atom transfer radical polymerization (atrp) of styrene was carried out at 105°c and a monte carlo simulation was employed to model the system. the variations of monomer conversion, the initiator concentration, average molecular weight, and molecular weight distribution were evaluated as the reaction proceeded. according to the results obtained, for similar reaction time, monomer conversion is h...

Resveratrol is a nonflavonoid polyphenolic compound which has a broad range of desirable biological actions which include antioxidant, anti-inflammatory, antidiabetic, cardioprotective, and antitumor activities. However, there is concern that the bioavailability of resveratrol may limit some of its clinical utility. So, the aim of this study was to enhance the dissolution rate and oral hypoglyc...

Introduction The rate of lipolysis of dietary fat depends critically on emulsion particle size, which influences fat absorption and metabolism. In order to study the factors affecting fat emulsification within the gastric lumen it is necessary to measure the degree of emulsification in vivo. The measurement of emulsification is also important in the food industry and in other areas. NMR has bee...

The anodic substitution reaction proceeded smoothly without affecting the oxidation of the nucleophile in a one-step electrochemical operation using acoustic emulsification.

Thiomers are the polymers modified for the mucoadhesive properties and other additive properties by incorporating thiol moieties in the backbone of the unmodified polymeric chain by exchange reactions or simple oxidation reactions. Drug that are less soluble and permeable can be complexed with thiomers for their increased absorption through the mucosal membranes by increase in contact time and ...

The aim of the research work was to chemically modify guargum (GG) as a pH sensitive co-polymer and formulating intestinal targeting ESO nanoparticles (NPs) using the synthesized co-polymer. Poly acrylamide-grafted-guar gum (PAAm-g-GG) co-polymer was synthesized by free radical polymerization. Chemical modification of PAAm-g-GG by alkaline hydrolysis results in formation of a pH-sensitive co-po...
