The efficacy of iron therapy in nutritional anaemia, which has been shown to be of such common occurrence in infants and adults (Mackay"6; Faber6; Davidson et al'; Fullerton') is apparently dependent on the administration of large doses of iron if given orally (Heath"; Witts"). In this connection it is interesting to recall that the use of large doses was first advocated in 1832 by Blaud'. Only...
Two efficient and convenient procedures for the synthesis of 6-amino-3-methyl-1,4-diphenyl-1,4-dihydropyrano[2,3c]pyrazole-5-carbonitrile derivatives based on four-component reaction involving ethyl acetoacetate, phenylhydrazine, malononitrile, and various aromatic aldehydes using trichloroacetic acid or ceric sulfate as heterogeneous catalysts in excellent yields and short reaction times have ...
The mass ratio of nuclear non-histone protein: DNA in the immature circulating erythroid cells of phenylhydrazine-induced anaemic Xenopus is approximately threefold higher than in mature erythrocytes. This is largely due to the presence of increased amounts of low and intermediate molecular weight proteins in the nuclei of the immature cells. There are a few qualitative differences in the compo...
The aim of this study was to synthesize a new oxetan-phenyltetrahydropyridazine-3,6-dione derivative (compound 6) using with different techniques. The first method was achieved by the preparation of a phenylhydrazine derivative (2) using three components system (3,17-aldol-estradiol, phenylhydrazine, 5-hexyn-3-ol) in presence of Copper(II). Then, 2 Was reacted with tert-butyldimethylsilyl chlor...
A one-step reduction and functionalization of graphene oxide (FrGO) was easily achieved using a novel phenylhydrazine-based reductant containing fluorine atoms, which can induce p-type doping due to its high electronegativity. The FrGO-based OPV exhibited a high power conversion efficiency of ∼6.71% and a superior OPV-stability to commercial PEDOT:PSS.
labeled glycine, L-histidine, L-leucine, and L-lysine into the proteins of rabbit reticulocytes. In preliminary experiments the incorporation into the hemoglobin isolated from the reticulocytes was determined. But, after it was found that plasma contains factors accelerating amino acid incorporation, it was decided to proceed as rapidly as possible toward the identification of these factors; we...
Reticulocyte count is the salient evidence of effectiveness bone marrow to produce red blood cells. Currently, reticulocyte counting a challenge for clinical laboratoriesmainly ordinary ones, which still use manual method.This study was designed evaluate performance flow cytometer reticulocytes comparing traditional and optimized methods helpful in diagnosis phenylhydazine-induced anemia.For th...
