Effects of carbon disulphide (CS2) on conduction velocity in sciatic and tibial nerve were investigated in rats exposed to CS2 vapour at concentrations of 0.9 mg/l or 1.6 mg/l of air for periods of 1.5, 3, 6, 9 and 12 months. The conduction velocity was measured on the day following each exposure period, and again, three and six months after the last day of exposure. The majority of exposed rat...

An octahedral cobalt(III) complex, trans-[(Me2bpb)Co(bzlan)2]ClO4 (1), with H2Me2bpb = N,N’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis, and 1H NMR spectroscopy. The structure of this complex has been determined by X-ray crystallography. The Me2bpb2– is a di-anionic tetradentate ligand furnishing a ...

this study intended to assess the efficacy of acute administration of natural honey on cardiac arrhythmias and infarct size when it is used during the normothermic ischemia in isolated rat heart. during 30 min of regional normothermic ischemia followed by 120 min of reperfusion, the isolated hearts were perfused by a modified drug free krebs-henseleit solution (control) or the solution containi...

objective(s) this study aimed to examine whether acetyl-l-carnitine (alc) was able to reduce cardiac arrhythmias and infarct size in the ischemic-reperfused isolated rat heart. materials and methods the isolated hearts were mounted on a langendorff apparatus then perfused by a modified krebs-henseleit solution during 30 min regional ischemia and 120 min reperfusion (control) or by enriched kreb...

A critical analysis of the feasibility of reversible computing is performed. The key question is: Is it possible to build a completely reversible computer? A closer look into the internal aspects of the reversible computing as well as the external constraints such as the second law of thermodynamics has demonstrated that several difficulties would have to be solved before reversible computer is...
