Peroxynitrite, the reactive species formed in vivo by the reaction of nitric oxide with superoxide anion, is capable of diffusing across erythrocyte membranes via anion channels and passive diffusion (A. Denicola, J. M. Souza, and R. Radi, Proc. Natl. Acad. Sci. USA 95, 3566-3571, 1998). However, peroxynitrite diffusion could be limited by extracellular targets, with the reaction with CO(2) (k(...

Changes in the oxygenation properties and the relevant biochemical parameters of canine blood were followed during its storage in acid-citrate-dextrose (ACD) medium (4 degrees C) and after transfusion of the stored blood. Reductions of the blood P50 (pH 7.40, PCO2 40 Torr, 37 degrees C) and 2,3-diphosphoglycerate (DPG) during storage was much slower than in human blood. Half-decay time for DPG ...

In this paper CuFe2O4, nanocrystalline powders were prepared. Also, the supported Cu ferrite was obtained by impregnation of the supports with Cu and Fe nitrates solutions, for calcination temperature 450 ºC. The samples were characterized by X-ray powder diffraction (XRD) and Fourier transform-infrared spectroscopy (FT-IR). In this investigation photocatalytic degradation...

Tulip is one of the most important flowers to precocity. Treatment of tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse resulting energy saving and reduces the tulip’s physiological disorders. This study carried out about three tulip cultivars includes ‘Lacourtine’, ‘Yokohama’ and ‘Red Favourite’. The results showed that gibberellic acid reduced significantly stem l...

Clenbuterol, a β2-adrenergic agonist, reduces mitochondrial content and enzyme activities in skeletal muscle, but the mechanism involved has yet to be identified. We examined whether clenbuterol-induced changes in the muscles' metabolic profile and the intrinsic capacity of mitochondria to oxidize substrates are associated with reductions in the nuclear receptor coactivator PGC-1 alpha and/or a...

exist for cholinesterase assay, but each has drawbacks (1, 2). This paper presents an improved version of Garry and Routh's modification (3) of Ellman's method, as well as variations of this method for the assay of " true " cholinesterase in red cells and for the determination of the dibucaine number. The basic reactions are: Milwaukee, Wis. 53233), 2.0 mg/mI in 0.2 molar potassium phosphate bu...
