Article history: Received on: 26/07/2015 Revised on: 15/08/2015 Accepted on: 09/09/2015 Available online: 27/09/2015 Objective To evaluate the effect of Polyethylene glycol and β-cyclodextrin on the solubility and dissolution of silymarin, a poorly water soluble herbal drug. Methodology Effects of beta cyclodextrins and Polyethylene glycol on solubility of silymarin were evaluated by phase solu...

The water relations of pepper plants (Capsicum frutescens L.) under conditions conducive to guttation were studied to evaluate the control of plant water stress with polyethylene glycols. The addition of polyethylene glycol 6000 to the nutrient solution resulted in water relations similar to those expected in soil at the same water potentials. Specifically, xylem pressure potential in the root ...

The use of polyethylene glycol 4000 as a non-absorbable, continuously fed faecal marker is described. The intestinal handling and transit of polyethylene glycol is compared with that of chromium sesquioxide and barium sulphate. Polyethylene glycol is an acceptable non-absorbable faecal marker for calcium, phosphorus, and fatty acids, and has several features which commend its use in preference ...

Linear alkyl ethoxylates (polyethylene glycol alkyl ethers) were fermented completely to methane and CO2 in enrichment cultures inoculated with anoxic sewage sludge. Long-chain fatty acids were released as intermediates. No degradation was found with polypropylene glycol and polypropylene glycol-containing surfactants. Two types of primary ethoxylate-degrading bacteria were isolated and charact...

background : staphylococcus aureus strains exhibiting multiple antibiotic resistances are isolated from most communities and hospital infections. treatment of patients with these infections has been difficult. the aim of this study was to detect and extract, the egg yolk immunoglobulin y as a potential source of anti- s. aureus antibody. methods : specific igy was produced by immunizing hens wi...

abstract in order to study the effect of using somaclonal variation on production of resistant lines to water deficit conditions on carrot (daucus carota l.), an experiment was carried out in department of biotechnology of all russian research institute of vegetable crops (raas) in 2008-2009. coated seeds of four carrot cultivars which are cultivated in iran including, monarch, nantes improved,...

objective: due to recent advances in nanotechnology it is now possible to accumulate high atomic-number nanomaterial such as gold nanoparticles (gnps) in cancerous cells and take advantage of their absorbed dose enhancement property as radiosensitizing agents. this study aimed to investigate the absorbed dose enhancement factor due to the presence of pegylated gnps under the irradiation of an m...

pigeonpea (cajanus cajan (l) millsp.) is a drought tolerant legume widely grown in the arid and semi-arid tropics of the world which possesses a deep and extensive root system that succors a number of important physiological and metabolic functions to cope with drought. application of available functional genomics approaches to improve productivity under water deficit requires a better understa...

An efficient and green procedure for the synthesis of 2, 4, 6-triaryl-1H-imidazole in polyethylene glycol under microwave irradiation in excellent yield has been developed. Polyethylene glycol is non toxic, reusable, inexpensive and easily available.
