a study was made on the interaction between histon h1 and sodium n-dodecyl sulphate (sds) in the presence of sodium arsenate inside a phosphate buffer of ph 6.4, using spectroscopy and equilibrium dialysis at 27 °c. the binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the wyman binding potential. the binding data hs been analysed in terms of hi...

In study, spherical Silver nanoparticles (SNPs) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. In this experimental work, SNPs are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of SNPs have been observed. Further anti...

Polymer composites are among the most rapidly growing research fields in material science. Polymer composites are adding a great deal of material that is more durable and useful as compared to the conventional material. Properties of composite materials greatly depend on the nature, proportion and compatibility of the components of the composite materials. In this paper we have conducted an ana...

Aim: to prospectively evaluate degree of pain during transrectal ultrasound-guided prostate biopsy after receiving analgesics treatment of oral morphine sulphate compared to suppository sodium diclofenac. Methods: the study group comprised 60 consecutive men subjects (median age 67.8 years) undergoing transrectal prostate biopsy. They were randomized into two groups; group 1 received oral analg...

Proteoglycans extracted from separated specimens of healthy human gingival epithelium and from connective tissue have been purified. The epithelial proteoglycans fractionated as a single included peak on Sepharose 4B-CL and contained heparan sulphate and dermatan sulphate glycosaminoglycans. The connective-tissue proteoglycans separated into three major populations on Sepharose 4B-CL, one of wh...

1. Strontium absorption was studied in vivo with loops of ileum in rachitic chicks and found to be increased by vitamin D(3), bile salts and sodium lauryl sulphate. 2. Bile salts and sodium lauryl sulphate rendered strontium soluble in butanol-benzene (1:1, v/v). 3. Bile was not concerned in the absorption of iron in rats from its water-soluble form, ferrous sulphate. 4. Ligation of the bile du...
