Characteristics of sodium transport through the amiloride-sensitive sodium-magnesium pathway in hamster red cells
In hamster red cells, amiloride-sensitive Na influx, 0.8 mmol/l cell/hr, is the only, carrier-mediated, Mg-dependent pathway for inward Na transport. This Na-dependent Mg transport is involved in the regulation of intracellular Mg$\sp{2+}$ concentration under physiological conditions.

Elevated levels of low molecular weight substances in the red cells of some mammalian species imply unsuspected antioxidant strategies
… thesis) of curious metabolic anomalies in the red cells of black rhinoceros, and in particular a high free tyrosine level, suggested that a range of unusual, but presumeably physiological, processes might be found in mammalian red blood cells. As a follow-up to this, low molecular weight …

Amiloride-sensitive components of sodium transport in guinea pig red blood cells: A cause of imbalance of sodium ion at low temperature
… has previously been found that gaining of Na in red cells of guinea pig is faster than in those of ground squirrel during cold storage at 5$\sp\circ$C in vitro and amiloride can partially inhibit the accumulation. Also, amiloride-sensitive Na influx in guinea pig red cells is known to be larger …

Homeostasis and volume regulation in the Plasmodium falciparum infected red blood cell
… homeostasis of Plasmodium falciparum infected red blood cells, namely how infected cells retain their integrity for the duration of the parasite asexual reproduction cycle. The volume and shape changes of infected cells were measured and characterized at femtolitre resolution throughout the …

Forces on a wall-bound leukocyte due to flowing red blood cells
As part of the inflammation response, white blood cells (leukocytes) bind nearly statically to blood vessel walls before they transmigrate through the endothelium and exit the vessel. The inter-cellular interactions between the wall-adhered leukocyte and flowing red blood cells (erythrocytes) play …

Interactions between integral membrane proteins and the cytoskeleton in red blood cells studied by measured molecular lateral diffusion
… system. The model system chosen was the red blood cell membrane because it contains several well characterized integral membrane proteins plus a peripheral cytoskeletal network. The major integral proteins are band 3 and several different types of glycophorin. The major cytoskeletal …

Hemagglutination by the hog cholera virus
… of hog cholera in the laboratory has been hampered by the fact that small laboratory animals cannot be used satisfactorily. In this work an attempt has been made to determine whether the hog cholera virus would agglutinate red blood cells and to determine optimal conditions for the reaction. …

Comparative effect of haemodynamic variables and rheological properties of the blood on the margination and adhesion of leukocytes and platelets
… and aggregation and deformability of red cells, we obtained evidence that leukocyte adhesion was dictated by the number of free-flowing cells 'marginated' near the vessel wall and the force experienced by their initial adhesive bonds. Platelet adhesion was dependent on the velocity of …

Glycerol permeability in two species of Peromyscus
… However, this same substance penetrated rat cells much more slowly.</p><p>Small but recognizable permeability differences were soo demonstrated among a number of species within a single genus. Levine (1943) investigated species differences in rates of osmotic hemolysis within the genus …

Nuclear and Plasma Membrane Properties of Macrophage Heterokaryons and Hybrids
… were fused with a strain of mouse melanoma cells which proliferates rapidly in vitro. The plasma membrane of the macrophage has specific receptors which enable the cell to ingest antibody-coated sheep red cells and is also rich in a divalent cation dependent adenosine triphosphatase (ATPase) …

Blood Reservoir Function of the Fetal Guinea Pig Liver
… liver functions as a blood reservoir, we measured liver blood volume under normal conditions and after hemorrhage and volume loading. Nineteen pregnant guinea pig sows and 54 near-term fetuses were injected intravenously with <sup>51</sup>Cr-labeled red cells while the fetuses remained in …

Design of a numerical model for simulation of blood microcirculation and study of sickle cell disease
… of painful medical conditions. In particular, unpredictable crises due to blood vessel occlusion remain one of the least understood stages of the disease, which focuses the attention of medical research. A novel methodology has been developed to address sickle cell disease, based on highly …

Characterizing Erythrocyte Motions in Flowing Blood
<p>Characterizing the probabilistic motions of cells is a prerequisite for the development of a general model of transport and surface deposition of white cells and platelets (WBC/P). These phenomena differ greatly when red blood cells (RBC) are present at normal levels, but follow convective …
