    Chromium deficiency may cause insulin resistance, hyperinsulinemia, impaired glucose tolerance, and hyperlipidemia, recovered by chromium supplementation. The effect of chromium supplementation on serum lipids and glucose tolerance was tested in a double-blind 12-wk study of 23 healthy adult men aged 31 to 60 yr. Either 200 micrograms trivalent chromium in 5 ml water (Cr) or 5 ml plain water (W) was ingested daily 5 days each week. Half the subjects volunteered for glucose tolerance tests with insulin levels. At 12 wk high-density lipoprotein cholesterol increased in the Cr group from 35 to 39 mg/dl (p less than 0.05) but did not change in the water group (34 mg/dl). The largest increase in high-density lipoprotein cholesterol and decreases in insulin and glucose were found in those subjects having normal glucose levels together with elevated insulin levels at base-line. The data are thus consistent with the hypothesis that Cr supplementation raises high-density lipoprotein cholesterol and improves insulin sensitivity in those with evidence of insulin resistance but normal glucose tolerance.

    Apolipoprotein E (ApoE), which has been shown to influence serum lipid parameters, can bind to multiple types of lipids and plays an important role in the metabolism and homeostasis of lipids and lipoproteins. A previous study showed that ApoE concentration significantly affects serum lipid levels independently of ApoE polymorphism. The serum lipid levels were also closely correlated with dietary habits, and Shandong cuisine is famous for its high salt and oil contents, which widely differ among the different areas in China. Therefore, studying the effect of ApoE polymorphism on ApoE concentration and serum lipid levels in Shandong province is very important.A total of 815 subjects including 285 men and 530 women were randomly selected and studied from Jinan, Shandong province. In order to evaluate the association of ApoE polymorphism and serum level on lipid profiles, the ApoE genotypes, as well as levels of fasting serum ApoE and other lipid parameters, were detected in all subjects.The frequency of the ApoE E3 allele was highest (83.1%), while those of E2 and E4 were 9.4% and 7.5%, respectively, which are similar to those in other Asian populations. ApoE2 allele carriers showed significantly increased ApoE levels but lower levels of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and Apolipoprotein B (ApoB).We found that ApoE level is influenced by ApoE polymorphism in a gene-dependent manner. The ApoE polymorphism showed different influences on serum lipid parameters with increasing age and body mass index (BMI) in our Shandong Han population.

    To compare serum lipid profile between patients of ischaemic and haemorrhagic strokes. Study Design: Cross sectional, comparative study. Place and Duration of Study: Military Hospital, Rawalpindi, from August 2004 to February 2005. Methodology: Patients with diagnosis of stroke comprising 100 consecutive patients each of ischaemic and haemorrhagic strokes were included in the study while patients on lipid lowering therapy were excluded from study. To determine the subtype of stroke, clinical examination followed by CT scan of brain was done. A serum sample after 8 hours of overnight fasting was taken on the next day of admission for both groups of patients. Total serum cholesterol, triglycerides, LDL cholesterol, VLDL-cholesterol and HDL-cholesterol was determined, using enzymatic colorimetric method. Statistical analysis was done by comparison of lipid profile in two subgroups, using proportion test for any significant difference. Results: The mean age at presentation of patients with stroke was 64.2+-12 years with a male to female ratio of 3.6:1. In 100 ischaemic stroke patients, raised serum total cholesterol was seen in 42, triglyceride in 04, LDL-cholesterol in 05 and VLDL-cholesterol in 07 patients. Serum HDL-cholesterol was below the normal reference in 31 cases. On the other hand, serum total cholesterol and triglycerides was raised in 05 patients each, LDL-cholesterol in 09 and VLDL-cholesterol in 03 patients of haemorrhagic stroke. Serum HDL-cholesterol was below normal in 04 patients of haemorrhagic stroke. On comparison, there were significantly greater number of patients with raised serum cholesterol and low HDL-cholesterol in ischaemic stroke than haemorrhagic stroke (p < 0.05). No statistical significance was found on comparing serum values of ischaemic and haemorrhagic stroke for triglycerides, LDL-cholesterol and VLDL-cholesterol. Conclusion: Ischaemic stroke patients had high serum total cholesterol and lower HDL-cholesterol levels as compared to

    The aim of the present study was to investigate the association between coffee consumption and serum lipid levels in a study population of 122 Turkish subjects (mean age, 41.4±12.69 years), including 48 males and 74 females. A questionnaire was compiled to determine baseline characteristics, and food and coffee consumption. Subjects were divided into three groups, which included non-drinkers, Turkish coffee and instant coffee drinkers, and anthropometric measurements were acquired, including weight, height and body mass index. Serum lipid levels were analyzed, including the total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) levels. Of the population studied, 76.2% had consumed at least one cup of coffee per week over the previous year. Daily consumption values were 62.3±40.60 ml (0.7±0.50 cup) for Turkish coffee and 116.3±121.96 ml (0.7±0.81 cup) for instant coffee. No statistically significant differences were observed in the serum levels of TC, TG, LDL-C, HDL-C or VLDL-C among the three groups. In addition, no statistically significant differences were observed in the serum lipid levels when comparing individuals who consumed coffee with sugar/cream or who smoked and those who did not (P>0.05). Therefore, the present observations indicated no significant association between the consumption of Turkish or instant coffee and serum lipid levels.

    Psoriasis is a common chronic and recurrent inflammatory skin disorder characterized by hyperproliferation of keratinocytes and infiltration of T cells, monocytes/macrophages and neutrophils into dermal and epidermal layers of the skin. The prevalence of cardiovascular disorders in these patients is remarkably higher compared to normal individuals, which seems to be associated with the hyperlipidemia. This study was designed and conducted to investigate the serum lipid profile in psoriatic patients and its association with the severity of disease. This case-control study was performed on 50 plaque-type psoriasis patients and 50 healthy individuals as control, matched for age and sex. Blood samples were collected after 14 h fasting. Serum triglyceride, cholesterol and lipoproteins were assayed using the standard kit (made by Pars Azmon Co. Iran). Certain parameters, including serum triglyceride, cholesterol, low density lipoprotein (LDL), and very low density lipoprotein (VLDL), were significantly higher in the case group compared to the controls (P lipoprotein (HDL) was significantly lower in the former (P < 0.001). In addition, there was a significant relationship between severity of psoriasis and serum lipid profile. The results have revealed the higher plasma level of lipids in psoriatic patients. This may elevate the risk of atherosclerosis, particularly cardiovascular disorders. Therefore, from the epidemiological point of view, screening psoriatic patients, particularly those with severe psoriasis, is recommended.

    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.

    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

    With blood obtained from patients irradiated for cervical uterine cancer (consisting of 4 cases of Stage I, 5 cases of Stage II and 4 cases of Stage III), changes of blood picture, serum lipid weight and serum lipid peroxide accompanying irradiation were studied on 3 occasions, before, during and after the irradiation. The following results were obtained. Serum lipid and serum lipid peroxide were found to increase along with the advance of uterine cancer from Stage I to II and III. At the termination of irradiation the serum lipid and serum lipid peroxide in the cases of cervical uterine cancer at Stage III were found to have recovered to close to the levels before irradiation, but in the other cases these values tended to increase with irradiation. Except the termination of irradiation treatment of cervical uterine cancer of Stage III, the decrease of leucocyte count has a mutual relationship with the increase of serum thiobarbituric acid (TBA), so that change in the serum TBA level can be assumed to be a criterion for irradiation injury.

    Rabbits were irradiated once with 1000R over the whole body, and the following results were obtained. 1) The whole lipid content of serum: The whole lipid content was found to have increased about 2.6 times 24 hours after irradiation, and even after a lapse of 48 hours such a tendency persisted. 2) Serum whole TBA level: 24 hours after irradiation the whole TBA level had increased markedly up to about 6.5-fold of that before irradiation. 3) Lipid content of fraction: Especially marked in the increase in triglyceride. 4) TBA level of fractionated lipid: There is seen a marked increase in cholesterol ester, which practically occupied the entire serum TBA value. Next marked was the increase in phospholipid, and quantitatively it was classified that the increases seen in triglyceride and free fatty acids are not concerned with the rise in the free fatty acid content and TBA level. 5) Serum lipid contents and TBA level in fasting: By taking the level of serum lipid 24 hours after the start of fasting as one, the serum lipid levels were studied at 48 and 72 hours after the start of fasting, and it was found that both serum lipid and TBA levels rose only very slightly. 6) Changes in fatty acids: The relative ratio of palmitic acid to the whole fatty acids increased after irradiation, and the ratios of linolic acid and linolenic acid were decreased by irradiation while by 48 hours the relative ratio of linolic acid was decreased to about 1/5 of that before irradiation, and the relative ratio of linolenic acid was markedly decreased to about 1/35.

    Full Text Available The aim of this paper was to prove the relation between serum lipid values (cholesterol, trig- lyceride, low density cholesterol, high density cholesterol and primary open -angle glaucoma. The study includes two patient groups: 50 patients with primary open-angle glaucoma and 50 patients without this disease. However, all 100 patients were tested for serum lipid values. The research covered a period of six months (from May to December 2007.. Primary open-angle glaucoma was diagnosed with intraocular pressure values (between 20,1 and 25,6 mm Hg measured with Schiotz tonometry. The visual field changes were confirmed with Goldmann perimetry. The gonioscopies were done for diagnosis confirmation. The serum lipid values were confirmed with enzymatic colorimetry in vitro method. U-test (Mann-Witney-Wilcox test and t-test, as nonparametric tests, were used for statistical evaluations. The cholesterol mean value in the test group was 6,14 mol/dm1 (3,20-8,10 mol/dm3 whereas in the control group it was 5,96 mol/dm3 (2,70-8,80 mol/dm3. U-test was with negative ranks (z=-0,83 AS=0,678. The triglyceride mean value in the test group was 2,38 mol/dm3 (0,84-11,73 mol/m3 and in the control group it was 2,04 mol/dm3 (0,63-5,89 mol/dm3. U-test was with positive ranks (z=0,950 AS=0,342. High density cholesterol was average in the test group with 1,45 mol/dm3 (0,71-3,40 mol/dm3 and in the control group 1,40 mol/m3 (0,80-3,20 mol/dm3. Low density cholesterol in the test group was 3,98 mol/m3 (1,82-6,49 mol/m3 and in the control group 4,08 mol/m3 (2,69-5,69 mol/m3. These results had positive ranks according to U-test. Serum lipid values could be one of predictable factors in primary open-angle glaucoma diagnosis. Due to the patient age, cholesterol values, as common factors in primary open-angle glaucoma and atherosclerosis genesis, could be concern in the same aetiology based on dyslipidaemia as well.

    1987-01-01

    The effects of lipid composition and packing as well as the structure of the protein on the affinities of apolipoproteins for lipid monolayers have been investigated. The adsorption of 14 C-reductively methylated human apolipoproteins A-I and A-II at saturating subphase concentrations to monolayers prepared with synthetic lipids or lipoprotein surface lipids spread at various initial surface pressures has been studied. The adsorption of apolipoproteins is monitored by following the surface radioactivity using a gas flow counter and Wilhelmy plate, respectively. The physical states of the lipid monolayers are evaluated by measurement of the surface pressure-molecular area isotherms using a Langmuir-Adam surface balance. The probable helical regions in various apolipoproteins have been predicted using a secondary structure analysis computer program. The mean residue hydrophobicity and mean residue hydrophobic moment for the predicted helical segments have been calculated. The surface properties of synthetic peptides which are amphipathic helix analogs have been investigated at the air-water and lipid-water interfaces

    Oral cancer is the 8th most common cancer worldwide. Squamous cell carcinomas constitute 94% of all oral malignancies and are often preceded by leukoplakia. Despite many adjunctive techniques to monitor transformation of leukoplakia to oral squamous cell carcinoma (OSCC), the mortality rate is on the rise. Incidentally, patients diagnosed with oral potentially malignant disorders (OPMDs) and oral cancers manifest with low choles-terol levels. Given a thought, hypolipidemia may be a useful adjunctive tool as it reflects the initial changes within the neo-plastic cells, thus giving a red alert in malignant transformation of leukoplakia at the earlier stage. To evaluate the feasibility of serum lipid profile as an adjunct early marker for malignant transformation of leukoplakia to OSCC. To estimate the serum cholesterol, triglycerides and lipoprotein (HDL, LDL, VLDL) levels in patients with leukoplakia, OSCC and age matched healthy control group. To compare the serum cholesterol, triglycerides and lipoprotein levels between patients of leukoplakia, OSCC and age matched healthy control group. The study group comprised of selected 30 individuals which included 10 each of histopathologically confirmed OSCC, leukoplakia and healthy controls. A written consent was taken from all of them, and a thorough case history was recorded and then venous blood was collected 12 hours post fasting and centrifuged. The serum cholesterol, triglycerides and HDL were estimated by enzymatic and colorimetric methods using commercially available kits--Roche/ Hitachi cobas systems. Chemistry assay QC procured from Bio-Rad was used as control. VLDL and LDL were derived from these values. Results were statistically analyzed using ANOVA and post hoc Tukey Test. Oral squamous cell carcinoma patients demonstrated significantly lower mean serum cholesterol level (151.60 mg/dl) than the control group (183.70 mg/dl). The mean cholesterol level in leukoplakia patients (173.90 mg/dl) was lower than that

    Full Text Available CONTEXT AND OBJECTIVE: Pre-eclampsia is a disorder that occurs only during pregnancy. Postpartum changes relating to lipid metabolism may contribute towards the endothelial lesions observed in preeclampsia. Thus, the aim of the present study was to evaluate the lipid profile among patients who present preeclampsia and correlate these parameters with 24-hour proteinuria. DESIGN AND SETTING: Cross-sectional analytical study including 77 pregnant patients seen at Hospital Dório Silva. METHODS: This study involved 42 women with preeclampsia and 35 healthy pregnant women in the third trimester of pregnancy as controls. Blood samples were obtained from all the patients, and the serum levels of triglycerides, total cholesterol, low-density lipoproteins (LDL, high-density lipoproteins (HDL and very low density lipoproteins (VLDL were determined. Cases and controls were matched for maternal age, gestational week and body mass index. RESULTS: The VLDL and triglyceride values from the women with preeclampsia were significantly higher than those of the healthy women. There was a positive correlation between increased proteinuria and higher VLDL and triglyceride levels in patients with preeclampsia. CONCLUSION: Among the patients with preeclampsia, higher VLDL and triglyceride levels were positively correlated with proteinuria. These observations indicate that the pregnant women who presented elevated lipid levels were more susceptible to cardiovascular disorders and, consequently, pre-eclampsia.

    Ghee, also known as clarified butter, has been utilized for thousands of years in Ayurveda as a therapeutic agent. In ancient India, ghee was the preferred cooking oil. In the last several decades, ghee has been implicated in the increased prevalence of coronary artery disease (CAD) in Asian Indians due to its content of saturated fatty acids and cholesterol and, in heated ghee, cholesterol oxidation products. Our previous research on Sprague-Dawley outbred rats, which serve as a model for the general population, showed no effect of 5 and 10% ghee-supplemented diets on serum cholesterol and triglycerides. However, in Fischer inbred rats, which serve as a model for genetic predisposition to diseases, results of our previous research showed an increase in serum total cholesterol and triglyceride levels when fed a 10% ghee-supplemented diet. In the present study, we investigated the effect of 10% dietary ghee on microsomal lipid peroxidation, as well as serum lipid levels in Fischer inbred rats to assess the effect of ghee on free radical mediated processes that are implicated in many chronic diseases including cardiovascular disease. Results showed that 10% dietary ghee fed for 4 weeks did not have any significant effect on levels of serum total cholesterol, but did increase triglyceride levels in Fischer inbred rats. Ghee at a level of 10% in the diet did not increase liver microsomal lipid peroxidation or liver microsomal lipid peroxide levels. Animal studies have demonstrated many beneficial effects of ghee, including dose-dependent decreases in serum total cholesterol, low density lipoprotein (LDL), very low density lipoprotein (VLDL), and triglycerides; decreased liver total cholesterol, triglycerides, and cholesterol esters; and a lower level of nonenzymatic-induced lipid peroxidation in liver homogenate. Similar results were seen with heated (oxidized) ghee which contains cholesterol oxidation products. A preliminary clinical study showed that high doses of

    BACKGROUND: Population-based studies investigating the sex-specific association between thyrotropin (TSH) levels and serum lipid concentrations are scarce. We examined the association between TSH and total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL......) cholesterol, and triglycerides in men and women from the general population. Furthermore, the association with TSH outside and within the reference range and lipid levels was studied. METHODS: Individual data of 13,571 men and women without lipid medication of four population-based studies conducted...... in Western European adults were pooled for cross-sectional analyses. The association between TSH levels and lipid concentrations were analyzed by calculating sex-specific multivariable median regression models. RESULTS: In the pooled population, serum TSH levels were significantly positively associated...

    Observed adverse effects of antiretroviral therapy (ART) on the lipid profile could be of significance in pregnancy. This systematic review aims to summarize studies that investigated the association between HIV, ART and serum lipids during pregnancy and adverse pregnancy outcomes. A systematic search was conducted in five electronic databases to obtain articles that measured serum lipid concentrations or the incidence of dyslipidaemia in HIV-infected pregnant women. Included articles were assessed for quality according to the Cochrane Risk of Bias Tool. The extracted data was analysed through descriptive analysis. Of the 1264 articles screened, 17 articles were included in this review; eleven reported the incidence of dyslipidaemia, and twelve on maternal serum lipid concentrations under the influence of HIV-infection and ART. No articles reported pregnancy outcomes in relation to serum lipids. Articles were of acceptable quality, but heterogenic in methods and study design. Lipid levels in HIV-infected women increased 1.5-3 fold over the trimesters of pregnancy, and remained within the physiological reference range. The percentage of women with dyslipidaemia was variable between the studies [0-88.9%] and highest in the groups on first generation protease inhibitors and for women on ART at conception. This systematic review observed physiologic concentrations of serum lipids for HIV-infected women receiving ART during pregnancy. Serum lipids were increased in users of first generation protease inhibitors and for those on treatment at conception. There was no information available about pregnancy outcomes. Future studies are needed which include HIV-uninfected control groups, control for potential confounders, and overcome limitations associated with included studies.

    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

    Full Text Available Background: Researchers have reported association of plasma/serum lipids and lipoproteins with different cancers. Increase levels of circulating lipids and lipoproteins have been associated with breast cancer risk. Aim: The aim of this study is to compare serum lipid profiles: total-cholesterol (T-CHOL, triglyceride (TG, high density lipoprotein-cholesterol (HDL-C, low density lipoprotein-cholesterol (LDL-C and very low density lipoprotein-cholesterol (VLDL-C between breast cancer patients and normal participants. Materials and Methods: A total of 403 women in this study were divided into two groups in the period during May 2006-April 2007. Blood samples were collected from 249 patients with early stage breast cancer and 154 normal controls for serum lipid profiles (T-CHOL, TG, HDL-C, LDL-C and VLDL-C analysis using Hitachi 717 Autoanalyzer (Roche Diagnostic GmbH, Germany. TG, LDL-C and VLDL-C levels in breast cancer group were significantly increased as compared with normal controls group (P < 0.001, whereas HDL-C and T-CHOL levels were not. Results: The results of this study suggest that increased serum lipid profiles may associate with breast cancer risk in Thai women. Further studies to group important factors including, cancer stages, types of cancer, parity, and menopausal status that may affect to lipid profiles in breast cancer patients along with an investigation of new lipid profiles to clarify most lipid factors that may involve in breast cancer development are needed.

    Full Text Available Background. Nowadays, herbs they are considered to be the main source of effective drugs for lowering serum lipids and lipid peroxidation. The present experimental animal study aimed to assess the impact of Ferulago angulata on serum lipid profiles, and on levels of lipid peroxidation. Methods. Fifty male Wistar rats, weighing 250–300 g, were randomly divided into five equal groups (ten rats in each. The rat groups received different diets as follows: Group I: fat-rich diet; Group II: fat-rich diet plus hydroalcoholic extracts of Ferulago angulata at a dose of 400 mg/kg; Group III: fat-rich diet plus hydroalcoholic extracts of Ferulago angulata at a dose of 600 mg/kg; Group IV: fat-rich diet plus atorvastatin; Group V: common stock diet. The levels of serum glucose and lipids and the atherogenic index were measured. In addition, malondialdehyde (MDA, thiol oxidation, carbonyl concentrations, C-reactive proteins, and antioxidant capacity were evaluated in each group of rats. Results. Interestingly, by adding a hydroalcoholic extract of Ferulago angulata to the high-fat diet, the levels of total cholesterol and low-density lipoproteins (LDL in the high-fat diet rats were both significantly reduced. This result was considerably greater compared to when atorvastatin was added as an antilipid drug. The beneficial effects of the Ferulago angulata extract on lowering the level of triglycerides was observed only when a high dosage of this plant extraction was added to a high fat diet. Furthermore, the level of malondialdehyde, was significantly affected by the use of the plant extract in a high-fat diet, compared with a normal regimen or high-fat diet alone. Conclusion. Administration of a hydroalcoholic extract of Ferulago angulata can reduce serum levels of total cholesterol, triglycerides, and LDL. It can also inhibit lipid peroxidation.

    High cholesterol has been advanced as the most important factor in the development of coronary artery disease. Most panels have recommended population-wide dietary restrictions, yet a body of evolving data yields evidence of the hazards of low cholesterol, including links to aggression and hostility. The aim of this study was to compare the serum lipid profile and serum apolipoproteins A1 and B of men with a violent criminal record and men with no criminal history. Fasting blood samples were collected from 30 men with a known history of violent crime and 30 men with no criminal record. Serum lipid profile and serum apolipoproteins A1 and B were measured in each sample, and compared between the two groups. The group with the violent criminal record showed significantly lower total cholesterol, lower LDL cholesterol, higher apolipoprotein A1 and lower apolipoprotein B compared with the control group. Lower total cholesterol, lower LDL cholesterol, higher apolipoprotein A1 and lower apolipoprotein B could predispose to violence. Future research might explore the possibility that diets offered in prison could affect relevant pathways in lipid metabolism. Copyright (c) 2006 John Wiley & Sons, Ltd.

    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.

    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.

    The aim of this study is to evaluate the carotid intima media thickness and serum lipids in pediatric patients with epilepsy treated with oxcarbazepine. The study included 21 pediatric epileptic and 22 healthy children. Intima media thickness and fasting lipid profile were assessed. Although the median value of total cholesterol was in normal limits in the oxcarbazepine group, it was significantly higher when compared with the control group. We did not observe any differences regarding triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and carotid intima media thickness. We suggest that oxcarbazepine treatment in children has a minor effect on serum lipids and it does not seem to have an atherogenic effect. Copyright © 2011 The Japanese Society of Child Neurology.

    Full Text Available BACKGROUND: Trans fatty acids are known as the most harmful type of dietary fats, so this study was done to compare the effects of hydrogenated, liquid and ghee oils on serum lipids profile of healthy adults.    METHODS: This study was a randomized clinical trial conducted on 129 healthy participants aged from 20 to 60 years old who were beneficiaries of Imam-e-Zaman charitable organization. Subjects were randomly divided into 3 groups and each group was treated with a diet containing cooking and frying liquid, ghee, or hydrogenated for 40 days. Fasting serum lipids, including total cholesterol (TC, triglyceride (TG, LDL-cholesterol (LDL-C, HDL-cholesterol (HDL-C, apoprotein A (Apo A, and apoprotein B (Apo B were measured before and after the study.    RESULTS: TC, TG and Apo B had a significant reduction in the liquid oil group compared to the hydrogenated oil group. In the ghee group TG declined and Apo A increased significantly (p < 0.01. Liquid oil group had a significant reduction in HDL-C, compared to the ghee oil group (P < 0.05.     CONCLUSION: It was concluded that consuming liquid oil along with frying oil caused to reduce all serum lipid levels. However, ghee oil only reduced TG and increased HDL-C levels.      Keywords: Serum lipids, Apoproteins, Liquid oil, Hydrogenated oil, Ghee, Clinical trial

    Disturbances in lipid metabolism during copper deficiency in rats are well recognized. Copper deficiency is associated with the spontaneous retention of hepatic iron. Previous studies have reported that hypercholesterolemia and hypertriglyceridemia are associated with elevated hepatic iron concentrations in copper deficient rats. There was a direct relationship between the magnitude of blood lipids and the concentration of hepatic iron. Based on these data, it has been hypothesized that iron was responsible for the development of lipemia of copper deficiency. In this study was determined the effect of increasing doses of Cu(10, 20 and 50 ppm) in the diet, on the serum total lipids, total cholesterol, triglycerides (triacylglicerols), phospholipids, non-esterified fatty acids (NEFA) and liver iron and zinc concentrations in normal rats. The results were compared with normal rats that received a balanced diet containing 0.6 and 6 ppm of Cu, respectively. The results show that Cu-supplement diminished the cholesterol and triglyceride serum levels, increased the level of phospholipids, NEFA and concomitantly decreased the hepatic concentrations of Fe and Zn. There was a statistically significant (p Cu (r = -0.612), liver Fe and liver Zn (r = 0.837), liver Cu and liver Zn (r = -0.612), and serum triglycerides and liver Zn (r = 0.967). The mechanism(s) by which Fe and Zn determine these changes is not known; none of the enzymes that act in cholesterol and triglyceride metabolism and biosynthesis require Fe and/or Zn. The increase of NEFA is due to changes in the process of lipolysis and re-esterification of the fatty acids in blood. However, additional studies are needed for the precise mechanisms of this interrelationships to be clarified.

    The serum levels of ascorbic acid (ASA), total cholesterol, HDL cholesterol and triglyceride were estimated in 82 healthy persons who consisted of 41 men aged 18 to 69 and 41 women aged 32 to 69. None of fasting lipid profils correlated with the serum level of ASA in total subjects. In young men aged 18 to 23, however, there was significant negative correlation between ASA and total cholesterol. These findings suggest that ASA may be one of effective drug to decrease the level of cholesterol.

    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.

    Ramadan, the holy month for the Islamic world, is a period every year when food and fluid intake is restricted to the pre-sunrise and post-sunset hours. The aim of this study was to evaluate the effect of Ramadan fasting on the serum concentration of heat shock protein 70 (HSP70) and serum lipid profile in healthy men. A total of 32 male volunteers with a mean age of 28.5 (range 23-37) years were selected for the study. Blood samples were obtained one day prior to Ramadan and on the 3rd and 25th days of fasting. Serum HSP70, triglyceride (TG), cholesterol (Chol), low-density lipoprotein (LDL) and high-density lipoprotein (HDL), LDL/HDL and Chol/HDL ratios were investigated. It was observed that the mean concentrations of serum HSP70 and HDL on the 25th day of Ramadan were significantly higher than those recorded one day before Ramadan and on the 3rd day of Ramadan, and the levels on the 3rd day of Ramadan was significantly higher than those recorded one day before Ramadan. Mean concentrations of serum TG, Chol, LDL, and LDL/HDL and Chol/HDL ratios on the 25th day of Ramadan were significantly lower than those recorded one day before Ramadan and on the 3rd day of Ramadan, and the levels found on the 3rd day of Ramadan were also significantly lower than those recorded one day before Ramadan. Ramadan fasting increases serum HSP70 and improves serum lipid profile.

    The effects of exposure to ozone (O/sub 3/) on concentrations of serum lipids and lipoproteins were investigated. Male and female guinea pigs were exposed to O/sub 3/ at 1 ppm for two weeks. Serum concentrations of cholesterol, triglycerides, low density (LDL) and very low density (VLDL) lipoproteins were elevated after O/sub 3/ exposure, particularly in males. During O/sub 3/ exposure the food intake per day decreased (for a constant body weight), suggesting that metabolic rate and possibly basal metabolic rate was lower. Lung wet weights increased during O/sub 3/ exposure by 87% for males and 45% for females. When individual lung weight/body weight ratios were correlated with cholesterol and LDL values from the same animal, a high correlation is found for males (r . 0.81, P less than 0.05), suggesting that there may be a relationship between lipoprotein elevations and lung damage for males. Because elevated concentrations of lipids and lipoproteins in humans increase the risk of coronary heart disease (CHD), the lipoprotein results suggest that an epidemiological study of the incidence of CHD with metropolitan O/sub 3/ levels may be warranted.

    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.

    Full Text Available We aimed to explore the associations between different lipid profiles and semen quality in a large-scale general male population. Sperm concentration, total sperm motility, progressive motility, and normal sperm morphology of total 7601 participants were recorded. The association of these semen parameters with the triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotein, and very low-density lipoprotein of serum lipid profiles was analyzed. Sperm concentration was statistically positively correlated with triglyceride and very low-density lipoprotein (adjusted P = 0.001 and P = 0.005, respectively. Total sperm motility and progressive motility were statistically increased with increasing low-density lipoprotein and cholesterol levels (both adjusted P = 0.008 and P < 0.001, respectively. The similar J-shaped associations (high-low-low-high were noted between individual lipid profile and normal sperm morphology, especially low-density lipoprotein and cholesterol with statistical significance (adjusted P = 0.017 and P = 0.021, respectively. The prevalence of abnormal total sperm motility and progressive motility was decreased in participants with high levels of cholesterol (P = 0.008 and P = 0.019, respectively, and the reverse J-shaped associations (low-high-high-low were noted between high-density lipoprotein, triglyceride, very low-density lipoprotein, and the prevalence of abnormal normal sperm morphology (P = 0.010, P = 0.037, and P = 0.025, respectively. A high cholesterol level was associated with better sperm motility. Similar J-shaped associations were noted between all lipid profiles and normal sperm morphology; meanwhile, the reverse J-shaped trends were identified between them and abnormal normal sperm morphology prevalence.

    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.

    The dynamics of changes in serum lipids (free fatty acids, free glycerol, triglycerides, total cholesterol, and phospholipids) were studied in male Wistar rats irradiated in an open experimental field with a daily dose of 15.48 mC.kg -1 (60 R) up to a total exposure of 774.0 mC.kg -1 (3,000 R). The resulting changes occurred in several periods. The initial period of 0 to 7 days included a drop in the triglyceride level and a rise in free glycerol, total cholesterol, and phospholipids in both the control and irradiated rats. The period of 14 to 25 days marked the appearance of serum hyperlipaemia. Between 25 and 50 days, the levels of the different fractions oscillated and existing changes became more pronounced. The general level of serum lipids during continuous gamma irradiation exceeded that found in the controls. Changes in the control animals from the experimental field reflected the effect of a changed environment. The modifying factor affecting both the irradiated and control rats was night fasting prior to sacrificing the animals and, probably, also the presence of an infradian rhythm in some serum lipid fractions.

    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)

    Full Text Available Alzheimer’s disease (AD is a multifactorial disease but its aetiology and pathophisiology are still not fully understood. Epidemiologic studies examining the association between lipids and dementia have reported conflicting results. High total cholesterol has been associated with both an increased, and decreased, risk of AD and/or vascular dementia (VAD, whereas other studies found no association. The aim of this study was to investigate the serum lipids concentration in patients with probable AD, as well as possible correlation between serum lipids concentrations and cognitive impairment.Our cross-sectional study included 30 patients with probable AD and 30 age and sex matched control subjects. The probable AD was clinically diagnosed by NINCDS-ADRDA criteria. Serum total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C and triglyceride (TG levels were determined at the initial assessment using standard enzymatic colorimetric techniques. Low-den- sity lipoprotein cholesterol (LDL-C and very low density lipoprotein cholesterol (VLDL-C levels were calculated. Subjects with probable AD had significantly lower serum TG (p<0,01, TC (p<0,05, LDL-C (p<0,05 and VLDL-C (p<0,01 compared to the control group. We did not observe signifi-cant difference in HDL-C level between patients with probable AD and control subjects. Negative, although not significant correlation between TG, TC and VLDL-C and MMSE in patients with AD was observed. In the control group of subjects there was a negative correlation between TC and MMSE but it was not statistically significant (r = -0,28. Further studies are required to explore the possibility for serum lipids to serve as diagnostic and therapeutic markers of AD.

    Severe hypertriglyceridemia is a known, but uncommon complication of diabetic ketoacidosis. We discuss the case of a 23-year-old, previously healthy, woman who initially presented to the emergency department with abdominal pain. Grossly lipemic serum due to extremely high triglyceride (38.6 mmol/L) and cholesterol (23.2 mmol/L) levels were observed with a high blood glucose (23 mmol/L) and a low pH of 7.06 on a venous blood gas. She was treated successfully with fluids and insulin and had no sequale of pancreatitis or cerebral edema. Her triglycerides and cholesterol was normalized in three days and she was discharged home on insulin therapy after five days. Further history revealed a recent change in diet with no meat, fish or poultry consumption in the last 12 months and concomitantly an increase in carbohydrate intake which might have contributed to her extremely high serum lipid levels. This case demonstrates that clinicians should be mindful of the different presentations of diabetic ketoacidosis. Key words: diabetic ketoacidosis, hypertriglyceridemia, hyperlipidemia, vegan diet, carbohydrate diet. Correspondence: Hrafnkell Stefansson, hrafnkell.stefans@gmail.com.

    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.

    To investigate whether low-grade inflammation-related factors such as serum low-density (LDL-C) and high-density lipoprotein cholesterol (HDL-C) modify the association between periodontal infection and C-reactive protein. This study was based on a subpopulation of the Health 2000 Survey, which consisted of dentate, non-diabetic, non-rheumatic subjects who were 30-49 years old (n = 2710). The extent of periodontal infection was measured by means of the number of teeth with periodontal pocket ≥4 mm and teeth with periodontal pocket ≥6 mm and systemic inflammation using high sensitive C-reactive protein. The extent of periodontal infection was associated with elevated levels of C-reactive protein among those subjects whose HDL-C value was below the median value of 1.3 mmol/l or LDL-C above the median value of 3.4 mmol/l. Among those with HDL-C ≥ 1.3 mmol/l or LDL-C ≤ 3.4 mmol/l, the association between periodontal infection and serum concentrations of C-reactive protein was practically non-existent. This study suggests that the relation of periodontal infection to the systemic inflammatory condition is more complicated than previously presumed. The findings of this study suggest that the possible systemic effect of periodontal infection is dependent on serum lipid composition. © 2012 John Wiley & Sons A/S.

    The serum resistin level is associated with the incidence of ischemic heart disease in the general population. We analyzed the associations between serum resistin and fat intake, serum lipid concentrations and adiposity in the general population. A cross-sectional study of 6,637 randomly recruited adults was conducted. The resistin levels were measured in thawed aliquots of serum using an enzyme immunoanalysis technique. The resistin level exhibited a positive nonparametric correlation with saturated fat intake(p correlation with adherence to the Mediterranean diet(p HDL cholesterol(p body mass index(p HDL cholesterol level(OR=0.84 CI95%= 0.76-0.93), a high non-HDL cholesterol level(OR=0.84 CI95%=0.72-0.99), a high LDL cholesterol level(OR=0.82 CI95%=0.70-0.97) and a waist/height ratio of ≥0.55(OR=0.76 CI95%=0.67-0.85). The multivariate models corroborated the positive associations between the resistin level and saturated fat intake(p adiposity.

    Major depressive disorder (MDD) is associated with suicide. Although several studies have reported its association with low serum lipid, few studies have investigated relationships between current suicidality and lipid profiles, comparing with other blood measures in MDD patients. The study population consisted of 555 subjects with MDD who were ≥ 18 years old, evaluated by the Mini International Neuropsychiatric Interview (MINI) with the suicidality module. At the evaluation visit, we measured serum lipid profiles including total cholesterol, triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very low-density lipoprotein (VLDL), and blood measures such as fasting glucose, total protein, albumin, blood urea nitrogen, creatinine, thyroid hormones, red and white blood cells, platelet count, hemoglobin, and hematocrit. Recent attempters who had attempted suicide within the past month showed significantly lower TG and higher HDL levels than lifetime and never attempters, using Tukey's post-hoc analysis. Recent attempters exhibited lower TG and higher HDL than those with recent suicide ideation and wish to self-harm and those without previous attempt. Linear regression analysis revealed that TG was negatively associated with current suicidality scores (β = -0.187, p = 0.039), whereas VLDL was positively associated with the recent suicide status (β = 0.198, p = 0.032) after controlling for age and sex. There were no significant differences between the groups in terms of other serum lipid profiles and blood measures. Low serum TG, high HDL and VLDL levels are associated with recent suicide attempt or recent suicide status in patients with MDD. Copyright © 2014 Elsevier Inc. All rights reserved.

    Prevention of cardiovascular disease by modifying its major risk factors, including serum cholesterol levels, is an important strategy. Hibiscus sabdariffa L. has been promoted for reducing cholesterol levels, but its reported impact on cholesterol levels has been inconsistent. The study aimed to assess systematically the evidence and quality of current research on the effect of Hibiscus sabdariffa L. on blood lipids and its adverse effects. Electronic databases were searched up to June 2013 for relevant randomised controlled trials (RCTs). Journals and conference proceedings were also searched. The quality of the selected trials was assessed using the Cochrane Risk of Bias Assessment Tool. The efficacy results of similar studies were pooled if they used the same comparator. Outcomes examined were levels of total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and triglycerides. Six studies involving 474 subjects met our inclusion criteria. These studies varied in terms of the types of interventions, comparators used, and duration of trials. Overall, Hibiscus sabdariffa L. did not produce any significant effect on any of the outcomes examined, when compared with placebo, black tea or diet. With short-term use it is well tolerated. The available evidence from RCTs does not support the efficacy of Hibiscus sabdariffa L. in lowering serum lipids. Further rigorously designed trials with larger sample sizes are warranted to confirm the effects of HS on serum lipids. © 2013 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available The research was performed on 40 chicken broilers of Cobb provenience to investigate the effect of dietary black cumin seed oil on some blood biochemical parameters in chicken broilers. 40 chicken broilers who were included in the 42 days lasting experiment were divided into two groups, each one of 20 individuals. Group K was the control – with no added oil in feed mixture and the second group P was the experimental one – chickens were fed with 0,025 g of p.o. administered black cumin seed oil. Feed and water supplies were ad libitum. Microclimate conditions (light, temperature and airflow were maintained according to the technological procedure. Blood samples were taken from the wing vein of all animals from both groups at age of 25, 32 and 39 days. The following blood serum biochemical parameters were determined: total lipids, triglycerides, total cholesterol, albumen and calcium. Dietary black cumin seed oil significantly (P<0.05 affected serum lipid components, particularly total lipids, but not albumen and calcium in chicken broilers. Possible reason for these findings could be dietary fat component as well as fatty-acid composition of added black cumin seed oil. Key words: black cumin seed oil, chicken broilers, blood serum biochemical parameters, fatty acid composition of oil

    Shiitake (Lentinula edodes) extract, eritadenine, has been shown to reduce cholesterol levels, and its hypocholesterolemic actions are involved in the metabolism of methionine. However, the mechanisms by which eritadenine affects cholesterol metabolism in animals fed a high-fat diet containing different sources of lipids have not yet been elucidated in detail. This study was conducted to investigate the effects of shiitake supplementation on serum lipid concentrations in rats fed a diet including a high amount of a plant oil (HO [high oil] and HOS [high oil with shiitake] groups), animal fat (HF [high fat] and HFS [high fat with shiitake] groups), or MCT- (medium-chain triglyceride-) rich plant oil (HM [high MCT] and HMS [high MCT with shiitake] groups). Rats in the HOS, HFS, and HMS groups were fed shiitake. When rats were fed a diet containing shiitake, serum triglyceride, cholesterol levels, and LCAT (lecithin-cholesterol acyltransferase) activities were lower in rats given MCT-rich plant oil than in those that consumed lard. The lipid type in the diet with shiitake also affected serum cholesterol levels and LCAT activities. The diet containing MCT-rich plant oil showed the greatest rates of decrease in all serum lipid profiles and LCAT activities. These results suggest that shiitake and MCT-rich plant oil work together to reduce lipid profiles and LCAT activity in serum.

    Cationic liposome (CL)-DNA complexes are promising gene delivery vectors with potential application in gene therapy. A key challenge in creating CL-DNA complexes for application is that their transfection efficiency (TE) is adversely affected by serum. In particular, little is known about the effects of a high serum content on TE, even though this may provide design guidelines for application in vivo. We prepared CL-DNA complexes in which we varied the neutral lipid [1,2-dioleoyl-sn-glycerophosphatidylcholine, glycerol-monooleate (GMO), cholesterol], the headgroup charge and chemical structure of the cationic lipid, and the ratio of neutral to cationic lipid; we then measured the TE of these complexes as a function of serum content and assessed their cytotoxicity. We tested selected formulations in two human cancer cell lines (M21/melanoma and PC-3/prostate cancer). In the absence of serum, all CL-DNA complexes of custom-synthesized multivalent lipids show high TE. Certain combinations of multivalent lipids and neutral lipids, such as MVL5(5+)/GMO-DNA complexes or complexes based on the dendritic-headgroup lipid TMVLG3(8+) exhibited high TE both in the absence and presence of serum. Although their TE still dropped to a small extent in the presence of serum, it reached or surpassed that of benchmark commercial transfection reagents, particularly at a high serum content. Two-component vectors (one multivalent cationic lipid and one neutral lipid) can rival or surpass benchmark reagents at low and high serum contents (up to 50%, v/v). We propose guidelines for optimizing the serum resistance of CL-DNA complexes based on a given cationic lipid. Copyright © 2014 John Wiley & Sons, Ltd.

    Objective: Females with different menopausal status are compared for serum lipids to explore the role of menopausal status in developing gallstones. Methodology: This study was conducted at Institute of Biochemistry, University of Sindh Jamshoro, Pakistan. A total number of 135 female gallstone patients admitted at Liaquat University Hospital, Wali Bhai Rajputana Hospital, Hyderabad and other hospitals of Hyderabad, Pakistan and 170 age and gender matched control subjects were selected for the study. The serum samples of patients of different menopausal status and control group were analyzed for the lipid contents. Gallstones recovered from the patients were also analyzed for the composition by FTIR. Results: Serum total cholesterol (TC) and serum high density lipoprotein cholesterol (HDL-C) were significantly varied among all age groups while serum triglycerides (TG), serum very low density lipoprotein cholesterol (VLDL-C) and serum total lipids (TL) were found to be significantly differed among four different types of gallstone formers. Consumers of non-branded oil and non-branded ghee were found with significant lipid alterations in comparison to control group. Major lipid alterations were found in female gallstone patients with pre and peri-menopause. Conclusion: Raised serum TC, serum TG and decreased serum HDL-C in addition to pre- and peri-menopausal status may be considered as biomarkers for female gallstone patients.

