Escolha da técnica cirúrgica para o tratamento da síndrome da cimitarra
CASTRO NETO Josué V.,CARVALHO Rubens J.,SOUSA Francisco Carlos C.,AGUIAR Marco Aurélio B.
Revista Brasileira de Cirurgia Cardiovascular , 1998,
Abstract: A síndrome da cimitarra, retorno an malo parcial da drenagem venosa pulmonar para veia cava inferior (VCI), é les o rara, raz o pela qual a maioria dos cirurgi es n o tem grande experiência com a técnica de corre o. Relatamos o caso de paciente do sexo feminino, com 29 anos de idade, com o diagnóstico de síndrome da cimitarra comprovado pelo cateterismo cardíaco, que revelava calibrosa veia an mala do pulm o direito em dire o à VCI e desembocando na jun o entre esta e o átrio direito. Para o tratamento cirúrgico optamos, inicialmente, pela técnica de Kirklin, porém os achados operatórios nos obrigaram a mudar de técnica, levando-nos a dividir a veia an mala e reimplantá-la na parede do átrio direito, conforme descrito por Cooley. S o técnicas diferentes com tempos distintos, prolongando, portanto, o tempo de opera o. Um dos objetivos deste trabalho é contribuir para o processo de decis o dos cirurgi es, já que a compara o entre as técnicas n o é encontrada na literatura.
PROTOTHECA ZOPFII: IMPORTANTE PATóGENO NA ETIOLOGIA DA MASTITE BOVINA NO BRASIL
Válter Ferreira Félix Bueno,Albenones José de Mesquita,Francisco de Carvalho Dias Filho
Ciência Animal Brasileira , 2006,
Abstract: A alga Prototheca zopfii destaca-se entre os agentes ambientais da mastite bovina em virtude dos prejuízos decorrentes do comprometimento da qualidade e produ o de leite. Além disso, apresenta elevada resistência antimicrobiana e potencial zoonótico, fatores que levam ao descarte dos animais infectados. Esse patógeno foi identificado recentemente em Goiás e acredita-se que possa estar presente em outros rebanhos do Estado. O presente estudo visa revisar a literatura referente às características do agente, aspectos econ micos e de saúde pública, epidemiologia, clínicos e patológicos, bem como os procedimentos para diagnóstico, controle e preven o dessa forma de mastite. PALAVRAS-CHAVE: Controle de mastite, epidemiologia, Prototheca zopfii.
Parasitismo e preda??o em ovos de Euschistus heros (Fab.) (Heteroptera: Pentatomidae) no Distrito Federal, Brasil
Medeiros, Maria A.;Schimidt, Francisco V.G.;Loiácono, Marta S.;Carvalho, Vinícius F.;Borges, Miguel;
Anais da Sociedade Entomológica do Brasil , 1997, DOI: 10.1590/S0301-80591997000200026
Abstract: the mortality of euschistus heros (f.) at the egg stage was studied at the field. the experiments were carried out in planaltina - d.f., brazil, in 1993 and 1994, on sunflower (helianthus annuus) cultivated following the soybean (glycine max) crop season. egg masses found in the field were marked and checked daily for four days, and taken to the laboratory to check the total number of eggs, eggs that failed to hatch and those parasitized or destroyed by predators. the incidence of parasitism in eggs of e. heros was high in 1993 (65%) and in 1994 (80%). five species of parasitoids were recovered: telenomus podisi ashmead, trissolcus basalis (wollaston), trissolcus teretis johnson, trissolcus urichi crawford (scelionidae) and eupelmus sp. (eupelmidae). t. podisi was the most frequent species. egg mortality due to predators was 17% in 1993 and 13% in 1994.

Revista Brasileira de Cirurgia Cardiovascular , 1998, DOI: 10.1590/S0102-76381998000300014
Abstract: the scimitar syndrome, anomalous drainage of pulmonary veins from the right lung to the inferior vena cava, is not a common pathology. most surgeons when faced with such a case have doubts about which surgical technique is best for its treatment. this paper shows some of the controversies in the surgical repair of this syndrome based upon one case successfully treated by us.
