    Full Text Available Background &Objective: Resistin is an important adipokin, secreted from adipocytes and causes insulin resistance. Gestational diabetes (GDM is characterized by insulin resistance in insulin target tissues. The goal of this research was to investigate whether there is a relationship among resistin and various clinical and metabolic parameters in GDM.Materials & Methods: 76 pregnant women who got the diagnosis of GDM were enrolled as the study group. 70 gestational age-matched pregnant women with normal glucose tolerance were recruited as the control group of the study. Serum resistin concentration, in addition to various metabolic and biochemical parameters, were measured in two groups.Results: Plasma resistin was not significantly different in GDM patients and subjects with normal glucose tolerance. Correlation analysis revealed that LDL cholesterol, total cholesterol and triglyceride were positively correlated with plasma resistin (P < 0.004, 0.01, and 0.02, respectively.Conclusion: Plasma resistin is correlated with insulin resistance, high serum LDL cholesterol, total cholesterol and TG in the Iranian GDM patients.

    Full Text Available Background & Objectives: There are limited number of studies conducted on the correlation between Glycemic index and Glycemic load of a food program and metabolic factors such as blood lipids in Asian countries including Iran. Therefore, this study aimed at analyzing the correlation between Glycemic index and Glycemic load of Iranian food program and blood lipids. Materials & Methods: The subjects were 95 women working in Ahvaz University of Medical Sciences in the range of 20 to 55 years old. Glycemic index and Glycemic load of the food program was analyzed with 24-hour food recall questionnaires (4-6 recall. For calculating GI and GL, Iranian food GI tables, and also, international GI and GL table were used. The levels of blood lipids including HDL cholesterol, total cholesterol, and triglycerides of the blood were measured and the level of LDL Cholesterol was calculated using Friedewald formula. Also, Anthropometric measurements were done using standard methods. Resulst: The mean age of subjects in this study was 36 years. GI mean was 72.1 and GL mean was 153.2. In this study, there was no significant relation between HDL cholesterol, LDL cholesterol, total cholesterol and Blood TG with Glycemic index and Glycemic load of food program. Conclusion: Unlike findings of west and Asian countries, both dietary GI and GL were not correlated with metabolic factors including blood lipid levels in this study , underreporting of individuals may influence the results of the study.

    The incidence of chronic pancreatitis (CP) is increasing, and dyslipidemia severely affects the health of middle-aged and elderly people. We investigated the association between blood lipid levels and CP. The serum lipid metabolic indices of 48 patients with CP (CP group) were summarized retrospectively. The physical examination results of 40 randomly selected healthy individuals were used as the normal control (NC) group. Statistical analyses of the blood lipid data were performed between the 2 groups using the case-control study method. High-density lipoprotein-cholesterol (HDL-c) levels decreased and fasting blood glucose (GLU) levels increased in the CP group compared with those in the NC group (P<0.01). Pearson correlation analysis results showed that serum amylase (AMY) was positively correlated with low-density lipoprotein-cholesterol (LDL-c; r=0.414, P<0.05), and urine AMY (UAMY) was positively correlated with total cholesterol (TC; r=0.614, P<0.01) and LDL-c (r=0.678, P<0.01). A binary logistic regression analysis showed that GLU (odds ratio [OR], 5.052; P<0.01) and TC (OR, 1.074; P<0.01) may be risk factors for CP, whereas HDL-c may be a CP protective factor (OR, 0.833; P<0.01). The HDL-c levels decreased and GLU levels increased in the CP group compared with those in the NC group; AMY was positively correlated with LDL-c and UAMY was positively correlated with TC and LDL-c; GLU and TC may be risk factors for CP; and HDL-c may be a CP protective factor. This may be the first time that such results have been reported. These findings will contribute to primary prevention and control of CP progression.

    Full Text Available Abstract Background Omega-3 and -6 polyunsaturated fatty acids (LCPUFA, are important for good health conditions. They are present in membrane phospholipids. The ratio of total n-6:n-3 LCPUFA and arachidonic acid:eicosapentaenoic acid (AA and EPA, should not exceed 5:1. Increased intake of n-6 and decreased consumption of n-3 has resulted in much higher, ca 10/15:1 ratio in RBC fatty acids with the possible appearance of a pathological "scenario". The determination of RBC phospholipid LCPUFA contents and ratios is the method of choice for assessing fatty acid status but it is labour intensive and time consuming. Aims of the study [i] To describe and validate a rapid method, suitable for large scale population studies, for total blood fatty acid assay; [ii] to verify a possible correlation between total n-6:n-3 ratio and AA:EPA ratios in RBC phospholipids and in whole-blood total lipids, [iii] to assess usefulness of these ratio as biomarkers of LCPUFA status. Methods 1 Healthy volunteers and patients with various pathologies were recruited. 2 Fatty acid analyses by GC of methyl esters from directly derivatized whole blood total lipids and from RBC phospholipids were performed on fasting blood samples from 1432 subjects categorised according to their age, sex and any existing pathologies. AA:EPA ratio and the total n-6:n-3 ratio were determined. Results AA:EPA ratio is a more sensitive and reliable index for determining changes in total blood fatty acid and it is correlated with the ratio derived from extracted RBC phospholipids. Conclusions The described AA:EPA ratio is a simple, rapid and reliable method for determining n-3 fatty acid status.

  15. Temperature dependent heterogeneous rotational correlation in lipids

    Lipid structures exhibit complex and highly dynamic lateral structure; and changes in lipid density and fluidity are believed to play an essential role in membrane targeting and function. The dynamic structure of liquids on the molecular scale can exhibit complex transient density fluctuations. Here the lateral heterogeneity of lipid dynamics is explored in free standing lipid monolayers. As the temperature is lowered the probes exhibit increasingly broad and heterogeneous rotational correlation. This increase in heterogeneity appears to exhibit a critical onset, similar to those observed for glass forming fluids. We explore heterogeneous relaxation in in a single constituent lipid monolayer of 1, 2-dimyristoyl-sn-glycero-3-phosphocholine by measuring the rotational diffusion of a fluorescent probe (1-palmitoyl-2-[1]-sn-glycero-3-phosphocholine), which is embedded in the lipid monolayer at low labeling density. Dynamic distributions are measured using wide-field time-resolved fluorescence anisotropy. The observed relaxation exhibits a narrow, liquid-like distribution at high temperatures (τ ˜ 2.4 ns), consistent with previous experimental measures (Dadashvand et al 2014 Struct. Dyn. 1 054701, Loura and Ramalho 2007 Biochim. Biophys. Acta 1768 467-478). However, as the temperature is quenched, the distribution broadens, and we observe the appearance of a long relaxation population (τ ˜ 16.5 ns). This supports the heterogeneity observed for lipids at high packing densities, and demonstrates that the nanoscale diffusion and reorganization in lipid structures can be significantly complex, even in the simplest amorphous architectures. Dynamical heterogeneity of this form can have a significant impact on the organization, permeability and energetics of lipid membrane structures.

    Full Text Available While recent scans for genetic variation associated with human disease have been immensely successful in uncovering large numbers of loci, far fewer studies have focused on the underlying pathways of disease pathogenesis. Many loci which are associated with disease and complex phenotypes map to non-coding, regulatory regions of the genome, indicating that modulation of gene transcription plays a key role. Thus, this study generated genome-wide profiles of both genetic and transcriptional variation from the total blood extracts of over 500 randomly-selected, unrelated individuals. Using measurements of blood lipids, key players in the progression of atherosclerosis, three levels of biological information are integrated in order to investigate the interactions between circulating leukocytes and proximal lipid compounds. Pair-wise correlations between gene expression and lipid concentration indicate a prominent role for basophil granulocytes and mast cells, cell types central to powerful allergic and inflammatory responses. Network analysis of gene co-expression showed that the top associations function as part of a single, previously unknown gene module, the Lipid Leukocyte (LL module. This module replicated in T cells from an independent cohort while also displaying potential tissue specificity. Further, genetic variation driving LL module expression included the single nucleotide polymorphism (SNP most strongly associated with serum immunoglobulin E (IgE levels, a key antibody in allergy. Structural Equation Modeling (SEM indicated that LL module is at least partially reactive to blood lipid levels. Taken together, this study uncovers a gene network linking blood lipids and circulating cell types and offers insight into the hypothesis that the inflammatory response plays a prominent role in metabolism and the potential control of atherogenesis.

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

Frequent nut consumption has been found to be protective against coronary heart disease in five large epidemiological studies across two continents. A qualitative summary of the data from four of these studies found an 8.3% reduction in risk of death from coronary heart disease for each weekly serving of nuts. Over 40 dietary intervention studies have been conducted evaluating the effect of nut containing diets on blood lipids. These studies have demonstrated that intake of different kinds of nuts lower total and LDL cholesterol and the LDL: HDL ratio in healthy subjects or patients with moderate hypercholesterolaemia, even in the context of healthy diets. Nuts have a unique fatty acid profile and feature a high unsaturated to saturated fatty acid ratio, an important contributing factor to the beneficial health effects of nut consumption. Additional cardioprotective nutrients found in nuts include vegetable protein, fiber, alpha-tocopherol, folic acid, magnesium, copper, phytosterols and other phytochemicals.

    Lipid oxidation plays a role in the pathophysiology of several diseases, including diabetes. Patients with type 2 diabetes show abnormally high plasma levels of phosphatidylcholine hydroperoxide (PCOOH). However, little is known about the biochemical processes that increase plasma PCOOH in diabetes. We hypothesized that "glycated lipid moieties" may form in diabetic plasma and cause oxidative stress resulting in PCOOH formation. To evaluate this hypothesis, liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods were developed to analyze Amadori-glycated phosphatidylethanolamine (Amadori-PE, an early stage Maillard product), as well as the advanced glycation end products (AGE) carboxymethyl-PE (CM-PE) and carboxyethyl-PE (CE-PE). The product ion scan, neutral loss scanning, and multiple reaction monitoring provide useful structural and quantitative information about Amadori-PE, CM-PE, and CE-PE in diabetic plasma and erythrocytes. We found that plasma and erythrocyte Amadori-PE concentrations were significantly higher in diabetic patients (757±377 nM plasma, 2793±989 nM packed cells) than in normal subjects (165±66 nM plasma, 712±52 nM packed cells), and that Amadori-PE concentrations were positively correlated with PCOOH. By contrast, no significant differences were observed in blood AGE-PE concentrations between diabetic patients (CM-PE: 7.7±3.5 nM plasma, 528±83 nM packed cells; CE-PE: 2.5±1.1 nM plasma, 82±24 nM packed cells) and normal subjects (CM-PE: 6.6±3.1 nM plasma, 705±533 nM packed cells; CE-PE: 4.2±1.5 nM plasma, 68±16 nM packed cells). These results suggest that Amadori-PE is more prone to accumulation in the blood with diabetes than CM-PE or CE-PE. This review describes the involvement of blood lipid glycation and lipid oxidation in the development of diabetes.

    Hyperlipidemia is an important risk factor of cardio-/cerebrovascular disease, and reducing lipids has become an important project for itsclinical preventing and treating. Western medicine, with its confirmative efficacy and clear mechanism, has played an irreplaceable role. Along with the development of modern medicine, integrative medicine has gradually become a growing trend in regulating blood lipids metabolism. It not only could make up the insufficient power for Chinese medicine in lowering lipids, but also could reduce adverse reactions and economic costs brought by long-term administration of Western medicine. As a modern practitioner of Chinese medicine, we should keep clear that integrative medicine regulating blood lipids metabolism does not mean a simple combination of traditional Chinese medicine and Western medicine. We should treat it guided by systematic theories. We combine disease identification and syndrome differentiation, guide lipids lowering by integrative medicine including selecting Western drugs for blood lipids lowering, Chinese medical prescriptions for syndrome typing, and effective Chinese herbs based on modern pharmacologies.

    Although animal experiments have shown that cadmium exposure induces alterations in lipid profiles, no epidemiological study of this relationship has been performed. The objective of this study was to evaluate the association between blood cadmium concentration and blood lipid levels in Korean adults. A cross-sectional study comprising participants (n=3903) aged 20 years or older from the 2005, 2008, and 2009 Korea National Health and Nutrition Examination Surveys was conducted. Demographic characteristics and dietary intake were obtained from the participants by questionnaire, and cadmium and lipid levels were determined by analysis of blood samples. After adjusting for demographic and dietary factors, blood concentration of cadmium was positively associated with the risk of low high-density lipoprotein cholesterol (HDL-C) in a dose-dependent manner (p for trend <0.001). In addition, the odds ratios (ORs) of a high triglyceride to HDL-C ratio was significantly increased in the high blood cadmium groups [OR=1.36; 95% confidence interval (CI), 1.03-1.79 for fourth quintile and OR=1.41; 95% CI, 1.07-1.86 for fifth quintile] compared with the lowest quintile group. However, high blood cadmium was not associated with a risk of high total cholesterol, high low-density lipoprotein cholesterol, or high triglycerides. These data suggest that an increased cadmium body burden increases the risk of dyslipidemia, mainly due to the increased risk of low HDL-C and the high ratio of triglycerides to HDL-C.

    Compositional lipid microdomains (“lipid rafts”) in mammalian plasma membranes are believed to facilitate many important cellular processes. While several physically distinct scenarios predicting the presence of finite-sized microdomains in vivo have been proposed in the past, direct experimental verification or falsification of model predictions has remained elusive. Herein, we demonstrate that the combination of the spatial correlation and temporal fluctuation spectra of the lipid domains can be employed to unambiguously differentiate between the existing theoretical scenarios. Furthermore, the differentiation of the raft formation mechanisms using this methodology can be achieved by collecting data at physiologically relevant conditions without the need to tune control parameters.

  13. Lipid anti-lipid antibody responses correlate with disease activity in systemic lupus erythematosus.

    Vojislav Jovanović

    Full Text Available Systemic lupus erythematosus (SLE is a chronic autoimmune disorder characterized by broad clinical manifestations including cardiovascular and renal complications with periodic disease flares and significant morbidity and mortality. One of the main contributing factors to the pathology of SLE is the accumulation and impaired clearance of immune complexes of which the principle components are host auto-antigens and antibodies. The contribution of host lipids to the formation of these autoimmune complexes remains poorly defined. The aim of the present study was to identify and analyze candidate lipid autoantigens and their corresponding anti-lipid antibody responses in a well-defined SLE patient cohort using a combination of immunological and biophysical techniques. Disease monitoring in the SLE cohort was undertaken with serial British Isles Lupus Assessment Group (BILAG scoring. Correlations between specific lipid/anti-lipid responses were investigated as disease activity developed from active flares to quiescent during a follow up period. We report a significant negative correlation between anti-lipid antibodies for 24S-hydroxycholesterol, cardiolipin and phosphatidylserine with SLE disease activity. Taken together, these data suggest that lipid autoantigens represent a new family of biomarkers that can be employed to monitor disease activity plus the efficacy of therapeutic intervention in SLE.

    Full Text Available The reliability and stability of plasma lipid biomarkers and their association with dietary fat intake were evaluated among 48 subjects who were randomly chosen from the participants of a validation study of the population-based cohort, the Shanghai Men's Health Study (SMHS. Four spot blood samples, one taken each season, were measured for total cholesterol, triglyceride, HDL-cholesterol, and LDL-cholesterol levels. The reliability and stability of these measurements were assessed by intraclass correlation coefficients (ICC and by the correlations between a randomly chosen measurement with the mean of measurements across seasons using a bootstrap approach. The median levels for total cholesterol, triglycerides, HDL-cholesterol, and LDL-cholesterol were 177.5, 164.5, 41.0, and 102.5 (mg/dl, respectively. The ICCs of the biomarkers ranged from 0.58 (LDL-cholesterol to 0.83 (HDL-cholesterol. The correlation between randomly chosen spot measurements and the mean measurement were 0.91, 0.86, 0.93, and 0.83 for total cholesterol, triglycerides, HDL-cholesterol, and LDL-cholesterol, respectively. The correlations of lipid biomarkers with dietary fat intake and other lifestyle factors were comparable to other previous reports. In conclusion, this study suggests that measurements of lipid biomarkers from a single spot blood sample are a good representation of the average blood levels of these biomarkers in the study population and could be a useful tool for epidemiological studies.

    Objective:To investigate the correlation between the periodontal health, blood glucose, weight index and blood lipid in patients with type 2 diabetes, especially in the youth patients (aged 14-44) and the elderly patients (60 years old or above). Methods:The selected hospitalized patients with type 2 diabetes (n=229) were divided into two groups, the youth group and the senior group. The periodontal bealth and values of glycated hemoglobin (HbAlc), total cholesterol (TC),triglyceride (TG) and body-mass index (BMI) were detected. A database was established with the help of software named Epdata. The correlation between the periodontal health glycemic index, weight index and lipid level was compared with SPSS 14.0 packages between the two groups. Results:The levels of TC, TG and HbAlc, and the value of body weight were significantly different between the two groups (P < 0.001 or P < 0.05). All the above factors were associated with periodontal disease in patients with type 2 diabetes. The logistic regression analysis showed that the higher levels of HbAlc and TG, overweight and obesity were the major risk factors for periodontal disease in youth group. While the major risk factors for periodontal disease were the higher levels of TC and HbAlc in the senior group. Conclusion: For the young patients with type 2 diabetes,the poor blood glucose control, obesity and increased triglyceride are the major risk factors for periodontal disease. The best prophylactic measure for aging population to reduce the incidence of periodontal disease is to control both blood glucose and total cholesterol.%目的:探讨青年组(14~44岁)和老年组(60岁以上)2型糖尿病患者的牙周健康状况与血糖控制、体质量指数及血脂水平的关系.方法:选取2型糖尿病住院患者229例,分为青年组和老年组进行研究,检查患者的牙周情况,并于入院后所有患者取血测糖化血红蛋白(HbA1c)、总胆固醇(TC)、三酰甘油(TG

    Objective:To investigate the effects of different dietary fat and oils (differing in their degree of saturation and unsaturation) on lipid peroxidation in liver and blood of rats. Methods:The study was conducted on 50 albino rats that were randomly divided into 5 groups of 10 animals. The groups were fed on dietary butter (Group I), margarine (Group II), olive oil (Group III), sunflower oil (Group IV) and corn oil (Group V) for 7 weeks. After 12 h of diet removal, livers were excised and blood was collected to measure malondialdehyde (MDA) levels in the supernatant of liver homogenate and in blood. Blood superoxide dismutase activity (SOD), glutathione peroxidase activity (GPx), serum vitamin E and total antioxidant capacity (TAC) levels were also measured to determine the effects of fats and oils on lipid peroxidation. Results: The results indicated that no significant differences were observed in SOD activity, vitamin E and TAC levels between the five groups. However, there was significant decrease of GPx activity in groups IV and V when compared with other groups. The results indicated that feeding corn oil caused significant increases in liver and blood MDA levels as compared with other oils and fats. There were positive correlations between SOD and GPx, vitamin E and TAC as well as between GPx and TAC (r:0.743;P Conclusions:The results demonstrated that feeding oils rich in polyunsaturated fatty acids (PUFA) increases lipid peroxidation significantly and may raise the susceptibility of tissues to free radical oxidative damage.

    Transfusion of red blood cells is a very common inpatient procedure, with more than 1 in 70 people in the USA receiving a red blood cell transfusion annually. However, stored red blood cells are a non-uniform product, based upon donor-to-donor variation in red blood cell storage biology. While thousands of biological parameters change in red blood cells over storage, it has remained unclear which changes correlate with function of the red blood cells, as opposed to being co-incidental changes. In the current report, a murine model of red blood cell storage/transfusion is applied across 13 genetically distinct mouse strains and combined with high resolution metabolomics to identify metabolic changes that correlated with red blood cell circulation post storage. Oxidation in general, and peroxidation of lipids in particular, emerged as changes that correlated with extreme statistical significance, including generation of dicarboxylic acids and monohydroxy fatty acids. In addition, differences in anti-oxidant pathways known to regulate oxidative stress on lipid membranes were identified. Finally, metabolites were identified that differed at the time the blood was harvested, and predict how the red blood cells perform after storage, allowing the potential to screen donors at time of collection. Together, these findings map out a new landscape in understanding metabolic changes during red blood cell storage as they relate to red blood cell circulation.

    Monitoring toxic organochlorine (OC) compounds is an important aspect in wildlife studies, especially in protected species such as sea turtles. The goal of this study was to determine whether blood OC concentrations can predict those in adipose tissue of sea turtles. Blood offers many benefits for monitoring OCs. It can be collected nondestructively from live turtles and can be sampled repeatedly for continuous monitoring. Organochlorine concentrations in blood may better represent the exposure levels of target tissues, but blood concentrations may fluctuate more than those in fatty tissues following recent dietary exposure or lipid mobilization. Paired fat and blood samples were collected from 44 live, juvenile loggerhead sea turtles and 10 juvenile Kemp's ridley sea turtle carcasses. Organochlorines were analyzed using gas chromatography with electron capture detection and mass spectrometry. Lipid-normalized OC concentrations measured in the blood significantly correlated to levels found in the fat samples of both species. This result suggests that sea turtle blood is a suitable alternative to fatty tissues for measuring OCs because blood concentrations reasonably represent those observed in the paired fat samples. However, blood OC concentrations calculated on a wet-mass basis were significantly and inversely correlated to lipid content in the fat samples. Therefore, caution should be used when monitoring spatial or temporal trends, as OC levels may increase in the blood following mobilization of fat stores, such as during long migrations, breeding, or disease events.

    Full Text Available Introduction & Objective: Diabetic hyperglycemia is associated with increased production of Reactive Oxygen Species (ROS. ROS reacts with DNA results in products such as 8-hydroxydeoxyguanosine that excrete in urine due to DNA repair processes. This study aims to evaluate correlation between oxidative damage of DNA and protein glycation in patients with Type 1 diabetes. We measured urinary 8-OHdG level in diabetic and control group and evaluated its correlation to glycated hemoglobin (HbA1c and glycated serum protein (GSP levels. Furthermore plasma malondialdehyde (MDA level was measured as an important indicator of lipid peroxidation in diabetes.Materials & Methods: We studied 32 patients with diabetes mellitus Type 1 and compared them with 48 sex and age-matched non-diabetic controls. GSP and MDA measurement were made by colorimetric assay. Hemoglobin A1c measured by ion-exchange chromatography method and urinary 8-OHdG measurement was made by competitive in vitro enzyme-linked immunosorbent assay (ELISA.Results: In the present study urinary 8-OHdG, blood HbA1c, plasma MDA and GSP levels were significantly higher in diabetics comparing to the control subjects (P<0.05. Furthermore, we found significant correlation between urinary 8-OHdG and HbA1c (P<0.05 in diabetic group. In addition, fasting blood sugar showed significant correlation with GSP and MDA (P<0.05. However the correlation of MDA with HbA1c was not significant in diabetic patients.Conclusion: This case-control study in young diabetic patients showed that increased blood glucose and related metabolic disorders result in oxidative stress and oxidative damage to DNA and lipids. Furthermore oxidative damage to DNA correlated to glycemic control, while there was no significant correlation between lipid peroxidation and the level of HbA1c.

    Full Text Available Kimchi is a Korean fermented vegetable and has recognized as a healthy food. Some interventional studies have reported an inverse association between kimchi intake and higher lipid levels in healthy and obese people. However, kimchi intake and hypertention were still uncertain. This study is carried out to investigate whether the serum lipid profiles and blood pressure would be influenced by the amount of kimchi intake. Design for the clinical study by controlling the meal consumption and physical activity of the subjects for 7 days was approved by IRB at P Hospital (No.2011075. For the study, 100 volunteers assigned into 2 groups, low (15 g/day, n=50 and high kimchi intake group (210 g/day, n=50, temporarily stayed together at the dormitory during the 7-day experimental period. Three meals with different amount of kimchi were provided and subjects were asked to maintain the normal physical activity as usual. Significant decrease in the concentration of fasting blood glucose, TG, total-C, and LDL-C for the both group was observed after 7 days of kimchi intake regardless of amount of kimchi intake. Only FBG suppression effect was significantly different (p<0.01. Furthermore, people with hypercholesterolemia (≤19 mg/dL showed greater improvements in total cholesterol levels in high kimchi intake group. One notable finding in this study was that urinary Na excretion for the high kimchi intake group was significantly increased (p<0.05. There was no significant difference in the BP reductions by kimchi intake. Higher intake of kimchi appears to be a modest beneficial effect to lipid lowering, without any effect on blood pressure in spite of increased sodium excretion. Long-term study should be clarified whether kimchi intake associated with hypertension.

    The relationship between prolonged exercise, oxidative stress, and the protective capacity of the antioxidant defense system has been determined. Venous blood samples were removed from seven trained athletes before and up to 120 h after completion of a half-marathon for measurements of blood antioxidants, antioxidant enzymes, and indices of lipid peroxidation. Plasma creatine kinase (CK) activity, an index of muscle damage, increased (P less than 0.05) to a maximum 24 h after the race but this was not accompanied by changes in conjugated dienes and thiobarbituric acid reactive substances (TBARS), which are indices of lipid peroxidation. An increase (P less than 0.05) in plasma cholesterol concentration (4%) immediately after the race was similar to the change in plasma volume (6%). However, transient increases (P less than 0.05) immediately postrace in the plasma concentrations of uric acid (24%), vitamin A (18%), and vitamin C (34%) were only partly accounted for by the fluid shifts. The immediate postrace increases in alpha- and gamma-tocopherol did not attain statistical significance. Erythrocyte antioxidant enzyme activities were unaffected by the exercise but the alpha- and gamma-tocopherol concentrations progressively increased (P less than 0.001 and P less than 0.05, respectively) up to 48 h postrace. Paradoxically, 24 h after the race erythrocyte susceptibility to in vitro peroxidation was markedly elevated (P less than 0.01). This enhanced susceptibility to peroxidation was maintained even at 120 h postrace and did not correspond to changes in the age of the red cell population. A decrease (P less than 0.001) in total erythrocyte glutathione immediately after the half-marathon was mainly due to a reduction in the reduced form (GSH). The results show that when trained athletes run a comparatively short distance sufficient to result in some degree of muscle damage but which is insufficient to cause elevations in plasma indices of lipid peroxidation

    Transfusion-related acute lung injury (TRALI) is suggested to be a "two hit" event, resulting from priming and activation of pulmonary neutrophils. It is known that neutrophil activation may result from infusion of lysophosphatidylcholines (LysoPCs) accumulated during storage of blood components. The aim of our study was to verify whether the LysoPCs are released into the storage medium of blood components. We measured the LysoPCs concentration in the supernatants from stored apheresis platelet concentrates (PLTs), packed non-leukoreduced red blood cell concentrates (RBCs), leukoreduced red blood cell concentrates (L-RBCs), fresh frozen plasma (FFP) and donor plasma (control). Lipids were separated on high-performance thin-layer chromatography, detected by primulin spray and quantified by photodensitometric scanning. The LysoPCs concentration in donor plasma was similar to that in FFP. During storage the LysoPCs content in PLTs increased almost two-fold as compared to the fresh isolated platelets. In RBCs and L-RBCs the LysoPC level was very low or below detection limit and did not increase throughout the storage period. According to our observations bioactive LysoPCs may be considered a neutrophil-activating factor only following PLT transfusions but not RBCs transfusions.

    The parameters of blood lipid spectrum have been analyzed in 421 patients who survived cerebral stroke and transitory ischemic attacks in 2004-2008. The study included people of Khanty-Mansiysk and Khanty-Mansi autonomous okrug and watchmen. The statistical analysis did not reveal differences between mean concentrations of total cholesterol, high and low density lipoproteins and triglycerides in the settled population and in watchmen. Mean values of all parameters, with the exception of high-density lipoprotein, were higher compared to normative values. The highest frequency of deviations was found for low-density lipoproteins (63.5% of cases). The highest concentrations of total cholesterol and low-density proteins were seen in patients after transitory ischemic attacks regardless of their sex. The comparison of blood lipid spectrum parameters in different age groups revealed significant differences only for total cholesterol.

    AIM: To investigate oxidative stress and lipid peroxi-dation in hepatic steatosis and the underlying implica-tions in pathological mechanisms of non-alcoholic fatty liver disease (NAFLD).METHODS: F2-isoprostanes (iPF2α-Ⅲ) in blood and liver samples from steatotic (n = 9) and control (n = 7)rats were measured as in vivo marker of lipid peroxida-tion by a mass spectrometric approach. The lipid pro-file and endogenous antioxidant status (SOD and CAT)in the rats were also analyzed.RESULTS: Significantly higher levels of iPF2α-Ⅲ (mean3.47 vs 2.40 pmol/mg tissue, P = 0.004) and lower activities of SOD (mean 1.26 U vs 1.40 U, P < 0.001) and CAT (mean 1026.36 U/mg vs 1149.68 U/mg pro-tein, without significance) were observed in the livers of steatotic rats. Plasma total iPF2α-Ⅲ was significantly correlated with the abnormalities of blood lipids as well as alanine aminotransferase (ALT) levels in the rats with simple steatosis, whereas no similar tendencies were observed in the control rats.CONCLUSION: Enhancement of hepatic oxidative imbalance occurring at the steatotic stage of NAFLD suggests a possibility that manifestation of the local oxidative damage precedes that of systemic oxidativeimbalance. Predominant metabolic features of the in-creased lipid peroxidation further suggest a close asso-ciation of the oxidative imbalance and the dyslipidemia with functional deterioration of the steatotic liver. The findings need to be further evaluated, especially in hu-man studies.

    Full Text Available AbstractAim: Substance abuse has become a universal crisisin our modern age. Among illegal substances, opium and its derivatives have been ranked second in terms of usage after cannabis in the world. In many Asian regions, the use of opium enjoys a high social acceptance; hence, some common people and even medical practitioners believe that opium lowers blood glucose and pressure and treat dyslipidemia. How much this belief is scientifically justified? Method: The results of available studies on both humans and animals searched in different search engines up to mid-2016 were integrated (77 articles. Upon the findings we try to offer a more transparent picture of the effects of opium on the mentioned factors along with the probable underlying mechanisms of its action. Results: Taken together, a variety of evidences suggest that the consumption of opium has no scientific justification for amendment of these biochemical variables. The mechanisms proposed so far for the action of opium in the three above disorders are summarized at the end of the article. Short term effects seems to be mostly mediated through central nervous system (neural and hormonal mechanisms, but long term effects are often due to the structural and functional alterations in some body organs. Conclusion: Although opium may temporarily reduce blood pressure, but it increases blood glucose and most of blood lipids. Moreover its long term use has negative impacts and thus it aggravates diabetes, dyslipidemia and hypertension. Accordingly, it is necessary to inform societies about the potential disadvantages of unauthorized opium consumption.

    Motivated by the experimental study of Tayebi et al. [Nat. Mater. 11, 1074 (2012)] on phase separation of stacked multi-component lipid bilayers, we propose a model composed of stacked two-dimensional Ising spins. We study both its static and dynamical features using Monte Carlo simulations with Kawasaki spin exchange dynamics that conserves the order parameter. We show that at thermodynamical equilibrium, due to strong inter-layer correlations, the system forms a continuous columnar structure for any finite interaction across adjacent layers. Furthermore, the phase separation shows a faster dynamics as the inter-layer interaction is increased. This temporal behavior is mainly due to an effective deeper temperature quench because of the larger value of the critical temperature, T{sub c}, for larger inter-layer interaction. When the temperature ratio, T/T{sub c}, is kept fixed, the temporal growth exponent does not increase and even slightly decreases as a function of the increased inter-layer interaction.

    Idiopathic sudden sensorineural hearing loss (ISSHL) is a common otologic emergency whose cause is still unclear. The importance of blood lipids in the pathogenesis of ISSHL is widely reported in literature. In fact elevated levels of low density lipoprotein cholesterol (LDL), total cholesterol (TC) and apolipoprotein B (Apo-B) have been proposed as risk factors for this pathology. No correlation has been described between serum lipid parameters and the prognosis of ISSHL. Aim of the present ...

    2014-01-01

    Full Text Available Hypertension and dyslipidemia exhibit an important clinical relationship because an increase in blood lipids yields an increase in blood pressure (BP. We analyzed the associations of seven polymorphisms of genes involved in lipid metabolism (APOA5 rs3135506, APOB rs1042031, FABP2 rs1799883, LDLR rs5925, LIPC rs1800588, LPL rs328, and MTTP rs1800591 with blood pressure and lipid values in Mexican hypertensive (HT patients. A total of 160 HT patients and 160 normotensive individuals were included. Genotyping was performed through PCR-RFLP, PCR-AIRS, and sequencing. The results showed significant associations in the HT group and HT subgroups classified as normolipemic and hyperlipemic. The alleles FABP2 p.55T, LIPC −514T, and MTTP −493T were associated with elevated systolic BP. Five alleles were associated with lipids. LPL p.474X and FABP2 p.55T were associated with decreased total cholesterol and LDL-C, respectively; APOA5 p.19W with increased HDL-C; APOA5 p.19W and FABP2 p.55T with increased triglycerides; and APOB p.4181K and LDLR c.1959T with decreased triglycerides. The APOB p.E4181K polymorphism increases the risk for HT (OR = 1.85, 95% CI: 1.17–2.93; P=0.001 under the dominant model. These findings indicate that polymorphisms of lipid metabolism genes modify systolic BP and lipid levels and may be important in the development of essential hypertension and dyslipidemia in Mexican HT patients.

    Full Text Available Epidemiological studies suggest a relationship between blood lipids and immune-mediated diseases, but the nature of these associations is not well understood. We used genome-wide association studies (GWAS to investigate shared single nucleotide polymorphisms (SNPs between blood lipids and immune-mediated diseases. We analyzed data from GWAS (n~200,000 individuals, applying new False Discovery Rate (FDR methods, to investigate genetic overlap between blood lipid levels [triglycerides (TG, low density lipoproteins (LDL, high density lipoproteins (HDL] and a selection of archetypal immune-mediated diseases (Crohn's disease, ulcerative colitis, rheumatoid arthritis, type 1 diabetes, celiac disease, psoriasis and sarcoidosis. We found significant polygenic pleiotropy between the blood lipids and all the investigated immune-mediated diseases. We discovered several shared risk loci between the immune-mediated diseases and TG (n = 88, LDL (n = 87 and HDL (n = 52. Three-way analyses differentiated the pattern of pleiotropy among the immune-mediated diseases. The new pleiotropic loci increased the number of functional gene network nodes representing blood lipid loci by 40%. Pathway analyses implicated several novel shared mechanisms for immune pathogenesis and lipid biology, including glycosphingolipid synthesis (e.g. FUT2 and intestinal host-microbe interactions (e.g. ATG16L1. We demonstrate a shared genetic basis for blood lipids and immune-mediated diseases independent of environmental factors. Our findings provide novel mechanistic insights into dyslipidemia and immune-mediated diseases and may have implications for therapeutic trials involving lipid-lowering and anti-inflammatory agents.

    Objective:To observe the effect of mitiglinide combined laser photocoagulation on blood glucose, blood lipid and vascular endothelial function in diabetic retinopathy.Methods:A total of 106 patients with diabetic retinopathy treated in our hospital from January 2014 to January 2015 were selected and assigned into the separate group and combined group. Fifty-three patients in the separate group only received oral mitiginide, while other 53 patients in the combined group received oral mitiglinide and laster photocoagulation surgery. Before and after treatment, the FBG, 2hPBG, HbA1c, TC, TG, HDL-C, LDL-C, ET-1, VEGF, PEDF, ICAM-1, FMD of patients in the two groups were analyzed.Results: After treatment, the blood glucose and blood lipid indexes of patients in the two groups were improved significantly, and there was no statistical difference between the two groups. The ET-1, ICAM-1 and VEGF of patients in the two groups decreased, and the decrease of the combined group was more distinctly. The PEDF and FMD in the two groups all increased, and the combined group changed more obviously. The regression of the blood vessel and the recovery of visual acuity in the combined group were better than the separate group.Conclusions:Mitiglinide combined with laser photocoagulation can effectively improve the level of blood glucose and blood lipid, promote vascular endothelial function and inhibit the formation of retinal neovascularization so as to improve the visual acuity level.

    Full Text Available BACKGROUND: Coronary heart disease (CHD is the most common form of heart disease. Changes in lifestyle, decreased physical activity, dietary modifications etc., in indian population is considered to be the major risk factor. By 2020 it is estimated that it will be th e major cause of death in the world. High sensitivity CRP (hs - CRP test measures very small amounts of CRP in the blood and is helpful even in healthy individuals to assess their potential risk for heart ailments. The hs - CRP levels are directly proportiona l to extent source of CHD which indicates that the hs - CRP has positive correlation with the disease burden. Hence the present study was undertaken. MATERIAL AND METHODS: The study was done by taking two groups controls and cases between the ages 25 - 60 year s. Fasting blood samples were collected and analysed for estimation of triglycerides, cholesterol, LDL - cholesterol, HDL - cholesterol and hs - crp levels. RESULT: Serum levels of cholesterol, TG, LDL - C, and hs - CRP (p - value 0.0001 were significantly increased and HDL - C (p - value 0.0002 was significantly decreased in cases as compared to healthy controls. CONCLUSION: It is seen that hs - CRP level is significantly elevated in cases (MI patients than the normal controls. So the present study shows a significant a nd positive correlation with conventional lipid profile parameters.

    Full Text Available The experiment was carried out to verify if total cholesterol, HDL-cholesterol and triacylglicerol plasma levels are affected when laying hens are fed rations containing different dietary oil sources. One hundred sixty 50 week-old hens, assigned to four treatments with five replicates using 8 hens per replicate were used. The experimental period was of 84 days divided in 3 cycles of 28 days each. In the last day of each cycle, blood samples of 2 hens per replicate were randomly choose and blood samples were collected. On the other hand, blood was also collected at 7 am, 11 am and 3 pm aiming to study the daily changes of these lipids. Blood lipid parameters were not affected by different dietary oil sources (p > 0.05; however, HDL-cholesterol did change during the day, giving evidence that this lipid is indeed involved in the egg yolk formation.

    Lipid A, the active component of lipopolysaccharide (LPS), exists in the outer membrane of Gram-negative bacteria and binds to the Toll-like receptor 4 (TLR4) and MD-2 complex. On the other hand, the synthetic precursor of Escherichia coli lipid A, tetraacylated lipid IVa, is an agonist for TLR4 and MD-2 complex in murine, equine and feline cells but is an antagonist for lipid A in human cells. The aim of the study was to examine the function of canine Toll-like receptor 4 (TLR4) and MD-2 complex on canine blood mononuclear cells (BMC), by analyzing lipid A- or lipid IVa-induction of TNF-α production from these cells in order to understand canine innate immune system. After 5-h culture of canine BMC with lipid A (lipid A culture) or lipid IVa (lipid IVa culture), the TNF-α, as determined by ELISA, had increased in the supernatants of the lipid A cultures in a dose-dependent manner, whereas the TNF-α was undetectable in supernatant of lipid IVa-treated cultures. The TNF-α was statistically significantly different between the lipid A and lipid IVa cultures (100 and 1000 ng/ml). TNF-α production from canine BMC was inhibited, in a lipid IVa-dose-dependent manner, when the BMC were pre-cultured with lipid IVa for 60 min and then cultured with lipid A for 5h, while in control BMC cultures production if TNF-α was unchanged. These results indicate that the TNF-α production stimulated by lipid A was competed out by pre-exposing the BMC to lipid IVa. Thus, lipid A is an agonist for TNF-α production in canine BMC, whereas lipid IVa appears to be an antagonist against this lipid A stimulation of canine BMC.

    The efficiency of the transfection of a plasmid DNA encoding a galactosidase promoted by a series of pyridinium lipids in mixtures with other cationic lipids and neutral lipids was assessed in CHO-K1 cells. We identify key molecular parameters of the lipids in the mixture - clog P, lipid length, partial molar volume - to predict the morphology of the lipid-DNA lipoplex and then correlate these same parameters with transfection efficiency in an in vitro assay. We define a Transfection Index that provides a linear correlation with normalized transfection efficiency over a series of 90 different lipoplex compositions. We also explore the influence of the same set of molecular parameters on the cytotoxicity of the formulations.

    This study investigated the effect of the biochemical and biophysical properties of the plasma membrane as well as membrane morphology on the susceptibility of human red blood cells to the cholesterol-dependent cytolysin pneumolysin, a key virulence factor of Streptococcus pneumoniae, using single cell studies. We show a correlation between the physical properties of the membrane (bending rigidity and surface and dipole electrostatic potentials) and the susceptibility of red blood cells to pneumolysin-induced hemolysis. We demonstrate that biochemical modifications of the membrane induced by oxidative stress, lipid scrambling, and artificial cell aging modulate the cell response to the toxin. We provide evidence that the diversity of response to pneumolysin in diabetic red blood cells correlates with levels of glycated hemoglobin and that the mechanical properties of the red blood cell plasma membrane are altered in diabetes. Finally, we show that diabetic red blood cells are more resistant to pneumolysin and the related toxin perfringolysin O relative to healthy red blood cells. Taken together, these studies indicate that the diversity of cell response to pneumolysin within a population of human red blood cells is influenced by the biophysical and biochemical status of the plasma membrane and the chemical and/or oxidative stress pre-history of the cell.

