Hypoxanthine Transport in Human Erythrocytes
1980De novo synthesis of purines does not appear to take place in mature human erythrocytes because the enzymes for the pathway are absent1. Therefore purine bases should be normally have to be supplied exogenously to erythrocytes.

Shear fragility of human erythrocytes
Biorheology, 1971Shear breakage of human blood cells in saline solution has been studied under conditions of uniform shear, non-penetrating thickeners having been added merely to facilitate application of a sufficiently high stress using a conventional cone and plate apparatus. Cells in isotonic saline fragment and many micro spheres are formed.

Human erythrocytes’ perplexing behaviour: erythrocytic microRNAs
Molecular and Cellular BiochemistryErythrocytes have the potential role in erythropoiesis and disease diagnosis. Thought to have lacked nucleic acid content, mammalian erythrocytes are nevertheless able to function for 120-140 days, metabolize heme, maintain oxidative stress, and so on.

The utilization of formate by human erythrocytes
Biochimica et Biophysica Acta (BBA) - General Subjects, 1973Abstract The incorporation of radioactive formate into an acid-stable non-volatile form by human erythrocytes is dependent upon the addition of 5-amino-4-imidazolecarboxamide riboside. The formate-incorporating activity of human erythrocytes varies widely among normal individuals and the values obtained are characteristic of the erythrocytes obtained

Guanine Uptake by Human Erythrocytes
1991It has been clearly established that mature human erythrocytes cannot synthesize de novo purines (1); consequently the turnover of purine nucleotides in red cells must result from the continual entry and release of purines. Hypoxanthine and adenine uptake by human erythrocytes has been studied in our laboratories (2–4).

Uptake of Adenosine in Human Erythrocytes
1980The transport of nucleosides across mammalian cell membranes is performed by a transport system with broad specificity for purine and pyrimidine nucleosides, For this uptake process a two comnonent system is discussed; one for low physiological and another for high concentrations of nucleosides (1, 2, 3). In human blood platelets a close association of

The osmometric behavior of human erythrocytes
Cryobiology, 1979Abstract A reexamination of the data of Farrant and Woolgar ( Cryobiology , 9 , 9–15 (1972)) demonstrates that human erythrocytes exhibit osmometric behavior as predicted from the Boyle-Van't Hoff law when suspended in sodium chloride solutions as high as 3.5 osmolal. A Boyle-Van't Hoff plot is linear with r = 0.998.

Substructure of human erythrocyte spectrin
Journal of Supramolecular Structure, 1979AbstractThe human erythrocyte structural protein spectrin and its subunits I, II were isolated in the presence of Na‐dodecyl‐sulfate by gel filtration and preparative gel electrophoresis. After removal of the detergent, spectrin alpha‐helical content is comparable to spectrin isolated without detergent.

Allopurinol transport in human erythrocytes
Biochemical Pharmacology, 1993The mechanism of allopurinol [4-hydroxypyrazolo(3,4-d)pyrimidine] transport into human erythrocytes was investigated with an inhibitor stop assay. Allopurinol transport could be resolved into two components: (1) a saturable system and (2) a non-saturable process, which most likely represents non-facilitated diffusion.
