Filter by:The aim of the present study is to investigate the effect of endurance on PSA doubling time in prostate cancer patients with an elevation in PSA following radical prostatectomy for localized cancer. Furthermore, underlying mechanisms such as reduction in inflammatory markers and improvement in insulin sensitivity and body composition are investigated.
Aims: To evaluate the efficacy of rosiglitazone (TZD) and electroacupuncture (EA) combined therapy on patients with type 2 diabetes mellitus (T2DM). A randomized single-blind placebo controlled clinical trial was used. Methods: A total of 31 newly diagnostic type 2 diabetic patients, who fulfilled the eligibility criteria were recruited and received various allocated interventions. They were randomly assigned into two groups, the control group (TZD, N=15) and the experimental group (TZD + EA, N=16). Changes in their plasma free fatty acid (FFA), glucose and insulin levels together with their homeostasis model assessment (HOMA) indices were statistically assessed between before and after treatment. Hypoglycemic activity (%) was also compared between these two groups. Expecting Results: This study will compare the hypoglycemic activity and the ability of improving insulin resistance between the TZD and TZD+EA group. Also, the lowering effect of the plasma FFA concentration will be investigated.
The purpose of this study is to investigate the effects of lowered physical activity (resulting in decreased muscle mitochondrial oxidative capacity) alone and together with increased plasma free fatty acid availability (by infusion of a clinically widely used lipid emulsion (Intralipid)) on insulin sensitivity and glucose and lipid metabolism. To this end, we will compare skeletal muscle insulin sensitivity and glucose and lipid metabolism (within one subject) after 9 days of immobilization of one leg (unilateral lower limb suspension(ULLS))(decreased muscle mitochondrial oxidative capacity) versus an active control leg (unchanged muscle mitochondrial oxidative capacity). Further, changes in IMCL and fatty acid intermediates will be investigated in the immobilized vs the control leg, and this will be related to insulin sensitivity. The effectiveness of the ULLS intervention will be tested by measuring muscle mitochondrial oxidative capacity in both the immobilized and the control leg. All measurements will be performed both in the immobilized and control leg after 9 days of ULLS.
Objectives: The investigators examined whether rosiglitazone, a thiazolidinedione (TZD), is beneficial for pre-diabetes mellitus (DM) adults with documented coronary artery disease (CAD). Background: Microvascular and macrovascular complications are common in type 2 DM. There is no evidence about the effects of TZDs, synthetic peroxisome proliferator-activated receptor (PPAR)-γ activators (insulin sensitizers and adipose transcriptional regulation and anti-inflammatory process activators) on pre-DM patients with documented CAD.
Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies in reproductive-age women, and it affects 5-7% of this group. It is characterized by disturbed menstrual cycle, ovulatory dysfunction and hyperandrogenism. Over 40% of PCOS women might become the patients with impaired glucose tolerance or type 2 diabetes. It has been confirmed that insulin resistance (IR) is a common feature in PCOS and adipokines might play roles in the pathogenesis of IR and PCOS, because these adipokines have wide-ranging effects on carbohydrate and lipid metabolism. The present clinical trial intends to compare the effects of metformin and oral contraceptives on PCOS patients, focusing on the insulin sensitivity, ovulation, and menstrual cycle etc. The investigators also aim to study the effects of metformin on serum adipokine levels(such as pigment epithelium-derived factor, progranulin etc.)in PCOS patients.
The purpose of this study is to evaluate efficacy of phlebotomy on insulin sensitivity as evaluated by euglycemic-hyperinsulinic clamp in insulin resistance-associated hepatic iron overload patients.
In obese women with polycystic ovary syndrome (PCOS), weight loss improves insulin resistance and hyperandrogenism, resulting in improvement of clinical symptoms. Weight loss is not required in lean PCOS patients; nevertheless, the influence of meal timing and composition on glucose metabolism and hyperandrogenism may have clinical value. In this study the investigators investigate the effects of two isocaloric diets with different meal timing distribution on insulin resistance and hyperandrogenism in lean PCOS patients.
Insulin resistance is one of the main mechanisms involved in metabolic diseases. inflammation has been implicated in its pathogenesis, due to innate immunity activation by free fatty acids, lipopolysaccharides (LPS) and lactate. Free fatty acids, LPS and lactate activate innate immunity in squelettal muscle and adipose tissue via Toll-like receptor 2/4, NFkB, IRF3 (Interferon Responsive Factor 3) and cytokines secretion (TNFa, IFN g, IL1b, IL6), chemokines secretion (MCP1) and leukotrienes (LTB4). Feed back mechanisms involved in TLR signaling pathways as RLI (ribonuclease L inhibitor)/ABCE1, have never been studied in inflammation due to obesity. RLI inhibits an endoribonuclease, RNase L, which has been recently implicated in TLR signaling The purpose of this study is to analyse the role of RLI and RNase L in TLR regulation, and its potential implication in the link between obesity, inflammation and insulin resistance in adipose tissue and squeletal muscle in humans.
The purpose of this study is to see how an insulin sensitizing medication, Pioglitazone, can cause changes in mood in some depressed patients. Study participants receive assessment of their cognitive and metabolic functioning. If they meet criteria, they will be asked to take either Pioglitazone or a placebo for a 90-day trial. Participants will undergo an Oral Glucose Tolerance Test to measure fasting insulin and glucose levels, as well as routine blood testing. The investigators hope to quantify the role of Pioglitazone in patients with mood disorders and compare the values to those previously obtained in a healthy age-matched control population. The investigators also hope to examine the association between IR and cognitive performance and clinical course of depression in patients with mood disorders.
Non-alcoholic fatty liver disease (NAFLD) has reached epidemic proportions and is rapidly becoming the one of most common causes of chronic liver disease in children. The pathogenesis of NAFLD is generally considered the result of a series of liver injuries, commonly referred as "multi-hit" hypothesis. Insulin resistance and increased serum levels of free fatty acids (FFAs) are considered the main primary hits that lead to the excessive lipid accumulation in hepatocytes resulting in steatosis. Has been reported that a diet rich in high-viscosity fiber improves glycemic control and lipid profile, suggesting a therapeutic potential role in the treatment of NAFLD. Aim of this study is to evaluate the efficacy and tolerability of glucomannan in children affected by non alcoholic fatty liver disease.
