Some Biochemical and Electrophoretic Studies on Purified Prothrombin , Factor VII (
S TUDIES of the chemical nature of prothrombin have indicated a glycoprotein structure.2 Data obtained on purified bovine prothrombin have shown the reducing sugar content to be approximately 5 per cent, based on a reference standard of galactose and mannose.35 Laki et al.5 reported a value of 6.5 per cent in terms of glucose, and 1.6 to 1.7 per cent hexosamine. Alexander6 and colleagues observ...
متن کاملKinetic Studies of Some Free Radical Reactions
Kinetic and mechanistic studies on some characteristic freeradica1 reactions are reviewed briefly. The unimolecular rearrangements: RCMe2CH ÷ Me2CCH2R, fall into two classes. Class 1: R = R'C(O)O for which the 1,2—migration occurs via a 5—eenter cyclic transition state with considerable charge separation, [R'C02 Me2CCH2]*. Class 2: R = H2C=CH, Me3CC=0, C6H5, Me3CCsC, and CsN, for which migratio...
متن کاملStudies of Transport in Some Oxides by Gas Phase Analysis
The effects of porous Pt on the oxidation of Cr at 800°C have been studied by Gas Phase Analysis (GPA), Secondary Ion Mass Spectrometry (SIMS) and X-ray Photoelectron Spectroscopy (XPS). In the oxide areas with Pt, a substantial oxide growth near the Cr substrate takes place by a pronounced inward oxygen transport. Oxide grown on areas without Pt, the SIMS counts of CrO ions depend on the dista...
متن کاملReductive Coupling Reactions of Nitrones and Imines, Modern Versions
INTRODUCTION Pinacol coupling was first described by Fittig in 1859, when he reported the formation of 2,3dimethyl-2,3-butanediol (1) from acetone and sodium metal. Since then, this ketyl radical anion coupling process has undergone significant advancement, including the development of asymmetric variants. 3 Alternatives to use of strong reducing metals are low valent transition metals and lant...

6. Urinary tract infections.?In acute cystitis and pyelitis and in chronic infection due to coli bacilli sulphanilamide is adequate but sulphacetamide has been particularly recommended because of its high solubility in urine. Its sodium salt (albucid soluble) may be injected intravenously in 30 per cent solution. Sulphathiazole or sulphadiazine may be given in resistant cases. The average daily...
