Osteopenia diabética e pós-menopausa: efeito metabólico do zinco na recuperação do volume ósseo trabecular

Diabetes mellitus has been associated with bone metabolism alterations, such as osteopenia and osteporosis. So, the search of new anabolic agents promote bone mass gain can be important to prevent osteoporosis. The aim of this study was evaluate zinc anabolic effect over bone in diabetic and post-menopausal osteopenic models. Diabetes was induced by STZ (45mg/Kg of body weight) administration and post-menopausal by bilateral ovariectomy. Adults female Wistar rats (n=65) were divided in 5 groups: control group (n=15), ovariectomized without (n=15) and with zinc supplementation (n=10) groups, diabetic and ovarioctomized without (n=15) and with zinc supplementation (n=10) groups. Studied periods had been untill 90 days. Diabetic condition was confirmed hiperglicemic state and alterations of state with polyuria, polyphagia, polydipsia and glucosuria. Histomorphometric analysis showed that zinc supplementation increased trabecular thickness and reduced trabecular distance significantly in diabetic groups with similar values to those showed in control group. Correlation analysis of histomorphometric parameters with serum glucose concentration showed that more time in hyperglycemia more bone damage, as well as, zinc supplementation contributed to prevent this damage. Elevated serum glucose caused hyperzincuria, phosphaturia and calciuria. Zinc supplementation promoted increased levels of calcium and phosphorous ions in 90th days diabetic group. No alteration was observed by ovariectomy in mineral (Ca, P and Zn) serum and urine concentrations. Total serum Alkaline Phosphatase activity increased in diabetic groups, supplemented or not, compared with control group. However, Tartarate-Resistant Acid Phosphatase, magnesium and serum zinc did not altered in studied groups. Serum albumin was reduced only in diabetic groups. Serum creatinine was unaltered. These results support the hypotesis that zinc can be used to prevent and treat diabetic and post-menopausal osteopenia

A guerra midiática contra a Venezuela de Hugo Chavez: a cobertura da revista veja (1998-2002)

A pretensão deste trabalho foi o de analisar o discurso da revista semanal Veja sobre o governo de Hugo Chávez Frías, atual presidente da República Bolivariana da Venezuela. Através da leitura das reportagens, procuramos apresentar o comportamento da revista em relação ao se governo e a forma que sua política é classificada, representada. Reunimos edições da revista, entre 1998 a 2002, início do seu governo - eleito em dezembro de 1998, toma posse no início de 1999, período da tentativa de golpe (frustrada) em abril de 2002. O trabalho procura mostrar como as matérias não são isentas e que há um claro posicionamento ideológico da revista, que se insere no conjunto mais geral da mídia conservadora e anti-Chávez. O presidente, eleito e reeleito democraticamente, aparece sempre nas diversas reportagens da revista caracterizado como golpista, ditador, populista, fanfarrão. O nosso objetivo é o de revelar como Veja criou uma imagem negativa do presidente da Venezuela, coerente com os princípios neoliberais defendidos pela revista. A Venezuela com Hugo Chávez, com a chamada Revolução Bolivariana , realiza uma experiência singular de governo num país de larga tradição antidemocrática e afirma caminhar na contracorrente do pensamento hegemônico neoliberal. Em contrapartida, a revista Veja se apresenta com um representante da burguesia financeira e importante sujeito na construção e continuidade do neoliberalismo

Identificação de genes cry de Bacillus thuringiensis no controle de Sphenophorus levis, o bicudo da cana-de-açúcar

