ABSTRACT

Objetivou-se avaliar a degradação e a produção de gás de diferentes fontes proteicas geradas na cadeia produtiva do biodiesel em substituição à silagem de milho. Os tratamentos foram: coprodutos de Gossyypium hirsutum, Ricinus communis, Moringa oleifera, Jatropha curcas, Helianthus annus. Os produtos foram analisados mediante a técnica semiautomática de produção de gases in vitro. O coproduto da moringa apresentou maior taxa de degradação, quando comparado aos demais alimentos, porém apresentou baixa produção de gás e se tornou mais eficiente, sendo, portanto, indicado como o melhor nível (27,06%) de substituição à silagem de milho. O coproduto da mamona e o do algodão produziram a maior quantidade de gás em 48h de incubação. Todos os coprodutos estudados podem ser utilizados na dieta de ruminantes como alimento proteico até 30% de substituição à silagem de milho.(AU)


This study aimed to assess the degradation and gas production of different protein sources generated in the biodiesel production chain replacing corn silage. The treatments were byproducts Gossyypium hirsutum, Ricinus communis, Moringa oleifeira, Jatrophacurcas, and Helianthusannus. The products were analyzed by semi-automated technique of gas production in vitro. The coproduct moringa showed higher degradation rate compared to other foods, but showed low gas production, making it more efficient, being nominated as the best level of 27.06% by replacing corn silage. The byproducts of castor oil and cottonseed produced the largest amount of gas in 48 h of incubation. All studied byproducts can be used in the diet of ruminants as a protein food up to 30% by substitution of corn silage.(AU)

ABSTRACT

Local anesthetics (LA) belong to a class of pharmacological compounds that attenuate or eliminate pain by binding to the sodium channel of excitable membranes, blocking the influx of sodium ions and the propagation of the nerve impulse. S (-) bupivacaine (S(-)bvc) is a local anesthetic of amino-amide type, widely used in surgery and obstetrics for sustained peripheraland central nerve blockade. This article focuses on the characterization of an inclusion complex of S(-) bvc in2-hydroxypropyl- beta-cyclodextrin (HP-beta -CD). Differential scanning calorimetry, scanning electron microscopy andX-Ray diffraction analysis showed structural changes inthe complex. In preliminary toxicity studies, the cellviability tests revealed that the inclusion complex decreased the toxic effect (p smaller that 0.001) produced by S(-) bvc.These results suggest that the S(-) bvc:HP- beta-CD inclusion complex represents a promising agent for the treatment of regional pain.