    To examine the association of hyperinsulinemia with the atherogenic risk profile in children, we studied the relationships of the fasting plasma insulin level with indices of obesity (body mass index [BMI] and sum of triceps and subscapular skinfold thickness [SFT]), body fat distribution (waist to hip ratio [WHR]), serum lipid, lipoprotein, and apolipoprotein levels, and blood pressure in a case-control study of 460 Kuwaiti prepubertal obese children aged 6 to 13 years matched by age and sex to 460 prepubertal non-obese controls. Obese children were ascertained in a representative cross-sectional study of 2,400 school children. Fasting insulin levels were positively correlated (P < .001) with serum triglyceride (TG) and very-low-density lipoprotein (VLDL) cholesterol levels and negatively correlated with high-density lipoprotein (HDL) cholesterol levels. No significant associations were observed between insulin and total cholesterol (TC), cholesterol, low-density lipoprotein (LDL) or apolipoprotein A-I (apo A-I). Stronger associations of insulin levels with lipoprotein fractions were observed in obese versus non-obese controls. Obese children had a higher concentration of apo B and a lower apo A-I:B ratio (P < .001). Insulin and the insulin to glucose ratio increased with age in obese children, whereas there were slight changes in non-obese children. TG and HDL cholesterol levels and systolic blood pressure (SBP) were significantly different across insulin quartiles in boys and girls. We conclude that the fasting plasma insulin level may be used as a marker for the development of obesity-associated metabolic disorders and elevated blood pressure in children.

    Pulmonary gas uptake is a function of the blood solubility of a vapor, indicated by the blood/air partition coefficient. We hypothesized that blood lipid compositions are associated with the blood/air partition coefficients of lipophilic toxic vapors such as 1,3-butadiene. Our goal was to investigate cross-sectional and longitudinal relationships of blood triglycerides, total cholesterol, and albumin to the blood/air partition coefficient of butadiene. We collected blood samples from 24 subjects at three time points: a fasting baseline and 2 and 4 hr after drinking a standardized high-fat milk shake (107 g fat, 80 g sugar, and 27 g protein). The blood/air partition coefficient was determined using the closed vial-equilibrium technique. Triglycerides and total cholesterol were analyzed by an enzymatic method, and albumin was analyzed with an immunoassay technique. We used multiple linear regression and general linear models to examine the cross-sectional and longitudinal relationship, respectively. The results showed that the blood/air partition coefficient of butadiene was cross-sectionally associated only with triglycerides at baseline, and longitudinally related to baseline triglycerides, total cholesterol, and the change in triglycerides over time. The blood/air partition coefficient of butadiene increased, on average, by approximately 20% and up to 40% for subjects with borderline higher triglyceride levels after ingestion of a standardized milk shake. In addition, a time factor beyond lipids was also significant in predicting the blood/air partition coefficient of butadiene. This may represent the effects of other unmeasured parameters related to time or time of day on the blood/air partition coefficient of butadiene. Because the blood/air partition coefficient is a major determinant of gas uptake, ingestion of a high fat meal before this type of exposure may significantly increase an individual's absorbed dose, possibly increasing the risk of adverse effects.

    2016-08-10

    Lipid rafts are widely believed to be an essential organizational motif in cell membranes. However, direct evidence for interactions among lipid and/or protein components believed to be associated with rafts is quite limited owing, in part, to the small size and intrinsically dynamic interactions that lead to raft formation. Here, we exploit the single negative charge on the monosialoganglioside GM1, commonly associated with rafts, to create a gradient of GM1 in response to an electric field applied parallel to a patterned supported lipid bilayer. The composition of this gradient is visualized by imaging mass spectrometry using a NanoSIMS. Using this analytical method, added cholesterol and sphingomyelin, both neutral and not themselves displaced by the electric field, are observed to reorganize with GM1. This dynamic reorganization provides direct evidence for an attractive interaction among these raft components into some sort of cluster. At steady state we obtain an estimate for the composition of this cluster.

    Hyperhomocysteinemia and abnormal blood lipids are independent risk factors for stroke. However, whether both factors exert a synergistic effect in the onset of stroke remains unclear. The present study is a retrospective analysis of 2 089 cases of stroke and 2 089 control cases of simple inter-vertebral disk protrusion using a paired multivariate logistic regression method. Adjusting for known confounding variables including the patients’ age, gender, smoking status, alcohol consumption status, patient and family medical history, and clinical biochemical indices, elevated homocysteine level was related to the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids showed a 40.9%increase in the risk for stroke compared to patients with normal ho-mocysteine levels and blood lipids (odds ratio 1.409;95%confidence interval 1.127-1.761). These results indicate that elevated homocysteine and abnormal blood lipids exert synergistic effects in the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids are predis-posed to stroke.

    The determination of the permeability of drug candidates across the blood-brain barrier (BBB) is a fundamental step during drug discovery programs. The parallel artificial membrane permeability assay (PAMPA) is a high throughput screening tool applied to evaluate the passive permeability and adapted to predict BBB penetration. Herein, a new PAMPA model was developed using an in-house brain lipid extract capable of discriminating BBB permeable from non-permeable compounds. The apparent permeability (Papp) of 18 reference molecules and 10 test compounds was assessed and compared with phosphatidylcholine and commercial porcine polar brain lipid (PBL). The physicochemical selectivity of the in-house brain lipid extract was demonstrated by correlating Papp values with physicochemical properties and its predictive capacity estimated by establishing in vitro-in vivo correlations. The strong correlations achieved between 2% (w/v) in-house lipid extract and PBL for reference (r(2)=0.77) and test compounds (r(2)=0.94) support an equivalent discriminatory capacity and validate the presented model. Moreover, PAMPA studies performed with PBL and in-house lipid extract exhibited a higher correlation with the in vivo parameter logBB (r(2)=0.76 and r(2)=0.72, respectively) than phosphatidylcholine (r(2)=0.51). Overall, the applied lipid extraction process was reproducible, economical and provided lipid extracts that can be used to reliably assess BBB permeation.

    Full Text Available Lipid metabolism may be involved in the pathogenic mechanism of age-related macular degeneration (AMD. However, conflicting results have been reported in the associations of AMD with blood lipids. We performed a meta-analysis including a total of 19 studies to evaluate associations between blood lipids and this disease. The result reported that the high level of high-density lipoprotein cholesterol (HDL-C obtained with an increment of 1 mmol/L could result in a significantly increase in the AMD risk of approximately 18% (relative risk (RR, 1.18; 95% confidence interval (CI, 1.01 to 1.35; I2 = 53.8%; p = 0.007. High levels of total cholesterol (TC, low-density lipoprotein cholesterol (LDL-C, and triglycerides (TG were significantly associated with a decreased risk of AMD (RRs ranging from 0.92 to 0.95; all p < 0.05. The stratified analysis based on AMD subtypes showed that these blood lipids were only significantly associated with the risk of early AMD (all p < 0.05. The association between the blood lipids and AMD risk did not differ substantially based on the other characteristics of the participants. A high HDL-C level was associated with an increased AMD risk, whereas participants with high TC, LDL-C, and TG concentrations may show a decreased risk for this disease. Further well-designed large studies are warranted to confirm the conclusions.

    2007-01-01

    Objective To investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population. Methods Plasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey (CNHS) in 2002 which involved 14 252 participants at the age of 18 years or older. Results The mean levels of total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) in the participants were 3.81 mmol/L, 1.10 mmol/L, and 1.30 mmol/L, respectively. In the groups of participants at the age of 18-44 years, 45-59 years, and over 60 years the mean TC level was 3.70 mmol/L, 4.09 mmol/L and 4.21 mmol/L,respectively, and the mean TG level was 07 mmol/L, 1.21 mmol/L, 1.20 mmol/L, 1.29 mmol/L, 1.33 mmol/L, and 1.33 mmol/L,respectively. The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females.Dyslipidemia prevalence was higher in urban districts than in rural areas (21.0% vs. 17.7%). The prevalence of hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol was 2.9%, 11.9%, and 7.4% respectively among the participants. Conclusion Dyslipidemia has become one of the important health risk factors in the Chinese population. There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years. This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population.

    Numerous studies have examined relationships between disease biomarkers (such as blood lipids) and levels of circulating or cellular fatty acids. In such association studies, fatty acids have typically been expressed as the percentage of a particular fatty acid relative to the total fatty acids in a sample. Using two human cohorts, this study examined relationships between blood lipids (TAG, and LDL, HDL or total cholesterol) and circulating fatty acids expressed either as a percentage of total or as concentration in serum. The direction of the correlation between stearic acid, linoleic acid, dihomo-γ-linolenic acid, arachidonic acid and DHA and circulating TAG reversed when fatty acids were expressed as concentrations v. a percentage of total. Similar reversals were observed for these fatty acids when examining their associations with the ratio of total cholesterol:HDL-cholesterol. This reversal pattern was replicated in serum samples from both human cohorts. The correlations between blood lipids and fatty acids expressed as a percentage of total could be mathematically modelled from the concentration data. These data reveal that the different methods of expressing fatty acids lead to dissimilar correlations between blood lipids and certain fatty acids. This study raises important questions about how such reversals in association patterns impact the interpretation of numerous association studies evaluating fatty acids and their relationships with disease biomarkers or risk.

  11. EFFECTS OF EXERCISE TRAINING ON BLOOD LIPIDS AND LIPOPROTEINS IN CHILDREN AND ADOLESCENTS

    Kerstin Stoedefalke

    2007-09-01

    Full Text Available The following review aims to describe what is known about the effects of exercise training in children and adolescents on the following blood lipids and lipoproteins: total cholesterol (TC, high density lipoprotein cholesterol (HDL-C, low density lipoprotein cholesterol (LDL-C, and triglycerides (TG. Only studies that described mode, frequency, duration and intensity of the exercise were included in the review. The results of the studies reviewed were equivocal. Clearly the effects of exercise training on the blood lipid and lipoprotein levels of normolipidemic children and adolescents are equivocal. Of the 14 studies reviewed, six observed a positive alteration in the blood lipid and lipoprotein profile, four of the studies observed no alteration in the blood lipid and lipoprotein profile and one study observed a negative effect on HDL-C but an overall improvement in the lipid and lipoprotein profile due to the decrease in the TC/HDL ratio. It appears that methodological problems present in the majority of the exercise training studies limits the ability to make a conclusive, evidence based statement regarding the effect exercise training has on blood lipid levels in normolipidemic children. Most of the research design flaws can be linked to one or more of the following: small numbers of subjects in each study, low or no representation of girls, inclusion of both boys and girls in the subject pool, inclusion of boys and girls at different maturational stages in the subject pool, exercise training regimes that do not adequately control for exercise intensity, exercise training regimes that do not last longer than 8 weeks and exercise training studies that do not have an adequate exercise volume to elicit a change. Ideally, future research should focus on longitudinal studies which examine the effects of exercise training from the primary school years through adulthood

  12. Low levels of blood lipids are associated with etiology and lethal outcome in acute liver failure.

    Directory of Open Access Journals (Sweden)

    Paul Manka

    Full Text Available Emerging data links different aspects of lipid metabolism to liver regeneration. In patients with acute liver failure (ALF, low levels of lipids may correlate with disease severity. Thus, we determined whether there is an etiology-specific link between lipid levels in patients suffering from ALF and aimed to investigate an effect of lipid levels on the prognosis of ALF.In this retrospective single center study, we reviewed 89 consecutive ALF patients, who met the criteria of the "Acute Liver Failure Study Group". Patient characteristics, clinical data and laboratory parameters were individually analyzed at admission and correlated with the patients' outcome after a four week follow up. Possible endpoints were either discharge, or death or liver transplantation.High-density lipoprotein (HDL, cholesterol and triglyceride levels were significantly lower in patients who died or required a liver transplant. HDL levels were significantly higher in patients with ALF caused by acetaminophen intoxication, compared to fulminant HBV infection or drug induced liver injury. HDL levels correlated with hepatic injury by ALT levels, and Albumin, and inversely correlated with the MELD score, INR, and bilirubin.In our cohort of patients with ALF, we could show that HDL and cholesterol are suppressed. In addition novel etiology specific patterns between acteminophen and non-acteminophen induced liver failure were detected for serum lipid components. Further studies are needed to address the role of cholesterol and lipid metabolism and the according pathways in different etiologies of ALF.

    Diffuse correlation spectroscopy (DCS) measurements of blood flow rely on the sensitivity of the temporal autocorrelation function of diffusively scattered light to red blood cell (RBC) mean square displacement (MSD). For RBCs flowing with convective velocity [Formula: see text], the autocorrelation is expected to decay exponentially with [Formula: see text], where [Formula: see text] is the delay time. RBCs also experience shear-induced diffusion with a diffusion coefficient [Formula: see text] and an MSD of [Formula: see text]. Surprisingly, experimental data primarily reflect diffusive behavior. To provide quantitative estimates of the relative contributions of convective and diffusive movements, we performed Monte Carlo simulations of light scattering through tissue of varying vessel densities. We assumed laminar vessel flow profiles and accounted for shear-induced diffusion effects. In agreement with experimental data, we found that diffusive motion dominates the correlation decay for typical DCS measurement parameters. Furthermore, our model offers a quantitative relationship between the RBC diffusion coefficient and absolute tissue blood flow. We thus offer, for the first time, theoretical support for the empirically accepted ability of the DCS blood flow index ([Formula: see text]) to quantify tissue perfusion. We find [Formula: see text] to be linearly proportional to blood flow, but with a proportionality modulated by the hemoglobin concentration and the average blood vessel diameter.

  15. Top-down lipidomics reveals ether lipid deficiency in blood plasma of hypertensive patients.

    Directory of Open Access Journals (Sweden)

    Juergen Graessler

    Full Text Available BACKGROUND: Dyslipoproteinemia, obesity and insulin resistance are integrative constituents of the metabolic syndrome and are major risk factors for hypertension. The objective of this study was to determine whether hypertension specifically affects the plasma lipidome independently and differently from the effects induced by obesity and insulin resistance. METHODOLOGY/PRINCIPAL FINDINGS: We screened the plasma lipidome of 19 men with hypertension and 51 normotensive male controls by top-down shotgun profiling on a LTQ Orbitrap hybrid mass spectrometer. The analysis encompassed 95 lipid species of 10 major lipid classes. Obesity resulted in generally higher lipid load in blood plasma, while the content of tri- and diacylglycerols increased dramatically. Insulin resistance, defined by HOMA-IR >3.5 and controlled for BMI, had little effect on the plasma lipidome. Importantly, we observed that in blood plasma of hypertensive individuals the overall content of ether lipids decreased. Ether phosphatidylcholines and ether phosphatidylethanolamines, that comprise arachidonic (20:4 and docosapentaenoic (22:5 fatty acid moieties, were specifically diminished. The content of free cholesterol also decreased, although conventional clinical lipid homeostasis indices remained unaffected. CONCLUSIONS/SIGNIFICANCE: Top-down shotgun lipidomics demonstrated that hypertension is accompanied by specific reduction of the content of ether lipids and free cholesterol that occurred independently of lipidomic alterations induced by obesity and insulin resistance. These results may form the basis for novel preventive and dietary strategies alleviating the severity of hypertension.

    Maternal obesity during pregnancy may influence fetal development and possibly predispose offspring to cardiovascular disease. The aim of the present study was to evaluate the relationship between maternal pre-pregnancy body mass index (BMI) and weight gain during pregnancy, and newborn birth weight, with lipid profile, high-sensitivity C-reactive protein (hs-CRP) and leukocyte in newborns. We performed a cross-sectional study of 245 mothers and their children. Blood was collected from the umbilical vein and assayed for lipid profile, hs-CRP and leukocyte count. Newborns average weight was 3241 g, total cholesterol 53.9 mg/dl, high-density lipoprotein cholesterol (HDL-c) 21.9 mg/dl, low-density lipoprotein cholesterol (LDL-c) 26.2 mg/dl, triglyceride 29.5 mg/dl and leukocytes 13,777/mm3. There was a direct correlation of pre-pregnancy BMI of overweight mothers with total cholesterol (r=0.220, P=0.037) and LDL-c (r=0.268, P=0.011) of newborns. Total cholesterol, LDL-c and HDL-c were higher in pre-term newborns (66.3±19.7, 35.9±14.6 and 25.2±7.7 mg/dl, respectively) that in full-term (52.4±13.1, 25.0±8.7 and 21.5±6.0 mg/dl), with P=0.001, 0.001 and 0.003, respectively. Leukocyte counts were higher in full-term newborns (14,268±3982/mm3) compared with pre-term (9792±2836/mm3, Pprogramming of the immune system.

    High protein intake in early childhood is associated with obesity, suggesting possible adverse effects on other cardiometabolic outcomes. However, studies in adults have suggested beneficial effects of protein intake on blood pressure (BP) and lipid profile. Whether dietary protein intake is associated with cardiovascular and metabolic health in children is unclear. Therefore, we aimed to systematically review the evidence on the associations of protein intake with BP, insulin sensitivity and blood lipids in children. We searched the databases Medline, Embase, Cochrane Central and PubMed for interventional and observational studies in healthy children up to the age of 18 years, in which associations of total, animal and/or vegetable protein intake with one or more of the following outcomes were reported: BP; measures of insulin sensitivity; cholesterol levels; or TAG levels. In the search, we identified 6636 abstracts, of which fifty-six studies met all selection criteria. In general, the quality of the included studies was low. Most studies were cross-sectional, and many did not control for potential confounders. No overall associations were observed between protein intake and insulin sensitivity or blood lipids. A few studies suggested an inverse association between dietary protein intake and BP, but evidence was inconclusive. Only four studies examined the effects of vegetable or animal protein intake, but with inconsistent results. In conclusion, the literature, to date provides insufficient evidence for effects of protein intake on BP, insulin sensitivity or blood lipids in children. Future studies could be improved by adequately adjusting for key confounders such as energy intake and obesity.

  20. Saturated fat consumption may not be the main cause of increased blood lipid levels.

    2014-02-01

    Consumption of foods rich in saturated fatty acids (SFA) has often been associated with elevated blood lipid levels and consequently with risk for chronic diseases, including coronary heart disease. However, epidemiological and interventional studies on this topic are contradictory. While some studies have established a positive link, other studies have failed to show a significant association between saturated fat consumption and blood lipid levels, and others have even found an inverse association. Moreover, studies using animal models have demonstrated that dietary saturated fats raise blood lipid (cholesterol and triglycerides) levels only when the diet is deficient in omega-3 polyunsaturated fatty acids (n-3PUFA). The n-3PUFA are known for their potential in the management of hyperlipidaemia for the prevention of coronary heart disease, as well as for their anti-arrhythmic, anti-aggregatory and anti-inflammatory potential. We believe that with an adequate consumption of n-3PUFA dietary saturated fat may not result in elevated blood lipid levels. Therefore, we critically evaluated the literature regarding saturated fat and blood lipid level, with an emphasis on the role of n-3PUFA on this relationship. Evidence from animal studies and few clinical trials lead to the hypothesis that there are beneficial or neutral effects of saturated fatty acids when combined with recommended levels of n-3PUFA in the diet. However, an intervention focusing on the background fat when the volunteers' diet is supplemented with n-3PUFA is yet to be done. Proving the authenticity of this hypothesis would mean a substantial change in public health messages regarding saturated fats and their health effects; and also a change in the strategies related to prevention of chronic cardiac and artery diseases.

    Obesity is a risk factor for metabolic diseases. Intramuscular lipid accumulation of ceramides, diacylglycerols, and long chain acyl-CoA is responsible for the induction of insulin resistance. These lipids are probably implicated in obesity-associated insulin resistance not only in skeletal muscle but also in fat tissue. Only few data are available about ceramide content in human subcutaneous adipose tissue. However, there are no data on DAG and LCACoA content in adipose tissue. The aim of our study was to measure the lipids content in human SAT and epicardial adipose tissue we sought to determine the bioactive lipids content by LC/MS/MS in fat tissue from lean non-diabetic, obese non-diabetic, and obese diabetic subjects and test whether the lipids correlate with HOMA-IR. We found, that total content of measured lipids was markedly higher in OND and OD subjects in both types of fat tissue (for all p fat tissue and the particular lipids content positively correlates with HOMA-IR.

    We have studied specific features of lipid peroxidation in whole human blood under the action of aqueous solutions of xymedone (19.6 microM), phytic acid (117.9 microM) and its complex (237.6 microM) synthesized in distilled water and isotonic (0.9%) solution of sodium chloride. The estimated parameters included lipid peroxidation (LPO) rate, total antioxidant potential, superoxide dismutase (SOD) level, and malonic dialdehyde (MDA) level in blood plasma and erythrocytes. It was established that the effect of phytic acid on blood samples includes moderate stimulation of total antioxidant activity and SOD activity with predominant prooxidant effect. The phytic acid--xymedone complex synthesized in distilled water exhibits an antioxidant action, while its synthesis in saline solution yields a prooxidant.

    The total and positional fatty acid composition in camphor tree (Cinnamomum camphora) seed kernel oil (CKO) were analyzed, and for the first time, the effect of CKO on body fat deposition and blood lipids in rats was studied. The major fatty acids in CKO were determined to be decanoic acid (C10:0, 51.49%) and dodecanoic acid (C12:0, 40.08%), and uniformly distributed at Sn-1, 3, and Sn-2 positions in triglyceride (TG). Rats were randomly divided into control, CKO, lard, and soybean oil groups. At the end of the experiment, levels of blood lipids and the fats of abdomen in the rats were measured. The main organ were weighted and used for the histological examination. The results showed that body weight and fat deposition in CKO group were significantly lower than the lard and soybean groups. Moderate consumption of CKO was found to improve the levels of blood TG and low density lipoprotein cholesterol.

    Abnormal lipid levels are important etiological factors associated with the development of atherosclerosis and with increased cardiovascular morbidity and mortality. Lipid levels are also influenced by lifestyle and behavioral factors, which suggests that personality traits might be related to abnormal lipid profiles. Studies on personality traits and lipid levels are relatively scarce in Korea. Therefore, the objective of this study was to examine the association between lipid levels and personality traits in young Korean women. A total of 1,701 young Korean women [mean age  = 24.9±4.6 years (range 17-39)] who volunteered for personality trait evaluation were recruited for this study. Lipid levels, including total cholesterol, high density lipoprotein (HDL) cholesterol, and triglyceride, were measured in all subjects after an overnight fast, and a low density lipoprotein (LDL) cholesterol level was calculated. The study population was divided into abnormal and normal lipid level groups according to the clinical criteria. Personality traits were measured using the Revised NEO Personality Inventory for the Five-Factor Model of personality. High neuroticism was associated with low HDL cholesterol levels. Low extraversion and openness were associated with high levels of triglyceride. At the facet level, the association between personality and lipid levels were generally consistent. Angry hostility, self-consciousness, vulnerability to stress, activity, and straightforwardness were associated with HDL cholesterol levels. Activity, positive emotion, aesthetics, actions, and deliberation were associated with triglyceride. When applying clinical criteria, conscientiousness was less likely to have abnormal total cholesterol levels. Our results showed that the women with the low HDL cholesterol levels are like to be more neurotic and the hyperglycemic women are prone to lower extraversion and openness in Korea.

    Management of hyperlipidaemia remains a cornerstone therapy for the prevention of cardiovascular disease (CVD). Dietary supplementation with n-3 polyunsaturated fatty acid (PUFA) has been shown to modulate blood lipid profiles and reduce the risk of developing CVD. However, studies relating objective measures of long-term dietary n-3 PUFA intake and circulating lipid levels in older adults are limited. Thus, we aimed to determine whether there is an association between erythrocyte n-3 PUFA status (omega-3 index, O3I) and blood lipid profiles in older adults. A sample of adults aged 65-95 years who participated in the Retirement Health and Lifestyle Study was evaluated. Outcome measures included O3I (% eicosapentaenoic acid+% docosahexaenoic acid) and fasting blood lipid profiles [total cholesterol (TC), low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol and triglyceride (TG)]. Two hundred and seventy-six subjects were included in the analyses. The mean±SD age was 77.6±7.4 years, and 40.9% were males. O3I was significantly higher in females compared to males. O3I was inversely associated with plasma TG (Plipid profiles in older Australians. Our findings support the development and implementation of age-specific dietary strategies to reduce the risk of CVD via improving the O3I.

    Full Text Available Abstract Background The high blood lipid levels and obesity are one of the main risk factors for cardiovascular diseases, and the atherosclerotic process begins in childhood. Some environmental factors are supposed to be involved in this relationship, such as dietary factors. This study aimed to investigate the relationship between dietary intake and blood lipids levels in overweight and obese schoolchildren. Methods This is a cross-sectional study with 147 overweight and obese schoolchildren in Botucatu city, Brazil. The anthropometric measurements (body weight, height, body mass index, waist circumference and skinfolds, pubertal staging evaluation and biochemical tests were taken in all children. Three 24h-recall were applied in order to estimate the dietary intake and its relationship with blood lipid levels. The Student t test and multiple linear regression analysis were used for statistical analysis. Statistical significance was assessed at the level of 0.05. The data were processed in SAS software (version 9.1.3; SAS Institute. Results At this study, 63% of children were obese (body mass index higher than 95th percentile and 80% showed high body fat percentage. The percentage of children with abnormal total cholesterol and triglycerides was 12% and 10%, respectively, and 28% presented at least one abnormal lipid levels. The average values of anthropometric measurements were higher in children with elevated lipid levels. Total cholesterol levels were positively related to full-fat dairy products and triglycerides levels to saturated fat percentage. Conclusions Saturated fat was positively associated with elevated lipid levels in overweight and obese schoolchildren. These results reinforce the importance of healthy dietary habits since childhood in order to reduce the risks of cardiovascular diseases in adulthood.

    Organophosphorus (OP) pesticide self-poisoning is a major clinical problem in rural Asia and it results in the death of 200,000 people every year. At present, it is lack of effective methods to treat severe organophosphate poisoning. The high mortality rate lies on the amount of toxic absorption. Intravenous lipid emulsions can be used as an antidote in fat-soluble drug poisoning. The detoxification mechanism of intravenous lipid emulsions is "lipid sink", which lipid emulsions can dissolve the fat-soluble drugs and separate poison away from the sites of toxicity. Most of organophosphorus pesticides are highly fat-soluble. So, intravenous lipid emulsions have the potentially clinical applications in treatment of OP poisoning. Extracorporeal blood purification especially charcoal hemoperfusion is an efficient way to eliminate the poison contents from the blood. We hypothesize that the combination of intravenous lipid emulsions and charcoal hemoperfusion can be used to cure severe organophosphate poisoning. This novel protocol of therapy comprises two steps: one is obtained intravenous access to infuse lipid emulsions as soon as possible; another is that charcoal hemoperfusion will be used to clear the OP substances before the distribution of OP compounds in tissue is not complete. The advantages of this strategy lie in three points. Firstly, it will alleviate the toxic effect of OP pesticide in the patients by isolation and removal the toxic contents. Secondly, the dosage of antidotes can be reduced and its side-effects will be eased. Thirdly, a large bolus of fatty acids provide energy substrate for the patients who are nil by mouth. We consider that it would become a feasible, safe and efficient detoxification intervention in the alleviation of severe organophosphate poisoning, which would also improve the outcome of the patients.

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

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

    Growing evidence suggests that decreased functional connectivity in cortical networks precedes clinical stages of Alzheimer's disease (AD), although our knowledge about cerebral and biological correlates of this phenomenon is limited. To shed light on this issue, we have investigated whether resting-state oscillatory connectivity patterns in healthy older (HO) and amnestic mild cognitive impairment (aMCI) subjects are related to anatomical grey matter (GM) and functional (2-[18F]fluoro-2-deoxy-D-glucose (FDG)-PET) changes of neuroelectric sources of alpha rhythms, and/or to changes in plasma amyloid-beta (Aβ) and serum lipid levels, blood markers tied to AD pathogenesis and aging-related cognitive decline. We found that aMCI subjects showed decreased levels of cortical connectivity, reduced FDG-PET intake of the precuneus, and GM atrophy of the thalamus, together with higher levels of Aβ and apolipoprotein B (ApoB) compared to HO. Interestingly, levels of high-density lipoprotein (HDL) cholesterol were positively correlated with the strength of neural-phase coupling in aMCI subjects, and increased triglycerides accompanied bilateral GM loss in the precuneus of aMCI subjects. Together, these findings provide peripheral blood correlates of reduced resting-state cortical connectivity in aMCI, supported by anatomo-functional changes in cerebral sources of alpha rhythms. This framework constitutes an integrated approach to assess functional changes in cortical networks through neuroimaging and peripheral blood markers during early stages of neurodegeneration.

    Blood adenosine metabolism, including metabolites and metabolizing enzymes, was studied during the sleep period in human volunteers. Searching for significant correlations among biochemical parameters found: adenosine with state 1 of slow-wave sleep (SWS); activity of 5'-nucleotidase with state 2 of SWS; inosine and AMP with state 3-4 of SWS; and activity of 5'-nucleotidase and lactate with REM sleep. The correlations were detected in all of the subjects that presented normal hypnograms, but not in those who had fragmented sleep the night of the experiment. The data demonstrate that it is possible to obtain information of complex brain operations such as sleep by measuring biochemical parameters in blood. The results strengthen the notion of a role played by adenosine, its metabolites and metabolizing enzymes, during each of the stages that constitute the sleep process in humans.

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

    The present study aimed to systematically review the literature about intima-media thickness (IMT), blood pressure (BP), and lipid profile (LP) in obese and non-obese children and adolescents. The search was carried out in electronic databases (PubMed, Bireme, and Elsevier ScienceDirect) between 2000-2010. The following keywords, in English, were used: "obesity", "adolescents", "atherosclerosis" and "child", using two combinations: obesity+child+atherosclerosis and obesity+adolescents+atherosclerosis. The electronic search resulted in 3,211 manuscripts. After analysis of the inclusion criteria, 13 papers were selected. Of these, two studies showed significant correlation between IMT and the variables BP, LDL, and triglycerides. In other studies, no significant correlations were found. There is a wide methodological variability across the studies. However, obese children and adolescents had higher values of IMT, BP, and LP.

    Full Text Available Metabolic diseases in China have been on the rise in recent decades, partially due to reduced cereal consumption and excessive intake of low glycemic index (GI foods such as meat and oil. Although the relationship between dietary glycemic load (GL and various metabolic diseases has been extensively studied worldwide, it is unclear whether dietary GL is related to blood lipid levels and dyslipidemia risk in Chinese. The aim of the present study was to investigate the relationship between dietary GL and blood lipid levels and dyslipidemia risk in hospitalized Chinese adults.Dietary GL in 2258 hospitalized Chinese adults was calculated based upon GI, carbohydrate content and daily intake of individual foods. In addition, fasting total cholesterol (TC, triglycerides (TG, HDL cholesterol (HDL-C and LDL cholesterol (LDL-C data were collected. Multiple regression and logistic regression analysis were used to determine the relationship between dietary GL and plasma lipid levels or dyslipidemia risk.Dietary GL remained inversely associated with blood total cholesterol (TC and low-density lipoprotein cholesterol (LDL-C (P0.05.High GL diet, as represented by traditional Chinese dietary pattern, may contribute to reduced risk of dyslipidemia in Chinese adults.

  2. Theoretical model of blood flow measurement by diffuse correlation spectroscopy

    2017-02-01

    Diffuse correlation spectroscopy (DCS) is a noninvasive method to quantify tissue perfusion from measurements of the intensity temporal autocorrelation function of diffusely scattered light. However, DCS autocorrelation function measurements in tissue better match theoretical predictions based on the diffusive motion of the scatterers than those based on a model where the advective nature of blood flow dominates the stochastic properties of the scattered light. We have recently shown using Monte Carlo (MC) simulations and assuming a simplistic vascular geometry and laminar flow profile that the diffusive nature of the DCS autocorrelation function decay is likely a result of the shear-induced diffusion of the red blood cells. Here, we provide theoretical derivations supporting and generalizing the previous MC results. Based on the theory of diffusing-wave spectroscopy, we derive an expression for the autocorrelation function along the photon path through a vessel that takes into account both diffusive and advective scatterer motion, and we provide the solution for the DCS autocorrelation function in a semi-infinite geometry. We also derive the correlation diffusion and correlation transfer equation, which can be applied for an arbitrary sample geometry. Further, we propose a method to take into account realistic vascular morphology and flow profile.

    The purpose of this study is to investigate the effect of resistance exercise on fitness, blood pressure, and blood lipid of hypertensive middle-aged men. To achieve the goal of the study, a total of 23 subjects were selected. Among them, 14 subjects who exercised regularly were selected as the exercise group, while the remaining 9 subjects were selected as the control group. In terms of data processing, the IBM SPSS Statistics ver. 21.0 software was used to calculate the mean and standard deviation. Regarding the verification of difference on the change of means between the groups, analysis of covariance was used for statistical process. As a result, significant differences were found in cardiovascular endurance, muscle endurance, flexibility, and triglyceride. These results indicate that the resistance exercise only had slight effect on hypertensive middle-aged men.

    1997-05-01

    In a placebo-controlled study the effect of ginger and fenugreek was examined on blood lipids, blood sugar, platelet aggregation, fibrinogen and fibrinolytic activity. The subjects included in this study were healthy individuals, patients with coronary artery disease (CAD), and patients with non-insulin-dependent diabetes mellitus (NIDDM) who either had CAD or were without CAD. In patients with CAD powdered ginger administered in a dose of 4 g daily for 3 months did not affect ADP- and epinephrine-induced platelet aggregation. Also, no change in the fibrinolytic activity and fibrinogen level was observed. However, a single dose of 10 g powdered ginger administered to CAD patients produced a significant reduction in platelet aggregation induced by the two agonists. Ginger did not affect the blood lipids and blood sugar. Fenugreek given in a dose of 2.5 g twice daily for 3 months to healthy individuals did not affect the blood lipids and blood sugar (fasting and post prandial). However, administered in the same daily dose for the same duration to CAD patients also with NIDDM, fenugreek decreased significantly the blood lipids (total cholesterol and triglycerides) without affecting the HDL-c. When administered in the same daily dose to NIDDM (non-CAD) patients (mild cases), fenugreek reduced significantly the blood sugar (fasting and post prandial). In severe NIDDM cases, blood sugar (both fasting and post prandial) was only slightly reduced. The changes were not significant. Fenugreek administration did not affect platelet aggregation, fibrinolytic activity and fibrinogen.

    Full Text Available Fluorescence correlation spectroscopy (FCS is a single molecule technique used mainly for determination of mobility and local concentration of molecules. This review describes the specific problems of FCS in planar systems and reviews the state of the art experimental approaches such as 2-focus, Z-scan or scanning FCS, which overcome most of the artefacts and limitations of standard FCS. We focus on diffusion measurements of lipids and proteins in planar lipid membranes and review the contributions of FCS to elucidating membrane dynamics and the factors influencing it, such as membrane composition, ionic strength, presence of membrane proteins or frictional coupling with solid support.

    Nine multiparous Holstein cows (average 5.8 yr, 63 to 132 days postpartum) were in a 28-day single reversal experiment in the Beltsville open circuit respiration chambers with two 14-day injection periods (placebo versus bovine growth hormone, 51.5 IU/day). With growth hormone treatment, milk fat percentage increased 25 to 29%, milk fat yield increased 41%, and cows averaged -13.7 Mcal/day energy balance. There were small increases of triglycerides and 1,2-diglycerides, core lipids, and small decreases of cholesterol and phospholipids, the membrane lipids. Fat from growth hormone treatment had 6% less short (6:0, 8:0, 10:0) and medium (12:0, 14:0, 14:1, 15:0, 16:0) chain fatty acids and 6% more long chain 18:1 fatty acids. Plasma of cows treated with growth hormone had an increase of concentrations of free fatty acids, but no shifts were apparent among other lipid classes. Analysis of total plasma fatty acids did not show any net changes, but within individual plasma lipid classes, 18:1 increased and 18:2 decreased. Overall changes of blood and milk lipids are consistent with the concept that adipose tissue reserves were mobilized in response to hormone treatment and that these mobilized lipids were the major carbon source for the 41% increase of milk fat secretion. Increases of de novo synthesis of short and medium chain fatty acids also occurred but much less. Cows treated with growth hormone were in negative energy balance, and the mechanism may differ when cows are in positive energy balance.

    Full Text Available Dyslipidemia is a risk factor causing cardiovascular disease and compliance to dietary counselling results in an improved lipid profile. The present study aimed to assess the compliance to dietary counselling and its barriers among dyslipidemic individuals attending dietary follow-ups counselling in Diet Clinic of Universiti Kebangsaan Malaysia Medical Centre (UKMMC. A cross sectional study using the convenience sampling technique was conducted from May to June 2012. Data on food intake, lifestyle habits, physical activity level and barriers in adhering to dietary counselling were collected using interview-based questionnaires. Anthropometric measurements were conducted, while blood lipid profile and medical information were obtained from medical records. The results showed that non-compliance is prevalent among dyslipidemic patients who received dietary counselling. Most subjects (81% were unable to achieve at least four of the therapeutic lifestyle change dietary recommendations as outlined by National Cholesterol Education Program Adult Treatment Panel III. Factors such as time, food taste and price have been reported as the main barriers to comply towards dietary counselling. A significantly higher proportion of those in non-compliance group did not meet total fat (p < 0.001 and saturated fat (p < 0.001 recommendations as compared to the compliance group. In conclusion, acknowledgements of barriers while providing dietary education are necessary to improve dyslipidemic patients’ compliance with controlling blood lipid.

    Full Text Available Bisphosphonates are currently the most preferred class of drugs used for the treatment of metabolic bone disease such as osteoporosis and Paget’s disease. Although their exact mechanism has not been identified, the compounds containing amino group (amino bisphosphonates were shown to decrease osteoclast activation by inhibiting mevalonate pathway. Because mevalonate pathway is essential in production of cholesterol, these compounds could also interfere with cholesterol synthesis. In the present study, the effects of aminobisphosphonates on lipid parameters in subjects who were diagnosed as osteoporosis were investigated. For this reason, 50 postmenopausal osteoporotic subjects were included in the study and 25 of them (mean age:54±9 years received alendronate sodium (70mg/week and the remaining 25 subjects (mean age:55±8 years were given risedronate sodium (35mg/week. Blood samples were analyzed at baseline and at the end of sixth months. Total cholesterol, high density cholesterol (HDL-chol, low density cholesterol (LDL-chol, triglyceride, apolipoprotein A (Apo-A, apolipoprotein B (Apo-B and lipoprotein (a (Lip a were investigated as lipid parameters. Total alkaline phophatase (TAP, bone-specific alkaline phophatase (BAP, osteocalcine (OCL and urine deoxyprydolin (DPD levels were assessed as bone remodeling markers. After six month treatment period, while significant changes were observed in bone remodeling parameters (p0.05. Our results suggest that moderate-term oral aminobisfosphonate treatment has no significant effect on blood lipid parameters.

    Organochlorine pesticides, due to their hydrophobic nature and persistence, accumulate in tissues rich in lipids, which had been used as a biomarker for environmental pollution. In humans, organochlorine pesticides are continuously circulating and equilibrating among body compartments. The objective of the study was to evaluate the concentrations of organochlorine pesticides in blood serum and compare their levels to the total lipid contents in Veracruz, México inhabitants. Our hypothesis is that concentrations of organochlorine pesticides will increase just as lipid concentrations. Levels of organochlorine pesticides were divided in ascending tertils according to their total lipid content. The linear trend model applied surprisingly reveals that the average level of all organochlorine pesticides decreases as the lipid concentration increases. From one tertil to the next β-HCH, it shows a decrease of -3.19 mg kg(-1) on lipid basis, pp.'DDE levels decrease by -3.70 mg kg(-1) on lipid basis and pp.'DDT levels decrease -1.13 mg kg(-1) on lipid basis. We conclude that the levels and the orderly sequence of organochlorine pesticide distributions in the blood serum maintain an inverse relationship to total lipid blood serum concentrations.

    Full Text Available The present study aims at evaluation mechanisms of natural plant eleutheroside extracts for ameliorating the blood lipid and blood glucose. The eleutherosides derived from the roots of eleutheroccus senticosus and is purported to behave as an “adaptogen”, we assessed effects of eleutheroside at doses of 3.6, 7.2 and 14.4 g/(kg day on SD rats injected daily with D-gal (50 mg/(kg day. Eleutheroside-fed rats showed higher the level HDL-C, decrease the level of HCT, TG, TC, LDL-C compared with D-gal-treated rats. We further examined the mechanisms involved in effects of 3.63.6, 7.2 and 14.4 g/(kg day on rat blood. In summary, eleutheroside significantly increased Superoxide Dismutase (SOD activity and decreased the Malondialdehyde (MDA level.

