OBJECTIVE To examine the feasibility of fetal RHD genotyping at 11-13 weeks' gestation from analysis of circulating cell-free fetal DNA (ccffDNA) in the plasma of RhD negative pregnant women using a high-throughput robotic technique. METHODS Stored plasma (0.5 ml) from 591 RhD negative women was used for extraction of ccffDNA by a robotic technique. Real-time quantitative polymerase chain rea...
The Rh blood group antigens derive from 2 genes, RHD and RHCE, that are located at chromosomal position 1p34.1-1p36 (chromosome 1, short arm, region 3, band 4, subband 1, through band 6). In whites, a cde haplotype with a deletion of the whole RHD gene occurs with a frequency of approximately 40%. The relative position of the 2 RH genes and the location of the RHD deletion was previously unknow...
Rabies virus nucleoprotein (N protein) encapsidates genomic RNA of the virus and forms the viral ribonucleoprotein complex. These N proteins represent highly organized structures which activate proliferation of B cells and production antibodies against the N protein. In addition to the B cell, the rabies virus N protein has been shown to induce potent T helper cell responses resulting in a long...
Background and Objective: Of all blood group systems, RH is one of the most important blood groups, which its compatibility is one of the essential principals of transfusion. Two genes (RhD and RhCE) locate on chromosome 1, and encode the Rh proteins. RhD is an immunogenic antigen. We describe a rare Rh phenotype D-- in this report. Case Report: A forty- nine- year- old man, who receiv...
We propose Remote Harm-Diagnostics (RHD) as a new defensive tactic against malware and phishing attacks. RHD is a server-side tool that harvests data from clients to detect signs of previous or ongoing compromise. RHD can supplement client-side protections such as virus checkers and anti-phishing toolbars. Given its “soft,” i.e., probabilistic nature, RHD interfaces naturally with risk-based au...
OBJECTIVES To assess the feasibility of applying a high throughput method, with an automated robotic technique, for predicting fetal RhD phenotype from fetal DNA in the plasma of RhD negative pregnant women to avoid unnecessary treatment with anti-RhD immunoglobulin. DESIGN Prospective comparison of fetal RHD genotype determined from fetal DNA in maternal plasma with the serologically determi...
BACKGROUND Rhesus-positive and rhesus-negative persons differ in the presence-absence of highly immunogenic RhD protein on the erythrocyte membrane. This protein is a component of NH(3) or CO(2) pump whose physiological role is unknown. Several recent studies have shown that RhD positivity protects against effects of latent toxoplasmosis on motor performance and personality. It is not known, ho...
Objective(s): Helicobacter pylori, a human specific gastric pathogen is a causative agent of chronic active gastritis. The vacuolating cytotoxin (VacA) is an effective virulence factor involved in gastric injury. The aim of this study was to construct a recombinant protein containing antigenic region of VacA gene and determine its antigenicity. Materials and Methods: The antigenic region of V...
Rozrolimupab, a recombinant mixture of 25 fully human RhD-specific monoclonal antibodies, represents a new class of recombinant human antibody mixtures. In a phase 1 or 2 dose escalation study, RhD(+) patients (61 subjects) with primary immune thrombocytopenia received a single intravenous dose of rozrolimupab ranging from 75 to 300 μg/kg. The primary outcome was the occurrence of adverse event...
We evaluated the efficacy of noninvasive fetal Rhesus D (RHD) genotyping from maternal plasma in a highly admixed population. Fifty-five blood samples from RhD-negative pregnant women from Brazil were processed for extraction of cell-free plasma DNA. Real-time PCR was performed to amplify segments of exons 5 and 7 from the RHD gene, as well as for detection of the SRY gene to confirm the presen...
