Der volle Inhalt der QuelleThree trials were conducted to evaluate the effects of the inclusion of levels of whole cottonseed (WC) or soybean oil (SO) in diets for Nellore feedlot cattle. In the experiment I six rumen-cannulated Nellore steers (407 ± 24 kg BW) were used in a 6 x 6 Latin square design experiment. Were evaluated 5 levels of inclusion of WC (0, 8, 16, 24 and 32% DM basis) in diets containing 87% concentrate (treatments WC0, WC 8, WC16, WC24 and WC32 respectively). Also, it was evaluated a diet containing the same amount of total fat content of WC32 but with no WC and using soybean oil (SO treatment). Increasing WC levels linearly decreased DM and OM intake (P < 0.01). CP and NDF intakes were not affected by the treatments. Total fat digestibility linearly increased due the WC increase in the diets (P < 0.001). Total DM (P = 0.019) and OM (P = 0.020) digestibilities linearly decreased with increasing levels of WC. SO inclusion did not affect DM (P = 0.462) and OM (P = 0,469) digestibilities compared with CA0 and there was no effect of fat source over DM (P = 0.124) and OM (P = 0.110) digestibilities. Rumination time linearly increased due the WC inclusion (P = 0,002). Increasing WC levels quadratically increased ruminal pH (P < 0.05) but no effect was observed with the SO addiction in the diet (P = 0.329) compared with CA0. Total VFA was linearly decreased with increasing levels of WC (P < 0.001). Increasing levels of WC linearly decreased the microbial protein synthesis (P = 0.011). In the experiment II a total of 280 Nellore bulls (initial BW = 349 ± 33 kg) were allotted in 40 pens. The statistical design was randomized incomplete blocks. The maximum final BW was obtained with 7.6% of inclusion of WC. Increasing levels of WC decreased DMI (P < 0.001). Adding SO also decreased DMI (P < 0.05) compared with WC0. Increasing the inclusion rate of WC quadractically increased the ADG, G:F, HCW, dressing percent, LM area and 12-rib fat (P < 0.05). The maximum ADG were obtained with 8% of inclusion of WC. On the other hand, the maximum G:F was obtained with 14.5% of WC. Compared with WC0, the SO inclusion did not affect carcass characteristics (P > 0.05). The inclusion of WC quadractically affect meat composition (P < 0.05). Compared with CA32, the inclusion of SO in the diet did not affect the meat composition. Increasing WC in the diets quadratically decrease (P = 0.035) lipid oxidation. No effects were observed in the sensorial evaluation flavor, taste and overall acceptability by the costumers (P > 0.05). Training sensory panelists also did not find differences between the treatments for flavor and taste. Increasing WC linearly decreased the tenderness (P = 0.045). Compared with CA32, the inclusion of SO increased meat tenderness (P = 0.031). In the experiment III was evaluated the ruminal fermentation kinetics of corn and cottonseed through the in vitro gas production technique. Five bottles for each energy source (corn and cottonseed), plus five additional bottles containing buffered medium and rumen fluid inoculum only (blanks) were used. The volume of gas produced was recorded at 0, 2, 4, 6, 8, 10, 12, 15, 19, 24, 30, 36, 48, 72 e 96 h of incubation using the pressure reading technique. Gas values were corrected for blank incubations. The corn had greater gas production than cottonseed (P < 0.001). Lag time was not different between the two energy sources (P = 0.646). Cottonseed had higher FDR than corn (P = 0.001) and shorter time to half asymptote (P < 0.001). Corn had higher potential of degradation compared with cottonseed observed by the higher gas production. Moreover, even with lower potential of degradation, the cottonseed fibrous fraction had a high degradability compared to corn

Der volle Inhalt der QuelleINTRODUCTION Maillard reaction products and lipid peroxidation, such as dicarbonyl compounds easily react with amino groups of proteins and nucleic acids leading to biological changes that can result in complications in diseases such as diabetes, atherosclerosis and neurodegenerative. The consumption of Maillard Reaction Products (MRP) has increased in recent decades and there is evidence that these substances are absorbed and can participate in pathological processes, although there is no consensus about the possible harmful health effects from their intake. We highlight the need to identify the consumption of MRP, mainly in vulnerable populations like children and diabetics, in order to establish acceptable daily intakes and guidelines for the food industry. OBJECTIVES: a) validate the methodology to measure indicators of the Maillard reaction: hydroxymethylfurfural (HMF), Furosine (RUF) carboxymethylysine (CML) and fluorescent intermediate compounds (FIC) in breakfast cereals (corn flakes and granola) and coffee, b) to evaluate if there are differences in the levels of these compounds contents among brands commercialized in São Paulo METHODS: two lots of 3 brands of flakes cereal, 3 brands of granola and 5 coffee brands present in 100 per cent of supermarkets visited in the city Sao Paulo were analyzed. HPLC methodology validation was assessed by determining accuracy (recovery), repeatability, and sensibility (linearity, limits of detection and quantitation) for the compounds: HMF and FUR. The contents of the Fluorescent Intermediary compounds (FIC) was measured by spectrophotometric method and the levels of CML by ELISA. RESULTS: Calibration curves determination coefficient (r 2) were higher than 0,99 for all compounds. Recovery ranged from 84 to 110 per cent and repeatability average was 3,5 per cent. The average content of free and total FIC was higher for coffee 232CIF/mg and 765CIF/mg respectively. The brands of granola and flakes was similar but just brands F1 and F2 was similar between brands (p<0,05). For HMF the higher values were for granola 67,5mg/kg. The presence of dried fruit in these grains may 11 have contributed significantly to the higher rate of this indicator. For indicator FUR average was higher in granola samples (301mg/100g of protein) and it was not possible to quantify the levels of FUR for coffee. All brands analyzed for HMF and FUR was similar (p<0,05). CML average was higher for coffee (1823,5ng/mg of protein). The brands analyzed was similar for all samples (p <0.05). CONCLUSIONS: Flakes contribute to higher intake of MRPs from early stage of the Maillard reaction (MR), the granola contributes to higher intake of MRPs from intermediate phase of MR and coffee contributes significantly to higher intake of final MRPs. Data suggest that coffee has more severe thermal treatment causing a higher concentration of MRPs from the final phase of the MR

