Aerobic exercise confers sustainable protection against cardiac hypertrophy and heart failure (HF). Nitric oxide synthase (NOS) and nitric oxide (NO) are known to play an important role in exercise-mediated cardioprotection, but the mechanism of NOS/NO stimulation during exercise remains unclear. The aim of this study is to determine the role of β3-adrenergic receptors (β3-ARs), NOS activation,...
Distribution profiles of superoxide dismutase isoenzymes in various tissues of rabbits with the Vx-2 carcinoma in the maxillary sinus were compared with those of control rabbits. Copper- and zinc-containing superoxide dismutase (Cu,Zn-SOD) activity in the liver of rabbits decreased significantly 3 weeks after transplantation. Manganese-containing superoxide dismutase (Mn-SOD) activity did not d...
OBJECTIVE To investigate the association of endothelial nitric oxide synthase (NOS), inducible NOS, manganese superoxide dismutase (SOD), and extracellular SOD gene polymorphisms with susceptibility to Behçet disease (BD) in Japan. METHODS Seventy-eight consecutive Japanese patients with BD and 107 healthy control subjects were genotyped by polymerase chain reaction or polymerase chain reacti...
BACKGROUND The function of endothelial progenitor cells (EPCs), which are key cells in vascular repair, is impaired in diabetes mellitus. Nitric oxide (NO) and reactive oxygen species can regulate EPC functions. EPCs tolerate oxidative stress by upregulating superoxide dismutase (SOD), the enzyme that neutralizes superoxide anion (O2-). Therefore, we investigated the roles of NO and SOD in gluc...
The effect of nano silica (50 mL L−1) and melatonin (75 µM) individually or in combination foliar applications on the morphophysiological, biochemical yield properties pea plants under salinity stress conditions was evaluated. Salt caused a remarkable decrease growth characteristics; for example, plant dry weight, height, number flowers plant−1, pods weight 100 green seeds protein concentration...
Congenital cardiac defects associated with increased pulmonary blood flow (Q(p)) produce pulmonary hypertension. We have previously reported attenuated endothelium-dependent relaxations in pulmonary arteries (PA) isolated from lambs with increased Q(p) and pulmonary hypertension. To better characterize the vascular alterations in the nitric oxide-superoxide system, 12 fetal lambs underwent in u...
one of the soil and water management practices in order to delay drought stress under water deficit condition; is superabsorbent application. in order to study the effect of superabsorbent application on yield and yield components, two antioxidant enzymes activity and water relation of two canola hybrids under terminal drought stress condition, a research was carried out in ahvaz climate condi...
Isolated copper/zinc superoxide dismutase (Cu/Zn-SOD) or manganese superoxide dismutase (Mn-SOD) together with hydrogen peroxide (H(2)O(2)) caused rapid breakdown of nitric oxide (NO) and production of peroxynitrite (ONOO(-)) indicated by the oxidation of dihydrorhodamine-1,2,3 (DHR) to rhodamine-1,2,3. The breakdown of NO by this reaction was inhibited by cyanide (CN(-)) or by diethyldithiocar...
