed to compare the serum lipid levels of pregnant normotensive and pre-eclamptic women. Methods: It was a case control study involving 50 normotensive and 50 pre-eclamptic women at the University College Hospital, Ibadan, making a total of 100 participants. Their venous blood (5mls was collected after an overnight fast of 8-12 hours and this was analysed for cholesterol, triglyceride, high density lipoprotein-cholesterol (HDL-C, very low density lipoprotein-cholesterol (VLDL-C and low density lipoprotein-cholesterol (LDL-C using standard enzymatic methods. Results: The study showed that there was a significantly higher levels of triglyceride, VLDL-C and HDL-C in the pre-eclamptic compared to the normotensive group (P<0.05. Also on Spearman´s Correlation, there was a significant positive correlation between these lipids and pre-eclampsia. Conclusion: Lipids therefore have an important role in the aetiopathogenesis of pre-eclampsia and could be estimated during the conservative management of patients with pre-eclampsia.

    Haibo Ni

    Full Text Available Epidemiologic studies exploring causal associations between serum lipids and breast cancer risk have reported contradictory results. We conducted a meta-analysis of prospective cohort studies to evaluate these associations.Relevant studies were identified by searching PubMed and EMBASE through April 2015. We included prospective cohort studies that reported relative risk (RR estimates with 95% confidence intervals (CIs for the associations of specific lipid components (i.e., total cholesterol [TC], high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], and triglycerides [TG] with breast cancer risk. Either a fixed- or a random-effects model was used to calculate pooled RRs.Fifteen prospective cohort studies involving 1,189,635 participants and 23,369 breast cancer cases were included in the meta-analysis. The pooled RRs of breast cancer for the highest versus lowest categories were 0.96 (95% CI: 0.86-1.07 for TC, 0.92 (95% CI: 0.73-1.16 for HDL-C, 0.90 (95% CI: 0.77-1.06 for LDL-C, and 0.93 (95% CI: 0.86-1.00 for TG. Notably, for HDL-C, a significant reduction of breast cancer risk was observed among postmenopausal women (RR = 0.77, 95% CI: 0.64-0.93 but not among premenopausal women. Similar trends of the associations were observed in the dose-response analysis.Our findings suggest that serum levels of TG but not TC and LDL-C may be inversely associated with breast cancer risk. Serum HDL-C may also protect against breast carcinogenesis among postmenopausal women.

  8. Assessment of serum lipids in patients with age related macular degeneration from Pakistan

    International Nuclear Information System (INIS)

    Objective: To determine serum lipids in patients with age related macular degeneration from Pakistani population. Methods: The study was a cross sectional, randomized and case-control. Selected subjects ages were >50 years and were normotensive, non-diabetic with no family history of any such disease and no complication of posterior ocular chamber other than age related macular degeneration (AMD). Controls were age matched healthy individuals with no symptoms of AMD. Diagnosis of AMD was done through conventional diagnostic techniques by professional ophthalmologists. Serum samples were analyzed for total cholesterol, triglycerides, LDL and HDL using commercially available kits. Data were compared with Student's t-test. Pearson correlation was calculated for relationship between different parameters. P<0.05 was considered significant. Results: Compared to controls, AMD patients had significantly greater total cholesterol concentration (p<0.041), and power HDL/LDL ratio (p<0.038), while serum triglycerides, HDL and LDL were non-significantly different from control subjects. Total cholesterol in AMD patients was significantly correlated with TG, LDL and HDL (p<0.0001). Conclusion: The study indicates that high cholesterol might be a predictor of AMD and can be a diagnostic parameter. (author)

    Full Text Available Abstract Background The mortality rate of colorectal cancer ranks third behind lung and hepatic cancer in Taiwan. Colorectal cancer mostly arises from adenomatous polyps of left colon. The aim of our study was to examine the association of serum lipids with the histological pattern of rectosigmoid adenoma. Methods There were 2,506 eligible examinees aged 20 and above who underwent sigmoidoscopy as a screening examination in National Cheng Kung University Hospital between January 2003 and October 2006. They were classified into three groups: tubular adenoma (333 subjects, villous-rich (tubulovillous/villous adenoma (53 subjects and normal (2,120 subjects. We defined high total cholesterol (TC as a level ≧200 mg/dl, low high-density lipoprotein cholesterol (HDL-C as a level Results Among the study population, 333 subjects (13.3% had tubular adenomas and 53 subjects (2.1% had villous-rich adenomas. The odds ratio (OR for villous-rich adenoma in subjects with TG≧200 mg/dL compared to those with TG Conclusions Our study showed that subjects with high serum TG tended to have a higher risk of tubulovillous/villous adenoma in rectosigmoid colon. Therefore, reducing the serum TG level might be one method to prevent the incidence of colorectal cancer.

    The newly-generated lipid mediators include products of arachidonate metabolism, prostaglandins and leukotrienes. In this study, serum lipids and fatty acids, including arachidonic acid (C20:4) were examined in 12 normal subjects (6 males and 6 females) and 23 subjects with chronic urticaria (6 males and 17 females), including 17 who made an excellent or good recovery (4 males and 13 females). The results indicated a relationship between chronic urticaria and serum lipids and fatty acids. The omega 6 (n-6) and omega 3 (n-3) series of polyunsaturated fatty acids and lipid peroxidation were suggested that may be one of the mediators in chronic urticaria. Pantethine, glutathione and ascorbic acid were effective in controlling chronic urticaria. PMID:2794222

    Full Text Available Background: Alcoholic cirrhosis is often associated with impaired lipid metabolism. However, there are only a few studies regarding lipid profile in alcoholic cirrhosis that have been undertaken in India. The aim of the study is to assess the degree of alteration of serum lipid profile in alcoholic cirrhotic patients and also to detect its relationship with the age of the patients and the alcohol consumption pattern. Patients and Methods: This cross-sectional study was conducted in a teaching hospital of north-eastern India for 1 year with 100 patients with alcoholic cirrhosis (cases and 50 healthy individuals (controls without history of alcohol consumption. A questionnaire of personal characteristics including history of alcoholism was completed for each patient. Serum lipid profile (total, low-density lipoprotein (LDL, high-density lipoprotein (HDL cholesterol and triglyceride was recorded for each case and control. t test of significance was applied for statistical analysis. Results: Majority of the cases were in the 41-50 years age group. There was no relationship of cirrhosis with the type of alcoholic beverage, but a definite relationship was observed with the quantity and the duration of alcohol consumption. In patients with cirrhosis, the total serum cholesterol level was decreased. There was a significant decrease in serum HDL and LDL cholesterol compared with the control group ( P < 0.001. However, the serum triglyceride levels were significantly increased in alcoholic cirrhotic patients compared with the control group ( P < 0.001. Conclusion: In this study, we found that there was marked alteration of serum lipid profile values in patients with alcoholic cirrhosis compared with normal, non-cirrhotic individuals. Therefore, a search for lipid profile abnormality should be performed in every cirrhotic patient.

    Full Text Available Introduction. Serbia is the country with extremely low birth rate and a relatively high percentage of preterm deliveries (8%. With this in mind, discovering new diagnostic methods that could be used for the prediction of preterm delivery is of great importance. In this study we tried to determine whether bacterial vaginosis and chlamydial infection could provoke preterm delivery by activation of systemic cytokine network. Objective. The aim of this study was to determine serum levels of proinflammatory cytokines (IL-1β, IL-8, IFN-γ, IL-6 and TNF-α in pregnant women with symptoms of preterm delivery and to make correlation between these parameters and the presence of bacterial vaginosis or chlamydial infection. Method. In the serum of 35 pregnant women, which were divided in groups according to the presence or absence of bacterial vaginosis and chlamydial infection, commercial ELISA tests for proinflammatory cytokines were performed. Results. The serum level of IFN-γ was significantly increased in pregnant women having chlamydial infection, as well as the level of IL-1β in women with bacterial vaginosis. The levels of TNF-α, IL-6 and IL-8 were not significantly different between the investigated groups. Conclusion. The preliminary results obtained in this research point out the possibility that not only intrauterine or systemic infections, but also bacterial vaginosis and chlamydial infection can cause a partial activation of systemic cytokine network and contribute to the occurrence of preterm delivery.

    Full Text Available Studies on ligand binding potential of glycyrrhizic acid, a potential agonist to PPARγ, displayed encouraging results in amelioration of metabolic syndrome. The regulation of gene cassettes by PPARγ affects glucose homeostasis, lipid, lipoprotein metabolism and adipogenesis. This study was performed to determine the effects of GA on total PPARγ and LPL expression levels, lipid parameters and HOMA-IR. Oral administration of 100 mg/kg GA for 24 hours resulted in an increase in insulin sensitivity with decreases in blood glucose, serum insulin and HOMA-IR. Improvement in serum lipid parameters was also observed with a decrease in triacylglycerol, total cholesterol and LDL-cholesterol and an elevation in HDL-cholesterol. GA administration also resulted in up-regulation of total PPARγ and LPL expression levels in the visceral and subcutaneous adipose tissues, abdominal and quadriceps femoris muscles, as well as liver and kidney, with a significant up-regulation only in the visceral adipose tissue, abdominal and quadriceps femoris muscles. Thus, oral administration of 100 mg/kg GA for 24 hours improved insulin sensitivity and lipid profiles and induced upregulation of total PPARγ and LPL expression levels in all studied tissues.

    Full Text Available This prospective study was designed to investigate the relationship between lipids levels in both serum and seminal plasma and semen parameters.631 subfertile men were enrolled. Their obesity-associated markers were measured, and semen parameters were analyzed. Also, seminal plasma and serum TC, TG, HDL and LDL and serum FFA, FSH, LH, total testosterone (TT, estradiol (E2 and SHBG levels were detected.Seminal plasma and serum TG, TC and LDL levels were positively related to age. Serum TC, TG and LDL were positively related to obesity-associated markers (P < 0.001, while only seminal plasma TG was positively related to them (P < 0.05. For lipids levels in serum and seminal plasma, only TG level had slightly positive correlation between them (r = 0.081, P = 0.042. There was no significant correlation between serum lipids levels and semen parameters. However, seminal plasma TG, TC, LDL and HDL levels were negatively related to one or several semen parameters, including semen volume (SV, sperm concentration (SC, total sperm count (TSC, sperm motility, progressive motility (PR and total normal-progressively motile sperm counts (TNPMS. Moreover, seminal plasma TG, TC, LDL and HDL levels in patients with oligospermatism, asthenospermia and teratozoospermia were higher than those with normal sperm concentration, motility or morphology. After adjusting age and serum LH, FSH, TT, E2 and SHBG levels, linear regression analysis showed that SV was still significantly correlated with seminal plasma LDL (P = 0.012, both of SC and TSC with seminal plasma HDL (P = 0.028 and 0.002, and both of PR and sperm motility with seminal plasma TC (P = 0.012 and 0.051.The abnormal metabolism of lipids in male reproductive system may contribute to male factor infertility.

    Low-fat diets increase serum triacilglycerol and decrease HDL-cholesterol concentrations, thereby potentially adversely affecting cardiovascular disease (CVD) risk. The present study compared the CVD risk profi le of a high-MUFA diets (olive oil) and high-PUFA diets (pumpkin seed oil). The most signifi cant difference between the two groups was that the atherogenic index in groups given olive oil was significantly lower (for approximately 60 %) than atherogenic index recorded in control group...

    The differences between the effects of high- and low-intensity exercise training on cardiorespiratory system and serum lipid levels were examined under conditions in which the total work load was same. Twenty-two healthy, untrained female students, aged 18 to 24 years, participated in the 8-week training experiment. Two training groups exercised on bicycle ergometers 4-5d/wk for 8 wk with high-intensity (H: 70% VO2 max 13 min/session; N = 8) or in low-intensity (L: 36% VO2 max 33 min/session; N = 8). The control group (C: N = 6) continued its sedentary life style. Data of 6 students (H: N = 2, L: N = 2, C: N = 2) were excluded from the analysis, because they did not carry out their duties. The results of this study were as follows; 1) Aerobic capacity increased in both training groups. 2) After training, both heart rates and oxygen uptake during submaximal work loads significantly decreased in group H, but only heart rates significantly decreased in group L. 3) Heart rates with a same oxygen-uptake load during submaximal work seemed to increase in group H, but significantly decreased in group L. 4) The mechanical efficiency during the submaximal work load significantly increased in group H, but not in group L. 5) DBP and MBP during the submaximal work load in group L significantly decreased compared with those before the training. SBP with a same oxygen-uptake load during submaximal work increased in group H, but decreased in group L. 6) Rate pressure products both at rest and during submaximal exercise decreased significantly in group L. 7) Serum lipid levels remained in all groups. These results suggested that when the amount of exercise is the same, low-intensity exercise training with 35% VO2 max was more effective to increase endurance capacity and was safer than high-intensity exercise training.

    Full Text Available Sudden sensorineural hearing loss (SSNHL is a relatively common condition that is usually of unknown etiology. A number of individual studies have investigated the association between various serum lipids and SSNHL; however, the findings have been inconsistent. In an attempt to obtain more definitive information on the relationship between serum lipids and SSNHL, we carried out a systematic review and meta-analysis.Medline, the Cochrane Library, and EMBASE were searched using the following key words: lipid, cholesterol, triglyceride, fat, serum, blood, sudden hearing loss, hearing loss, hearing disorders. Randomized controlled trials, prospective cohort studies, and retrospective case-control studies involving patients with SSNHL and healthy controls that examined the relationship (reported as odds ratios [OR] between lipid profiles and SSNHL were included. Primary outcomes were total cholesterol and low-density lipoprotein cholesterol (LDL-C concentrations. Secondary outcomes were triglyceride, high-density lipoprotein cholesterol, and lipoprotein(a concentrations.A total of 6 case-control studies were included in this systematic review/meta-analysis. The total number of participants ranged from 30 to 250 in the case group and from 43 to 271 in the control group. Meta-analysis revealed no significant difference in total cholesterol levels between the case and control groups (pooled OR = 1.79, 95% confidence interval [CI] = 0.98 to 3.26, P = 0.057. Likewise, meta-analysis revealed no significant difference in LDL-C concentrations between the case and control groups (pooled OR = 1.15, 95% CI = 0.64 to 2.07, P = 0.639. Since there were an insufficient number of studies reporting data for the secondary outcomes, meta-analysis was not possible.Our results do not provide evidence for serum lipids being associated with SSNHL, nor do they definitively rule out such an association. Additional studies are needed to ascertain the relationship, or lack

    Full Text Available Background. Metabolic syndrome has been linked to an increased cancer risk, but the role of dyslipidaemia in gastrointestinal malignancies is unclear. We aimed to assess the risk of oesophageal, stomach, colon, and rectal cancers using serum levels of lipid components. Methods. From the Swedish Apolipoprotein Mortality Risk (AMORIS study, we selected 540,309 participants (> 20 years old with baseline measurements of total cholesterol (TC, triglycerides (TG, and glucose of whom 84,774 had baseline LDL cholesterol (LDL, HDL cholesterol (HDL, apolipoprotein B (apoB, and apolipoprotein A-I (apoA-I. Multivariate Cox proportional hazards regression was used to assess glucose and lipid components in relation to oesophageal, stomach, colon, and rectal cancer risk. Results. An increased risk of oesophageal cancer was observed in persons with high TG (e.g. HR: 2.29 (95% CI: 1.42–3.68 for the 4th quartile compared to the 1st and low LDL, LDL/HDL ratio, TC/HDL ratio, log (TG/HDL, and apoB/apoA-I ratio. High glucose and TG were linked with an increased colon cancer risk, while high TC levels were associated with an increased rectal cancer risk. Conclusion. The persistent link between TC and rectal cancer risk as well as between TG and oesophageal and colon cancer risk in normoglycaemic individuals may imply their substantiality in gastrointestinal carcinogenesis.

    We investigated the effects of Antep pistachio on International Index of Erectile Function (IIEF) scores, penile color Doppler ultrasound (PCDU) parameters and serum lipid levels in patients with ED. A total of 17 married male patients with ED for at least 12 months were included in this prospective study. Patients were put on a 100 g pistachio nuts diet for 3 weeks. IIEF and PCDU were evaluated before and after the pistachio diet. In addition, plasma total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglyceride were measured before and after dietary modifications from all subjects. Mean IIEF-15 score was 36 ± 7.5 before the diet and 54.2 ± 4.9 after the diet (P=0.001). Similarly, an increase in all five domains of IIEF was observed after the diet (Ppistachio diet were 35.5 ± 15.2 and 43.3 ± 12.4 cm s(-1), respectively (P=0.018). After the pistachio diet, TC and LDL levels decreased significantly, whereas HDL level increased (P=0.008, 0.007 and 0.001, respectively). We demonstrated that a pistachio diet improved IIEF scores and PCDU parameters without any associated side effects in patients with ED. Furthermore, the lipid parameters showed statistically significant improvements after this diet.

    Full Text Available The gap in mortality between patients with rheumatoid arthritis (RA and the general population (1.5–3.0 fold risk is increasing. This disparity is attributable mainly to cardiovascular disease (CVD, as the CVD risk is comparable to patients with diabetes mellitus. The purpose of this study is to determine whether borage seed oil rich in gamma-linolenic acid, fish oil rich in eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA, or the combination of both oils are useful treatments for dyslipidemia in patients with RA. We randomized patients into a double blind, 18 month trial. Mixed effects models were used to compare trends over time in serum lipids. No significant differences were observed between the three groups: All three treatment groups exhibited similar meaningful improvement in the lipid profile at 9 and 18 months. When all groups were combined, these treatments significantly reduced total and LDL-cholesterol and triglycerides, increased HDL-cholesterol, and improved the atherogenic index. All improvements observed at 9 months persisted at 18 months (P<0.001 verses baseline. Conclusion. Marine and botanical oils may be useful treatment for rheumatoid arthritis patients who are at increased risk for cardiovascular disease compared to the general population.

    The postprandial regulation of progranulin by oral uptake of lipids and carbohydrates in healthy individuals has not yet been investigated. The regulation of progranulin in 2 large cohorts of healthy volunteers during oral lipid tolerance test (OLTT; n=100) and oral glucose tolerance test (OGTT; n=100) was analyzed. One hundred healthy volunteers underwent OLTT and OGTT in an outpatient setting. Venous blood was drawn at 0 hours (h) (fasting) and at 2, 4, and 6 h in OLTT or 1 and 2 h in OGTT. A novel OLTT solution completely free of carbohydrates and protein was applied. Subjects were characterized by anthropometric and laboratory parameters. Serum concentrations of progranulin were measured by enzyme-linked immunosorbent assay (ELISA). Circulating progranulin levels remained unchanged during OLTT and OGTT. Fasting progranulin levels ranged between 31.3±8.7 and 40.6±7.7 ng/ml and were not different in subgroups addressing BMI, gender, family history, smoking habits, and hormonal contraception. There was a reciprocal correlation of progranulin with HDL (negative) and LDL cholesterol levels (positive). In healthy adults, fasting and postprandial circulating progranulin levels are not different in BMI subgroups. Oral uptake of carbohydrates and lipids does not influence circulating progranulin levels in a short-term manner. A postprandial and short-term regulation of this adipokine is absent, at least in healthy subjects. There is a negative correlation of progranulin with HDL cholesterol, but a positive correlation with LDL cholesterol. This reciprocal association might be of physiological importance for an individual's atherosclerotic risk. PMID:25565096

    Full Text Available BACKGROUND AND OBJECTIVE: Type II diabetes mellitus (T2DM often have both quantitative and qualitative abnormalities of lipoproteins that are responsible for increased incidence of microvascular and macrovascular complications. Incidence of coronary heart disease is three to four folds higher in patients with type 2 diabetes mellitus compared to non - diabetics. It has been proposed that the composition of lipid particles in diabetic dyslipidemia is more atherogenic than other types of dyslipidemia. This study was conducted to asses s serum lipid profile in type diabetes male and female patients. MATERIALS AND METHODS: This study was conducted on 50 T2DM patients with history more than ten yrs diabetes. Diabetic patients with overt complications and patients on drugs like diuretics, s teroids, oral contraceptives and beta blockers etc are excluded from study. 5 ml of whole blood was collected via vena puncture with the help of a disposable syringe in between 7.00am and 8.00am. Fasting plasma glucose and different Lipid fractions were es timated using standard procedure. All values were expressed as mean ± S.D. Statistical significance of differences between control and study groups were evaluated by student’s t test. A p - value less than 0.05 were considered as significant. RESULTS: The se rum total cholesterol, LDL cholesterol and triglycerides were significantly raised in both males and females . CONCLUSION: Hyperlipidaemia is a common finding among DM patients. DM patients should be screened and appropriate management should be instituted to reduce the risk of CHD and atherosclerosis

    Full Text Available Dyslipidemia is major problem among population those have sedentary life style as well as in diabetics. Bougainvillea spectabilis is most commonly found in India as an ornamental plant and has got anti-diabetic action due to presence of one insulin mimicking agent D-pinitol (3-O-methyl-chiroinositol. The present investigation was undertaken to evaluate the effect of alcoholic extract of leaves of Bougainvillea spectabilis (AEBSL on serum lipid profile in albino rats fed with high fat diet (HFD and to compare it with a standard hypolipidaemic drug simvastatin. Thirty healthy albino rats of both sexes (100-200 g were randomized into 5 groups of 6 animals each. The groups were treated as follows: Group A: normal diet (ND; Group B: HFD (vanaspati ghee + coconut oil mixture in ratio of 3:2 at 10 ml/kg/day; Group C: HFD+ AEBSL (100 mg/kg/day; Group D: HFD + AEBSL (200 mg/kg/day; Group E: HFD + simvastatin (1.8 mg/kg/day. Lipid profile was estimated after 8 weeks of treatment. AEBSL showed a significant (p<0.01 reduction in total cholesterol (TC, Triglyceride (TG, Low density lipoprotein (LDL, Very low density lipoprotein (VLDL levels and significant (p<0.01 increase in high density lipoproteins (HDL in hypercholesteromic rats (Group C and Group D. AEBSL 200 mg/kg/day found to be more effective than AEBSL 100 mg/kg/day. There is also significant improvement in atherogenic index (p<0.01 and increases the percentage of protection AEBSL treated animals. Alcoholic extract of leaves of Bougainvillea spectabilis leaves have excellent lipid lowering potentiality.

    Milk fat contains considerable amounts of saturated fatty acids, known to increase serum cholesterol. Little is known, however, about the relative effect of different milk products on risk factors for CHD. The aim of the present study was to compare the effects of Jarlsberg cheese (a Norwegian variety of Swiss cheese) with butter on serum lipoproteins, haemostatic variables and homocysteine. A controlled dietary study was performed with twenty-two test individuals (nine men and thirteen women) aged 23-54 years. The subjects consumed three isoenergetic test diets, with equal amounts of fat and protein, and containing either cheese (CH diet), butter + calcium caseinate (BC diet) or butter + egg-white protein (BE diet). The study was a randomised cross-over study and the subjects consumed each diet for 3 weeks, with 1 week when they consumed their habitual diet in between. Fasting blood samples were drawn at baseline and at the end of each period. Serum was analysed for lipids and plasma for haemostatic variables and homocysteine. Total cholesterol was significantly lower after the CH diet than after the BC diet (-0.27 mmol/l; P=0.03), while the difference in LDL-cholesterol was found to be below significance level (-0.22 mmol/l; P=0.06). There were no significant differences in HDL-cholesterol, triacylglycerols, apo A-I, apo B or lipoprotein (a), haemostatic variables and homocysteine between the diets. The results indicate that, at equal fat content, cheese may be less cholesterol increasing than butter.

    Full Text Available The purpose of this study was to evaluate cereals and nata de coco supplementation on the lipid status in 22 subjects with hyperlipidemia. Subjects consisted of eleven men and eleven women aged 32-75 years, and had serum total cholesterol (TC level of >5.2 mmol/L, serum total triglyceride (TG level of >1.7 mmol/ L and low density lipoprotein-cholesterol (LDL-c level of >3.4 mmol/L. The study consisted of four weeks of control and 20 weeks of supplementation period. The subjects were given 15 g of the supplement twice daily for 20 weeks. The daily 30 g supplement consisted of unpolished rice, hulled mung bean, sweet corn, and nata de coco and provided 122.6 kcal, 5.5 g of protein, 0.5 g of fat, 24.1 g of carbohydrate and 2.7 g of dietary fiber. After 20 weeks, the subjects were divided into two groups, according to their dietary compliance, group A: > 90% compliance, and group B: < 90% compliance with the assigned supplement intake. There were 15 subjects in group A, and 7 in group B. Results showed that in group A the mean TG levels at weeks 4, 8, and 16 were significantly different (P<0.05, but no significant differences were observed in TC, LDL-c and HDL-c except that TC level at week 16 was significantly lower than that at week 0 (P<0.05. Thus, the results appeared to indicate that health food from unpolished rice, hulled mung bean, sweet corn and nata de coco may reduce the serum TG and TC in hyperlipidemic patients.

    Full Text Available Introduction: Successfully treated HIV-infected patients may still have an increased risk for cardiovascular morbidity and mortality, which might be related not only to traditional risks, but also to inflammation and dyslipidemia induced by HIV and/or antiretroviral therapy [1, 2]. We examined the relationship of serum lipid levels with plasma biomarkers of inflammation using a composite inflammatory burden score (IBS from the following seven markers of inflammation: CD40L, tPA, MCP-1, IL-8, IL-6, hCRP and P-selectin. Materials and Methods: Subjects were selected among consecutive HIV-infected males ≥18 years of age with an undetectable viral load (75th percentile were considered elevated and an IBS was constructed as the presence of zero, one, two, or three or more elevated biomarkers. Correlations between the IBS and lipid parameters were examined using Spearman's Rho and by ordered logistic regression proportional odds model to estimate the odds of more elevated (>75th percentile biomarkers. Results: 181 male patients were included into the study, the median age was 46.7 (Q1–Q3, 39.9–55.0 years and the median current CD4 cell count was 553.0 (Q1–Q3, 389–729 per microliter. The patients were mainly treated with two nucleoside reverse transcriptase inhibitor (NRTI plus one non-NRTI (NNRTI (N=100, 60.8% or two NRTI plus lopinavir (N=50, 27.6%. There was a significant correlation between the IBS and serum cholesterol (Rho=0.23, 95% CI, 0.09–0.37, triglycerides (Rho=0.30, 95% CI, 0.16–0.42 and cholesterol/HDL-cholesterol ratio (Rho=0.25, 95% CI 0.11–0.38. In the multivariable model a one unit increase in cholesterol/HDL-cholesterol ratio was associated with a 1.72-fold (95% CI, 1.27–2.33 increased odds of having a greater IBS. One unit increase (mmol/L of cholesterol and triglycerides was associated with a 1.41-fold (95% CI, 1.13–1.76 and 1.37-fold (95% CI, 1.18–1.60 increased odds of having a greater IBS, respectively

    Introduction Dyslipidemia is often detected in patients with chronic kidney disease (CKD). Previous studies of the relationship between lipid profiles and kidney function have yielded variable results. We aimed to investigate the correlation between serum lipid levels and kidney function evaluated by measured glomerular filtration rate (mGFR) in Chinese patients with CKD. Methods A cross-sectional study was conducted on 2036 Chinese CKD patients who had mGFR. Linear regression analysis was performed to evaluate the correlation between different serum lipid levels and mGFR, while logistic regression analysis was used to investigate the association between CKD stages and the risk of different types of dyslipidemia. Results The mean age was 55 years and the mean mGFR was 63 mL/min/1.73m2. After adjusting for some confounders (age, gender, body mass index, a history of diabetes, fasting glucose, a history of hypertension, systolic blood pressure, diastolic blood pressure, smoking status, hemoglobin, serum potassium, serum albumin, and serum uric acid), serum triglyceride level showed a negative correlation with mGFR (β = -0.006, P = 0.006) in linear regression analysis, and CKD stages were positively related to the risk of hypertriglyceridemia (odds ratios were 1.329, 1.868, 2.514 and P were 0.046, < 0.001, < 0.001 for CKD stage 2, 3, 4/5, respectively) in logistic regression anlysis. Conclusions Serum triglyceride level is independently association with mGFR. Patients with reduced kidney function are more likely to have higher serum triglyceride levels. Further longitudinal, multicenter and well-conducted studies are needed to provide more evidence. PMID:27695128

    Full Text Available The objective of the present study was to detect the association of the rs4731702 single nucleotide polymorphism (SNP and serum lipid levels in the Guangxi Mulao and Han populations. A total of 727 subjects of Mulao and 740 subjects of Han Chinese were included. Serum low-density lipoprotein cholesterol (LDL-C and apolipoprotein (Apo B levels were higher in Mulao than in Han (P<0.05. The T allele carriers had higher serum LDL-C and ApoAI levels in Mulao, whereas they had lower high-density lipoprotein cholesterol (HDL-C levels and ratio of ApoAI to ApoB in Han (P<0.05 than the T allele noncarriers. Subgroup analyses showed that the T allele carriers had higher HDL-C, LDL-C, and ApoAI levels in Mulao males and lower ApoAI levels and ratio of ApoAI to ApoB in Han males than the T allele noncarriers. The subjects with TT genotype in Han females also had higher total cholesterol, LDL-C, ApoAI, and ApoB levels than the subjects with CT or CC genotype. Serum lipid parameters were also correlated with several environmental factors in both ethnic groups. The differences in the association of KLF14 rs4731702 SNP and serum lipid levels between the two ethnic groups might partly result from different gene-environmental interactions.

    Full Text Available Abstract Background There are two main playing positions in rugby (backs and forwards, which demonstrate different exercise patterns, roles, and physical characteristics. The purpose of this study was: 1 to collect baseline data on nutrient intake in order to advise the athletes about nutrition practices that might enhance performance, and 2 to compare serum lipids, lipoproteins, apolipoproteins (apo, lecithin:cholesterol acyltransferase (LCAT activity, and iron status of forwards and backs. Methods The sporting group was divided into 18 forwards and 16 backs and were compared with 26 sedentary controls. Dietary information was obtained with a food frequency questionnaire. Results There were significant differences among the three groups. The forwards had the highest body weight, body mass index, percentage of body fat (calculated by sum of four skinfold thicknesses, as well as the highest lean body mass, followed by the backs and the control group. The mean carbohydrate intake was marginal and protein intake was lower than the respective recommended targets in all three groups. The mean intakes of calcium, magnesium, and vitamins A, B1, B2, and C were lower than the respective Japanese recommended dietary allowances or adequate dietary intakes for the rugby players. The forwards had significantly lower high-density lipoprotein cholesterol (HDL-C and HDL2-C than the backs and had significantly higher apo B and LCAT activity than the controls. The backs showed significantly higher HDL-C, HDL3-C, low-density lipoprotein cholesterol, and apo A-I, and LCAT activity than the controls. Four forwards (22%, five backs (31%, and three controls (12% had hemolysis. None of the rugby players had anemia or iron depletion. Conclusion The findings of our study indicate that as the athletes increased their carbohydrate and protein intake, their performance and lean body mass increased. Further, to increase mineral and vitamin intakes, we recommended athletes

    Cadmium is one among the most environmental pollutants that affects many organs like kidney, liver and testis. The present study was aimed to assess the simultaneous effects of black tea extracts (BTE) on cadmium chloride induced alterations in lipid profile and liver histology. Adult rats were divided into four groups (n=6/group), group I (normal saline), group II (CdCl2, 1.0 mg/kg, b.wt; i.p), group III (black tea extract, 2.5 gm tea leaf/dl of water that is 2.5% of aqueous BTE) and group IV (cadmium chloride + BTE). Cadmium chloride intoxicated rats showed significant increase in serum total cholesterol, triglycerides, and low density lipoprotein-cholesterol and there is a significant decrease in the serum high density lipoprotein-cholesterol. In the liver, cadmium chloride showed changes in normal architecture, swollen hepatocytes, kupffer cells hyperplasia, dilation and congestion of central vein. Oral administration of black tea extracts with cadmium chloride significantly improves lipid profile and liver architecture as compared to the cadmium chloride group. The results indicate that BTE is beneficial in preventing cadmium-induced lipid alterations and hepatocellular damage.

    Serum lipid management in patients aged ≥ 75 has not been precisely explored. We, therefore, compared the serum lipid management between the two age groups with and without coronary heart disease (CHD). We, therefore, retrospectively reviewed medical charts of patients who were hospitalized in the departments of internal medicine during a period of 14 months. Serum lipid goal attainment was explored by applying the lipid goals for patients aged < 75 to those aged ≥ 75. In 1988 enrolled patients, 717 subjects (36.1%) were aged ≥ 75. Among them, 41.3% and 32.4% of the patients had CHD, 44.2% and 41.0% were primary prevention at high-risk, and 14.5% and 14.6% were primary prevention at moderate-risk in patients aged ≥ 75 and aged < 75, respectively. Serum LDL-C goal achievement rates in CHD were 66.9% and 65.0% in patients aged ≥ 75 and < 75, respectively (p = 0.334). In the primary prevention at high-risk, these rates were 73.5% and 63.3%, in patients aged ≥ 75 and < 75, respectively (p = 0.001). They were 77.9% and 58.1% in primary prevention at moderate-risk aged ≥ 75 and < 75, respectively (p < 0.001). In CHD, lipid-lowering medication subscription rates were significantly lower in patients aged ≥ 75 (60.1%) than those aged < 75 (73.8%, p < 0.001). In conclusion, in CHD, serum lipid goal attainment was comparable between the two age groups although the lipid-lowering drugs were less frequently prescribed in patients aged ≥ 75. Without CHD, it was significantly better in patients aged ≥ 75 than those aged < 75 although the lipid-lowering drug subscription rates were comparable between the two age groups. PMID:27413682

    Full Text Available BACKGROUND: Fibroblast growth factor 21 (FGF-21 is a metabolic regulator with multiple beneficial effects on glucose homeostasis and lipid metabolism in animal models. The relationship between plasma levels of FGF-21 and coronary heart disease (CHD in unknown. METHODOLOGY/PRINCIPAL FINDINGS: This study aimed to investigate the correlation of serum FGF-21 levels and lipid metabolism in the patients with coronary heart disease. We performed a logistic regression analysis of the relation between serum levels of FGF-21 and CHD patients with and without diabetes and hypertension. This study was conducted in the Departments of Endocrinology and Cardiovascular Diseases at two University Hospitals. Participants consisted of one hundred and thirty-five patients who have been diagnosed to have CHD and sixty-one control subjects. Serum FGF-21 level and levels of fasting blood glucose; triglyceride; apolipoprotein B100; HOMA-IR; insulin; total cholesterol; HDL-cholesterol; LDL-cholesterol; and C-reactive protein were measured. We found that median serum FGF-21 levels were significantly higher in CHD than that of control subjects (P<0.0001. Serum FGF-21 levels in CHD patients with diabetes, hypertension, or both were higher than that of patients without these comorbidities. Serum FGF-21 levels correlated positively with triglycerides, fasting blood glucose, apolipoprotein B100, insulin and HOMA-IR but negatively with HDL-C and apolipoprotein A1 after adjusting for BMI, diabetes and hypertension. Logistic regression analysis demonstrated that FGF-21 showed an independent association with triglyceride and apolipoprotein A1. CONCLUSIONS/SIGNIFICANCE: High levels of FGF-21 are associated with adverse lipid profiles in CHD patients. The paradoxical increase of serum FGF-21 in CHD patients may indicate a compensatory response or resistance to FGF-21.

    Full Text Available Abstract Background The prevalence and risk of cardiovascular disease increase after menopause in correlation with the progression of abnormality in the serum lipid profile and the deprivation of estrogen. Erxian decoction (EXD, a Chinese medicinal formulation for treating menopausal syndrome, stimulates ovarian estrogen biosynthesis. This study investigates whether EXD improves the serum lipid profile in a menopausal rat model. Methods Twenty-month-old female Sprague Dawley rats were treated with EXD and its constituent fractions. Premarin was administered for comparison. After eight weeks of treatment, rats were sacrificed and the serum levels of total cholesterol, triglyceride, high-density-lipoprotein cholesterol and low-density-lipoprotein cholesterol were determined. The hepatic protein levels of 3-hydroxy-3-methyl-glutaryl-CoA reductase and low-density-lipoprotein receptor were assessed with Western blot. Results The serum levels of total cholesterol and low-density-lipoprotein cholesterol were significantly lower in the EXD-treated group than in the constituent fractions of EXD or premarin groups. However, the serum levels of triglyceride and high-density-lipoprotein cholesterol were not significantly different from the control groups. Results from Western blot suggest that EXD significantly down-regulated the protein level of 3-hydroxy-3-methyl-glutaryl-CoA reductase and up-regulated low-density-lipoprotein receptor. Conclusion EXD improves serum lipid profile in a menopausal rat model through the suppression of the serum levels of total cholesterol and low-density-lipoprotein cholesterol, possibly through the down-regulation of the 3-hydroxy-3-methyl-glutaryl-CoA and up-regulation of the low-density-lipoprotein receptor.