Der volle Inhalt der QuelleEndophytic fungi are present in plants in various environments and produce compounds with wide chemical properties and applications, both in the medical and in agronomic field. However, much remains to be investigated about their biotechnological potential, especially in unexplored places. Islands have a particular and highly vulnerable environment, making them promising sites in search of unusual or endemic organisms. Thus, this work represents the isolation and chemical and biological study of endophytic fungi isolated from 2 species of plants of the genus Anthurium of Alcatrazes island-SP. For this, leaf fragments from plants A. loefgrenii (HRCB 46467) and A. alcatrazense (HRCB 46465 - endemic plant from the Island) were inoculated onto 10 culture media with different composition, resulting in the isolation of 106 endophytic fungi. Three strains were selected to be studied through chemical analysis by MALDI-TOF-MS and bioassay against phytopathogens. These were identified by morphological and molecular techniques as Penicillium citrinum (P2MSF2F3), Penicillium simplicissimum (P210-4F2) and Aureobasidium melanogenum (P7AF2F3). In the study of secondary metabolites of P. citrinum it was isolated the compound citrinin, which showed inibitory activity against the plant pathogens Colletotrichum gloeosporioides (MIC= 125 μg mL-1), Colletotrichum lindemuthianum (MIC= 0.48 μg mL-1), Phomopsis sojae (MIC= 250 μg mL-1) and Fusarium oxysporum f. sp. phaseoli (MIC= 125 μg mL-1). Other fraction obtained from the metabolic extract of P. citrinum (F3a3 fraction and citrinin), showed inibitory activity (100% inibition) to Leishmania infantum promastigotes. In the study of secondary metabolites of P. simplicissimum it was obtained F2b fraction, active against L. infantum (100% inhibition), which were isolated andrastin A and penicisoquinoline compounds, the first report of its production for this species, as well 5 unidentified compounds. In the study of secondary metabolites from A. melanogenum was isolated the methyl-orsellinate compound, first reported for this fungus. From the same strain was obtained F1d2l fraction, active against L. infantum (100% inhibition), from which were isolated 2 unidentified compounds. This is the first report of fungi isolated from Alcatrazes Island anthuriums and the study of their secondary metabolites. This study presents contribution to knowledge of endophytic fungi and their metabolic potential with applications in the medical and agronomic fields.

Der volle Inhalt der QuelleThe aim of this study was evaluate the different effects of adding wheat fiber to replace meat and fat on technological characteristics of sensory acceptance and hunger satisfaction in beef burger. At first, the aim was to develop burgers with different effects of adding oat bran to replace partial and total of fat, however, the results regarding the sensory acceptance were very negative. Because of this, the proposal was modified to include different levels of adding wheat fiber to replace the meat and fat. Five different treatments were processed: hamburger with 77,6% of beef, 19,4% of fat, 0% wheat fiber and water (Control), hamburger with 68,9% of beef, 17,2% of pork fat, 1,6% of wheat fiber and 9,4% of water (1,5% Fiber), hamburger with 60,1% of beef, 15,0% of pork fat, 3,1% of wheat fiber and 18,8% of water (3% Fiber), hamburger with 51,4% of beef, 12,8% of pork fat, 4,7% of wheat fiber and 28,1% of water (4,5% Fiber) and hamburger with 42,6% of beef, 10,7% of pork fat, 6,3% of wheat fiber and 37,5% of water (6% Fiber). Protein concentrations, fat, moisture, ash, pH, texture, color, loss after cooking and reduction in diameter were determined. For sensory evaluation a hedonic scale of nine points was used, with 103 consumers who evaluated the flavor, texture, juiciness and overall acceptance parameters. Satiety analysis was performed with 34 evaluators who noted down on a visual analog scale how much they were feeling hungry before and every hour after consumption, up to 3 hours. The results were submitted to ANOVA and Tukey\'s test at 5% level. In physical-chemical and centesimal analysis, the higher the addition of low wheat fiber protein, the lower the protein and lipid content. The moisture was higher when the content of meat/fat was reduced and the wheat fiber increased in the burger. In the analyzes of ash, pH and losses after cooking there was no significant difference (p>0,05). In diameter reduction, the higher the reduction of meat/fat ratio and the higher the wheat fiber addition, the lower the hamburger diameter was. In texture analysis, there was a negative correlation between addition of wheat fiber and hardness. For elasticity, the Control Fiber sample differed significantly (p<0,05) from samples 4,5% Fiber and 6% Fiber. For chewability, the greater the amount of meat/fat and the lower the amount of wheat fiber, the higher the required energy to chew food. And for cohesiveness, there was no significant difference (p>0,05). In color analysis, no significant difference (p>0,05) in the attributes a* and b* but in the L* attribute all samples differed significantly (p<0,05) from Control. In the sensory analysis, the Control, 1,5% Fiber, 3% Fiber and 4,5% Fiber samples obtained the highest values between 6,64 and 7,63 and the 6% Fiber sample got the lowest values between 5,82 and 6,91. In satiety analysis, a reduction in the feeling of hunger had been found right after the hamburger consumption, a hunger increase over a period of three hours, and at the end the feeling of hunger returned to the initial level. Thus, wheat fiber can be used as a substitute for meat/fat beef burger only until the level of 3% Fiber.

