Succinic dehydrogcnase (SDH) was localized in the mitochondria of Sarcoma 37 ascites tumor cells by the use of tetranitro-BT (TNBT) and nitro-BT (NBT) in smear preparations. Results with each tetrazolium salt as electron acceptor wcrc evaluated with respect to: (a) size and shape of the formazan precipitate relative to standard mitochondrial morphology; (b) crystallization phenomena of reduced ...

Jan Samuelsson, MD, PhD, Department of Medicine, Section for Hematology, Karolinska Institute at Stockholm Söder Hospital, S-118 83 Stockholm (Sweden) We read with interest the report by Piva et al. [1] describing an impaired function of the NADPH oxidase, assessed as the reduction of nitroblue tetrazolium (NBT) after stimulation with phorbol myristate acetate (PMA), in patients with various st...

INTRODUCTION Leukocytes play a key role in maintaining the balance between an effective host defence response to microorganisms and periodontal tissue destruction. Neutrophil dysfunction has been associated with increased susceptibility to periodontal diseases. We undertook this study to determine to what extent neutrophil dysfunction constitutes to the pathogenesis of aggressive periodontitis ...

UNLABELLED Experimental data have demonstrated that impaired antioxidant capacity is associated with increased levels of reactive oxygen species (ROS) production. ROS can cause inactivation of critical enzymes and induce denaturation that renders proteins nonfunctional. Total blood is continuously exposed to oxidative stress. The aim of the current study was to investigate the reduction of nitr...

PURPOSE The aim of this study was to retrospectively observe and analyze the long-term treatment outcomes of a total of 140 esophageal cancer patients who were treated with californium-252 ((252)Cf) neutron brachytherapy (NBT) in combination with external beam radiotherapy (EBRT) and concurrent chemotherapy (CCT). METHODS AND MATERIALS From January 2002 to November 2012, 140 patients with eso...

C-CAM is a Ca(2+)-independent cell adhesion molecule (CAM) that mediates intercellular adhesion of isolated rat hepatocytes. It is widely distributed in epithelia, where its presence both at lateral cell borders and on apical cell surfaces suggests that it may have diverse biological functions. Two major isoforms, C-CAM1 and C-CAM2, which differ in the lengths of their cytoplasmic domains, have...

Introducción. El nitrógeno (N) es el macronutriente que más afecta rendimiento de los cultivos; sin embargo, su utilización por cultivos se asocia a una baja eficiencia recuperación; esta razón necesario analizar absorción en tejido vegetal durante ciclo para obtener beneficio deseado. Objetivo. Conocer efecto la fertilización nitrogenada crecimiento, concentración nitratos base del tallo (NBT)...
