One element believed to be activated by ROS and to contribute to the reduction of ROS production, is the uncoupling protein-2 (UCP2). The objective of this investigation was to explore the effect of myocardial ischemia reperfusion on cardiac UC...

Introduction: Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-2 (Nox2) is one of the predominant sources of ROS production during myocardial ischemia-reperfusion and can be induced by angiotensin II. The evidence suggests that pharmacological blockers of renin-angiotensin system can exert direct tissue effects independent of their ability to regulate blood pressure. The mechanism...
Planning, construction and assessment of road network are among the investigations for infrastructure development at watershed scales. The main aim of this study is assessing the road network connectivity in the Chehel-Chay Watershed, located in Golestan Province using Alpha (α), Beta (β), Gamma (γ), Eta (η), network density and detour indices in graph theory. The available road network ma...
