Isolated Bacillus strains BA1 and BA2 were a good source of amylase as they also showed high amylolytic activity. Both showed a clear zone on starch agar plate of 4.0 & 4.2mm in diameter respectively. The strain BA1 and BA2 produce amount of amylolytic enzyme 0.908μ/ml and 0.802μ/ml after the incubation of 24 hours at 37±2 0 C respectively. As the time of incubation increase the amylolytic acti...

As a cyan-emitting oxonitridosilicate phosphor, BaSi2O2N2:Eu2+ can be used as competent cyan compensator to improve the color rendering index of white light-emitting diodes (WLEDs). However, low luminescence efficiency and poor thermal stability this type phosphor seriously suppress its actual application in full-spectrum lighting. The replacements Ba2+ by Lu3+ Ba2+-Si4+ Lu3+-Al3+ greatly incre...

Abstract Two-Dimensional (2D) layered hybrid organic-inorganic perovskite (HOIP) materials have been considered as potential photoconductive for solar cells owing to extraordinary conversion efficiency and easy preparation process. In this study, we perform first-principles design on metal mixed 2D HOIPs (BA2(Cs1-xRbx)2Sn1.5Pb1.5I10 with different proportions of composition (x = 0, 0.5 1)) inve...

Cyclic nucleotides are known to modify voltage-gated (L-type) Ca2+ channel activity in vascular smooth muscle cells, but the exact mechanism(s) underlying these effects is not well defined. The purpose of the present study was to investigate the modulatory role of the cAMP- and cGMP-dependent protein kinase (PKA and PKG, respectively) pathways in Ca2+ channel function by using both conventional...

In this study the binding abilities of 1,3-calix[4]biscrown-6 (L) toward Ba2+ and Ca2+ have beenestablished in methanol by spectrophotometric measurements at 25±0.1 °C and 0.01 M ionicstrength, and with using Specfit computer program; stability constants for 2 : 1, metal : ligandcomplexes has been estimated

Using whole-cell recording in Drosophila S2 cells, we characterized a Ca(2+)-selective current that is activated by depletion of intracellular Ca2+ stores. Passive store depletion with a Ca(2+)-free pipette solution containing 12 mM BAPTA activated an inwardly rectifying Ca2+ current with a reversal potential >60 mV. Inward currents developed with a delay and reached a maximum of 20-50 pA at -1...

Outer hair cells (OHCs) are innervated by type II afferent fibers of as yet unknown function. It is still a matter of debate whether OHCs perform exocytosis. If so, they would require presynaptic Ca2+ channels at their basal poles where the type II fibers make contacts. Here we show that L-type Ca2+ channel currents (charge carrier, 10 mM Ba2+) present in neonatal OHCs [postnatal day 1 (P1) to ...

Store-operated Ca entry (SOCE) is thought to comprise the major pathway for Ca entry in platelets. Recently, a number of transient receptor potential (TRP) proteins, which have been divided into 3 groups (TRPC, TRPM, and TRPV), have been suggested as SOCE channels. We report the expression and function of TRPC proteins in human platelets. TRPC6 is found at high levels and TRPC1 at low levels. U...
