This article introduced the work of ethylcellulose based polymeric microsphere loaded with nifedipine for reduction in frequency of administration with low solubility in aqueous medium and high rate of absorption in the stomach. The non-aqueous polymeric suspension was put dropwise into an aqueous medium containing polyvinyl alcohol as a surfactant for the synthesis of microsphere by solvent ev...

the resource intensive human activities (such as mining and extraction of mineral oils for betterment of life and modernization of society) have increased environmental pollution several folds. products of mining and petrochemical industries are advantageous for the modern society. but waste generated such as btex from such industries are carcinogenic, toxic and causes adverse effects on enviro...

The oxidation of beta-D-glucose by the enzyme glucose oxidase was studied in aqueous medium, in solutions of surfactants AOT (2-ethylhexylsulfosuccinate, sodium salt) TX-100 (polyethylene glycol p-tert octyl phenyl ether) and in w/o microemulsion medium (water/AOT/decane) at different water/AOT mole ratio (omega), pH, temperature and in presence of additives. The time-dependent activities of th...

Previously, we reported the horseradish peroxidase (HRP) mediated free radical polymerization of methyl methacrylate.1 The reaction medium was restricted to water/water-miscible co-solvent mixtures that solubilize both the monomer and enzyme. This paper describes HRP-mediated acrylamide polymerizations in aqueous medium with and without the addition of surfactants. Also, studies were conducted ...

PURPOSE To determine whether transforming growth factor-beta 2 (TGF-beta 2) in human aqueous humor inhibits the proliferation of lens epithelial cells. METHODS Bovine lens epithelial cells (BLECs) obtained from the central zone of the anterior capsule were cultured in complete medium (F-12 nutrient mixture supplemented with 5% fetal bovine serum). Human aqueous humor was obtained from 11 pati...

Regioselective S-acylation of coenzyme A (CoA) is achieved under aqueous conditions using various aliphatic and aromatic carboxylic acids activated as their methyl acyl phosphate monoesters. Unlike many hydrophobic activating groups, the anionic methyl acyl phosphate mixed anhydride is more compatible with aqueous solvents, making it useful for conducting acylation reactions in an aqueous medium.

Two new tripodal receptors (1–2) have been synthesized and characterized by various spectroscopic techniques. The nano-aggregates of 1 and 2 (N1 and N2) have been prepared by a re-precipitation method in aqueous medium and have shown different photo-physical properties. Nano-aggregates of 1 (N1) can selectively recognize Hg(2+) in aqueous medium in the presence of other metal ions with enhancem...

This present study investigated the potential of Morinda citrifolia leaf aqueous extract to induce osteogenic differentiation and matrix mineralization of human periodontal ligament (hPDL) cells. Human periodontal ligament cells were cultured in complete medium, ascorbic acid with β-glycerophosphate, or Morinda citrifolia leaf aqueous extract. Morinda citrifolia leaf aqueous extract significant...

The effects of vitreous humor and some of its components on the function of rabbit corneal endothelium were investigated and compared to those of artificial and natural aqueous humor. The rate of fluid pumping across the endothelium was measured while that layer was in contact with: (1) complete medium, an artificial aqueous solution; (2) pooled rabbit aqueous humor; (3) filtered and (4) unfilt...
