There are three common alleles (A, B, and O) at the human ABO blood group locus. We compared nucleotide sequences of these alleles, and relatively large numbers of nucleotide differences were found among them. These differences correspond to the divergence time of at least a few million years, which is unusually large for a human allelic divergence under neutral evolution. We constructed phylog...

ABO genotyping is commonly used in several situations, including blood transfusion, personal identification and disease detection. The present study developed a novel method for ABO genotyping, using loop‑mediated isothermal amplification (LAMP). This method allows the simultaneous determination of six ABO genotypes under 40 min at a constant temperature of 62˚C. The genotypes of 101 blood samp...

In this paper, an attempt is made to apply the African Buffalo Optimization (ABO) to tune the parameters of a PID controller for an effective Automatic Voltage Regulator (AVR). Existing metaheuristic tuning methods have been proven to be quite successful but there were observable areas that need improvements especially in terms of the system's gain overshoot and steady steady state errors. Usin...

The ABO histo-blood group, first discovered over a century ago, is found not only in humans but also in many other primate species, with the same genetic variants maintained for at least 20 million years. Polymorphisms in ABO have been associated with susceptibility to a large number of human diseases, from gastric cancers to immune or artery diseases, but the adaptive phenotypes to which the p...

Athlete burnout (ABO) has been identified as a significant concern among youth sportspeople. Conceptualisations of self, or perspective taking, predict mental health non-athlete adolescents. Consequently, this study aimed to determine how much perspective-taking contributes ABO adolescent athletes. A non-experimental correlational design was employed explore the utility three selves model ABO. ...

BACKGROUND As antigen-specific immunoadsorption (IA) using the Glycosorb®-ABO columns is becoming increasingly popular in ABO-incompatible (ABOi) transplantation, in this study, we retrospectively investigated the efficacy of Glycosorb®-ABO IA in vivo and ex vivo. We also assessed the risk of anti-A/B antibody (ABab) rebound before and after ABOi kidney transplantation. METHODS A protocol for...

Pediatricians have long argued that children are not little adults, and it seems intuitive that clinical practices and regulations should follow appropriately from this paradigm. One can find no better evidence to support this contention than the report by Almond et al1 published in this issue of Circulation. ABO incompatibility has been considered a relative or, by United Network for Organ Sha...

Transfusion of about 60 ml of ABO incompatible plasma in 4 units of pooled platelets precipitated severe haemolysis, unmasking the emergence of paroxysmal nocturnal haemoglobinuria (PNH), in a patient with aplastic anaemia. In vitro tests showed that her red cells were lysed by both ABO compatible and incompatible plasma from normal donors. The behaviour of this case and the in vitro results su...

BACKGROUND ABO blood type incompatibility between a donor and recipient is generally considered a contraindication to kidney transplantation. CASE CHARACTERISTICS A 12-year-old boy presented with end stage renal disease (blood group B), with the only healthy available donor being mother (blood group AB). The child received renal transplant with mother as the donor, with a designed desensitiza...

This a rare case of adenoid hypertrophy in a 23 years old Saudi non-smoker female, who presented with severe bilateral nasal obstruction, mouth breathing, anterior nasal discharge, snoring for the last 7 months. The nasopharynx was examined by flexible nasopharyngoscope, which showed a big mass occupying the nasopharynx. Under general anesthesia, adenoidectomy was performed. Immediately after t...
