Oxygen-binding properties of single red blood cells from the red-eared turtle Trachemys scripta were measured by microspectrophotometry to describe the variation in oxygen affinity of red blood cells and to gain insight into the distribution of functionally different hemoglobins among red blood cells. Methodologically, this study represents the first report on the cell-to-cell variation in oxyg...
I T HAS been demonstrated by Fahraeus’4 that normal red blood cells have a tendency to bcccme spheroidal in shape after standing in vitro at body ternperature. G#{228}nsslen,5 Haden6 and Castle and Daland7 have shown that spheroidal red cells are more susceptible to osmotic hemolysis than are normal corpuscles. Haden found that normal red cells when suspended in graded hypotonic salt solutions ...
Background: Reticulocytes are immature red blood cells with RNA, spending the final stages of their maturation in the peripheral blood. The number of reticulocytes in the peripheral blood is the salient evidence of the effectiveness of bone marrow to produce red blood cells. Currently, reticulocyte count is done manually or automatically in clinical laboratories. Difficulties and limitations of...
Background In recent years, many researchers haveattempted to cure diabetes by using stem cells technology. Stem cells from different sources have capabilityto differentiateinto insulin producing cells (IPCs) by different methods. The obstaclesof these methods aretheirexpensive materials and complexity ofmethodswhichare practicallydisadvantagesfor producing enough transplantableIPCs that can ...
Background and Aim: Anemia is one of the major risk factors for cardiovascular disease (CVD) in hemodialyzed patients. Therefore, the present study was designed to investigate the effects of ω3 fatty acid supplement on anemia and hematologic factors in hemodialysis patients. Materials and Methods: The study was a double-blind randomized clinical trial on 34 hemodialysis patients. The patients ...
Background and purpose: The widespread use of silver nanoparticles in therapeutic and diagnostic methods has created some concerns. Different sizes and shapes of nanoparticles have different effects. In this investigation, toxic effects of spherical nanosilver with average diameter of 4 nm were investigated on MCH and HGB in male Wistar rats. Materials and methods: In this study, concentration...
Hypoxanthine catabolism in vivo is potentially dangerous as it fuels production of urate and, most importantly, hydrogen peroxide. However, it is unclear whether accumulation of intracellular and supernatant hypoxanthine in stored red blood cell units is clinically relevant for transfused recipients. Leukoreduced red blood cells from glucose-6-phosphate dehydrogenase-normal or -deficient human ...
K+ released from exercising muscle via K+ channels needs to be removed from the interstitium into the blood to maintain high muscle cell membrane potential and allow normal muscle contractility. Uptake by red blood cells has been discussed as one mechanism that would also serve to regulate red blood cell volume, which was found to be constant despite increased plasma osmolality and K+ concentra...
