The molecular weight and hydrodynamic properties of a polypeptide isolated from the lamellar system of Antirrhinum chloroplasts were determined in sodium dodecyl sulphate solution by measurement of sedimentation velocity, diffusion and effective partial specific volume. The polypeptide fraction exhibits a molecular weight of 25000 which agrees with the apparent molecular weight found by polyacr...

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 present work was conducted on the effect of surfactant on the dissolution rate of ibuprofen tablets. The cationic (Cetyl Trimethyl bromide) and anionic (Sodium dodecyl sulphate) surfactant present in the dissolution media have remarkable effect on the dissolution rate of Ibuprofen. Maximum dissolution was obtained in the presence of anionic surfactant (Sodium dodecyl sulphate) at 0.5% conce...

Background & Aim:  The hot water extract of a mixture of Anogeissus leiocarpus and Prosopis africana is widely used in the northern part of Nigeria for the treatment and management of asthma. Since investigations of its pharmacological activities already justify its use, and the need for standardization of herbal medicine and develop appropriate dosage forms has continued to g...

1. Subunit molecular weights of 76000-82000 were obtained for native and alkylated Tamm-Horsfall glycoprotein by gel filtration on Sephadex G-200 in the presence of sodium dodecyl sulphate. 2. A further estimate of the subunit molecular weight of 79 000± 4000 was obtainedby disc gel electrophoresis in sodium dodecyl sulphate. 3. A minimum value of the chemical molecular weight of 79000±6000 was...

Investigations were undertaken to determine the suitability of sucrose and magnesium sulphate solutions and a silica colloidal suspension with centrifugation for extracting Tylenchulus semipenetrans from citrus roots. The efficiency of incubation, sodium hypochlorite, centrifugation, and maceration methods was also compared. Numbers of females recovered by centrifugation with colloidal silica w...

A 40-year-old woman with a history of alopecia areata related to stress or hormonal changes was treated for bilateral primary symptomatic varicose veins (CEAP clinical score C2S) of pelvic origin, using a staged procedure. Her first procedure entailed pelvic vein embolisation of three pelvic veins using 14 coils and including foam sclerotherapy of the tributaries, using 3% sodium tetradecyl sul...

Radiation protection and cytotoxicity effects of different concentrations cerium oxide nanoparticles in aqueous solution combined with sodium dodecyl sulphate Vero cells irradiated 18 MV beams

background: successful therapy of leishmaniasis depends on effective cellular immune response. we evaluated the effectiveness of sodium selenite and zinc sulphate as known immunomodulator materials, in combination with glucantime® in treatment of cutaneous leishmaniasis lesions resulting from leishmania ma­jor in susceptible animal model. methods: thirty three female mice weighing 18-20 g at th...