A leflunomida (LF) é um pró-fármaco antireumático pertencente ao grupo de fármacos modificadores do curso da doença, sendo empregada no tratamento da artrite reumatóide. Encontram-se disponíveis no mercado e medicamentos referência ARAVA produzido pela empresa Sanofi Aventis e as versões genéricas fabricadas pelas indústrias farmacêuticas Aché, Biosintética, Cristália, Marinha do Brasil e Zodiac. Para registro de um produto farmacêutico no Brasil, deve-se seguir as exigências da Agência Nacional de Vigilância Sanitária, que requer, dentre vários documentos, o estudo de estabilidade do medicamento e questão. Este estudo deve incluir diversos testes, sendo que a determinação do teor do fármaco e suas substâncias relacionadas são fundamentais para se compreender e determinar o prazo de validade de um produto. O objetivo deste trabalho foi desenvolver e validar uma metodologia analítica de teor e substâncias que permitisse avaliar a estabilidade dos comprimidos de L.F. Foram realizados estudos de degradação forçada no insumo farmacêutico ativo e no protótipo de comprimidos de L.F. proposto pela Fundação Ezequiel Dias (FUNED), empregando a hidrólise ácida, hidrólise alcalina, oxidação, degradação térmica e fotolítica. As amostras degradadas deram subsídio para o desenvolvimento e validação de um método, por cromatografia a líquido de alta eficiência, para determinação do teor e suas substâncias relacionadas. Uma coluna C18 (125x4,0mm, 5µm, a 25° graus Celcius), uma fase móvel em eluição, gradiente de acetato de amônio 10mM:acetonitrila (0 min-70:30; 15min-20:80; 16min-70:30 e 20 min-70:30) e um detector no ultravioleta (261nm) foram empregados para se atingir uma resolução adequada na separação da L.F. e suas substâncias relacionadas. Foram realizados os testes de degradação forçada, sendo que a hidrólise básica gerou apenas um produto de degradação (r=0,33), enquanto a ácida proporcionou o surgimento de dois(r=0,33 e 0,77); onze substâncias surgiram após a oxidação (r=0,16; 0,21; 0,41; 0,48; 0,58; 0,64; 0,67; 0,73; 0,78; 0,82 e 0,86). O método em eluição gradiente foi então validado de acordo com as diretrizes da RE n° 899 de 05/2003 da ANVISA e do DOQ-CGCRE-008 do INMETRO. A linearidade, na faixa de 10-60 µg/mL, foi demonstrada utilizando ANOVA (Fcalculado < Fcrítico). Comprovou-se as precisões intra-corrida (DPR≤3,3%) e intra-corrida (DPR≤5,0%) nas concentrações de 20; 40 e 60 µg/mL aplicando ANOVA. A exatidão variou de 98, 30% a 102,36% e a robustez foi satisfatória em todas as condições avaliadas. Aestabilidade dos comprimidos de LF, nas embalagens blíster de cloreto de polivinilideno e frasco de polietileno, foi então avaliada utilizando o método validado, sendo que em ambas foram quantificados os produtos da hidrólise alcalina (r=0,33) e da hidrólise ácida (r=0,77). Os resultados do estudo de estabilidade da formulação foram insatisfatórios para a LF devido à queda no seu teor superior a 5% no estudo acelerado e de longa duração em ambas embalagens. Pode-se concluir que o método indicativo de estabilidade foi desenvolvido e validado com sucesso para a quantificação do teor e substâncias relacionadas. Portanto, este método pode ser empregado na indústria farmacêutica tanto para o controle de qualidade quanto para avaliação dos estudos de estabilidade de comprimidos de LF.
Leflunomide (LF) is a prodrug of the disease-modifying antirheumatic drug (DMARD) used in rheumatoid arthritis. It is commercially available in tablet presentations of 10, 20 and 100 mg. The reference drug ARAVA reference manufactured by Sanofi Aventis and generic versions manufactured by pharmaceutical companies Aché, Biosintética, Cristália, Brazil's Navy and Zodiac are available in the market. For registration of a pharmaceutical product in Brazil it must follow the requirements of Agência Nacional de Vigilância Sanitária, which demands, among many documents, the stability study of the product concerned. This study should include several tests, and the determination of drug content and its related substances are fundamental to determine the shelf life of a product. The aim of this study was to develop and validate an assay and related substances analytical methodology that allow to evaluating the stability of the LF tablets. Forced degradation were perfomed on active pharmaceutical ingredient and LF tablets prototype proposed by FUNED, employing acid hydrolysis, alkaline hydrolysis, oxidation, photolytic and thermal degradation. The degraded samples allowed the development and validation of a liquid chromatography high efficiency method to determine the drug and its related substances. A C18 column (125x4,0mm, 5μm, 25 ° Celcius), a gradiente mobile phase of 10mM ammonium acetate: acetonitrile (0 min-70: 30; 15 min, 20: 80; 16min-70: 30 and 20 min-70: 30), and a ultraviolet detector (261nm) were used to achieve adequate resolution in the separation of LF and its related substances. Forced degradation test waere performed, which generated only one basic hydrolysis degradation product (r = 0.33), while the acidic gave the rise of two (r = 0.33 and 0.77); eleven substances arose after oxidation (r = 0.16; 0.21; 0.41; 0.48; 0.58; 0.64; 0.67; 0.73; 0.78; 0.82 and 0 , 86). The gradient method was then validated accordance to ANVISA RE No. 899 05/2003 and INMETRO DOQ-CGCRE-008 guidelines. The linearity in the range of 10-60 mg / mL was demonstrated using ANOVA (Fcalculado

Resumo: Atualmente os consumidores estão cada vez mais interessados no consumo de alimentos com apelos para a promoção da saúde. No desenvolvimento de produtos cárneos com características funcionais, os cereais, os quais possuem uma grande proporção de fibra insolúvel, têm vantagens fisiológicas e tecnológicas por serem constituídos principalmente de celulose. Destacam-se a capacidade de ligação de água e gordura e também a capacidade de reduzir custos de formulação. Sob este aspecto, este trabalho teve o objetivo de estudar e desenvolver formulações de produtos cárneos reestruturados empanados com alto teor de grão inteiro, farinhas, farelos e flocos de cereais integrais garantindo suas características tecnológicas e sensoriais. Primeiramente, foi realizada a seleção e avaliação das propriedades tecnológicas de diferentes cereais para combiná-los na forma de blends de cereais, através de analise físicoquímica e sensorial. A seguir, foi realizado o estudo do efeito da adição de diferentes blend de cereais (6% a 24%) em produto cárneo reestruturado empanado com avaliação das propriedades tecnológicas através da metodologia de superfície de resposta. Foram estudadas como variáveis respostas: umidade, absorção de óleo, textura, cor, bem como a qualidade sensorial geral e os atributos de aparência, cor interna e externa, textura e em especial crocância e sabor. Finalmente, foi estudada a influência dos métodos de cocção (fritura em óleo, forno convencional e forno microondas) sobre empanados de frango adicionados de sete tipos de cereais integrais. A seleção dos cereais e elaboração dos blends com sete tipos de cereais resultaram em teores adequados de proteínas (14,52%), lipídeos (10,39%) e carboidratos (62,72%) e um bom índice de capacidade de retenção de água (4,8). Nos produtos empanados a menor absorção de óleo foi para a formulação com 15% blends. A adição de até 24% de cereais integrais resultou num bom desempenho de textura e cor objetiva para os produtos empanados fritos. Em produtos empanados pré-fritos, houve um aumento na intensidade da cor amarela devido à adição dos blends de grãos e farinhas. Do ponto de vista sensorial os empanados adicionados de sete tipos de cereais integrais apresentar 97% de aceitação e 91% de intenção de compra pelo painel de consumidores, não diferindo da formulação controle. Os produtos submetidos ao forno microondas com 0% e 15% de cereais integrais, obtiveram os maiores porcentuais de umidade e lipídeos em comparação aos produtos cozidos em forno convencional, maior luminosidade e menor intensidade de vermelho, menor força de cisalhamento e as menores notas atribuídas pelos provadores em todos os atributos sensoriais, caracterizando um produto úmido, flácido, claro e sem crocância. Este trabalho permitiu a elaboração de um produto cárneo reestruturado empanado com alto teor de cereais integrais com boa aceitação sensorial, sendo necessários mais estudos para otimizar a substituição do processo de fritura por forneamento ou cocção em microondas
Abstract: Currently consumers are increasingly interested in food consumption with appeals for the promotion of health. In the development of meat products with functional features, cereals, which have a high proportion of insoluble fiber, have physiological and technological advantages because they are made primarily of cellulose. In this respect, this work was to study and develop formulations restructured breaded meat product with high content of whole grain, flour, bran and flakes, cereals and ensuring their sensory acceptance and technological. First, we performed the selection and evaluation of technological properties of different cereals and combine them in the form of blends of cereals, through physicalchemical analysis and sensory acceptance. Next, we performed a study of the effect of adding different blend of cereals (6% to 24%) in restructured breaded meat product and technological properties evaluation by response surface methodology. Were studied as variables response: moisture, oil absorption, texture, color sensory acceptance and appearance attributes, external and internal color, texture, flavor and crispness. Finally, we studied the influence of cooking methods (frying in oil, conventional oven and microwave oven) on breaded chicken added seven types of grains. The selection of grains and the blends with seven types of grain resulted in adequate levels of protein (14.52%), lipid (10.39%) and carbohydrate (62.72%) and a good index of holding capacity water (4.8). Breaded products the oil absorption was lower for the formulation with 15% blends. The addition of up to 24% of grains resulted in a good performance color and texture to the breaded products fried. In breaded pre-fried products, an increase in color saturation due to the addition of the blends of grains and flours. From the standpoint of the sensory the breaded products added seven types of grains presented 97% acceptance and 91% of purchase intention by the consumer panel did not differ from the control formulation. The products subject to the microwave oven at 0% and 15% whole grains, had the highest percentage of moisture and lipids in comparison to products cooked in conventional oven, greater brightness and low saturation yellow, lower shear force and lower scores by the judges in all sensory attributes, configuring in a product moist, flabby, clear and without crunchiness. This work allowed the preparation of a breaded restructured meat product with high content of whole grains with good sensory acceptance, more research is needed to optimize the replacement of the frying in the baking or microwave oven

