The human blood group Rh antigens are expressed by proteins encoded by a pair of highly homologous genes located at chromosome 1p34-36. One of the genes (RHCE) encodes Rh CcEe antigens, while the other (RHD) the D antigen. Point mutations in the RHCE gene generate the C/c and E/e polymorphisms, while it has been shown that an RHD gene deletion can generate(More)

OBJECTIVE To test the hypothesis that free fetal DNA (ffDNA) circulating in maternal plasma originates mainly from the placenta we studied ffDNA levels in anembryonic pregnancies. METHODS Maternal blood samples were collected from 15 normal first-trimester pregnancies in which fetal sex was subsequently determined and nine patients with a diagnosis of(More)
The purpose of this study was to investigate the sensitivity of orientation and recent memory questions in the diagnosis of concussion. In a prospective study over 7 consecutive years (1985-1991), all players at a professional Australian Rules Football club who sustained a concussive injury (n = 28) were administered a set of questions evaluating(More)
AIM To critically review the evidence to determine the efficacy and effectiveness of protective equipment, rule changes, neck strength and legislation in reducing sport concussion risk. METHODS Electronic databases, grey literature and bibliographies were used to search the evidence using Medical Subject Headings and text words. Inclusion/exclusion(More)
There are significant merits to a comprehensive cognitive assessment, but they are also time-consuming, costly, and susceptible to practice effects and may not detect change in the context of medical interventions or minor brain disruptions. Brief computer-based assessments focused on "fluid" cognitive domains (e.g., information-processing skills), which(More)
Hairy roots of Brassica napus (rape cv. Giant) were produced by cocultivating leaf and cotyledon explants with Agrobacterium rhizogenes strain A4T. The hairy roots grew prolifically on solid and in liquid media. Incorporation of ammonium sulphate or phosphinothricin (PPT) into the media reduced growth. PPT treatment reduced glutamine synthetase (GS)(More)
