BACKGROUND Following kidney transplantation, ischemia-reperfusion injury contributes to adverse outcomes. The purpose of this study was to determine whether a cold-storage solution saturated with noble gas (xenon or argon) could limit ischemia-reperfusion injury following cold ischemia. METHODS Sixty Wistar rats were randomly allocated to 4 experimental groups. Kidneys were harvested and then...

The thermoelectric properties of several materials with the skutterudite structure have been investigated at the Jet Propulsion Laboratory (JPL). Based on literature data and experimental findings at JPL, semiconductors with the skutterudite structure have interesting transport properties and show a good potential for high ZT values. A large number of binary and ternary compounds, solid solutio...

Abstract A molecular dynamics model is created for argon near the critical point. As temperature falls at a constant density less than critical, It established that drop of liquid forms in gas environment. This not spherical, but cylindrical. Liquid melting point (110 K, 1.513 g/cm 3 ) also modeled. The values Voronoi polyhedra volumes (VPVs) around atoms are calculated and their distribution p...

OBJECTIVE This study was designed to evaluate the effect of argon laser irradiation on development and progress of enamel demineralization around orthodontic brackets. MATERIALS AND METHODS Fifty caries-free, intact human premolars were randomly assigned to one of the following five equal groups: Groups 1 (control) and 2: The brackets were bonded using conventional halogen light for 40s and a...

Time resolved atomic emission, atomic absorbance, and laser-induced atomic fluorescence measurements of a Ž3 . millisecond pulsed glow discharge, made perpendicular to the insertion probe, provide temporal profiles of 1s P 5 2 Ž3 . and 1s P metastable argon atom populations. Acquisition of these profiles at different spatial positions in the 3 0 plasma provides data from which two-dimensional s...

General considerations. All manipulations of air-sensitive compounds were performed using standard Schlenk techniques under argon atmosphere. NMR spectra were recorded with either a Bruker ARX 300, Bruker Avance DRX 600 or Varian INOVA-400 spectrometer. H and C NMR chemical shifts were referenced to H and C NMR signals of the deuterated solvents, respectively. High temperature NMR measurements ...

PURPOSE To describe the use of argon laser iridoplasty following implantation of a multifocal intraocular lens (IOL) to improve visual function. METHODS Argon laser spots of 500-mW power, 500-μm spot diameter, and 500-ms duration were placed in the midperipheral iris in the area in which the iris was encroaching on the IOL. RESULTS Argon laser iridoplasty provided statistically significant ...