    Full Text Available Background: The present study was undertaken to estimate and compare the levels of plasma total cholesterol (TC, low density lipoprotein (LDL, high density lipoprotein (HDL, very low density lipoprotein (VLDL and triglycerides in patients with oral precancerous lesions/conditions, oral cancer and normal subjects. Materials and Methods: The study comprised of 60 patients with oral precancerous lesions/conditions, 60 patients with oral cancer and a control group of 60 healthy individuals. The diagnosis of oral precancerous lesions/conditions and oral cancer was confirmed histopathologically. Under aseptic condition 5 ml venous blood of overnight fasting patient was withdrawn from each individual. Serum was separated by centrifugation and plasma levels of TC, LDL, HDL, VLDL and triglycerides were estimated. Descriptive statistical analysis has been carried out in the present study. Analysis of variance has been used to find the significance of study parameters between three or more groups of patients, Post-hoc test as Tukey has been used to find the pair wise significance. Significance is assessed at 5% level of significance. Results: Statistically significant decrease in levels of plasma TC, LDL, HDL, VLDL and triglycerides was observed in the precancerous and cancerous groups as compared to the control group. On comparison between precancerous and cancerous groups, significant decrease was observed in cancerous group. Conclusion: The change in lipid levels may have an early diagnostic or prognostic role in the oral premalignant lesions/conditions and oral cancer. The presence of decreased plasma lipid profile should increase the suspicion of these lesions to be investigated further.

    Full Text Available Introduction: High plasma cholesterol levels, mainly LDL are a widely recognized major risk factor for Coronary Heart Disease (CHD. According to the epidemiologic studies findings, people from the Mediterranean countries, have lower CHD rats than other countries, in these countries usual diet is high in olive oil. The present study compares the effects of cholesterol enriched diet with or without adding olive oil on serum Lipoproteins, lipid per oxidation, and atherosclerosis development. Method: Twenty Dutch male rabbits were Categorized to four groups (one group as Control, and others as Experimental. They received one of standard, cholesterol - rich, olive oil rich and combined (cholesterol + olive oil diet for Twelve weeks. Fasting blood samples from heart were collected at the beginning, and the end of Experimental period. Means of total cholesterol, HDL-Ctriglycerides, MDA and antioxidant caperimental period, significant differences were showed in total cholesterol, HDL-C, triglyceride and MDA between groups. Results: The comparison of cholesterol rich diet with cholesterol + olive oil showed a higher mean of MDA in cholesterol rich group (P < 0.001. Biochemical factors and aortic lesion degree showed no significant difference between standard and olive oil group. Aortic lesions in cholesterol + olive oil showed nonsignificant lower degree than cholesterol group. Discussion: This findings showed preventive effect of olive oil against atherosclerosis which is independent of plasma lipoprotein effect, and suggested that probably olive oil acts on arteries directly.

    Full Text Available This study evaluated the nutritional value of sesame and flaxseed oils and their effects on the lipid and glucose profile of rats fed diets containing different fat combinations. Fatty acid composition, refractive index, and iodine and saponification values were analyzed to characterize the oils. In the biological assay, Wistar rats were fed different diets, whose fat composition consisted of varying combinations of flaxseed oil, sesame oil, and animal fat. The primary constituents of the sesame oil were oleic (28.6%, linoleic (28.4%, and lauric acid (14.6%; for the flaxseed oil they were alpha-linolenic (39.90%, oleic (17.97% and linoleic acid (12.25%. The iodine and saponification values of the oils were within the reference range. Rats fed flaxseed oil-based diets had the lowest serum cholesterol values, whereas rats fed diets with flaxseed oil + sesame oil + animal fat had the highest glucose levels. HDL levels decreased significantly with flaxseed oil. Sesame and flaxseed oils are sources of polyunsaturated fatty acids (PUFA, and the flaxseed oil-based diet had a hypocholesterolemic effect, whereas sesame oil showed oxidative stability since it contains high levels of monounsaturated and saturated fatty acids.

    Full Text Available Cigarette smoke-induced oxidative stress leads to dyslipidemia and systemic inflammation. Morinda citrifolia (noni fruit juice has been found previously to have a significant antioxidant activity. One hundred thirty-two adult heavy smokers completed a randomized, double blind, placebo-controlled clinical trial designed to investigate the effect of noni juice on serum cholesterol, triglyceride, low density lipoprotein cholesterol (LDL, high density lipoprotein cholesterol (HDL, high-sensitivity C-reactive protein (hs-CRP, and homocysteine. Volunteers drank noni juice or a fruit juice placebo daily for one month. Drinking 29.5 mL to 188 mL of noni juice per day significantly reduced cholesterol levels, triglycerides, and hs-CRP. Decreases in LDL and homocysteine, as well increases in HDL, were also observed among noni juice drinkers. The placebo, which was devoid of iridoid glycosides, did not significantly influence blood lipid profiles or hs-CRP. Noni juice was able to mitigate cigarette smoke-induced dyslipidemia, an activity associated with the presence of iridoids.

    Objectives To investigate the relationship of serum leptin concentration with the lipids and body mass index (BMI) in patients with chronic congestive heart failure(CHF). Methods The serum concentration of leptin in 39 patients with CHF (14 in cardiac function class Ⅱ , 21 in class Ⅲ , 4 in class Ⅳ , NYHA) and in 46 patients with cardiac function class Ⅰ (NYHA) were assessed by radioimmunoassay. Results The serum concentration of leptin were 9.018±4.519μg/l in CHF group (cardiac function class Ⅱ 11.492±5.649 μg/l, class Ⅲ 7.763±3.321 μg/l, class Ⅳ 6.100±2.657 μg/l);11.674±6.911 μg/l in class Ⅰ group. The serum concentrations of leptin were significantly lower in CHF group, as compared with class Ⅰ group (P<0.05). Moreover, the decrease of serum leptin concentration was significantly correlated with the decreased serum concentrations of total cholesterol, triglyceride, body mass index and left ventricular ejection fraction in CHF group, respectively (P<0.05). Conclusions The significance of the decrease in serum leptin in CHF patients needs further study.

    Despite the well-documented role of calcium in cell metabolism, its role in the development of cardiovascular disease is still under heavy debate. Several studies suggest that calcium supplementation might be associated with an increased risk of coronary heart disease, whereas others underline a significant effect on lowering high blood pressure and hyperlipidemia. The purpose of this study was to investigate, in a large nonselected cohort from South Italy, if serum calcium levels correlate with lipid values and can therefore be linked to higher individual cardiovascular risk.Eight-thousand-six-hundred-ten outpatients addressed to the Laboratory of Clinical Biochemistry, University of Magna Græcia, Catanzaro, Italy from January 2012 to December 2013 for routine blood tests, were enrolled in the study. Total HDL-, LDL- and non-HDL colesterol, triglycerides, and calcium were determined with standard methods.We observed a significant association between total cholesterol, LDL-cholesterol, HDL-cholesterol, non-HDL cholesterol, triglycerides, and serum calcium in men and postmenopause women. Interestingly, in premenopause women, we only found a direct correlation between serum calcium, total cholesterol, and HDL-cholesterol. Calcium significantly increased while increasing total cholesterol and triglycerides in men and postmenopause women.Our results confirm that progressive increase of serum calcium level correlates with worsening of lipid profile in our study population. Therefore, we suggest that a greater caution should be used in calcium supplement prescription particularly in men and women undergoing menopause, in which an increase of serum lipids is already known to be associated with a higher cardiovascular risk.

    Full Text Available AIM: Mortality due to cardiovascular disorders is highest among all non-communicable diseases. Smoking is one of the modifiable risk factors for the development of this condition. Total Cholesterol (TC and Triglycerides (TG in serum being independent biomarkers of CVD, this study was designed to analyze and compare their levels between smokers and non-smokers. MATERIALS and METHODS: The study included 15 smokers who smoked continuously 5-7 cigarettes per day for around 5 years and five non-smokers as controls who were believed to be void of other CVD risk factors. Venous blood was collected from the selected individuals and sera was aspirated after centrifugation.The obtained sera were freeze stored and used later to estimate the total cholesterol and triglycerides by standard protocols.RESULTS and DISCUSSION: The study found that the mean value of TC among smokers and nonsmokers were not different from each other. This may be because the screened populations were nascent smokers andalso due to the fact that they were of young age. In case of TG, slightly lower mean value was noticed when compared to that of controls. The reason for this is not clear and requires further studies on more number of smokers in this age group. CONCLUSION: This study is unique as there are very few literature reports on lipid values among the population in the age group of 20-25 years with approximate 5 years of smoking history. It is inferred here thatin this age group, smoking around 5-6 cigarettes does not alter the blood cholesterol and triglyceride levels significantly. However to validate these results it is proposed in future to extend the analysis to more number of samples.

    This study was conducted to investigate the effects of dietary coconut oil as a medium-chain fatty acid (MCFA) source on performance, carcass composition and serum lipids in male broilers. A total of 540, one-day-old, male Arbor Acres broilers were randomly allotted to 1 of 5 treatments with each treatment being applied to 6 replicates of 18 chicks. The basal diet (i.e., R0) was based on corn and soybean meal and was supplemented with 1.5% soybean oil during the starter phase (d 0 to 21) and 3.0% soybean oil during the grower phase (d 22 to 42). Four experimental diets were formulated by replacing 25%, 50%, 75%, or 100% of the soybean oil with coconut oil (i.e., R25, R50, R75, and R100). Soybean oil and coconut oil were used as sources of long-chain fatty acid and MCFA, respectively. The feeding trial showed that dietary coconut oil had no effect on weight gain, feed intake or feed conversion. On d 42, serum levels of total cholesterol, low-density lipoprotein cholesterol, and low-density lipoprotein/high-density lipoprotein cholesterol were linearly decreased as the coconut oil level increased (pcoconut oil level increased (poil in diets with coconut oil is the optimum level to reduce fat deposition and favorably affect lipid profiles without impairing performance in broilers.

  1. Analysis of serum lipid profiles, metal ions and thyroid hormones levels abnormalities in - thalassaemic children of Bangladesh

    International Nuclear Information System (INIS)

    Objective: To assess the serum lipid profile of cardiovascular disease free male and female children with - thalassaemia. Levels of zinc, copper and magnesium in the serum were also determined along with the Thyroid profile. Methods: From January to December 2007, we enrolled 121 consecutive patients with -thalassaemia that visited The Thalassaemia Center at Dhaka Shishu (Children) Hospital, Bangladesh every month for routine examinations. Fasting blood lipid levels were measured in all participants. Zinc, Copper and Magnesium levels in serums were determined. Thyroid function was also assessed by evaluating T3, T4 and TSH levels. Results: Of the 121 patients, 65 were males (10.14 +- 3.91 years) and 56 were females (9.08 +- 4.32 years). Data analysis revealed that 2.0% males and 4.35% females had high total serum cholesterol, and 28.57% males and 21.74% females had high triglyceride levels. In addition, mean HDL-cholesterol levels were 21.14 +- 5.82 mg/dl in males and 21.17 +- 6.02 mg/dl in females; total-cholesterol to HDL-cholesterol ratios were 5.47 +- 1.66 and 5.96 +- 2.81 in males and females respectively. About 60% patients showed low serum level of Zn and Cu. Hypothyroidism was detected in 30% patients and 23% patients had abnormal experimental values of all the study parameters. Conclusions: The majority of the patients had blood lipid levels (by the exception of HDL-cholesterol) within the normal range, and consequently the prevalence of lipid abnormalities was much lower as compared to the general population of the same age. Interestingly, the total-cholesterol to HDL-cholesterol ratio was high in our patients, and may underline the importance of this index for the prognosis of future cardiac events in these patients. The serum Zn and Cu levels were low in most of the patients which may cause some metabolic abnormalities in future. Most of the patients also showed hypothyroidism indicating the presence of endocrine complications. (author)

    Full Text Available Background: Polycystic ovary syndrome (PCOS is a common endocrine disorder associated with increased risk of cardiovascular disease. The purpose of this study was to investigate the ef-fects of omega-3 fatty acids on serum paraoxonase 1 activity and lipids ratios in polycystic ovary syndrome.Methods: This double-blind randomized controlled clinical trial was conducted on 64 PCOS pa-tients with 20-35 years old. Thirty two of the subjects had taken 4 g/day omega -3 fatty acids and 32 patients were given placebo for 8 weeks. Fasting blood samples, anthropometric measure-ments and dietary intakes were collected at the beginning and the end of the study. Serum total cholesterol, triglyceride, and HDL-C were measured using the enzymatic methods. LDL-C con-centration was calculated by the Friedewald formula and arylesterase activity of serum PON1 was measured. Data were analyzed using SPSS software.Results: Omega-3 fatty acids significantly decreased TC/HDL-C and LDL-C/HDL-C ratios (P = 0.009 for both and significantly increased serum PON1 activity (P = 0.048 compared with placebo. Changes in TG/HDL-C ratio were not statistically significant in omega-3 fatty acids group at the end of the study in comparison to placebo group. Reduction in TC/HDL-C, LDL-C/HDL-C and TG/HDL-C ratios and increase in serum PON1 activity were also significant in omega-3 fatty acids group at the end of the study compared with baseline values (P <0.001, P < 0.001, P = 0.004, and P = 0.001, respectively.Conclusion: Omega-3 fatty acids may decrease the risk for cardiovascular disease through the improvement in paraxonase-1 activity and reduction in some lipids ratio in PCOS women.

    Full Text Available Objective: In this study, it was aimed to evaluate the ef­fects of short-term intensive exercise on liver enzymes and serum lipid levels with kick boxing athletes. Methods: 23 voluntary athletes who were between the ages of 15-46 and who engaged in kick–boxing have tak­en place this study. Athletes were made to do 45 minutes of warming-up, breathing, and stretching and 50 minutes of technical and tactical practices and then they were made to do a training match, which is equal to a 2 min­utes 3 circuits (1 minute rest kick-box match. In venous blood samples which were taken from athletes before and after training, aspartate aminotransferase (AST, alanine aminotransferase (ALT, alkaline phosphatase (ALP and gamma glutamine transpeptidase (GGT, enzyme activity and total cholesterol, high-density lipoprotein-cholesterol (HDL-C, low density lipoprotein-cholesterol (LDL-C and triglycerides serum levels were analyzed via spectropho­tometric method in Beckman Coulter AU 5800 auto ana­lyzer. Body composition measurements of athletes were made with Tanita TBF 300 brand device, which works with bio-impedance analysis (BIA system. Results: As a result of our study, statistically increases in serum ALT, AST, ALP and GGT enzyme activities and in serum total cholesterol, HDL-C and LDL-C levels were detected following short-term intensive exercise, but no significant difference was observed in TG levels after in­tensive exercise. Conclusion: The blows to the abdomen during kickbox­ing sports competitions result in increased liver enzymes and increased serum lipids may occur to meet energy de­mand of the body during exercise.

    Full Text Available Introduction: Hyperlipidemia and diabetes are common risk factors for ischemic heart disease, which is the main cause of mortality in diabetic patients. Strict control of blood glucose and other risk factors in diabetics has led to prevention of complications. Garlic has received particular attention for control of blood glucose and decrease in blood lipid levels. At present, several studies have been carried out in order to prove advantages of garlic. Methods: In this study, effects of garsin (a derivative of garlic present in our country on serum lipids and blood glucose levels in diabetes mellitus type 2 patients was observed. Forty-five type 2 diabetics who had hyperlipidemia were selected. These patients were kept on treatment with 3 tablets of Garsin / day for 4 weeks. Serum lipids and blood glucose levels were measured prior to and at the end of treatment. Results: Relationship between sex and response to treatment in this study was meaningful, such that Gsarsin led to decrease in LDL-C and increase in HDL in females. Conclusion: Therefore, Garsin can be used as an adjunct to treatment in diabetes type 2 patients with hyperlipidemia.

    The purpose of the study was to evaluate the relationship between serum adiponectin and leptin concentrations and body composition, hematological indices and lipid profile parameters in adults. The study involved 95 volunteers (BMI from 23.3 to 53 kg/m²). Anthropometric parameters were measured: body weight and height, waist and hip circumference, waist-to-hip ratio, body fat mass (BMF), subcutaneous and visceral fat mass (SFM, VFM), lean body mass (LBM), skeletal muscle mass (SMM). In serum we determined adiponectin and leptin concentrations, extracellular hemoglobin, total bilirubin, as well as lipid metabolism (TCh, HDL-Ch, LDL-Ch, TG). Mean adipokine levels were significantly higher in women (p ≤ 0.01), adiponectin significantly negatively correlated with body height and weight, systolic blood pressure and absolute LBM and SMM values. The same relation was observed for erythroid system indicators and lipid indicators. A positive correlation was exceptionally found between adiponectin and HDL-Ch. LEP negatively correlated with some percentage rates (%LBM, %SMM). Only in women, we observed a positive correlation between LEP and body weight, BMI and WHR. Studies on ADPN and the ADPN/LEP ratio as a valuable complementary diagnostic element in the prediction and prevention of cardiovascular diseases need to be continued.

    Variation in serum cholesterol, free-fatty acids, and triglycerides is associated with cardiovascular disease (CVD) risk factors. There is great interest in characterizing the underlying genetic architecture of these risk factors, because they vary greatly within and among human populations and between the sexes. We present results of a genome-wide scan for quantitative trait loci (QTL) affecting serum cholesterol, free-fatty acids, and triglycerides in an F(16) advanced intercross line of LG/J and SM/J (Wustl:LG,SM-G16). Half of the population was fed a high-fat diet and half was fed a relatively low-fat diet. Context-dependent genetic (additive and dominance) and epigenetic (imprinting) effects were characterized by partitioning animals into sex, diet, and sex-by-diet cohorts. Here we examine genetic, environmental, and genetic-by-environmental interactions of QTL overlapping previously identified loci associated with CVD risk factors, and we add to the serum lipid QTL landscape by identifying new loci.

    Twenty one male patients aged 35 to 70 years, with coronary artery disease and dislipidemia refractory to dietary treatment, were assigned to three parallel groups of 7 individuals each that received a supplemental dose of 2, 4 and 6 g/day of omega-3 fatty acids during 60 days. After a 30 days wash-out period and 60 of supplementation, subjects were weighed, a dietary survey was performed, serum levels of total cholesterol and triglycerides, the lipid content of serum lipoproteins and the content of EPA+DHA in plasma phospholipids were measured. A dose dependent increase in EPA+DHA content of phospholipids and no changes in weight or nutrient intake were observed during the supplementation period. With the 6 g dose, a significant reduction in total cholesterol, with a reduction in VLDL and increase in LDL cholesterol and a decline in VLDL triglycerides was observed. With the 4 g dose a reduction in total cholesterol at the expense of VLDL and HDL cholesterol and a reduction in VLDL triglycerides but no changes in total triglycerides was observed. No changes in serum lipids were observed with 2 g dose. In patients with type IIA hyperlipidemia, a significant positive correlation was observed between DHA+EPA content of plasma phospholipids and LDL cholesterol, this correlation was not observed in patients with IIB or IV phenotypes. It is concluded that omega-3 fatty acids are ineffective as the only treatment for dislipidemias refractory to diet.

    Background It is still controversial whether or not the correlation between lipid abnormality and coronary heart disease (CHD) becomes weaker in the elderly, and whether patients above 80 years old still benefit from lipid management for the secondary prevention of CHD. The purpose of this study is to assess the correlation between hyperlipidemia and the risk of CHD events in the elderly, and to determine if it is appropriate to use lipid-lowering drugs in those aged above 80, as prescribed by the recommended guidelines for lipid management.Methods One thousand two hundred and eleven retirees, mainly males (92%), aged 70±9 years, were enrolled in this study. Lifestyle habits and medical history were recorded via questionnaires. During the period 1986 -2000, all subjects participated in an annual physical examination with a blood chemistry survey. The mean follow-up period was 11.2 years. Subjects with incidental illnesses, especially cardiovascular diseases, were diagnosed or treated promptly. Serum lipid parameters, including total cholesterol (TC), Iow and high-density lipoprotein cholesterol (LDL-C and HDL-C) and triglyceride (TG) levels were analyzed according to standardization of lipid and lipoprotein measurements. The association between lipid levels and the prevalence of acute myocardial infarction (AMI) or coronary death was analyzed statistically. Results Lipid abnormalities occurred in 2/3 of the 1211 subjects. The most common lipid disorder was high TC and high LDL-C, which was much more prevalent than high TG. Among the subjects, 51.6% had TC levels above 5.2 mmol/L. Mean TC and LDL-C reached peak levels in the 65-74 age group without significant decrease until ages over 90. The cumulative total number of deaths due to various causes was 397 in the 15-year follow-up period, with the mortality rate in the high lipid group slightly lower than that in the normal lipid group (30.6% vs 35. 3% ), although the difference was not significant (P=0

    This study investigated interactions between dietary fat intake and IL-6 polymorphisms on obesity and serum lipids in black and white South African (SA) women. Normal-weight and obese, black and white women underwent measurements of body composition, serum lipids and dietary fat intake, and were genotyped for the IL-6 -174 G>C, IVS3 +281 G>T and IVS4 +869 A>G polymorphisms. In black women the IVS4 +869 G allele was associated with greater adiposity, and with increasing dietary fat intake adiposity increased in the IVS3 +281 GT+GG and IVS4 +869 AA or AG genotypes. In white women, with increasing omega-3 (n-3) intake and decreasing n-6:n-3 ratio, body mass index (BMI) decreased in those with the -174 C allele, IVS3 +281 T allele and IVS4 +869 AG genotype. In the white women, those with the IVS3 +281 T allele had lower triglycerides. Further, with increasing n-3 polyunsaturated fatty acid (PUFA); triglyceride and total cholesterol:high-density lipoprotein cholesterol (T-C:HDL-C) ratio decreased in those with the -174 C allele. In black women, with increasing total fat intake, triglycerides and T-C:HDL-C ratio increased in those with the IVS4 +869 G allele. This study is the first to show that dietary fat intake modulates the relationship between the IL-6 -174 G>C, IVS3 +281 G>T and IVS4 +869 A>G polymorphisms on obesity and serum lipids in black and white SA women.

    Full Text Available Abstract Background During the past two decades, the hypothesis of fetal origins of adult disease has received considerable attention. However, critique has also been raised regarding the failure to take the explanatory role of accumulation of other exposures into consideration, despite the wealth of evidence that social circumstances during the life course impact on health in adulthood. The aim of the present prospective cohort study was to examine the contributions of birth weight and life course exposures (cumulative socioeconomic disadvantage and adversity to dyslipidemia and serum lipids in mid-adulthood. Methods A cohort (effective n = 824, 77% was prospectively examined with respect to self-reported socioeconomic status as well as stressors (e.g., financial strain, low decision latitude, separation, death or illness of a close one, unemployment at the ages of 16, 21, 30 and 43 years; summarized in cumulative socioeconomic disadvantage and cumulative adversity. Information on birth weight was collected from birth records. Participants were assessed for serum lipids (total cholesterol, low- and high-density lipoprotein cholesterol and triglycerides, apolipoproteins (A1 and B and height and weight (for the calculation of body mass index, BMI at age 43. Current health behavior (alcohol consumption, smoking and snuff use was reported at age 43. Results Cumulative life course exposures were related to several outcomes; mainly explained by cumulative socioeconomic disadvantage in the total sample (independently of current health behaviors but attenuated by current BMI and also by cumulative adversity in women (partly explained by current health behavior but not by BMI. Birth weight was related only to triglycerides in women, independently of life course exposures, health behaviors and BMI. No significant association of either exposure was observed in men. Conclusions Social circumstances during the life course seem to be of greater importance

    An 8-week feeding trial was conducted to detect the optimal dietary protein and energy, as well as the effects of protein to energy ratio on growth, for the rare minnow ( Gobiocypris rarus), which are critical to nutrition standardization for model fish. Twenty-four diets were formulated to contain three gross energy (10, 12.5, 15 kJ/g), four protein (20%, 25%, 30%, 35%), and two lipid levels (3%, 6%). The results showed that optimal dietary E/P was 41.7-50 kJ/g for maximum growth in juvenile rare minnows at 6% dietary crude lipid. At 3% dietary lipid, specific growth rate (SGR) increased markedly when E/P decreased from 62.5 kJ/g to 35.7 kJ/g and gross energy was 12.5 kJ/g, and from 75 kJ/g to 42.9 kJ/g when gross energy was 15.0 kJ/g. The optimal gross energy was estimated at 12.5 kJ/g and excess energy decreased food intake and growth. Dietary lipid exhibited an apparent protein-sparing effect. Optimal protein decreased from 35% to 25%-30% with an increase in dietary lipid from 3% to 6% without adversely effecting growth. Dietary lipid level affects the optimal dietary E/P ratio. In conclusion, recommended dietary protein and energy for rare minnow are 20%-35% and 10-12.5 kJ/g, respectively.

  14. Lipid synthesis and secretion in HepG2 cells is not affected by ACTH

    Full Text Available Abstract Apolipoprotein B (apoB containing lipoproteins, i.e. VLDL, LDL and Lp(a, are consequently lowered by ACTH treatment in humans. This is also seen as reduced plasma apoB by 20-30% and total cholesterol by 30-40%, mostly accounted for by a decrease in LDL-cholesterol. Studies in hepatic cell line (HepG2 cells showed that apoB mRNA expression is reduced in response to ACTH incubation and is followed by a reduced apoB secretion, which may hypothesize that ACTH lowering apoB containing lipoproteins in humans may be mediated by the inhibition of hepatic apoB synthesis. This was recently confirmed in vivo in a human postprandial study, where ACTH reduced transient apoB48 elevation from the small intestine, however, the exogenic lipid turnover seemed unimpaired. In the present study we investigated if lipid synthesis and/or secretion in HepG2 cells were also affected by pharmacological levels of ACTH to accompany the reduced apoB output. HepG2 cells were incubated with radiolabelled precursors ([14C]acetate and [3H]glycerol either before or during ACTH stimuli. Cellular and secreted lipids were extracted with chloroform:methanol and separated by the thin layer chromatography (TLC, and [14C]labelled cholesterol and cholesteryl ester and [3H]labelled triglycerides and phospholipids were quantitated by the liquid scintillation counting. It demonstrated that ACTH administration did not result in any significant change in neither synthesis nor secretion of the studied lipids, this regardless of presence or absence of oleic acid, which is known to stabilize apoB and enhance apoB production. The present study suggests that ACTH lowers plasma lipids in humans mainly mediated by the inhibition of apoB synthesis and did not via the reduced lipid synthesis.

    Full Text Available Background/Aim. Some oligoelements are now investigated as possibly having a role in atherosclerosis. The aim of this study was to compare the concentrations of copper and zinc in the serum and carotid plaque and parameters of lipid metabolism in patients with different morphology of carotid atherosclerotic plaque. Methods. Carotid endarterectomy due to the significant atherosclerotic stenosis was performed in 91 patients (mean age 64 ± 7. The control group consisted of 27 patients (mean age 58 ± 9, without carotid atherosclerosis. Atheroscletoric plaques were divided into four morphological groups, according to ultrasonic and intraoperative characteristics. Copper and zinc concentrations in the plaque, carotid artery and serum were measured by atomic absorption spectrophotometry. Results. Serum copper concentrations were statistically significantly higher in the patients with hemorrhagic in comparison to those with calcified plaque (1.2 ± 0.9 μmol/L vs 0.7 ± 0.2 μmol/L, respectively; p = 0.021. Zinc concentrations were statistically significantly lower in plaques of the patients with fibrolipid in comparison to those with calcified plaques (22.1 ± 16.3 μg/g vs 38.4 ± 25.8 μg/g, respectively; p = 0.024. A negative significant correlation was found for zinc and triglycerides in the serum in all the patients (r = -0.52, p = 0.025. In the control group we also demonstrated a positive significant correlation for low-density lipoprotein cholesterol and copper in the serum (r = 0.54, p = 0.04. Conclusion. The data obtained in the current study are consistent with the hypothesis that high copper and lower zinc levels may contribute to atherosclerosis and its sequelae as factors in a multifactorial disease. Further studies are necessary in order to conclude whether high concentration of copper and zinc in the serum could be risk factors for atherosclesrosis.

    This study aims to investigate the effects of the plant growth regulators (PGRs) (2,3,5-triiodobenzoic acid (TIBA), Naphthaleneacetic acid (NAA), and 2,4-dichlorofenoxyacetic acid (2,4-D)) on serum marker enzymes (aspartate aminotransferase (AST), alanin aminotransferase (ALT), creatine phosphokinase (CPK), and lactate dehydrogenase (LDH)), antioxidant defense systems (reduced glutathione (GSH), glutathione reductase (GR), superoxide dismutase (SOD), glutathione-S-transferase (GST), and catalase (CAT)), and lipid peroxidation content (malondialdehyde = MDA) in various tissues of rats. 50 and 100 ppm of PGRs as drinking water were administered orally to rats (Sprague-Dawley albino) ad libitum for 25 days continuously. The PGRs treatment caused different effects on the serum marker enzymes, antioxidant defense systems, and the MDA content in experimented rats compared to controls. Results showed that TIBA caused a significant decrease in serum AST activity with both the dosage whereas serum CPK was significantly increased with 100 ppm dosage of TIBA. Meanwhile, serum AST, CPK, and LDH activities were significantly increased with both dosage of NAA and 2,4-D. The lipid peroxidation end-product MDA significantly increased in the all tissues treated with both dosages of PGRs without any change in the brain and erythrocyte of rats treated with both the dosages of 2,4-D. The GSH depletion in the kidney and brain tissues of rats treated with both dosages of PGRs was found to be significant. Furthermore, the GSH depletion in the erythrocyte of rats treated with both dosages of PGRs except 50 ppm dosage of 2,4-D was significant too. Also, the GSH level in the liver was significantly depleted with 50 ppm of 2,4-D and NAA, whereas the GSH depletion in the same tissue did not significantly change with the treatment. The activity of antioxidant enzymes was also seriously affected by PGRs; SOD significantly decreased in the liver, heart, kidney, and brain of rats treated with

    Full Text Available Abstract Background Acyl-CoA:cholesterol acyltransferase (ACAT is a key enzyme in cellular cholesterol homeostasis and in atherosclerosis. The cellular cholesterol efflux correlated with serum high-density lipoprotein cholesterol (HDL-C concentrations has shown to be impaired in hyperlipidemic mice. The present study was carried out to clarify the association of ACAT-1 rs1044925 single nucleotide polymorphism (SNP and serum lipid levels in the hyperlipidemic subjects. Methods A total of 821 unrelated subjects (hyperlipidemia, 476; normolipidemia, 345 aged 15-80 were included in the study. Genotyping of the ACAT-1 rs1044925 SNP was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Results There was no significant difference in the genotypic and allelic frequencies of ACAT-1 rs1044925 SNP between the normolipidemic and hyperlipidemic subjects. The levels of total cholesterol (TC, HDL-C and apolipoprotein (Apo AI in hyperlipidemic subjects were different between the AA and AC/CC genotypes in male but not in female (P Conclusions The present study shows that the C allele carriers of ACAT-1 rs1044925 SNP in male hyperlipidemic subjects had higher serum TC, HDL-C and ApoAI levels than the C allele noncarriers. There is a sex (male-specific association of ACAT-1 rs1044925 SNP and serum HDL-C and ApoAI levels in the hypercholesterolemic subjects.

    Full Text Available Abstract Abstract Hyperlipidemia and increased degree of oxidative stress are among the important risk factors for Atherosclerosis in renal transplant recipients (RTR. The Medical treatment of hyperlipidemia in RTR because of drugs side effects has been problematic, therefore alternative methods such as using of Garlic as an effective material in cholesterol lowering and inhibition of LDL Oxidation has been noted. For evaluation of garlic effect on RTR, 50 renal transplant patients with stable renal function were selected and divided into 2 groups. They took one clove of garlic (1 gr by chewing or swallowing for two months, after one month wash-out period, they took garlic by the other route. Results indicated that although lipid profile, BUN, Cr, serum levels of cyclosporine and diastolic blood pressure did not change, Systolic blood pressure decreased from138.2 to 132.8 mmHg (p=0.001 and Malondialdehyde (MDA decreased from 2.4 to1.7 nmol/ml (p=0.009 by swallowing route, Cholesterol decreased from 205.1 to 195.3 mg/dl (p=0.03, triglyceride decreased from 195.7 to 174.8 mg/dl (p=0.008, MDA decreased from 2.5 to 1.6 nmol/ml (p=0.001, systolic blood pressure decreased from 137.5 to 129.8 mmHg (p=0.001, diastolic blood pressure decreased from 84.6 to 77.6 mmHg (p=0.001 and Cr decreased from 1.51 to 1.44 mg/dl (p=0.03 by chewing route too. However HDL, LDL and cyclosporine serum levels had no significant differences by both of swallowing and chewing routes. We conclude that undamaged garlic (swallowed had no lowering effect on lipid level of serum. But Crushed garlic (chewed reduces cholesterol, triglyceride, MDA and blood pressure. Additionally creatinine reduced without notable decrease in cyclosporine serum levels may be due to cyclosporine nephrotoxicity ameliorating effect of garlic.

    ɛ-Polylysine (EPL) is used as a natural preservative in food. However, few studies have been conducted to assess the beneficial functions of dietary EPL. The purpose of this study was to elucidate the mechanism underlying the inhibition of neutral and acidic sterol absorption and hepatic enzyme activity-related fatty acid biosynthesis following EPL intake. EPL digest prepared using an in vitro digestion model had lower lipase activity and micellar lipid solubility and higher bile acid binding capacity than casein digest. Male Wistar rats were fed an AIN-93G diet containing 1% (wt/wt) EPL or l-lysine. After 4 weeks of feeding these diets, the marked decrease in serum and liver triacylglycerol contents by the EPL diet was partly attributed to increased fecal fatty acid excretion. The activities of hepatic acetyl-coenzyme A carboxylase and glucose-6-phosphate dehydrogenase, which are key enzymes of fatty acid biosynthesis, were enhanced in rats fed EPL diet. The increased fatty acid biosynthesis activity due to dietary EPL may be prevented by the enhancement of fecal fatty acid excretion. The hypocholesterolemic effect of EPL was mediated by increased fecal neutral and acidic sterol excretions due to the EPL digest suppressing micellar lipid solubility and high bile acid binding capacity. These results show that dietary EPL has beneficial effects that could help prevent lifestyle-related diseases such as hyperlipidemia and atherosclerosis. PMID:25866749

    Full Text Available Background/Aims: An increasing body of evidence demonstrates that L-carnitine plays a pivotal role in lipid metabolism of hemodialysis (HD patients. However, there are still some reservations about its benefits. Therefore, we performed a meta-analysis to assess the effects of L-carnitine supplementation on lipid profile in HD patients. Methods: Literature search was performed to identify the relevant randomized controlled trials that investigated the effects of L-carnitine on the lipid profile of subjects. Two independent authors used an Excel file to extract data and assess trials quality. The primary effect measure was the difference in means of the final lipid measurements between the intervention and control groups. The meta-analysis was performed with the fixed-effects model or random-effects model according to heterogeneity. Results: Twelve studies with a total of 391 patients met the inclusion criteria. The use of L-carnitine was not associated with a reduction in the total cholesterol (SMD, -0.11; 95% CI, -0.31 to 0.09, HDL-cholesterol (SMD, 0.01; 95% CI, -0.36 to 0.39, VLDL-cholesterol (SMD, 0.54; 95% CI, -0.06 to 1.14, and the serum triglycerides (SMD, -0.12; 95% CI, -0.36 to 0.12. However, L-carnitine can significantly decrease the LDL-cholesterol (SMD, -0.29; 95% CI, -0.53 to -0.06 in HD patients. In a subgroup meta-analysis, a significant LDL-cholesterol-lowering effect of L-carnitine supplementation was observed in intravenous application group, and patients with longer interventional duration and renal diseases. Conclusion: The limited evidence suggests that there was no effect of L-carnitine on serum total cholesterol, HDL-cholesterol, VLDL-cholesterol and serum triglycerides. By contrast, this meta-analysis suggests a promising effect of L-carnitine on LDL-cholesterol. Further large-scale, well-designed randomized controlled trials are urgently needed

    We prospectively measured lipid peroxidation following reperfusion during 44 renal allograft transplant operations. Twenty-four (55%) recipients were taking nifedipine pre- and then postoperatively, and 20 (45%) were not. There were no differences between the groups in terms of recipient or donor status. Plasma malondialdehyde (MDA), mean 2.2 (0.2) mumol/L (SEM) vs. 1.73 (0.1) was greater in the group not prescribed nifedipine, p nifedipine group to 0.38 (0.02) at 30 min after reperfusion and 0.38 (0.03) at 60 min, p nifedipine and no-nifedipine groups, respectively. There was no difference in postoperative renal function between the groups. This study suggests that the oral administration of nifedipine may not prevent the production of lipid peroxides, as measured by changes in plasma malondialdehyde, following renal allograft reperfusion and that it does not affect renal function in the early postoperative period.