Der volle Inhalt der QuelleStaphylococcus pseudintermedius is an opportunistic pathogenic bacterium responsible for most skin and post-surgical infections in dogs. The number of bacterial strains resistant to β-lactam antibiotics is increasing and are the major challenges now faced by veterinary medicine. Bacteria that produce biofilm are more resistant to treatment and thus, the production of this structure is already considered a virulence factor. In a biofilm, bacteria are embedded in a matrix of extracellular polymeric substances (EPS) some of which are proteins. With the objective to know more of this array element, the characterization of the biofilm matrix proteome (BMP) from a highly virulent S. pseudintermedius strain isolated from a dog with severe pyoderma was performed. Biofilm was developed by culturing the S. pseudintermedius strain 5819/10 in specific media. The biofilm matrix was then be separated from bacterial cells and evaluated for their protein content and complexity. Finally, the proteome was separated by 1D electrophoresis and characterized by nanoLC-ESI-Q-TOF and analysed using bioinformatics tools. The BMP of strain S. pseudintermedius 5819/10 consisted in a diverse group of proteins, where 63% of the proteins could be related to either the extracellular region or the plasma membrane, as protein complexes, and most of them had functions essential to cell survival. However, it was not possible to establish a clear relation between them and biofilm formation. Proteins known to be involved in biofilm formation consisted mostly of regulator factors of biofilm formation as well as virulence factors of-mainly-bacterial cell adhesion and host colonization. The prevalence of adhesins and the almost total absence of proteins involved in EPS synthesis pointed to a biofilm matrix where cells are directly or indirectly closely glued together to each other.
Staphylococcus pseudintermedius (S.pseudintermedius) é uma bactéria patogénica oportunista, responsável pela maioria das infeções cutâneas e pós-cirúrgicas em cães. O número de estirpes resistentes a antibióticos β-lactâmicos está a aumentar constituindo actualmente um dos grandes desafios enfrentados pela medicina veterinária. As bactérias mais resistentes ao tratamento são aquelas que produzem biofilme sendo esta capacidade considerada um fator de virulência. Num biofilme, as bactérias estão envoltas numa matriz de substâncias poliméricas extracelulares (SPE), algumas das quais são proteínas. Tendo por objectivo obter mais informação acerca do biofilme, foi caracterizado o proteoma da matriz do biofilme de uma estirpe bastante virulenta de S. pseudintermedius isolada de um cão com piodermite profunda. Para tal cultivaram-se biofilmes da estirpe de S. pseudintermedius 5819/10 em meio apropriado, separou-se a matriz das suas células bacterianas e avaliou-se as proteínas presentes quanto ao seu conteúdo e complexidade. Posteriormente o proteoma foi separado por electroforese 1D, caracterizado por nanoLC-ESI-Q-TOF e analisado usando ferramentas bioinformáticas Constatou-se que o proteoma da matriz do biofilme da estirpe 5819/10 de S. pseudintermedius é muito diverso e que 63% das proteinas podem estar relacionadas com a região extracelular do biofilme ou da membrana plasmática na forma de complexos proteicos. Verificou-se também que a maioria das proteínas identificadas possui funções essenciais para a sobrevivência da bactéria mas não foi possível estabelecer uma relação clara entre elas e a formação de biofilmes. Algumas proteínas que se sabe estarem envolvidas na formação de biofilmes foram identificadas, tratam-se principalmente de factores reguladores da formação de biofilme e outros factores de virulência relacionados com a colonização de um hospedeiro a adesão bacteriana a uma superfície. A prevalência de adesinas e a ausência quase total de proteínas envolvidas na síntese de SPEs, forneceu dados que apoiam a hipótese que a matriz do biofilme do S. pseudintermedius 5819/10 seja constituída por células directamente ou indirectamente unidas entre si.