    Various models have been proposed for the sequence of events occurring after binding of specific antimicrobial peptides to lipid membranes. The lipid clustering model arose by the finding that antimicrobial peptides can induce a segregation of certain negatively charged lipids in lipid model membranes. Anionic lipid segregation by cationic peptides is initially an effect of charge interaction where the ratio of peptide and lipid charges is thought to be the decisive parameter in the peptide induced lipid demixing. However, the sequence of events following this initial lipid clustering is more complex and can lead to deactivation of membrane proteins involved in cell division or perturbation of lipid reorganization essential for cell division. In this study we used DSC and ITC techniques to investigate the effect of binding different cyclic hexapeptides with varying antimicrobial efficacy, to phosphatidylglycerol (PG)/phosphatidylethanolamine (PE) lipid membranes and their ability to induce lipid segregation in these mixtures. We found that these cyclic hexapeptides consisting of three charged and three aromatic amino acids showed indeed different abilities to induce lipid demixing depending on their amino acid composition and their sequence. The results clearly showed that the cationic amino acids are essential for electrostatic binding but that the three hydrophobic amino acids in the peptides and their position in the sequence also contribute to binding affinity and to the extent of induction of lipid clustering. The efficacy of these different hexapeptides to induce PG clusters in PG/PE membranes was found to be correlated with their antimicrobial activity.

    Full Text Available BACKGROUND: Betaine (trimethylglycine lowers plasma homocysteine, a possible risk factor for cardiovascular disease. However, studies in renal patients and in obese individuals who are on a weight-loss diet suggest that betaine supplementation raises blood cholesterol; data in healthy individuals are lacking. Such an effect on cholesterol would counteract any favourable effect on homocysteine. We therefore investigated the effect of betaine, of its precursor choline in the form of phosphatidylcholine, and of the classical homocysteine-lowering vitamin folic acid on blood lipid concentrations in healthy humans. METHODS AND FINDINGS: We measured blood lipids in four placebo-controlled, randomised intervention studies that examined the effect of betaine (three studies, n = 151, folic acid (two studies, n = 75, and phosphatidylcholine (one study, n = 26 on plasma homocysteine concentrations. We combined blood lipid data from the individual studies and calculated a weighted mean change in blood lipid concentrations relative to placebo. Betaine supplementation (6 g/d for 6 wk increased blood LDL cholesterol concentrations by 0.36 mmol/l (95% confidence interval: 0.25-0.46, and triacylglycerol concentrations by 0.14 mmol/l (0.04-0.23 relative to placebo. The ratio of total to HDL cholesterol increased by 0.23 (0.14-0.32. Concentrations of HDL cholesterol were not affected. Doses of betaine lower than 6 g/d also raised LDL cholesterol, but these changes were not statistically significant. Further, the effect of betaine on LDL cholesterol was already evident after 2 wk of intervention. Phosphatidylcholine supplementation (providing approximately 2.6 g/d of choline for 2 wk increased triacylglycerol concentrations by 0.14 mmol/l (0.06-0.21, but did not affect cholesterol concentrations. Folic acid supplementation (0.8 mg/d had no effect on lipid concentrations. CONCLUSIONS: Betaine supplementation increased blood LDL cholesterol and triacylglycerol

    AIM: To assess the effects of soy protein, isoflavone, and saponin on liver and blood lipid in rats that consumed high-cholesterol diets.METHODS: High-cholesterol diets (1%) with or without soy material were fed to 6-wk-old male Sprague-Dawley rats for 8 wk. Blood lipids, liver lipids, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) levels were measured. The in vitro bile acid-binding ability of soy materials was analyzed.RESULTS: The results of in vitro studies showed that soy protein isolate had a significantly higher bile acid-binding ability (8.4±0.8%) than soy saponin (3.1±0.7%) and isoflavone (1.3±0.4%, P<0.05). On the other hand, at the end of the experimental period, rats that consumed soy protein diets had lower GOT and GPT levels than rats that consumed casein under high-cholesterol diets.Rats that consumed soy protein also had lower total cholesterol (TC) levels in the liver than those that consumed casein under high-cholesterol diets. Rats that consumed the soy protein diet containing both saponin and isoflavone had lower hepatic TC level than those that consumed the soy protein diet without isoflavone alone.The effect of different types of proteins on triglyceride was not significant.CONCLUSION: Consumption of soy provided benefits to control lipid levels under high-cholesterol dieting conditions in this rat model of hypercholesterolemia. The major component that reduced hepatic TC was not saponin, but possibly isoflavone.

    Cheese and butter have been shown to affect blood lipids differently. This parallel-arm, randomised, controlled study in 36 crossbred growing sows compared the effect of diets with either regular-fat cheese (REG), reduced-fat cheese + butter (RED) or butter (BUT) on blood lipids, faecal fat...... higher faecal fat excretion. Faecal energy excretion was only higher in REG, and this correlated with a lower microbiome Firmicutes-to-Bacteroidetes ratio. In conclusion, dairy fat consumed as cheese or butter caused different metabolic effects. Differences between reduced-fat cheese+butter and butter...... were less pronounced than differences between regular-fat cheese and butter, suggesting an impact of the dairy matrix....

    Full Text Available Introduction. Folk dance is a form of physical activity which helps develop the ability to use the whole body in a coordinated way with music, and folk dancers’ characteristics vary according to the particular type of dance practised in a given geographic region. The aims of the study were to evaluate the effects of 12-week folk dance training on blood oxidative stress level, lipids, lipoproteins, as well as muscle damage markers and to define some physical and physiological properties of folk dancers. Material and methods. Thirty-eight healthy male folk dancers aged 21-28 years having an average of 11 years of dance training experience voluntarily participated in the study. All of the physical and physiological measurements and the blood analysis were performed twice, before and after the training period which focused on different regional dances (Caucasus, Bar, Zeybek, Spoon Dance, Thracian dances, and Horon. The training was done 2 hours per day (a total of 10 hours a week, during a 12-week-long period. Results. All the blood parameters were found to be within the specified reference ranges. The training programme had no significant effect on the blood lipid profile, whereas it was found to have positive effects on body fat (p ≤ 0.012, peak oxygen consumption (VO2peak; p = 0.000, muscle damage markers (creatine kinase, Δ% = −19.6, and total antioxidant capacity (p ≤ 0.002. Conclusions. Regular folk dance training was found to have positive effects on body fat, VO2peak, blood total antioxidant capacity, and muscle damage markers. Based on these results, the community should be encouraged to perform folk dance as a recreational physical activity, and public awareness should be raised about the health benefits of practising folk dances.

    We aimed to assess the effects of childhood obesity prevention programmes on blood lipids in high-income countries. We searched MEDLINE®, Embase, PsychInfo, CINAHL®, clinicaltrials.gov, and the Cochrane Library up to 22 April 2013 for relevant randomized controlled trials, quasi-experimental studies and natural experiments published in English. Studies were included if they implemented diet and/or physical activity intervention(s) with ≥1 year follow-up (or ≥6 months for school-based intervention studies) in 2-18-year-olds, and were excluded if they targeted only overweight/obese children, or those with a pre-existing medical condition. Seventeen studies were finally included. For total cholesterol, the pooled intervention effect was -0.97 mg dL(-1) [95% confidence interval (CI): -3.26, 1.32; P = 0.408]; for low-density lipoprotein cholesterol (LDL-C), -6.06 mg dL(-1) (95% CI: -11.09, -1.02; P = 0.018); for high-density lipoprotein cholesterol (HDL-C), 1.87 mg dL(-1) (95% CI: 0.39, 3.34; P = 0.013); and for triglycerides, -1.95 mg dL(-1) (95% CI: -4.94, 1.04; P = 0.202). Most interventions (70%) showed similar significant or no effects on adiposity- and lipids outcomes: 15% interventions improved both adiposity- and lipids outcomes; 55% had no significant effects on either. Childhood obesity prevention programmes had a significant desirable effect on LDL-C and HDL-C. Two-thirds of interventions showed similar significant or no effects in adiposity- and lipids outcomes. Assessing lipids outcomes provide additional useful information on obesity prevention programme benefits.

    Abnormal lipid profile is often found in women with Polycystic Ovary Syndrome. To assess the impact of abnormal lipid profile on atherosclerosis in young Polycystic Ovary Syndrome women, carotid intima-media thickness as judged by B-mode ultrasonography were done in 30 young (18-35 yrs) Polycystic Ovary Syndrome women and in similarly age-matched 30 apparently healthy controls. Compared to controls, young Polycystic Ovary Syndrome women had significantly elevated serum total cholesterol, triglyceride and LDL-C levels and carotid intima-media thickness. HDL-C level did not differ significantly between two groups of women. In Polycystic Ovary Syndrome women carotid intima-media thickness was positively correlated with serum total cholesterol, triglyceride and LDL-C and negatively correlated with serum HDL-C. Our study suggests that even young Polycystic Ovary Syndrome women are prone to atherosclerosis from early age.

    Full Text Available Lipid-based formulations have been an attractive choice among novel drug delivery systems for enhancing the solubility and bioavailability of poorly soluble drugs due to their ability to keep the drug in solubilized state in the gastrointestinal tract. These formulations offer multiple advantages such as reduction in food effect and inter-individual variability, ease of preparation, and the possibility of manufacturing using common excipients available in the market. Despite these advantages, very few products are available in the present market, perhaps due to limited knowledge in the in vitro tests (for prediction of in vivo fate and lack of understanding of the mechanisms behind pharmacokinetic and biopharmaceutical aspects of lipid formulations after oral administration. The current review aims to provide a detailed understanding of the in vivo processing steps involved after oral administration of lipid formulations, their pharmacokinetic aspects and in vitro in vivo correlation (IVIVC perspectives.

    2011-06-01

    Anomalous diffusion has been observed abundantly in the plasma membrane of biological cells, but the underlying mechanisms are still unclear. In general, it has not been possible to directly image the obstacles to diffusion in membranes, which are thought to be skeleton bound proteins, protein aggregates, and lipid domains, so the dynamics of diffusing particles is used to deduce the obstacle characteristics. We present a supported lipid bilayer system in which we characterized the anomalous diffusion of lipid molecules using single molecule tracking, while at the same time imaging the obstacles to diffusion with atomic force microscopy. To explain our experimental results, we performed lattice Monte Carlo simulations of tracer diffusion in the presence of the experimentally determined obstacle configurations. We correlate the observed anomalous diffusion with obstacle area fraction, fractal dimension, and correlation length. To accurately measure an anomalous diffusion exponent, we derived an expression to account for the time-averaging inherent to all single molecule tracking experiments. We show that the length of the single molecule trajectories is critical to the determination of the anomalous diffusion exponent. We further discuss our results in the context of confinement models and the generating stochastic process.

    Periodontitis is characterized by systemic inflammatory host responses that may contribute to a higher risk for cardiovascular disease. We hypothesized that periodontitis may be associated with altered C-reactive protein levels, serum levels of lipids and peripheral blood counts, and that these characteristics may serve as markers for a link between periodontitis and cardiovascular disease. Sixty subjects, 25-60 years old, were divided into three groups of 20 subjects each. Group 1, age and sex matched healthy controls; group 2, patients diagnosed with chronic periodontitis; group 3, patients diagnosed with acute periodontal lesions including periodontal abscess and pericoronal abscesses. Serum C-reactive protein levels, lipid levels and peripheral blood counts were obtained for all three groups. Significant increases in C-reactive protein and serum lipid levels, and altered peripheral blood counts were observed between the experimental groups; these factors were correlated with chronic periodontitis and cardiovascular disease. These simple, economical clinical measurements can be used to assess periodontal tissue damage and may be useful for predicting risk of cardiovascular disease in these subjects.

    The study demonstrates the production of lipase (LIP) from Pseudomonas gessardii using blood tissue lipid as the substrate for the hydrolysis of blood cholesterol and triglycerides. The lipase was purified with the specific activity of 828 U/mg protein and the molecular weight of 56 kDa. The maximum lipase activity was observed at the pH 7.0 and the temperature 37 °C. The amino acid composition of purified lipase was determined by HPLC. The mesoporous activated carbon (MAC) was used for the immobilization of lipase for the repeated use of the enzyme catalyst. The K (m) value of immobilized lipase (MAC-LIP) and the free lipase (LIP) was 0.182 and 1.96 mM, respectively. The V (max) value of MAC-LIP and LIP was 1.33 and 1.26 mM/min, respectively. The MAC and MAC-LIP were characterized by scanning electron microscopy (SEM). The hydrolysis study showed 78 and 100% hydrolysis of triglycerides and cholesterol, respectively, for LIP and 84 and 100% hydrolysis of triglycerides and cholesterol, respectively, for MAC-LIP at the reaction time of 1 h. The effect of lipase on cell wall lysis was carried out on the RBCs of blood plasma. Interestingly, 99.9% lysis of RBCs was observed within 2 h. SEM images and phase contrast microscopy confirmed the lysis of RBCs. This work provides a potential biocatalyst for the hydrolysis of blood cholesterol and triglycerides.

    To see the possible relationship between COMT Val158Met polymorphism and blood pressure (BP) and serum lipid levels and its putative role in human longevity, we genotyped COMT Val158Met (rs4680) by PCR-RFLP for members from Bama long-lived families (BLF, n = 1538), Bama non-long-lived families (BNLF, n = 600), Pingguo (a county outside Bama region) long-lived families (PLF, n = 538) and Pingguo non-long-lived families (PNLF, n = 403) after anthropometric measures were collected and serum lipid levels were detected. The distribution of genotypes and alleles among four family groups was significantly different (all P 0.05). Correlation analyses revealed that COMT Val158Met was mainly correlated negatively with SBP, diastolic blood pressure (DBP) and LDL-C in BNLF and negatively with TC level in BLF, BNLF and PLF. These data suggest that COMT Val158Met polymorphism may have more impact on the modulation of BP and lipid profiles in the average families than in the long-lived families in Bama region. The association between this SNP and other phenotypes (e.g. cognition) and its roles in the longevity in Bama area thus warrant further investigation.

    Full Text Available Introduction: Hypercholesterolemia is a metabolic disorder that ultimately results in arterial sclerosis and complications like hypertension and coronary arterial diseases. Various drugs have been used for the treatment of this condition and many studies are underway for introducing new drugs. Chitosan and Salvadora Persica are two such drugs. Chitosan is produced by deacetylation of chitin which is present mainly in the exoskeleton of crustaceans. The aim of this invitro study was to study the effects of these two drugs on blood lipid levels. Methods: In this Interventional Laboratory Trial, 30 mature vistar rats weighing 200-250 grams were selected and after a period of two weeks in order to allow them to adapt to their surroundings, they were allotted randomly to 6 groups. The rats were then fed for a period of 15 days with normal or fatty diet, with or without the drugs. Chitosan in pure powder form and persica in the form of hydro alcoholic salvadora persica stem extract were added to the diet of the respective study groups. At the end of this period, blood samples were taken in order to measure cholesterol, triglyceride, HDL and LDL levels. Data was analyzed statistically using SPSS software program and Scheffe, ANOVA and Descriptive statistical tests. Results: Both chitosan and persica decreased cholesterol and LDL levels in the groups ingesting fatty diet (P 0.05. The two drugs had no effect on triglyceride and HDL levels. (P > 0.05 Both chitosan and persica had no effect on blood lipid levels of subjects on normal diet whose cholesterol levels were normal (P > 0.05. Conclusion: Persica and chitosan have similar effects on reduction of cholesterol and LDL levels in cases of hypercholesterolemia, but have no effect on triglyceride and HDL levels.

    Studies in animals and a short-term human study have suggested that curcumin, a polyphenolic compound concentrated in the curry spice turmeric, decreases serum cholesterol concentration. However, no controlled human trials have examined the effect of curcumin on cholesterol. This study investigated the effects of consuming curcumin on the serum lipid profile in men and women. Elderly subjects (n=36) consumed 4 g/d curcumin, 1g/d curcumin, or placebo in a 6-month, randomized, double-blind trial. Plasma curcumin and its metabolites were measured at 1 month, and the serum lipid profile was measured at baseline, 1 month, and 6 months. The plasma curcumin concentration reached a mean of 490 nmol/L. The curcumin concentration was greater after capsule than powder administration. Consumption of either dose of curcumin did not significantly affect triacylglycerols, or total, LDL, and HDL cholesterol over 1 month or 6 months. However, the concentrations of plasma curcumin and serum cholesterol were positively and significantly correlated. Curcumin consumption does not appear to have a significant effect on the serum lipid profile, unless the absorbed concentration of curcumin is considered, in which case curcumin may modestly increase cholesterol.

    With the development of society and the economy, many Chinese cities are shrouded in pollution haze for much of the year. Scientific studies have identified various adverse effects of air pollutants on human beings. However, the relationships between air pollution and blood lipid levels are still unclear. The objective of this study is to explore the short and long-term effects of air pollution on eight blood lipid markers among elderly hypertension inpatients complicated with or without type 2 diabetes (T2D). Blood lipid markers which met the pre-established inclusion criteria were exported from the medical record system. Air pollution data were acquired from the official environmental protection website. Associations between the air quality index and the blood lipid indexes were analyzed by one-way ANOVA and further Bonferroni correction. In an exposure time of 7 days or longer, blood lipid markers were somewhat affected by poor air quality. However, the results could not predict whether atherosclerosis would be promoted or inhibited by poorer air condition. Changes of blood lipid markers of hypertension inpatients with or without T2D were not completely the same, but no blood lipid markers had an opposite trend between the two populations. The air quality index was associated with changes to blood lipid markers to some extent in a population of hypertension inpatients with or without T2D. Further studies are needed to investigate the potential mechanism by which air pollutants induce blood lipids changes.

    Full Text Available Flavio Danni Fuchs, Sandra Costa Fuchs, Leila Beltrami Moreira, Miguel GusDivision of Cardiology and Postgraduate Studies Program in Cardiology, Hospital de Clinicas de Porto Alegre, Universidade Federal do Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, BrazilAbstract: High blood pressure and lipoprotein abnormalities were identified by many cohort studies as the major risk factors for cardiovascular disease. Laboratory experiments apparently confirmed their role in the causation of atherosclerosis, but a proof of concept requires the corroboration by clinical trials in human beings. The size of benefit in clinical trials regarding the control of high blood pressure was within the estimations of risk provided by cohort studies. For a reduction of 10 mmHg in systolic blood pressure or 5 mmHg in diastolic blood pressure, the relative risk reduction of coronary heart disease was 22% (95% confidence interval 27%–17% in a meta-analysis of clinical trials, close to the estimation of reduction of 25% (95% confidence interval 23%–27% provided by a meta-analysis of cohort studies. The corresponding values for stroke were 41% (95% confidence interval 33%–48% in clinical trials compared to a cohort risk prediction of 36% (95% confidence interval 34%–38%. This efficacy was shared by all blood pressure-lowering drugs. The same figure has not paradoxically happened with drugs that act over abnormalities of cholesterol and lipoproteins. Only statins, which have other beneficial actions as well, have consistently lowered the incidence of cardiovascular diseases, an efficacy that was not reproduced by older and newer quite potent lipid drugs. The adverse effects of these drugs may nullify their beneficial effects over lipoproteins and abnormalities of lipoproteins may only be surrogate markers of the underlying real risks.Keywords: proof of concept, hypertension, lipoproteins, clinical trials

    Previous clinical studies have reported mixed results regarding the effect of probiotics on lipid metabolism. Therefore, we conducted a meta-analysis of randomized controlled trials to quantify the direction and magnitude of the potential effect of probiotics on blood lipid concentrations.Eligible studies were randomized, placebo-controlled trials whose interventions were probiotic products containing live bacteria. The studies reported net changes in lipid profiles (total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides) and their associated standard deviations (or the data to calculate them). The probiotic products did not contain prebiotics or other active ingredients, and the full article was accessible in English.The pooled mean net change in lipid profiles and 95% confidence intervals (95% CIs) were calculated. Q statistics and I were calculated to examine heterogeneity. Potential sources of heterogeneity were investigated via subgroup and sensitivity analyses, and publication biases were estimated.A total of 30 randomized controlled trials with 1624 participants (828 in intervention groups and 796 in placebo groups) were included in this analysis. Subjects treated with probiotics demonstrated reduced total cholesterol and LDL cholesterol compared to control subjects by 7.8 mg/dL (95% CI: -10.4, -5.2) and 7.3 mg/dL (95% CI: -10.1, -4.4), respectively. There was no significant effect of probiotics on HDL cholesterol or triglycerides. The effect of probiotics on total cholesterol and LDL cholesterol depended on a variety of factors. The significant effects were greater for higher baseline total cholesterol levels, longer treatment durations, and certain probiotic strains. In addition, these associations seem stronger in studies supported by probiotics companies.The studies included in this meta-analysis showed significant heterogeneity as indicated by the Q statistics and I. In addition, industry sponsorship may affect study findings

    Folklore has suggested that consuming grapefruit may promote weight control. Sparse data exist to support this hypothesis, although there is some evidence of health promotion effects with regard to blood pressure control and modulation of circulating lipids. The aim of this randomized controlled trial was to prospectively evaluate the role of grapefruit in reducing body weight and blood pressure and in promoting improvements in the lipid profile in overweight adults (N = 74). Following a 3-week washout diet low in bioactive-rich fruits and vegetables, participants were randomized to either the control diet (n = 32) or daily grapefruit (n = 42) in the amount of one half of a fresh Rio-Red grapefruit with each meal (3× daily) for 6 weeks. No differences between group in weight, blood pressure, or lipids were demonstrated. Grapefruit consumption was associated with modest weight loss (-0.61 ± 2.23 kg, P = .097), a significant reduction in waist circumference (-2.45 ± 0.60 cm, P = .0002), and a significant reduction in systolic blood pressure (-3.21 ± 10.13 mm Hg, P = .03) compared with baseline values. Improvements were observed in circulating lipids of those consuming grapefruit, with total cholesterol and low-density lipoprotein significantly decreasing by -11.7 mg/dL (P = .002) and -18.7 mg/dL (P lipids, or blood pressure as compared with the control condition. However, the improvements in blood pressure and lipids demonstrated in the intervention group suggest that grapefruit should be further evaluated in the context of obesity and cardiovascular disease prevention.

    Increased levels of circulating soluble type of E-selectin (sE-selectin), neutrophil counts and blood pressure are associated with the development of cardiovascular diseases (CVD). In this study, we conducted a cross-sectional study of men who participated in health check-ups, and selected those who were not diagnosed with or being treated for metabolic diseases such as diabetes, hypertension and lipid abnormality according to the health check-ups. We measured their basic clinical parameters including blood pressure and neutrophil count, plasma sE-selectin concentration and lifestyle factors, and assessed their interrelations by multivariate linear regression (MLR) analysis. A total of 351 subjects aged 47.5±8.41 (range, 30-64) y were recruited. Significantly correlated with sE-selectin concentration were neutrophil count, diastolic blood pressure (DBP), and systolic blood pressure (SBP) (Pearson's correlation coefficient, 0.194, 0.220 and 0.175, respectively). MLR analysis showed that sE-selectin concentration was independently positively related with DBP and neutrophil count, whereas neutrophil count was positively associated with sE-selectin concentration but not DBP. DBP, but not SBP, was independently positively correlated with sE-selectin concentration but not neutrophil count. These results indicate that circulating sE-selectin concentration may be a biomarker for indicating subsequent development of metabolic diseases, in particular CVD, from a healthy state.

    It was found in experiments on guinea-pigs and white rats that 100-time weakened magnetic field of the earth considerably increased the activity of peroxide oxidation of lipids (POL) in tissues of inner organs. In the lungs, liver, kidneys, small intestine under the influence of hypogeomagnetic field (HGMF) we have observed reduction of ferment antioxidizing activity and of non-ferment mechanisms in the heart. The process is accompanied by reduction of cholesterol, phospholipids and triglycerides in guinea-pigs and increase of this indices in white rats after 5-day-long stay of animals in the hypogeomagnetic chamber. The data of experiments on white rats underlie a conclusion that the 5-day-long influence of HGMF promotes the change of the carbohydrate metabolism for lipid metabolism. The reaction of guinea-pigs on the stay under the weakened magnetic field of the earth displays in reduction of the level of lipid metabolism indices in the blood serum.

    Background We examined lipid peroxidation (LPO) in blood mononuclear cells (BMCs) and plasma, as a marker of oxidative damage, and its association to clinical symptoms in Fibromyalgia (FM) patients. Methods We conducted a case–control and correlational study comparing 65 patients and 45 healthy controls. Clinical parameters were evaluated using the Fibromyalgia Impact Questionnaire (FIQ), visual analogues scales (VAS), and the Beck Depression Inventory (BDI). Oxidative stress was determined by measuring LPO in BMCs and plasma. Results We found increased LPO levels in BMCs and plasma from FM patients as compared to normal control (P<0.001). A significant correlation between LPO in BMCs and clinical parameters was observed (r = 0.584, P<0.001 for VAS; r = 0.823, P<0.001 for FIQ total score; and r = 0.875, P<0.01 for depression in the BDI). We also found a positive correlation between LPO in plasma and clinical symptoms (r = 0.452, P<0.001 for VAS; r = 0.578, P<0.001 for FIQ total score; and r = 0.579, P<0.001 for depression in the BDI). Partial correlation analysis controlling for age and BMI, and sex, showed that both LPO in cells and plasma were independently associated to clinical symptoms. However, LPO in cells, but not LPO in plasma, was independently associated to clinical symptoms when controlling for depression (BDI scores). Discussion The results of this study suggest a role for oxidative stress in the pathophysiology of fibromyalgia and that LPO in BMCs rather than LPO in plasma is better associated to clinical symptoms in FM.

    The amino acid and lipid analysis on blood and liver and the amino acid analysis on urine gave irregular values for each determination. Therefore, the average values which were presented in the 1966 Technical Progress report (C00-1449-2) were not considered valid and were not submitted for publication. However, experiments on the in vivo conversion of 75 Se-labeled selenite-Se to urinary metabolites led to the observance of an unknown metabolite. This metabolite, which was different from the ordinary selenium analogues of sulfur, was designated as "U-1" (C00-1449-3). The use of the 59 Fe was involved in the study of the anemia of chronic selenium toxicity. The findings because of the labeled iron led to the conclusion that the anemia was from massive hemolysis (C00-1449-3).

    Objective:To investigate the effect of atorvastatin therapy on lipid levels of patients with transient ischemic attack (TIA).Methods:A total of 210 cases of TIA were selected as research subjects, and randomly divided into two groups with 105 cases in each group. Patients in the control group were treated with conventional therapy, and the observation group were treated with conventional treatment based on the use of atorvastatin. Incidence of cerebrovascular diseases, high-density lipoprotein (HDL), low density lipoprotein changes (LDL), triglycerides (TG) and total cholesterol (TC) and side effect of two groups were compared.Results:The incidence of cerebrovascular diseases was 10.48%, and significantly lower than the control group (P<0.05). The levels of HDL after treatment was significantly higher than the control group, and the levels of LDL, TG and TC after treatment were significantly lower than the control group (P<0.05). No adverse reaction occurred in both groups.Conclusion: Atorvastatin is safe and effective in prevention of TIA patients from cerebrovascular events, and can improve blood lipid indexes.

    Full Text Available Objective. To examine the associations of dietary glycemic index (GI and dietary glycemic load (GL with blood lipid concentrations and coronary heart disease (CHD in nondiabetic participants in the Health Worker Cohort Study (HWCS. Materials and Methods. A cross-sectional analysis was performed, using data from adults who participated in the HWCS baseline assessment. We collected information on participants' socio-demographic conditions, dietary patterns and physical activity via self-administered questionnaires. Dietary GI and dietary GL were measured using a validated food frequency questionnaire. Anthropometric and clinical measurements were assessed with standardized procedures. CHD risk was estimated according to the sex-specific Framingham prediction algorithms. Results. IIn the 5,830 individuals aged 20 to 70 who were evaluated, dietary GI and GL were significantly associated with HDL-C, LDL-C, LDL-C/HDL-C ratio, and triglycerides serum levels. Subjects with high dietary GI have a relative risk of 1.56 (CI 95%; 1.13–2.14, and those with high dietary GL have a relative risk of 2.64 (CI 95%; 1.15–6.58 of having an elevated CHD risk than those who had low dietary GI and GL. Conclusions. Our results suggest that high dietary GI and dietary GL could have an unfavorable effect on serum lipid levels, which are in turn associated with a higher CHD risk.

    Analysis of the epidemiological effects of overall dietary patterns offers an alternative approach to the investigation of the role of diet in CHD. We analysed the role of blood lipid-related dietary patterns using a two-step method to confirm the prospective association of dietary pattern with incident CHD. Analysis is based on 7314 participants of the Whitehall II study. Dietary intake was measured using a 127-item FFQ. Reduced rank regression (RRR) was used to derive dietary pattern scores using baseline serum total and HDL-cholesterol, and TAG levels as dependent variables. Cox proportional hazard regression was used to confirm the association between dietary patterns and incident CHD (n 243) over 15 years of follow-up. Increased CHD risk (hazard ratio (HR) for top quartile: 2.01 (95% CI 1.41, 2.85) adjusted for age, sex, ethnicity and energy misreporting) was observed with a diet characterised by high consumption of white bread, fried potatoes, sugar in tea and coffee, burgers and sausages, soft drinks, and low consumption of French dressing and vegetables. The diet-CHD relationship was attenuated after adjustment for employment grade and health behaviours (HR for top quartile: 1.81; 95% CI 1.26, 2.62), and further adjustment for blood pressure and BMI (HR for top quartile: 1.57; 95% CI 1.08, 2.27). Dietary patterns are associated with serum lipids and predict CHD risk after adjustment for confounders. RRR identifies dietary patterns using prior knowledge and focuses on the pathways through which diet may influence disease. The present study adds to the evidence that diet is an important risk factor for CHD.

Male New Zealand white (NZW rabbits were fed for 4 weeks on a normal diet containing pulp (NP or kernel oil (NK of CO while corn oil was used as control (NC. Total cholesterol (TC, HDL-C, LDL-c and triglycerides (TG levels were measured in this paper. Antioxidant enzymes (superoxide dismutase and glutathione peroxidise, thiobarbiturate reactive substances (TBARSs, and plasma total antioxidant status (TAS were also evaluated. Supplementation of CO pulp oil resulted in favorable changes in blood lipid and lipid peroxidation (increased HDL-C, reduced LDL-C, TG, TBARS levels with enhancement of SOD, GPx, and plasma TAS levels. Meanwhile, supplementation of kernel oil caused lowering of plasma TC and LDL-C as well as enhancement of SOD and TAS levels. These changes showed that oils of CO could be beneficial in improving lipid profile and antioxidant status as when using part of normal diet. The oils can be used as alternative to present vegetable oil.

    Introduction Coronary heart disease is one of the major causes of morbidity and mortality in current era. The roots of this epidemic have been traced to as early as foetal life by foetal origin hypothesis. There are a few studies which have compared the cord blood lipid profile of preterm and term babies and thereby leading a path to primordial prevention of chronic diseases. Aim To study cord blood lipid profile of preterm appropriate for gestational age and preterm small for gestational age neonates and compare atherogenic index of both groups. Materials and Methods This cross-sectional study was conducted in 109 preterm infants. Cord blood samples were collected from placental side of umbilical cord at birth and analyzed for lipid profile which includes serum cholesterol, triglycerides, Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL) and apolipoproteins which include ApoA1, Apo B. Results Preterm Small for Gestational Age (SGA) neonates had statistically significant higher values of triglycerides, Apo B and atherogenic index compared to preterm Appropriate for Gestational Age (AGA) neonates. Other measured lipid levels were not statistically significant, though the values were higher than reference ranges for term babies. Conclusion Prematurity as a factor associated with a more atherogenic lipid profile is re-affirmed and SGA as an additional risk factor has been proven giving scope for future research and primordial prevention.

    Full Text Available Abstract Background Altered levels of erythrocyte Na+K+-ATPase, atherogenic and anti-atherogenic lipid metabolites have been implicated in diabetic complications but their pattern of interactions remains poorly understood. This study evaluated this relationship in Nigerian patients with Type 1 diabetes mellitus. Methods A total of 34 consented Type 1 diabetic patients and age -matched 27 non-diabetic controls were enrolled. Fasting plasma levels of total cholesterol, triglycerides and HDL-cholesterol were determined spectrophotometrically and LDL-cholesterol estimated using Friedewald formula. Total protein content and Na+K+-ATPase activity were also determined spectrophotometrically from ghost erythrocyte membrane prepared by osmotic lysis. Results Results indicate significant (P +K+-ATPase activity in the Type 1 diabetic patients (0.38 ± 0.08 vs. 0.59 ± 0.07 uM Pi/mgprotein/h compared to the control but with greater reduction in the diabetic subgroup with poor glycemic control (n = 20 and in whom cases of hypercholesterolemia (8.8%, hypertriglyceridemia (2.9% and elevated LDL-cholesterol (5.9% each were found. Correlation analyses further revealed significant (P +K+-ATPase in this subgroup contrary to group with good glycemic control or non-diabetic subjects in which significant (P +K+-ATPase and HDL-C association were found (r = 0.427 - 0.489. The Na+K+-ATPase from the diabetic patients also exhibited increased sensitivity to digoxin and alterations in kinetic constants Vmax and Km determined by glycemic status of the patients. Conclusion It can be concluded that poor glycemic control evokes greater reduction in erythrocyte Na+K+-ATPase activity and promote enzyme-blood atherogenic lipid relationships in Type 1 diabetic Nigerian patients.

    establish the possible correlation between lipids, lipoproteins, apolipoproteins A-I and B, Lipoprotein(a and microalbuminuria in subjects with and without diabetes mellitus type 2 and high blood pressure. MATERIAL AND METHOD: The subjects, with age range from 40 to 65 years, were divided into five groups: 1. control (normal subjects, n = 16; 2. HAS (subjects with high blood pressure, n = 12; 3. DM (normotensive and normoalbuminuric patients with diabetes mellitus type 2, n = 7; 4. DM + HASnAlb (hypertensive and normoalbuminuric patients with diabetes mellitus type 2, n = 18 and 5. DM + HASmAlb (hypertensive and microalbuminuric patients with diabetes mellitus type 2, n = 9. RESULTS: Concerning to the lipid profile statistical differences were observed for LDL-C between the average of the group 5 compared to the averages of the other groups; for triglycerides among the groups 2, 4 and 5 compared to the group 1. For the total cholesterol, HDL-C, Lp(a and Apo A-I no significant difference was observed among the groups. Average values for Apo B for groups 4 and 5 presented significant difference compared to group 1. Positive correlation was observed between LDL-C and Apo B (r = 0,684; p < 0,0001 and HDL-C and Apo A-I (r = 0,374; p = 0,003, according to literature. CONCLUSION: Among all parameters assessment, LDL-C was the unique one that showed significant differences between the group 5, whose participants present both alterations (DM and HAS besides the microalbuminuria, related to other groups studied. This comes to suggest that the association between the two diseases allied to microalbuminuria may contribute to the dyslipidemia aggravation.

    Objectives: To assess the correlations between blood levels of sex steroid hormones and blood lipid profile or the degree of coronary artery stenosis in men with coronary artery disease (CAD). Methods: 111 men with stable CAD, aged 36-73 yrs, unselected for the coexisting clinical coronary risk factors were prospectively studied. Degree of coronary stenosis was assessed angiographically using different indices. Total cholesterol (T-Ch), high density lipoproteins cholesterol (HDL-Ch), low density lipoproteins cholesterol (LDL-Ch), triglicerydes (TG), testosterone, estradiol, dehydroepiandrosterone sulfate (DHEA-S), and sex hormone binding globulin (SHBG) were measured in the blood. Free testosterone index (FTI) was calculated. Results: A positive, significant correlations were found between blood concentrations of estradiol and T-Ch (r=0.29, p<0.01) or LDL-Ch (r=0.34, p<0.005) as well as between FTI and blood LDL-Ch (r=0.23, p<0.05). Blood level of estradiol negatively correlated with HDL-Ch/T-Ch ratio (r=-0.21, p<0.05). While blood levels of T-Ch correlated positively with 3 out of 5 applied here indices of coronary stenosis, blood LDL-Ch with two of them. In turn, blood level of testosterone negatively correlated with one index of coronary stenosis (r=-0.26, p<0.05). Conclusion: In men with CAD, plasma estradiol concentrations are predictive for T-Ch, LDL-Ch and HDL-Ch/TCh ratio, and FTI for LDL-Ch. Regression analyses indicated that while sex steroid hormones may predispose toward atherogenic lipid profile and are predictive for the number and degree of coronary artery stenosis, higher blood level of total testosterone was associated with the lower number of stenosis in the coronary arteries. Hence, endogenous testosterone may have beneficial effect on coronary arteries. PMID:23674975

    The ABO blood group system is the most important blood group system in clinical practice. The relationship between Plasmodium falciparum and ABO blood groups has been studied for many years. This study was undertaken to investigate the abilities of different blood group erythrocytes to support in vitro growth of P. falciparum parasites. P. falciparum parasites of four different strains (3D7, 7G8, Dd2 and RKL9) were co-cultured with erythrocytes of blood group 'A', 'B', 'O' (n = 10 for each) and 'O(h)' (Bombay group) (n = 7) for 5 days. Statistically significant differences were observed on the fourth day among the mean percent parasitemias of 'O', non-'O' ('A' and 'B') and 'O(h)' group cultures. The parasitemias of four strains ranged from 12.23 to 14.66, 11.68 to 13.24, 16.89 to 22.3, and 7.37 to 11.27 % in 'A', 'B', 'O' and Bombay group cultures, respectively. As the expression of H antigen decreased from 'O' blood group to 'A' and 'B' and then to Bombay blood group, parasite invasion (percent parasitemia) also decreased significantly (p group erythrocytes were virtually converted to Bombay group-like erythrocytes by the treatment of anti-H lectins extracted from Ulex europaeus seeds. Mean percent parasitemia of lectin-treated cultures on the fourth day was significantly lower (p Bombay group erythrocyte cultures, thus further strengthening the hypothesis.

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

    Full Text Available Background: Blood hyperviscosity has been acknowledged to be a complicating factor in polycythaemia and hyperproteinaemia. Hyperleucocytosis has also been implicated in hyperviscosity and may be a basis for therapeutic leukapheresis. Aims: This issue in the series seeks to determine the association and correlation between whole blood viscosity and white blood cell count (WBCC, with a view to advance the cause of a neglected clinical pathology index. Materials & Methods: Based on archived clinical pathology data, 10,857 cases that were concomitantly tested for full blood count and total proteins in the 2008 calendar year were audited for hyperleucocytosis. Whole blood viscosity level was determined and compared in the group with leucocytosis relative to the group with leucopenia and normal WBCC. The confounding effects of age, gender and red blood cell indices were evaluated. The correlation between whole blood viscosity and WBCC was also determined. Results: As a generalization, hypoviscosity is observed among individuals who presented hyperleucocytosis. There is no correlation (r = 0.20 between leucocytosis and blood viscosity. Conclusion: It is known that anaemia and thromboembolism, which can be associated with leucocytosis, predispose to hypoviscosity. The finding from this study provides evidence of association between hypoviscosity and leucocytosis. The absence of association and insignificant correlation between leucocytosis and hyperviscosity may be one explanation for ineffectiveness of therapeutic leukapheresis. Further, the non-correlation lends credence to specificity of blood viscosity, for which critical leucocytosis is not a substitute.

    Research highlights: {yields} Sifuvirtide interacts with erythrocyte and lymphocyte membrane in a concentration dependent manner by decreasing its dipole potential. {yields} Dipole potential variations in lipid vesicles show sifuvirtide's lipid selectivity towards saturated phosphatidylcholines. {yields} This peptide-membrane interaction may direct the drug towards raft-like membrane domains where the receptors used by HIV are located, facilitating its inhibitory action. -- Abstract: Sifuvirtide is a gp41 based peptide that inhibits HIV-1 fusion with the host cells and is currently under clinical trials. Previous studies showed that sifuvirtide partitions preferably to saturated phosphatidylcholine lipid membranes, instead of fluid-phase lipid vesicles. We extended the study to the interaction of the peptide with circulating blood cells, by using the dipole potential sensitive probe di-8-ANEPPS. Sifuvirtide decreased the dipole potential of erythrocyte and lymphocyte membranes in a concentration dependent manner, demonstrating its interaction. Also, the lipid selectivity of the peptide towards more rigid phosphatidylcholines was confirmed based on the dipole potential variations. Overall, the interaction of the peptide with the cell membranes is a contribution of different lipid preferences that presumably directs the peptide towards raft-like domains where the receptors are located, facilitating the reach of the peptide to its molecular target, the gp41 in its pre-fusion conformation.