A bactéria B. thuringiensis caracteriza-se pela produção de proteínas tóxicas a representantes de diversas ordens de insetos, as quais são codificadas por genes cry. Este trabalho foi realizado com objetivo de selecionar isolados de B. thuringiensis, por meio da caracterização morfológica e molecular, identificando as diferentes subclasses dos genes cry3 e cry35 e determinar a patogenicidade contra Sphenophorus levis, uma das mais importantes pragas da cultura da cana-de-açúcar. Foram utilizados 1163 isolados de B. thuringiensis e com a observação em microscópio com contraste de fases foram confirmadas como pertencentes à espécie de B. thuringiensis. O material genético foi purificado pela matriz de troca iônica Instagene Matrix e submetido a PCR com iniciadores gerais cry3 e cry35 identificando-se 30 isolados contendo genes com potencial para o controle de coleópteros, os quais juntamente com as linhagens-padrão de B. thuringiensis var. tenebrionis, B. thuringiensis var. morrissone e B. thuringiensis var. tolworthi foram utilizados para a realização do bioensaio. Através de análise discriminante alocaram-se os isolados em quatro grupos quanto à toxicidade de B. thuringiensis. Os grupos ficaram assim definidos: um grupo que promovem até 10% de mortalidade contendo as testemunhas e duas linhagens;um grupo que causou 39% de mortalidade contendo três linhagens padrão e dez isolados; um grupo com 52% de mortalidade contendo treze isolados e um grupo com 70% de mortalidade contendo cinco isolados, os quais devem ser considerados promissores no controle biológico de S. levis.

Bispectral index in dogs at three intravenous infusion rates of propofol

Objective To establish the correlation between the bispectral index (BIS) and different rates of infusion of propofol in dogs.Study design Prospective experimental trial.Animals Eight adult dogs weighing 6-20 kg.Methods Eight animals underwent three treatments at intervals of 20 days. Propofol was used for induction of anesthesia (10 mg kg(-1) IV), followed by a continuous rate infusion (CRI) at 0.2 mg kg(-1) minute(-1) (P2), 0.4 mg kg(-1) minute(-1) (P4) or 0.8 mg kg(-1) minute(-1) (P8) for 55 minutes. The BIS values were measured at 10, 20, 30, 40, and 50 minutes (T10, T20, T30, T40, and T50, respectively) after the CRI of propofol was started. Numeric data were submitted to analysis of variance followed by Tukey test (p < 0.05).Results The BIS differed significantly among groups at T40, when P8 was lower than P2 and P4. At T50, P8 was lower than P2. The electromyographic activity (EMG) in P2 and P4 was higher than P8 at T40 and T50.Conclusion An increase in propofol infusion rates decreases the BIS values and EMG.

Uma educação tecida no corpo

In theory say the education as a knot of meanings made in the body. We take as a reference for demonstration of this argument the shows Folguedos, Guarnicê and Flor do Lírio and built within such spectacles cultural, symbolic and aesthetic meanings, which reveal the education woven in the body. Education that can happen not only in the formal space like the classroom or the university, but also in the area of art and the inclusion of individuals in the world of culture. So during the construction of the thesis we reflect on the following issues: what is the construction of culture and art that have in the Parafolclórico group? What way theses shows in their buildings bring significant elements that might compose an educational activity. How objectives sought asking the dichotomies present in the concepts of art and culture; critically systematize a work of artistic, cultural and educational production in the group, in addition to expanding the understanding of education, considering the body experiences. The phenomenological attitude of Merleau-Ponty, is a reference methodology of this study, which places the reference knowledge as a result of our experience in the world, our world lived. Thus, this study considers the experience of the researcher in the three shows in tariff, represented by scenes described, as a dancer and spectator. Therefore we understand that Folguedos, Guarnicê and Flor do Lírio in their artistic, aesthetic and cultural languages, allow many meanings that occur in the body, which invites the perception and extend the experience of the subject, demonstrating an education that allows sight and knowledge, seeking new sensations and experiences, we show our intimacy with the world, with the objects and with the other. The art is understood as virtuality, as a human creation that carries the reality and that allows many readings and experiences, each perception can recognize and know new horizons, having as base and material the culture. This entails the heterogeneous, is not closed but that individuals can interpret it entered and recognize the symbols they created the same way, confirming a unit. The art and culture show us significant evidences of an education woven in the body