Resumo: A redução do consumo de sódio tem sido recomendado por vários órgãos da saúde em função da correlação positiva entre ingestão de sódio e o desenvolvimento de doenças como a hipertensão arterial, cardiovasculares e renais. Produtos cárneos emulsionados cozidos, principalmente salsichas, estão entre os mais consumidos no Brasil e apresentam elevados teores de sódio. Em algumas categorias de salsichas, matérias-primas menos nobres são adicionadas para reduzir o custo, dentre elas a carne mecanicamente separada de aves (CMS) permitidas em concentrações de até 60%. Cloreto de sódio é um ingrediente multifuncional, pois confere propriedades sensoriais, conservantes e tecnológicas em produtos cárneos. Adicionalmente, em formulações contendo alto teor de CMS sua redução pode ser ainda mais desafiadora pela perda de propriedades funcionais da matriz cárnea (presença de proteínas de menor funcionalidade, porções da medula óssea, alto teor de colágeno e gordura). Desta forma, este trabalho teve como objetivos estudar a influência da redução de sódio na qualidade de salsichas com alto teor de CMS. O trabalho foi dividido em três etapas. Na primeira etapa, blends de cloreto de potássio e cálcio, com força iônica equivalente a 2% NaCl, foram utilizados para substituir 25% ou 50% do NaCl em salsichas contendo 60% de CMS. O objetivo desta etapa foi avaliar o efeito da adição dos blends de sais sobre as propriedades físico-químicas e sensoriais das salsichas. Foram determinados: teor de sódio, Aw, estabilidade de emulsão (batter), avaliação de cor instrumental, perfil de textura, microestrutura e teste de aceitação sensorial. Na segunda etapa, uma formulação contendo blend de sais para substituir 50% NaCl foi selecionada com base nos dados da primeira etapa.e adicionada de derivados de alho (fresco, em pó, óleo comercial e extrato obtido via líquido pressurizado). O objetivo foi investigar os efeitos dos derivados de alho como antioxidantes e antimicrobianos nas formulações de salsichas. As determinações realizadas foram a mesmas da primeira etapa, com exceção da microestrutura e acrescidas da quantificação de Substâncias Reativas ao Ácido Tiobarbitúrico e análises microbiológicas durante 60 dias sob refrigeração. Finalmente, para as mesmas formulações de salsichas, uma terceira etapa foi realizada para avaliar o efeito dos derivados de alho como realçadores de sabor por meio da Análise Descritiva Quantitativa e Teste de Aceitação, utilizando-se duas amostras comerciais para efeito comparativo. Alho fresco e extrato de alho PLE, nas concentrações de 1% e 0,02% respectivamente, apresentaram propriedades antioxidantes e antimicrobianas durante a vida útil das salsichas. Dezoito descritores caracterizaram as amostras das salsichas avaliadas pelos assessores na análise descritiva quantitativa. De forma geral, os tratamentos do estudo apresentaram maior intensidade de sabor e aroma de alho e as amostras comerciais apresentaram aroma e sabor defumado. No teste de preferência, as salsichas comerciais foram as mais aceitas para impressão global, no entanto, salsichas elaboradas para o estudo apresentaram muitas similiaridades entre si em seus perfis sensoriais. Assim, a adição de derivados de alho em salsichas com alto teor de carne mecanicamente separada e adicionada de blends de sais substitutos de NaCl mostraram ser uma alternativa promissora neste seguimento
Abstract: The positive correlation between salt intake and the development of diseases including hypertension, and cardiovascular and renal disorders has led health authorities to recommend the reduction of sodium intake. Cooked emulsified meat products, mainly sausages, have high sodium levels and are among the most consumed products in Brazil. In some types of sausages, the mechanically deboned poultry meat (MDPM) stands out as less noble materials used to reduce costs, allowed in concentrations of up to 60%. Sodium chloride is a multi-functional ingredient, since it provides sensory, preservative, and technological properties in meat products. Sodium reduction can be even more challenging in formulations containing high MDPM levels, due to loss of functional properties of the meat matrix (presence of proteins of lower functionality, portions of the bone marrow, high collagen and fat contents). Thus, this study aimed to investigate the effect of sodium reduction on the quality of sausages with high MDPM content. The study was divided into three stages. In the first step, blends of potassium chloride and calcium chloride with ionic strength equivalent to 2% NaCl were used to replace 25% or 50% of NaCl in sausages containing 60% MDPM. The purpose of this step was to evaluate the effect of the addition of salt blends on the physicochemical and sensory characteristics of the sausages. The following parameters were investigated: sodium content, Aw, emulsion stability (batter), instrumental color, texture profile, microstructure, and sensory acceptance. In the second step, a formulation containing a salt blend to replace 50% NaCl was selected from the first step, and garlic derivatives (fresh, powder, commercial oil, extract obtained by pressurized liquid extraction) were added. The objective was to investigate the effects of garlic derivatives as antioxidant and antimicrobial agents in the sausage formulations. The determinations were the same as the first step, except for microstructure, plus measurement of Thiobarbituric Acid Reactive Substances and microbiological analyses during 60 days of refrigerated storage. Finally, a third step was carried out to evaluate the effect of garlic derivatives as flavor enhancers through quantitative descriptive analysis and acceptance tests, using two commercial samples for comparison. Fresh garlic and garlic PLE extract at concentrations of 1% and 0.02%, respectively, presented antioxidant and antimicrobial properties throughout the shelf life of the sausages. The sausage samples were characterized by eighteen descriptors selected by the assessors in the quantitative descriptive analysis. In general, the treatments had higher flavor intensity and garlic flavor, while the commercial samples exhibited smoky aroma and flavor. In the preference test, the commercial sausages were the most accepted for overall impression, and the sausages prepared for the study presented very similar sensory profiles. Thus, the addition of garlic derivatives in sausage formulations containing high mechanically separated poultry and blends of salt substitutes proved to be a promising alternative in this field

Der volle Inhalt der QuelleMass spectrometry, coupled or not with other techniques, is very useful for the determination of new compounds, transformation/degradation products, metabolites and quantification at trace levels in many different matrices, due to the versatility of such a technique, specially regarding to analysis modes. In the present work a methodology was systematized for the application of mass spectrometry techniques in order to identify metabolites and transformation/degradation products for human and veterinary drugs usage. Computational chemistry tools were used to assist in the elucidation of the structure of the compounds formed during the process. The methodology was employed for identification and quantification of rosuvastatin transformation/degradation products generated during the heterogeneous photocatalysis process with ZnO, for the identification of sulfamethoxazole, ciprofloxacin and norfloxacion transformation/degradation products generated during the photolysis in aqueous medium and for quantifying amoxicillin transferred to bovine milk. The feasibility of identification of amoxicillin metabolites present in bovine milk using the same sample preparation procedure exploited for the quantification analysis was also assessed. Ten main transformation/degradation products of rosuvastatin photocatalysis were identified, as well as ten main transformation/degradation products of sulfamethoxaxole photolysis in aqueous medium, fifteen main transformation/degradation products of ciprofloxacin photolysis in aqueous medium and fifteen main transformation/degradation products of norfloxacin photolysis in aqueous medium. The methodology applied for the bovine milk amoxicillin quantification was demonstrated to be adequate, but additional studies are needed to identify amoxicillin metabolites in the milk matrix. The results of ab initio calculations utilised for the study of rosuvastatin and sulfamethoxazole transformation/degradation products show that this technique can be very useful for the structural elucidation of chemical compounds which are formed.

