Introduction: Prostate specific antigen (PSA) is one of the most sensitive markers for diagnosis of prostate cancer. Immunoradiometric kit (IRMA) is a common and sensitive method for determination of PSA in clinical laboratories. This kit has four major components: solid phase coated with monocolonal antibody, pair antibody labelled with I-125, series of standards i...

199 human serum samples were examined for the presence of myxovirus parainfluenza 3 (mpi 3) haemagglutination inhibition (hi) antibodies. or tbe total male sera, 75% and female 70.52% had hi antibody titers of t:32 or greater. the percentage of positive samples increased according to the age grouping of the human beings. these results indicate that mpi 3 virus infection is widespread among the ...

were assayed for recall proliferative response to OVA 323-339. Emulsions prepared by either the dual-syringe or sonification method stimulated a strong T-cell response, as demonstrated by the ex vivo proliferation assay. A likelihood ratio test indicated a stronger immunization with the sonified emulsion transferred by the method outlined above than with the emulsion prepared by the dual-syring...

BACKGROUND During clotting, a thrombin cleaves fibrinogen releasing fibrinopeptide A (FPA). FPA is easily identified in serum using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). Using MALDI-TOF MS, we observed multiple, progressively shorter fragments of serum FPA. Following ambient incubation of serum, variations in the content of FPA fragments ...

To investigate recovirus infections and their association with zoonosis, the prevalence of the virus-neutralizing antibody against three recovirus serotypes was tested in the general population and in zookeepers. Neutralizing antibodies were detected in a significantly higher number of zookeepers than in the general population but with significantly lower titers than in macaques.
