Despite of the technological advances that favor the transplant process, there are issues of effectiveness of care necessary for the maintenance of potential organ donors with brain death, which contribute to the no realization of transplants of organs and tissues of these patients. It is presupposed that the problems could be related to perceptions and understandings that the professionals of the units of internment have about the care required by the diagnosis of brain death. The aim of this study was to understand the meaning of the nursing care of the potential organ donor with brain death to the nursing staff. Descriptive study with qualitative approach guided by Action Science Theory and the critic-reflexive research methodology accomplished with five nurses and 19 nursing technicians from Operative Rehabilitation Center in a public hospital at Natal / RN, Brazil, between March and May 2013. Data were collected through semi-structured interviews with individual reflection about the care and through group interview, after approval by the Ethics and Research Committee, CAAE No.: 04255612.7.0000.5537. The analysis was performed in a thematic way according to Bardin. During the group meeting the participants were driven in a discussion about the need for change and how to perform them. The results indicate that the professionals actions are consistent with those required for maintenance of potential organ donors, although the material and human resources are not adequate. That situation leads the professionals to develop a meaning of care as one labor more, demanding more than they can give. They express beliefs and feelings concerning the hope that their care brings a greater good that is to save lives. The reflection for a possible change of action was difficult to accomplish due to professionals not to be able to self evaluate, what lead to direct your changes suggestions for other team members. It is concluded that the care provided to these patients is a difficult care, evidenced by suffering both death situation of the person cared and pain of their families, as the dehumanizing conditions of work, helping themselves to keep distance from patients to not suffer so much. The knowledge impregnated in their act, are scientific, ethical, aesthetic and personal kind with a predominance of the scientific followed by the personal. The study was also relevant to the practice of nursing in maintaining the potential donor, in that it allowed the identification of the knowledge used by nurses in their care practice and the meaning understanding of the professionals on the care provided, as a good action that brings satisfaction when the transplanting is executed. Other experiences are suggested with the critic-reflexive research methodology, both in research as in teaching nursing

As alterações que envolvem as globinas devem-se a modificações em genes responsáveis pela seqüência e estrutura das cadeias polipeptídicas, bem como aos genes reguladores da síntese destas cadeias. Hemoglobinas variantes apresentam estrutura química diferente da hemoglobina normal correspondente, resultante de mutações em uma ou mais bases nitrogenadas, ocasionando a troca de aminoácidos nas globinas alfa, beta, delta ou gama. A hemoglobina N-Baltimore é uma variante de globina beta, com substituição da lisina, na posição 95, por ácido glutâmico, apresentando mobilidade eletroforética mais rápida que a hemoglobina A em pH alcalino. Nas análises eletroforéticas em pH alcalino realizadas em doadores de sangue do Hemocentro de São José do Rio Preto (SP) identificamos a presença de portador de hemoglobina rápida em heterozigose, posteriormente confirmada por focalização isoelétrica e cromatografia líquida de alta pressão (HPLC). Os estudos de hemoglobinas anormais em doadores de sangue permitem a identificação de variantes raras e possibilitam o aconselhamento genético adequado a cada caso com estudo familial.

An experiment was conducted to study the in vitro digestibility of dry matter (IVDMD) and gross energy (IVGED) of hydrolyzed sugarcane bagasse with different storage times and two periods of adaptation of the bovine to the diet. A completely randomized design with four treatments and five replications was used. Treatments A,B,C, and D which corresponded to the times of 0, 15, 30, and 45 days of storage time period of the bagasse, respectively. Each treatment was studied at 7 and 45 after adaptation of the bovine ruminal donor to the diet. After 30 days storage, the bagasse IVDMD was inpaired for both 7 and 45 days of adaptation. Averages values of 25.8; 25.9; 23.1 and 23.3% were obtained for IVDMD with seven days of adaptation, and 25.04; 21.6; 12.5 and 11.4% with 45 days of adaptation for storage periods of 0; 15; 30 and 45 days, respectively. For IVGED, the averages obtained were 33.4; 27.8; 30.9; and 27.2% with seven days, and 30; 26.6; 20.6 and 14.5% with 45 days of adaptation for storage periods of 0, 15, 30 and 45 days, respectively.

