The aim of the study was to evaluate the influence of glucocorticoids on vital parameters of full-term and preterm lambs from birth to 48 hours of life. Four experimental groups were formed: NDG (normal delivery group - lambs vaginally delivered, n=15, average of 146-day gestation); NDEXG (normal delivery with dexamethasone group - lambs vaginally delivered whose mothers received 16mg of dexamethasone at 141 days of gestation, n=8, average of 143-day gestation); PRE (premature lambs born by cesarean section at 138 days of gestation, n=10) and PREDEX (premature lambs born by cesarean section at 138 days gestation, whose mothers received 16mg of dexamethasone two days before, n=9). Heart and respiratory rates had variations during the observation period, with the highest mean values in the groups of normal deliveries (NDG and NDEXG). Rectal temperature decreased in all groups in the first 60 minutes of life, with the lowest mean values in premature lambs (PRE and PREDEX) and the Apgar score was higher in animals delivered at normal gestational time. Preterm lambs had lower vitality and chance of survival, however, lower mortality rate was observed in offspring of ewes that received dexamethasone two days before surgery.

The scope of this article is to evaluate risk and protection factors for the development of 1-year-olds assisted at family health care units. It is a cross-sectional study involving 65 children of approximately 1 year of age and their mothers attended at two family health care units. The development was assessed using a developmental screening test (Denver II). The mothers filled out the SRQ-20 questionnaire to identify common mental disorder (CMD) indicators. After data collection, descriptive and inferential statistical analysis was performed. Global development was at risk in 43.1% of the children evaluated, and the most affected areas were language and fine motor development; 44.6% of mothers had results indicative of CMD when the child was 1 year of age. In bivariate analysis, reported depression, smoking, infections in pregnancy, CMD after birth and working outside the home were significantly associated with the children's development. After full statistical analysis, CMD was revealed as being a risk factor, and working away from home as being a protection factor. In order to increase the chances of success of programs targeted for children at health care units and avoiding the risk of impaired development, it is important to focus on two aspects: children's stimulation and maternal mental health.

Entre as diversas estratégias de investigação dos efeitos de experiências estressantes no início da vida de um rato, pode-se citar a privação do filhote da mãe por 24h, durante o período neonatal. A privação materna (PM) por 24h entre os dias pós-natais (DPN) 3 e 4 resulta em um hiperresponsividade ao estresse na adolescência (20-30 dias de vida), enquanto que essa mesma manipulação entre os DPN 11 e 12 resulta em hiporresponsividade, avaliado na mesma idade. Traumas na infância e/ou adolescência constituem fator de risco para o desenvolvimento de transtorno de estresse póstraumático (TEPT), uma desordem psiquiátrica caracterizada por rememoração persistente do evento traumático, com dificuldade de extinção dessa memória. Sendo assim, o presente projeto avaliou como um estresse nos primeiros dias de vida (privação materna) e um trauma na adolescência (choque intenso inescapável) interagem de forma a promover maior vulnerabilidade para o desenvolvimento de comportamento tipo-TEPT em ratos. As manipulações na infância, ao contrário do esperado, não interagiram com o trauma na infância, e não alteraram a resposta ao condicionamento e à extinção da resposta de medo, avaliadas pelo comportamento de congelamento. Em relação à resposta de ACTH após o estresse na adolescência, os animais submetidos à privação materna não apresentaram pico de secreção deste hormônio, como ocorreu no grupo controle, sugerindo uma alteração da resposta hormonal causada pela experiência adversa na infância. Sendo assim, a privação materna não influenciou as alterações comportamentais nos animais adultos provocadas pelo trauma na adolescência, mas pode ter alterado a resposta de ACTH ao trauma, na adolescência

