The effects of toluene on lipid peroxidation and rates of reactive oxygen species (ROS) formation have been studied in isolated systems and in vivo. The induction of reactive oxygen species was assayed using the probe 2',7'-dichlorofluorescin diacetate (DCFH-DA). Toluene exposure (1 g/kg, 1 hr, i.p.) did not stimulate cortical lipid peroxidation as evaluated by measurement of conjugated dienes....

Metal Binder Jetting emerged and it has been developing an additive manufacturing method. type, binder ratio, sintering process, atmosphere couldn’t be transparently determined due to its development stage. In this study, effect of temperature was investigated parts’ microstructure which manufactured by Additive Manufacturing. manufacturing, SS316L metal powder used as a raw material, ultraviol...

Hammett constants (σ) can be important factor to understanding substitution and position effects on benzoic acid. This report describes a computational study of ∆G◦ and σ for six substituted benzoic acid (X= F,Cl ,OH ,NH2 ,CN,NO2 )and phenylacetic acid substituted (X=OH ,NH2 ) at para and meta positions ingas and aqueousphases by DFT method and comparesit to available experimental and theoretic...

A para-terphenyl diphosphine was employed to support a dipalladium(I) moiety. Unlike previously reported dipalladium(I) species, the present system provides a single molecular hemisphere for binding of ligands across two metal centers, enabling the characterization and comparison of the binding of a wide variety of saturated and unsaturated organic molecules. The dipalladium(I) terphenyl diphos...

Proteins required for the synthesis of peptidoglycan and incorporation of diaminopimelic acid into cell walls have been solubilized from Bacillus megaterium toluene-treated cells. Some of these proteins might have been removed from the cytoplasmic membrane through the cell wall by extraction with LiCl. The solubilized proteins have molecular weights in the range of 40,000 to 70,000 and can be a...

Considerable interest has been aroused recently in the investigation of substances which inhibit the action of the sulfonamide drugs. Lockwood (1) showed that peptones inhibit the action of sulfanilamide on streptococci. Stamp (2) isolated certain fractions of streptococci, and Green (3) isolated fractions of brucella, which have similar activity with respect to the corresponding organisms. Wes...

Hippuric acid is the primary metabolite of toluene, a solvent widely used in industrial processes with considerable toxic effects, a fact which justifies regularly monitoring individuals with occupational exposure to this solvent. This work aims at evaluating urinary hippuric acid levels found in workers subject to biological monitoring. A retrospective study was carried out with data referring...
