Intact human red blood cells can synthesize FAD and FMN from riboflavin. The rate of synthesis of FAD is linearly proportional to the concentration of riboflavin in the medium at levels below 0.9 1 M. With 0.9 1 M riboflavin, the rate of synthesis is about 0.1 m mole FAD/ml. red blood cells/hour. Incubation of red blood cells with riboflavin can result in increased red cell glutathione reductas...

The effect of hyperosmotic solution of NaCl, urea and mannitol on Bufo viridis red blood cells were studied. The percentage of water content in B. viridis red blood cells decreased significantly in NaCl and mannitol hypertonic solutions compared to urea hypertonic solution. The urea concentration found in red blood cells in a urea hypertonic solution was significantly higher than in red blood c...

This study aims to survey the effects of a circuit resistance training session with a light intensity on some hematological parameters of male students of Physical Education. After the release of an announcement and call, 20 male students of Physical Education voluntarily participated in this study. After equalization, they were randomly divided into two groups including light-intensity exercis...

BACKGROUND DNA repair is a cellular defence mechanism responding to DNA damage caused in large part by oxidative stress. There is a controversy with regard to the effect of red blood cells on DNA damage and cellular response. AIM To investigate the effect of red blood cells on H2O2-induced DNA damage and repair in human peripheral blood mononuclear cells. METHODS DNA breaks were induced in ...

Introduction:   Mesenchymal stem cells have the potential of self-renewal and differentiation into different cell types, including blood cells, heart, nerves and cartilage, and have unlimited power for division. These cells can be obtained from cord, before implantation from fertilized cells and also from various tissues of adults although the differentiation power and the ability to reproduce ...

The present study was designed to analyse the effect of red blood cells on T-cell proliferation and expansion. A comparative study was done in peripheral blood cell cultures stimulated with phytohemagglutinin, with or without red blood cells. The presence of red blood cells had a consistent enhancing effect on T lymphocyte proliferation, as determined by an increase in both the mitotic index an...

The mechanism by which glutathione reductase (GR) activity is regulated in relation to fiavin metabolism was studied in red cells of normal adults, cord blood, and patients with severe metabolic disorders using spectrophotometnc, fluorometnc, and radiochemical methods. The increased activity of GR in red cells of adult patients with severe hepatic cirrhosis, chronic uremia, and glucose-6-phosph...
