Patch-clamp recordings were performed to study the effects of three calmodulin (CaM) antagonists on the gating of intermediate calcium-activated K + channels (IK Ca ) of human erythrocytes. In the cell-attached configuration, both opening frequency a

The in vivo function of the erythrocyte Na+–Li+ countertransport (SLC) is unknown. Whether SLC may reflect an operational mode of the widespread Na+–H+ exchanger (NHE) or may otherwise be expression of an independent membrane transport, remains p

Chromatography on a novel stationary phase, human red cells immobilized in a gel bed, was introduced for analysis of activities of the glucose transporter Glut1 in the cell membrane. A gel containing positively charged ligands was synthesized from de

Red blood cell (RBC) swelling and membrane hole formation in hypotonic external media were studied by measuring the time-dependent capacitance, C, and the conductance, G, in the beginning of the beta-dispersion range. At high and moderate osmolaritie

In the present study, we demonstrated the suitability of liposomes as a method of removing plasma bilirubin in hyperbilirubinemic rats. The liposomes have innate tendency to bind with bilirubin through hydrophobic interaction. Among different types o

Amphiphiles which induce either spiculated (echinocytic) or invaginated (stomatocytic) shapes in human erythrocytes, and ionophore A23187 plus Ca2+, were studied for their capacity to induce shape alterations, vesiculation and hemolysis in the morpho

The effects of temperature on the formation and inactivation of syringomycin E (SRE) pores were investigated with human red blood cells (RBCs) and lipid bilayer membranes (BLMs). SRE enhanced the RBC membrane permeability of 86Rb and monomeric hemogl

Tamoxifen (TAM), the antiestrogenic drug most widely prescribed in the chemotherapy of breast cancer, induces changes in normal discoid shape of erythrocytes and hemolytic anemia. This work evaluates the effects of TAM on isolated human erythrocytes,

The effect of ATP-depletion or its consequence, by metabolic inhibition, on the inhibition of glucose transport by various inhibitors was studied in human red cells. In cells depleted of ATP, glucose exit times were longer than in normal cells and th

The current study was designed to characterise K(+) transport in human fetal red blood cells, containing mainly haemoglobin F (HbF, and termed HbF cells), isolated from umbilical cords following normal parturition. Na(+)/K(+) pump activity was compar