    The aim of this study was to investigate the changes of serum mitochondrial uncoupling protein 1 (UCP1) and leptin levels as well as of lipid and lipoprotein profiles in mares during the peripartum period. Ten pregnant mares (group A) were monitored from 15 ± 3 days of pregnancy until 15 days after foaling, and 10 nonpregnant nonlactating mares constituted the control (group B). In group A, blood sampling was performed on Days 15 ± 3 and 7 ± 3 before foaling, on the day of foaling, and on Days 7 and 15 after foaling. In group B, blood sampling was performed on the same days as in group A. Serum levels were determined for UCP1, leptin, total lipids, phospholipids, triglycerides, total cholesterol (Total-Chol), high-density lipoproteins, low-density lipoproteins (LDLs), and very low-density lipoproteins (VLDLs). Two-way repeated-measures ANOVA was applied to evaluate the effects of peripartum period and group membership. All studied parameters except phospholipid levels (P > 0.05) showed significant changes in group A over the peripartum period (P leptin and total lipids, triglycerides, VLDLs, Total-Chol, and LDLs. These changes observed in mares during the peripartum period could represent a response to hormonal and metabolic adaptations occurring during specific physiological conditions such as late pregnancy and early postpartum. These changes should compensate for the energy loss occurring during these particular life phases and ensure a good body condition to protect mares against negative energy balance. PMID:27165993

    Full Text Available Tryptophan (Trp is present in the serum, partly bound to albumine and in the free form. The unbound portion of circulating tryptophan has the property of crossing the hematoencephalic barrier and being converted within the brain into serotonin (5-HT through the enzymatic processes of hydroxylation and decarboxylation. The serotoninergic system plays an important role in neuroendocrine control of reproductive hormone secretion, and in particular, it may influence GnRH pulsatility, a function essential for reproductive processes. In this study, we analysed serum levels of tryptophan, serotonin and 5-hydroxytryptophan (5-HTP in women with three different forms of amenorrhea: 16 patients were diagnosed with anorexia nervosa, 60 patients with functional hypothalamic amenorrhea, and 14 patients with hyperprolactinemia. Data were compared with those of a group of 25 healthy women. Serum Trp levels were significantly (P ≤ 0.05 lower in the anorexic (11.64 ± 0.53 µg/ml, mean ± S.E. than in the control (12.98 ± 0.37 µg/ml groups. In addition, in the anorexic group a statistical dispersion of Trp values was shown indicating a bimodal data distribution suggesting the existence of two different subgroups of patients. Regarding 5-HTP, an increase of its serum level was observed in all the groups with amenorrhea with the highest value in hyperprolactinemic patients. On the contrary, no statistical differences in serum 5-HT levels among the four analyzed groups were observed. This study shows that women affected by various forms of amenorrhea present an altered metabolism of tryptophan via serotonin and, in particular, markedly high differences are observed between the two subgroups of anorexic patients.

    Full Text Available Dyslipidemia is a significant morbidity associated with diabetes and cardiovascular disorders. The present study was undertaken to assess the lipid profile of type 2 diabetic and age-gender matched healthy subjects and its association, if any, with fasting plasma glucose. Clinically diagnosed diabetic subjects were recruited for the study. The fasting plasma glucose and lipid profiles were analyzed for 99 diabetic and 101 healthy volunteers. The blood samples were analyzed for fasting plasma glucose, total cholesterol, triglycerides, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol and very low density lipoprotein-cholesterol. Correlation analysis of lipid profile with fasting plasma glucose and calculation of risk ratio was done. The levels of high density lipoprotein-cholesterol and low density lipoprotein-cholesterol were found to be significantly low in diabetics and subjects with lower low density lipoprotein-cholesterol were on statins. Inspite of lower lipid values, the risk ratio for diabetics was significantly higher. The correlation analysis indicated significant difference in relationship between fasting plasma glucose, lipid parameters and risk ratios in the two groups. Diabetics with lower high density lipoprotein-cholesterol and higher total cholesterol present with a higher risk ratio pointing to need of non-statin high density lipoprotein-raising medications decreasing their predisposition to cardiovascular disorders. The study highlights the altered pattern of correlation of lipid profile with fasting plasma glucose in diabetics and their increased risk of cardiovascular disorders. The dyslipidemia in the form of triglyceridemia and significantly low high density lipoprotein-cholesterol in diabetics point towards the need of non-statin high density lipoprotein-raising medications.

    Full Text Available S100B, established as prevalent protein of the central nervous system, is a peripheral biomarker for blood-brain barrier disruption and often also a marker of brain injury. However, reports of extracranial sources of S100B, especially from adipose tissue, may confound its interpretation in the clinical setting. The objective of this study was to characterize the tissue specificity of S100B and assess how extracranial sources of S100B affect serum levels. The extracranial sources of S100B were determined by analyzing nine different types of human tissues by ELISA and Western blot. In addition, brain and adipose tissue were further analyzed by mass spectrometry. A study of 200 subjects was undertaken to determine the relationship between body mass index (BMI and S100B serum levels. We also measured the levels of S100B homo- and heterodimers in serum quantitatively after blood-brain barrier disruption. Analysis of human tissues by ELISA and Western blot revealed variable levels of S100B expression. By ELISA, brain tissue expressed the highest S100B levels. Similarly, Western blot measurements revealed that brain tissue expressed high levels of S100B but comparable levels were found in skeletal muscle. Mass spectrometry of brain and adipose tissue confirmed the presence of S100B but also revealed the presence of S100A1. The analysis of 200 subjects revealed no statistically significant relationship between BMI and S100B levels. The main species of S100B released from the brain was the B-B homodimer. Our results show that extracranial sources of S100B do not affect serum levels. Thus, the diagnostic value of S100B and its negative predictive value in neurological diseases in intact subjects (without traumatic brain or bodily injury from accident or surgery are not compromised in the clinical setting.

    Full Text Available Acute coronary syndrome is one of the leading causes of morbidity and mortality worldwide , hyperlipidemias being a major predisposing factor. Cardiac Troponin T (cTnT is one of the most sensitive and specific biomarkers of myocardial injury. The aim of the study was to evaluate the relationship among TnT levels and lipid profiles of different age groups of patients with ACS , and to determine if any the association of age with lipid profile and TnT levels. The lipid profiles and TnT levels were de termined in 464 patients with acute coronary syndrome. Depending upon age , the patients were divided into groups 1 , 2 and 3 (49 ≤ , 50 - 69 and ≤ 70 years respectively. Increasing age was found to be associated with fall in mean levels of total cholesterol , LD L , triglycerides and TnT. Our study suggested that among patients with ACS , there exists a relation between age , lipid components and TnT levels. TnT is known to be an independent predictor of the outcome of myocardial ischemia. Further studies are therefo re required to ascertain the validity of TnT as a prognostic cardiac biomarker among the elderly

The associated changes in serum antioxidants and lipid peroxidation were also assessed along with lipid profile and anthropometric measurements in both groups of subjects under study.Results:Dietary intake of vitamins was assessed by 131 food frequency questionnaire items B2 and ascorbic acid compared to normotensive controls. Anthropometric variables in the hypertensive showed significant differences in weight, body mass index, waist circumference, hip circumference, waist-hip ratio and mid-arm circumference. The total cholesterol, low-density lipoprotein cholesterol, triglyceride were significantly higher (P<0.001) in hypertensive except high-density lipoprotein cholesterol which was significantly higher (P<0.001) in normotensive. The serum endogenous antioxidants and enzyme antioxidants were significantly decreased in hypertensive except serum albumin levels compared to normotensive along with concomitant increase in serum lipoprotein (a) malondialdehyde and conjugated diene levels. Dietary vitamins intake was higher in hypertensive participants excepting for vitamin Conclusions: Based on the observations, our study concludes that hypertension is caused due to interplay of several confounding factors namely anthropometry, lipid profile, depletion of endogenous antioxidants and rise in oxidative stress.

    Full Text Available Ghee is also known as clarified butter, utilized for thousands of years in Ayurveda as a therapeutic agent. Ghee which is known as “Gritha” in Ayurveda, described as the best among lipid media due to its quality of inheriting and enhancing the drug potency. Even though ghee is an animal fat, earlier studies have shown that larger doses given for cleansing purpose did not increase the level of Low Density Lipoprotein (LDL. Instead increased High Density Lipoprotein (HDL or some time did not alter lipid profile at all. Earlier studies in rats, which were fed up to 10% dietary ghee showed dose dependent decrease in cholesterol and other lipid profiles. There are two methods in preparation of butter. One is from milk cream, clarified butter and the other from curds, cultured butter. Butter will be further processed to convert it into ghee. None of the earlier studies have shown, which type of ghee is better and compared their effects on lipid profiles. So, our objective of the study was to know the effects of 5% and 10% milk cream ghee (Ghee from clarified Butter and curd ghee (Ghee made out of Cultured Butter supplementation on lipid profile in Wistar rats. So we supplied 5% and 10% dietary ghee in a nutritionally balanced diet to 8 weeks old male rats for 12 weeks and estimated Total cholesterol, HDL, LDL, Very Low Density Lipoprotein (VLDL and Triglycerides (TGL levels after 12 weeks. These results indicate that 5% and 10% of cream ghee and 10% curds ghee did increase body weight after 12 weeks of consumption and 5% curds ghee was found not to increase the body weight; 5% Curd Ghee has shown to lower total cholesterol, LDL, VLDL, triglycerides levels and cholesterol ratio more than other groups in our experimental model. HDL levels were increased in all the groups, which was not statistically significant in 5% cream and 5% curd ghee groups.

Methods Animals were exposed to a single stimulation (2 h of ELF-EMF (60 Hz, 2.4 mT or sham-stimulated and thereafter sacrificed at different times (24, 48 or 96 h after beginning the exposure. Results Blood lipids showed, at 48 h stimulated animals, a significant increase of cholesterol associated to high density lipoproteins (HDL-C than those observed at any other studied time. Free fatty acid serum presented at 24 h significant increases in comparison with control group. The other serum lipids, triacylglycerols and total cholesterol did not show differences between groups, at any time evaluated. No statistical differences were shown on total lipids of the liver but total cholesterol was elevated at 24 h with a significant decrease at 96 h (p = 0.026. The ELF-EMF stimulation increased the liver content of lipoperoxides at 24 h. Conclusion Single exposures to ELF-EMF increases the serum values of HDL-C, the liver content of lipoperoxides and decreases total cholesterol of the liver. The mechanisms for the effects of ELF-EMF on lipid metabolism are not well understand yet, but could be associated to the nitric oxide synthase EMF-stimulation.

    Prebiotic fibres have been proposed to promote weight loss and lower serum cholesterol; however, the mechanisms are not fully understood. The aim of the present research was to identify possible mechanisms through which prebiotic fibres improve serum lipids. Lean and obese JCR:La-cp rats aged 8 weeks consumed one of three diets supplemented with 0, 10 or 20 % prebiotic fibre for 10 weeks. Rats were anaesthetised and a fasting blood sample was taken for lipid analysis. Real-time PCR was used t...

    The effect of Shengmaisan (SMS) on 62 acute viral myocarditis patients and its peroxidation damage was studied. The results revealed that the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in blood were decreased and the content of malondialdehyde (MDA) in plasma was increased in acute viral myocarditis patients in comparison with the healthy controls (P SMS group and placebo group. After treatment, both SOD and GSH-Px activities were increased and the level of MDA decreased (P SMS group, while those in placebo group were not changed (P < 0.05). The results suggested that the myocardial damage of viral myocarditis is closely related with lipid peroxidation SMS acts as an effective free radical scavenger and anti-lipid peroxidation drug. SMS could prevent the damage of myocardia and might be taken as one of the effective therapeutic methods in treatment of acute viral myocarditis. PMID:9208534

    Gallium is an iron mimetic which has recently been repurposed as an antibacterial agent due to its capability to disrupt bacterial iron metabolism. In this study, the antibacterial activity of gallium nitrate [Ga(NO3)3] was investigated in complement-free human serum (HS) on 55 Pseudomonas aeruginosa clinical isolates from cystic fibrosis and non-cystic fibrosis patients. The susceptibility of P. aeruginosa to Ga(NO3)3 in HS was dependent on the bacterial ability to acquire iron from serum binding proteins (i.e., transferrin). The extent of serum protein degradation correlated well with P. aeruginosa growth in HS, while pyoverdine production did not. However, pyoverdine-deficient P. aeruginosa strains were unable to grow in HS and overcome iron restriction, albeit capable of releasing proteases. Predigestion of HS with proteinase K promoted the growth of all strains, irrespective of their ability to produce proteases and/or pyoverdine. The MICs of Ga(NO3)3 were higher in HS than in an iron-poor Casamino Acids medium, where proteolysis does not affect iron availability. Coherently, strains displaying high proteolytic activity were less susceptible to Ga(NO3)3 in HS. Our data support a model in which both pyoverdine and proteases affect the response of P. aeruginosa to Ga(NO3)3 in HS. The relatively high Ga(NO3)3 concentration required to inhibit the growth of highly proteolytic P. aeruginosa isolates in HS poses a limitation to the potential of Ga(NO3)3 in the treatment of P. aeruginosa bloodstream infections.

    Full Text Available The purpose of this study was to examine an influence of a mixed aerobic and strength training program (MAST on anthropometry, serum lipid levels, physical performance, and functional fitness in obese postmenopausal women. The MAST sessions were held three times per week, and the exercise program lasted for 10 weeks. The exercise group demonstrated a statistically significant improvement in maximal oxygen uptake, a waist/hip ratio, and strength of the upper and lower body. An increase in LDL-C levels was observed in the control group. A 10-week MAST program encompassing Nordic-walking as an aerobic component, and strength exercises, induces positive changes in functional fitness, HDL-C, LDL-C and a waist/hip ratio in obese postmenopausal women. The observed changes implicate an increase in a health-related quality of life among the women administered to the physical exercise program

    Full Text Available Abstract Background Beta-thalassaemia major (b-TM has been defined as a combination of chronic hemolytic anemia, iron storage disease and myocarditis, and it has been associated with premature death especially due to heart failure. To the best of our knowledge the status of blood lipids in these patients has rarely been investigated. Thus, we assessed the levels of lipids and lipoproteins in a sample of cardiovascular disease free adult men and women with b-TM. Methods During 2003 we enrolled 192 consecutive patients with b-TM that visited our Institution for routine examinations. The Institution is considered the major reference center for b-TM in Greece. Of the 192 patients, 88 were men (25 ± 6 years old and 104 women (26 ± 6 years old. Fasting blood lipid levels were measured in all participants. Results Data analysis revealed that 4% of men and 2% of women had total serum cholesterol levels > 200 mg/dl, and 11% of men and 17% of women had triglyceride levels > 150 mg/dl. In addition, mean HDL cholesterol levels were 32 ± 11 mg/dl in men and 38 ± 10 mg/dl in women, lipoprotein-a levels were 8.3 ± 9 mg/dl in men and 8.8 ± 9 mg/dl in women, apolipoprotein-A1 levels were 111 ± 17 mg/dl in men and 123 ± 29 mg/dl in women, and apolipoprotein-B levels were 60 ± 20 mg/dl in men and 59 ± 14 mg/dl in women. Total-to-HDL cholesterol ratios were 3.7 ± 1.2 and 3.8 ± 1.5 in men and women, respectively. Conclusions The majority of the patients had blood lipid levels (by the exception of HDL-cholesterol within the normal range, and consequently the prevalence of lipid and lipoprotein abnormalities was much lower as compared to the general population of the same age. Interestingly, is that the total – to HDL cholesterol ratio was high in our patients, and may underline the importance of this index for the prognosis of future cardiac events in these patients.

    Full Text Available Neutering females may be associated to weight gain in dogs. In order to diagnose possible alterations, such as diabetes and hyperlipidemias, laboratory assessment of carbohydrate and lipid metabolism is important. The aim of this study was to verify glycemia and serum lipid profile in non-spayed and spayed female dogs, and associate these results with the body condition score. Thirty-two spayed (n=16 and non-spayed (n=16 female dogs had their blood collected for biochemical analysis, and were classified as to their body condition score (BCS. Nine had normal BCS, 10 were overweight, and 13 were obese. Little difference was observed among spayed and non-spayed dogs. Glycemia of spayed canine females is higher than that of non-spayed dogs, regardless of the body condition score. Likewise, total cholesterol levels are higher in non-spayed females. The HDL is higher in non-spayed obese dogs than in spayed dogs with the same body condition, this parameter did not differ in other weight groups. Contrary to what happens in post-menopausal women, spaying dogs does not seem to have such a strong effect on the metabolic parameters assessed. This study revealed unique results, where neither spaying nor weight group had a strong association with metabolic alterations.

    Background and objectives Hyperlipidemia is common in patients with CKD. The objective of this study was to evaluate whether measures of plasma lipids and lipoproteins predict progression of kidney disease in patients with CKD. Design, setting, participants, & measurements Prospective cohort study in adults (n=3939) with CKD aged 21–74 years recruited between 2003 and 2008 and followed for a median of 4.1 years. At baseline, total cholesterol, triglycerides, very-low-density lipoprotein cholesterol (VLDL-C), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), apoA-I , apoB, and lipoprotein(a) [Lp(a)] were measured. The outcomes were composite end point of ESRD or 50% decline in eGFR from baseline (rate of change of GFR). Results Mean age of the study population was 58.2 years, and the mean GFR was 44.9 ml/min per 1.73 m2; 48% of patients had diabetes. None of the lipid or lipoprotein measures was independently associated with risk of the composite end point or rate of change in GFR. However, there were significant (P=0.01) interactions by level of proteinuria. In participants with proteinuria0.2 g/d, neither LDL-C (HR, 0.98; 95% CI, 0.98 to 1.05) nor total cholesterol levels were associated with renal outcomes. Treatment with statins was reported in 55% of patients and was differential across lipid categories. Conclusions In this large cohort of patients with CKD, total cholesterol, triglycerides, VLDL-C, LDL-C, HDL-C, apoA-I, apoB, and Lp(a) were not independently associated with progression of kidney disease. There was an inverse relationship between LDL-C and total cholesterol levels and kidney disease outcomes in patients with low levels of proteinuria. PMID:24832097

    Full Text Available Background Menopause, a natural phenomenon, is defined by the fall of ovarian hormones mainly estrogens causing major problems such as insulin resistance. Fenugreek (Trigonella foenum-graecum is known to have some useful properties such as insulin sensitizing effect. Apelin is an adipokine, which has several roles such as regulation of insulin secretion. Objectives The objective of the present study was to evaluate the effect of fenugreek seed and 17-β estradiol on serum Apelin along with glucose, lipids and insulin in ovariectomized rats. Materials and Methods Forty-nine adult female Wistar rats were randomly divided to seven groups: normal control, ovariectomized control, ovariectomized treated with ethanolic and hexanic extract of fenugreek seed (50 and 150 mg/kg/daily for each, and ovariectomized treated with 17-β estradiol (10 µg/kg/daily for 42 days. Serum Apelin, glucose, lipids and insulin were measured. Results Serum Apelin, glucose, lipids and insulin significantly increased in ovariectomized controls in comparison with normal controls (P < 0.05. Serum glucose, lipids and insulin in ovariectomized rats treated with fenugreek seed extract and 17-β estradiol were remarkably lower than ovariectomized controls (P < 0.05. Furthermore, 17-β estradiol caused a significant decrease (P < 0.05 in serum Apelin in ovariectomized rats. Conclusions It appears that fenugreek seed might be effective against hyperglycemia, hyperlipidemia and insulin resistance in ovariectomized rats without impact on serum Apelin. Furthermore, 17-β estradiol could have similar effects along with possible inhibitory effects on serum Apelin. The complicated role of Apelin in menopause needs to be further explored.

    Lipid nanocapsules (LNCs) are semi-rigid spherical capsules with a triglyceride core that present a promising formulation option for the pulmonary delivery of drugs with poor aqueous solubility. Whilst the biodistribution of LNCs of different size has been studied following intravenous administration, the fate of LNCs following pulmonary delivery has not been reported. We investigated quantitatively whether lung inflammation affects the clearance of 50nm lipid nanocapsules, or is exacerbated by their pulmonary administration. Studies were conducted in mice with lipopolysaccharide-induced lung inflammation compared to healthy controls. Particle deposition and nanocapsule clearance kinetics were measured by single photon emission computed tomography/computed tomography (SPECT/CT) imaging over 48 h. A significantly lower lung dose of (111)In-LNC50 was achieved in the lipopolysaccharide (LPS)-treated animals compared with healthy controls (p<0.001). When normalised to the delivered lung dose, the clearance kinetics of (111)In-LNC50 from the lungs fit a first order model with an elimination half-life of 10.5±0.9h (R(2)=0.995) and 10.6±0.3h (R(2)=1.000) for healthy and inflamed lungs respectively (n=3). In contrast, (111)In-diethylene triamine pentaacetic acid (DTPA), a small hydrophilic molecule, was cleared rapidly from the lungs with the majority of the dose absorbed within 20min of administration. Biodistribution to lungs, stomach-intestine, liver, trachea-throat and blood at the end of the imaging period was unaltered by lung inflammation. This study demonstrated that lung clearance and whole body distribution of lipid nanocapsules were unaffected by the presence of acute lung inflammation. PMID:27180635

    Fatty acids, which are the major cardiac fuel, are derived from lipid droplets stored in cardiomyocytes, among other sources. The heart expresses hormone-sensitive lipase (HSL), which regulates triglycerides (TG) breakdown, and the enzyme is under hormonal control. Evidence obtained from adipose tissue suggests that testosterone regulates HSL activity. To test whether this is also true in the heart, we measured HSL activity in the left ventricle of sedentary male rats that had been treated with testosterone supplementation or orchidectomy with or without testosterone substitution. Left ventricle HSL activity against TG was significantly elevated in intact rats supplemented with testosterone. HSL activity against both TG and diacylglyceride was reduced by orchidectomy, whereas testosterone replacement fully reversed this effect. Moreover, testosterone increased left ventricle free fatty acid levels, caused an inhibitory effect on carbohydrate metabolism in the heart, and elevated left ventricular phosphocreatine and ATP levels as compared to control rats. These data indicate that testosterone is involved in cardiac HSL activity regulation which, in turn, may affect cardiac lipid and carbohydrate metabolism.

    The relationship between food availability and metabolic physiology was studied in groups of free-ranging baboons (Papio spp.) living in the Amboseli National Park and the Masai Mara National Reserve of Kenya. Three groups subsisted entirely on natural forage, while two other groups lived near tourist facilities and often consumed food wastes from these lodges. The refuse provided a very accessible food source with relatively high caloric density. Consumption of the refuse was associated with reduced locomotion. Sexually mature individuals from all five groups were sedated surreptitiously in the early morning and blood samples were collected. Compared to animals foraging exclusively in the wild, animals that supplemented their diet with the refuse items had two- to threefold elevations in serum insulin concentrations, as well as increased total cholesterol (C), HDL-C, and VLDL+LDL-C levels. No sex differences in physiological measures were observed except in body mass. Elevated serum insulin, and cholesterol and lipoprotein concentrations influence the development of cardiovascular disease and have been shown to be subject to dietary manipulation and exercise under controlled conditions. The present results suggest potentially deleterious effects of a highly accessible, calorically dense food source, and associated reduction of physical activity for baboons living in an otherwise natural environment.

  1. Serum IgE reactivity profiling in an asthma affected cohort.

    Tania Dottorini

    Full Text Available BACKGROUND: Epidemiological evidence indicates that atopic asthma correlates with high serum IgE levels though the contribution of allergen specific IgE to the pathogenesis and the severity of the disease is still unclear. METHODS: We developed a microarray immunoassay containing 103 allergens to study the IgE reactivity profiles of 485 asthmatic and 342 non-asthmatic individuals belonging to families whose members have a documented history of asthma and atopy. We employed k-means clustering, to investigate whether a particular IgE reactivity profile correlated with asthma and other atopic conditions such as rhinitis, conjunctivitis and eczema. RESULTS: Both case-control and parent-to-siblings analyses demonstrated that while the presence of specific IgE against individual allergens correlated poorly with pathological conditions, particular reactivity profiles were significantly associated with asthma (p<10E-09. An artificial neural network (ANN-based algorithm, calibrated with the profile reactivity data, correctly classified as asthmatic or non-asthmatic 78% of the individual examined. Multivariate statistical analysis demonstrated that the familiar relationships of the study population did not affect the observed correlations. CONCLUSIONS: These findings indicate that asthma is a higher-order phenomenon related to patterns of IgE reactivity rather than to single antibody reactions. This notion sheds new light on the pathogenesis of the disease and can be readily employed to distinguish asthmatic and non-asthmatic individuals on the basis of their serum reactivity profile.

    Cardiovascular disease (CVD) is the most important adult health problem in the world. Epidemiological studies and laboratory experiments have shown that fruit and vegetable consumption has protective effects against CVD. The purpose of the study was to investigate the effects of consumption of two kiwifruit per day on the lipid profile, antioxidants and markers of lipid peroxidation in hyperlipidemic adult men and women in Taiwan. Forty-three subjects who had hyperlipidemia, including 13 males and 30 females, participated in this study. They were asked to consume two kiwifruit per day for 8 weeks. Anthropometric measurements were made. Before the intervention and at 4 and 8 weeks of the intervention, fasting blood samples were analyzed for total cholesterol, triacylglycerol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein cholesterol (HDL-C). Additionally vitamin E and vitamin C, the malondialdehyde + 4-hydroxy-2(E)-nonenal concentration, and the lag time of LDL oxidation were determined. No significant differences from baseline to 8 weeks of the intervention were detected for triacylglycerol, total cholesterol, or LDL cholesterol. However, after 8 weeks of consumption of kiwifruit, the HDL-C concentration was significantly increased and the LDL cholesterol/HDL-C ratio and total cholesterol/HDL-C ratio were significantly decreased. Vitamin C and vitamin E also increased significantly. In addition, the lag time of LDL oxidation and malondialdehyde + 4-hydroxy-2(E)-nonenal had significantly changed at 4 and 8 weeks during the kiwifruit intervention. Regular consumption of kiwifruit might exert beneficial effects on the antioxidative status and the risk factors for CVD in hyperlipidemic subjects.

    Some risk factors associated with coronary heart disease (CHD) were evaluated in patients with different types of anorexia nervosa (AN). Anthropometric parameters, serum cholesterol, triglycerides and apoprotein (apo) B values, blood pressure and pulse rate were tested in 29 young female patients and 16 controls. Cholesterol, triglycerides and apo B were higher at the acute period of the illness (AN1), whereas at the chronic period the values of these parameters tended to normalize. Triglycerides were higher in patients who binge ate (bulimarexia). Systolic blood pressure decreased in all types of AN, while diastolic blood pressure decreased only in AN1; pulse rate was not altered. According to cholesterol and apo B values, AN patients may be at risk of CHD if they remain at low body weight. PMID:1855497

DESIGN AND METHODS: In this study, we included 2647 participants who were ≥ 40 years old and had normal serum lipid levels. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI equation was used to estimate the GFR. A mildly reduced eGFR was defined as 60-90 mL/min/1.73 m(2. First, multiple linear regression analysis was used to estimate the association of lipid profiles with the eGFR. Then, the levels of each lipid component were divided into four groups, using the 25th, 50th and 75th percentiles as cut-off points. Finally, multiple logistic regression analysis was used to investigate the association of different lipid components with the risk of mildly reduced eGFR. RESULTS: In the group with a mildly reduced eGFR, TG and LDL-C levels were significantly increased, but HDL-C levels were significantly decreased. After adjusting for age, gender, body mass index (BMI, systolic blood pressure (SBP, glycated hemoglobin (HbA1c, smoking and drinking, only TC and TG were independently related to the eGFR. Additionally, only TG showed a linear relationship with an increased risk of a mildly reduced eGFR, with the highest quartile group (TG: 108-150 mg/dl [1.22-1.70 mmol/L] having a significantly increased risk after adjusting for the above factors. CONCLUSIONS: Triglyceride levels are closely associated with a mildly reduced eGFR in subjects with normal serum lipid levels. Dyslipidemia with lower TG levels could be used as new diagnostic criteria for subjects with mildly reduced renal function.

    Nonbilayer lipids can be defined as cone-shaped lipids with a preference for nonbilayer structures with a negative curvature, such as the hexagonal phase. All membranes contain these lipids in large amounts. Yet, the lipids in biological membranes are organized in a bilayer. This leads to the question: what is the physiological role of nonbilayer lipids? Different models are discussed in this review, with a focus on the lateral pressure profile within the membrane. Based on this lateral pressure model, predictions can be made for the effect of nonbilayer lipids on peripheral and integral membrane proteins. Recent data on the catalytic domain of Leader Peptidase and the potassium channel KcsA are discussed in relation to these predictions and in relation to the different models on the function of nonbilayer lipids. The data suggest a general mechanism for the interaction between nonbilayer lipids and membrane proteins via the membrane lateral pressure. PMID:15519321

    Full Text Available Backgroud: Both alcohol consumption and the proprotein convertase subtilisin/kexin type 9 (PCSK9 gene polymorphism modulate serum lipid levels, but their interactions on serum lipid profiles are still unknown. The present study was undertaken to detect the interactions of PCSK9 E670G polymorphism and alcohol consumption on serum lipid levels.Methods: Genotypes of the PCSK9 E670G in 1352 unrelated subjects (785 non-drinkers and 567 drinkers were determined by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. The interactions between PCSK9 E670G genotypes and alcohol consumption on serum lipid parameters were detected by using a factorial design covariance analysis after controlling for potential confounders.Results: The levels of serum triglyceride, high-density lipoprotein cholesterol, apolipoprotein (Apo A1, and the ratio of ApoA1 to ApoB were higher in drinkers than in non-drinkers (P < 0.01 for all, whereas the levels of total cholesterol (TC, low-density lipoprotein cholesterol (LDL-C and ApoB were lower in drinkers than in non-drinkers (P < 0.001 for all. The genotypic and allelic frequencies of PCSK9 E670G were not different between non-drinkers and drinkers (P > 0.05 for each. The subjects with AA genotype in non-drinkers had higher serum LDL-C levels than the subjects with AG genotype, whereas the subjects with AG genotype in drinkers had higher serum TC levels than the subjects with AA genotypes (P < 0.05 for each. The effects of alcohol consumption on TC and LDL-C levels depended upon genotypes, the subjects with AA genotype had lower serum TC and LDL-C levels in drinkers than in non-drinkers.Conclusions: Alcohol consumption can modify the effects of the PCSK9 E670G polymorphism on serum TC and LDL-C levels. The subjects with AA genotype of the PCSK9 E670G benefit more from alcohol consumption than the subjects with AG genotype in

    Full Text Available Abstract Background Schisandra, a globally distributed plant, has been widely applied to health care products. Here, we investigated the effects of dietary intake of Fructus Schisandrae chinensis (FSC, both aqueous and ethanolic extracts (AqFSC, EtFSC, on serum/hepatic lipid contents in normal diet (ND- and high-fat/cholesterol/bile salt diet (HFCBD-fed mice. Methods Male ICR mice were fed with ND or HFCBD, supplemented with 1 and 4% of AqFSC and EtFSC, respectively, or 0.1% fenofibrate, for 13 days. Lipids were determined according to the manufacture’s instructions. Results EtFSC, but not AqFSC, significantly elevated hepatic triglyceride (TG in mice fed with ND. Feeding mice with HFCBD increased serum total cholesterol (TC, high density lipoprotein (HDL and low density lipoprotein (LDL levels as well as alanine aminotransferase (ALT activity. Supplementation with AqFSC, EtFSC or fenofibrate significantly reduced hepatic TC and TG levels. However, AqFSC and EtFSC supplementation increased serum HDL and LDL levels in mice fed with HFCBD. Fenofibrate increased serum HDL and reduced serum LDL contents in hypercholesterolemic mice. EtFSC reduced, but fenofibrate elevated, serum ALT activity in both normal and hypercholesterolemic mice. While fenofibrate reduced serum TC, TG, and HDL levels in mice fed with ND, it increased serum HDL and reduced serum LDL and TC levels in mice fed with HFCBD. Hepatomegaly was found in normal and hypercholesterolemic mice fed with diet supplemented with fenofibrate. Conclusions Feeding mice with AqFSC and EtFSC ameliorated the HFCBD-induced hepatic steatosis. In addition, EtFSC may offer protection against hepatic injury in hypercholesterolemic mice.

    Full Text Available The aim of this model study was to investigate how selected gut functions and serum lipid profile in rats on high-fat diets differed according to the type of fat (saturated vs. unsaturated and carbohydrate (simple vs. complex. The experiment was conducted using 32 male Wistar rats distributed into 4 groups of 8 animals each. For 4 weeks, the animals were fed group-specific diets that were either rich in lard or soybean oil (16% of the diet as the source of saturated or unsaturated fatty acids, respectively; further, each lard- and soybean oil-rich diet contained either fructose or corn starch (45.3% of the diet as the source of simple or complex carbohydrates, respectively. Both dietary factors contributed to changes in the caecal short-chain fatty acid concentrations, especially to the butyrate concentration, which was higher in rats fed lard- and corn starch-rich diets compared to soybean oil- and fructose-rich diets, respectively. The lowest butyrate concentration was observed in rats fed the soybean oil- and fructose-rich diet. On the other hand, the lard- and fructose-rich diet vs. the other dietary combinations significantly increased serum total cholesterol concentration, to more than two times serum triglyceride concentration and to more than five times the atherogenic index. In conclusion, a high-fat diet rich in fructose can unfavorably affect gut metabolism when unsaturated fats are predominant in the diet or the blood lipids when a diet is rich in saturated fats.

    Full Text Available Coronary arteries are subjected daily in high shear stress and manifest atherosclerosis very early in life in comparison to other arteries in the human body. Some factors that are implicated in the evolution and progress of this process are the concentration of lipids and arachidonic acid metabolites, such prostacyclin and thromboxane. It has been reported that those who participate in aerobic activities such as walking, cycling, jogging or brisk walking might have normal values of the mentioned chemical substances. On the other hand, it is reported that the effects of anaerobic and strength activities has negative effects on the vascular endothelium, which is essential for the maintenance of hemostatic balance and the local regulation of vascular tone.Therefore, even although extensive research has been conducted in this field, there are crucial gaps in our knowledge. Consequently, the purpose of this brief review is to describe what is known about the effects of anaerobic activities in which the competitive athletes have participated on the following blood parameters: Total cholesterol, triglycerides, high density lipoprotein cholesterol (HDL - C, low density lipoproteins cholesterol (LDL - C, prostacyclin & thromboxane.

    Full Text Available INTRODUCTION: Erythrocytes carry apolipoprotein B on their membrane, but the determining factors of erythrocyte-bound apolipoprotein B (ery-apoB are unknown. We aimed to explore the determinants of ery-apoB to gain more insight into potential mechanisms. METHODS: Subjects with and without CVD were included (N = 398. Ery-apoB was measured on fresh whole blood samples using flow cytometry. Subjects with ery-apoB levels ≤ 0.20 a.u. were considered deficient. Carotid intima media thickness (CIMT was determined as a measure of (subclinical atherosclerosis. RESULTS: Mean ery-apoB value was 23.2% lower in subjects with increased CIMT (0.80 ± 0.09 mm, N = 140 compared to subjects with a normal CIMT (0.57 ± 0.08 mm, N = 258 (P = 0.007, adjusted P<0.001. CIMT and ery-apoB were inversely correlated (Spearman's r: -0.116, P = 0.021. A total of 55 subjects (13.6% were considered ery-apoB deficient, which was associated with a medical history of CVD (OR: 1.86, 95% CI 1.04-3.33; adjusted OR: 1.55; 95% CI 0.85-2.82. Discontinuation of statins in 54 subjects did not influence ery-apoB values despite a 58.4% increase in serum apolipoprotein B. Subjects with blood group O had significantly higher ery-apoB values (1.56 ± 0.94 a.u. when compared to subjects with blood group A (0.89 ± 1.15 a.u, blood group B (0.73 ± 0.1.12 a.u. or blood group AB (0.69 ± 0.69 a.u. (P-ANOVA = 0.002. CONCLUSION: Absence or very low values of ery-apoB are associated with clinical and subclinical atherosclerosis. While serum apolipoprotein B is not associated with ery-apoB, the ABO blood group seems to be a significant determinant.

