carvedilol is administered as a racemic mixture of the r(+)- and s(-)-enantiomers, although it was demonstrated that the two enantiomers exhibit different pharmacological effects and stereoselective pharmacokinetics. the aim of this study was the evaluation of several native and derivatized cyclodextrines as chiral selectors for the separation of carvedilol enantiomers. stereoselective interact...

abstract         background and objective: normal hemoglobin (hb) is formed of a heme group and a protein group known as globin. globin is made of four polypeptide chains and in hemoglobinopathies, the structure of one of these four polypeptide chain becomes abnormal. cellulose acetate method is a common way to differentiate haemoglobinopathies. inability to identify the components of hb low co...

this study was conducted to determine the electrophoretic pattern of serum protein in goats infected withbabesia ovis. serum total protein was calculated and serum electrophoresis from 15 goats naturally infectedwith b. ovis as well as same number of healthy goats was performed. microscopic examination of giemsastained peripheral blood smears revealed b. ovis infection. the parasitological diag...
