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...

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 re1at...

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...

Maltase/glucoamylase from the rat intestinal brush-border membrane was solubilized by homogenization of the intestinal mucosa in buffer containing 0.5% Triton X-100. After removal of the detergent with butan-1-ol, the enzyme was purified by chromatography on Sepharose 4B and DEAE-cellulose. The final specific activity was 70.3 units/mg of protein in six preparations, comparing favourably with t...

of the detergents used (Evans, 1956), although the sharp cut-off in activity evident lends support to the idea that protein denaturation by anionic detergents involves the formation of protein-detergent micelles (Tanford, 1970). The most effective inhibitor of glucuronidase activity was sodium tridecyl sulphate, whereas sodium pentadecyl sulphate exerted the strongest effects on the sulphatase....
