BACKGROUND Persistent mixed chimerism represents a state in which recipient and donor cells stably co-exist after hematopoietic stem cell transplantation. However, since in most of the studies reported in literature the engraftment state was observed in the nucleated cells, in this study we determined the donor origin of the mature erythrocytes of patients with persistent mixed chimerism after ...
Single amino acid substitutions in the globin chain are the most common forms of genetic variations that produce hemoglobinopathies--the most widespread inherited disorders worldwide. Several hemoglobinopathies result from homozygosity or compound heterozygosity to beta-globin (HBB) gene mutations, such as that producing sickle cell hemoglobin (HbS), HbC, HbD and HbE. Several of these mutations...
The structural and functional conservation of hemoglobin throughout mammals has made the laboratory mouse an exceptionally useful organism in which to study both the protein and the individual globin genes. Early researchers looked to the globin genes as an excellent model in which to examine gene regulation - bountifully expressed and displaying a remarkably consistent pattern of developmental...
abstract background and objective: normal hemoglobin (hb) is formed of a heme group and a protein group known as globin. globin is made of four polypeptide chains and in hemoglobinopathies, the structure of one of these four polypeptide chain becomes abnormal. cellulose acetate method is a common way to differentiate haemoglobinopathies. inability to identify the components of hb low co...
T HE MODERN ERA ofprenatal testing for hematologic diseases began in 1974. Prior to that time, the only test available consisted of determination of fetal sex following amniocentesis in cases at risk for sex-linked disorders, such as the hemophilias. Methods for obtaining fetal blood in utero in ongoing pregnancies were initiated in 1974, and these developments led to the possibility of prenata...
INTRODUCTION β-Thalassemia and hemoglobinopathies are common genetic disorders in Turkey and in this retrospective study our aim was to determine the frequency of β-thalassemia and hemoglobinopathies in Adana, which is one of the biggest cities located in the southern part of Turkey. MATERIAL AND METHODS Data from 3000 individuals admitted to Seyhan Hereditary Blood Disorders Center in Adana ...
