This study is to prepare chitosan beads modified with sodium dodecyl sulfate (SDS) effectively remove Cr(III) from an aqueous solution. The characterizations of SDS-chitosan by scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), Fourier transform-infrared (FT-IR) and photoelectron (XPS) proved the successful synthesis adsorbent. adsorption on SDS material was investigat...

Pulsed-field-gradient nuclear magnetic resonance (PFG-NMR) is used to obtain 6 the true hydrodynamic size of complexes of peptides with sodium dodecyl sulfate SDS 7 micelles. The peptide used in this study is a 19-residue antimicrobial peptide, GAD-2. Two 8 smaller dipeptides, alanine-glycine (Ala-Gly) and tyrosine-leucine (Tyr-Leu), are used for 9 comparison. We use PFG-NMR to simultaneously m...

BACKGROUND Responsiveness to GH treatment can be estimated by both growth and ∆IGF-I. The primary aim of the present study was to investigate if mimicking the physiological increase during puberty in GH secretion, by using a higher GH dose could lead to pubertal IGFs in short children with low GH secretion. The secondary aim was to explore the relationship between IGF-I, IGFBP-3 and the IGF-I/I...

Calcification of bioprosthetic heart valves fabricated from glutaraldehyde pretreated bovine pericardium or porcine aortic valves (PAV) is a frequent cause of the failure of these devices. Of all strategies considered thus far, only detergent preincubations using compounds such as sodium dodecyl sulfate (SDS) inhibited PAV bioprosthetic mineralization in circulatory sheep bioprosthetic valve re...
