Memória de atos regulatórios na comunicação na UFRGS: uma proposta analítica

Referendando-se teoricamente em Hall (1997), este artigo propõe uma reflexão sobre os atos regulatórios relativos ao setor de comunicação da Universidade Federal do Rio Grande do Sul (UFRGS), com ênfase na memória da Assessoria de Imprensa. Através de pesquisa documental, examinamos as atribuições e os objetivos pelos quais a Universidade e o setor foram regulados, detendo-nos nos períodos ditatoriais e sob o neoliberalismo, concluindo que se nestes a tendência é a desregulação, as ditaduras se caracterizam pela regulação da cultura. Finalmente, discutimos, nos dias de hoje, como a Assessoria de Imprensa vem sistematizando atividades e criando normas e políticas para sua atuação.

The objective of this study shows the probable contribution of immune changes to neurobiological events in autism. The participants were 17 children, between 3 to 9 years old, classified as ASD according to Diagnostic and Statistical Manual of Mental Disorders 4th Edition, (DMS-IV). The severity of the disease was measured by the Childhood Autism Rating Scale (CARS) and the heterogeneity of functioning of ASD children was also considered. Each observation was analyzed between the ASD (groups- subgroups) and controls. Cytokine profile was assessed in plasma samples of ASD patients and age-matched typically developing (AMTD). Plasma cytokine detection was carried out using a sandwich ELISA kit following the manufacturer´s instruction (Quantikine ELISA). Statistical analysis reaches significant increases in plasma levels of IL-1β, IL-6, IL-17, IL-12p40 and IL-12p70 cytokines in autistic group compared with AMTD (p<0.05). Significant differences between clinical variables and cytokines were also observed in ASD clinical subgroups. Increased IL-4 cytokine level was associated with paroxistic activity in the EEG, focused to a particular brain region, as well as some changes in cytokines levels were observed regarding the EEG changes. The present result drives novel association between clinical and neurobiological markers in ASD and confirms the hypothesis on relevant contact points between clinical and neuroinflammatory events in autism.

A sintaxe espacial como instrumento para a construção de cenários urbanos: o caso da Lapa (RJ, Brasil)

This paper explores the use of scenarios building as a resource for structuring the urban project process in a complex and open perspective in a design approach. It is based on a case study of the Lapa neighborhood in the city of Rio de Janeiro, in Brazil and is the product of an ongoing research theme on public policies and territory at the Urban and Regional Graduate Program (PROPUR) of Federal University of Rio Grande do Sul (UFRGS). The method proposed includes the problematization of the project by scenarios vis-a-vis the space syntax analyses in order to establish the common points, as well as to generate data about accessibility and spatial integration. The intersection of these methodological approaches point out to the possibilities of syntax theory used toward the structuring of project process based on scenarios building by design. In doing so, we consider the following criteria: the local-global relationship; social integration; strategic dialogues; and co-responsibility on decision-making and new structures of governance. The main interest is to bring together for examination at the level of ideas distinct scenarios, as mental constructo drawn from social processes in order to highlight their differences and uncover distinct courses of action as guidelines for the project. The space syntax theory allows to link scenarios building by design from an imagery plan to a topological dimension of urban space. Keywords: territory by design, urban project by scenarios, space syntax, Brazilian cities.

