Effect of grain maturity stage on the quality of sorghum BRS-610 silages / Efeito do estádio de maturação dos grãos na qualidade das silagens do sorgo BRS-610

The quality of sorghum BRS-610 silages in seven stages of grain maturity, between the milky and dry stage, for determination of the ideal moment of ensilage was evaluated. The silos were open after 56 days of fermentation. The values for dry matter of silages increased from 199 to 473g/kg or from 19.9 to 47.3 percent, with the advance of stage maturity of grains. As for the quality of fermentation, the silages may be classified as excellent quality in every stage of maturity. The lower values of neutral detergent fiber, 539g/kg or 53.9 percent, and acid detergent fiber, 307g/kg or 30.7 percent, were observed between the milky/dough to dough/dent stages. Regression analysis indicated an increase in values of lignin - 0.3 unit por stage - and reduction in values of in vitro dry matter digestibility - -2.5 units por stage - with the advance of the grain's stage maturity. The ensilage of sorghum BRS-610 between the milky/dough and dough stage ensure very good fermentation and nutritive value of silage.

Os baixos valores de fibra detergente neutro, 539g/kg ou 53,9 por cento, e fibra detergente ácido, 307g/kg ou 30,7 por cento, foram observados entre os estádios leitoso/pastoso a pastoso/farináceo. A análise de regressão indicou aumento nos teores de lignina, 0,35 unidades por estádio, e redução nos valores de digestibilidade in vitro da matéria seca, -2,50 unidades por estádio, com o avanço do estádio de maturação dos grãos. A ensilagem do sorgo BRS-610 entre os estádios de grãos leitoso/pastoso a pastoso, garante excelente fermentação e bom valor nutricional da silagem.

Organ donation and transplantation from medical students' perspective: introducing the experience from an academic league in Brazil.

INTRODUCTION: Medical education is an important factor to decrease the waiting list for transplantation. Reports in the medical literature reveal limited notification of potential organ donors by general physicians. Appropriate information is also needed to increase the availability of potential donors and minimize the waiting list. This article describes the acquired experience with an extracurricular program of education on organ and tissue transplantation in our institution, searching to meet medical information needs using a format of an academic league. METHODS: This qualitative study describes a proposed approach on the theme of "transplant and organ and tissue donation" with medical students from a Brazilian university, through creation of a program named "Transplantation League" in direct association with a transplantation center. RESULTS: The league's activities are based on three main activities teaching, research, and practical. Besides the organization of the I Course of Organ and Tissue Transplantation, the project received financial support from the Federal University of Goiás to develop the assignments. A member's stake in the league included scientific projects involving liver transplantation candidates, as well as notification, donation, transportation, and transplantation of these patients. CONCLUSION: The academic league has the purpose of academic information on organ and tissues transplantation. Its application in medical schools may be valuable to increase transplant numbers.

Avaliação das silagens do sorgo BRS-610 em sete estádios de maturação pela técnica in vitro semiautomática de produção de gases / Evaluation of the silages of sorghum BRS-610 at seven stages of maturation by semi-automated in vitro gas production technique

Avaliou-se a qualidade da silagem do sorgo BRS-610 produzida em sete estádios de maturação dos grãos, pela técnica in vitro semiautomática de produção de gases. O delineamento foi inteiramente ao acaso, com quatro repetições por tratamento, e as médias foram comparadas pelo teste Scott-knott. Os parâmetros potencial máximo de produção de gases, tempo de colonização, taxa de produção de gases e degradabilidade efetiva da matéria seca para as taxas de passagem de 2, 5 e 8 por cento/h foram obtidos pelo modelo de France et al. O potencial máximo de produção de gases não diferiu entre as silagens e indicou média de 170,5mL/g de matéria seca. Entre leitoso/pastoso e pastoso houve menor tempo de colonização. As maiores taxas de fermentação foram observadas nas silagens produzida entre os estádios pastoso/farináceo a seco. As degradabilidades efetivas foram semelhantes entres as silagens, com média de 46,2 por cento. O sorgo BRS-610 produziu silagem de qualidade satisfatória, com destaque para a silagem produzida com a planta no estádio pastoso/farináceo, por associar melhor taxa de fermentação e menor tempo de colonização.

The quality of the silages of sorghum BRS-610 produced at seven stages of grain maturation was evaluated by the semi-automatic gas production technique. It was used a complete randomized design, with four repetitions per treatment, and the means were compared by the Scott-knott test (P<0.05). The potential of production of gases, lag phase, rates of gas production, and effective dry matter degradability for 2, 5, and 8 percent/h rates of passage were obtained by the model of France et al. The potential of gas production did not differ among the silages, showing mean of 170.5mL/dry matter. The stages between milky/soft dough to soft dough showed shorter lag phase. The highest rate of gas production was observed in the silages produced between soft dough/floury to dry stages. The effective degradabilities were similar among the silages, averaging 46.2 percent. The sorghum BRS-610 produced satisfactory quality silage, mainly for the silage produced with the plant at soft dough/floury stage, for associating better rate of gas production and shorter lag phase.

Report of initial experience in small bowel transplantation at São José do Rio Preto Medical School Hospital.

Intestinal failure is the patient's inability to maintain hydroelectric and nutritional support by the digestive route, arising from massive enterectomy or diseases in which the bowel is incapable of adequately absorbing fluids and nutrients. Patients with intestinal failure associated with short bowel syndrome (SBS) and with other functional diseases with malabsorption or with total parenteral nutrition-related complications (recurrent sepsis and thrombosis of one or more deep venous accesses) are candidates for small bowel transplantation (SBT), which can be an isolated small bowel, a combined liver and small bowel, or a multivisceral graft. At our institution, three isolated SBTs were performed as our initial experience with this transplant.
