The binding of Sodium n-dodecyl sulphate (SDS) to histone H3 was studied in the pH range 3.2-10 by equilibrium dialysis at 27? and 3 7 ?c .T he binding data have been used to obtain the Gibbs free energy of interaction using a theoretical model of the Wyman binding potential; and the enthalpy of interaction from the temperature dependence of theequilibriumconstantsfronr theVan't Hoff re1ati...

the thermal denaturation of α-amylase from bacillus amyloliquefaciens has been investigated in the presence and absence of sodium dodecyl sulphate (sds) over the temperature range (293-373) k in 20 mm sodium phosphate buffer, ph 6.9, using temperature scanning spectroscopy. the presence of sds caused the destabilization of α-amylase resulting in a decrease in the temperature of unfolding with a...

BACKGROUND The increased rates of cardiovascular morbidity and mortality in patients with psoriasis are not adequately explained by traditional risk factors. Whether concomitant sleep disorders (SDs) modify the risk of cardiovascular disease (CVD) in patients with psoriasis remains unknown. METHODS Using the Taiwan National Health Insurance Research Database (NHIRD), we conducted a cohort stu...

Endorsement and enactment of the (hetero)sexual double standard (SDS), prescribing sexual modesty for girls and sexual prowess for boys, has been shown to be negatively related to sexual and mental health. To be able to challenge the SDS, more insight is needed into the conditions that shape gendered sexual attitudes. A survey was conducted among 465 heterosexual adolescents (aged 16-20 years),...

Introduction: Skin diseases (SDs) are one of the most common health problems in Nepal. The objectives of this study are to determine the prevalence of SDs and impact on quality of life (QoL) in a rural community in Nepal. M ethods: A house-to-house survey was conducted in a community with 3,207 inhabitants, to obtain socio-demographic data and identify individuals with SDs. Free examination and...

A novel method for the on-column sample stacking of proteins is described. The strategy takes advantage of interactions between protein molecules and sodium dodecyl sulfate (SDS) monomers. A long plug of a protein sample (either acidic or basic) is injected into a capillary filled with a background electrolyte (BGE) containing SDS. When a potential is applied, the proteins interact with SDS mon...

Polymer-surfactant interactions in aqueous solutions of a hydrophobically modified polymer, poly(maleic acid/octyl vinyl ether) (PMAOVE), with sodium dodecyl sulfate (SDS) were studied using surface tension, viscosity, electron paramagnetic resonance spectroscopy, and fluorescence spectroscopic techniques. When the anionic surfactant SDS was added to the aqueous solutions of the similarly charg...

The amyloid β (A β) peptide is important in the context of Alzheimer's disease, since it is one of the major components of the fibrils that constitute amyloid plaques. Agents that can influence fibril formation are important, and of those, membrane mimics are particularly relevant, because the hydrophobic part of A β suggests a possible membrane activity of the peptide. We employed spin-label E...

The solubilization dynamics of dimyristoylphosphatidylcholine (DMPC) liposomes, as induced by sodium dodecyl sulfate (SDS), were investigated; this investigation was motivated by several types of atypical behavior that were observed in the solubilization in this system. The liposomes and surfactants were mixed in a microchip, and the solubilization reaction of each liposome was observed using ...
