In recent years, determining the common information privately and efficiently between two mutually mistrusting parties have become an important issue in social networks. Many Private set intersection (PSI) protocols have been introduced to address this issue. By applying these protocols, two parties can compute the intersection between their sets without disclosing any information about compone...

A physiological strain index (PSI) based on rectal temperature (Tre) and heart rate (HR) was recently suggested to evaluate exercise-heat stress. The purpose of this study was to evaluate PSI for gender differences under various combinations of exercise intensity and climate. Two groups of eight men each were formed according to maximal rate of O2 consumption (V˙o 2 max). The first group of men...

We prepared the poly(succinimide) (hereafter abbreviated as PSI) microcapsules with antitumor agent showing a pH-responsive release. PSI microcapsules enclosing Irinotecan hydrochloride (CPT-11) were prepared by solvent evaporation method via O/O emulsion system. The obtained PSI microcapsules had a smooth surface and were spherical with diameter of approximately 30 μm. CPT-11 was successfully ...

Continuous flow systems for hydrogenation using polysilane-supported palladium/alumina (Pd/(PSi-Al(2)O(3))) hybrid catalysts were developed. Our original Pd/(PSi-Al(2)O(3)) catalysts were used successfully in these systems and the hydrogenation of unsaturated C-C bonds and a nitro group, deprotection of a carbobenzyloxy (Cbz) group, and a dehalogenation reaction proceeded smoothly. The catalyst...

Increase in extracellular Mg2+ concentration ([Mg2+]o) reduces Ca2+ accumulation during reoxygenation of hypoxic cardiomyocytes and exerts protective effects. The aims of the present study were to investigate the effect of increased [Mg(2+)](o) on Ca2+ influx and efflux, free cytosolic Ca2+ ([Ca2+]i) and Mg2+ concentrations ([Mg2+]i), Ca2+ accumulation in the presence of inhibitors of mitochond...

Membrane surface electrostatic interactions impose structural constraints on imported proteins. An unprecedented sensitive dependence on these constraints was seen in the voltage-gated import and channel formation by the C-terminal pore-forming domain of the bacteriocin, colicin E1. At physiological ionic strengths, significant channel current was observed only in a narrow interval of anionic l...

We have used the nonionic detergent octyl-O-D-glucopyranoside in combination with sodium dodecyl sulfate to isolate two novel Photosystem I (PSI) complexes from spinach (Spinacea oleracea L.) thylakoid membranes. These complexes have been characterized as to their spectral properties, content of PSI reaction center chlorophyll P7-, and protein composition. PSI-B, purified from solubilized membr...

Relapse of neuroblastoma (NB) commonly occurs in hypoxic tissues. Buthionine sulfoximine (BSO), an inhibitor of glutathione (GSH) synthesis, is cytotoxic for NB cell lines in atmospheric oxygen (20% O(2)). Tirapazamine (TPZ) is a bioreductive agent that forms a toxic-free radical in hypoxia. We determined in four NB cell lines cytotoxicity using the DIMSCAN digital imaging fluorescence assay, g...
