Mobilization of intracellular Ca(2+) stores regulates a multitude of cellular functions, but the role of intracellular Ca(2+) release via the ryanodine receptor (RyR) in the brain remains incompletely understood. We found that nitric oxide (NO) directly activates RyRs, which induce Ca(2+) release from intracellular stores of central neurons, and thereby promote prolonged Ca(2+) signalling in th...

Nitric oxide (NO) is a typical gaseous messenger involved in a wide range of biological processes. In our classical knowledge, effects of NO are largely achieved by activation of soluble guanylyl cyclase to form cyclic guanosine-3', 5'-monophosphate. However, emerging evidences have suggested another signaling mechanism mediated by NO: "S-nitrosylation" of target proteins. S-nitrosylation is a ...

The aim of the study was to compare the connective tissue response of Lewis rats to Ti, NiCr and AgPd alloys. It was found that implants were covered by collagen-rich, well vascularized capsules. Titanium was covered by the thinnest capsule (57 ± 20 μm) and AgPd alloy was covered by the thickest capsule (239 ± 50 μm). The PCNA+ cell prevalence in the capsules was lower for titanium than for AgP...

This study presents experimental and computational analyses of the phase composition mechanical behavior a functionally graded material (FGM) grading from 100 vol% 304L stainless steel (SS304L) to Ni-20Cr (NiCr) in 10 increments. The FGM was evaluated by extracting tensile specimens SS304L-rich NiCr-rich regions FGM, with former behaving ductile manner latter being relatively brittle. brittle r...

The aim of the present work is to evaluate activation energy (Ea) at different cathodic overpotentials (η) by potentiodynamic tests which were carried out temperatures Ni-based, NiCr-m, and NiCr-p porous electrodes, during alkaline electrolysis processes. On other hand, electrochemical stability electrodes was evaluated cyclic voltammetry after 1000 cycles operation potentiostatic 10 h −1.5 V v...