    Insect feeding behavior is regulated by many intrinsic factors, including hemolymph nutrient levels. Adipokinetic hormone (AKH) is a peptide factor that modulates hemolymph nutrient levels and regulates the nutritional state of insects by triggering the transfer of lipids into the hemolymph. We recently demonstrated that RNA interference (RNAi)-mediated knockdown of the AKH receptor (AKHR) reduces hemolymph lipid levels, causing an increase in the feeding frequency of the two-spotted cricket, Gryllus bimaculatus. This result indicated that reduced hemolymph lipid levels might motivate crickets to feed. In the present study, to elucidate whether hemolymph lipid levels contribute to insect feeding behavior, we attempted to manipulate hemolymph lipid levels via the lipophorin (Lp)-mediated lipid transferring system in G. bimaculatus. Of the constituent proteins in Lp, we focused on apolipophorin-III (GrybiApoLp-III) because of its possible role in facilitating lipid mobilization. First, we used RNAi to reduce the expression of GrybiApoLp-III. RNAi-mediated knockdown of GrybiApoLp-III had little effect on basal hemolymph lipid levels and the amount of food intake. In addition, hemolymph lipid levels remained static even after injecting AKH into GrybiApoLp-IIIRNAi crickets. These observations indicated that ApoLp-III does not maintain basal hemolymph lipid levels in crickets fed ad libitum, but is necessary for mobilizing lipid transfer into the hemolymph following AKH stimulation. Second, Lp (containing lipids) was injected into the hemolymph to induce a temporary increase in hemolymph lipid levels. Consequently, the initiation of feeding was delayed in a dose-dependent manner, indicating that increased hemolymph lipid levels reduced the motivation to feed. Taken together, these data validate the importance of basal hemolymph lipid levels in the control of energy homeostasis and for regulating feeding behavior in crickets. PMID:27144650

    Full Text Available Ramadan is the holiest month in the Islamic calendar and Muslims fast during this month. We designed this study to evaluate the effect of Ramadan fasting on plasma lipids profile and serum glucose among healthy Jordanian students. Ramadan fasting entails major changes in sleep pattern, physical activity and eating habits, which may cause changes in metabolism both in health and disease. This cohort study was performed during Ramadan in October 2006 (Islamic year 1427. The subjects were 70 healthy Jordanian students (male and female from three Jordanian universities who fasted during Ramadan. Their mean age was 21 ±1.6 years. We evaluated some anthropometric parameters as body weight (Kg, pulse rate (per minute and systolic and diastolic blood pressure (mmHg. All parameters at 4 week of Ramadan were significantly lower than pre-Ramadan values, 2 weeks after Ramadan fasting, body weight and other parameters had a trend to recoup to pre-Ramadan status; however, they were still lower than the pre-Ramadan values. We evaluated blood glucose, triglycerides (TG, cholesterol, low-density lipoprotein LDL, high-density lipoprotein (HDL, and Triglycerides at 1 day before, at week 1, 2, 4 of the Ramadan month and after tow weeks after the end of Ramadan. It was found that high-density lipoprotein (HDL cholesterol increased significantly during Ramadan, which indicated positive association with pulse rate and fat intake and negative association with systolic blood pressure and weight. . The LDLc was significantly reduced at the end of fasting. A reduction in the average TC value was observed at the end of fasting but the difference was not statistically and there no significant rise in the TG and blood sugar values at the end of fasting. This study indicated that Ramadan fasting led to a decrease weight, LDLc significantly, and significant not statistically reduction in the average TC value, and significantly increasing in HDLc was noted during Ramadan

    Objective Effects of red palm oil on major plasma carotenoids, tocopherol, retinol and serumlipids were evaluated when used in Chinese diet. Methods Red palm oil group (RPO) composed of 20 male subjects(aged 18-32) and soybean oil group (SBO) composed of 22 male subjects (aged18-32). Dietary fat provided about 28% of total calories, and the test oil accounted for about 60% of total dietary fat. In the 3 weeks of pretest period, diets were prepared with soybean oil, and then in the next 6 weeks subjects in each group consumed the diet prepared by test oil. Results Plasmaα-carotene, β-carotene and lycopene concentration of RPO group significantly increased at the time of interim (21 days) and of the end (42 days) (P<0.05), and α-tocopherol concentration significantly increased at the time of the end (42 days) in this study. Though Chinese plasma retinol level was relatively low when compared with that of Westerners, red palm oil diet showed no significant effect on adult Chinese plasma retinol level. Serum concentration of total cholesterol, triglyceride, high density lipoprotein cholesterol, apolipoprotein AI and apolipoprotein B of all subjects showed no significant changes in RPO group during the study. Conclusions The data in our study suggest that red palm oil is a good source of carotenoids and vitamin E when used in Chinese diet preparation, and it can significantly increase plasma concentration of α-carotene, β-carotene, lycopene andα-tocopherol.

    Full Text Available Fructooligosaccharide (FOS is a prebiotic, becoming apparent for its therapeutic role for diseased conditions like CHD, hypertension, diabetes and obesity. CHD and hypertension are one of the most prevalent NCD’s encountered in diabetic adults. Present study aims to assess the effect of FOS supplementation in type 2 diabetic adults on their lipemic, biophysical parameters and gut microflora parameters. A cross-sectional study was designed with 65 adult type 2 diabetics enrolled from Health clinic of The M.S. University of Baroda, Gujarat. All the subjects were randomly divided into two groups control and experimental. The experimental group was given 10 g of fructooligosaccharide and compared with the controls for lipemic parameters, hypertension and fecal counts in terms of lactic acid bacteria, bifidobacteria and enteric pathogen. Eight week supplementation of FOS resulted in an appreciable reduction in serum TC, TG and LDL levels by 10%, 4.9% and 7.8% respectively. A significant reduction (p<0.05 in systolic blood pressure was also observed as a result of FOS supplementation in the experimental group. A decline was seen in TC/HDL, LDL/HDL and non-HDL by 10.4%, 7.6% and 6.6% respectively (p<0.05, p<0.001. Gut microbiota values exhibited a significant increment in fecal log10 counts of Lactic acid bacteria and bifidobacteria by 9.3% and 10.9% respectively (p<0.001 while a significant reduction by 4.8% (p<0.001 was observed for Enteric pathogen. These outcomes revealed an efficacy of FOS in reducing serum lipid parameters, systolic BP and improving the gut microbiota in type 2 diabetic adults

    Positive reinforcement training (PRT) techniques have received considerable attention for their stress reduction potential in the behavioral management of captive nonhuman primates. However, few published empirical studies have provided physiological data to support this position. To address this issue, PRT techniques were used to train chimpanzees (Pan troglodytes) to voluntarily present a leg for an intramuscular (IM) injection of anesthetic. Hematology and serum chemistry profiles were collected from healthy chimpanzees (n=128) of both sexes and various ages during their routine annual physical examinations over a 7-year period. Specific variables potentially indicative of acute stress (i.e., total white blood cell (WBC) counts, absolute segmented neutrophils (SEG), glucose (GLU) levels, and hematocrit (HCT) levels) were analyzed to determine whether the method used to administer the anesthetic (voluntary present for injection vs. involuntary injection) affected the physiological parameters. Subjects that voluntarily presented for an anesthetic injection had significantly lower mean total WBC counts, SEG, and GLU levels than subjects that were involuntarily anesthetized by more traditional means. Within-subjects analyses revealed the same pattern of results. This is one of the first data sets to objectively demonstrate that PRT for voluntary presentation of IM injections of anesthetic can significantly affect some of the physiological measures correlated with stress responses to chemical restraint in captive chimpanzees.

    A clinical study was performed to examine the effect of the edible mushroom, Grifola gargal, on bone turnover markers and serum lipids in middle-aged and elderly Japanese women. Postmenopausal women aged 51-73 years (mean age, 61 years) received daily oral administration of 5 g G. gargal fruiting bodies (hot air-dried and powdered; G. gargal powder [GGP]). Serum levels of bone alkaline phosphatase (BAP) and lipids and urinary deoxypyridinoline (DPD) levels were measured before and 2 weeks after the start of GGP treatment. As a result, urinary DPD bone resorption marker levels in women treated with GGP decreased significantly. Serum levels of the BAP bone formation marker also tended to increase, but the difference was not significant. By contrast, the atherogenic index decreased and the high-density lipoprotein (HDL) ratio increased significantly. However, there were no statistically significant differences in serum lipids of total cholesterol, HDL cholesterol, and low-density lipoprotein cholesterol. In addition, this study demonstrated for the first time that G. gargal is safe for human consumption. PMID:27279439

    Full Text Available Abstract Background Short-term OE (oleoyl-estrone treatment causes significant decreases in rat weight mainly due to adipose tissue loss. The aim of this work was to determine if OE treatment affects the expression of genes that regulate lipid metabolism in white adipose tissue. Results Gene expression in adipose tissue from female treated rats (48 hours was analysed by hybridization to cDNA arrays and levels of specific mRNAs were determined by real-time PCR. Treatment with OE decreased the expression of 232 genes and up-regulated 75 other genes in mesenteric white adipose tissue. The use of real-time PCR validate that, in mesenteric white adipose tissue, mRNA levels for Lipoprotein Lipase (LPL were decreased by 52%, those of Fatty Acid Synthase (FAS by 95%, those of Hormone Sensible Lipase (HSL by 32%, those of Acetyl CoA Carboxylase (ACC by 92%, those of Carnitine Palmitoyltransferase 1b (CPT1b by 45%, and those of Fatty Acid Transport Protein 1 (FATP1 and Adipocyte Fatty Acid Binding Protein (FABP4 by 52% and 49%, respectively. Conversely, Tumour Necrosis Factor (TNFα values showed overexpression (198%. Conclusion Short-term treatment with OE affects adipose tissue capacity to extract fatty acids from lipoproteins and to deal with fatty acid transport and metabolism.

    Full Text Available Background: Choosing appropriate edible oils and right consumption amounts play an important role in the promotion of public health and prevention of chronic diseases. This study was aimed to evaluate the consumption level of various edible oils and factors affecting their selection among families in Kermanshah. Methods: This cross-sectional study was carried out on 500 families selected from six different areas using multi-stage cluster sampling method. Data were collected through face to face interview using a demographic questionnaire and a questionnaire about consumption of different edible oils. Descriptive statistics and regression and chi-square tests were applied to analyze the data. Results: The mean of edible oil consumption was 69.75±3.8 g/day per capita, more than half of which (34.7±2.2 g/day was supplied by hydrogenated fat. 31.4% of total daily energy intake was supplied by lipids from which 15.6% was supplied by hydrogenated fat, that is higher than the recommended level, maximum 10% (P<0.05. There was a positive relationship between socioeconomic status and rising consumption of oils instead of fats (r=0.2, P<0.001. Conclusion: This study showed that the daily consumption of hydrogenated fat was higher than half of the lipids consumed by families. Given the complications resulting from saturated fat consumption, decreasing the production of hydrogenated fat and increasing the nutritional knowledge of families through public media and educational programs are highly recommended.

    The main objective of this study was to investigate whether orally administered Korean grain larvae ethanol extract (GLE) had a bifidogenic effect in normal rats. Male Sprague–Dawley rats were divided into a negative control group (CO) and GLE orally administered (5.0, 7.0 and 9.0 mg/100 g body weight) groups. Thymus and spleen weights dosedependently increased by 128.58% and 128.58%, respectively, but abdominal fat decreased by 19.18% after GLE administration compared with that in the CO group (<0.05). Serum triglycerides, total cholesterol, low-density lipoprotein cholesterol, and glucose decreased by 30.26%, 7.33%, 27.20%, and 6.96%, respectively, whereas highdensity lipoprotein cholesterol increased by 129.93% in the GLE groups compared with those in the CO group (<0.05). IgG, IgM, IgA in the GLE groups increased 203.68%, 181.41%, and 238.25%, respectively, compared to that in the CO group (<0.05). Bifidobacteria and Lactobacillus increased by 115.74% and 144.28%, whereas Bacteroides, Clostridium, Escherichia, and Streptococcus decreased by 17.37%, 17.46%, 21.25%, and 19.16%, respectively, in the GLE groups compared with those in the CO group (<0.05). Total organic acids, acetic acid, and propionic acid increased by 151.40%, 188.09%, and 150.17%, whereas butyric acid and valeric acid decreased by 40.65% and 49.24%, respectively, in the GLE groups as compared with those in the CO group (<0.05). These results suggest that Korean GLE improves the bifidogenic effect by increasing cecal organic acids and modulating gut microflora via a selective increase in Bifidobacterium in normal rats.

    Full Text Available Background: Hyperlipidaemic is a risk factor of cardiovascular diseases. Recently, statins, life style modification and diet have been used to treat hyperlipidaemia. Aim: The present study was performed to evaluate the effect of lovastatin and exercise on hyperlipidaemic patients. Methods: This double-blind randomized clinical trial was performed on 80 patients over 30 years old, whose lipid profile was HDL ≤35 mg/dl, LDL ≥160 mg/dl, triglyceride ≥200 mg/dl, and cholesterol ≥200. At first, 96 hyperlipidemic patients were included in this study, 7 out of them were excluded because of HTN (hypertension and HLP (hyperlipidaemia and 9 due to diabetes. The patients were randomly divided into two groups: the first group took lovastatin 40 mg daily, the second group was instructed to walk 35 minutes a day, 3 days a week. After 6 weeks trial, data were analyzed using t-test, Wilcoxon signed sample test, Kolomogorou-Smirnov test, Mann-Whitney test, and Leveus test. Results: The average age was 55.18±9.9. 59 out of 80 (73.7% were men and 21 were women (26.3%. The average age of group 1(with lovastin was 55.12±8.4 years and in group 2 (exercise was 55.35±9.2. The average decrease in TG level in lovastatin treated (I and subjected to exercise (II groups was 21.4 mg/dl and 20.5 mg/dl (P<0.2 respectively. Cholesterol decrease in two groups was 41.3±44.3 mg/dl and 1.57±41.8 mg/dl (P<0.001 respectively. The average decrease in LDL level in I and II groups was 35.82±34.1and 8.55±28.1 (P<0.001.whereas, an average increase was shown in HCL level: 5.45±14.4mg/dl and 0.4±12.3 mg/dl (P-value = 0.09 respectively. Conclusion: The results showed that exercise could reduce LDL, but lovastatin can reduce total cholesterol, TG and can increase HDL. Therefore in the management of hyperlipidaemia, exercise should be combined with lovastatin therapy to achieve a better outcome.

    Objective:To study the blood iron and zinc levels in patients with type 2 diabetes mellitus and their relationship with glucose and lipid metabolism.Methods:Patients with type 2 diabetes mellitus were enrolled in T2DM group and healthy people were enrolled in control group. T2DM patients were divided into low iron and zinc group and high iron and zinc group with the median of serum iron and zinc contents as the standard. Serum trace elements contents and glucose and lipid metabolism indicators were detected.Results:T2DM patients’ blood iron contents were significantly higher than those of the control group while the zinc contents were significantly lower than those of the control group. Copper, calcium and magnesium contents had no significant difference between two groups of patients. HbA1c%, glucagon and HOMA-IR as well as apoB, apoE, ApoM, leptin and vaspin contents in high iron group were higher than those in low iron group while serum insulin, GLP-1, GIP, ApoA1, APN and HOMA-β levels were lower than those in low iron group. HbA1c%, glucagon, HOMA-IR, apoB, apoE, ApoM, leptin and vaspin contents in high zinc group were lower than those in low zinc group while serum insulin, GLP-1, GIP, ApoA1, APN and HOMA-β levels were higher than those in low zinc group.Conclusions: the serum iron level was abnormally high and the zinc content was abnormally low in patients with type 2 diabetes mellitus. Serum iron and zinc levels were closely related to the glucose and lipid metabolism.

    The effects of consuming foods containing 0 (control), 3.4, 6.8, or 10.2 g psyllium seed husk (PSH)/d for 24 wk on the serum lipid profile were assessed in this randomized, double-blind controlled study. Men and women (n = 286) with LDL-cholesterol concentrations between 3.36 and 5.68 mmol/L (130 and 220 mg/dL) were randomly assigned to one of four treatment groups after following a low-fat diet for > or = 8 wk. At week 24, LDL cholesterol was 3% above baseline in the control group. In the group consuming 10.2 g PSH/d, LDL cholesterol remained below baseline during treatment, with a value 5.3% below that of the control group at week 24 (P < 0.05 compared with the control group). No significant differences were observed in HDL cholesterol or triacylglycerol. Although modest, the effect of 10.2 g PSH/d on LDL cholesterol (relative to the control) persisted throughout the 24-wk treatment period, indicating potential for long-term benefit. PMID:9497178

    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.

    Full Text Available The plasma membrane is an important organelle providing structure, signaling and transport as major biological functions. Being composed of lipids and proteins with different physicochemical properties, the biological functions of membranes depend on specific protein-protein and protein-lipid interactions. Interactions of proteins with their specific sterol and lipid environment were shown to be important factors for protein recruitment into sub-compartmental structures of the plasma membrane. System-wide implications of altered endogenous sterol levels for membrane functions in living cells were not studied in higher plant cells. In particular, little is known how alterations in membrane sterol composition affect protein and lipid organization and interaction within membranes. Here, we conducted a comparative analysis of the plasma membrane protein and lipid composition in Arabidopsis sterol-biosynthesis mutants smt1 and ugt80A2;B1. smt1 shows general alterations in sterol composition while ugt80A2;B1 is significantly impaired in sterol glycosylation. By systematically analyzing different cellular fractions and combining proteomic with lipidomic data we were able to reveal contrasting alterations in lipid-protein interactions in both mutants, with resulting differential changes in plasma membrane signaling status.

    Full Text Available Abstract Background This study was designed to evaluate the effects of a 24-month period of moderate exercise on serum lipids in menopausal women. Methods The subjects (40–60 y were randomly divided into an exercise group (n = 14 and a control group (n = 13. The women in the exercise group were asked to participate in a 90-minute physical education class once a week and to record their daily steps as measured by a pedometer for 24 months. Results Mean of daily steps was significantly higher in the exercise group from about 6,800 to over 8,500 steps (P P Conclusions These results suggest that daily exercise as well as increasing the number of daily steps can improve the profile of serum lipids.

    Peroxisome proliferators activated receptor alpha (PPARalpha) regulates the transcription of several proteins involved in human lipoprotein metabolism. We screened the PPARA locus for polymorphisms in 20 unrelated subjects from each of three ethnic groups (Chinese, Malays and Asian Indians). Only the V227A polymorphism was observed. We genotyped 4248 subjects (2899 Chinese, 761 Malay and 588 Asian Indians) and found allele frequencies for the A227 allele of 0.04 in Chinese, 0.006 in Malays and 0.003 in Asian Indians. We examined the associations between this polymorphism and serum lipid concentrations in Chinese. In women, but not in men, the presence of the A227 allele was associated with lower serum concentrations of total cholesterol [5.38mmol/l (95%CI: 5.22-5.54) versus 5.21mmol/l (95%CI: 4.99-5.43), p=0.047] and triglycerides [1.19mmol/l (95%CI: 1.10-1.28) versus 1.09mmol/l (95%CI: 0.98-1.21), p=0.048]. We also found that the V227A polymorphism modulates the association between dietary polyunsaturated fatty acid intake and serum high density lipoprotein concentration (p-value for interaction=0.049). Our findings implicate PPARalpha in the lipid lowering associated with diets high in PUFA and suggests that genetic variation at the PPARA locus may determine the lipid response to changes in PUFA intake.

    The pulp of Dacryodes edulis G.Don which is rich in oils is commonly consumed in Nigeria when in season. The effect of diet supplementation with edulis fruit pulp oil on body lipid parameters was evaluated in male Wistar albino rats. D. edulis oil was extracted in n-hexane. The test diet was.compounded using the oil extract (10%), whereas the control animals were kept on control diet formulated with groundnut oil (10%). After six weeks, the animals were anaesthetized with chloroform and blood samples collected through cardiac puncture for the determination of serum lipid profile. Results revealed that D. edulis fruit pulp oil did not cause any significant (p > 0.05) alterations in serum total cholesterol, LDL-cholesterol and triacylglycerol. The total amount of lipids present in the serum was increased by 33.3%, whereas the quantity of liver lipids decreased by the same factor (33.3%). Insignificant (p > 0.05) increases in the weights (g 100 g(-1) BW) of the liver (2.91 ± 0.17 to 3.38 ± 0.25), kidney (0.36 ± 0.06 to 0.40 ± 0.02) and heart (0.32 ± 0.02 to 0.33 ± 0.04) were observed in the test group. No significant change (p > 0.05) in the average body weight of the test animals was recorded. HPLC analysis of D. edulis oil showed that it contained palmitic acid (48.7%), linoleic acid (28.6%),oleic acid (12.9%), stearic acid (5.0%), lauric acid (2.2%), linolenic acid (1.7%) and myristic acid (0.9%). The peroxide value of the oil was 0.00. Prolonged intake of D. edulis fruit pulp oil may induce adverse effects on the body organs, even though the body lipid profile remains unaltered.

    Full Text Available One of the most important risk factors for CHD is dyslipidemia, among others hypercholesterolemia or high LDL-cholesterol. Plant-sterols or phytosterols (PS are among dietary factors known to lower blood cholesterol as part of therapeutic life-style changes diet. This study was aimed to evaluate the effect of PS properly solubilized in a-partly vegetable oil-filled low fat milk, on serum lipid levels in mild-moderate hypercholesterolemic subjects. Randomized, two-arm parallel control group trial was conducted at Department of Nutrition-University of Indonesia in Jakarta from June to November 2006. Each subject was randomly assigned to receive dietary life-style changes counseling plus 1.2 g phytosterol/day in low-fat milk (PS-group or control group receiving the counseling alone for six weeks period. There were no significant changes of serum total and LDL-cholesterol of control group after a six week of dietary counseling (respectively 218.3 ± 18.6 mg/dL to 219.6 ± 24.3 mg/dL and 164.7±21.8 mg/dL to 160.0±26.4 mg/dL. There were a significant decreases of serum total and LDL-cholesterol (respectively p=0.01 and p=0.004 among subjects receiving PS after a six weeks observation period (respectively 233.5±24.6 mg/dL to 211.2±30.3 mg/dL and 176.9±24.7 mg/dL to 154.5±24.3 mg/dL. There was a significant difference in the LDL-lowering effects (p=0.024 among the PS-group after a six weeks (22.4±27.9 mg/dL as compared to the control group (4.7±17.2 mg/dL. No significant changes were found on serum HDL-cholesterol and triglyceride levels in both groups. Although there was no significant difference found in daily nutrients intake between the-2 groups, however, significant reductions in body weight, body mass index and waist circumference were found only in the PS group (p=0.000; 0.000; 0.003, respectively. It is concluded that the lowering of total and LDL-cholesterol in those receiving life-style changes counseling plus 1.2 g PS daily for six

    To investigate the effects of the traditional Chinese medicines, kuei-lu-erh-hsien-chiao and chia-wei-hsiao-yao-san, on the cardiovascular systems of mimic menopausal rats, five groups were formed: group 1 (the control group) was given a sham operation and received distilled water, while groups 2, 3, 4 and 5 were ovariectomized and received distilled water, kuei-lu-erh-hsien-chiao, chia-wei-hsiao-yao-san and 17-beta-estradiol, respectively, for4 months. Our results demonstrated that the mean differences of the estrogen levels in groups 3 or 5 were significantly higher than those of group 2. These data suggest that there might be some estrogen-like substances in kuei-lu-erh-hsien-chiao. However, the function of these estrogen-like substances was unknown. The mean differences of the triglyceride (TG) levels, high-density lipoprotein cholesterol (HDL-C) levels, low-density lipoprotein cholesterol (LDL-C) levels, and the ratios of TC/HDL-C and LDL-C/HDL-C in groups 1, 3, 4 and 5 were not significantly different from those in group 2. The mean differences of the total cholesterol (TC) levels in group 5 were significantly higher than those in group 2 (p chia-wei-hsiao-yao-san declines the Hcy levels in OVX rats and does not affect the TC levels in these animals. In conclusion, our results indicate that chia-wei-hsiao-yao-san shows a more profound effect than 17-beta-estradiol in the prevention of atherosclerosis in these OVX rats. PMID:15481644

    The aim of this study was to assess how lipid emulsions for parenteral nutrition affect lipopolysaccharide (LPS)-induced acute monocyte inflammation in vitro. An 18 h long LPS induced human monocyte leukemia cell stimulation was performed and the cell-growth medium was supplemented with three different industrial lipid emulsions: Intralipid(®), containing long-chain triglycerides (LCT--soybean oil); Medialipid(®), containing LCT (soybean oil) and medium-chain triglycerides (MCT--coconut oil); and SMOFlipid(®), containing LCT, MCT, omega-9 and -3 (soybean, coconut, olive and fish oils). Cell viability and apoptosis were assessed by Trypan blue exclusion and flow cytometry respectively. Monocyte composition and membrane remodeling were studied using gas chromatography and NR12S staining. Microparticles released in supernatant were measured by prothrombinase assay. After LPS challenge, both cellular necrosis and apoptosis were increased (threefold and twofold respectively) and microparticle release was enhanced (sevenfold) after supplementation with Medialipid(®) compared to Intralipid(®), SMOFlipid(®) and monocytes in the standard medium. The monocytes differentially incorporated fatty acids after lipid emulsion challenge. Finally, lipid-treated cells displayed microparticles characterized by disrupted membrane lipid order, reflecting lipid remodeling of the parental cell plasma membrane. Our data suggest that lipid emulsions differentially alter cell viability, monocyte composition and thereby microparticle release. While MCT have deleterious effects, we have shown that parenteral nutrition emulsion containing LCT or LCT and MCT associated to n-3 and n-9 fatty acids have no effect on endotoxin-induced cell death and inflammation.

We decided to assess the preventive role of aqueous extract of Berberis Integerrima root on the serum levels of glucose, insulin, and lipid profile in Streptozotocin (STZ-induced diabetic rats.Materials and Methods: Forty male rats were divided into 5 groups as follows: 1- normal (N; 2- normal + barberry (N+B (they received barberry root extract for 6 weeks; 3- diabetic (D (they received STZ, 65 mg/kg BW /i.p.; 4- diabetic + barberry before (D+Bb (they received barberry root extract for 3 weeks before STZ injection and continued for another three weeks; and 5- diabetic + barberry after (D+Ba (three days after STZ injection, they received barberry root extract for 3 weeks. The experimental groups received barberry root extract (500 mg/kg bw intra gastric by gavage for 6 weeks and the experimental period for each rat was 6 weeks.Results: Diabetic rats showed a significant increase in serum glucose, total cholesterol, triglycerides, LDL-C, and food intake as well as a decrease in HDL-C, body weight and serum insulin, compared to the other groups. Administration of the barberry root extract in diabetic rats restored these changes towards normal to some extent.Conclusion: In this study, for the first time, we showed that the administration of the barberry root extract before diabetes induction resulted in better amelioration in the serum levels of glucose, insulin, and lipid profile, compared to the group receiving it after induction: this indicates that the barberry root extract can play both a preventive and a therapeutic role in such patients.

  18. Effects of canola oil supplemented with atherogenic element and nigella sativa (kalonji) on serum lipids in albino rats - an experimental study

    International Nuclear Information System (INIS)

    To compare effects of canola oil supplemented with atherogenic element and Nigella sativa on serum lipids in albino rats. Place and Duration of Study: Study was conducted at Pathology Department of Postgraduate Medical Institute, for 12 weeks. Study Design: Laboratory based randomized controlled trials. Material and Methods: Seventy two albino rats were selected and randomly divided into six groups of twelve animals with equal number of male and female in each. Fourteen days after acclimatization to the environment and basal diet, fasting blood samples (zero week) were collected by heart puncture under ether anesthesia and experimental diets were started which were continued for 12 weeks. All parameters were measured using enzymatic colorimetric methods. Results: Estimations of serum lipids showed increase in total cholesterol (TC) and High Density Lipoprotein Cholesterol (HDL-c) levels but fall in LDL-c concentrations in groups fed on canola oil diet. On the other hand, even atherogenic supplemented groups had decrease in cardio-protective HDL-c and raised LDL-c; although statistically non-significant. Thus canola oil diets were not hyperlipidaemic and prevented adiposity. Nigella sativa (NS) diets significantly decreased serum total cholesterol and LDL-c while HDL-c was raised but non-significantly. Thus Nigella sativa prevented deposition of lipids in tissues, thus preventing tendency to obesity and atherogenesis by decreasing LDL-c in serum. Conclusion: Nigella sativa produces antilipidaemic and anti-obesity effects by decreasing low density lipoprotein cholesterol level which is statistically significant in two out of the three groups fed on Ns; it also increased high density cholesterol which was however non-significant in comparison with Canola oil alone.

    It is unknown whether components present in heart failure (HF) patients' serum provide an angiogenic stimulus. We sought to determine whether serum from HF patients affects angiogenesis and its major modulator, the Notch pathway, in human umbilical vein endothelial cells (HUVECs). In cells treated with serum from healthy subjects or from patients at different HF stage we determined: (1) Sprouting angiogenesis, by measuring cells network (closed tubes) in collagen gel. (2) Protein levels of Notch receptors 1, 2, 4, and ligands Jagged1, Delta-like4. We found a higher number of closed tubes in HUVECs treated with advanced HF patients serum in comparison with cells treated with serum from mild HF patients or controls. Furthermore, as indicated by the reduction of the active form of Notch4 (N4IC) and of Jagged1, advanced HF patients serum inhibited Notch signalling in HUVECs in comparison with mild HF patients' serum and controls. The circulating levels of NT-proBNP (N-terminal of the pro-hormone brain natriuretic peptide), a marker for the detection and evalutation of HF, were positively correlated with the number of closed tubes (r = 0.485) and negatively with Notch4IC and Jagged1 levels in sera-treated cells (r = -0.526 and r = -0.604, respectively). In conclusion, we found that sera from advanced HF patients promote sprouting angiogenesis and dysregulate Notch signaling in HUVECs. Our study provides in vitro evidence of an angiogenic stimulus arising during HF progression and suggests a role for the Notch pathway in it. J. Cell.

  20. Do abnormal serum lipid levels increase the risk of chronic low back pain? The Nord-Trondelag Health Study.

    Ingrid Heuch

    Full Text Available Cross-sectional studies suggest associations between abnormal lipid levels and prevalence of low back pain (LBP, but it is not known if there is any causal relationship.The objective was to determine, in a population-based prospective cohort study, whether there is any relation between levels of total cholesterol, high density lipoprotein (HDL cholesterol and triglycerides and the probability of experiencing subsequent chronic (LBP, both among individuals with and without LBP at baseline.Information was collected in the community-based HUNT 2 (1995-1997 and HUNT 3 (2006-2008 surveys of an entire Norwegian county. Participants were 10,151 women and 8731 men aged 30-69 years, not affected by chronic LBP at baseline, and 3902 women and 2666 men with LBP at baseline. Eleven years later the participants indicated whether they currently suffered from chronic LBP.Among women without LBP at baseline, HDL cholesterol levels were inversely associated and triglyceride levels positively associated with the risk of chronic LBP at end of follow-up in analyses adjusted for age only. Adjustment for the baseline factors education, work status, physical activity, smoking, blood pressure and in particular BMI largely removed these associations (RR: 0.96, 95% CI: 0.85-1.07 per mmol/l of HDL cholesterol; RR: 1.16, 95% CI: 0.94-1.42 per unit of lg(triglycerides. Total cholesterol levels showed no associations. In women with LBP at baseline and men without LBP at baseline weaker relationships were observed. In men with LBP at baseline, an inverse association with HDL cholesterol remained after complete adjustment (RR: 0.83, 95% CI: 0.72-0.95 per mmol/l.Crude associations between lipid levels and risk of subsequent LBP in individuals without current LBP are mainly caused by confounding with body mass. However, an association with low HDL levels may still remain in men who are already affected and possibly experience a higher pain intensity.

    In today's world wrong nutritional habits together with a low level of physical activity have given rise to the development of obesity and its comorbidity, insulin resistance. More specifically, many researches indicate that lipids are vitally involved in the onset of a peripheral tissue (e.g., skeletal muscle, heart, and liver) insulin resistance. Moreover, it seems that diabetes can also induce changes in respect of lipid composition of both the salivary glands and saliva. However, judging by the number of research articles, the salivary glands lipid profile still has not been sufficiently explored. In the current study we aim to assess the changes in the main lipid fractions, namely, triacylglycerols, phospholipids, free fatty acids, and diacylglycerols, in the parotid and the submandibular salivary glands of rats exposed to a 5-week high fat diet regimen. We observed that the high caloric fat diet caused a significant change in the salivary glands lipid composition, especially with respect to PH and TG, but not DAG or FFAs, classes. The observed reduction in PH concentration is an interesting phenomenon frequently signifying the atrophy and malfunctions in the saliva secreting organs. On the other hand, the increased accumulation of TG in the glands may be an important clinical manifestation of metabolic syndrome and type 2 diabetes mellitus. PMID:27471733

    Elevated serum levels of uric acid consistently correlate with hypertension, but the directionality of the association remains debated. To help define this relationship, we used a controlled setting within a homogeneous Amish community and the Mendelian randomization of a nonsynonymous coding single-nucleotide polymorphism, rs16890979 (Val253Ile), in the SLC2A9 gene. This gene expresses the GLUT9 transporter that also transports uric acid and is associated with lower serum uric acid levels. We studied the unconfounded association between genotype and blood pressure in 516 Amish adults, each placed for 6 days on standardized diets, first with high sodium, followed by low sodium, with an intervening washout period. Blood pressure, measured using 24-h ambulatory monitoring, during both diet periods was used as the primary outcome. All participants were free of diuretic or other antihypertensive medications and the relationships between GLUT9 genotype and both serum uric acid and blood pressure were assessed. Each copy of the GLUT9 minor Ile allele was found to confer a significant 0.44 mg/dl reduction in serum uric acid and was associated with a significant mean decrease in the systolic blood pressure of 2.2 and 1.5 mm Hg on the high- and low-sodium diet, respectively. Thus, a Mendelian randomization analysis using variants in the GLUT9 gene indicates that a decrease in serum uric acid has a causal effect of lowering blood pressure. PMID:22189840

    Full Text Available Background: Non-alcoholic fatty liver disease (NAFLD is becoming a public health problem worldwide and using microalgae is a new approach on its treatment. The aim of this study was to investigate the effect of Chlorella vulgaris supplementation on liver enzymes, serum glucose and lipid profile in patients with NAFLD. Methods: This double-blind randomized placebo-controlled clinical trial was conducted on 60 NAFLD patients from specialized clinics of Tabriz University of Medical Sciences from December 2011 to July 2012. The subjects were randomly allocated into 2 groups: 1 “intervention” (n=30 received 400 mg/day vitamin E plus four 300 mg tablets of Chlorella vulgaris and, 2 “placebo” (n=30 received 400 mg/day vitamin E and four placebo tablets per day for 8 weeks. Weight, liver enzymes and metabolic factors were assessed in fasting serum and dietary data was collected at baseline and end of the study. Results: Weight, liver enzymes, fasting blood sugar (FBS and lipid profile decreased significantly in both groups (P<0.05. The differences in weight, ALP and FBS between the two groups were statistically significant (P=0.01, P=0.04 and P=0.02, respectively. Conclusion: C. vulgaris seems to improve FBS and lipid profile and therefore could be considered as an effective complementary treatment in NAFLD.

