BACKGROUND ABO blood typing in pre-transfusion testing is a major component of the high workload in blood banks that therefore requires automation. We often experienced discrepant results from an automated system, especially weak serum reactions. We evaluated the discrepant results by the reference manual method to confirm ABO blood typing. METHODS In total, 13,113 blood samples were tested w...

BACKGROUND Erythrocyte-magnetized technology (EMT) is a new fully automated method for ABO-RH-K phenotyping and antibody detection. The magnetization of red cells avoids centrifugation and washing phases. This report describes the results of an evaluation of this new technology on its specific automated system. STUDY DESIGN AND METHODS ABO-RH-K phenotyping was compared between EMT and a semia...

BACKGROUND Although the relationship between non-O blood types and the risk of exocrine pancreatic cancer has been demonstrated, the association between ABO blood types and sporadic pancreatic neuroendocrine tumor (PNET) has not been reported thus far. METHODS This hospital-based, case-control study included 387 patients with PNET and 542 age- and sex-matched controls. Unconditional multivari...

In the fall of 2001, the American Board of Orthodontics (ABO) began a committed discussion of early certification after graduation from a recognized orthodontic training program. The board’s intention was 2-fold: to evaluate the possibility of offering early certification to recent graduates by using cases treated during their residencies, by determining whether resident treatment quality could...

Blood group antigens of the H, ABO, Lewis, and historical “P” blood groups are defined by small carbohydrate epitopes expressed as posttranslational modifications on glycoproteins, mucins, and glycolipids. Their synthesis is complex and dependent on several distinct glycosyltransferases and interrelated biosynthetic pathways. In many cases, carbohydrate antigens share features of more than one ...

Drosophila melanogaster females homozygous for the abnormal oocyte mutation produce a large excess of female offspring when crossed with XY/0 males. After several genera­ tions in abo homozygous stock, this maternal effect is no longer observed. The disappearance of the abo phenotype is coupled with an increase in the amount of DNA coding for rRNA (rDNA). We have used restriction endonuclease a...

Background and Aims: Due to the shortage of donor livers, minor ABO-incompatible liver transplantations are commonly performed. Together with the allograft, immunocompetent B-lymphocytes, called passenger lymphocytes, are transplanted. In case of minor ABO-incompatibility, these passenger lymphocytes produce antibodies directed towards the recipient's red blood cells, which causes immune-mediat...

Background: The ABO blood group system was the first human blood group system to be discovered by Landsteiner in 1900. The second type of blood group is the rhesus system. There are only two Rh phenotype such as Rh positive and Rh negative, depending on whether Rh antigen is present on the red cell or not. The frequency of ABO and Rh phenotypes in different populations has been extensively stud...

From June 1982 to November 1989, 39 ABO-incompatible living kidney transplants were performed in 38 recipients. Pretransplant therapies included platelets donor transfusion (21/39), 2 to 5 plasmapheresis sessions (39/39), cyclosporin A with or without azathioprine (33/39) along with polyclonal Abs (36/39) and splenectomy at the time of transplantation (37/39). The last patient who received 2 AB...

The Public Wireless Local Area Network (PWLAN) is an emerging service for wireless access to the Internet. However, the service coverage of the PWLAN is limited by the deployment of access points (APs) because only those who stay near the AP can access the PWLAN. A feasible way of extending the service coverage of a PWLAN is to deploy mobile ad hoc access networks (MAHANs) so that users who are...
