Behçet's disease (BD) is a systemic vasculitis with unclear etiology and pathogenesis. Although several viral and bacterial causes have been investigated in detail for several years, of late it is widely accepted that microorganisms may play a role as a trigger, or as a cross-reactive antigens that interfere with self-antigens, such as heat-shock proteins.(More)
We assessed the role played by the ERAP1 gene in Turkish patients with ankylosing spondylitis (AS) in terms of disease susceptibility, clinical manifestations, and disease severity. We included 150 consecutive AS patients who met the modified New York classification criteria and 150 healthy controls. We documented the presence of 10 ERAP1 single-nucleotide(More)
The objective of this study has been the well established fact that proinflammatory cytokines and metalloproteinases play a crucial role in the pathogenesis of chronic arthritis as well as the development of pannus, with the eventual erosive changes. Among the proinflammatory cytokines, interleukin-18 (IL-18) has been shown to contribute to the pathogenesis(More)
Considerable discrepancies exist in the literature with respect to plasma total homocysteine (tHcy) levels in Behçet's disease (BD). The aim of this study was to evaluate tHcy concentrations in these patients. Thirty-two patients with BD and 20 age- and body mass index-matched healthy volunteers were enrolled. Plasma tHcy concentrations were significantly(More)
OBJECTIVE To test contrast to noise ratios (CNRs) of both diffusion-weighted (DW) images and contrast enhanced images in terms of the visual assessment of activity in sacroiliitis of ankylosing spondylitis (AS) patients. MATERIALS AND METHODS The study included 21 patients with AS. All patients were examined with STIR, FST1/Gd and DWI (b = 0,600). A total(More)
The activity of adenylate cyclase in striatal membrane-enriched fractions (25,000 g) was inhibited by morphine, beta-endorphin, [D-Ala2-D-Leu5] enkephalin (DADLenk), fentanyl and bremazocine. Whereas guanosine triphosphate (GTP) appeared essential for the expression of this effect, sodium chloride seemed to enhance the degree of inhibition. Dopamine(More)
OBJECTIVE To evaluate whether basal levels of circulating cytokines and selectins exhibit a distinct profile in attack-free, non-colchicine taking familial Mediterranean fever (FMF) patients compared to normal healthy controls, and to determine the effect of colchicine treatment on these parameters. METHODS Serum levels of interleukin (IL)-6, IL-8, tumor(More)
Th1 type polarization has been implicated in the pathogenesis of familial Mediterranean fever (FMF). Interleukin-12 (IL-12) and IL-10 are proinflammatory cytokines, which play crucial role in Th1 and Th2 type immune response, respectively. IL-18 has a dual effect on T cell response: it was recognized as an IFN-gamma-inducing factor in T cells; acting in(More)
Adult-onset Still's disease (AOSD) has often been regarded as the adult spectrum of systemic juvenile idiopathic arthritis (sJIA). The present study aims to compare the clinical and laboratory features, the disease course and the response to treatment in patients having AOSD with those having sJIA. Retrospective review of all available data that were filled(More)
Chronic administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced parkinsonian symptoms, predominantly bradykinesia and tremor, in marmosets. These symptoms were reduced by L-DOPA plus benserazide but the putative D1-receptor agonist SKF 38393-A did not affect tremor and increased the bradykinesia. Neither treatment affected behaviour in(More)
