Suplementação de colina para poedeiras comerciais Hisex Brown e hisex White. 2. Deposição de gordura hepática e níveis de lipídeos plasmáticos

64 sixty four week-old Hisex Brown and 64 sixty three week-old Hisex White were fed 4 experimental diets containing 500, 1000, 1500 and 2000 mg of choline/kg. the methionine level was 0.253% for all the experimental diets, equivalent to 80% of the National Research Council requirements. Although the liver weight (g) values were significantly higher for the Hisex Brown strain, liver weight (% BW), liver lipid, plasma estradiol, total plama lipids, plasma triglycerides and plasma total cholesterol did not differ significantly between strains. Plasma GOT and plasma HDL-cholesterol were significantly hogher for the Hisex Brown birds. The choline supplementation at the levels of 1500 and 2000 mg/kg determined a significant reduction of the liver lipid deposition. It was found a significant negative correlation between dietetic levels of choline and total plasma lipids (r = -0,287).  64 galinhas da linhagem Hisex Brown e 64 da linhagem Hisex White, apresentando respectivamente, 63 e 64 semanas de idade, foram alimentadas com rações à base de milho e farelo de soja contendo suplementação de 500, 1000, 1500 e 2000 mg de colina por quilo e nível constante de 0,253% de metionina para todas as dietas experimentais, correspondendo a 80% das necessidades estabelecidas pelo National Research Council. Embora as galinhas Hisex Brown tivessem apresentado peso do fígado (g) significativamente maior que as Hisex White, não foram consignadas diferenças entre as linhagens estudadas no relativo à gordura hepática, níveis plasmáticos de estradiol, lipídeos totais, triglicérides e colesterol total. Os valores de TGO e colesterol HDL no plasma, mostraram-se significativamente mãos elevados nas aves da linhagem Hisex Brown. A adição de colina à dieta, em níveis de 1500 e 2000 mg/kg, determinou redução significativa entre os valores de colina suplementar na dieta e dos lipídeos totais no plasma (r = - 0,287)

Conhecimentos sobre prevenção da SIDA entre profissionais e acadêmicos da área de saúde

Este estudo exploratório foi realizado pelas alunas e alunos da Disciplina de Enfermagem nas Doenças Transmissíveis. Foram analisadas as respostas de 52 questionários distribuídos entre acadêmicos de enfermagem, de medicina, médicos, dentistas, enfermeiros e auxiliares de enfermagem que assistem pacientes com SIDA e enfermeiros que não assistem pacientes com SIDA. Estes questionários versaram sobre medidas de prevenção da transmissão sexual, normal de biossegurança, testes diagnósticos, direitos do paciente e do trabalhador e alterações no atendimento aos portadores desta patologia.This work is a exploratory research based on the analysis of the answers to the questionaires of 52 students and health care professionals knowledge about AIDS sexual prevention, biossecurity, diagnosis tests, patients and workers rights and the modifications of nursing and medica/ care to this kind of diseaseTrata se de un estudio exploratório acerca del conocimiento de la prevención de la SIDA, normas de seguridad biológica, pruebas diagnósticas, derechos de /os enfermos y trabajadores con SIDA y de esa mfermedad. Fueron analizados las respuestas de 52 cuestionários de estudientes de enfermería, nédicos, odontólogos, enfermeras y ajudantes de enfermería

Alignment of the CMS muon system with cosmic-ray and beam-halo muons

This is the Pre-print version of the Article. The official published version of the Paper can be accessed from the link below - Copyright @ 2010 IOPThe CMS muon system has been aligned using cosmic-ray muons collected in 2008 and beam-halo muons from the 2008 LHC circulating beam tests. After alignment, the resolution of the most sensitive coordinate is 80 microns for the relative positions of superlayers in the same barrel chamber and 270 microns for the relative positions of endcap chambers in the same ring structure. The resolution on the position of the central barrel chambers relative to the tracker is comprised between two extreme estimates, 200 and 700 microns, provided by two complementary studies. With minor modifications, the alignment procedures can be applied using muons from LHC collisions, leading to additional significant improvements.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR(Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

Precise mapping of the magnetic field in the CMS barrel yoke using cosmic rays

This is the Pre-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2010 IOPThe CMS detector is designed around a large 4 T superconducting solenoid, enclosed in a 12 000-tonne steel return yoke. A detailed map of the magnetic field is required for the accurate simulation and reconstruction of physics events in the CMS detector, not only in the inner tracking region inside the solenoid but also in the large and complex structure of the steel yoke, which is instrumented with muon chambers. Using a large sample of cosmic muon events collected by CMS in 2008, the field in the steel of the barrel yoke has been determined with a precision of 3 to 8% depending on the location.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

Las temáticas abordadas en los 167 capítulos muestran las grandes líneas de investigación que se desarrollan fundamentalmente en nuestro país, pero también en los otros países mencionados arriba, y señalan además las áreas que recién se inician, con poca tradición en nuestro país y que deberían fomentarse. Los trabajos aquí publicados se enmarcan dentro de las siguientes disciplinas y/o campos de investigación: Fonología, Sintaxis, Semántica y Pragmática, Lingüística Cognitiva, Análisis del Discurso, Psicolingüística, Adquisición de la Lengua, Sociolingüística y Dialectología, Didáctica de la lengua, Lingüística Aplicada, Lingüística Computacional, Historia de la Lengua y la Lingüística, Lenguas Aborígenes, Filosofía del Lenguaje, Lexicología y Terminología
