Active clinical trials for "Metabolic Diseases"

The purpose of this study is to test whether compounds found in strawberries (polyphenolics which are typically found in berry products, tea, coffee, red wine, and chocolate) will help reduce insulin resistance and inflammation, known factors in your blood associated with disease risk, when eaten with a standard high fat/carbohydrate meal.

The purpose of this study is to characterize the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of PF-04991532 following multiple (14 days) escalating oral doses in patient wtih type 2 diabetes.

Mainly due to the absence of gravitational forces in weightlessness, astronauts suffer from an increased bone loss- negatively affecting health and vitality during a mission. The development of effective countermeasures to this loss includes many different aspects like sports but also nutrition. Alkaline salts, abundant in fruits and vegetables, have shown to have positive effects on markers of bone turnover of postmenopausal women but also men and younger adults. With the current study the effects of a potassium bicarbonate supplementation added to a standardised, strictly controlled, definite diet of healthy, young men, should be verified within 21 days of 6°- HDT- Bedrest- the gold standard of simulating weightlessness within earthbound conditions.

Since diabetes has multiple etiologies and oxidative stress one of the proposed mechanisms, the objective is to determine the effect of supplementation with β-carotene to type 2 diabetics and healthy individuals, on iron metabolism, oxidative balance, and antioxidant plasma capacity, using doses similar to the daily nutritional requirement.

This study aims to find out how consuming different proteins with rice affect metabolism. Most meals the investigators eat predominantly consist of a carbohydrate and protein (i.e. rice, noodles, bread etc with meats or seafood). However, it is still unknown how consuming different proteins with commonly eaten carbohydrates affect metabolism. Previous studies have shown that proteins stimulate hormones such as insulin, glucagon and gut hormones. However, the extent of the response depends on protein type. The metabolic responses to carbohydrates have also been shown to be greatly affected when they are eaten with proteins. However, most of the previous studies have used glucose as the carbohydrate and it is still unknown how eating proteins with carbohydrate foods such as rice affect metabolism. Therefore, this study has been initiated to determine the metabolic effects of eating different protein types with rice. Using the most common carbohydrate eaten in Asia (rice) and four commonly eaten protein foods (egg, chicken, fish and beancurd), this study aims to observe the metabolic effects of co-ingesting proteins and carbohydrate. The resulting data will provide valuable insights into the metabolic effects of protein-carbohydrate meals and will be useful in the development of practical advice and dietary guidelines for those with chronic diseases (such as diabetes and obesity).

Many patients in the hospital who are malnourished or not eating received intravenous feeding or total parenteral nutrition (TPN). Despite improving nutrition, TPN may increase the risk of infections and hospital complications. We do not know why TPN increases hospital complications, but it may be caused by the high sugar or fat content in TPN solutions. The investigators believe that the high sugar and high fat content can limit the ability to fight infections and produce stiffness of blood vessels. This study will compare the effect of high sugar, high fat content or both on blood sugars, blood vessel function, on blood vessel function. The investigators will also compare the effect of different fats (olive oil and soybean) in the TPN solution on the risk of infection and blood vessel function on a total of 12 healthy subjects.

Subjects with impaired glucose tolerance will be randomized to receive pioglitazone or metformin for 10 weeks. Measurements of insulin sensitivity, body composition, glucose tolerance, and muscle lipid accumulation will be performed. Adipose tissue and muscle biopsies are performed. The goal of the study is to determine whether the lipotoxiciy of impaired glucose tolerance is ameliorated by pioglitazone.

The objective of this research was to investigate the impact of Omega-3 PUFAs on the gut microbiota and serum lipid metabolites in participants diagnosed with type 2 diabetes, employing high-throughput sequencing technology and untargeted lipidomics.

In this study the effects of sucralose on insulin sensitivity, beta-cell response and appetite regulating hormones will be evaluated.

The hypothesis of the present study is that physical training can oppose detrimental changes in cardiovascular and metabolic health associated with estrogen loss after menopause.
