Filter by:Acute coronary syndrome (ACS) is a lethal disease, reduced low-density lipoprotein (LDL) cholesterol due to inhibition of proprotein convertase subtilisin/kexin 9 (PCSK9) reduces cardiovascular events and improve cardiovascular prognosis. we assuming that PCSK9 inhibitor could bring metabolic change in serum, in order to investigate the metabolic modification, we conduct this clinical trial.
Background: Among the risk factors associated with aging, a special highlight has been attributed to cardiovascular dysfunctions, insulin resistance, central obesity and dyslipidemia, which is marked by low levels of cholesterol (high density lipoprotein) and in particular by high levels of plasma triglycerides. Individuals with high levels of plasma triglycerides tend to have a prolonged postprandial hypertriglyceridemia after a fat-meal challenge, which would potentially further increase the risk associated with cardiovascular disease. Due to the impact of aging and its associated risk factors on the older adults health, several strategies have been proposed to avoid the progression of chronic diseases. These diseases are frequent in this population, especially the ones that resides in long-term institutions and they are mainly characterized by sedentary lifestyle and functional inability. Systematic reviews have shown that the implementation of physical activity programs associated with a favorable dietary pattern may benefit the lipid profile of the older adults. Moreover, it is suggested as a primary strategy, the realization of physical exercise as a therapy for this disease. In the physical exercise programs aspects, unconventional modalities such as Capoeira, which is practiced in more than 150 countries, it has aroused interest in the scientific research. Characterized by a system composed by attack and defense movements and from Afro-Brazilian origin, Capoeira combines sports elements of the fight, gymnastics, dance and musicality. However, there is no study investigating the effect of Capoeira training on the lipid profile of older adults, which would have an important clinical application in the health of this population, especially living in conditions of sedentarism and frailty in long-term institutions. Aim: The present study analyzed the effects of twelve weeks of Capoeira training on the lipid profile of advanced-age frail adults of a long-term institution, which are characterized by sedentary lifestyle and affected by several diseases. Methods: Participants were assigned into two groups (CONTROL: n = 07; 82.4±13.6 years and CAPOEIRA: n = 07; 79.4±6.9 years). The CAPOEIRA group performed twelve weeks of Capoeira training program, being twice a week lasting 60 minutes each at light to moderate intensity. Samples of 10 ml of blood were collected from participants' antecubital vein at the pre- and post-intervention moments in both groups. Plasma concentrations of triglycerides, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol were evaluated using the enzymatic colorimetric method. Anthropometry measures were performed and to internal control the energy consumption evaluations were carried out through daily food diaries during intervention period.
Elevated levels of plasma triglycerides are increasingly recognized as an important causal risk factor for cardiovascular disease and associated pathologies. Lowering plasma triglycerides may therefore be a therapeutic target to lower cardiovascular disease risk. With this study the investigators want to examine the effects of fasting on adipose tissue metabolism in humans.
The objective of this study is to assess whether intake of baked and then chilled potatoes over a 24-h period, compared to intake of isocaloric, carbohydrate (CHO)-matched foods low in fiber and resistant starch (RS), will increase insulin sensitivity, breath hydrogen and satiety, and decrease hunger and free fatty acid (FFA) levels in overweight or obese men and women at risk for metabolic syndrome and diabetes mellitus.
The interventional study will evaluate the effects of a regularly consumption of barley and oat flakes in crude and roasted form on the glucose and lipid metabolism as well as the postprandial saturation. Moreover, the study will evaluate the effect of a regularly consumption of barley and oat flakes on the glucose and lipid metabolism over a period of three weeks. All participants will run through each intervention (cross-over design). Inbetween these intervention periods there will be wash-out phases. In total there will be four interventions: crude oat flakes, roasted oat flakes, crude barley flakes and roasted barley flakes. The comparison will be made against white toastbread. The study participants will visit the study centrum before and after each intervention over an entire period of 27 weeks.
The purpose of this study is to investigate the effects of egg intake on markers of HDL function and immune inflammation in healthy adults.