Foram coletados 570 nematódeos Filaroidea de 36 capivaras, sacrificadas entre 1989 e 1996, onze jovens menores que seis meses e 25 adultas, provenientes da região do pantanal do Mato Grosso do Sul (Paiaguás). Cento e setenta e seis (176) espécimes de Yatesia hydrochoerus foram encontrados nas fáscias dos músculos esqueléticos, principalmente da região do obliquus externus abdominis e na face interna dos membros posteriores e trezentos e noventa e quatro (394) espécimes de Cruorifilaria tuberocauda foram coletados das artérias renais (380) e das artérias pulmonares (14) dos animais.

A dança dos monstros: corpo e estética na arte e na Educação Física

The speeches about the body in interface with the technology, that fulfill the contemporary discussions, have been a stage of innumerable ethical, epistemological, aesthetic and ontological reflections. These happened bodies of the biotechnological scene also invade the dance, making several possible dialogues, making old concepts instable, opening way to revealing explorations and bringing with it implications and reflections. In this context, this research has as objective to discuss relations between body and technology in the dance; to understand the aesthetic configurations of the monster in the dance as possibility to question the body; to establish relations between the monstrous body in the dance and the conceptions of body in the Physical Education. We believe to be able to contribute for the reflection in the field of the Physical Education, since the work visualizes to extend the field of the discussions on aesthetic body and, as well as evidencing dialogues between different areas of the knowledge, as the Art and the Physical Education. From the point of view of the method, the work follows orientation of the Phenomenology for an aesthetic image appreciation of the videos in the choreographies In'perfeito and Violência of Cena 11, Dance Group that has marked new aesthetic configurations in the brazilian dance. Thus, we took for us the reflections on the "significant scenes" proposed by Bicudo (2000), to appreciate the dance of Cena 11. We emphasize that, after the identification of the Significant Scenes, it was necessary to approach these scenes from close senses, from which we detach the appearance, the space and the gesture. We evidence that, the bodies revealed by the group Cena 11, show an aesthetic that it interlaces the beauty, the ugly and the grotesque. An aesthetic of the unharmony, capable to transgress the oppositions, dialoguing with multiple antagonisms and that it amplifies the apollonian aesthetic linear rules, so predominant in the history of the dance and the Physical Education. We identify some indicatives that take us to the problematizations on an affective and anarchic body, when questioning the tyranny of the perfect corporality; the naturalization of the pain; the closed gesture in a finished and unique grammar; the standardization of feminine and masculine roles and the negation of the feeling. From these indicatives, we discuss the aesthetic of the deformed bodies of Cena 11, approaching it of the conceptions of body in the Physical Education, sometimes criticizing the rationalists and naturalistic views, sometimes dialoguing with more recent perspectives studied by researchers of this area of knowledge, which point to a reflection on the body under the optics of the sensible