    We investigated the effects of the polysaccharide from the sporophyll of a selected brown alga Undaria pinnatifida on serum lipid profile, fat tissue accumulation, and gastrointestinal transit time in rats fed a high-fat diet. The algal polysaccharide (AP) was prepared by the treatment of multiple cellulase-producing fungi Trichoderma reesei and obtained from the sporophyll with a yield of 38.7% (dry basis). The AP was mostly composed of alginate and fucoidan (up to 89%) in a ratio of 3.75:1. The AP was added to the high-fat diet in concentrations of 0.6% and 1.7% and was given to male Sprague-Dawley rats (5-wk-old) for 5 wk. The 1.7% AP addition notably reduced body weight gain and fat tissue accumulation, and it improved the serum lipid profile, including triglycerides, total cholesterol, and very low-density lipoprotein-cholesterol. The effects were associated with increased feces weight and shortened gastrointestinal transit time. In addition, the lipid peroxidation of the liver was decreased in both groups. PMID:27384013

    Full Text Available Background. Organism’s lipid peroxidation is one of the most often examined and known physiological process evoked by free radicals. It concerns oxidation reaction of unsaturated fatty acid and/or other lipids leading to lipid oxidation products (LOP, which as a result of further changes generate among others the malondialdehyde molecules. The aim of the work was an estimation if raw or cooked kale addition to rat’s diet infl uences antioxidant defense effi ciency in their organisms in comparison to rats fed with standard AIN-93G diet. Material and methods. The experiment was conducted with 36 Wistar strain, male rats over 21 days. The rats were divided into 3 groups (each 12 stuck which were fed with: standard diet AIN-93G (2 groups, AIN-93G diet with 10% addition of raw kale (2 groups, and AIN-93G with 10% addition of cooked lyophilised kale. The total content of polyphenols (FC method and antioxidant activity (ABTS+• were previously determined in raw and then in cooked kale. On the 20th day of experiment, half of rats (6 stuck of each kind of the diet were injected intraperitoneally by the solution of paraquat (PQ in physiological salt to evoke the oxidative stress. The next day animals were stunned and blood from their hearts was sampled. In the obtained serum, the levels of lipid oxidation products (LOP and malondialdehyde (MDA were assessed. Results. It was observed that in blood serum of rats fed with modifi ed diet with raw and cooked lyophilised kale addition the lipid oxides level was lower in comparison to control group fed with standard diet (p < 0.05. It was found that intoxication with paraquat caused growth of MDA and LOP levels in blood serum of all rats in comparison to not intoxicated groups but that growth was the lowest in group fed diet with cooked kale addition. Conclusion. Diet with kale, both raw and cooked, effi ciently inhibited the lipid peroxidation process in rats’ organisms, ongoing during natural metabolism

    Objective In order to investigate whether the presence of distant metastases is associated with serum lipid abnormalities. Methods The fasting serum lipid profile and various clinicopathological data of 324 breast cancer patients with and without synchronous distant metastases were collected and analyzed.The serum lipid profile,including total cholesterol (TC),triglycerides (TG),lowdensity (LDL-C) and high-density lipoprotein cholesterol (HDL-C) was determined.The nutritional status,the serum albumin was measured and body mass index (BMI) was calculated.Univariate analysis and multiple logistic regression analysis were carried out to investigate the association of serum lipid profile with distant metastases.Results Univariate analysis showed that the distant metastasis rate was significantly higher in the breast cancer patients with an higher level of serum TC,TG,LDL-C,and LDL-C/HDL-C ratio ( P < 0.05 ).Multiple logistic regression analysis showed that higher serum levels of TC,LDL-C and LDLC/HDL-C ratio were independent risk factors for distant metastasis in breast cancer ( OR =2.324,2.648and 4.862,respectively ). Conclusions Hyperlipidemia is significantly associated with the distant metastasis in breast cancer patients. Monitoring of serum lipid profile may be helpful to predict the occurrence of distant metastasis in breast cancer patients.%目的 测定乳腺癌患者的血脂相,包括总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇( LDL-C)和高密度脂蛋白胆固醇(HDL-C),以探讨乳腺癌远处转移与血脂异常的关系.方法 收集324例乳腺癌患者的临床病理资料和餐前血脂水平,并通过测定血清白蛋白和计算体重指数(BMI)评估患者的营养状态.采用单因素分析和多元Logistic回归法对血脂等临床病理因素与乳腺癌远处转移的关系进行统计学分析.结果 单因素分析显示,远处转移组患者的高TC血症、高TG血症、高LDL-C血症和高LDL-C/HDL-C比

    A 75-d experiment was conducted to evaluate the influence of dietary Cu concentrations on growth performance, serum lipid profiles, antioxidant defenses, and fur quality in growing-furring male blue foxes. Seventy-five male blue foxes (5.78 ± 0.09 kg BW) were selected and randomly allocated to 1 of the following 5 dietary treatments: 1) control (basal diet without supplemental Cu; 7.78 mg Cu/kg), 2) 12.22 mg/kg supplemental Cu (Cu20), 3) 32.22 mg/kg supplemental Cu, 4) 72.22 mg/kg supplemental Cu (Cu80), and 5) 152.22 mg/kg supplemental Cu (Cu160). A dry feed that consisted of animal meals, soybean meal, extruded corn, and soybean oil was used as the basal diet and Cu was supplemented as reagent grade CuSO∙5HO. The results showed that Cu supplementation increased the ADG ( 0.10). Additionally, Cu supplementation linearly increased the concentration of fecal Cu, liver Cu, serum total protein, and albumin ( < 0.01). Foxes in the Cu160 group had higher serum Cu concentration than those in the control and Cu20 groups ( < 0.05). The concentration of serum cholesterol decreased with dietary Cu supplementation ( < 0.05). Serum high-density lipoprotein, on the contrary, tended to increase with Cu supplementation ( = 0.09). Copper supplementation increased the activity of glutathione peroxidase ( < 0.05) and tended to increase the activity of serum ceruloplasmin ( = 0.07). For fur quality, skin length in the Cu80 group was greater than that in the control and Cu20 groups. In addition, hair color tended to deepen with the increasing of dietary Cu concentrations ( = 0.08). In conclusion, this study demonstrates that Cu supplementation can promote growth and increase fat digestibility and fur length. Additionally, dietary Cu supplementation can enhance antioxidant capacity and reduce serum cholesterol in growing-furring blue foxes. PMID:27065271

    The brain is especially susceptible to free radical attack since it is rich in polyunsaturated fatty acids and consumes very high amounts of oxygen. Melatonin is a non-enzymatic amphiphilic antioxidant hormone that is widely used in medicine for protective and treatment purposes in cases of oxidative stress. In the present work, the effects of the clinically used dose of melatonin (a single intraperitoneal dose of 100 mg/kg) on rat brain homogenate were investigated as a function of temperature using Fourier transform infrared spectroscopy. The results showed that the lipid to protein ratio decreases in the melatonin treated brain samples. Moreover, it is revealed that melatonin disorders and decreases the dynamics of lipids and induces a strengthening in the hydrogen bonding between the functional groups of both melatonin and the polar parts of lipids and/or water at physiological temperatures.

  10. Serum IGF-1 affects skeletal acquisition in a temporal and compartment-specific manner.

    Directory of Open Access Journals (Sweden)

    Hayden-William Courtland

    Full Text Available Insulin-like growth factor-1 (IGF-1 plays a critical role in the development of the growing skeleton by establishing both longitudinal and transverse bone accrual. IGF-1 has also been implicated in the maintenance of bone mass during late adulthood and aging, as decreases in serum IGF-1 levels appear to correlate with decreases in bone mineral density (BMD. Although informative, mouse models to date have been unable to separate the temporal effects of IGF-1 depletion on skeletal development. To address this problem, we performed a skeletal characterization of the inducible LID mouse (iLID, in which serum IGF-1 levels are depleted at selected ages. We found that depletion of serum IGF-1 in male iLID mice prior to adulthood (4 weeks decreased trabecular bone architecture and significantly reduced transverse cortical bone properties (Ct.Ar, Ct.Th by 16 weeks (adulthood. Likewise, depletion of serum IGF-1 in iLID males at 8 weeks of age, resulted in significantly reduced transverse cortical bone properties (Ct.Ar, Ct.Th by 32 weeks (late adulthood, but had no effect on trabecular bone architecture. In contrast, depletion of serum IGF-1 after peak bone acquisition (at 16 weeks resulted in enhancement of trabecular bone architecture, but no significant changes in cortical bone properties by 32 weeks as compared to controls. These results indicate that while serum IGF-1 is essential for bone accrual during the postnatal growth phase, depletion of IGF-1 after peak bone acquisition (16 weeks is compartment-specific and does not have a detrimental effect on cortical bone mass in the older adult mouse.

    AIM To investigate the relationship between serum titers of anti-Helicobacter pylori (H. pylori) immunoglobulin G (IgG) and hepatitis B virus surface antibody (HBsAb). METHODS Korean adults were included whose samples had positive Giemsa staining on endoscopic biopsy and were studied in the hepatitis B virus surface antigen (HBsAg)/HBsAb serologic assay, pepsinogen (PG) assay, and H. pylori serologic test on the same day. Subjects were excluded if they were positive for HBsAg, had a recent history of medication, or had other medical condition(s). We analyzed the effects of the following factors on serum titers of HBsAb and the anti-H. pylori IgG: Age, density of H. pylori infiltration in biopsy samples, serum concentrations of PG I and PG II, PG I/II ratio, and white blood cell count. RESULTS Of 111 included subjects, 74 (66.7%) exhibited a positive HBsAb finding. The serum anti-H. pylori IgG titer did not correlate with the serum HBsAb titer (P = 0.185); however, it correlated with the degree of H. pylori infiltration on gastric biopsy (P < 0.001) and serum PG II concentration (P = 0.042). According to the density of H. pylori infiltration on gastric biopsy, subjects could be subdivided into those with a marked (median: 3.95, range 0.82-4.00) (P = 0.458), moderate (median: 3.37, range 1.86-4.00), and mild H. pylori infiltrations (median: 2.39, range 0.36-4.00) (P < 0.001). Subjects with a marked H. pylori infiltration on gastric biopsy had the highest serological titer, whereas in subjects with moderate and mild H. pylori infiltrations titers were correspondingly lower (P < 0.001). After the successful eradication, significant decreases of the degree of H. pylori infiltration (P < 0.001), serum anti-H. pylori IgG titer (P < 0.001), and serum concentrations of PG I (P = 0.028) and PG II (P = 0.028) were observed. CONCLUSION The anti-H. pylori IgG assay can be used to estimate the burden of bacteria in immunocompetent hosts with H. pylori infection, regardless

    Lipid and protein oxidation in Longissimus dorsi (LD) and dry-cured loins from pigs with different genetic (pure Iberian (IBP), Iberian female×Duroc male (IB×D) and Duroc female×Iberian male (D×IB)) and feeding backgrounds (free rearing on acorn and pasture (MON), concentrates high in oleic acid and supplemented with 250ppm of vitamin E(HOVE) and control concentrates (CON)) were investigated. Diet influenced the fatty acids profile from PL and α- and γ-tocopherol contents of LD. IBP-MON pigs showed the lowest malonaldehyde (MDA) values at 200min of iron induced muscle oxidation. Dry-cured loins from IBP-HOVE pigs had significantly (p<0.05) higher values of TBARS than those from the other batches. Neither the diet nor crossbreeding affected hexanal counts in dry-cured loins. Protein carbonyl content showed a similar trend to that observed for MDA values in LD, suggesting a protective role of tocopherol against lipid and protein oxidation. The positive and significant correlations between iron induced lipid oxidation in LD (200 min) and carbonyl content in LD and dry-cured loin (R(2): 0.55 and R(2): 0.52, respectively, p<0.01) support the relationship between lipid and protein oxidation.

    Full Text Available We recently reported that a water extract of laurel or turmeric,1,8-cineole enriched fractions, showed hypolipidemic activityin the zebrafish model. Therefore, the present study investigatedthe cineole’s anti-oxidant and anti-inflammatory activitiesin lipoprotein metabolism in vitro and in vivo. Cineolehad inhibitory effects on cupric ion-mediated oxidation of lipoproteinsin general, while simultaneously enhancing ferric ionremoval ability in high-density lipoprotein (HDL. Hypercholesterolemiawas induced in zebrafish using cholesterol-feedingtreatment, 4% cholesterol, for 3 weeks. After feeding with orwithout the addition of cineole, the results revealed that cineolepossessed lipid-lowering and anti-inflammatory activitiesin hypercholesterolemic zebrafish. In addition, serum amyloidA and interleukin-6 levels were lowered and lipid accumulationwas decreased in the liver. Conclusively, 1,8-cineole wasfound to have anti-oxidant activities in lipoprotein metabolismboth in vitro and in vivo with simultaneous reduction of lipidaccumulation in the liver of zebrafish.

    Prebiotic fibres have been proposed to promote weight loss and lower serum cholesterol; however, the mechanisms are not fully understood. The aim of the present research was to identify possible mechanisms through which prebiotic fibres improve serum lipids. Lean and obese JCR:La-cp rats aged 8 weeks consumed one of three diets supplemented with 0, 10 or 20 % prebiotic fibre for 10 weeks. Rats were anaesthetised and a fasting blood sample was taken for lipid analysis. Real-time PCR was used to determine gene expression for cholesterol and fatty acid regulatory genes in liver tissue. Liver and caecal digesta cholesterol and TAG content were quantified. Both doses of prebiotic fibre lowered serum cholesterol levels by 24 % in the obese hyperlipidaemic rats (P < 0.05). This change was associated with an increase in caecal digesta as well as an up-regulation of genes involved in cholesterol synthesis and bile production. Additionally, there was a 42 % reduction in TAG accumulation in the liver of the obese rats with 10 % prebiotic diet (P < 0.05); however, no change in liver fatty acid synthase (FAS). Prebiotic fibres appear to lower cholesterol levels through increased cholesterol excretion in the form of bile and inhibit the accumulation of TAG in the liver through a mechanism unrelated to FAS. These effects appear to be limited to the obese model and particularly the 10 % dose. The present work is significant as it provides insight into the mechanisms of action for prebiotic fibres on lipid metabolism and furthers the development of dietary treatments for hypercholesterolaemia.

    A high-carbohydrate low-fat (HC/LF) diet and lipoprotein lipase gene (LPL) Ser447Stop and Hind III polymorphisms have separately been found to be associated with triacylglycerol (TG) and high density lipoprotein cholesterol (HDL-C). This study sought to test the effects of LPL polymorphisms and an HC/LF diet on the serum lipid profile of Chinese with a lower incidence of coronary artery disease (CAD) consuming a diet with less fat and more carbohydrates. Fifty-six healthy subjects (22.89 ± 1.80 years) were given a control diet of 30.1% fat and 54.1% carbohydrates for 7 days, followed by an HC/LF diet of 13.8% fat and 70.1% carbohydrate for 6 days; there were no changes in the fatty acid composition or restrictions on total energy. Serum lipid profiles at baseline, before and after the HC/LF diet, and LPL polymorphisms were analyzed. After 6 days of the HC/LF diet, TG and the homeostasis model assessment of insulin resistance (HOMAIR) index were found to increase only in females with S447S. No decrease in HDL-C was noted. In subjects with Hind III polymorphism, increased TG was found in all females but not in males. Increased HDL-C, together with apolipoprotein (apo) AI, was found in male H- carriers but not in males with H+/H+ and females. In conclusion, LPL Ser447Stop and Hind III polymorphisms modified the effects of an HC/LF diet on the serum lipid profiles of a young Chinese population in different ways. Effective strategies for dietary interventions targeted at younger populations should take into account the interplay between genetic polymorphisms, diet, and gender.

  18. Environmental risk score as a new tool to examine multi-pollutants in epidemiologic research: an example from the NHANES study using serum lipid levels.

    Directory of Open Access Journals (Sweden)

    Sung Kyun Park

    Full Text Available OBJECTIVE: A growing body of evidence suggests that environmental pollutants, such as heavy metals, persistent organic pollutants and plasticizers play an important role in the development of chronic diseases. Most epidemiologic studies have examined environmental pollutants individually, but in real life, we are exposed to multi-pollutants and pollution mixtures, not single pollutants. Although multi-pollutant approaches have been recognized recently, challenges exist such as how to estimate the risk of adverse health responses from multi-pollutants. We propose an "Environmental Risk Score (ERS" as a new simple tool to examine the risk of exposure to multi-pollutants in epidemiologic research. METHODS AND RESULTS: We examined 134 environmental pollutants in relation to serum lipids (total cholesterol, high-density lipoprotein cholesterol (HDL, low-density lipoprotein cholesterol (LDL and triglycerides using data from the National Health and Nutrition Examination Survey between 1999 and 2006. Using a two-stage approach, stage-1 for discovery (n = 10818 and stage-2 for validation (n = 4615, we identified 13 associated pollutants for total cholesterol, 9 for HDL, 5 for LDL and 27 for triglycerides with adjustment for sociodemographic factors, body mass index and serum nutrient levels. Using the regression coefficients (weights from joint analyses of the combined data and exposure concentrations, ERS were computed as a weighted sum of the pollutant levels. We computed ERS for multiple lipid outcomes examined individually (single-phenotype approach or together (multi-phenotype approach. Although the contributions of ERS to overall risk predictions for lipid outcomes were modest, we found relatively stronger associations between ERS and lipid outcomes than with individual pollutants. The magnitudes of the observed associations for ERS were comparable to or stronger than those for socio-demographic factors or BMI. CONCLUSIONS: This study suggests ERS

    Objective To investigate the effect of body positions on serum lipid parameters. Methods By autogenous contrast and cross match survey, blood samples of 100 volunteers were drawn from the same part in both standing and lying positions. 25 of the volunteers had their blood samples collected respectively after standing and sitting for IS min, lying for 15 min and 30 min and then sitting for another 15 min. The blood samples accompanied with quality control materials were analyzed for eight serum lipid parameters on an automatic biochemical analyzer. Results Setting the lying position as baseline, the eight serum lipid parameters detected in sitting position were significantly higher than those in lying position (P0.05). The average increase rate was 11.71% and the highest increase rate was 22.95%. The parameters showed no correlation with gender. In the 25 volunteers, the parameters increased successively from lying, sitting to standing position. While sitting for 15 min after lying, these parameters returned to 95 % of the original parameters in sitting position. Conclusion Changing body position can result in obvious physiological variation of the eight serum lipid parameters.%目的 探讨不同体位对血脂检测指标的影响.方法 100名志愿者,经同体交叉配对设计,抽取坐、卧位同一部位的血液,其中25名分别抽站15min、坐15min、卧15min、30 min、卧后坐15min标本,在全自动生化分析仪上与质控品同时检测8项血脂指标.结果 以卧位为基线与坐位相比,8项血脂检测结果平均升高11.71%,最高升至22.95%,差异均有统计学意义(P<0.05),且与性别有关.25名志愿者血脂水平从卧位到站位结果逐渐升高,依次为卧位<坐位<站位.卧位后坐15min,各指标可恢复到原坐位的95%以上.结论 体位改变能引起血脂检测指标的显著差异.

    2015-02-01

    Conclusions: The study findings revealed that in both groups of obese and lean men, serum levels of IL-18 positively correlated with insulin resistance and triglyceride, and negatively correlated with high-density lipoprotein. Furthermore, within obese individuals that have elevated IL-18 levels, this can be associated with disorder in glycemic control and lipid profile, and thus, with increased risk of cardiovascular and metabolic disorders. IL-18 levels do not appear to have any correlations with acylated ghrelin, growth hormone, total cholesterol, and low-density lipoprotein.

    Objective:To explore the relationship between levels of blood glucose, blood lipid and serum cystatin C and lower-extremity arterial disease in type 2 diabetic mellitus so as to provide the basis for the prevention and treatment of the disease.Methods:A total of 240 cases of patients with type 2 diabetic mellitus receiving physical examinations in our hospital from March 2014 to March 2015 were selected and divided into three groups. The control group was consisted of type 2 diabetes patients without lower-extremity arterial disease, the observation group 1 included type 2 diabetes patients with mild or moderate lower-extremity arterial disease, and the observation group 2 was formed by type 2 diabetes patients with severe lower-extremity arterial disease. Each group contained 80 cases. Then, the heights, weights, waist and hip circumferences of patients in the three groups were determined and the body mass index (BMI) and waist to hip ratio (WHR) were calculated; the fasting blood glucose (FBG), fasting insulin (FINS), insulin resistance index (HOMA-IR), 2 h postprandial blood glucose (2 h PG) and glycosylated hemoglobin (HBA1c) in two groups were detected; and the levels of serum total cholesterol(TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (apoA1), apolipoprotein B (apoB) and cystatin C (CysC) in two groups were also tested.Results:Compared with the control group, the WHR, FBG, HOMA-IR, 2 h PG, HBA1c, LDL-C, apoB and CysC all increased significantly, and the differences were statistically significant. Besides, there were statistically significances existing between the observation groups 1 and 2. What’s more, the serum levels of TC, HDL-C, TG and apoA1 in the observation groups were not significantly different from those of the control group.Conclusions: There is a close relationship between blood glucose, blood lipid, serum cystatin C level and lower-extremity arterial

    World Health Organization is concerned for parental vitamin deficiency and its effect on offspring health. This study examines the effect of a marginally dietary-induced parental one carbon (1-C) micronutrient deficiency on embryonic gene expression using zebrafish. Metabolic profiling revealed a reduced 1-C cycle efficiency in F0 generation. Parental deficiency reduced the fecundity and a total of 364 genes were differentially expressed in the F1 embryos. The upregulated genes (53%) in the deficient group were enriched in biological processes such as immune response and blood coagulation. Several genes encoding enzymes essential for the 1-C cycle and for lipid transport (especially apolipoproteins) were aberrantly expressed. We show that a parental diet deficient in micronutrients disturbs the expression in descendant embryos of genes associated with overall health, and result in inherited aberrations in the 1-C cycle and lipid metabolism. This emphasises the importance of parental micronutrient status for the health of the offspring.

    The oxidation of polyunsaturated fatty acids to the corresponding hydroperoxide by plant and animal lipoxygenases is an important step for the generation of bioactive lipid mediators. Thereby fatty acid hydroperoxide represent a common intermediate, also in human innate immune cells, like neutrophil granulocytes. In these cells a further key component is the heme protein myeloperoxidase producing HOCl as a reactive oxidant. On the basis of different investigation a reaction of the fatty ac...

    Fatty acids containing stearic acid, which are found in hydrogenated fat, may have a detrimental effect on the cholesterol and triacylglycerol (TAG) content of plasma lipoproteins, and on the absorption of fatty acids and fat-soluble vitamins. The aim of our study was to examine the tissue concentration of lipids and vitamins A and E after feeding a hydrogenated soybean oil (HSO) diet to rats. Twenty male Sprague-Dawley rats were randomly divided into two groups, fed on coconut oil (control) and HSO, respectively in amounts corresponding to 15% of the total feed. Plasma total cholesterol, VLDL- and LDL-cholesterol, lipid peroxidation and daily excretion of the TAG and cholesterol in feces were higher in the HSO than in the control group. TAG values in plasma and liver, and HDL-cholesterol levels in plasma were lower in the HSO than in the control group. The same was true for phospholipids in plasma and for saturated fatty acids, mono- and polyunsaturated fatty acids levels in the liver and vitamin E in plasma, LDL and adipose tissue. The results of this study provide new evidence concerning the effect of dietary hydrogenated fat on lipid, TAG and vitamin E status, which are important for maintenance of good health. Consumption of dietary HSO may be associated with cardiovascular disease.

    Organohalogen compounds constitute one of the important groups of persistent organic pollutants (POPs). Among them, due to their long-term health effects, one should pay attention on organochlorine pesticides, polychlorinated biphenyls (PCBs) and perfluoroalkylated substances (PFASs). This paper is an attempt to answer the question about relation between the fact of cohabitation by couples expecting a child and the level of the organohalogen compounds in the blood serum of both parents. The study was done on a population of parent couples from Greenland, Poland and Ukraine, from whom blood samples were collected in order to establish the levels of marker organohalogen compounds. We selected, as the representative of these compounds, the most persistent metabolite of DDT, i.e. p,p'-DDE, the most frequently detected PCB congener - CB-153, and PFOS and PFOA as the representatives of PFASs. The results show that in case of all compounds under study the highest concentrations were present always in men in relation to the levels detected in the blood serum of their female partners, regardless of the country of origin of the couple. A positive correlation was noted between the concentrations of the studied compounds in the blood serum of men and women in parenting couples. In some cases these correlations were statistically significant, e.g. for concentrations of p,p'-DDE in pairs from Greenland and Ukraine, of CB-153 in pairs from Poland and Ukraine, and of PFOS for parents from Greenland and Poland, while for PFOA - only for couples from Greenland. The concentrations of the compounds included in the study were similar to the levels found in general population in other countries. Our results show that the exposure to POPs resulting from cohabitation plays a role in the general exposure to these compounds.

  11. Relationship of serum lipids to adrenal-gland uptake of 6β-[131I] iodomethyl-19-norcholesterol in Cushing's syndrome

    International Nuclear Information System (INIS)

    An alteration in serum cholesterol levels has been suggested as a possible modifier of adrenal uptake of the cholesterol analog, 6β-[131I]iodomethyl-19-norcholesterol (NP-59). To assess the effect of hypercholesterolemia upon NP-59 adrenal uptake, patients with Cushing's syndrome (eight with pituitary-dependent, four with ACTH-independent, and two with ectopic-ACTH syndrome) were selected for retrospective analysis based on the availability of serum cholesterol (n = 14) and triglyceride (n = 10) concentrations obtained at the time of adrenal scintigraphy. A negative correlation (r = -0.78, p < 0.01) was found between NP-59 uptake and serum cholesterol levels in patients with pituitary-dependent Cushing's disease. Compared with pituitary-dependent disease, the ectopic-ACTH syndrome and ACTH-independent states demonstrated equal or greater adrenal uptake of NP-59 at similar serum cholesterol concentrations. Serum triglyceride concentrations did not correlate with total adrenal uptake of NP-59 in any of the patient groups studied. Increased serum cholesterol concentrations are associated with diminished adrenal uptake of NP-59, and in some cases may limit the diagnoic efficacy of adrenal scintigraphy in Cushing's syndrome

    Food formulation with bioactive ingredients is a potential strategy to promote satiety and weight management. Whey proteins are high in leucine and are shown to decrease hunger ratings and increase satiety hormone levels; cocoa polyphenolics moderate glucose levels and slow digestion. This study examined the effects of cocoa and whey proteins on lipid and glucose metabolism and satiety in vitro and in a clinical trial. In vitro, 3T3-L1 preadipocytes were treated with 0.5-100 μg/mL cocoa polyphenolic extract (CPE) and/or 1-15 mM leucine (Leu) and assayed for lipid accumulation and leptin production. In vivo, a 6-week clinical trial consisted of nine panelists (age: 22.6 ± 1.7; BMI: 22.3 ± 2.1) consuming chocolate-protein beverages once per week, including placebo, whey protein isolate (WPI), low polyphenolic cocoa (LP), high polyphenolic cocoa (HP), LP-WPI, and HP-WPI. Measurements included blood glucose and adiponectin levels, and hunger ratings at baseline and 0.5-4.0 h following beverage consumption. At levels of 50 and 100 μg/mL, CPE significantly inhibited preadipocyte lipid accumulation by 35% and 50%, respectively, and by 22% and 36% when combined with 15 mM Leu. Leu treatment increased adipocyte leptin production by 26-37%. In the clinical trial, all beverages significantly moderated blood glucose levels 30 min postconsumption. WPI beverages elicited lowest peak glucose levels and HP levels were significantly lower than LP. The WPI and HP beverage treatments significantly increased adiponectin levels, but elicited no significant changes in hunger ratings. These trends suggest that combinations of WPI and cocoa polyphenols may improve markers of metabolic syndrome and satiety. PMID:26987021

    Objective To determine the effects of raloxifene hydrochloride (RLX) on bone mineral density (BMD), bone metabolism markers and serum lipids in healthy postmenopausal women in Beijing.Methods A multicenter, randomized, double-blind, placebo-controlled study was conducted in a total of 204 healthy postmenopausal women (age 59.5±5.0 years and weight 62.8±8.7 kg) treated with either RLX 60 mg (n=102) or placebo (n=102) daily for 12 months. BMD, serum lipids, and bone markers were measured before and after drug administration.Results Compared with placebo, RLX produced a significant increase in both total lumbar spine and total hip BMD. For the lumbar spine, percentage increase in total BMD was 2.3% with RLX compared with a decrease of 0.1% with placebo (P<0.001). Corresponding values for total hip BMD were a 2.5% increase for RLX and a 1.1% increase for placebo (P=0.011). For biochemical markers of bone metabolism, serum osteocalcin and C-telopeptide, percentage decreases were 27.65% and 24.02% in RLX-treated subjects. Corresponding values in placebo were a 10.64% decrease and a 15.75% increase (RLX compared with placebo, both P<0.001). For total cholesterol and low-density lipoprotein cholesterol levels, percentage decreases were 6.44% and 34.58% in the RLX-treated group. Corresponding values in placebo-treated patients were a 1.44% increase and a 19.07% decrease (RLX compared with placebo, both P<0.001). No differences were found for high-density lipoprotein cholesterol or triglyceride levels between the two groups. Only 5 subjects discontinued early owing to an adverse event (3 in the RLX group and 2 in the placebo group). Conclusions This study confirms that RLX exerts positive effects on the skeleton, increasing BMD and decreasing biochemical markers of bone metabolism, and has a positive effect on the overall serum lipid profile in postmenopausal women in China.

    Objective: To observe the effect of Gengnianchun Recipe (更年春方, GNC) on bone mineral density (BMD), bone biomechanical parameters and serum lipid level in the bilaterally ovariectomized (OVX) rats and to explore the prophylactic and therapeutic action of GNC on ovariectomy induced osteoporosis and hyperlipidemia. Methods: OVX SD rats, 10- 12 months old, were divided into different groups and fed with GNC 2 g/d, GNC 1 g/d and Nilestriol 0. 125 mg/week, respectively for 4 months to observe the change of BMD and bone biomechanical parameters of the lumbar vertebrae, and the serum levels of total cholesterol (TC), triglyceride(TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), and to compare the effect of the two drugs on the morphology of the uterus. Results:There was marked reduction in BMD and biomechanical parameters in lumbar vertebrae ( P<0.01 ) and increase of serum TC and LDL-C levels ( P<0.01 ) in rats after OVX. GNC or Nilestriol significantly improved the decreased BMD and biomechanical parameters of the lumbar vertebrae (P<0.05 or P<0.01), and reduced the serum TC and LDL-C levels (P<0.01). In the Nilestriol group, the wet weight of uterus got increased obviously ( P<0.01 ), the number of uterine glands increased, uterine columnar epithelium thickened, and the mitotic figures in the epithelial stroma and myointimal cells augmented. But no such effect in wet weight and morphology of uterus was found in the GNC group. Conclusion: GNC could increase the BMD and biomechanical parameters of the lumbar vertebrae, reduce the serum TC and LDL-C levels, yet produce no adverse reaction in stimulating proliferation and hypertrophy of uterus.

    The metabolic effects induced by feed contaminated with a lower or a higher concentration of -nonylpnenol (NP), 4-tert-octylphenol (t-OP) or bisphenol A (BPA), three environmental endocrine disruptors, were assessed in juvenile sea bream liver. Histological analysis demonstrated that all these three xenobiotics induced hepatic lipid accumulation and steatosis. These findings prompted analysis of the expression of the major molecules involved in lipid metabolism: peroxisome proliferator activated receptors (which is encoded by ppars), fatty acid synthase (encoded by fas), lipoprotein lipase (encoded by lpl) and hormone-sensitive lipase (encoded by hsl). The enzymes encoded by ppars and fas are in fact responsible for lipid accumulation, whereas lpl- and hsl- encoded proteins play a pivotal role in fat mobilization. The three xenobiotics modulated ppar mRNA expression: pparα mRNA expression was induced by the higher dose of each contaminant; pparβ mRNA expression was upregulated by the lower doses and in BPA2 fish ppary mRNA overexpression was induced by all pollutants. These data agreed with the lipid accumulation profiles documented by histology. Fas mRNA levels were modulated by the two NP doses and the higher BPA concentration. Lpl mRNA was significantly upregulated in all experimental groups except for BPA1 fish while hsl mRNA was significantly downregulated in all groups except for t-OP2 and BPA1 fish. The plasma concentrations of cortisol, the primary stress biomarker, were correlated with the levels of pepck mRNA level. This gene encodes phosphoenolpyruvate carboxykinase which is one of the key enzymes of gluconeogenesis. Pepck mRNA was significantly overexpressed in fish exposed to NP2 and both t-OP doses. Finally, the genes encoding cyclooxygenase 2 (cox2) and 5-lipoxygenase (5 lox), the products of which are involved in the inflammatory response, transcriptions were significantly upregulated in NP and BPA fish, whereas they were unchanged in t

    Full Text Available We have previously reported that the supplementation of ganglioside-enriched complex-milk-lipids improves cognitive function and that a phospholipid-enriched complex-milk-lipid prevents age-related cognitive decline in rats. This current study evaluated the effects of post-natal supplementation of ganglioside- and phospholipid-enriched complex-milk-lipids beta serum concentrate (BSC on cognitive function in young rats. The diet of male rats was supplemented with either gels formulated BSC (n = 16 or blank gels (n = 16 from post-natal day 10 to day 70. Memory and anxiety-like behaviors were evaluated using the Morris water maze, dark–light boxes, and elevated plus maze tests. Neuroplasticity and white matter were measured using immunohistochemical staining. The overall performance in seven-day acquisition trials was similar between the groups. Compared with the control group, BSC supplementation reduced the latency to the platform during day one of the acquisition tests. Supplementation improved memory by showing reduced latency and improved path efficiency to the platform quadrant, and smaller initial heading error from the platform zone. Supplemented rats showed an increase in striatal dopamine terminals and hippocampal glutamate receptors. Thus BSC supplementation during post-natal brain development improved learning and memory, independent from anxiety. The moderately enhanced neuroplasticity in dopamine and glutamate may be biological changes underlying the improved cognitive function.

    Full Text Available The present study was conducted to evaluate the effect of soybean seeds administration alone or combined with either insulin or glibenclamide on serum lipid profiles in diabetic rats. Male Wister rats were induced diabetes by a single subcutaneous injection of alloxan 100 mg/kg.b.w.The rats randomly divided into six groups (eight rats in each group: The first group served as a control, the second group was administered soybean seed 400 mg/kg.b.w orally as suspension, the third group injected insulin 10 I.U/kg.b.w, subcutaneously, the fifth group administered glibenclamide 5 mg/kg.b.w. orally. Accompaniment of soybean seeds with either of insulin or glibenclamide given the fourth and sixth groups, using the same routes and doses in the individual groups. All treatments were once daily for two weeks. Soybean seeds treatment alone resulted in an improvement of body weight and decrease of triglyceride and total lipids levels. While treatment with insulin or glibenclamide as alone or combination with soybean seeds showed a significant reduction in the levels of total cholesterol, triglyceride, low density lipoprotein, and total lipids, beside a significant increase in both body weight and high density lipoprotein. Beneficial effects were seen when soybean seeds combined with either of insulin or glibenclamide treatment. These results indicate the usefulness of soybean seeds in the management of diabetes through the hypolipidemic effects of soybean seeds in diabetic rats.

    Objective The aim of our study was to investigate the relationship among age, sex, body mass index (BMI), serum lipid profiles, blood glucose (BG), and bone mineral density (BMD), making an assessment of the risk of osteoporosis. Materials and methods A total of 1,035 male and 3,953 female healthy volunteers (aged 41–95 years) were recruited by an open invitation. The basic information, including age, sex, height, weight, waistline, hipline, menstrual cycle, and medical history, were collected by a questionnaire survey and physical examination. Serum lipid profiles, BG, postprandial blood glucose, and glycosylated hemoglobin were obtained after 12 hours fasting. BMD in lumbar spine was measured by dual-energy X-ray absorptiometry scanning. Results The age-adjusted BMD in females was significantly lower than in males. With aging, greater differences of BMD distribution exist in elderly females than in males (P7.0 mmol/L was lower than in people with BG of ≤7.0 mmol/L (P<0.001). People with serum high-density lipoprotein cholesterol levels of ≥1.56 mmol/L had a greater prevalence of osteoporosis compared with high-density lipoprotein cholesterol ≤1.55 mmol/L. Logistic regression with odds ratios showed that no association was found among total cholesterol, triglyceride, low-density lipoprotein cholesterol, glycosylated hemoglobin, postprandial blood glucose and BMD. Conclusion The present study further confirmed that factors such as age, sex, weight, BMI, high-density lipoprotein cholesterol, and diabetes are significant predictors of osteoporosis in the Chinese people.