There are numerous factors known to determine the relative rate of lipid metabolism at rest between and within individuals, including: biological sex, endogenous carbohydrate availability, training status and, in particular, feeding. Recent focus has been placed on the potential of alternative nutrients, nutritional supplements and pharmacological agents to modify substrate selection in favour of greater lipid oxidation (e.g. caffeine, carnitine, green tea) and/or to alter lipid absorption (e.g. caffeine, carnitine, orlistat, green tea preparations). Polyphenol-rich tea extract can have effects on lipase activity in the pancreas causing reduced fat absorption. The present study is to assess the potential for tea extract alone to be as effective at the liquid product in a western population.
The main objective of the study is to evaluate the endothelial function of WAK2017. In addition the effects on the blood pressure and the parameters of lipid metabolism will be explored.
Raised blood cholesterol (also referred to as blood LDL-cholesterol) is a major risk factor for developing heart disease. Dietary saturated fat is recognised as the main dietary component responsible for raising blood LDL-cholesterol, and reducing its intake has been the mainstay of dietary guidelines for the prevention of heart disease for over 30 years. However, there is very little evidence for a direct link between the intake of saturated fat and risk of dying from heart disease. One explanation for this, is that the link between saturated fat intake and heart disease is not a direct one, but relies heavily on the ability of saturated fat to raise blood LDL-cholesterol levels. This LDL cholesterol-raising effect of saturated fat is complex, and highly variable between individuals because of differences in the metabolism of dietary fat and cholesterol between people. The main aim of this study is to measure the amount of variation in blood LDL-cholesterol in healthy volunteers at the Universities of Surrey and Reading in response to lowering the amount of saturated fat in the diet to the level recommended by the government for the prevention of heart disease. This collaborative project between the Universities of Reading, Surrey and Imperial ('RISSCI-1' Blood Cholesterol Response Study') will permit identification of two subgroups of men who show either a high or low LDL-cholesterol response to a reduction in dietary saturated intake. These two groups of participants will be provided with an opportunity to participate in a similar follow-up study ('RISSCI-2') that will also take place at the University of Surrey and Reading. In this follow-up study, the participants will be asked to repeat a similar study protocol as for RISSCI-1, but undergo more detailed measurements to investigate the metabolic and genetic origins of how saturated fat is metabolised in the body and influences blood LDL-cholesterol (LDL-C).
The ability to upregulate fat oxidation at appropriate times such as during fasting, low to moderate intensity exercise and after a high fat meal, is popularly advocated. This is presumably due to the perception that a high capacity to utilise fat may improve (ultra) endurance performance and help in the regulation of body fat and metabolic diseases. In accordance, impaired fat use at rest has been associated with obesity and insulin resistance (Kelley et al., 1999). However, there is inconclusive and / or a lack of systematic evidence, especially in a large diverse range of adults, exploring: 1) Whether whole body fat use during exercise is altered in individuals with overweight or obesity compared to lean individuals 3) The intra-individual variability in whole-body fat use at rest and during exercise 4) Physiological, metabolic, lifestyle and genetic characteristics that are associated with whole-body fat use at rest and during exercise Therefore, the objectives of this study are three-fold: 1. To explore whether whole body fat use is associated with body composition 2. To explore associations between whole-body fat use and physiological, metabolic, lifestyle and genetic variables 3. To assess the intra-individual variability of whole-body fat use. This study is an observational, exploratory cross-sectional study. A wide range of 'healthy' and 'at-risk of metabolic disease' adults will be recruited. Participants will be asked to visit a laboratory at the University of Bath four times. Visit 1 is a screening and study familiarisation visit. Visits 2 and 3 are to be completed within 7-14 days and involve lifestyle monitoring (dietary and physical activity), a one-off urine and blood sample, assessment of fuel use at rest and during exercise (the latter through an incremental graded cycling exercise test to exhaustion). Visit 4 is to assess body composition via a dual-energy x-ray absorptiometry (DEXA) scan in addition to an optional skeletal muscle and / or fat tissue biopsy.
