It is still unclear whether microvascular complications of type 2 diabetes correlate with leukocyte-endothelium interactions and/or myeloperoxidase (MPO) levels. In the present study, we found that serum levels of glucose, the rate of ROS and MPO concentration were higher in type 2 diabetic patients. Patients with nephropathy (39.6%) presented higher MPO(More)
BACKGROUND & AIMS Inositols are thought to be mediators of the insulin signalling pathway. We assessed the effects of inositols on glycaemic control in fasting and postprandial states and evaluated lipoprotein profile and LDL particle size in healthy population. METHODS A 12-week double-blind clinical trial was performed with forty healthy subjects(More)
Nitric oxide (NO) has an important role in physiological and pathological processes in general, and in particular plays a homeostatic role in the nervous and immune systems. The many different physiological functions of NO include those of a mediator of blood vessel dilation, neurotransmitter, neuromodulator and inductor of mitochondrial biogenesis. In(More)
Endothelial dysfunction involving dysfunctional mitochondria precedes the development of cardiovascular diseases. This impairment results from an increase in reactive oxygen species, which leads to oxidative stress and a reduced bioavailability of nitric oxide. It has been demonstrated that oxidative stress and alterations in glucose and lipid homeostasis(More)
Evidence is mounting of the involvement of mitochondrial dysfunction in insulin resistance, diabetes and associated complications. This review aims to provide an overview of the effects of insulin resistance on mitochondrial function in several tissues. We consider the pathogenesis of insulin resistance from a mitochondrial perspective and contemplate(More)
CONTEXT Anorexia nervosa is a common illness among adolescents and is characterised by oxidative stress. OBJECTIVE The effects of anorexia on mitochondrial function and redox state in leukocytes from anorexic subjects were evaluated. DESIGN AND SETTING A multi-centre, cross-sectional case-control study was performed. PATIENTS Our study population(More)
OBJECTIVE Oxidative stress and mitochondrial dysfunction are implicated in polycystic ovary syndrome (PCOS). The present study assesses the effect of metformin treatment on mitochondrial function in polymorphonuclear cells from PCOS subjects. Additionally, we evaluate endocrine parameters and levels of interleukin 6 (IL6) and tumour necrosis factor alpha(More)
Type 2 diabetes can increase the risk of skeletal muscle dysfunction and, consequently, that of cardiovascular diseases, including coronary artery disease and stroke. It is also related to a reduced capacity for exercise, but the underlying mechanism is only partially understood. There are several factors that contribute to the development of skeletal(More)