    The objectives were to quantify gastrointestinal tolerance, total tract nutrient digestibility, and serum lipid profiles of dogs as affected by α-cyclodextrin (ACD) supplementation and to validate the accuracy of fat analyses techniques using novel ACD-fat complexes. The ACD was hydrolyzed and free sugars and hydrolyzed monosaccharides were quantified using high performance liquid chromatography. Known amount of fats were complexed with ACD, and fat content of complexes were determined using the ether extraction and acid-hydrolyzed fat methods. Nine mixed-breed hounds were used in a crossover design with 3 periods of 10 d each, including 6 d for diet adaptation and 4 d for fecal collection. Dogs were fed twice daily a diet with poultry byproduct meal and brewer's rice as the main ingredients, and chromic oxide (0.2%) was included as a digestion marker. Dogs were supplemented with either 0, 3, or 6 g of ACD diluted in 15 mL of water twice per day for a total of 0, 6, and 12 g ACD per day. The ACD had a very low free sugar concentration and, once hydrolyzed, released only glucose, as expected. Average daily food intake, fecal output (DM basis), and fecal scores were not significantly different among treatments. Body weight and condition score and serum triglycerides and cholesterol concentrations remained unaltered throughout the duration of the experiment. Dry matter, OM, and fat digestibility coefficients were lower (P < 0.05) for both treatment groups compared to the control. The acid-hydrolyzed fat method was valid to measure fat that was bound to ACD. Intake of ACD lowered fat digestibility somewhat but not to the extent previously reported, without affecting serum lipid concentrations or outcomes related to tolerance. Therefore, ACD supplementation resulted in a small decrease in fat digestibility, but ACD supplementation might have potential in modifying serum lipid profiles.

    The objective here was to summarize the evidence for, and quantify the link between, serum markers of lipid metabolism and risk of obesity-related cancers. Pub Med and Embase were searched using predefined inclusion criteria to conduct meta-analyses on the association between serum levels of TG, TC, HDL, ApoA-I, and risk of 11 obesity-related cancers. Pooled relative risks (RRs) and 95% confidence intervals were estimated using random-effects analyses. 28 studies were included. Associations between abnormal lipid components and risk of obesity-related cancers when using clinical cut points ( TC ≥ 6.50; TG ≥ 1.71; HDL ≤ 1.03; ApoA-I ≤ 1.05 mmol/L) were apparent in all models. RRs were 1.18 (95% CI: 1.08-1.29) for TC, 1.20 (1.07-1.35) for TG, 1.15 (1.01-1.32) for HDL, and 1.42 (1.17-1.74) for ApoA-I. High levels of TC and TG, as well as low levels of HDL and ApoA-I, were consistently associated with increased risk of obesity-related cancers. The modest RRs suggest serum lipids to be associated with the risk of cancer, but indicate it is likely that other markers of the metabolism and/or lifestyle factors may also be involved. Future intervention studies involving lifestyle modification would provide insight into the potential biological role of lipid metabolism in tumorigenesis.

    There have been inconsistent reports on the relationships between lipids and suicidality, and studies conducted in older adults are rare. This study examined associations between serum lipid levels and suicidal ideation in an older population. This study used data obtained from a representative Korean sample of 4265 people age 65 years or older who completed a self-administered questionnaire about suicidal ideation over the last year. The fasting serum concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides were measured and categorized into lower, intermediate (reference), and upper quartiles. A complex sample logistic regression stratified by gender was performed to determine the associations between serum lipid levels and suicidal ideation after controlling for covariates including age, education, marital status, current smoking, alcohol drinking, body mass index, hypertension, diabetes, diagnosed depression, antidepressant use, and lipid-lowering therapies. In this study, the prevalence of suicidal ideation in an older Korean population was 22.9% (SE=0.9%). The prevalence was significantly higher in women than in men, 27.7% (1.2%) vs. 15.9% (1.1%) respectively. After adjusting for covariates, lower triglyceride levels were significantly associated with a decreased risk of suicidal ideation (OR=0.65; 95% CI=0.43-0.99) among men but no significant associations were observed among women. Additionally, there were no significant associations between any other measure of cholesterol levels and suicidal ideation in either men or women. Cross-sectional design cannot infer temporality or the effects of changes in variables. These results support the association between lower triglyceride levels and a reduced risk of suicidal ideation among Korean men over 65.

    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.

    I Jen Chang

    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

    Jin-Chun Lu

    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.

    Serum lipid levels were measured in 66 healthy sloth bears (Melursus ursinus ursinus) living under semicaptive conditions with access to natural food resources in the Bannerghatta Biological Park (Karnataka, India), a portion of their native habitat range in the Indian peninsula. Total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein cholesterol levels were analyzed. The effects of age, body weight, and season on these lipid parameters were statistically evaluated. There were no correlations between age and any of the serum lipid parameters analyzed. Positive correlations of body weight to both triglyceride and HDL cholesterol levels in these bears were identified. In addition, seasonal trends in physiological serum lipid values, potentially due to variations in the sloth bear diet, were identified. Serum triglyceride levels were higher during postmonsoon season and cholesterol levels were higher during winter compared to other seasons. Serum lipid values obtained from sloth bears in this study were also compared to previously published data on other members of the family Ursidae. This is the first report of serum lipid values as a reference for sloth bears. These values can be used as sensitive predictors of overall health and nutritional status to aid in the captive management and feeding of these bears.

    The present study was undertaken to explore the possible role of serum lipid profile in gallstone formation. For this serum lipid profile such as total, free and bound cholesterol, LDL cholesterol, HDL cholesterol, triacylglycerols and total lipids were determined in 109 gallstone patients and 100 controls (matched for age, sex and with negative personal or family history of gallstones) treated at Liaquat University Hospital, Jamshoro, Pakistan. Comparison for serum lipid profile between different groups of gallstone patients and controls revealed no significant variation except for the triacylglycerols and total lipids, which were differed significantly between females of up to 45 and above 45 years age. Comparison for serum lipid profile between pure cholesterol and mixed composition gallstone formers showed no significant difference (p>0.05) between the two groups. The serum lipid profile significantly varied between gallstone patients and controls except bound cholesterol level. Comparison of total cholesterol, free cholesterol, LDL cholesterol, HDL cholesterol, triacylglycerols and total lipids between gallstone patients and controls revealed that there was a significant difference between gallstone patients and controls for (a) females with or without gallstones, (b) females of up to 45 years age and (c) females having more than 3 children. HDL cholesterol is significantly decreased in all the groups of gallstone patients as compared to controls, whereas, bound cholesterol remained non significant in all the groups of gallstone patients when compared with controls. In conclusion, elevated serum total cholesterol, free cholesterol, LDL cholesterol, triacylglycerols and decreased levels of HDL cholesterol seem to play major contributing role in the pathogenesis of gallstones in females of up to 45 years age with more than three children.

    Full Text Available Passive cigarette smoke contains five times more carbon monoxide and six times more nicotine compared to the main smoke because cigarette filter has a protective role for smokers. Cigarette smoke contains a range of oxidants and free radicals that can directly or indirectly induce oxidative stress in the body. Adding some aromatic ingredients to cigarette may play an important role in increasing damage and free radicals. The aim of this study was to evaluate the effects of passive inhalation of cigarette smoke on serum lipid profile in rats. For this purpose, 16 male Wistar rats were divided randomly into two groups of eight rats, control and treatment. There was no intervention in the control group, but treatment group was exposed to a cigarette passive smoke on a daily basis for a month. After a month, the rat tail vein blood samples were taken and after separation of the sera, serum lipid profiles, including triglycerides, total cholesterol, LDL and HDL was measured and the results were statistically analyzed using t-test. There was a significant (p

    Full Text Available Dyslipidemia was present in most of the patients with coronary heart disease. Epidemiological evidence suggests that anthocyanin has some effects on the serum lipid. However, these results are controversial. This study aimed at collecting current clinical evidence and evaluating the effects of anthocyanin supplementation on total cholesterol (TC, triglyceride (TG, low-density lipoprotein cholesterol (LDL-C, and high-density lipoprotein cholesterol (HDL-C in dialysis patients.The search included PubMed, Web of Science, MEDLINE, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database (up to July 2015 to identify randomized controlled trials (RCTs on the association between anthocyanin and serum lipids. RevMan (version 5.2 was used for Meta-analysis. Meta-regression analysis, sensitivity analysis and Egger's weighted regression tests were performed by using STATA software (version 12.0; StatCorp, College Station, TX, USA.Six studies (seven arms involving 586 subjects were included in this meta-analysis. The results showed that anthocyanin supplementation has significant effects on TC [MD = -24.06, 95% CI(-45.58 to -2.64 mg/dL, I2 = 93%], TG [MD = -26.14, 95%CI(-40.20 to -3.08 mg/dL, I2 = 66%1], LDL-C [MD = -22.10, 95% CI (-34.36 to -9.85 mg/dL, I2 = 61%], and HDL-C(MD = 5.58, 95% CI (1.02 to 10.14 mg/dL;I2 = 90%.Anthocyanin supplementation significantly reduces serum TC, TG, and LDL-C levels in patients with dyslipidemia, and increases HDL-C. Further rigorously designed RCTs with larger sample sizes are needed to confirm the effectiveness of anthocyanin supplementation for dyslipidemia, especially hypo high density lipoprotein cholesterolemia.

    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.

    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.

    Ghrelin has been recognized for its involvement in food intake, control of energy homeostasis, and lipid metabolism. However, the roles of genetic variations in the ghrelin precursor gene (GHRL) on body compositions and serum lipids are not clear in humans. Our study investigated five single-nucleotide polymorphisms (SNPs) within GHRL to determine their relationship with body fat percentage (BF), trunk fat percentage (TF), lower body (legs) fat percentage (LF), and serum lipids in 1,464 subjects, which were recruited from the genetically homogeneous population of Newfoundland and Labrador (NL), Canada. Serum glucose, insulin, total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, and triglycerides were determined. Five SNPs are rs35684 (A/G: a transition substitution in exon 1), rs4684677 (A/T: a missense mutation), rs2075356 (C/T: intron), rs26802 (G/T: intron), and rs26311 (A/G: near the 3' untranslated region) of GHRL were genotyped using TaqMan validated or functionally tested SNP genotyping assays. Our study found no significant evidence of an allele or genotype association between any of the variant sites and body compositions or serum lipids. Furthermore, haplotype frequencies were not found to be significantly different between lean and obese subjects. In summary, the results of our study do not support a significant role for genetic variations in GHRL in the differences of body fat and serum lipid profiles in the NL population.

    Patterns of serum biochemical parameters vary among horse breeds. The objective of the present study was to compare serum lipoproteins of Iranian Caspian ponies with those of other horses (Arabs and Thoroughbreds) in the Iranian region. Serum lipoprotein values were determined by agar-agarose gel electrophoresis and measured by scan densitometry. Moreover, serum triglyceride and cholesterol concentrations were determined and the results were analysed by one-way analysis of variance. Serum triglyceride and cholesterol values were 1.13 +/- 0.23 and 2.38 +/- 0.18 mmol/l in Caspian ponies, 1.96 +/- 0.49 and 1.92 +/- 0.25 mmol/l in Arab horses and 1.38 +/- 0.26 and 2.17 +/- 0.53 mmol/l in Thoroughbred horses. The relative percentages of alpha- (72.63 +/- 17.76%) and beta-lipoproteins (29.10 +/- 5.49%) in serum electrophoretic tracings from Caspian ponies were not significantly different from those of other horses (p > 0.05). The lipoprotein phenotype in Caspian ponies may be useful for evaluating metabolic diseases.

    Weight gain is a common adverse effect associated with the use of most typical and atypical antipsychotic. Aim of this study was to investigate serum prolactin, leptin, cholesterol, triglyceride, lipoproteins, such high density lipoprotein (HDL), and low density lipoprotein (LDL) levels in patients with Parkinson's disease (PD)-related psychosis during long-term medication with atypical antipsychotic. The study population comprised 40 patients, who were divided into 4 groups: olanzapine (n=10), risperidone (n=10), seroquel (n=10) monotherapy, a group of 10 patients receiving only antiparkinson drugs and a control group of 8 healthy persons. The patients were evaluated at baseline and at the sixth and twelfth week according to the Positive and Negative Syndrome Scale (PANSS), body mass index (BMI), and fasting serum prolactin, leptin, lipids and lipoproteins levels. Treatment of patients with olanzapine caused marked increase of serum LDL, cholesterol, triglyceride, and leptin levels (prelationship between serum leptin, lipid levels and BMI. However, treatment of patients with seroquel did not cause changes in serum prolactin, leptin, lipids, and lipoproteins levels. Our results suggest that treatment of patients with PD-related psychosis with seroquel appears to have minimal influence on serum leptin, prolactin, lipids, lipoproteins and BMI compared with olanzapine and risperidone.

    Accumulating evidence suggests that fat distribution is a better predictor of cardiovascular disease than body mass index (BMI). The aim of this study was to investigate the association of android and gynoid fat percentages with lipid profiles to determine whether android and/or gynoid fat percentages are associated with serum lipid levels. A population-based cross-sectional study. Five thousand six hundred and ninety-six adults (20 years and older) who participated in the National Health and Nutrition Examination Survey 2003-2006. The regional body composition in the android and gynoid regions was defined by dual energy X-ray absorptiometry (DXA). The estimation of lipid risk profiles included total cholesterol, high-density lipoprotein (HDL) -cholesterol, low-density lipoprotein (LDL) -cholesterol and triglycerides (TG). Regardless of gender, android and gynoid body fat percentages were positively and significantly correlated with BMI and waist circumference. After adjustment for age, ethnicity, education, smoking, alcohol consumption, dyslipidaemia and BMI, increases in android fat percentage were significantly associated with total cholesterol, TG and HDL cholesterol in males, and total cholesterol, HDL cholesterol and LDL cholesterol in females. The gynoid fat percentages showed a positive correlation with total cholesterol in males, whereas gynoid fat accumulation in females showed a favourable association with TG and HDL cholesterol. The observed associations differed according to ethnic groups. Our results suggest that regional fat distribution in the android and gynoid regions have different effects on lipid profiles, and that fat in the android region, rather than the gynoid region, may be an important factor in determining the risk of cardiovascular disease. © 2014 John Wiley & Sons Ltd.

  13. INFLUENCE OF BIOPREPARATIONS FROM DRY SOYBEAN AND SUNFLOWER LECITHINS ON SERUM LIPIDS COMPOSITION

    Directory of Open Access Journals (Sweden)

    H. V. Dziak

    2014-04-01

    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.

    The effect of a single dose of whole body irradiation on the serum cholesterol content and fatty acid composition of serum lipids in rats was investigated. A change in the fatty acid composition of liver lipids was also observed. After 600 rad of irradiation, the cholesterol content increased, reached a maximum 3 days after irradiation, and then decreased. After irradiation, an increase in cholesterol content and a marked decrease in triglyceride content were observed, bringing about a change in the amount of total serum lipids. The fatty acid compositions of normal and irradiated rat sera were compared. The relative percentages of palmitic and oleic acids in total lipids decreased while those of stearic and arachidonic acids increased. Serum triglyceride had trace amounts of arachidonic acid and the unsaturated fatty acid component decreased after irradiation. On the other hand, unsaturated fatty acid in cholesterol ester increased after irradiation, while linoleic and arachidonic acids made up 29% and 22% in the controls and 17% and 61% after irradiation, respectively. The fatty acid composition of total liver lipids after irradiation showed a decrease in palmitic and oleic acids and an increase in stearic and arachidonic acids, the same trend as observed in serum lipid fatty acid. Liver cholesterol ester showed trace amounts of linoleic and arachidonic acids and an increase in short-chain fatty acid after irradiation. The major component of serum phospholipids was phosphatidylcholine while palmitostearyl lecithine and unsaturated fatty acid were minor components. Moreover, phosphatidylcholine and phosphatidylethanolamine were the major components of liver phospholipids, having highly unsaturated fatty acids. The changes in fatty acid composition were similar to the changes in total phospholipids. (J.P.N.)

  15. Subcellular localization of secondary lipid metabolites including fragrance volatiles in carnation petals

    Hudak, K.A.; Thompson, J.E.

    1997-01-01

    Pulse-chase labeling of carnation (Dianthus caryophyllus L. cv Improved White Sim) petals with [14C]acetate has provided evidence for a hydrophobic subcompartment of lipid-protein particles within the cytosol that resemble oil bodies, are formed by blebbing from membranes, and are enriched in lipid metabolites (including fragrance volatiles) derived from membrane fatty acids. Fractionation of the petals during pulse-chase labeling revealed that radiolabeled fatty acids appear first in microsomal membranes and subsequently in cytosolic lipid-protein particles, indicating that the particles originate from membranes. This interpretation is supported by the finding that the cytosolic lipid-protein particles contain phospholipid as well as the same fatty acids found in microsomal membranes. Radiolabeled polar lipid metabolites (methanol/ water-soluble) were detectable in both in situ lipid-protein particles isolated from the cytosol and those generated in vitro from isolated radiolabeled microsomal membranes. The lipid-protein particles were also enriched in hexanal, trans-2-hexenal, 1-hexanol, 3-hexen-1-ol, and 2-hexanol, volatiles of carnation flower fragrance that are derived from membrane fatty acids through the lipoxygenase pathway. Therefore, secondary lipid metabolites, including components of fragrance, appear to be formed within membranes of petal tissue and are subsequently released from the membrane bilayers into the cytosol by blebbing of lipid-protein particles

    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.

    Creutzfeldt-Jakob disease (CJD) is a rare, rapidly progressive, and fatal neurodegenerative disease affecting the central nervous system. Brain lipid homeostasis and oxidative stress seem to play an important role in the disease pathogenesis. But little was known whether serum lipids and uric acid (a natural antioxidant) levels changed in patients with prion disease. Here we retrospectively reviewed and compared the serum lipids and uric acid levels of 19 probable sporadic CJD patients and 26 healthy control subjects. We found that the serum uric acid levels in sporadic CJD patients were significantly lower than that in controls (P=0.01). Serum triglycerides, cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and apolipoprotein A1 (ApoA1) were similar in sporadic CJD patients and controls. However, LDL/HDL ratio was lower in sporadic CJD patients (P=0.003). The low serum uric acid and LDL/HDL ratio levels in sporadic CJD indicate that dysfunction in the lipid homeostasis and oxidative stress is associated with sporadic prion disease.

    Intravenous gene delivery via cationic lipidic vectors gives systemic gene expression particularly in the lung. In order to understand the mechanism of intravenous lipofection, a systematic study was performed to investigate the interactions of lipidic vectors with mouse serum emphasizing how serum affects the biophysical and biological properties of vectors of different lipid compositions. Results from this study showed that lipidic vectors underwent dynamic changes in their characteristics after exposure to serum. Addition of lipidic vectors into serum resulted in an immediate aggregation of vectors. Prolonged incubation of lipidic vectors with serum led to vector disintegration as shown in turbidity study, sucrose-gradient centrifugation analysis and fluorescence resonance energy transfer (FRET) study. Vector disintegration was associated with DNA release and degradation as shown in EtBr intercalation assay and DNA digestion study. Serum-induced disintegration of vectors is a general phenomenon for all cationic lipidic vectors tested in this study. Yet, vectors of different lipid compositions vary greatly in the rate of disintegration. There is an inverse correlation between the disintegration rate of lipidic vectors and their in vivo transfection efficiency. Vectors with a rapid rate of disintegration such as those containing dioleoyl-phosphatidylethanolamine (DOPE) poorly stayed in the lung and were barely active in transfecting cells. In contrast, cholesterol-containing vectors that had a rapid aggregation and a slow disintegration were highly efficient in transfecting cells in vivo. The results of this study explain why cationic lipidic vectors of different lipid compositions have a dramatic difference in their in vivo transfection efficiency. These results also suggest that the study of the interactions of lipidic vectors with serum may serve as a predictive model for the in vivo efficiency of a lipidic vector. Further study of the numerous interactions of

    Periodontal and cardiovascular diseases share some common underlying mechanisms. Hyperlipidemia is a major risk factor for cardiovascular diseases. This study sought to assess the association of hyperlipidemia and statin consumption with periodontal status. This cross-sectional study was conducted on 150 participants including 50 individuals with normal lipid profile (group C), 50 hyperlipidemic patients without drug therapy (group N), and 50 hyperlipidemic patients on drug therapy for a minimum of 3 months (group S). Periodontal parameters including plaque index (PI), clinical attachment level (CAL), bleeding on probing (BOP), and pocket depth (PD) were measured for all teeth except for the third molars. Serum levels of total cholesterol (TC), HDL, LDL, and triglycerides (TGs) were measured. The mean values of CAL and PD were significantly higher in the two hyperlipidemic groups compared with the C group (P < 0.005). Also, CAL and PD had significant associations with serum levels of TGs, LDL, and TC (P < 0.0001); PI in the group S was significantly lower than that in the other groups (P < 0.005). Hyperlipidemic patients showed higher values of periodontal parameters compared with the statin-treated and control groups. Lower PI in the group S may indicate the anti-inflammatory effect of statin. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    There has been recent interest in spicy foods and their bioactive ingredients for cardiovascular health. This study aims to explore relationship between spicy food consumption frequency and serum lipid profiles in a cross-sectional sample of older Chinese from China Health and Nutrition Survey (CHNS). A total of 1549 participant aged 65 years and above from CHNS 2009 were included in the analysis. Information on spicy food consumption was obtained using a questionnaire survey and 24h dietary recalls over three consecutive days combined with weighted food inventory. Fasting blood samples were analyzed for total cholesterol (TC), triglycerides, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (apoA1) and apolipoprotein B (apoB). Correlations between spicy food consumption frequency and serum lipid profiles were evaluated by multivariate linear regression models. The result shows a significant positive association between frequency of spicy food consumption estimated by the frequency question and daily spicy food intake calculated from 24h recall. After adjustment for potential lifestyle and dietary confounding factors, men with higher frequency of spicy food consumption showed higher apoA1 level, and lower ratio of LDL-C/apoB (p for trend food consumption was significantly associated with TC, LDL-C, apoB, LDL-C/HDL-C, and apoB/apoA1 in an inverse manner, and positively correlated with apoA1 level (p for trend food consumption frequency may favorably associated with some risk factors for cardiovascular diseases.

    Full Text Available Abstract Background Reference data for plasma lipids and blood pressure are not available for Asian Indian adolescents. This study aimed to develop representative age- and sex- specific percentile reference data for serum lipids [total cholesterol (TC, triglycerides (TG, low density lipoprotein cholesterol (LDL-C, high density lipoprotein cholesterol (HDL-C, non-HDL cholesterol] and blood pressure for urban Asian Indian adolescents aged 14–18 years. The sample consisted of 680 boys and 521 girls aged 14–18 years from the cross-sectional population survey, Epidemiological Study of Adolescents and Young Adults (ESAY for whom the data for serum lipid levels and blood pressure were recorded. Smoothed age- and sex- specific 5th, 10th, 25th, 50th, 75th, 85th, 90th and 95th percentiles where derived using LMS regression. Results Percentile-based reference data for serum lipids and blood pressure are presented for adolescent Asian Indian boys and girls for the first time. Asian Indian adolescents had lower levels of serum TC, LDL-C and HDL-C and higher TG than their counterparts in the USA. Interesting trends in TC and HDL-C levels where observed, which might reflect changes in dietary pattern and physical activity in this age group in India. Conclusion These reference data could be used to identify adolescents with an elevated risk of developing dyslipidemia, hypertension and cardiovascular disorders, to plan and implement preventive policies, and to study temporal trends.

    Wistar rats of 6-8 weeks in age weighing between 120-150 g were exposed to the fixed doses of each of the carbamate pesticides such as cartap (50% LD(50)) and carbofuran (50% LD(50)) as well as a combination of these two with 25% LD(50) of each for one week. The effect of treatments was studied in terms of serum lipid parameters such as high-density lipoprotein, total cholesterol, triglyceride, low-density lipoprotein and very low-density lipoprotein. Treatment with individual doses of carbofuran (50% LD(50)) and cartap (50 % LD(50)) caused significant alterations in the levels of serum lipid parameters. The pesticides treatment resulted in marked decrease in the level of serum high-density lipoprotein where as that of other lipids got significantly elevated. Further, the rats exhibited relatively higher impact of pesticides when treated with the compounds in combination (25 % LD(50) of each). The results indicated that these compounds when used together may exert enhanced effect on the levels of serum lipids in rat.

    Cocoa products, which are rich sources of flavonoids, have been shown to reduce blood pressure and the risk of cardiovascular disease. Dark chocolate contains saturated fat and is a source of dietary calories; consequently, it is important to determine whether consumption of dark chocolate adversely affects the blood lipid profile. The objective was to examine the effects of dark chocolate/cocoa product consumption on the lipid profile using published trials. A detailed literature search was conducted via MEDLINE (from 1966 to May 2010), CENTRAL and ClinicalTrials.gov for randomized controlled clinical trials assessing the effects of flavanol-rich cocoa products or dark chocolate on lipid profile. The primary effect measure was the difference in means of the final measurements between the intervention and control groups. In all, 10 clinical trials consisting of 320 participants were included in the analysis. Treatment duration ranged from 2 to 12 weeks. Intervention with dark chocolate/cocoa products significantly reduced serum low-density lipoprotein (LDL) and total cholesterol (TC) levels (differences in means (95% CI) were -5.90 mg/dl (-10.47, -1.32 mg/dl) and -6.23 mg/dl (-11.60, -0.85 mg/dl), respectively). No statistically significant effects were observed for high-density lipoprotein (HDL) (difference in means (95% CI): -0.76 mg/dl (-3.02 to 1.51 mg/dl)) and triglyceride (TG) (-5.06 mg/dl (-13.45 to 3.32 mg/dl)). These data are consistent with beneficial effects of dark chocolate/cocoa products on total and LDL cholesterol and no major effects on HDL and TG in short-term intervention trials.

    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.

    To determine the effects of fasting during the month of Ramadan on fetal development and maternal serum cortisol and lipid profile. This study was performed in Obstetrics and Gynecology Department of Gaziantep University Hospital, between 23 September 2006 and 23 October 2006 (during the month of Ramadan). Thirty-six consecutive healthy women with uncomplicated pregnancies of 20 weeks or more, who were fasting during Ramadan, were included in the study group (group 1). The control group (group 2) consisted of 29 healthy pregnant women, who were not fasting during the study period. For evaluating Ramadan's effect on fetus, Doppler ultrasonography was performed on all subjects in the beginning and then once a week until the end of Ramadan for the following measurements: increase of fetal biparietal diameter (BPD), increase of fetal femur length (FL), increase of estimated fetal body weight (EFBW), fetal biophysical profile (BPP), amniotic fluid index (AFI), and umbilical artery systole/diastole (S/D) ratio. Maternal serum cortisol, triglyceride, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), very low density lipoprotein (VLDL), and LDL/HDL ratio were also evaluated before and after Ramadan. No significant difference was found between the two groups for the fetal age, maternal weight gain (kilogram), estimated fetal weight gain (EFWG), fetal BPP, AFI, and umbilical artery S/D ratio. In the fasting group, the maternal serum cortisol levels on day 20 were significantly higher than the initial levels obtained 1 week prior to Ramadan (p Ramadan. HDL levels showed a slight increase, but LDL/HDL ratios were significantly decreased in fasting group (p Ramadan. No untoward effect of Ramadan was observed on intrauterine fetal development.

    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

    Objectives: To investigate the relationship between lipid levels and oxidative stress index in healthy young adults. Methods: The study was camed out at the Department of Emergency Service, Faculty of Medicine, Cumhuriyet University, Sivas, Turkey, between January 2011 and July 2012. A total of 100 healthy adult volunteers were enrolled in the study. Venous blood samples (10 ml) were collected from all individuals, and serum lipid parameters, total antioxidant capacity and total oxidative levels were studied. SPSS 15 was used for statistical analysis. Results: Overall, there were 84 (84%) males and 16 (16%) females. The mean age of the male population was 30+-3 years, while that of the females was 31+-3 years. Overall age ranged from 25 to 35 years. A statistically significant correlation was found between the oxidative stress index and serum cholesterol (p<0.001; r=0.596), triglyceride (p<0.001; r=0.476) and low-density lipoprotein levels (p<0.001; r=0.318). However, no significant correlation was found between oxidative stress index and serum high-density lipoprotein levels (p=0.564; r=0.058). Conclusion: The results showed that even at an early age, there is a direct linear correlation between oxidative stress and serum lipid levels. (author)

    Objective: To investigate the relationships between changes of serum sex hormones levels and protein-lipid metabolism in patients with ulcerative colitis. Methods: Serum levels of estradiol (E 2 ) pregnenedione (P), prolactin(PRL), luteinizing hormone (LH), follicle-stimulating hormone (FSH) (with CLIA), sree testos (T, with RIA) and total-protein (TP), albumin (Alb), globulin (G), albumin/globulinratio (A/G) total-cholesterd (TC), high density lipoprotein cholesterols (LDL-C) (with biochemistry were determined in 72 patients) with ulcerative colitis and 72 controls. Results: The serum levels of T, LH, FSH, TP, Alb, A/G, TC, LDL-C in patients with ulcerative colitis were significantly lower than those in controls (P 2 , PRL in patients with ulcerative colitis were significantly higher than those in controls (P 2 were negatively correlated with TP, A/G and TC (P 2 levels in the female sex (P>0.05) as well as between LH, FSH and T levels in the male sex (P>0.05). Conclusion: The abnormal serum levels of sex hormone might contribute to the development of hypoproteinaemia and lowered lipid levels in patients with ulcerative colitis. Treatment with correction of serum sex hormones levels might be beneficial to the patients. (authors)

    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.

    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.

    To investigate the dietary phytosterol intake of elderly women in three different cities of China, and to compare the main dietary sources, so that to discuss the relationship of dietary phytosterol intake and serum lipids. Based on the dietary pattern, women more than 50 years old from Beijing, Hefei and Urumchi were chosen as testers, 80 - 100 people for each city respectively. The dietary survey was done by continues 24 hours review of two days, the plant food were collected and the phytosterol content (include beta-sitosterol, campesterol, stigmasterol, sitostanol) were analyzed by GC methods, the total phytosterols content were calculated. The dietary phytosterol intake were calculated and serum lipids were also analyzed in all the testers. Testers from Beijing, Hefei and Urumchi were 100, 101 and 84 respectively. The average dietary phytosterol intake of people in Beijing and Hefei were 340.3 mg/d and 313.5 mg/d, the main sources were plant oil and cereals, while the average dietary phytosterol intake of people in Urumchi were 550.4 mg/d, higher than the other two cities (t values were 9.369, 10.420, respectively, both P values phytosterol intake). The laboratory results showed, testers in Urumchi had significantly lower serum TC content ((4.04 +/- 0.78) mmol/L) than that in Beijing ((4.89 +/- 0.91) mmol/L) and Hefei ((4.71 +/- 0.83) mmol/L) (t value were 6.766 and 5.401 respectively, both P values phytosterol intake in elder women in three cities, higher, phytosterol intake seemed to contribute to lower serum lipids.

    Data on whether periodontal therapy affects serum CRP levels are inconclusive. The aim of this study was to determine if nonsurgical periodontal therapy has any effect on CRP and serum lipid levels in patients with advanced periodontitis. Thirty-six systemically healthy patients, ≥ 40 years of age and with advanced periodontitis, were recruited for the study. Patients were randomized consecutively to one of two groups: the treatment group (n = 18) or the control group (n = 18). Treated subjects received nonsurgical periodontal therapy, which included oral hygiene instructions and subgingival scaling and root planing. Systemic levels of inflammatory markers [C-reactive protein (CRP) and the lipid profile] were measured at baseline and 3 mo after periodontal therapy. Nonsurgical periodontal therapy in the treatment group resulted in a significant reduction in the serum CRP level. The average CRP level decreased from 2.3 mg/dL at baseline to 1.8 mg/dL (p periodontal therapy. The average reduction (95% confidence interval) in CRP was 0.498 (95% confidence interval = 0.265-0.731). In the treatment group, the reduction in CRP was significantly, linearly and directly correlated with the reduction in the plaque index, the gingival index and the percentage of sites with pocket depth ≥ 7 mm (Pearson correlation coefficient = 0.746, 0.425 and 0.621, respectively). Nonsurgical periodontal therapy had no effect on the lipid parameters. This study demonstrated that nonsurgical periodontal therapy results in a significant reduction in the serum CRP level. The effect of this outcome on systemic disease is still unknown. © 2011 John Wiley & Sons A/S.

    Objectives To quantitate and compare the associations of various body composition measurements with serum metabolites and to what degree genetic or environmental factors affect obesity-metabolite relation. Methods Body mass index (BMI), waist circumference (WC), lean body mass (LBM), percent body fat (PBF), fasting serum high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG), total cholesterol (TC), glucose, insulin and lifestyle factors were assessed in 903 twins from Chinese National Twin Registry (CNTR). Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated from fasting serum glucose and insulin. Linear regression models and bivariate structural equation models were used to examine the relation of various body composition measurements with serum metabolite levels and genetic/environmental influences on these associations, respectively. Results At individual level, adiposity measurements (BMI, WC and PBF) showed significant associations with serum metabolite concentrations in both sexes and the associations still existed in male twins when using within-MZ twin pair comparison analyses. Associations of BMI with TG, insulin and HOMA-IR were significantly stronger in male twins compared to female twins (BMI-by-sex interaction p = 0.043, 0.020 and 0.019, respectively). Comparison of various adiposity measurements with levels of serum metabolites revealed that WC explained the largest fraction of variance in serum LDL-C, TG, TC and glucose concentrations while BMI performed best in explaining variance in serum HDL-C, insulin and HOMA-IR levels. Of these phenotypic correlations, 64–81% were attributed to genetic factors, whereas 19–36% were attributed to unique environmental factors. Conclusions We observed different associations between adiposity and serum metabolite profile and demonstrated that WC and BMI explained the largest fraction of variance in serum lipid profile and insulin

It can be said this study aimed in assessing percentile curves of serum lipid profile about 6-18 years old students of Birjand.Method: The present cross-sectional study was done on 4168 students of Birjand aged 6-18 years. They were classified into three age groups 6-10 and 15-18 and 11-14 years. The 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles of lipids (cholesterol, LDL, HDL and triglycerides were determined by sex for different age groups.Result: The 5th, 10th, 25th, 50th, 75th, 90th and 95th percentiles for cholesterol, LDL, HDL, and TG were 114,123, 138, 157, 176, 197, 210; 54, 59, 71, 86, 102, 119, 131; 33, 36, 41, 48, 56, 64, 68 and 43, 49, 61, 78, 103, 138, 164, respectively. Conclusion: Percentiles of lipid in kids of Birjand are different in comparison with reference percentiles of the U.S and also Tehran. Triglycerides and HDL in children and adolescents of Birjand were higher and lower, respectively than the Americans. This could be due to racial differences and environmental factors such as nutrition and sedentary life style. This should be considered in interpretation of normal and abnormal values and determination of dyslipidemia in children and adolescents. Take the regional percentiles of serum lipids for Iranian children and adolescents recommended by examining a sufficient number of samples.

    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.

    Atherosclerosis is a disease of adult patients, however, it begins in childhood and progresses from fatty streaks to raised lesions in arteries in adolescence and young adults. Clinical manifestation of atherosclerosis in adulthood depends on the risk factors such as: lipid disorders, obesity, hypertension, smoking habits and family history of CHD. High serum homocysteine concentration is increasingly recognised as a new risk factor for atherosclerosis and other vascular diseases. Atherogenic effect of homocystein is related to cytotoxin action on the endothelial cells and their function. The aim of this study was to estimate relations between the homocysteine serum concentration and the lipid levels in children with atherosclerosis risk factors. The study was carried out on 48 children with atherosclerosis risk factors. The control group consisted of 25 healthy childrens. Total cholesterol (TC), Triglycerides (TG), HDL-C, LDL-C were determined by enzymatic method. Concentration of homocysteine was estimated by immunoenzymatic method (ELISA). Obesity, lipid disorders, and hypertension were the most frequent risk factors in the investigated children. Statistically significant higher concentration of TC, LDL-C, TG and lower HDL-C were observed in children with atherosclerosis risk factors. No significant differences in homocystein concentration were observed in the investigated groups, but homocystein concentration was significantly higher in group of children with atherosclerosis risk factors. We observed that increased number of the risk factors is followed by high homocystein concentration in the serum.

    To investigate the effect of ganoderma lucidum polysaccharides on blood lipid and lipoperoxidation from the experimental hyperlipidemic rats. 50 rats were randomly divided into normal group, hyperlipidemia control group, experimental group 1, 2 and 3 in which the rats were treated with ganoderma lucidum polysaccharides at dosages of 200 mg x kg(-1) and 400 mg x kg(-1) and 800 mg x kg(-1) respectively. Apart from the rats in control group, all the rats in other groups were fed with high fat forage for 30 days. The blood was collected from the tails of rats for measuring the serum TC, TG, HDL-C, LDL-C, GSH-Px, SOD and LPO. Ganoderma lucidum polysaccharides could significantly decrease the serum contents of TC, TG, LDL-c in the experimental hyperlipidemic rats (P < 0.01), and markedly increase the level of serum HDL-C (P < 0.05), Mean Level of blood LPO in the experimental groups treated by ganoderma lacidum polysaccharides at different dosages were much lower than that in hyper lipidema group, and the GSH-Px and SOD activities of blood in the group of ganoderma were much higher than those in hyperlipidema group. Ganoderma can regulate lipid metabolism, enhance the antioxidation and reduce the lipid peroxidation in the rats with hyperlipidemia.

    To determine the best cut-offs of body mass index for identifying alterations of blood lipids and glucose in adolescents. A probabilistic sample including 577 adolescent students aged 12-19 years in 2003 (210 males and 367 females) from state public schools in the city of Niterói, Southeastern Brazil, was studied. The Receiver Operating Characteristic curve was used to identify the best age-adjusted BMI cut-off for predicting high levels of serum total cholesterol (> or =150 mg/dL), LDL-C (> or =100 mg/dL), serum triglycerides (> or =100 mg/dL), plasma glucose (> 100 mg/dL) and low levels of HDL-C (international and two American. The most prevalent metabolic alterations (>50%) were: high total cholesterol and low HDL-C. BMI predicted high levels of triglycerides in males, high LDL-C in females, and high total cholesterol and the occurrence of three or more metabolic alterations in both males and females (areas under the curve range: 0.59 to 0.67), with low sensitivity (57%-66%) and low specificity (58%-66%). The best BMI cut-offs for this sample (20.3 kg/m(2) to 21.0 kg/m(2)) were lower than those proposed in the references studied. Although BMI values lower than the International cut-offs were better predictor of some metabolic abnormalities in Brazilian adolescents, overall BMI is not a good predictor of these abnormalities in this population.

    Developing host digestion-resistant starches to promote human health is of great research interest. Chemically modified starches (CMS) are widely used in processed foods and although the modification of the starch molecule allows specific reduction in digestibility, the metabolic effects of CMS have been less well described. This short-term study evaluated the impact of enzymatically modified starch (EMS) on fasting and postprandial profiles of blood glucose, insulin and lipids, and serum metabolome in growing pigs. Eight jugular-vein catheterized pigs (initial body weight, 37.4 kg; 4 months of age) were fed 2 diets containing 72% purified starch (EMS or waxy corn starch (control)) in a cross-over design for 7 days. On day 8, an 8-hour meal tolerance test (MTT) was performed with serial blood samplings. Besides biochemical analysis, serum was analysed for 201 metabolites through targeted mass spectrometry-based metabolomic approaches. Pigs fed the EMS diet showed increased (Pmetabolome profiling identified characteristic changes in glycerophospholipid, lysophospholipids, sphingomyelins and amino acid metabolome profiles with EMS diet compared to control diet. Results showed rapid adaptations of blood metabolites to dietary starch shifts within 7 days. In conclusion, EMS ingestion showed potential to attenuate postprandial raise in serum lipids and suggested constant alteration in the synthesis or breakdown of sphingolipids and phospholipids which might be a health benefit of EMS consumption. Because serum insulin was not lowered, more research is warranted to reveal possible underlying mechanisms behind the observed changes in the profile of serum lipid metabolome in response to EMS consumption.

    Children with end-stage renal disease (ESRD) suffer from dyslipidemia and hyperuricemia that might play a causal role in the progression of cardiovascular disease (CVD). The aim of the study is to assess the effects of Vitamin C supplementation on uric acid, ascorbic acid, and serum lipid levels among children on hemodialysis (HD). This prospective study was conducted in the pediatric nephrology unit at Menoufia University Hospital. The study included a total of 60 children with ESRD on maintenance HD therapy. They were divided into two groups: Group I (supplemented group, n = 30) received intravenous Vitamin C supplementation and Group II (control, n = 30) received placebo (intravenous saline) for three months. The results are shown as a mean ± standard deviation. Statistical evaluation was performed by SPSS software (version 11.5) using paired t-test. After supplementation with Vitamin C, the serum Vitamin C and high-density lipoprotein levels increased significantly with a significant reduction in the levels of serum uric acid, cholesterol, low-density lipoproteins, and triglyceride at the end of the study period. No significant changes were observed in the control group. Vitamin C can serve as a useful urate lowering medicine in HD patients to avoid complications of hyperuricemia. Furthermore, it had favorable effects on the lipid profile. This improvement can be considered as a preventive strategy in the progression of CVD in HD patients. Vitamin C supplementation improves ascorbic acid deficiency in these patients.

    Full Text Available Context: Increased quantities of glycoconjugates such as Total Sialic Acid (TSA and Lipid-bound Sialic Acid (LSA have been detected in the plasma and serum of patients with various malignancies, indicating their usefulness in diagnosis or monitoring of the treatment modality. Aims: (1 To estimate and compare the serum TSA and LSA levels in Oral Squamous Cell Carcinoma (OSCC patients before and after radiotherapy, as also in healthy individuals. (2 To determine the correlation, if any, between Tumor-Node-Metastasis (TNM staging and levels of TSA and LSA. (3 To determine the use of serum TSA and LSA as biomarkers of OSCC. Settings and Design: The study was designed as a case-control study and was undertaken in a dental college and cancer hospital. Materials and Methods: It was planned to estimate the serum TSA and LSA levels of 20 healthy individuals and of 20 OSCC patients, spectrophotometrically; before starting and one month after completion of radiotherapy. Statistical Analysis: The Statistical Package for Social Sciences (SPSS Version 10.0 was used. Results: The mean serum TSA and LSA levels in OSCC patients decreased significantly after radiotherapy; however, they were still higher than the levels in the controls. In untreated OSCC patients, a statistically significant positive correlation was observed between the TNM stage of the disease and the serum TSA levels; but the same was not found between the TNM stage of the disease and the serum LSA levels. In OSCC, the serum TSA and LSA levels had a positive relationship with the TNM stages. These levels decreased significantly after radiotherapy. Conclusion: Serum TSA and LSA can be utilized as potential diagnostic and prognostic indicators in OSCC.

