Abstract: Effects of the interaction of irradiance and nutrient levels on growth and contents of photosynthetic pigments, carotenoids and proteins in Gracilaria domingensis (Kütz.) Sonder ex Dickie (Gracilariales, Rhodophyta) were investigated experimentally. Nutrient availability provided by dilutions of the nutrient solution of von Stosch (25 and 50%, which corresponded to nitrate concentrations of 125 and 250 μmol, respectively) and two photon flux densities [low PFD (50±5) and high PFD (100±5) μmol photons.m-2.s-1] were tested. Growth rates of G. domingensis were stimulated by high PFD. The interaction between high nutrient availability (50% VSES) and high PFD stimulated the accumulation of total soluble protein. Phycobiliprotein concentrations (phycoerythrin, phycocyanin, and allophycocyanin) and carotenoid contents were influenced by irradiance levels. Phycobiliprotein concentrations were higher at low PFD and high irradiances stimulated carotenoid accumulation. These results reflect the function of these pigments in photoprotection and the acclimation of G. domingensis to changes in irradiance levels. Our results indicate that light is a limiting factor for G. domingensis growth, that variations in phycobiliprotein contents under different irradiance levels are related to photoacclimation process, and that higher carotenoid contents at high irradiances are due to a photoprotection mechanism.

Abstract: in order to recommend corn hybrids for silage it is not enough to have high dry matter. it is also necessary that the silage presents high effective matter degradation (def) of the whole plant. this investigation had the objective of evaluating agronomic, bromatologic, and rumen degradability of dry matter of commercial corn hybrids, recommended for silage production, and also experimental hybrids from crosses of lines of high and low degradability. it was evaluated the performance of eighteen experimental hybrids and five commercial hybrids recommend for silage production. the experiment was established in 2003/2004 crop season in randomized block design with three replications. the experimental plot was constituted of four rows 5.0 meters long. corn plants were harvested at 20 cm from soil level at milk line at half grain stage. the silages were incubated in situ for 0, 6, 12, 24 and 96 hours in the rumen of three fistulated cows. effective degradability was calculated based on 0.05%/h of passage rate. it was observed that among cultivars there were hybrids, that present good potential for silage production with high effective matter degradation (def) of the whole plant, independently of grain texture. the strategy of synthesizing hybrids aiming at high dry matter effective degradability based on lines with high def is correct. the low correlation between effective degradability with a agronomic, and bromatologic characteristics indicate the need for better use of def in order to select corn hybrids of high quality of silage production.

Abstract: Composting is a way of transforming the organic waste into fertilizer, minimizing the use of inorganic compounds that may contaminate the environment. This transformation is the result of the microorganism action, converting complex carbon sources into energy. Enzymes that are exported by the microorganisms to the surrounding environment mediate this process. The aiming of the present work is to prospect the compost produced by the organic composting unit (OCU) of the Funda??o Parque Zoológico de S?o Paulo (FPZSP) to find novel starch hydrolyzing organisms (SHO) that secrete large amounts of amylases under harsh conditions, such as high temperature. We found five bacterial isolates that have amylolytic activity induced by soluble starch and 39°C temperature of growth. These bacterial strains were identified by MALDI-TOF (Matrix-assisted laser desorption/ionization-Time of Flight) analysis, a rapid and efficient methodology for microbe identification in large scale. Our results present amylolytic strains that belong to diverse taxonomic groups (Solibacillus silvestris, Arthrobacter arilaitensis, Isoptericola variabilis, and Acinetobacter calcoaceticus); some of them have never been associated with this kind of hydrolytic activity before. The information regarding enzyme induction will be important to optimize the production by the bacterial isolates, which may be a great value for biotechnological applications. 1. Introduction Amylases produced by plants, animals, and microorganisms have a wide range of industrial applications, such as pharmaceutical, animal feed, paper, textile, food industry, and renewable energy [1–3]. Most amylases used in industry are from microbial source due to several factors, for example, the great microbial genetic diversity present in the environment, high enzymatic activity in a wide range of conditions (extreme pH, temperature, osmolarity, pressure, etc.), and simple and cost effective production [4]. Industrial processes require robust enzymes, especially because large amounts of heat are generated during the process, accumulation of inhibitors, high salt concentrations, and so forth; therefore, hydrolytic microbes, which have their hydrolases induced by temperature, may produce thermotolerant enzymes and, consequently, are highly desirable [5, 6]. Composting is the transformation of residual organic matter into fertilizer accomplished by microorganism, which secrete, among other things, hydrolytic enzymes to assimilate diverse energy sources available in the substrate in order to survive. Compost piles can reach up to 80°C

