The Mechanism of Enzyme Decline in the Red Blood Cell During the “In Vivo” Aging Processremoval from the circulation remains largely unknown. A better understanding of the process of RBC senescence can be obtained by the study of cohorts of cells of progressively increasing age. Our laboratory has utilized for this purpose separation of RBC into groups of progressively increasing speci

The Relationship Between the Blood Oxygen Transport and the Human Red Cell Aging Processthe tissues. This study included several approaches. First, we observed that the affinity for O.in young RBCs was lower than in old RBCs (p<0.0005) due to different intracellular concentration of 2,3-diphosphoglycerate, main effector of hemoglobin. Second, we explored whether there are some subgroup

Hypotheses on the Physiological Role of Enzymatic Protein Methyl Esterification Using Human Erythroc by proposing that errors in protein biosynthesis might accumulate with age and reach a catastrophic level at which several vital components of an organism could no longer function to sustain life. Despite the overwhelming evidence against this theory, an important prediction of Orgel’s hypothesis w

Heterogeneity of Guanine Nucleotide Binding Proteins in Human Red Blood Cell Membranesassociation, multiple guanine nucleotide binding proteins have been identified both by SDS-PAGE analysis of native and of variously ADP-ribosylated membrane preparations and by FPLC chromatography of solubilised erythrocyte membranes preliminarily incubated with [α-.P] GTP in the presence of 5 mM Mg

In fact, nowadays, it is possible to follow individual cells all along their life span in circulation, it is possibl