    Full Text Available Background: Dyslipidemia is considered as one of the crucial contributors to cardio- cerebro-vascular diseases. Objectives: The present study aimed to compare the effects of Rice Barn Oil (RBO, Grape Seed Oil (GSO, and Canola Oil (CO on dyslipidemia and oxidative stress in experimentally induced hyperlipidemic rats. Materials and Methods: In the present experimental study, forty hyperlipidemic male Wistar rats were randomly assigned to 4 groups to receive RBO, GSO, or CO or Soy Bean Oil (SBO, as controls, for 4 weeks following a 3-week period of Atherogenic Diet (AD intake. Blood samples were collected at the beginning of the study, after inducing dyslipidemia, and at the end of the experimental period. Then, the data were entered into the SPSS statistical software (v. 13.0 and analyzed using paired t-test, paired sample Wilcoxon signed rank test, and Kruskal-Wallis test. Results: AD elevated lipid and/or lipoprotein profile and decreased the paraoxonase activity in the hyperlipidemic rats. The results of paired t-test revealed that RBO led to a significant improvement in serum lipoprotein profile and paraoxonase activity. Besides, a significant difference was found in the GSO group regarding all the measured parameters, except for paraoxonase activity. Moreover, CO diet showed a significant hypolipidemic effect on serum Triglyceride (TG and Total Cholesterol (TC and led to a slight improvement in Low Density Lipoprotein-Cholesterol (LDL-C and High Density Lipoprotein-Cholesterol (HDL-C. Conclusions: The results of the present study suggested that vegetable oils, including RBO, GSO, and CO, might improve dyslipidemia and oxidative stress in hyperlipidemic rats. Indeed, substituting saturated fatty acids with unsaturated fatty acids in rats’ diet had beneficial effects on serum lipid profile and oxidative stress. Comparison of the 3 edible oils showed that GSO had a more profound effect on decreasing hyperlipidemia.

    Fatty acids, which are the major cardiac fuel, are derived from lipid droplets stored in cardiomyocytes, among other sources. The heart expresses hormone-sensitive lipase (HSL), which regulates triglycerides (TG) breakdown, and the enzyme is under hormonal control. Evidence obtained from adipose...... tissue suggests that testosterone regulates HSL activity. To test whether this is also true in the heart, we measured HSL activity in the left ventricle of sedentary male rats that had been treated with testosterone supplementation or orchidectomy with or without testosterone substitution. Left ventricle...... HSL activity against TG was significantly elevated in intact rats supplemented with testosterone. HSL activity against both TG and diacylglyceride was reduced by orchidectomy, whereas testosterone replacement fully reversed this effect. Moreover, testosterone increased left ventricle free fatty acid...

    Effects of chronic exposures (one and two months) to sublethal doses of hexavalent chromium (2 and 4 mg/L potassium dichromate) on organ histopathology and serum cortisol profile were investigated and their overall impact on growth and behavior of a teleost fish, Channa punctatus was elucidated. Histopathological lesions were distinct in the vital organs gill, kidney and liver. The gill lamellae became lifted, fused, and showed oedema. Hyperplasia and hypertrophy of lamellar epithelial cells were distinct with desquamation. Hypertrophy of epithelial cells of renal tubules and reduction in tubular lumens were observed in the trunk kidney. The atrophy of the head kidney interrenal cells and decreased serum cortisol level indicated exhaustion of interrenal activity. Hepatocyte vacuolization and shrinkage, nuclear pyknosis and increase of sinusoidal spaces were observed in the liver. Abnormal behavioral patterns and reduced growth rate were also noticed in the exposed fish. The chronic hexavalent chromium exposure thus by affecting histopathology of gill, kidney (including interrenal tissue) and liver could impair the vital functions of respiration, excretion, metabolic regulation and maintenance of stress homeostasis which in the long-run may pose serious threat to fish health and affect their population.

    Background Raloxifene has been approved for prevention and treatment of postmenopausal osteoporosis in Caucasian women. It also has some positive effects on serum lipids in Caucasians. The objective of this study was to determine the effect of raloxifene hydrochloride on lumbar spine and total hip bone mineral density (BMD), bone metabolism, and serum lipids in Chinese postmenopausal women with osteoporosis.Methods This was a multi-center, randomized, double-blind, placebo-controlled clinical trial in which 204 postmenopausal Chinese women with osteoporosis were assigned to receive raloxifene (60 mg) or placebo treatment daily for 12 months. BMD, serum bone metabolism markers, and serum lipids were measured before and after drug administration. BMD was measured by Dual-Energy X-Ray Absorptiometry (DEXA) and bone metabolism markers were analyzed by one-step enzyme-linked immunosorbent assay. Serum lipids were measured by enzymatic analysis.Results At the end of the 12-month study, lumbar spine BMD increased in both groups with a mean increase of (3.3±4.8) % in the raloxifene group and (1.0±4.9) % in the placebo group (P0.05). In the raloxifene group, the median decreases in the biochemical markers of bone metabolism serum osteocalcin and C-telopeptide were 41.7% and 61.5%, respectively. These changes were statistically significant compared with those in the placebo group (10.6% and 35.6%, P<0.001, respectively). Both total cholesterol and low-density lipoprotein cholesterol decreased significantly in the raloxifene group compared with those in the placebo group (P<0.001, respectively) and there was no significant effect of raloxifene on high-density lipoprotein cholesterol and triglycerides compared with placebo. Conclusions Raloxifene 60 mg/d for 12 months significantly increases lumbar spine and total hip BMD, significantly decreases bone turnover, and has favourable effects on serum lipids in Chinese postmenopausal women with osteoporosis.

    Background Estrogen might play an important role in type 2 diabetes mellitus pathogenesis. A number of polymorphisms have been reported in the estrogen receptor alpha (ERα) gene (also named ESR1), including the XbaI and PvuⅡ restriction enzyme polymorphisms of ESR1, which may be involved in disease pathogenesis. The aim of this study was to determine whether ERα gene polymorphisms are associated with type 2 diabetes mellitus and serum lipid level.Methods Two hundred and ninety-nine patients with type 2 diabetes mellitus were compared with three hundred and forty-one health controls of Guangzhou in China, both were male and postmenopausal female residents at 51-70 years. ESR1 genotyping was performed using polymerase chain reaction (PCR) and PvuⅡ and XbaI restriction fragment length polymorphism (PCR-RFLP) analysis.Results ESR1 allelic frequencies of P, p and X, x alleles were 0.408, 0.592; 0.360, 0.640 in the type 2 diabetes mellitus group and 0.318, 0.682; 0.328, 0.672 in the control group, respectively. In case-control study, there was significant difference in PvuⅡ, but not XbaI, allele frequency between the type 2 diabetes mellitus and control groups (P=0.001 and P=0.122). When the group was separated into men and women, the difference was significant in women (P<0.001) but not in men (P=0.854) with the PvuⅡ genotype, and the effect of PvuⅡ variant on the development of type 2 diabetes mellitus was improved with aging. In addition, PvuⅡ genotype was associated with blood glucose [fasting blood glucose (FBG), postprandial blood glucose (PBG)] and serum lipid [total cholesterol (TC) and low density lipoprotein (LDL)-c] concentration in healthy women.Conclusions PvuⅡ polymorphism of ESR1 increases susceptibility to type 2 diabetes mellitus in Chinese Guangzhou women. ESR1 variants may also impact serum lipid metabolism, which might provide a mechanism connecting ESR1 to type 2 diabetes.

    Inulin, a group of dietary fibers, is reported to improve the metabolic disorders. In the present study, we investigated the effects of chicory inulin on serum metabolites of uric acid (UA), lipids, glucose, and abdominal fat deposition in quail model induced by a purine-rich diet. In this study, 60 male French quails were randomly allocated to five groups: CON (control group), MOD (model group), BEN (benzbromarone-treated group), CHI-H (high-dosage chicory inulin-treated group), and CHI-L (low-dosage chicory inulin-treated group). The serum UA level was significantly increased in the model group from days 7 to 28, as well as triglyceride (TG) and free fatty acid (FFA) increased later in the experimental period. The abdominal fat ratio was increased on day 28. Benzbromarone can decrease UA levels on days 14 and 28. The high and low dosage of chicory inulin also decreased serum UA levels on days 7, 14, and 28. The abdominal fat ratio, activity, and protein of acetyl-CoA carboxylase (ACC) were decreased in chicory inulin-treated groups. The activities of xanthine oxidase (XOD) and fatty acid synthase (FAS) were increased in the model group and decreased in the benzbromarone and chicory inulin groups. This study evaluated a quail model of induced hyperuricemia with other metabolic disorders caused by a high-purine diet. The results indicated that a purine-rich diet might contribute to the development of hyperuricemia, hypertriglyceridemia, and abdominal obesity. Chicory inulin decreased serum UA, TG, and abdominal fat deposition in a quail model of hyperuricemia by altering the ACC protein expression and FAS and XOD activities.

    Full Text Available Abstract Background We explored the associations of three variants in the uncoupling protein 2 (UCP2 gene, one variant in the UCP2-UCP3 intergenic region and five variants in the uncoupling protein 3 (UCP3 gene with obesity and diabetes related traits in subjects with impaired glucose tolerance participating in Finnish Diabetes Prevention Study. Altogether 507 overweight individuals (body mass index: 31.2 ± 4.5 kg/m2, age: 55 ± 7 years for whom DNA was available were randomized to either an intensified diet and physical activity group or to a conventional care control group. Methods We analysed the data from the baseline and annual follow-up visits from years 1, 2 and 3. Measurements of anthropometry, plasma glucose and serum insulin in oral glucose tolerance test, serum total cholesterol, HDL-cholesterol and triglycerides were included. The median follow-up time for type 2 diabetes incidence was 7 years. Genetic variants were screened by restriction fragment length polymorphism or Illumina method. Results UCP3 gene variant rs3781907 was associated with increased serum total and LDL-cholesterol levels, at baseline and during the follow-up period. The same variant was associated with a higher risk of type 2 diabetes. Variants rs1726745, rs11235972 and rs1800849 in the UCP3 gene associated with serum total and LDL-cholesterol at baseline. Haploblock including variants rs659366, rs653529, rs15763, and rs1726745 was associated with measures of abdominal obesity at baseline and in the longitudinal analysis. The haplotype comprising alleles rs659366-G, rs653529-A, rs15763-G and rs1726745-A was associated with higher waist-to-hip ratio, and haplotype comprising alleles rs3781907-G, rs11235972-A, and rs1800849-T was associated with increased serum total and LDL-cholesterol concentrations. Conclusion Genetic variation in the UCP2-UCP3 gene cluster may act as a modifier increasing serum lipid levels and indices of abdominal obesity, and may thereby also

    Nutrition of non-natives in the Far North is of European character but also has the features of native population national cuisine. Because of these factors, there are some peculiarities in formation of blood lipid spectrum in non-natives. In particular, in population of non-native women of Yamalo-Nenets Autonomous Okrug, the fat component of 24-hour diet influenced most, carbohydrate component had less importance.

    2010-01-01

    Full Text Available Psoriasis is a common disease with the population prevalence ranging from 2% to 3%. Its prevalence in the population is affected by genetic, environmental, viral, infectious, immunological, biochemical, endocrinological, and psychological factors, as well as alcohol and drug abuse. In the recent years, psoriasis has been recognised as a systemic disease associated with numerous multiorgan abnormalities and complications. Dyslipidemia is one of comorbidities in psoriatic patients. Lipid metabolism studies in psoriasis have been started at the beginning of the 20th century and are concentrated on skin surface lipids, stratum corneum lipids and epidermal phospholipids, serum lipids, dermal low-density lipoproteins in the psoriatic skin, lipid metabolism, oxidative stress and correlations between inflammatory parameters, lipid parameters and clinical symptoms of the disease. On the basis of the literature data, psoriasis can be described as an immunometabolic disease.

    Full Text Available Abstract Background The metabolic syndrome, known also as the insulin resistance syndrome, refers to the clustering of several risk factors for atherosclerotic cardiovascular disease. Dyslipidaemia is a hallmark of the syndrome and is associated with a whole body reduction in the activity of lipoprotein lipase (LPL, an enzyme under the regulation of the class of nuclear receptors known as peroxisome proliferator-activated receptor (PPAR. Glycyrrhizic acid (GA, a triterpenoid saponin, is the primary bioactive constituent of the roots of the shrub Glycyrrhiza glabra. Studies have indicated that triterpenoids could act as PPAR agonists and GA is therefore postulated to restore LPL expression in the insulin resistant state. Results Oral administration of 100 mg/kg of GA to high-fat diet-induced obese rats for 28 days led to significant reduction in blood glucose concentration and improvement in insulin sensitivity as indicated by the homeostasis model assessment of insulin resistance (HOMA-IR (p Conclusion In conclusion, GA may be a potential compound in improving dyslipidaemia by selectively inducing LPL expression in non-hepatic tissues. Such up-regulation was accompanied by a GA-mediated improvement in insulin sensitivity, which may be associated with a decrease in tissue lipid deposition. The HDL-raising effect of GA suggests the antiatherosclerotic properties of GA.

    Diabetes is known to involve oxidative stress and changes in lipid metabolism. Many secondary plant metabolites have been shown to possess antioxidant activities, improving the effects of oxidative stress on diabetes. This study evaluated the effects of extracts from Gongronema latifolium leaves on antioxidant enzymes and lipid profile in a rat model of non insulin dependent diabetes mellitus (NIDDM). The results confirmed that the untreated diabetic rats were subjected to oxidative stress as indicated by significantly abnormal activities of their scavenging enzymes (low superoxide dismutase and glutathione peroxide activities), compared to treated diabetic rats, and in the extent of lipid peroxidation (high malondialdehyde levels) present in the hepatocytes. The ethanolic extract of G. latifolium leaves possessed antioxidant activity as shown by increased superoxide dismutase and glutathione peroxidase activities and decreases in malondialdehyde levels. High levels of triglycerides and total cholesterol, which are typical of the diabetic condition, were also found in our rat models of diabetes. The ethanolic extract also significantly decreased triglyceride levels and normalized total cholesterol concentration.

    The effect of an once-a-month injectable contraceptive ( Norethisterone enanthate 50mg plas estradiol valerate 5mg ) on lipids metabolism was evaluated in 22 Chinese women. Other 20 women served as control group. Fasting blood samples were taken at the pre-treatment cycle, the cycles afier first, third, sixth and twelfth month during one year treatment and one post-treatment cycle. The changes of the total cholesterol, total triglycerides, HDL-cholesterol and LDL-cholesterol and the ratio of HDL-C / LDL-C were observed. The results showed that the total cholesterol at the 1st and 3rd month of treatment was significantly decreased (P< 0.01) as comparedwith that of pretreatment value and control group. The HDL-cholesterol and totaltriglycerides were also significantly decreased ( P< 0.05) from the 1st to 12th treatment cycle. After discontinuation, total cholesterol, total triglycerides and HDL-cholesterol recovered to the pretreatment levels. The LDL-cholesterol remained unchanged during the whole course. This study suggests that the monthiy injectable contraceptive induces the change in lipid metabolism without significant changes for HDL-C / LDL-C ratio. Although the lipids level occurred to change in the treatment cycle, it recovered quickly at discontinuation of injection. These alterations may be contributed to the functionof body regulation. It can be concluded that there is no obvious relationship between NET-OEN plus EV and CVD.

    We study how zwitterionic and anionic biomembrane models interact with neurotransmitters (NTs) and anesthetics (ATs) in the presence of Ca(2+) and different pH conditions. As NTs we used acetylcholine (ACh), γ-aminobutyric acid (GABA), and l-glutamic acid (LGlu). As ATs, tetracaine (TC), and pentobarbital (PB) were employed. By using differential scanning calorimetry (DSC), we analyzed the changes such molecules produce in the thermal properties of the membranes. We found that calcium and pH play important roles in the interactions of NTs and ATs with the anionic lipid membranes. Changes in pH promote deprotonation of the phosphate groups in anionic phospholipids inducing electrostatic interactions between them and NTs; but if Ca(2+) ions are in the system, these act as bridges. Such interactions impact the physical properties of the membranes in a similar manner that anesthetics do. Beyond the usual biochemical approach, we claim that these effects should be taken into account to understand the excitatory-inhibitory orchestrated balance in the nervous system. PMID:27362370

    BACKGROUND/OBJECTIVES Evidence indicates that berry anthocyanins are anti-atherogenic, antioxidant, and anti-inflammatory. However, berries differ vastly in their anthocyanin composition and thus potentially in their biological and metabolic effects. The present study compared hypolipidemic, antioxidant, and anti-inflammatory properties of blueberry (BB), blackberry (BK), and blackcurrant (BC) in a diet-induced obesity (DIO) mouse model. MATERIALS/METHODS Male C57BL/6J mice were fed a high fat (HF; 35% fat, w/w) control diet or a HF diet supplemented with freeze-dried 5% BB, 6.3% BK or 5.7% BC for 12 weeks (10 mice/group) to achieve the same total anthocyanin content in each diet. Plasma lipids, antioxidant status and pro-inflammatory cytokines were measured. The expression of genes involved in antioxidant defense, inflammation, and lipid metabolism was determined in the liver, epididymal adipose tissue, proximal intestine, and skeletal muscle. Histological analysis was performed to identify crown-like structure (CLS) in epididymal fat pads to determine macrophage infiltration. RESULTS No differences were noted between the control and any berry-fed groups in plasma levels of liver enzymes, insulin, glucose, ferric reducing antioxidant power, superoxide dismutase, and tumor necrosis factor α. However, BK significantly lowered plasma triglyceride compared with the HF control and other berries, whereas BC significantly reduced F4/80 mRNA and the number of CLS in the epididymal fat pad, indicative of less macrophage infiltration. CONCLUSIONS The present study provides evidence that BB, BK and BC with varying anthocyanin composition differentially affect plasma lipids and adipose macrophage infiltration in DIO mice, but with no differences in their antioxidant capacity and anti-inflammatory potential.

    Objective: To study the effect of ethanolic extract from Alpinia calcarata rhizomes on the serum lipid and leptin levels of rats with hyperlipidemia induced by high-fat diet. Methods: Male wistar rats were divided into six groups: normal, high-fat diet control (HFD) and ethanolic extract of Alpinia calcarata rhizomes (ACRE) (100, 200 and 300 mg/kg; p.o.) was administered to the high fat-diet-induced hyperlipidemic rats for 30 days to evaluate its antihyperlipidemic activity. Atorvastatin (10 mg/kg; p.o.) was used as a standard drug. Results: The results demonstrated that in HFD-induced hyperlipidemic rat, ACRE reduced rat weight gain, triglyceride (TG), total cholesterol levels (TC), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), total protein (TP) and leptin level (pg/mL). Conclusions: These encouraging findings suggest that ACRE has excellent pharmacological potential to prevent hyperlipidemia.

    Full Text Available Introduction: Lupus erythematosus is a chronic, inflammatory autoimmune disease that can affect multiple organs. Lupus can affect many parts of the body, especially in systemic lupus erythematosus (SLE; affected tissues may include the joints, skin, kidneys, heart, lungs, blood vessels, and brain. Case report: A 46-year-old female presented with pruritus, photosensitivity and edema of the cheeks of about 2 years duration, and was evaluated by a dermatologist. On examination, multiple telangiectasias were present on the cheeks, with erythema, edema and a malar rash observed. A review of systems documented breathing difficulty and pleuitic pain, joint pain and joint edema, photosensitivity, cardiac dysrhythmia, and periodic pain in the back close to the kidneys. Methods: Skin biopsies for hematoxylin and eosin testing, as well for direct and indirect immunofluorescence were performed, in addition to multiple diagnostic blood tests, chest radiography and directed immunologic testing. Results: The blood testing showed elevated C-reactive protein. Direct and indirect immunofluorescence testing utilizing monkey esophagus, mouse and pig heart and kidney, normal human eyelid skin and veal brain demonstrated strong reactivity to several components of smooth muscle, nerves, blood vessels, skin basement membrane zone and sweat gland ducts and skin meibomian glands. Anti-endomysium antibodies were detected as well as others, especially using FITC conjugated Complement/C1q, FITC conjugated anti-human immunoglobulin IgG and FITC conjugated anti-human fibrinogen. Conclusions: We conclude that both direct and indirect immunofluorescence using several substrates can unveil previously undocumented autoantibodies in multiple organs in lupus erythematosus, and that these findings could be utilized to complement existing diagnostic testing for this disorder.

    Full Text Available Os níveis de lipídeos séricos são características multifatoriais determinadas por um grande número de fatores genéticos e ambientais. A identificação do componente genético dessas características tem sido intensamente investigada nos últimos anos. Esses estudos têm enfocado principalmente polimorfismos nos genes que codificam proteínas estruturais e enzimas relacionadas com o metabolismo de lipídeos. Estudos mais recentes mostraram que o efeito desses polimorfismos depende em parte das interações dos diferentes genótipos com os fatores de risco clássicos tais como tabagismo, sobrepeso ou sedentarismo. A variabilidade encontrada nesses genes parece também influir na resposta a fármacos comumente utilizados no tratamento das hiperlipidemias.Serum lipid levels are multifactorial traits determined by a high number of genetic and environmental factors. The identification of the genetic component of this traits have been intensively investigated in the last years. These studies focused mainly on polymorphisms in genes coding for structural proteins and enzymes related to lipid metabolism. More recent studies showed that the effect of these polymorphisms depend in part on the interactions of different genotypes with classic risk factors like tabagism, overweight or physical inactivity. The variability observed in these genes seems to influence drug response of those commonly used in hyperlipidemia treatment.

    Recent literature suggests that Ca supplements have adverse effects on cardiovascular health. The effects of a Ca-rich supplement administered alone or in combination with short-chain fructo-oligosaccharides (scFOS) on serum lipids in postmenopausal women were examined using secondary data from a 24-month double-blind randomised controlled study. A total of 300 postmenopausal women were randomly assigned to daily supplements of 800 mg of Ca (2·4 g Aquamin) (Ca), 800 mg of Ca with 3 g of scFOS (CaFOS) or control (maltodextrin) (MD). A full lipid profile, body composition, blood pressure and a range of cytokines were measured at baseline and after 24 months. Intention-to-treat ANCOVA assessed treatment effects between the groups. A significant time-by-treatment effect was observed for LDL and total cholesterol for the Ca and CaFOS groups, with both groups having lower LDL and total cholesterol concentrations compared with MD after 24 months. The control group had mean (5·2 mmol/l) total cholesterol concentrations above the normal range (≤ 5 mmol/l) at 24 months, whereas values remained within the normal range in the treatment groups. There was no significant treatment effect on HDL-cholesterol, TAG, body composition, blood pressure or cytokine concentrations at 24 months, with the exception of IL-4, where there was a significant increase in the CaFOS group compared with the placebo. This study demonstrates a lipid-lowering effect of both the Ca-rich supplement alone and the supplement with scFOS. At the 4-year follow-up, there was no significant difference between the groups for reported diagnosed cardiovascular conditions. PMID:26669430

    The Incidence of childhood obesity and metabolic syndrome is increasing even in rural and semi-urban regions of India. Adipose tissue mass secretes several inflammatory proteins, which could potentially alter the metabolic processes, leading to several complications at the later stages of life. With limited studies on protein bound sialic acid (PBSA) as a marker of oxidative stress mediated inflammation in obese children, this study was aimed to assess and correlate PBSA with lipid peroxidation and other cardiometabolic risk factors like Insulin Resistance (IR), serum magnesium, and high sensitive C reactive Protein (hsCRP) levels in order to provide an insight into the degree of systemic inflammation and oxidative stress. This study included 62 obese children (≥95% percentile of the CDC chart) and 60 non obese controls. This study documents significant higher levels of PBSA, IR, Malondialdehyde (MDA), hsCRP and uric acid in obese children (p<0.001). PBSA was associated with IR, hsCRP, uric acid, hypomagnesaemia. Higher degrees of oxidative stress, Insulin resistance and low serum magnesium levels were noted in obese children. PBSA and hsCRP levels were elevated and were associated with Insulin resistance in obese children of South Indian population. PMID:25018680

    Full Text Available Nowadays, no-drug treatments (medicinal plants are novel therapeutic approaches in the treatment of diabetes. This study aimed at assessing the effect of Grape Seed extract on the blood glucose and lipid profile in diabetic rats. Thirty male adult rats were randomly selected and divided into three groups as nondiabetic control; diabetic control; diabetic rats treated with hydroalcoholic extract of grape seed. In diabetic groups, alloxan monohydrate (120 mg/kg was injected intraperitoneally to develop diabetes. Then the Test group received intraperitoneal injection of hydro-alcoholic extract of grape seed (100 mg/kg. At last, glucose, cholesterol, triglyceride, HDL, VLDL, LDL and insulin contents of the rats' serum sample were determined. Diabetic rats treated with extract showed a significant decrease in blood glucose level (p<0.05. Furthermore, compared diabetic group, in the extract-treated rats, there was a significant decrease in serum contents of total cholesterol (TC ,LDL,VLDL and TG, but a significant increase in insulin level and HDL (p<0.05. These results show that the hydroalcoholic extract of Grape Seed may be effective in the treatment of diabetes. This effect can be due to the presence of flavonoides and their antioxidant features.

    Extra virgin olive oil (EVOO) major and minor component anti-inflammatory effect on aorta was evaluated; Wistar rats were fed (9 weeks) on either a high-cholesterol diet (HCD) or a HCD supplemented with oils, i.e. EVOO, sunflower oil (SO), high-oleic sunflower oil (HOSO), or oil-products modified to their phenolic content, i.e. phenolics deprived-EVOO [EVOO(-)], SO enriched with the EVOO phenolics [SO(+)], HOSO enriched with the EVOO phenolics [HOSO(+)]. HCD induced dyslipidemia and resulted in higher aorta adhesion molecules levels at euthanasia. Groups receiving EVOO, EVOO(-), HOSO, HOSO(+) presented higher serum TC and LDL-c levels compared to cholesterol-fed rats; attenuation of aorta E-selectin levels was also observed. In EVOO/EVOO(-) groups, aorta vascular endothelial adhesion molecule-1 (VCAM-1) was lower compared to HCD animals. SO/SO(+) diets had no effect on endothelial dysfunction amelioration. Overall, our results suggest that major and/or minor EVOO constituents improve aorta E-selectin and VCAM-1, while serum lipids do not benefit.

    This study was conducted to determine the effects of dietary cerium oxide levels (0, 100, 200, 300 or 400 mg/kg) on the laying performance, egg quality, some blood serum parameters and egg lipid peroxidation of laying hen. In total, one hundred and twenty 22-week-old brown Lohman LSL laying hens were randomly assigned to five groups equally (n = 24). Each treatment was replicated six times. Dietary supplementation of cerium oxide had no significant effect on feed intake and egg weight. The addition of cerium oxide to the laying hens' feed improved feed conversion ratio and increased (p laying hens feed led to a significant (p hen diets. It was also observed that serum superoxide dismutase (SOD) activity and malondialdehyde (MDA) concentration decreased significantly with supplementation of cerium oxide in diets. Inclusion of cerium oxide resulted in a significant reduction in thiobarbituric acid reactive substance (TBARS) values in egg yolk in this study. It can be concluded that the addition of cerium oxide had positive effects on egg production, feed conversion ratio and egg shelf life. Based on the results of this study, it could be advised to supplement laying hens feed with cerium oxide as feed additives. PMID:26847677

    Full Text Available A high phosphorus (HP diet causes disorders of renal function, bone metabolism, and vascular function. We previously demonstrated that DNA microarray analysis is an appropriate method to comprehensively evaluate the effects of a HP diet on kidney dysfunction such as calcification, fibrillization, and inflammation. We reported that type IIb sodium-dependent phosphate transporter is significantly up-regulated in this context. In the present study, we performed DNA microarray analysis to investigate the effects of a HP diet on the liver, which plays a pivotal role in energy metabolism. DNA microarray analysis was performed with total RNA isolated from the livers of rats fed a control diet (containing 0.3% phosphorus or a HP diet (containing 1.2% phosphorus. Gene Ontology analysis of differentially expressed genes (DEGs revealed that the HP diet induced down-regulation of genes involved in hepatic amino acid catabolism and lipogenesis, while genes related to fatty acid β-oxidation process were up-regulated. Although genes related to fatty acid biosynthesis were down-regulated in HP diet-fed rats, genes important for the elongation and desaturation reactions of omega-3 and -6 fatty acids were up-regulated. Concentrations of hepatic arachidonic acid and eicosapentaenoic acid were increased in HP diet-fed rats. These essential fatty acids activate peroxisome proliferator-activated receptor alpha (PPARα, a transcription factor for fatty acid β-oxidation. Evaluation of the upstream regulators of DEGs using Ingenuity Pathway Analysis indicated that PPARα was activated in the livers of HP diet-fed rats. Furthermore, the serum concentration of fibroblast growth factor 21, a hormone secreted from the liver that promotes fatty acid utilization in adipose tissue as a PPARα target gene, was higher (p = 0.054 in HP diet-fed rats than in control diet-fed rats. These data suggest that a HP diet enhances energy expenditure through the utilization of free fatty

    Alcoholism and obesity are strongly associated with several disorders including heart and liver diseases. This study evaluated the effects of rutin treatment in serum, heart and liver tissues of rats subjected to a combination of hypercaloric diet (HD) and chronic ethanol consumption. Rats were divided into three groups: Control: rats fed a standard diet and drinking water ad libitum; G1: rats fed the HD and receiving a solution of 10% (v/v) ethanol; and G2: rats fed the HD and ethanol solution, followed by injections of 50 mg/kg(-1) rutin as treatment. After 53 days of HD and ethanol exposure, the rutin was administered every three days for nine days. At the end of the experimental period (95 days), biochemical analyses were carried out on sera, cardiac and hepatic tissues. Body weight gain and food consumption were reduced in both the G1 and G2 groups compared to control animals. Rutin effectively reduced the total lipids (TL), triglycerides (TG), total cholesterol (TC), VLDL, LDL-cholesterol and glucose levels, while it increased the HDL-cholesterol in the serum of G2 rats, compared to G1. Although rutin had no effect on total protein, albumin, uric acid and cretinine levels, it was able to restore serum activities of alkaline phosphatase (ALP), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine kinase (CK) in animals fed HD and receiving ethanol. Glycogen stores were replenished in both hepatic and cardiac tissues after rutin treatment. Moreover, rutin consistently reduced hepatic levels of TG and TC and cardiac AST, ALT and CK activities. Thus, rutin treatment was effective in reducing the risk factors for cardiac and hepatic disease caused by both HD and chronic ethanol consumption. PMID:25204084

  4. Apolipoprotein M affecting lipid metabolism or just catching a ride with lipoproteins in the circulation?

    DEFF Research Database (Denmark)

    Dahlbäck, B; Nielsen, Lars Bo

    2009-01-01

    Apolipoprotein M (apoM) is a novel apolipoprotein found mainly in high-density lipoproteins (HDL). Its function is yet to be defined. ApoM (25 kDa) has a typical lipocalin ss-barrel fold and a hydrophobic pocket. Retinoids bind apoM but with low affinity and may not be the natural ligands. Apo......M retains its signal peptide, which serves as a hydrophobic anchor to the lipoproteins. This prevents apoM from being lost in the urine. Approximately 5% of HDL carries an apoM molecule. ApoM in plasma (1 microM) correlates strongly with both low-density lipoprotein (LDL) and HDL cholesterol, suggesting...... a link to cholesterol metabolism. However, in casecontrol studies, apoM levels in patients with coronary heart disease (CHD) and controls were similar, suggesting apoM levels not to affect the risk for CHD in humans. Experiments in transgenic mice suggested apoM to have antiatherogenic properties...

    Full Text Available To investigate the effects of daily supplementation with docosahexaenoic acid (DHA on coronary heart disease risks in 38 middle-aged men with hypertension and/or hypercholesterolemia in Scotland, a five-week double-blind placebo-controlled dietary supplementation with either 2 g of DHA or active placebo (1 g of olive oil was conducted. Percent composition of DHA in plasma phospholipids increased significantly in DHA group. Systolic and diastolic blood pressure and heart rate decreased significantly in DHA group, but not in placebo group. High-density lipoprotein cholesterol (HDL-C increased significantly, and total cholesterol (TC/HDL-C and non-HDL-C/HDL-C ratios decreased significantly in both groups. There was no change in TC and non-HDL-C. We conclude that 2 g/day of DHA supplementation reduced coronary heart disease risk factor level improving blood pressure, heart rate, and lipid profiles in hypertensive, hypercholesterolemic Scottish men who do not eat fish on a regular basis.

    Cecropia obtusifolia and Marrubium vulgare have been widely used in Mexican traditional medicine for the control of type 2 diabetes. In order to evaluate the clinical effect produced by the aqueous extract from these species on type 2 non-controlled diabetes mellitus, a total of 43 outpatients were included. Based on the European NIDDM (policy group) criteria, only patients with poor response to the conventional treatment were selected. All patients maintained their medical treatment and also received a prepared infusion of the dry leaves of the plant treatment for 21 days. In a double-blind manner, the patients were randomly grouped as follows: 22 patients were treated with C. obtusifolia and 21 with M. vulgare. The fasting blood glucose values were reduced by 15.25% on patients treated with C. obtusifolia, while cholesterol and triglycerides were decreased by 14.62% and 42.0%, respectively (ANOVA pvulgare, the plasma glucose level was reduced by 0.64% and cholesterol and triglycerides by 4.16% and 5.78%, respectively. When the results were compared between groups, significant differences in glucose and cholesterol diminution were found. The obtained results showed that the infusion prepared with the leaves of C. obtusifolia (containing 2.99+/-0.14mg of chlorogenic acid/g of dried plant) produced beneficial effects on carbohydrate and lipid metabolisms when it was administered as an adjunct on patients with type 2 diabetes with poor response to conventional medical treatment.

    Full Text Available This study was performed to see how pioglitazone at low doses could affect blood biomarkers related to atherosclerosis and aging. The effects of an add-on treatment with pioglitazone (15 mg for males and 7.5 mg for females for 6 months were assessed in 24 outpatients (12 males, 12 females with type 2 diabetes aged ≥ 70 years. As doses of sulfonylurea were reduced in 10 patients, no significant differences in HbA1c and glucose levels were seen. After the treatment, serum levels of HDL cholesterol, arachidonic acid (predominant in males, and high-molecular-weight adiponectin significantly increased. The level of dehydroepiandrosterone sulfate significantly decreased. No significant changes were seen in those of small dense LDL cholesterol, high-sensitivity C-reactive protein, and amyloid beta peptides 1–40 and 1–42. There was a slight but significant increase in body weight, but apparent adverse effects were not observed. In conclusion, pioglitazone at low doses increased serum adiponectin, HDL cholesterol, and arachidonic acid levels but decreased serum dehydroepiandrosterone level, not associated with glycemia, in elderly Japanese people with type 2 diabetes. An optimal dose of pioglitazone should be sought for to minimize its adverse effects and to fully exert its pleiotropic effects such as antiatherosclerotic and antiaging effects.

    Left ventricular hypertrophy (LVH) is considered an independent risk factor even in the absence of systemic hypertension. Electrocardiographic (ECG) LVH with repolarisation changes has been found in some countries to carry more coronary risk than LVH alone. How far this observation is true among adult Nigerians is not known. We therefore decided to study adult Nigerians with ECG-LVH with or without ST-T waves changes and compare them with normal age matched controls (without ECG-LVH) in relation with established modifiable risk factors such as systemic hypertension (BP), body mass index (BMI), fasting blood sugar (FBS) and serum lipids such as total cholesterol (Tc), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Adult Nigerians who were consecutively referred to the ECG laboratory were randomly recruited. Three hundred patients were studied. Their blood pressures (BP) as well as body mass indices were recorded after recording their resting 12 read ECG using portable Seward 9953 ECG machine. Their waist-hip ratio (WHR) was also recorded. Blood samples were taken to determine their fasting blood sugar and serum lipids. Their ECG tracings were read by the cardiologists involved in the study while the blood samples were analysed by the chemical pathologist also involved in the study. At the end of the ECG reading, the patients were divided into 3 groups according to whether there was no ECG-LVH (control group A), ECG-LVH alone (group B), and ECG-LVH with ST-T waves changes (group C). One hundred and fifty (50%) patients belonged to group A, 100 (33.3%) patients to group B and 50 (16.7%) group C. Group B patients were found to have higher modifiable risk factors in form of systemic BP. Tc, LDL-C, and WHR compared to group A. However, the group C patients had increased load of these coronary risk factors in terms of BP elevation, higher BMI, FBS, and scrum cholesterol compared to group B. In addition

  11. Relationships between abdominal fat distribution assessed by computer tomography, body composition, serum lipids, plasma glucose and cardiorespiratory functions in obese children

    International Nuclear Information System (INIS)

    Visceral abdominal fat to subcutaneous abdominal fat ratio (V/S ratio) is a predictor for cardiac disease, metabolic disease, and hypertension in obese adults. This study determined the histopathological value of V/S ratio in obese children using computed tomography (CT). The subjects were 37 boys and 26 girls with overweight by more than 20%, whose ages ranged from 3 to 16 years. Although the percentage of standard body weight (SBW), percentage of body fat (BF), and body mass index (BMI) were correlated with each other, there was no correlation between the V/S ratio and the three predictors. Thus, the V/S ratio is completely different from the other obesity predictors in children. The V/S ratio in children of 20% or more overweight of SBW was 0.28±0.11. The V/S ratio of 0.4, used as an obesity predictor in adults, was not considered suitable in the case of children. Liver function, serum lipid levels, and serum glucose correlated with the percentage of SBW, BMI, and the percentage of BF, but not correlated with the V/S ratio. According to the V/S ratio, the patients were divided into the group of V/S ratio of less than 0.28 (group I, n=34) and the group of V/S ratio of 0.28 or more (group II, n=27). There was no significant difference in age, percentage of SBW, BMI, and percentage of BF. Triglyceride was significantly higher in group II than group I, but there was no significant difference in plasma glucose and other lipids, body composition, blood pressure or respiratory function. Of note, the V/S ratio of 0.4 or more was seen in only 9 of the 61 children (14.7%). These findings suggest that the V/S ratio for children is a predictor different from that in the case of adults.

