Umbilical cord blood collected from the postpartum placenta and cord is a rich source of hematopoietic stem cells (HSCs) and is an alternative to bone marrow transplantation. In this review we wanted to describe the differences (in phenotype, cytokine production, quantity and quality of cells) between stem cells from umbilical cord blood, bone marrow and(More)
Total parenteral nutrition (TPN) is essential for patients with postoperative impairing gastrointestinal function who are unable to receive and absorb oral/enteral feeding for at least 7 days. Oxidative stress plays a major role in the ethiopathogenesis of cancers. In this study, total antioxidant status (TAS), glutathione peroxidase (GPx), superoxide(More)
Objective Our objective was to evaluate the state of oxidative stress in the great saphenous varicose vein wall and blood of varicose vein patients taken from the antecubital vein. Methods The superoxide dismutase, reduced glutathione (GSH) and total antioxidant status were measured with commercially available colorimetric kits in erythrocytes, plasma and(More)
OBJECTIVE Gelatinases, Matrix MetalloProteinase(MMP)-2 and MMP-9, belong to zinc-dependent endopeptidases involved in several physiological and pathological processes including inflammation and tumor development. Because the information about the involvement of gelatinases in pituitary adenoma (PA) development are scant, our objective was the analysis of(More)
BACKGROUND Nitric oxide (NO) is synthesized by the conversion of Arginine (Arg) into the NO and Citrulline (Cit). Although the NO is involved into the pathogenesis of several physiological and pathological processes, the role of NO in pituitary adenomas (PA) progres-sion is not determined. Our purpose was to evaluate the relationship between NO and PA as(More)
