BACKGROUND Cadmium (Cd), lead (Pb), and mercury (Hg) cause toxicological renal effects, but the clinical relevance at low-level exposures in general populations is unclear. The objective of this study is to assess the risk of developing end-stage renal disease in relation to Cd, Pb, and Hg exposure. METHODS A total of 118 cases who later in life developed end-stage renal disease, and 378 matc...

BACKGROUND Some preliminary observations suggest that predisposition to a particular type of glomerulonephritis (GN) may be connected with the genetically determined charge of the glomerular capillary wall. A correlation between erythrocyte surface and the glomerular capillary wall charges has also been observed. The purpose of this study was to verify and extend previous investigations. Theref...

Pathological erythrocyte aggregation reduces capillary perfusion and oxygen transfer to tissue, which is determined by the negative surface charge on membrane (intrinsic aggregability) fibrinogen–erythrocyte interaction (extrinsic factor). Exercise-induced oxidative stress important for rheological adaptation training but may also cause senescence. This study clarifies effects of hypoxic exerci...

Infection of erythrocytes with the human malaria parasite, Plasmodium falciparum, results in dramatic changes to the host cell structure and morphology. The predicted functional localization of the STEVOR proteins at the erythrocyte surface suggests that they may be involved in parasite-induced modifications of the erythrocyte membrane during parasite development. To address the biologic functi...

Erythrocyte is human blood main bactericidal cell. During movement in blood stream erythrocytes are triboelectrically charged by rubbing to each other and vessel walls and this charge automatically attracts and keeps bacteria on erythrocyte surface. Bacteria fixation on erythrocyte membrane activates the receptors of the membrane and stimulates trans membrane releasing of oxygen from oxyhemoglo...

BACKGROUND Reduced erythrocyte survival and deformability may contribute to the so-called anemia of inflammation observed in septic patients. Erythrocyte structure and function are affected by both the membrane lipid composition and the organization. We therefore aimed to determine whether these parameters are affected during systemic inflammation. METHODS A sensitive matrix-assisted laser de...

Intracellular polymerization and sickling depend markedly on the cellular concentration of sickle hemoglobin (Hb S). A possible therapeutic strategy for sickle cell disease is based on reducing the cellular concentration of Hb S through prevention of erythrocyte dehydration. The K-Cl cotransporter is a major determinant of sickle cell dehydration and is inhibited by increasing erythrocyte Mg co...

OBJECTIVE O-linked N-acetylglucosamine (O-GlcNAc) is upregulated in diabetic tissues and plays a role in insulin resistance and glucose toxicity. Here, we investigated the extent of GlcNAcylation on human erythrocyte proteins and compared site-specific GlcNAcylation on erythrocyte proteins from diabetic and normal individuals. RESEARCH DESIGN AND METHODS GlcNAcylated erythrocyte proteins or G...

The phospholipid and cholesterol derivatives N-(7-nitro-2,1,3-benzoxadiazol-4-yl)phosphatidylethanolamine (NBD-PE) and N1-cholesterylcarbamoyl-N8-(7-nitro-2,1,3-benzoxadiazol-4-yl )-3,6-dioxaoctane-1 , 8-diamine (NBD-Chol), respectively, were incorporated into egg phosphatidylcholine/cholesterol multilamellar liposomes, human erythrocyte ghost membranes, and multilamellar liposomes derived from...

Objective– O-linked N-acetylglucosamine (O-GlcNAc) is up-regulated in diabetic tissues, and plays a role in insulin resistance and glucose toxicity. Here, we investigated the extent of GlcNAcylation on human erythrocyte proteins and compared site-specific GlcNAcylation on erythrocyte proteins from diabetic and normal individuals. Research Design and Methods– GlcNAcylated erythrocyte proteins or...