    Full Text Available The ability of eight yeast strains to utilize glycerol as a sole carbon source and accumulate lipids in a chemically defined medium was screened. Among the yeasts, Yarrowia lipolytica strains DSM 70561 and JDC 335 grew to high cell densities on glycerol. These strains were further tested for lipid accumulation under varying nutritional conditions in Erlenmeyer flasks. The results showed that strains DSM 70561 and JDC 335 accumulated lipids up to 37.1 % and 54.4 % of total cell dry weight, respectively, when the defined medium was supplemented with 1 g/L urea and 2 g/L yeast extract. The lipids accumulated by the two yeasts contained a high proportion of C16:0, C18:1, C18:2 and C18:0 fatty acids. The results suggest that Y. lipolytica strains DSM 70561 and JDC 335 have the potential for converting crude glycerol into fatty acids which can in turn be utilized as substrate for biodiesel production.

    Prunus divaricata (Alloocheh) is a small tree cultivating in Iran, Middle East and central Asia. Prunus genus has many species with anti-oxidant, anti-hyperlipidemia and anti-hyperglycemia effects. In the present study the anti-diabetic and anti-hyperlipidemic effects of P. divaricata fruits were examined in normal and streptozotocin (STZ)-induced diabetic rats. Both groups, control and reference rats received normal saline and glibenclamide respectively. Test groups were treated with Prunus freeze dried juice (PFDJ, 200, 400, 800 mg/kg) and Prunus freeze dried extract (PFDE, 100, 200, 400 mg/kg) started at the 3(rd) day of the experiment and continued for 27 days thereafter. Weight changes of animals were checked periodically. Fasting blood glucose (FBG) level as well as serum triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol were determined. Different treatments had no significant effect on body weight increments of normal rats, while in diabetic rats, PFDJ (800 mg/kg) and PFDE (400 mg/kg) opposed with weight loss. In acute phase of experiment (0-8 h of 3(rd) day), none of tested fractions were effective in reducing FBG and serum lipids of normal rats. During the sub-acute phase (13(th) and 30(th) days) however, the greatest test doses of PFDJ (800 mg/kg) and PFDE (400 mg/kg) induced hypoglycema. In diabetic groups, PFDJ and PFDE, at all test doses, could diminish FBG during sub-acute phase of the experiment. In addition, PFDJ and PFDE at most examined doses could diminish TG significantly and they were also effective on cholesterol derivatives in different magnitude. PMID:26339257

    We explored the changes in viability and lipid profile occurring in cancer cells, murine melanoma cells (B16F10 cells) and human cervical carcinoma cells (HeLa cells), when exposed to 24 h-treatments with an n-3 PUFA-rich oil obtained by supercritical extraction with CO2 from Mugil cephalus processed roe (bottarga). The composition of the major lipid classes of bottarga oil was determined by the (13)C NMR technique. Reversed-phase HPLC with DAD/ELSD detection was performed to analyze cells' total fatty acid profile and the levels of phospholipids, total/free cholesterol, triacylglycerols, and cholesteryl esters. Cell-based fluorescent measurements of intracellular membranes and lipid droplets were performed on bottarga oil-treated cells using the Nile red staining technique. The treatments of cancer cells with bottarga oil reduced the viability and affected the fatty acid profile, with a significant n-3 PUFA increase in treated cells. Mullet roe oil uptake modulated the cancer cell lipid composition, inducing a remarkable incorporation of health beneficial n-3 PUFA in the polar and neutral lipid fractions. Bottarga oil treatment influenced the synthesis of intracellular membranes and accumulation of cytoplasmic lipid droplets in cancer cells. PMID:27603212

    Graphical abstract: -- Highlights: •Lipidomics, high resolution mass spectrometry, polarity switching, serum, canine mammary cancer. -- Abstract: Lipids represent an extended class of substances characterized by such high variety and complexity that makes their unified analyses by liquid chromatography coupled to either high resolution or tandem mass spectrometry (LC–HRMS or LC–MS/MS) a real challenge. In the present study, a new versatile methodology associating ultra high performance liquid chromatography coupled to high resolution tandem mass spectrometry (UHPLC–HRMS/MS) have been developed for a comprehensive analysis of lipids. The use of polarity switching and “all ion fragmentation” (AIF) have been two action levels particularly exploited to finally permit the detection and identification of a multi-class and multi-analyte extended range of lipids in a single run. For identification purposes, both higher energy collision dissociation (HCD) and in-source CID (collision induced dissociation) fragmentation were evaluated in order to obtain information about the precursor and product ions in the same spectra. This approach provides both class-specific and lipid-specific fragments, enhancing lipid identification. Finally, the developed method was applied for differential phenotyping of serum samples collected from pet dogs developing spontaneous malignant mammary tumors and health controls. A biological signature associated with the presence of cancer was then successfully revealed from this lipidome analysis, which required to be further investigated and confirmed at larger scale.

    Introduction & Objective: Diabetes mellitus is one of the most common endocrine disorders in the world which affects glucose metabolism in the body. Diabetes mellitus is due to lack of insulin secretion and/or failure in insulin action. Researches conducted in the last few decades on plants have reported anti-diabetic properties for some herbs and their traditional use for diabetes treatment. Capparis spinosa is one of these herbs which are used as an anti-diabetic treatment in tribal medici...

    Tuber and root crops virtually exclusively accumulate storage products in the form of carbohydrates. An exception is yellow nutsedge (Cyperus esculentus) in which tubers have the capacity to store starch and triacylglycerols (TAG) in roughly equal amounts. This suggests that a tuber crop can efficiently handle accumulation of energy dense oil. From a nutritional as well as economic aspect, it would be of interest to utilize the high yield capacity of tuber or root crops for oil accumulation similar to yellow nutsedge. The transcription factor WRINKLED1 from Arabidopsis thaliana, which in seed embryos induce fatty acid synthesis, has been shown to be a major factor for oil accumulation. WRINKLED1 was expressed in potato (Solanum tuberosum) tubers to explore whether this factor could impact tuber metabolism. This study shows that a WRINKLED1 transcription factor could induce triacylglycerol accumulation in tubers of transformed potato plants grown in field (up to 12 nmol TAG/mg dry weight, 1% of dry weight) together with a large increase in polar membrane lipids. The changes in metabolism further affected starch accumulation and composition concomitant with massive increases in sugar content. PMID:26914183

    Lipid oxidation is a serious problem for oil-containing food products because it negatively affects shelf life and nutritional composition. An antioxidant strategy commonly employed to prevent or delay oxidation in foods is to remove oxygen from the closed food-packaging system. An alternative technique is use of an edible oxygen scavenger to remove oxygen within the food. Ascorbic acid (AA) is a particularly promising antioxidant because of its natural label and multiple antioxidative functions. In this study, AA was tested as an oxygen scavenger in buffer and an oil-in-water (O/W) emulsion. The effects of transition metals on the ability of AA to scavenge oxygen were determined. Headspace oxygen decrease less than 1% in the medium-chain triacylglycerol (MCT) O/W emulsion system (pH 3 and 7). AA was able to almost completely remove dissolved oxygen (DO) in a buffered solution. Transition metals (Fe(2+) and Cu(+)) significantly accelerated the degradation of AA; however, iron and copper only increased DO depletion rates, by 10.6-16.4% from day 1 to 7, compared to the control. AA (2.5-20 mM) decreased DO in a 1% O/W emulsion system 32.0-64.0% and delayed the formation of headspace hexanal in the emulsion from 7 to over 20 days. This research shows that, when AA is used in an O/W emulsion system, oxidation of the emulsion system can be delay by multiple mechanisms. PMID:25650525

    The effects of in vitro and in vivo modifications of nuclear envelope lipid on DNa leakage and on ATP-stimulated RNA release from isolated rat liver nuclei were investigated. The modifications included corn-oil feeding of the animals to alter the fatty acid composition of the lipids, phospholipase treatment of the isolated nuclei, and extraction of the total lipid with Triton X-100. Significant changes in lipid composition and approximate order parameter values of the spin-label 5-doxylstearate resulted, but there was no significant effect on RNA transport rate. It was concluded that the nuclear envelope lipid does not play any important part in nucleocytoplasmic RNA transport in mammalian liver.

    Objective:To explore the serum lipid profile of patients with Parkinson’s disease (PD) and the role of the lipids in the occurrence of stroke in PD patients. Methods: A retrospective study was performed on PD patients (PD group, n=161), healthy controls (HC group, n=161) and acute cerebral infarction patients (CI group, n=161). The levels of serum lipid profile, total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), were compared in the three groups and binary logistic regression was used to analyze the differences of variables in PD and CI groups. Results: The TG and LDL-C levels were significantly lower in the PD group than those in the HC group and CI group (P<0.05). The LDL-C level was higher in the PD group than that in the CI group (P<0.05). The occurrence of patients with hypertension and dia-betes in the PD group was lower than those in the CI group (P<0.05). Binary Logistic regressions showed that HDL-C, LDL-C, history of hypertension and diabetes were risk factors of the occurrence of stroke in PD patients. Conclusion: PD patients show lower levels of TG and LDL-C and higher HDL-C level than those in acute cerebral infarction patients. High level of HDL-C and low level of LDL-C may be risk factors of stroke in PD patients.%目的:研究帕金森病(PD)患者血脂表达情况,探讨血脂水平对 PD 患者发生脑卒中的影响。方法:回顾性纳入 PD 患者、急性脑梗死患者及同期健康体检者各161例,分别为 PD 组、脑梗组及对照组。比较3组的血脂包括总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)水平及其他因素;以 PD 组、脑梗组为因变量对2组有统计学差异的变量进一步采用二分类 Logistic 回归方法分析。结果:PD 组 TG、LDL-C 水平显著低于对照组及脑梗组(均 P<0.05),HDL-C

    Dissolved organic compounds in oil sands process affected water (OSPW) are known to be responsible for most of its toxicity to aquatic organisms, but the complexity of this mixture prevents use of traditional bottom-up approaches for predicting toxicities of mixtures. Therefore, a top-down approach to predict toxicity of the dissolved organic fraction of OSPW was developed and tested. Accurate masses (i.e., m/z) determined by ultrahigh resolution mass spectrometry in negative and positive ionization modes were used to assign empirical chemical formulas to each chemical species in the mixture. For each chemical species, a predictive measure of lipid accumulation was estimated by stir-bar sorptive extraction (SBSE) to poly(dimethyl)siloxane, or by partitioning to solid-supported lipid membranes (SSLM). A narcosis mode of action was assumed and the target-lipid model was used to estimate potencies of mixtures by assuming strict additivity. A model developed using a combination of the SBSE and SSLM lipid partitioning estimates, whereby the accumulation of chemicals to neutral and polar lipids was explicitly considered, was best for predicting empirical values of LC50 in 96-h acute toxicity tests with embryos of fathead minnow (Pimephales promelas). Model predictions were within 4-fold of observed toxicity for 75% of OSPW samples, and within 8.5-fold for all samples tested, which is comparable to the range of interlaboratory variability for in vivo toxicity testing.

    Extracts from various morphological parts of Annona muricata Linn. (Annonaceae) are widely used medicinally in many parts of the world for the management, control and/or treatment of a plethora of human ailments, including diabetes mellitus (DM). The present study was undertaken to investigate the possible protective effects of A. muricata leaf aqueous extract (AME) in rat experimental paradigms of DM. The animals used were broadly divided into four (A, B, C and D) experimental groups. Group A rats served as 'control' animals and received distilled water in quantities equivalent to the administered volumes of AME and reference drugs' solutions intraperitoneally. Diabetes mellitus was induced in Groups B and C rats by intraperitoneal injections of streptozotocin (STZ, 70 mg kg(-1)). Group C rats were additionally treated with AME (100 mg kg(-1) day(-1), p.o.) as from day 3 post STZ injection, for four consecutive weeks. Group D rats received AME (100 mg kg(-1) day(-1) p.o.) only for four weeks. Post-euthanization, hepatic tissues were excised and processed biochemically for antioxidant enzymes and lipid profiles, such as catalase (CAT), reactive oxygen species (ROS), glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), thiobarbituric acid reactive substances (TBARS), triglycerides (TG), total cholesterol (TC), high density lipoprotein (HDL) and low density lipoprotein (LDL), respectively. Treatment of Groups B and C rats with STZ (70 mg kg(-1) i. p.) resulted in hyperglycaemia, hypoinsulinaemia, and increased TBARS, ROS, TC, TG and LDL levels. STZ treatment also significantly decreased (p<0.05) CAT, GSH, SOD, GSH-Px activities, and HDL levels. AME-treated Groups C and D rats showed significant decrease (p<0.05) in elevated blood glucose, ROS, TBARS, TC, TG and LDL. Furthermore, AME treatment significantly increased (p<0.05) antioxidant enzymes' activities, as well as serum insulin levels. The findings of this laboratory animal study

    为了确定断奶应激对仔猪脂类营养代谢的影响,随机选取体重相近的12头断奶仔猪,分别于仔猪断奶时,断奶后第7天、第14天采取血液进行血清脂类代谢指标测定。结果显示,被检仔猪血清CHO、TG活性在断奶后显著(P〈0.05)或极显著升高(P〈0.01)。血清HDL、LDL在整个试验期间虽有变化,但均无统计学意义(P〉0.05)。表明断奶后第14天时,仔猪对脂类物质吸收增强,脂肪沉积增多,该时期可在饲料中适当添加脂类营养物质,这将有利于调节机体代谢和营养调控。%In order to understand the effect of weanling stress on serum lipid metabolism of piglets, 12 weaned piglets with similar body weight were randomly selected, and serum lipid metabolism indexes of their blood were determined when piglets were weaned, 7 days and 14 days after weaning. Result showed that CHO and TG activities of piglet serum were significantly or very significantly increased, but HDL and LDL activities of serum had no significant change. It is suggested that after piglets were weaned for 14 days, they strengthened to absorb lipid materials, and fat deposition increased, so serum nutrients should be properly added into feed during this stage, and it is helpful to adjust body′s metabolism and nutrition regulation.

  13. Methylmalonic and propionic acidemias: lipid profiles of normal and affected human skin fibroblasts incubated with [1-14C]propionate

    International Nuclear Information System (INIS)

    Normal human skin fibroblasts and those from methylmalonic acidemia and propionic acidemia patients were grown in culture. Following incubation with [1-14C]propionate, the major lipid classes in the cells were separated by thin layer chromatography and isolated fractions analyzed by radio gas chromatography for the presence of odd-numbered long-chain fatty acids; the pattern of even-numbered long-chain fatty acids was obtained also. Normal fibroblasts incorporated a small percentage of propionate into odd-numbered fatty acids which were present in all lipids studied. The abnormal cells incorporated a larger amount while maintaining the characteristic ratios of odd-numbered fatty acids found in the normal line. Most of the radioactivity was associated with phospholipids which are the predominant constituents of cell membranes. A characteristic C15/C17 ratio was found for different phospholipids and the triglyceride fraction; pentadecanoic acid was the principal odd-numbered fatty acid utilized in the assembly of complex lipids. Compared to even-numbered long-chain fatty acids the absolute amount of odd-numbered fatty acids was low (1-2%), even in affected cells. An unusual polar lipid fraction was isolated in the course of the study. In the normal cell it contained several unlabeled eicosanoids which were missing from the same fraction of both affected cell lines

    Adrien Weingärtner

    Full Text Available Maintenance and regulation of the asymmetric lipid distribution across eukaryotic plasma membranes is governed by the concerted action of specific membrane proteins controlling lipid movement across the bilayer. Here, we show that the miltefosine transporter (LdMT, a member of the P4-ATPase subfamily in Leishmania donovani, and the Cdc50-like protein LdRos3 form a stable complex that plays an essential role in maintaining phospholipid asymmetry in the parasite plasma membrane. Loss of either LdMT or LdRos3 abolishes ATP-dependent transport of NBD-labelled phosphatidylethanolamine (PE and phosphatidylcholine from the outer to the inner plasma membrane leaflet and results in an increased cell surface exposure of endogenous PE. We also find that promastigotes of L. donovani lack any detectable amount of phosphatidylserine (PS but retain their infectivity in THP-1-derived macrophages. Likewise, infectivity was unchanged for parasites without LdMT-LdRos3 complexes. We conclude that exposure of PS and PE to the exoplasmic leaflet is not crucial for the infectivity of L. donovani promastigotes.

    ObjectiveTo explore the characteristic of serum lipids metabolism under different degrees of hypothyroidism and course, the study observed the dynamic changes in serum lipids metabolism after hormone replacement therapy in patients with hypothyroidism. Methods97 cases of patients with hypothyroidism were collected, 32 patients with subclinical hypothyroidism, 28 patients with moderate hypothyroidism, 37 cases with severe hypothyroidism, and 31 cases of healthy. All patients were examined before and one month after hormone replacement therapy, testing serum free triiodothyronine three (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), total cholesterol(TC), triglyceride(TG), high density lipoprotein(HDL-C), low density lipoprotein (LDL-C), apolipoprotein A(ApoA), apolipoprotein B(ApoB) and lipoprotein (a)Lp(a). Results Serum lipids of the severe hypothyroidism group were higher than the control group. TC, LDL-C, ApoA, ApoB and Lp(a) of the moderate hypothyroidism group were higher than the control group. ApoA and Lp(a) of the moderate hypothyroidism group were higher than the control group. The serum lipids were negatively related to FT3 and FT4, and TSH was positively correlated. Different degrees of hypothyroidism had different effects on serum lipids. The more increase course of hypothyroidism, the more obvious increase in the serum lipids level. Hormone replacement therapy in patients with hypothyroidism, the serum lipids returned to be normal after one month except for Lp(a).ConclusionHypothyroidism can increase serum lipids. The more increase degree and course of hypothyroidism, the more obvious increase in serum lipids level. With the hormone replacement therapy, the serum lipids resumed with hypothyroidism condition improved gradually, serum lipids returned to be normal before the thyroid function.%目的:探讨不同程度甲状腺功能减退症和病程对血脂的影响,并观察甲状腺功能减退症患者激素替代治疗后血脂

    significantly increased also one day after UfCP exposure. Immunohistochemistry localized highest concentrations of PGE2 especially in AM one day after UfCP exposure. Conclusion Our results suggest that UfCP exposure affects the balance between pro- and anti-inflammatory lipid mediators. In allergic mice, where the endogenous balance of pro- and anti-inflammatory mediators is already altered, UfCP exposure aggravates the inflammation and the increase in anti-inflammatory, pro-resolving lipid mediators is insufficient to counterbalance the extensive inflammatory response. This may be a contributing mechanism that explains the increased susceptibility of asthmatic patients towards particle exposure.

    Full Text Available Introduction: Pathogenic role of free radicals are well known in various metabolic diseases. They originate from internal and external sources of body. Essential roles of antioxidant defense system for cellular redox regulation and free radical scavenging activity were described in this study. Many in vitro investigations have shown that turmeric (TE and carrot seed extract (CSE exhibits to possess antioxidant activities. In this study, we evaluated the antioxidant potentials of ethanolic TE and CSE based on in vivo experiment in the rats. Methods: Animals were assigned to six groups: the 1st and 2nd groups were control groups and 2nd group received 0.2 ml dimethyl sulphoxide as vehicle treated group; other four experimental groups received different doses of TE (100, 200 mg/kg b.w. and CSE (200, 400 mg/kg b.w. by gavages, respectively for a period of one month. The indicators of oxidative stress, lipids peroxidation, markers of hepatocyte injury and biliary function markers were measured. Results: The levels of superoxide dismutase, catalase, and glutathione peroxidase were significantly stimulated in the hepatic tissue of treatment groups. The malondialdehyde contents of liver tissue were significantly reduced in the groups fed with TE and CSE. Serum levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase, in treated groups were found to be significantly decreased, whereas albumin and total protein increased as compared to the control groups (P<0.05. Conclusion: this study showed that the regular intake of TE and CSE through the diet can improve antioxidant status and inhibit peroxidation activity in the liver tissue so that using these extracts may protect tissue oxidative stress.

    BACKGROUND/OBJECTIVES: The aim was to examine the association of genetic risk scores (GRSs) of vitamin B12 and folate-associated variants with blood pressure and lipids. SUBJECTS/METHODS: The study included 12 532 adults from three population-based studies (Inter99, Health2006 and Dan-MONICA10......) conducted in Denmark. GRSs were calculated by summarising the number of vitamin B12 and folate increasing alleles. Weighted GRSs were calculated as the sum of weights for each allele corresponding to genetic effects sizes. RESULTS: GRSs for serum vitamin B12 and folate were associated with serum vitamin B12...... and folate, respectively. The β coefficients (95% confidence interval (CI), P-value) for regression of log-transformed serum B12/folate on the weighted GRSs were 0.57 (0.54, 0.61), P

    Objective To investigate the serum lipids levels of Chinese men with chronic paraplegia.Methods A total of 650 male paraplegics admitted to the China Rehabilitation Research Center (CRRC) for rehabilitation therapy from Jan 2004-Dec 2008 were investigated. The inclusion criteria were a definite paraplegic history (T2-L5 spinal cord injury); complete data; age 18-60 years; and no history of stroke. TG, TC, LDL and HDL serum lipid profiles were studied. Results These male paraplegics showed significantly higher mean TG and TC levels and lower mean HDL levels than the nation-wide averages for similar males ( TG 1.72 mmol/L vs. 1.36 mmol/L; TC4.42 mmol/L vs. 4.30 mmoL/L; HDL 0.99 mmol/L vs. 1.18 mmol/L). No difference in average LDL levels was found. TG, TC and LDL levels were correlated positively with age, but HDL was not. Duration of paraplegia correlated positively with HDL levels, but negatively with LDL. The prevalence of dyslipidemia was 67% , and the prevalence of low HDL was 64%. Conclusions The serum lipid profiles of the young male paraplegics showed a high prevalence of dislipidemia, significantly low HDL levels with a high prevalence of low HDL, and no correlation with age. TG, TC and LDL levels increased with age. The duration of paraplegia was correlated positively with HDL but negatively with LDL, probably due to increased exercise of the upper limbs.%目的 通过流行病学调查来了解青壮年男性截瘫患者血脂代谢水平特点,探讨双下肢运动功能缺失对男性血脂的影响.方法 对中国康复研究中心2004年至2008年因截瘫入院进行康复治疗的男性患者进行入院状态调查.人选要求:①病史明确(T2~L5平面脊髓损伤致双下肢瘫痪);②资料完整;③18周岁≤年龄≤60岁;④非脑卒中患者.共650例患者入选,对血脂指标[甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)]进行分析.结果 青壮年男性截瘫患者TG、TC水平显著高

    A digestibility trial was performed with gilthead sea bream juveniles (IBW = 72 g) fed four diets differing in lipid source (fish oil, FO; or a blend of vegetable oil, VO) and starch content (0 %, CH-; or 20 %, CH+) to evaluate the potential interactive effects between carbohydrates and VO on the processes involved in digestion, absorption and transport of lipids and glucose. In fish fed VO diets a decrease in lipid digestibility and in cholesterol (C), High Density Lipoprotein(HDL)-C and Low Density Lipoprotein (LDL)-C (only in CH+ group) were recorded. Contrarily, dietary starch induced postprandial hyperglycemia and time related alterations on serum triacylglycerol (TAG), phospholipid (PL) and C concentrations. Fish fed a CH+ diet presented lower serum TAG than CH- group at 6 h post-feeding, and the reverse was observed at 12 h post-feeding for TAG and PL. Lower serum C and PL at 6 h post-feeding were recorded only in VOCH+ group. No differences between groups were observed in hepatic and intestinal transcript levels of proteins involved in lipid transport and hydrolysis (FABP, DGAT, GPAT, MTP, LPL, LCAT). Lower transcript levels of proteins related to lipid transport (ApoB, ApoA1, FABP2) were observed in the intestine of fish fed the CH+ diet, but remained unchanged in the liver. Overall, transcriptional mechanisms involved in lipid transport and absorption were not linked to changes in lipid serum and digestibility. Dietary starch affected lipid absorption and transport, probably due to a delay in lipid absorption. This study suggests that a combination of dietary VO and starch may negatively affect cholesterol absorption and transport. PMID:27023202

    Full Text Available The value of CD30 and the soluble circulating fragment of CD30 (sCD30 for atopic dermatitis (AD remains unclear. In particular, little is known about the effects of age, duration of disease and Scoring Atopic Dermatitis index (SCORAD on the levels of serum sCD30 in patients affected by AD. In the present study, we have analysed serum sCD30 levels of adult patients affected by AD. The study's population includes 18 non-smoking outpatients, with a diagnosis of AD. As a control group we studied 18 non-atopic subjects from laboratory staff, matched for sex and age. These subjects had no history of AD, urticaria or seasonal or perennial rhinitis or asthma, and had negative skin prick test to a panel of allergens.

    Full Text Available Abstract Background Epidemiological studies associate consumption of whole grain foods, including breads, with reduced cardiovascular disease (CVD risk; however, few studies have compared wheat whole grains with wheat refined grains. Methods This study investigated effects of 6-week consumption of whole grain wheat sourdough bread in comparison to white bread on fasting serum lipids in normoglycemic/normoinsulinemic (NGI; n = 14 and hyperglycemic/hyperinsulinemic (HGI; n = 14 adults. The influence of single-nucleotide polymorphisms, 3 within the APOE gene (E2, E3, E4 and 2 within the hepatic lipase gene promoter (LIPC -514C>T, LIPC -250G>A were considered. Results At baseline, HGI participants had significantly higher body weight, waist circumference, body fat, and fasted glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR, glucagon, triacylglycerols (TAG and TAG:HDL-cholesterol, compared to NGI participants; however, none of these in addition to none of the other serum lipids, differed between bread treatments, within either participant group. For participants with the APOE E3/E3 genotype, LDL-cholesterol (P = 0.02 increased in the NGI group (n = 7, and TAG (P = 0.03 and TAG:HDL-cholesterol (P = 0.04 increased in the HGI group (n = 10, following consumption of whole grain wheat sourdough compared to white bread. Conclusions In summary, 6-week consumption of whole grain wheat sourdough bread did not significantly modulate serum lipids in NGI or HGI adults; however, it significantly increased LDL-cholesterol, TAG and TAG:HDL-cholesterol in participants with the APOE E3/E3 genotype. These data add to limited literature comparing wheat whole grains to wheat refined grains on CVD risk and highlight the need to consider genetic variation in relation to lipoprotein lipid content and CVD risk.

    Knowledge is limited on the efficacy of hindgut-fermentable dietary fibre to reduce blood, bile and body tissue cholesterol levels. In three experiments with growing pigs the effects of different kinds and levels of bacterially fermentable fibre (BFS) on cholesterol metabolism were examined. Various diets calculated to have similar contents of metabolizable energy were supplied for complete fattening periods. In the first experiment, a stepwise increase from 12 to 20% BFS was performed by supplementing diets with fermentable fibre from sugar beet pulp (modelling hemicelluloses and pectin). Beet pulp, rye bran (modelling cellulose) and citrus pulp (pectin) were offered either independently or in a mixture in the second experiment. These diets were opposed to rations characterized in carbohydrate type by starch either mostly non-resistant (cassava) or partly resistant (maize) to small intestinal digestion. The third experiment was planned to explore the interactions of BFS from citrus pulp with fat either through additional coconut oil/palm kernel oil blend or full-fat soybeans. In all experiments the increase of the BFS content was associated with a constant (cellulose) or decreasing (hemicelluloses, pectin) dietary proportion of non-digestible fibre. In experiment 1 an inverse dose-response relationship between BFS content and cholesterol in blood serum and adipose tissue as well as bile acid concentration in bile was noted while muscle cholesterol did not respond. In experiment 2 the ingredients characterized by cellulose and hemicelluloses/pectin reduced cholesterol-related traits relative to the low-BFS-high-starch controls whereas, except in adipose tissue cholesterol content, the pectinous ingredient had the opposite effect. However, the changes in serum cholesterol mainly affected HDL and not LDL cholesterol. Adipose tissue cholesterol also was slightly lower with partly resistant starch compared to non-resistant starch in the diet. Experiment 3 showed that

    Objective To investigate the association between multiple system atrophy (MSA) and serum lipids.Methods One hundred and thirteen patients with MSA admitted to Chinese PLA General Hospital from April 2012 to April 2014, and another 132 age- and gender-matched healthy subjects were enrolled in this study. Patients' lipid contents, including total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A-1 (ApoA1), apolipoproteins B (ApoB), were observed. The risk factors of MSA patients were analyzed using logistic regression analysis.ResultsSerum lipids like TC, TG, LDL-C and ApoB were significantly lower in MSA patients than in controls (TC: 4.31 mmol/Lvs 4.70 mmol/L,P=0.003; TG: 1.17 mmol/Lvs 1.42 mmol/L,P=0.006; LDL-C: 2.66 mmol/Lvs 2.94 mmol/L,P=0.013; ApoA1: 1.17 mmol/Lvs 1.28 mmol/L,P=0.006; ApoB: 0.86 mmol/Lvs 0.92 mmol/L,P=0.021). While, the levels of TG and apoB showed no significant differences between MSA-c patients and controls (P>0.05), and HDL-C level showed no significant differences between MSA-c, MSA-p and controls. The multivariate analysis showed that decreased level of TC, LDL-C, ApoA1 and ApoB were risk factors of MSA.ConclusionThe levels of TC, TG, LDL-C, ApoA1 and ApoB is lower in MSA than in controls, and the decreased level of TC, LDL-c, ApoA1 and ApoB are the risk factors of MSA.%目的 探讨血脂与典型的突触蛋白病多系统萎缩(multiple system atrophy,MSA)的关系.方法 选取2012年4月- 2014年4月就诊于本院的MSA患者113例,选取我院体检的健康人员132例,两组年龄、性别、体质量指数之间差异无统计学意义,观察两组总胆固醇(total cholesterol,TC)、三酰甘油(triglyceride,TG)、低密度脂蛋白(low-density lipoprotein cholesterol,LDL-C)、高密度脂蛋白(high-density lipoprotein cholesterol,HDL-C)以及载脂蛋白A1(apolipoprotein A-1, ApoA1)和载脂蛋白B(apolipoproteins B,ApoB)等变化,

    The present study clones and characterizes the full-length cDNA sequences of members in JAK-STAT pathway, explores their mRNA tissue expression and the biological role in leptin influencing lipid metabolism in yellow catfish Pelteobagrus fulvidraco. Full-length cDNA sequences of five JAKs and seven STAT members, including some splicing variants, were obtained from yellow catfish. Compared to mammals, more members of the JAKs and STATs family were found in yellow catfish, which provided evidence that the JAK and STAT family members had arisen by the whole genome duplications during vertebrate evolution. All of these members were widely expressed across the eleven tissues (liver, white muscle, spleen, brain, gill, mesenteric fat, anterior intestine, heart, mid-kidney, testis and ovary) but at the variable levels. Intraperitoneal injection in vivo and incubation in vitro of recombinant human leptin changed triglyceride content and mRNA expression of several JAKs and STATs members, and genes involved in lipid metabolism. AG490, a specific inhibitor of JAK2-STAT pathway, partially reversed leptin-induced effects, indicating that the JAK2a/b-STAT3 pathway exerts main regulating actions of leptin on lipid metabolism at transcriptional level. Meanwhile, the different splicing variants were differentially regulated by leptin incubation. Thus, our data suggest that leptin activated the JAK/STAT pathway and increases the expression of target genes, which partially accounts for the leptin-induced changes in lipid metabolism in yellow catfish.

    Full Text Available This research aimed at evaluating the effect of diets with high, intermediate and low amylose content of rice on performance, glycemic and lipidic metabolism in rats. Male Wistar rats were fed diets with grains of cooked rice of the cultivars 'IRGA 417', 'IRGA 416' and 'MOCHI' with high, intermediate and low amylose content, respectively. Wet and dry fecal production and serum HDL cholesterol were not affected by amylose content. The animals in the treatments with high amylose content ('IRGA 417' presented lower feed intake, body weight gain and apparent digestibility, higher fecal water content and nitrogen excretion, reduced fecal pH, lower postprandial blood glucose response, serum total cholesterol and triglycerides levels and pancreas weight, and higher fasting serum glucose concentration and liver weight. Amylose:amylopectin ratio significantly affects rice starch digestion in the gastrointestinal tract, affecting some biologically relevant parameters.O objetivo deste trabalho foi avaliar o efeito de dietas com alto, intermediário e baixo teor de amilose sobre o desempenho, metabolismo glicêmico e lipídico em ratos.

  13. Tamoxifen affects glucose and lipid metabolism parameters, causes browning of subcutaneous adipose tissue and transient body composition changes in C57BL/6NTac mice

    International Nuclear Information System (INIS)

    Tamoxifen is a selective estrogen receptor (ER) modulator which is widely used to generate inducible conditional transgenic mouse models. Activation of ER signaling plays an important role in the regulation of adipose tissue (AT) metabolism. We therefore tested the hypothesis that tamoxifen administration causes changes in AT biology in vivo. 12 weeks old male C57BL/6NTac mice were treated with either tamoxifen (n = 18) or vehicle (n = 18) for 5 consecutive days. Tamoxifen treatment effects on body composition, energy homeostasis, parameters of AT biology, glucose and lipid metabolism were investigated up to an age of 18 weeks. We found that tamoxifen treatment causes: I) significantly increased HbA1c, triglyceride and free fatty acid serum concentrations (p < 0.01), II) browning of subcutaneous AT and increased UCP-1 expression, III) increased AT proliferation marker Ki67 mRNA expression, IV) changes in adipocyte size distribution, and V) transient body composition changes. Tamoxifen may induce changes in body composition, whole body glucose and lipid metabolism and has significant effects on AT biology, which need to be considered when using Tamoxifen as a tool to induce conditional transgenic mouse models. Our data further suggest that tamoxifen-treated wildtype mice should be characterized in parallel to experimental transgenic models to control for tamoxifen administration effects. - Highlights: • Tamoxifen treatment causes significantly increased HbA1c, triglyceride and free fatty acid serum concentrations. • Tamoxifen induces browning of subcutaneous AT and increased UCP-1 expression. • Tamoxifen changes adipocyte size distribution, and transient body composition

    Full Text Available Background. Dyslipidemia produces atherosclerosis, which in turn results in coronary artery disease (CAD. Atherosclerosis is being considered as an inflammatory disease. Vaccinium arctostaphylos L. is a plant with fruits rich in anthocyanins. The aim of this study was to evaluate the effects of fruit extract of this plant on serum levels of lipids, hs-CRP, and malondialdehyde (MDA as a marker of oxidative stress, in hyperlipidemic adult patients. Methods. In this randomized, double-blind, placebo-controlled clinical trial, 50 hyperlipidemic adult patients were randomly and equally assigned to receive either medicinal (V. arctostaphylos fruit extract or placebo capsules twice daily for 4 weeks. Each medicinal capsule contained 45 ± 2 mg of anthocyanins. Fasting serum levels of total cholesterol, TG, LDL-C, HDL-C, hs-CRP, and MDA were obtained before and after the intervention and compared. Results. V. arctostaphylos fruit extract significantly reduced total cholesterol (P<0.001, LDL-C (P=0.004, TG (P<0.001, and MDA (P=0.013 compared to placebo but did not have any significant effect on HDL-C (P=0.631 and hs-CRP (P=0.190. Conclusion. Fruit extract of Vaccinium arctostaphylos has beneficial effects on serum lipid profile and oxidative stress in hyperlipidemic adult patients. Therefore, it could be considered as a supplement for treatment of dyslipidemia and prevention of atherosclerosis development.

