The paper reports electrical properties of human blood and plasma of belonging to different physiological and environmental conditions. Dielectric parameters such as dielectric constant, dielectric loss and electrical conductivity of human blood and plasma of groups A, B, AB and O are measured at the frequency of 1kHz using digital LCZ meter. It is found that the values of dielectric constant, ...

A new sensitive, selective and nonexpensive electrochemical sensor was developed for electrocatalyticdetermination of glutathione (GSH)in pharmaceutical and biological samples. GSH is a tripeptide thiol present in all eukaryotic and probiotic cells. A voltammetric studyof GSH has been carried out at the surface of carbon paste electrode modified with multiwall carbon nanotubes(MWCNTPE) in the p...

A glassy carbon electrode was modified with graphene oxide nanosheets and a hybrid of copper-cobalt hexacyanoferrate. The nanocomposite was characterized by cyclic voltammetry, FT-IR and scanning electron microscopy. Cyclic voltammetry showed a stable and reversible redox pair with surface confined characteristics in phosphate buffer solution (0.1 M, pH 3). Hydrodynamic amperometry was used for...

Carbonic anhydrase (CA) was purified from bovine erythrocyte plasma membrane and characterized in this study. For this purpose, the blood taken from young animals was hemolysed, the membrane fraction was separated, and this fraction was repeatedly washed. The enzyme (CA) was removed from the membrane with buffered TritonX-100 (1%); it could be purified at a factor of 22.8 by affinity chromatogr...

INTRODUCTION There are a number of pre-analytical and analytical factors, which cause false results in the complete blood count. The present case identifies cold agglutinins as the cause for the mismatch between hematocrit and hemoglobin values. MATERIALS AND METHODS 70-year old female patient had a history of cerebrovascular diseases and rheumatoid arthritis. During routine laboratory examin...

Pentoxifylline increases erythrocyte flexibility, reduces blood viscosity,and inhibits platelet aggregation and is thus used in the treatment of peripheral vasculardisease. It is transformed into at least seven phase I metabolites, of which two, M1 andM5, are active. The reduction of the keto group of pentoxifylline to a secondary alcoholin M1 takes place chiefly in erythrocytes...