    Young male Wistar rats (mean body mass 200 g) adapted to a 12:12 h light:dark regimen (7 a.m. to 7 p.m., 7 p.m. to 7 a.m.) were X-irradiated at 3-h intervals during one day with doses of 2.39 or 14.25 Gy and were killed 48 or 24 h afterwards. Nonesterified fatty acids were determined in their serum and white and brown adipose tissue, and triacylglycerols, phospholipids and total cholesterol in their serum and liver. The reaction of serum and tissue lipids during the day varied after both non-lethal and lethal irradiation. After non-lethal exposure, most of the curves, as regards their course, the presence of rhythm and their oscillation properties, concurred with the lipid indicator curves in the control series and indicated that the organism's response is dependent on the time of day. Circadian variation of serum and adipose tissue nonesterified fatty acid levels, the liver triacylglycerol concentration and the adrenal cholesterol concentration in lethally irradiated animals showed no significant dependence on the time of application of the stimulus. An analysis of circadian variation of the effectiveness of a stimulus facilitates understanding of the organism's reactivity better than a single examination in the morning. (author)

    Full Text Available Background. Colorectal cancer mostly arises from the polyps of colon. The aim of our study was to examine the association of body mass index (BMI and serum lipids with the colorectal polyps in old Chinese people. Methods. The risk of developing colorectal polyps was studied in 244 subjects (212 men and 32 women, 74.63 ± 11.63 years old who underwent colonoscopy for the first time from January 2008 to July 2012 at the Navy General Hospital, Beijing, China. According to the results of colonoscopy, all the subjects were divided into 112 normal control, 38 right colorectal polyps, 53 left colorectal polyps, and 41 both right and left colorectal polyps groups. The total plasma cholesterol, plasma triglyceride, plasma creatinine concentration, blood urinary nitrogen, and fasting glucose were determined using a multichannel analyzer. Results. There were significant differences among normal control, right colorectal polyps, left colorectal polyps, and both right and left polyps groups, which were the BMI, total cholesterol, triglycerides, creatinine, and urinary nitrogen. In binary logistic regression analysis, there were two risk factors associated with the occurrence of colorectal polyps, which included BMI and systolic blood pressure. Conclusions. Colorectal polyps were significantly associated with increased BMI, total cholesterol, and triglycerides levels.

    A growing body of evidence suggests that beta-glucan derived from oats or barley can reduce cardiovascular disease risk through reductions in serum lipids. However, the effects of beta-glucan on lipid changes in hypercholesterolemic patient groups are inconsistent. The objective of this study was to identify and quantify the effect of beta-glucan, a marker of water-soluble fiber, on various lipid parameters and glucose level in hypercholesterolemic subjects. We performed a comprehensive literature search to identify the relevant randomized controlled trials (RCTs) that investigated the effects of beta-glucan consumption in hypercholesterolemic subjects. Mean differences (MDs) and 95% confidence intervals (CIs) were calculated for net changes in lipid concentrations by using fixed-effects or random-effects models according to heterogeneity. Publication bias, sensitivity analysis and subgroup analyses were also performed. Seventeen eligible RCTs with 916 subjects were included in the meta-analysis. The pooled result showed that beta-glucan consumption in hypercholesterolemic population significantly lowered the total cholesterol (TC) (MD, -0.26 mmol/L; 95% CI, -0.33 to -0.18; P consumption significantly decreased TC and LDL-cholesterol concentrations but did not affect TG, HDL-cholesterol, and glucose concentrations in hypercholesterolemic subjects.

    We investigated the effects of ascorbic acid (AsA) supplementation on lipid peroxidation and the lipid content in the liver and serum of magnesium (Mg)-deficient rats. Eighteen 3-week-old male Sprague-Dawley strain rats were divided into 3 groups and maintained on a control diet (C group), a low-Mg diet (D group), or a low-Mg diet supplemented with AsA (DA group) for 42 d. At the end of this period, the final body weight, weight gain, and serum Mg concentrations were significantly decreased in the Mg-deficient rats. Further, dietary AsA supplementation had no effect on the growth, serum Mg concentration, Mg absorption, and Mg retention. The serum concentration of AsA was significantly lower in the D group than in the C group but was unaltered in the DA group. The levels of phosphatidylcholine hydroperoxide (PCOOH) in the serum and of triglycerides (TGs) and total cholesterol (TC) in the serum and liver were significantly higher in the D group than in the C group. The serum PCOOH, liver TG, and liver TC levels were decreased in the DA group. These results indicate that Mg deficiency increases the AsA requirement of the body and that AsA supplementation normalizes the serum levels of PCOOH and the liver lipid content in Mg-deficient rats, without altering the Mg status.

    Full Text Available Materials and Methods: In this analytic, cross-sectional study, we chose a total often mature Iranian male goats that comprised a homogenous group through simplerandom sampling. Blood samples were taken from the jugular vein; the sera wereseparated and subsequently used for measurement of serum lipids, lipoproteins andtestosterone levels. In addition, we collected semen from the animals and evaluatedthe seminal characteristics. We also performed histological and anatomical assessmentsof the testes.Results: The findings demonstrated that serum levels of high density lipoprotein(HDL-c had a significant positive correlation with interstitial testicular tissue area(r=0.73; p<0.001, seminiferous tubule area (r=0.61; p<0.01, the number of Leydigcells (r=0.53; p<0.05, the diameter of the Leydig cell nuclei (r=0.54; p<0.05,scrotal circumference (r=0.83; p<0.001, testis weight (r=0.72; p<0.001, the numberof live, normal sperm (r=0.94 ; p<0.001 and serum testosterone levels (r=0.88;p<0.001. Significant but negative correlations were found between serum triglycerideconcentration and seminiferous tubule area (r=-0.53; p<0.05, the diameterof the Leydig cell nuclei (r=-0.55; p<0.05, testis weight (r =-0.64; p<0.01, totalsperm number (r=-0.82; p<0.001, number of live, normal sperm (r=-0.55; p<0.05and serum testosterone levels (r=-0.79; p<0.001. In addition, a significant negativecorrelation was observed between serum very low density lipoprotein (VLDL-cconcentration and the percent of live sperm (r=-0.67; p<0.01, and serum testosteronelevels (r=-0.65; p<0.01.Conclusion: The present results indicated that among serum lipids only the levelsof HDL-c positively correlated with testicular parameters. High serum triglyceridelevels exerted direct adverse effects at the testicular level, which was mainly observedin the seminiferous tubules (STs, characterization of Leydig cells and semenquality.

    Full Text Available Hepatotoxicity is one of the clinically adverse effects of ecstasy (3, 4-methylenedioxymethamphetamine; MDMA consumption. The detoxification tissue, liver, plays a central role in maintaining circulating levels of glucose and lipid. Hypoglycemia and hypotriglyceridemia have been reported due to ecstasy abuse. Ghrelin is a 28-amino-acid peptide secreted predominantly from the stomach. It has been demonstrated that ghrelin has hepatoprotective effects and is able to increase blood glucose concentration. In the current study, we explored the effect of hepatotoxic dose of MDMA and therapeutic use of exogenous ghrelin on the serum levels of glucose and lipids in four groups of rats. MDMA caused a severe and transient reduction in circulating levels of glucose and triglyceride and increased serum LDL. However, cholesterol and HDL levels remained unchanged. Meanwhile, altered hepatic architecture was observed with intracellular vacuolation that may indicate intracellular accumulation of lipid droplets. In addition, following ghrelin administration, the blood sugar levels improved and LDL levels returned to the baseline value, and ghrelin treatment did not improve triglycerides levels. These results showed that MDMA causes hypoglycemia, hypotriglyceridemia, and hyper LDL-cholesterolemia. To our knowledge, this is the first report showing ghrelin administration could improve hypoglycemia and normalize LDL levels induced by MDMA and partially restore hepatic architecture.

    Abnormalities in serum lipid and lipoprotein levels are recognized major modifiable cardiovascular disease and essential hypertension risk factors. The objective of this study was to examine the serum lipid patterns of newly diagnosed hypertensive patients attending a tertiary healthcare centre in South East Nigeria. Methods. Two hundred and fifty newly diagnosed adult hypertensive patients and an equal number of age- and sex-matched controls without hypertension were consecutively recruited from the Medical and General Outpatient Clinics of Nnamdi Azikiwe University Teaching Hospital, Nnewi. Result. 126 males and 124 females were in each of the two groups. Mean age was comparable in both groups. Hypertensives had significantly higher mean systolic blood pressure, diastolic blood pressure, body mass index, waist circumference, waist-hip ratio, and fasting blood sugar than the controls. The mean TC, TG, and LDL-C were significantly higher among the hypertensives. The mean HDL-C was comparable; P = 0.8. Among the hypertensive subjects, there was statistically significant positive correlation between BMI and TC; LDL-C and TG; WC and TG; FBS and TC; LDL-C and TG. HDL-C showed a statistically significant inverse correlation with WHR in hypertensives. Conclusion. This study showed that lipid abnormalities are highly prevalent among newly diagnosed hypertensives in South-East Nigeria.

    This study compared the lipid profile of women runners with menstrual cycle irregularities with their normally menstruating counterparts. Relationships among selected steroid hormones and serum lipid levels in 10 eumenorrheic (EU) and 8 oligo-/amenorrheic (O/A) women runners and 6 eumenorrheic controls (CON) were examined. Serum 17 beta-estradiol (E2), progesterone (Prog), and dehydroepiandrosterone-sulfate (DHEAS) concentrations were determined in daily blood samples for 21 days, and integrated concentrations were calculated. Fasting blood samples were analyzed for total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), HDL2, HDL3, triglycerides (Trig), and apolipoproteins A-1, A-II, and B. The O/A group had significantly lower E2 and Prog than EU or CON groups. Women in the CON group had lower HDL-C and HDL3 than the runners. With all women grouped together, E2 was not significantly correlated with any measured blood lipid parameters. On the other hand, DHEAS was significantly correlated with HDL-C, HDL2, and apolipoprotein A-I. These data demonstrate that women runners, regardless of menstrual cycle status, exhibit higher HDL-C concentrations than CON and supports previous research reporting a positive association between DHEAS and HDL-C.

    Antioxidants are effective in prevention and treatment of cardiovascular diseases. Lavandula officinalis possesses antioxidant activity, therefore, in this study; the effects of Lavandula officinalis extract were investigated on serum lipids levels of rats. Experimental mature male Wistar rats were treated with 100, 200 or 400 mg/Kg/day of lavender ethanolic extract or distilled water for 25 days via gastric gavage (n=8 each group). At the end of 25th day, the serum cholesterol, triglyceride, HDL, LDL and VLDL levels, as well as atherogenic indices were determined in rats’ serum. The ethanolic extract of lavender decreased serum cholesterol, triglyceride, LDL and VLDL levels in 100 mg/Kg group (p=0.03, p=0.001, p=0.001, p=0.001, respectively). Serum HDL level increased in 100 mg/Kg/day group (p=0.01). Lavender extract decreased LDL/HDL level at doses of 100 and 200 mg/Kg/day (p=0.001, p=0.001, respectively). The TG/HDL levels decreased in experimental groups with doses of 100 and 200 mg/Kg/day (p=0.001, p=0.001, respectively). Lavandula officinalis extract exerts hypolipidemic effect in rats and might be beneficial in hyperlipidemic patients. PMID:25587318

    Objective: To compare serum lipid profile in different ultrasonographic grades of non alcoholic fatty liver disease (NAFLD). Study Design: Cross sectional study. Place and Duration of Study: PNS SHIFA hospital, Karachi, from Oct 2015 to Jul 2016. Material and Methods: Seventy three adults of either gender were consecutively inducted after diagnosis of non alcoholic fatty liver disease (NAFLD) on ultrasonography (USG). These individuals were further classified into grade I, II and III of NAFLD depending on US findings. Fasting blood sample of all the subjects was analyzed for serum fasting lipid profile comprising of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C). Serum non HDL cholesterol (nonHDL-C) was calculated by subtracting HDL-C from TC. Results: Among 73 subjects with NAFLD, 42.5%, 37% and 20.5% had grade I, II and III NAFLD respectively. All parameters showed significant increase in frequency of abnormal results with increasing grade of NAFLD except TG. Significant difference was found in mean TC (p=0.000), LDL-C (p=0.000), HDL-C (p=0.005) and nonHDL-C (p=0.000) between grades of NAFLD. Post hoc analysis revealed that only mean nonHDL-C was significantly different amongst all the grades of NAFLD. Conclusion: The increasing severity of NAFLD was found associated with increased frequency of dyslipidemia. Though most frequent dyslipidemia in NAFLD was low serum HDL-C followed by hypertriglyceridemia, only serum nonHDL-C was statistically different amongst all the grades of NAFLD. (author)

    Breast cancer is a disease with diverse clinical symptoms, molecular profiles, and its nature to response its therapeutic treatments. Radiotherapy (RT), along with surgery and chemotherapy is a part of treatment in breast cancer. The aim of present study was to investigate pre and post treatment effects of radiotherapy in serum fatty acids and its lipids profile in patients with breast cancer. In this comparative as well as follow up study, Serum fatty acids were performed by gas chromatography to investigate fatty acids and Microlab for analysis of lipid profile. Among serum free and total fatty acids the major saturated fatty acids (SFAs) in serum lipids of breast cancer patients (pre and post treated) were stearic acid (18:0) and palmitic acid (16:0). These fatty acids contributed about 35-50% of total fatty acids. The decreased concentrations of linoleic acid (C18:2) and arachidonic acid (C20:4) with a lower ratio of C18:2/C18:1 was found in pretreated breast cancer patients as compared to controls. The n-3/n-6 ratio of breast cancer patients was decreased before treatment but it was 35% increased after treatment. In addition, plasma activity of D6 desaturase was increased in the breast cancer patients, while the activity of D5 desaturase was decreased. Increased levels of SFAs, monounsaturated fatty acids (MUFAs) and decreased polyunsaturated fatty acids (PUFAs) levels in breast cancer patients (pre and post treated) as compared to controls. Serum total cholesterol (TC) (224.4 mg/dL) and low density lipoprotein cholesterol (LDL-C) (142.9 mg/dL) were significantly increased in pretreated breast cancer patients but after the radiotherapy treatment, the TC (150.2 mg/dL) and LDL-C (89.8 mg/dL) were decreased. It seems that RT would have played a potential role in the treatment of BC. After RT the serum levels of PUFAs, TC, and LDL-C are improved. Our study reinforces the important role of RT in the management of BC. The level of PUFAs, TC, and LDL-C can be

    This study aimed at investigating the relationship between the lipid index (WS) in the examined cadets and duration of exposure to +Gz in the human centrifuge. The study involved 19 first-year cadets of the Polish Air Force Academy in Dęblin. Tests in the human centrifuge were repeated twice, i.e. prior to (test I) and 45 days after (test II). After exposure to +Gz, the examined cadets were divided into 2 groups. Group I (N=11) included cadets subjected to a shorter total duration of exposure to +Gz, while group II (N=8) included cadets with a longer total duration of exposure to +Gz. Total cholesterol (TC), high density lipoprotein (HDL), triglycerides (TG), and apolipoproteins A1 and B were assayed in blood serum prior to (assay A) and after (assay B) both exposures to +Gz. Low density lipoprotein (LDL) level was estimated from the Friedewald formula. WS is an own mathematical algorithm. WS was higher in group II, assay A - 10.0 and B - 10.08 of test I in the human centrifuge than in group I where the WS values were 6.91 and 6.96, respectively. WS was also higher in group II in assay A - 10.0 and B -10.1 of test II in the human centrifuge than in group I - 6.96 and 6.80, respectively. The higher value of WS in group II, both after the first and second exposure to +Gz in human centrifuge, in comparison with group I, indicated its usefulness for determination of the maximum capability of applying acceleration of the interval type during training in the human centrifuge.

    We investigated the circadian variation of serum thyrotropin (TSH), thyroxine (T 4 ), triiodothyronine (T 3 ), reverse triiodothyronine (rT 3 ), corticosterone (B) and lipids in male Wistar rats after one-week starvation. Starvation decreased the TSH level and eliminated its 24-h rhythm. The rhythmicity of oscillations of T 3 and B was maintained. Starvation led to a shift in the acrophase of 24-h T 3 and B oscillation and induced the circadian rhythm of T 4 . The T 3 , T 4 and mesor values were lower, while for rT 3 and B they increased. Lipid concentrations remained unchanged in both experimental and control rats. (author). 27 refs, 3 figs, 2 tabs

    Objective: To study the changes of serum lipid of pre-and post-treatment by Levothyroxine(LT 4 ) for patients with subclinical hypothyroidism (SHT) induced by post-radiotherapy nasopharyngeal carcinoma(NPC). Methods: From Nov. 1998 to Nov. 2002, 76 NPC pathologically confirmed patients were treated by radiotherapy. The total dose of thy- ;old was 45Gy-60Gy and the median dose was 50Gy. There were 40 patients with normal thyroid function(NC group) and 36 patients with subclinical hypothyroidism(SHT group). The SHT patients received LT 4 treatment from 25 μg/day with the does gyadually increased till thyrotropin(TSH) was normal. The serum levels of TSH, free thyroxine (FT 4 ), free triiodothyronine (FT 3 ), total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) in NC group and SHT group was measured and compared before and after LT4 treatment. Results: The serum levels of TSH, FT 3 , FT 4 , TC, TG, HDL-C, LDL-C in pre-and post-treatment SHT group and NC group were significantly different between those in the pre-and post-treatment SHT group was measured aha compared, and pre-treatment SHT group and NC group except HDL-C (P<0.001 or 0.05). Conclusions: Radiotherapy on NPC patients can induce SHT, and LT4 treatment for SHT patients can ameliorates the function of thyroid and metabolism of serum lipid. (authors)

    The aim of this study was to test the hypothesis that omega-3 fatty acids have an effect on serum lipids and inflammation markers in chronic hemodialysis (HD) patients. The study followed a single-blind, randomized, crossover design. The study was conducted at the Hemodialysis Unit of the Laikon General Hospital in Athens, Greece. A total of 25 chronic HD patients were included in the study (16 men, 9 women, age: 51 ± 15 years). Patients were randomly assigned to one of the following 2 intervention groups: omega-3 fatty acids plus α-tocopherol (920 mg eicosapentaenoic Acid (EPA), 760 mg docosahexaenoic acid (DHA), 8 mg α-tocopherol in total per day) or α-tocopherol supplement (100 mg/week resulting in 14.2 mg/day) alone for 4 weeks. After a washout period of 4 weeks, the 2 groups were crossed. Medical history data were collected and anthropometric and nutritional intake evaluation was performed at the beginning and at the end of both interventions. Hematological and biochemical parameters as well as C-reactive protein levels were measured. No statistically significant results were recorded in the lipidemic profiles of the participants between baseline and the 2 interventions. C-reactive protein levels also did not change significantly between the 2 interventions (5.54 ± 3.33 to 6.70 ± 5.01 mg/L [P = .19] with vitamin E vs. 7.13 ± 5.04 to 6.87 ± 5.24 [P = .78] with omega-3, P overall = .53). The results of this study do not provide support for the positive effects of omega-3 fatty acid supplementation in HD patients. Copyright © 2011 National Kidney Foundation, Inc.

    Safety assessment for genetically-engineered crop plants includes assessment for allergic responses. To facilitate this assessment, serum banks should contain well-characterised sera from patients with confirmed food allergies. A serum is defined as well-characterised if it is taken from a patient who has a convincing history of allergic responses to a known allergen or an allergen-containing food, a positive skin prick test (or elevated IgE response), and a positive response in a clinical food challenge.

    We evaluated genetic variants of apolipoprotein E (APOE HhaI) and their association with serum lipids in colorectal cancer (CRC), together with eating habits and personal history. Eight-seven adults with CRC and 73 controls were studied. APOE*2 (rs7412) and APOE*4 (rs429358) were identified by polymerase chain reaction-restriction fragment length polymorphism. APOE gene polymorphisms were similar in both groups, but the epsilon4/epsilon4 genotype (6%) was present only in controls. The patients had reduced levels (mean +/- SD) of total cholesterol and low-density lipoprotein cholesterol fraction (180.4 +/- 49.5 and 116.1 +/- 43.1 mg/dL, respectively) compared to controls (204.2 +/- 55.6, P = 0.135 and 134.7 +/- 50.8 mg/dL; P = 0.330, respectively) indicating that they were not statistically significant after the Bonferroni correction. The APOE*4 allele was associated with lower levels of total cholesterol, low- and high-density lipoprotein cholesterol fraction and increased levels of very low-density lipoprotein cholesterol fraction and triglycerides only among patients (P = 0.014). There was a positive correlation between the altered lipid profile and increased body mass indexes in both groups (P hypertension and overweight was observed in controls (P < 0.002). In conclusion, the presence of the epsilon4/epsilon4 genotype only in controls may be due to a protective effect against CRC. Lower lipid profile values among patients, even those on lipid-rich diets associated with the APOE*4 allele, suggest alterations in the lipid synthesis and metabolism pathways in CRC.

    Full Text Available We evaluated genetic variants of apolipoprotein E (APOE HhaI and their association with serum lipids in colorectal cancer (CRC, together with eating habits and personal history. Eight-seven adults with CRC and 73 controls were studied. APOE*2 (rs7412 and APOE*4 (rs429358 were identified by polymerase chain reaction-restriction fragment length polymorphism. APOE gene polymorphisms were similar in both groups, but the ε4/ε4 genotype (6% was present only in controls. The patients had reduced levels (mean ± SD of total cholesterol and low-density lipoprotein cholesterol fraction (180.4 ± 49.5 and 116.1 ± 43.1 mg/dL, respectively compared to controls (204.2 ± 55.6, P = 0.135 and 134.7 ± 50.8 mg/dL; P = 0.330, respectively indicating that they were not statistically significant after the Bonferroni correction.

There was a positive correlation between the altered lipid profile and increased body mass indexes in both groups (P < 0.010. Moreover, a higher rate of hypertension and overweight was observed in controls (P < 0.002. In conclusion, the presence of the ε4/ε4 genotype only in controls may be due to a protective effect against CRC. Lower lipid profile values among patients, even those on lipid-rich diets associated with the APOE*4 allele, suggest alterations in the lipid synthesis and metabolism pathways in CRC.

    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.

    The effects of a daily fish oil supplement rich in eicosapentaenoic acid were studied in 11 stable continuous ambulatory peritoneal dialysis (CAPD) patients. Serum lipids, platelet aggregation studies, and template bleeding times were determined before and after 4 weeks of fish oil treatment. The lipid studies were repeated approximately 20 weeks after stopping fish oil supplement. At the end of the treatment period, serum triglycerides (mean +/- SEM) decreased from 297 +/- 42 to 211 +/- 29 mg/dL (P less than .01), high density lipoprotein (HDL) cholesterol fell from 45 +/- 3 to 41 +/- 3 mg/dL (P less than .05), and low density lipoprotein (LDL) cholesterol increased from 172 +/- 16 to 208 +/- 19 mg/dL (P less than .05). After discontinuing the fish oil supplement, the triglycerides increased to 278 +/- 39 mg/dL, which was no different than the value before fish oil treatment. No significant changes occurred in template bleeding time (TBT), platelet count, hematocrit, or platelet aggregation response. Clinically important uremic bleeding was not apparent. We conclude that in CAPD patients a fish oil supplement favorably effects hypertriglyceridemia and can be ingested without promoting uremic bleeding. The likely beneficial impact on atherogenesis resulting from the lowering of the triglycerides may, however, be counteracted by concomitant changes in HDL- and LDL-cholesterol.

    More than 25 % of children with epilepsy develop refractory seizures unresponsive to both old and new generation anticonvulsants. Since such seizures have a serious negative impact on the quality of life, other treatment options are considered. The ketogenic diet is a well-known treatment for managing refractory seizures, although its mechanism of action is unknown. Studies have shown that this diet is as good as, or better than, any of the newer medications in reducing seizure frequency. However, concerns about adverse effects have been raised. We conducted an open label trial to show the effects of this diet on serum lipid profile. Thirty-three children with refractory epilepsy were treated with the ketogenic diet and were followed for 6 months. Their serum lipid profile was assessed at baseline, and at 3 and 6 months after initiating the diet. Seizure frequency was reduced in 63 % of children (no seizures in 2/33 and reduced >50 % in 19/33). However, after 6 months of administering the diet, median triglyceride was significantly increased (from 84 to 180 mg/dl, P ketogenic diet in children with refractory seizures is effective in seizure reduction, but leads to development of hypercholesterolemia and hypertriglyceridemia.

    Objective: To study the variations and influencing factors of serum triglycerides and cholesterol levels during pregnancy and postpartum. Methods: A retrospective study was performed among 5 020 healthy singleton (95.10%, 4 774/5 020) and twin (4.90%, 246/5 020) women who had delivery in Women's Hospital, Zhejiang University School of Medicine from January 2011 to December 2016. Serum triglycerides and cholesterol levels during pregnancy and postpartum of all the cases were collected. Both singleton and twin pregnant women were divided into advanced age and appropriate age groups, and then data of serum sample were assigned to 3 groups according to the gestation weeks, which were second trimester pregnancy (24-28 gestation weeks) , third trimester pregnancy (32-41 gestation weeks) and postpartum (within 72 hours after delivery) . The serum triglycerides and cholesterol levels in each groups were compared. Results: (1) Serum triglycerides and cholesterol levels during the second trimester pregnancy, third trimester pregnancy and postpartum were higher than levels of non-pregnancy in both singleton and twin groups (all Ppregnancy group were higher than those of second trimester pregnancy group in both advanced age and appropriate aged women regardless singleton or twin pregnancy (all Ppregnancy were as follows: in appropriate aged singleton group, the triglycerides levels were 1.07-4.13 and 1.52-7.21 mmol/L, and the cholesterol levels were 2.77-12.11 and 4.44-9.36 mmol/L. In advanced aged singleton group, the triglycerides levels were 1.28-4.61 and 1.70-7.80 mmol/L, and the cholesterol levels were 4.35-8.40 and 4.46-9.35 mmol/L; in appropriate aged twin group, the triglycerides levels were 1.39-7.16 and 1.90-9.29 mmol/L, and the cholesterol levels were 4.99-12.16 and 4.52-10.07 mmol/L; in advanced aged twin group, the triglycerides levels were 1.61-5.32 and 1.94-9.29 mmol/L, and the cholesterol levels were 5.24-8.10 and 4.53-8.86 mmol/L.

    The potential value of a biobank depends on the quality of the samples, i.e. how well they reflect the biological or biochemical state of the donors at the time of sampling. Documentation of sample quality has become a particularly important issue for researchers and users of biobank studies. The aim of this study was to investigate the long-term stability of selected components: cholesterol, high density cholesterol (HDLC), low density cholesterol (LDLC), apolipoprotein A1 (apo-A1), apolipoprotein B (apo B), follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), thyroid stimulating hormone (TSH) and free thyroxin (FT4). Samples, stored at -25°C, from 520 men aged 40-49 years at blood sampling distributed in equally sized groups (n=130) according to length of storage, 0, 4, 17 and 29 years, respectively, were used in a cross sectional design. The freshly collected serum samples were used as a reference group to calculate storage related changes. The differences between fresh samples and samples stored for 29 years were substantial for apo-A1 (+12%), apo-B (+22.3%), HDLC (-69.2%), LDLC (+31.3%), and PRL (-33.5%), while total cholesterol, FSH, LH, TSH and FT4 did not show any significant difference. The study showed large differences in serum level of the selected components. The lipids and apolipoproteins were all changed except for total cholesterol. Most hormones investigated (FSH, LH, TSH and FT4) proved to be stable after 29 years of storage while PRL showed sign of degradation. The observed differences are probably due to long-term storage effects and/or external factors (i.e. diet and smoking). Copyright © 2014 The Canadian Society of Clinical Chemists.

    Ketogenic diet (KD) is one of the most effective therapies for intractable epilepsy. Olive oil is rich in monounsaturated fatty acids and antioxidant molecules and has some beneficial effects on lipid profile, inflammation and oxidant status. The aim of this study was to evaluate the serum lipid levels of children who were receiving olive oil-based KD for intractable seizures at least 1 year. 121 patients (mean age 7.45 ± 4.21 years, 57 girls) were enrolled. At baseline and post-treatment 1, 3, 6, and 12 months body mass index-SDS, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol and triglyceride levels were measured. Repeated measure ANOVA with post hoc Bonferroni correction was used for data analysis. The mean duration of KD was 15.4 ± 4.1 months. Mean total cholesterol, LDL-cholesterol and triglyceride levels were significantly higher at 1st, 3rd, 6th and 12th months of the KD treatment, compared to pre-treatment levels (p = 0.001), but showed no difference among during-treatment measurements. Mean body mass index-SDS and HDL-cholesterol levels were not different among the baseline and follow-up time points (p = 0.113 and p = 0.067, respectively). No child in this study discontinued the KD because of dyslipidemia. Even if rich in olive oil, high-fat KD causes significant increase in LDL-cholesterol and triglyceride levels. More studies are needed to determine the effect of KD on serum lipids in children using different fat sources in the diet.

    To evaluate the effects of eslicarbazepine acetate (ESL) on lipid metabolism and to determine whether reduced statin exposure during ESL therapy has clinical consequences. We conducted a post-hoc analysis of pooled data for serum lipids (laboratory values) from three phase III, multicenter, randomized, double-blind, placebo-controlled trials of adjunctive ESL therapy (400, 800, or 1200 mg once daily) in patients with treatment-refractory partial-onset seizures. Changes from baseline in serum lipid levels were analyzed according to use of statins and/or enzyme-inducing antiepileptic drugs (EIAEDs) during the baseline period. In total, 426 and 1021 placebo- and ESL-treated patients, respectively, were included in the analysis. With regard to the changes from baseline in serum concentrations, there were statistically significant differences between the placebo and ESL 1200 mg QD groups, for both total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C), but the effect sizes were small (+4.1 mg/dL and +1.8 mg/dL, respectively). A small but significant difference in low-density lipoprotein cholesterol (LDL-C; -5.0 mg/dL) was observed between the ESL 400 mg QD group and the placebo group. In patients not taking a concomitant EIAED, there were no changes with ESL 400 mg QD, but modest and statistically significant increases in cholesterol fractions (TC, LDL-C and HDL-C) with ESL 800 mg QD (ESL 1200 mg QD (ESL had no consistent effect on lipids in patients taking a concomitant EIAED. In patients taking statins during baseline, there were no clinically relevant changes in serum lipids during use of ESL, although the subgroups were small. These results suggest that ESL does not appear to have clinically significant effects on serum lipids, nor does the pharmacokinetic interaction between ESL and statins have an impact on serum lipid concentrations.

    To assess the serum lipids and lipoprotein cholesterol in patients with complicated type 2 Diabetes Mellitus (DM): Hypertensive diabetics and diabetic nephropathy. This is a cross-sectional study. A total of 52 type 2 DM patients and 20 healthy controls were studied. The patients' population consisted of 23 normotensive diabetics, 16 hypertensive diabetics and 13 patients with diabetic nephropathy. The serum total cholesterol, HDL-cholesterol and triglycerides were assayed in patients and controls, using standardized assay methods. The mean serum total cholesterol was higher in patients than controls. The normotensive diabetic patients had the lowest total cholesterol among the patients groups 4.01+-0.82 mmol/L compared to the hypertensive diabetics 6.01+-0.93 mmol/L and the diabetic nephropathy patients 6.90+-1.20 mmol/L, (P <0.0001). The prevalence of dyslipidaemia in the patients was between 25% - 69%, lowest in the normotensive diabetics and highest in the diabetic nephropathy patients. We hope that these findings will draw specific attention to the management of dyslipidaemia in patients with complicated type 2 DM especially diabetic nephropathy and hypertensive diabetics.

    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)

    Nickel exposure greatly depletes intracellular ascorbate and alters ascorbate-cholesterol metabolism. We studied the effect of the simultaneous oral treatment with L-ascorbic acid (50 mg/100 g body weight (BW) and nickel sulfate (2.0 mg/100 g BW, i.p) on nickelinduced changes in serum lipid profiles and liver histopathology. Nickel-treated rats showed a significant increase in serum low-density lipoprotein-cholesterol, total cholesterol, triglycerides, and a significant decrease in serum high-density lipoprotein-cholesterol. In the liver, nickel sulfate caused a loss of normal architecture, fatty changes, extensive vacuolization in hepatocytes, eccentric nuclei, and Kupffer cell hypertrophy. Simultaneous administration of L-ascorbic acid with nickel sulfate improved both the lipid profile and liver impairments when compared with rats receiving nickel sulfate only. The results indicate that L-ascorbic acid is beneficial in preventing nickel-induced lipid alterations and hepatocellular damage.

    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

    For a better understanding of the relationship between lipid peroxide (LPO) and vascular diseases, the author determined LPO levels and lipid contents of serum lipoprotein fractions of diabetics with angiopathy. The LPO level in high density lipoprotein (HDL) fraction of diabetic serum was significantly higher than that of normal serum whereas no significant increase was observed in the levels of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) fractions of diabetic serum. As to the ratios of LPO to total lipids in these lipoprotein fractions, it was found that the ratio in HDL fraction of the diabetics was markedly higher than that of the normals. These results suggest that the increase in LPO levels in the sera of diabetic patiens is due to that in HDL fraction. To study further this problem, the author employed 60 Co-irradiated rabbit as a model, since it was already reported that radiation affects lipid metabolism and LPO formation, and that it induces the development of atherosclerosis. Upon irradiation with 60 Co ranging from 100R to 700R, serum LPO level of rabbit was significantly increased. Although elevation of LPO level was found in each serum lipoprotein fraction of VLDL, LDL and HDL, LPO level per lipid content was significantly increased only in HDL fraction. In the irradiated rabbit, significant elevation of the level of LPO was also observed in the liver, while no significant increase was found in the kidney and spleen. These results indicate that high level of LPO observed in the serum of irradiated rabbit would be the reflection of the increased LPO in the liver. (J.P.N.)

    Conspicuous facial pores are one type of serious aesthetic defects for many women. However, the mechanism(s) that underlie the conspicuousness of facial pores remains unclear. We previously characterized the epidermal architecture around facial pores that correlates with the appearance of those pores in various ethnic groups including Japanese. The goal of this study was to evaluate the possible relationships between facial pore size, the severity of impairment of epidermal architecture around facial pores and sebum output levels to investigate the possible role of IGF-1 in the pathogenesis of conspicuous facial pores. The subjects consisted of 38 healthy Japanese women (aged 22-41 years). IGF-1 was measured using immunoradiometric assay. Surface replicas were collected to compare pore sizes of cheek skin and horizontal cross-section images of cheek skin were obtained non-invasively from the same subjects using in vivo confocal laser scanning microscopy and the severity of impairment of epidermal architecture around facial pores was determined. The skin surface lipids of each subject were collected from their cheeks and lipid classes were determined using gas chromatography/flame ionization detection. The serum level of IGF-1 correlated significantly with total pore area (R = 0.36, P facial pores (R = 0.43, P pore area (R = 0.32, P facial skin characteristics including facial pore size and with the severity of impairment of epidermal architecture around facial pores. © 2010 The Authors.

    Full Text Available Twenty-four critically ill patients due to generalized purulent peritonitis, pancreatonecrosis, thermal skin injuries, and severe poisoning by acetic acid were examined. The general regularities of the effect of high serum iron concentrations on the health status of patients, on the activity of antioxidative enzymes, and on the initiation of lipid peroxidation (LPO processes, as supported by the values of Fe2+-induced chemiluminescence, were revealed. In critically ill patients, iron metabolism occurs with the overload of a transport protein, such as transferrin, which is caused by intravascular hemolysis and hemoglobin metabolism to ionized iron. The overload of proteins responsible for iron transport leads to the tissue accumulation of free (ferrous and ferric iron that is actively involved in the processes of LPO initiation with excess synthesis of cytotoxic radicals, which in turn accounts for the severity of endotoxicosis.

    Full Text Available Aim: Diabetic retinopathy (DR is the most common preventable cause of blindness where early detection and treatment can be sight-saving. Search for biomarkers of the disease has been relentless. We aimed to determine whether lipoproteins apolipoproteins A1 and B1 (Apo-A1 and Apo-B1 have stronger associations with DR in contrast to conventionally measured low-density lipoprotein (LDL and high-density lipoprotein cholesterol levels. Materials and Methods: We performed a cross-sectional study and studied 117 patients. Serum lipid profile was assessed by autoanalyzer. Serum Apo-A1 and Apo-B were measured using immunoturbidimetric kit on an autoanalyzer. Apo-B/A1 ratio was calculated. Retinopathy was graded from the digital retinal photographs, taken with nonmydriatic auto fundus camera and classified according to International Clinical DR Disease Severity Scale. Results: Mean Apo-A1 for mild, moderate, severe retinopathy, and proliferative DR (PDR shows a significant negative correlation (P = 0.001 with severity of retinopathy. Mean Apo-B for mild, moderate, severe, PDR displayed a significant positive correlation with severity of retinopathy (P = 0.001. Mean Apo-B/A1 for mild, moderate, severe, PDR showed highly significant positive correlation with severity of retinopathy (P < 0.001. In contrast, mean LDL for mild, moderate, severe, PDR showed insignificant association with severity of DR (P = 0.081. Conclusion: Apo-A1 and Apo-B have a stronger association with the development of DR than traditional lipids and can thus facilitate early detection and treatment of the disease.

The mutant allele is expressed widely, in all tissues, but the striatum and cortex are especially vulnerable to its effects. To more fully understand this tissue-specificity, early in the disease process, we asked whether the metabolic impact of the mutant CAG expanded allele in heterozygous B6.HdhQ111/+ mice would be common across tissues, or whether tissues would have tissue-specific responses and whether such changes may be affected by diet. Specifically, we cross-sectionally examined steady state metabolite concentrations from a range of tissues (plasma, brown adipose tissue, cerebellum, striatum, liver, white adipose tissue), using an established liquid chromatography-mass spectrometry pipeline, from cohorts of 8 month old mutant and wild-type littermate mice that were fed one of two different high-fat diets. The differential response to diet highlighted a proportion of metabolites in all tissues, ranging from 3% (7/219) in the striatum to 12% (25/212) in white adipose tissue. By contrast, the mutant CAG-expanded allele primarily affected brain metabolites, with 14% (30/219) of metabolites significantly altered, compared to wild-type, in striatum and 11% (25/224) in the cerebellum. In general, diet and the CAG-expanded allele both elicited metabolite changes that were predominantly tissue-specific and non-overlapping, with evidence for mutation-by-diet interaction in peripheral tissues most affected by diet. Machine-learning approaches highlighted the accumulation of diverse lipid species as the most genotype-predictive metabolite changes in the striatum. Validation experiments in cell culture demonstrated that lipid accumulation was also a defining feature of mutant HdhQ111 striatal progenitor cells. Thus, metabolite-level responses to the CAG expansion mutation in vivo were tissue specific and most evident

    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.

    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. © Georg Thieme Verlag KG Stuttgart · New York.

    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

    The effects of guar gum derived from the endosperm of Cyamopsis tetragonoloba (75% soluble fiber, 7.6% insoluble fiber, 2.16% crude protein, 0.78% total lipids, 0.54% ash and 9.55% moisture) on food intake, levels of blood serum cholesterol, triacylglycerols, glucose and LDL and HDL-cholesterol were studied. The effects of guar gum on indices of protein absorption and utilization were also investigated. Diets containing 0%, 10% and 20% (w/w) guar gum or 10% and 20% cellulose powder (reference) were fed to normal rats for 60 days. The rats fed the guar gum diets showed significantly (p Guar gum decreased blood serum glucose only during the first month of the experiment, and no changes in the indices of protein absorption and utilization were found. The guar gum caused a 10% increase in the small intestine length and a 25% retardation in the intestinal transit. The results of this research suggested that guar gum could potentially be effective in the treatment of hypercholesterolemia and obesity in humans.

    Objective: To investigate the prevalence of intrahepatic cholestasis during pregnancy and the relationship between levels of serum CG and blood lipids. Methods: Serum CG, blood lipid and liver function profile were examined in 2040 women with pregnancy during the second or third trimester. Among these pregnant women, 57 were diagnosed as with intrahepatic cholestasis. Blood lipids (TG, cholesterol, HDL, LDL) and ALP levels in 50 of the 57 pregnant women were studied and compared with those in 50 otherwise normal pregnant women as controls. Results: Serum CG levels were above normal range in 372 of the 2040 pregnant women (18.5%). Fifty seven of these 372 pregnant women were confirmed to be with intrahepatic cholestasis (2.8% of the 2040 pregnancies). The TG, cholesterol, LDL contents and ALP levels in the pregnant women with intrahepatic cholestasis were significantly higher (P 0.05) than those in controls. Conclusion: Intrahepatic cholestasis developed in a substantial proportion of pregnant women (2.8% in this study) and should be carefully monitored due to possible damage to the fetus. Serum CG was shown to be an early and sensitive marker for the diagnosis of intrahepatic cholestasis. Changes of blood lipid and ALP levels were related to disease status. (authors)

    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. 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. 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. 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 increase their consumption of green and other vegetables

    Objective: To investigate the clinical significance of changes of serum leptin (with RIA) and lipid (TG and TC) (with biochemistry) levels in patients with Graves' disease. Methods: Serum Leptin, TG and TC levels were determined in 29 patients with Graves' disease both before and after treatment as well as in 30 controls. Results: Before treatment, serum Leptin, TG and TC levels in the patients were significantly lower than those in the controls. After treatment, serum Leptin, TG and TC levels increased and were significantly higher than those before treatment and were not much different from those in controls. Conclusion: The changes of serum Leptin, TG and TC levels may be of value for outcome prediction in patients with Graves' disease. (authors)

    In our previous study, fish protein was proven to reduce serum lipids and body fat accumulation by skeletal muscle hypertrophy and enhancing basal energy expenditure in rats. In the present study, we examined the precise effects of fish protein intake on different skeletal muscle fiber types and metabolic gene expression of the muscle. Fish protein increased fast-twitch muscle weight, reduced liver triglycerides and serum glucose levels, compared with the casein diet after 6 or 8 weeks of feeding. Furthermore, fish protein upregulated the gene expressions of a fast-twitch muscle-type marker and a glucose transporter in the muscle. These results suggest that fish protein induces fast-muscle hypertrophy, and the enhancement of basal energy expenditure by muscle hypertrophy and the increase in muscle glucose uptake reduced liver lipids and serum glucose levels. The present results also imply that fish protein intake causes a slow-to-fast shift in muscle fiber type.

    People with type 2 diabetes are at an increased risk of hypertension, arteriosclerosis, heart disease, and stroke. Glucose intolerance (insulin resistance) is the main feature of type 2 diabetes. Obesity leads to insulin resistance, dyslipidemia, etc. The aim of this study was to assess the biochemical parameters and measures of obesity in type 2 diabetes mellitus (T2DM). A total of 2,273 males and 6,547 females previously healthy volunteers (aged 41-95 years old) were recruited by open invitation. The basic information, including age, sex, height, weight, body mass index (BMI), waistline, hipline, menstrual cycle, and medical history, was collected by questionnaire survey and physical examination. Serum lipid profile, liver transaminase, blood glucose, postprandial blood glucose, and hemoglobin A1c were obtained after 12 hours of fasting. According to our results, diabetic patients presented serum lipid abnormality. Elevated triglyceride (TG) levels (≥1.7 mmol/L) were noted in 19.69% of males and 20.40% of females, and reduced high-density lipoprotein cholesterol (HDL-C) levels (≤1.15 mmol/L) were noted in 21.96% of males and 15.74% of females. The combination of elevated TG and reduced HDL-C was the most prevalent of the combined lipid abnormalities. In contrast, no differences were observed in the levels of low-density lipoprotein cholesterol and total cholesterol. Moreover, there were statistically significant differences in the levels of BMI and waistline between T2DM and non-T2DM participants. After adjustment for BMI, logistic regression analysis revealed that the subjects with BMI ≤20 kg/m(2) and >30 kg/m(2) had a significantly elevated hazard ratio of T2DM compared with participants having a BMI range of 20-30 kg/m(2) in both males and females. However, there was a significant difference between T2DM patients and non-T2DM patients in waistline (χ (2)=8.57, P<0.001) than in BMI parameter (χ (2)=6.29, P<0.001). The present study shows for the first

    Previous data suggest that myostatin has direct effects on the proliferation and differentiation of osteoprogenitor cells. The relationships between serum myostatin, body composition lipids and bone mineral density in postmenopausal women remain unclear. The aim of this study is to elucidate the relationships between serum myostatin, body composition, lipids and bone mineral density in central south Chinese postmenopausal women. A cross-sectional study was conducted in 175 healthy postmenopausal women, aged 51-75 years old. Bone mineral density (BMD) and body composition were measured by double energy X-ray absorptiometry (DXA). Serum myostatin, 25-dihydroxyvitamin D(25OH-D), parathyroid hormone (PTH), bone alkaline phosphatase (BAP) and carboxy-terminal telopeptide of type I collagen (CTX) were measured by enzyme-linked immunoabsorbent assay (ELISA). In contrast to the osteoporotic women, the women without osteoporosis had higher BMI, fat mass and lean mass (Pmyostatin after adjusted by age. BMD at each site was positively correlated with age at menopause, fat mass and lean mass, and also negatively correlated with age and serum BAP. Serum myostatin was positively correlated with tryglicerides, not correlated with either body composition or BMD at each site. Our data indicated that serum myostatin concentration did not correlate with muscle and bone mass. Further studies are needed to demonstrate the role of myostatin in regulating the bone metabolism.