Desempenho e digestibilidade aparente em ovinos confinados alimentados com dietas contendo níveis crescentes de caro?o de algod?o integral
Cunha, Maria das Gra?as Gomes;Carvalho, Francisco Fernando Ramos de;Véras, Antonia Sherlanea Chaves;Batista, ?ngela Maria Vieira;
Revista Brasileira de Zootecnia , 2008, DOI: 10.1590/S1516-35982008000600022
Abstract: this work was carried out with the objective to evaluate the effects of different levels (0.0 20.0, 30.0 and 40.0%) of whole cottonseed (gossypium hirsutum l.) of the diet (% dm) on performance and nutrient digestibilities of feedlot santa inez sheep. twenty-four sheep with average initial and final body weight of 19.0 and 32.2 kg, respectively, and allotted to a completely randomized design, with four diets and six replications. the dry matter intake in kg/day, %bw and g/kg0.75 was not influenced by the inclusion of the whole cottonseed (wcs), with averages of 1.195, 4.61, and 104.07, respectively. the total and daily weight gains decreased, while the feed conversion ration showed increasing linear effect with the inclusion of wcs, except for the level of 20% wcs that showed similar performance to the control diet. the intakes of dry matter (dm), organic matter (om), crude protein (cp), total carbohydrates (tc) and total digestible nutrients (tdn), in g/day were not affected, while the neutral detergent fiber (ndf), acid detergent fiber (adf), ether extract (ee) presented increasing linear effect with the inclusion of wcs. the inclusion of whole cottonseed in the feeding provided quadratic effect for digestible coefficients of cp, adf and increasing linear effect for ndf and ee, however did not affect dm, om, tc and tdn intake of the diets. the whole cottonseed in the used levels does not alter the intake and the digestibility of the dm, ndf and tnd, but reduced the weight gain and feed conversion ratio of feedlot of the santa inez lambs, and could be included in termination diets.

Revista Brasileira de Zootecnia , 2002,
Abstract: O objetivo deste trabalho foi avaliar o consumo e a digestibilidade aparente de nutrientes em dietas com quatro níveis de substitui o do milho (0, 25, 50 e 75%) pelo farelo de palma forrageira. Dezesseis carneiros com 30 meses de idade e peso vivo médio de 40 kg foram alocados em delineamento inteiramente ao acaso. N o houve efeito dos níveis de substitui o do milho pelo farelo de palma sobre o consumo de nutrientes, o qual foi restrito em 2,5% do peso vivo. A inclus o do farelo de palma forrageira n o influenciou o coeficiente de digestibilidade aparente da matéria seca, matéria organica, fibra em detergente neutro, carboidratos totais, extrato etéreo e proteína bruta. O coeficiente de digestibilidade aparente da fibra em detergente ácido aumentou linearmente com a inclus o de palma forrageira na dieta.
Prioridades para investimentos em usinas elétricas
Carvalho, Joaquim Francisco de;
Estudos Avan?ados , 2008, DOI: 10.1590/S0103-40142008000300013
Abstract: due to reasons out of the scope of this article, important investments in the electric sector were delayed, increasing the risk of power shortages in brazil in the near future, with serious impacts on industrial production and quality of life. among the projects being studied by the ministry of energy to be operative in time to reduce that risk are the angra iii nuclear power plant and some hidro power plants in northern brazil, what raises doubts and provokes debates in the press, chiefly about the costs of the energy produced. in this article we try clear up some of these doubts.
O espa?o da energia nuclear no Brasil
Carvalho, Joaquim Francisco de;
Estudos Avan?ados , 2012, DOI: 10.1590/S0103-40142012000100021
Abstract: this article reviews the history and describes the experience on nuclear energy in brazil, showing that nuclear technology applied to biomedical sciences, industry and agriculture has been largely developed in this country, from the year 1950 on. then the paper shows that brazil can cover its electricity consumption with only renewable energy sources, without nuclear power plants. finally the arguments usually employed in the press, pro and against nuclear power plants are analyzed and some commercial and political aspects of the problem are commented. the sales strategy of the nuclear industry in brazil is also commented.
