Experimental models for the investigation of nerve regeneration are critical in studying new strategies able to promote the repair process. The aim of the present work was to characterize morphological and functional aspects of sciatic nerve regeneration after mechanical crush injury in rodents. Morphological changes were assessed after a four minutes(More)
High-resolution respirometry of permeabilized myocardial fibers offers reliable insights concerning the integrated mitochondrial function while using small amounts of cardiac tissue. The aim of the present study was to assess the respiratory function in permeabilized fibers of human right atrial appendages harvested from patients with coronary heart disease(More)
It is widely recognized that mitochondrial dysfunction is a key component of the multifactorial process of ageing. The effects of age on individual components of mitochondrial function vary across species and strains. In this study we investigated the oxygen consumption, the mitochondrial membrane potential (Δψ), the sensitivity of mitochondrial(More)
Monoamine oxidases (MAOs) have recently emerged as important mitochondrial sources of oxidative stress in the cardiovascular system. Generation of reactive oxygen species during the brief episodes of ischemic preconditioning (IPC) is responsible for the cardioprotection at reperfusion. The aim of this study was to assess the effects of two MAO inhibitors(More)
Orotic acid and its salts chronically administered have been shown to significantly improve cardiac function in pathological settings associated with ischemia-reperfusion (I/R) injury. The aim of our study was to investigate the effect of magnesium orotate (Mg-Or) administration at the onset of post-ischemic reperfusion on myocardial function and infarct(More)
AIM Monoamine oxidases (MAOs) are mitochondrial enzymes, with 2 isoforms, A and B that convert biogenic amines to their corresponding aldehydes via a reaction that produces hydrogen peroxide. Since MAO-A is the predominant form at vascular level we hypothesized that MAO-A-dependent H2O2 production may contribute to the development of endothelial dysfunction(More)
