Filter by:Excessive fat in the liver, in absence of high alcohol consumption, is diagnosed as non-alcoholic fatty liver (NAFL). NAFL prevalence is as high as 50-70% in obese people and is associated with impairments in metabolic health, e.g. insulin resistance. Not only the amount, but also the composition of the fat stored in the liver appears to be linked to health outcome measures, such as insulin resistance, but this evidence comes mainly from animal studies. Since fat composition has been linked to health outcome measures, it is important to understand what determines the fatty acid composition of liver fat. De novo lipogenesis (DNL) and adipose tissue fat composition are factors that could determine liver fat composition. Since the end product of DNL are saturated fatty acids and as the majority of fatty acids in the liver originate from adipose tissue, both may influence hepatic fatty acid composition profoundly. Here, our primary hypothesis is that DNL is associated with the relative amount of saturated fatty acids in the liver in overweight/obese humans differing in liver fat content. Furthermore, we hypothesise that adipose tissue fat composition is associated with liver fat composition and that liver fat composition is associated with liver, muscle and whole body insulin sensitivity in overweight/obese humans differing in liver fat content. To this end, liver fat composition, adipose tissue fat composition, DNL and insulin sensitivity will be measured in overweight/obese participants differing in liver content.
The study will investigate myocellular signalling in skeletal muscle after insulin-stimulation and exercise in healthy young men
The objective of this trial is to compare the effects of a healthy, lean beef diet and an average American, United States Department of Agriculture (USDA) style diet, that is low in saturated fatty acids (SFA), on insulin sensitivity in men and women with risk factors for diabetes mellitus.
The objectives of this trial are to assess the effects of corn oil and coconut oil on low-density lipoprotein cholesterol (LDL-C) concentrations, and other aspects of the fasting lipoprotein lipid profile, as well as insulin sensitivity and an inflammatory marker, in men and women.
Progression of T2DM is widely accepted to be contributed by two main components: beta cell function deterioration where insulin secretion is impaired and insulin resistance where insulin physiological response is reduced. Insulin resistance and beta cell function will be estimated through a mathematical model, homeostasis model assessment. Fasting insulin and C-peptide will be measured using liquid chromatography tandem mass spectrometry. Insulin resistance and beta cell function is then compared with the glycaemic control, HbA1C.
This double-blind, placebo-controlled randomized trial will assess whether 14 days of oral carnitine supplementation modifies mitochondrial fatty acid processing in healthy young adults.
The purpose of this study is to elucidate the effects of Fluvastatin on brown adipose tissue activity in humans.
Background: Increases in obesity, diabetes, and some metabolic disorders may be linked to how much processed foods people eat. Researchers want to learn more about how processed foods affect metabolic health. Objective: To learn about how a processed versus unprocessed diet affects the body. Eligibility: Men ages 18-50 with stable weight and risk factors for diabetes Design: Participants will be screened over 3 visits. Screening includes: - Medical history and physical exam - Heart and blood tests - Psychiatric questions - Questions about eating, sleeping, and economic status - Riding a stationary bike - Trying a sample meal Between screenings, participants will eat prepared meals. They will wear an accelerometer to measure physical activity. They will write down what foods they eat and monitor their weight. Participants will have two 4-week stays in the clinic. They will: - Eat a special diet - Have activity and weight monitored - Drink water and collect urine samples to measure how many calories they are burning - Have resting energy expenditure measured with a clear hood over the head - Have a scan to measure body fat and bone density using low-dose x-rays - Have a scan on a table that slides into a metal cylinder in a strong magnetic field. They will get earplugs for the loud noises. - Have an ultrasound test to measure blood vessels - Have insulin and glucose infused into an arm vein. Blood will be taken over 10 hours through a plastic tube in the wrist. This will happen 4 times. - Spend multiple 24-hour periods in a room that measures oxygen used and carbon dioxide produced. - Give blood, urine and stool samples - Answer questionnaires and do computer tasks
The impact of a bilberry-based probiotic drink on the postprandial levels of serum glucose and insulin have already been study in the past. The aim of the current study is to evaluate the long term effect of the probiotic bilberry drink on glucose tolerance and insulin resistance in healthy adults and in comparison to a control drink.
It has been shown that insulin might be involved in the pathogenesis of thyroid growth. Objective To evaluate the impact of IR and metformin use on the volume of benign thyroid nodules (TNs). Methods A randomized clinical trial to placebo (P) or MTF use. Previous fine needle aspiration confirming the diagnosis is necessary to inclusion. Patients will receive similar tablets of MTF and placebo and instruct to take 3 tablets/day of MTF (500mg/tablet). Thyroid volume, as TN volume, will be assess by ultrasound, both in the beginning, six months and one year after randomization, by the same researcher blinded regarding location group. Blood samples to measure: TSH, FT4, TPO-Ab, lipid profile, glucose and insulin were done after 8h fasting.
