BACKGROUND Inflammatory cytokines such as tumor necrosis factor (TNF) have been implicated in the pathogenesis of psoriasis. We evaluated the safety and efficacy of etanercept, a TNF antagonist, for the treatment of plaque psoriasis. METHODS In this 24-week, double-blind study, 672 patients underwent randomization and 652 either received placebo or received etanercept subcutaneously at a low ...

We report the rst detection of a hard power-law tail in the X-ray spectrum of the black hole candidate (BHC) binary X1755-338, which was observed in 1989 March-September during the TTM Galactic Centre survey. In addition, an ultrasoft thermal component with a temperature of 1:1 1:4 keV was also detected. We demonstrate that the soft and hard X-ray components of X1755-338 vary independently, as ...

Photosynthesis, Electron Transport, Chlorophyll Fluorescence, Photosystem II, BAS 13-338 Addition of BAS 13-338 (4-chloro-5-dim ethylam ino-2-phenyl-3(2H )-pyridazinone) to a sus­ pension of chloroplast thylakoids caused an increase in the / level o f chlorophyll fluorescence induction without affecting the F0 level and with a slight decrease in the Fmax level in a manner similar to the additio...
