BACKGROUND/AIMS Little is known about the anti-colitis effect of tryptophan or its metabolites. Here, the protective effect and its mechanism of tryptophan administration on dextran sulfate sodium -induced colitis in mice was studied. MATERIALS AND METHODS Twenty C57black6 female mice were equally divided into the control group, and treatment group. The control group received a standard CE-2 ...

A modified filmadsorber is presented, intended to be used for selective and specific hemoperfusion. It consists of a spirally wound cellulose nitrate film, onto which--after chemical activation with sodium periodate--albumin is bound, stabilized, sterilized and activated with glutaraldehyde. Various bioactive ligands containing amino groups can be coupled to this support. A subsequent treatment...

Hydroquinone (HQ) was used as the principal chemical reducing agent to prepare aqueous silver nanocolloids from silver nitrate. The data demonstrate that HQ is unable to initiate the particle growth process on its own, but is able to sustain particle growth in the presence of pre-existing metallic clusters. This unique selectivity is similar to that seen in photographic systems. Data are presen...

The opportunistic pathogen Burkholderia pseudomallei is a saprophytic bacterium and the causative agent of melioidosis, an emerging infectious disease associated with high morbidity and mortality. Although melioidosis is most prevalent during the rainy season in endemic areas, domestic gardens and farms can also serve as a reservoir for B. pseudomallei during the dry season, in part due to irri...

the hydrolysis of cadmium nitrate was studied spectrophotometrically at different ionic strengthsof sodium perchlorate in a wide ph range, 1-12, and at 25 c. least squares calculations areconsistent with the formation of m(oh)+, m(oh)2, m(oh)3- and m(oh)42- species, which m iscd2+. the dependency on ionic strength in the background electrolyte solutions was taken intoaccount by using a debye-hu...

Deep ultraviolet Raman spectroscopy measurements have been performed at the German Aerospace Center (DLR) with aim of detecting traces (μg range) explosive precursors. In this study, a backscattering system was setup and optimized to detect urea, sodium perchlorate, ammonium nitrate, nitrate 60-cm short-range remote detection. The sample tested 264-nm laser excitation wavelength experimentally ...