    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 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: 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.

    To determine decision limits for total cholesterol, LDL-cholesterol, non-HDL cholesterol, HDL-cholesterol, and triglycerides in healthy children and adolescents from Cuiabá, Brazil. This was a cross-sectional study of 1866 healthy children and adolescents randomly selected from daycare centers and public schools in Cuiabá. The desirable levels of serum lipids were defined using the classic criteria, i.e., total cholesterol, LDL-cholesterol, non-HDL cholesterol, and triglycerides levels below the P75 percentile, and HDL-c above the P10 percentile. For CT, P75 was: 160mg/dL for the age range of 1 to <3 years, 170mg/dL for ≥3 to <9 years, and 176mg/dL for ≥9 to <13 years. For non-HDL cholesterol, it was 122mg/dL for the age range of 1 to <13 years. For LDL-c, it was 104mg/dL at the age range of 1 to <9 years and 106mg/dL from ≥9 to <13 years. For TG, it was 127mg/dL from 1 to <2 years; 98mg/dL from ≥2 to <6 years; and 92mg/dL from ≥6 to <13 years. As for HDL-cholesterol, P10 was 24mg/dL, 28mg/dL, 32mg/dL, and 36mg/dL, for the age ranges of 1 to <2 years, ≥2 to <3 years, ≥3 to <4 years, and ≥4 to <13 years, respectively. The decision limits for the serum lipid levels defined in this study differed from those observed in the current Brazilian and North-American guidelines, especially because it differentiates between the age ranges. Using these decision limits in clinical practice will certainly contribute to improve the diagnostic accuracy for dyslipidemia in this population group.

    There is some evidence that low lipid levels cause suicide in depressed patients. The purpose of this study was to identify whether low serum lipid levels are associated with suicide ideation or are correlated with central serotonin function. Auditory processing for the loudness dependence of auditory evoked potentials (LDAEP) was measured in 73 outpatients with major depressive disorder. The Hamilton Depression Rating Scale (HAMD) and the Beck Depression Inventory (BDI) were administered on the same day as measurement of the LDAEP. In addition, serum levels of total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) levels were measured. All subjects had received antidepressant monotherapy. The depressed subjects were divided into those with and without suicide ideation according to the score for HAMD item 3 or BDI item 9. TG levels differed significantly between the two groups, whereas body mass index (BMI), total cholesterol, LDL, HDL, and LDAEP did not. The scores for HAMD item 3 and BDI item 9 were negatively correlated with TG levels (p=0.045 and 0.026, respectively). The LDAEP was negatively correlated with TG levels (p=0.012). Although there was tendency toward a negative correlation between the LDAEP and serum LDL, it did not reach statistical significance (p=0.068). The cross-sectional design of this study means that baseline serum lipid levels were not measured. The findings of this study revealed a relationship between TG and suicide ideation that is independent of both BMI and body weight. Furthermore, serum lipid levels were associated with central serotonergic activity, as assessed using the LDAEP. Copyright © 2014 Elsevier B.V. All rights reserved.

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.

    The ban or severe restriction on the use of antibiotics in poultry feeds to promote growth has led to considerable interest to find alternative approaches. Probiotics have been considered as such alternatives. In the present study, the effects of a Lactobacillus mixture composed from three previously isolated Lactobacillus salivarius strains (CI1, CI2 and CI3) from chicken intestines on performance, intestinal health status and serum lipids of broiler chickens has been evaluated. Supplementation of the mixture at a concentration of 0.5 or 1 g kg-1 of diet to broilers for 42 days improved body weight, body weight gain and FCR, reduced total cholesterol, LDL-cholesterol and triglycerides, increased populations of beneficial bacteria such as lactobacilli and bifidobacteria, decreased harmful bacteria such as E. coli and total aerobes, reduced harmful cecal bacterial enzymes such as β-glucosidase and β-glucuronidase, and improved intestinal histomorphology of broilers. Because of its remarkable efficacy on broiler chickens, the L. salivarius mixture could be considered as a good potential probiotic for chickens, and its benefits should be further evaluated on a commercial scale.

    Full Text Available Background and aims: We designed this study to assess the effect of Ramadan fasting on serum lipid profile among type 2 diabetic patients. Material and Methods: The study was carried out in July 2014 (Ramadan 1421. The total duration of fasting was 17 hours a day. The investigation involved 80 patients. The mean age of the patients was 56± 8 years. The dietary survey lasting three days was recorded. The anthropometric and the biochemical parameters were measured in all subjects before (T1 and during (T2 the fasting month of Ramadan and results were compared using student t-test. Results: There was a significant decrease in high density lipoprotein cholesterol (HDL-c levels during T2 (0.35±0,08 g/L compared to T1 (0.38±0,11 g/L. Apolipoprotein A1 (Apo A1 decreased significantly during fasting compared to pre-fasting days while apo B increased during T2 (p˂0.05. The dietary fat consumption increased during Ramadan; especially for the saturated one (p<0.05. Conclusion: The present study suggests that fasting month of Ramadan could be beneficial for some patients with type 2 diabetes who are well controlled and balanced. However, some of them may be at risk of cardiovascular complications in which dyslipidemia can be the leading cause.

    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.

    objective Nonalcoholic fatty liver disease (NAFLD) and its association with insulin resistance are increasingly recognized as major health burdens. The main objectives of this study were to assess the relation between liver lipid content and serum lipids, markers of liver function and inflammation in healthy overweight subjects, and to determine whether caloric restriction (CR) (which improves insulin resistance) reduces liver lipids in association with these same measures. Methods and Procedures Forty-six white and black overweight men and women (BMI = 24.7-31.3 kg/m2) were randomized to “control (CO)” = 100% energy requirements; “CR” = 25%; “caloric restriction and increased structured exercise (CR+EX)”= 12.5% CR + 12.5% increase in energy expenditure through exercise; or “low-calorie diet (LCD)” = 15% weight loss by liquid diet followed by weight-maintenance, for 6 months. Liver lipid content was assessed by magnetic resonance spectroscopy (MRS) and computed tomography (CT). Lipid concentrations, markers of liver function (alanine aminotransferase (ALT), alkaline phosphatase (ALK)), and whole-body inflammation (tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP)) were measured in fasting blood. Results At baseline, increased liver lipid content (by MRS) correlated (P triglyceride (r = 0.52), ALT (r = 0.42), and hsCRP (r = 0.33) concentrations after adjusting for sex, race, and alcohol consumption. With CR, liver lipid content was significantly lowered by CR, CR+EX, and LCD (detected by MRS only). The reduction in liver lipid content, however, was not significantly correlated with the reduction in triglycerides (r = 0.26; P = 0.11) or with the changes in ALT, high-density lipoprotein (HDL)-cholesterol, or markers of whole-body inflammation. Discussion CR may be beneficial for reducing liver lipid and lowering triglycerides in overweight subjects without known NAFLD. PMID:18421281

    The use of dried blood spots (DBS) has many advantages over traditional plasma and serum samples such as smaller blood volume required, storage at room temperature, and ability for sampling in remote locations. However, understanding the robustness of different analytes in DBS samples is essential, especially in older samples collected for longitudinal studies. Here we analyzed DBS samples collected in 2000-2001 and stored at room temperature and compared them to matched serum samples stored at -80°C to determine if they could be effectively used as specific time points in a longitudinal study following metabolic disease. Four hundred small molecules were identified in both the serum and DBS samples using gas chromatograph-mass spectrometry (GC-MS), liquid chromatography-MS (LC-MS) and LC-ion mobility spectrometry-MS (LC-IMS-MS). The identified polar metabolites overlapped well between the sample types, though only one statistically significant polar metabolite in a case-control study was conserved, indicating degradation occurs in the DBS samples affecting quantitation. Differences in the lipid identifications indicated that some oxidation occurs in the DBS samples. However, thirty-six statistically significant lipids correlated in both sample types indicating that lipid quantitation was more stable across the sample types.

    Full Text Available BACKGROUND: The detrimental effects of partially hydrogenated vegetable oils (PHVOs on apolipoproteins have been reported from several parts of the world. However, little data is available in this regard from the understudied region of the Middle East. The present study therefore tried to evaluate the association between type of vegetable oils and serum lipids and apolipoprotein levels among Iranians. METHODS: In this cross-sectional study, data from 1772 people (795 men and 977 women aged 19-81 years, who were selected with multistage cluster random sampling method from three cities of Isfahan, Najaf Abad and Arak in "Isfahan Healthy Heart Program" (IHHP, was used. To assess participants' usual dietary intakes, a validated food frequency questionnaire was used. Hydrogenated vegetable oil (commonly consumed for cooking in Iran and margarine were considered as the category of PHVOs. Soy, sunflower, corn, olive and canola oils were considered as non-HVOs. After an overnight fasting, serum cholesterol (total, low density lipoprotein (LDL and high density lipoprotein (HDL cholesterol and triglyceride as well as apolipoproteins A and B were measured using standard methods. RESULTS: Participants with the highest intakes of non-HVOs and PHVOs were younger and had lower weight than those with lowest intakes. High consumption of non-HVOs and PHVOs was associated with lower intakes of energy, carbohydrate, dietary fiber, and higher intakes of fruits, vegetables, meat, milk and grains. No overall significant differences were found in serum lipids and apolipoprotein levels across the quartiles of non-HVOs and PHVOs after controlling for potential confounding. CONCLUSION: We did not find any significant associations between hydrogenated or non-hydrogenated vegetable oil and serum lipid and apolipoprotein levels. Thus, further studies are needed in this region to explore this association. Keywords: Vegetable Oils, Cardiovascular Risk Factors, Lipids

    Full Text Available Introduction. Coronary artery disease (CAD is one of the most prevalent disease in human population that has high prevalence and mortality in lsfahan (Iran. As positive family history and changes in serum lipids and lipoproteins are risk factors of these diseases, and also studies have showed the relationship between serum vitamin D and CAD, we studied serum level of lipids, lipoproteins and vitamin D in high risk children compared with control group, and the relation between serum vitamin D and other factors. Methods. This case-control study was done on 44 subjects (25 boys, 19 girls aged 2-18 years old with positive CAD family history as case group and also 44 persons with negative CAD family history as control group with the same age groups. The subjects were selected by convenience sampling method. Children who consumed antiepilepthic drugs as phenytoin or phenobarbital and those who had positive family histroy for renal stone were excluded for variable vitamin D levels due to drug interaction and genetic susceptibility, respectively. All subjects were invited to Isfahan Cardiovascular Research Center. Using a questionnaire, information on personal characteristics, CVD family history and ... were obtained. A fasting (12-14 hr blood sample was drawn from each one. Serum APOA1, APO B100 and vitamin Dwere measured by radioimmunoassay and serum lipids by ELAN 2000 autoanalyzer. Statistical analysis was done by SPSS. The level of serum APOA1, APO B100 and vitamin D were compared between two groups by independent t test and the relation of the mentioned apolipoproteins with vitamin D was studied using multiple linear regression. Results. Serum vitamin D was significantly lower in case group (P < 0.045. Among studied factors, only triglyceride was significantly higher in control group (P < 0.0001 and also no significant relaitonship was observed between serum APO A1, APO B100 and vitamin D. Sex comparision in case group showed those mean levels

    Full Text Available Despite the significant progresses made in the reduction of mortality due to cardiovascular diseases, they are still the primary cause of death in many countries and hyperlipidemia is an important causal agent of cardiovascular diseases. Probiotics are food supplements containing live microbes which balance the flora of the digestive system and produce positive effects in the host body. L.acidophilus is a beneficial bacterium used in the production of probiotic products .The aim of this study is to evaluate the effects of consumption of milk containing L.acidophilus on serum lipid trends of rats fed high lipid diet. This is an experimental study in which 30 male albino Wistar rats with a body weight of 200±15 gr. were randomly allocated to two groups of treatment and control each containing 15 rats which were adapted to a high lipid diet (11.74% and water containing 25% milk within a week. Rats in both groups received high lipid diet and water containing 25% milk for 60 days with the exception that rats in the treatment group received water containing L. acidophilus at a level of 109 CFU/rat/day throughout the experiment. Independent t-test revealed that at a level of α= 0.05, mean levels of total cholesterol and LDL-C of rats in the treatment group was significantly lower than the control group (p

    Spleen removal may be recommended during organ transplantation in ABO-incompatible recipients as well as for hypoperfusion of the grafted liver, besides conventional surgical indications, but elevation of serum lipids has been observed in certain contexts. Aiming to analyze the influence of two dietary regimens on lipid profile, an experimental study was conducted. Male Wistar rats (n = 86, 333.0 +/- 32.2 g) were divided in four groups: group 1: controls; group 2: sham operation; group 3: total splenectomy; group 4: subtotal splenectomy with upper pole preservation; subgroups A (cholesterol reducing chow) and B (cholesterol-rich mixture) were established, and diet was given during 90 days. Total cholesterol (Tchol), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and triglycerides were documented. After total splenectomy, hyperlipidemia ensued with cholesterol-reducing chow. Tchol, LDL, VLDL, triglycerides, and HDL changed from 56.4 +/- 9.2, 24.6 +/- 4.7, 9.7 +/- 2.2, 48.6 +/- 11.1, and 22.4 +/- 4.3 mg/dL to 66.9 +/- 11.4, 29.9 +/- 5.9, 10.9 +/- 2.3, 54.3 +/- 11.4, and 26.1 +/- 5.1 mg/dL, respectively. Upper pole preservation inhibited abnormalities of Tchol, HDL, VLDL, and triglycerides, and LDL decreased (23.6 +/- 4.9 vs. 22.1 +/- 5.1, P = 0.002). Higher concentrations were triggered by splenectomy and cholesterol-enriched diet (Tchol 59.4 +/- 10.1 vs. 83.9 +/- 14.3 mg/dL, P = 0.000), and upper-pole preservation diminished without abolishing hyperlipidemia (Tchol 55.9 +/- 10.0 vs. 62.3 +/- 7.8, P = 0.002). After splenectomy, hyperlipidemia occurred with both diets. Preservation of the upper pole tended to correct dyslipidemia in modality A and to attenuate it in subgroup B. (c) 2008 Wiley-Liss, Inc.

    Certain cancer patients are subjected to varying levels of intermittent radiation delivered in certain cases as whole body exposure. Effective control of many haematological complications built up during radiation treatment would necessarily contribute to up-grading of cancer radiotherapy. In the present study, the effect of either shot or intermittent whole body gamma irradiation at cumulative dose levels up to 6 and 10 Gy, have been evaluated on the levels of total lipids and lipid fractions in blood serum of male albino rats. The pharmacological role of serotonin and its potential radioprotective capacity have been assessed on the serum lipid pattern. The results indicated generally significant increases in the levels of blood lipid fractions especially HDL-cholesterol. On the other hand, the level of LDL-cholesterol recorded a significant decrease on the third day post either shot or cumulative dose levels at 6 or 10 Gy and also post 4 successive doses of serotonin administration. The only exceptions were recorded in the case of LDL-cholesterol post administration of single dose of serotonin and serotonin prior to shot dose levels of 6 or 10 Gy. 2 tabs

    To examine how serum lipids relates to specific cognitive ability domains between the men and women in Chinese middle to older age individuals. A complete lipid panel was obtained from 1444 individuals, ages 50-65, who also underwent a selection of cognitive tests. Participants were 584 men and 860 women from Linyi city, Shandong province. Multiple linear regression analyses examined serum lipids level as quadratic predictors of sex-specific measure of performance in different cognitive domains, which were adjusted for sociodemographic and lifestyle characteristics. In men, a significant quadratic effect of total cholesterol (TC) was identified for Digit Symbol (B = -0.081, P = 0.044) and also quadratic effect of low density lipoprotein-cholesterol (LDL-C) was identified for Trail Making Test B (B = -0.082, P = 0.045). Differently in women, there were significant quadratic associations between high density lipoprotein-cholesterol (HDL-C) and multiple neuropsychological tests. The nonlinear lipid-cognition associations differed between men and women and were specific to certain cognitive domains and might be of potential relevance for prevention and therapy of cognitive decline.

    Statin treatment and exercise training can improve lipid profile when administered separately. The efficacy of exercise and statin treatment combined, and its impact on myalgia and serum creatine kinase (CK) have not been completely addressed. The purpose of this study was to determine the effect of statin treatment and the addition of exercise training on lipid profile, including oxidized low-density lipoprotein (oxLDL), and levels of CK and alanine transaminase. Thirty-one hypercholesterolemic and physically inactive subjects were randomly assigned to rosuvastatin (R) or rosuvastatin/exercise (RE) group. A third group of physically active hypercholesterolemic subjects served as an active control group (AC). The R and RE groups received rosuvastatin treatment (10 mg/d) for 20 weeks. From week 10 to week 20, the RE group also participated in a combined endurance and resistive exercise training program (3 d/wk). Lipid profile was determined for all subjects at week 0 (Pre), week 10 (Mid), and week 20 (Post). The CK and alanine transaminase levels were measured at the same time points in the RE and R groups and 48 hours after the first and fifth exercise bout in the RE group. Each RE subject was formally queried about muscle fatigue, soreness, and stiffness before each training session. Total, LDL, and oxLDL cholesterol was lower in the RE and R groups at Mid and Post time points when compared with Pre. Oxidized LDL was lower in the RE group compared with the R group at the Post time point. When treatment groups (R and RE) were combined, high-density lipoprotein levels were increased and triglycerides decreased across time. Creatine kinase increased in the RE group 48 hours after the first exercise bout, but returned to baseline levels 48 hours after the fifth exercise bout. Rosuvastatin treatment decreased total, LDL, and oxLDL cholesterol. The addition of an exercise training program resulted in a further decrease in oxLDL. There was no abnormal sustained increase

    Full Text Available An experiment was conducted to study the effect of curcumin supplementation inexpose monochromatic light on serum lipid concentrations of sexually mature female magelang duck. One hundred and ninety two female magelang ducks were assigned into a completely randomized design with a 4×4 factorial arrangement and each experimental unit was repeated 3 times, each with 4 female magelang ducks. The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg/duck/day. The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue colors. The data were analyzed by two-way ANOVA. The result showed that serum concentrations of triglyceride, cholesterol, very low density lipoprotein (VLDL, and low density lipoprotein (LDL were lower (P<0.05 while high density lipoprotein (HDL were higher (P<0.05 in experimental ducks supplemented with a curcumin dose of 36 mg/duck/day in variety of monochromatic light colors compared to control experimental ducks without curcumin supplementation. The curcumin doses of 18 or 36 mg/duck/day within red, green, or blue light had the potential to modulate lipid metabolism, as indicated by the increased serum concentration of HDL and the decreased serum concentrations of triglyceride, cholesterol, VLDL, and LDL of the experimental female magelang ducks.

    Full Text Available Background & aim: Nowadays, Iranian lifestyles are changing, especially children may be effected by the increase of cardiovascular diseases. Studies have shown that different methods of exercise are the most important determinants of cardiovascular risk factors. The aim of this study was to survey the lipid profile, insulin resistance, and adiponectin levels following eight weeks of endurance, strength and combined training in inactive obese children. Methods: The present quasi-experimental field was conducted on Sixty obese male children (age: 8-12 years, BMI between 30-35 kg/m2 according to the World Health Organization who were purposefully selected and randomly divided into four experimental groups of 15 individuals including endurance exercise, resistance exercise, combined exercise and control. Exercise training programs were performed four times a week for eight weeks. To assess variable changes, ANOVA with repeated measurement and one way ANOVA was used. Results: Results showed that after three types of exercise training  the BMI, total chlostrol, TG, LDL, VLDL, and insulin resistance significantly decreased in experimental groups compared to control group (P=0.001. Serum HDL and adiponectin was significantly increased after different training in experimental groups in comparison to control group (P=0.001.  Conclusion: According to the findings, it is suggested that among three types of exercise applied in this study, particularly, endurance training is use to prevent and reduce the incidence of cardiovascular diseases and obesity-related disorders in inactive obese children. .

    Earlier studies in our group suggested that traditionally prepared buttermilk influences cholesterol metabolism. We therefore designed a study to evaluate whether traditionally prepared buttermilk lowers serum low-density lipoprotein cholesterol (LDL-C) and/or prevents the LDL-C raising effect of egg yolks. Mildly hypercholesterolemic subjects were randomly allocated to one of four diet groups consuming daily at lunch 80 ml skimmed milk with (n = 23) or without (n = 25) lutein-enriched egg yolk (28 g from 1.5 eggs providing 323 mg cholesterol) or traditionally prepared buttermilk with (n = 23) or without (n = 21) lutein-enriched egg yolk during a 12 week period. Fasting blood samples were taken to measure concentrations of serum lipids, (apo)lipoproteins, liver and kidney function markers, and plasma lutein, zeaxanthin and high-sensitive C-reactive protein (hsCRP). Egg yolk consumption significantly increased serum total cholesterol (total-C) (p = 0.035) and LDL-C concentrations (p = 0.022). Buttermilk did not change the effects of egg yolk on serum lipids and (apo)lipoproteins. There was a trend towards significant lower total-C (p = 0.077), but not LDL-C (p = 0.204) concentrations in the buttermilk groups. Plasma lutein and zeaxanthin concentrations increased significantly (p < 0.001) in the egg yolk groups. In mildly hypercholesterolemic subjects, daily consumption of traditionally prepared buttermilk for 12 weeks did not lower serum total-C or LDL-C concentrations, nor did it prevent the serum total-C and LDL-C raising effect of daily egg yolk consumption.

    Age-related macular degeneration (AMD) is a neurodegenerative disease that causes adult-onset blindness. There are 2 forms of this progressive disease: wet and dry. Currently there is no cure for AMD, but several treatment options have started to emerge making early detection critical for therapeutic success. Analysis of the eyes of Abca4(-/-)Rdh8(-/-) mice that display light-induced retinal degeneration indicates that 11-cis-retinal and docosahexaenoic acid (DHA) levels were significantly decreased as compared with the eyes of control dark-adapted C57BL/6J mice. In addition, exposure to intense light correlated with higher levels of prostaglandin G2 in the eyes of Abca4(-/-)Rdh8(-/-) mice. Intense light exposure also lowered DHA levels in the eyes of wild-type C57BL/6J mice without discernible retinal degeneration. Analysis of human serum from patients with AMD recapitulated these dysregulated DHA levels and revealed dysregulation of arachidonic acid (AA) levels as well (∼32% increase in patients with AMD compared with average levels in healthy individuals). From these observations, we then built a statistical model that included levels of DHA and AA from human serum. This model had a 74% probability of correctly identifying patients with AMD from controls. Addition of a genetic analysis for one of the most prevalent amino acid substitutions in the age-related maculopathy susceptibility 2 gene linked to AMD, Ala(69)→Ser, did not improve the statistical model. Thus, we have characterized a reliable method with the potential to detect AMD without a genetic component, paving the way for a larger-scale clinical evaluation. Our studies on mouse models along with the analysis of human serum suggest that our small molecule-based model may serve as an effective tool to estimate the risk of developing AMD. © FASEB.

    To evaluate the effects of copper (Cu) supplementation on the serum lipid profile, meat quality, and carcass composition of goat kids, thirty-five 3-4-month-old Jian Yang big-eared goat kids (BW 20.3±0.6 kg) were randomly assigned to one of seven dietary Cu treatments (n=5/treatment). The dietary Cu concentrations were: (1) control (no supplemental Cu), (2) 20 mg, (3) 40 mg, (4) 80 mg, (5) 160 mg, (6) 320 mg, and (7) 640 mg of supplemental Cu/kg dry matter (DM). Copper was supplemented as CuSO4.5H2O (25.2 % Cu). The goats were fed a high-concentrate basal diet with the different concentrations of supplemental Cu/kg DM for 96 days. The serum lipid profile was determined on day 51 and day 96. Meat quality and carcass composition of longissimus dorsi muscle were measured after the goats were slaughtered at 96 days. Serum total cholesterol, triglycerides, high density lipoprotein-cholesterol (HDL-C), and low density lipoprotein-cholesterol (LDL-C) were not affected by treatment (P>0.18). No differences were observed in drip loss, cooking loss, a* (redness/greenness) and b* (yellowness/blueness) values (P>0.17); however, the 24-h pH value (linear; P=0.0009) and L* (brightness) value (linear; P=0.0128) decreased, and shear force increased (linear; P=0.0005) as Cu supplementation increased. The intramuscular fat (%) increased (linear; P=0.001) as supplemental Cu increased. No differences (P>0.21) in the moisture, crude protein, and ash (%) were observed. Results of this study indicate that supplemental Cu does not modify the serum lipid profile; however, it can impact intramuscular fat content and the meat quality of goat kids.

    Atherogenic effects of ELF-MF exposure have not been studied well so far. Therefore we have hypothesized that ELF-MF exposure might have atherogenic effect by impairing antioxidant function and increasing lipid peroxidation. This study was therefore undertaken to examine the effects of ELF-MF on paraoxonase (PON) activity, antioxidant capacity and lipid peroxidation metabolites. Effects of time on remodeling of antioxidant system were also investigated in this study. Seventy five Wistar rats were randomly allocated into five groups as follows: 1) Sham exposure, 2) Single exposure to 60 Hz, sacrificed immediately after exposure, 3) Single exposure to 60 Hz, sacrificed 72 hours after exposure, 4) Fourteen days of exposure to 60 Hz, sacrificed immediately after exposure, and 5) Fourteen days of exposure to 60 Hz, sacrificed 72 hours after exposure. Blood samples were collected and analyzed. The results were compared using ANOVA and post hoc Tukey HSD for multiple caparisons. Single ELF-MF exposure significantly increased lipid peroxidation (CD and MDA) and increased antioxidant serum activity (HDL, paraoxonase activity, and serum total antioxidant capacity). Chronic ELF-MF exposure increased lipid peroxidation and affected antioxidant system. Free fatty acids levels were significantly increased after both single and two weeks exposure. Chronic exposure led to irreversible changes while acute exposure tended to reversible alterations on above mentioned parameters. According to the results of this study, ELF-MF exposure could impair oxidant-antioxidant function and might increase oxidative stress and lipid peroxidation. Antioxidant capability was dependent on the duration and continuity of ELF-MF exposure.

    A study was conducted to evaluate the effect of adding inulin to diets containing 2 different types of fat as energy sources on performance, blood serum metabolites, liver lipids, and fatty acids of abdominal adipose tissue and breast and thigh meat. A total of 240 one-day-old female broiler chicks were randomly allocated into 1 of 6 treatments with 8 replicates per treatment and 5 chicks per pen. The experiment consisted of a 3 x 2 factorial arrangement of treatments including 3 concentrations of inulin (0, 5, and 10 g/kg of diet) and 2 types of fat [palm oil (PO) and sunflower oil (SO)] at an inclusion rate of 90 g/kg of diet. The experimental period lasted from 1 to 34 d. Dietary fat type did not affect BW gain but impaired feed conversion (P abdominal fat deposition and serum lipid and glucose concentrations. Triacylglycerol contents in liver were higher in the birds fed PO diets. Dietary fat type also modified fatty acids of abdominal and i.m. fat, resulting in a higher concentration of C16:0 and C18:1n-9 and a lower concentration of C18:2n-6 in the birds fed PO diets. The addition of inulin to diets modified (P = 0.017) BW gain quadratically without affecting feed conversion. Dietary inulin decreased the total lipid concentration in liver (P = 0.003) and that of triacylglycerols and very low density lipoprotein cholesterol (up to 31%) in blood serum compared with the control groups. The polyunsaturated fatty acid:saturated fatty acid ratio increased in abdominal and i.m. fat when inulin was included in the SO-containing diets. The results from the current study suggest that the addition of inulin to broiler diets has a beneficial effect on blood serum lipids by decreasing triacylglyceride concentrations The results also support the use of inulin to increase the capacity of SO for enhancing polyunsaturated fatty acid:saturated fatty acid ratio of i.m. fat in broilers.

    Full Text Available 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.

    The association of periodontal bacteria with lipid profile alteration remains largely unknown, although it has been suggested that chronic periodontitis increases the atherosclerotic risk. This cross-sectional study investigated the relationship between the prevalence and total burden of periodontal bacteria and serum lipid profile. Saliva from enrolled participants was collected to detect 4 major periodontal bacteria (Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, and Prevotella intermedia) using Polymerase Chain Reaction method. High-density lipoprotein (HDL) cholesterol, triglycerides (TG), and low-density lipoprotein cholesterol were assessed using blood samples. We compared the averages of each lipid in association with the prevalence of each bacterial species, their burden (low, moderate, and high), and the combination of bacterial burden and periodontal status, defined as periodontitis, using the Community Periodontal Index, after adjustment for other potential confounding factors, by employing general linear models with least square means. A total of 385 Japanese individuals (176 men, 209 women; mean age 69.2 years) were enrolled. The number of bacterial species and their co-existence with periodontitis were significantly related to a decrease in HDL (p for trend Periodontal bacterial burden is suggested to be independently involved in lowering serum HDL level. Our findings suggest that bacterial tests in a clinical setting could be a useful approach for predicting the risk of HDL metabolism dysregulation.

    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.

    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.

    The authors examined the effect of cellular substratum (plastic or amnionic basement membrane (ABM)) and serum additive (fetal bovine (FBS), pork, horse, rat or human) on phospholipid synthesis in alveolar type II cells. The cells were isolated from adult rats, cultured for 48 hours under the various substratum and serum conditions, and then incubated for an additional 2 hours with [1- 14 C] acetate. ABM consistently caused a significant increase in the percent of radiolabel incorporated into phosphatidylcholine (PC) and/or phosphatidylglycerol (PG). Serum also had a significant effect with the highest values of PC and saturated PC being obtained with rat serum and the highest PG values with horse serum. The fatty acid composition of the sera used varied according to species with the largest variations in percent linoleic acid. Supplementing media with linoleic acid resulted in a marked increase in saturated PC values and a fall in PG values. Therefore, they conclude that: 1) ABM improves differentiated function, 2) FBS supplementation may not be optimal, and 3) the different effects of linoleic acid supplementation on PC, saturated PC, and PG values suggests an independent regulation of synthesis for these lipid species in vitro

    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 Objective: To study the effect of telmisartan combined with lipid-lowering drug therapy on serum lipid metabolism index and cytokine levels in patients with type 2 diabetes mellitus complicated by coronary heart disease. Methods: A total of 106 patients with type 2 diabetes mellitus complicated by coronary heart disease who were treated in our hospital between September 2013 and October 2016 were collected and then divided into the control group (n=55 who received conventional treatment + lipid-lowering drug treatment and the observation group (n=51 who received conventional treatment + lipid-lowering drug + telmisartan treatment after the therapies were reviewed. Before and after treatment, serum levels of lipid metabolism indexes, inflammatory mediators and oxidative stress indexes were compared between two groups of patients. Results: Before treatment, the differences in serum levels of lipid metabolism indexes, inflammatory mediators and oxidative stress indexes were not statistically significant between two groups of patients. After treatment, serum TG and LDL-C levels in observation group were lower than those in control group while HDL-C level was higher than that in control group; serum inflammatory mediators IL-6, IL-8, HMGB1 and TNF-α levels were lower than those in control group; serum oxidative stress indexes MDA and ROS levels were lower than those in control group while GSH-Px level was higher than that in control group. Conclusion: Telmisartan combined with lipid-lowering drug therapy can effectively optimize the lipid metabolism and reduce the systemic inflammatory response and oxidative stress response in patients with type 2 diabetes mellitus complicated by coronary heart disease.

    Aging is associated with decreased growth hormone (GH) secretion and plasma insulin-like growth factor-I (IGF-I) levels, increased total and abdominal fat, total and low-density lipoprotein (LDL) cholesterol, and triglycerides, and reduced high-density lipoprotein (HDL) cholesterol. Similar changes in lipids and body composition occur in nonelderly GH-deficient adults and are reversed with GH administration. To examine whether GH/IGF-I axis function in the elderly is related to the lipid profile independently of body fat, we evaluated GH secretion, serum IGF-I and IGF binding protein-3 (IGFBP-3) levels, adiposity via the body mass index (BMI), waist to hip ratio (WHR), dual-energy x-ray absorptiometry (DEXA), and magnetic resonance imaging (MRI), and circulating lipids in 101 healthy subjects older than 65 years. Integrated nocturnal GH secretion (log IAUPGH) was inversely related (P HDL cholesterol (P HDL cholesterol was inversely related to the WHR (P body fat, to be an independent determinant of total (P HDL cholesterol (P HDL in women (P body fat or lipid measures, except for a positive correlation of IGF-I with triglycerides in men. Thus, endogenous nocturnal GH secretion predicts total, LDL, and HDL cholesterol levels independently of total or abdominal fat, suggesting that it is an independent cardiometabolic risk factor in healthy elderly people.

    In this study, we demonstrated the potential of direct infusion mass spectrometry for the lipidomic characterization of Alzheimer's disease. Serum samples were extracted for lipids recovery, and directly analyzed using an electrospray source. Metabolomic fingerprints were subjected to multivariate analysis in order to discriminate between groups of patients and healthy controls, and then some key-compounds were identified as possible markers of Alzheimer's disease. Major differences were found in lipids, although some low molecular weight metabolites also showed significant changes. Thus, important metabolic pathways involved in neurodegeneration could be studied on the basis of these perturbations, such as membrane breakdown (phospholipids and diacylglycerols), oxidative stress (prostaglandins, imidazole and histidine), alterations in neurotransmission systems (oleamide and putrescine) and hyperammonaemia (guanidine and arginine). Moreover, it is noteworthy that some of these potential biomarkers have not been previously described for Alzheimer's disease. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background The xanthophyll carotenoids lutein (L and zeaxanthin (Z are found in and around the macula of the primate retina, where they are termed macular pigment (MP. Dietary L and Z are absorbed with fat in the gut and transported on lipoproteins to the retina. Both MP and serum lipoproteins have been related to risk for neurodegenerative diseases such as age-related macular degeneration (AMD. L and Z are carried on both HDL (related to reduced risk of AMD and LDL (related to increased risk. The purpose of this set of studies was to analyze the relation between L and Z in the serum and retina with the circulating lipid profile. Methods In all experiments, lipoproteins were measured enzymatically from plasma, and MP optical density (MPOD was measured using customized heterochromatic flicker photometry. Experiment 1: Relations between serum L and Z, MPOD and lipoprotein levels. 108 young, healthy subjects (M = 23.2, SD = 4.12 years participated. Lipoprotein levels and MPOD were measured. In a subset of 66 participants, serum L and Z levels were also measured using high-performance liquid chromatography. Experiment 2: Relations between lipoprotein levels and MPOD in statin users. 20 subjects (M = 58.05, SD = 11.08 years taking statin medication and 20 subjects (M = 57.95, SD = 11.03 years not taking satin were recruited for participation. MPOD and lipoprotein levels were measured. Experiment 3: lowering lipoprotein levels to impact MPOD. One individual (aged 41 years with high MP density adhered first to an atorvastatin regimen, then, after a wash-out period, to a rosuvastatin regimen. Results Experiment 1: HDL were significantly (p r = 0.33, to serum L (r = 0.36 and to serum Z (r = 0.26. MPOD was also significantly related to total cholesterol (r = 0.19. Experiment 2: MPOD was not lower in statin users when compared to matched non-statin users, but MPOD decreased significantly with increased duration of statin use (r = −0

    Full Text Available Diabetes mellitus is an important problem amongst human and animals. In veterinary medicine too, diabetes mellitus occurs in many animals particularly household pets. This study was conducted in order to evaluate the effect of date consumption on serumic levels of glucose, triglyceride, cholesterol, LDL, VLDL and HDL in rats suffering from experimental diabetes mellitus. Thirty male wistar rats with the age of 8 weeks and mean body weight of 200±20 gr were selected and divided into 5 groups so that there were 6 rats per group. The groups consisted of day one healthy control, final day healthy control, healthy treatment consuming date, diabetic treatment consuming date and diabetic control group. Diabetic treatment and control groups received 100 mg/kg of alloxan subcutaneously to create experimental diabetes. The two healthy control groups also received equal amounts of normal saline solution subcutaneously. The injections were repeated a week later in all groups. After observing the diabetes symptoms including polydipsia, polyuria, glucosuria and hyperglycemia in groups that were given alloxan, feeding of healthy and diabetic treatment groups with equal ratio of date and pellet was initiated. Final day healthy control group and diabetic control group were fed only with pellet. The groups were fed for 10 days following the start of diabetes symptoms. Blood samples were collected from all groups on day 10. Evaluation of the serumic levels of glucose, cholesterol and LDL revealed statistically significant increase in diabetic control group in comparison with the healthy control groups and also in healthy and  diabetic treatment groups consuming date as compared with diabetic control and healthy groups (p

    Full Text Available Background: Since Urtica dioica is a traditional treatment plant and is used for antihypertensive, antilipidemic and antidiabetic agents, this survey was carried out to evaluate the effect of Urtica dioica decoction on serum glucose and lipid profile in diabetic male rats induced by stereptozotocin (STZ. Materials and Methods: This experiment was performed on 30 Wistar-Albino male rats, weighing 200-250 g, which were divided in sham control (A, diabetic control (B and diabetic test groups (C randomly (N=10. Type I diabetes was induced by single intraperitoneal injection of STZ (65 mg/kg. Test group received 0.40-0.60 ml of Urtica dioica decoction for a month by gavages, control group (B received the same volume of distill water. Group (A did not receive any agent during the experiment period. Finally, animals were anesthetized, sacrificed and blood samples were collected from the cervical vein. Then, serum glucose and lipid profiles were measured by ordinary methods. Data were analyzed by SPSS-11, using ANOVA and post hoc Tukey tests. Results were expressed as mean±SD, and statistical difference was considered significant by p<0.05.Results: Results in the present study showed that fasting blood glucose (FBS, total cholesterol (TCho, triglyceride (TG, LDL, food and water intake were significantly decreased in group C compared with those of group B, but body weight gain was significantly increased compared with that of control group (B.Conclusion: These results indicated that Urtica dioica decoction caused decreased FBS and improved serum lipids in diabetic male rats. Some more studies have shown the same mechanism.

    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

    Prostate cancer (PCa) is one amongst the most common cancersin western men. Incidence rate ofPCa is on the rise worldwide. The present study deals with theserum lipidome profiling of patients diagnosed with PCa to identify potential new biomarkers. We employed ESI-MS/MS and GC-MS for identification of significantly altered lipids in cancer patient's serum compared to controls. Lipidomic data revealed 24 lipids are significantly altered in cancer patinet's serum (n = 18) compared to normal (n = 18) with no history of PCa. By using hierarchical clustering and principal component analysis (PCA) we could clearly separate cancer patients from control group. Correlation and partition analysis along with Formal Concept Analysis (FCA) have identified that PC (39:6) and FA (22:3) could classify samples with higher certainty. Both the lipids, PC (39:6) and FA (22:3) could influence the cataloging of patients with 100% sensitivity (all 18 control samples are classified correctly) and 77.7% specificity (of 18 tumor samples 4 samples are misclassified) with p-value of 1.612×10-6 in Fischer's exact test. Further, we performed GC-MS to denote fatty acids altered in PCa patients and found that alpha-linolenic acid (ALA) levels are altered in PCa. We also performed an in vitro proliferation assay to determine the effect of ALA in survival of classical human PCa cell lines LNCaP and PC3. We hereby report that the altered lipids PC (39:6) and FA (22:3) offer a new set of biomarkers in addition to the existing diagnostic tests that could significantly improve sensitivity and specificity in PCa diagnosis.

    Red palm oil (RPO) is a rich natural source of antioxidant vitamins, namely carotenes, tocopherols and tocotrienols. However, it contains approximately 50 % saturated fatty acids the regular consumption of which could negatively modify lipid profile. The aim of our study was to test whether 7 weeks of RPO supplementation (1 g/kg body weight/day) would affect blood glucose and lipid metabolism in adult male Wistar rats with altered thyroid status. We induced hypothyroidism and hyperthyroidism in rats by oral administration of either methimazole or mixture of thyroid hormones. Different thyroid status (EU - euthyroid, HY - hypothyroid and HT - hyperthyroid) was characterized by different serum thyroid hormones levels (total and free thyroxine and triiodothyronine), changes in the activity of a marker enzyme of thyroid status - liver mitochondrial glycerol-3-phosphate dehydrogenase, and altered absolute and relative heart weights. Fasting blood glucose levels were higher in HT rats in comparison with EU and HY rats, but the changes caused by RPO supplementation were not significant. The achievement of the HY status significantly increased serum levels of total cholesterol, as well as with high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol: 2.43+/-0.15, 1.48+/-0.09, 0.89+/-0.08 mmol/l, compared to EU: 1.14+/-0.06, 0.77+/-0.06, 0.34+/-0.05 mmol/l and HT: 1.01+/-0.06, 0.69+/-0.04, 0.20+/-0.03 mmol/l, respectively. RPO supplementation did not increase significantly levels of blood lipids but tended to increase glutathione levels in the liver. In conclusion, RPO supplementation did not induce the presumed deterioration of glucose and lipid metabolism in rats with three well-characterized alterations in thyroid status.

    Full Text Available We studied the combined effects of wholegrain, fish and bilberries on serum metabolic profile and lipid transfer protein activities in subjects with the metabolic syndrome.Altogether 131 subjects (40-70 y, BMI 26-39 kg/m(2 with impaired glucose metabolism and features of the metabolic syndrome were randomized into three groups with 12-week periods according to a parallel study design. They consumed either: a wholegrain and low postprandial insulin response grain products, fatty fish 3 times a week, and bilberries 3 portions per day (HealthyDiet, b wholegrain and low postprandial insulin response grain products (WGED, or c refined wheat breads as cereal products (Control. Altogether 106 subjects completed the study. Serum metabolic profile was studied using an NMR-based platform providing information on lipoprotein subclasses and lipids as well as low-molecular-weight metabolites.There were no significant differences in clinical characteristics between the groups at baseline or at the end of the intervention. Mixed model analyses revealed significant changes in lipid metabolites in the HealthyDiet group during the intervention compared to the Control group. All changes reflected increased polyunsaturation in plasma fatty acids, especially in n-3 PUFAs, while n-6 and n-7 fatty acids decreased. According to tertiles of changes in fish intake, a greater increase of fish intake was associated with increased concentration of large HDL particles, larger average diameter of HDL particles, and increased concentrations of large HDL lipid components, even though total levels of HDL cholesterol remained stable.The results suggest that consumption of diet rich in whole grain, bilberries and especially fatty fish causes changes in HDL particles shifting their subclass distribution toward larger particles. These changes may be related to known protective functions of HDL such as reverse cholesterol transport and could partly explain the known protective

    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.