Beleza e poder na Ginástica Rítmica: reflexões para a educação física

La beauté dans la Gymnastique Rythmique (GR) s est esquissée comme condition de son existence. Pour son analyse, nous avons eu recourt au discours sur le pouvoir de Foucault (1971, 1979, 1987, 1988, 1997, 2003) et à sa relation avec la production de savoirs. Basés sur cette compréhension, nous avons réfléchi sur les relations de pouvoir dans la GR qui se sont établies et consolidées grâce à la réglementation de sa pratique, dans lequel le Code de Pointage a un rôle prépondérant. Ainsi, la GR a construit sa beauté à travers les temps au moyen de jeux de force où la gestualité de corps performatiques, à travers la discipline, a été prépondérant. Cette dernière a configuré des sens attelés à la coercition-résistence des corps: la production de discours. C est en pensant à une beauté comme ume trame de discours construits par ces relations de pouvoir-savoir des investissements du corps dans la Gymanstique Rythmique que nous nous posons les questions: Comment le Code de Pointage réglemente la gymanstique rythmique et sportive au sujet de la construction de la beauté ? Quelle est la relation entre les pouvoirs et les savoirs impliqués dans cette réglementation ? Nous avons donc pour objectifs de rechercher la beauté dans la Gymnastique Rythmique comme savoir produit à partir des relations du pouvoir circonscrites dans les règles de la modalité et de discuter la beauté à partir de la relation pouvoir/savoir comme réflexion pour le milieu de l éducation physique. Nous avons utilisé comme méthodologie la technique de l analyse de contenu (Bardin, 1977) afin d analyser le Code de Pointage de la GR dans sa version 2005-2008. Nous avons également fait usage des images de gymnastes comme moyen analogique pour amplifier le sens des discussions. La lecture fluctuante nous a permis de sélectionner des unités significatives et d organiser nos discussions en trois axes thématiques qui composent le premier chapitre intitulé « La beauté réglementée ». Dans ce chapitre, nous discutons les spécificités de la GR, la prescription de l utilisation du temps et de l espace et la configuration du geste technique à partir de l analyse de son code de ponctuation. Dans le deuxième chapitre, « Le corps beau transcende la règle », nous réalisons quelques réflexions destinées à l éducation physique à partir de la discussion du chapitre antérieur en prenant pour cible trois sujets : Pouvoirs et Savoirs, Technique et Style, Beauté et Éducation. Nous avons ainsi constaté que la beauté de la Gymnastique Rythmique contemporaine est entourée par sa réglementation, mais a été et continue à être dessinée par des mécanismes de pouvoir-savoir tout au long de sa trajectoire historique. Malgré l existence de conditions pour la beauté dans le Code de Pointage de la GR, il existe la possibilité de la création du propre style par la gymnaste, par la possibilité de vivre l improvisé et l imprévu, de sensibiliser le public, parce que le pouvoir crée des savoirs et le corps, qui se dépasse, créera toujours de nouvelles formes d être beau. La constatation que le Code de Pointage produit une beauté et que la gymnaste la reconstruit continuellement en en réactualisant les règles est une réflexion importante pour l éducation physique: elle réaffirme que le corps n est jamais seulement soumis, que même dans la soumission il est capable de produir du savoir, d être beau et de créer de nouveaux sens pour la Culture de Mouvements

Desempenho reprodutivo, características do pelame e taxa de sudação em vacas da raça Braford

Foram investigados os efeitos das características do pelame e da taxa de sudação (TS) sobre o intervalo de partos (IEP, n = 423) e os dias para o parto (DPP, n = 1.202) de vacas da raça Braford criadas em sistema extensivo em região tropical úmida no Mato Grosso do Sul, Brasil. As análises foram realizadas pelo método dos quadrados mínimos considerando para intervalo de partos os seguintes efeitos das classes de idade da vaca ao parto: grupo genético; pai; e regressão sobre a refletância da superfície da capa (R), a espessura da capa (E), o comprimento dos pêlos (C), o número de pêlos por unidade de área (N), o diâmetro dos pêlos (D) e a taxa de sudação. Para dias para o parto, foram considerados os efeitos: R, E, C, N, D, TS, divididos em classes; grupo genético; idade no início da estação de monta; e pai. Os componentes de variância e co-variância foram estimados pelo método de Máxima Verossimilhança Restrita sob o modelo touro. As características adaptativas não foram importantes para a variação do intervalo de parto e dos dias para o parto, mas a taxa de sudação apresentou efeito importante sobre dias ao parto. As estimativas de herdabilidade foram quase nulas para IEP e DPP e maiores para as características adaptativas (E = 0,16 ± 0,09; C = 0,18 ± 0,09; N = 0,08 ± 0,06; D = 0,12 ± 0,07; R = 0,30 ± 0,12; TS = 0,10 ± 0,06). Os resultados obtidos para as correlações genéticas de IEP e DPP com TS e entre as características do pelame indicaram que a seleção simultânea para menores valores de C pode ser favorável à redução do intervalo de partos. em geral, as correlações genéticas entre TS, IEP e DPP apresentaram elevado erro-padrão. Considerando os resultados deste estudo e a importância das características do pelame e da sudação, confirma-se a necessidade de se estudarem as correlações genéticas entre as características adaptativas e o desempenho reprodutivo para o progresso da adaptação de bovinos da raça Braford no Brasil.