    Intake of conjugated linoleic acid (CLA) has been demonstrated to beneficially affect risk markers of atherosclerosis and diabetes in rats. CLA is naturally found in milk fat, especially from cows fed a diet high in oleic acid, and increased CLA intake can occur concomitantly with increased milk...... fat intake. Our objective was to investigate the effect of CLA as part of a diet rich in butter as a source of milk fat on risk markers of atherosclerosis, inflammation, diabetes type 11, and lipid peroxidation. A total of 38 healthy young men were given a diet with 115g/d of CLA-rich fat (5.5 g/d CLA...... esters, and phospholipids reflected that of the intervention diets. The CLA diet resulted in increased lipid peroxidation measured as an 83% higher 8-iso-prostaglandin F-2 alpha concentration compared with the control, P...

    Tamoxifen is a selective estrogen receptor (ER) modulator which is widely used to generate inducible conditional transgenic mouse models. Activation of ER signaling plays an important role in the regulation of adipose tissue (AT) metabolism. We therefore tested the hypothesis that tamoxifen administration causes changes in AT biology in vivo. 12 weeks old male C57BL/6NTac mice were treated with either tamoxifen (n = 18) or vehicle (n = 18) for 5 consecutive days. Tamoxifen treatment effects on body composition, energy homeostasis, parameters of AT biology, glucose and lipid metabolism were investigated up to an age of 18 weeks. We found that tamoxifen treatment causes: I) significantly increased HbA1c, triglyceride and free fatty acid serum concentrations (p body composition changes. Tamoxifen may induce changes in body composition, whole body glucose and lipid metabolism and has significant effects on AT biology, which need to be considered when using Tamoxifen as a tool to induce conditional transgenic mouse models. Our data further suggest that tamoxifen-treated wildtype mice should be characterized in parallel to experimental transgenic models to control for tamoxifen administration effects.

    The usefulness of conjugated linoleic acid (CLA) as a nutraceutical remains ambiguous. Our objective was, therefore, to investigate the effect of CLA on body composition, blood lipids, and safety biomarkers in overweight, hyperlipidemic men. A double-blinded, 3-phase crossover trial was conducted in overweight (BMI ≥ 25 kg/m(2)), borderline hypercholesterolemic [LDL-cholesterol (C) ≥ 2.5 mmol/L] men aged 18-60 y. During three 8-wk phases, each separated by a 4-wk washout period, 27 participants consumed under supervision in random order 3.5 g/d of safflower oil (control), a 50:50 mixture of trans 10, cis 12 and cis 9, trans 11 (c9, t11) CLA:Clarinol G-80, and c9, t11 isomer:c9, t11 CLA. At baseline and endpoint of each phase, body weight, body fat mass, and lean body mass were measured by DXA. Blood lipid profiles and safety biomarkers, including insulin sensitivity, blood concentrations of adiponectin, and inflammatory (high sensitive-C-reactive protein, TNFα, and IL-6) and oxidative (oxidized-LDL) molecules, were measured. The effect of CLA consumption on fatty acid oxidation was also assessed. Compared with the control treatment, the CLA treatments did not affect changes in body weight, body composition, or blood lipids. In addition, CLA did not affect the β-oxidation rate of fatty acids or induce significant alterations in the safety markers tested. In conclusion, although no detrimental effects were caused by supplementation, these results do not confirm a role for CLA in either body weight or blood lipid regulation in humans.

    2016-03-01

    Full Text Available Signal transducers and activators of transcription proteins (STATs act as important mediators in multiple biological processes induced by a large number of cytokines. In the present study, full-length cDNA sequences of seven STAT members, including some splicing variants different from those in mammals, were obtained from Synechogobius hasta. The phylogenetic analysis revealed that the seven STAT members were derived from paralogous genes that might have arisen by whole genome duplication (WGD events during vertebrate evolution. All of these members share similar domain structure compared with those of mammals, and were widely expressed across the tested tissues (brain, gill, heart, intestine, liver, muscle and spleen, but at variable levels. Incubation in vitro of recombinant human leptin changed the intracellular triglyceride (TG content and mRNA levels of several STATs members, as well as expressions and activities of genes involved in lipid metabolism. Furthermore, Tyrphostin B42 (AG490, a specific inhibitor of the Janus Kinase 2(JAK2-STAT pathway, partially reversed leptin-induced change on STAT3 and its two spliced isoforms expression, as well as expressions and activities of genes involved in lipid metabolism. As a consequence, the decrease of TG content was also reversed. Thus, our study suggests that STAT3 is the requisite for the leptin signal and the activation of the STAT3 member may account for the leptin-induced changes in lipid metabolism in S. hasta.

    Full Text Available Background: Carnitine is essential for fatty acids translocation, muscles function and exercise performance. Choline is a lipotropic agent that prevents deposition of fat in the liver. The studies concerning the effects of carnitine and choline supplementation with exercise on carnitine status and serum leptin are rare. The aim of the present study was to study the effect of carnitine and its combination with choline, with or without exercise on body and total fat pad (TFP weights, serum carnitine, leptin, -hydroxy butyric acid (-HBA, triacylglycerols (TAG and Free Fatty acids (FFA. Also, total lipids (TL and TAG content of TFP and urinary carnitine were investigated. Material and Methods: 48 male rats were equally divided to the following groups: control (C, carnitine (5 g/Kg diet supplemented, carnitine plus choline (5 and 11.5 g /Kg diet respectively supplemented. Half of each group was subjected to short term aerobic exercise on manual treadmill, in which the speed and duration were gradually increased via the course of the experiment, to be 10 m/min for 20 min/day, 5 days/week in the last 2 weeks. Body weights were recorded weekly. After 6 weeks, The 24 hours urine was collected then the fasted rats were sacrificed and blood and the total fat pad (TFP were collected for analysis. Results: Carnitine supplementation, tended to decrease body weight, TFP, TAG content and serum FFA, and significantly decreased the TL content, serum leptin, TAG (P<0.0005. Carnitine feeding resulted in a significant elevation of serum carnitine, -HBA and urinary carnitine (P<0.0005, compared to sedentary control rats. These values became more pronounced on choline addition to the diet except for serum and urinary carnitine that reversed (i.e. decreased by choline addition. Exercise intervention resulted in a significant decrease in body weight, TFP, TL content and serum leptin, TAG and FFA. These values were more pronounced in both supplements with exercise

    The therapeutical efficiency of verapamil given for 3 months was studied in 36 patients with stable exercise-induced angina by multistep gradually increasing bicycle ergometry exercise test. The effects of the agent on serum lipid levels were evaluated in 30 cases. The therapeutical effect was achieved in 24 patients; verapamil caused a pronounced increase in physical working capacity just during the acute drug test in all cases and showing growing effects within a month of treatment. No increase in therapeutical effects was observed in 12 cases in whom a rise in exercise time was insignificant during the acute drug test. Verapamil produced no noticeable effect on fasting serum glucose and insulin levels after glucose tolerance test in 19 healthy individuals and 11 patients with lower carbohydrate tolerance. Thirteen patients with primary hypercholesterolemia had decreased levels of total cholesterol due to low density lipoprotein cholesterol. PMID:1487877

    Growing evidence suggests that the consumption of dairy products may contribute to a reduced incidence of cardiovascular risk factors, such as obesity, dyslipidemia, and type 2 diabetes. The fatty acid composition in milk fat, the duration of ripening, and the complexity of the food matrices are important factors that may interfere with the physiological impact. In this study, we treated genetic obese and type 2 diabetic mice (db/db) for 4 weeks with different dairy (cheese-based) products, differing by the duration of ripening (0, 15, or 35 days). We found that 35 days ripened product significantly improved glucose tolerance, an effect associated with a decreased adipose tissue lipid peroxide markers (TBARS and NAPDH-oxidase mRNA expression), without affecting body weight, food intake, and fat mass. Both fermented matrices significantly decreased the hepatic lipid content, without modifying plasma triglycerides or plasma total cholesterol. These data suggest that dairy products issued from longer ripening positively impact glucose tolerance, hepatic steatosis, and adipose tissue oxidative stress. Further investigations are warranted to decipher the interactions between milk products fermentation, lipids, and host metabolism. PMID:22300436

  11. Lipid peroxidation in chicken meat during chilled storage as affected by antioxidants combined with low-dose gamma irradiation

    International Nuclear Information System (INIS)

    TBA values and carbonyl content for irradiated samples of ground chicken meat were higher than for nonirradiated samples. Addition of antioxidants tocopherol (natural) or BHT (synthetic) resulted in retardation of oxidative rancidity (p0.05). Meat treated with antioxidants prior to irradiation had lower TBA values as compared to untreated irradiated counterparts. Free fatty acid (FFA) values decreased after irradiation. Addition of antioxidants prior to irradiation showed a synergistic effect in decreasing FFA content. TLC of muscle lipids indicated a reduction in the triacylglcerols content with concomitant increases in FFA of all samples during storage. All irradiated meats were acceptable for consumption up to 4 wk of storage

    2016-01-01

    Here, we studied the effect of the size, shape, and surface charge of Au nanoparticles (AuNPs) on amyloid beta (Aβ) aggregation on a total brain lipid-based supported lipid bilayer (brain SLB), a fluid platform that facilitates Aβ-AuNP aggregation process. We found that larger AuNPs induce large and amorphous aggregates on the brain SLB, whereas smaller AuNPs induce protofibrillar Aβ structures. Positively charged AuNPs were more strongly attracted to Aβ than negatively charged AuNPs, and the stronger interactions between AuNPs and Aβ resulted in fewer β-sheets and more random coil structures. We also compared spherical AuNPs, gold nanorods (AuNRs), and gold nanocubes (AuNCs) to study the effect of nanoparticle shape on Aβ aggregation on the brain SLB. Aβ was preferentially bound to the long axis of AuNRs and fewer fibrils were formed whereas all the facets of AuNCs interacted with Aβ to produce the fibril networks. Finally, it was revealed that different nanostructures induce different cytotoxicity on neuroblastoma cells, and, overall, smaller Aβ aggregates induce higher cytotoxicity. The results offer insight into the roles of NPs and brain SLB in Aβ aggregation on the cell membrane and can facilitate the understanding of Aβ-nanostructure co-aggregation mechanism and tuning Aβ aggregate structures.

    Skin hypersensitivities (allergies) in horses are often diagnosed using clinical signs only. Intradermal testing or serological assays are diagnostic options to confirm the allergic nature of the disease and to identify the allergen(s). Our objective was to develop an allergen-specific enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody specific for horse IgE and to examine its potential for allergen detection in serum in comparison to intradermal testing. Intradermal testing with 61 allergen extracts was performed on 10 horses affected with skin hypersensitivity. Their sera were analyzed by ELISA for IgE antibodies to the same allergens. The kappa test of concordance was used for comparison of the results of both tests. Out of 61 allergen extracts, only two (Timothy and Quack) had kappa values greater than 0.60, suggesting a substantial agreement between skin testing and IgE ELISA. The statistical comparison of the remaining 59 allergens showed little or no concordance between the tests beyond chance. To identify parameters that may influence the sensitivity of the ELISA, the assay was modified to detect allergen-specific IgGb and IgG(T) in serum, and the protein content in all allergen extracts was determined by SDS-PAGE. The commercial allergen extracts revealed a high variation in detectable protein. High concentrations of allergen-specific IgG in horse serum were found to compete with IgE for binding to the plates. In conclusion, an ELISA using whole serum and crude allergen preparations provides limited diagnostic information in horses. The reliable diagnosis of allergens in equine skin hypersensitivity is essential to improve allergen-specific treatments, such as hyposensitization, or the development of allergy vaccines.

    Background. Dyslipidemia has been well-known as a common metabolic disorder contributing to cardiovascular disease. The aim of this study was to evaluate the effect of the Pinus koraiensis needle extracts (PKE) on the blood cholesterol and oxidative stress. Method. We conducted a 12-week randomized, double-blinded controlled trial to examine the effect of PKE on blood lipid profiles in adults with borderline dyslipidemia. Thirty-three eligible persons were recruited and randomly assigned into PKE (n = 20) and placebo groups (n = 13). Serum lipids including total cholesterol, low-density lipoprotein- (LDL-) cholesterol, high-density lipoprotein- (HDL-) cholesterol, very low-density lipoprotein- (VLDL-) cholesterol, and triglyceride were measured before and after trial. Serum insulin, glucose, and antioxidant indicators were also analyzed before and after trial and anthropometry and blood pressure were measured every 4 weeks. Results. After 12 weeks, PKE statically significant decreases in systolic blood pressure (p effective in improving the superoxide dismutase in the individuals with borderline dyslipidemia. PMID:27610187

    The aim of the study was to investigate the ability of γ-tocopherol, ethylenediaminetetraacetate (EDTA), and ascorbyl palmitate to protect fish oil enriched salad dressing against oxidation during a 6 week storage period at room temperature. The lipid-soluble γ-tocopherol (220 and 880 µg g-1 of...... antioxidant, and overall peroxide values and volatiles were reduced by approximately 70 and 77-86%, respectively. Conversely, prooxidant effects were observed with a high concentration of ascorbyl palmitate (300 µg g-1 of fish oil), whereas a low concentration was slightly antioxidative (50 µg/g of fish oil......). Finally, a combination of all three antioxidants completely inhibited oxidation during storage, indicating that the prooxidant effects of ascorbyl palmitate were reverted or overshadowed by EDTA and γ-tocopherol....

    Full Text Available Abstract Background Visceral fat accumulation is one of the most important predictors of mortality in obese populations. Administration of green tea extract (GTE can reduce body fat and reduce the risk of obesity-related diseases in mammals. In this study, we investigated the effects and mechanisms of GTE on adiposity in diet-induced obese (DIO zebrafish. Methods Zebrafish at 3.5 to 4.5 months post-fertilization were allocated to four groups: non-DIO, DIO, DIO + 0.0025%GTE, and DIO + 0.0050%GTE. The non-DIO group was fed freshly hatched Artemia once daily (5 mg cysts/fish daily for 40 days. Zebrafish in the three DIO groups were fed freshly hatched Artemia three times daily (60 mg cysts/fish daily. Zebrafish in the DIO + 0.0025%GTE and DIO + 0.0050%GTE groups were exposed to GTE after the start of feeding three times daily for 40 days. Results Three-dimensional microcomputed tomography analysis showed that GTE exposure significantly decreased the volume of visceral but not subcutaneous fat tissue in DIO zebrafish. GTE exposure increased hepatic expression of the lipid catabolism genes ACOX1 (acyl-coenzyme A oxidase 1, palmitoyl, ACADM (acyl-coenzyme A dehydrogenase, c-4 to c-12 straight chain, and PPARA (peroxisome proliferator-activated receptor alpha. GTE exposure also significantly decreased the visceral fat expression of SOCS3 (suppressor of cytokine signaling 3b which inhibits leptin signaling. Conclusions The present results are consistent with those seen in mammals treated with GTE, supporting the validity of studying the effects of GTE in DIO zebrafish. Our results suggest that GTE exerts beneficial effects on adiposity, possibly by altering the expression of lipid catabolism genes and SOCS3.

    The aim of the present study was to examine whether high intake of lean or fatty fish (cod and farmed salmon, respectively) by healthy, normal-weight adults would affect risk factors of type 2 diabetes and CVD when compared with lean meat (chicken). More knowledge is needed concerning the potential health effects of high fish intake (>300 g/week) in normal-weight adults. In this randomised clinical trial, thirty-eight young, healthy, normal-weight participants consumed 750 g/week of lean or fatty fish or lean meat (as control) for 4 weeks at dinner according to provided recipes to ensure similar ways of preparations and choices of side dishes between the groups. Energy and macronutrient intakes at baseline and end point were similar in all groups, and there were no changes in energy and macronutrient intakes within any of the groups during the course of the study. High intake of fatty fish, but not lean fish, significantly reduced TAG and increased HDL-cholesterol concentrations in fasting serum when compared with lean meat intake. When compared with lean fish intake, fatty fish intake increased serum HDL-cholesterol. No differences were observed between lean fish, fatty fish and lean meat groups regarding fasting and postprandial glucose regulation. These findings suggest that high intake of fatty fish, but not of lean fish, could beneficially affect serum concentrations of TAG and HDL-cholesterol, which are CVD risk factors, in healthy, normal-weight adults, when compared with high intake of lean meat.

    Full Text Available OBJECTIVES: Dyslipidemia is one of the important modifiable risk factors for cardiovascular disease. Thus, to know the prevalence of dyslipidemia is the 1(st step to make guidelines of screening and management plan. Although, American Academy of Pediatrics updated the guidelines for lipid in childhood, Asian study is rare. METHODS: The authors aimed to make a reference of each serum lipid level of Korean children and adolescents (2,363 subjects aged 10 to 18 years from the data of Korea National Health and Nutrition Examination Survey IV (2007-2009. RESULTS: The mean serum concentrations for total cholesterol (TC, low-density lipoprotein cholesterol (LDL-C, triglycerides (TG, and high-density lipoprotein cholesterol (HDL-C were 158 mg/dL, 90 mg/dL, 90 mg/dL, and 49 mg/dL, respectively. The 95th percentile values for TC, LDL-C, and TG were 203 mg/dL, 129 mg/dL, and 185 mg/dL, respectively. The 5th percentile value for HDL-C was 36 mg/dL. The prevalence of hypercholesterolemia, high LDL-C, high TG, and low HDL-C was 6.5%, 4.7%, 10.1%, and 7.1%, respectively. Considering the risk factors such as obesity, hypertension, smoking, and diabetes, approximately 0.41% of the subjects were potentially eligible for pharmacological treatment. CONCLUSIONS: This information may be useful in not only Korean but also Asian planning programs for the prevention of cardiovascular disease through lipid control from childhood.

    Ethanol or acetone inhalation resulted in a reduction in motor activity in rats, affecting largely their explorative behavior. The biochemical parameters of free-radical processes (catalyse and SOD activities, LPO levels) remained unchanged in the inhaling animals. Ethanol or acetone inhalation caused a significant decrease in blood catalyse activity and serum LPO levels. The acetone- and ethanol-induced changes in the activity of ceruloplasmin were heterodirectional. It can be concluded that it is useful to study the biochemical parameters of serum free-radical processes and to employ the findings in the therapy of inhalation toxicomanias.

    Transmembrane kinases of Entamoeba histolytica are known to play a wide range of roles from virulence, phagocytosis, and proliferation to stress response. Transmembrane kinase EhTMKB1-9 is thought to be involved in early proliferative response and it was originally identified as a serum inducible gene. Ability to stimulate EhTMKB1 expression of serum starved cells resides in unsaturated fatty acids associated with albumin fraction of serum and the mechanism of stimulation follows activation of EhTMKB1-9 promoter. Gel shift assay showed the presence of proteins that bind to the specific site of EhTMKB1-9 upstream region and the concentration of these protein(s) go down on serum starvation, but level of binding protein(s) go up on serum or fatty acid replenishment. This increase in concentration of binding molecule(s) is due to new synthesis rather than activation of existing molecule(s) as a protein synthesis inhibitor blocked enhanced level of gel shifted material on replenishment. The stimulating activity resides in the fatty acyl chain, but not in the head group. Moreover, the fatty acid initiates signaling through class I PI3 kinases that result in activation of EhTMKB1-9 expression. These results suggest a novel mechanism of gene regulation in E. histolytica, and unsaturated fatty acids as potential new signaling molecules.

    The prevalence of autism spectrum disorders (ASDs) has been on the rise over recent years. The presence of diverse subsets of candidate genes in each individual with an ASD and the vast variability of phenotypical differences suggest that the interference of an exogenous environmental component may greatly contribute to the development of ASDs. The lipid mediator prostaglandin E2 (PGE2 ) is released from phospholipids of cell membranes, and is important in brain development and function; PGE2 is involved in differentiation, synaptic plasticity and calcium regulation. The previous review already described extrinsic factors, including deficient dietary supplementation, and exposure to oxidative stress, infections and inflammation that can disrupt signaling of the PGE2 pathway and contribute to ASDs. In this review, the structure and establishment of two key protective barriers for the brain during early development are described: the blood-brain barrier; and the placental barrier. Then, the first comprehensive summary of other environmental factors, such as exposure to chemicals in air pollution, pesticides and consumer products, which can also disturb PGE2 signaling and increase the risk for developing ASDs is provided. Also, how these exogenous agents are capable of crossing the protective barriers of the brain during critical developmental periods when barrier components are still being formed is described. This review underlines the importance of avoiding or limiting exposure to these factors during vulnerable periods in development.

    In this study, different light intensities (80, 160, 240 and 320 μmol/m(2) s) and various mediums including control medium (CM), N/P rich medium (NPM), N rich medium (NM), and P rich medium (PM) were applied for cultivation of Chlorella sp. It was revealed that cultivation of Chlorella sp. in CM under the light intensity of 320 μmol/m(2) s led to a lipid content up to 30% enhancement, which was higher than the results of other cases. A rather high unsaturated fatty acid (UFA) content of 7.5% and unsaturated fatty acid/total fatty acid (UFA/TFA) ratio of 0.73 were obtained under 320 μmol/m(2) s in CM, indicating that the CM-320 system was applicable for the generation of UFA. Moreover, Chlorella sp. cultivated in PM under 320 μmol/m(2) s provided higher TFA content (7.3%), which was appropriate for biofuel production.

    There is a broad need to reformulate lower sodium food products without affecting their original taste. The present study focuses on characterizing the role of protein-salt interactions on the salt release in low-moisture systems and saltiness perception during hydration. Sodium release from freeze-dried protein powders and emulsion powders formulated at different protein/lipid ratios (5:0 to 1:4) were characterized using a chromatography column modified with a porcine tongue. Emulsion systems with protein structured at the interface were found to have faster initial sodium release rates and faster hydration and were perceived to have a higher initial salt intensity with a lower salty aftertaste. In summary, exposure of the hydrophilic segments of the interface-structured proteins in emulsions was suggested to facilitate hydration and release of sodium during dissolution of low-moisture powder samples.

Methods A cross-section study on 1 441 metallurgical mill workers was conducted and their serum lipids were measured. Results Workers exposed to noise combining with hot environment and single noise had higher total cholesterol (TC) level (P<0.05)in some age groups.Workers exposed to single noise had a higher TG than that exposed to noise combined with hot environment at the same scale of accumulative noise dose.The non-conditional logistic regression model indicated that accumulative noise dose appeared to be an independent risk factors for high serum TC.Scale of hot environment seemed to be a protective factor of high TC after controlling for several potential confounding factors(age,BMI).The multiple liner regression model indicated that serum TC level was significantly associated with accumulative noise dose,but negative associate with scale of hot environment. Conclusion The result indicated that workers exposed to noise in long term might induce high lipidemia.

    The main dietary guidelines recommend restricting total and saturated fat intake in the management of high blood cholesterol levels for cardiovascular risk. These recommendations are usually oversimplified by considering that all red meats should be limited and replaced by white meats. However, lean red meat can be as low in fat as white meat. We examined the effects of red meat (lean breed lamb) and lean white meat (chicken) intake on the lipid profile of a group of women with stable life conditions (nuns living in convents). An open-label, randomised, cross-over study was carried out in thirty-six nuns who consumed either lamb or chicken three times per week for 5-week periods with their usual diet. Clinical, dietary and biochemical variables were evaluated at baseline and the end of each diet period. A validated FFQ was used to assess nutrient intake and monitor compliance. The results showed neither between-diet differences in lipid responses nor differences from baseline in total cholesterol, LDL-cholesterol or TAG for any diet period. In conclusion, consumption of lean red meat (lamb) or lean white meat (chicken) as part of the usual diet is associated with a similar lipid response. These two foods can be exchanged in a healthy diet to increase palatability. PMID:21902857

    Background. Dyslipidemia has been well-known as a common metabolic disorder contributing to cardiovascular disease. The aim of this study was to evaluate the effect of the Pinus koraiensis needle extracts (PKE) on the blood cholesterol and oxidative stress. Method. We conducted a 12-week randomized, double-blinded controlled trial to examine the effect of PKE on blood lipid profiles in adults with borderline dyslipidemia. Thirty-three eligible persons were recruited and randomly assigned into PKE (n = 20) and placebo groups (n = 13). Serum lipids including total cholesterol, low-density lipoprotein- (LDL-) cholesterol, high-density lipoprotein- (HDL-) cholesterol, very low-density lipoprotein- (VLDL-) cholesterol, and triglyceride were measured before and after trial. Serum insulin, glucose, and antioxidant indicators were also analyzed before and after trial and anthropometry and blood pressure were measured every 4 weeks. Results. After 12 weeks, PKE statically significant decreases in systolic blood pressure (p < 0.05) and waist circumference (p < 0.05) were observed. Also, VLDL-cholesterol significantly decreased (from 24.4 ± 10.0 mg/dL at baseline to 18.4 ± 4.1 mg/dL after 12 weeks) (p < 0.05) and superoxide dismutase (SOD) increased (6.12 ± 0.41 U/mL to 9.06 ± 0.62 U/mL) (p < 0.01) in PKE group. However, after adjustment with WC, VLDL-cholesterol was not significant between groups (p = 0.095) and while SOD remained significant between groups (p = 0.013). Conclusion. The results show that PKE was effective in improving the superoxide dismutase in the individuals with borderline dyslipidemia.

    Full Text Available Background. The use of statins is essential for aggressive lipid-lowering treatment in acute coronary syndrome (ACS patients with dyslipidemia. Recently, elevation of sitosterol, a lipid absorption marker, was reported to be associated with premature atherosclerosis. The purpose of the present study was to examine the impact of ezetimibe, a selective intestinal cholesterol transporter inhibitor, in ACS patients. Methods. A total of 197 ACS patients were randomized to pitavastatin + ezetimibe (n=100 or pitavastatin (n=97. Low-density lipoprotein cholesterol (LDL-C and sitosterol levels were evaluated on admission and after 12 weeks. Results. After 12 weeks, the pitavastatin + ezetimibe group showed a significantly greater decrease of sitosterol (baseline versus after 12 weeks; 2.9 ± 2.5 versus 1.7 ± 1.0 ng/mL, P<0.001 than the pitavastatin group (2.7 ± 1.5 versus 3.0 ± 1.4 ng/mL. The baseline sitosterol level was significantly higher in patients with achieved LDL-C levels ≥ 70 mg/dL than in patients with levels < 70 mg/dL (3.2 ± 2.5 versus 2.4 ± 1.3 ng/mL, P=0.006. Conclusions. Ezetimibe plus statin therapy in ACS patients with dyslipidemia decreased LDL-C and sitosterol levels more than statin therapy solo. Sitosterol Elevation was a predictor of poor response to aggressive lipid-lowering treatment in ACS patients.

    Full Text Available Noni fruit is a medicinal plant with biological activity like antioxidant that could potentially be used as a feed additive in poultry. This research investigated the effect of noni fruit powder as feed additive on lipid profiles of blood and meat fatty acid compositions of meat of hybrid duck. One hundred twenty 2-week-old hybrid ducks crossing between Peking and Khaki Campbell duck were subjected. They were randomly allotted to 24 experimental units. Each experimental unit was 70x80x40 cm in size and it was used for 5 ducks up to they reached 56 days of age. Each unit was equipped with waterer and feeder. The ducks were raised on litter-type floor. The basal experimental diet was formulated according to the standards of National Research Council (1994. The method used for this study was experimental with 4 different treatments in 6 replications. The treatments were as follow: P0: basal feed without supplementation of noni fruit powder as control; P1: basal feed + 1 % noni fruit powder; P2: basal feed + 2 % noni fruit powder; P3: basal feed + 3 % noni fruit powder. Data were analyzed by one-way of Completely Randomized Design ANOVA and if there was significant effect followed by Duncan’s Multiple Range Test. Result showed that using noni fruit powder as feed additive had no significant effect (P>0.05 on lipid profiles of blood and fatty acid composition of meat.

    The present study was designed to evaluate the effect of Plantago major Linnaeus (PM) extract on serum total sialic acid (TSA), lipid-bound sialic acid (LSA), some trace elements (copper (Cu), zinc (Zn) and iron) and mineral levels (magnesium, calcium and sodium) in Wistar albino rat administrated 7,12-dimethylbenz(a)anthracene (DMBA). Rats were divided into three equal groups (n = 6). Group I comprised the control group, group II was treated with DMBA (100 mg/kg, single dose) and group III was treated with DMBA (100 mg/kg single dose) and aqueous extract of PM 100 mg/kg/day for 60 days. After 60 days, statistical analyses showed that TSA and LSA levels in DMBA and DMBA + PM groups were significantly higher compared to the control group (TSA: p < 0.01, p < 0.05; LSA: p < 0.05, p < 0.05, respectively). Serum Zn levels were decreased in subjects treated with DMBA (p < 0.01) and DMBA + PM (p < 0.05) compared to the control group values. Serum Cu levels were increased in DMBA group and PM-treated group compared to the control group values. The results of this investigation showed that the levels of TSA and LSA changed significantly, which are sensitive markers for detecting the toxic effects of DMBA. On the other hand, observed decline in Zn levels in rats from DMBA + PM group might be due to decreased generation of free radicals and oxidative stress. Results from this study suggest that PM may be partially effective in preventing carcinogenesis initiated by environmental carcinogen DMBA. PMID:21996710

After 7 or 20 infusions, free cholesterol (FC) and phospholipids (PL) were strongly increased, and HDL-cholesterol (HDL-C), apoA-I, and apoA-II were strongly decreased. We then measured short-term effects on apoA-IM, lipids, and (apo)lipoproteins after the first or the last infusion. After the first infusion, PL and FC went up in the HDL region and also in the LDL and VLDL regions. ApoE shifted from HDL to LDL and VLDL regions, while ApoA-IM remained located in the HDL region. On day 41, ApoE levels were 8-fold higher than on day 1, and FC, PL, and apoE resided mostly in LDL and VLDL regions. Drug infusion quickly decreased the endogenous cholesterol esterification rate. ABCA1-mediated cholesterol efflux on day 41 was markedly increased, whereas scavenger receptor type B1 (SRB1) and ABCG1-mediated effluxes were only weakly increased. Strong increase of FC is due to sustained stimulation of ABCA1-mediated efflux, and drop in HDL and formation of large apoE-rich particles are due to lack of LCAT activation. PMID:23828780

    Objective To investigate whether the presence of lymph node metastases is associated with serum triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), LDL-C/HDL-C ratio and total cholesterol (TC). Methods Serum lipid profile and various clinical pathological data of 207 breast cancer patients with and without lymph node metastases were collected and analyzed to investigate the association of serum lipid profile with lymph node metastases. Statistical analyses were performed using the t test and Pearson's Chi-Square test. Results Lymph node metastases rate was significantly higher in breast cancer patients with an higher level of serum TG (P=0.03) and LDL-C/HDL-C ratio (P=0.03). No significant difference was found in serum TC, LDL-C or HDL-C levels. The two groups had no difference in age, menopausal status, BMI index, IHC type and other clinical pathological features (P>0.05). Conclusion Increased TG and LDL-C/HDL-C ratio is significantly associated with lymph node metastases in breast cancer patients. Monitoring TG and LDL-C/HDL-C ratio may be helpful to predict the occurrence of lymph node metastases in breast cancer patients.%目的:通过测定乳腺癌患者的多项血脂指标,包括甘油三酯(triglycerides, TG),低密度脂蛋白胆固醇(low-density lipoprotein cholesterol, LDL-C),高密度脂蛋白胆固醇(high-density lipoprotein cholesterol, HDL-C),LDL-C/HDL-C比值和血清总胆固醇(total cholesterol, TC),探讨不同乳腺癌患者血脂水平与乳腺癌淋巴结转移之间的关系。方法收集207例经病理确诊的乳腺癌患者清晨空腹多项血脂数据及临床病理资料,定量数据采用t检验,定性数据采用χ2检验,分析患者的各项血脂数据与淋巴结转移间的关系。结果淋巴结高转移患者的TG水平(P=0.03)及LDL/HDL比值(P=0.03)均高于淋巴结低转移组;而两组患者的TC、LDL-C及HDL-C水

    Full Text Available Abstract Background The α-isoform of the Type 1A Phosphoinositide 3-kinases (PI3Kα has protein kinase activity as well as phosphoinositide lipid kinase activity. The best described substrate for its protein kinase activity is its regulatory subunit, p85α, which becomes phosphorylated on Serine 608. Phosphorylation of Serine 608 has been reported to down-regulate its lipid kinase activity. Results We have assessed whether oncogenic mutants of PI3Kα, which have up-regulated lipid kinase activity, have altered levels of Serine 608 phosphorylation compared to wild type PI3Kα, and whether differential phosphorylation of Serine 608 contributes to increased activity of oncogenic forms of PI3Kα with point mutations in the helical or the kinase domains. Despite markedly increased lipid kinase activity, protein kinase activity was not altered in oncogenic compared to wild type forms of PI3Kα. By manipulating levels of phosphorylation of Serine 608 in vitro, we found no evidence that the protein kinase activity of PI3Kα affects its phosphoinositide lipid kinase activity in either wild-type or oncogenic mutants of PI3Kα. Conclusions Phosphorylation of p85α S608 is not a significant regulator of wild-type or oncogenic PI3Kα lipid kinase activity.

    ,visfatin level,bone mineral density(BMD) and bone metabolism index respectively. Results:Cholesterol total( CHOL) contents and visfatin levels in blood serum of osteoporosis patients were all higher than those of osteopenia patients (< = -2. 481 ,P = 0. 016;( =-2. 850, P -0.006). Both serum CHOL level and serum visfatin level were correlated negatively with BMD(r= -0. 524,P=0.000;r = -0.523,P = 0.000) and were correlated positively with the level of tartrate-resistant acid phosphatase( r=0.426,P =0.001 ;r =0.674,P =0.000) and had no correlations with the level of bone alkaline phosphatase(r= -0. 208,P = 0. 110;r = -0. 240, P = 0.065). Conclusion: As there-suit of lipid metabolism disorders, elevated levels of serum CHOL and abnormal expression of visfatin may have effects on PMOP attack through affecting bone metabolism and speeding up bone absorption,however,the concrete mechanism shoule be further studied.

    Full Text Available Abstract Objectives Accumulating evidence suggested that dysregulation of cholesterol homeostasis might be a major etiologic factor in initiating and promoting neurodegeneration in Alzheimer’s disease (AD. ATP-binding cassette transporter A1 (ABCA1, hepatic lipase (HL, coding genes named LIPC and cholesteryl ester transfer protein (CETP are important components of high-density lipoprotein (HDL metabolism and reverse cholesterol transport (RCT implicated in atherosclerosis and neurodegenerative diseases. In the present study, we will investigate the possible association of several common polymorphisms (ABCA1R219K, CETPTaqIB and LIPC-250 G/A with susceptibility to AD and plasma lipid levels. Methods Case–control study of 208 Han Chinese (104 AD patients and 104 non-demented controls from Changsha area in Hunan Province was performed using the PCR-RFLP analysis. Cognitive decline was assessed using Mini Mental State Examination (MMSE as a standardized method. Additionally, fasting lipid profile and the cognitive testing scores including Wechsler Memory Scale (WMS and Wisconsin Card Sorting Test (WCST were recorded. Results and conclusions We found significant differences among the genotype distributions of these three genes in AD patients when compared with controls. But after adjusting other factors, multivariate logistic regression analysis showed only ABCA1R219K (B = −0.903, P = 0.005, OR = 0.405, 95%CI:0.217-0.758 and LIPC-250 G/A variants(B = −0.905, P = 0.018, OR = 0.405, 95%CI:0.191-0.858 were associated with decreased AD risk. There were significantly higher levels of high-density lipoprotein cholesterol (HDL-C and apolipoproteinA-I in the carriers of KK genotype and K allele (P F = 5.598, P = 0.004, while -250 G/A polymorphisms had no significant effect on HDL-C. In total population, subjects carrying ABCA1219K allele or LIPC-250A allele obtained higher MMSE or WMS scores than non-carriers, however

    Full Text Available Objective(s: Leptin exerts various effects on appetite and body weight. Disruption of the obesitygene is precedent to fatness. Insulin or glucose elevates leptin, but streptozotocin reduces it. However, controversial data exist for the effects of leptin on diabetes and leptin level in each gender. Leptin can damage the kidney function but little evidence exists for its hepatic effects. The aim of this study was to investigate the probable sex-dependent differences in blood sugar levels, lipid profile, and renal and hepatic biochemical factors in the obesity and streptozotocin-induced diabetic rats after leptin administration. Materials and Methods: Wistar rats of both sexes were randomly divided into two groups, namely obese and diabetic rats. Each group was further divided into male and female subgroups. Extra fat and carbohydrate was added to the diet to induce obesity. Furthermore, streptozotoc
