Abstract: O objetivo deste trabalho foi avaliar o efeito de inseticidas no controle da mosca-branca (Bemisia argentifolii Bellows & Perring, 1994) na incidência do vírus-do-mosaico-dourado e na produtividade do feijoeiro. Utilizou-se de tratamento de sementes com imidacloprid ou thiamethoxam, e de pulveriza es de inseticidas, em intervalos semanais. O experimento foi realizado no campo, em área irrigada, em Petrolina, PE, em blocos ao acaso, com cinco tratamentos e quatro repeti es. Houve redu o significativa no número médio de ovos, de ninfas e de adultos da mosca-branca e na porcentagem de infec o pelo vírus-do-mosaico-dourado do feijoeiro. A produtividade nas parcelas tratadas variou de 1.930 a 2.405 kg/ha, enquanto na testemunha foi de 1.490 kg/ha. N o foi observada diferen a significativa entre os tratamentos, no número de vagens/planta e peso de 100 sementes.

Abstract: a major issue influencing prescribing patterns of physicians has been the relative bioavailability and bioequivalence of commercial levothyroxine preparations. some studies have suggested similar bioequivalence between various l-t4 tablets while other reports have found differences. some of these studies have been criticized for methodological defects in patients' selection or study design, which have become appreciated only in retrospect. moreover the us pharmacopeia has proposed that commercial tablets of l-t4 should be tested for its dissolution in two different solutions. each manufacturer should periodically test batches of tablets as indicated. in the present study, we have compared serum thyroid function parameters (total t4, total t3, free t4, and serum tsh) in previously totally thyroidectomized patients, without sonographic evidence for reminiscent thyroid tissue in the cervical area. the above parameters were measured, as function of time, for 15 days of either an oral solution of l-t4 (100μg) or tablets of l-t4a and l-t4b (100μg/tablet). there was no significant difference between the various parameters, in relation to time, for each of the different preparations. moreover l-t4a tablets did not differ from l-t4b tablets, when those parameters were tested, either at the concentration of 100 or 200μg/day. we conclude that the two oral formulations of l-thyroxine have similar bioavailability and bioequivalence under the present experimental conditions.

Abstract:

The homeostasis is maintained by the immune system which is constituted a network of organs, cells and molecules that act to combating the assaults affecting the body. The immune function has been conceptually divided into innate immunity and acquired immunity. Among the effector cells of innate immunity are the natural killer cells (NK), they play an important role in the reproductive immunology in the establishment and maintenance of pregnancy and fetus. The study of the biological mechanisms involved in the maintenance of pregnancy contributes to increase knowledge about immune tolerance. The way in which the immune system is modulated, and the study of the recognition systems maternal innate and adaptive occurring during pregnancy, allow to understand the survival of the fetus. The aim of this review was to present the main functions of NK cells and describe their role in the process of trophoblastic invasion in the deployment process, in the maternal-fetal interaction and development of the fetus. The knowledge of the precise role of NK cells is necessary, because these cells may be responsible for reactions which lead to embryonic and fetal loss during the organogenesis process.

Abstract: Esta pesquisa teve como objetivo conhecer a intera o do casal em que um dos c njuges está na lista do transplante hepático. Foram entrevistados seis casais na faixa etária entre 24 a 77 anos, com tempo mínimo de convivência de quatro anos e espera na lista de transplante a partir de seis meses. As respostas foram analisadas de acordo com a Análise de Conteúdo Temática. Os resultados mostraram que: a entrada na lista do transplante foi vista como um momento de grande tens o e ansiedade, que persiste durante todo o tempo de espera; as necessidades encontradas foram a realiza o rápida do transplante e sanar dificuldades financeiras; paciência, compreens o, confian a, amor e a fé religiosa foram apontados como recursos para enfrentar a situa o; a rela o conjugal sofreu abalo, havendo casos que se caracterizaram por uma maior proximidade e, em outros, afastamento; os projetos e as expectativas de futuro mostraram-se aprisionados à espera do transplante. Conclui-se pela necessidade de um cuidado interdisciplinar que possibilite qualidade de vida ao casal.
água, organiza o do território e desertifica o na Tunísia: observa es a partir de um trabalho de campo Eau, organisation du territoire et désertification en Tunisie: observations à partir d’un travail de terrain Water, organization of territory and desertification in Tunisia: comments from a field work

Abstract: A desertifica o é um tipo de degrada o ambiental passível de ocorrer nas regi es de clima seco do mundo, principalmente em virtude da forma como se dá a explora o das terras aí localizadas. Grande parte da Tunísia encontra-se susceptível a esse impacto ambiental, levando em considera o que extens es consideráveis do seu território apresentam predomínio de uma pluviosidade muito baixa. Ainda assim, nem sempre a desertifica o se fará presente nessas terras, cuja presen a será determinada pelo tipo e intensidade do uso dos solos. O Trabalho de Campo desenvolvido na regi o centro-sul desse país, onde ocorrem os climas semiárido e árido, permitiu observar resultados diferentes em rela o a essa quest o ambiental. Em uma parte dessa regi o, técnicas de manejo dos solos e das águas utilizadas na organiza o do território praticadas a milhares de anos continuam a ser alternativas viáveis para dar sustentabilidade à agricultura e, juntamente com o uso de técnicas modernas, tem evitado o esgotamento dos solos e dos recursos hídricos. Esses exemplos mostram que a convivência com as secas, aliada a produ o econ mica de forma sustentável, é possível de ocorrer nesses ambientes, podendo algumas dessas técnicas serem reproduzidas no Brasil, particularmente na zona semiárida nordestina. Da mesma forma, o controle do movimento de dunas continentais foi outro aspecto positivo observado, também possível de ser reproduzido em algumas áreas do território brasileiro onde ocorre esse fen meno. Por outro lado, percebeu-se que a crescente necessidade de solos férteis e água para serem utilizados na agricultura comercial da Tunísia, vem expandindo essa atividade em dire o a algumas partes dessa regi o ainda pouco exploradas para esse fim e que apresentam esses recursos naturais, trazendo como consequência o recuo do uso tradicional dessas terras, baseado originalmente na pecuária extensiva, atividade que passa a se desenvolver mais intensamente em lugares onde os recursos hídricos e a vegeta o s o menos abundantes, provocando uma explora o mais acelerada dos mesmos, desenvolvendo a superpastagem e tornando a desertifica o uma marca cada vez mais presente em algumas paisagens dessa parte do país. La désertification est un type de dégradation environnementale pouvant survenir dans les régions du monde au climat sec, principalement en raison de la forme prise par l'exploitation des terres s'y trouvant. Une grande partie de la Tunisie est susceptible de subir cet impact environnemental, étant donné que des portions considérables de son territoire présentent en prédominance

Abstract: aiming to contribute to the current and intense process of revision of conceptions and educational practices mediating learning and development of young children in day care centers and pre-schools, and based on our research experiences at cindedi, this paper approaches several questions which, in our view, are relevant for the understanding of collective education. how does developmental research contribute to this discussion? what conceptions about development is it based on? which methodological perspectives are more promising for the comprehension of the ways children and their teachers act and change with their experiences? how to understand notions such as developmental stages, teachers’ role in the learning process, factors explaining infant development and developmental evaluations in infancy? both family and childcare professionals interact with the child and organize his/her environment according to their expectations about his/her development and their own role in this process. these expectations are built through their life experiences in their particular culture. many expectations, beliefs and psychological theories have, thus, a strong self-fulfilling power, helping to build competencies and deficiencies. children and the professional staff of child education institutions have undoubtedly much to gain from reflecting on these questions.
