Dynamic modification of poly(dimethylsiloxane) channels using a mixture of n-dodecyl-beta-D-maltoside (DDM) and sodium dodecyl sulfate (SDS) is able to suppress analyte adsorption and control electroosmotic flow (EOF). In this mixed surfactant system, the nonionic surfactant DDM functions as a surface blocking reagent, whereas the anionic surfactant SDS introduces negative charges to the channe...

The effect of the anionic surfactant sodium dodecyl sulfate (SDS) on Pseudomonas fluorescens biofilms was investigated using flow cell reactors with stainless steel substrata, under turbulent (Re = 5200) and laminar (Re = 2000) flow. Steady-state biofilms were exposed to SDS in single doses (0.5, 1, 3 and 7 mM) and biofilm respiratory activity and mass measured at 0, 3, 7 and 12 h after the SDS...

Objective: In this study, we examined the characteristics of depressien determination using four representatiye selfirating depression scales (Geriatric Depression Scale, GDS; Selfirating Depression Scale, SDS; Center for Epidemiotogic Studies Depressien Scale, CES-D; and Carroll Rating Scale, CRS) applied to Japanese community-dwelling elderly. Methods: Subjects were 563 community-dwelling ind...

The L4 molecular chirality can be amplified to a supramolecular scale by coassembling with SDS. Further incorporation of the CB[8] leads inversion via change from lamellar structure L4/SDS rectangular stacking in L4/SDS/CB[8].

This paper characterizes the complexes formed by a small protein, ubiquitin (UBI), and a negatively charged surfactant, sodium dodecyl sulfate (SDS), using capillary electrophoresis (CE), circular dichroism (CD), and amide hydrogen-deuterium exchange (HDX; as monitored by mass spectroscopy, MS). Capillary electrophoresis of complexes of UBI and SDS, at apparent equilibrium, at concentrations of...

Hydrate-based gas separation is a potential technology for CO 2 recovery and storage, its products can be used fire prevention control in mines. Promoters are often employed to accelerate or moderate hydrate formation. In this study, experiments were performed examine the effects of different concentrations thermodynamic promoter tetrahydrofuran (THF) kinetic sodium dodecyl sulphate (SDS) on fo...

BACKGROUND Models assessing characteristics contributing to response to recombinant human growth hormone (rhGH) response rarely address growth extremes in both years 1 and 2 or examine how children track from year to year. Using National Cooperative Growth Study (NCGS) data, we determined characteristics contributing to responsiveness to rhGH and the pattern of change from years 1 to 2. PATIE...

OBJECTIVE This study was performed to provide psychometric data concerning the Zung Self-Rating Depression Scale (SDS) when administered to schizophrenics. METHODS The subjects were 110 schizophrenic inpatients (50 females and 60 males) who were diagnosed according to the DSM-IV criteria for schizophrenia. Informed consent was obtained from all subjects. RESULTS 1) Cronbach's alpha for the ...

A previous study, using capillary electrophoresis (CE) [J. Am. Chem. Soc. 2008, 130, 17384-17393], reported that six discrete complexes of ubiquitin (UBI) and sodium dodecyl sulfate (SDS) form at different concentrations of SDS along the pathway to unfolding of UBI in solutions of SDS. One complex (which formed between 0.8 and 1.8 mM SDS) consisted of native UBI associated with approximately 11...
