Filter by:The study is designed to compare muscle energy capacity in men with obesity or diabetes as compared to athletes. This study will also enable researchers to determine whether MRS can replace muscle biopsy for this type of assessment.
Insulin resistance is a central feature of Diabetes mellitus type 2 (Stumvoll et al. 2005). Hypo- and hyperglycemic states are associated with adverse inpatient outcomes (ADA et al. 2006 Diab Care) and with the development of microvascular complications (UKPDS 34 Lancet 1998). A long known therapy for the acute treatment of patients with deteriorated glucose metabolism and insulin resistance are carbohydrate days. The principle of the therapy was firstly introduced in 1903 by Carl von Noorden (Noorden et al. 1903). The diabetic patients were treated for several days with a carbohydrate rich diet with fat restriction. Surprisingly, this resulted in an amelioration of glucosuria. Today it's still a valuable tool for patients with uncontrollable diabetes mellitus and severe insulin resistance (Willms B. 1989). But up to now there has been no systemic evaluation of carbohydrate days in patients with deteriorated Diabetes mellitus and insulin resistance. The investigators conducted a pilot study with 14 patients to evaluate the efficacy of two days of oatmeal on insulin resistance and glucose metabolism in an acute clinical setting and after a four week outpatient period. Inclusion criteria were type 2 diabetes with deteriorated glucose metabolism, insulin resistance defined as an insulin dosage of more than 1 U per day and kg bodyweight. Within this pilot trial the investigators found a marked decrease of insulin requirements (~40%) and mean daily blood glucose to a mean blood glucose of 114.7±36.7 mg/dl in the acute setting as well as after the four week outpatient period (Lammert et al. 2006). The most important shortcomings of this study were the hypocaloric interventions in both groups (diabetes-adapted diet: 1500kcal/d vs. oatmeal 1200kcal/d) making it difficult to attribute the observed effects to oatmeal alone as well as the uncontrolled nature. These design flaws have been addressed within this new clinical trial. The investigators plan an open label, cross-over study with isocaloric interventions (oatmeal and diabetes-adapted diet: ~ 1200kcal/d). The intervention comprises two days of oatmeal (third and fourth day) within a 5 day hospital stay. The control is only treated with 5 days of diabetes adapted diet. Thereafter, the patients are followed every four weeks for an overall of 16 weeks.
The objective of the study is to determine whether Panax Ginseng with multiple interactions with key components of brain signaling pathway, can augment the effects of antipsychotics in Schizophrenia. We are primarily interested to examine the actions of Ginseng combined with antipsychotics in improving the ways patients diagnosed with schizophrenia behave in social environment, store, process and retrieve information.
The objective of our research project is to determine the effects of fish protein, present in fish, on insulin sensitivity in insulin-resistant human individuals, and its mechanism of action on glucose metabolism. Our hypothesis is that fish protein improves insulin sensitivity, glucose tolerance and plasma lipid profile through an improvement in a primary defect in insulin signaling in overweight and insulin-resistant subjects.
The purpose of this study is to determine whether the investigational drug INCB013739 has an effect on systemic and adipose tissue 11-HSD1 activity in obese, insulin resistant subjects.
Visceral obesity is strongly associated with dyslipidaemia (hypertriglyceridaemia, low HDL-cholesterol and mildly elevated LDL-cholesterol) and insulin resistance, key characteristics of metabolic syndrome (MetS). Recent evidence has clearly established that the risk of CVD is increased in subjects with the MetS. The precise reason for this remains unclear, but appears to be closely related with dyslipidaemia. Effective management of dyslipidaemia is important to reduce the risk of CVD in these subjects. Hypothesis: Inhibition of hepatic cholesterol synthesis by statins and triglyceride synthesis by fish oils improve lipoprotein metabolism in visceral obese men.
The purpose of this study is to evaluate the metabolic and anti-inflammatory effects of eccentric endurance exercise and to compare them with those of concentric exercise in healthy sedentary individuals.
Background: 18B Glycyrrhetinic acid (active compound of Licorice) decreases serum potassium via enhanced renal potassium loss in healthy individuals and thereby inducing renal sodium retention and arterial hypertension.In dialysis patients this mechanism is disturbed and compensatory intestinal potassium secretion is enhanced. 18B Glycyrrhetinic acid is an inhibitor of 11B Hydroxysteroid dehydrogenase type 1 (11b HSD1). Inhibition of 11 b HSD1 offers a novel potential therapy to lower intracellular cortisol concentrations and thereby enhance insulin sensitivity. Hypothesis: Glycyrrhetinic acid decreases serum potassium by enhanced intestinal excretion in dialysis patients and increases insulin sensivity by inhibition of 11b HSD Methods: double blind, 6 month cross over trial comparing oral 18b Glycyrrhetinic acid with placebo in 24 nondiabetic dialysis patients. Endpoints: predialytic serum potassium levels, insuline sensitivity assessed by fasting glucose and fasting insulin concentrations
To better understand the mechanisms leading to lymphedema development in breast cancer survivors, and the implications for potential innovative approaches to the screening, prevention and treatment of this condition.
We hypothesize that Asian Americans compared to Caucasians, will be at higher risk of developing a pro-inflammatory state that may contribute to the development of heart disease and diabetes when they change from a traditional Asian diet to a typical Western diet. These inflammatory responses will be reflected by the activation of monocytes as measured by protein kinase C (PKC), a known activator of monocytes. We also hypothesize that the changes of these inflammatory responses in the gingival crevicular fluid (GCF) will reflect similar changes of these markers in the plasma and monocytes. Specific aims: 1. To compare the inflammatory responses (primarily PKC activation in monocytes), between Far-East Asian Americans and Caucasian Americans, when they change from a traditional Asian diet to a typical American diet. 2. To correlate the biochemical changes of inflammatory responses in the plasma and monocytes with those in the gingival crevicular fluid (GCF).