Abstract: in vitro, the sensitivity to different propolis extracts, at a concentration of 100 mg/ml, of staphylococcus aureus, staphylococcus sp. coagulase negative, streptococcus agalactiae and bacteria of the coliform group, isolated from the milk of cows with mastitis, was evaluated using the technique of an agar disk diffusion with a medium doublelayer. the results showed that the commercial propolis, the ethanolic extract, and, in a minor proportion, the methanolic extract inhibited the growth of the gram positive bacteria, staphylococcus aureus, staphylococcus sp. coagulase negative and streptococcus agalactiae. the extracts obtained through water, etila acetate and chloroform did not inhibit any bacterial strains, nor did the pure ethanol and methanol vehicles that were utilized as controls. the gram negative bacterium tested, from the coliform group, did not show sensitivity to any extract. bacterial strains of the same species collected from different sources presented significant differences in sensitivity to the extracts (p < 0.05). in the streptococcus agalactiae samples, the diameters of the zone of inhibition around the disks were bigger than those observed for samples of staphylococcus aureus and staphylococcus sp. coagulase negative. the results of this experiment stimulate the continuation of studies on the use of propolis extracts, by means of using the appropriate vehicles for the treatment of bovine mastitis.

Abstract: the basic principle of the preemptive analgesia is the administration of analgesics before the occurrence of painful stimulus in order to prevent pain, reducing the analgesic dosage, and compare the dosage required after the painful stimulus. it acts preventing or reducing the "memory" in the pain pathway in central nervous system. preemptive analgesia may attenuate or prevent development of central sensibilization induced by surgery. this research aimed at evaluating the use of nonsteroidal anti-inflamatory (nsaid) ketoprofen as preemptive analgesic. sixteen dogs were used, of varied age, female and male, and surgery of thoracotomies, the dogs received ketoprofen in group k or distiled water as placebo in group p, before surgical stimulation, the end surgery the animals received placebo in the group k and group p received ketoprofen. parameters as cardiac and respiratory frequency, tidal volum and minute flow, blood gases and pain score were measured during six hours which followed the postoperative period. the utilized protocol has showed significative variations as bicarbonate and blood carbon dioxide, any significative statistical variations related in the pain scores. the results reported do not justify the use of nsaid ketoprofen as preemptive analgesic.

Abstract: O objetivo deste artigo é analisar as rela es estabelecidas entre o Santo Ofício de Goa e a popula o nativa, a partir da análise de cartas redigidas pelos inquisidores. O motivo do estabelecimento da Inquisi o de Goa (1560) foi a presen a de crist os-novos na índia suspeitos de judaizar, mas as persegui es aos suspeitos de praticar o gentilismo (ritos hindus realizados por crist os nativos) aumentaram a partir do final do século XVI. Destacaremos as práticas e as cren as dos crist os nativos que foram concebidas como uma amea a à consolida o de uma disciplina crist (ado o de valores e comportamentos crist os) no Oriente Português e demonstraremos quais os agentes que auxiliaram os inquisidores nesta tarefa. Constatamos que o Santo Ofício de Goa n o contou apenas com a colabora o de agentes europeus (bispos e membros de ordens religiosas), pois recebeu o auxílio de parte da popula o nativa.

Abstract: O estabelecimento do Tribunal da Inquisi ona Espanha (século XV) e em Portugal (séculoXVI) estimulou a migra o de judeus e decrist os-novos, que escolheram a índia comoum dos destinos. Porém, o Tribunal daInquisi o de Goa foi criado em 1560 paramanter a ortodoxia católica nos domíniosportugueses do Oriente, conquistados a partirda chegada de Vasco da Gama à índia em 1498.O objetivo do artigo é demonstrar apersegui o dos crist os-novos na índiaatravés da análise das cartas escritas pelosinquisidores. Os crist os-novos foram asprincipais vítimas da Inquisi o na PenínsulaIbérica e em Goa (no século XVI), masdenunciaram a arbitrariedade do Santo Ofícioa reis e a papas. Charles Dellon, um antigoprisioneiro do Santo Ofício de Goa, denunciouas arbitrariedades da Inquisi o e a publica ode seus relatos favoreceu o debate sobre atolerancia religiosa na Europa.
