The decolorization potential of textile dye Reactive Red 198 (RR198) by Aspergillus parasiticus fungal biosorbent has been investigated as a function of initial pH, contact time, biosorbent and initial dye concentration in a batch system. Maximum dye biosorption capacity 1.03x10 mol g was observed at pH 2.0 and 2.0 g L of biosorbent concentration. Biosorption equilibrium was attained within 50 ...

The procedure of level optimization for the (198)Hg I spectrum emitted by electrodeless discharge lamps is revisited. Wavelength-measurement uncertainties and systematic shifts caused by interactions with the buffer gas and by calibration procedures are carefully analyzed and accounted for. Based on this extended analysis of the original measurements, the energy levels are re-optimized, which r...

A new species of cloud forest butterfly, Eretris julieta n. sp. is described from a region of south-central Bolivia known as the Elbow of the Andes. It is the southernmost known representative of the genus, hitherto known only from a restricted area of interandean valleys in the department of Santa Cruz. Its affinities with other congeners are evaluated.

Somatization disorder is characterized by the presence of multiple chronic distressing somatic symptoms that are not medically explained. Patients with this condition tend to be highly anxious about their symptoms, even in the face of evidence that their condition is not medically serious. In the draft of the upcoming Diagnostic and Statistical Manual of Mental Disorders (DSM-V), this condition...

Enterohepatic circulation of NY-198 in rats was studied. NY-198 glucuronide in the bile was rapidly hydrolyzed to NY-198 by the intestinal contents. Hydrolyzed and parent NY-198 in the bile were reabsorbed from the intestine. The amount of NY-198 in enterohepatic circulation was 59.8% of that excreted in the bile.

Ar-Benzyladriamycin-14-valerate (AD 198) ¡s a highly lipophilic ana logue of Adriamycin with novel cytotoxic mechanisms, greater in vivo antitumor activity, and the ability to circumvent multidrug resistance due to P-glycoprotein-mediated drug efflux or decreased topoisomerase II activity. To identify the mechanism(s) which may confer AD 198 resist ance, J774.2 mouse macrophage-like cells were...
