Functional Polysaccharide Composite Nanoparticles from Cellulose Acetate and Potential Applications

Abstract: An in situ technique for preparing composite nanoparticles from hydrophobic cellulose acetate and hydrophilic polysaccharides using nanoprecipitation is presented. This technique allows the nanoparticles’ surface properties to be tuned very specifically. Spherical, narrow-size-distributed composite nanoparticles of different size, charge, functionality, and increased stability can be generated by using hydroxyethyl cellulose, carboxymethyl cellulose, low molecular weight chitosan, and amino cellulose. The influence of the pH and hydrophilic polysaccharide content in the particle formation is shown. The pH- and ionic strength- effective zeta-potential functions are evidence of the presence of functional polysaccharides at the nanoparticle surface. The in situ technique is compared with the adsorption of hydrophilic polysaccharides onto cellulose acetate nanoparticles in two steps. The great potential of in situ prepared composite nanoparticles in the pharmaceutical industry and bio- or food technology, as carriers of hydrophobic substances in aqueous media and for specific surface modifications, e.g., to selectively introduce strong antimicrobial properties, is illustrated.

Sol-gel based optical sensor for dissolved ammonia

Abstract: Ormosils were prepared in different ratios of tetramethoxysilane and organically modified sol-gel precursors of type R′Si(OR) 3 and R′ 2 Si(OR) 2 . The pH indicator aminofluorescein was incorporated into various ormosils and the resulting materials were tested for their relative response to pH and dissolved ammonia at constant pH. R′ 2 Si(OR) 2 -based layers were recognized as the most promising materials because of their high permeability to ammonia, impermeability to ions (protons), long operational lifetime and good photostability.

Observation of an enhancement in e+e-→Υ(1S) πn+n-→Υ(2S)n+n- and (3S)n+n- production near s = 10.89 GeV

Abstract: We measure the production cross sections for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\Upsilon}(1S){\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, $\ensuremath{\Upsilon}(2S){\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, and $\ensuremath{\Upsilon}(3S){\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ as a function of $\sqrt{s}$ between 10.83 GeV and 11.02 GeV. The data consist of $8.1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the Belle detector at the KEKB ${e}^{+}{e}^{\ensuremath{-}}$ collider. We observe enhanced production in all three final states that does not agree well with the conventional $\ensuremath{\Upsilon}(10860)$ line shape. A fit using a Breit-Wigner resonance shape yields a peak mass of $[10\text{ }{888.4}_{\ensuremath{-}2.6}^{+2.7}(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}1.2(\mathrm{syst})]\text{ }\text{ }\mathrm{MeV}/{c}^{2}$ and a width of $[{30.7}_{\ensuremath{-}7.0}^{+8.3}(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}3.1(\mathrm{syst})]\text{ }\text{ }\mathrm{MeV}/{c}^{2}$.

Treatment of vulvovaginal candidiasis: a review of the literature.

Abstract: Vulvovaginal candidiasis (VVC) affects around three-quarters of all women during their reproductive age, although the exact incidence of VVC is difficult to determine because many patients are self-treated. The infections are divided into complicated and uncomplicated. Uncomplicated VVC is most effectively treated with local azoles. Oral treatment with a single dose of fluconazole is also effective for treating uncomplicated VVC. Treatment of complicated VVC is prolonged and most commonly consists of multiple doses of oral fluconazole or at least 1 week of local azoles. The role of probiotics in treating VVC is still disputed. This article presents a review of the literature on the various treatment options for VVC. Treatment for the most common pathogens that cause complicated VVC is also discussed.