Der volle Inhalt der QuelleWe study the structure of the tori equipped with the Rieffel's star product. In particular we determine their spectrum, their center and the type of their factorial representations. This product is like the Moyal product, but the Neumann unicity of representation of commutation relations which says that the regular representation generates a type one factor, is no more true in the case of the tori. Next, we apply the same construction to space of functions on abelian connected groups. We obtain type one-infinity, two-one and two-infinty factors. Then, we try to construct a convergent and tangential deformation quantization on the dual of a nilpotent Lie algebra. Such a construction is realized here in the case of a nilpotent special Lie alegbra, using a deformed version of the formulae of Rieffel. More precisely, we consider a product of exponential, instead of the usual exponential mapping to identify the Lie group with the Lie algebra. Finally we define the adapted Fourier transform and we related it to unitary representations of the corresponding Lie group

This dissertation investigates causal factors that lead to implementing a top-down approach to platform product design as well as performance outcomes from such a design. A top-down approach to platform product design requires intentional planning of a new platform-based product design during the new product development process, incorporating a level of modularity into the new design, and planning derivative products based on common subsystems and interfaces. A thorough review of literature was used to build a theory of platform product design founded on risks and benefits. Benefits are that platform design can drive revenue, introduce cost and time efficiencies, lead to more reliable products and offer managerial benefits in the form of adjacencies. Risks include increased costs and time to market for the first product, reduced revenue due to commonality, sub-optimal product design, and increased management complexity during the NPD process. A conceptual model was then developed encompassing antecedents, contributing factors, and market performance measures to implementing a top-down approach to new platform product design. The model was empirically tested in the context of U.S. manufacturing firms using data collected from 249 manufacturing product design managers. Respondents included managers from B2B firms and B2C firms as well as small and large firms. In order to test the model, a new continuous multidimensional measurement scale of top-down platform product design was developed. Results showed that market turbulence, technological turbulence, a product that is new to the market and competitive strategies of differentiation and design for supportability are positively related to platform design. Firm type - B2B versus B2C - and firm size - large firms versus small firms - was found to moderate this relationship. Regarding firm type, products that are new to the market are positively related to platform design for B2C firms, not B2B firms, while a competitive strategy of design for supportability is positively related to platform design for B2B firms, not B2C firms. Regarding firm size, a competitive strategy of design for supportability is positively related to platform design for large firms, not small firms. These findings suggest that an important predictor of top-down platform design is risk or uncertainty. Results also showed that top-down platform product design is positively related to both short term and long term market performance although this relationship is significantly greater for long term market performance. In the short-term, performance as measured by sales and market share was greater than performance as measured by profits. In the long-term, performance measured by sales and profits was greater than performance measured by market share. Organizational support in the form of management buy-in and cross-functional integration partially mediates the relationship between platform design and long term market performance. Finally, strategic flexibility was found to have an inverse relationship with top-down platform down. Firms lacking strategic flexibility were more likely to pursue a top-down platform design. This is in line with findings that suggest top-down platform design is undertaken when uncertainty is high and strategic flexibility is an advantage These findings contradict conventional wisdom in new product development literature and offer a better understanding of why platform design is important in a way that has not been previously defined.

Resumo: A busca por alimentos com melhores propriedades nutricionais tem levado osegmentode processamento de produtos cárneos a rever suas formulações em relação a alguns componentes que podem aumentar o risco de doenças crônicas, tais como teores de gordura, sal, aditivos, entre outros. No entanto, a reformulação destes produtos deve manter as características de segurança, estabilidade, sabor e demais atributos característicos do produto. As carnes constituem-se em importante fonte de nutrientes importantes, como ácidos graxos, minerais, proteínas e peptídeos bioativos na dieta. Porém, produtos cárneos apresentam grande percentual de gordura saturada e colesterol além do elevado teor de sódio. Neste contexto, o objetivo do estudo foi substituir em 50% o percentual de gordura em produto fermentado cozido (pepperoni) por diferentes níveis de fibra prebiótica (3, 6 e 9% de frutooligossacarídeo ¿ FOS) e avaliar a qualidade global durante 60 dias de armazenamento refrigerado. E substituir em 50 e 75% o teor de NaCl por KCl em pepperoni ao utilizar realçadores de sabor (0,06% glutamato monossódico, 0,06% 5¿ribonucleotídeos- inosinato dissódico e guanilato dissódico) e aminoácidos (1% lisina e 0,075% taurina) com avaliação físico-química, cor, perfil de textura e sensorial. Pepperonis com teor reduzido de gordura adicionado de diferentes níveis de FOS mantiveram as características físico-químicas, microbiológicas, cor, perfil de textura e sensoriais comparadas à formulação controle (sem redução de gordura). Além disso, o frutooligossacarídeo adicionado não foi degradado durante todo o período de vida útil dos produtos. Os pepperonis com redução de cloreto de sódio em 50% foram similares ao produto controle (sem redução de NaCl) em relação a todos os parâmetros avaliados e a redução de sódio foi de 42,80%. No entanto, a redução de 75% NaCl proporcionou alterações na cor e perfil de textura. A aceitação sensorial também foi prejudicada na maioria das formulações estudadas porém a combinação de glutamato monossódico com inosinato dissódico/guanilato dissódico, lisina e taurina resultou em formulações com notas semelhantes à formulação controle. Neste experimento, a redução de sódio foi de 68,10%. Deste modo, o estudo demonstra que a redução de gordura e cloreto e sódio em produto cárneo fermentado cozido é possível e traz benefícios à qualidade nutricional destes produtos
Abstract: The demand for food with improved nutritional properties has led the meat products industry to re-evaluate their formulations. However, the reformulation of these products must preserve the food safety, stability, taste and other functional properties. The meat will constitute an important source of nutrients such as fatty acids, minerals, proteins and bioactive peptides in the diet. On the other hand, meat products have a high content of saturated fat and cholesterol, besides the high sodium content and very low levels of fibers. In this context, the aim of this study was: replace 50% of the total fat in cooked fermented product (pepperoni) by different levels of prebiotic fibre (3, 6 and 9% of fructooligosaccharides - FOS) and to evaluate the overall quality during 60 days of in refrigerated storage. And to replace 50 and 75% of NaCl content by using KCl in the pepperoni using flavor enhancers (06% monosodium glutamate, 06% 5'ribonucleotídeos-inosinate disodium and guanylate disodium) and amino acids (1% lysine and 075% taurine) with physico-chemical evaluation, color, texture profile and sensory analysis compared to a control formulation (no fat reduction). Pepperoni with reduced fat supplemented with different levels of FOS maintain the physico-chemical and microbiological properaties, color, texture profile and sensory characteristics when compared to the control formulation (no fat reduction). Moreover, the fructooligosaccharides were not degraded during the whole store period of the products. Pepperonis with 50% sodium chloride reduction were similar to the control (no reduction of NaCl) for all evaluated parameters, and the sodium reduction was 42.80%. However, the reduction of 75% NaCl resulted in changes in color and texture profile. The sensorial acceptance was also impaired in most of the formulations of this study, although the combination of monosodium glutamate with disodium inosinate / disodium guanylate, lysine and taurine resulted in formulations with a similar score when compare to the control formulation. In this experiment, sodium reduction was 68.10%. Thus, the study demonstrates that reducing fat and sodium chloride in fermented cooked meat products is possible and can bring benefits in the nutritional quality of these products