    Objective To investigate the effect and possible mechanism of flavonoids extracted from Morus indica(FMI)on blood lipids and glucose.Methods The experimental hyperlipidemia-diabetic rats were induced by high-fat diet(HFD)and low dose of Streptozotocin(STZ).Flavonoids-treated rats were pretreated with FMI(50,100,and 200 mg/kg).The plasma,skeletal muscle,and livers were isolated for biochemical assays,HE staining,immunohistochemistry,and Western blotting analysis.Results The results showed that the body weight in flavonoidstreated(100 and 200 mg/kg)rats was reduced(P<0.05,0.01)compared to HFD-fed rats.FMI obviously reduced total cholesterol(P<0.01),triglycerides(P<0.05),and low-density lipoprotein cholesterol(P<0.05),increased high-density lipoprotein(P<0.05),and significantly decreased the atherosclerosis index(P<0.01);FMI(100 and 200 mg/kg)also down-regulated the elevation of blood glucose induced by STZ(P<0.05,0.01);At the meantime,FMI increased hepatic superoxide dismutase(SOD)activity and reduced hepatic malondialdehyde(MDA)content obviously.In addition,the results showed that the expression of hepatic CYP2E1 was markedly decreased while the expression of GLUT-4 in skeletal muscles was increased by FMI.Conclusion The above results demonstrate that the effect of FMI is related to its up-regulation of hepatic SOD activity,reduction of hepatic MDA content,down-regulation of hepatic CYP2E1 expression,and increase of GLUT-4 expression in skeletal muscle,which suggests that FMI may prevent or improve hyperlipidemia and hyperglycemia caused by an excessive HFD.

    The effect of syringotoxin (ST), a member of the cyclic lipodepsipeptides family (CLPs) produced by Pseudomonas syringae pv. syringae on the membrane permeability of human red blood cells (RBCs) and model bilayer lipid membranes (BLMs) was studied and compared to that of two recently investigated CLPs, syringomycin E (SRE) and syringopeptin 22A (SP22A) [Biochim. Biophys. Acta 1466 (2000) 79 and Bioelectrochemistry 52 (2000) 161]. The permeability-increasing effect of ST on RBCs was the least among the three CLPs. A time-dependent ST pore inactivation was observed on RBCs at 20 and 37 degrees C but not at 8 degrees C. From the kinetic model worked out parameters as permeability coefficient of RBC membrane for 86Rb(+) and pores mean lifetime were calculated. A shorter pores mean lifetime was calculated at 37 degrees C then at 20 degrees C, which gave us an explanation for the unusual slower rate of tracer efflux measured at 37 degrees C then that at 20 degrees C. The results obtained on BLM showed that the pore inactivation was due to a decrease in the number of pores but not to a change of their dwell time or conductance.

    The association between oral contraceptives and the modification of corporal weight and body fat distribution is controversial. The characteristics of the menstrual cycle, lipids and glucose levels were also analyzed. Thirty women who received ethinylestradiol 0.035 mg and norethindrone 0.400 mg for one year were studied. The following variables were analyzed every 3 months: weight, body mass index (BMI), hip perimeter, waist perimeter, waist-hip ratio (WHR), duration of menstrual cycle, quantity of uterine bleeding, as well as blood levels of cholesterol, triglycerides and glucose. Waist and hip perimeters increased during the third evaluation; as well as the BMI starting from the second evaluation. The triglycerides levels rose from the first evaluation. No modifications were found in the WHR, glucose and cholesterol levels and the duration of the menstrual cycle, but the quantity of uterine bleeding decreased from the third month. The oral contraceptive significantly increased BMI and triglycerides level, but no changes were detected in body fat distribution, cholesterol and glucose levels. Uterine bleeding decreased from the first evaluation.

    Full Text Available Aim. The main objective of this study was the comparative investigation of diverse lipid second messenger (LSM generation by human peripheral blood lymphocytes (HPBL at different (5, 10, 30 and 60 s time points of cell co-stimulation by anti-CD3 and anti-CD28 monoclonal antibodies in norm and breast cancer (BC. Methods. Ficoll-Hypaque gradient centrifugation. Results. The data obtained indicate that some mechanisms of LSM generation/utilization in stimulated crude HPBL were significantly altered in BC compared to norm. Particularly, the reliable generation of arachidonyl-1,2-diacylglycerol (1,2-DAG at the initial step (5 s of cell stimulation observed in norm was depressed in BC and reached the value below the basal level in unstimulated cells. It is important that the disturbances in 1,2-DAG formation in HPBL obtained from patients with BC were identical with those observed earlier in other forms of cancer. Conclusions. We conclude that the regularities revealed are common characteristics for all the types of malignancy studied and can be used as additional testing parameters for cancer definition and individual correction of the chemotherapy programs for disease treatment

    Idiopathic sudden sensorineural hearing loss (ISSHL) is a common otologic emergency whose cause is still unclear. The importance of blood lipids in the pathogenesis of ISSHL is widely reported in literature. In fact elevated levels of low density lipoprotein cholesterol (LDL), total cholesterol (TC) and apolipoprotein B (Apo-B) have been proposed as risk factors for this pathology. No correlation has been described between serum lipid parameters and the prognosis of ISSHL. Aim of the present study was to identify prognostic factors associated with hearing recovery in a group of patients affected by ISSHL. Ninety-four patients with the diagnosis of ISSHL hospitalized between March 2013 and October 2014 were included in this study. Patients' blood sampling and hearing assessments were carried out. Patients were divided into two groups as "recovered" and "unrecovered", according to their response to the treatment. We found a statistically significant higher level of total cholesterol in the unrecovered group compared to the recovered one (p = 0.03). None of the other routine laboratory parameters have shown a statistically significant difference between the patients successfully treated and patients with poor outcomes. Total cholesterol concentrations may be a prognostic factor for recovery in ISSHL and should be assessed together with routine tests in patients with this condition. The other routine laboratory parameters seem to have no effect on the development and prognosis of this pathology.

    Dried blood spot (DBS) sampling coupled to liquid chromatography-tandem mass spectrometry (LC-MS/MS) is a rapidly developing approach in the field of biopharmaceutical analysis. DBS sampling enables analysis of small sample volumes with high sensitivity and selectivity while providing a convenient easy to store and ship format. Lipid components that may be extracted during biological sample processing may result in matrix ionization effects and can significantly affect the precision and accuracy of the results. Glycerophosphocholines (GPChos), cholesterols and triacylglycerols (TAG) are the main lipid components that contribute to matrix effects in LC-MS/MS. Various organic solvents such as methanol, acetonitrile, methyl tertiary butyl ether, ethyl ether, dichloromethane and n-hexane were investigated for elution of these lipid components from DBS samples. Methanol extracts demonstrated the highest levels of GPChos whereas ethyl ether and n-hexane extracts contained less than 1.0 % of the GPChos levels in the methanol extracts. Ethyl ether extracts contained the highest levels of cholesterols and TAG in comparison to other investigated organic solvents. Acetonitrile is recommended as an elution solvent due to low lipid recoveries. Matrix effects resulted from different extracted lipid components should be studied and assessed carefully in DBS samples.

    Full Text Available Glucose and glycated hemoglobin (Hb in the blood of camel (Camelus dromedarius and cow (Bos taurus were analyzed and compared with human values. Camel displayed high blood glucose concentration (9.7±2.8 mM but a low level of glycated-Hb (3.4± 0.23%.Cow blood samples did not show sufficient variations in glucose concentrations (5.7±0.73 mM or glycated Hb levels (3.2± 0.11% compared to human values. The low glycation of camel Hb at higher glucose concentrations suggest that certain factors protect the Hb from glycation at high glucose concentrations. Camel Hb also exhibited a higher electrophoretic mobility than normal hemoglobin of human or cow. Camel Hb migrated at a rate corresponding to that of human Hb-C. Bioinformatics tools were used to explore the biochemical basis for the difference in camel Hb migratory position and its apparent resistance to glycation.

    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.

  20. Compartmentalisation of cAMP-dependent signalling in blood platelets: The role of lipid rafts and actin polymerisation.

    Science.gov (United States)

    2015-01-01

    Prostacyclin (PGI2) inhibits blood platelets through the activation of membrane adenylyl cyclases (ACs) and cyclic adenosine 3',5'-monophosphate (cAMP)-mediated signalling. However, the molecular mechanism controlling cAMP signalling in blood platelet remains unclear, and in particular how individual isoforms of AC and protein kinase A (PKA) are coordinated to target distinct substrates in order to modulate platelet activation. In this study, we demonstrate that lipid rafts and the actin cytoskeleton may play a key role in regulating platelet responses to cAMP downstream of PGI2. Disruption of lipid rafts with methyl-beta-cyclodextrin (MβCD) increased platelet sensitivity to PGI2 and forskolin, a direct AC cyclase activator, resulting in greater inhibition of collagen-stimulated platelet aggregation. In contrast, platelet inhibition by the direct activator of PKA, 8-CPT-6-Phe-cAMP was unaffected by MβCD treatment. Consistent with the functional data, lipid raft disruption increased PGI2-stimulated cAMP formation and proximal PKA-mediated signalling events. Platelet inhibition, cAMP formation and phosphorylation of PKA substrates in response to PGI2 were also increased in the presence of cytochalasin D, indicating a role for actin cytoskeleton in signalling in response to PGI2. A potential role for lipid rafts in cAMP signalling is strengthened by our finding that a pool of ACV/VI and PKA was partitioned into lipid rafts. Our data demonstrate partial compartmentalisation of cAMP signalling machinery in platelets, where lipid rafts and the actin cytoskeleton regulate the inhibitory effects induced by PGI2. The increased platelet sensitivity to cAMP-elevating agents signalling upon raft and cytoskeleton disruption suggests that these compartments act to restrain basal cAMP signalling.

    To evaluate if pRCCs demonstrate intracellular lipid (i-lipid) at chemical-shift (CS) MRI, and assess T2W-MRI and pathologic characteristics. Sixty-two patients with a pRCC diagnosis underwent MRI over 11 years (IRB-approved). Two radiologists independently assessed for presence of i-lipid on CS-MRI and homogeneity on T2W-MRI. Inter-observer agreement was assessed via an intraclass correlation and results were compared using the Chi-square test. Discordant cases were reviewed to establish consensus. T2W SI-ratios (SI.tumor/SI.kidney) and CS-SI index were compared using independent t-tests and Spearman correlation. Two pathologists re-evaluated the histopathology. Nine of the 62 pRCCs (14.5 %) demonstrated i-lipid; agreement was moderate (ICC = 0.63). Pathology review depicted clear cells in four tumours and foamy histiocytes in five tumours. 25.8-35.4 % (ICC = 0.65) of tumours were homogeneous on T2W-MRI. No pRCC with i-lipid was considered homogeneous (p = 0.01-0.04). Overall, T2W SI-ratio and CS-SI index were 0.89 (±0.29) and -3.63 % (-7.27 to 11.42). pRCC with i-lipid had significantly higher T2W SI-ratio (p = 0.003). There was a correlation between the CS-SI index and T2W SI-ratio, (r = 0.44, p < 0.001). Intracellular lipid is uncommonly detected in pRCCs due to clear cell changes and foamy histiocytes. These tumours are associated with heterogeneously-increased SI in T2W-MRI. (orig.)

    Regularities of biologically active lipid metabolites formation in dynamics (5, 10, 30, 60 s) by phorbol 12-miristate 13-acetate stimulation in [14C]palmitic acid have been investigated in normal and leukemia peripheral blood lymphocytes prelabeled with [14C]palmitate. In normal cells there was two-phase formation of 1,2-diacylglycerol (5, 30 s), lysophosphatidylcholine (10, 60 s), as well as free palmitic acid at 10 s of stimulation. Under the identical experimental conditions there was inhibition of investigated lipid release processes at early (5 and 10 s) stages of stimulation of leukemic lymphocytes. At later (30, 60 s) terms of these lymphocytes the activation, basically, similar to norm changes in the formation of palmitic acid-containing metabolites except free palmitic acid (the level of which raised only at 60 second of the post-stimulation) was found. Various protein kinases C are involved in the regulation of investigated lipid levels at certain stages of signal transduction both in norm, and in blast cells. Short-term (5, 10 s) activations of healthy donors lymphocytes are coupled to functioning of Ca2+-independent isoforms of protein kinase C. The inhibition of this protein kinase C in leukemic cells leads to normalization of the investigated lipid release. The data obtained suggests disorders of early membrane-bound reactions in agonist - and a protein kinase C-mediated processes of formation palmitic acid-containing lipid metabolites in the leukemic cells in comparison with the norm.

    Full Text Available Abstract Background Respiratory Syncytial Virus (RSV infection is usually restricted to the respiratory epithelium. Few studies have documented the presence of RSV in the systemic circulation, however there is no consistent information whether virus detection in the blood correlates with disease severity. Methods Balb/c mice were inoculated with live RSV, heat-inactivated RSV or medium. A subset of RSV-infected mice was treated with anti-RSV antibody 72 h post-inoculation. RSV RNA loads were measured by PCR in peripheral blood from day 1-21 post-inoculation and were correlated with upper and lower respiratory tract viral loads, the systemic cytokine response, lung inflammation and pulmonary function. Immunohistochemical staining was used to define the localization of RSV antigens in the respiratory tract and peripheral blood. Results RSV RNA loads were detected in peripheral blood from day 1 to 14 post-inoculation, peaked on day 5 and significantly correlated with nasal and lung RSV loads, airway obstruction, and blood CCL2 and CXCL1 expression. Treatment with anti-RSV antibody reduced blood RSV RNA loads and improved airway obstruction. Immunostaining identified RSV antigens in alveolar macrophages and peripheral blood monocytes. Conclusions RSV RNA was detected in peripheral blood upon infection with live RSV, followed a time-course parallel to viral loads assessed in the respiratory tract and was significantly correlated with RSV-induced airway disease.

    Chromium(III) is considered as an essential element for carbohydrate and lipid metabolism. The aim of this clinical study was to evaluate the efficacy of Cr brewer's yeast supplementation on body mass, carbohydrate, lipids and mineral indices in type 2 diabetic patients. Twenty adult type 2 diabetic subjects (11 males and 9 females aged 37-63) were supplemented with Cr brewer's yeast in dosages of 500 μg Cr/person/day or placebo for 8 weeks in a double-blind, placebo-controlled crossover design. It was found that supplemental Cr did not affect body mass, blood lipid profile, resistin levels, and the serum and hair Zn, Fe, and Cu levels, but increased serum Cr (by 116%) and hair Cr (by 20.6%) concentrations and improved some blood carbohydrate indices (significant increase in the β cell function index by 18.8%) in type 2 diabetic patients. In conclusion, Cr brewer's yeast has a weak hypoglycemic potential, but does not affect body mass, blood biochemical profile, and microelement levels in type 2 diabetic subjects.

    Full Text Available Several epidemiologic studies have reported that exposure to noise is associated with cardiovascular disease. The increased body weight is often associated with metabolic as well as increased blood pressure. The aim of this study is to investigate the correlation between the elevation of blood pressure and serum leptin hormones due to the effects of noise in the work place. A total of 80 volunteer males where included in this study with an age range between of 20 and 45 years, they were divided in two groups equally, the 1 st group were exposed to noise in the workplace while the 2 nd group were not. The individual noise exposure was determined by using a sound level meter. The range of noise was 80-100 dBA. Body Mass Index was also taken for each individual by a standard measure, blood pressure was measured by OMRON sphygmomanometer and serum leptin was measured through venous blood sample analysis enzyme linked immunosorbent assay. Spearman rank order correlation was used to examine the correlations between Blood pressure value (Systolic, Diastolic and Leptin. All the relationships between parameters showed a positive correlation. Systolic and diastolic blood pressure values had a significant correlation to leptin hormone level in comparison to the control. There was a significant relation between leptin and blood pressure. leptin effects on the sympathetic nervous system may provide a partial explanation. Therefore, Leptin might have diverse cardiovascular actions.

    A simple and fast lipid extraction method from human blood plasma and urine is introduced in this study. The effective lipid extraction from biological systems with a minimization of the matrix effect is important for the successful qualitative and quantitative analysis of lipids in liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). The method described here is based on the modification of the quick, easy, cheap, effective, rugged and safe (QuEChERS) extraction method, which was originally developed for pesticide residue analysis in food, for the purpose of isolating lipids from biological fluids. Applicability of QuEChERS method for lipids was evaluated by varying organic solvents for the extraction/partitioning of lipids in MgSO4/CH3COONa for the removal of water and by varying sorbents (primary secondary amines, graphitized carbon black, silica, strong anion exchange resins and C18 particles) for the dispersive solid-phase extraction (dSPE) step. This study shows that 2:1 (v/v) CHCl3/CH3OH is effective in the extraction/partitioning step and that 50mg of C18 particles (for 0.1mL plasma and 1mL of urine) are more suitable for sample cleanup for the dSPE step of the QuEChERS method. Matrix effects were calculated by comparing the recovery values of lipid standards spiked to both plasma and urine samples after extraction with those of the same standards in a neat solution using nanoflow LC-ESI-MS/MS, resulting in improved MS signals due to the decrease of the ion suppression compared to the conventional Folch method. The modified QuEChERS method was applied to lipid extracts from both human urine and plasma samples, demonstrating that it can be powerfully utilized for high-speed (lipids compared to the Folch method, with equivalent or slightly improved results in lipid identification using nLC-ESI-MS/MS.

    This study was undertaken to determine the effects of canola oil on platelet characteristics, blood lipids and growth in exclusively formula-fed piglets. Piglets were fed from birth to 10 or 18 d with formula containing 51% energy from fat, with 100% fat as canola or soybean oil; 26% soybean, 59% high oleic acid sunflower and 12% flax oil (canola mimic); or 26% canola (canola blend) or soybean (soybean blend) with high oleic acid sunflower, palm and coconut oil. The canola mimic provided similar carbon chain 16 and 18 fatty acids without the sterol or 20:1 and erucic acid (22:1) of canola oil. The oil blends provided formula resembling infant formulas but with higher 16:0 and lower unsaturated fatty acid levels than in canola or soybean oil. Body weight, weight gain and heart and liver weight were not different after 10 or 18 d feeding canola when compared to soybean oil alone or blended oil formulas. Piglets fed formulas with 100% canola oil had lower platelet counts than piglets fed formula soybean oil or the canola oil mimic. Platelet counts were lower, and platelet distribution width and volume were higher, when formulas with 100% canola or soybean rather than the blended oil formulas were fed. The results show that formula fat composition influences the developing hematological system and that canola oil suppresses the normal developmental increase in platelet count in piglets by a mechanism apparently unrelated to the formula 16:0, 18:1, 18:2(n-6) or 18:3(n-3), or plasma phospholipid 20:4(n-6) or 20:5(n-3).

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

    Objective: To study the correlativity between blood telomerase activity and Non-small cell lung carcinoma (NSCLC) through relative quantitative analysis of telomerase activity. Methods: Thirty-eight NSCLC and 25 inpatients with benign lung disease were selected. Telomerase repeat amplification protocol was adopted. PCR products were assayed with ELISA. Results: (a) Blood telomerase activity during operation was higher than that before or after operation (P0.05). (c) Blood telomerase activity of adenocarcinoma during and after operation was higher than that before operation (P0.05). Conclusion: The qualitative assay of blood telomerase activity can be adopted as an assistant index for diagnosis of NSCLC. Postoperative blood telomerase activity of adenocarcinoma is higher than that of squamous carcinoma. It may be an evidence for the likelihood of adenocarcinoma to metastase through blood. Blood telomerase activity increases significantly during operation, suggesting that operation may cause more cancer cells entering into circulation.

    A hallmark of atopic eczema (AE) is skin barrier dysfunction. Lipids in the stratum corneum (SC), primarily ceramides, fatty acids, and cholesterol, are crucial for the barrier function, but their role in relation to AE is indistinct. Filaggrin is an epithelial barrier protein with a central role in the pathogenesis of AE. Nevertheless, the precise causes of AE-associated barrier dysfunction are largely unknown. In this study, a comprehensive analysis of ceramide composition and lipid organization in nonlesional SC of AE patients and control subjects was performed by means of mass spectrometry, infrared spectroscopy, and X-ray diffraction. In addition, the skin barrier and clinical state of the disease were examined. The level of ceramides with an extreme short chain length is drastically increased in SC of AE patients, which leads to an aberrant lipid organization and a decreased skin barrier function. Changes in SC lipid properties correlate with disease severity but are independent of filaggrin mutations. We demonstrate for the first time that changes in ceramide chain length and lipid organization are directly correlated with the skin barrier defects in nonlesional skin of AE patients. We envisage that these insights will provide a new therapeutic entry in therapy and prevention of AE.

    Background: Prediabetes is a high-risk condition for type 2 diabetes mellitus. The growing prevalence of diabetes emphasizes on the necessity of concentrating on various strategies to prediabetes prevention and management. Probiotics as a group of functional foods might exert antidiabetic effects. This study aimed to assess the effects of probiotic administration on blood lipid profile and blood pressure in patients with prediabetes. Methods: This randomized controlled trial consisted of 60 prediabetic patients, aged 25-65 years old, that were randomly assigned to the intervention (receiving 500 mg probiotic capsules, n = 30) or control group (receiving placebo, n = 30) for 8-week period. Demographic and anthropometric data were collected at baseline. Blood samples were collected at baseline and after 8 weeks for biochemical measurements. Blood pressure was measured at the baseline an after 8 weeks of intervention. Data regarding dietary intakes and physical activity were also collected during the study. We used SPSS software version 16 (SPSS Inc. Chicago, USA) for data analyzing. Results: Probiotic supplementation did not contribute to significant changes in total cholesterol, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, Triglycerides (TG), TG/LDL and LDL/HDL ratios, after 8 weeks. After adjusting for potential confounders, HDL-cholesterol reduced significantly in the placebo group compared with probiotic group. Percent change in systolic blood pressure was significantly different in the probiotic group in comparison with a placebo group (–3.10 ± 2.22 vs. 3.24 ± 1.96, P = 0.01), although this significance did not exist anymore after adjusting for confounders (P > 0.05). Conclusions: Our study showed that probiotics did not have significant effects on lipid markers although they had positive effects on systolic blood pressure. PMID:25400881

    Nisin and related lantibiotics kill bacteria by pore formation or by sequestering lipid II. Some lantibiotics sequester lipid II into clusters, which were suggested to kill cells through delocalized peptidoglycan synthesis. Here, we show that cluster formation is always concomitant with (i) membrane pore formation and (ii) membrane depolarization. Nisin variants that cluster lipid II kill L-form bacteria with similar efficiency, suggesting that delocalization of peptidoglycan synthesis is not the primary killing mechanism of these lantibiotics.

    Full Text Available Aminoamide local anesthetics induce vasoconstriction in vivo and in vitro. The goals of this in vitro study were to investigate the potency of local anesthetic-induced vasoconstriction and to identify the physicochemical property (octanol/buffer partition coefficient, pKa, molecular weight, or potency of local anesthetics that determines their potency in inducing isolated rat aortic ring contraction. Cumulative concentration-response curves to local anesthetics (levobupivacaine, ropivacaine, lidocaine, and mepivacaine were obtained from isolated rat aorta. Regression analyses were performed to determine the relationship between the reported physicochemical properties of local anesthetics and the local anesthetic concentration that produced 50% (ED50 of the local anesthetic-induced maximum vasoconstriction. We determined the order of potency (ED50 of vasoconstriction among local anesthetics to be levobupivacaine > ropivacaine > lidocaine > mepivacaine. The relative importance of the independent variables that affect the vasoconstriction potency is octanol/buffer partition coefficient > potency > pKa > molecular weight. The ED50 in endothelium-denuded aorta negatively correlated with the octanol/buffer partition coefficient of local anesthetics (r2=0.9563; P<0.001. The potency of the vasoconstriction in the endothelium-denuded aorta induced by local anesthetics is determined primarily by lipid solubility and, in part, by other physicochemical properties including potency and pKa.

    Modern ultrasound scanners estimate the blood velocity by tracking the movement of the blood scatterers along the ultrasound beam. This is done by emitting pulsed ultrasound fields and finding the shift in position from pulse to pulse by correlating the received signals. Only the velocity component...... along the beam direction is found, and this is a serious limitation in the current scanners, since most blood vessels are parallel to the skin surface. A method to find the velocity across the vessel has been suggested by Bonnefous (1988). Here a number of parallel receive beams are measured and used...... or across it or in any direction to the beam. The focused lines, thus, follow the flow and a cross-correlation of lines from different pulses can find the movement of the blood particles between pulse emissions and, thus, the blood velocity. The new approach is investigated using the Field II simulation...

    The correlation between the degrees of integrity and cohesion in healthy human Stratum corneum (SC) and the properties of the SC lipid matrix could be examined non-invasively in vivo using ATR-FTIR spectroscopy and measurements of pH, conductance, and transepidermal water loss (TEWL) taken in the course of tape-stripping. The change of TEWL following the removal of a SC layer with a predefined thickness served as a measure for the SC integrity, and the amount of protein removed by predefined number of tapes - as a measure for the SC cohesion. The extent of lipids organized in orthorhombic lattices and the pH in the inner SC emerged as the main factors that determine the degree of integrity. The amounts and molecular organization of the SC lipids did not correlate with the degree of cohesion, while the pH and the hydration of SC correlated well with the degree of cohesion in the superficial but not in the inner SC layers. This study evidenced the variability of SC integrity and cohesion existing in healthy human skin, demonstrated the importance of the lipid molecular organization for the SC integrity, and illustrated the limitations in the determination the degree of corneodesmolysis in SC based only on the protein content of tape-strips.

    Objective: To explore the correlation between disturbance of estrogen and lipid metabolism and occurrence and progression of endometrial adenocarcinoma so as to seek the early-warning markers for endometrial adenocarcinoma. Methods:Seventy-nine patients initially diagnosed as endometrial adenocarcinoma were collected as research group, and 70 healthy people with normal endometrium at the same term were as control group. The levels of fasting blood glucose (FBG), serum total triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), estradiol (E2), progesterone (P), testosterone (T) and fasting insulin (FINS) were all detected in two groups, and the risk factors of endometrial carcinoma were analyzed by non-conditional Logistic regression model. Results: The age, body mass index (BMI), FINS and homeostasis model assessment for insulin resistance (HOMA-IR) in research group were all higher than those in control group dramatically (P=0.0000). The level of HDL-C was signiifcantly lower, while that of E2 was markedly higher in premenopausal patients in research group than in control group, and there was statistical significance (P=0.0000). The levels of TC, TG, LDL-C, E2 and T in menopausal patients were all higher, while that of HDL-C was lower in research group than in control group, and all the differences were statistically signiifcant (P<0.05). The risk factors of endometrial adenocarcinoma included increase of BMI, E2, TG, and FIN as well as presence of HOMA-IR (OR=6.535,P=0.010; OR=7.796,P=0.011; OR=4.371,P=0.006; OR=6.392,P=0.020; OR=3.711, P=0.021). Conclusion:Women with increase of BMI, E2, TG, and FIN as well as presence of HOMA-IR can be considered as a high-risk population for developing endometrial adenocarcinoma.

    Serum concentrations of total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) are among the most important risk factors for coronary artery disease (CAD) and are targets for therapeutic intervention. We screened the genome for common variants associated with serum lipids in >100,000 individuals of European ancestry. Here we report 95 significantly associated loci (P < 5 × 10-8), with 59 showing genome-wide significant association with lipid traits for the first time. The newly reported associations include single nucleotide polymorphisms (SNPs) near known lipid regulators (e.g., CYP7A1, NPC1L1, and SCARB1) as well as in scores of loci not previously implicated in lipoprotein metabolism. The 95 loci contribute not only to normal variation in lipid traits but also to extreme lipid phenotypes and impact lipid traits in three non-European populations (East Asians, South Asians, and African Americans). Our results identify several novel loci associated with serum lipids that are also associated with CAD. Finally, we validated three of the novel genes—GALNT2, PPP1R3B, and TTC39B—with experiments in mouse models. Taken together, our findings provide the foundation to develop a broader biological understanding of lipoprotein metabolism and to identify new therapeutic opportunities for the prevention of CAD.

    Full Text Available Although altered lipid metabolism has been extensively implicated in the pathogenesis of Alzheimer disease (AD through cell biological, epidemiological, and genetic studies, the molecular mechanisms linking cholesterol and AD pathology are still not well understood and contradictory results have been reported. We have used a Mendelian randomization approach to dissect the causal nature of the association between circulating lipid levels and late onset AD (LOAD and test the hypothesis that genetically raised lipid levels increase the risk of LOAD.We included 3,914 patients with LOAD, 1,675 older individuals without LOAD, and 4,989 individuals from the general population from six genome wide studies drawn from a white population (total n=10,578. We constructed weighted genotype risk scores (GRSs for four blood lipid phenotypes (high-density lipoprotein cholesterol [HDL-c], low-density lipoprotein cholesterol [LDL-c], triglycerides, and total cholesterol using well-established SNPs in 157 loci for blood lipids reported by Willer and colleagues (2013. Both full GRSs using all SNPs associated with each trait at p<5×10-8 and trait specific scores using SNPs associated exclusively with each trait at p<5 × 10-8 were developed. We used logistic regression to investigate whether the GRSs were associated with LOAD in each study and results were combined together by meta-analysis. We found no association between any of the full GRSs and LOAD (meta-analysis results: odds ratio [OR]=1.005, 95% CI 0.82-1.24, p = 0.962 per 1 unit increase in HDL-c; OR=0.901, 95% CI 0.65-1.25, p=0.530 per 1 unit increase in LDL-c; OR=1.104, 95% CI 0.89-1.37, p=0.362 per 1 unit increase in triglycerides; and OR=0.954, 95% CI 0.76-1.21, p=0.688 per 1 unit increase in total cholesterol. Results for the trait specific scores were similar; however, the trait specific scores explained much smaller phenotypic variance.Genetic predisposition to increased blood cholesterol and

    This study seeks correlations between the molecular structures of cationic and neutral lipids, the lipid phase behavior of the mixed-lipid lipoplexes they form with plasmid DNA, and the transfection efficacy of the lipoplexes. Synthetic cationic pyridinium lipids were co-formulated (1:1) with the cationic lipid 1,2-dimyristoyl-sn-glycero-3-ethylphosphocholine (EPC), and these lipids were co-formulated (3:2) with the neutral lipids 1,2-dioleoyl-sn-glycero-3-phosphatidylethanolamine (DOPE) or cholesterol. All lipoplex formulations exhibited plasmid DNA binding and a level of protection from DNase I degradation. Composition-dependent transfection (beta-galactosidase and GFP) and cytotoxicity was observed in Chinese hamster ovarian-K1 cells. The most active formulations containing the pyridinium lipids were less cytotoxic but of comparable activity to a Lipofectamine 2000™ control. Molecular structure parameters and partition coefficients were calculated for all lipids using fragment additive methods. The derived shape parameter values correctly correlated with observed hexagonal lipid phase behavior of lipoplexes as derived from small-angle X-ray scattering experiments. A transfection index applicable to hexagonal phase lipoplexes derived from calculated parameters of the lipid mixture (partition coefficient, shape parameter, lipoplex packing) produced a direct correlation with transfection efficiency.

    Synaptosomal-associated protein 23 (SNAP23) is involved in microvesicle trafficking and exocytosis in various cell types, but its functional role in blood pressure (BP) regulation has not yet been defined. Here, we found that lipid raft SNAP23 expression was much lower in vascular smooth-muscle cells (VSMCs) from spontaneously hypertensive rats (SHR) than in those from normotensive Wistar-Kyoto (WKY) rats. This led us to investigate the hypothesis that this lower expression may be linked to the spontaneous hypertension found in SHR. The expression level of lipid raft SNAP23 and the fluidity in the plasma membrane of VSMCs were lower in SHR than in WKY rats. Cholesterol content in the VSMC membrane was higher, but the secreted cholesterols found in VSMC-conditioned medium and in the blood serum were lower in SHR than in WKY rats. SNAP23 knockdown in WKY rat VSMCs reduced the membrane fluidity and increased the membrane cholesterol level. Systemic overexpression of SNAP23 in SHR resulted in an increase of cholesterol content in their serum, a decrease in cholesterol in their aorta and the reduction of their BP. Our findings suggest that the low expression of the lipid raft SNAP23 in VSMCs might be a potential cause for the characteristic hypertension of SHR.

    Background: The impact of honey or vinegar on several metabolic abnormalities has been studied separately, a mixture of these two ingredients known as honey vinegar syrup (HVS) has not been investigated previously so far. The aim of this study was to assess the impact of HVS consumption (Iranian's traditional syrup) on glycemic parameters and lipid profiles in healthy individuals. Methods: We conducted a 4-week, randomized, controlled, parallel study consisting of two groups of nonobese healthy volunteers. All subjects were asked to stay on their normal diet. Intervention group (n = 36) received a cup of HVS daily in the evening snack for 4-week (250 cc syrup contains 21.66 g honey vinegar). Assessments of fasting blood sugar (FBS), insulin, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were conducted at the baseline and after 4-week of study. Results: We observed no significant effect of HVS on FBS, HOMA-IR, LDL-C and TG. A significant effect of HVS was found on increasing fasting insulin and HOMA-IR and reduction in TC level only in intervention group (Δ =3.39 P = 0.01, Δ =1.65 P = 0.03, Δ = −9.43 P = 0.005, respectively). Changes of FBS, TG and LDL-C were 1.83 mg/dl, −1.53 mg/dl and − 3.99 mg/dl respectively in the intervention group. These changes were not significant. An unfavorable and significant reduction in HDL-C level was also observed between two groups (Δ = −4.82 P < 0.001 in the intervention group). Conclusions: Honey vinegar syrup increased fasting insulin level and decreased TC level in the intervention group. HVS had an unfavorable effect on HDL-C level. Further prospective investigations are warranted to confirm these findings. PMID:25709798

    Full Text Available Yongxue Zhao, Long Wang, Mina Yan, Yanling Ma, Guangxi Zang, Zhennan She, Yihui DengCollege of Pharmacy, Shenyang Pharmaceutical University, Shenyang, Liaoning, People’s Republic of ChinaAbstract: Surface modification of nanocarriers with amphiphilic polymer polyethylene glycol (PEG, known as PEGylation, is regarded as a major breakthrough in the application of nanocarriers. However, PEGylated nanocarriers (including liposomes and polymeric nanoparticles induce what is referred to as the “accelerated blood clearance (ABC phenomenon” upon repeated injection and consequently they lose their sustained circulation characteristics. Despite this, the present authors are not aware of any reports of accelerated clearance due to repeated injection for PEGylated solid lipid nanoparticles (SLNs, another promising nanocarrier. This study investigated the pharmacokinetics of PEGylated SLNs upon repeated administration in mice; moreover, the impact of circulation time on the induction of the ABC phenomenon was studied in beagles for the first time. The ABC index, selected as the ratio of the area under the concentration-time curve from time 0 to the last measured concentration of a second injection to that of the first injection, was used to evaluate the extent of this phenomenon. Results showed that the PEGylated SLNs exhibited accelerated clearance from systemic circulation upon repeated injection, both in mice and in beagles, and the ratio for the different time intervals, which showed that the ABC index exhibited significant difference within 30 minutes following the second injection, was good enough to evaluate the magnitude of ABC. This ABC index indicated that the 10 mol% PEG SLNs with a suitable prolonged circulation time induced the most marked ABC phenomenon in this research. This study demonstrated that, like PEGylated nanocarriers such as liposomes and polymeric nanoparticles, PEGylated SLNs induced the ABC phenomenon upon repeated injection

    Diabetes mellitus has been suggested to be the most common metabolic disorder associated with magnesium deficiency, having 25% to 39% prevalence. This deficit could be associated with the development of late diabetic complications, especially macroangiopathy.We aimed to evaluate the status of serum Mg in children with type 1 diabetes and assess its relation to glycemic control and lipid profile.We included 71 Egyptian children with type 1diabetes having their follow-up at Pediatric Endocrinology outpatient clinic, Zagazig University Hospital and 71 age- and sex-matched control. We measured Serum magnesium, HbA1c, and lipid profile in all study subjects.Diabetic children had significantly lower serum magnesium level compared to control children (1.83 ± .27 mg/dL in diabetic children versus 2.00 ± .16 mg/dL in control children). Taking cut-off level of serum magnesium magnesium group, as it is mean ± SD was 11.93 ± 3.17 mg/dL in group I versus 8.92 ± 0.93 mg/dL in the normomagnesemic group. Serum magnesium was found to be positively correlated with HDL (P magnesium was frequently low in Egyptian children with type 1 diabetes and it is correlated with HbA1c and with lipid profile. Hypomagnesemia was more evident in patients with poor diabetic control and those with higher atherogenic lipid parameters. We suggest that low serum magnesium may be included in pathogenesis of poor glycemic control and abnormal lipid profile in children with type 1 diabetes. We need to perform further studies on giving magnesium supplements in diabetic children with hypomagnesemia to observe the effect of correction of serum magnesium on glycemic control, lipid profile, and the risk of diabetic complications.

    Full Text Available Abstract Background Depression is known to be a risk factor for cardiovascular diseases but the underlying mechanisms remain unclear. Since recent preclinical evidence suggests that endogenous agonists of cannabinoid receptors (endocannabinoids are involved in both cardiovascular function and depression, we asked whether endocannabinoids correlated with either in humans. Results Resting blood pressure and serum content of endocannabinoids in ambulatory, medication-free, female volunteers with depression (n = 28 and their age- and ethnicity-matched controls (n = 27 were measured. In females with depression, both diastolic and mean arterial blood pressures were positively correlated with serum contents of the endocannabinoids, N-arachidonylethanolamine (anandamide and 2-arachidonoylglycerol. There was no correlation between blood pressure and endocannabinoids in control subjects. Furthermore, depressed women had significantly higher systolic blood pressure than control subjects. A larger body mass index was also found in depressed women, however, it was not significantly correlated with serum endocannabinoid contents. Conclusions This preliminary study raises the possibility that endocannabinoids play a role in blood pressure regulation in depressives with higher blood pressure, and suggests an interrelationship among endocannabinoids, depression and cardiovascular risk factors in women.

    Full Text Available Background: Aging is a condition of chronic inflammation. In healthy Australians ≥64 years, the primary aim was to determine whether four servings/week of mixed fish (FISH improves serum cytokines (i.e. C-reactive protein (CRP, IL-1, IL-6, TNF-α compared to a diet low in fish (<1 serving/week, CONTROL; the secondary aims were to assess the effect of the diet on blood pressure and serum lipids (TC, HDL-C, TG, calculated LDL-C. Methods: An 8-week randomized, parallel study, stratified by CRP (<3 mg/L vs. ≥3 mg/L on entry to the study. Compliance was measured using 3-day weighed food records in weeks 1 and 7 of the study. A 12-h fasting blood sample was taken at baseline and 8-weeks for erythrocyte fatty acids as confirmation of compliance, and measurement of serum cytokines and lipids. Blood pressure was measured at both time points. Results: Eighty participants completed the study (mean (SD age: 69.6 (5.8 years. During week 1 of the study, mean ± SEM daily dietary intake of very long chain omega-3 polyunsaturated fatty acids (VLCN n-3 PUFA in FISH vs. CONTROL was 1,676±129 mg vs. 27±5 mg (p<0.001. Mean (SD gram intake of study fish and meat was 121 (45 g and 123 (78 g, for those allocated to FISH and CONTROL, respectively. Mean ± SEM percentage VLCN n-3 PUFA in erythrocytes at 8-weeks was higher in those allocated to FISH vs. CONTROL (10.2±0.2% vs. 8.2±0.3%, p<0.001. There was no between-group difference in CRP (n=80, IL-1β (n=33 or IL-6 (n=21 concentrations, blood pressure, or lipids, at 8-weeks. Conclusions: Eight weeks consumption of four servings/week fish did not affect serum cytokine concentrations, blood pressure or lipids compared to a diet low in fish. In healthy older adults with low inflammatory burden, our results do not support that short-term consumption of mixed fish has a beneficial effect on selected cardiovascular biomarkers.

