Agha S, El-Mashad N, El-Malky M, El-Shony H, El-Sherif MZ, El-Hasan MA, Tanaka Y, Mizokami M: Prevalence of low positive anti-HCV antibodies in blood donors: Schistosoma mansoni co-infection and possible role of autoantibodies. Microbiol Immunol 2006, 50 (6) : 447–452....
Tests on 10 clinicalblood samplesinvolved incubating patient plasma or serum with redbloodcells previously coated with short peptides representing pieces of the SARS-CoV-2 virus. If the patient sample contained antibodies against SARS-CoV-2, these antibodies would bind to peptides and result in agg...
Antibodies circulating in a person's blood normally recognize the antigens in that same person's blood cells and don't react with them. However, if a person with one blood type is given blood of another type, the antibodies bind to the foreign antigens, causing clumping of the blood and...
The hepatitis C virus has been identified as the main cause of post- transfusion hepatitis.1 Mandatory screening of blood donations for antibodies to hepatitis C virus was introduced by the National Blood Transfusion Service on 1 September 1991. Donors confirmed to be positive for antibodies to hep...
The blood recipient who have been transfused time after time all had high positive rate of irregular antibodies and direct antibodies.It could effectively reduce or avoid hemolytic transfusion reaction by conventional antibody screening test among the blood recipient,which was propitious for early ...
The effect of intravenous administration of 3,4-methylendioxymethamphetamine (MDMA), in a range of doses (0.32-3.2 mg/kg) that have been shown to maintain self-administration behaviour in rats, on in vivo acetylcholine release from rat prefrontal cortex and dorsal striatum was studied by means...
surface antibody positive stimulation of antibody titer reached more than 10, most can play a protective role in 8-10, and often with hepatitis B patients contact person although antibody offset faster, but because the trace of hepatitis B virus stimulation, the body may also produce antibodies....
BACKGROUND: All donated blood in Israel is tested for anti-hepatitis C virus (HCV) antibodies by enzyme immunoassay (EIA) and donors are notified of the result. There is evidence that at low antibody titres, the percentage of false positives may be high, with consequent labelling of healthy ...
Detection of antibodies to human T-lymphotropic virus type 1 (HTLV-1) Sera from 39,898 blood donors were tested for HTLV-1 antibodies using two enzyme immunoassays (EIA). Sera testing initially reactive (IR) were retested in duplicate by both EIAs. Sera testing repeatedly reactive (RR) were...
Our aim was to study the characteristics of blood donors with serum anti-HCV antibodies, their medical follow-up based on a questionnaire, and the follow-up of their recipients who were transfused before systematic screening of anti-HCV antibodies had begun. From March 1990 to January 1992, 25...
