BACKGROUND Remodeling of the extracellular matrix plays an important role during the pathogenesis of atherosclerosis and restenosis. The matrix glycoprotein thrombospondin-1 (TSP1) inhibits endothelial cell proliferation and migration in vitro. In contrast, TSP1 facilitates the growth and migration of cultured vascular smooth muscle cells. Accordingly, we investigated the hypothesis that admini...

Solitary fibrous tumors (SFTs) have been shown to harbor the characteristic NAB2-STAT6 gene fusion. Some recent studies have suggested that STAT6 is a useful marker for the diagnosis of SFTs. The aim of this study was to evaluate the diagnostic value of monoclonal anti-STAT6 in the distinction of SFTs from histologic mimics. The expression of STAT6 was evaluated in tissue microarrays and in who...

Background and Objectives: Vaccination is the major strategy to protect nurses against infection with hepatitis B virus. However, some nurses do not produce sufficient amount of anti-HBsAg antibody required for immunity against infection. Chronic occupational stress has been proposed as a risk factor to humoral immunity. Given that nursing staff is exposed to occupational stress risk, this stud...

Gp210 is a major transmembrane glycoprotein associated with the nuclear pore complex that is suggested to be important for organizing pore complex architecture and assembly. A mouse monoclonal IgG directed against an epitope in the lumenal domain of rat gp210 was expressed in cultured rat cells by microinjection of mRNA prepared from a hybridoma cell line. The expressed IgG, which becomes assem...

The present study was planned to evaluate correlation between Helicobacter pylori (HP) infection and autoimmune liver disease (AILD). A total of 60 patients diagnosed with AILD in Affiliated Hospital of Binzhou Medical College were continuously enrolled in the present study. HP infection was detected by 13C-urea breath test. The levels of anti-myeloperoxidase were tested by ELISA. The positive ...

The distribution of U1, U2, U4, U5 and U6 small nuclear ribonucleoproteins (snRNPs) and interchromatin granules (IGs) was studied by electron-microscopic immunocytochemistry (EMI) in early 2-cell mouse embryos at the onset of embryonal transcription. The localization of these antigen structures was evaluated with respect to nucleoplasmic ribonucleoprotein (RPN) regions consisting of interchroma...

Background and aim: An epidemiological association of lichen planus (LP) with hepatitis C virus (HCV) infection has been found only in certain parts of the world and in some countries no association has been noted. The present study was done to evaluate the association of LP with HCV in patients admitted to Sina hospital, Hamedan, Iran from 2002 to 2004.Materials and Methods: The presence of an...

The development of glomerulonephritis in NZB/W mice is closely related to the formation of antinuclear, particularly anti-DNA, antibodies. The developing inflammatory glomerular lesions are characterized by the deposition of gammaG- and beta(1C)-globulins plus DNA and possibly other nuclear antigens, presumably as complexes, in a granular to lumpy pattern along the capillary walls and in the me...