    Abstract Background: Atorvastatin decreases blood lipids but is associated with side effects. Zhibitai is a traditional Chinese medicine used to treat blood lipid disorders. The objective of this study is to evaluate the lipid-lowering effect, antiinflammatory effect, and adverse events of zhibitai combined to atorvastatin in patients with coronary heart diseases (CHDs). Methods: Patients with CHD (n = 150) were randomized to: zhibitai 480 mg + atorvastatin 10 mg (ZA10 group), atorvastatin 20 mg (A20 group), and atorvastatin 40 mg (A40 group). Lipid profile, cardiotrophin-1 (CT-1), and C-reactive protein (CRP) were measured after 4 and 8 weeks of treatment. Self-reported side effects, liver function, kidney function, and creatine kinase levels were monitored. Results: After 8 weeks, triglycerides, total cholesterol (TC), LDL-cholesterol (LDL-C), and apolipoprotein B100 (ApoB100) levels were decreased in the ZA10 group (−64%, −37%, −46%, and −54%, respectively, compared with baseline), and these changes were similar to those of the A40 group (P > 0.05). CT-1 and high sensitivity-C reactive protein (hs-CRP) levels were significantly decreased in the ZA10 group after 4 and 8 weeks (4 weeks: −73% and 96%; 8 weeks: −89% and −98%; all P  0.05). After 8 weeks of treatment, adverse events (abdominal distention, nausea, vomiting, and hunger) were found in 4, 5, and 7 patients in the ZA10, A20, and A40 groups, respectively. Conclusion: ZA10 significantly reduced triglycerides, TC, LDL-C, ApoB, CT-1, and hs-CRP levels in patients with CHD, similar to the effects of A40 and A20, but ZA10 lead to fewer adverse events.

    Full Text Available Food stuffs with high flavonoids content  are believed to prevent various diseases caused by oxidative stress because of its antioxidants effect.  Purple sweet potato leaves have been proved containing high flavonoids, and can be developed very easily. To prove antioxidant and hypolipidemic properties of the water extract of purple sweet potato leaves, one research was conducted in the Department of Pharmacology, Faculty of Medicine, Udayana University. The study design was randomized control group pre- and post-test.  Twenty adult male wistar rats were divided into two groups of 10 rats. Both groups of rats were given high-cholesterol diet for three months to induce dyslipidemia. Control group of 10 rats were given only high-cholesterol diet alone, whereas the treatment group also treated with purple sweet potato leaf water extract with a dose of 6 cc per day divided into two doses. Before treatment and after treatment, lipid profile and blood SOD levels were measured. The results showed a decrease in total cholesterol, triglycerides and LDL cholesterol significantly in the treated group (P = 0.0001. In the treatment group there was also an increase in HDL cholesterol and blood SOD which was significantly differ than the control group (P = 0.0001. From the results of this study, it can be concluded that administration of water extract of purple sweet potato leaves can improve the lipid profile and increase blood SOD of rat given high-cholesterol diet.

    Full Text Available Introduction & Objective: Alpha amylase is the most important decomposing enzyme in starch. Digestion and absorption of starch in the intestine can be prevented and also the blood sugar levels can be controlled by restrain and control of alpha amylase. The aim of this study was to evaluate the effect of trans-chalcone on amylase activity, blood glucose and lipid levels in diabetic and non diabetic rats. Materials & Methods: This experimental study was conducted in 1388 at Tehran University of Medical Sciences. Sixty rats were randomly divided to ten equal groups: non diabetic control, diabetic control, four non diabetic experiments and four diabetic experiments. Control groups received grape seed oil and experimental groups received 2, 8,16 and 32 mg/kg of body weight in a period of 24 days with a gastric cannula. Blood sugar, every two days, serum insulin levels in days 0,12, and 24 and at the end of the experiment, lipoproteins and alpha amylase activity were measured.The data were analyzed by one way analysis of variance, ANOVA, followed by Turkey,s test with SPSS soft ware . Results: On average Chalcone reduced 25.5% of blood sugar in normal and diabetic rats. IT also decreased the serum insulin level. On average, chalcone decreased 34.9% of alpha amylase activity in normal and diabetic rats. Following disturbances in lipids metabolism caused by diabetes, this drug improved lipoproteins metabolism and reduced water, food and urine volume. Conclusion: This study shows that trans-Chalcone reduces blood sugar and body weight via inhibition of alpha amylas. Moreover, improvement of lipoprotein metabolism may happen via the inhibitory effect of this drug on hydroxyl methyl glutaryl -COA reductase and phosphodiesterase.

    Full Text Available Effective R&D and strict quality control of a broad range of foods, beverages, and pharmaceutical products require objective taste evaluation. Advanced taste sensors using artificial-lipid membranes have been developed based on concepts of global selectivity and high correlation with human sensory score. These sensors respond similarly to similar basic tastes, which they quantify with high correlations to sensory score. Using these unique properties, these sensors can quantify the basic tastes of saltiness, sourness, bitterness, umami, astringency and richness without multivariate analysis or artificial neural networks. This review describes all aspects of these taste sensors based on artificial lipid, ranging from the response principle and optimal design methods to applications in the food, beverage, and pharmaceutical markets.

Lead in fetus body is mainly derived from its mother's; therefore, blood lead reflects the level of mother's lead.OBJECTIVE: To analyze the correlations among blood lead level, trace elements, mental development index (MDI) and psychomotor development index (PDI) of 3-month-old children. DESIGN: Contrast observation. SETTING: Maternity and Child Care Hospital, Shanxi Provincial Children Hospital. PARTICIPANTS: A total of 128 neonates with spontaneous delivery were provided by Shanxi Maternity and Child Care Hospital and Jiexiu Municipal Maternity and Child Care Hospital from September 2004 to January 2005. There were 76 boys and 52 girls. All subjects did not have history of ischemia and hypoxia during perinatal period and umbilical blood was accepted to be used in experiments. METHODS: ① Levels of iron, calcium and zinc in umbilical blood: 0.5 mL umbilical blood and 2 mL blood samples were selected from neonates to measure lead content with graphite-oven atom absorption spectrum and contents of iron, calcium and zinc in umbilical blood with atom absorption spectrum. ② Grouping: According to level of blood lead, neonates were divided into high-dosage lead group (blood lead ≥ 0.24 μmol/L) and low-dosage lead group (blood lead < 0.24 μmol/L). ③ Evaluation of neurobehavioral development: Neurobehavioral development of 3-month-old neonates was evaluated with Bayley scale, which was consisted of intelligence scale, motor scale and behavioral scale. Intelligence scale, which was expressed as intelligence development index, contained 163 items, such as adaptability, behavior, language, pilot activities, etc. Motor scale, which was expressed as mental motor development index, contained 81 items, such as vulgar

Material and Methods: The concentration of malondialdehyde (MDA as the end-product of the lipid peroxidation (LPO was estimated in blood, liver, kidneys, and brain of Wistar rats, both healthy and those with complete Freund’s adjuvant (CFA-induced persistent paw inflammation. Results: The slightly elevated levels of the MDA in blood, kidney, and brain were observed among healthy rats in electromagnetic field (EMF-exposed groups, treated with tramadol (TRAM/EMF and exposed to the EMF. The malondialdehyde remained at the same level in the liver in all investigated groups: the control group (CON, the exposed group (EMF, treated with tramadol (TRAM as well as exposed to and treated with tramadol (TRAM/EMF. In the group of animals treated with the complete Freund’s adjuvant (CFA we also observed slightly increased values of the MDA in the case of the control group (CON and the exposed groups (EMF and TRAM/EMF. The MDA values concerning kidneys remained at the same levels in the control, exposed, and not-exposed group treated with tramadol. Results for healthy rats and animals with inflammation did not differ significantly. Conclusions: The electromagnetic field exposure (EMF, applied in the repeated manner together with opioid drug tramadol (TRAM, slightly enhanced lipid peroxidation level in brain, blood, and kidneys.

    This study was aimed to explore the correlation of hemogram changes during pregnancy of healthy women with postpartum blood transfusion. The outpatient and inpatient information of expectant lying-in women in our hospitals was collected, the route blood test, lever and kidney function and blood coagulation function tests were performed from the 4th to the 10th month of pregnancy. The pregnant women without underlying diseases and non-elderly pregnant women with single fetus were selected as the subjects of study. They were divided into postpartum blood transfusion group and non-blood transfusion group. The white blood cell (WBC) count, hemoglobin (Hb) level, platelet (Plt) count, plateletocrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW) were compared in 2 groups. The results showed that 68 cases out of 450 expectant lying-in women received blood transfusion, among them 30 cases with complete data of puerperal transfusion were taken as blood transfusion group, the 28 cases of non transfusion puerperal as control group. There was no significant difference of hemogram changes between the two groups. However, there was a slight decline in Plt count and Hb level of late pregnant women. What is more, there was no correlation between Plt count change and the PCT, MPV and PDW. It is concluded that the changes of hemogram during pregnancy has no correlation with postpartum hemorrhage and blood transfusion in healthy pregnant women, the Plt count and Hb level of pregnant women slightly decline. Nevertheless, PCT, MPV and PDW are within the normal range.

    Full Text Available OBJECTIVES: We used hearing tests and peripheral blood sample analyses to characterize the pathology of idiopathic sudden sensorineural hearing loss (ISSNHL and to identify possible prognostic factors for predicting recovery of hearing loss. STUDY DESIGN: A retrospective, multicenter trial was conducted. METHODS: Two hundred three patients examined within 7 days after the onset of ISSNHL received prednisone with lipo-prostaglandin E1. Pure-tone auditory tests were performed before and after treatment with these drugs. Blood tests were performed on blood samples collected during the patients' initial visit to our clinic. RESULTS: In all patients, elevated white blood cell (WBC counts, fasting blood sugar levels, HgbA1c, and erythrocyte sedimentation rate (ESR significantly correlated with high hearing threshold measurements obtained on the initial visit. High fibrinogen levels, WBC counts, ESR, and low concentrations of fibrinogen degradation products (FDP were associated with lower hearing recovery rates. Additionally, different audiogram shapes correlated with different blood test factors, indicating that different pathologies were involved. CONCLUSIONS: High fibrinogen levels measured within seven days after ISSNHL onset correlated with poorer hearing recovery. This may be a consequence of ischemia or infections in the inner ear. The high WBC counts also observed may therefore reflect an immune response to inner ear damage induced by ischemic changes or infections. Our data indicate that therapeutic strategies should be selected based on the timing of initial treatment relative to ISSNHL onset.

    1. When nineteen "free-living" male students, who normally ate 231 (SEM 14) g white bread/d changed to wholemeal bread for a 19-week period, there was no significant change in body-weight, plasma cholesterol or plasma triglyceride levels. These values, as well as plasma concentrations of calcium, phosphate, urate and haemoglobin, remained essentially the same as those for a control group. 2. Increasing the wheat-fibre intake by eating wholemeal bread is not an effective method for reducing blood lipids levels, at least in healthy young men with a moderate bread intake.

    Background: Control of blood sugar, hypertension, and dyslipidemia are key factors in diabetes management. Cucurbita ficifolia (pumpkin) is a vegetable which has been used traditionally as a remedy for diabetes in Iran. In addition, consumption of probiotics may have beneficial effects on people with Type 2 diabetes. The aim of this study was an investigation of the effects of C. ficifolia and probiotic yogurt consumption alone or at the same time on blood glucose and serum lipids in diabetic patients. Methods: Eighty eligible participants randomly were assigned to four groups: 1 - green C. ficifolia (100 g); 2 - probiotic yogurt (150 g); 3 - C. ficifolia plus probiotic yogurt (100 g C. ficifolia plus 150 g yogurt); and 4 -control (dietary advice) for 8 weeks. Blood pressure, glycemic response, lipid profile, and high-sensitive C-reactive protein (hsCRP) were measured before and after the intervention. Results: Total cholesterol (TC) decreased significantly in yogurt and yogurt plus C. ficifolia groups (within groups P = 0.010, and P < 0.001, respectively). C. ficifolia plus yogurt consumption resulted in a decrease in triglyceride (TG) and an increase in high-density lipoprotein cholesterol (HDL-C) (within groups P < 0.001 and P = 0.001, respectively). All interventions led to a significant decrease in blood sugar, hemoglobin A1c (HbA1c), hsCRP, and low-density lipoprotein cholesterol (LDL-C) level within groups. Blood pressure decreased significantly in Cucurbita group and yogurt group (within groups P < 0.001, and P = 0.001 for systolic blood pressure [SBP] and P < 0.001, and P = 0.004 for diastolic blood pressure [DBP], respectively). All variables changed between groups significantly except LDL-C level. Conclusions: Variables including TG, HDL-C, TC, fasting blood sugar, HbA1c, SBP, DBP, and hsCRP changed beneficially between groups. It seems that consumption of C. ficifolia and probiotic yogurt may help treatment of diabetic patients. PMID:26955460

    The blood flow in the human cardiovascular system obeys the laws of fluid mechanics. Investigation of the flow properties reveals that a correlation exists between the velocity in time and space. The possible changes in velocity are limited, since the blood velocity has a continuous profile in time...... of the observations gives a probability measure of the correlation between the velocities. Both the MLE and the STC-MLE have been evaluated on simulated and in-vivo RF-data obtained from the carotid artery. Using the MLE 4.1% of the estimates deviate significantly from the true velocities, when the performance...

    Full Text Available Introduction: Plasma ghrelin is influenced by nutritional status and is thought to play a role in acute and chronic regulating of food intake and body weight. The purpose of this study was to compare GH, insulin resistance index, lipid profile, and cardiorespiratory function in obese and lean inactive young men and determine their relationships with plasma acylated ghrelin levels. Methods: Study design of this research was causal-comparative. Obese (n=19, BMI: 31.0 kg/m2 and lean (n=19, BMI: 18.5 kg/m2 young men, without experience of regular physical activity during the previous six months, were selected. After 12 h fasting (at 8 a.m., blood samples were collected to determine blood parameter levels. Also, maximal oxygen uptake (as indicator of cardiorespiratory function of subjects was assessed. Results: Insulin levels and HOMA-IR (insulin resistance index were higher, and GH, acylated ghrelin and maximal oxygen uptake levels were lower in obese men compared to lean men (P0.01. Plasma acylated ghrelin concentrations were negatively correlated to body mass, body fat percent, body mass index, insulin and HOMA-IR, and positively correlated to GH levels and maximal oxygen uptake (P0.01.Conclusion: Obese and lean inactive young men had different levels of acylated ghrelin, GH, insulin, insulin resistance index, cardiorespiratory function and body fat percent. Body fat percent, insulin, and GH levels appear to be the strongest determinant factors of acylated ghrelin levels.

    Full Text Available BACKGROUND : Polycystic ovary syndrome is a condition associated with chronic anovulation, insulin resistance and androgen excess. Dyslipidemia, diabetes, obesity are all potent cardiovascular risk factors that tend to cluster in women with PCOD. These cannot be explained by obesity alone. Thus the need arises to study the effect of insulin resistance on these factors. This will help in assessing the long term cardiovascular morbidity in PCOD patients and take necessary preventive steps. OBJECTIVES : To analyze the infuence of obesity on lipid profile of PCOS women. To analyze the influence of insulin resistance on lipid profile in PCOS women. MATERIALS AND METHODS : In this prospective study done from December 2013 to September 2014, 50 women with PCOS had their body mass index and waist to hip ratio calculated. GTT, fasting and post prandial insulin, lipid profile was also done for each case. Insulin resistance was defined by fasting glucose to insulin ratio of less than or equal to 4.5. The association of obesity markers and insulin resistance with lipid markers was then studied. Statistical analysis using Student t test and ANOVA was done as indicated. Significance is assessed at 5% level of significance. RESULTS : Insulin resistance was seen in 56 percent of the cases. There was no correlation between markers of obesity (BMI and Waist to Hip ratio and the various lipid parameters. But in PCOS women with insulin resistance the lipid profile was significantly different (high triglycerides and lower high density lipoprotein compared to the insulin sensitive women. The difference between the two groups for triglycerides and HDL was statistically significant but that for LDL and total cholesterol was not statistically significant. CONCLUSION : Insulin resistance is associated with dyslipidemia in women with PCOS, independent of obesity.

    Full Text Available OBJECTIVES : 1 To study lipid profile in patients with type2 diabetes mellitus. 2 To study BMI in patients with type - 2 diabetes mellitus. 3 To correlate BMI and lipid profile in type - 2 diabetes mellitus subjects. Design: A hospital based study was done for 1 year. SETTING: ESIC MEDICAL COLLEGE & POST GRADUATE INSTITUTE OF MEDICAL SCIENCE & RESEARCH RAJAJINAGAR , BENGALURU. METHODS : Fasting lipid profile was studied in 100 patients of Type - 2 diabetes mellitus and none of them were on hypolipidemic drugs. Different fractions of lipid profile were compared between male and female , duration of diabetes and glycemic control. RESULTS : Out of 100 cases , 41 were males and 59 females. Most of in dividuals were obese. Most individuals had poor glycemic control (67%. Prevalence of hypercholesterolemia , hypertriglyceridemia , raised LDL - C was 62% , 63% , 76% respectively with no significant difference between male and female patients. Prevalence of low HDL - C was 94% , more in females than males with statistically significant difference. There was no correlation between dyslipidemia and glycemic control (HbA1c. As duration of diabetes increased there was increase in serum TG. Other parameters like TC , LD L - C , and HDL - C were not affected by duration of diabetes. Though statistically not significant , compared to males , females were more obese (BMI 24.72±3.82 vs. 26.33±4.62. CONCLUSION: Most of our patients had dyslipidemia irrespective of duration of diabete s. Female patientshad high frequency of low HDL which is an important risk factor for Coronary Heart Disease especially in type - 2 diabetic patients. It is therefore recommended that every type - 2 diabetic patients should have a fasting lipid profile measure d especially the female to reduce risk of CHD

    Full Text Available Background and objectives. Red blood cells (RBC are continuously exposed to oxidative agents, affecting their membrane lipid function. However, the amount of lipid in RBCs is higher than the lipids of the cell membrane, and includes triacylglycerols, which are no membrane components. We assumed that the extra lipids originated from lipoproteins attached to the cell surface, and we intended to analyse whether the size and composition of this lipid pool were affected by sex or diet.Experimental design. Adult male and female Wistar rats were fed control or cafeteria diets. Packed blood cells and plasma lipids were extracted and analysed for fatty acids by methylation and GC-MS, taking care of not extracting membrane lipids.Results. The absence of ω3-PUFA in RBC extracts (but not in plasma suggest that the lipids extracted were essentially those in the postulated lipid surface pool and not those in cell membrane. In cells’ extracts, there was a marked depletion of PUFA (and, in general, of insaturation. Fatty acid patterns were similar for all groups studied, with limited effects of sex and no effects of diet in RBC (but not in plasma fatty acids. Presence of trans fatty acids was small but higher in RBC lipids, and could not be justified by dietary sources.Conclusions. The presence of a small layer of lipid on the RBC surface may limit oxidative damage to the cell outer structures, and help explain its role in the transport of lipophilic compounds. However, there may be other, so far uncovered, additional functions for this lipid pool.

    Full Text Available Background: Iron deficiency anaemia is the most common nutritional anaemia among children. Lead toxicity is a serious health threat, especially in developing countries due to environmental pollution. It was thus aimed to investigate correlation between blood lead concentration and iron deficiency in children of Mashhad, Iran. Materials and Methods: This cross sectional study was performed on children between 1 year and 10 years, in Imam Reza teaching hospital of Mashhad, Iran, in 2010. Indeed during complete blood count (CBC, we measured iron and total iron binding capacity (TIBC by colorimetric methods, ferritin by radioimmune assay and blood lead concentration by atomic absorption method. Results were analysed by Statistical Package for Social Sciences (SPSS (version 11.5, using statistical tests including independent sample t-test, Mann-Whitney U test, Spearman′s test and analysis of variance (ANOVA and Pearson′s or Spearman′s correlation coefficient. P value ≤ 0.05 was considered as a significant level. Results: We studied 223 cases including 98 control children and 125 patients. All children had lead intoxication. Mean (±SD blood lead concentration in the control group was 57.1 ± 25.3 (ranged 20-212 μg/dl and in the patient group was 57 ± 20.4 (ranged 10.9-159 μg/dl with no significant difference (P value = 0.713. We also did not find any correlation between blood lead concentration and haemoglobin, ferritin, iron, TIBC, mean corpuscular volume (MCV, mean corpuscular haemoglobin (MCH, mean corpuscular haemoglobin concentration (MCHC, white blood cells (WBC and platelets. Conclusion: Based on these results, no correlation was found between blood lead concentration and iron deficiency in the children. Because all children had lead intoxication, further studies in highly polluted and a comparison with a low polluted area are necessary to make a general conclusion.

    Full Text Available Abstract Background We aimed to investigate if overweight and obese adults "close" to Mediterranean diet present better insulin, lipids profile and better pressure levels, compared to individuals close to a more Westernized diet. Methods The ATTICA study is a population-based cohort that has randomly enrolled 3042 adult men and women, stratified by age – gender, from the greater area of Athens, during 2001–2002. Of them, in this work were have studied 1762 participants with excess body weight, meaning overweight (BMI: 25–29.9 kg/m2 and obese (BMI>30 kg/m2. 1064 were men and 698 women (20–89 years old. Adherence to Mediterranean diet was assessed through a diet-score that was based on a validated food-frequency questionnaire. Blood pressure was measured and also fasting glucose, insulin and blood lipids. Insulin sensitivity was also assessed by the homeostasis model assessment (HOMA approach (glucose × insulin/22.5. Results Individuals with excess bodyweight in the highest tertile of diet score, were more insulin sensitive than those in the lowest tertile (11.4% lower HOMA, p = 0.06, had 13% lower levels of total cholesterol (p = 0.001 and 3 mmHg decrease of systolic blood pressure levels (p Conclusion Adherence to Mediterranean diet is modeslty associated with a better insulin sensitivity, lower levels of total cholesterol and lower levels of systolic blood pressure in overweight and obese subjects. This may suggest that compared to general population, the beneficial effect of this diet in cardiovascular system of excess body weight people is limited.

    Full Text Available Hyperlipidemia is one of the major risk factors of atherosclerosis and other cardiovascular diseases. This study aimed to investigate the impact of leucine rich pentatricopeptide repeat containing protein (LRPPRC-driven hepatic oxidative phoshorylation on blood lipid levels. The hepatic LRPPRC level was modulated by liver-specific transgenic or adeno-associated virus 8 carried shRNA targeting Lrpprc (aav-shLrpprc. Mice were fed with a high fat diet to induce obesity. Gene expression was analyzed by quantitative real-time PCR and / or western blot. The hepatic ATP level, hepatic and serum lipids contents, and mitochondria oxidative phosphorylation complex activities were measured using specific assay kits. The uptake and oxidation of fatty acid by hepatocytes were assessed using 14C-palmitate. LRPPRC regulated the expression of genes encoded by mitochondrial genome but not those by nuclear genome involved in mitochondria biogenesis, oxidative phosphorylation, and lipid metabolism. Increased oxidative phosphorylation in liver mediated by LRPPRC resulted in the increase of hepatic ATP level. Lrpprc promoted palmitate uptake and oxidation by hypatocytes. The hepatic and serum triglyceride and total cholesterol levels were inversely associated with the hepatic LRPPRC level. These data demonstrated that LRPPRC-driven hepatic oxidative phosphorylation could promote fatty acids uptake and oxidation by hepatocytes and reduce both hepatic and circulating triglyceride and cholesterol levels.

  4. Habitual Coffee Consumption Does Not Correlate with Blood Pressure, Inflammation and Endothelial Dysfunction but Partially Correlates with Oxidative Stress

    Full Text Available BACKGROUND: Coffee is the most widely consumed beverage in the world and has been known to have effects on cardiovascular system. Many researchers have examined the effects of coffee consumption on blood pressure (BP and risk of cardiovascular disease (CVD, but their results were inconsistent and still remain a subject of controversy. Oxidative stress, inflammation, and endothelial dysfunction have been known as risk factors of hypertension and CVD. Those factors are also known to be affected by coffee consumption. The aim of this study was to examine the relationship between the effects of habitual coffee consumption on BP and to examine the role of oxidative stress (F2 isoprostane, inflammation (high sensitive C-reactive protein (hsCRP and endothelial dysfunction (asymmetric dimethylarginine (ADMA. METHODS: This was a cross-sectional study in which 47 healthy, non-smoking men aged 30-60 years with varying coffee-drinking habits were enrolled. BP and blood/urine analysis of biomarkers were measured in the morning before activity. Coffee consumption was assessed using a questionnaire. The differences among variables were analyzed using ANOVA and the correlations between variables were analyzed using Kendall’s Tau correlation analysis. RESULTS: Habitual coffee consumption did not correlate with systolic/diastolic BP (r=-0.02; p=0.856 and r=0.15; p=0.230, respectively. Concentrations of ADMA and hsCRP were also not correlated with coffee consumption (r=0.03; p=0.764 and r=0.04; p=0.701, respectively. Coffee consumption only showed significant correlation with F2 isoprostane (r=0.34; p=0.004. CONCLUSIONS: BP was not affected by coffee consumption although coffee consumption has a significant correlation with F2 isoprostane. These findings suggest that correlation between coffee consumption and BP might be explained by other factors that were not included in this study.

    1980-11-01

    Twenty-four volunteers, mean age 78, including eight mildly non-insulin-dependent diabetics, were randomly allocated to one of two groups and were fed (daily for 8 wk) 9 g of either chromium-rich brewers' yeast (experimental) or chromium-poor torula yeast (control). Before and after yeast supplementation, the serum glucose and insulin response to 100 g oral glucose was measured at 30 min intervals for 2 h. Fasting serum cholesterol, total lipids, and triglycerides were also determined. In the total experimental group (normals + diabetics) and in both the diabetic and nondiabetic experimental subgroups, glucose tolerance improved significantly and insulin output decreased after supplementation. Cholesterol and total lipids fell significantly after supplementation in the total experimental group. The cholesterol decrease was particularly marked in hypercholesterolemic subjects (cholesterol > 300 mg/dl). In the control group, no significant change in glucose tolerance, insulin, triglycerides, or total lipids was found. Cholesterol was significantly lowered in the nondiabetic but not in the diabetic group. Thus, chromium-rich brewers' yeast improved glucose tolerance and total lipids in elderly subjects, while chromium-poor torula yeast did not. An improvement in insulin sensitivity also occurred with brewers' yeast supplementation. This supports the thesis that elderly people may have a low level of chromium and that an effective source for chromium repletion, such as brewers' yeast, may improve their carbohydrate tolerance and total lipids. The improvement in serum cholesterol in some control subjects, as well as in the total experimental group, also suggests the presence of a hypocholesterolemic factor other than chromium in both brewers' and torula yeast.

    题目:太极锻炼对血脂的临床疗效:随机对照试验的meta分析目的:探讨太极锻炼是否能改善血脂水平。创新点:明确太极锻炼对血脂的影响,为非药物调脂治疗提供新手段。方法:通过筛选太极锻炼持续4周以上,PEDro评分3分以上,且观察太极锻炼对血脂影响的成人随机对照试验,meta分析太极锻炼对总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇和甘油三酯的影响。结论:通过meta分析最终入选的6项研究(共445例患者)的结果显示,太极锻炼能显著降低血甘油三酯水平,且有降低总胆固醇的趋势,但是对于低密度脂蛋白胆固醇和高密度脂蛋白胆固醇未发现有明显影响。%Objective: Studies have demonstrated that Tai Chi exercise improves blood lipid level with inconsistent results. A meta-analysis was conducted to quantify the effects of Tai Chi on blood lipid profiles in humans. Methods: We screened the databases of PubMed, EMBASE, Cochrane Library (Central), Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang data, and Clinicaltrials.gov for randomized controlled trials with Physio-therapy Evidence Database (PEDro) score more than 3 points up to June 2015. Six studies involving 445 subjects were included. Most trials applied 12-week Tai Chi intervention courses. Results: In comparison with the control group, blood triglyceride (TG) level difference between folow-up and baseline was statisticaly significantly lower in the Tai Chi practicing group (weighted mean difference (WMD)−16.81 mg/dl; 95% confidence intervals (CI)−31.27 to−2.35 mg/dl;P=0.02). A trend to improving total cholesterol (TC) reduction was found with Tai Chi (WMD−7.96 mg/dl; 95% CI−17.30 to 1.39 mg/dl;P=0.10). However, no difference was found in blood low-density lipoprotein cholesterol (LDL-C) or high-density lipoprotein cholesterol (HDL-C). Conclusions: Tai Chi exercise lowered

    Full Text Available Background: Studies have suggested that an elevated plasma concentration of apolipoprotein (apo B coupled with obesity may be considered as an important risk factor for coronary heart disease (CHD than the traditional lipid factors. Coronary artery disease (CAD is a multifactorial disease resulting from interaction among various hereditary, cultural and environment factors. Population specific studies are rare. Aim: The aim of this study was to evaluate the association of body mass index (BMI, blood lipids and apolipoproteins with the CAD among the Khatri caste, which is an indigenous population of Northwest India. Materials and Methods: The study was carried on 150 CAD patients and 150 normal controls belonging to the Punjabi Khatri caste ranging in age from 35-45 years. Height and body weight was measured using standard techniques. Blood was drawn from each subject to analyze serum concentrations of lipids and apolipoproteins. Results: The study demonstrated that CAD patients had elevated BMI in both males and females than normal controls. Apo B levels were an important predictor of CAD. ApoA/ApoB ratio among CAD patients was 0.74 compared with 1.53 in normal subjects; controls had 105.79% higher ApoA/ApoB ratio than CAD subjects. Total cholesterol, LDL-C, triglycerides, LDL-C/HDL-C ratio of the two groups also showed significant differences. Prevalence of obesity in CAD patients was 70.7% compared with 10% in normal controls. Conclusions: Apo B levels were found to the best predictor of CAD, even though significant differences were also found between CAD and normal subjects for other lipoprotein traits. Obesity was high CAD patients than normal controls.

    Full Text Available Context: Acne vulgaris (AV is a common disease affecting all ages and ethnic groups. Androgens, skin and serum lipids, inflammatory signaling and regulatory neuropeptides seem to be involved in this multi-factorial process. Aim: The aim of this work was to determine hormonal levels and lipid profile in non-obese, non-hirsute females with AV. Subjects and Methods: A total of 60 non-obese, non-hirsute female cases with different grades of AV and 60 age- and gender-matched healthy volunteers were included. Measurement of serum total and free testosterone, sex hormone binding globulin (SHBG, estradiol and progesterone and blood lipids was done during the luteal phase of the menstrual cycle. Results: Total testosterone, free testosterone (FT and progesterone levels were significantly higher (P < 0.001 for all while estradiol levels (P < 0.001 and SHBG (P < 0.01 were significantly lower in cases than controls. Total cholesterol and low density lipoprotein cholesterol (LDL-C levels were significantly higher (P < 0.001 for both while high density lipoprotein cholesterol (HDL-C and apolipoprotein A-1 (ApoA-1 levels were significantly lower (P < 0.001 for both in cases than controls. Higher values of FT (P = 0.03 and SHBG (P = 0.02 and lower values of estradiol (P = 0.04 levels were significantly in favor of severe acne. Higher values of cholesterol (P < 0.001 and LDL-C (P = 0.03 and lower values of HDL-C (P = 0.01 and ApoA-1 (P = 0.02 levels were significantly associated with severe acne. Conclusion: Changes in hormone levels and lipid profile in non-obese and non-hirsute females with AV should be considered in disease pathogenesis and in treatment prescription of these patients.

    The main objective of this study was to investigate the prevalence of hypertension, glucose and blood lipid abnormalities among a community of Ethiopian immigrants in Minnesota. This cross-sectional study used data from the parish nursing program 2007-2012. A total of 673 encounters were included in this study. Various dependent variables including systolic blood pressure (SBP), diastolic blood pressure (DBP), blood glucose (BG), and serum lipids were examined. High blood pressure was defined as a mean SBP equal to or higher than 140 mm/Hg and/or DBP equal to or higher than 90 mmHg. Elevated fasting glucose defined as levels equal to or higher than 126 mg/dL. High level of total cholesterol (TC), total triglyceride (TG), low-density lipoprotein (LDL) cholesterol, and low high-density lipoprotein (HDL) cholesterol were defined as ≥240, ≥200, ≥160 and ≤40 mg/dL, respectively. General linear regression models were used to investigate the relationship of participants' age and gender, to the continuously distributed response variables, which included systolic and DBP, BG, TC, TG, LDL cholesterol and HDL cholesterol. This is a nonrandom sample of adult Ethiopian church members who were invited to participate in a parish nurse cardiovascular disease (CVD) risk factor screening program. Participants in this sample were 43 % male and 57 % female. The overall prevalence of hypertension was 30.1 % with a cut off mark of 140/90 mm/Hg. The prevalence of hypertension was 33 and 24 % among men than among women, respectively (p 240 mg/dL) were observed in 15 % of the women and 10 % of the men (p = 0.2). Higher SBP and DBP were significantly higher in male participants than their female counterparts (p  0.05). This opportunity sample suggests high prevalence of CVD risk factors in a community of Ethiopian-American adults, and a pressing need for more comprehensive and systematic assessment of chronic disease health needs in this growing community.

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

    Full Text Available Gender differences in lipid metabolism are poorly understood and difficult to study using conventional approaches. Magnetic resonance spectroscopy (MRS permits non-invasive investigation of lipid metabolism. We employed novel two- dimensional MRS techniques to quantify intramyocellular (IMCL and extramyocellular (EMCL lipid compartments and their degree of unsaturation in normal weight adult male and female subjects. Using muscle creatine (Cr for normalization, a statistically significant (p 0.05 increase in IMCL/Cr (7.8 ± 1.6 and EMCL/Cr (22.5 ± 3.6 for female subjects was observed (n = 8, as compared to IMCL/Cr (5.9 ± 1.7 and EMCL/Cr (18.4 ± 2.64 for male subjects. The degree of unsaturation within IMCL and EMCL was lower in female subjects, 1.3 ± 0.075 and 1.04 ± 0.06, respectively, as compared to that observed in males (n = 8, 1.5 ± 0.08 and 1.12 ± 0.03, respectively (p 0.05 male vs female for both comparisons. We conclude that certain salient gender differences in lipid metabolism can be assessed noninvasively by advanced MRS approaches.

    To study the usefulness of traditional lipid profile levels in screening subjects who had developed chest pain due to cardiac event as indicated by a positive troponin I test. Methods: In this retrospective study data of the 430 patients presented to the emergency department with symptoms of cardiac ischemia who underwent both troponin and lipid profiles tests were compared with the lipid profiles of 165 normal healthy subjects (controls). The troponin was detected qualitatively when a specimen contains troponin I (cTnI) above the 99th percentile (TnI>0.5 ng/mL). The total cholesterol, high density lipoproteins cholesterol, very low density lipoproteins and triacyl glycerol levels were also analyzed and low density lipoprotein level was calculated using Friedewald’s formula. Results: Patients with chest pain and positive troponin test (with confirmed cardiac event) were found to have significantly elevated levels of total cholesterol, triacyl glycerol levels, low density lipoprotein level and significantly reduced high density lipoproteins cholesterol levels when compared to the patients who experienced only chest pain (negative troponin) and healthy controls. Conclusions: Traditional lipid profile levels is still can be used in screening populations to identify the subjects with high risk of developing cardiac event in case if the laboratory set up has not troponin test facilities.

    Full Text Available Purpose. This study aimed to explore the relationship among insulin sensitivity and ectopic fat depots in participants with different glucose status. Methods. Fifty-nine men and women were enrolled in this study: 29 with normal glucose tolerance (NGT, 17 with impaired glucose tolerance (IGT, and 13 with type 2 diabetes mellitus (T2DM. All participants underwent a hyperinsulinemic-euglycemic clamp to assess the insulin sensitivity index (M value and magnetic resonance imaging to measure the hepatocellular lipid content (HCL, skeletal muscle fat content including intramyocellular lipid (IMCL and extramyocellular lipid (EMCL of tibialis anterior (ta, and soleus muscle (sol. Results. The M value of NGT group was higher than those of IGT and T2DM groups (P=0.001. Participants with T2DM had the highest HCL and IMCL (ta compared with those in NGT and IGT groups (P=0.001. The M value had an inverse relationship with HCL (r=-0.789, P=0.001, IMCL (sol (r=-0.427, P=0.002, and IMCL (ta (r=-0.419, P=0.002. Stepwise linear regression analysis showed that HCL (standardized β=-0.416; P=0.001 had an independent relationship with M value. Conclusions. Hepatocellular lipid content deposition happens earlier than skeletal muscle fat deposition. HCL is an independent risk factor for insulin resistance and may be used to evaluate the risk of developing T2DM as a noninvasive marker of insulin sensitivity index.

    Bone marrow (BM) analysis is of forensic interest in postmortem toxicological investigation in case of limited, unavailable or unusable blood samples. However, it remains difficult to determine whether a drug BM concentration is therapeutic or represents overdose, due to the lack of studies on this alternative matrix. Given the variations in BM composition in the body, sample location was suggested to be a relevant factor in assessing BM concentration. The aim of the present study was to compare postmortem caffeine concentrations in various BM sample locations and secondly to consider the correlation between BM and blood concentrations. Six BM samples (right and left side: proximal and medial femur and 5th rib) and a blood sample were collected from 21 forensic autopsies. Gas chromatography coupled to tandem mass spectrometry was performed. Blood caffeine concentrations ranged from 60 to 7591ng/mL. Femoral and rib BM concentrations ranged from 51 to 6171ng/g and 66 to 7280ng/g, respectively. Blood concentrations were always higher than BM concentrations. As a good correlation was demonstrated between blood and rib BM and between blood and the average of the four femoral BM concentrations, blood caffeine concentrations could be correctly extrapolated from BM concentrations. BM caffeine concentration was found to depend on sample location. Rib BM caffeine concentrations appeared to be systematically greater than averaged femur values and concentrations were much more variable between the 4 femur BM samples than between the 2 ribs. From a practical point of view, for caffeine analysis, rib BM appeared more relevant than femoral BM, which requires multisampling to overcome the concentration variability problem.

    Full Text Available BACKGROUND: Elevated cholesterol levels in children can be a risk factor for cardiovascular diseases in later life. In adults, it has been shown that blood lipid levels are strongly influenced by polymorphisms in the fatty acid desaturase (FADS gene cluster in addition to nutritional and other exogenous and endogenous determinants. Our aim was to investigate whether lipid levels are determined by the FADS genotype already in children and whether this association interacts with dietary intake of n-3 fatty acids. METHODS: The analysis was based on data of 2006 children from two German prospective birth cohort studies. Total cholesterol, HDL, LDL and triglycerides were measured at 10 years of age. Six single nucleotide polymorphisms (SNPs of the FADS gene cluster were genotyped. Dietary n-3 fatty acid intake was assessed by food frequency questionnaire. Linear regression modeling was used to assess the association between lipid levels, n-3 fatty acid intake and FADS genotype. RESULTS: Individuals carrying the homozygous minor allele had lower levels of total cholesterol [means ratio (MR ranging from 0.96 (p = 0.0093 to 0.98 (p = 0.2949, depending on SNPs] and LDL [MR between 0.94 (p = 0.0179 and 0.97 (p = 0.2963] compared to homozygous major allele carriers. Carriers of the heterozygous allele showed lower HDL levels [β between -0.04 (p = 0.0074 to -0.01 (p = 0.3318] and higher triglyceride levels [MR ranging from 1.06 (p = 0.0065 to 1.07 (p = 0.0028] compared to homozygous major allele carriers. A higher n-3 PUFA intake was associated with higher concentrations of total cholesterol, LDL, HDL and lower triglyceride levels, but these associations did not interact with the FADS1 FADS2 genotype. CONCLUSION: Total cholesterol, HDL, LDL and triglyceride concentrations may be influenced by the FADS1 FADS2 genotype already in 10 year old children. Genetically determined blood lipid levels during childhood might

    Full Text Available Animal models that mimic human biology are important for successful translation of basic science discoveries into the clinical practice. Recent studies in rodents have demonstrated the efficacy of TLR4 agonists as immunomodulators in models of infection. However, rodent models have been criticized for not mimicking important characteristics of the human immune response to microbial products. The goal of this study was to compare genomic responses of human and sheep blood to the TLR4 agonists lipopolysaccharide (LPS and monophosphoryl lipid A (MPLA.Venous blood, withdrawn from six healthy human adult volunteers (~ 28 years old and six healthy adult female sheep (~3 years old, was mixed with 30 μL of PBS, LPS (1μg/mL or MPLA (10μg/mL and incubated at room temperature for 90 minutes on a rolling rocker. After incubation, 2.5 mL of blood was transferred to Paxgene Blood RNA tubes. Gene expression analysis was performed using an Agilent Bioanalyzer with the RNA6000 Nano Lab Chip. Agilent gene expression microarrays were scanned with a G2565 Microarray Scanner. Differentially expressed genes were identified.11,431 human and 4,992 sheep probes were detected above background. Among them 1,029 human and 175 sheep genes were differentially expressed at a stringency of 1.5-fold change (p 1.5-fold changes in human samples. Genes of major inflammatory mediators, such as IL-1, IL-6 and IL-8, TNF alpha, NF-kappaB, ETS2, PTGS2, PTX3, CXCL16, KYNU, and CLEC4E were similarly (>2-fold upregulated by LPS and MPLA in both species.The genomic responses of peripheral blood to LPS and MPLA in sheep are quite similar to those observed in humans, supporting the use of the ovine model for translational studies that mimic human inflammatory diseases and the study of TLR-based immunomodulators.

