Formaldehyde is commonly used in detergents and cosmetic products as antibacterial agent and preservative. This substance is unfavorable for human health because it is known to be toxic for humans and causes irritation of eyes and skins. The toxicology studies of this compound indicate risk of detergents and cosmetic formulations with a minimum content of 0.05% free formaldehyde. Therefore, det...
Recent studies showed that 1,4-dihydropyridine-3,5-dicarbamoyl derivatives with lipophilic groups have significant antitubercular activity. In this study, we have synthesized new derivatives of 1,4-dihydropyridines bearing carbmethoxy and carbethoxy group at C-3 and C-5 of the 1,4-dihydropyridine ring. In addition, 1H-pyrazole ring is substituted at C-4 position. These analogues were synthesize...
ltravioletSpectrometryof Serum Triglyceridesby a TotallyEnzymicMethodAdaptedto a CentrifugalAnalyzer
We describe a mlcromethod for determining serum tiI glycerides (triacylglycerols) with the centrifugal analyzer. Thistechniqueis based on the procedure of Bublitz and Kennedy [J. Blo!. Chem. 211, 951 (1954)J. The enzymic hydrolysis requires 10 mm at 30 #{176}C. Twenty-six serum triglyceride assays can be done in about 30 mm. Concentration and absorbance are linearly related up to 5.0 mmol/llter...
Core@shell electrocatalysts for fuel cells have the advantages of a high utilization of Pt and the modification of its electronic structures toward enhancement of the activities. In this study, we suggest both a theoretical background for the design of highly active and stable core@shell/C and a novel facile synthetic strategy for their preparation. Using density functional theory calculations ...