This study aimed to carry out a survey of pollen types present in bee pollen and realize analyzes of their protein content and amino acid composition during different seasons. The experiment was conducted at the Sector of Apiculture, Faculty of Veterinary Medicine and Animal Science, Lageado Experimental Farm, UNESP, Botucatu. The pollen was collected weekly during the period of September 2012 and August 2013, from five hives, similar to the number of frames of brood and food through frontal collector pollen. The pollen from the collectors was mixed, weighed on an analytical balance, dried in an oven with forced ventilation, cleaned and acorns classified by grain size smaller and larger than 2.0 mm. Then the samples were stored in sterile vials which were kept under freezing for analyzes. The results were evaluated by ANOVA followed by Tukey's test to check for differences between means (P <0.05). It can be observed that the winter period (June, July, August) showed the largest total protein content (22.78% ± 3.1) and also significant differences when compared particle sizes greater than 2.0 mm and less than 2.0 mm (20.38 ± 2.6 ± 2.9% and 23.58%, respectively). No differences in the amino acid composition between the year seasons in bee pollen were found. Among the pollen types found stand out mainly Asteraceae, Poaceae and Myrtaceae, which were found in all seasons, proving that bees concentrated collection of resources according to the availability of plants in the seasons

A utilização de sais de nitrato e nitrito em produtos cárneos é secular e, com a evolução das técnicas de conservação alimentar, estes vêm sendo cada dia mais utilizados, pois melhoram o sabor e a cor. Os objetivos deste estudo foram realizar análises microbiológicas, de atividade de água, pH, concentração de nitritos e nitratos presentes em amostras de linguiças (tipo mistos e suínos) com Inspeção do Serviço Municipal e queijos (tipo colonial e prato), fiscalizados pelos Serviços de Inspeção Municipal e Estadual, produzidos na região do Vale do Taquari, Rio Grande do Sul. As amostras de queijos Prato (n=14) e Colonial (n=10) foram adquiridas diretamente nas indústrias com Inspeção Sanitária Municipal (n=11) e Estadual (n=13), produzidas em municípios do Vale Taquari durante os meses de abril, maio e junho de 2013. Para a coleta das amostras houve o cuidado de mantê-las íntegras, com o mínimo de contato ou manipulação. As amostras de linguiça foram coletadas em 11 estabelecimentos fiscalizados pelo Sistema de Inspeção Municipal (SIM). Os teores residuais de nitratos e nitritos, pH e atividade de água das amostras foram avaliados segundo as metodologias analíticas oficiais previstas na Instrução Normativa n° 20, de 21 de julho de 1999, do Ministério da Agricultura, Pecuária e Abastecimento (MAPA). As análises microbiológicas foram realizadas em laboratório certificado no Ministério da Agricultura (MAPA), na Rede Metrológica do Rio Grande do Sul, cadastrado na Fundação Estadual de Proteção Ambiental (FEPAM) e com ISO 17025. As concentrações de nitrato e nitrito encontradas acima do recomendado pela legislação nas amostras foram de 33,3% (p=0,030) e 100% (p<0,001), respectivamente. Em 41,7% (n=10) e 25% (n=6) do total das amostras de queijo foram encontrados índices de contaminação por coliformes termotolerantes e Staphylococcus coagulase positiva acima do preconizado pela legislação, respectivamente, contudo não foi verificada diferença significativa para os valores encontrados em relação ao valor de referência, e 100% das amostras de queijo estavam isentas de Salmonella spp. Em relação as linguiças, 30,3% das amostras apresentaram teor de nitrito e 69,7% apresentaram teor de nitrato acima do previsto pela legislação brasileira. As médias de atividade de água e do teor de nitrato apresentaram-se significativamente acima do valor de referência. Enquanto as médias de pH não demonstrou diferença significativa em relação ao valor de referência e a média de nitrito apresentou-se inferior a legislação, mas com elevado desvio padrão. Conclui-se que a totalidade das amostras de queijo analisadas neste estudo apresentou concentrações acima do recomendado pela legislação para nitrito e um terço apresentou-se não conforme em relação à concentração de nitrato. Sobre a linguiça, foi observada inadequação ao que é determinado pela legislação brasileira em relação à quantidade de nitrito e nitrato, parâmetros microbiológicos de coliformes termotolerantes, Staphylococcus coagulase positiva e Salmonella spp., atividade de água, e adequação em relação ao pH.
The use of nitrate and nitrite salts in meat products is centuries old and with the development of food preservation techniques they are being more used every day because it improves flavor and color. The objective of this study were to perform the microbiological analysis, and also analysis of water activity, pH, concentration of nitrites and nitrates in sausage samples (mixed type and pigs) with inspection of the Municipal Service, and cheese (colonial type and plate), supervised by Service Municipal and State Inspection, produced in the region of Vale do Taquari, Rio Grande do Sul. The sample of plate cheese (n=14) and colonial (n=10) were acquired directly in industries with Municipal Sanitary Inspection (n=11) and State (n=13), produced in municipalities in the Taquari Valley during the months of April, May and June 2013. The samples were collected with care to keep them intact and a minimal contact or manipulation. The sausage samples were collected from 11 establishments inspected by the Municipal Inspection System. The samples' residual levels of nitrates and nitrites, pH and water activity were evaluated according to the official analytical methods provided by the Normative Ruling No. 20 of July 21, 1999, of Ministry of Agriculture, Livestock and Supply. The microbiological analyzes were performed in laboratory certified by Ministry of Agriculture in the Metrology Network of Rio Grande do Sul, registered in the State Environmental Protection Foundation, with ISO 17025. The nitrate and nitrite concentrations found above the recommended by the legislation in the samples was 33.3% (p=0.030) and 100% (p <0.001), respectively. In 41.7% (n = 10) and 25% (n = 6) of the total samples of cheese contamination rates were found by thermotolerant coliform and Staphylococcus coagulase positive above recommended by law, respectively, but there was no significant difference to those found in relation to the reference value and 100% of cheese samples were free of Salmonella spp. In relation to the sausages, 30.3% of the samples had nitrite content and 69.7% had nitrate levels higher than expected by Brazilian law. The average of water activity and nitrate levels were significantly above the reference value. While the average of pH showed no significant difference from the reference value and the nitrite average has performed under law, but with high standard deviation. It is concluded that all the cheese samples analyzed in this study had higher concentrations than recommended by law for nitrite and a third it is not in accordance to the concentration of nitrate. Regarding the sausage, it was observed inadequacy in relation to what is required by Brazilian law in relation to the amount of nitrite and nitrate, microbiological parameters of thermotolerant coliform, Staphylococcus coagulase positive and Salmonella spp., water activity and suitability in relation to the pH.