    Full Text Available Monounsaturated fatty acids (MUFA are emerging health biomarkers, and in particular the ratio between palmitoleic acid (9cis-16:1 and palmitic acid (16:0 affords the delta-9 desaturase index that is increased in obesity. Recently, other positional and geometrical MUFA isomers belonging to the hexadecenoic family (C16 MUFA were found in circulating lipids, such as sapienic acid (6cis-16:1, palmitelaidic acid (9trans-16:1 and 6trans-16:1. In this work we report: i the identification of sapienic acid as component of human erythrocyte membrane phospholipids with significant increase in morbidly obese patients (n = 50 compared with age-matched lean controls (n = 50; and ii the first comparison of erythrocyte membrane phospholipids (PL and plasma cholesteryl esters (CE in morbidly obese patients highlighting that some of their fatty acid levels have opposite trends: increases of both palmitic and sapienic acids with the decrease of linoleic acid (9cis,12cis-18:2, omega-6 in red blood cell (RBC membrane PL were reversed in plasma CE, whereas the increase of palmitoleic acid was similar in both lipid species. Consequentially, desaturase enzymatic indexes gave different results, depending on the lipid class used for the fatty acid content. The fatty acid profile of morbidly obese subjects also showed significant increases of stearic acid (C18:0 and C20 omega-6, as well as decreases of oleic acid (9cis-18:1 and docosahexaenoic acid (C22:6 omega-3 as compared with lean healthy controls. Trans monounsaturated and polyunsaturated fatty acids were also measured and found significantly increased in both lipid classes of morbidly obese subjects. These results highlight the C16 MUFA isomers as emerging metabolic marker provided that the assignment of the double bond position and geometry is correctly performed, thus identifying the corresponding lipidomic pathway. Since RBC membrane PL and plasma CE have different fatty acid trends, caution must also be used in

    The study was undertaken to investigate the effect of sesame oil in hypertensive patients who were on antihypertensive therapy either with diuretics (hydrochlorothiazide) or ß-blockers (atenolol). Thirty-two male and 18 female patients aged 35 to 60 years old were supplied sesame oil (Idhayam gingelly oil) and instructed to use it as the only edible oil for 45 days. Blood pressure, anthropometry, lipid profile, lipid peroxidation, and enzymic and non-enzymic antioxidants were measured at baseline and after 45 days of sesame oil substitution. Substitution of sesame oil brought down systolic and diastolic blood pressure to normal. The same patients were asked to withdraw sesame oil consumption for another 45 days, and the measurements were repeated at the end of withdrawal period. Withdrawal of sesame oil substitution brought back the initial blood pressure values. A significant reduction was noted in body weight and body mass index (BMI) upon sesame oil substitution. No significant alterations were observed in lipid profile except triglycerides. Plasma levels of sodium reduced while potassium elevated upon the substitution of sesame oil. Lipid peroxidation (thiobarbituric acid reactive substances [TBARS]) decreased while the activities of superoxide dismutase (SOD), catalase (CAT), and the levels of vitamin C, vitamin E, ß-carotene, and reduced glutathione (GSH) were increased. The results suggested that sesame oil as edible oil lowered blood pressure, decreased lipid peroxidation, and increased antioxidant status in hypertensive patients. PMID:17876372

    Full Text Available Serum lipids are associated with myocardial infarction and cardiovascular disease in humans. Here we dissected the genetic architecture of blood lipid traits by applying genome-wide association studies (GWAS in 1,256 pigs from Laiwu, Erhualian and Duroc × (Landrace × Yorkshire populations, and a meta-analysis of GWAS in more than 2,400 pigs from five diverse populations. A total of 22 genomic loci surpassing the suggestive significance level were detected on 11 pig chromosomes (SSC for six blood lipid traits. Meta-analysis of GWAS identified 5 novel loci associated with blood lipid traits. Comparison of GWAS loci across the tested populations revealed a substantial level of genetic heterogeneity for porcine blood lipid levels. We further evaluated the causality of nine polymorphisms nearby or within the APOB gene on SSC3 for serum LDL-C and TC levels. Of the 9 polymorphisms, an indel showed the most significant association with LDL-C and TC in Laiwu pigs. But the significant association was not identified in the White Duroc × Erhualian F2 resource population, in which the QTL for LDL-C and TC was also detected on SSC3. This indicates that population-specific signals may exist for the SSC3 QTL. Further investigations are warranted to validate this assumption.

    The effect of the bee toxin melittin on DMPC dynamics in fast-tumbling bicelles has been investigated. The (13)C R(1) and (13)C-(1)H NOE relaxation parameters for DMPC were used to monitor the effect of melittin and cholesterol on lipid dynamics. It was found that melittin has the largest effect on the DMPC mobility in DMPC/DHPC bicelles, while less effect was observed in cholesterol-doped bicelles, or in bicelles made with CHAPS, indicating that the rigidity of the membrane affects the melittin-membrane interaction. CD spectra were analysed in terms of cooperativity of the alpha-helix to random coil transition in melittin, and these results also indicated similar differences between the bicelles. The study shows that bicelles can be used to investigate lipid dynamics by spin relaxation, and in particular of peptide-induced changes in membrane fluidity.

    Full Text Available The present study examined the effects of progressive exercise (pyramidal short-term program on plasma fibrinogen, lipid profile and blood viscosity in untrained young men. Changes and imbalances in homeostasis lead to cause of heart attacks. There is conflicting information about the effect of exercise on these factors. 19 young healthy untrained men were randomly assigned to the exercise group (n = 10 and controls (n = 9 groups. Exercise training group with increasing severity of heart maximum 25 to 100 percent began to run the practice (pyramid in 42-minute sessions, 3 times a week, for 4 weeks. There was no significant difference between the parameters of body composition, control, and training groups. Levels of total cholesterol and low density lipoprotein density and viscosity of the blood significantly decreased in the training group compared with the control group (p value, respectively is 0.001, 0.001 and 0.035. The changes in the concentration of fibrinogen, high-density lipoprotein and triglycerides in both groups are not significant in both groups (p value, respectively is 0.645, 0.993 and 0.421. The present results show that it is possible that progressive training (pyramidal short-term program changed the levels of cardiovascular risk factors by reducing blood viscosity.

    ABSTRACT Introduction: Lead toxicity is a serious health threat, especially in developing countries due to environmental pollution. It was thus aimed to investigate correlation between blood lead level and concentration level of hemoglobin in the blood of children involved in research. Material and methods: The research included 250 children of which 31(12.4%) kindergarten children, 166 (66.4%) of primary school pupils in Mitrovica and 53(21.2%) of primary school pupils in Shtime as control group. From the 250 children included in the survey 129 or 51.6% were female children and 48.4% male children. Children were selected randomly, while tests for concentration of Pb and blood hemoglobin were done at the National Institute of Public Health. Results: The average value of blood lead level of Mitrovica pupils was 2.4 µg/dL (SD±1.9µg/dL), range 0.5 to 16.3µg/dL. The average value of blood lead level of Shtime pupils was 2.3µg/dL (SD±0.7µg/dL), range 1.2 to 5.2 µg/dL with no statistical difference (P = 0.191). The average value of blood lead level in kindergarten children of Mitrovica was 3.8µg/dL (SD±1.3µg/dL), range 2.2 to 7.7µg/dL with significant difference between the average values of blood lead levels of pupils and kindergarten children of Mitrovica (P <0.0001). The average value of hemoglobin in the pupils of Mitrovica was 14.0g/dL(SD± 3.7g/dL), range 9.4 to 25.6 g/dL. The average value of hemoglobin to pupils of Shtime was 11.4g/dl(SD±0.8 g/dl), range 9.2 to 13.0 g/dl with significant difference between mean values of hemoglobin pupils of Mitrovica and Shtime (U ‘= 6440.0, P <0.0001). With Spearman correlation is found significant correlation of a medium scale (r = -0.305, df = 248, p <0.0001) between blood lead levels and hemoglobin level in the blood. PMID:25568564

    BACKGROUND: Storage duration of red cells has been associated with increased morbidity and mortality following transfusion. This association has been attributed to the loss of deformability of stored red cells leading to deterioration of microvascular perfusion. ATP content is considered a critical determinant of the deformability of stored red cells. METHODS: ATP content and deformability were determined after storage for up to 49 days in 40 leukocyte-depleted whole blood units. Red cell deformability was determined using a laser-assisted optical rotational cell analyzer (LORCA( (®) )) employing shear stress (SS) ranging from 0.3 to 30 Pa. Deformability was expressed as the elongation index (EI). EI was correlated with ATP content. RESULTS: ATP content decreased from 3.5 to 1.7 ?mol/g hemoglobin. EI increased from 0.03 to 0.05 at an SS of 0.3 Pa, and decreased from 0.62 to 0.59 at an SS of 30 Pa. Correlation coefficient (r) of ATP vs. EI at 0.3 Pa ranged from -0.17 to +0.15 during storage. At 30 Pa, r ranged from -0.03 to +0.45. Correlation increased with storage irrespective of SS, and increased with SS irrespective of storage. CONCLUSIONS: ATP content is not a valid surrogate marker for red cell deformability and may not reflect in vivo survival of stored red cells.

    Growing research has demonstrated a link between spiritual well-being and better health; however, little is known about possible physiological mechanisms. In a sample of highly religious healthy male and female adults (n = 100) ages 19-59 (m = 28.28) we examined the influence of spiritual well-being, as measured by the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp-Ex), on physiological risk factors for heart disease. Specifically we examined 24-h ambulatory blood pressure (BP), inflammation (hs-C-reactive protein), fasting glucose, and blood lipids. Regression analyses reveal that higher levels of spiritual-wellness (total FACIT-Sp-Ex score) was significantly related to lower systolic ambulatory BP (β = -.345; P < .001), diastolic ambulatory BP (β = -.24; P = .02), hs-C-reactive protein (β = -.23; P = .04), fasting glucose (β = -.28; P = .006), and marginally lower triglycerides (β = -.21; P = .09) and VLDL (β = -.21; P = .10) controlling for age, gender, and church attendance. Results remained generally consistent across the Meaning, Peace, Faith and Additional Spiritual Concerns subscales of the FACIT-Sp-Ex. Spiritual well-being may be cardio protective.

    Protein fraction able to induce K(+)-selective transport across bilayer lipid membrane was isolated from human blood plasma with the use of the detergent and proteolytic enzyme-free method developed at our laboratory. After addition of the studied sample to the artificial membrane in the presence of 100 mM KCl, a discrete current change was observed. No channel activity was recorded in the presence of calcium and sodium ions. Channel forming activity of fraction was observed only in the presence of K+. Using a threefold gradient of KCl in the presence of studied proteins the potassium-selective potential balanced by voltage of -29 mV was registered. This value is very close to the theoretical Nernst potential in this case. This means that the examined ion channel is cation-selective. According to data obtained with MS-MALDI-TOF/TOF and database NCBI three protein components were identified in isolated researched sample.

    Lipid matrix particles (LMP) may be used as better carriers for poorly water-soluble drugs than liquid lipid carriers because of reduced drug mobilization in the formulations. However, the digestion process of solid lipid particles and their effect on the absorption of poorly water-soluble drugs are not fully understood. This study aimed at investigating the effect of particle size of LMP on drug release in vitro as well as absorption in vivo in order to get a better understanding on the effect of degradation of lipid particles on drug solubilisation and absorption. Fenofibrate, a model poorly water-soluble drug, was incorporated into LMP in this study using probe ultrasound sonication. The resultant LMP were characterised in terms of particle size, size distribution, zeta potential, entrapment efficiency, in vitro lipolysis and in vivo absorption in rat model. LMP of three different particle sizes i.e. approximately 100 nm, 400 nm, and 10 μm (microparticles) were produced with high entrapment efficiencies. The in vitro lipolysis study showed that the recovery of fenofibrate in the aqueous phase for 100 nm and 400 nm LMP was significantly higher (pdigested to a larger extent due to greater specific surface area. The 100 nm LMP showed faster initial digestion followed by 400 nm LMP and microparticles. The area under the plasma concentration-time curve (AUC) following oral administration of 100 nm LMP was significantly higher (pabsorption and the in vitro response was observed. The recovery (%) of fenofibrate partitioning into the aqueous phase during in vitro lipolysis and the AUC of plasma concentration-time curve of fenofibric acid was in the order of 100 nm LMP>microparticles>control. In summary, the present study demonstrated the particle size dependence of bioavailability of fenofibrate loaded LMP in rat model which correlates well with the in vitro drug release performed in the biorelevant medium.

    Lipid emulsions containing long-chain triglycerides (LCT) and medium chain triglycerides (MCT) are widely used in parenteral nutrition. Recently, fish oil (FO) triglyceride (TG)-derived emulsions are considered therapeutic because of their many beneficial biological modulatory actions. We investigated in mice whether adding 10% FO to an intravenous lipid emulsion with MCT and LCT (MCT:LCT:FO -50:40:10% by wt) would affect particle blood clearance and tissue targeting in comparison to LCT (100% by wt) and MCT:LCT (50:50% by wt) emulsions. The 3 emulsions were labeled with [3H] cholesteryl oleoyl ether and administered by bolus injection (400 microg TG/mouse) to C57BL/6J mice. Contributions of LDL receptor (LDL-R) and LDL-R-related protein to emulsion catabolism were assessed using LDL-R-deficient mice and preinjection of lactoferrin, and the effects of lipoprotein lipase (LPL) were determined by preinjection of heparin and Triton WR 1339. Although fractional catabolic rates did not differ among the 3 emulsions, blood removal at each time point after injection was greater for MCT:LCT:FO particles due to their higher initial margination volume. Compared with MCT:LCT and LCT emulsions, patterns of tissue uptake of the MCT:LCT:FO emulsions were different, e.g. MCT:LCT:FO emulsion particle uptake was lower in heart, adipose tissue, and muscle, and higher in lung, and the removal of MCT:LCT:FO emulsion particles was less dependent on LPL, LDL-R, and lactoferrin-sensitive pathways. These data suggest that the addition of a low percentage of FO to MCT:LCT emulsions substantially changes their particle clearance and tissue uptake mechanisms.

    In this study, we conducted a meta-analysis of self-controlled cohort studies comparing body weights, blood levels of lipids and fasting blood glucose levels before and after Ramadan taking into account gender differences. Several databases were searched up to June 2012 for studies showing an effect of Ramadan fasting in healthy subjects, yielding 30 articles. The primary finding of this meta-analysis was that after Ramadan fasting, low-density lipoprotein (SMD = -1.67, 95 % CI = -2.48 to -0.86) and fasting blood glucose levels (SMD = -1.10, 95 % CI = -1.62 to -0.58) were decreased in both sex groups and also in the entire group compared to levels prior to Ramadan. In addition, in the female subgroup, body weight (SMD = -0.04, 95 % CI = -0.20, 0.12), total cholesterol (SMD = 0.05, 95 % CI = -0.51 to 0.60), and triglyceride levels (SMD = 0.03, 95 % CI = -0.31, 0.36) remained unchanged, while HDL levels (SMD = 0.86, 95 % CI = 0.11 to 1.61, p = 0.03) were increased. In males, Ramadan fasting resulted in weight loss (SMD = -0.24, 95 % CI = -0.36, -0.12, p = 0.001). Also, a substantial reduction in total cholesterol (SMD = -0.44, 95 % CI = -0.77 to -0.11) and LDL levels (SMD = -2.22, 95 % CI = -3.47 to -0.96) and a small decrease in triglyceride levels (SMD = -0.35, 95 % CI = -0.67 to -0.02) were observed in males. In conclusion, by looking at this data, it is evident that Ramadan fasting can effectively change body weight and some biochemical parameters in healthy subjects especially in males compared to pre-Ramadan period.

    The burning issue in modern medicine is the diagnosis and treatment of various life-threatening diseases, in particular the diseases of brain. One of them is intracranial hemorrhage (ICH). It occurs especially among newborn babies and is hard-diagnosed. In order to understand the nature of the ICH, the microcirculation of blood, which serves key functions within the body, is analyzed. On this basis a series of experiments was done, in the results of which it was showed, that latent stage of ICH is characterized by decrease of venous blood outflow and the loss of sensitivity of sagittal vein to vasoconstrictor effect of adrenaline. So, stress-related changes of the cerebral venous blood flow (CVBF) can be the source of this disease. In this paper registration CVBF was made with the help of commercially available Thorlabs Swept Source OCT System, using the correlation mapping method. In this method values of correlation coefficient of several images are analyzed. In the result of the algorithm the correlation map was obtained. By the resulting map the diameter of vessels was calculated, which is necessary for examination of effects of adrenalin to the vessels and identification symptoms of ICH.

    Background Plasma cholesteryl ester transfer protein (CETP) activity is often decreased in patients with hypothyroidism, whereas less is known about the phospholipid transfer protein (PLTP). We aimed to evaluate simultaneously serum CETP and PLTP activity in patients diagnosed with hypothyroidism. Material/Methods The selection criteria for control group members (without thyroid dysfunction) in this case to case study were levels of total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglycerides similar to those in study group patients (101 patients diagnosed with hypothyroidism). Serum CETP and PLTP activities were measured by homogenous fluorometric assays using synthetic donor particle substrates. Results Serum CETP and PLTP activities in hypothyreotic patients were lower (p<0.001) compared with those in healthy subjects. This lowering was associated with significant changes in HDL-C subclasses: decrease in HDL2- and increase in HDL3 cholesterol levels. Multiple linear regression analyses adjusted for age, sex, body mass index, smoking habits, and alcohol drinking showed a strong association between hypothyroidism and activity of lipid transfer proteins. A linear inverse relationship between thyroid-stimulating hormone (TSH) and CETP (r=−0.21; p<0.01) and between TSH and PLTP (r=−0.24; p<0.001) was shown. There also was a positive correlation (p<0.001) between CETP and HDL2 cholesterol (r=0.27) and between PLTP and HDL2 cholesterol (r=0.37). A negative correlation between CETP and HDL3 cholesterol (r=−0.22: p<0.01) and between PLTP and HDL3 cholesterol (r=−0.24; p<0.001) has been demonstrated as well. Conclusions The decreased HDL2 and increased HDL3 cholesterol levels in subjects with hypothyroidism are consequences of decreased activity of lipid transfer proteins. These changes are early symptoms of lipid disturbances in hypothyroidism. PMID:27899788

    Full Text Available The feeding diets were evaluated containing low and high levels of soybean oil for horses athletes subjected to two protocols of aerobic training on the response of basal blood biochemical parameters. Four horses were used in latin square design with treatments in a 2 x 2 factorial arrangement. Treatments consisted levels of 5 and 15% oil concentrates and two aerobic training, 40' and 60' minutes. Plasmatic parameters were monitored, triglyceride (TG, total cholesterol (TC, glucose (GLU and lactate (LAC, during basal metabolism. The TG, TC, GLU and LAC from horses at rest were not affected (P> 0.05 neither of diet and physical activity, 0.21, 3.79, 4.18, 0.93 mmol L-1, respectively. It can be concluded that offer concentrate with high content of soybean oil to athletic horses in aerobic activities can be performed without altering the blood biochemical profile of basal metabolism.

    Laser Doppler flowmetry (LDF) was used to measure bone blood flow in the rabbit femoral condyles. To correlate the LDF output signal blood cell flux to in vivo blood flow, simultaneous measurements using LDF and /sup 85/Sr-labeled microspheres were made in an adult rabbit model. There was no correlation between the two methods for blood flow in the femoral condyles and the correlation between the two methods for blood flow in the femoral head does not achieve statistical significance. An LDF signal of 0.4 V was approximately equal to a microsphere measured flow rate of 0.4 ml blood/g bone/min. The strength of the correlation in the latter case may have been affected by (a) large arteriovenous shunts, (b) inadequate mixing of the microspheres with a left ventricular injection, and (c) insufficient numbers of microspheres present in the bone samples. When LDF was used to evaluate the effect of elevated intracapsular pressure on femoral head blood flow in skeletally mature rabbits, femoral head subchondral bone blood flow declined with increasing intracapsular pressure from a baseline value of 0.343 +/- 0.036 to a value of 0.127 +/- 0.27 at 120 cm of water pressure. The decline in femoral head blood flow was statistically significant at pressures of 40 cm of water or higher (p less than 0.001), and evaluation of sections of the proximal femora made from preterminal disulphine blue injections confirmed these findings. Intracapsular tamponade has an adverse effect on femoral head blood flow beginning well below central venous pressure and should be considered in the pathophysiology of posttraumatic and nontraumatic necrosis of the femoral head. Laser Doppler flowmetry was easy to use and appears to be a reproducible technique for evaluating femoral head blood flow, offering distinct advantages over the microsphere technique for measuring bone blood flow.

    目的:了解抑郁症患者糖脂代谢以及应激情况。方法68例抑郁症患者作为抑郁症组,分别采用汉密顿抑郁量表(HAMD17)和汉密顿焦虑量表(HAMA14)、生活事件量表(LES)对患者情绪状况以及应激状况进行评定,监测其空腹血糖(FBG)、甘油三脂(TG)、血清总胆固醇(TC)、皮质醇(CO)水平,与40例对照组进行比较。结果抑郁症组的FBG、TG、CO水平显著高于对照组(P0.05);同时相关分析发现,抑郁症患者LES总分与FBG、CO水平呈正相关(P0.05). The results of related analysis showed that LES score of depression patients was positively correlated with levels of FBG and CO (P<0.05 or P<0.01), and the HAMA score, mental anxiety factors score and physical anxiety factors score were all positively correlated with level of TG. Conclusion The abnormal glucolipid metabolism of depression patients is related with their long-term mental stimulation. Therefore, clinicians ought to take early monitor on the patients’blood glucose, blood lipid and cortisol so as to provide timely treatment.

    Diabetes is a common metabolic disorder that is specified by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The use of nonpharmacological treatments (herbal agents) is a new approach in the management of diabetes. The aim of this study was to investigate the effect of aqueous extract of alfalfa on blood glucose and serum lipids in alloxan-induced diabetic rats. In this study, 32 female rats (210–250 g) were used which were divided randomly into 4 groups including intact control group, diabetic control group, and 2 diabetic groups which received 250 and 500 mg/kg doses of aqueous extract of alfalfa, respectively. In the diabetic groups, alloxan-monohydrate was injected peritoneally to create diabetic condition. The two last groups orally received aqueous extract of alfalfa for 21 days. At the end of experiment, sugar, cholesterol, triglycerides, high-density and low-density lipoprotein, and aspartate aminotransferase (ALT) and alanine aminotransferase (AST) levels were measured in the samples. Consumption of aqueous alfalfa extract significantly reduced glucose, cholesterol, triglycerides, and low-density lipoprotein (LDL) levels in the diabetic rats but enhanced high-density lipoprotein (HDL) levels. ALT and AST liver enzyme levels were also reduced in blood. Histological examination showed that the aqueous alfalfa extract caused reconstruction of damaged liver and enhanced Langerhans islets’ diameter in pancreas. Therefore, all signs of diabetes were improved by oral administration of alfalfa in defined dose. PMID:26525173

    The present study was aimed to investigate and compare the efficacy of duloxetine (DLX) loaded nanostructured lipid carriers (NLC) with DLX solution pharmacodynamically following intranasal administration. The study was further conducted to estimate DLX concentration in brain and blood. DLX was administered to albino Wistar rats either intranasally or orally in solution form (DLX solution) or encapsulated in NLC (DLX-NLC). These were evaluated in-vivo for pharmacodynamic studies for depression by forced swimming test and locomotor activity test. Intranasal DLX-NLC treatment exhibited improved behavioural analysis results (swimming, climbing, and immobility) than the DLX solution after 24 h of study. Furthermore, DLX-NLC significantly increased the total swimming and climbing time when compared with control and significantly reduced the immobility period. The intranasal DLX-NLC demonstrated improved locomotor activity when compared with DLX solution. Amount of DLX was quantified in blood and brain after the forced swimming test. The intranasal DLX-NLC demonstrated higher concentration in brain compared with DLX solution. Thus, intranasal DLX-NLC was found to be a promising formulation for the treatment of depression.

    Twenty-one patients with mild or moderate hypertension were randomised to receive either Atenolol 100 mg (N = 10) or Pindolol 15 mg (N = 11) in a once daily dosage over a two month period. The effects of these two betablockers on the blood pressure and plasma lipid profile were studied. Special attention was paid to the methodology: obese patients (30% over theoretical weight derived from the Lorenz formula) and those with pre-treatment triglyceride levels higher than 1.82 mmol/l were excluded because of the well documented biological instability of such patients. The selected patients were given placebo for two weeks. At the end of the placebo period those subjects whose body weight, total cholesterol, apolipoproteins or triglycerides had varied by more than 10%, 15% and 30% respectively, were also excluded from the study. At the end of the 60 days active treatment period, a comparable fall in the blood pressure was observed in both groups and there was no significant difference in the biological parameters as compared with pre-treatment values. In addition, the cardiovascular risk, evaluated by the B/A1 apolipoprotein ratio, increased in only one patient in the group receiving Atenolol and one patient receiving Pindolol.

    In contrast to the horse heart apocytochrome c,the chicken heart apocytochrome c under-went a conformational change from random coil to partial folding during a renaturation process.When theapocytochrome horse heart and that of chicken heart c were subjected to a translocation assay in vitro usinglarge trypsin-enclosed unilamellar vesicles from soybean phospholipids,the ability of the chicken heart apoc-ytochrome c to penetrate into the liposomes was found to decrease markedly with the renaturation procedure,while that of horse heart apocytochrome c remained relatively constant.Observations from circular dichroismmeasurement on the induction of secondary folding of these two species of apocytochrome c upon interactionwith soybean phospholipid vesicles suggested that a more flexible structure of apocytochrome c embedded inthe lipid matrix be required for its efficient translocation across the bilayer.

  3. Genetic influences on blood lipids and cardiovascular disease risk: tools for primary prevention.

    Genetic polymorphism in human populations is part of the evolutionary process that results from the interaction between the environment and the human genome. Recent changes in diet have upset this equilibrium, potentially influencing the risk of most common morbidities such as cardiovascular diseases, obesity, diabetes, and cancer. Reduction of these conditions is a major public health concern, and such a reduction could be achieved by improving our ability to detect disease predisposition early in life and by providing more personalized behavioral recommendations for successful primary prevention. In terms of cardiovascular diseases, polymorphisms at multiple genes have been associated with differential effects in terms of lipid metabolism; however, the connection with cardiovascular disease has been more elusive, and considerable heterogeneity exists among studies regarding the predictive value of genetic markers. This may be because of experimental limitations, the intrinsic complexity of the phenotypes, and the aforementioned interactions with environmental factors. The integration of genetic and environmental complexity into current and future research will drive the field toward the implementation of clinical tools aimed at providing dietary advice optimized for the individual's genome. This may imply that dietary changes are implemented early in life to gain maximum benefit. However, it is important to highlight that most reported studies have focused on adult populations and to extrapolate these findings to children and adolescents may not be justified until proper studies have been carried out in these populations and until the ethical and legal issues associated with this new field are adequately addressed.

    Full Text Available Abstract Background and aim Marine n-3 fatty acids and γ-linolenic acid both have anti-inflammatory effects and may be useful to help treat inflammatory diseases. The effects of these alone or combined were examined in patients with arthritis in a randomized controlled trial. Design Patients with rheumatoid arthritis or psoriatic arthritis were randomized into four groups in a double-blind, placebo-controlled parallel designed study. Patients received the respective capsules (1: 3.0 g n-3 LC-PUFA/d; 2: 3.2 g γ-linolenic acid/d; 3: 1.6 g n-3 LC-PUFA + 1.8 g γ-linolenic acid/d; 4: 3.0 g olive oil for a twelve week period. Clinical status was evaluated and blood samples were taken at the beginning and at the end of the period. Differences before and after intervention were tested with paired t-test or with Wilcoxon test for non-normal data distribution. Results 60 patients (54 rheumatoid arthritis, 6 psoriatic arthritis were randomised, 47 finished per protocol. In group 1, the ratio of arachidonic acid (AA/eicosapentaenoic acid (EPA decreased from 6.5 ± 3.7 to 2.7 ± 2.1 in plasma lipids and from 25.1 ± 10.1 to 7.2 ± 4.7 in erythrocyte membranes (p ≤ 0.001. There was no significant influence on AA/EPA ratio due to interventions in group 2-4. In group 2, the intake of γ-linolenic acid resulted in a strong rise of γ-linolenic acid and dihomo-γ-linolenic acid concentrations in plasma lipids, cholesteryl esters, and erythrocyte membranes. The combination of n-3 LC-PUFA and γ-linolenic acid (group 3 led to an increase of γ-linolenic acid and dihomo-γ-linolenic acid concentrations in plasma lipids, cholesteryl esters, and erythrocyte mem-branes. This increase was only half of that in group 2. Conclusions Incorporation of eicosanoid precursor FAs was influenced by an intake of n-3 LC-PUFA and γ-linolenic acid suggesting a possible benefit for therapy of chronic inflammatory diseases.

    We report the improvement of a method for the detection of ochratoxin A (OTA) and its thermal degradation product 2'R-ochratoxin A in dried blood spots (DBS) by high performance liquid chromatographic (HPLC) tandem mass spectrometry (MS/MS). The DBS technique was advanced for the analysis of these two compounds in DBS with unknown amounts of blood as well as varying hematocrit values. Furthermore the comparability of venous vs. capillary blood was investigated. Human whole blood samples were spotted, dried, and extracted with a solvent consisting of acetone, acetonitrile and water for analysis by HPLC-MS/MS. Quantification was carried out by stable isotope labelled internal standards. Blood samples of volunteers (n=50) were used to further optimize and simplify the procedure. Ochratoxin A and 2'R-ochratoxin A concentrations found in the entire spots (approx. 100 μL blood) were compared with punched DBS discs of 8.8mm size containing approximately 20 μL blood. As a result the amounts of both toxins in a punched 8.8mm disc correlate well with the entire DBS. Also the use of capillary blood from finger-pricks versus venous blood was evaluated. The analyte levels correlate as well indicating that the less invasive finger-prick sampling gives also reliable results. The influence of hematocrit was investigated in a range of 25-55% according to the hematocrit in the used real blood samples (34-46% hematocrit). However no significant hematocrit effect was observed for the utilized real blood samples. Moreover different blood volumes were spotted and punched as a minimal spot size is usually recommended for accurate analysis. In this experiment finger-prick samples typically consist of about 90 μL blood. Therefore spots of 75, 100 and 125 μL blood were prepared and analyzed. Similar to the hematocrit effect, no considerable influence was observed.

    Abstract The leaves of the persimmon tree (PL) are known to have beneficial effects on hyperglycemia, dyslipidemia, and nonalcoholic fatty liver disease. We recently demonstrated that PL had antithrombotic properties in vitro. However, little is known about the antiplatelet and anticoagulant properties of PL in vivo. Omega-3 fatty acid (n-3 FA)-containing fish oil has been widely prescribed to improve blood circulation. This study compared the effects of dietary supplementation with an ethanol extract of PL or n-3 FA on blood coagulation, platelet activation, and lipid levels in vivo. Sprague–Dawley rats were fed a high-fat diet with either PL ethanol extract (0.5% w/w) or n-3 FA (2.5% w/w) for 9 weeks. Coagulation was examined by monitoring the activated partial thromboplastin time (aPTT) and prothrombin time. We examined plasma thromboxane B2 (TXB2), serotonin, and soluble P-selectin (sP-selectin) levels. The aPTT was significantly prolonged in the PL and n-3 FA supplement groups. PL also attenuated the TXB2 level and lowered arterial serotonin transporter mRNA expression, although it did not alter plasma serotonin or sP-selectin levels. C-reactive protein and leptin levels were significantly reduced by PL and n-3 FA supplementation. In addition, PL decreased plasma total- and low-density lipoprotein-cholesterol levels, as did n-3 FA treatment. These results indicated that the PL ethanol extract may have the potential to improve circulation by inhibiting blood coagulation and platelet activation and by reducing plasma cholesterol levels.

    Full Text Available Objective  To explore the influence of intra-abdominal fat (IAF accumulation on ambulatory blood pressure (ABP. Methods  Four hundred and forty-eight hospitalized patients with cardiovascular and metabolic diseases, including 235 males and 213 females, aged 20-85 (55±12 years old, were enrolled in this study. The abdominal fatty thickness was measured with B-mode ultrasound. Simultaneously the patient received 24hABP monitoring. The patients were divided into excessive IAF group, normal group, and quintile subgroups according to the cut-off points (male 38.5mm, female 34.7mm for observing the difference in indexes of ambulatory blood pressure between different groups/subgroups. Results  The 24h mean systolic BP (24hMSBP, 24h mean BP (24hMBP, 24h mean diastolic BP (24hMDBP, daytime MSBP (dMSBP, daytime MBP (dMBP, daytime MDBP (dMDBP, nighttime MSBP (nMSBP, nighttime MBP (nMBP, night MDBP (nMDBP were significantly higher in the excessive IAF group than in the normal group (P < 0.05. However, the elevation of ABP was not a simple gradual linear elevation corresponding to a gradual increase in IAF thickness, but manifested an approximately U-shaped trend. Pearson correlation analysis showed IAF thickness was positively correlated with all the indexes of 24hABP, while partial correlation analysis after adjustment for age and sex showed IAF thickness was positively correlated with 24hSBP, 24hMBP, dMBP and nMBP. Conclusion  The relationship between IAF thickness and ABP presents a U-shaped curve, which may provide an enlightenment in controlling blood pressure by weight loss in clinical work.

    Full Text Available Objective: Multiple myeloma (MM is characterized by malignant proliferation of plasmocytes and their precursors. T regulatory cells (Tregs have a role in immunosuppression and control of autoimmunity, and are currently an important topic in the study of immune response to tumor cells. The correlation between Tregs and autologous peripheral blood stem cell transplantation (APBSCT in MM has not been studied. The aim of this study was to compare CD4+CD25+FOXP3+ Treg, CD200, and PD-1 levels in MM patients that did and did not undergo APBSCT. Materials and Methods: Peripheral blood samples were collected from 28 MM patients ranging in age from 41 to 78 years for analysis of CD4CD25+ FOXP3+ Tregs, PD-1 (CD279, and CD200. Peripheral blood mononuclear cells were isolated via density gradient centrifugation. Four-color flow cytometry was performed. Using a sequential gating strategy, Tregs were identified as CD4+CD25+FOXP3+ T-cells. Results were analyzed using the Mann Whitney U non-parametric test and a compare means test. p values 0.05. Conclusion: Treg levels were higher in the patients that underwent APBSCT. Tregs are crucial for the induction and maintenance of peripheral tolerance to self-antigens. In addition, Tregs can suppress immune responses to tumor antigens; however, APBSCT and Treg levels were not correlated with CD200 or PD-1 expression. Relationship of Tregs with prognosis needs to be determined by studies that include larger cohorts.

    Over the past decades, several in vitro methods have been tested for their ability to predict either human intestinal absorption (HIA) or penetration across the blood-brain barrier (BBB) of drugs. Micellar liquid chromatography (MLC) has been a successful approach for retention time measurements of drugs to establish models together with other molecular descriptors. Thus far, MLC approaches have only made use of commercial surfactants such as sodium dodecyl sulfate (SDS) and polyoxyethylene (23) lauryl ether (Brij35), which are not representative for the phospholipids present in human membranes. Miltefosine, a phosphocholine-based lipid, is presented here as an alternative surfactant for MLC measurements. By using the obtained retention factors and several computed descriptors for a set of 48 compounds, two models were constructed: one for the prediction of HIA and another for the prediction of penetration across the BBB expressed as log BB. All data were correlated to experimental HIA and log BB values, and the performance of the models was evaluated. Log BB prediction performed better than HIA prediction, although HIA prediction was also improved a lot (from 0.5530 to 0.7175) compared to in silico predicted HIA values.

    Full Text Available Background. Age-related decrease in bone marrow erythropoietic capacity is often accompanied by the telomere length shortening in peripheral white blood cells. However, limited and conflicting data hamper the conclusive opinion regarding this relationship. Therefore, the aim of this study was to assess an association between telomere length and peripheral blood cell count parameters in the Polish elderly population. Material and Methods. The substudy included 1573 of 4981 subjects aged 65 years or over, participants of the population-based PolSenior study. High-molecular-weight DNA was isolated from blood mononuclear cells. Telomere length (TL was measured by QRT-PCR as abundance of telomere template versus a single gene copy encoding acidic ribosomal phosphoprotein P0. Results. Only white blood count (WBC was significantly different in TL tertile subgroups in all subjects (P=0.02 and in men (P=0.01, but not in women. Merely in men significant but weak positive correlations were found between TL and WBC (r=0.11, P<0.05 and RBC (r=0.08, P<0.05. The multiple regression analysis models confirmed a weak, independent contribution of TL to both RBC and WBC. Conclusions. In the elderly, telomere shortening limits hematopoiesis capacity to a very limited extent.

    Full Text Available Aim: To find out the co-relation between polycystic ovary syndrome (PCOS with blood group & diet in South Indian females, between the age-group of (20-30 years. Objectives: Correlative analysis of ABO & Rh system, dietary habits & alcohol consumption with PCOS. Materials & Methods: 100 patients between (20-30 years, diagnosed with PCOS were selected. A standard PCOS questionnaire was given. Blood group & dietary status data were collected. Patients were grouped according to ABO & Rh system considering their diet & alcohol intake (p≤0.05 significant. Result: Our data revealed that the highest risk of PCOS was observed in females with blood group ‘O’ positive followed by ‘B’ positive who were on mixed diet & used to consume alcohol. Our study also suggests that Rh negative individuals didn’t show any association with PCOS. Conclusion: The results of our study suggest that ‘O’ positive females, are more prone to PCOS. Though the relative frequency of B positive individuals are more in India, females with blood group O positive are more susceptible to PCOS, contributing factors being mixed diet & alcohol intake. So, early screening of ‘O’ positive &‘B’ positive females of reproductive age-group in South-India, could be used as a measure for timely diagnosis of PCOS, better management &also prevention of complications. However, further research should be done to investigate the multifaceted mechanisms triggering these effects.

    Results: The study showed that, plasma Zn and Se concentrations were lower in haemodialysis patients compared to that of healthy controls, while plasma Cu, MDA and Cu/Zn ratio were higher. Plasma Cu/Zn ratios were positively correlated to MDA and weakly correlated to hs-CRP levels whereas plasma Se concentrations were inversely correlated to MDA. In addition, MDA levels increased after haemodialysis session. Conclusions: Based on the results of the present study regarding the imbalance of trace elements in haemodialysis patients, it seems reasonable to periodically assess the trace elements status and consider possible correctional therapy in case of deficiency.

    The purpose of this study is to find the correlation between middle latency auditory evoked potentials (MLAEP) and sound activated single photon emission computed tomography (SPECT) studies. This study was performed on six normal right-handed volunteers with a mean age of 35.2{+-}7.6 years, using the split-dose technique. First, a SPECT study was performed on subjects in blinded, awake and silent states. After bilateral ears were stimulated with a click sound, MLAEP and a second SPECT study were performed. Subtraction of the first SPECT from the second SPECT revealed a statistically significant increase of cerebral blood flow (CBF) in the bilateral superior temporal region. Bilateral Na amplitudes of MLAEP had a statistically significant and good correlation with the percentages of CBF changes in the bilateral superior temporal region. The superior temporal cerebral blood flow activation can be expressed by electrophysiological activation. Moreover, correlation during the left Na components and left frontal and occipital lobe are discussed. (author)

    The current study aimed to investigate the association between telomere length in peripheral blood leukocytes and kidney function in various age groups of a healthy population. A total of 139 healthy individuals were divided into five groups according to their age: 35‑44, 45‑54, 55‑64, 65‑74 and >75 years old. Peripheral blood leukocytes were obtained and the telomere restriction fragment (TRF) length was assayed using a digoxigenin‑labeled hybridization probe in Southern blot assays. Laboratory assays of kidney function were also performed. A correlation was observed between TRF length and age (r=‑0.314, Ptelomere length of the individuals >75 years group being significantly shorter than the telomere length of the 35‑44, 45‑54 and 55‑64 years age groups (Plength for males versus females did not differ for any of the age groups, while a correlation was observed between TRF length and serum levels of cystatin C (r=‑0.195, Plength and glomerular filtration rate (r=‑0.184, Ptelomere length reduced with age and was correlated with serum levels of cystatin C and glomerular filtration rate. Therefore, TRF length is associated with kidney function and may serve as a marker of aging.

