The mechanisms that bring galaxies to strongly reduce their star formation activity (star-formation quenching) is still poorly understood. To better study galaxy evolution, we propose a classification based on the maps of ionised hydrogen distribution, traced by kpc-resolved, equivalent width H$\alpha$ maps, and nuclear using information from BPT diagnostic diagrams. Using these tools, group sa...

introduction: cigarette smoking affects nitric oxide production. the aim of this study was to determine associations between tobacco smoke and serum nitric oxide metabolites (nox) concentration. methods: serum nox concentration was measured by the griess method in 230 nonsmokers, 238 active, 196 passive and 29 waterpipe smokers. subjects were selected from participants of tehran lipid and gluco...

Fish larvae experience major cellular and biochemical changes during their early life stages.The aim of the present study was to evaluate alterations in the antioxidant status and values oflipid peroxidation and vitamin C content during the different life developmental stages ofHypophthalmichthys molitrix. Eggs and larvae were sampled at fertilization, organogenesis,eyed egg, hatch, active feed...

Recently, matrix metalloproteinases (MMP), in particular the gelatinases MMP-2 and MMP-9, generally considered as tumor markers for clinical applications. A longitudinal 2-years follow-up survey was performed on dogs with cutaneous tumor. Serum samples were obtained from 22 dogs with different cutaneous tumors and 22 health dogs at the time of surgery and one month, three months and one year af...
