deleanu, frei, and hilton have developed the notion of generalized adams completion in a categorical context. in this paper, we have obtained the postnikov-like approximation of a module, with the help of a suitable set of morphisms.

OBJECTIVE To investigate blood oxidative status of patients with chronic renal failure (CRF) and possible effects of hemodialysis on the development of oxidative stress in blood. MATERIALS AND METHODS The levels of malondialdehyde (MDA) and oxidation resistance (OR) values were measured in blood plasma, erythrocyte hemolysate and erythrocyte membrane fractions of 33 patients with CRF and of 1...

We investigated the vascular responses and the blood pressure reducing effects of different fractions obtained from the methanol extract of Loranthus ferrugineus Roxb. (F. Loranthaceae). By means of solvent-solvent extraction, L. ferrugineus methanol extract (LFME) was successively fractionated with chloroform, ethyl acetate and n-butanol. The ability of these LFME fractions to relax vascular s...

The contractile activity of various fresh, or incubated blood fractions was studied in vitro using the isolated canine basilar artery. Significantly greater contraction was induced by fresh platelet rich plasma (PRP) and serum compared to red blood cells (RBC). Following incubation, the contractile activity of RBC increased, reaching a plateau at day-3 and it was maintained for at least 14 days...

Continuous-flow paper electrophoresis has been used to separate human blood serum and extracts of the formed elements of blood into several frac tions exhibiting lactic dehydrogenase (LDH) activity (1, 2, 4). Fractionation patterns obtained by this procedure have been shown to differ from normal in certain diseases. The pattern differences were not attributable to the appearance of new fraction...

objective: homalium letestui pellegr (flacourtiaceae) is used in traditional medicine in parts of nigeria for the treatment of malaria, ulcer, and inflammatory diseases and as an aphrodisiac. this investigation was aimed to evaluate the cytotoxic, immunomodulatory, and antileishmanial properties of stem extract and fractions of homalium letestui (h. letestui). materials and methods: cytotoxic a...

Studies of the hemoglobin pattern in Brazilian reptiles are important for determining ecological and phylogenetic relationships, but they are scarce. Peripheral blood samples were obtained from 7 males and 18 females of Rhinoclemmys punctularia. The hematological profile was based on the total hemoglobin and hematocrit values. The hemoglobin profile was obtained using electrophoretic procedures...

The objective of this study was to compare the electrophoretic pattern serum proteins in newborn calves, lambs, goat kids and piglets precolostral blood samples. Blood samples were collected within 30 min birth, prior ingestion first colostrum, concentrations total protein fractions analyzed using electrophoresis on agarose gel. size shape electrophoretograms differed among investigated animal ...

As part of the AACR Annual Meeting Methods Workshop "Sample Collection, Processing, and Storage for Large-Scale Studies: Biorepositories to Support Cancer Research," blood specimen collection, processing, storage, and dissemination issues were discussed. Whole blood and blood fractions comprise a major portion of biospecimen collections for population-based studies. Although procedures for coll...