    Background Studies have shown that complications in type 1 diabetes mellitus (T1DM) in children are mainly due to oxidative stress (OS).Lipid peroxidation is the main marker of OS and iso-prostaglandin is a reliable biomarker of lipid peroxidation in type 2 diabetes mellitus (T2DM).However,there have been few studies on OS in T1DM children with hyperglycemia and glucose fluctuations.Methods We prospectively enrolled 23 newly diagnosed T1DM patients and 23 age and sex matched healthy controls in Beijing Children's Hospital from May 2010 to January 2011.They were treated with continuous subcutaneous insulin injection (CSII) and monitored by continuous glucose monitoring system (CGMS).Twenty-four-hour urine samples were collected to measure the concentration of 8-iso prostaglandin F2α (8-isoPGF2α).Samples taken from diabetic children were collected at days 8 to 10 after insulin treatment.Intraday glucose fluctuations were assessed by mean amplitude of glucose excursions (MAGE),largest amplitude of glycemic excursions (LAGE),standard deviation of blood glucose (SDBG) and number of glycemic excursions (NGE).The correlations between glucose parameters and the index of oxidative stress were analyzed.Results Urine 8-isoPGF2α in the T1DM group was higher than that in the control group ((967.70±412.68) ng vs.(675.23±354.59) ng,P=0.019).There was a correlation between urine 8-isoPGF2α level and MAGE (r=0.321,P=-0.039),a significant correlation between low-density lipoprotein and urine 8-isoPGF2α level (r=0.419,P=0.03).There was no significant correlation between urine 8-isoPGF2α level and blood pressure,glycosylated hemoglobin (HbA1c),fasting C-peptide or other lipid indices.Conclusion A correlation between urine 8-isoPGF2α levels and MAGE and low-density lipoprotein was found in children newly diagnosed with T1DM.

    2009-01-01

    The purpose of this research project was to determine whether the glucose level of a blood plasma sample from a diabetic patient could be predicted by measuring the density and conductivity of ultrafiltrate of plasma created by a 30,000 m.w. cutoff membrane. Conductivity of the plasma filtrate measures electrolyte concentration and should correct density measurements for changes in electrolytes and water concentration. In vitro studies were performed measuring conductivity and density of solutions of varying glucose and sodium chloride concentrations. Plasma from seven hospitalized patients with diabetes was filtered across a 30,000 m.w. cutoff membrane. The filtrate density and conductivity were measured and correlated to glucose levels. In vitro studies confirmed the ability to predict glucose from density and conductivity measurements, in varying concentrations of glucose and saline. In plasma filtrate, the conductivity and density measurements of ultrafiltrate allowed estimation of glucose in some patients with diabetes but not others. The correlation coefficient for the combined patient data was 0.45 which was significant but only explained 20% of the variability in the glucose levels. Individually, the correlation was significant in only two of the seven patients with correlation coefficients of 0.79 and 0.88. The reasons for lack of correlation are not clear, and cannot be explained by generation of idiogenic osmoles, effects of alcohol dehydrogenase, water intake, etc. This combination of physical methods for glucose measurement is not a feasible approach to measuring glucose in plasma filtrate.

Los promedios fueron: CT: 159,2 ± 28,3, CHDL: 51,9 ± 12,1, LDL: 89,0 ± 31,5 y TG: 93,2 ± 60 mg/dL. Los hombres tuvieron mayor CHDL: 53,3 ± 12,2 vs 50,6 ± 11,8 mg/dL y menor TG: 86,2 ± 58,2 vs 99,5 ± 61,7 mg/dL que las mujeres (p < 0,001). Con regresión múltiple se encontró influencia del estado nutricional y edad en todos los lípidos y del sexo en la mayoría. Comparados con la referencia hubo concordancia en CT y CLDL, pero los niños chilenos presentaron mayores niveles de TG sobre el percentil 50 y menores niveles de CHDL bajo percentil 50. Conclusiones: Las concentraciones de lípidos sanguíneos estuvieron influidas por el estado nutricional, edad y sexo. En comparación a la referencia, se encontró un patrón de mayor riesgo cardiovascular en los niños chilenos.

    PCBs have numerous toxic effects on laboratory animals, namely hepatotoxicity, immunotoxicity, reproductive and hormonal effects, mutagenic and carcinogenic potency (Safe 1984). They have been recognized as potent inducers of many microsomal drug metabolizing enzymes in several species. Moreover, treatment of rats with PCBs gave rise to altered lipid metabolism with accumulation of lipids in the liver. In most of these studies male rats have been used. However, sex differences in the effects of xenobiotics on microsomal drug metabolizing enzymes have been shown particularly with PCBs and little was known about differences in the effects of PCBs on lipid metabolism. This study was designed to investigate the effects of a subchronic treatment with Phenochlor DP5 on some microsomal drug metabolizing enzyme activities and on liver and blood lipids of male and female rats. The long-term effects of DP5 administration during pre and postnatal period on adult microsomal enzyme activities and liver and blood lipids of both sexes have also been studied. A possible xenobiotic imprinting of the hepatic monooxygenase system during neonatal period has been shown recently, and it has been recognized that some functional defects which often manifest themselves in adult period may be induced prenatally or before weaning.

    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.

    This study examined the associations of diabetes-related distress (DRD), depressive symptoms, health-related quality of life (HRQoL), and medication adherence with glycemia, blood pressure (BP), and lipid biomarkers in adults with type 2 diabetes mellitus (T2D). This cross-sectional study was conducted in three Malaysian public health clinics in 2012-2013, recruited adult patients (aged ≥30 years) with T2D who had been diagnosed for more than one year, were on active follow-up, and had recent blood test results. Univariable and multivariable analyses were performed to identify significant associated factors for glycated hemoglobin (HbA1c) BP, and lipids. The response rate was 93.1% (700/752). The majority were females (52.8%), Malay (52.4%), and married (78.7%). DRD correlated with systolic BP (r= -0.16); depressive symptoms correlated with low-density lipoprotein cholesterol (r=0.12) and total cholesterol (r=0.13); medication adherence correlated with HbA1c (r= -0.14) and low-density lipoprotein cholesterol (r= -0.11); and HRQoL correlated with casual blood glucose (r= -0.11), high-density lipoprotein cholesterol (r= -0.13), and total cholesterol (r= -0.08). Multivariable analyses showed that HRQoL was significantly associated with casual blood glucose (adjusted B= -0.06, P=0.024); DRD was associated with systolic BP (adjusted B= -0.08, P=0.066); depressive symptoms were associated with low-density lipoprotein cholesterol (adjusted B=0.02, P=0.061), and medication adherence was associated with HbA1c (adjusted B= -0.11, P=0.082) and total cholesterol (adjusted B= -0.06, P=0.086). There were significant and distinctive associations of DRD, depressive symptoms, HRQoL, and medication adherence with glycemia, BP, and lipid biomarkers. Unexpected beneficial therapeutic effects of DRD on BP require further study. A multidisciplinary approach may be needed for risk management in adults with T2D at the primary care level.

    Full Text Available Background: The correlation between certain systemic diseases and ABO blood group is a well-documented fact. The association between periodontal disease and ABO blood group is not studied in relation to a specific geographic location. Here is a study conducted on a group of patients belonging to South Kanara district of Karnataka state. Materials and Methods: A total of 750 subjects aged between 30and 38 years belonging to South Kanara district were selected on random basis. The study subjects were segregated into healthy/mild gingivitis, moderate/severe gingivitis, and periodontitis group, based on Loe and Silness index and clinical attachment loss as criteria. The study group was further categorized and graded using Ramfjord′s periodontal disease index. Blood samples were collected to identify ABO blood group. Results: Prevalence of blood group O was more in South Kanara district, followed by blood groups B and A, and the least prevalent was AB. The percentage distribution of subjects with blood groups O and AB was more in healthy/mild gingivitis group (group I and moderate/severe gingivitis group (group II, while subjects with blood groups B and A were more in periodontitis group III. There was increased prevalence of subjects with blood groups O and AB with healthy periodontium, while subjects with blood groups B and A showed inclination toward diseased periodontium. Conclusion: There is a correlation existing between periodontal disease and ABO blood group in this geographic location. This association can be due to various blood group antigens acting as receptors for infectious agents associated with periodontal disease. This broad correlation between periodontal disease and ABO blood group also points toward susceptibility ofthe subjects with certain blood groups to periodontal disease.

    Pythons are unique amongst snakes in having different pressures in the aortas and pulmonary arteries because of intraventricular pressure separation. In this study, we investigate whether this correlates with different blood vessel strength in the ball python Python regius. We excised segments from the left, right, and dorsal aortas, and from the two pulmonary arteries. These were subjected to tensile testing. We show that the aortic vessel wall is significantly stronger than the pulmonary artery wall in P. regius. Gross morphological characteristics (vessel wall thickness and correlated absolute amount of collagen content) are likely the most influential factors. Collagen fiber thickness and orientation are likely to have an effect, though the effect of collagen fiber type and cross-links between fibers will need further study.

    Full Text Available BACKGROUND Osteoporosis is a condition where the structural and functional integrity of the bones are altered to an extent where the bone material is not sufficiently completed enough to perform its basic function of support, load bearing and component of metabolic pool of osteogenic minerals. METHODS The study was conducted in a group of 50 women (25 cases and 25 controls irrespective of age from different socio-economic status. As per plan of study, the target population was divided into two main groups. The first group was defined as the control group and the other group as the experimental or test group who were admitted in orthopaedic unit of Gauhati Medical College and Hospital with different type of clinical manifestations of osteoporotic disease, the diagnosis of which were made on the basis of x-ray findings, provided the clinical examination and laboratory procedures are in agreement. RESULTS In our study, the mean fasting serum TG, HDL and VLDL values are significantly high (P<0.01 and the LDL value is significantly low in the women with osteoporosis in relation to normal control group. Total cholesterol values in osteoporotic group is apparently 6.07% lower than the mean total cholesterol in the normal control group. Osteogenic minerals represented by calcium, phosphate and magnesium show significant elevation (P<0.01 of mean serum concentration in the osteoporotic group than the normal control group. CONCLUSION Observed changes and relationship between the lipid profile and mineral status in serum in osteoporosis are indicative of an ongoing rearranging process in an altered metabolism, which is primarily aimed at diminishing its pace towards the associated complications indicated by attempted lowering of circulating cholesterol and maintenance of serum minerals within normal limits with assistance from a hormonal axis composed of components from metabolic-reproductive hormonal axis responsible for modulating natural aging process.

    The precursor state for cholesterol gallstone formation is cholesterol-saturated bile. We studied a high-risk group for cholesterol gallstones to determine whether dietary variables affect bile cholesterol. Bile samples were analyzed from 46 Micmac Indian women without gallstones and 13 with gallstones for molar percentage cholesterol (MPC) and bile acid composition. The data were analyzed by multiple regression analysis with MPC as the dependent variable and the dietary variables, obtained from four consecutive-day food records, and biliary bile acid composition as the independent variables. In the 46 women without gallstones, obesity, calorie range/calorie intake, and iron and calcium intake were, in their order of importance, significant factors. In normal weight subjects (ponderal index > 12.5) relative obesity was still a significant correlate. Obesity and iron intake were positive correlates while calorie range/calorie intake and calcium intake varied inversely. When the effect of obesity was controlled, these factors were still significant in this group, as they were in the gallstone group. In addition, the duration of overnight fast obtained by history, together with the proportions of deoxycholic and chenodeoxycholic acids in bile were correlates of the biliary molar percentage cholesterol.

    Some studies focused on the effect of the dietary glycemic index on lipoproteins and apolipoproteins in adults; however, little evidence exists among adolescents regarding the effect of a low glycemic index (LGI) diet on apolipoproteins and lipoprotein (a) (Lpa). This study was conducted to evaluate the effect of an LGI diet on the lipid profile, apolipoproteins and Lpa among overweight and obese adolescent girls. For this parallel designed randomized clinical trial, 50 healthy overweight/obese girls at pubertal ages were randomly allocated to an LGI or a healthy nutritional recommendations (HNR) based diet. Equal macronutrient distributed diets were prescribed to both groups. Biochemical measurements included lipid profile, apolipoprotein A, apolipoprotein B and Lpa were conducted before and after 10 weeks of intervention. Forty one adolescent girls completed the study. The dietary glycemic index in the LGI group was 42.67 ± 0.067. There were no differences in the mean of blood lipid indices baseline and after intervention between two groups. There were no significant differences between the two groups regarding lipid profiles, apolipoproteins and Lpa. There were no significant differences in lipid profiles, apolipoproteins and Lpa between the LGI diet and the HNR-based diet and the impact of these two diets on lipid profile was equal in this trial.

    Full Text Available Introduction: Diabetic people are more at risk of diseases such as vascular, kidneys and eye diseases, compared with normal people. Since Vit C competitively replaces glucose in most chemical reactions; so inhibit on non enzymatic glycosylation such as hemoglobin and lipoproteins, it seems that Vit C can be effective to prevent diabetic complications .In this study effect of Vit C supplements on blood sugar and fats level in type II diabetic patients was investigated. Methods: This study was conducted as a clinical trial using paired random sampling on 136 type II diabetic patients. At first, the patients weights, age, type of diet were recorded .Then their fasting blood glucose (FBS, glycosylated hemoglobin (HbAIC, Cholesterol, triglyceride, HDL and LDL were measured. After that the patients were divided in two randomized groups. The first group (control was subject of administration of Vit C supplement (1250 mg, 5 times a day, for a period of 3 months and the second group received placebo. Data were analyzed by paired t- test and SPSS Software. Results: In this study most of patients were women (62.2% of control group and 64.7% of placebo group. The mean age between the control group and placebo group were reported 51.2 ± 6.8 and 50.37± 9.71 years respectively. At the end of study , after 3 months of administration of Vit C supplement to control group, the mean concentration of FBS, LDL triglyceride Cholesterol and glycosylated hemoglobin has been reduced significantly with respect to the placebo group and the mean value of HDL has been increased as well. Conclusion: The finding shows that Vit C supplements might reduce the amount of glucose, lipids and glycosylated hemoglobin in patients with type 2 diabetes. Therefore, its consumption in diabetic patients can be recommended and as a result patient complications will be significantly reduced.

    Agave nectar is a fructose-rich liquid sweetener derived from a plant, and is often promoted as a low glycemic alternative to refined sugar. However, little scientific research has been conducted in animals or humans to determine its metabolic and/or health effects. The aim of this study was to explore the influence of agave nectar versus sucrose on weight gain, adiposity, fasting plasma blood glucose, insulin, and lipid levels. Eighteen (n=18) male ICR mice (33.8±1.6 g) were divided into two groups (n=6 for agave nectar and n=12 for sucrose) and provided free access to one of two diets of equal energy densities differing only in a portion of the carbohydrate provided. Diets contained 20% carbohydrate (by weight of total diet) from either raw agave nectar or sucrose. Epididymal fat pads were excised, and blood was collected after 34 days. Weight gain (4.3±2.2 vs. 8.4±3.4 g), fat pad weights (0.95±0.54 vs. 1.75±0.66 g), plasma glucose (77.8±12.2 vs. 111.0±27.9 mg/dL), and insulin (0.61±0.29 vs. 1.46±0.81 ng/mL) were significantly lower (P≤.05) for agave nectar-fed mice compared to sucrose-fed mice respectively. No statistically significant differences in total cholesterol or triglycerides were detected. These results suggest that in comparison to sucrose, agave nectar may have a positive influence on weight gain and glucose control. However, more research with a larger sample of animals and/or with human subjects is warranted.

    There is increasing evidence that oxidative stress (OS) plays a major role in the pathogenesis of diabetes mellitus (DM) and the development of its complications. As one of the consequences of OS is increased lipid peroxidation (LP), the aim of our studies was to check, how the activity of 2 enzymes involved in the detoxification of aldehydes formed during LP, glutathione S-transferase (GST) and aldehyde dehydrogenase 1 (ALDH 1) is changed in patients suffering from DM.GST and ALDH1A1 activities were determined in whole blood samples of DM type 2 patients (n=64) and healthy controls (n=60) using spectrophotometer (for GST activity) and fluorometer (for ALDH1 activity) and they were found to be significantly increased in diabetics when compared with healthy control (p<0.05). Intriguingly, grouping the DM patients on the basis of the glucose level and HbA1c revealed unusually low ALDH activity in the group of patients (n=16) with a relatively high level of these 2 parameters.The increase of ALDH1A1 and GST activity in DM seems to be associated with the severity of the disease and might be a compensatory effect against oxidative stress. Surprisingly low ALDH activity in DM patients with relatively high glucose and HbA1c levels can be a factor predisposing to the development of diabetic complications.

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

    Full Text Available Endothelin1 (ET-1 is a 21-amino acid peptide produced by the vascular endothelium under hypoxia, that acts locally as regulator of vascular tone and inflammation. The role of ET-1 in Plasmodium falciparum malaria is unknown, although tissue hypoxia is frequent as a result of the cytoadherence of parasitized red blood cell (pRBC to the microvasculature. Here, we show that both synthetic and endothelial-derived ET-1 are removed by parasitized RBC (D10 and W2 strains, chloroquine sensitive, and resistant, resp. and native haemozoin (HZ, malaria pigment, but not by normal RBC, delipidized HZ, or synthetic beta-haematin (BH. The effect is dose dependent, selective for ET-1, but not for its precursor, big ET-1, and not due to the proteolysis of ET-1. The results indicate that ET-1 binds to the lipids moiety of HZ and membranes of infected RBCs. These findings may help understanding the consequences of parasite sequestration in severe malaria.

    Coating nanoparticles with the surfactant Tween 80 have been previously shown to enhance drug delivery across the blood-brain barrier (BBB). The aim of this study was to investigate whether Tween 80 could be used to stabilise phytantriol-based cubosomes thereby enabling potential application in delivering macromolecular therapeutics to the brain. Cubosome particles with their large internal and external surface area by virtue of their nanostructure are ideal for delivery of macromolecules. Phase behaviour studies were conducted using a combination of optical microscopy and small-angle X-ray scattering (SAXS) and the addition of Tween 80 to mixtures of phytantriol and water resulted in a rich array of lyotropic mesophases. In particular, a large cubic phase region and a two-phase region of readily dispersed cubosomes is observed. Cubosomes with different concentrations of Tween 80 and phytantriol as the liquid crystal forming lipid were prepared using the solvent precursor method and their physical properties were investigated. A combination of dynamic light scattering, cryogenic electron tomography and SAXS shows formation of well-defined cubosomes with a narrow size distribution and the Im3m cubic structure. Collectively, the results confirm that Tween 80 can effectively stabilize phytantriol cubosomes, opening the possibility for future application in drug delivery across the BBB. Moreover, well-defined, homogenous cubosome formulations prepared using the mild solvent precursor dilution method has significant implications for large-scale production of cubosomes, which currently is a major barrier to the application of cubosomes in the clinic.

    Carmustine (BCNU)-loaded solid lipid nanoparticles (SLNs) were grafted with 83-14 monoclonal antibody (MAb) (83-14 MAb/BCNU-SLNs) and applied to the brain-targeting delivery. Human brain-microvascular endothelial cells (HBMECs) incubated with 83-14 MAb/BCNU-SLNs were stained to demonstrate the interaction between the nanocarriers and expressed insulin receptors (IRs). The results revealed that the particle size of 83-14 MAb/BCNU-SLNs decreased with an increasing weight percentage of Dynasan 114 (DYN). Storage at 4 °C for 6 weeks slightly deformed the colloidal morphology. In addition, poloxamer 407 on 83-14 MAb/BCNU-SLNs induced cytotoxicity to RAW264.7 cells and inhibited phagocytosis by RAW264.7 cells. An increase in the weight percentage of DYN from 0% to 67% slightly reduced the viability of RAW264.7 cells and promoted phagocytosis. Moreover, the transport ability of 83-14 MAb/BCNU-SLNs across the blood-brain barrier (BBB) in vitro enhanced with an increasing weight percentage of Tween 80. 83-14 MAb on MAb/BCNU-SLNs stimulated endocytosis by HBMECs via IRs and enhanced the permeability of BCNU across the BBB. 83-14 MAb/BCNU-SLNs can be a promising antitumor drug delivery system for transporting BCNU to the brain.

    To elucidate the participation of the brain regions in language function, cerebral blood flow (CBF) which were measured with positron emission tomography (PET) were compared with the language scores based on the standard language test for aphasics in 97 right-handed patients with aphasia due to cerebral infarction. PET studies were performed on 71.4{+-}107.3 days after onset. By the linear regression analysis, the aphasic scores were correlated with the regional CBF from 55 brain regions. CBF from the left frontal, left temporal, and left parietal lobes significantly correlated with language scores of auditory comprehension, speaking, reading, writing, calculation, and repetition. Highly significant correlation was obtained from the left posterior inferior frontal, superior temporal, supramarginal and angular gyri. CBF from the right inferior frontal, right superior temporal, right parahippocampal and right anterior cingulate gyri also correlated with the auditory comprehension, speaking and reading. Accordingly, in addition to the classical language areas which play an essential roles in language function, the extensive areas in the left hemisphere and some part of the right hemisphere may be related to the language processing and recovery from aphasia.

    Conjugated linoleic acid (CLA) may decrease adiposity and improve blood lipid profiles under some conditions. The goal of this study was to determine the effects of CLA supplementation on blood lipid profiles and adiposity of rats fed a diet containing a primarily saturated fat versus a diet containing a primarily unsaturated fat. Twenty-eight male Sprague-Dawley rats were randomly assigned to one of four diets containing coconut oil, coconut oil with CLA, corn oil or corn oil with CLA. After 28 days, blood was collected and serum concentrations of total cholesterol (TC), HDL-cholesterol (HDL-C), and triacylglycerols (TG) were assessed. Food intake, body weights, and epididymal fat pads were measured. No significant differences (p>0.05) were noted among groups for amount of food consumed, weight gained, food efficiency ratio or serum TG concentrations. TC concentrations were lower (pHDL-C was lower (p0.05) for CLA supplemented groups. Epididymal fat pads weighed significantly more (p0.05) between the corn oil and coconut oil + CLA group. Overall, this study suggests that CLA is more beneficial for control of blood lipids and adiposity when supplemented to a diet rich in saturated versus unsaturated fat.

    n--3 Fatty acids derived from fish oil reduce plasma triacylglycerols (triglycerides) and increase HDL-C (high-density lipoprotein cholesterol); however, the effect of n--3 fatty acid supplementation during pregnancy, a hyperlipidaemic state, remains unknown. We took the opportunity to investigate maternal lipid levels and blood pressure during and after pregnancy, and fetal lipid levels at birth, in a study that aimed primarily to examine the effect of fish oil supplementation during pregnancy on immune function in infants born to women with allergic disease. Eighty-three pregnant women who had allergic disease, but were otherwise healthy, completed the study. They were randomly allocated to receive fish oil or olive oil capsules, taken as 4 g/day, from 20 weeks of pregnancy until delivery. Compared with olive oil, fish oil supplementation did not alter triacylglycerols, total cholesterol, LDL-C (low-density lipoprotein cholesterol) or HDL-C during or after pregnancy. There was also no effect of fish oil on cord blood triacylglycerols, total cholesterol, LDL-C or HDL-C. Fish oil supplementation during pregnancy did not alter maternal blood pressure during or after pregnancy. The effects of fish oil on lipids and blood pressure in non-pregnant individuals appear to be lost when it is administered during pregnancy.

    Full Text Available The new GIFT (Genetically Improved Farmed Tilapia strain of Nile tilapia is a popular cultivated fish in Asia, but intensive aquaculture using nutritionally imbalanced feed has led to disorder of lipid metabolisms. An 8-week feeding experiment was conducted in order to assess the effects of different levels of L-carnitine (0, 200, 400, 600, and 800 mg/kg and dietary protein (22, 25, and 28% on blood sugar and blood lipid contents of the new juvenile GIFT strain of Nile tilapia. Results showed that dietary protein and L-carnitine had significant influences on glucose (GLU, high-density lipoprotein–cholesterol (HDL-C, total cholesterol (TC, triglyceride (TG, and low-density lipoprotein–cholesterol (LDL-C in the blood serum. The contents of GLU and HDL-C increased with the increases in dietary protein and L-carnitine levels, while the contents of TC, LDL-C, and TG decreased with the increases in dietary protein and L-carnitine levels. The interactive effect of both dietary protein and L-carnitine was most significant on GLU (p = 0.0001, followed by TG (p = 0.001, TC (p = 0.005, HDL-C (p = 0.056, and LDL-C (p = 0.109. These results suggested that high levels of dietary protein and L-carnitine supplementation reduce blood lipids and the burden of the fish liver.

    Full Text Available Background: Coronary Heart Disease is commonly associated with obesity, raised serum lipid levels and changes in blood pressure. The present study was designed to assess the effect of low fat- high calcium, and low fat- high fiber diets on weight reduction, lipid profile and blood pressure.Methods: The study sample consisted of 136 referred patients adult, obese men aged 53-64 years. Samples randomly were subdivided in two groups. Group 1 was advised 1600 calories, 20% fat, 1600 mg calcium rich diet and group 2 followed similar diet as for group 1 except a total daily intake of 55g fiber and 900 mg calcium per day for 12 weeks. Blood samples were collected and assayed for total cholesterol, LDL-cholesterol, HDLcholesterol and TG. Anthropometric assessments included measurement of weight, height, and waist circumferences followed by calculating Body mass index. Systolic and diastolic blood pressures were measured by using sphygmomanometer. Statistical analysis was performed with parametric and non-parametric methods as appropriate.Results: Data analysis revealed a significant decrease in total cholesterol, LDL-cholesterol, and TG in two groups, without any significant changes in HDL-cholesterol. Weight and blood pressure decreased in two groups, but the rate of reduction in blood pressure, weight and waist circumference were more significant in group 1 compared to group 2.Conclusion: An increase in dietary calcium intake, together with a Low calorie, low-fat diet can increase lipolysis in fat tissues, make greater weigh loss, ameliorate blood pressure, improve lipid levels, and reduce the risk of coronary vascular diseases.

    Liposomal formulations of the highly hydrophobic photosensitizer temoporfin were developed in order to overcome solubility-related problems associated with the current therapy scheme. We have incorporated temoporfin into liposomes of varying membrane composition, cholesterol content, and vesicle size. Specifically, two phosphatidyl oligoglycerols were compared to PEG2000-DSPE with respect to the ability to prolong circulation half life of the liposomal carrier. We measured the resulting pharmacokinetic profile of the liposomal carrier and the incorporated temoporfin in a rat model employing a radioactive lipid label and (14)C-temoporfin. The data for the removal of liposomes and temoporfin were analyzed in terms of classical pharmacokinetic theory assuming a two-compartment model. This model, however, does not allow in a straightforward manner to distinguish between temoporfin eliminated together with the liposomal carrier and temoporfin that is first transferred to other blood components (e. g. plasma proteins) before being eliminated from the blood. We therefore additionally analyzed the data based on two separate one-compartment models for the liposomes and temoporfin. The model yields the ratio of the rate constant of temoporfin elimination together with the liposomal carrier and the rate constant of temoporfin elimination following the transfer to e. g. plasma proteins. Our analysis using this model demonstrates that a fraction of temoporfin is released from the liposomes prior to being eliminated from the blood. In case of unmodified liposomes this temoporfin release was observed to increase with decreasing bilayer fluidity, indicating an accelerated temoporfin transfer from gel-phase liposomes to e. g. plasma proteins. Interestingly, liposomes carrying either one of the three investigated surface-modifying agents did not adhere to the tendencies observed for unmodified liposomes. Although surface-modified liposomes exhibited improved pharmacokinetic

    BACKGROUND Approximately 10% of attempted blood donations are not allowed because of low hemoglobin deferral. STUDY DESIGN AND METHODS Low hemoglobin deferrals were tracked in over 715,000 whole blood donors at six blood centers across the United States. A multivariable logistic regression model was developed to comprehensively assess demographic correlates for low hemoglobin deferral. RESULTS Demographic factors significantly associated with low hemoglobin deferral include female gender (11 times greater odds than males), increasing age in men (men over 80 have 29 times greater odds than men under 20); African American race (2–2.5 times greater odds than Caucasians); Hispanic ethnicity in women (1.29 times greater odds than Caucasian women) and weight in men (men under 124 pounds have 2.5 times greater odds than men over 200 pounds). Interestingly, increasing donation frequency is associated with decreased odds for low hemoglobin deferral (women with 1 donation in the previous 12 months have 2 times greater odds than those with 6 donations). CONCLUSIONS Low hemoglobin deferral is associated with female gender, older age, African-American race/ethnicity and lower body weight in men. An inverse association with donation frequency suggests a selection bias in favor of donors able to give more frequently. These data provide useful information that can be utilized to manage blood donors in order to limit low hemoglobin deferrals and assist in policy decisions such as changing the hemoglobin cut-off or permissible frequency of donation. They also generate hypotheses for new research of the causes of anemia in defined groups of donors. PMID:20412525

    This study investigated the effect of Cordyceps sinensis biomass supplementation obtained from submerged fermentation on blood lipid and low testosterone induced by high-fat diet (HFD). The experiments were carried out using a long-term intake of HFD and HFD plus Simvastatin or C. sinensis (4 months). Our results show that plasma cholesterol, triglycerides and LDL were decreased by Cordyceps sinensis biomass supplementation (CSBS). A long-term intake of HFD caused a significant liver damage which has been reverted by CSBS. CSBS normalized decreasing testosterone levels observed in high-fat diet feed rats. All these findings lead us to suggest that C. sinensis was able to decrease blood lipid concentration, increase hepatoprotective activity and normalize testosterone levels. PMID:27847459

    Shifts in lipid, catecholamine, and blood coagulation systems following various periods (1, 2, 3, and 4 months) of experimentally induced atherosclerosis were studied. The same indices were studied in the tissues of the myocardium, liver, and brain stem-reticular formation after decapitation of the animals at the end of the experiment. Periodic motion restriction caused an increase in blood beta-lipoproteins in the rabbits at the beginning of the experiment. An increase in general cholesterol content and a decrease in the lecithincholesterol index were established at the end of the experiment. Myocardial beta-lipoprotein and brain stem reticular formation general cholesterol contents were elevated; catecholamine content was increased at the end of the experiment. In the initial months, free adrenaline basically increased, while in later months blood adrenaline decreased and blood noradrenaline increased.

    The Wissler Human Thermal Model (WHTM) is a thermal math model of the human body that has been widely used to predict the human thermoregulatory response to a variety of cold and hot environments. The model has been shown to predict core temperature and skin temperatures higher and lower, respectively, than in tests of subjects in crew escape suit working in a controlled hot environments. Conversely the model predicts core temperature and skin temperatures lower and higher, respectively, than in tests of lightly clad subjects immersed in cold water conditions. The blood flow algorithms of the model has been investigated to allow for more and less flow, respectively, for the cold and hot case. These changes in the model have yielded better correlation of skin and core temperatures in the cold and hot cases. The algorithm for onset of shiver did not need to be modified to achieve good agreement in cold immersion simulations

    Obstructive jaundice (OJ) is a severe condition that leads to several complications. One of the important problems in OJ is the increased incidence of endotoxemia, which is the result of bacterial translocation (BT) and defective host immune response. Lipid peroxidation (LP) is an important problem in OJ and sepsis in which nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) activity are increased and antioxidative activity is decreased. Formation of peroxynitrite (ONOO(-)) anion leads to cellular damage and apoptosis. In this experimental study, we explore the effect of specific iNOS inhibitor aminoguanidine (AG) on blood and tissue (liver and renal) LP and iNOS levels in jaundiced rats with endotoxemia induced with lipopolysaccharide (LPS). Rats were randomized into six groups; group A, sham; group B, obstructive jaundice (OJ); group C, OJ + LPS; group D, OJ + AG; group E, OJ + LPS + AG; group F, OJ + AG + LPS. Serum malondialdehyde (MDA) and serum myeloperoxidase (MPO) activity and liver and renal tissue MDA, MPO, and Na(+)/K(+)-ATPase activity levels were detected in biochemical methods. Liver and renal tissue iNOS levels were examined immunohistopathologically. Serum and tissue MDA and MPO levels and tissue iNOS expression were increased significantly in groups B, C, and E, while tissue ATPase levels were decreased significantly in the same groups. In the group treated with AG (group D), serum and tissue MDA and MPO levels and tissue iNOS expression were decreased while tissue ATPase levels were increased significantly. In group F, if AG was administrated before LPS, we observed that serum and tissue MDA and MPO levels and tissue iNOS expression were decreased while tissue ATPase levels were increased significantly. Thus, our study showed that AG had a protective effect when it was administrated before LPS, but it failed to prevent tissue iNOS expression and LP if there was established endotoxemia in OJ.

    Full Text Available Moulting is a biological condition that can happen in poultry. It is resulted from the complex interaction which involves the function of thyroxine hormone. Moulting can reduce or even stop the egg production. A study was conducted to observe the moulting patterns of local ducks (Alabio and Mojosari and to determine the relation of moulting with blood lipids (triglycerides, egg production and quality. Each breed consisted of ten female dukcs were observed for moulting pattern, blood triglycerides, egg production and quality. Fourty ducks were used for simulation of egg production. Data from moulting patterns,egg production and quality were analyzed using t-based on Least Square means with Statistical Analysis System. The relation of breeds and moulting patterns with triglycerides were analyzed using Analysis of Variance (ANOVA for a completely randomized design in a factorial arrangement of 2x2. The main factor was kind of breeds, while the subfactor was the period of moulting, before and during moulting. There were not interaction in every variables between both factors. The average moulting periode of Alabio was significantly (P<0.05 shorter than that of Mojosari (69 vs 76 days. There were 40% of Alabio ducks moulting for 61-70 days, while 40% of Mojosari ducks moulting for 71-80 days. Egg production of Alabio ducks before and after moulting were higher than those Mojosari ducks. The triglycerides content of Alabio and Mojosari ducks was decreased during moulting, in Alabio ducks they were 32.02 and 27.64 μg/ml before and during moulting, while in Mojosari ducks they were 32.83 and 29.32 μg/ml respectively. Egg weight, albumin weight, yolk weight, and haugh unit of the two breeds increased after moulting, while yolk colour decreased. The average yolk colour of Alabio ducks before and after moulting were 6.90 and 5.11, while in Mojosari ducks they were 7.90 and 4.60 respectively.

    Full Text Available The study of biological processes has become increasingly reliant on obtaining high-resolution spatial and temporal data through imaging techniques. As researchers demand molecular resolution of cellular events in the context of whole organisms, correlation of non-invasive live-organism imaging with electron microscopy in complex three-dimensional samples becomes critical. The developing blood vessels of vertebrates form a highly complex network which cannot be imaged at high resolution using traditional methods. Here we show that the point of fusion between growing blood vessels of transgenic zebrafish, identified in live confocal microscopy, can subsequently be traced through the structure of the organism using Focused Ion Beam/Scanning Electron Microscopy (FIB/SEM and Serial Block Face/Scanning Electron Microscopy (SBF/SEM. The resulting data give unprecedented microanatomical detail of the zebrafish and, for the first time, allow visualization of the ultrastructure of a time-limited biological event within the context of a whole organism.

Being systemic, it might be possible to evaluate the extent of atherosclerosis from retinal vascular findings. We investigated the possible correlation between penile cavernosal artery blood flow and retinal vascular findings in patients with arteriogenic ED.Patients and methods: Sixty patients with ED were divided according to the peak systolic velocity (PSV in their penile cavernosal arteries into two groups; Group A included 30 patients with PSV less than 25 cm/sec, and Group B included 30 patients with PSV more than 35 cm/sec. Blood flow in the penile cavernosal artery was measured with color Doppler ultrasonography. All patients were assessed by ocular fundus examination under amydriatic conditions to evaluate retinal vascular atherosclerotic changes using Hyman’s classification.Results: Evidence of retinal vascular atherosclerotic changes was found in 19 patients (63.3% in Group A and in 10 patients (33.3% in Group B.Conclusions: Our study confirms the possibility of predicting penile arterial vascular status in patients with ED from their retinal vascular findings by using amydriatic simple, practical funduscopy.Keywords: erectile dysfunction, atherosclerosis, retinal vascular atherosclerosis

    Comparative study has been carried of effect of the three-day long starvation, running, and their combination on morphological parameters of rat blood, lipid metabolism, and activity of blood Na,K-ATPase. Different effect has been shown of these stress factors on the blood erythrocyte composition. Starvation is accompanied by the most pronounced release of stored erythrocyte into blood, which results in a significant decrease both of the total amount of reticulocytes and the complete absence of reticulocytes of the I stage of maturity (the youngest). The running on treadmill led to a significant increase of the total amount of blood reticulocytes and to multiple increase of immature reticulocytes (RC-I and RC-II), which can indicate some stress of the bone marrow erythroid stem line. The curve of acid resistance of blood reticulocytes has shown the animal to experience the greatest stress at a combination of starvation and running. Starvation and running produced different effects on blood lipid characteristics. The content of triacylglycerides (TAG) in blood rose by 40% at starvation and decreased by 30% at running, a similar tendency being found for index of atherogeneity. The fatty acid composition of blood phospholipids at running and its combination with starvation practically did not differ from control. A change of Na,K-ATPase, which is so characteristic of reaction to various kinds of stress, sharply fell at starvation (by 22%), but increased at running (by 13%) and decreased markedly at combination of these actions. Absorption spectra of lipid extracts of the whole blood of the rats submitted to various stress actions showed that extracted from blood (at different amount depending on the kind of action) is an organic substance with coupled bonds, which absorbs light in the diapason of 360-620 nm. The absorption of light in the diapason of 400-410 nm has been found to belong to the Soret band of ferroheme and ferriheme. The shift of the Soret band indicates

    Background— Genome-wide association studies have identified loci influencing circulating lipid concentrations in humans; further information on novel contributing genes, pathways, and biology may be gained through studies of epigenetic modifications. Methods and Results— To identify epigenetic changes associated with lipid concentrations, we assayed genome-wide DNA methylation at cytosine–guanine dinucleotides (CpGs) in whole blood from 2306 individuals from 2 population-based cohorts, with replication of findings in 2025 additional individuals. We identified 193 CpGs associated with lipid levels in the discovery stage (P<1.08E-07) and replicated 33 (at Bonferroni-corrected P<0.05), including 25 novel CpGs not previously associated with lipids. Genes at lipid-associated CpGs were enriched in lipid and amino acid metabolism processes. A differentially methylated locus associated with triglycerides and high-density lipoprotein cholesterol (HDL-C; cg27243685; P=8.1E-26 and 9.3E-19) was associated with cis-expression of a reverse cholesterol transporter (ABCG1; P=7.2E-28) and incident cardiovascular disease events (hazard ratio per SD increment, 1.38; 95% confidence interval, 1.15–1.66; P=0.0007). We found significant cis-methylation quantitative trait loci at 64% of the 193 CpGs with an enrichment of signals from genome-wide association studies of lipid levels (PTC=0.004, PHDL-C=0.008 and Ptriglycerides=0.00003) and coronary heart disease (P=0.0007). For example, genome-wide significant variants associated with low-density lipoprotein cholesterol and coronary heart disease at APOB were cis-methylation quantitative trait loci for a low-density lipoprotein cholesterol–related differentially methylated locus. Conclusions— We report novel associations of DNA methylation with lipid levels, describe epigenetic mechanisms related to previous genome-wide association studies discoveries, and provide evidence implicating epigenetic regulation of reverse cholesterol

    2000-01-01

    Full Text Available The aim of this study was to analyze the thickness of the intima-media complex (IMC using a noninvasive method. The carotid and femoral common arteries were evaluated by noninvasive B-mode ultrasound in 63 normotensive and in 52 hypertensive subjects and the thickness of the IMC was tested for correlation with blood pressure, cardiac structures and several clinical and biological parameters. The IMC was thicker in hypertensive than in normotensive subjects (0.67 ± 0.13 and 0.62 ± 0.16 vs 0.54 ± 0.09 and 0.52 ± 0.11 mm, respectively, P<0.0001. In normotensive patients, the simple linear regression showed significant correlations between IMC and age, body mass index and 24-h systolic blood pressure for both the carotid and femoral arteries. In hypertensives the carotid IMC was correlated with age and 24-h systolic blood pressure while femoral IMC was correlated only with 24-h diastolic blood pressure. Forward stepwise regression showed that age, body mass index and 24-h systolic blood pressure influenced the carotid IMC relationship (r2 = 0.39 in normotensives. On the other hand, the femoral IMC relationship was influenced by 24-h systolic blood pressure and age (r2 = 0.40. In hypertensives, age and 24-h systolic blood pressure were the most important determinants of carotid IMC (r2 = 0.37, while femoral IMC was influenced only by 24-h diastolic blood pressure (r2 = 0.10. There was an association between carotid IMC and echocardiographic findings in normotensives, while in hypertensives only the left posterior wall and interventricular septum were associated with femoral IMC. We conclude that age and blood pressure influence the intima-media thickness, while echocardiographic changes are associated with the IMC.

