Guide to optrel filters This information is intended to provide an overview of the relevant factors that will help in the selection of a suitable fil- ter. If you lack the necessary information and/or are not sure about your choice, consult a professional first. Only with the right choice you can protect yourself from the health risks caused by pollutants in the ambient air. 1. information you need for a correct choose: • Pollutants in the ambient air • Concentration(s) of the pollutant(s) • Aggregate state(s) of the pollutant(s) (gaseous, solid, as a mixture) • Can the pollutants be detected without aids? (e.g. odor or taste) • The valid limit values e.g. AGW, OEL, ... • Oxygen content of the ambient air. There are locally different minimum concentrations apply (Germany at least 17 vol. %) • Should respiratory protection be combined with other be combined? (head, eye or hearing protection) 3. selection of the suitable filter device With the information from chapter 2, the necessary protection factor can be determined.

Effect of Rutin on Gentamicin-Induced Ototoxicity in Rats: a Biochemical and Histopathological Examination
ORIGINAL ARTICLE ENT UPDATES 11(1):8-13 DOI: 10.5152/entupdates.2021.887158 Effect of Rutin on Gentamicin-Induced Ototoxicity in Rats: A Biochemical and Histopathological Examination Abstract Objective: Gentamicin is a broad-spectrum aminoglycoside antibiotic administered parenterally for moderate to severe gram-negative infections. Ototoxicity is an im- portant side effect that limits gentamicin use. The aim of this study is to investigate the effect of rutin on gentamicin-induced ototoxicity in rats biochemically and histo- pathologically. Methods: Distilled water was administered by oral gavage to healthy controls (HG) and cobalt administered group (GC). 50 mg/kg rutin was administered by oral gavage to rutin + gentamicin (RGG) group. After one hour, 100 mg/kg gentamicin was injected intraperitoneally (i.p) to the RGG and GC animal groups. This procedure was repeated once a day for 14 days. Results: Malondialdehyde (MDA), nuclear factor-κB(NF-κB), tumor necrosis factor alpha (TNF-α) and interleukin-1 beta(IL-1β) levels in the cochlear nerve tissue of gen- tamicin-treated animals were significantly higher compared to healthy controls and rutin + gentamicin treated rats. On the other hand, the amount of total Glutathione (tGSH) was significantly lower compared to the control and rutin group. Histopatho- logical examination revealed degenerated myelinated nerve fibers in the gentamicin group and Schwann cell nuclei were generally not seen. There was a high accumula- tion of collagen fiber in the tissue and dilated blood capillaries. In the rutin group, my- elinated nerve fibers mostly exhibited normal morphology, Schwann cell nuclei were İsmail Salcan1 evident and the vessels were normal. -

A Review on Electrochemical Properties of Choline Chloride Based Eutectic Solvent in Mineral Processing

August 2017 Vol. 21 (5) 991-998 www.ajol.info and All rights reserved www.bioline.org.br/ja A Review on Electrochemical Properties of Choline Chloride Based Eutectic Solvent in Mineral Processing *1OBETEN, ME; UGI, BU; ALOBI, NO Department of Chemical Sciences, Cross River University of Technology, P. M. B. 1123 Calabar - Cross River State, Nigeria. ABSTRACT: Our review highlights the most recent developments in ionic liquid (IL) chemistry where the “well-known” description of IL properties sometimes proves to be inaccurate. However, in the authors’ opinion, all these new research developments concerning ionic liquid properties serve to update knowledge on the typical physical and chemical properties of ILs, which is significant to both theoretical research and industrial applications. Therefore, rather than attempting to give a comprehensive overview of ionic liquid chemistry, the paper presents an opportunity to understand deep eutectic solvents (DES) through a more complete and accurate view . © JASEM https://dx.doi.org/10.4314/jasem.v21i5.29 Keywords : Eutectic; Solvents; Electrochemistry; Ionic Liquids; purification; Ethylene glycol. Since environmental pollution caused by chemical mixed with different hydrogen bond donors (HBDs) and energy industries has increased for several such as urea, ethylene glycol, acetamide or decades, there is high expectation from scientists and hexanediol (type IV DES). engineers to design sustainable chemical processes, to generate less harmful materials and more Owing to its low cost, biodegradability and low environmentally friendly sources of energy toxicity, ChCl was widely used as an organic salt to production.
