CS2 hydrolase, a zinc-dependent enzyme that converts carbon disulfide to carbon dioxide and hydrogen sulfide, exists as a mixture of octameric ring and hexadecameric catenane forms in solution. A combination of size exclusion chromatography, multi-angle laser light scattering, and mass spectrometric analyses revealed that the unusual catenane structure is not an artefact, but a naturally occurr...

ABSTRACT New dimethyl benzoylcarbonohydrazonodithioates were obtained by CS2 addition to arylcarboxylic acid hydrazides and methylation of the formed adduct. The new derivatives were tested for their activity against Mycobacterium tuberculosis. Some compounds exhibited high activity toward sensitive and resistant strains. GRAPHICAL ABSTRACT

A novel synthesis of Iimidazo[1,2-c]quinazoline-5(6H)-thione framework was developed through a three-step reaction starting from benzil. The resulting (2-nitrophenyl)-4,5-diphenyl-1H-imidazole  from the reaction of benzil and different 2-nitrobenzaldehyde, reduction of nitro group and then cyclization reaction with carbon disulfide (CS2). All steps were carried out under easy and user-friendly ...

Screening of absorbents is essential for improving the removal rate carbon disulfide (CS2) waste air by absorption. In this work, UNIFAC model in Aspen Plus was utilized to calculate excess Gibbs function and absorption potential binary system CS2 with various alcohols, ethers, esters, amines, aromatic hydrocarbons. The results were used quantitatively compare efficiency each solvent theoretica...

BACKGROUND Inclined or slippery surfaces and various other types of obstacles are common demands in our environment. Dogs with impaired locomotion might have difficulties to manage rough terrain. Gait analyses using force plates or pressure plates, which are well established to characterize limb loads in human medicine as well as in animals, are mostly limited to level surfaces. Therefore, the ...

OBJECTIVES To improve contact tracing for chlamydia. To determine (i) the acceptability to patients of using a contact slip that named chlamydia as the sexually transmissible infection that the contact may have been at risk of acquiring, and (ii) whether an augmented contact slip issued for chlamydia significantly increased the number of sexual partners attending for treatment. METHODS For a ...