Frente às dificuldades para captação de bolsas de sangue pelos hemocentros, são utilizados os mais diversos meios para sensibilizar os doadores e manter abastecidos os bancos de sangue. Este trabalho apresenta a “simulação parcial” dessa realidade, através de um jogo educativo eletrônico que objetiva informar e conscientizar sobre a importância da doação. Trata-se de um mecanismo de esclarecimento de dúvidas comuns e desmitificação de crenças disseminadas pela falta de conhecimento que dificultam a captação. Com o objetivo de informar o jogador e não somente entreter, “Em busca do doador perdido” é a apresentação de um tema comum em formato criativo, motivador e de impacto social. A simulação proporciona ao jogador experimentar as dificuldades de se encontrar doadores e desperta no mesmo o conhecimento sobre questões básicas do processo de doação. A partir de dois experimentos com doadores em potencial foi validada a proposta do jogo, como uma forma de conscientizar os jogadores sobre a importância da doação.

Neste trabalho, fizemos uma investigação sobre o estudo teórico das características I x V e C x V de Nanotubo Carbono de Parede Simples (NCPS) puro, com Nitrogênio substitucional carregado com cargas -1 (caracterizando um indicativo de dopagem tipo n) e +1 (caracterizando um indicativo de dopagem tipo p) e na presença de grupos doador (NO2)-aceitador (NH2), através da simulação computacional do estado fundamental de NCPS, bem como de sua estrutura eletrônica e propriedades ópticas, utilizando parametrizações semi-empíricas AM1 (Austin Mudel 1) e ZINDO/S-ClS (Zerner´s lntermediate Neglect of Differential Orbital/Spectroscopic - Cunfiguration lnteraction Single) derivadas da Teoria de Hartree-Fock baseada em técnicas de química quântica. Por meio deste modelo teórico analisamos as propriedades ópticas e eletrônicas, de maior interesse para esses materiais, a fim de se entender a melhor forma de interação desses materiais na fabricação de dispositivos eletrônicos, tais como TECs (Transistores de Efeito de Campo) ou em aplicações em optoeletrônica tais como DEL (Dispositivo Emissor de Luz). Observamos que NCPS com Nitrogênio substitucional apresentam defeitos conformacionais do tipo polarônico. Fizemos as curvas dos espectros UV-visível de Absorção para NCPS armchair e zigzag puro, com Nitrogênio substitucional carregado com cargas (-1 e +1) e na presença de grupos doador (NO2)-aceitador (NH2), quando perturbados por intensidades diferentes de campo elétrico. Verificamos que em NCPS zigzag ao aumentarmos a intensidade do campo elétrico, suas curvas sofrem grandes perturbações. Obtivemos as curvas p x E, I x V e C x V para esses NCPS, concluímos que NCPS armchair possui comportamento resistor, pois suas curvas são lineares e zigzag possui comportamento semelhante ao dos dispositivos eletrônicos importantes para o avanço tecnológico. Assim, nossos resultados estão de bom acordo com os resultados experimentais e teóricos de NCPS puro e com Nitrogênio encontrados na literatura.

Abstract Introduction: Indications for induction therapy is not consensual in living donors. Objective: The objective of this study was compare no induction with thymoglobulin and basiliximab induction in the incidence of acute rejection in kidney transplantation with living donor. Methods: We select all cases of renal transplantation with living donor performed in Hospital das Clínicas de Botucatu da UNESP during the period of January 2010 to December 2013. The group was divided by the type of medication used for induction. Results: A total of 90 patients were evaluated. There were no differences in baseline characteristics of age and underlying disease. The rate of biopsy-proven acute rejection was higher in the group without induction (42.9%) compared to basiliximab group (20%) and Thymoglobulin (16.7%), p = 0.04. The rejection by compatibility shows that the identical had the lower rejection rate (10%). The haploidentical group without induction had the highest rejection rates (53.3%). In all distinct group the rejection rates were similar with basiliximab or Thymoglobulin, p = NS. The use of induction therapy was associated independently with a lower risk of rejection (OR = 0.32 CI: 0.11 to 0.93, p = 0.036). There were no differences in renal function at 6 months and patient survival and graft in the three groups. Discussion: The haploidentical patients without induction were those with higher rates of acute rejection. The group of patients induced with Thymoglobulin had a higher immunological risk, however showed low rates of rejection. Conclusion: The use of induction therapy resulted in lower rates of rejection in transplantation with living donor.