    To investigate the relationship of coronary heart disease (CHD)-associated factors-C-reactive protein (CRP) and lipid profiles-with periodontitis in an ethnic Han population. Forty healthy individuals as control, 40 patients with chronic periodontitis (CP), 28 patients with CHD, and 47 patients with both CP and CHD were included in the study. Serum CRP levels, lipid profile concentrations, and three periodontal clinical parameters (probing depth, clinical attachment level, and bleeding on probing) were measured and analyzed. The chi-square test, Student-Newman-Keuls test, analysis of covariance, and a logistic regression analysis were used in this study. The mean CRP level of patients with CP alone was 2.4 +/- 1.5 mg/L. There were significant differences in mean serum CRP levels among groups after confounders were adjusted, with CP+CHD patients having the highest level (7.3 +/- 5.7 mg/L) and the controls the lowest (1.0 +/- 0.6 mg/L) (P periodontal parameters were apparent (P periodontitis is associated with increased CRP levels and decreased HDL cholesterol concentrations, which suggests that there may be some relationship between periodontal inflammation and CHD.

    The current study was designed to investigate the association between serum thyroid hormones and thyroid-stimulating hormone (TSH) levels with lipid profile in depressive disorder. A total of 370 depressive individuals aged 18 years and above were recruited in this cross-section study. All participants underwent a Structured Clinical Interview for DSM-IV (SCID) and recorded the duration of their symptoms. The serum levels of total cholesterol (TCH), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), lipoprotein A (Lp(a)), high-sensitivity C-reactive protein (hsCRP), free thyroxine (FT4), free triiodothyronine (FT3) and TSH levels were determined and the ratios of TCH/HDL-C were assessed. Depressed subjects with a symptom duration ≥3 years had higher TG levels, increased TCH/HDL-C ratios and lower levels of HDL-C, FT4 and TSH compared with depressive patients with a symptom duration <3 years. Correlation analysis displayed that TSH is positively and significantly associated with TCH and LDL-C (p<0.05); the above FT4 and FT3 are negatively, significantly and respectively associated with TCH/HDL-C (p<0.05) and TCH, HDL-C, LDL-C (p<0.05). Multiple linear regression analysis indicated that serum TG and TSH levels are associated with depressive symptom duration. According to our results,These findings indicate that low serum TSH levels are associated with lipid profile, TG and TSH levels have significant association with symptom duration in depressive patients.

    Full Text Available Egg is a major source of dietary cholesterol. The serum lipid response to egg shows marked individual variation, beingpartly genetically determined, and influence by ethnic groups and the overall diet response. In the present investigation, weinvestigated the effect of ingestion of egg and low density lipoprotein (LDL oxidation on serum lipid profile in hypercholesterolemicwomen. Forty hypercholesterolemic women volunteers on a cholesterol-lowering diet (CLD divided into 2 groups ina randomized controlled cross-over study of one egg per day (CLD + 1 egg for 4-week and three eggs per day (CLD + 3 eggsfor 4-week, separated by 4-week period egg-free. The body weight, blood pressure, serum lipid profiles and LDL oxidationwere measured at 4-week intervals. Cholesterol-lowering diet was applied throughout the study by a dietitian using a foodexchange program and 3-day dietary recall every 4 weeks. Compared to the values obtained at baseline, the mean serum totalcholesterol and LDL cholesterol of CLD + 3 eggs was not significantly different from baseline whereas of those of 4-week ofegg-free period and CLD + 1 egg were significantly decreased (238.3±2.9 mg/dL and 228.3±4.7 mg/dL compared to thebaseline (252.2±5.9 mg/dL as was LDL cholesterol (161.2±3.0 mg/dL and 155.7±4.8 mg/dL compared to the baseline (177.5±6.0 mg/dL (p<0.05. The study showed there were no significantly difference the body weight, blood pressure, HDL cholesterol,triglycerides or LDL oxidation during the study. However, serum total cholesterol and LDL cholesterol of 1 or 3 eggsper day after 4-week of egg consumption was not significantly higher than the egg-free period. The study suggests that inhypercholesterolemic women who are on cholesterol-lowering diet, consuming one or three eggs per day did not raise serumcholesterol or LDL cholesterol levels at 4 weeks or result in any change in LDL oxidation.

    Several studies have shown an inverse relationship between selenium status and cardiovascular health, although epidemiologic evidence yielded by the randomized trials did not find a beneficial effect of selenium administration. The aim of this study was to analyze the association between serum selenium levels and lipid profile adjusted by age, sex and other associated factors among a general adult population in Spain. We recruited 372 hospital employee volunteers (60 men and 312 women) with a mean age of 47 (SD: 10.9), whom were given a standardized questionnaire. Serum selenium concentration was measured by electrothermal atomization atomic absorption spectrometry. Serum copper and zinc concentrations were measured using flame atomic absorption spectrometry. The mean of serum selenium was 79.5μg/L (SD: 11.7) with no sex-dependent differences. In the multivariate linear regression analysis, the associated factors with the mean levels of selenium were: age (β=0.223; CI 95%: 0.101-0.345), pselenium≥79.5μg/L were 1.98 (OR=1.98; CI 95% 1.17-3.35; p=0.011) and 2.04 times (OR=2.04; CI 95% 1.06-3.97; p=0.034) more likely to have cholesterol ≥200mg/dL and LDL-c ≥100mg/dL respectively than those with serum selenium selenium was positively associated with increased total and LDL cholesterol but not with HDL-c and triglycerides. More studies are needed in order to confirm the lower serum selenium findings in widows. Copyright © 2016 Elsevier GmbH. All rights reserved.

    The authors propose a simple and reproducible procedure for using iron ions to stimulate serum lipid peroxidation, with TBA-active products being further determined. The procedure determines the reserve of lipids that can be oxidized during oxidative stress. A combination of direct studies and correlation analysis suggests that low-density lipoproteins and very low-density lipoproteins are the major substrates for lipid peroxidation while high-density lipoproteins show a high resistance to this process. The presented procedure may be used to monitor lipid peroxidation in various conditions and upon various exposures in common laboratory practice.

    The invasive mollusk Crepidula fornicata, occurring in large amounts in bays along the French Northeastern Atlantic coasts, may have huge environmental effects in highly productive ecosystems where shellfish are exploited. The present study aims at determining the potential economic value of this marine species in terms of exploitable substances with high added value. Lipid content and phospholipid (PL) composition of this mollusk collected on the Bourgneuf Bay were studied through four seasons. Winter specimens contained the highest lipid levels (5.3% dry weight), including 69% of PLs. Phosphatidylcholine (PC) was the major PL class all year, accounting for 63.9% to 88.9% of total PLs. Consequently, the winter specimens were then investigated for PL fatty acids (FAs), and free sterols. Dimethylacetals (DMAs) were present (10.7% of PL FA + DMA mixture) revealing the occurrence of plasmalogens. More than forty FAs were identified, including 20:5n-3 (9.4%) and 22:6n-3 (7.3%) acids. Fourteen free sterols were present, including cholesterol at 31.3% of the sterol mixture and about 40% of phytosterols. These data on lipids of C. fornicata demonstrate their positive attributes for human nutrition and health. The PL mixture, rich in PC and polyunsaturated FAs, offers an interesting alternative source of high value-added marine lecithin. PMID:25532566

    Objective: To assess the relationship between serum TNF-α, IGF-I levels and lipid peroxidation in patients with fatty liver. Methods: Serum TNF-α, IGF-I (with RIA) levels were examined in 44 patients with fatty liver and 30 controls. Ser- um levels of malondialdehyde (MDA), superoxidase (SOD) were measured with chemocolorimetry in these subjects. Results: Serum levels of TNF-α, IGF-I were significantly higher in patients with fatty liver than those in controls P<0.01 ), while the serum levels of MDA, SOD were significantly lower (P<0.01). Serum levels of IGF-I were negatively correlated with MDA levels ( r -0. 4132, P<0.05), TNF-α levels were positive correlated with MDA levels (r=0.4318, P<0.05). Conclusion: Lipid peroxidation was present in patients with fatty liver, with correlated changes of TNF-α and IGF-I levels. (authors)

    Hyperthyroidism is associated with unpleasant symptoms and hypertension due to increased adrenergic tone. Therefore, beta-blockers are often used in hyperthyroid patients. While some beta-blockers (such as propronolol and metoprolol) may have unwanted effects on lipid profile, carvedilol, a new alpha- and beta-blocker, has been suggested to have some metabolic advantages with respect to lipid profiles in hypertensive patients. However, this has not been shown in hyperthyroid patients. We aimed to compare the effects of two beta-blockers (metoprolol and carvedilol) on the lipid profiles of hyperthyroid patients with hypertension. Thirty patients with hyperthyroidism and hypertension were randomly assigned to receive either carvedilol (n = 15) or metoprolol (n = 15). Thyroid-stimulating hormone (TSH), free T3, free T4, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride, and total cholesterol levels were measured before and following 3 months of treatment. Systolic and diastolic blood pressure, heart rate, TSH, and free T4 improved significantly in both treatment groups. There were no statistically significant changes in the lipid parameters in either of the two treatment groups; however, triglyceride levels slightly decreased with carvedilol treatment. There were also no differences between the two groups in terms of the typical symptoms of hyperthyroidism. Carvedilol might be a preferred agent to treat hyperthyroid patients who have hypertension and dyslipidemia. This is likely due to the possible beneficial effect of carvedilol on lipid parameters, especially on triglyceride levels.

    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.

    Socio-demographic factors affect the development and lives of children and adolescents. We examined links between serum lipids and apolipoproteins and socio-demographic factors in the Leipzig Research Centre for Civilization Diseases Child (LIFE Child) study. The Winkler index and the Family Affluence Scale were used to define characteristics of the social status of 938 boys and 860 girls aged from birth to 19 years. We then used univariate and multivariate regression analyses to examine the socio-demographic impact on total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL), cholesterol triglycerides and apolipoproteins A1 (ApoA1) and B (ApoB). No significant influences on the Winkler index or the Family Affluence Scale were observed regarding the concentrations of serum lipids for total cholesterol or LDL cholesterol. However, and most importantly, children and adolescents with high social status and high family affluence showed significantly higher HDL cholesterol and ApoA1 levels than those with lower individual totals. A higher Winkler index was associated with significantly lower values for triglycerides and ApoB. Adolescents with higher family wealth and social status showed a lower cardiovascular risk profile, as measured by the concentrations of HDL cholesterol and triglycerides as well as ApoA1 and B. ©2016 Foundation Acta Paediatrica.

The study involved 21 healthy volunteers, aged between 20 and 59, BMI 23.12 ± 1.31, who consumed 200 ml SE infusion/day for a period of 30 d. Blood samples were collected before and at the end of the intervention. Significant decrease in triglycerides (14.92%), total cholesterol (15.04%) and LDL-C (24.67%) was established at the end of the study. In addition, HDL-C/LDL-C ratio increased by 42.77%. Improved serum antioxidant capacity and total thiol levels were also established. The results presented in this first human intervention study with SE fruit infusion indicate the potential of the plant to improve lipid profile and serum antioxidant capacity in humans.

    Full Text Available ApoE gene polymorphism has been reportedly associated with serum lipids and cognition. However, very few studies have explored the combined effects of ApoE gene polymorphism and gender on serum lipid profile with subsequent impacts on cognition in Chinese population. A total of 1,000 Chinese community dwellers aged 55 years and above were recruited in this cross-sectional study. Demographic information of the participants was collected using well designed self-administered questionnaires. The Montreal Cognitive Assessment (MoCA test was employed to evaluate the cognitive status of the participants. Semi-quantitative food frequency questionnaire (FFQ was used to obtain the dietary intake information. Fasting venous blood samples were taken for ApoE genotyping and serum lipid measurements. Significant gender differences in cognition, serum lipid profile and dietary fat-rich foods consumption were observed (p < 0.05. Cognition of the subjects was found to be associated with ApoE genotypes (p < 0.05. ApoE rs429358 and rs7412 variants demonstrated a significant effect on cognitive performance in the male subjects; especially within the attention and language cognitive domains as well as the total MoCA score (p < 0.05, respectively. Serum lipid profile and cognition of Chinese adults are significantly linked with gender and ApoE genetic polymorphism. The ApoE variant rs429358 is found to be notably associated with cognition in aging male Chinese population.

    Full Text Available Abstract Background There are few studies to demonstrate the associations between newly addressed lipid profiles and metabolic syndrome (MetS-associated variables. Methods Study participants without medications for hypertension, diabetes, or dyslipidemia {614 men aged 58 ± 14 (mean ± standard deviation; range, 20-89 years and 779 women aged 60 ± 12 (range, 21-88 years} were randomly recruited from a single community at the time of their annual health examination. The association between lipid profiles (total cholesterol (T-C, triglycerides (TG, low-density lipoprotein cholesterol (LDL-C, high-density lipoprotein cholesterol (HDL-C, non-HDL-C, T-C/HDL-C, TG/HDL-C, LDL-C/HDL-C ratio and MetS, Insulin resistance by homeostasis model assessment of insulin resistance (HOMA-IR, and serum HMW adiponectin were analyzed. Results In multiple linear regression analysis, TG/HDL-C and T-C/HDL-C ratios as well as TG showed significantly strong associations with all three MetS-associated variables in both men and women. In men, the ROC curve analyses showed that the best marker for these variables was TG/HDL-C ratio, with the AUC for presence of MetS (AUC, 0.82; 95% CI, 0.77-0.87, HOMA-IR (AUC, 0.75; 95% CI, 0.70-0.80, and serum HMW adiponectin (AUC, 0.67; 95% CI, 0.63-0.71, respectively. The T-C/HDL-C ratio, TG, HDL-C, LDL-C/HDL-C ratio, and non-HDL-C also discriminated these markers; however all their AUC estimates were lower than TG/HDL-C ratio. These results were similar in women. Conclusion In Japanese community-dwelling adults, lipid ratios of TG/HDL-C, T-C/HDL-C, LDL-C/HDL-C as well as TG and HDL-C were consistently associated with MetS, insulin resistance and serum HMW adiponectin. Lipid ratios may be used as reliable markers.

    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

    The actions of thyroid hormone (TH) on lipid metabolism in the liver are associated with a number of genes involved in lipogenesis and lipid metabolism; however, the underlying mechanisms through which TH impacts on lipid metabolism remain to be elucidated. The present study aimed to investigate the effects of hyperthyroidism on the serum levels of the microRNA (miR) miR‑206 and the role of miR‑206 on TH‑regulated lipid metabolism in liver cells. Serum was obtained from 12 patients diagnosed with hyperthyroidism and 10 healthy control subjects. Human hepatoblastoma (HepG2) cells were used to study the effects of triiodothyronine (T3) and miR‑206 on lipid metabolism. Expression of miR‑206 in serum and cells was determined by reverse transcription‑quantitative polymerase chain reaction analysis. Lipid accumulation in HepG2 cells was assessed with Oil Red O staining. Suppression or overexpression of miR‑206 was performed via transfection with a miR‑206 mimic or miR‑206 inhibitor. Serum miR‑206 was significantly decreased in patients with hyperthyroidism compared with euthyroid controls. Treatment of HepG2 cells with T3 led to reduced total cholesterol (TC) and triglyceride (TG) content, accompanied by reduced miR‑206 expression. Inhibition of endogenous miR‑206 expression decreased intracellular TG and TC content in HepG2 cells. By contrast, overexpression of miR‑206 in HepG2 partially prevented the reduction in TG content induced by treatment with T3. In conclusion, serum miR‑206 expression is reduced in patients with hyperthyroidism. In addition, miR‑206 is involved in T3‑mediated regulation of lipid metabolism in HepG2 cells, indicating a role for miR‑206 in thyroid hormone‑induced disorders of lipid metabolism in the liver.

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 (P<0.001, and the fastigium of bone mass loss was in the age range from 51 to 55 in females and from 61 to 65 years in males. After adjustment for sex, there were significant differences in BMD among BMI-stratified groups in both males and females. The subjects with a BMI of <18.5 had a higher incidence of osteoporosis than BMI ≥18.5 in both sexes. BMD in type 2 diabetes mellitus with a BG of >7.0 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.

    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.

    Chronic administration of the poloxamer 407 (P-407), a block copolymer, to elevate serum lipids in mice is a well-established mouse model of hyperlipidemia and atherosclerosis. We tested the hypothesis that the activity of several types of proteases in heart and liver tissue is changed in the early stages of atherosclerosis development. Additionally, we evaluated whether increased serum lipids would induce anxiety in mice, as determined by using a ‘plus-maze’ test. The mice were administered P-407 by intraperitoneal injection twice a week for one month. P-407 administration to mice resulted in a marked increase in total serum cholesterol, atherogenic non-HDL-cholesterol, and especially in total triglycerides, and it also increased anxiety. Morphological changes observed in P-407-treated mice included contractile type changes in cardiomyocytes and foamy macrophages in liver. A significant increase of cysteine proteases cathepsin B and cathepsin L (at 24 h) and aspartate protease cathepsin D (at both 24 h and 5 days) was determined in heart tissue following P-407 administration. However, no changes were noted in heart matrix metalloproteinase activity. The activity of cysteine and aspartate proteases was significantly increased in liver at both 24 hours and 5 days after P-407 administration. In conclusion, administration of P-407 to mice for one month resulted in increased anxiety, and more importantly, there was an increase in the activity of heart and liver proteases secondary to sustained dyslipidemia. It is suggested that heart and liver cysteine and aspartate proteases may represent potential therapeutic targets in the early stages of atherosclerosis. PMID:24170975

    M Bogusławska-Tryk

    Full Text Available ABSTRACT The aim of the research was to determine lipid metabolism indices and fatty acid profile in the blood serum of Ross 308 chickens (n = 48, fed a finisher mixture supplemented with 0, 0.25, 0.5 and 1.0% of lignocellulose. The feeding trial lasted from 21 to 42 d of the birds' age. Blood samples were collected from each chicken at 42d of age from the pterygoid canal vein. In the blood serum the content of triglycerides (TG, total cholesterol (TCHOL and high density lipoprotein (HDL fraction was determined by the spectrophotometric method. The fatty acids concentration was estimated with the use of the gas chromatography method. Lignocellulose in doses of 0.5 and 1.0% significantly reduced the concentration of triglycerides and low density lipoprotein (LDL fraction. Saturated fatty acids (SFA and monounsaturated fatty acids (MUFA content was not affected by dietary treatments whereas lignocellulose significantly influenced the profile of polyunsaturated fatty acids (PUFA from n-3 and n-6 families. Insoluble fiber decreased (p< 0.05 serum concentration of a-linolenic acid (C18:3n-3 and increased share of docosahexaenoic acid (C22:6n-3, dihomogammalinolenic acid (C20:3n-6 and arachidonic acid (C20:4n-6 in total PUFA, compared to the control birds. The results of the present study have shown that the incorporation of limited amounts of lignocellulose into the broiler diet can influence the lipid metabolism in the chickens.

    A new thyroglobulin (Tg) assay employing polyethylene glycol (PEG) for separation of free and antibody bound : 125 I:Tg is described. By choosing a suitable PEG concentration the non-specific precipitation of free [ 125 I]Tg was kept low while both [ 125 I]Tg bound to rabbit anti-Tg immunoglobulins and to human Tg autoantibodies were precipitated. For all sera a 'blank' incubation with no rabbit anti-Tg immunoglobulins was run in parallel with the assay tubes. Hence any interference of Tg autoantibodies would be detected. A two-phase incubation gave a very low detection limit of 0.2 μg/l. The inter-assay coefficient of variation was 9.4% and the intra-assay coefficient of variation was 5.6%. Dilution curves of normal sera were parallel to the standard curve and Tg standards added to normal sera were recovered quantitatively. Twelve out of 60 normal sera from the Randers area contained Tg autoantibodies. The average serum Tg in the 48 sera without antibody was 44.6 ± 5.2 μg/l. (author)

    Full Text Available Aim: To undertake a systematic review and meta-analysis of prospective studies to determine the effect of ginger supplementation on serum C-reactive protein (CRP, lipid profile, and glycaemia. Method: PubMed-MEDLINE, Web of Science, Cochrane Database, and Google Scholar databases were searched (up until July 2016 to identify prospective studies evaluating the impact of ginger supplementation on serum CRP. Random-effects model meta-analysis was used for quantitative data synthesis. Sensitivity analysis was conducted using the leave-one-out method. Heterogeneity was quantitatively assessed using the I2 index. Systematic review registration: CRD42016035973. Results: From a total of 265 entries identified via searches, 9 studies were included in the final selection. The meta-analysis indicated a significant reduction in serum CRP concentrations following ginger supplementation [weighted mean difference (WMD−0.84 mg/L (95% CI −1.38 to −0.31, I2 56.3%]. The WMD for fasting blood glucose and HbA1c was −1.35 mg/dl (95% CI −2.04 to −0.58, I2 12.1% and −1.01 (95% CI −1.28 to −0.72, I2 9.4%, respectively. Moreover, high-density lipoprotein and triglyceride significantly improved after ginger administration [1.16 mg/dl (95% CI 0.52 to 1.08, I2 12.3% and −1.63 mg/dl (95% CI −3.10 to −0.17, I2 8.1%, respectively]. These findings were robust in sensitivity analyses. Random-effects meta-regression revealed that changes in serum CRP levels were independent of the dosage of ginger supplementation (slope −0.20; 95% CI −0.95 to 0.55; p=0.60. Conclusions: This meta-analysis suggests that ginger supplementation significantly reduces serum CRP and improves glycaemia indexes and lipid profile. Randomized control trials with larger sample size and with a longer-term follow-up period should be considered for future investigations.

    Full Text Available A 57-year-old Japanese woman with schizophrenia, who had received long-term treatment with neuroleptics, noticed a painless, pea-sized lump in her right breast. She was admitted to our hospital and a malignant tumor was diagnosed. The patient underwent a conservative radical mastectomy (Patey’s operation. The excised tumor measured 2.0 × 1.2 × 1.1 cm in diameter, and its cut surface was grayish-white. Histologically, tumor cells with clear to foamy cytoplasm were invariably Oil Red O-positive and periodic acid Schiff-negative with or without diastase digestion. The tumor was diagnosed as a lipid-rich carcinoma accompanied by an in situ component. Neuroleptics increase serum prolactin levels by interfering with dopaminergic inhibition of prolactin secretion. Immunohistochemical analysis revealed that, although prolactin was not detected, the tumor cells expressed prolactin receptor, indicating prolactin as the genesis of this neoplasm. In immunohistochemical intrinsic subtype analysis, the tumor was negative for estrogen receptor, progesterone receptor, human epidermal growth factor receptor 1 and 2, and basal cytokeratins (CK5, CK6, and CK14, indicating an unclassified (all-marker negative subtype. Axillary lymph nodes were free of metastasis (stage I, and the patient has been well for 20 years without any evidence of recurrence.

    Full Text Available Abstract Backgound The effects of extremely low-frequency electromagnetic fields (ELF-EMF on the blood serum and liver lipid concentrations of male Wistar rats were assessed. 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.

    Objective To identify potential genes that may be involved in lipid metabolism in rats after treatment with aqueous extract of Arctium lappa L (burdock). Methods Rats were randomly divided into six groups: (i) control (standard diet); (ii) model group (high-fat diet only); (iii) high-fat diet and low-dose aqueous burdock root extract (2 g/kg); (iv) high-fat diet and moderate-dose aqueous burdock root extract (4 g/kg); (v) high-fat diet and high-dose aqueous burdock root extract (8 g/kg); and (vi) a positive control group exposed to a high-fat diet and simvastatin (10 mg/kg). Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis was performed to find the potential candidate genes involved in the modulation of blood lipids by treatment with aqueous burdock root extract. Results Burdock root extract reduced body weight and cholesterol levels in rats. KEGG analysis revealed 113 genes that were involved in metabolic pathways. Of these, 27 potential genes associated with blood lipid metabolism were identified. Conclusions Aqueous extract of burdock root reduced body weight and cholesterol in rats, possibly by modulating the differential expression of genes.

    Objective: To study the changes of serum lipid profile after withdrawl of levo-thyroxine replacement for 4 weeks in patient with radical thyroidectomy for cancer. Methods: Serum thyroid hormones (FT 3 , FT 4 , sTSH, with RIA) levels and lipid profile (Total cholesterol, triglycerides, LDL, HDL, apolipoprotein A-I, apolipoprotein B and Lp (a), with biochemistry) were determined in 46 patients with thyroid carcinoma after operation both during and after 4 weeks' withdrawl of levo-thyroxine replacement treatment. Results: Serum FT 3 , FT 4 levels decreased significantly and serum sTSH, TC, TG, LDL, apo-B, Lp (a) levels increased significantly after 4 weeks' withdrawl of levo-thyroxine replacement (vs during treatment, P 0.05). Conclusion: Hyperlipidaemia did develop in the hypothyroid patients after withdrawl of levo-thyroxine replacement but the degree of which did not not necessarily correlate with the increment of sTSH levels.

    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

    Measurements of Cu, Zn and some lipid concentrations were carried out in serum, bile and gall stone samples collected from 76 patients undergoing surgery for removal of gall stones. The results showed that Cu and Zn were present in micromolar concentration in bile (average Cu concentration = 13.4 ± 0.92, average Zn concentration = 13.4 ± 1.05) and gall stones (average Cu concentration = 2.8 ± 0.16, average Zn concentration = 1.8 ± 0.16 mmol/ g stone). Cross-tabulation of the results showed significant positive linear correlations (p< 0.01) between stone Zn vs. bile cholesterol (r = 0.253), stone Zn vs. bile bilirubin (r = 0.396) (in mixed stones only). This suggested that the more hydrophobic the bile sample, the more Zn co-precipitate with cholesterol or bilirubin. (author). 17 refs., 3 tabs

    CDKL5 mutation is associated with an atypical Rett syndrome (RTT) variant. Recently, cholesterol homeostasis perturbation and oxidative-mediated loss of the high-density lipoprotein receptor SRB1 in typical RTT have been suggested. Here, we demonstrate an altered lipid serum profile also in CDKL5 patients with decreased levels of SRB1 and impaired activation of the defensive system Nrf2. In addition, CDKL5 fibroblasts showed an increase in 4-hydroxy-2-nonenal- and nitrotyrosine-SRB1 adducts that lead to its ubiquitination and probable degradation. This study highlights a possible common denominator between two different RTT variants (MECP2 and CDKL5) and a possible common future therapeutic target. Copyright © 2015 Elsevier Inc.

    Hyperuricaemia and gout are closely related, but hyperuricaemia is an independent risk factor for endothelial damage, autoinflammation and haemodynamic abnormalities. Milk, generally known as a 'purine-free diet', is an essential protein source for patients suffering from hyperuricaemia and gout. As milk still contains different purine ribonucleotides, the new product, depurinized milk, almost free of purine nucleotides and uric acid, was produced. The potential effect of depurinized milk diet on serum uric acid (SUA) level, lipid parameters and blood haematological parameters was explored in rats after 72 h and 15 days, in relation to standard laboratory chow or the untreated milk diet. The beneficial effect on SUA was achieved when depurinized milk draught was given instead of standard chow for 72 h [28.39 ± 4.76 μm; p draughts enhanced haemoglobin concentration (p draught may meet the demand of healthy dairy product for population under hyperuricaemic risk. © 2011 Blackwell Verlag GmbH.

    Metabolic syndrome (MetSyn) increases the risk of type II diabetes and morbidity and mortality due to cardiovascular diseases. Flaxseed oil (FO), as a functional food, is one of the major vegetal sources of essential omega-3 fatty acids. This study aimed to compare the effects of consumption of FO and sunflower seed oil (SO) on lipid peroxidation and other symptoms of MetSyn. This randomized controlled interventional trial was conducted on 60 volunteers aged 30 to 60 years who were diagnosed with MetSyn in Shiraz, Iran. The participants who fulfilled the inclusion criteria were randomly assigned to SO (n = 30, receiving 25 mL/d SO) and FO (n = 30, receiving 25 ml/d FO) groups using block randomization. The diets were identical for all the participants. Blood pressure (BP), serum lipid, fasting blood sugar, and malondialdehyde were measured at baseline and at the end of week 7. The results showed no significant difference between the 2 groups regarding blood lipid levels and fasting blood sugar at the end of the study. However, significant reductions in total cholesterol, low-density lipoprotein cholesterol (5.6% in FO and 10.8% in SO), and triglyceride levels were seen within each group after treatment with FO and SO (P < .05). Nonetheless, between-group changes were significant (<0.05) for systolic BP (mean [±standard deviation {SD}] changes were -14.0 ± 22.41 in the FO group [P = .004] and 0.92 ± 8.70 in the SO group [P = .594]) and diastolic BP (mean [±SD] changes were -4.26 ± 7.44 in the FO group [P = .007] and 1.30 ± 6.91 in the SO group [P = .344]), but marginally significant (P = .053) for malondialdehyde level (mean [±SD] changes were -1.29 ± 1.48 in the FO group [P < .001] and -0.52 ± 1.34 in the SO group [P = .52]). A significant decrease in weight was also found in both groups. However, waist circumference decreased significantly only in the FO group at the end of the study (P < .05). Our results indicated

    Human serum albumin (HSA) patterns have been successfully fabricated for the deposition of lipid bilayer, 1,2-dimyristoyl-sglycerophosphate (DMPA), by making use of the micro-contact printing (μCP) technique and liposome fusion. Confocal laser scanning microscopy (CLSM) results indicate that lipid bilayer has been assembled in HSA patterns with a good stability. Such well-defined lipid patterns formed on HSA surface create possibility to incorporate specific components like channels or receptors for specific recognition. In view of this, microspheres coated with lipid membranes were immobilized in HSA-supported lipid patterns via the hybridization of complementary ss-DNAs. This procedure enables to transfer solid materials to a soft surface through a specific recognition

    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 Cystic fibrosis (CF is an autosomal recessive disease, which affects many organs as it impairs chloride channel. This study was performed to evaluate growth status and its relationship with some laboratory indices such as Cholesterol (chol, Triglyceride (TG, albumin and total protein in children with CF referred to pediatrics center. This study was designed as a cross-sectional study in one year section. Demographic features were compared with standard percentiles curves. Chol, TG, albumin, total protein, prothrombin time, and hemoglobin were measured. Stool exams were also performed. A questionnaire was designed to obtain a history of the first presentation of disease, birth weight, type of labor and parent relativity. In 52% of patients, failure to thrive (FTT was the first presentation. Steatorrhea and respiratory infections were the first presentations, which were seen in 13.7% and 33% of the cases, respectively. The weight of 88% of patients was below the 15th percentile while 82% had a height percentile below 15th. Head circumference in 53% of patients was below the 15th percentile. There was a significant association between weight percentile and serum albumin and total protein (P=0.03 and P=0.007, respectively. There was also a significant relationship between height percentile and serum albumin and total protein (P<0.001 and P<0.000, respectively. The relationships between head circumference and serum albumin and total protein were also significant (P=0.006 and P<0.000, respectively. There was also a significant association between height percentile and hemoglobin. The decrease in anthropometric percentiles leads to decreased serum albumin and total protein.

    Full Text Available 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 medicine. The objective of the present study was to examine the anti-diabetic effects of Capparis spinosa on blood glucose and serum lipids in streptozotocin induced diabetes in male rats. Materials & Methods: In this experimental study conducted at Yasouj University of Medical Sciences in 2010, five groups of animals were selected. Three groups out of five were administered with intraperitoneal injection of streptozotocin to become diabetic. Group I were fed normal diet. Group II of animals received 20 mg/kg/day Capparis spinosa extract. Group III received no treatment (diabetic control and animals of groups IV and V were treated with capparis spinosa fruit extract 20 and 30 mg/kg body weight respectively for three weeks. Blood glucose, triglycerides, total cholesterol, LDL, HDL and body weight were measured in all animals. The collected data was analyzed by the SPSS software using one-way ANOVA. Results: Treatment with the 30 mg/kg/body weight of capparis spinosa fruit extract showed a significant decrease in blood glucose, triglycerides, total cholesterol and LDL, and a significant increase in HDL level. In addition, administration of 20 mg/kg/body weight of capparis spinosa extract decreased blood glucose and lipid levels in diabetic rats. Conclusion: It can be concluded that the oral administration of capparis spinosa extract at the dose of 30 mg/kg/body weight has glucose and lipids lowering activity in diabetic rats.

    Full Text Available Coronary Artery Disease (CAD is a major killer disease throughout the world. Dyslipidemia is a major contributor to the risk of CAD. Several dietary articles traditionally used in India and other South Asian countries reduced dyslipidemia. The present study was undertaken to evaluate the combined effect of Mung bean (Vigna radiata and Elephant foot yam (Amorphophallus paeoniifolius on serum lipids and atherogenic indices in albino rats and to compare it with a standard drug Cholestyramine. Thirty healthy albino rats of both sexes (150–200 g were randomized to 5 groups of 6 animals each. The grouping were done based on the following criteria: Group I: Normal Control Group, Group II: (Standard Group: Cholestyramine resin 5 mg/kg bw, Group III: (Half Dose Group: Drug powder at 540 mg/kg bw, Group IV: (Effective Dose Group: Drug powder at 1080 mg/kg bw, and Group V: (Double Dose Group: Drug powder at 2160 mg/kg bw. Lipid profile was estimated at the beginning and after 30 days of treatment. The Effective and Double doses of the drug reduced Total cholesterol along with levels of Triglycerides, Low density lipoprotein and Very low density lipoprotein levels significantly (p < 0.01 along with a significant (p < 0.01 increase in high density lipoproteins (HDL in rats. There was also significant (p < 0.01 improvement in atherogenic indices like Castelli Risk Index I, Non HDL C/HDL, Castelli risk Index II, TG/HDL, Atherogenic coefficient and Atherogenic Index of Plasma. The combination of powdered sprouted mung bean and yam powder have excellent lipid lowering potential.

    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.

    Twenty-nine healthy volunteers aged 47–69 years old were randomly assigned to a 28-day oral intake of different dark chocolate (DC) formulations. The main group received daily 30 g of proprietary lycopene-containing (L-tug) lycosome formulation of DC with enhanced bioavailability of cocoa flavanols. Two control groups daily consumed either 30 g of regular DC alone or along with 7 mg of lycopene, which corresponds to the amount of lycopene ingested with L-tug formulation. It was found that L-tug was more efficient in reducing diastolic blood pressure (mean value of −6.22 mmHg, 95% CI: 5.00, 8.00) when compared with the regular DC group (−3.00 mmHg, P < 0.05) or the group which ingested the DC and lycopene as two separate formulations (mean reduction of −4 mmHg, 95% CI: 2.47, 6.00, P = 0.0262). Only marginal superiority for L-tug formulation in the reduction in systolic blood pressure was seen. However, the L-tug formulation was the only formulation of DC which affected serum lipids. There was a reduction in total cholesterol (from median 228.00 mg/dL [95% CI: 206.2, 242.5] to 187.00 mg/dL [95% CI: 166.2, 202.2, P < 0.05]) with corresponding decline of low-density lipoprotein (LDL) cholesterol (from a median of 166.00 mg/dL [95% CI: 130.8, 177.0] to 151.00 mg/dL [95% CI: 122.8, 167.4; P < 0.05]) at the end of the intervention period. Similar decline was seen in serum triglycerides (P < 0.05). Serum high-density lipoprotein (HDL) cholesterol, glucose levels, and C-reactive protein (CRP) values remained statistically unchanged in all study groups throughout the intervention period. A superior biological activity of the L-tug lycosome formulation of DC extending beyond its antihypertensive effect to lipid-lowering ability opens up new possibilities for the use of DC for health purposes helping to reduce daily caloric intake without compromising on the health benefits of DC consumption.

    Serum concentrations of several nutrients were measured in 12 captive wild felid species including caracal (Felis caracal), cheetah (Acinonyx jubatus), cougar (Felis concolor), fishing cat (Felis viverrinus), leopard (Panthera pardus), lion (Panthera leo), ocelot (Felis pardalis), pallas cat (Felis manul), sand cat (Felis margarita), serval (Felis serval), snow leopard (Panthera uncia) and tiger (Panthera tigris). Diet information was collected for these animals from each participating zoo (Brookfield Zoo, Fort Worth Zoo, Lincoln Park Zoological Gardens and North Carolina Zoological Park). The nutritional composition of the diets at each institution met the probable dietary requirements for each species except for the pallas cat. Blood samples were collected from each animal (n = 69) and analyzed for lipids (total cholesterol, triacylglycerides, HDL cholesterol and LDL cholesterol), vitamin D metabolites [25-hydroxycholecalciferol (25(OH)D) and 1,25-dihydroxycholecalciferol (1,25(OH)(2)D)], vitamin A (retinol, retinyl stearate and retinyl palmitate), vitamin E (alpha- and gamma-tocopherol) and selected carotenoids. Species differences were found for all except triacylglycerides and 1,25(OH)(2)D. Genus differences were found for retinol, retinyl palmitate, retinyl stearate, gamma-tocopherol and beta-carotene. Circulating nutrient concentrations for many of the species in this study have not been reported previously and most have not been compared with the animals' dietary intakes. The large number of animals analyzed provides a substantial base for comparing the serum nutrient concentrations of healthy animals, for both wild and captive exotic species.

    The objective of this study was to investigate the relationship between serum lipid concentrations and PTSD symptoms in the bereaved after a traumatic familial loss. Eighteen months after the Sewol ferry disaster, 107 subjects who experienced traumatic losses as a result of the accident completed a mental and medical survey as well as laboratory tests for lipid profiles. At 30 months after the trauma, a total of 64 individuals completed a follow-up psychometric survey and biochemical measurements. We performed multiple linear regression analyses, examining the association between PTSD symptoms and lipid profiles. Other potential influences on lipid profiles such as metabolic risk factors, demographic risk factors, and underlying medical history were accounted for. Participants reporting clinically significant PTSD symptoms exhibited lower serum HDL-C levels than those without PTSD symptoms. In addition, we found that the severity of PTSD symptoms and sex could explain the changes in lipid profiles independently of other possible risk factors of changes. The results of this study suggest that PTSD symptoms may contribute to an increased risk for developing metabolic syndrome via detrimental changes in lipid concentrations. Routine screening and multidisciplinary management to prevent metabolic syndrome in individuals who experience traumatic losses would therefore be valuable. Copyright © 2018 Elsevier B.V.

    Full Text Available Abstract Background The association of rs16996148 single nucleotide polymorphism (SNP in NCAN/CILP2/PBX4 and serum lipid levels is inconsistent. Furthermore, little is known about the association of rs16996148 SNP and serum lipid levels in the Chinese population. We therefore aimed to detect the association of rs16996148 SNP and several environmental factors with serum lipid levels in the Guangxi Mulao and Han populations. Method A total of 712 subjects of Mulao nationality and 736 participants of Han nationality were randomly selected from our stratified randomized cluster samples. Genotyping of the rs16996148 SNP was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Results The levels of apolipoprotein (Apo B were higher in Mulao than in Han (P P 0.05; respectively.

    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.

    Full Text Available Abstract Background Monitoring of serum lipid concentrations at the population level is an important public health tool to describe progress in cardiovascular disease risk control and prevention. Using data from two nationally representative health surveys of adults 18–79 years, this study identified changes in mean serum total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C, and triglycerides (TG in relation to changes in potential determinants of serum lipids between 1997–99 and 2008–11 in Germany. Methods Sex-specific multivariable linear regression analyses were performed with serum lipids as dependent variables and survey wave as independent variable and adjusted for the following covariables: age, fasting duration, educational status, lifestyle, and use of medication. Results Mean TC declined between the two survey periods by 13 % (5.97 mmol/l vs. 5.19 mmol/l among men and by 12 % (6.03 mmol/l vs. 5.30 mmol/l among women. Geometric mean TG decreased by 14 % (1.66 mmol/l vs. 1.42 mmol/l among men and by 8 % (1.20 mmol/l vs. 1.10 mmol/l among women. Mean HDL-C remained unchanged among men (1.29 mmol/l vs. 1.27 mmol/l, but decreased by 5 % among women (1.66 mmol/l vs. 1.58 mmol/l. Sports activity and coffee consumption increased, while smoking and high alcohol consumption decreased only in men. Processed food consumption increased and wholegrain bread consumption decreased in both sexes, and obesity increased among men. The use of lipid-lowering medication, in particular statins nearly doubled over time in both sexes. Among women, hormonal contraceptive use increased and postmenopausal hormone therapy halved over time. The changes in lipid levels between surveys remained significant after adjusting for covariables. Conclusion Serum TC and TG considerably declined over one decade in Germany, which can be partly explained by increased use of lipid-lowering medication and improved lifestyle among men. The

    Full Text Available BACKGROUND: Considering rapid global increase in children obesity and high prevalence of dyslipidemia in obese and overweight children, this study aimed to evaluate the effect of an educational course on changes of lipid profile in children.    METHODS: This non-pharmacological clinical trial study was performed on 4-18 year-old children attending outpatient clinics of Isfahan Endocrine and Metabolism Research Center (Iran. Anthropometric measurements were conducted for all children. Fasting blood samples were taken from right hand of the participants at the first laboratory visit. Biochemical tests including measurement of total cholesterol (TC, triglyceride (TG, high-density lipoprotein cholesterol (HDL-C and low-density lipoprotein cholesterol (LDL-C were also carried out. Children took part in one educational session in which they were taught about ways and benefits of having regular physical activity once a day and having healthy foods. All children were followed up for about four months and anthropometrics and biochemical tests were repeated. Data was analyzed using SPSS16.    RESULTS: A total number of 412 children (245 girls and 167 boys were divided into four age groups of under 6, 6-9, 10-13, and 14-18 years old. Baseline anthropometric measures were significantly higher in boys. However, there was no difference between boys and girls in baseline lipid profile. Children's body mass index (BMI z-score increased in all age groups except for 14-18 year-old boys. In boys older than 10 years, there were significant reductions in LDL-C and TC. In girls over 10 years of age, there was a significant increase in HDL-C. Although anthropometric measurements did not change in children (except for 14-18 year-old-boys, there was a significant reduction in children's lipid profile after the study.    CONCLUSION: Our study showed that although one session of interventional education had no significant effects on children's anthropometric

    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.

