Antibiofilm Efficacy of Tea Tree Oil and of Its Main Component Terpinen-4-Ol Against Candida Albicans
ORIGINAL RESEARCH Periodontics Antibiofilm efficacy of tea tree oil and of its main component terpinen-4-ol against Candida albicans Renata Serignoli Abstract: Candida infection is an important cause of morbidity FRANCISCONI(a) and mortality in immunocompromised patients. The increase in its Patricia Milagros Maquera incidence has been associated with resistance to antimicrobial therapy HUACHO(a) and biofilm formation. The aim of this study was to evaluate the Caroline Coradi TONON(a) efficacy of tea tree oil (TTO) and its main component – terpinen-4-ol – Ester Alves Ferreira BORDINI(a) against resistant Candida albicans strains (genotypes A and B) identified by molecular typing and against C. albicans ATCC 90028 and SC 5314 Marília Ferreira CORREIA(a) reference strains in planktonic and biofilm cultures. The minimum Janaína de Cássia Orlandi inhibitory concentration, minimum fungicidal concentration, and SARDI(b) rate of biofilm development were used to evaluate antifungal activity.

(DGEBA) Epoxy Resin with Maleated Depolymerised Natural Rubber
eXPRESS Polymer Letters Vol.2, No.4 (2008) 302–311 Available online at www.expresspolymlett.com DOI: 10.3144/expresspolymlett.2008.36 Modification of (DGEBA) epoxy resin with maleated depolymerised natural rubber K. Dinesh Kumar1,2, B. Kothandaraman1* 1Department of Rubber and Plastics Technology, MIT campus, Anna University, Chennai-6000 44, India 2Current address: Rubber Technology Centre, Indian Institute of Technology, Kharagpur-721302, India Received 30 December 2007; accepted in revised form 13 March 2008 Abstract. In this work, diglycidyl ether of bisphenol A (DEGBA) type epoxy resin has been modified with maleated depolymerised natural rubber (MDPR). MDPR was prepared by grafting maleic anhydride onto depolymerised natural rub- ber. MDPR has been characterized by Fourier transform infrared (FT-IR) spectroscopy and nuclear magnetic resonance spectroscopy. MDPR was blended with epoxy resin at three different ratios (97/3, 98/2 and 99/1), by keeping the epoxy resin component as the major phase and maleated depolymerised natural rubber component as the minor phase. The reac- tion between the two blend components took place between the acid/anhydride group in the MDPR and the epoxide group of the epoxy resin. The proposed reaction schemes were supported by the FT-IR spectrum of the uncured Epoxy/MDPR blends. The neat epoxy resin and Epoxy/MDPR blends were cured by methylene dianiline (DDM) at 100°C for three hours. Thermal, morphological and mechanical properties of the neat epoxy and the blends were investigated. Free volume stud- ies of the cured, neat epoxy and Epoxy/MDPR blends were correlated with the morphological and mechanical properties of the same systems using Positron Annihilation Lifetime Studies. -

Spice Oleoresins
Institute of Medicine Food and Nutrition Board Committee on Food Chemicals Codex Revised Monograph - Spice Oleoresins Please send comments to the Committee on Food Chemicals Codex, National Academy of Sciences, FO 3042, 2101 Constitution Avenue, N.W., Washington, DC 20418 or email them to [email protected]. All comments must be received by December 15, 1996, for consideration for the First Supplement. ____________________________________________________________________________________ May 31, 1996 Spice Oleoresins DESCRIPTION Spice Oleoresins used in foods are derived from spices and contain the total sapid, odorous, and related characterizing principles normally associated with the respective spices. The oleoresins are produced by one of the following processes: (1) by extraction of the spice with any suitable solvent or solvents, in combination or sequence, followed by removal of the solvent or solvents in conformance with applicable residual solvent regulations (see General Requirements below), or (2) by removal of the volatile portion of the spice by distillation, followed by extraction of the nonvolatile portion, which after solvent removal is combined with the total volatile portion. Spice Oleoresins are frequently used in commerce with added suitable food-grade diluents, preservatives, antioxidants, and other substances consistent with good manufacturing practice, as provided for under Added Substances (see General Provisions). When added substances are used, they must be declared on the label in accordance with current U.S. regulations or with the regulations of other countries that recognize the Food Chemicals Codex. The Spice Oleoresins covered by this monograph are Oleoresin Angelica Seed Obtained by the solvent extraction of the dried seed of Angelica archangelica Linnaeus as a dark brown or green liquid. -

Varnishing Than with Any Other Stage of the Painting Process
INFO SHEET 301 UPDATED JULY 2016 VA R NISHING We get more questions about varnishing than with any other stage of the painting process. Varnishing should be an almost mechanical process undertaken to give your painting a protective coating with the surface quality you prefer (gloss, satin, etc.) and possibly an enhancement of colour contrast. But, if you leave it till the last moment and use a varnish you are not used to, you can ruin the work you are trying to protect. Anxiety and disappointment can be avoided easily if you do sample pieces using the same materials as the painting and varnish them, not the painting, until you get the effect you wanted. Water-based varnishes are tricky to apply and not removable if you dislike the effect, so we suggest they should only be used by artists who have already tried the above experiment. CHROMA SOLVENT FINISHING VARNISHES We recommend and prefer our Chroma Solvent Finishing Varnishes, because they can be used on all our Chroma paint brands, Atelier Interactive, Jo Sonja’s or Archival Oils. Application of all these varnishes is by brush (a broad house paint brush), and clean up is with mineral spirits. If applying multiple coats, allow 24 hours drying time between applications. Choose from these finishes: Gloss Solvent Finishing Varnish • Apply as is for a full gloss, usually one coat. To reduce gloss add Invisible Varnish to your taste. Try 2 parts varnish to 1 part Invisible Varnish, up to 1:1 for less sheen. NOTE: The new varnishes have an anti-mould additive which is diluted if you add turpentine, so to maintain the mould protection for tropical conditions dilute with Invisible Varnish instead. -

The land is relatively flat, and the rich soils are ideal for agriculture. The mild climate allowed for longer growing seasons, and a number of wide, slow moving rivers provided both navigation and a food source. Indeed, John Lawson, the British naturalist and explorer, described North Carolina as "a country, whose inhabitants may enjoy a life of the greatest ease and satisfaction, and pass away their hours in solid contentment."
