Hemoglobin Crete, 1 29 (H7) ala -k pro, is #{149} new mutant hemoglobin (Hb) with high oxygen affinity that was discovered in a Greek family in various combinations with #{176}and #{244} ’-thaIassemia. The propositus. who presented an unusual clinical picture of an “overcompenseted” hemolytic state. with erythrocytosis. splenomegaly. abnormal red cell morphology, and marked erythroid hyperplasi...

Hemoglobin A1c (HbA1c) is used routinely to monitor long-term glycemic control in people with diabetes mellitus, as HbA1c is related directly to risks for diabetic complications. The accuracy of HbA1c methods can be affected adversely by the presence of hemoglobin (Hb) variants or elevated levels of fetal hemoglobin (HbF). The effect of each variant or elevated HbF must be examined with each sp...

Thalassemia is a common public health problem among Malays. Hemoglobin C (Hb C) is a hemoglobin beta variant resulting from a single base mutation at the 6th position of the beta-globin gene leading to the substitution of glycine for glutamic acid. Hb C is commonly detected in West Africans and in African American but has not been reported in Malaysia. It can be falsely diagnosed as HbE trait i...

The human leukemia K562 cell line can be induced by 20 micro M hemin to reversibly accumulate embryonic and fetal hemoglobins without any change in the rate of cell division. When we reduced the rate of cell division by glutamine starvation or addition of hydroxyurea, the cells increased by tenfold the basal hemoglobin level of 0.3-0.5 pg Hb/cell. The combined effects of hemin and inhibitors of...

background: high maternal hemoglobin (hb) concentration was considered a risk factor for the developing of pregnancy hypertension. the purpose of this study was to determine whether high maternal hb concentration in first trimesters associated with pregnancy induced hypertension in iranian nulliparous women. methods: this study was carried out in teaching hospital in sari, iran. samples were ob...

The convenience of dried blood filter paper specimens for genetic screening programs has prompted us to test the stability of these specimens for hemoglobin identification by cation exchange high performance liquid chromatography. This report shows that identification of Hb AA, Hb AF, Hb AS, Hb FAS, Hb AJ, Hb FJ, Hb EF, and Hb SS can be achieved by high performance liquid chromatography even af...

Background: High maternal hemoglobin concentration has been increasingly linked to poor pregnancy outcomes in recent years. This study was aimed to determine whether high maternal hemoglobin (Hb) in first trimester is associated with preeclampsia. Materials and Methods: In 2009 a retrospective study was conducted and demographic and obstetric records of 1513 low risk pregnant mother registered ...

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 ...

hemoglobinopathies are the most common single gene disorders worldwide with a considerable frequency in certain area particularly mediterranean and middle eastern countries. hemoglobinopathies include structural variants of hemoglobin (hb s, hb c, hbe,…) and thalassaemias which are inherited defects in the globin chains synthesis. the present study was conducted to determine the prevalence of h...
