“Conductive polymer particles, polyaniline (PANI)-coated poly(methyl methacrylate-butyl acrylate-acrylic acid) [P(MMA-BA-AA)] nanoparticles, were prepared. The P(MMA-BA-AA)/PANI core-shell complex particles were synthesized with a two-step miniemulsion
polymerization method with P(MMA-BA-AA) as the core and PANI as the shell. The first step was to prepare the P(MMA-BA-AA) latex particles as the core via miniemulsion polymerization and then to prepare the P(MMA-BAAA)/PANI core-shell particles. The aniline monomer was added to the mixture of water and core nanoparticles. The aniline monomer could be attracted near the outer surface of the core particles. The polymerization of aniline was started under the action of ammonium persulfate (APS). The final product was the desired www.selleckchem.com/products/LY294002.html core-shell nanoparticles. The morphology of the selective HDAC inhibitors P(MMA-BA-AA) and P(MMA-BAAA)/PANI particles was characterized with transmission electron microscopy. The core-shell structure of the P(MMA-BA-AA)/PANI composites
was further determined by Fourier transform spectroscopy and ultraviolet-visible measurements. The conductive flakes made from the core-shell latexes were prepared, and the electrical conductivities of the flakes were studied. The highest conductivity of the P(MMA-BA-AA)/PANI pellets was 2.05 S/cm. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 123:

“PURPOSE: To evaluate the technique and outcomes of deep anterior lamellar keratoplasty (DALK) combined with phacoemulsification for corneal opacity with coexisting cataract.
SETTING: Cornea Service, 3-Methyladenine purchase Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India.
DESIGN: Cohort study.
METHODS: Eyes with cataract of varied nucleus grade and with different corneal pathologies were selected. Modified triple procedures were performed in all eyes.
RESULTS: Twenty eyes were evaluated. The corrected distance visual acuity (CDVA) after 3 months was 20/60 or better in 18 eyes. One eye had 20/80 CDVA as a result of perioperative and postoperative complications. One graft became opaque after postoperative infection.
CONCLUSION: Simultaneous DALK with phacoemulsification was feasible in eyes with coexisting corneal and lenticular pathology, and the outcomes were encouraging.”
“Background: While the majority of pathological gamblers are current cigarette smokers (CS), some have quit smoking (former smokers, FS) while others never smoked (never smokers, NS). The reasons for elevated smoking rates in pathological gambling are not known, but gamblers may use nicotine as a putative cognitive enhancer. This study evaluated impulsivity and cognitive flexibility in a sample of pathological gamblers with differing smoking status.