    The multifactorial mechanisms promoting weight loss and improved metabolism following Roux-en-Y gastric bypass (GB) surgery remain incompletely understood. Recent rodent studies suggest that bile acids can mediate energy homeostasis by activating the G-protein coupled receptor TGR5 and the type 2 thyroid hormone deiodinase. Altered gastrointestinal anatomy following GB could affect enterohepatic recirculation of bile acids. We assessed whether circulating bile acid concentrations differ in patients who previously underwent GB, which might then contribute to improved metabolic homeostasis. We performed cross-sectional analysis of fasting serum bile acid composition and both fasting and post-meal metabolic variables, in three subject groups: (i) post-GB surgery (n = 9), (ii) without GB matched to preoperative BMI of the index cohort (n = 5), and (iii) without GB matched to current BMI of the index cohort (n = 10). Total serum bile acid concentrations were higher in GB (8.90 ± 4.84 µmol/l) than in both overweight (3.59 ± 1.95, P = 0.005, Ov) and severely obese (3.86 ± 1.51, P = 0.045, MOb). Bile acid subfractions taurochenodeoxycholic, taurodeoxycholic, glycocholic, glycochenodeoxycholic, and glycodeoxycholic acids were all significantly higher in GB compared to Ov (P fasting triglycerides (r = −0.40, P = 0.05), and positively correlated with adiponectin (r = −0.48, P < 0.02) and peak glucagon-like peptide-1 (GLP-1) (r = 0.58, P < 0.003). Total bile acids strongly correlated inversely with thyrotropic hormone (TSH) (r = −0.57, P = 0.004). Together, our data suggest that altered bile acid levels and composition may contribute to improved glucose and lipid metabolism in patients who have had GB. PMID:19360006

    Several studies have suggested that dietary selenium deficiency may be associated with an increased risk of coronary heart disease (CHD). In the present study, 55 men and 71 women were selected from participants in a health examination in a rural coastal community in Japan. The mean dietary selenium intake calculated from the simple food frequency questionnaire (SFFQ) was 127.5 micrograms/day. Fish was the major source of dietary selenium and it contributed to 68.7% of the daily total. HDL cholesterol was higher in the middle selenium intake group and in the high selenium intake group than in the low selenium intake group in all subjects and for males, and a significant difference was found between the middle selenium intake group and the low selenium intake group. The atherogenic index was significantly higher in the low selenium intake group than in the middle selenium intake group and in the high selenium intake group in males. GPx activity, total cholesterol and triacylglycerols did not show any significant differences among the three different selenium intake groups. Dietary intake of non-fish Se had a positive correlation with HDL cholesterol, and an inverse correlation with the atherogenic index in all subjects and for females. On the other hand, dietary intake of fish-Se had no relationship with any serum lipids. Non-fish Se is an important factor in selenium status for the prevention of CHD.

    The efficacy of statin therapy may be lost or vary with reduction in compliance and intensity of statin therapy. To study and correlate the quantitative effect of compliance on lipid profile and 3-hydroxyl-3-methylglutaryl coenzyme A reductase (HMGCoA-R) levels in dyslipidemic patients. Compliance to different intensity of statin therapy assessed by pill count was correlated with serum levels of total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (TG), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and HMGCoA-R. Out of 200 patients, 160 received moderate intensity statin therapy whereas 40 were on high intensity statin therapy. The overall mean compliance of patients was 56.7%. The compliance of patients on moderate intensity statin therapy was higher (56.8%) than those on high intensity (56.4%) (p=0.92). There was significant inverse correlation (pstatin therapy was increased above 60%. It is appropriate to improve the compliance to existing statin therapy than switching over to higher intensity statin therapy. Estimation of HMGCoA-R levels may be explored as a surrogate marker to monitor and assess the compliance of patients to statin therapy. Copyright © 2016. Published by Elsevier B.V.

    Percutaneous liver biopsies and blood samples were obtained from 80 multiparous dairy cows in nine Michigan herds. Biopsies and samples were obtained serially over the peripartum period. Thirty-nine cows received 17 g of supplemental myoinositol in the diet to test its use as a possible lipotropic substance and 41 received a placebo. Liver biopsies were assayed for triglyceride (TG) and total myoinositol content. Serum was assayed for dextran precipitable cholesterol and non-esterified fatty acids (NEFA). Inositol supplementation had no effect on any of the lipid variables. There was a significant herd effect on liver inositol, serum dextran precipitable cholesterol and NEFA concentrations. Serum NEFA and liver TG concentrations increased in the immediate postpartum period, while dextran precipitable cholesterol decreased. A significant herd X period interaction existed for liver TG and serum dextran precipitable cholesterol concentrations. Liver TG and serum NEFA concentrations were positively correlated. Excessive infiltration of bovine liver with lipid at calving appears to be an exaggerated manifestation of normal metabolic changes.

    Type-2 diabetes mellitus (DM) and Metabolic syndrome (MetS) are both associated with dyslipidemia which may lead to development of vascular complications. Adiponectin is an anti-inflammatory protein synthesized by the adipose tissue. There is controversy regarding the association of adiponectin with lipid profile. To evaluate the correlation between serum adiponectin concentration and metabolic profile in patients with type-2 DM. A single center cross-sectional study was conducted on 173 patients with type-2 DM (82 males and 91 females). Plasma adiponectin concentration, lipid profile, glucose profile, and anthropometric features were investigated. Insulin resistance was determined using Homeostasis model assessment (HOMA). Correlation of serum adiponectin with lipid profile of patients with type-2 DM was assessed. Adiponectin was negatively correlated with waist circumference (r = -0.16, P = 0.06) and positively with HbA1c (r = 0.19, P = 0.032), total cholesterol (r = 0.23, P = 0.017), LDL (r = 0.30, P = 0.001), SD-LDL (r = 0.41, P < 0.001), and SD-LDL/LDL (r = 0.22, P = 0.023). We found a positive correlation between adiponectin and total cholesterol (r = 0.27, P = 0.055), LDL (r = 0.34, P = 0.026) and SD-LDL (r = 0.41, P = 0.006) in patients with at least 3 components of MetS criteria. Correlation of adiponectin with LDL and SD-LDL remained positively significant with increasing the number of MetS components. In patients with 5 components of MetS, serum adiponectin was significantly correlated with serum triglyceride (r = 0.89). Significant interaction was observed between adiponectin and metabolic syndrome in relation to serum lipid profile. The results of the present study suggest that in patients with type-2 DM and MetS, lipid profile is strongly correlated with blood concentration of adiponectin. The strongest association was observed between serum adiponectin and LDL.

    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

    We examined whether feeding pregnant and lactating rats hydrogenated fats rich in trans-fatty acids modifies the plasma lipid profiles and the expression of adipokines involved with insulin resistance and cardiovascular disease in their 21-d-old offspring. Pregnant and lactating Wistar rats were fed with a control diet (C group) or one enriched with hydrogenated vegetable fat (T group). After delivery, male offspring were weighed weekly and killed at day 21 of life by decapitation. Blood and retroperitoneal, epididymal, and subcutaneous white adipose tissues were collected. Offspring of T-group rats had increased serum triacylglycerols and cholesterol, white adipose tissue plasminogen activator inhibitor-1, and tumor necrosis factor-alpha gene expression, and carcass lipid content and decreased blood leptin and adiponectin and adiponectin gene expression. Ingestion of hydrogenated vegetable fat by the mother during gestation and lactation alters the blood lipid profiles and the expression of proinflammatory adipokynes by the adipose tissue of offspring aged 21 d.

Patients were actively recruited from multidisciplinary care clinics at tertiary children's hospitals from 2010-2012. The control comparison group was recruited by word-of-mouth. Twenty-eight children with myelomeningocele (93% Hispanic; 17 males; 10.0 ± 2.1 years) and 58 controls (84% Hispanic; 30 males; 10.4 ± 2.4 years) provided ≥ 8-hour fasting blood samples with concomitant dual-energy x-ray absorptiometry measurements of body fat. Not applicable. The serum analysis included a lipid panel (cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein), insulin, glucose, leptin, aspartate aminotransferase, alanine transaminase, alkaline phosphatase, albumin, creatinine, calcium, phosphatase, parathyroid hormone, and vitamin D. Children with myelomeningocele had higher body fat (35.2% versus 29.9%, p=0.01) and altered lipid profiles (lower high-density lipoprotein levels, 43.9 mg/dL versus 51.6 mg/dL, P = 0.03) suggesting elevated risk of metabolic syndrome. They also had a higher prevalence of vitamin D deficiency (43% versus 17%, p=0.02) and significantly lower levels of calcium (9.4 mg/dL versus 9.7 mg/dL, P = 0.003) and alkaline phosphatase (187.0 U/L versus 237.0 U/L, P = 0.003). Unexpectedly children with myelomeningocele had lower parathyroid hormone levels (14.5 pg/mL versus 18.4 pg/mL, P = 0.02) than controls despite lower calcium, vitamin D and alkaline phosphatase levels. This suggests an alteration in the sensing mechanism or response of the parathyroid gland to normal physiological stimuli in patients with myelomeningocele. Children with myelomeningocele have abnormal biochemical markers for cardiovascular disease, insulin resistance and bone and mineral metabolism. Early recognition and monitoring of these risk factors in patients with

    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 influences antioxidant defense efficiency in their organisms in comparison to rats fed with standard AIN-93G diet. 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. It was observed that in blood serum of rats fed with modified diet with raw and cooked lyophilised kale addition the lipid oxides level was lower in comparison to control group fed with standard diet (p kale addition. Diet with kale, both raw and cooked, efficiently inhibited the lipid peroxidation process in rats' organisms, ongoing during natural metabolism and during evoked oxidative stress.

    Full Text Available Background Cardiovascular disease is a major cause of mortality and morbidity in people with type 2 diabetes mellitus (T2DM. Studies have consistently identified dyslipidemia as an important risk factor for the development of macrovascular disease. The landmark United Kingdom Prospective Diabetes Study has shown that metformin therapy reduces cardiovascular events in overweight people with T2DM. This study investigates the effect of metformin monotherapy on serum lipid profile in statin-naïve individuals with newly diagnosed T2DM, and whether the effect, if any, is dosage-related. Methods This cohort study enrolled individuals exceeding 20 years of age, with recent onset T2DM, who received at least 12 months of metformin monotherapy and blood tests for serum lipid at 6-month intervals. Exclusion criteria involved people receiving any additional antidiabetic medication or lipid-lowering drug therapy. Lipid-modifying effect of metformin was recorded as levels of serum triglycerides (TG, high density lipoprotein cholesterol (HDL-C, and low density lipoprotein cholesterol (LDL-C measured at six month intervals. Results The study enrolled 155 participants with a mean age of 58.6 years and average glycosylated hemoglobin A1c of 8%. After initiating metformin therapy, LDL-C was significantly reduced from 111 mg/dl to 102 mg/dL at 6 months (P < 0.001, TG was reduced from 132 mg/dl to 122 mg/dL at 12 months (P = 0.046, and HDL-C increased from 45.1 mg/dL to 46.9 mg/dL at 12 months (P = 0.02. However, increasing the dosage of metformin yielded no significant effect on its lipid-lowering efficacy. Discussion Metformin monotherapy appreciably improves dyslipidemia in statin-naive people with T2DM. Its lipid-modifying effect may be attributable to insulin sensitization, reduction of irreversibly glycated LDL-C, and weight loss. In practice, people with dyslipidemia who are ineligible for lipid-lowering agents may benefit from metformin therapy

    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.

    Recent animal studies have demonstrated that hyperlipidemia is associated with poor tendon-bone healing after rotator cuff repair; however, these findings have not been substantiated in human studies. To examine any association between hyperlipidemia and the failure of arthroscopic rotator cuff repair requiring revision surgery and to investigate whether the use of statin lipid-lowering agents had any influence on observed associations. Cohort study; Level of evidence, 3. From a national insurance database, patients who underwent arthroscopic rotator cuff repair with perioperative lipid levels (total cholesterol, low-density lipoprotein [LDL], and triglycerides) recorded were reviewed. For each lipid test, patients were stratified into normal, moderate, and high groups based on published standards. For the total cholesterol and LDL cohorts, a subgroup analysis of patients stratified by statin use was performed. The primary outcome measure was ipsilateral revision rotator cuff surgery, including revision repair or debridement. A logistic regression analysis controlling for patient demographics and comorbidities was utilized for comparison. There were 30,638 patients included in the study. The rate of revision rotator cuff surgery was significantly increased in patients with moderate (odds ratio [OR], 1.20; 95% CI, 1.03-1.40; P = .022) and high total cholesterol levels (OR, 1.36; 95% CI, 1.10-1.55; P = .006) compared with patients with normal total cholesterol levels perioperatively. Within each of these groups, patients without statin use had significantly higher rates of revision surgery, while those with statin prescriptions did not. The absolute risk reduction for statin use ranged from 0.24% to 1.87% when stratified by the total cholesterol level, yielding a number needed to treat from 54 to 408 patients. The rate of revision surgery was significantly increased in patients with moderate (OR, 1.24; 95% CI, 1.10-1.41; P = .001) and high LDL levels (OR, 1.46; 95

    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.

    Full Text Available The influenza glycoproteins, hemagglutinin (HA and neuraminidase (NA, which are associated with the lipid raft, have the potential to initiate virion budding. However, the role of these viral proteins in infectious virion assembly is still unclear. In addition, it is not known how the viral ribonucleoprotein complex (vRNP is tethered to the budding site. Here, we show that HA is necessary for the efficient progeny virion production and vRNP packaging in the virion. We also found that the level of HA does not affect the bundling of the eight vRNP segments, despite reduced virion production. Detergent solubilization and a subsequent membrane flotation analysis indicated that the accumulation of nucleoprotein, viral polymerases, NA, and matrix protein 1 (M1 in the lipid raft fraction was delayed without HA. Based on our results, we inferred that HA plays a role in the accumulation of viral components, including bundled vRNPs, at the lipid raft.

    Background: Dyslipidaemia is a global health issue in developed as well as in developing countries. People with type 2 Diabetes mellitus are more susceptible to develop dyslipidaemia and its related complications. The objective of the study was to assess the effect of sitagliptin a (DPP-4 inhibitor) oral antidiabetic drug on blood sugar, body weight, blood pressure and dyslipidaemia in type 2 diabetic patients. Methods: This 12 weeks open label observational study was conducted at outdoor of diabetic clinic of Sheikh Zayed Medical College/Hospital, Rahim Yar Khan in which newly diagnosed type 2 diabetic patients (n=78) with poor glycaemic control(HbA1c >7.2 percent) were selected. The patient received sitagliptin 50 mg twice daily for 12 weeks. Results: After 12 weeks treatment with sitagliptin, there was a significant reduction in the value of HbA1c from 8.184 percent±0.467 at baseline to 7.0200 percent±0.459 at 12 weeks (p<0.05). Body weight also decreased significantly from 80.21kg±7.156 at baseline to 71.74 kg±6.567 at 12 weeks (p<0.05).Systolic blood pressure decreased (SBP) decreased significantly from 138.17±6.050 mmHg at baseline to 131.22±6.311 mmHg at 12 weeks (p<0.05). Significant changes were also seen in diastolic blood pressure which decreased from 83.14±6.714 mmHg at baseline to 75.28±6.481 mmHg at 12 weeks (p<0.05). Significant reduction in the serum level of total Cholesterol (TC), triglycerides (TG) and Low density lipoprotein cholesterol (LDL-C) were detected (TC: 222.09±13.538 to 209.41±13.475 mg/dl, p<0.05; TG: 170.99±6.940 to 143.45±8.279 mg/dl, p<0.05; LDL-C 120.00±5.804 to 109.06±6.278 mg/dl, p<0.05). High density lipoprotein cholesterol (HDL-C) increased significantly from 42.99±4.836 mg/dl at baseline to 49.97±3.490 mg/dl at 12 weeks. Conclusion: Sitagliptin not only improves blood glucose control but also body weight, blood pressure and lipid profile in type 2 diabetic hyperlipidaemia patients. (author)

    Background Carcinoembryonic antigen (CEA) is commonly used as a serum tumor marker in clinical practice; however, its prognostic value for gastric cancer patients remains uncertain. This meta-analysis was performed to assess the prognostic value of CEA and investigate CEA as a tumor marker. Methods PubMed, EMBASE and other databases were searched for potentially eligible studies. Forty-one studies reporting the prognostic effect of pretreatment serum CEA expression in gastric cancer patients were selected. Data on 14651 eligible patients were retrieved for the meta-analysis. Based on the data extracted from the available literature, the hazard ratio (HR) and 95% confidence interval (CI) for an adverse prognosis were estimated for gastric cancer patients with elevated pretreatment serum levels of CEA (CEA+) relative to patients with normal pretreatment CEA levels (CEA-). Results The CEA+ patients had a significantly poorer prognosis than the CEA- patients in terms of overall survival (OS: HR 1.716, 95% CI 1.594 - 1.848, P 0.05). In the pooled analyses of multivariate-adjusted HRs, the results suggested that pretreatment serum CEA may be an independent prognostic factor in gastric cancer (OS: HR 1.681, 95% CI 1.425 - 1.982; DSS: HR 1.900, 95% CI 1.441 - 2.505; DFS: HR 2.579, 95% CI 1.935 - 3.436). Conclusion/Significance The meta-analysis based on the available literature supported the association of elevated pretreatment serum CEA levels with a poor prognosis for gastric cancer and a nearly doubled risk of mortality in gastric cancer patients. CEA may be an independent prognostic factor for gastric cancer patients and may aid in determining appropriate treatment which may preferentially benefit the CEA+ patients. PMID:25879931

    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.

    Intraperitoneal injection of normal rats with ascorbic acid (10 mg/100 g body weight ) or serotonin (2 mg/100 g body weight) had no harmful effect on the life span. Moreover, the levels of serum total lipids and free fatty acids did not show any significant changes at 3, 7, 10 and 14 days after injection. Administration of ascorbic acid or serotonin to rats at the pre mentioned doses, 15 minutes, before gamma irradiation at 7.5 Gy (single dose ) improved the survival time of rats and the hyperlipemic state recorded after radiation exposure

    The world's fisheries and aquaculture industries produce vast amounts of protein-containing by-products that can be enzymatically hydrolysed to smaller peptides and possibly be used as additives to functional foods and nutraceuticals targeted for patients with obesity-related metabolic disorders. To investigate the effects of fish protein hydrolysates on markers of metabolic disorders, obese Zucker fa/fa rats consumed diets with 75 % of protein from casein/whey (CAS) and 25 % from herring (HER) or salmon (SAL) protein hydrolysate from rest raw material, or 100 % protein from CAS for 4 weeks. The fatty acid compositions were similar in the experimental diets, and none of them contained any long-chain n-3 PUFA. Ratios of lysine:arginine and methionine:glycine were lower in HER and SAL diets when compared with CAS, and taurine was detected only in fish protein hydrolysate diets. Motifs with reported hypocholesterolemic or antidiabetic activities were identified in both fish protein hydrolysates. Rats fed HER diet had lower serum HDL-cholesterol and LDL-cholesterol, and higher serum TAG, MUFA and n-3:n-6 PUFA ratio compared with CAS-fed rats. SAL rats gained more weight and had better postprandial glucose regulation compared with CAS rats. Serum lipids and fatty acids were only marginally affected by SAL, but adipose tissue contained less total SFA and more total n-3 PUFA when compared with CAS. To conclude, diets containing hydrolysed rest raw material from herring or salmon proteins may affect growth, lipid metabolism, postprandial glucose regulation and fatty acid composition in serum and adipose tissue in obese Zucker rats.

    To study the effect of strict prolonged fasting on lipid profile, serum leptin, and high- sensitivity C-reactive protein (hs-CRP) in patients with different stable cardiac illnesses and look for associated new cardiac events and any correlation between entire variables. A total of 56 patients of different stable cardiac illnesses were followed in our cardiology outpatient for 3 months. Data concerning their ability to fast were collected: New York Heart Association class of congestive cardiac failure, angina class, previous myocardial infarction, previous coronary artery bypass graft, percutaneous coronary intervention, severity of valvular lesion, metallic prosthetic valve, and traditional risk factors (diabetes mellitus, insulin requirement, hypertension, hypercholesterolemia, smoking habit, and obesity). Detailed clinical examination and electrocardiography were performed in all patients in three consecutive visits before, during, and after Ramadan. Echocardiographic and angiographic findings and medication plans were collected from patient records. Lipid profile, serum leptin, and hs-CRP were assessed before, during, and after Ramadan. All patients fasted during Ramadan: 80.4% were male, 67.9% were aged >50 years, 71.4% had no change in their symptoms during fasting while 28.6% felt better. No patient has deteriorated. 91.1% of the patients were compliant with medicine during Ramadan, 73.2% after. 89.3% were compliant with diet during Ramadan with no significant change in body weight in the follow-up period. No cardiac or noncardiac morbidity or mortality was reported. High- density lipoprotein-cholesterol (HDL-C) decreased significantly during compared to before fasting (P = 0.012). Low-density lipoprotein-cholesterol (LDL-C) significantly increased during compared to before fasting (P = 0.022). No statistically significant changes were observed in total cholesterol (TC), triglycerides (TG), serum leptin, or hs-CRP. Significant correlation was observed between

    The relationship between serum lipids (cholesterol and triglycerides) and dietary intake was studied as part of a comparative study of cardiovascular diseases. Serum cholesterol (SC) showed a positive regression with intake of saturated fat, animal protein, and dietary cholesterol. The regression with saturated fat was stronger in Japan where weight and SC levels are lower than in the Americanized cohorts, and where dietary fat intake is approx.40% of those in Hawaii and California. The relation between saturated fat intake and SC was stronger in the group with lower relative body weight in both Japan and Hawaii. SC was negatively associated with complex carbohydrate intake and not associated with simple carbohydrate. Regression of nutrient variables with casual triglycerides was weak, although consistently negative with the calorie/weight index. (DLC)

    1974-01-01

    Changes in ftty acid patterns of lipids in serum and erythrocytes induced by dietary fats and in vitro incorporation of fatty acids into erythrocyte membranes were investigated with pigs. On feeding various diets, it was found that fatty acid composition of serum and erythrocytes could be modified and altered toward the fatty acid pattern of the diet. In vitro, the incorporation of labelled fatty acids into erythrocyte membranes was accelerated by the addition of cofactors such as lysolecithin, CoA and ATP. Dietary fats also had certain effects on the incorporation of fatty acids into erythrocyte membranes. Erythrocytes, collected from the blood of pigs fed corn oil, incorporated and also released more labelled linoleate than those of pigs fed hydrogenated soybean oil. Palmitic acid was more slowly incorporated into erythrocyte membranes than linoleic acid in the pigs fed both a commercial chow and scheduled meals, indicating selective esterification of fatty acids in the erythrocyte membranes.

    Familial hypercholesterolemia (FH) is underdiagnosed and public cholesterol screening may be useful to find new subjects. In this study, we aim to investigate the prevalence of FH patients in a hospital screening program and evaluate their atherosclerotic burden using intima-media thickness (IMT). We screened 1575 lipid profiles and included for genetic analysis adults with a low-density lipoprotein (LDL) cholesterol >190 mg/dL and triglycerides 160 mg/dL and triglycerides 8 it was 100%. Mean IMT was higher in FH patients compared to non FH (0.73 [0.61-0.83] vs 0.71 [0.60-0.75] mm, p 190 mg/dL and corneal arcus (p < 0.01 and p < 0.001, respectively). A hospital screening was useful to detect FH subjects with increased atherosclerosis. Also, next-generation sequencing was able to detect new FH mutations.

    Studies have shown that soy protein reduces some atherogenic lipid and lipoprotein concentrations, although lipoprotein(a) concentrations may be increased. The dose response of soy protein has not been established; neither has its effect on plasma total homocysteine. Our objective was to evaluate the effect of 2 doses of soy protein on lipid, lipoprotein, and homocysteine concentrations. Four to 24 wk after being instructed to consume a lipid-lowering diet, 130 men and women with LDL-cholesterol concentrations > or = 4 mmol/L were studied during a parallel group trial in which 4 interventions were assigned randomly. Thirty grams isolated soy protein (ISP) and 10 g cotyledon fiber or 50 g ISP and 16.6 g cotyledon fiber or equivalent doses of casein and cellulose were consumed daily as a beverage for 16 wk. When the 2 groups who consumed ISP were compared with the 2 groups who consumed casein, the differences in the net changes from baseline to week 16 in the concentrations of LDL cholesterol and plasma total homocysteine were -0.26 mmol/L (95% CI: -0.43, -0.09 mmol/L; P = 0.01) and -0.8 micromol/L (-1.4, -0.2 micromol/L; P = 0.005), respectively. The effect of the ISP dose was not significant. There were no significant differences between the 2 ISP and the 2 casein groups in changes in lipoprotein(a), HDL-cholesterol, or triacylglycerol concentrations. Adding 30-50 g soy protein/d to a lipid-lowering diet significantly reduced LDL-cholesterol concentrations without increasing lipoprotein(a) concentrations. Plasma total homocysteine concentrations also decreased, suggesting a novel, possibly antiatherosclerotic effect.

    Geraniol (G) is a natural isoprenoid present in the essential oils of several aromatic plants, with various biochemical and pharmacologic properties. Nevertheless, the mechanisms of action of G on cellular metabolism are largely unknown. We propose that G could be a potential agent for the treatment of hyperlipidemia that could contribute to the prevention of cardiovascular disease. The aim of the present study was to advance our understanding of its mechanism of action on cholesterol and TG metabolism. NIH mice received supplemented diets containing 25, 50, and 75 mmol G/kg chow. After a 3-week treatment, serum total-cholesterol and triglyceride levels were measured by commercial kits and lipid biosynthesis determined by the [(14)C] acetate incorporated into fatty acids plus nonsaponifiable and total hepatic lipids of the mice. The activity of the mRNA encoding HMGCR-the rate-limiting step in cholesterol biosynthesis-along with the enzyme levels and catalysis were assessed by real-time RT-PCR, Western blotting, and HMG-CoA-conversion assays, respectively. In-silico analysis of several genes involved in lipid metabolism and regulated by G in cultured cells was also performed. Finally, the mRNA levels encoded by the genes for the low-density-lipoprotein receptor (LDLR), the sterol-regulatory-element-binding transcription factor (SREBF2), the very-low-density-lipoprotein receptor (VLDLR), and the acetyl-CoA carboxylase (ACACA) were determined by real-time RT-PCR. Plasma total-cholesterol and triglyceride levels plus hepatic fatty-acid, total-lipid, and nonsaponifiable-lipid biosynthesis were significantly reduced by feeding with G. Even though an up-regulation of the mRNA encoding HMGCR occurred in the G treated mouse livers, the protein levels and specific activity of the enzyme were both inhibited. G also enhanced the mRNAs encoding the LDL and VLDL receptors and reduced ACACA mRNA, without altering the transcription of the mRNA encoding the SREBF2. The following

    The present study was conducted to examine the antidiabetic effects of xylitol in a type 2 diabetes rat model. Six-week-old male Sprague-Dawley rats were randomly divided into 3 groups: normal control (NC), diabetic control (DBC) and xylitol (XYL). Diabetes was induced only in the DBC and XYL animal groups by feeding them a 10% fructose solution for 2 weeks followed by an injection (i.p.) of streptozotocin (40 mg/kg body weight). One week after the streptozotocin injection, the animals with a nonfasting blood glucose level of >300 mg/dl were considered to be diabetic. The XYL group was fed further with a 10% xylitol solution, whereas the NC and DBC groups were supplied with normal drinking water. After 5 weeks of intervention, food and fluid intake, body weight, blood glucose, serum fructosamine and most of the serum lipids were significantly decreased, and serum insulin concentration and glucose tolerance ability was significantly increased in the XYL group compared to the DBC group. Liver weight, liver glycogen and serum triglycerides were not influenced by feeding with xylitol. The data of this study suggest that xylitol can be used not only as a sugar substitute but also as a supplement to antidiabetic food and other food products. Copyright © 2012 S. Karger AG, Basel.

  4. Environmental toxin acrolein alters levels of endogenous lipids, including TRP agonists: A potential mechanism for headache driven by TRPA1 activation

    Full Text Available Exposure to airborne toxins can trigger headaches, but the mechanisms are not well understood. Some environmental toxins, such as acrolein, activate transient receptor potential ankyrin 1 (TRPA1, a receptor involved in pain sensation that is highly expressed in the trigeminovascular system. It has been shown in rat models that repeated exposure to acrolein induces trigeminovascular sensitization to both TRPA1 and TRP vanilloid 1 (TRPV1 agonists, a phenomenon linked to headache. In this study, we test the hypothesis that the sensitization of trigeminovascular responses in rats after acrolein exposure via inhalation is associated with changes in levels of endogenous lipids, including TRPV1 agonists, in the trigeminal ganglia, trigeminal nucleus, and cerebellum. Lipidomics analysis of 80 lipids was performed on each tissue after acute acrolein, chronic acrolein, or room air control. Both acute and chronic acrolein exposure drove widespread alterations in lipid levels. After chronic acrolein exposure, levels of all 6 N-acyl ethanolamines in the screening library, including the endogenous cannabinoid and TRPV1 agonist, N-arachidonoyl ethanolamine, were elevated in trigeminal tissue and in the cerebellum. This increase in TRPV1 ligands by acrolein exposure may indicate further downstream signaling, in that we also show here that a combination of these TRPV1 endogenous agonists increases the potency of the individual ligands in TRPV1-HEK cells. In addition to these TRPV1 agonists, 3 TRPV3 antagonists, 4 TRPV4 agonists, and 25 orphan lipids were up and down regulated after acrolein exposure. These data support the hypothesis that lipid signaling may represent a mechanism by which repeated exposure to the TRPA1 agonist and environmental toxin, acrolein, drives trigeminovascular sensitization.

    Cholesterol is reduced in depressed patients, however, these patients have a higher risk for cardiovascular diseases. Electroconvulsive therapy (ECT) is a highly effective treatment option for specific forms of depression. Like for other non-pharmacological therapies targeting depression such as psychotherapy or sleep deprivation, there is a lack of evidence about the effects on peripheral lipid parameters. Our objective was to study the impact of ECT as a non-pharmacological treatment on the peripheral lipid pattern in depressive patients. Peripheral lipid profile composition before and after a course of ECT was analysed in 27 non-fasting inpatients at a university psychiatric hospital with DSM-IV major depressive episode. For the impact of ECT treatment on each lipid parameter a multivariate repeated measurement regression analysis was performed and computed separately for every dependent variable. Total Cholesterol and the cholesterol subtypes HDL and LDL were increased after the treatment compared to baseline. Apolipoprotein A1 was also increased after ECT, whereas apolipoprotein B was not. Indices for the prediction of cardiovascular diseases were unchanged after successful treatment by ECT. The reduction of depressive psychopathology negatively correlated with increases of HDL cholesterol and apolipoprotein A1. Subjects received several antidepressants and other psychotropic medication before and during the ECT. In our preliminary pilot study ECT as a non-pharmacological, effective treatment of depression led to distinct effects on the peripheral lipid pattern. Copyright © 2015 Elsevier B.V.

    This work is directed to study the role of vitamins A and E treatment solely. or in combination against gamma-radiation effects during pro-estrus stage stage on serum glucose, liver content of glycogen, total and lipid fractions (triglycerides, total cholesterol, HDL-and LDL- cholesterol) in serum measured during the estrus stage of the rat estrus cycle. Animals were divided into six groups: untreated control, injected with sesame oil as a vehicle for vitamins injection (i.p.) whole body gamma-irradiated (6 GY), injected with vitamin A Two hours before irradiation, irradiated then injected after one hour with vitamin E, and injected with vitamins A and E pre- and post irradiation. The results demonstrated that irradiation induced significant elevations in the levels of all the measured parameters except in HDL-cholesterol. BOth vitamins ameliorated the recorded elevations during the estrus stage. The combined treatment with vitamins A and E reflected a potent harmony between protective roles of these two antioxidants pre- and post irradiation respectively, that normalized the levels of the measured parameters. The authors suggest that vitamins A and E treatment could enhance and reinforce the natural endogenous defences (steroids, particulary E 2 ) in the body against gamma irradiation and/or other environmental pollutants causing lipid peroxidation, especially during the period of ovulation. Moreover, it is worthy to consider this treatment as a hypolipidemic agent for patients with obesity, atherosclerosis and coronary artery diseases

    Full Text Available Abstract Background Aspirin esterase (AE activity can account for part of aspirin pharmacokinetics in the circulation, possibly being associated with the impairment of aspirin effectiveness as an inhibitor of platelet aggregation. Aims The study was aimed at investigating the correlations of serum AE activity with cholinesterase (ChE and metabolic variables in healthy subjects in comparison to subjects with type 2 diabetes mellitus (T2DM. Methods In cardiovascular disease-free T2DM subjects and healthy controls, the AE activity levels and/or the correlation patterns between AE and the other variables were analyzed. Results Neither AE nor ChE activities were higher in the subjects with T2DM. Serum AE activity strongly correlated with ChE as well as glucose/lipids variables such as total cholesterol and triglyceride in healthy subjects, while the correlations between AE and glucose/lipids variables were not present in T2DM subjects. Conclusions These data may reflect the pathophysiological changes between healthy and T2DM subjects. Our data may thus provide the basis for future studies to unravel the mechanisms.

    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.

    Physical inactivity is one of the major risk factors for dyslipidemia and coronary heart disease. Job resources have been identified as determinants of employees' vigor and physical activity habits. Our first purpose was to comprehensively analyze the series of relationships of job resources, through vigor and exercise habit (i.e., one aspect of physical activity), to serum lipid levels in a sample of Japanese employees in a manufacturing company. Our second purpose was to investigate sex differences in these relationships using a multiple-group path analysis. Data were collected from 4543 employees (men = 4018, women = 525) during a medical checkup conducted in February and March 2012. Job resources (job control, skill utilization, suitable jobs, and meaningfulness of work), vigor, exercise habit, triglyceride, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were measured cross-sectionally. Job resources and vigor were positively associated with exercise habit in both sexes. Exercise habit was inversely associated with triglyceride (-0.03 in men and -0.01 in women, ps jobs and meaningfulness of work. Higher levels of job resources were associated with greater vigor, leading to exercise habit, which in turn, improved serum lipid levels. Longitudinal studies are required to demonstrate causality.

    An alteration in serum cholesterol levels has been suggested as a possible modifier of adrenal uptake of the cholesterol analog, 6β-[ 131 I]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

    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.

    Several studies have explored the relationship between C-reactive protein (CRP), serum lipid levels, risk of suicide and alexithymia or impulsivity in mood or anxiety disorders. However, to date, no study has evaluated the effects of anhedonia on these parameters. The aim of the study was to evaluate the relationship between anhedonia, alexithymia, impulsivity, suicidal ideation, recent suicide attempt, C-reactive protein (CRP) and lipid levels in patients with mood or anxiety disorders. One hundred and twenty-two inpatients with mood or anxiety disorders were recruited. Alexithymia and impulsivity were rated by the 20-item Toronto Alexithymia Scale (TAS-20) and the Barratt impulsivity scale (BIS-10), respectively. Anhedonia and depression were rated by the Temporal Experience Pleasure Scale (TEPS) and the Beck Depression inventory (BDI-II). The TEPS contained two subscales rating anticipatory and consummatory anhedonia. From the BDI-II an anhedonia subscale was extracted rating anhedonia-state. Trait consummatory anhedonia and state anhedonia were associated with low levels of total cholesterol or HDL and low levels of triglycerides respectively. Trait anticipatory anhedonia and state anhedonia were associated with suicidal ideations. The difficulty of identifying feelings component of alexithymia was associated with low levels of total cholesterol and LDL. A high level of suicidal ideation was associated with low levels of HDL. Higher levels of CRP were found in inpatients having recently attempted suicide compared with inpatients who had not attempted suicide. In mood and anxiety disorders, anhedonia and the "difficulty of identifying feelings" component of alexithymia (which has previously been found to be associated with suicide risk) could explain the relationship between serum lipid levels and higher suicide risk.

    Combination of sofosbuvir plus ledipasvir therapy has been expected to enhance sustained virological response (SVR) rates in hepatitis C virus (HCV) genotype 1 chronic infected patients. We analyzed the emergence of drug resistance-associated variants (RAVs) in treatment failure and changes in lipid profiles in sofosbuvir/ledipasvir-treated patients. A total of 176 patients with chronic HCV genotype 1 infection without decompensated liver cirrhosis were treated with sofosbuvir/ledipasvir for 12 weeks. NS5A and NS5B RAVs were determined by either Invader assay or direct sequencing. Serum lipid-related markers were measured at the start of treatment and at week 4 in patients who received sofosbuvir/ledipasvir and ombitasvir/paritaprevir/ritonavir therapies. SVR was achieved in 94.9% (167 out of 176) of patients. SVR12 rate was 97.1% for patietns with low frequncy (75%) of NS5A RAVs. In multivariate regression analysis, higher albumin (odds ratio [OR] = 0.020 for presence; P = 0.007), and NS5A-L31/Y93 RAVs with a population frequency <75% (OR = 29.860 for presence; P = 0.023) were identified as significant independent predictors for SVR12. NS5A-Y93H substitutions were detected in all nine treatment failures at HCV relapse, and three out of six patients with NS5A inhibitor-naïve patients achieved additional NS5A RAVs. Serum low-density lipoprotein cholesterol and apolipoprotein B levels were significantly elevated at week 4 in sofosbuvir/ledipasvir-treated patients. These elevations were greater than in ombitasvir/paritaprevir/ritonavir-treated patients. In conclusion, NS5A multi-RAVs are likely to develop in patients who fail to respond to sofosbuvir/ledipasvir therapy. Inhibition of HCV replication with sofosbuvir might affect lipid metabolism. © 2017 Wiley Periodicals, Inc.

    To identify thresholds of BMI at which similar levels of serum lipids occur in Inuit and in non-Inuit as the impact of obesity on metabolic risk factors differ in Inuit compared to other ethnic groups. Published comparative data among Inuit and non-Inuit whites on BMI and HDL-cholesterol and triglyceride were identified for analysis. A literature search was done for BMI, lipids, Inuit and Greenland or Canada. Studies with data on triglycerides and HDL-cholesterol in Inuit and non-Inuit Caucasians were selected and data were retrieved. Regression equations were computed for BMI and HDL-cholesterol and BMI and triglycerides. BMI for similar levels of lipids in Inuit and non-Inuit and ratios of Inuit/non-Inuit BMI's were calculated. At BMI 25 kg/m2 HDL-cholesterol was 1.7/1.6 mM in Greenland Inuit/non-Inuit women and 1.7/1.5 mM in men in a major comparative study. HDL cholesterol decreased by 0.09 for each 1 kg/m2 increase in BMI. Serum triglycerides were 1.0/1.1 mM for Greenland Inuit/non-Inuit women and 0.9/ 1.4 mM for men at BMI 25 kg/m2. Slopes were around 0.1. A comparative study in Canadian Inuit/non-Inuit gave similar results. The BMI levels required for similar HDL-cholesterol or triglycerides were around 27.5 kg/m2, and Inuit/non-Inuit BMI-ratios were around 1.1. The same degree of dyslipidaemia was seen when Inuit had a 10% higher BMI compared to non-Inuit. This may support the establishment of Inuit-specific BMI cut-offs for the purposes of health screening and population health surveillance.

    Full Text Available Abstract Background Several common genetic polymorphisms in the low density lipoprotein receptor (LDL-R gene have associated with modifications of serum total cholesterol (TC and low density lipoprotein cholesterol (LDL-C levels, but the results are not consistent in different populations. Bai Ku Yao is a special subgroup of the Yao minority in China. The present study was undertaken to detect the association of LDL-R gene Ava Ⅱ polymorphism and serum lipid levels in the Guangxi Bai Ku Yao and Han populations. Methods A total of 1024 subjects of Bai Ku Yao and 792 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples. Genotyping of the LDL-R gene Ava Ⅱ polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Results The levels of serum TC, high density lipoprotein cholesterol (HDL-C, LDL-C, apolipoprotein (Apo A1 and the ratio of ApoA1 to ApoB were lower in Bai Ku Yao than in Han (P - and A+ alleles was 65.5% and 34.5% in Bai Ku Yao, and 80.7% and 19.3% in Han (P -A-, A-A+ and A+A+ genotypes was 42.6%, 45.9% and 11.5% in Bai Ku Yao, and 64.9%, 31.6% and 3.5% in Han (P P 3.20 mmol/L subgroups in Bai Ku Yao (P P P P +A+ genotype had higher serum LDL-C, TC, HDL-C or ApoA1 levels than the subjects with A-A+ and A-A- genotypes. Spearman rank correlation analysis revealed that the levels of LDL-C in Bai Ku Yao and HDL-C in Han were correlated with genotypes (P P Conclusions The association of LDL-R gene Ava Ⅱ polymorphism and serum lipid levels is different between the Bai Ku Yao and Han populations. The discrepancy might partly result from different LDL-R gene Ava Ⅱ polymorphism or LDL-R gene-enviromental interactions.

    To investigate the association of serum lipids and high-sensitivity C-reactive protein (hs-CRP) with obesity in school children and to explore whether hs-CRP levels could be used to predict the presence or absence of obesity 12 months later. The subjects were school children (6-11 years old) in Japan. Blood sampling and physical measurements were performed in school (2001); low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, and hs-CRP levels were measured. Data from children who could be followed 12 months later were analyzed. Subjects weighing 20% or more over his/her standard weight were regarded as obese, and the association of obesity with serum parameters was analyzed. Data from 612 subjects were analyzed (follow-up rate, 75.4%). The mean of each serum parameter was significantly higher (inverse for HDL-C; lower) in obese than that in non-obese children. Logistic regression analysis for obesity at baseline showed that the odds ratio (OR) of hs-CRP was the highest [OR, 2.15; 95% confidence interval (CI), 1.65-2.78 for an interquartile rage (IQR) increase]; the association with triglycerides and LDL-C/HDL-C was significant. At the 12-month follow-up, the OR of high hs-CRP remained the highest of all serum parameters (2.09; 95% CI, 1.63-2.69 for an IQR increase). High levels of triglycerides, LDL-C/HDL-C, and hs-CRP increased the risk of obesity in school children. Hs-CRP is considered to be a better predictor of obesity 12 months later than is LDL-C/HDL-C.

    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.

    In this study, we explored the effects of consumption of banana in thirty hypercholesterolemic and fifteen type 2 diabetic subjects. They were given a daily dose of 250 or 500 grams of banana for breakfast for 12 weeks. Fasting serum lipid, glucose and insulin levels were measured initially as well as every 4 weeks. Daily consumption of banana significantly lowered fasting blood glucose (from 99 ± 7.7 to 92 ± 6.9 and 102 ± 7.3 to 92 ± 5.7 mg x dL(-1) (p profile in diabetic patients were not statistically significant, but for plasma levels of adiponectin, there were significantly increased (from 37.5 ± 9.36 to 48.8 ± 7.38 ngnml1, p consumption of banana (@ 250 g/day) is harmless both in diabetic and hypercholesterolemic volunteers and marginally beneficial to the later.

    During aging there is a tendency towards hyperlipidemia and changes in the distribution of lipoproteins. A decline in the functioning of the body's antioxidant defense system is also observed at this time. The objective of this study was to establish the relationship between serum concentrations of total cholesterol and fractions, triglycerides, and Vitamins C and E. 61 adults over 60 years of age were evaluated from January to March, 2006. Nutritional status was diagnosed by BMI (WHO); serum levels of triglycerides (TG), total cholesterol (TC) and fractions (HDL-c and LDL-c) were determined by enzyme method; Vitamin C (colorimetric method) and Vitamin E by HPLC. ATPIII values were used as a reference for risk of TG, TC, HDL, LDL-c, vitamin C: > 0.9 mg/dL (normal), < 0.9 mg/dL (deficit); vitamin E: = 1300 microg/dL (normal), 1300 = microg /dL (deficit). Consumption of vitamins C and E were estimated by the direct weighing method 3 days per week. According to BMI, 19.7% had nutritional deficit, 39.3% overweight, and 11.5% obesity. TG, TC, LDL-c levels were at risk in females, and HDL-c in both genders. Prevalence of risk for heart disease was: TG (45.2%), HDL-c (51.1%), and LDL-c (52.5%). Consumption and serum levels of vitamin E were low in both genders. There was no association between variables. A significant and positive correlation between TG, TC, LDL-C, serum vitamin E, and BMI was observed. The female group showed overweight, hypertriglyceridemia and hypercholesterolemia, HDL-c and LDL-c at risk, and vitamin E deficiency, all of which are important risk factors for cardiovascular disease in this age group.

