Três experimentos foram conduzidos com linhagens comerciais de frangos de corte em baterias metálicas para determinar a biodisponibilidade relativa de duas fontes de grupamentos metílicos (metionina e betaína). A dieta basal (controle) foi formulada com milho e farelo de soja, contendo 1.896, 1.969 e 2.010 mg/kg de colina no experimento I, II e III, respectivamente. Os níveis suplementados em betaína e metionina foram isomolar. O experimento I (fêmeas até 21 dias de idade) constou de seis níveis de metionina (0; 5,36; 10,72; 16,08; 21,45; 32,17 mMol/kg) e dois níveis de betaína (0 e 5.36 mMol/kg). No experimento II (machos até 21 dias de idade) a dieta controle foi suplementada com 0; 2,68; 5,36; 8,04; 10,72; 13,40 mMol/kg de metionina ou 0; 2,68; 5,36; 8,04; 10,72; 13,40 mMol/kg de betaína. Em relação ao experimento III (machos até 21 anos de idade) houve quatro níveis de metionina (0; 8,04; 10,72 e 13,40 mMol) e três níveis de betaína (0; 6,7 e 13,4 mMol). Para o experimento I e III foram utilizados quatro repetições de oito aves para cada tratamento. O experimento II apresentou quatro repetições para cada tratamento e oito repetições para o grupo controle, apresentando também oito aves por parcela experimental. Foi constatado para os experimentos I, II e III que os valores de inclinação da curva pra a betaína e metionina foram significativos para o peso corporal e conversão alimentar. No experimento III somente o valor de inclinação para a curva da metionina foi significativo, em relação ao consumo alimentar. No experimento III somente o valor de inclinação para a curva da metionina foi significativo, em relação ao consumo alimentar. Nem a metionina ou a betaína diminuíram a gordura abdominal em nenhum dos experimentos. Em média, os dados do experimento II e III indicaram que a biodisponibilidade relativa...

Na análise da significação da frase, há necessidade de distinguir dois níveis: o elocucional e o proposicional. Ambos devem ser considerados na representação semântica da frase, projetada como um conjunto de predicações dispostas em níveis estratificados. O estrato existencial e o do conteúdo objetivo têm relação estrutural mútua, constituindo o cerne da proposição. Nesta, os verbos apresentam certas categorias semânticas que propiciam relações apropriadas com os nomes a eles associados, determinando suas funções semânticas. Para a análise desse problema, busca-se integrar os sistemas de Fillmore, Chafe e Jackendoff num modelo único. A partir de traços básicos, analisa-se sua combinação com outros mais especificadores, que levam a relações abstratas com os argumentos; três funções são depreendidas em cada tipo de relação. Ressalta-se, por fim, o alcance explicativo de um sistema que considera relações e funções semânticas na descrição dos fatos da língua.

The objective of this work was to evaluate the inter-relationship between dietary supplementation with Saccharomyces cerevisiae cell wall and vaccination against Streptococcus agalactiae, and its effect on the productive performance and hematological variables of Nile tilapia (Oreochromis niloticus). Eighty-four Nile tilapia were distributed in 12 fiber boxes (n=7), in a 2x2x3 factorial arrangement, corresponding to two levels of supplementation with yeast cell wall, two types of inoculation, and three evaluation times. Fish were fed during 77 days. Vaccination of fish was done 60 days after feeding started. Fifteen days after vaccination, all fish were subjected to challenge with live strain of S. agalactiae, and 6, 24, and 48 hours after the challenge, blood was collected from the caudal vein for evaluations. Fish fed with supplemented diets show greater weight gain and specific growth rate, and the interaction between the diet and vaccination effects results in higher hematocrit, hemoglobin, and leukocyte rates.

The aim of this work was to evaluate the performance and the liver structure health of Nile tilapia hormonally masculinized or nonmasculinized, reared in cages with two protein levels. Two groups of Nile tilapia of Thai lineage (total 2,400), with 127 g initial average weight, were distributed in a completely randomized design with four treatments, in a 2x2 factorial arrangement, corresponding to the groups of hormonally masculinized or nonmasculinized fish, and to diet protein level of 28 or 32% of crude protein, with three replicates. After 115 days feeding, there was no interaction between the factors for final weight, weight gain, feed conversion rate, final length and survival. There was no difference between hormonally masculinized and nonmasculinized fish for final weight, weight gain, and survival, which shows the possibility of their production in cages, without the need of hormonal masculinization. Crude protein at 32% in the diet enables a better performance for both groups. Histological changes in the liver - such as increased cell volume, disruption of the cord-like arrangements, and increase of vesicles in the hepatocytes - are found in hormonally masculinized fish, and are more pronounced in fish fed 32% crude protein in the diet.

The artistic gymnastics is a modality that associates arts with biomechanical gestures, and it has been prominent among children and adolescents. Its practice can lead to sports injuries; therefore, it is important to know the factors inherent to trauma for the formulation of preventive models. Thus, the objective of this study was to characterize sports injuries and to verify factors associated with injury in people practicing artistic gymnastics with different levels of competitiveness. Forty-six gymnasts were interviewed with mean age of 10.1±2.0 years for female participants, who were classified in two competitive levels, i.e, initiation and training. We used the morbidity questionnaire adapted to sports characteristics to collect personal, training, and injury data. It was observed that injury risk was 0.3 injuries per athlete and 1.4 injuries per injured athlete, in which the gymnasts of the training category showed a higher frequency of the injury (83.3%; n=10) compared with the ones in the initiation category (10.5%; n=4). For both levels of competitiveness, training moment and light severity were the most reported variables. In the mechanism, contactless was more prevalent in the training category (90%; n=9) and the direct contact was more common at initiation category (75%; n=3). Anthropometric and training variables were considered as factors associated with injury to the gymnasts. It is concluded that gymnasts of the training category have higher injury frequency. Anthropometric and training variables were factors associated with injury. Characteristics of the injuries depend on the competitiveness level of the gymnasts.

This study was carried out in Fazenda Canchim in Sao Carlos-SP, physical base of Embrapa Southeast Livestock, aiming to select, based on the agronomic characteristics of productivity of dry matter and quality of the forage, the accesses of suitable gender Paspalum for possessing potentiality of use as foraging plants. Were evaluated for 3 years, with 22 forage grasses, being 19 of Paspalum and three more of control species: Brachiaria decumbens, Andropogon gayanus cv. Baet and Panicum maximum cv. Tanzania, submitted to two intensification levels: high (fertilizer after each cut and supplemental irrigation) and low (only fertilizer of annual replacement without irrigation). The experimental design was of split blocks subdivided in the space and time with two replications. The studied variables were: dry matter production, in vitro dry matter digestibility and crude protein content. The results show that the accesses responded to the intensification level minimizing the negative effect of the stational production. Based on the studied variables, the selected accesses were: BRA-011401 (Paspalum glaucescens); BRA-011681 (P. atratum); BRA009661 (P. atratum) and BRA-019186 (P. regnellii).
