Metal oxides and sulfides are considered as one of interesting class of ceramics due to their versatile applications [1-5]. Zinc sulfide (ZnS) and barium oxide (BaO) gain attention among the researchers due to their unique optical and electrical properties and wide applications in electrical industries. ZnS exist as zinc blend structure (wurtzite crystal structure), whereas BaO exists as rock s...
Objectives—Inward rectifier K currents (Kir) determine the resting membrane potential and thereby modulate essential Ca -dependent pathways, like cell growth and synthesis of vasoactive agents in endothelial cells. Basic fibroblast growth factor (bFGF) acts as a vasodilatator and angiogenic factor. Therefore, we investigated the effect of bFGF on Kir and assessed the role in proliferation and n...
In reducing the high operating temperatures (≥800 °C) of solid-oxide fuel cells, use of protonic ceramics as an alternative electrolyte material is attractive due to their high conductivity and low activation energy in a low-temperature regime (≤600 °C). Among many protonic ceramics, yttrium-doped barium zirconate has attracted attention due to its excellent chemical stability, which is the mai...
OBJECTIVE To investigate the possible involvement of inward rectifying K(+) channels (K(IR)) in the response of human resistance vessels to bradykinin in vivo. METHODS AND RESULTS Drugs were administered via the brachial artery in healthy male volunteers and forearm blood flow was measured by venous occlusion plethysmography. Inhibition of K(IR) by barium chloride (4 micromol min(-1)) alone o...
OBJECTIVE Inward rectifier K+ currents (K(ir)) determine the resting membrane potential and thereby modulate essential Ca2+-dependent pathways, like cell growth and synthesis of vasoactive agents in endothelial cells. Basic fibroblast growth factor (bFGF) acts as a vasodilatator and angiogenic factor. Therefore, we investigated the effect of bFGF on K(ir) and assessed the role in proliferation ...