    The effects of acidic polysaccharides purified from Gastrodia rhizome on blood pressure and serum lipid levels in spontaneously hypertensive rats (SHR) fed a high-fat diet were investigated. Acidic polysaccharides were purified from crude polysaccharides by DEAE-Sepharose CL-6B. Thirty-six male SHR were randomly divided into three groups: Gastrodia rhizome crude polysaccharide (A), acidic polysaccharide (B) groups, and a control group (C). A 5-week oral administration of all treatment groups was performed daily in 3- to 8-week-old SHRs with a dose of 6 mg/kg of body weight/day. After 5 weeks of treatment, total cholesterol in the acidic polysaccharide group, at 69.7 ± 10.6 mg/dL, was lower than in the crude polysaccharide group (75.0 ± 6.0 mg/dL) and the control group (89.2 ± 7.4 mg/dL). In addition, triglyceride and low-density lipoprotein cholesterol levels in the acidic polysaccharide group were lower than in the crude polysaccharide and control groups. The atherogenic index of the acidic polysaccharide group was 46.3% lower than in the control group. Initial blood pressure after the initial three weeks on the high-fat diet averaged 195.9 ± 3.3 mmHg among all rats. Compared with the initial blood pressure, the final blood pressure in the control group was increased by 22.8 mmHg, whereas it decreased in the acidic polysaccharide group by 14.9 mmHg. These results indicate that acidic polysaccharides from Gastrodia rhizome reduce hypertension and improve serum lipid levels. PMID:22312280

    The public awareness about cell phone safety increased greatly in the last few years as various reports of potential adverse health effects on humans exposed to radiations emitted from cellular phones were published. The aim of the study was to assess the effect of long term cell phone exposure on physiological and hematological parameters along with its impact on serum lipid profiles and a single call effect on heart rate, blood pressure and SpO2(%) of healthy male medical students. The students were divided into two groups, group I (n=22, age 20.63 +/- 1.17 yrs) comprising first year medical students who were never exposed to cell phones at the time of this study and group II (n=35, age 22.00 +/- 1.56 yrs) consists of final year (fourth year) male medical students who were using cell phone for more than four years before this study. The results showed no significant differences the groups in basal heart rate, systolic blood pressure, SpO2(%), or various hematologic parameters. Acute exposure (single call of cell phone with 900 MHz for 1 minute) in both groups showed a significant increase in peak heart rate in group II as compared with group I and a significant decrease in peak SpO2 (%) in group I as compared with group II. Serum total cholesterol, VLDL-cholesterol, and triglycerides concentration were significantly higher in group II (long term cell phone exposed) than in group I, suggesting a mild alteration of lipid profile among group II subjects.

    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 Background: Observational studies showed that intake of whole-grain is associated with a reduced risk of coronary heart disease, hypertension, hyperlipidemia. However, only a few dietary intervention trials have investigated the effect of whole-grain consumption on health outcomes. So we aimed to examine the effect of whole wheat vs. white bread on serum lipid profiles, malondialdehyde (MDA; and C-reactive protein (CRP in overweight and obese patients with coronary stent. Methods: In a randomized, single-blind, parallel trial, 90 participants who had stent and body mass index (BMI≥25 were divided into two groups. Intervention group consumed 150 g of whole-wheat bread daily accompanied with a low-calorie diet and the control group consumed 150 g of white-wheat bread as well as a low-calorie diet. The intervention was continued for 12 weeks. Outcomes such as BMI, lipid profile, MDA, high-sensitivity (hs-CRP, blood pressure, waist and hip circumferences were evaluated at baseline and end of the study. Results: Whole- bread diet in comparison with white diet could significantly reduce weight ,BMI, cholesterol, Low Density Lipoprotein (LDL, systolic blood pressure and MDA. No significant differences were noted between the two diets for triglyceride, High Density Lipoprotein (HDL and hs-CRP levels. Conclusion: The present results suggest that whole bread can significantly reduce oxidative and inflammatory marker level and several cardiovascular risk factors among overweight or obese patients with coronary stent.

    Full Text Available Hypercholesterolemia is one of the risk factors of cardiovascular diseases. High blood cholesterol affects the general health and increases the mortality rate of cardiovascular diseases. High levels of cholesterol in the diet increases LDL levels and decreases the activity of LDL receptors in the liver. Oxidation of vascular LDL lipoproteins increases the development of atherosclerosis. Previous studies have indicated that consumption of antioxidants decreases hypercholesterolemia. This study evaluates the effect of vitamin E supplementation on blood lipid levels in high cholesterol-fed rats. In this experimental study, three groups of male rats (n=10 for each group were used. The control group received basic diet and one of the other two groups received a diet containing one percent cholesterol and while the other received the same diet plus vitamin E supplement (2500 IU/kg in dry matter of the diet for one month. After determining the values of TC, LDL, VLDL, HDL and TG the results indicated that in rats fed with 1% cholesterol apart from HDL and VLDL the other lipids had increased significantly compared with the control group (p

    Full Text Available Data from different studies correlating the serum 25(OHD levels with the metabolic and glycemic parameters in type 2 diabetes patients are still varying. The objective if this study was to describe the correlation between serum 25(OHD levels and some metabolic parameters in Bulgarian type 2 diabetes patients on oral antidiabetic drugs. One hundred type 2 diabetes patients participated - 56 men and 44 women. The mean age and diabetes duration of the women was 59.0 and 9.8 years, of the men - 58.0 and 7.7 years respectively. Complete patient history was taken and physical examination was performed (body weight and height, waist circumference. Body composition was measured on a leg-to-leg body impedance analyzer (TBF-215, Tanita Corp., Tokyo, Japan. Serum levels of vitamin D were measured by electro-hemi-luminescent detection as 25-(ОН D Total (ECLIA, Elecsys 2010, Roche Diagnostics, Switzerland. Glycated hemoglobin A1c was measured on a NycoCard reader (Alere™. Total, HDL-cholesterol (direct and triglycerides were analyzed on a Cobas Integra 400+ analyzer. Correlation analysis was performed on a SPSS 13.0 for Windows platform and included 10 curves. The data were first analyzed for the group as a whole and then separately for men and women as well as in the different vitamin D tertiles. The mean serum 25-OH-vitamin D levels were 23.8 ± 12.1 nmol/l in women and 33.3 ± 20.0 nmol/l in men. We were unable to find any statistically significant correlation between serum 25(OH vitaminand the serum lipids (cholesterol profile and triglycerides. On the contrary, there was a weak correlation with the glycated hemoglobin A1c (cubic model, R2 = 0.178, p = 0.05 and the BMI (inverse model, R2 = 0.101, p = 0.038. The sub-analyses (men versus women or according to tertiles of vitamin D did not produce any additional information. The influence of vitamin D on the parameters of the metabolic control in type 2 diabetes is very weak on an individual level. It

    We aimed to study whether macronutrient intake could modify the association between ApoB Ins/Del and lipid profile, and serum leptin and ghrelin in type 2 diabetes mellitus (T2DM) patients. In this study, 700 T2DM patients were recruited. Anthropometric, biochemical and molecular data were collected, and Diet was assessed using a food frequency questionnaire. The interactions were tested using ANCOVA. Del-allele carriers with high-MUFA and carbohydrate (≥ 12 and ≥ 54% of energy, respectively) had significantly higher TG (P = 0.04) and LDL-C (P = 0.02) compared to Ins/Ins homozygotes, and these were not significant in subjects with low-MUFA and -carbohydrate (ghrelin than Ins/Ins homozygotes (P ghrelin were not significantly lower. These findings indicate that the interaction between ApoB Ins/Del and dietary intake of MUFA, SFA, n-3PUFA, carbohydrate and protein could modulate the serum levels of TG, LDL-C, leptin and ghrelin in T2DM patients.

    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.

    The circadian clock system has been linked to the onset and development of obesity and some accompanying comorbidities. Epigenetic mechanisms, such as DNA methylation, are putatively involved in the regulation of the circadian clock system. The aim of this study was to investigate the influence of a weight loss intervention based on an energy-controlled Mediterranean dietary pattern in the methylation levels of 3 clock genes, BMAL1, CLOCK, and NR1D1, and the association between the methylation levels and changes induced in the serum lipid profile with the weight loss treatment. The study sample enrolled 61 women (body mass index = 28.6 ± 3.4 kg/m(2); age: 42.2 ± 11.4 years), who followed a nutritional program based on a Mediterranean dietary pattern. DNA was isolated from whole blood obtained at the beginning and end point. Methylation levels at different CpG sites of BMAL1, CLOCK, and NR1D1 were analyzed by Sequenom's MassArray. The energy-restricted intervention modified the methylation levels of different CpG sites in BMAL1 (CpGs 5, 6, 7, 9, 11, and 18) and NR1D1 (CpGs 1, 10, 17, 18, 19, and 22). Changes in cytosine methylation in the CpG 5 to 9 region of BMAL1 with the intervention positively correlated with the eveningness profile (p = 0.019). The baseline methylation of the CpG 5 to 9 region in BMAL1 positively correlated with energy (p = 0.047) and carbohydrate (p = 0.017) intake and negatively correlated with the effect of the weight loss intervention on total cholesterol (p = 0.032) and low-density lipoprotein cholesterol (p = 0.005). Similar significant and positive correlations were found between changes in methylation levels in the CpG 5 to 9 region of BMAL1 due to the intervention and changes in serum lipids (p < 0.05). This research describes apparently for the first time an association between changes in the methylation of the BMAL1 gene with the intervention and the effects of a weight loss intervention on blood lipids levels. © 2016 The Author(s).

    An experiment was conducted to investigate the effects of dietary chromium (Cr) source and concentration on growth performance, carcass traits, and some serum lipid parameters of broilers under normal rearing conditions for 42 days. A total of 252 1-day-old Cobb 500 commercial female broilers were randomly allotted by body weight (BW) to one of six replicate cages (six broilers per cage) for each of seven treatments in a completely randomized design involved in a 2 × 3 factorial arrangement of treatments with three Cr sources (Cr propionate (CrPro), Cr picolinate (CrPic), Cr chloride (CrCl3)) and two concentrations of added Cr (0.4 and 2.0 mg of Cr/kg) plus a Cr-unsupplemented control diet. The results showed that dietary Cr supplementation tended to increase the breast muscle percentage compared with the Cr-unsupplemented control group (P = 0.0784), while Cr from CrPic tended to have higher breast muscle percentage compared with Cr from CrCl3 (P = 0.0881). Chromium from CrPic also tended to increase the breast intramuscular fat (IMF) compared with Cr from CrCl3 (P = 0.0648). In addition, supplementation of 0.4 mg/kg Cr tended to decrease low-density lipoprotein cholesterol (LDL-C) (P = 0.0614). Compared with the control group, broilers fed Cr-supplemented diets had higher triglyceride (TG) (P = 0.0129) regardless of Cr source and Cr concentration. Chromium from CrPro and CrPic had lower total cholesterol (TC) compared with Cr from CrCl3 (P = 0.0220). These results indicate that dietary supplementation of Cr has effects on carcass characteristics and serum lipid parameters of broilers under normal rearing conditions, while supplementation of organic Cr can improve carcass characteristics and reduce the cholesterol content in serum.

    High sucrose diets may cause increased serum triglycerides and decreased high density lipoprotein concentration. To determine whether dietary fiber protects against these effects, four groups of six healthy young men were assigned to one of four very high carbohydrate diets providing 0, 18, 36, or 52% of calories as sucrose. Each diet was fed in both low (less than 14 g) and high (greater than 34 g) levels of dietary fiber for 10 days each. Triglycerides increased during the 36 and 52% sucrose diets compared to 0 and 18% sucrose diets, and fiber protected partially against this rise. Serum cholesterol and LDL cholesterol were lower during the 0 and 18% sucrose diets than the 36 or 52% sucrose diets but fiber had no effect. HDL cholesterol decreased during all low fat diets, with a trend toward a greater decrease during the high sucrose diets. The results suggest that fiber protects against carbohydrate-induced lipemia but has no effect on cholesterol during very high carbohydrate diets.

    Chilean aboriginal populations (Mapuche) predominantly live in the region of Araucanía, in the southern part of the country. Their cardiovascular risk factors have not been systematically assessed. To study the prevalence of cardiovascular risk factors in the Mapuche population. Blood pressure, weight, height, dietary habits, fasting serum total cholesterol, HDL cholesterol and triglycerides were measured in 1.948 adults living in 28 Mapuche communities. Thirteen percent of males and 16% of females had high blood pressure. Body mass index was 25.5 kg/m2 in males and 28.1 kg/m2 in females. Forty five percent of women and 24% of men were classified as obese. Mean serum total cholesterol was 186.7 +/- 9.6 mg/dl, HDL cholesterol was 58.7 +/- 30.7 mg/dl, total cholesterol/HDL cholesterol was 3.4 +/- 2 and triglycerides were 155.2 +/- 91.2 mg/dl. Twenty eight percent of males and 9.6% of females smoked. Mapuche individuals have higher levels of HDL cholesterol a better total cholesterol/HDL cholesterol ratio and lower frequency of smoking than non aboriginal Chileans subjects.

    The biological effect of porcine hearts and aortas in a hyperlipidemic rat model was confirmed. Porcine heart and aorta mixture in a 3:1 ratio was blended, canned and sterilized at 115°C and 0.23 Mpa for 40 min. Administration of experimental meat product to the animal model decreased total cholesterol, triglycerides and cholesterol low density lipoproteins by 31.8% (Pproduct compared with hyperlipidemic control rats. Normalization of white blood cell populations was also detected. Monocyte and granulocyte counts in blood of rats fed the meat product decreased by 71.1% (Pproduct compared with hyperlipidemic control rats. The data confirmed the hypolipidemic action of the sterilized meat product. Normalization of white blood cell populations led us to hypothesize an anti-inflammatory action of the new meat product, which, therefore, could be recommended as a part of maintenance therapy for people with lipid disorders or atherosclerosis.

    Women with prior preeclamptic pregnancies have an increased risk for metabolic syndrome and cardiovascular diseases. Maternal preeclampsia has been associated with elevated blood pressure (BP) in offspring during childhood. The aim of our study was to determine whether elevated BP pressure and metabolic changes, such as dyslipidemia, insulin resistance, and increased adrenal hormonal activity, are found in 12-yr-old children of preeclamptic mothers. Sixty children born after preeclamptic pregnancy (PRE) and 60 matched control subjects born after normotensive pregnancy (non-PRE) were studied at the age of 12 yr. The case-control pairs were matched for sex, gestational age (+/-1 wk), and size at birth. We measured BP and concentrations of blood glucose, serum fasting insulin, total and high density lipoprotein cholesterol, triglycerides, cortisol, dehydroepiandrosterone sulfate, and plasma epinephrine (E) and norepinephrine (NE). Low density lipoprotein cholesterol was calculated according to the Friedewald-Fredrickson formula. The PRE children had significantly higher mean systolic (116.4 vs. 113.2 mm Hg; P = 0.021) and diastolic (73.9 vs. 70.3 mm Hg; P = 0.022) BP than the non-PRE children, even when adjusted by current weight and height. At 12 yr of age, systolic BP values correlated inversely with birth weight (r = -0.459; P < 0.001) and length SD scores (r = -0.429; P = 0.001) in the PRE children. The mean concentrations of serum total, low density lipoprotein, and high density lipoprotein cholesterol; triglycerides; fasting insulin; blood glucose; serum cortisol; and dehydroepiandrosterone sulfate did not differ between the PRE and non-PRE groups. However, the mean plasma E concentration was higher in the PRE than in the non-PRE children (0.32 vs. 0.28 nmol/liter; P = 0.042), whereas the mean NE concentration did not differ between these two groups. In conclusion, 12-yr-old children born with maternal preeclampsia had elevated systolic and diastolic BPs and

    The present study aimed to examine the effect of pumpkin (Cucurbita pepo L.) seeds supplementation on atherogenic diet-induced atherosclerosis. Rat were divided into two main groups , normal control and atherogenic control rats , each group composed of three subgroups one of them supplemented with 2% arginine in drinking water and the other supplemented with pumpkin seeds in diet at a concentration equivalent to 2% arginine. Supplementation continued for 37 days. Atherogenic rats supplemented with pumpkin seeds showed a significant decrease (ppumpkin seeds significantly decreased serum concentrations of TC and LDL-C. Our findings suggest that pumpkin seeds supplementation has a protective effect against atherogenic rats and this protective effect was not attributed to the high arginine concentrations in pumpkin seeds.

    Growing evidence suggests that oxidative stress (OS) may be associated with the pathophysiology underlying schizophrenia (SZ). Some studies indicate that nutritional supplements offer protection from OS, but there is no data about the effect of a hypocaloric diet on OS in this population. Therefore, we aimed to study the effect of a hypocaloric dietary intervention on OS in subjects with SZ. A cross-sectional study of 96 participants in outpatient treatment for SZ comprised patients separated into two groups: one group of subjects followed a hypocaloric diet (HD) program (n=42), while the other group followed a regular diet (RD) with no nutritional restrictions (n=54). The serum total radical-trapping antioxidant parameter (TRAP), total antioxidant reactivity (TAR) and thiobarbituric acid reactive species (TBARS) levels were assessed. TRAP levels were lower and TBARS levels were higher in the HD group than in the RD group (p=0.022 and p=0.023, respectively). There were no differences in TAR levels between the groups. Additionally, there was a positive correlation between TRAP and TBARS levels after adjusting for BMI and clozapine dose (partial correlation=0.42, pdiet and the levels of TRAP, TBARS, and TAR. Subjects with SZ on a hypocaloric diet displayed different OS parameters than those not following a HD. Serum TRAP levels were lower and TBARS levels were higher among SZ subjects with HD compared to SZ subjects without HD. Lower TRAP levels may reflect decreased oxidative stress, whereas higher TBARS levels most likely reflect a biochemical reaction to the decreased TRAP levels. Additionally, TAR levels were similar between groups, suggesting a similar quality of antioxidant defenses, despite quantitative differences between the two dietary protocols in SZ patients under outpatient care.

    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.

    This study was conducted to investigate whether the free fatty acid (FFA) content of yellow grease would influence the performance and carcass characteristics of broiler chicks. A total of 432 one-day-old, male Arbor Acres broilers were randomly allotted to 1 of 4 treatments, with each treatment being applied to 6 pens of 18 chicks. The dietary treatments were based on corn and soybean meal and were supplemented with either soybean oil (2.86% FFA) or yellow grease with a low (2.74%), medium (12.59%), or high (19.05%) FFA content. The fat sources were supplemented at 1.5% of the diet during the starter phase (0 to 21 d) and at 3.0% of the diet during the grower phase (22 to 42 d). From d 0 to 42, the BW gains of chicks fed diets containing soybean oil and yellow grease with 2.74% FFA were similar. As the FFA level in the yellow grease increased, the BW gain of chicks decreased (P dressing percentage and the percentage of breast muscle in the carcass were significantly (P < 0.01) lower for broilers fed any yellow grease diet compared with birds fed soybean oil. In contrast, abdominal fat was significantly increased in diets containing yellow grease. These results demonstrate that the performance of birds fed yellow grease with a low content of FFA was essentially equal to that of birds fed soybean oil. However, because yellow grease samples containing FFA levels greater than 2.74% negatively affected bird performance, producers should exercise caution with regard to feeding broilers yellow grease with an elevated FFA content. In 42-d-old broilers, serum total cholesterol and low-density lipoprotein cholesterol levels were elevated in birds fed yellow grease, regardless of the dietary level. In contrast, serum high-density lipoprotein cholesterol and triglyceride levels were unaffected by dietary treatment. Although dietary FFA may influence triglyceride-rich lipoprotein metabolism in broilers, an explanation for the observed effects remains elusive.

    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.

    Obesity affects millions of people worldwide, constituting a public health problem associated with premature mortality. Agave fructans decrease fat mass, body and liver weight, and generate satiety in rodents. In the present study the effects of agave fructans on weight control, lipid profile, and physical tolerability were evaluated in obese people. Twenty-eight obese volunteers were randomly divided into two groups. In the first group, 96 mg/bw of agave fructans was administered for 12 weeks; in the second group, maltodextrin as a placebo was administered for 12 weeks. All participants consumed a low-calorie diet of 1500 kcal/day. Anthropometric and biochemical measurements were taken at baseline and at the end of the study. The body mass index (BMI) of the agave fructans treated group was reduced significantly from the baseline to the final measurements. Hip and waist circumferences decreased statistically in both groups. A decrease of 10% in total body fat was observed in the agave fructans treated group, resulting in a statistically significant difference in the final versus baseline measurements between the Agave fructans treated group and the placebo treated group. Triglycerides were reduced significantly in the agave fructans treated group. Glucose values did not change in either group. Agave fructans intake was safe and well tolerated throughout the study. The results showed that the ingestion of agave fructans enhanced the decrease in BMI, the decrease in total body fat, and the decrease in triglycerides in obese individuals who consume a low-calorie diet.

    Background. Kidney disease is commonly accompanied by hyperuricemia. However, the contribution of serum uric acid (SUA) to kidney injury is debated. Our objective was to assess the long-term prediction of renal failure by SUA. Methods. Visit 2 participants in the Jerusalem Lipid Research Clinic cohort with normal baseline kidney function were followed for 24–28 years. SUA levels were assessed for associations with acute renal failure (ARF) and chronic renal failure (CRF) as defined by hospital discharge records, and mortality, ascertained through linkage with the national population registry. Results. Among 2449 eligible participants (1470 men, 979 women aged 35–78 years in 1976–79), SUA was positively linked with male sex, serum creatinine and components of the metabolic syndrome but was lower in smokers and in diabetic subjects. The 22- to 25-year incidence of hospital-diagnosed kidney failure (145 first events, 67% CRF) and the 24- to 28-year mortality (587 events) were higher in subject with hyperuricemia (>6.5 mg/dL in men and >5.3 mg/dL in women, reflecting the upper quintiles), independent of baseline kidney function and covariates. Hyperuricemia conferred adjusted hazard ratios of 1.36 (P = 0.003), 2.14 (P < 0.001) and 2.87 (P = 0.003) for mortality, CRF and ARF, respectively. Conclusions. SUA predicts renal failure incidence and all-cause mortality independently of demographic and clinical covariates. These results lend support to the undertaking of clinical trials to examine the effect of uric acid-lowering strategies on kidney outcomes. PMID:21220750

None of the patients had history of diabetes or hypertension. The background intestinal uptake on PET was visually graded (low vs. high uptake group and quantitatively measured using the maximal standardized uptake value (SUVmax. SUVmax of 7 bowel segments (duodenum, jejunum, ileum, cecum, hepatic flexure, splenic flexure, and descending colon-sigmoid junction were averaged for the total bowel (TB SUVmax. Age, body mass index (BMI, fasting blood glucose level (BST, triglyceride (TG, cholesterol, high density lipoprotein (HDL, and low density lipoprotein (LDL were the considered CMR factors. The relationships between background intestinal 18F-FDG uptake on PET and diverse CMR factors were analyzed.The visual grades based on background intestinal 18F-FDG uptake classified 100 (30.7% patients into the low uptake group, while 226 (69.3% were classified into the high uptake group. Among CMR factors, age (p = 0.004, BMI (p<0.001, and TG (p<0.001 were significantly different according to visual grade of background intestinal 18F-FDG uptake. Quantitative TB SUVmax showed significant positive correlation with age (r = 0.203, p<0.001, BMI (r = 0.373, p<0.001, TG (r = 0.338, p<0.001, cholesterol (r = 0.148, p = 0.008, and LDL (r = 0.143, p = 0.024 and significant negative correlation with HDL (r = -0.147, p = 0.022. Multivariate analysis indicated that BMI and TG were independent factors in both visually graded background intestinal 18F-FDG uptake (p = 0.027 and p = 0.023, respectively and quantitatively measured TB SUVmax (p = 0.006 and p = 0.004, respectively.Increased background intestinal 18F-FDG uptake on PET may suggest alteration of lipid metabolism and risk of cardio-metabolic disease in non

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.

    Elevated serum lipid concentrations in childhood are thought to be risk factors for the development of cardiovascular disease later in life. The present study aims to provide age- and gender-related reference intervals for total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, and non-HDL cholesterol in healthy school children. We also investigated the prevalence of dyslipidaemia using the published criteria for these biomarkers. Venous blood and anthropometric data were collected from 1340 children in the HOPP study, aged between 6 and 12 years. Age- and gender-related reference intervals (2.5th and 97.5th percentiles) were established according to the IFCC recommendations, using the software RefVal 4.10. Gender differences were observed for total cholesterol and non-HDL cholesterol, but not for HDL cholesterol. Age differences were observed for total cholesterol. The reference intervals were in the range of 3.1-5.9 mmol/L for total cholesterol, 1.0-2.4 mmol/L for HDL cholesterol and 1.4-4.2 mmol/L for non-HDL cholesterol. Dyslipidaemia prevalence was as follows: increased TC 9.6%, decreased HDL 1.6%, and increased non-HDL 5.6%. Age- and gender-related reference intervals in a Norwegian population are similar to those reported in other countries. The prevalence of dyslipidaemia among Norwegian children is significant, emphasising the importance of appropriate reference intervals in clinical practice.

    Full Text Available Abstract Background Rapeseed oil is the principal dietary source of monounsaturated and n-3 polyunsaturated fatty acids in the Northern Europe. However, the effect of rapeseed oil on the markers of subclinical atherosclerosis is not known. The purpose of this study was to compare the effects of dietary intake of cold-pressed turnip rapeseed oil (CPTRO and butter on serum lipids, oxidized LDL and arterial elasticity in men with metabolic syndrome. Methods Thirty-seven men with metabolic syndrome completed an open and balanced crossover study. Treatment periods lasted for 6 to 8 weeks and they were separated from each other with an eight-week washout period. Subjects maintained their normal dietary habits and physical activity without major variations. The daily fat adjunct consisted either of 37.5 grams of butter or 35 mL of VirginoR CPTRO. Participants were asked to spread butter on bread on the butter period and to drink CPTRO on the oil period. The fat adjunct was used as such without heating or frying. Results Compared to butter, administration of CPTRO was followed by a reduction of total cholesterol by 8% (p Conclusion Cold-pressed turnip rapeseed oil had favourable effects on circulating LDL cholesterol and oxidized LDL, which may be important in the management of patients at high cardiovascular risk.

    Full Text Available The blood serum lipid profile of women with Gestational Diabetes Mellitus (GDM is still under study. There are no data on the serum lipid profile of GDM patients with more severe (insulin treated compared to milder forms (diet treated GDM. The aim of our study was to analyze the blood serum lipid profile of patients with milder versus more severe forms of GDM and to compare these findings with those of healthy pregnant women. This cross-sectional analytical study included 30 insulin-treated GDM, 30 diet-only GDM and 30 healthy pregnant women. Serum lipid was extracted from the 90 participants and their lipid profiles were analyzed by lipid fingerprinting using liquid-chromatography-mass spectrometry. A total of 143 parent ions were differentially represented in each of the three groups, belonging to the following classes: Glycerophospholipids, Sterol Lipids, Sphingolipids, Prenol Lipids, Fatty Acyls and Glycerolipids. There were significant differences in the lipid profiles of healthy pregnant women compared to GDM patients and also between milder versus more severe forms of GDM. There are marked differences in lipid fingerprinting between healthy pregnant women compared to those with GDM in the third trimester. Moreover, the lipid profile of women with more severe forms of GDM differs considerably from that of women with milder forms of GDM. These findings may be useful to help clarify the pathogenesis of milder and more severe forms of GDM.

    The subjects of the study were 30 patients with coronary heart disease (19--with stable, and 11--with instable angina), and 15 practically healthy individuals. The study included measurement of the levels of homocysteine (HC), total cholesterol, cholesterol of low-density lipoproteins, cholesterol of high-density lipoproteins, and lipidperoxidation (LP) products (TBA-reactive products), as well as coagulo-fibrinolytic parameters. The study revealed that patients with instable angina had significantly higher levels of HC and TBA-reactive products compared to those with stable angina and healthy controls. HC level correlated with LP processes in CHD patients (r = 0.55). Methionine loading allowed revealing latent hyperhomocysteinemia.

    Full Text Available The Trp719Arg allele of KIF6 rs20455, a putative risk factor for CHD especially in those with elevated low-density lipoprotein cholesterol (LDL-C, was investigated in Filipino-American women (FAW, n=235 participating in health screenings in four cities. The rs20455 genotype of each subject was determined by a multiplex assay using a Luminex-OLA procedure. The risk allele Trp719Arg was present in 77% of the subjects. The genotype distribution was 23% Trp/Trp, 51% Arg/Trp, and 26% Arg/Arg. Genotype did not predict the presence of CHD risk factors. Moreover, LDL-C, HDL-C, and triglycerides mean values did not vary as a function of genotype. However, those with the Arg/Arg genotype on statin medication exhibited a significantly higher mean triglycerides level (P<0.01. Approximately 60% of participants regardless of genotype exhibited LDL-C levels ≥100 mg/dL but were not taking medication. Approximately 43% of those with the Trp719Arg risk allele on statins exhibited elevated LDL-C levels. Our study suggests that the Trp719Arg allele of KIF 6 rs20455 is common among Filipino-American women; thus, even with borderline LDL-C levels would benefit from statin treatment. Secondly, many participants did not exhibit guideline recommended LDL-C levels including many who were on statin drugs.

    The Trp719Arg allele of KIF6 rs20455, a putative risk factor for CHD especially in those with elevated low-density lipoprotein cholesterol (LDL-C), was investigated in Filipino-American women (FAW, n = 235) participating in health screenings in four cities. The rs20455 genotype of each subject was determined by a multiplex assay using a Luminex-OLA procedure. The risk allele Trp719Arg was present in 77% of the subjects. The genotype distribution was 23% Trp/Trp, 51% Arg/Trp, and 26% Arg/Arg. Genotype did not predict the presence of CHD risk factors. Moreover, LDL-C, HDL-C, and triglycerides mean values did not vary as a function of genotype. However, those with the Arg/Arg genotype on statin medication exhibited a significantly higher mean triglycerides level (P Filipino-American women; thus, even with borderline LDL-C levels would benefit from statin treatment. Secondly, many participants did not exhibit guideline recommended LDL-C levels including many who were on statin drugs. PMID:24587901

    Despite a high content of saturated fat, evidence from observational studies indicates that the consumption of dairy products may have a neutral effect or may be inversely associated with the risk of CVD. We aimed to examine whether milk minerals modify the effect of saturated fat on serum lipid profile. We present data from two studies. Study I had a randomised, blinded, parallel design (n 24 pigs) with a 10 d adaptation period during which a high-fat diet was fed to the pigs and a 14 d intervention period during which the same diet either enriched with milk minerals (MM group) or placebo (control group) was fed to the pigs. Study II had a randomised cross-over design (n 9 men) where the subjects were fed either a high-fat diet enriched with milk minerals (MM period) or a regular diet (control period). In both the studies, blood variables were measured before and after the intervention and faecal and urine samples were collected at the end of the dietary periods. The increase in plasma total cholesterol and LDL-cholesterol concentrations but not in HDL-cholesterol concentration was markedly lowered by milk minerals in both the studies. In the animal study, baseline adjusted total cholesterol and LDL-cholesterol concentrations in the MM group were 11% (P = 0.004) and 13% (P = 0.03) lower compared with those in the control group after the intervention. Similarly in the human study, baseline adjusted total cholesterol and LDL-cholesterol concentrations were 6% (P = 0.002) and 9% (P = 0.03) lower after the MM period compared with those in the control period. HDL-cholesterol concentration was not lowered by milk minerals. These short-term studies indicate that the addition of milk minerals to a high-fat diet to some extent attenuates the increase in total cholesterol and LDL-cholesterol concentrations, without affecting HDL-cholesterol concentration.

    The influence of diet content and its supplementation with chosen group of B vitamins on the intake of feeding stuff increase, changes of body mass, accumulation of fat tissue, lipids and lipoproteins concentration in the blood of female rats were under research. The animals, aged 5 months, were divided into three groups (8 persons each) and fed ad libitum with granulated Labofeed B type mix. Group I with the basic mix containing among other things whole grain, Group II with a modified mix, where whole grain was replaced by wheat flour and saccharose and Group III with modified mix supplemented in excess with chosen vitamins of B group. This experiment took 6 weeks during which the amount of consumed feed was currently evaluated, and the body mass was controlled weekly. After finishing the experiment in the obtained serum the concentration of triacylglycerols, complete cholesterol with enzyme method and the content of cholesterol fractions with electrophoretic separation method were determined. Analysis of fat content in muscles and livers was conducted and the amount of round the bodily organ fat was determined. It was ascertained that change of the content of the feed and its supplementation with the chosen B group vitamins did not influence in a substantial way its intake and the increase of body mass, however it had influenced substantially, in animals fed with the modified feed the accumulation of round the organ fat and in supplemented the intramuscular fat. Analysis of the results enabled the ascertainment that the diet supplementation with chosen ingredients of the B group vitamins corrects the negative effect of accumulation of the visceral fat tissue as a result of the change of its contents, caused substantial increase in the concentration of triacylglycerols, complete cholesterol and its fractions VLDL- and LDL- with simultaneous decrease of the concentration of cholesterol HDL- fractions.

    The present study was undertaken to investigate the protective effect of royal jelly (RJ) against toxicity induced by a synthetic pyrethroid insecticide, lambda-cyhalothrin (LCT), in Swiss albino mice. Animals were randomly divided into six groups of six animals each. The control group received distilled water alone, whereas mice in the treatment groups received RJ alone (100 or 250 mg/kg of body weight), LCT alone (668 ppm), or RJ+LCT for 21 days. All mice (100%) survived until the end of experiment and were sacrificed at the end of 24 hours. Blood, bone marrow, and liver and kidney tissues were analyzed for aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), creatinine, malondialdehyde (MDA), and reduced glutathione (GSH) levels and micronucleus (MN) frequency, chromosomal aberrations (CAs), and pathological damages. Serum AST, ALT, BUN, and creatinine levels were elevated in mice treated with LCT alone compared with the other tested groups (P<.05). LCT-induced oxidative damage caused a significant decrease in GSH levels and a significant rise in MDA levels of liver and kidney tissues. LCT alone-treated mice presented higher frequencies (P<.05) of MNs, CAs, and abnormal metaphases compared with the controls; moreover, the mitotic index was lower than in controls (P<.05). Oral treatment with RJ significantly ameliorated the indices of hepatotoxicity, nephrotoxicity, lipid peroxidation, and genotoxicity induced by LCT. Both doses of RJ tested provided significant protection against LCT-induced toxicity, and its strongest effect was observed at the dose level of 250 mg/kg of body weight. In vivo results suggest that RJ is a potent antioxidant against LCT-induced toxicity, and its protective effect is dose dependent.

    To evaluate the effects of oral estradiol and transdermal 17β-estradiol on serum concentrations of IGF1 and its binding proteins in women with hypopituitarism. Prospective, comparative study. Eleven patients with hypopituitarism were randomly allocated to receive 2 mg oral estradiol (n=6) or 50 μg/day of transdermal 17β-estradiol (n=5) for 3 months. The oral estrogen group showed a significant reduction in IGF1 levels (mean: 42.7%±41.4, P=0.046); no difference was observed in the transdermal estrogen group. There was a significant increase in IGFBP1 levels (mean: 170.2%±230.9, P=0.028) in the oral group, but not in the transdermal group. There was no significant difference within either group in terms of median IGFBP3 levels. In relation to lipid profiles, there was a significant increase in mean high-density lipoprotein cholesterol levels in the oral group after 3 months of treatment, (27.8±9.3, P=0.003). We found no differences in the anthropometric measurements, blood pressure, heart rate, glucose, insulin, C-peptide, or the homeostasis model assessment index after treatment. Our preliminary data indicate that different estrogen administration routes can influence IGF1 and IGFBP1 levels. These findings in patients with hypopituitarism have an impact on their response to treatment with GH, since patients receiving oral estrogen require increased GH dosage. These results suggest that oral estrogens may reduce the beneficial effects of GH replacement on fat and protein metabolism, body composition, and quality of life.

    Polycystic ovary syndrome (PCOS) is a complex syndrome showing clinical features of an endocrine/metabolic disorder, including hyperinsulinemia and hyperandrogenism. Polyunsaturated fatty acids (PUFAs) and their derivatives, both tightly linked to PCOS and obesity, play important roles in inflammation and reproduction. This study aimed to investigate serum lipid profiles in newly diagnosed patients with PCOS using lipidomics and correlate these features with the hyperinsulinemia and hyperandrogenism associated with PCOS and obesity. Thirty-two newly diagnosed women with PCOS and 34 controls were divided into obese and lean subgroups. A PCOS rat model was used to validate results of the human studies. Serum lipid profiles, including phospholipids, free fatty acids (FFAs), and bioactive lipids, were analyzed using gas chromatography-mass spectrometry (MS) and liquid chromatography-MS. Elevation in phosphatidylcholine and a concomitant decrease in lysophospholipid were found in obese patients with PCOS vs lean controls. Obese patients with PCOS had decreased PUFA levels and increased levels of long-chain saturated fatty acids vs lean controls. Serum bioactive lipids downstream of arachidonic acid were increased in obese controls, but reduced in both obese and lean patients with PCOS vs their respective controls. Patients with PCOS showed abnormal levels of phosphatidylcholine, FFAs, and PUFA metabolites. Circulating insulin and androgens may have opposing effects on lipid profiles in patients with PCOS, particularly on the bioactive lipid metabolites derived from PUFAs. These clinical observations warrant further studies of the molecular mechanisms and clinical implications of PCOS and obesity. Copyright © 2017 by the Endocrine Society

    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.

A pharmacoeconomic evaluation was performed within the Chinese intensive care unit (ICU setting. This assessed whether the additional acquisition cost of PN with omega-3 fatty-acid-enriched lipid emulsion (SMOFlipid vs standard PN was offset by improved clinical outcomes that can reduce subsequent costs. Materials and methods: A pharmacoeconomic discrete event simulation model was developed, based on an update to efficacy data from a previous international meta-analysis, with China-specific clinical and economic input parameters. Sensitivity analyses were undertaken to assess the effects of uncertainty around input parameters. Results: The model predicted that PN with an omega-3 fatty-acid-enriched lipid emulsion was more effective and less costly than PN with standard lipid emulsions for Chinese ICU patients, as follows: reduced length of overall hospital length of stay (19.48 vs 21.35 days, respectively, reduced length of ICU stay (5.03 vs 6.18 days, respectively, and prevention of 35.6% of nosocomial infections leading to a lower total cost per patient (¥47 189 [US $6937] vs ¥54 783 [US $8053], respectively. Additional treatment costs were offset by savings in overall hospital and ICU stay cost, and antibiotic cost, resulting in a mean cost saving of ¥7594 (US $1116 per patient. Sensitivity analyses confirmed the robustness of these findings. Conclusions: PN enriched with an omega-3 fatty-acid-containing lipid emulsion vs standard PN may be effective in reducing length of hospital and ICU stay and infectious complications in

    Plant sterol (PS)-supplemented foods are recommended to help in lowering serum LDL-cholesterol (LDL-C). Few studies have examined the efficacy of PS-enriched skimmed milk (SM) or semi-SM enriched with vegetable fat (PS-VFM). There is also insufficient information on factors predictive of LDL-C responses to PS. We examined the effects of PS-SM (0·1 % dairy fat) and PS-VFM (0·1 % dairy fat plus 1·5 % vegetable fat) on serum lipids and non-cholesterol sterols in hypercholesterolaemic individuals. In a placebo-controlled, crossover study, forty-three subjects with LDL-C>1300 mg/l were randomly assigned to three 4-week treatment periods: control SM, PS-SM and PS-VFM, with 500 ml milk with or without 3·4 g PS esters (2 g free PS). Serum concentrations of lipids and non-cholesterol sterols were measured. Compared to control, LDL-C decreased by 8·0 and 7·4 % (P synthesis and high cholesterol absorption predicted improved LDL-C responses to PS.

    Malnourished HIV-infected patients starting antiretroviral therapy (ART) are at high risk of early mortality, some of which may be attributed to altered electrolyte metabolism. We used data from a randomised controlled trial of electrolyte-enriched lipid-based nutritional supplements to assess...... that changes in serum electrolytes, largely irrespective of the starting point and the direction of change, were more strongly associated with mortality than were absolute electrolyte levels. Although K and phosphate are required for tissue deposition during recovery from malnutrition, further studies...... are needed to determine whether specific supplements exacerbate physiologically adverse shifts in electrolyte levels during nutritional rehabilitation of ill malnourished HIV patients....

    Biomarkers will play important roles in disease diagnosis, drug development, and the proper use of drugs. Blood is considered the best biofluid for biomarker research because it is easy to access and a wealth of data are available. However, previous studies revealed that several ionic metabolites showed different levels (including presence or absence) in plasma and serum. Thus, attention should be paid to selecting the best biofluid for biomarker exploration. Many lipid molecules have biological significance and thus would be candidate biomarkers. However, no comprehensive study revealing differences in lipid metabolite levels between plasma and serum has been undertaken. Furthermore, gender differences have not been reported. To clarify the difference in the levels of lipid metabolites between human plasma and serum from both genders, we performed lipid metabolomic analysis using liquid chromatography-mass spectrometry-based systems for phospholipids (PLs), lysoPLs, sphingomyelins, ceramides and oxidative fatty acids. Our results revealed that most of the lipid metabolites were present at similar levels in plasma and serum and in males and females. However, several oxidative fatty acid metabolites showed differences. Of the metabolites related to clotting processes, three showed higher levels in serum than in plasma, and three were detected only in serum. Furthermore, four metabolites were present at different levels between males and females, and two were detected only in males. Thus, attention should be paid to the selection of plasma or serum when utilizing these lipid metabolites as biomarkers.

    Roselle (Hibiscus sabdariffa L.) is a plant with antihyperlipidemic and antihypertensive effects. This study aimed to evaluate the effects of roselle calyces on the serum levels of lipids and insulin, inflammation, and oxidative stress in patients with metabolic syndrome (MetS). Forty adult patients with MetS were randomly assigned to receive either 500 mg of H. sabdariffa calyx powder or placebo once daily for 4 weeks. Systolic and diastolic blood pressures (SBP and DBP) and BMI (body mass index) as well as fasting serum levels of glucose (FPG; fasting plasma glucose), insulin, lipoproteins, triglycerides (TG), high-sensitivity C-reactive protein (hs-CRP), and malondialdehyde (MDA) were determined pre- and post-intervention and compared. H. sabdariffa significantly reduced serum TG (p=0.044) and SBP (p=0.049) compared to placebo. All other variables were not significantly affected by the interventions. Daily consumption of 500 mg of H. sabdariffa L. calyx powder can decrease SBP and serum TG in MetS patients.