Hipospadia perineal em um cão: relato de caso

A hipospadia é uma anomalia congênita da genitália externa, na qual a uretra peniana termina ventral e caudalmente à sua abertura normal. Pode ser classificada, com base na localização da abertura uretral, como glandular, peniana, escrotal, perineal e anal. O objetivo deste trabalho é relatar um caso raro de hipospadia perineal, em que são abordados seus aspectos clínicos e terapêuticos, em um cão macho, sem raça definida, com seis meses de idade. Um canino com histórico de suspeita de hermafroditismo e presença de um orifício, logo abaixo do ânus, pelo qual urinava foi atendido no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul (UFRGS). Durante o exame físico, foi observado o meato uretral localizado ventralmente ao ânus, além de alterações no prepúcio, pênis e escroto. Foram realizados exames de triagem, tais como: hemograma completo, urinálise, ecografia abdominal e uretrocistografia. O cão foi encaminhado para a cirurgia, quando foi submetido à amputação peniana e prepucial total e também à orquiectomia. O canino recebeu antibioticoterapia, analgésicos, anti-inflamatório e limpezas diárias dos pontos e da região perineal e apresentou excelente recuperação pós-operatória. Após 30 dias da cirurgia, o paciente retornou ao hospital, e foi verificada completa cicatrização da ferida cirúrgica, sem sinais de infecção urinária e inflamação ou assaduras na região perineal. A hipospadia perineal é um caso raro de anomalia uretral congênita, ainda pouco documentada em medicina veterinária. O procedimento cirúrgico realizado demonstrou ser importante, uma vez que removeu toda a genitália externa defeituosa, onde, futuramente, poderiam desenvolver-se infecções e/ou inflamações. Com isso, minimizou as complicações dessa doença e melhorou a qualidade de vida do paciente.

Israel Roisenberg (1934-2013): a life dedicated to science

Historians of science have continuously searched forthe factors which determine why certain persons achieveproeminence in the area. Of prime importance, of course, istheir biological constitution; only persons with a given de-gree of intelligence can reach success. But there are manyadditional factors which are also important, including workdrive, persistence, as well as appropriate family and aca-demic environments.This combination of factors led to Israel Roisenberg’sbrilliant career, and the main events of his life are listed inTable 1. He was born in Porto Alegre on July 31, 1934,wherehelivedallhislife,exceptforvariedperiodsoftimeinSao Paulo and outside Brazil. After primary and secondaryeducation (the latter in a public school, Colegio Julio deCastilhos), he was approved in the Federal University of RioGrande do Sul (UFRGS) entrance exam for the BiologicalSciencesCareerin1958.Soonhedevelopedaninterestinre-search, and as a consequence I invited him to work as an un-dergraduate student in our laboratory. He graduated in 1961and soon afterwards received a contract as a Biologist atUFRGS. Our Post-Graduate Program was just starting at thetime, but he also immediately enrolled as a Ph.D. student.At the time I had just returned from the US, where Iwas enjoying a Post-Doctorate stay at the Department ofHumanGenetics,SchoolofMedicine,UniversityofMichi-gan in 1957/58, and was starting a research program in thearea which involved not only the population genetics ofAmerindians, but also medical genetics, due to the absenceof specialists, at the time, in this field. Several hemophiliapatients had looked for help in our Genetic Counseling Ser-vice, and therefore I suggested to Israel to work with thiscondition for his Doctoral Thesis.This was the beginning of a distinguished interest incoagulation and hemostatic disorders that lasted for all hislife. To learn the specific coagulation techniques he stayedfor some time at the Butantan Institute in Sao Paulo, underthe guidance of Gastao Rosenfeld, with whom he after-wards developed a strong friendship. The Ph.D. degree wasawarded in 1968, and he was the first student to obtain it inour Program.Newton E. Morton was at the time working in an ex-tensive program of research with northeastern Brazilians,and one of the logical choices was that Israel would go tohis laboratory for a Post-Doctorate stay. This occurred in1968/69, and there he obtained skills in the electronic pro-grams developed by Morton and performed field work inthe Pacific Islands. As a result, they published papers sum-marizingthegenealogicaldataobtainedinthePingelapandMokil attols (no. 5, List of Selected Publications) and theresults of his Ph.D. Thesis (6). They also examined aspectsof the population structure of Central and South AmericanAmerindians (4).Back in Brazil, he organized a highly successfulgroup of research in hemostasis and was actively engagedin undergraduate and graduate teaching. In relation to thelatter, 23 M.Sc. and 7 Ph.D. degrees were obtained underhis guidance from 1974 up to 2005.Along the years he made additional stays in the USA(1977) and Wales (1989), was the Coordinator of our Post-Graduate Program in Genetics and Molecular Biology foran extended period of time (1976-1992), President of theUFRGS Central Administration Post-Graduate SpecialChamber (1991/96), and received national recognition asPresident of the Brazilian Society of Genetics (1974-1976),as Member of the Council, Brazilian Society for the Ad-vancement of Science (SBPC) (1975/79), and was invitedto join the Advisory Committees of the Brazilian NationalCouncil for Research and Development (CNPq) in 1985-1989 and 2000/2001, as well as to the Rio Grande do SulState Foundation for the Development of Science(FAPERGS), from 1998 to 2001.

