Increased production of superoxide anion may contribute to impaired bioactivity of endothelium-derived nitric oxide in hypertension. Ascorbic acid is capable of scavenging superoxide anion; however, experimental studies have shown that high physiological concentrations (.1 mmol/L) of ascorbic acid are required to prevent superoxide-mediated vascular dysfunction. To seek kinetic evidence that su...
BACKGROUND The mechanism of hypoxic pulmonary vasoconstriction (HPV) is still debatable. It has been proposed that reactive oxygen species (ROS) might be involved in HPV. However, there is no special transporter for superoxide anion in the cell membrane and it may release from the cells via anion exchanger. Therefore, the aim of this study was to investigate the interaction of ROS and anion exc...
Review: Synthesis, Characterization and Studies on Controlled Release Properties of Layered Compound
Layered inorganic structure such as Double Hydroxide (LDH), zinc layered hydroxide (ZLH) and graphene, in nano-size, have been used widely the nanotechnology areas a new promising problem solving materials. The ability of these compounds that able to encapsulate organic anions were known provide greatest benefits; explained more details this paper. Intercalations anion into interlayer spaces an...
Introduction: Perepubertal varicocele can result in hypotrophy of testes, sperm damage and decrease the function of leydig cells in future. pathophysiology of varicocele is unclear. Increased reactive oxygen species (ROS) is a major theory. There are many controversies in treatment of pediatric varicocele. Flaxseed (FS) is the richest source of lignans with antioxidant properties. The aim of...
