In this work we present the fabrication of yttrium iron garnet (YIG) films with low magnetic damping on silicon (100) substrate. We show in addition that the sol-gel method is a technique that allows the obtaining of YIG films with good quality. The study by X-ray diffraction (DRX) showed characteristic reflections of the cubic YIG phase as well as a very small reflection typical of the orthorhombic phase. The surface of the film was investigated by scanning electron microscopy (SEM) and showed the formation of very small regular pores. The ferromagnetic resonance measurement shows a good result with a low linewidth value of 53 Oe. Our result here is the lowest value found in the literature for YIG film on silicon substrate. Our result is very important for spintronic experiments because these films obtained by sol-gel are thicker than the same films fabricated by the sputtering and other method. © 2015 Elsevier B.V.

In order to draw evidence-based recommendations concerning the management of autoimmune diseases of the liver, the Brazilian Society of Hepatology has sponsored a single-topic meeting in October 18th, 2014 at São Paulo. An organizing committee comprised of seven investigators was previously elected by the Governing Board to organize the scientific agenda as well as to select twenty panelists to make a systematic review of the literature and to present topics related to the diagnosis and treatment of autoimmune hepatitis, primary sclerosing cholangitis, primary biliary cirrhosis and their overlap syndromes. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript organized in topics, followed by the recommendations of the Brazilian Society of Hepatology. © 2015, IBEPEGE - Inst. Bras.

Soft drinks are industrialized unfermented beverages, free of alcohol, carbonated, rich in artificial flavors and sugar. The intense consumption of such beverages can be related to not inheritable diseases such as caries, allergy, cellulite and stretch marks, gastrointestinal disorders, diabetes and cancer. The aim of this study was to evaluate the carcinogenic potential of different concentrations of soft drinks produced in the Uberlândia city, Minas Gerais State, Brazil, by means of Epithelial Tumor Detection Test using Drosophila melanogaster as a model. Third stage larvae descendants of crosses between D. melanogaster virgin females wts/TM3, sb1 and males mwh/mwh were treated with different concentrations (0.83, 1.66 or 3.33 mL/g) of cola, diet cola, orange or lemon soft drinks. The total epithelial tumor rate observed in flies treated with 3.33 mL/g of cola and orange soft drinks was higher than the negative control. The diet cola and lemon caused no significant increase in the overall frequency of epithelial tumors in D. melanogaster. In conclusion, in these experimental conditions, the cola and orange base soft drinks demonstrated carcinogenic potential in somatic cells of D. melanogaster in the concentration of 3.33 mL/g. © 2016, Universidade Federal de Uberlandia.
