Khedmat S1, Hashemi A2, Dibaji F3, Kharrazifard MJ4. J Dent (Tehran). 2015 Jan;12(1):25-30.
OBJECTIVES: This study aimed to assess the effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root dentin.
2.Selective turn-off phosphorescent and colorimetric detection of mercury(II) in water by half-lantern platinum(II) complexes.
Sicilia V1, Borja P, Baya M, Casas JM. Dalton Trans. 2015 Apr 21;44(15):6936-43. doi: 10.1039/c5dt00087d.
The platinum(ii) half-lantern dinuclear complexes [{Pt(bzq)(μ-C7H4NS2-κN,S)}2] () and [{Pt(bzq)(μ-C7H4NOS-κN,S)}2] () [bzq = benzo[h]quinolinate, C7H4NS2 = 2-mercaptobenzothiazolate, C7H4NOS = 2-mercaptobenzoxazolate] in solution of DMSO-H2O undergo a dramatic color change from yellowish-orange to purple and turn-off phosphorescence in the presence of a small amount of Hg(2+), being discernible by the naked-eye and by spectroscopic methods. Other metal ions as Ag(+), Li(+), Na(+), K(+), Ca(2+), Mg(2+), Ba(2+), Pb(2+), Cd(2+), Zn(2+) and Tl(+) were tested and, even in a big excess, showed no interference in the selective detection of Hg(2+) in water. Job's plot analysis indicated a 1 : 1 stoichiometry in the complexation mode of Hg(2+) by /. The phosphorescence quenching attributed to the formation of [/ : Hg(2+)] complexes showed binding constants of K = 1.13 × 10(5) M(-1) () and K = 1.99 × 10(4) M(-1) (). The limit of detection has been also evaluated.
3.A Phosphole Oxide Based Fluorescent Dye with Exceptional Resistance to Photobleaching: A Practical Tool for Continuous Imaging in STED Microscopy.
Wang C1, Fukazawa A2, Taki M3, Sato Y1, Higashiyama T4,5, Yamaguchi S6,7. Angew Chem Int Ed Engl. 2015 Dec 7;54(50):15213-7. doi: 10.1002/anie.201507939. Epub 2015 Oct 23.
The development of stimulated emission depletion (STED) microscopy represented a major breakthrough in cellular and molecular biology. However, the intense laser beams required for both excitation and STED usually provoke rapid photobleaching of fluorescent molecular probes, which significantly limits the performance and practical utility of STED microscopy. We herein developed a photoresistant fluorescent dye C-Naphox as a practical tool for STED imaging. With excitation using either a λ=405 or 488 nm laser in protic solvents, C-Naphox exhibited an intense red/orange fluorescence (quantum yield ΦF >0.7) with a large Stokes shift (circa 5900 cm(-1) ). Even after irradiation with a Xe lamp (300 W, λex =460 nm, full width at half maximum (FWHM)=11 nm) for 12 hours, 99.5 % of C-Naphox remained intact. The high photoresistance of C-Naphox allowed repeated STED imaging of HeLa cells. Even after recording 50 STED images, 83 % of the initial fluorescence intensity persisted.
4.Preoperative skin antiseptics for prevention of cardiac implantable electronic device infections: a historical-controlled interventional trial comparing aqueous against alcoholic povidone-iodine solutions.
Da Costa A1, Tulane C2, Dauphinot V3, Terreaux J2, Romeyer-Bouchard C2, Gate-Martinet A2, Levallois M2, Isaaz K2. Europace. 2015 Jul;17(7):1092-8. doi: 10.1093/europace/euu293. Epub 2015 Apr 26.
AIMS: Local skin antiseptic prevention against cardiac implantable electronic device (CIED) infections is not yet fully understood. This monocentre historical-controlled study sought to (i) conduct a prospective observational analysis comparing two antiseptic skin preparations over two similar consecutive periods of time, one conducted over a 1-year period using an aqueous povidone-iodine solution (Group I) and the other over the following with an alcoholic povidone-iodine solution (Group II); (ii) determine the predictive factors of CIED infection.
