Introduction: Post-prandial hyperglycaemia seems to play a pivotal role in the pathogenesis of cardiovascular complications of diabetes mellitus, as it leads to oxidative stress which in turn causes reduced NO bioavailability that produce endothelial activation.Aim: Aim of the study was to assure that the administration of N-acetylcysteine (NAC), thiolic antioxidant, is able to decrease oxidation status and endothelial activation after a high-gluc...

Introduction: Nitric oxide (NO) plays a wide spectrum of biological actions including a positive role in oocyte maturation and ovulation. Free radicals have been shown elevated in PCOS and therefore would be responsible for quenching NO that, in turn, would play a role in determining oligo or amenorrhea connoting PCOS. We recently demonstrated that the combined administration of N-acetylcysteine (NAC) and arginine (ARG) is able to exert an antioxidant action leading to ...

Objective: Reactive oxygen species and nitric oxide (NO) have recently been considered involved in the cardiovascular complications of patients with type 2 diabetes as NO is supposed to loose its physiological beneficial effects, due to the presence of oxygen radicals. For this reason, we tested the effects of L-arginine (ARG) and N-acetylcisteine (NAC) administration with the aim to increase NO physiological production reducing free radical formation.</p...
