BACKGROUND Patients with type 2 diabetes are at high risk of fatal and non-fatal myocardial infarction and stroke. There is indirect evidence that agonists of peroxisome proliferator-activated receptor gamma (PPAR gamma) could reduce macrovascular complications. Our aim, therefore, was to ascertain whether pioglitazone reduces macrovascular morbidity and(More)
Oxidative stress has been ascribed a role in the pathogenesis of diabetes and its complications, and stress proteins have been shown to protect organisms in vitro and in vivo against oxidative stress. To study the putative role of one of the most abundant cytoprotective stress proteins, inducible cytoplasmic 72-kDa-mass heat shock protein (Hsp-72), in the(More)
OBJECTIVE To compare efficacy and safety of lixisenatide once daily versus exenatide twice daily in type 2 diabetes inadequately controlled with metformin. RESEARCH DESIGN AND METHODS Adults with diabetes inadequately controlled (HbA1c 7-10%) with metformin were randomized to lixisenatide 20 μg once daily (n=318) or exenatide 10 μg twice daily (n=316) in(More)
RESEARCH DESIGN AND METHODSdAdults with diabetes inadequately controlled (HbA1c 7–10%) with metformin were randomized to lixisenatide 20 mg once daily (n = 318) or exenatide 10 mg twice daily (n = 316) in a 24-week (main period), open-label, parallel-group, multicenter study. The primary objective was a noninferiority assessment of lixisenatide versus(More)
BACKGROUND Non alcoholic fatty liver disease (NAFLD) is an independent cardiovascular (CV) risk factor which is closely associated with insulin resistance measured by both direct or indirect methods. Gender specific findings in the relationship between alanine aminotransferase (ALT) and CV disease, the prevalence of NAFLD and type 2 diabetes (T2DM) have(More)
Multiple unit activity (MUA) of brain stem, hypothalamic and limbic structures was studied during habituation to a novel environment and circadian rhythm in chronically implanted freely moving rats. MUA was analysed in the mesencephalic reticular formation (MRF), area hypothalami posterior (PH), basal nuclear group of amygdala (AMY), area septalis (SEPT),(More)
BACKGROUND Insulin resistance has been recognized as the most significant predictor of further development of type 2 diabetes mellitus (T2DM). Here we investigated the effect of a heat shock protein (HSP) co-inducer, BGP-15, on insulin sensitivity in different insulin-resistant animal models and compared its effect with insulin secretagogues and insulin(More)
Genome-wide association studies (GWAS) have identified more than 65 genetic loci associated with risk of type 2 diabetes. However, the contribution of distorted parental transmission of alleles to risk of type 2 diabetes has been mostly unexplored. Our goal was therefore to search for parent-of-origin effects (POE) among type 2 diabetes loci in families.(More)
According to the "membrane sensor" hypothesis, the membrane's physical properties and microdomain organization play an initiating role in the heat shock response. Clinical conditions such as cancer, diabetes and neurodegenerative diseases are all coupled with specific changes in the physical state and lipid composition of cellular membranes and(More)
