Association between Insulin and Nitric Oxide in Human Retinal Microvascular Endothelial Cells in vitro حسب Rizk, Nasser Moustafa

"…In conclusion, this study demonstrated that Hyperglycemia causes an increase in ROS/oxidative stress and apoptosis, while insulin promotes a significant decrease in ROS and apoptosis, eNOS mediated NO production increases with hyperglycemia but remarkably decreases with insulin treatment after 1 hour, 2 hours and 4 hours, insulin could counteract the hyperglycemic effect on AKT/pI3 kinase which mediates NO production and VEGF-A, decreased adhesion molecules p-selectin involved in barrier disorder of retinal endothelial cells. …"

Effect of hyperglycemia on EPCs function and regenerative ability حسب Hendawi, Hadeel Khalil

"…This research aims to test the EPC subtype blood outgrowth endothelial cells (BOECs) and their ability to survive and function under chronic hyperglycemic conditions. For that, we studied BOECs viability, response to shear stress, angiogenesis ability, and barrier function under normoglycemic (5.5mM) and hyperglycemic (25mM) conditions. …"

Superior photocatalytic activity of Cu doped NiWO4 for efficient degradation of benzene in air even under visible radiation حسب Tri N.L.M.

"…This was because Cu effectively acted as novel dopant, which not only affected valence band (VB) top and conduction band (CB) bottom of NiWO4 but also formed a medium energy level between CB and VB of the NiWO4 to decrease its energy band gap and electron-hole recombination rate. …"
