Facilitated diffusion in rabbit erythrocytes
… kinetic study of the permeability of rabbit erythrocytes has established that carrier systems are involved in the penetration of certain non-electrolytes. Saturation, competitive inhibition, and butanol inhibition kinetics were used to demonstrate the presence of carrier systems and the …

Possible carriers in mouse erythrocytes
Early qualitative erythrocyte permeability studies (Gryns, 1896; Hedin, 1897) revealed the wide range of non-electrolyte permeability rates across a cell membrane composed of lipid molecules. Theoretically, water-soluble non-electrolytes such as glycerol, ethylene glycol and erythritol would …

The thiourea carrier in human erythrocytes
… characteristics of the thiourea carrier in human erythrocytes taking into consideration the two parameters of transfer (half-saturation constant and maximum transport rate) and the energy of dissociation of the carrier complex. In the president experiment, the problem has been approached by …

Simple and facilitated diffusion in rat erythrocytes
… late nineteenth century, workers chose to use erythrocytes due to their advantages over using a variety of cell types. With erythrocytes a comparison could be developed between strictly homologous cells of many different species. Erythrocytes are easily obtainable and mature cells are separate …

Deoxyribophosphoaldolase of human erythrocytes: identification, purification and characterization
… exposition, it was not known to exist in human erythrocytes. However, the enzyme was postulated to occur in erythrocytes in order to account for the synthesis of glyceraldehyde-3-P observed in ghosts when deoxynucleosides were metabolized. Therefore, initial experiments were designed to detect …

Cytoplasmic RNA-dependent RNA-synthesis in maturing chicken erythrocytes.
… polymerase from ribosomes of maturing chicken erythrocytes was investigated. Concurrent with an increase in globin and RNA synthesis during phenylhydrazine induced anaemia, the total and specific activities of ribosome bound RNA-dependent RNA polymerase increased 40 and 9.4 times respectively, …

The Role of Adenosine Signaling In Mature Erythrocytes and Erythroid Progenitors
<p>Adenosine is a ubiquitous nucleoside in almost all the cells throughout our bodies. It is highly induced particularly under hypoxia or energy depletion conditions. Adenosine functions as a critical ligand, after binding to membrane-associated adenosine receptors, adenosine initiates a downstream …

Glycerol permeability in erythrocytes of Peromyscus californicus : the effect of temperature
The present work was done to determine the effect of temperature of the half-saturation constant (ø) and the maximum transport rate (K) of the facilitated diffusion of glycerol across the erythrocyte membrane of Peromyscus californicus.

Host cell-pathogen interactions between erythrocytes and P. falciparum: apoptotic mimicry?
… the phagocytic process of malaria-infected erythrocytes and the subsequent cascade of host response are important in developing new strategies for treating malaria. In this study, we focused on phosphatidylserine (PS) and its possible role in malaria pathogenesis through phagocytosis. …

Liposomal delivery of PDE5 inhibitors and UT-15C to human erythrocytes
… of adenosine triphosphate (ATP) from human erythrocytes is an important mechanism for the regulation of vascular caliber. However, erythrocytes from patients with pulmonary arterial hypertension (PAH) fail to release ATP in response to the physiological stimuli of exposure to low oxygen …

Biochemical and Molecular Assessment of Toxicity of Primaquine Metabolites on Erythrocytes
… for toxicity of PQ, normal and G6PDd human erythrocytes were treated with the potential hemotoxic metabolites of PQ namely, 5-hydroxy-primaquine (5-HPQ), 5,6-orthoquinone primaquine (5,6-OQPQ) and 6-methoxy-8-hydroxylaminoquinoline (MHQ). The early and late biomarkers of hemotoxicity were …

Erythrocytes derived microvesicles : their characterisation and potential role as delivery vectors
Extracellular vesicles (EV) are heterogeneous populations of small vesicles released by virtually all cells and are classified depending on their biogenesis and size. Microvesicles (MV) are a subtype of EV and are released under optimal cell conditions and/or upon stimuli. In this study, the …
