Filter by:To investigate whether co-administration of lactate with a glucose load affects postprandial glucose levels/handling, gastrointestinal hormones, gastric emptying, and appetite sensations in individuals with pre-diabetes when compared to placebo. Hypothesis: Oral lactate administration improves/lowers glucose excursions following an oral glucose tolerance test (OGTT) by stimulating insulin secretion and delaying glucose absorption.
The goal of this randomized controlled trial is to test the effect of time-restricted eating (14-hour fast, 10-hour eating window) of a low-energy dense diet (reduced calories per gram of food) in older adults with obesity and insulin resistance. The study aims to determine if modulating the energy density of the diet reduces: 1. Insulin resistance and 2. Body weight. Researchers will compare the groups: 1. Following time-restricted eating and given a diet reduced in energy density or 2. Following time-restricted eating and given a diet typically consumed in this population
Females treated with antipsychotics have higher rates of comorbid metabolic syndrome than males. Despite this, females have historically been excluded from many mechanistic studies due to confounding effects of menstrual cycles. Recent evidence suggests that brain insulin resistance may be an underlying mechanism through which antipsychotics may exert their metabolic side effects. This study seeks to investigate how brain insulin action differs in females according to their menstrual cycle phase, and how a high metabolic liability agent such as olanzapine might interrupt these differential insulin effects. Young healthy females will be given olanzapine and intranasal insulin to test how these treatment combinations change brain processes. Participants will be tested during both the first half of their menstrual cycle (follicular phase) and the second half of their cycle (luteal phase). We predict that intranasal insulin will change MRI-based measures in females, in a comparable way to males, in the follicular phase only. Adding olanzapine will block these effects of insulin in females in the follicular phase. This investigation has the potential to generate new knowledge in an area of significant unmet need. Demonstrating that antipsychotics disrupt brain insulin action, evidenced by inhibition of recognized effects of insulin on neuroimaging measures, will provide novel insights into currently poorly understood mechanisms.
The goal of this study is to collect more information from people with plaque psoriasis and to determine if insulin plays a role in the pathogenesis of psoriasis. The main question it aims to answer is if insulin action is preserved or even enhanced in psoriatic lesions despite insulin resistance elsewhere. Participants with plaque psoriasis will have punch biopsies taken of lesional and non-lesional skin after an overnight fast and then during an oral glucose tolerance test. Biopsy specimens will then be assessed for markers of insulin action.
A combination of generally regarded as safe (GRAS) compounds named GLY-LOW, which included: alpha lipoic acid, pyridoxamine, nicotinamide, piperine and thiamine, were examined in pre-clinical experiments. GLY-LOW supplementation reduced caloric intake and increased insulin sensitivity in mice. In female mice, GLY-LOW supplementation reversed aging-related declines in female hormones. Studies in humans are needed to examine the feasibility, utility and efficacy of GLY-LOW supplementation in post-menopausal women with obesity toward improving aging-related impairments. The effect of GLY-LOW supplementation on these obesity and biological age-related impairments in post-menopausal adult female humans with obesity is unknown. We aim to translate the findings of GLY-LOW supplementation in animals to a cohort of healthy, postmenopausal females at birth with obesity by conducting a one-group, no-placebo comparer, pre post intervention clinical trial. Additionally, we propose to examine the specific effect of supplementation by GLY-LOW on biological aging via retina scan. The objectives of the proposed pilot study are: I. Conduct a 6-month pilot study to examine the feasibility, utility and efficacy of GLY-LOW supplementation in a total of 40 postmenopausal female born adults > 55 years with obesity (> 30 BMI) Ia. Examine alterations in self-reported caloric intake and the following health and biological aging, parameters prior to and after 6 months of GLY-LOW supplementation: 1. Self-reported Caloric Intake 2. Metabolic disease risk 3. Cardiovascular disease risk 4. Metabolic assessments 5. Hormones 6. Physical Function and Fitness 7. Muscular strength 8. Cognitive Function and Depression assessments 9. Systemic inflammation 10. Biological aging 11. Safety parameters (also every 2 months during the intervention; ECG at baseline and 2 months only) 12, Compliance measures (pill counts and interviews every 2 months during the intervention)
The aim of this study is to investigate the effectiveness of a home-based walking-based exercise intervention undertaken in the fed or fasted state to improve glycaemic control in overweight and obese individuals. This study will evaluate the adherence and compliance to this "real-world" exercise programme that requires no face-to-face contact with the research team. It is also hypothesised that individuals who exercise before breakfast (fasted) will see greater improvements in glycaemic control than those who exercise after breakfast.
In this retrospective study from professor Kojuri clinic registry, total number of 1017 patients with first angiography were included and all data were recorded from registry. Insulin resistance was calculated using laboratory data
Diabetes mellitus (DM) is a complex chronic illness associated with a state of high blood glucose level, or hyperglycemia, occurring from deficiencies in insulin secretion, action, or both. Diabetes mellitus is the name given to a wide spectrum group of disorders characterized by raised plasma glucose.Type 1 diabetes is characterized by an absolute insulin deficiency due to autoimmune destruction of insulin producing beta cells in the pancreas. most adults with diabetes have type 2, characterized by a relative insulin secretory defect, and target tissue resistance to the effects of insulin.
The purpose of the proposed study is to compare the acute effects of different types of exercise modalities on glucose handling in young, healthy males and females. The exercise modalities that will be compared include: a high intensity interval exercise (HIIE) protocol, a moderate intensity continuous exercise (MICE) protocol and a low-load, high-repetition (LL-HR) resistance exercise protocol.
In humans, insulin is secreted in pulses from the pancreatic beta-cells, and these oscillations help to maintain fasting plasma glucose levels within a narrow normal range. Given the fluctuations in insulin concentrations, oscillations enhance precision of control. The hyperinsulinemic euglycemic clamp test (clamp) involves a continuous infusion of insulin and is the gold standard for measuring insulin sensitivity. In this study, insulin sensitivity measured using the standard clamp will be compared with a clamp in which the same total amount of insulin as the standard clamp is infused every five minutes instead of continuously.
