Ticlopidine is an agent that inhibits adenosine diphosphate-induced platelet aggregation. Metabolic studies with ticlopidine have indicated that the principal routes of metabolism are N-dealkylation, N-oxidation, and oxidation of the thiophene ring. However, ticlopidine shares some structural features that are similar to those of cyclic tertiary amines such as 1-methyl-4-phenyl-1,2,3,6-tetrahyd...

Water used by mining enterprises needs to be comprehensively recovered and utilized achieve clean production. This requires the effective treatment of mineral processing wastewater. Wastewater produced during non-ferrous metal contains a complex mixture pollutants at high concentrations, making comprehensive difficult. Here, sources hazards posed wastewater are introduced techniques for removin...

Heating oils and fats may lead to cyclization of polyunsaturated fatty acids, as for example linolenic acid. Cyclohexenyl and cyclopentenyl fatty acids are subsequently present in some edible oils and these are suspected to induce metabolic disorders. In a previous experiment using [1-14C] labeled molecules, we published that these cyclic fatty acids are beta oxidized to the same extent as lino...

A carbon paste electrode (CPE) chemically modified with 1-[4-(ferrocenyl ethynyl)phenyl]-1-ethanone (4-FEPEMCPE) was employed to study the electrocatalytic oxidation of L-cysteine using cyclic voltammetry, differential pulse voltammetry and double potential step chronoamperometry as diagnostic techniques. The diffusion coefficient (D = 7.863 x 10(-6) cm2 s(-1)) of L-cysteine was also estimated ...

Although several Prussian Blue analogues (PBAs) have been investigated as water oxidation catalysts, the field lacks a comprehensive study that focuses on the design of the ideal PBA for this purpose. Here, members of a series of PBAs with different cyanide precursors have been investigated to study the effect of hexacyanometal groups on their electrocatalytic water oxidation activities. Cyclic...

In Phaeodactylum tricornutum Photosystem II is unusually resistant to damage by exposure to high light intensities. Not only is the capacity to dissipate excess excitations in the antenna much larger and induced more rapidly than in other organisms, but in addition an electron transfer cycle in the reaction center appears to prevent oxidative damage when secondary electron transport cannot keep...

The reaction of probucol with superoxide (O2(*-)) was investigated in acetonitrile using both electron spin resonance (ESR) and electrochemical techniques. The formation of phenoxyl radical was observed during the reaction of probucol with O2(*-) by ESR spectroscopy. The reaction of probucol with O2(*-) in acetonitrile was followed by cyclic voltammetry. With the addition of probucol, the oxida...

In this work a pack cementation of germanium-doped aluminum and silicon coatings on low alloy steel type-T21 has been applied. This gives significant improvement in the oxidation. Steel-T21 was coated with germanium-doped aluminizing-siliconizing. Diffusion coating was carried out at 1050C for 6 h under an Ar atmosphere by simultaneous germanium-doped aluminizing-siliconzing process. Cyclic oxi...

In order to compare the catalytic activities of reduced graphene oxide (rGO), graphene oxide (GO), and graphene, we conducted oxidation of 2-aminothiophenol (2-ATP) and reduction of nitrobenzene (NB) in their presence by using high-resolution photoemission spectroscopy (HRPES). In addition, we determined conversion rates of CO to CO2 in the presence of these catalysts by performing a residual g...

Antioxidant potential of the fungal dye, produced by a strain selected from the collection of Epicoccum nigrum bioresearch platform (acronym MIUG) was partially characterized in previous studies. However, the fungal dye antioxidant capacity compared with other potential colorant inhibitors of lipid peroxidation (e.g. cochineal dye) has not been fully elucidated, especially regarding its behavio...
