We report the case of a manicurist who developed an allergic skin reaction to acrylates, manifested by bullous lesions on fingertips and eczema of the hands and ears. Patch tests showed positive reactions to 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, ethyleneglycol dimethacrylate, triethyleneglycol dimethacrylate, 1,6-hexandiol diacrylate, 2-hydroxyethyl acrylate and triethylene...
A bisthienylethene with hitherto unprecedented facial chirality imposed by a triethyleneglycol bridge on a thiophene ring was synthesized and its photochromic ring closure was shown to occur with 100% diastereoselectivity upon UV-light irradiation.
the carrier facilitated transport of the lithium ions by a series of non-cyclic synthetic ionophores
the carrier facilitated transport of lithium picrate was studied using a series of non-cyclic polyethers containing different end groups and chain lengths through bulk liquid membrane (blm) and supported liquid membrane (slm) systems. the various membrane supports used are viz. ptfe, cellulose nitrate, and dialysis membrane and onion membrane. the amount of li+ transported depends upon the stru...
A library of 24 new mannose-centered tetragalactoclusters with four different linkers (di- and triethyleneglycol with phosphodiester or phosphorothioate linkages) and six different aromatic aglycons (O-phenyl, S-phenyl, O-benzyl, S-benzyl, O-biphenyl and O-naphthyl) was synthesized. Their interactions with LecA were evaluated on a DNA Directed Immobilization (DDI) based glycocluster array allow...
The synthesis and the optical properties of a family new fluorenyl phthalocyanines substituted with water-solubilizing triethyleneglycol chains is described. These biocompatible molecules exhibit strong one- two-photon absorptions, together fluorescence photosensitization similar to those their lipophilic analogues, thus outperforming unsubstituted zinc phthalocyanine in terms brightness single...
Photopolymerization is an environmentally-friendly, non-destructive, safe and solvent-free method. Moreover it guarantees low energy consumption. Therefore the photopolymerization used in many scientific disciplines, including dentistry for production photocurable dental materials. In this work, new photoinitiating systems based on camphoroquinone (CQ) iodonium salts with tosyl anion initiation...
Components of resin materials may damage DNA, leading to genetic alterations in mammalian cells. Here, monomers were analyzed for the induction of chromosomal aberrations indicated by micronuclei induced in V79 cells. A dose-related increase in the numbers of micronuclei was observed with triethyleneglycol dimethacrylate (TEGDMA), 2-hydroxyethyl methacrylate (HEMA), and glycidyl methacrylate (G...
The formation of mixed self-assembled monolayers (SAMs) from novel biotinylated alkylthiols (BAT) and diluent triethyleneglycol (TEG) alkylthiols on gold has been accomplished using aqueous solvents. We compare the effects of aqueous and ethanolic solvents on the binding performance of mixed SAMs and the integrity of monolayers formed. We use cyclic voltammetry (CV) and fluorescence microscopy ...
