Sodium dodecyl sulfate (SDS)-poly(propylene oxide) methacrylate (PPOMA) (of molecular weight M(w) = 434 g x mol(-1)) mixtures have been studied using conductimetry, static light scattering, fluorescence spectroscopy, and 1H NMR. It has been shown that SDS and PPOMA form mixed micelles, and SDS and PPOMA aggregation numbers, N(ag SDS) and N(ag PPOMA), have been determined. Total aggregation numb...

PURPOSE There are inconsistencies in the results reported in a small number of previous studies into growth hormone (GH) treatment in Korean children with idiopathic short stature (ISS) and idiopathic growth hormone deficiency (IGHD). Thus, the authors retrospectively compared the effects of GH in ISS and IGHD. METHODS From the medical records of 26 ISS and 30 IGHD children, auxological and b...

Forest biomass measurement or estimation is critical for forest monitoring at the stand scale, but errors among different estimations in investigation are unclear. Thus, Pinus densata natural Shangri-La City, southwestern China, was selected as research object to investigate of 84 plots and 100 samples P. densata. The calculated using five methods: growth with age (SBA), stem combined expansion...

OBJECTIVES To answer the questions: how does body mass index (BMI) correlate to five overweight related anthropometric variables during different ages in childhood, and which anthropometric variables contribute most to variation in BMI during childhood? METHODS Data on BMI, height (H), sitting height (SH), waist circumference (WC), waist to height ratio (WHtR), waist to sitting height ratio (...

In addition to variation in terms of single nucleotide polymorphisms (SNPs), whole regions ranging from several kilobases up to a megabase in length differ in copy number among individuals. These differences are referred to as Copy Number Variants (CNVs) and extensive mapping of these is underway. Recent studies have highlighted their great prevalence in the human genome. Segmental Duplications...

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...

Metal–aluminum layered double hydroxides (LDHs) intercalated with bis(2-ethylhexyl)sulfosuccinate (EHS) and dodecyl sulfate (SDS) anions, formulated as EHS-MgAl-LDH 1, SDS-MgAl-LDH 2, EHS-CaAl-LDH 3, SDS-CaAl-LDH 4, were synthesized using the co-precipitation method. The compounds characterized Fourier transform infrared spectroscopy, x-ray diffraction, transmission electron microscopy, scannin...
