The cGMP-gated cation channel mediating visual transduction in retinal rods was recently found to comprise at least two subunits, 1 and 2 (or alpha and beta). SDS gels of the purified channel show, in addition to a 63-kDa protein band (subunit 1), a 240-kDa protein band that binds Ca(2+)-calmodulin, a modulator of the channel. To examine any connection between subunit 2 and the 240-kDa protein,...
We have reported the linear relation of myocardial oxygen consumption per beat (VO(2)) and systolic pressure-volume area (PVA) in the left ventricle of the cross-circulated rat heart. The VO(2) intercept (PVA-independent VO(2)) is primarily composed of VO(2) for Ca(2+) handling in excitation-contraction coupling and basal metabolism. Recently, we proposed a new index for oxygen cost of contract...
BACKGROUND Healthcare-associated (HCA) infection has emerged as a new epidemiological category. The aim of this study was to evaluate the impact of HCA infection on mortality in community-onset Klebsiella pneumoniae bloodstream infection (KpBSI). METHODS We conducted a retrospective study in two tertiary-care hospitals over a 6-year period. All adult patients with KpBSI within 48 hours of adm...
The purpose of this study was to investigate the response of physicochemical properties of gerbera (Gerbera Jamesonii L.) to silica nanoparticles (Nanoparticle-SiO2) and calcium chelate (Ca-Chelate) in nutrient solutions. A factorial experiment based on completely randomized design with two factors was conducted in four replicates. The first factor the concentration of Nanoparticle-SiO2 in nutr...
Disturbed sarcoplasmic reticulum (SR) Ca content may underlie the altered force-frequency and postrest contractile behavior in failing human myocardium. We used rapid cooling contractures (RCCs) to assess SR Ca content in ventricular muscle strips isolated from nonfailing and end-stage failing human hearts. With an increase in rest intervals (1 to 240 s; 37°C), nonfailing human myocardium (n57)...
Calcium borohydride hydrazinates, Ca(BH4)2-nN2H4 (n 1⁄4 4/3, 1, 2, 3) have been synthesized successfully. In particular, Ca(BH4)2 2N2H4 crystallizes in a monoclinic space group of C2/m with the lattice parameters of a 1⁄4 10.1385 Å, b 1⁄4 8.6342 Å, c 1⁄4 4.6384 Å, b 1⁄4 106.467 . It can release 5.9 equiv. gas/Ca(BH4)2 (approximately 8.8 wt. % H2) at 240 C. Ca(BH4)2-N2H4 and Ca(BH4)2-4/3N2H4, on...
Sewage sludge at the rate of 0, 40, 80, 120 and 240 t/ha showed that the number of filled grains per panicle, dry weight of grains and weight of 1000 grains of rice (Oryza sativa L.) were the significantly highest where 240 tons of sewage sludge per hectare was added. The contents of N, P, K, Ca, Mg, Fe, Cu, Zn and Pb in rice grains increased significantly with increasing rate of sewage sludge ...