Proposta Curricular para Educação infantil: (re) significando saberes docentes

The theory contemporary in the field of early children education, as well the legal discourse and official texts valid in our country point to the need for systematization of proposals pedagogic / curriculum in institutions, built and carried out by subjects that act as factor of assurance care quality. Quest us about what knowledge are required to teachers in developing a proposed curriculum for children education. Defined as an object of study, the knowledge teachers necessary for the development of a proposed curriculum for children education. As goals, assume: investigate teachers knowledge necessary for the development of a proposed curriculum in a Public Institution for children education and contribute to the (new) meaning on the part of teachers, knowledge needed to build a proposed curriculum for children education. Assuming the principles of the paradigm of qualitative research, we have developed a research institution of a children education Network Public Hall of Ceará-Mirim-RN, which serves children of four and five years old (preschool) with the participation of 17 teachers and two supervisory (teachers) that institution - subject of our research. Therefore, we have adopted the principles of action research, according to which the knowledge gained through research should build so shared / dialogue in the relationship between researcher and participants, what is the implementation of an effective action formative. As the search procedures developed observations no-teaching participants in the meetings and activities of the classroom; semi-structured interviews (individual and collective) with teachers and supervisors; analysis of school documents and participant observation in the seminars of studies reflective. The latter is implemented as key moments of speech and thought, and finally to (new) meaning of knowledge, the subject of the research-action. For these knowledge, the systematization of the register built was developed based on the principles of analysis of Content that guided us to the definition of two categories 1) knowledge teachers concerning conceptions of curriculum / proposed curriculum and 2) knowledge teachers concerning specifics of children education. From these were built subs representing thematings more specific and significant, among the many that emerged in the analysis: 1.1) Definitions of curriculum and curriculum proposal; 1.2) The subjects makers / implementing a curriculum / proposed curriculum; 1.3) elements constituting a curriculum / proposed curriculum for children education and 2.1) Functions of children education and conception of child; 2.2) The space of the play in the organization of routine. Under the intervention could significant advances with regard to (new) meaning of such knowledge from the subjects, with major disruptions to their original designs. These are presented and reflected in this work. In front of this movement, transformation, made the need for a permanent work in the context of the institution of in-service training, or mediated by pedagogical coordinator or other to assume this role with teachers, in order to provide the development and effectiveness of proposed curriculum consistent and contextualized in practice effective with the children concrete envisage the service to their specificities and a quality education

Pastoril: uma educação celebrada no corpo e no riso

By means of the Pastoral one an Education celebrated in the body and the laugh, visible is unmasked by means of cançonetas and of the licentious gesticulations of the jokers of this idleness. For such, we support ourselves in the phenomenological of Merleau-Ponty, the tradition and transmission of the verbal as it is conceived by Paul Zumthor, as well as in the phenomenology of the memory of the jokers and in the studies of cultural history and the philosophy of the body. The objective research to argue the body and the laugh as learning of the culture, as well as carrying through the production of a cartography of the potiguar pastoral ones, in the direction to argue the elements of the licentious gesticulations for the look and of cançonetas for hearing. The research is of phenomenological nature and when appealing the Phenomenology as an attitude, recognizes our look on the phenomenon, what if we show for while searching citizens and we assume the reduction and the lived world as methodological boarding to think the searched phenomenon. As he was evidenced in this study, one searched to dimensional the reach of a reflection centered in the body and the laugh through the listening of cançonetas of the Pastoral one and the vision through the licentious gestures; a reflection centered in the body of the joker of Pastoral
