A new hypothesis is discussed, which describes the initiation of the carcinogenesis through polycyclic aromatic hydrocarbons (PAHs) and aminoazo dyes (AZOs) as a two-step process: the oncogenic proteins of the ras or ras-like on-cogenes activated by mutation ("initiation A ") co-operate with the complexes in the plasma membrane formed during the "initiation B " stage from the parent compounds o...

Aromatic azos were synthesized using unsupported ultra-thin platinum nanowires as catalysts under mild reaction conditions and the reaction mechanism was proposed.

During a co-precipitation of cholesterol (Chol) and slight amounts of polycyclic aromatic hydrocarbons (PAHs) or aminoazo dyes (AZOs) in aqueous albumin solution, complex particles are formed; on their surfaces apolipoproteins with an amphipathic alpha-helix (e.g. apoA-I) are more or less firmly adsorbed. An efficacy index can be calculated from the strength of the hydrophobic interactions betw...

Powdery mildew ( Erysiphe necator ) is one of the most common and economically significant diseases grapes. Currently, main method controlling disease pesticide treatment. Breeding resistant varieties necessary to reduce chemical treatments. a number grape resistance genes powdery DNA markers for identification allelic status these are known. In study determine presence loci Ren3 Ren9 , 25 geno...
