The interaction of histone H2B and dodecyl trimethyl ammonium bromide (DTAB) was studies via equilibrium dialysis method at two different temperatures, at pH 6.4 in phosphate buffer. The binding data were used to obtain the Gibbs free energy of interaction, which is interpreted in terms of a theoretical model based on the Wyman binding potential. The data were then used to obtain...

La presencia de contaminantes emergentes, como los antibióticos, representa una gran preocupación debido a efectos que causa en ecosistemas y la salud humanos. El mayor impacto este tipo es resistencia bacteriana medios naturales, principalmente el agua, aunque existen métodos para removerlos, las trazas antibióticos no pueden ser retiradas completamente por plantas tratadoras aguas residuales ...

interaction between dna and histone h, was investigated in the presence and absence of sodium-n-dodecyl sulphate (sds) and dodecyl trimethylammonium bromide (dtab) at temperatures of 27 and 37?c, in 2.5 mm phosphate buffer, ph 6.4 by uv spectrophotometry, equilibriumdialysis and titration. the presence of 1.33 mm sds caused histone h to fold and to further contact dna. binding data were used in...

Chelating agents’ application for EOR and well stimulation is fast growing nowadays. However, reagents of this class have some drawbacks, with high values interfacial tension (IFT) being among them. IFT may be lowered the addition surfactants; however, simultaneous chelating agents surfactants has not yet been widely studied. This paper focuses on experimental theoretical investigation interact...

White Spot Disease (WSD) is a viral disease affecting crustaceans. Caused by the Syndrome Virus (WSSV), this has caused significant mortality in commercially cultivated marine shrimp species with severe impacts on farming industry and may be threat to wild stocks. Thorough studies molecular biology of pathogen are urgently needed improve understanding virus at level, including variation key pro...
