BACKGROUND Celiac disease (CD) is an intestinal inflammatory condition that develops in genetically susceptible individuals after exposure to dietary wheat gliadin. The role of post-translational modifications of gliadin catalyzed by tissue transglutaminase (tTG) seems to play a crucial role in CD. However, it remains to be established how and where tTG is activated in vivo. We have investigate...

OBJECTIVES To assess the long-term sexual potency and attrition in sexual function after iodine-125 ((125)I) seed radiotherapy and the effect of sildenafil on radiation-induced erectile dysfunction (ED). METHODS This prospective study consisted of 86 sexually active patients (mean age 63.5 +/- 7.7 years) who underwent (125)I seed implantation from 1997 to 1999 to treat low-volume prostate can...

Accurate and timely diagnosis of dengue virus (DEN) infections is essential for the differential diagnosis of patients with febrile illness and hemorrhagic fever. In the present study, the diagnostic value of a newly developed immune-complex dissociated nonstructural-1 (NS-1) antigen dot blot immunoassay (DBI) was compared to a commercially available DEN antigen detection kit (denKEY Blue kit; ...

The present study was an attempt to raise hen egg yolk Ig (IgY) simultaneously directed against Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) in the same egg yolk. The immunopotentiating effect of 2 different adjuvants -- Freund's adjuvants (FA) and immunostimulating complexes matrix (IM) -- on antibody response was also evaluated. Bacterial outer membrane proteins (OMP) were sele...

introduction: recent studies have shown that astrocytes play major roles in normal and disease condition of the central nervous system including multiple sclerosis (ms). molecular target therapy studies in ms have revealed that connexin-43 (cx43) and aquaporin-4 (aqp4) contents of astrocytes undergo expression alteration. fluoxetine had some effects in ms patients unrelated to its known antidep...

A solid-phase radioimmunoassay (RIA) procedure was compared with the indirect fluorescent antibody (IFA) test in a serological study of 76 female adults with urinary tract infections. Relative serum antibody activity was determined against patients' homologous infecting enterobacteria by RIA and IFA and against heterologous enterobacterial common antigen (Escherichia coli O14) by RIA. There was...

Paracoccidioides brasiliensis and P. lutzii are fungi that cause paracoccidioidomycosis (PCM), the most prevalent systemic mycosis in South America. For serological diagnosis, although 43-kDa glycoprotein (gp43) is regarded as highly specific for PCM, the occurrence of false negative reactions in sera from patients infected with P. lutzii suggests that preparation with only one antigen is not r...

Four-color flow cytometry was used with a cocktail of antibodies to identify and isolate CD34+ hematopoietic progenitors from normal human peripheral blood (PB) and bone marrow (BM). Mature cells that did not contain colony forming cells were resolved from immature cells using antibodies for T lymphocytes (CD3), B lymphocytes (CD20), monocytes (CD14), and granulocytes (CD11b). Immature cells we...