A Comissão Especial de Investigação Sumária da UFRGS (1964)

A atuação da Comissão Especial de Investigação Sumária, instalada na Universidade Federal do Rio Grande do Sul (UFRGS) em maio de 1964, resultou no expurgo de doze professores daquela instituição. Foi uma das várias ações da chamada “Operação Limpeza”, um amplo processo coercitivo realizado em todo o Brasil nos primeiros meses após o golpe de 1964.

Conventional caries removal and sealed caries in permanent teeth: A microbiological evaluation

ObjectivesThe aim of this study was to compare microbiological infection after conventional carious dentine removal with incomplete carious dentine removal and sealing. MethodsEighty-seven patients (12–50 years of age) under treatment at the Dental Clinics of the Federal University of Rio Grande do Sul (UFRGS), Brazil, participated in the study. The patients presented 90 posterior permanent teeth with primary caries. The lesions were coronal, active, and reached at least the middle third of the dentine. None of the teeth exhibited spontaneous pain, sensitivity to percussion or apical pathology (detected through radiographic exams). Pulp sensibility was confirmed by the cold test. The lesions were divided into 2 experimental groups: complete caries removal (CCR) based on hardness criteria (n=60 lesions) and incomplete caries removal (ICR) and sealing (n=32 lesions). Microbiological samples were obtained from the initial demineralized dentine, after CCR and after ICR-Seal. ResultsThe number of anaerobic and aerobic bacteria, lactobacilli, and mutans streptococci decreased at the end of treatment (p<0.05). Significantly less anaerobic bacteria (p<0.01), aerobic bacteria (p=0.02), and mutans streptococci (p<0.01) growth was observed after ICR-Seal compared to CCR. The difference in lactobacilli was insignificant (p=0.08). The amount of bacteria detected after conventional caries removal was higher than that which remained in sealed caries lesions. ConclusionsThe results suggest it is not necessary to remove all carious dentine before the restoration is placed because over time, sealing of carious dentine results in lower levels of infection than traditional dentine caries removal. Clinical significanceThe results of this study indicate that sealed carious dentine was less infected than the remaining dentine left after conventional caries removal and sealing. Our results support treatment of deep carious lesions in one session with incomplete removal of carious dentine.

Seleção a campo de rizóbios nativos para cornichão

O cornichão (Lotus corniculatus L.) tem sido apontado como uma das forrageiras mais promissoras para o uso no Rio Grande do Sul. No entanto, pouco se conhece a respeito da interação dessas plantas com os rizóbios nativos em condições de campo. Este estudo visou a avaliar a eficiência das interações entre rizóbios e plantas de Lotus corniculatus cv. 'São Gabriel' em condições de campo. O experimento foi conduzido na Estação Experimental Agronômica da UFRGS com delineamento de blocos ao acaso com quatro repetições. Os tratamentos estudados foram: dois controles sem inoculação (um com a adição de 80kg ha-1 de nitrogênio na forma de uréia e outro sem a adição de nitrogênio); inoculação com rizóbios: estirpes SEMIA 816, recomendada no Brasil, U510, recomendada no Uruguai, U512, em estudo no Uruguai, e quatro isolados de rizóbios nativos (UFRGS Lc322, UFRGS Lc349, UFRGS Lc269 e Iso 7). O isolado UFRGS Lc322 e a estirpe U510 são mais eficientes do que a estirpe SEMIA 816, recomendada para cornichão no país. Além disso, a produção de forragem das plantas inoculadas com o isolado UFRGS Lc322 e a estirpe U510 superou a obtida com a adição de 80kg ha-1 de nitrogênio.

