platelet activation and adhesion to the site of vascular injury is a dynamic process comprising reversible and irreversible phases. platelet adhesion typically occurs in a multi-step process similar to the selectin/integrin-mediated adhesion of neutrophils. this phenomenon is highly regulated and influenced by the cross-talk between platelets and injured endothelium. this cross-talk involves a ...

We introduce the notion ofstrongly $alpha$-reversible rings which is a strong version of$alpha$-reversible rings, and investigate its properties. We firstgive an example to show that strongly reversible rings need not bestrongly $alpha$-reversible. We next argue about the strong$alpha$-reversibility of some kinds of extensions. A number ofproperties of this version are established. It is shown ...

This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...

an octahedral cobalt(iii) complex, trans-[(me2bpb)co(bzlan)2]clo4 (1), with h2me2bpb = n,n’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, ir, uv-vis, and 1h nmr spectroscopy. the structure of this complex has been determined by x-ray crystallography. the me2bpb2– is a di-anionic tetradentate ligand furnishing a ...

PbO nanoparticles were synthesized using hydrothermal process. Scanning electron microscopy (SEM) was used in order to investigate of PbO powders. X-ray diffraction (XRD) pattern confirmed β-PbO formation during this process. The crystallite size of the powders was calculated using Scherrer formula about 74.6 nm. Electrochemical evaluation of the PbO nanoparticles as anode for Li-ion batteries ...

Cells are active components in their environment and constantly adjusting their performance to improve extracellular milieu changing. This approach is reflected their tends of maintaining intracellular homeostasis. When the cells encounter stress or pathologic stimuli, they can undergo a new manner (adaptation) and new steady state for achieving viability and function. If the external stress is...

Electrochemical behavior of I-hydroxypyridine-2-thione and its vanadium complex is studied using polarographic techniques. Polarograms of ligand and that of the complex is shown with diffusion characteristics of the waves. Cyclic voltagram of thione is investigated which shows that a reversible oxidation reduction of one electron process is taking place. PKa of the thione is found to be in ...
