Objective: To compare the effects of polyacrylamide and hydroxypropyl methylcellulose on postoperative intraocular pressure (IOP) elevation. Material and Methods: This prospective study comprised 80 eyes of 72 consecutive patients who underwent cataract surgery and implantation of foldable intraocular lens. Each eye was assigned to either group 1 or group 2. Polyacrylamide was used in group 1 a...

Gastroretentive bimodal drug delivery systems of lamotrigine were developed using immediate release and extended release segments incorporated in a hydroxypropyl methylcellulose capsule and in vitro and in vivo evaluations were conducted. In vivo radiographic studies were carried out for the optimized formulation in healthy human volunteers with replacement of drug polymer complex by barium sul...

The developmental toxicities of seven acrylates were studied in Sprague-Dawley rats after inhalation exposure for 6 h/day, during days 6 to 20 of gestation. The exposure concentrations were: for acrylic acid, 50, 100, 200, or 300 ppm; for methyl acrylate, 25, 50, or 100 ppm; for ethyl acrylate, 25, 50, 100, or 200 ppm; for butyl acrylate, 100, 200, or 300 ppm; for ethylhexyl acrylate, 50, 75, o...

The glucosinolate(GS)-myrosinase system of Brassicaceae, including the model plant Arabidopsis thaliana (L.), comprises a defence which is effective especially against generalist herbivores. Based on their side chain structure GS are grouped into aliphatic, aromatic, and indolyl GS. Indolyl GS are widely distributed among A. thaliana ecotypes and the Brassicaceae family, but the presence of ali...

Solubilisation of six polycyclic aromatic hydrocarbons (PAHs) (acenaphthene, anthracene, fluoranthene, fluorene, phenanthrene and pyrene) by three synthetic cyclodextrins (CDs) (2-hydroxypropyl-β-CD, hydroxypropyl-γ-CD and randomly methylated-β-CD) was investigated in order to select the CD which presents the greatest increase in solubility and better complexation parameters for its use in cont...

The reaction of glyceraldehyde (aldotriose) with hemoglobin A is analogous to the nonenzymic glycosylation of the protein with glucose in that the initial reversible Schiff base adduct (aldimine) of aldotriose undergoes Amadori rearrangement as does that of aldohexose to form the more stable ketoamine adduct. The modification of the alpha-amino group on Val-1(beta) of hemoglobin A as a ketoamin...

Many benzo[b]furan lignans are known to be biologically active in nature. 2-(3'-Methoxy-4'-hydroxy-phenyl)-5-(3-hydroxypropyl)-7-methoxy-benzo[b]furan-3-carbaldehyde (XH-14) is found as a bioactive component isolated from the plant Salvia miltiorrhiza, commonly known as Danshen, which is a traditional Chinese medicine that is used as a cardiovascular medication. This study examined whether 3 di...

An HPMA-based polymeric prodrug of a CXCR4 antagonist, AMD3465 (P-SS-AMD), was developed as a dual-function carrier of therapeutic miRNA. P-SS-AMD was synthesized by a copolymerization of HPMA with a methacrylamide monomer in which the AMD3465 was attached via a self-immolative disulfide linker. P-SS-AMD showed effective release of the parent AMD3465 drug following treatment with intracellular ...

Although hydroxypropyl methylcellulose (HPMC) has been proposed as renewable substitute for traditional plastic, its barrier and active properties need to be improved. Thus, the combination of an organic residue such...
