This study examined the association between hemoglobin (Hb) concentrations in sows and number of stillborn pigs. Based on late gestation Hb concentrations, prepartum intrapartum pigs was greater (P < .001) anemic than nonanemic sows.
the purification of biomolecules is a necessary step in many biochemical researches. in this regard, developments of convenient, specific and low cost methods of purification are of particular interest. given the human hemoglobin (hb) affinity toward some charged carbohydrates, interaction of this molecule with human chorionic gonadotropin (hcg) which is a glycoprotein hormone containing sialic...
Serial blood draws for the assessment of trauma patients' hemoglobin (sHgb) and hematocrit (sHct) is standard practice. A device that would allow for continuous real-time, non-invasive monitoring of hemoglobin and tissue perfusion would potentially improve recognition, monitoring and resuscitation of blood loss. We developed a device utilizing diffuse optical spectroscopy (DOS) technology that ...
Studies were carried out during the 1st yr of life in normal infants born at term to determine the proportions of fetal hemoglobin (Hb F) and adult hemoglobin (Hb A) being synthesized, in order to describe the complete switchover from Hb F to Hb A synthesis during postnatal life. 53 blood samples from 37 infants were incubated in an amino acid mixture containing [14C]leucine and chromatographed...
High performance liquid chromatography (HPLC) demonstrated advantages over conventional procedures employed in newborn and adult hemoglobinopathy screening programs for the identification of Hb variants has promoted the need to reassess our knowledge of hemoglobin reference ranges as it relates to HPLC quantitation. In this study, the HPLC hemoglobin reference ranges derived from 200 normal Afr...
Hemoglobin release test (HRT), which is established by our lab, is a new experiment to observe the re-released hemoglobin (Hb) from erythrocytes. In this study, onedimension HRT, double dimension HRT, and isotonic and hypotonic HRT were performed to observe the re-released Hb from the blood samples of normal adult, hereditary spherocytosis (HS), and α-thalassemia. The results showed that compar...
OBJECTIVE Alpha-thalassemia is frequently encountered in eastern Saudi Arabia. We wanted to find out laboratory based incidence and laboratory features of Hemoglobin H disease in the Dammam region. METHODS We retrospectively analyzed the results of Hemoglobin electrophoresis carried out during the last 5 years in our laboratory. Hemoglobin electrophoresis was performed on cellulose acetate, p...
A reference method that specifically measures hemoglobin (Hb) A1c is an essential part of the reference system for the international standardization of Hb A1c/glycohemoglobin. We have developed a new method for quantification, based on the specific N-terminal residue of the hemoglobin beta-chains. Enzymatic cleavage of the intact hemoglobin molecule with endoproteinase Glu-C has been optimized ...
A a Abstract. In this study we report the fortuitous description of hemoglobin (Hb) Hope in a Tunisian athlete. This Hb is one of hemoglobin variants that show a lower stability and oxygen affinity that is beneficial to tissue oxygen delivery. Hb Hope was isolated by automated high performance liquid chromatography and was unequivocally found to be Hb Hope using DNA-based methods: polymerase ch...
Accurate and precise hemoglobin separation and the quantitation of Hb A2 and Hb F are essential for the diagnosis of the thalassemias and hemoglobinopathies. Presented in this study is the validation of the the Hb A2 assay of the HbGold analyzer, a fully automated liquid chromatography system for hemoglobin separation and quantitation. Variability of Hb A2 quantitation was quite low; the CV's o...