Der volle Inhalt der QuelleBiocorrosion is the result of corrosion induced by micro-organisms and affects a wide range of economic activity sectors including oil & gas industry, nuclear industry, drinking water systems, and archeological materials. Fighting biocorrosion requires identifying and understanding the corrosion mechanisms. The aim of this work is the development of an analytical method based on Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) in order to discriminate the origin of metallic sulfides: abiotic (no living organisms involved in the corrosion mechanism) or biotic (living organisms involved in the corrosion reaction). Sulfate-Reducing Bacteria, SRB, are the bacteria leading to the biological formation of metallic sulfides, and thus involved in the biocorrosion mechanism. The approach taken is based on the fact that SRB produce reduced sulfur with a different sulfur isotopic ratio (34S/32S) than the natural isotopic distribution. In this work, standard metallic sulfides were prepared and analysed using XPS in order to obtain the surface composition, and thus using ToF-SIMS for having the isotopic composition of metallic sulfides. Finally, in this study, an analytical method using ToF-SIMS and a peak-fitting method using CasaXPS have been developed and validated. Moreover, different parameters which could influence the isotopic ratio value have been studied

Der volle Inhalt der QuelleThe generic affiliation of Fischerella and Hapalosiphon is problematic due to instability of morphological characters. The Fischerella and Hapalosiphon genera are differentiated by the presence of trichome multisseriate and uni or bisseriate, respectively. However, genetically these characters were not diacritical to distinguish genera. Molecular studies of strains isolated from Brazilian ecosystems are scarce for Fischerella and absent for Hapalosiphon. In this study, eight cyanobacterial strains, belonging to Hapalosiphonaceae family, isolated from Brazilian freshwater and soil were morphologically and genetically characterized and analyzed for bioactive compound productions. The morphological analyses identified five Fischerella (CENA19, CENA161, CENA212, CENA213, CENA214) and three Hapalosiphon (CENA63, CENA71, CENA72) morphotypes. The neighbor-Joining (NJ) and maximum likelihood (ML) phylogenetic analyses of 16S rRNA placed all isolated strains in high supported (99% NJ and ML of bootstrap) cluster containing members of the order Nostocales. Furthermore, the Fischerella strains studied were grouped in an internal clade with high bootstrap value (100% NJ and 86% ML), with exception of Fischerella CENA19. The position of this strain in the phylogenetic tree indicates that it needs taxonomical revision. The soil Hapalosiphon strains CENA71 and CENA72 also formed a separated tight internal clade (99% NJ and 98% ML), but the freshwater strain CENA63 was placed in a different clade (99% NJ and ML of bootstrap value) together with Hapalosiphon strains genera and Westielopsis prolifica SAG 16.93, originated from soil. The comparison of the phylogenetic analyses of individual regions of the genes 16S rRNA, rpoC1, rbcL, tufA, and cpcBA-IGS from the three Hapalosiphon strains and the two Fischerella strains CENA19 and CENA161 showed incongruent results due to different evolutionary rates of these genes. However, the concatenated phylogenetic analysis of these genes, showed that Fischerella CENA19 grouped with the two Hapalosiphon strains CENA71 and CENA72 with high bootstrap value (100%), while Fischerella CENA 161 and Hapalosiphon CENA63 were positionated each one in separate clades. The results indicate that the nomenclature of cyanobacterial strains from the family Hapalosiphonaceae needs revision. The intra and extracellular extracts of the Fischerella sp. strains CENA161 and CENA19 and Hapalosiphon sp. strains CENA71 and CENA72 showed inhibitory effects on the growth of pathogenic bacteria. The analysis in the mass spectrometer Q-TOF MS/MS indicated the presence of aeruginopeptin, cyanopeptolin, fischerellin, aeruginosin, oscillapeptilide, microcystins and tumonoic acid in the extracts. In the intracellular extracts of Fischerella sp. CENA161, three or four variants of microcystins, LR, LL, FR and/or M(O)R, were identified. Fragments of genes mcyA, mcyB, mcyC, mcyD, mcyE, mcyG and mcyI of this strain were sequenced. In both phylogenetic analyses performed with amino acid sequences of McyE and concatenated sequences of McyD, McyE and McyG, the microcystin synthetase enzymes were grouped according to the cyanobacterial genera, indicating a pattern of evolution

Der volle Inhalt der QuelleA program’s success is measured by the three parameters of cost, schedule and performance. This is true of any acquisition program, including instrumentation development and procurement. The primary purpose of Logistics is to influence and reduce the Total Ownership Costs (TOCs) to the Department of Defense while procuring a supportable system that meets the customer’s needs. The time to influence the TOCs is as early in the life-cycle of the program as can be done - where it is cheapest to affect a “fix.” This paper will briefly describe where Logistics influences ownership costs in the acquisition process. Examples of cost drivers identified in the Hardened Subminiature Telemetry Sensor System (HSTSS) program will be provided and the role of Integrated Product Team (IPT) members in influencing and reducing the TOCs will be discussed. This process is not just in the purview of the traditional logistician, but is also performed by each member of the program’s IPT. Each IPT member brings his unique knowledge and experiences to the teams pool of corporate knowledge. Examples will be provided of decisions made by the IPT that reduced TOCs.

Der volle Inhalt der QuelleThe increased poultry production and slaughtering encounters the responsibility of proper disposal of waste from slaughterhouses. Pressed further by legislation and environmental policies and the business opportunities were created industries processing animal by-products, known as "graxarias" which process these waste transforming them into high value-added flours used in feed composition. However, the wide variation in the composition of the raw materials and the lack of standardization of the manufacturing process are considered the major hallenges for the use of these foods as ingredients of rations. This study aimed to optimize the manufacturing process of feather meal, in order to increase the protein content (PC) and digestibility value (DV), and to determine the variables and levels that can potentially influence the process of flour obtaining. The experimental part of this work is presented in three chapters: the first chapter we evaluated the variability of TP and RV feather meal of chicken and turkey as a function of process parameters. There is a great difficulty in the standardization of feather meal containing chicken feathers and turkey. The pressure and time of hydrolysis differed among the raw materials. Both the variable pressure as the hydrolysis time affected in PC and DV. The highest scores were obtained for 100% flour made of chicken feathers. In chapter 2 we evaluated the influence of pre-drying step in PC and DV feather meal. We used a factorial design and response surface methodology to assess this effect. The pressure, hydrolysis time, length of pre-drying and composition of different raw materials were determined as independent variables, while the variables were PC and DV. The increase in the pre-drying time was significant (p<0,05) to increase the variables. The inclusion of turkey feathers was significant (p<0,05) in obtaining feather meal, a reduction in both the results of TP as in RV flours. In chapter 3 we evaluated the effect of adding different percentages of blood on the response variables, PC and DV, feather meal. We used a factorial design and response surface methodology to assess this influence. The independent variables were pressure, hydrolysis time, raw material and adding blood. The higher PC was obtained by measuring blood of 20% for the two raw materials. The levels of the process variables which are obtained with the highest TP (84,56%) and VD (47,96%) was 2,5 kgf.cm-2 pressure and 40 min. hydrolysis. The increase in the percentage of blood and the hydrolysis time was significant (p<0,05) increase both the PC and DV as feather meal. With the incorporation of turkey feathers there was a significant reduction (p<0,05) in PC and DV flours.