A síndrome metabólica é um mal que, segundo projeções, poderá no ano de 2010, acometer de 50 a 75 milhões de pessoas somente nos Estados Unidos. Dessa forma, é de grande interesse a implementação de procedimentos mais eficazes para prevenção e tratamento desta doença. Uma vez que existem limitações nas pesquisas com seres humanos, torna-se necessário o desenvolvimento de modelos experimentais apropriados ao estudo desta questão. Na busca de um modelo experimental adequado ao estudo do papel do exercício na prevenção e no tratamento da síndrome metabólica, o presente estudo analisou o perfil metabólico e a capacidade aeróbia de ratos mantidos com dieta rica em frutose, substrato que tem sido associado à síndrome metabólica, na vida intra-uterina e pós-natal. Foram utilizadas ratas adultas (90 dias) da linhagem Wistar, alimentadas durante a prenhez e a lactação com dois tipos de dieta: balanceada (AIN-93G) e rica em frutose (60% de frutose). Durante a amamentação, os filhotes foram distribuídos em ninhadas pequenas (4/mãe) ou adequadas (8/mãe). Após o desmame, manteve-se as mesmas dietas até os 90 dias, quando foram analisados: tolerância à glicose (teste de tolerância à glicose), sensibilidade periférica à insulina (teste de tolerância à insulina); capacidade aeróbia (determinação da máxima fase estável de lactato em natação), conteúdo pancreático de insulina; peso e concentração de lipídios totais no tecido adiposo de diferentes regiões e concentrações séricas de glicose, insulina, triglicerídeos, colesterol total, colesterol LDL, colesterol HDL. Constatou-se que a dieta rica em frutose conduziu os animais a resistência à insulina. O grupo FP apresentou dislipidemia, com aumento nas concentrações séricas de colesterol total e triglicerídeos, mostrando que o modelo animal avaliado é potencialmente interessante para o estudo da síndrome metabólica.

Le présent travail intitulé « Réflexions sur l’enseignement de la langue portugaise aux étrangers et sur l’enseignement de la langue portugaise aux natifs », a eu pour objectif d’enquêter sur les consensus et les désacords dans l’enseignement de la langue portugaise aux differents interlocuteurs. Des lectures préalables sur des textes de difusion scientifique qui ont pour but de divulguer des expériences sur l’enseignement du portugais aux étangers ont révélé l’importance atribuée à la connaisance de la culture quand il s’agit d’enseigner une langue donnée à de tels interlocuteurs. La connaissance de la culture est très importante dans ce cas de figure car il s’agit d’une conception plus ample : celle de l’interculturalisme. C’est pourquoi, nous faisons des lectures préalables dont la méthodologie proposée pour l’enseignement de la langue portugaise aux étrangers s’organise d’une telle façon que l’interlocuteur se trouve immergé dans la culture locale. Néanmoins, quand il s’agit de réfléchir à l’enseignement de la langue portugaise dédié aux natifs et basé sur les propositions curriculaires de la langue portugaise au collège et au lycée, datés de 1993 e 1998, qui constituent des textes de vulgarisation scientifique, on peut constater la préoccupation à réfléchir sur les conceptions de langage, langue, discours, texte et grammaire, des connaissances considérées comme importantes à la proposition de methodologies de l’enseignement de la langue portugaise dans le contexte très formel de l’enseignement scolaire. Le principal objectif de ce travail a consisté à analyser l’importance de la culture dans l’enseignement de la langue portugaise aux étrangers et natifs, le rapport entre culture, language, langue, discours, texte et grammaire dans l’enseignement du portugais aux étrangers et du portugais aux natifs, ainsi qu’à identifier le poids ...

By showing the absence of concern from schools in developing with students any kind of orality work, and the major importance they give only to reading and writing, this research shows an investigation on how the oral communication is established as learning content and how such education is conceived in the early years of elementary school, verifying if there is balance between the time devoted to written and spoken language activities, and how the oral language is treated in the classroom, this research also identifies which and how the oral genres are used, moreover, see if the teacher explores the emerging students‘ speech during class. This research was held in a government school in Bauru (SP), using three instruments to collect data: direct observation, videotaping observed classes, and a questionnaire. The observation and filming were done in only one classroom, a 3rd year of elementary school, in Portuguese classes; however, the questionnaire was applied to all school teachers, in order to have wider analytical conditions. The research´s approach is qualitative and ground on the bibliography study and field research. The analysis results indicate that school still emphasizes reading and writing method of teaching and does not work as bibliography authors propose in their researches about the studied topic; the reason is that this content has been applied to the curriculum recently, the teachers lack of clarity in some important concepts about speech and don´t have a bibliography basis