    Full Text Available Plasma amyloid beta (Aβ levels are being investigated as potential biomarkers for Alzheimer's disease. In AB128 cross-sectional study, a number of medical relevant correlates of blood Aβ40 or Aβ42 were analyzed in 140 subjects (51 Alzheimer's disease patients, 53 healthy controls and 36 individuals diagnosed with mild cognitive impairment. We determined the association between multiple variables with Aβ40 and Aβ42 levels measured in three different blood compartments called i Aβ directly accessible (DA in the plasma, ii Aβ recovered from the plasma matrix (RP after diluting the plasma sample in a formulated buffer, and iii associated with the remaining cellular pellet (CP. We confirmed that diastolic blood pressure (DBP is consistently correlated with blood DA Aβ40 levels (r=-0.19, P=0.032. These results were consistent in the three phenotypic groups studied. Importantly, the observation resisted covariation with age, gender or creatinine levels. Observed effect size and direction of Aβ40 levels/DBP correlation are in accordance with previous reports. Of note, DA Aβ40 and the RP Aβ40 were also strongly associated with creatinine levels (r=0.599, P<<0.001 and to a lesser extent to urea, age, hematocrit, uric acid and homocysteine (p<0.001. DBP and the rest of statistical significant correlates identified should be considered as potential confounder factors in studies investigating blood Aβ levels as potential AD biomarker. Remarkably, the factors affecting Aβ levels in plasma (DA, RP and blood cell compartments (CP seem completely different.

    1999-10-01

    The cerebral circulation and metabolism of ten preoperative cardiac surgery patients were assessed. Alterations in regional cerebral blood flow (rCBF), measured by 123I-N- isopropyl-p-iodo-amphetamine single-photon emission computed tomography, and in cerebral oxygen metabolism, simultaneously detected by near-infrared spectroscopy (NIRS) before and after acetazolamide administration, were investigated. The rCBF (ml/min/100 g) increased significantly from 40.21 +/- 7.65 to 56.24 +/- 13.69 (p equals 0.001), and a significant increase in oxyhemoglobin (Oxy-Hb) of 13.9% (p equals 0.0022) and total hemoglobin (Total-Hb) of 5.7% (0.0047) along with a significant decrease in deoxyhemoglobin (Deoxy-Hb) of 8.9% (p equals 0.0414) were observed concomitantly. Thus, the Oxy-Hb/Total- Hb ratio (%Oxy-Hb) rose significantly from 67.26 +/- 9.82% to 72.98 +/- 8.09% (p equals 0.0022). Examination of the relationships between individual parameters showed that the percentage changes in rCBF and Oxy-Hb were significantly correlated (r equals 0.758, p equals 0.011). The percentage changes in rCBF and %Oxy-Hb were also correlated significantly (r equals 0.740, p equals 0.014). In conclusion, this evidence suggested that NIRS is able to detect relative changes in cerebral hemodynamics and reflect luxury perfusion induced by acetazolamide.

    Full Text Available The goals of the present study were to evaluate the kinetics of blood parasitism by examination of fresh blood, blood culture (BC and PCR assays and their correlation with heart parasitism during two years of infection in Beagle dogs inoculated with the Be-78, Y and ABC Trypanosoma cruzi strains. Our results showed that the parasite or its kDNA is easily detected during the acute phase in all infected animals. On the other hand, a reduced number of positive tests were verified during the chronic phase of the infection. The frequency of positive tests was correlated with T. cruzi strain. The percentage of positive BC and blood PCR performed in samples from animals inoculated with Be-78 and ABC strains were similar and significantly larger in relation to animals infected with the Y strain.Comparison of the positivity of PCR tests performed using blood and heart tissue samples obtained two years after infection showed two different patterns associated with the inoculated T. cruzi strain: (1 high PCR positivity for both blood and tissue was observed in animals infected with Be-78 or ABC strains; (2 lower and higher PCR positivity for the blood and tissue, respectively, was detected in animals infected with Y strains. These data suggest that the sensitivity of BC and blood PCR was T. cruzi strain dependent and, in contrast, the heart tissue PCR revealed higher sensitivity regardless of the parasite stock.

    The objective of the study was to evaluate the effect of inulin or dandelion, chicory and Jerusalem artichoke powder on lipid indices and fatty acid profile in fattener tissues. The experiment involved 120 crossbred pigs (PL x PLW) x Duroc with an initial body weight of 25.0 +/- 0.5 kg. Animals were assigned into 6 groups. A diet for group I (control) did not comprise an inulin additive, group II and III received 2% inulin (water or water-alcohol extraction of inulin from chicory root, respectively), while the mixtures for group IV, V and VI contained 4% root powder from Jerusalem artichoke (topinambur), chicory or dandelion, respectively. The animals were slaughtered at 115 kg body weight. The samples of blood, liver and the muscle longissimus dorsi tissues as well as whole hearts were collected for analysis. Fatty acid profile, some lipid indices and crude fat and cholesterol content were evaluated. Dietary supplement of 40 g dandelion powder resulted in preferable significant changes in the blood lipid indices and fatty acids composition (increased PUFA share and decreased n-6/n-3 ratio).

  16. Cord blood glutathione depletion in preterm infants: correlation with maternal cysteine depletion.

    Directory of Open Access Journals (Sweden)

    Alice Küster

    Full Text Available BACKGROUND: Depletion of blood glutathione (GSH, a key antioxidant, is known to occur in preterm infants. OBJECTIVE: Our aim was to determine: 1 whether GSH depletion is present at the time of birth; and 2 whether it is associated with insufficient availability of cysteine (cys, the limiting GSH precursor, or a decreased capacity to synthesize GSH. METHODOLOGY: Sixteen mothers delivering very low birth weight infants (VLBW, and 16 mothers delivering healthy, full term neonates were enrolled. Immediately after birth, erythrocytes from umbilical vein, umbilical artery, and maternal blood were obtained to assess GSH [GSH] and cysteine [cys] concentrations, and the GSH synthesis rate was determined from the incorporation of labeled cysteine into GSH in isolated erythrocytes ex vivo, measured using gas chromatography mass spectrometry. PRINCIPAL FINDINGS: Compared with mothers delivering at full term, mothers delivering prematurely had markedly lower erythrocyte [GSH] and [cys] and these were significantly depressed in VLBW infants, compared with term neonates. A strong correlation was found between maternal and fetal GSH and cysteine levels. The capacity to synthesize GSH was as high in VLBW as in term infants. CONCLUSION: The current data demonstrate that: 1 GSH depletion is present at the time of birth in VLBW infants; 2 As VLBW neonates possess a fully active capacity to synthesize glutathione, the depletion may arise from inadequate cysteine availability, potentially due to maternal depletion. Further studies would be needed to determine whether maternal-fetal cysteine transfer is decreased in preterm infants, and, if so, whether cysteine supplementation of mothers at risk of delivering prematurely would strengthen antioxidant defense in preterm neonates.

    Full Text Available Epidemiological and experimental data point to involvement of oxygen derived radicals in the pathogenesis of gynecological disorders, as well as in cancer development. The objective of the present study was to examine changes in activities and levels of copper/zinc superoxide dismutase (CuZnSOD and lipid hydroperoxides (LOOH in blood and endometrial tissue of patients diagnosed with uterine myoma, endometrial polypus, hyperplasia simplex, hyperplasia complex and adenocarcinoma endometrii. The results of our study have shown decreased SOD activities and unchanged SOD protein level in blood of all examined patients in comparison to healthy subjects. Decrease of both SOD activity and level was found in endometrium of patients with hyperplasia simplex, hyperplasia complex and adenocarcinoma in comparison to women with polypus or myoma. LOOH level was elevated in both tissues of patients with hyperplasiaor adenocarcinoma in comparison to healthy subjects or patients with benign diagnosis. Our findings suggest that the decrease in SOD activity and level, as well as the increase in LOOH level, in patients with gynecological disorders, render these patients more susceptible to oxidative damage caused by reactive oxygen species (ROS. An imbalance in ROS formation and SOD level may be important in the pathogenesis and/or perpetuation of tissue damage in gynecological patients. Since evidence suggests that SOD may be a therapy target for cancer treatment, our findings provide a basis for further research and options for clinical applications.Resultados epidemiológicos e experimentais apontam para o envolvimento dos radicais derivados do oxigênio na patogênese das moléstias ginecológicas, assim como no desenvolvimento do câncer.

    Cell-penetrating and antimicrobial peptides show a remarkable ability to translocate across physiological membranes. Along with factors such as electric-potential-induced perturbations of membrane structure and surface tension effects, experiments invoke porelike membrane configurations during the solute transfer process into vesicles and cells. The initiation and formation of pores are associated with a nontrivial free-energy cost, thus necessitating a consideration of the factors associated with pore formation and the attendant free energies. Because of experimental and modeling challenges related to the long time scales of the translocation process, we use umbrella sampling molecular dynamics simulations with a lipid-density-based order parameter to investigate membrane-pore-formation free energy employing Martini coarse-grained models. We investigate structure and thermodynamic features of the pore in 18 lipids spanning a range of headgroups, charge states, acyl chain lengths, and saturation. We probe the dependence of pore-formation barriers on the area per lipid, lipid bilayer thickness, and membrane bending rigidities in three different lipid classes. The pore-formation free energy in pure bilayers and peptide translocating scenarios are significantly coupled with bilayer thickness. Thicker bilayers require more reversible work to create pores. The pore-formation free energy is higher in peptide-lipid systems than in peptide-free lipid systems due to penalties to maintain the solvation of charged hydrophilic solutes within the membrane environment.

    We previously measured for healthy subjects and patients who require hemodialysis the complex relative permittivity (εr´-jεr´´) of whole blood, and found that εr´-axis intercept εrt´ of straight line approximation to the Cole-Cole plots at frequencies from 200 MHz to 1GHz is significantly different with a level of less than 1% among its averaged values for healthy subjects and patients before and after dialysis, though any correlations between εrt´ and blood urea nitrogen (BUN) and creatinine being used as main indices for hemodialysis evaluation have not so far been clarified. In this study, to make correlation analyses between the intercept εrt´ and blood biochemical components for nine patients before and after hemodialysis, we measured six kinds of their blood components including BUN and creatinine, and calculated their Pearson product-moment correlation coefficients for εrt´ along with significant probability P based on a t-test. It should be noted that P is a reference probability to determine whether or not a null hypothesis can be rejected, and that the P value of 0.05 is commonly used as a significance level for statistical test. As a result, we found that a strong correlation with P 0.05 between εrt´ and other blood components including BUN and creatinine. Although albumin is not used as an index for hemodialysis efficiency, it can reflect water amount in blood vessels and liver operation. This finding implies that εrt´ could be used as an index for evaluating blood viscosity and liver function.

    Full Text Available Abstract Background There is increasing evidence indicating that genes involved in certain metabolic processes of cardiovascular diseases may be of particular influence in people with low body weight at birth. We examined whether the apolipoprotein (APO E, APOC3 and the peroxisome proliferator-activated receptor-γ-2 (PPARγ2 polymorphisms influence the association between low birth weight and blood lipid levels in healthy adolescents aged 13–18.5 years. Methods A cross-sectional study of 502 Spanish adolescents born at term was conducted. Total (TC and high density lipoprotein cholesterol (HDLc, triglycerides (TG, apolipoprotein (apo A and B, and lipoprotein(a [Lp(a] were measured. Low density lipoprotein cholesterol (LDLc, TC-HDLc, TC/HDLc and apoB/apoA were calculated. Results Low birth weight was associated with higher levels of TC, LDLc, apoB, Lp(a, TC-HDLc, TC/HDLc and apoB/apoA in males with the APOE ε3ε4 genotype, whereas in females, it was associated with lower HDLc and higher TG levels. In males with the APOC3 S1/S2 genotype, low birth weight was associated with lower apoA and higher Lp(a, yet this association was not observed in females. There were no associations between low birth weight and blood lipids in any of the PPARγ2 genotypes. Conclusion The results indicate that low birth weight has a deleterious influence on lipid profile particularly in adolescents with the APOE ε3/ε4 genotype. These findings suggest that intrauterine environment interact with the genetic background affecting the lipid profile in later life.

BPs were recorded simultaneously in the same arm. Systolic BP (SBP), analyzed in 1,440 readings, was 127.5 +/- 18.9 mm Hg by A system and 127.6 +/- 18.6 mm Hg by M system (NS). Diastolic BP (DBP) was 71.3 +/- 11.7 mm Hg by A and 79.3 +/- 11 mm Hg by M (p less than 0.001). We confirmed good correlations in SBP and DBP measured by both methods (r = 0.95 and r = 0.88, respectively; both p less than 0.001). Nearly complete consistency was noted between SBP readings by both methods but not between DBP readings; the readings by M were significantly higher than those by A. Since A's consistency with SBP and DBP readings obtained by the intra-arterial method (the most commonly used method) previously had been proven to be satisfactory, DBP obtained by clinical practice is possibly overestimated in adults.

    AIMS: To assess the effects of weight gain on metabolic control, plasma lipids and blood pressure in patients with Type 1 diabetes. METHODS: Patients in the EURODIAB Prospective Complications Study (n = 3250) were examined at baseline and 1800 (55%) were re-examined a mean of 7.3 years later. Patients had Type 1 diabetes, defined as a diagnosis made before age 36 years and with a need for continuous insulin therapy within a year of diagnosis. Patients were aged 15-60 years at baseline and were stratified for age, sex and duration of diabetes. RESULTS: The change in HbA(1c) from baseline to follow-up examination was significantly more favourable in those who gained 5 kg or more during follow-up (\\'marked weight gain\\') than in patients who gained less or no weight or lost weight (\\'less or no weight gain\\'). In those with marked weight gain, there was a significantly greater rise in plasma triglycerides and total cholesterol and significantly less favourable changes in low-density lipoprotein and high-density lipoprotein cholesterol compared with those with less or no weight gain, with or without adjustment for HbA(1c). Systolic and diastolic blood pressure also rose significantly more in the group with marked weight gain. CONCLUSION: Weight gain in patients with Type 1 diabetes has adverse effects on plasma lipids and blood pressure, despite a small improvement in glycaemic control.

    Objective: To investigate the ability of the methanolic extract of pineapple peel to modulate alcohol-induced lipid peroxidation, changes in catalase activities and hepatic biochemical marker levels in blood plasma. Methods: Oxidative stress was induced by oral administration of ethanol (20% w/v) at a dosage of 5 mL/kg bw in rats. After 28 days of treatment, the rats were fasted overnight and sacrificed by cervical dislocation. Blood was collected with a 2 mL syringe by cardiac puncture and was centrifuged at 3000 rpm for 10 min. The plasma was analyzed to evaluate malondialdehyde (MDA), catalase activity, aspartate aminotransferase (AST), alkaline phosphatase (ALP) and alanine aminotransferase (ALT) concentrations. Results: Administration of alcohol caused a drastic increase (87.74%) in MDA level compared with the control. Pineapple peel extract significantly reduced the MDA level by 60.16% at 2.5 mL/kg bw. Rats fed alcohol only had the highest catalase activity, treatment with pineapple peel extract at 2.5 mL/kg bw however, reduced the activity. Increased AST, ALP and ALT activities were observed in rats fed alcohol only respectively, treatment with pineapple peel extract drastically reduced their activities. Conclusions: The positive modulation of lipid peroxidation, catalase activities as well as hepatic biomarker levels of blood plasma by the methanolic extract of pineapple peels under alcohol-induced oxidative stress is an indication of its protective ability in the management of alcohol-induced toxicity.

    Full Text Available Vitamin D deficiency is a major health problem in the Saudi population. A negative association between blood pressure and vitamin D level has been suggested in several clinical and epidemiological studies and evidence for an effect of vitamin D in lowering blood pressure was reported. These findings indicate that 1,25(OH2D3 deficiency may play a role in the pathogenesis of hypertension through its effect on the renin-angiotensin system. We are the first to investigate the correlation between blood pressure or renin concentration and vitamin D status in the Saudi population METHODS: we included 201 healthy Saudi premenopausal females (20-45 years old. Blood pressure was measured by a standardized method using an automated blood pressure monitor (BPTru. Fasting blood samples were collected from each participant after 20 minutes of rest in the seated position. Serum cholicalciferol, PTH and renin concentration were measured by sandwich chemiluminescence immunoassaymethod (DiaSorin, Italy. RESULTS: The analysis included 192 subjects who were normotensive (blood pressure <140/90 mmHg.  A total of  34% of women had a severe deficiency (vitamin D ≤ 12.5 nmol/L; 41% had moderate deficiency (vitamin D levels between 12.5 - 25 nmol/L;  23% had mild deficiency (vitamin D level ≥ 25 - < 50 nmol/L; and 2% had insufficiency (vitamin D level  ≥ 50 - ≤ 75 nmol/L. None had a sufficient level of ≥75 nmol/L.  The systolic blood pressure ranged from 79-130.5mmHg and the diastolic from 48.5-85.5 mmHg.  Both systolic and diastolic blood pressures were significantly higher in women that were in the lower 2 quartiles of vitamin D.  However, linear regression analysis adjusting for potential confounders showed that 25(OHD level was not a predictor of either systolic or diastolic blood pressures.  A negative correlation (although not significant was found between vitamin D level and plasma renin concentration in this study group. CONCLUSION: Vitamin D

    Full Text Available Fifty-seven type 2 diabetic patients with metabolic syndrome and on insulin were assessed by a paired analysis before and 6 months after addition of metformin as combination therapy to evaluate the impact of the association on glycemic control, blood pressure, and lipid profile. This was a historical cohort study in which the files of type 2 diabetic patients with metabolic syndrome on insulin were reviewed. The body mass index (BMI, waist circumference, lipid profile, A1C level, fasting blood glucose level, daily dose of NPH insulin, systolic blood pressure, and diastolic blood pressure were assessed in each patient before the start of metformin and 6 months after the initiation of combination therapy. Glycemic control significantly improved (P < 0.001 after the addition of metformin (1404.4 ± 565.5 mg/day, with 14% of the 57 patients reaching A1C levels up to 7%, and 53% reaching values up to 8%. There was a statistically significant reduction (P < 0.05 of total cholesterol (229.0 ± 29.5 to 214.2 ± 25.0 mg/dL, BMI (30.7 ± 5.4 to 29.0 ± 4.0 kg/m², waist circumference (124.6 ± 11.7 to 117.3 ± 9.3 cm, and daily necessity of insulin. The reduction of total cholesterol occurred independently of the reductions of A1C (9.65 ± 1.03 to 8.18 ± 1.01% and BMI and the reduction of BMI and WC did not interfere with the improvement of A1C. In conclusion, our study showed the efficacy of the administration of metformin and insulin simultaneously without negative effects. No changes were detected in HDL-cholesterol or blood pressure.

    Older and even new antidepressants cause adverse effects, such as orthostatic hypotension, hyper- or hypoglycemia, liver injury or lipid disorders. In our previous experiments we showed significant antidepressant- and anxiolytic-like activities of dual 5-HT1A and 5-HT7 antagonists with α1-adrenolitic properties i.e. 1-[(2,6-dimethylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-14) and 1-[(2-chloro-6-methylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-15). Here, we evaluated the influence of chronic administration of HBK-14 and HBK-15 on blood pressure (non-invasive blood pressure measurement system for rodents), lipid profile (total cholesterol, low density lipoproteins—LDL, high density lipoproteins—HDL, triglycerides), glucose level, and liver enzymes activity (aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transferase). We determined potential antihistaminic (isolated guinea pig ileum) and antioxidant properties (ferric reducing ability of plasma–FRAP, non-protein thiols–NPSH, stable free radical diphenylpicrylhydrazyl—DPPH) cytotoxicity. Our experiments revealed that HBK-14 and HBK-15 did not influence blood pressure, lipid profile, glucose level or liver enzymes activity in rats after 2-week treatment. We also showed that none of the compounds possessed antioxidant or cytotoxic properties at antidepressant- and anxiolytic-like doses. HBK-14 and HBK-15 very weakly blocked H1 receptors in guinea pig ileum. Positive results of our preliminary experiments on the safety of HBK-14 and HBK-15 encourage further studies concerning their effectiveness in the treatment of depression and/or anxiety disorders.

    BACKGROUND AND PURPOSE: Delayed cerebral ischemia (DCI) is a serious and frequent complication following subarachnoid hemorrhage. Treatments with convincing effect are lacking and the pathophysiology behind DCI remains poorly understood. Neuropeptide Y (NPY) is a potent endogenous vasoconstrictor...... and a role of NPY in the development of DCI has been proposed. This study investigated the relationship between plasma-NPY and cerebral blood flow (CBF), cerebral vasospasm, DCI, and clinical outcome. METHODS: In 90 patients with subarachnoid hemorrhage, NPY was measured in peripheral blood days 2 to 11. Any...... occurrence of DCI was recorded and CBF was quantified day 3 and day 8 using computed tomography (CT) perfusion. CT angiography was performed day 8. Clinical outcome was assessed after 3 months. RESULTS: No correlation was found between plasma-NPY and CBF or angiographic vasospasm. The correlation between...

TC, TG, and HDL-C content in rats were measured before the experiments. All rats were divided into four groups randomly according to their TC levels: high blood lipids group and three dose groups (5 times, 10 times and 30 times feeding quantity of tartary buckwheat wine respectively). All dose groups were administered with tartary buckwheat wine for 30 d, then after 16 h fasting, TC, TG, and HDL-C content in rats were measured. The results showed that TG content in rats in dose groups of 10 times and 30 times feeding quantity of tartary buckwheat wine was evidently lower than that in contrast group, TC content in rats in dose group of 30 times feeding quantity of tartary buckwheat wine was evidently lower than that in high blood lipids group and other two dose groups, which proved that drinking tartary buckwheat wine is helpful for reducing blood lipids.

    The effectiveness of several non-lethal techniques as indicators of total lipid content in smallmouth bass Micropterus dolomieu, walleye Sander vitreus and channel catfish Ictalurus punctatus was investigated. The techniques included (1) the Fulton and relative condition factors, (2) relative mass, (3) plasma indicators of nutritional status (alkaline phosphatase, calcium, cholesterol, protein, triglycerides and glucose) and (4) readings from a hand-held, microwave energy meter. Although simple linear regression analysis showed that lipid content was significantly correlated with several predictor variables in each species, the r2 values for the relations ranged from 0·17 to 0·50 and no single approach was consistent for all species. Only one model, between energy-meter readings and lipid content in I. punctatus, had an r2 value (0·83) high enough to justify using it as a predictive tool. Results indicate that no single variable was an accurate and reliable indicator of whole body lipid content in these fishes, except the energy meter for I. punctatus.

    In obstructive jaundice, free radical production is increased and antioxidative activity is reduced. N-Acetylcysteine (NAC) has a beneficial effect with anti-inflammatory and antioxidant activity, acting as a free radical scavenger. NAC inhibits inducible nitric oxide synthase, suppresses cytokine expression/release, and inhibits adhesion molecule expression and nuclear factor kappa B. The aim of this study was to investigate the effects of NAC on liver/renal tissue and serum lipid peroxidation in lipopolysaccharide (LPS)-induced obstructive jaundice. We randomized 60 rats into 6 groups: group 1, Sham; group 2, obstructive jaundice (OJ) induced after bile-duct ligation; group 3, OJ + NAC (100 mg kg- 1 subcutaneously); group 4, OJ + LPS (10 mg kg-1); group 5, OJ + NAC + LPS; and group 6, OJ + LPS + NAC. For each group, the biochemical markers of lipid peroxidation and the antioxidant products were measured in serum and liver/renal tissue after sacrifice. Almost all lipid peroxidation products levels were increased and antioxidant products levels were decreased in groups who received LPS (groups 4, 5, and 6), but the effect was less remarkable when NAC was administered before LPS (group 5). The same trend was seen for groups with OJ +/- LPS who did not received NAC or received it after induced toxemia (groups 2, 4, and 6) as compared to groups 1 and 3. Moreover, in the case of OJ + LPS, rats treated with NAC before LPS (group 5) had lower lipid peroxidation products levels and higher antioxidant products levels as compared to those who did not received NAC (group 4). This phenomenon was not reproducible with NAC administered after LPS (group 6). Thus, results of this study showed that NAC prevents the deleterious effects of LPS in obstructive jaundice by reducing lipid peroxidation in serum and liver/renal tissue if administered before LPS. Nonetheless, NAC failed to prevent the lipid peroxidation in the case of established endotoxemia in obstructive jaundice.

    Full Text Available Vascular infiltration and associated alterations in microvascular blood flow are critical for complete bone graft healing. Therefore, real-time, longitudinal measurement of blood flow has the potential to successfully predict graft healing outcomes. Herein, we non-invasively measure longitudinal blood flow changes in bone autografts and allografts using diffuse correlation spectroscopy in a murine femoral segmental defect model. Blood flow was measured at several positions proximal and distal to the graft site before implantation and every week post-implantation for a total of 9 weeks (autograft n = 7 and allograft n = 10. Measurements of the ipsilateral leg with the graft were compared with those of the intact contralateral control leg. Both autografts and allografts exhibited an initial increase in blood flow followed by a gradual return to baseline levels. Blood flow elevation lasted up to 2 weeks in autografts, but this duration varied from 2 to 6 weeks in allografts depending on the spatial location of the measurement. Intact contralateral control leg blood flow remained at baseline levels throughout the 9 weeks in the autograft group; however, in the allograft group, blood flow followed a similar trend to the graft leg. Blood flow difference between the graft and contralateral legs (ΔrBF, a parameter defined to estimate graft-specific changes, was elevated at 1-2 weeks for the autograft group, and at 2-4 weeks for the allograft group at the proximal and the central locations. However, distal to the graft, the allograft group exhibited significantly greater ΔrBF than the autograft group at 3 weeks post-surgery (p < 0.05. These spatial and temporal differences in blood flow supports established trends of delayed healing in allografts versus autografts.

    Background: Studies have demonstrated the effect of different dietary fats on blood pressure (BP) in general population. However, these associations have not yet been described in people with spinal cord injury (SCI). Methods: Referred patients to Brain and SCI Research Center between 2011 and 2014 have been invited to participate. Only paraplegic individuals were recruited and patients with injury at cervical or higher thoracic sections were excluded to omit the bias effect of autonomic dysreflexia. Dietary intakes were assessed by recording consumed foods by 24-hour dietary recall interviews using Nutritionist IV 3.5.3 modified for Iranian foods. Systolic BP (SBP) and diastolic BP (DBP) were measured 3 times and the mean values entered analysis. Results: Higher intakes of cholesterol were related to higher BP (P = 0.010 and 0.011 for SBP and DBP, respectively). Similarly, intake of saturated fat was positively correlated to both SBP (P = 0.016, r = 0.21) and DBP (P = 0.011, r = 0.22). The effect of eicosapentaenoic acid (EPA) on BP was insignificant (P = 0.760 and 0.720 for SBP and DBP, respectively). However, intake of docosahexaenoic acid (DHA) was related to lower BP among people with SCI. Conclusion: This study has demonstrated that higher intakes of cholesterol and saturated fat are associated with increased BP, whereas DHA is an antihypertensive agent. Dietary modifications with reduction of cholesterol and saturated fat along with intake of additional DHA supplements may help to reduce BP in spinal cord injured-individuals with hypertension.

    This study has been conducted in order to study the possible correlations between the nutritional value of plants selected by camels during the dry and green season and the corresponding blood and milk composition of the dromedary camels. The study has been conducted on 50 indigenous Arabian camels of different age and kept under natural range in Southern Darfur. The dromedary camels selected plants with significantly (p<0.05) higher crude protein content during the dry season and kept the serum albumin concentration and milk protein content at the same levels as those observed during the green season. However, the significantly (p<0.05) higher lipogenic content (ether extract + crude fiber) of the plant selected during the dry season resulted in significantly (p<0.05) higher serum triacylglycerides concentration and significantly (p<0.05) higher milk fat content compared to that of the green season. Although, the camels selected plants with significantly (p<0.05) higher nitrogen free extract content during the dry season, the plasma glucose level and the milk lactose content were significantly (p<0.05) reduced compared to that of the green season. The significantly (p<0.05) lower ach content of the plants selected during the dry season resulted in significantly lower serum calcium + phosphorus concentration, but did not reflect on the ash content of the milk. The results indicate that despite camels selectivity and unique adaptation to arid conditions, the milk lactose-and fat content were affected by the nutritional scarcity during the dry season. Therefore, it could be beneficial to provide energy-rich feed supplemented with calcium and phosphorus to camels kept under dry tropical conditions.

    Ambulatory blood pressure (BP) recording was performed in 57 untreated hypertensive patients by means of the "Spacelabs" non-invasive apparatus. Patients were divided into two groups according to BP measurements previously made during medical consultation. Group I comprised 25 "permanently hypertensive" patients (diastolic BP always above 95 mmHg) and group II, 32 "occasionally hypertensive" patients (diastolic BP sometimes normal, sometimes above 95 mmHg). The same circadian rhythm was observed in both groups. The mean ambulatory BP level was significantly higher (p less than 0.001) in group I patients than in group II patients, either over the whole of the 24-hour period (142.0/88.0 versus 122.7/75.3 mmHg), or in day time (149.0/92.5 versus 128.2/78.9 mmHg) or at night (128.0/80.1 versus 111.5/68.0 mmHg). In contrast, there did not seem to be any significant difference between the two groups in relative long-term variability of BP, expressed as the standard deviation/mean BP values ratio. Comparison with clinical data showed that BP values measured during consultation (160/103 mmHg in group I, 143/94 mmHg in group II) were higher than ambulatory values and, chiefly, that there was very poor correlation between the two measurement methods, precluding any extrapolation. Automatic ambulatory BP recording provides for more accurate evaluation of hypertensive patients, enabling emotional "artefacts" to be excluded and patients "reactivity" to their socio-professional environment to be assessed. However, in the absence of sufficient epidemiological data, doctors should not feel authorized to base their therapeutic decisions on the sole data supplied by ambulatory BP recordings.

    Many epidemiologic studies of environmental exposures and disease susceptibility measure DNA methylation in white blood cells (WBC). Some studies are also starting to use saliva DNA as it is usually more readily available in large epidemiologic studies. However, little is known about the correlation of methylation between WBC and saliva DNA. We examined DNA methylation in three repetitive elements, Sat2, Alu, and LINE-1, and in four CpG sites, including AHRR (cg23576855, cg05575921), cg05951221 at 2q37.1, and cg11924019 at CYP1A1, in 57 girls aged 6-15 years with blood and saliva collected on the same day. We measured all DNA methylation markers by bisulfite-pyrosequencing, except for Sat2 and Alu, which were measured by the MethyLight assay. Methylation levels measured in saliva DNA were lower than those in WBC DNA, with differences ranging from 2.8% for Alu to 14.1% for cg05575921. Methylation levels for the three repetitive elements measured in saliva DNA were all positively correlated with those in WBC DNA. However, there was a wide range in the Spearman correlations, with the smallest correlation found for Alu (0.24) and the strongest correlation found for LINE-1 (0.73). Spearman correlations for cg05575921, cg05951221, and cg11924019 were 0.33, 0.42, and 0.79, respectively. If these findings are replicated in larger studies, they suggest that, for selected methylation markers (e.g., LINE-1), methylation levels may be highly correlated between blood and saliva, while for others methylation markers, the levels may be more tissue specific. Thus, in studies that differ by DNA source, each interrogated site should be separately examined in order to evaluate the correlation in DNA methylation levels across DNA sources.

LIE groups were given group raised with normal diet was established. Blood was taken out to determine the levers of serum lipids, GSH-Px, SOD and MDA.Absolute and relative liver weight to body and MDA levels in liver were also determined at the last day. The results showed that LIE produced significant decrease of serum triglyceride total cholesterol and LDL-cholesterol levels( P < 0.01), and remarkable increase of serum HDL-cholesterol levels( P < 0.01)in experimental hyperlipidemia rats. GSH-Px and SOD activities in LIE groups were much higher than those of induced group. Meanwhile,the MDA levels in blood and liver of LIE groups were much lower than those of induced group. In LIE groups,absolute and relative liver weights were reduced comparing with hyperlipidemia-induced group without LIE.

    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 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.

    A multicenter study of blood cholesterol screening was performed in several typical environments, such as community sites (shopping malls and a supermarket), health care sites, work sites, a blood bank and a school. Cholesterol was measured with a portable, dry-chemistry analyzer using capillary blood obtained by fingerstick. Data are reported from a total of 13,824 participants, spanning the entire age spectrum. Overall, 25% of screened subjects had blood cholesterol levels above the age-specific cutpoints used in the current study. Although in the aggregate this screening experience very closely approximates the expected level of referrals, the proportion of referred screened subjects differed significantly among the 5 types of screening environments and by gender. Follow-up telephone interviews indicated that 53% of referrals had initiated a physician contact. More than 75% of those who had seen a physician reported that the diagnosis of hypercholesterolemia had been confirmed, and almost 72% had been prescribed a diet. A large proportion of referred screened subjects reported having modified their diet, particularly when recommended to do so by a physician. This study has yielded encouraging evidence that physicians gave referred screened subjects appropriate initial advice for managing hypercholesterolemia. The new technology for blood cholesterol measurement evaluated in the current study has proven to be a feasible and reliable means for measuring blood cholesterol in typical screening settings.

    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.

    Full Text Available The effects of supplemental dietary creatine and a botanical extract consisting of ginseng and astragalus were evaluated in 44 adults aged 55-84 years participating in a 12-week strength-training program. Participants consumed creatine only (Cr, creatine plus botanical extract (CrBE, or placebo (PL, and performed bench press, lat pull down, biceps curl, leg press, knee extension, and knee flexion for 3 sets of 8-12 reps on 3 days per week for 12 weeks. The 1-repetition maximum for each exercise, body composition (full-body DEXA, blood lipids, and mood states were evaluated before and after the intervention. Training improved (p < 0.05 strength and lean mass for all groups, however greater gains were observed with Cr and CrBE compared with placebo (but no difference was found between Cr and CrBE. Only CrBE improved blood lipids and self-reported vigor, and the CrBE group lost significantly more body fat and gained more bench press strength than Cr. These results indicate that strength and lean mass gains achieved by older adults participating in a strength training program can be enhanced with creatine supplementation, and that ginseng and astragalus may provide additional health and psychological benefits. However, these herbs do not appear to have an additive effect on strength and lean mass gains during training

All of them were investigated about the age, diabetes pathogenesis, exercise, diet, smoking, lipid-lowering drugs used and checked with TG, TC, HDL-C, LDL-C and so on. The difference of TG, TC, HDL-C, LDL-C among these four groups was compared by the methods of covariance analysis, regression analysis and partial correlation to evalu-ate the relationships of smoking with blood lipid. Results TG of heavy smokers was higher than the non-smokers and HDL-C was lower after correcting the effects of other possibly relative factors(P<0. 05). HDL-C of the former smokers was higher than smokers and TG was lower than heavy smokers(P<0. 05). Smoking was an independent risk factor for HDL-C ( P<0. 05 ,β= -0. 213 ) , and there was a significantly negative relationship between daily cigarette consumption and HDL-C ( r= -0. 223 , P<0. 05 ) . Conclusion Smoking is an important risk factor for the diabetic male patients’ metabolism of the TG and HDL-C,independent of age, body mass index, blood pres

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: Oleic acid has been shown to lower high blood pressure and provide cardiovascular protection. Curiosity arises as to whether super olein (SO, red palm olein (RPO and palm olein (PO, which have high oleic acid content, are able to prevent the development of hypertension. METHODOLOGY/PRINCIPAL FINDINGS: Four-week-old male spontaneously hypertensive rats (SHR and Wistar-Kyoto (WKY rats were fed 15% SO, RPO or PO supplemented diet for 15 weeks. After 15 weeks of treatment, the systolic blood pressure (SBP of SHR treated with SO, RPO and PO were 158.4±5.0 mmHg (p<0.001, 178.9±2.7 mmHg (p<0.001 and 167.7±2.1 mmHg (p<0.001, respectively, compared with SHR controls (220.9±1.5 mmHg. Bradycardia was observed with SO and PO. In contrast, the SBP and heart rate of treated WKY rats were not different from those of WKY controls. The SO and PO significantly reduced the increased heart size and thoracic aortic media thickness observed in untreated SHR but RPO reduced only the latter. No such differences, however, were observed between the treated and untreated WKY rats. Oil Red O enface staining of thoracic-abdominal aorta did not show any lipid deposition in all treated rats. The SO and RPO significantly raised serum alkaline phosphatase levels in the SHR while body weight and renal biochemical indices were unaltered in both strains. Serum lipid profiles of treated SHR and WKY rats were unchanged, with the exception of a significant reduction in LDL-C level and total cholesterol/HDL ratio (atherogenic index in SO and RPO treated SHR compared with untreated SHR. CONCLUSION: The SO, RPO and PO attenuate the rise in blood pressure in SHR, accompanied by bradycardia and heart size reduction with SO and PO, and aortic media thickness reduction with SO, RPO and PO. The SO and RPO are antiatherogenic in nature by improving blood lipid profiles in SHR.

    A suboptimal early nutritional environment (i.e., excess of energy, sugar, and fat intake) can increase susceptibility to diseases and neurocognitive disorders. The purpose of this study was to investigate in nonobese Yucatan minipigs (Sus scrofa) the impact of maternal diet [standard (SD) vs. Western (WD) diet] during gestation and 25 d of lactation on milk composition, blood metabolism, and microbiota activity of sows (n = 17) and their piglets (n = 65), and on spatial cognition (n = 51), hippocampal plasticity (n = 17), and food preferences/motivation (n = 51) in the progeny. Milk dry matter and lipid content, as well as plasma total cholesterol and free fatty acid (FFA) concentrations (P < 0.05) were higher in WD than in SD sows. Microbiota activity decreased in both WD sows and 100-d-old piglets (P < 0.05 or P < 0.10, depending on short-chain FAs [SCFAs]). At weaning [postnatal day (PND) 25], WD piglets had increased blood triglyceride and FFA levels (P < 0.01). Both SD and WD piglets consumed more of a known SD than an unknown high-fat/-sucrose (HFS) diet (P < 0.0001), but were quicker to obtain HFS rewards compared with SD rewards (P < 0.01). WD piglets had higher working memory (P = 0.015) and reference memory (P < 0.001) scores, which may reflect better cognitive abilities in the task context and a higher motivation for the food rewards. WD piglets had a smaller hippocampal granular cell layer (P = 0.03) and decreased neurogenesis (P < 0.005), but increased cell proliferation (P < 0.001). A maternal WD during gestation and lactation, even in the absence of obesity, has significant consequences for piglets' blood lipid levels, microbiota activity, gut-brain axis, and neurocognitive abilities after weaning.-Val-Laillet, D., Besson, M., Guérin, S., Coquery, N., Randuineau, G., Kanzari, A., Quesnel, H., Bonhomme, N., Bolhuis, J.

Significant differences (p<0.05 were detected in performance, carcass weight, weight and breast yield, and leg weight. The best results were obtained with 33 and 66 g/kg as compared to the control diet and 100 g SSM /kg. Abdominal fat decreased with the inclusion of 66 and 100 g SSM / kg, but the sensory quality of breast and thighs was not affected by the inclusion of SSM. The serum levels of total cholesterol, very low density (VLDL and low density (LDL lipoproteins, triglycerides, glucose and atherogenic index decreased with the inclusion of 100 g/kg of SSM, except for high density lipoproteins (HDL, which increased. The inclusion of 0, 33, 66 and 100 g/kg of SSM in broiler diets, partially replacing soybean meal and vegetable oil, improved live performance and edible portions yield. In addition, abdominal fat and serum levels of harmful lipids were reduced, whereas serum levels of beneficial lipids increased. There was no effect on meat sensory quality.

    Objective:To investigate the ability of the methanolic extract of pineapple peel to modulate alcohol-induced lipid peroxidation,changes in catalase activities and hepatic biochemical marker levels in blood plasma.Methods:Oxidative stress was induced by oral administration of ethanol(20%w/v) at a dosage of 5 niL/kg bw in rats.After 28 days of treatment,the rats were fasted overnight and sacrificed by cervical dislocation.Blood was collected with a 2 mL syringe by cardiac puncture and was centrifuged at 3000 rpm for 10 min.The plasma was analyzed to evaluate malondialdehyde(MDA),catalase activity,aspartate aminotransferase(AST),alkaline phosphatase(ALP) and alanine aminotransferase(ALT) concentrations.Results:Administration of alcohol caused a drastic increase(87.74%) in MDA level compared with the control.Pineapple peel extract significantly reduced the MDA level by 60.16%at 2.S mL/kg bw.Rats fed alcohol only had the highest catalase activity,treatment with pineapple peel extract at 2.5 mL/kg bw however, reduced the activity.Increased AST,ALP and ALT activities were observed in rats fed alcohol only respectively,treatment with pineapple peel extract drastically reduced their activities. Conclusions:The positive modulation of lipid peroxidation,catalase activities as well as hepatic biomarker levels of blood plasma by the methanolic extract of pineapple peels under alcoholinduced oxidative stress is an indication of its protective ability in the management of alcoholinduced toxicity.