O tema da dualidade onda-partícula na educação profissional em radiologia médica a partir da simulação do interferômetro de Mach-Zehnder

Neste artigo apresenta-se a aplicação de uma proposta de introdução de tópicos de física moderna a estudantes de um curso técnico na área da saúde e a avaliação de um software tipo bancada virtual que simula o interferômetro de Mach-Zehnder. A teoria sociointeracionista de Vygotsky e a ênfase curricular Ciência-Tecnologia-Sociedade foram tomados como referenciais. No âmbito do Mestrado Profissional em Ensino de Física da Universidade Federal do Rio Grande do Sul (UFRGS), fez-se a aplicação de uma proposta de inovar a abordagem de tópicos como dualidade onda-partícula e fenômenos de interação da radiação com a matéria a uma turma de 32 alunos de um curso técnico em Radiologia Médica. A partir das observações e constatações em aula, pode-se dizer que o software possui todas as potencialidades que o tornam uma ferramenta muito útil no ensino e na aprendizagem de fundamentos de física quântica, levando os alunos a construírem conhecimentos e estabelecer a correlação destes com outros tópicos abordados durante o curso.

The VARSUL Database

This study introduces the Project that gave origin to one of the most important databases about oral language in Brazil. The Project on Urban Linguistic Variation in the South of Brazil (VARSUL), that started in 1990, initially comprised the three federal universities of the three States of Southern Brazil: Federal University of Santa Catarina (UFSC), Federal University of Paraná (UFPR) and Federal University of Rio Grande do Sul (UFRGS). In 1993, the Project began to also rely on the Pontific Catholic University of Rio Grande do Sul (PUC–RS). The VARSUL Project aims at storing samples of speech realizations by inhabitants of socio-representative urban areas from each of the three states of the South of Brazil, stratified by location, age range, gender and education.

Intoxicação por veneno de sapo em um canino

O sapo do gênero Bufo possui nas suas glândulas paratóides uma secreção mucóide contendo toxinas como bufaginas e Bufotoxinas, que são esteróides cardiogênicos. Os cães podem atacar os sapos, entrando em contato com o veneno por meio das mucosas. Um canino, da raça Bulldog Francês, foi encaminhado ao Setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (UFRGS) para a necropsia com histórico de provável intoxicação por veneno de sapo. Na necropsia o canino apresentava pulmões aumentados de volume, avermelhados e com edema, e rins de coloração vermelho-escura. As alterações microscópicas indicaram congestão, hemorragia e edema pulmonar. Nos rins, no baço e nos linfonodos foi observada congestão. As análises toxicológicas para os venenos de rotina foram negativas. Porém, a investigação do veneno de sapo a partir de cromatografia por camada delgada e gasosa demonstrou resultado positivo, revelando ser esta a causa da morte do canino.

Qualidade de sementes de acessos de melão crioulo (Cucumis melo L.)

O estudo avaliou a qualidade de sementes de seis acessos de melões crioulos (Cucumis melo L.), oriundos de propriedades de agricultores familiares de diferentes regiões do estado do Rio Grande do Sul. Os ensaios experimentais foram realizados no Laboratório de Análise de Sementes do Ministério da Agricultura (LASO/LANAGRO-RS) e no Laboratório de Sementes do Departamento de Plantas Forrageiras e Agrometereologia da Faculdade de Agronomia da UFRGS. As sementes de cada acesso foram avaliadas quanto a coloração e dimensão e submetidas às seguintes determinações: peso de mil sementes, germinação, primeira contagem de germinação, índice de velocidade de germinação, peso seco das plântulas, tamanho das plântulas e envelhecimento acelerado e sanidade. Todos os acessos apresentaram mais de 80% de germinação, independente das condições de manejo pós-colheita e armazenamento. As sementes dos acessos de melões tradicionais apresentaram variações significativas na coloração e dimensões. Os testes sanitários não indicaram a presença de vírus ou bactérias nos acessos, embora tenha sido observada a presença dos fungos Phoma sp., Cladosporium sp. e Fusarium sp.
