hemoglobin AS

06/01/2012 - "Haemoglobin AS, CC, and AC genotypes and homozygous and heterozygous α-thalassaemia provide significant protection from severe malaria syndromes, but these haemoglobinopathies differ substantially in the degree of protection provided and confer mild or no protection against uncomplicated malaria and asymptomatic parasitaemia. "
01/01/2015 - "We then identified exposure-matched controls with "average numbers of malaria" episodes, and found that the EM group had higher parasite densities when asymptomatically infected or during clinical malaria, and were less likely to be of haemoglobin AS genotype. "
10/01/2011 - "Hb levels were significantly decreased in all the malaria patients which indicates that malaria parasite uses host erythrocyte Hb as a major nutrient source. "
05/09/2008 - "Intraerythrocytic malaria parasites use host hemoglobin as a major nutrient source. "
01/01/1992 - "In both regions, prevalence of malaria was not significantly different between Hb AA people and Hb AS people. "

01/01/2009 - "Future studies should explore whether these risk factors might include haemoglobin AS sickle cell disease, a common trait in the West African general population."
07/01/1991 - "To study the potential of multivariate classification methods in order to obtain more insight into abnormal laboratory data from patients with sickle cell disease, we investigated standard haematological and clinical chemical variables of 18 controls and 37 apparently healthy persons with heterozygous sickle cell disease (Hb AS), all women, using both univariate and multivariate classification methods. "
01/01/2011 - "Blood samples were collected from 211 Hb AS blood donors, 119 Hb AA blood donors as a control group, and 28 sickle cell disease patients (Hb SS). "
03/01/2009 - "Of these, 22 (5.97%) showed heterozygous sickle cell gene(Hb-AS or trait) and one (0.27%) homozygous form (Hb-SS or sickle cell disease). "
03/01/2009 - "Prevalence of sickle cell anemia was found to be 9.2% (155/1676) of which 0.8% (14/1676) were homozygous (disease, Hb SS) whereas 8.4% were heterozygous (carrier, Hb AS). "

12/01/2011 - "No deaths from the condition have been reported previously, whereas death after vigorous physical activity in individuals with sickle cell trait (hemoglobin AS) has been described in a few case reports. "
02/01/2008 - "We conclude that the H/H131 genotype and H131 allele rather than Hb AS genotype (sickle cell trait patients) appear to associate with the Fulani ethnic group."
11/01/2007 - "Sickle cell trait (hemoglobin AS) is the most common genotype and has traditionally been considered a benign condition. "
09/01/2004 - "BACKGROUND Red blood cell (RBC) components from donors with sickle cell trait (Hb AS) often occlude white blood cell (WBC) reduction filters. "
07/01/2003 - "To determine whether sickle cell trait (hemoglobin AS) is associated with abnormalities in the brain of asymptomatic children. "

11/01/2006 - "The aim of this study was to investigate the role of anemia at presentation (basal HB) and during treatment (nadir HB) as predictor of pathological response, as well as disease-free (DFS) and overall survival (OS) in LACC patients undergoing chemoradiation followed by radical surgery. "
10/18/2012 - "At 6 month follow-up, change in hemoglobin as well as new-onset anemia was studied as a function of RDW at discharge. "
05/01/2004 - "Hematological profiling in both strains is consistent with the presence of anemia as evidenced by low total erythrocyte counts, decreased hemoglobin, as well as abnormally high numbers of circulating reticulocytes (15-20%). "
12/01/2000 - "Anemia was found in 18.7% of female overweight and obese subjects, using hemoglobin as an indicator. "
04/01/1979 - "Observations on the rate and mechanism of hemolysis in individuals with Hb Zürich [His E7(63)beta leads to Arg]: II. Thermal denaturation of hemoglobin as a cause of anemia during fever."

09/01/2003 - "The presence of hemoglobinopathy (Hb AS) is also a mark of its originality."
01/01/1997 - "The patient had a second apparently fortuitous hereditary affection: hemoglobinopathy (Hb AS). "
01/01/1990 - "These studies have left unanswered some questions, however, such as whether antifibrinolytics are as effective in children as adults, in white patients as black, and in patients with normal hemoglobin as well as those with sickle cell hemoglobinopathies. "
10/01/2014 - "The aim of the study is to examine the relationship between sickle cell trait (Hb AS) and other sickle hemoglobinopathies and the risk of thromboembolism during pregnancy or the puerperium. "
08/01/2001 - "A study of reproductive outcome in Mobile, AL was conducted among a large maternal cohort with sickle-cell disease (Hb SS), sickle-cell trait (Hb AS), and no hemoglobinopathies (Hb AA). "
