Assessment of blood ABO group Participants were asked to report their blood ABO group in the first questionnaire as O, A, B, or AB, as well as their Rhesus group as positive or negative. Assessment of smoking status Smoking status was considered at every questionnaire, and was based on self...
Blood group antigens are immunogenic polymorphic molecules presented on the surface of RBCs. This study aimed to determine extended blood group profiles (ABO, Rhesus, Kell, Kidd, Duffy, MNS, Cartwright, Dombrock, Colton, Lutheran, and Vel) in Malays, Chinese, and Indians in Peninsular Malaysia...
Because most Blood test reference ranges (often referred to as 'normal' ranges of Blood test results) are typically defined as the range of values of the median 95% of the healthy population, it is unlikely that a given Blood sample, even from a healthy patient, will show "normal" values...
Blood group A was consistently associated with increased gastric cancer risk in different subgroups stratified by ethnicity, publication year, study sample size, source of control population, study quality score and prevalence of Helicobacter pylori infection. Group AB was associated with gastric cancer ...
Human histo-blood group A transferase (AT) catalyzes the biosynthesis of oligosaccharide A antigen important in blood transfusion and cell/tissue/organ transplantation. This enzyme may synthesize Forssman antigen (FORS1) of the FORS blood group system when exon 3 or 4 of the AT mRNA is deleted...
In this group of patients, age of pRBC may be of importance, whereby severely ill ICU patients with poor MCF may profit from shorter stored blood. Similarly, calculations for PVD showed these results in the regression model. Two possible explanations could be (1) the pre-existing impairment ...
In an interesting study from the same group,16 the UAC/BAC ratio was determined after volunteer subjects drank a standard dose of ethanol (0.85 g/kg body weight) in the form of neat whiskey over 25 min on an empty stomach. The subjects emptied their bladders of any residual urine before...
Although the action of Epo on erythropoiesis is rapid, evidence of a regenerative response is not immediately apparent in a blood sample. One of the main effects of Epo is to expand the pool of early-stage erythroid precursors, and it takes time for these cells to differentiate to the point...
(Table1and Supplementary Fig.1). We performed chi-squared tests of independence and found insufficient evidence to conclude that the blood-group frequencies differ between SARS-CoV-2-tested and non-tested groups (Supplementary Table1). Individuals were considered initially SARS-CoV-2-positive (COV+...
Human Blood Group A Glycosyltransferases: Hisao TAKIZAWA (Natl. Res. Inst., Police Sci., Tokyo; Present address: DepL Legal Med., Fac. Med., Toyama Med. Pharm. Univ., Toyama) The purpose of this study is to examine the immunochemical properties of human blood group A glycosyltransferases....
