AND MORTIMER GARRISON, JR. T HERE IS considerable interest currently with respect to the acid elution metho)d of Kleihauer, Braun and Betke1 for detecting cytologically those circulating erythrocytes which have an appreciable content of fetal hemoglobin (“F-containing cells” ) . The method is based on the lower solubility of alkaliresistant or fetal hemoglobin in an acid environment as compared...

The X-ray structure of a dimeric, cyanomet-liganded hemoglobin D-chain (Hb-D) from Caudina arenicola has been determined by the molecular-replacement method. The search model was a concatenated model of three hemoglobin structures superimposed on the backbone of monomeric, hemichrome hemoglobin C-chain (Hb-C) from the same organism. Hb-D crystallizes in space group P4(1)2(1)2 with cell constant...

the ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. in the present work, aggregation of the purified hemoglobinin adult (hba) and in fetus or newborn (hbf) in the presence of nitrite ions were studied.hemoglobin aggregation was perform...

In type 2 diabetic patients, the relationships between 25-hydroxyvitamin D and parathyroid hormone levels, and glycemic control, remain unclear. We evaluated associations between 25-hydroxyvitamin D, parathyroid hormone, and hemoglobin A1c levels after adjusting for other covariates, including log transformed 25-hydroxyvitamin D levels and log transformed parathyroid hormone levels, in Korean p...

Proposition O was created to help the City of Los Angeles comply with the Total Maximum Daily Load (TMDL) requirements under the Clean Water Act. In this study, the effectiveness of the Proposition O projects in Los Angeles River watershed was examined to show whether it achieves the goal of meeting water quality standards. Our analysis shows the most effective single project will remove at mos...

BACKGROUND AND AIMS Despite growing interest in the protective role that vitamin D may have in health outcomes, little research has examined the mechanisms underlying this role. This study aimed to test two hypotheses: (1) serum 25-hydroxyvitamin D [25(OH)D] is inversely associated with type 2 diabetes mellitus (T2DM) and elevated hemoglobin A1c; (2) these associations are mediated by serum C-r...

data on 300 kermani sheep from kermani breeding center of shahrbabak were utilized in the present research. horizontal polyacryle amide electrophoresis was employed to detect polymorphism of transferrin and albumin, while acetate cellulose being utilized for hemoglobin. three genotypes of hemoglobin were observed(aa, ab and bb with respective frequencies of 4.6, 43.8 and 51.6). frequency of a a...
