A starch-degrading enzyme produced by the yeast Cryptococcus sp. S-2 was purified in only one step by using an alpha-cyclodextrin-Sepharose 6B column, and was characterized as an alpha-amylase (EC 3.2.1.1). The molecular mass and isoelectric point of purified alpha-amylase (AMY-CS2) were estimated to be 66 kDa and 4.2 respectively. AMY-CS2 has raw-starch-digesting and raw-starch-absorbing activ...

The tris(pentafluoroethyl)silanide anion adds to carbonyl compounds Ph(R)CO (R=Ph, H), CS2, and CO2, allowing the isolation of novel negatively charged species like [Si(C2F5)3(η2-OC(R)Ph)]− [Si(C2F5)3(η2-CS2)]−, [Si(C2F5)3(η2-CO3)]−. Details reactions are described by Berthold Hoge et al. in their Research Article on page 12124.

We use nonlinear beam deflection to separate the bound-electronic and nuclearrotational responses in gas-phase CS2. This allows a direct comparison of the second hyperpolarizability to our liquid CS2 measurements considering local-field effects. OCIS codes: (190.0190) Nonlinear optics, (190.3270) Kerr effect, (190.5650) Raman effect, (350.3250) Isotope separation

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...

Enterotoxigenic Escherichia coli (ETEC) strains are leading causes of childhood diarrhea in developing countries. Adhesion is the first step in pathogenesis of ETEC infections and ETEC pili designated colonization factor antigens (CFAs) are believed to be important in the biofim formation, colonization and host cell adhesions. As a first step, we have determined the biofilm capability of ETEC e...

OBJECTIVE The aim of this prospective study was to assess the dynamics of oxidative stress during coronary artery bypass surgery with cardiopulmonary bypass. METHODS Sixteen patients undergoing coronary artery bypass grafting were enrolled. Blood samples were collected from the systemic circulation during anesthesia induction (radial artery--A1), the systemic venous return (B1 and B2) four mi...

The concentration of plasma free fatty acids in rats was significantly increased after a short period of exposure to inhalation of carbon disulphide (4 h, 2 mg/1). In contrast, after a longer period of exposure (15 h overnight, 2 mg/1) the concentration of plasma free fatty acid was significantly decreased despite a small hypoglycaemia. At the same time plasma urea concentration was significant...

Carbon disulfide is a volatile organic solvent currently used in large amounts only in the viscose industry. The negative effects of occupational exposure to CS2 on health parameters have been described at length. Despite the abundant literature, several contradictions remain unsolved, the doseeffect relationship being poorly understood. The prime reason for this is the lack of exposure measure...

Carbon disulfide (CS2) is a typical organic sulfur compound emitted from many industrial processes, such as petrochemical, smelting, et al. Chemical adsorption promising method for CS2 removal and Fe based adsorbents usually show excellent performance. Single-atom catalysts (SACs) always perform magical effects in various heterogeneous reactions. In this work, pyrolyzing coordinated polymer (PC...
