INTRODUCTION Behçet's disease (BD) as systemic vasculitis of unknown etiology is associated with HLA-B*51 in European and Asian populations. HLA-A*26 was claimed as an additional BD susceptibility marker in Japanese and Greek patients. This study was performed to test for HLA associations in HLA-B*51 negative German and Turkish BD populations. METHODS In total, 65 German and 46 Turkish patien...

OBJECTIVES While remission is achieved in the majority of Wegener's granulomatosis (WG)-patients with cyclophosphamide, maintenance of remission remains a challenge due to the high rate of relapses. The purpose of this study was to evaluate the safety and efficacy of the combination of methotrexate (MTX) plus leflunomide (LEF) for the treatment of minor relapsing WG not warranting cyclophospham...

We present the first observations of the circumstellar (CS) disk system 51 Ophiuchi with the Far Ultraviolet Spectroscopic Explorer. We detect several absorption lines arising from the unusual metastable atomic species N I (D), N I (P ), and S II (D). These levels lie 1.8 – 3.6 eV above the ground level and have radiative decay lifetimes of 2 days or less, indicating that the lines arise from w...

In the folding of bovine pancreatic trypsin inhibitor (BPTI), the single-disulfide intermediate [30-51] plays a key role. We have investigated a recombinant analog of [30-51] using a 2-dimensional nuclear magnetic resonance (2D-NMR). This recombinant analog, named [30-51]Ala, contains a disulfide bond between Cys-30 and Cys-51, but contains alanine in place of the other cysteines in BPTI to pre...

the color removal of three reactive dyes in an aquatic system without priortreatment was studied. selected commercial dyes were treated with nac102 anduv as oxidation agents. effects of nature of oxidant, temperature, ph ofsolutions, concentration of c107—, contact time of c102— and uv irradiation wereinvestigated. optimal c102— concentration for color removal in the absence of uvirradiation wa...
