Assessment of exposure to airborne endotoxins has been studied for several years, especially in occupational environments, but a large number of procedures are used for sampling and analysis. This lack of standardization makes it very difficult to compare results and set internationally accepted threshold limit values (TLVs) or occupational exposure limits (OELs) for endotoxin exposure. This pa...

Cat hemoglobin has been found to exist in three forms which differ in the cooperativity of oxygen binding at low and high pH values. Type I cat hemoglobin has a high cooperativity (n = 2.7 to 3.1) at both high (pH = 7.8 to 9.0) and low (pH = 6.5 to 6.9) pH values. Type II hemoglobin exhibits low cooperativity (n = 1.8 to 2.3) in the low pH range but high cooperativity in the high pH range. Type...

The contribution of water to the quantitative determination of hemoglobin concentration and saturation by near-infrared spectroscopy in turbid media was investigated. The study consisted of in vitro measurements of an aqueous suspension containing Liposyn, bovine blood, and yeast buffered at pH 7.2. The optical coefficients of the medium (ma;0.03 to 0.08 cm −1, ms8 ; 6 cm −1 at wavelengths of 7...

background: sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. the purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. methods: a cross-sectional study was conducted among the sickle cell patients atten...

Infant iron status at birth is influenced by maternal iron status during pregnancy; however, there are limited data on the extent to which maternal iron status is associated with infant iron status during exclusive breastfeeding. We evaluated how maternal and infant hemoglobin and iron status [soluble transferrin receptors (TfR) and ferritin] were related during exclusive breastfeeding in HIV-i...

Alpha thalassemia (α-thal) is relatively common worldwide. Most carriers are defective in either one or two alpha globin genes out of four functional ones, with deletions being more common than point mutations. The hematologic features are very important for the selection of the appropriate molecular tests while determining the genotype. The aim of this study was to compare hematologic features...

Background. Maximal Aerobic Power is related to many quantities and qualities such as supplements. Objectives. The purpose of the present study was to describe the effect of short-term supplementation of glutamine and glucose on hemoglobin and maximum aerobic power in female athletes. Methods. In this quasi-experimental study, 40 female athletes (age 21.9±2.6 years, height 161.8&...

Near-infrared imaging was used to quantify typical values of hemoglobin concentration, oxygen saturation, water fraction, scattering power, and scattering amplitude within the breast tissue of volunteer subjects. A systematic study of the menstrual variations in these parameters was carried out by measuring a group of seven premenopausal normal women (aged 41 to 47 years) in the follicular (day...
