the leishmania major parasite surface antigen-2 (psa-2) is a family of glycoinositol phospholipids anchored glycoprotoins expressed in both promastigotes and amastigotes. promastigote psa-2 comprises three polypeptides with approximate molecular weight of 96, 80 and 50 kda. amastigote express a distinct but closely psa-2 polypeptide with molecular weight of 50 kda. in this study fusion of sp2/0...

INTRODUCTION Prostate-specific antigen (PSA) is a widely used tumor marker in the detection and follow-up of adenocarcinoma of the prostate. Selection of candidates for prostate biopsies is hampered by the lack of specificity resulting in a large number of unnecessary biopsies. The intention of our study was to compare the percent free PSA (f-PSA; Hybritech Tandem-R) with total PSA and age-spec...

background prostate is an important male reproductive system gland and its disorders can affect men's quality of life and health. prostatitis, benign prostatic hyperplasia (bph), and prostate adenocarcinoma are major disorders that can be found in all men in different ages. objectives the aim of this study was to investigate the association of diet with serum prostate specific antigen (psa) lev...

The landscape of prostate cancer has changed since the appearance of the first prostate-specific antigen (PSA) assay. PSA testing has gained rapid recognition since M. Kuriyama et al. (1 ) of Roswell Park first reported clinical studies using an enzyme immunoassay with anti-PSA rabbit antibody. Mikolajczyk and coworkers (2, 3) reported the presence of several free PSA isoforms and the potential...

In the quarter-century since its discovery (1 ), prostatespecific antigen (PSA) has been recognized as the most effective tumor marker for prostate cancer and has unquestionably played an important role in the diagnosis and clinical management of this disease. Prostate cancer remains the leading cancer site in men, with 179 300 new cancer cases estimated by the American Cancer Society for 1999,...