    Full Text Available Objective. To compare the modifications in lipids between patients with rheumatoid arthritis (RA receiving etanercept plus methotrexate (ETA + MTX versus methotrexate (MTX and their relationship with serum levels of tumor necrosis factor-alpha (TNF-α. Methods. In an observational cohort study, we compared changes in lipid levels in patients receiving ETA + MTX versus MTX in RA. These groups were assessed at baseline and at 4 and 24 weeks, measuring clinical outcomes, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol, and TNF-α. Results. Baseline values for lipid levels were similar in both groups. HDL-C levels increased significantly only in the ETA + MTX group (from 45.5 to 50.0 mg/dL at 4 weeks, a 10.2% increase, P<0.001, and to 56.0 mg/dL at 24 weeks, a 25.1% increase, P<0.001, while other lipids underwent no significant changes. ETA + MTX also exhibited a significant increase in TNF-α (44.8 pg/mL at baseline versus 281.4 pg/mL at 24 weeks, P<0.001. The MTX group had no significant changes in lipids or TNF-α. Significant differences in HDL-C between groups were observed at 24 weeks (P=0.04 and also in TNF-α  (P=0.01. Conclusion. HDL-C levels increased significantly following treatment with ETA + MTX, without a relationship with decrease of TNF-α.

    Percutaneous liver biopsies and blood samples were obtained from 80 dairy cows in nine Michigan herds over the peripartum period. Thirty-nine cows were fed 17 g of supplemental inositol and 41 were fed a placebo. Liver biopsies were assayed for total myoinositol and triglyceride (TG) concentrations. Blood samples were assayed for serum dextran precipitable cholesterol, nonesterified fatty acids (NEFA), insulin, thyroxine (T4), free (FT4), triiodothyronine (T3) and free T3 (FT3) concentrations. Serum concentrations of insulin and the thyroid hormones decreased near parturition, with lowest concentrations occurring in the immediate postpartum period. Concentrations of T3 correlated well with T4, and the concentrations of free thyroid hormones reflected concentrations of total thyroid hormones. The percentage of hormone in the free fraction remained constant over time. Serum insulin, T3 and T4 were negatively correlated with serum NEFA and liver TG concentrations. Thyroid hormone concentrations were positively correlated with serum dextran precipitable cholesterol concentrations. Inositol supplementation was associated with reduced circulating T3 and FT3 concentrations, but not T4 and FT4 concentrations. Changes in hormone concentrations at parturition and their relationship to liver TG and serum NEFA concentrations were consistent with a metabolic adaptation by the dairy cow to the negative energy balance of early lactation.

    Controversy exists as to whether the lipid-lowering properties of kefir drink (a fermented probiotic dairy product) in animal models could be replicated in humans. To assess and compare the potential lipid-lowering effects of kefir drink with low-fat milk in a dairy-rich diet in overweight or obese premenopausal women. In this 8-week, single-center, multiarm, parallel-group, outpatient, randomized controlled trial, 75 eligible Iranian women aged 25 to 45 years were randomly allocated to kefir, milk, or control groups. Women in the control group received a weight-maintenance diet containing 2 servings/d of low-fat dairy products, whereas subjects in the milk and kefir groups received a similar diet containing 2 additional servings/d (a total of 4 servings/d) of dairy products from low-fat milk or kefir drink, respectively. At baseline and study end point, serum levels/ratios of total cholesterol (TC), low- and high-density lipoprotein cholesterol (LDLC and HDLC), triglyceride, Non-HDLC, TC/HDLC, LDLC/HDLC, and triglyceride/LDLC were measured as outcome measures. After 8 weeks, subjects in the kefir group had significantly lower serum levels/ratios of lipoproteins than those in the control group (mean between-group differences were -10.4 mg/dL, -9.7 mg/dL, -11.5 mg/dL, -0.4, and -0.3 for TC, LDLC, non-HDLC, TC/HDLC, and LDLC/HDLC, respectively; all P < .05). Similar results were observed in the milk group. However, no such significant differences were found between the kefir and milk groups. Kefir drink causes a significant yet similar improvement in serum lipid profile, compared with low-fat milk, in a dairy-rich diet in overweight or obese premenopausal women.

    Full Text Available Free radicals are involved in molecular changes and mutation and if they are not inactivated the resultant lipid peroxidation will damage all types of cellular macromolecules such as proteins, carbohydrates, lipids and nucleic acids. Natural diet containing antioxidants plays an important role in health, reproduction, performance, safety and growth in poultry. Garlic extract with a high antioxidant effect very useful against free radicals and infective agents. In this study, the effect of concentration of 0.01 and 0.02% of garlic extract in drinking water with periods of 2, 4 and 6 days a week were evaluated on lipid peroxidation. In addition to assessing the best concentration, economic aspects were also considered. So at the end of the third week, the best effect on reducing lipid peroxidation was seen in T3 which had received the concentration of 0.02% of garlic extract, two days a week.  After six weeks of trial, Group T7 which had received the concentration of 0.02% garlic extract for 6 days a week, showed the best effect on reducing lipid peroxidation. Our studies also showed that garlic extract improved mass production in all groups compared to the control group.  Considering the amount of lipid peroxidation at the end of the sixth week, herd performance in six weeks and calculating the average sale price of mass production, minus the cost of feed consumed per group, it is concluded that group T4 which received garlic extract concentration of 0.01% for 4 days a week (Saturday, Monday, Wednesday, Thursday showed the best option in view of the economic conditions.

    Lipidomics, the comprehensive measurement of lipid species in a biological system, has promising potential in biomarker discovery and disease etiology elucidation. Advances in chromatographic separation, mass spectrometric techniques, and novel substrate applications continue to expand the number of lipid species observed. The total number and type of lipid species detected in a given sample are generally indicative of the sample matrix examined (e.g., serum, plasma, cells, bacteria, tissue, etc.). Current exact mass lipid libraries are static and represent the most commonly analyzed matrices. It is common practice for users to manually curate their own lists of lipid species and adduct masses; however, this process is time-consuming. LipidPioneer, an interactive template, can be used to generate exact masses and molecular formulas of lipid species that may be encountered in the mass spectrometric analysis of lipid profiles. Over 60 lipid classes are present in the LipidPioneer template and include several unique lipid species, such as ether-linked lipids and lipid oxidation products. In the template, users can add any fatty acyl constituents without limitation in the number of carbons or degrees of unsaturation. LipidPioneer accepts naming using the lipid class level (sum composition) and the LIPID MAPS notation for fatty acyl structure level. In addition to lipid identification, user-generated lipid m/z values can be used to develop inclusion lists for targeted fragmentation experiments. Resulting lipid names and m/z values can be imported into software such as MZmine or Compound Discoverer to automate exact mass searching and isotopic pattern matching across experimental data.

    Metabolic syndrome (MetS) is a health problem throughout the world and is associated with cardiovascular disease and diabetes. Thus, the purpose of the present work was to evaluate the effects of a dietary pattern (DP; soy protein, nopal, chia seed, and oat) on the biochemical variables of MetS, the AUC for glucose and insulin, glucose intolerance (GI), the relationship of the presence of certain polymorphisms related to MetS, and the response to the DP. In this randomized trial, the participants consumed their habitual diet but reduced by 500 kcal for 2 wk. They were then assigned to the placebo (P; n = 35) or DP (n = 32) group and consumed the reduced energy diet plus the P or DP beverage (235 kcal) minus the energy provided by these for 2 mo. All participants had decreases in body weight (BW), BMI, and waist circumference during the 2-mo treatment (P < 0.0001); however, only the DP group had decreases in serum TG, C-reactive protein (CRP), and AUC for insulin and GI after a glucose tolerance test. Interestingly, participants in the DP group with MetS and the ABCA1 R230C variant had a greater decrease in BW and an increase in serum adiponectin concentration after 2 mo of dietary treatment than those with the ABCA1 R230R variant. The results from this study suggest that lifestyle interventions involving specific DP for the treatment of MetS could be more effective if local foods and genetic variations of the population are considered.

    Background Although complex multivitamin products are widely used as dietary supplements to maintain health or as special medical food in certain diseases, the effects of these products were not investigated in hyperlipidemia which is a major risk factor for cardiovascular diseases. Therefore, here we investigated if a preparation developed for human use containing different vitamins, minerals and trace elements enriched with phytosterol (VMTP) affects the severity of experimental hyperlipidemia as well as myocardial ischemia/reperfusion injury. Methods Male Wistar rats were fed a normal or cholesterol-enriched (2% cholesterol + 0.25% cholate) diet for 12 weeks to induce hyperlipidemia. From week 8, rats in both groups were fed with a VMTP preparation or placebo for 4 weeks. Serum triglyceride and cholesterol levels were measured at week 0, 8 and 12. At week 12, hearts were isolated, perfused according to Langendorff and subjected to a 30-min coronary occlusion followed by 120 min reperfusion to measure infarct size. Results At week 8, cholesterol-fed rats showed significantly higher serum cholesterol level as compared to normal animals, however, serum triglyceride level did not change. VMTP treatment significantly decreased serum cholesterol level in the hyperlipidemic group by week 12 without affecting triglyceride levels. However, VMTP did not show beneficial effect on infarct size. The inflammatory marker hs-CRP and the antioxidant uric acid were also not significantly different. Conclusions This is the first demonstration that treatment of hyperlipidemic subjects with a VMTP preparation reduces serum cholesterol, the major risk factor for cardiovascular disease; however, it does not provide cardioprotection.

    A survey was conducted on 110 normal Japanese adults (55 men and 55 women) to determine their caloric intake, dietary fat content and its origin (animal, plant, or marine). In addition, their blood lipid levels and fatty acid compositions were examined. Men in their 30s-50s consumed 2,600-2,800 calories and 60 g of fats, while women in the same age range consumed 2,000-2,200 calories and 52-58 g of fats. In both sexes, caloric, fat, and cholesterol intakes were lower for those in their 60s but protein and crude fiber consumption remained generally unchanged. When the dietary fats were classified according to origin, men and women in their 30s were found to consume less oil of marine origin. This appeared to be the result of a western style diet for Japanese adults in their 30s. Compared with men, women exhibited lower blood lipid levels. As age increased, the total cholesterol level of the blood rose in women. Thus the blood lipid level was generally equal in the two groups in their 60s. There was a positive correlation between the blood eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels and dietary consumption of fish oil. The marine/plant lipid ratio was positively correlated with the blood EPA/arachidonic acid ratio. Therefore, it was believed that the origin of the dietary fats consumed is a factor in determining the blood fatty acid profile. The linoleic acid (18:2), arachidonic acid (20:4), and 18:2 + 20:4 contents were negatively correlated to the total cholesterol level in the blood but positively correlated to the HDL-cholesterol level. Polyunsaturated fatty acids (18:2 + 20:4 + 20:5 + 22:6) were negatively correlated with the blood triglyceride level. From the findings presented above, we concluded that dietary fats not derived from animal sources should be classified into fish and vegetable oils to evaluate their dietary significance. We also noted that Japanese in their 30s consume less fish oil, indicating the western trend in their

    Full Text Available Background: Preeclampsia is the most common and major medical complication of pregnancy with a high incidence of maternal and foetal morbidity and mortality. During pregnancy abnormally increased lipid peroxidation and free radical formation as well as significantly decreased antioxidants production in maternal blood may lead to pathogenesis of preeclampsia. So, we designed this study as little information is known about lipid peroxidation and antioxidant level in preeclampsia. Objectives: To assess the serum malondialdehyde (MDA level as a lipid peroxidation product and vitamin E (antioxidant level in women with preeclampsia as well as in normal pregnancy and to compare the values. Materials and Methods: The study was conducted on 60 women aged from 25 to 35 years in the department of Biochemistry, Budi Kemuliaan Maternity Hospital (BKMH in Jakarta during the period April to July 2004. Twenty were normal pregnant women and 20 were preeclamptic patients. For comparison age matched 20 apparently healthy nonpregnant women were included in the study. The study subjects were selected from outpatient department (OPD of Obstetrics and Gynaecology of BKMH in Jakarta. Serum MDA (lipid peroxidation product level was measured by thiobarbituric acid reactive substances assay (TBRAS method and vitamin E was estimated spectroflurometrically. Data were analyzed by unpaired Student’s t test between the groups by using SPSS version 12. Results: The mean serum MDA levels were significantly higher in normal pregnancy and also in preeclampsia than that of nonpregnant control group women (p<0.001. Again the serum MDA levels were significantly higher in preeclampsia than that of normal pregnant women (p<0.001. The serum vitamin E levels were significantly lower in preeclampsia and also in normal pregnancy than that of nonpregnant control women (p<0.001. Moreover, the serum vitamin E levels were significantly lower in preeclampsia compared to that of normal

    Malnutrition is very common among chronically hospitalized patients, especially those in the intensive care unit (ICU). Identifying the patients at risk and providing suitable nutritional support can prevent and/or overcome malnutrition in them. Total parenteral nutrition (TPN) and partial parenteral nutrition (PPN) are two common routes to deliver nutrition to hospitalized patients. We conducted a multicenter, prospective double blind randomized controlled trial to evaluate the benefits and compare their adverse effects of each method. 97 patients were enrolled and divided into two groups based on the inclusion criteria. Serum protein, serum albumin, serum transferrin, and total lymphocyte count were measured on days 7 and 14. We did not find any statistically significant differences in clinical status or laboratory values between the two groups but there were significant improvements in measured lab values between days 7 and 14 (pnutritional status in each groups. This study shows that both TPN and PPN can be used safely in chronic ICU patients to provide nutritional support and prevent catabolic state among chronic critically ill patients. We need to develop precise selection criteria in order to choose the patients who would benefit the most from TPN and PPN. In addition, appropriate laboratory markers are needed to monitor the metabolic requirements of the patients and assess their progress.

    To evaluate the effect of non-surgical periodontal therapy on plasma lipid levels in hyperlipidemic patients with chronic periodontitis. After considering the inclusion and exclusion criteria, 30 hyperlipidemic patients with chronic periodontitis in the age group of 30-70 years, undergoing treatment in Ahmed Gasim Cardiac and Renal transplant Centre in north Sudan were recruited for the study. Patients were randomly assigned to the study and control groups. The study group received non-surgical periodontal therapy - oral hygiene instructions, scaling and root planing. The control group participants received only oral hygiene instructions. Lipid profile [total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides (TG)], C-reactive protein (CRP), and periodontal parameters [Plaque index (PI), Gingival index (GI), probing pocket depth (PD), and attachment loss (ATL)] were measured and compared at baseline and after 3 months of the respective intervention. Between-groups analysis was done using independent "t" test and within-group analysis was done using dependent "t" test. At baseline, groups were comparable based on lipid profile and periodontal parameters. After 3 months, the control group showed significant decrease in the PI and GI scores while there was no significant change in the other parameters. However, the study group showed significant decrease in the LDL and CRP levels along with a significant decrease in PD, ATL, PI, and GI scores, compared to the baseline values. Local non-surgical periodontal therapy resulted in improved periodontal health, with significant decrease in the LDL and CRP levels in hyperlipidemic patients with chronic periodontitis. Hence, local non-surgical periodontal therapy may be considered as an adjunct in the control of hyperlipidemia, along with standard care.

    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.

    This study investigated the effect of 6-week supplementation of a probiotic strain Lactobacillus salivarius UBL S22 with or without prebiotic fructo-oligosaccharide (FOS) on serum lipid profiles, immune responses, insulin sensitivity, and gut lactobacilli in 45 healthy young individuals. The patients were divided into 3 groups (15/group), that is, placebo, probiotic, and synbiotic. After 6 weeks, a significant reduction (P < .05) in total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides and increase in high-density lipoprotein cholesterol was observed in the probiotic as well as in the synbiotic group when compared to placebo; however, the results of total cholesterol and LDL-cholesterol were more pronounced in the synbiotic group. Similarly, when compared to the placebo group, the serum concentrations of inflammatory markers such as high sensitivity C-reactive protein, interleukin (IL) 6, IL-1β, and tumor necrosis factor α were significantly (P < .05) reduced in both the experimental groups, but again the reduction in the synbiotic group was more pronounced. Also, an increase (P < .05) in the fecal counts of total lactobacilli and a decrease (P < .05) in coliforms and Escherichia coli was observed in both the experimental groups after 6 weeks of ingestion. Overall, the combination of L salivarius with FOS was observed to be more beneficial than L salivarius alone, thereby advocating that such synbiotic combinations could be therapeutically exploited for improved health and quality of life. © The Author(s) 2014.

    Peel extracts from Citrus sinensis, Punica granatum, and Musa paradisiaca were investigated for their effects on tissue lipid peroxidation (LPO) and on the concentration of thyroid hormones, insulin, and glucose in male rats. In vitro inhibition of H(2)O(2)-induced LPO in red blood cells of rats by 0.25, 0.50, 1.0, and 2.0 microg/mL C. sinensis, P. granatum, and M. paradisiaca peel extracts was observed in a dose-specific manner. Maximum inhibition was observed at 0.50 microg/mL C. sinensis, 2.0 microg/mL P. granatum, and 1.0 microg/mL M. paradisiaca. In the in vivo investigation, out of four different concentrations of each peel extract, 25, 200, and 100 mg/kg C. sinensis, P. granatum, and M. paradisiaca, respectively, were found to maximally inhibit hepatic LPO. The most effective doses were further evaluated for effects on serum triiodothyronine (T(3)), thyroxine (T(4)), insulin, and glucose concentrations. C. sinensis exhibited antithyroidal, hypoglycemic, and insulin stimulatory activities, in addition to inhibition of LPO, as it significantly decreased the serum T(4) (P paradisiaca strongly inhibited the serum level of thyroid hormones (P < .01 for both T(3) and T(4)) but increased the level of glucose (P < .05). These findings reveal the hitherto unknown potential of the tested peel extracts in the regulation of thyroid function and glucose metabolism. Besides antiperoxidative activity, C. sinensis extract has antithyroidal, hypoglycemic, and insulin stimulatory properties, which suggest its potential to ameliorate both hyperthyroidism and diabetes mellitus.

    Psoriasis is a systemic inflammatory disease associated with increased cardiovascular (CV) risk and altered lipid metabolism. Tofacitinib is an oral Janus kinase inhibitor. The aim of the study was to investigate the effects of tofacitinib on traditional and nontraditional lipid parameters and CV risk markers in patients with psoriasis from a phase III study, OPT Pivotal 1. Patients with psoriasis were randomized to tofacitinib 5 or 10 mg twice daily (BID) or placebo BID. Serum samples were collected at baseline, week 4, and week 16. Analyses included serum cholesterol levels, triglycerides, lipoproteins, lipid particles, lipid-related parameters/CV risk markers, and high-density lipoprotein (HDL) function analyses. At week 16, small concurrent increases in mean low-density lipoprotein cholesterol (LDL-C) and HDL cholesterol (HDL-C) levels were observed with tofacitinib; total cholesterol/HDL-C ratio did not change. There was no significant change in the number of small dense LDL particles, which are considered to be more atherogenic than large particles, and oxidized LDL did not increase. Paraoxonase 1 activity, linked to HDL antioxidant capacity, increased, and HDL-associated serum amyloid A, which reduces the anti-atherogenic potential of HDL, decreased. HDL capacity to promote cholesterol efflux from macrophages did not change. Lecithin-cholesterol acyltransferase activity, which is associated with reverse cholesterol transport, increased. Markers of systemic inflammation, serum amyloid A and C-reactive protein, decreased with tofacitinib. While small increases in lipid levels are observed with tofacitinib treatment in patients with psoriasis, effects on selected lipid-related parameters and other circulating CV risk biomarkers are not suggestive of an increased CV risk [NCT01276639].

    Knowledge of the health impact of consuming heat-treated versus raw fish fillet is limited. To investigate effects of baked or raw salmon fillet intake on lipids and n-3 PUFAs in serum and tissues, obese Zucker fa/fa rats were fed diets containing 25% of protein from baked or raw salmon fillet and 75% of protein from casein, or casein as the sole protein source (control group) for four weeks. Salmon diets had similar composition of amino and fatty acids. Growth and energy intake were similar in all groups. Amounts of lipids and n-3 PUFAs in serum, liver and skeletal muscle were similar between rats fed baked or raw salmon fillet. When compared to the control group, rats fed baked salmon had lower serum total and LDL cholesterol and higher serum triacylglycerol levels. Both raw and baked salmon groups had lower HDL cholesterol level when compared to control rats. In conclusion, baking as a preparation method does not alter protein and fat qualities of salmon fillets, and intake of baked and raw salmon fillets gave similar effects on lipids and n-3 PUFAs in serum and tissues from rats.

  6. Do abnormal serum lipid levels increase the risk of chronic low back pain? The Nord-Trøndelag 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 cases of chronic Brucella spp. infection, results of the rose bengal plate test (RBPT) and indirect enzyme-linked immunosorbent assay (ELISA) should be coherent, as reported in controlled conditions in the literature. We compared RBPT and ELISA results in 58 Alaska grizzly bears ( Ursus arctos horribilis), eight Kodiak brown bears ( Ursus arctos middendorffi), and six Alaska Peninsula brown bears ( Ursus arctos gyas). Of the 72 bears tested, 42 (58%) were ELISA positive and 53 (73%) were RBPT positive. However, the coherence between the tests was only fair (K=0.37, SE=0.11), suggesting that either the serologic results were not compatible with Brucella spp. infection or that there was a technical problem with the tests. To address a potential technical problem, we performed a 30-min chloroform/centrifugation cleanup. Following cleanup, the ELISA identified 43 positives (59%) and the RBPT identified 47 (65%), and the coherence between the tests was much improved (K=0.80, SE=0.07). We recommend cleaning wildlife sera with a high lipid content before performing RBPT and performing RBPT and ELISA in parallel to assess coherence. Our results suggest that Alaskan brown bears have been exposed to Brucella spp.

    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, streptozotocin (55 mg/kg, IP was injected to induce diabetes. The treatment groups received leptin (0.1 mg/kg SC for 10 days, and then, blood samples were taken from the orbital sinus for laboratory evaluations. Results: Leptin resulted in a significant weight loss in both sexes (P

    Combining foods with recognized cholesterol-lowering properties (dietary portfolio) has proven highly effective in lowering serum cholesterol under metabolically controlled conditions. To assess the effect of a dietary portfolio administered at 2 levels of intensity on percentage change in low-density lipoprotein cholesterol (LDL-C) among participants following self-selected diets. A parallel-design study of 351 participants with hyperlipidemia from 4 participating academic centers across Canada (Quebec City, Toronto, Winnipeg, and Vancouver) randomized between June 25, 2007, and February 19, 2009, to 1 of 3 treatments lasting 6 months. Participants received dietary advice for 6 months on either a low-saturated fat therapeutic diet (control) or a dietary portfolio, for which counseling was delivered at different frequencies, that emphasized dietary incorporation of plant sterols, soy protein, viscous fibers, and nuts. Routine dietary portfolio involved 2 clinic visits over 6 months and intensive dietary portfolio involved 7 clinic visits over 6 months. Percentage change in serum LDL-C. In the modified intention-to-treat analysis of 345 participants, the overall attrition rate was not significantly different between treatments (18% for intensive dietary portfolio, 23% for routine dietary portfolio, and 26% for control; Fisher exact test, P = .33). The LDL-C reductions from an overall mean of 171 mg/dL (95% confidence interval [CI], 168-174 mg/dL) were -13.8% (95% CI, -17.2% to -10.3%; P portfolio; -13.1% (95% CI, -16.7% to -9.5%; P portfolio; and -3.0% (95% CI, -6.1% to 0.1%; P = .06) or -8 mg/dL (95% CI, -13 to -3 mg/dL; P = .002) for the control diet. Percentage LDL-C reductions for each dietary portfolio were significantly more than the control diet (P portfolio interventions did not differ significantly (P = .66). Among participants randomized to one of the dietary portfolio interventions, percentage reduction in LDL-C on the dietary portfolio was associated

    2015-02-01

    Full Text Available Background Coronary artery disease (CAD is one of the major causes of death worldwide. There is a direct relationship between increased levels of blood cholesterol, triglycerides (TG, low density lipoproteins (LDL, high density lipoproteins (HDL, nitric oxide (NO, and high sensitivity C-reactive protein (hs-CRP and the CAD. Walnut may reduce these factors and consequently decrease the risk of CAD. Objectives The aim of this study was to evaluate the effect of walnut consumption on TG, LDL, cholesterol, HDL, NO, and hs-CRP in patients with CAD and healthy people. Patients and Methods In this randomized crossover clinical trial, 70 patients with CAD were divided into two groups: case and control groups. The patients were given 40 g walnuts daily for 4 weeks. After 4 weeks, the TG, LDL, cholesterol, HDL, NO and hs-CRP levels were measured. The experiment was also carried out on healthy people (3 groups with normal range of lipid. The LDL, HDL, cholesterol, and hs-CRP levels were measured using commercially available kits. The nitric oxide level was measured using the Griess reaction method. Results The cholesterol and LDL levels decreased significantly from 202.43 to 187.46 and 123.80 to 108.63 mmol/L (7.9% and 13.9 %, respectively in healthy subjects after the treatment (P < 0.01. In the experimental group, there was no significant difference in cholesterol (P = 0.110 and LDL levels (P = 0.176 before and after the treatment. Moreover, no significant difference was observed in other parameters between the two groups. Conclusions The walnut consumption did not affect cholesterol levels in patients with CAD; however, it might be administered as an agent for reducing the cholesterol, which is one of the risk factors associated with CAD.

    Full Text Available Satureja khuzestanica is an endemic plant of Iran that is widely distributed in the Southern part of the country. It has antioxidant properties and thus it seems to be useful in diseases related to oxidative stress such as diabetes and hyperlipidemia. The present study investigates the effect of S. khuzestanica supplement in metabolic parameters of hyperlipidemic patients with type 2 diabetes mellitus. Twenty-one hyperlipidemic patients with type 2 diabetes mellitus were randomized in a double blind, placebo controlled clinical trial to receive either S. khuzestanica (tablets contain 250 mg dried leaves or placebo once a day for 60 days. Blood samples were obtained at baseline and at the end of the study. Samples were analyzed for levels of glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, creatinine, thiobarbituric acid reactive substances (TBARS as marker of lipid peroxidation and ferric reducing ability (total antioxidant power, TAP. Treatment of patients by S. khuzestanica for 60 days induced significant decrease in total cholesterol (P = 0.008 and LDL-cholesterol (P = 0.03 while increased HDL-cholesterol (P = 0.02 and TAP (P = 0.007 in comparison with the baseline values. S. khuzestanica did not alter blood glucose, triglyceride, creatinin and TBARS levels. In comparison with baseline values, no significant change was observed in blood glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, creatinine, TBARS and TAP in placebo-treated group. Usage of S. khuzestanica as a supplement to drug regimen of diabetic type 2 patients with hyperlipidemia is recommended.

    Full Text Available OBJETIVO: Determinar numa população de recém-nascidos de uma cidade do sul do Brasil as concentrações de lípides séricos e apolipoproteína B (apo-B em neonatos normais a termo e pré-termo, analisando-se a influência da idade gestacional e do peso ao nascimento. MÉTODOS: Foram estudados 212 neonatos de ambos os sexos, deles, 142 a termo (>37 semanas de gestação e 70 neonatos pré-termo (OBJECTIVE: To determine the concentrations of serum lipids and apolipoprotein B (apo-B in a population of normal full-term and preterm newborns in a city in Southern Brazil, and assess the impact of gestational age and birth weight on these values. METHODS: Two hundred and twelve newborns of both genders were studied, 142 of whom were full-term (>37 weeks of gestation and 70 preterm (<37 weeks of gestation. According to their birth weights, the full-term and preterm newborns were classified as small for gestational age or appropriate for gestational age. Umbilical cord blood was collected for biochemical analysis. RESULTS: The total cholesterol, LDL-C, HDL-C and apo-B values were higher in preterm newborns (79±34, 26±6, 45±15 and 36±14 mg/dL, respectively than in full-term newborns (58±19, 20±10, 31±14 and 28±7 mg/dL, respectively; p < 0.0001. Inversely, triglyceride values were lower in preterm newborns (36±14 mg/dL than in full-term newborns (43±25 mg/dL; p < 0.0018. Gender and size at birth did not have any impact on the values of total cholesterol and fractions, triglycerides, and apo-B. CONCLUSION: Plasma concentrations of lipids and apo-B in the population of newborns studied are similar to those in newborns from other countries and continents reported in medical literature and, as expected, are markedly lower than the values mentioned in literature for infants over two years of age. Fetal maturity has an impact on the concentration of lipids in newborns, but birth weight does not have any effect on these parameters.

    Full Text Available Abstract Background Obesity, type 2 diabetes mellitus (T2D and unhealthy blood lipid profile are strongly associated with the risk of developing cardiovascular disease (CVD. We examined whether blood lipid changes with short term administration of the weight lowering drug, sibutramine and lifestyle modification in obese and overweight high-risk patients was associated with T2D status at screening. Methods The Sibutramine Cardiovascular OUTcomes (SCOUT trial included obese and overweight patients at increased risk of cardiovascular events. All patients received guidance on diet and exercise plus once-daily 10 mg sibutramine during the 6-week, single blind lead-in period. Multivariable regression models were used to investigate factors associated with changes in lipid levels during the first four weeks of treatment. Results A total of 10 742 patients received at least one dose of sibutramine during the 6-week lead-in period of SCOUT. After four weeks, patients experienced mean reductions in low density lipoprotein (LDL-C 0.19 mmol/L, high density lipoprotein (HDL-C 0.019 mmol/L, very low density lipoprotein (VLDL-C 0.08 mmol/L, total cholesterol (TC 0.31 mmol/L and triglycerides 0.24 mmol/L (p 2 decrease in BMI in patients with T2D was associated with -0.09 mmol/L in LDL-C (P Conclusion Short term weight management with sibutramine therapy in obese or overweight high-risk patients induced significant mean reductions for all lipids. Those without T2D benefited most. Patients with hyperlipidaemia and the less obese patients also had greater falls in LDL-C and TC during weight loss. The trial is registered at ClinicalTrial.gov number: NCT00234832.

    Cells depend on hugely diverse lipidomes for many functions. The actions and structural integrity of the plasma membrane and most organelles also critically depend on membranes and their lipid components. Despite the biological importance of lipids, our understanding of lipid engagement, especially the roles of lipid hydrophobic alkyl side chains, in key cellular processes is still developing. Emerging research has begun to dissect the importance of lipids in intricate events such as cell division. This review discusses how these structurally diverse biomolecules are spatially and temporally regulated during cell division, with a focus on cytokinesis. We analyze how lipids facilitate changes in cellular morphology during division and how they participate in key signaling events. We identify which cytokinesis proteins are associated with membranes, suggesting lipid interactions. More broadly, we highlight key unaddressed questions in lipid cell biology and techniques, including mass spectrometry, advanced imaging, and chemical biology, which will help us gain insights into the functional roles of lipids.

    Background Investigators measuring exposure biomarkers in urine typically adjust for creatinine to account for dilution-dependent sample variation in urine concentrations. Similarly, it is standard to adjust for serum lipids when measuring lipophilic chemicals in serum. However, there is controversy regarding the best approach, and existing methods may not effectively correct for measurement error. Objectives We compared adjustment methods, including novel approaches, using simulated case–control data. Methods Using a directed acyclic graph framework, we defined six causal scenarios for epidemiologic studies of environmental chemicals measured in urine or serum. The scenarios include variables known to influence creatinine (e.g., age and hydration) or serum lipid levels (e.g., body mass index and recent fat intake). Over a range of true effect sizes, we analyzed each scenario using seven adjustment approaches and estimated the corresponding bias and confidence interval coverage across 1,000 simulated studies. Results For urinary biomarker measurements, our novel method, which incorporates both covariate-adjusted standardization and the inclusion of creatinine as a covariate in the regression model, had low bias and possessed 95% confidence interval coverage of nearly 95% for most simulated scenarios. For serum biomarker measurements, a similar approach involving standardization plus serum lipid level adjustment generally performed well. Conclusions To control measurement error bias caused by variations in serum lipids or by urinary diluteness, we recommend improved methods for standardizing exposure concentrations across individuals.

    Stretching DNA in nanochannels is a useful tool for direct, visual studies of genomic DNA at the single molecule level. To facilitate the study of the interaction of linear DNA with proteins in nanochannels, we have implemented a highly effective passivation scheme based on lipid bilayers. We demonstrate virtually complete long-term passivation of nanochannel surfaces to a range of relevant reagents, including streptavidin-coated quantum dots, RecA proteins, and RecA–DNA complexes. We show that the performance of the lipid bilayer is significantly better than that of standard bovine serum albumin-based passivation. Finally, we show how the passivated devices allow us to monitor single DNA cleavage events during enzymatic degradation by DNase I. We expect that our approach will open up for detailed, systematic studies of a wide range of protein–DNA interactions with high spatial and temporal resolution. PMID:22432814

    Full Text Available Background: Weight loss and decreasing the Body fat percentage (BF% is motivated to optimize performance. In order to achieve these, many supplements are used by athletes, however the possible negative or synergic effects have not been fully described in the literature, specifically in humans. The present study was conducted to investigate the co-administration effects of two common used supplements in body weight and BF% management to recommend athletes for safe weight and BF% reduction. Materials and Methods: In the present double-blind, randomized, parallel, placebo-controlled study, the effect of six-week co-administration of caffeine and carnitine was determined on changes in body weight (BW, BF%, serum leptin concentration and lipid profile (triglyceride, HDL Cholesterol, LDL Cholesterol and Total Cholesterol, fasting blood glucose (FBG, and free fatty acid (FFA changes. Twenty eight male teen soccer players  from Ahvaz-Iran, were divided in three groups (group CafPlc, caffeine (6 mg/kg/day + dextrose; group CafCar, caffeine (6 mg/kg/day + carnitine (2g; and group Plc, dextrose. Results: Caffeine-carnitine had a lowering effect on BW (P=0.02 and BF% (P=0.03, compared to caffeine alone and placebo in male teen soccer players (mean age of 16.92 ± 0.76 years. TG was significantly decreased in CafCar (P=0.04. FFA levels were increased in CafCar (P=0.04 and there was significant differences between CafCar and Plc groups (P=0.01. FBG was increased in both CafPlc and CafCar (P=0.01 and P=0.02, respectively, with no significant differences between groups. Conclusion: The synergistic effect of caffeine-carnitine might be suggested to decrease the BF% and BW, besides it may prevent the increment of FFA levels; however it should be prescribed cautiously since it increased FBG levels.

    Background Reservosomes are lysosome-related organelles found in Trypanosoma cruzi epimastigotes. They represent the last step in epimastigote endocytic route, accumulating a set of proteins and enzymes related to protein digestion and lipid metabolism. The reservosome matrix contains planar membranes, vesicles and lipid inclusions. Some of the latter may assume rectangular or sword-shaped crystalloid forms surrounded by a phospholipid monolayer, resembling the cholesterol crystals in foam cells. Methodology/Principal Findings Using Nile Red fluorimetry and fluorescence microscopy, as well as electron microscopy, we have established a direct correlation between serum concentration in culture medium and the presence of crystalloid lipid inclusions. Starting from a reservosome purified fraction, we have developed a fractionation protocol to isolate lipid inclusions. Gas-chromatography mass-spectrometry (GC-MS) analysis revealed that lipid inclusions are composed mainly by cholesterol and cholesterol esters. Moreover, when the parasites with crystalloid lipid-loaded reservosomes were maintained in serum free medium for 48 hours the inclusions disappeared almost completely, including the sword shaped ones. Conclusions/Significance Taken together, our results suggest that epimastigote forms of T. cruzi store high amounts of neutral lipids from extracellular medium, mostly cholesterol or cholesterol esters inside reservosomes. Interestingly, the parasites are able to disassemble the reservosome cholesterol crystalloid inclusions when submitted to serum starvation. PMID:21818313

    Urine- and serum-based biomarkers are useful for assessing individuals' exposure to environmental factors. However, variations in urinary creatinine (a measure of dilution) or serum lipid levels, if not adequately corrected for, can directly impact biomarker concentrations and bias exposure-disease association measures. Recent methodological literature has considered the complex relationships between creatinine or serum lipid levels, exposure biomarkers, outcomes, and other potentially relevant factors using directed acyclic graphs and simulation studies. The optimal measures of urinary dilution and serum lipids have also been investigated. Existing evidence supports the use of covariate-adjusted standardization plus creatinine adjustment for urinary biomarkers and standardization plus serum lipid adjustment for lipophilic, serum-based biomarkers. It is unclear which urinary dilution measure is best, but all serum lipid measures performed similarly. Future research should assess methods for pooled biomarkers and for studying diseases and exposures that affect creatinine or serum lipids directly.

    density lipoprotein-cholesterol (LDL-C and high density lipoproteins (HDL-C concentration in the population of the metropolitan area of São Paulo, Brazil. METHODS: Data on food frequency consumption (FFC, serum lipids, and other covariates were available for a representative sample of 1,045 adults. A 12-month retrospective food frequency questionnaire was used. FFC was assessed using scores of consumption, which was obtained by grouping food according to their composition into two large groups: score I (known as risk food for cardiovascular diseases and score II (known as healthy food. The association between the scores and serum blood lipoprotein levels among the study population was analyzed through multiple linear regression analyses. Modeling step-wise techniques were used to enter the covariates into the linear models. RESULTS: Increasing mean levels of TOTAL-C and LDL-C were seen from the lowest through the highest quintile of score I when compared to the score II, where decreasing mean levels of TOTAL-C and LDL-C were observed from the lowest to the highest quintile. The results of the linear regression analyses between serum TOTAL-C and LDL-C levels for both FFC score I and score II, after multivariate adjusting, showed a significant positive relationship with score I and a significant and inverse relationship with score II. CONCLUSIONS: In population studies, FFC analyses through scores can be the choice method to evaluate the quality of diet and its potential effect on serum levels of TOTAL-C and LDL-C.

  10. Oxidized Lipoprotein as a Major Vessel Cell Proliferator in Oxidized Human Serum.

    Yoshiro Saito

    Full Text Available Oxidative stress is correlated with the incidence of several diseases such as atherosclerosis and cancer, and oxidized biomolecules have been determined as biomarkers of oxidative stress; however, the detailed molecular relationship between generated oxidation products and the promotion of diseases has not been fully elucidated. In the present study, to clarify the role of serum oxidation products in vessel cell proliferation, which is related to the incidence of atherosclerosis and cancer, the major vessel cell proliferator in oxidized human serum was investigated. Oxidized human serum was prepared by free radical exposure, separated using gel chromatography, and then each fraction was added to several kinds of vessel cells including endothelial cells and smooth muscle cells. It was found that a high molecular weight fraction in oxidized human serum specifically induced vessel cell proliferation. Oxidized lipids were contained in this high molecular weight fraction, while cell proliferation activity was not observed in oxidized lipoprotein-deficient serum. Oxidized low-density lipoproteins induced vessel cell proliferation in a concentration-dependent manner. Taken together, these results indicate that oxidized lipoproteins containing lipid oxidation products function as a major vessel cell proliferator in oxidized human serum. These findings strongly indicate the relevance of determination of oxidized lipoproteins and lipid oxidation products in the diagnosis of vessel cell proliferation-related diseases such as atherosclerosis and cancer.

    Although many preclinical studies have suggested the possible linkage between dyslipidemia and cerebral amyloid deposition, the association between serum lipid measures and cerebral amyloid-beta (Aβ) deposition in human brain is still poorly known. We aimed to investigate the association in cognitively normal (CN) elderly individuals. Cross-sectional study. University hospital dementia clinic. 59 CN elderly. The study measures included comprehensive clinical and neuropsychological assessment based on the CERAD protocol, magnetic resonance imaging and (11)C-labelled Pittsburgh Compound B positron emission tomography scans, and quantification for serum lipid biomarkers. Multiple linear regression analyses showed that a higher serum triglycerides level was associated with heavier global cerebral Aβ deposition even after controlling age, sex, and apolipoprotein E ε4 genotype. Serum apolipoprotein B also showed significant positive association with global cerebral Aβ deposition, but the significance disappeared after controlling serum triglycerides level. No association was found between other lipid measures and global cerebral Aβ deposition. The findings suggest that serum triglycerides are closely associated with cerebral amyloidosis, although population-based prospective studies are needed to provide further evidence of the causative effect of triglycerides on cerebral amyloidosis.

    Full Text Available Background: Lichen planus (LP, a T-cell-mediated inflammatory disorder, wherein inflammation produces lipid metabolism disturbances, is linked to increase in cardiovascular (CV risk with dyslipidemia. Increased reactive oxygen species and lipid peroxides have also been implicated in its pathogenesis. Aim and Objective: The aim of the study was to evaluate the status on lipid disturbances, oxidative stress, and inflammation in LP patients. Materials and Methods: The study was initiated after obtaining Institutional Ethics Committee permission and written informed consent from participants. The study included 125 patients (74 LP patients and 51 age and sex-matched controls visiting the outpatient clinic in the dermatology department of our hospital. Variables analyzed included lipid profile, C-reactive protein (CRP, malondialdehyde (MDA, and catalase (CAT activity. Results: Analysis of lipid parameters revealed significantly higher levels of total cholesterol (TC, triglycerides, and low-density lipoprotein cholesterol (LDL-C along with decreased levels of high-density lipoprotein cholesterol (HDL-C in LP patients as compared to their respective controls. LP patients also presented with a significantly higher atherogenic index that is, (TC/HDL-C and LDL-C/HDL-C ratios than the controls. A significant increase in CRP levels was observed among the LP patients. There was a statistically significant increase in the serum levels of the lipid peroxidation product, MDA and a statistically significant decrease in CAT activity in LP patients as compared to their respective controls. A statistically significant positive correlation (r = 0.96 was observed between serum MDA levels and duration of LP whereas a significantly negative correlation (r = −0.76 was seen between CAT activity and LP duration. Conclusion: Chronic inflammation in patients with LP may explain the association with dyslipidemia and CV risk. Our findings also suggest that an increase in

    2016-08-17

    Protein lipidation is one of the major post-translational modifications (PTM) of proteins. The attachment of the lipid moiety frequently determines the localization and the function of the lipoproteins. Lipidated proteins participate in many essential biological processes in eukaryotic cells, including vesicular trafficking, signal transduction, and regulation of the immune response. Malfunction of these cellular processes usually leads to various diseases such as cancer. Understanding the mechanism of cellular signaling and identifying the protein-protein and protein-lipid interactions in which the lipoproteins are involved is a crucial task. To achieve these goals, fully functional lipidated proteins are required. However, access to lipoproteins by means of standard expression is often rather limited. Therefore, semisynthetic methods, involving the synthesis of lipidated peptides and their subsequent chemoselective ligation to yield full-length lipoproteins, were developed. In this Review we summarize the commonly used methods for lipoprotein synthesis and the development of the corresponding chemoselective ligation techniques. Several key studies involving full-length semisynthetic lipidated Ras, Rheb, and LC3 proteins are presented.

    ♦ Background: The longitudinal trends of lipid parameters and the impact of biocompatible peritoneal dialysis (PD) solutions on these levels remain to be fully defined. The present study aimed to a) evaluate the influence of neutral pH, low glucose degradation product (GDP) PD solutions on serum lipid parameters, and b) explore the capacity of lipid parameters (total cholesterol [TC], triglyceride [TG], high d
