Thermoelasticity of red blood cell membrane

Thermoelasticity of red blood cell membrane.

The elastic properties of the human red blood cell membrane have been measured as functions of temperature. The area compressibility modulus and the elastic shear modulus, which together characterize the surface elastic behavior of the membrane, have been measured over the temperature range of 2-50 degrees C with micropipette aspiration of flaccid and osmotically swollen red cells. In addition,...

Phosphorylation of the Red Blood Cell Membrane

The phosphorylation of red blood cell membrane fragments (RBCMF) during Ca ++ transport was investigated. When red cell membrane fragments are incubated with [y-a2P]ATP under the experimental condition which minimizes the phosphorylation of Na+-K+-ATPase, RBCMF are labeled in the presence of Mg ++ without Ca ++. When Ca ++ is added, the labeling decreases due to dephosphorylation of RBCMF. The ...

Effect of Thyroid Dysfunctions on Blood Cell Count and Red Blood Cell Indice

Abstract Background Thyroid hormones have a crucial role in metabolism and proliferation of blood cells. Thyroid dysfunction induces different effects on blood cells such as anemia, erythrocytosis leukopenia, thrombocytopenia, and in rare cases causes’ pancytopenia. It also alter RBC indices include MCV, MCH, MCHC and RDW. Thus this study attempted to evaluate effect of hypo & hyperthyroi...

Role of the phosphorylation of red blood cell membrane proteins.

The red blood cell membrane is composed of a lipid bilayer and two types of proteins: the integral proteins, which extend all the way across the lipid bilayer, and the proteins which do not penetrate the lipid bilayer and for this reason are called external proteins. The most important external proteins make up the membrane skeleton on which depend the membrane stability and the shape and defor...
