background: various studies have come to contradictory results regarding the relationship between maternal hemoglobin (hb) level and adverse pregnancy outcomes. the present study aimed to investigate the birth outcomes among pregnant women who had normal hemoglobin levels in the first trimester of their pregnancy. patients and methods: in this prospective study, 108 healthy pregnant women with ...

background: blood hemoglobin can be damaged by toxins such as lead. thus, this study was carried out to assess its blood hemoglobin concentration in the staff of kermanshah oil refinery that had been exposed to lead components. methods: in this study, 150 workers at kermanshah oil refinery were selected as the case group and 70 workers of textile industry factory were chosen as the control grou...

conclusions the levels of hemoglobin can be used to predict preeclampsia and monitoring the pregnant women and its regular measure in 3 trimesters help us to identify women at risk for preeclampsia. background preeclampsia is one of the most serious complications during pregnancy with important effects on health of mother and fetus that causes maternal and fetal morbidity and mortality. this st...

The in uitm biosynthesis of acetylated human fetal hemoglobin (Hb FI) was investigated in umbilical cord blood from two normal newborns and in peripheral blood from five adults with different hematologic disorders accompanied by elevated levels of fetal hemoglobin. Hemoglobin biosynthesis was measured by [8HJleucine incorporation into hemoglobin components which were separated by chromatograph...

Introduction The continuous and rapid growth of telecommunication industries, along with the common application of cell phones, hasraised debates on the associated risks for humanhealth due to exposure to radiofrequency fields, caused bycell phonesorother sources, and industrial and medical applications. Accordingly, in this study, we aimed to investigate the effects of cell phone radiation on ...

Hydrogen peroxide (H(2)O(2)) triggers a redox cycle between ferric and ferryl hemoglobin (Hb) leading to the formation of a transient protein radical and a covalent hemeprotein cross-link. Addition of H(2)O(2) to highly purified human hemoglobin (HbA(0)) induced structural changes that primarily resided within beta subunits followed by the internalization of the heme moiety within alpha subunit...

It has previously been shown that addition of catecholamines to a suspension of trout erythrocytes induces an enlargement of the cells owing to an uptake of NaCl mediated by a cAMP-dependent, amiloride-sensitive Na+/H+ exchange. In this article, we show that the change in cell volume induced by catecholamines is much greater when the erythrocytes are incubated in N2 than when they are in O2. Th...

a simple, rapid new technique is described for the electrophoresis of hemo­globin when screening large human populations. the method uses a drop of finger tip's blood dried on a thick filter paper as the specimen. the simplicity of the sampling, tagging, transportation and electrophoresis, provides a reliable procedure for surveys of large population. in our hand 200 specimens were screened dur...
