Prostate specific antigen (PSA) testing is now a routine part of the investigation of men with suspected prostate cancer. While a very useful test it still has its problems, in particular its lack of specificity means abnormal results are often caused by benign disease. This review describes the current problems with PSA testing in prostate cancer diagnosis and highlights potential ways in whic...
We report the first use of a commonly used ELISA colorimetric substrate as a SERRS marker and show how it can be used for the detection of pg ml(-1) levels of human prostate specific antigen (PSA) in clinical samples. The technique is amenable over a wide range of concentrations and lends itself to future multiplexing analysis.
AIM To review current data available on use of prostate specific antigen for screening healthy men for prostate cancer. METHODS Literature was reviewed and the guidelines from, American cancer Society, American Urologic Association was reviewed. RESULTS Current screening protocols lead to over diagnosis of prostate cancer. This often results in unnecessary biopsy procedures and treatments. ...
Background. The use of prostate-specific antigen test has markedly increased in Danish general practice in the last decade. Despite the national guidelines advice against PSA screening, opportunistic screening is supposed to be the primary reason for this increased number of PSA tests performed. Aims. Based on the increase in the amount of PSA conducted, we aimed to analyse how GPs in Denmark u...
The sip gene encoding for a conserved highly immunogenic surface protein of Streptococcus agalactiae was amplified using polymerase chain reaction (PCR) and subcloned into prokaryotic expression vector pET32a (+) and expressed as a recombinant protein in E. coli BL21 (DE3). An indirect enzyme linked immunosorbent assay (ELISA) was developed using the purified Sip protein as a coating antigen, w...
objective: hepatitis c virus (hcv) is one of the most relevant persistent infections afflicting the human population. control of viral replication in hcv infection has been associated with the cellular component of the host immune response. several mechanisms have been proposed to explain this abnormal immune response, among them an altered activity of regulatory t cells (tregs) being the most ...
Background: The therapy of leishmania infection is difficult and each year 1.5 million new cases of cutaneous leishmaniasis and 500,000 new cases of visceral leishmaniasis are estimated, therefore, there is a need for an effective vaccine. Monoclonal antibody (mAb) is one of the suitable methods for isolation and purification of leishmania antigens. In this report, we produced several mAb aga...
