Background & Aims of the Study: Gasoil is one of most-used oil products applied as diesel fuel, for instance, which, since it consists of aromatic compounds, is among the most important environmental pollutants. Considering its harmful effects on living organisms and human beings, the purpose of the present study was to investigate the effects of gasoil ingestion on blood factors of white ...
The switch from fetal to adult hemoglobin is incomplete; the residual fetal hemoglobin in adults is restricted to a subset of erythrocytes called F cells. F-cell levels are influenced by a sequence variant (C-->T) at position -158 upstream of the gamma-globin gene, termed the XmnI-Ggamma polymorphism. How the Ggamma-158 C-->T variant influences the expression of the Ggamma-globin gene is unknow...
The human globin genes are among the most extensively characterized in the human genome, yet the details of the molecular events regulating normal human hemoglobin switching and the potential reactivation of fetal hemoglobin in adult hematopoietic cells remain elusive. Recent discoveries demonstrate physical interactions between the beta locus control region and the downstream structural gamma-...
We describe an HPLC-based method for the detection and quantification of fetal hemoglobin in stools of newborns. The new procedure is an alternative to the classic qualitative test for adult hemoglobin in meconium based on the differential stability of hemoglobin species in dilute base (Apt test). The HPLC method, based on a commercial device for hemoglobin characterization (Bio-Rad Variant), r...
We determined the millimolar absorptivities of the four clinically relevant derivatives of fetal and adult human hemoglobin in the visible and near-infrared spectral range (450-1000 nm). As expected, spectral absorption curves of similar shape were found, but the small differences between fetal and adult hemoglobin absorptivity were important enough that they should be taken into account in mul...
