Abstract: In a prospective, controlled study, 36 mother-child pairs from HIV+ mothers and 15 HIV-uninfected mothers were studied. Hematological features and cytokine profiles of mothers at 35 weeks of pregnancy were examined. Maternal and cord lymphocyte subsets as well as B-cell maturation in cord blood were analyzed by flow cytometry. The non-stimulated, as well as BCG- and PHA-stimulated production of IL2, IL4, IL7, IL10, IL12, IFN-γ and TNF-alpha in mononuclear cell cultures from mothers and infants were quantified using ELISA.After one year follow-up none of the exposed infants became seropositive for HIV. An increase in B lymphocytes, especially the CD19/CD5+ ones, was observed in cord blood of HIV-exposed newborns. Children of HIV+ hard drug using mothers had also an increase of immature B-cells. Cord blood mononuclear cells of HIV-exposed newborns produced less IL-4 and IL-7 and more IL-10 and IFN-γ in culture than those of uninfected mothers. Cytokine values in supernatants were similar in infants and their mothers except for IFN-γ and TNF-alpha that were higher in HIV+ mothers, especially in drug abusing ones. Cord blood CD19/CD5+ lymphocytes showed a positive correlation with cord IL-7 and IL-10. A higher maternal age and smoking was associated with a decrease of cord blood CD4+ cells.in uninfected infants born to HIV+ women, several immunological abnormalities were found, related to the residual maternal immune changes induced by the HIV infection and those associated with antiretroviral treatment. Maternal smoking was associated to changes in cord CD3/CD4 lymphocytes and maternal hard drug abuse was associated with more pronounced changes in the cord B cell line.HIV infection is associated with a complex pattern of changes in the hemopoietic and the immune systems, resulting in abnormalities of peripheral blood (PB) counts and changes in T and B lymphocytes. Decrease of T helper and increase of cytotoxic lymphocytes, profound changes in the cytokine profile and a

Abstract: The analysis of kinetic parameters for absorption of ions (NO3? e NH4+) is the main experimental procedure for the differentiation of the efficiency of absorption of these nutrients between corn species and cultivars. This work had the aim of evaluating the kinetic parameters of ammonium uptake to elucidate metabolic strategies of corn cultivars at environments with low and high nitrogen concentrations. The selected cultivars were: Catet o, Sol da Manh , Eldorado and BR 473. The plants were cultivated in pots with N solutions of 1.43 and 8.57 mM at green house conditions. The following kinetic parameters were evaluated 28 days after germination: Vmax, KM and N-amino soluble fraction in the water, nitrate and ammonium. Fresh mass of above groud part and roots, and N-total, P, and Mg in the dried material were determined. Sol da Manh cultivar presented high development at high affinity uptake systems, while Catet o and Eldorado cultivars presented high development at the low affinity and high capacity of NH4+ uptake system. Sol da Manh cultivar presented high adaptation at low nitrogen availability conditions. The values of NH4+ uptake kinetic parameters, Vmax and KM can justify the high productivity of this cultivar described in the literature as efficient in nitrogen use. A análise dos parametros cinéticos de absor o de íons (NO3? e NH4+) é o principal procedimento experimental para a diferencia o da eficiência de absor o desses nutrientes entre espécies e variedades de milho. Este trabalho objetivou avaliar parametros relativos à cinética de absor o do am nio e o desempenho metabólico de variedades de milho em ambientes com alta e baixa disponibilidade de nitrogênio. As variedades testadas foram: Catet o, Sol da Manh , Eldorado e BR 473. O experimento foi conduzido em casa de vegeta o e as plantas foram cultivadas em vasos com solu es 1,43 e 8,57 mM de N .Aos 28 dias após germina o determinaram-se os parametros cinéticos Vmax e KM, e na fra o hidrossolúvel, quantificou-se N?amino, nitrato e am nio. Obteve-se a massa fresca da parte aérea e de raiz e, seguido com determina o do N?total, P e Mg no material seco. A variedade Sol da Manh apresentou maior desenvolvimento de sistemas de absor o de alta afinidade, enquanto, as variedades Catet o e Eldorado mostraram maior desenvolvimento para sistemas de baixa afinidade e alta capacidade de absor o de N-NH4+. A variedade Sol da Manh apresentou maior adapta o do sistema de absor o à condi o de menor disponibilidade de nitrogênio. Os valores obtidos para os parametros cinéticos como Vmax e KM

Abstract: A inser o do psicólogo no campo da saúde, mais especificamente no hospital geral, é discutida a partir da reflex o sobre o funcionamento da equipe interdisciplinar, com suas resistências, competitividade e corporativismos; as peculiaridades do atendimento na rede pública, considerando-se o sistema de saúde e a realidade social dos pacientes atendidos; e o modelo de atendimento psicológico priorizado na gradua o, que promove uma concep o abstrata e a-histórica do sujeito desvinculada do seu contexto sócio-político e cultural. This paper discusses the introduction of the Psychologist in health care, specifically in a General Hospital, talking as a starting point some considerations on the workings of an interdiciplinary professional group, its resistances, competitiveness and collectivism; the peculiarities of the Brazilian National Health care and the social reality of its patients; and the standardized model of psychological care adopted in graduate teaching, which leads to an abstract and a-historical conception of the individual disjointed from its social, political and cultural context.

Alfa : Revista de Linguística , 2009,
Abstract: O presente trabalho configura um estudo sobre o emprego das pausas preenchidas eh ( ) e uh ( ) por brasileiros falantes de inglês como língua estrangeira em entrevistas do Teste de Profi ciência Oral em Língua Inglesa (TEPOLI). O estudo fundamenta-se sobre a teoria da Fonologia Prosódica de Nespor e Vogel (1986) e sobre os estudos de pausas preenchidas e o conceito de fluência de Moniz (2006), Merlo (2006) e Scarpa (1995). A investiga o comp e-se de um olhar triplo: analisamos a escolha de eh e uh como sons preenchedores; investigamos os contextos prosódicos das pausas preenchidas; e examinamos a motiva o cognitivo-discursiva para a inser o dessas pausas preenchidas. Os dados embasam uma reflex o sobre o conceito de fluência e oferecem maior poder descritivo à escala do teste, contribuindo, portanto, para seus estudos de validade e confiabilidade.
EXPERIêNCIAS COM AS IDENTIDADES GOIANAS NO ENSINO FUNDAMENTAL DE GEOGRAFIA
Joyce Almeida Borges
Boletim Goiano de Geografia , 2009,
Abstract: Este artigo tem por objetivo discutir como as identidades goianas s o abordadas no ensino de Geografia em Goiania, e como os alunos concebem o que é ser goiano, e o que faz parte de suas identidades. Ao longo dele identificamos as contribui es da educa o na constru o dos discursos identitários tendo como referência a percep o de estudantes e professores. As problemáticas que se pressup em em torno do tema s o de que na contemporaneidade é necessário discutir a diversidade cultural, os conflitos identitários socioculturais e territoriais para que os estudantes possam se reconhecer enquanto sujeito sociocultural, construindo um ambiente de respeito às diferentes identidades. Porém, aliar tais temáticas ao ensino de Geografia é um desafio. A princípio foi identificado que os livros didáticos n o apontam os referentes temas e nem a realidade cultural goiana em suas interpreta es geográficas. Professores e estudantes deram depoimentos sobre essa realidade no ensino de Geografia. Os procedimentos metodológicos utilizados para a realiza o do artigo foram leituras, técnicas diretas ao campo, entrevistas, questionários, mapas mentais, relatos e fotos.
