92.6 (19). Sialic acids have been found on the eryth rocyte membranes of a number of vertebrate species (5, 7, 192). Viral or bacterial neuramini dases, enzymes which cleave the a-ketosidic link age between a terminal sialic acid group and a sugar or sugar derivative (9), can liberate free sialic acid from such red cell membranes (5, 7). The surface of the mammalian erythrocyte is neg atively c...

Anthracyclines, a class of antitumor drugs widely used for the treatment of solid and hematological malignancies, cause a cumulative dose-dependent cardiac toxicity whose biochemical basis is unclear. Recent studies of the role of the metabolites of anthracyclines, i.e., the alcohol metabolite doxorubicinol and aglycone metabolites, have suggested new hypotheses about the mechanisms of anthracy...

background: arsenic is one of the most toxic metalloids. anemia and leukopenia are common results of poisoning with arsenic, which may happen due to a direct hemolytic or cytotoxic effect on blood cells. the aim of this study was to examine the effects of hydroalcoholic extract of nasturtium officinale on blood cells and antioxidant enzymes in rats exposed to sodium (meta)arsenite. methods: 32 ...

Human erythrocyte lysate proteins were resolved into over 250 discrete spots by two-dimensional electrophoresis using isoelectric focusing in the first dimension and electrophoresis in the presence of sodium dodecyl sulfate, (SDS) in the second. The overwhelming excess of hemoglobin has made such analyses difficult in the past. However, with the ISO-DALT two-dimensional electrophoresis system, ...

Background: The development of anti-red blood cell alloantibodies remains a major problem in transfusion of blood in thalassemia major patients. Also, Autoantibodies can result in clinical hemolysis and difficulty in cross-matching blood. We studied the frequency of red blood cell alloimmunization and autoimmunization among thalassemia patients who received regular transfusions in Ilam province...

Cell wall isolation procedures were evaluated to determine their effect on the total pectin content and the degree of methylesterification of tomato (Lycopersicon esculentum L.) fruit cell walls. Water homogenates liberate substantial amounts of buffer soluble uronic acid, 5.2 milligrams uronic acid/100 milligrams wall. Solubilization appears to be a consequence of autohydrolysis mediated by po...

This study investigated the effects of different protein sources and butyric acid contents in aquafeed on growth, survival rate, lipid peroxidation enzymes, intestinal villi 7.3 g jade perch, Scortum barcoo. The experimental treatment groups were whole fish meal (FM) group, FM + (FMB) 50% black soldier fly (FBM) FBM (FBMB) (BM) BM (BMB) group. results showed that perch fed with FMB feed had a s...
