Potassium tribromide wrapped around polyethylene glycol ({K+PEG400}Br3-) was easily prepared by two step reaction of PEG400 with KBr followed by the addition of molecular bromine to give PEG embedded potassium tribromide as a dark viscous oil. The synthesized material was found to be an efficient, cost effective, environmentally benign and recyclable catalyst for the library synthesis of nitrog...

The sputtering of Au targets onto castor oil generates stable spherical gold nanoparticles (AuNPs) of 2.4 to 3.8 nm. The AuNP size increases with the discharge voltage and the mechanism of nucleation and growth are related to the energy of the atoms/clusters ejected from the target.

Castor (Ricinus communis L, Euphorbiaceous) is needed in the United States to supply caster oil for the hundred of products using this versatile chemurgical raw material. 40-45 thousand tons of castor oil and derivatives are imported each year. Ricinus communis is a common medicinal plant in Ayurveda and is used several part of country for various medicinal properties like the oil of leaf and r...

BACKGROUND: Constipation is one of the common problems in childhood and consists of 3% of referrals to pediatricians and 25% of pediatric gastroenterologists. Aperients are common alternatives for treating chronic constipation. The present study aimed to compare the efficacy of three laxatives [polyethylene glycol (PEG), magnesium hydroxide, and lactulose]. METHODS: In this randomized clinical ...

BACKGROUND Constipation is a common clinical problem. Lactulose and Polyethylene Glycol (PEG) are both commonly used osmotic laxatives that have been shown to be effective and safe treatments for chronic constipation. However, there is no definitive data as to which provides the best treatment. OBJECTIVES To identify and review all relevant data in order to determine whether Lactulose or Poly...

BACKGROUND Several studies with erythropoiesis-stimulating agents claim that maintenance therapy of renal anaemia may be possible at extended dosing intervals; however, few studies were randomized, results varied, and comparisons between agents were absent. We report results of a multi-national, randomized, prospective trial comparing haemoglobin maintenance with methoxy polyethylene glycol-epo...

Castor bean is an important oil-producing plant in the Euphorbiaceae family. Its high-quality oil contains up to 90% of the unusual fatty acid ricinoleate, which has many industrial and medical applications. Castor bean seeds also contain ricin, a highly toxic Type 2 ribosome-inactivating protein, which has gained relevance in recent years due to biosafety concerns. In order to gain knowledge o...

In this study, a nano-Ca(OH)2/Fe3O4 catalyst was used to produce biodiesel from a 1:1 mixed jatropha-castor oil. By loading Ca(OH)2 onto Fe3O4 nanoparticles, it increased the specific surface area by almost 40%, which improved the catalytic activity as it provided a larger area for the reactants to interact. The main purpose of mixing jatropha oil with castor oil was to lower the viscosity of t...

Microemulsions are an intriguing method for delivering poorly soluble drugs, protecting labile controlling drug release, and increasing bioavailability. They can be given topically, orally, or intravenously, use polyethylene glycol (PEG-400) as a co-surfactant to improve the solubility stability of biological classification system (BCS) class II drugs. The goal this research is develop test oil...
