ABSTRACT The objective of this study was evaluate whether pretransport feed withdrawal affects welfare, carcass, and meat characteristics of European quails. A total of 120 European quails were used, with an initial age of 15 days. Bird feed was removed before transport to the slaughterhouse at the following times, which characterised the different treatments: zero hours, three hours, six hours, nine hours and twelve hours. The transport took 54 minutes to cover 27 kilometres to a commercial slaughterhouse. The birds were slaughtered at 41 days of age. During bleeding, blood samples were collected. Blood glucose, total protein, albumin, uric acid, and corticosterone concentrations were measured. The carcasses and meat characteristics were measured. Poultry body weight decreased and blood glucose concentrations increased with the increase in feed withdrawal time. The treatments did not affect carcass weights. Carcass yields after three hours fasting were similar to those in the six hours and nine hours groups, indicating that gastrointestinal tracts were empty after the third hour. Meat quality was negatively affected (pH, lightness, water holding capacity, cooking loss) by the increase in feed withdrawal time; integrated parameters that characterise dark, firm, dry meat. Pre transport feed withdrawal time should be three hours to empty the gastrointestinal tract and minimise losses in meat quality of European quails. It is necessary to adjust feed withdrawal so that it does not exceed this time, since there is no technical justification for supporting it.

ABSTRACT (150 words) (same order that title) The practice of sports has been considered one of the main tools for the life skills development among youth sport participants. This cross-sectional study investigated the predicting role of age and time of practice in the development of life skills among 207 male youth futsal practitioners from the state of Pernambuco, Brazil. The instruments used were the Life Skills Scale for Sports and a semi-structured questionnaire. Data analysis was conducted through Multivariate Analysis of Variance, Pearson's correlation and Multiple Regression (p<.05). The results showed significant difference (p<.05; η2=.036-.142) in all life skills according to age group, evidencing higher scores for older adolescents. Further, more experienced adolescents showed higher scores at goal seating (p=.001, η2=.074); problems solving (p=.013, η2=.042), communication (p=.003, η2=.054) and total life skills (p=.002, η2=.057). There was significant (p<.05) and positive correlation between age and almost all life skills subscales. Multiple regression revealed only age presented positive prediction toward life skills. It can be concluded that age is a predictor of life skills development among youth futsal practitioners.

RESUMO (1500 palavras) (mesma ordem como títulos) A prática esportiva tem sido considerada uma das principais ferramentas para o desenvolvimento de habilidades para a vida entre jovens praticantes de esportes. Este estudo transversal investigou o papel preditivo da idade e do tempo de prática no desenvolvimento de habilidades para a vida em 207 jovens praticantes de futsal do sexo masculino do estado de Pernambuco, Brasil. Os instrumentos utilizados foram a Escala de Habilidades para a Vida Esportiva e um questionário semiestruturado. A análise dos dados foi realizada por meio da Análise Multivariada de Variância, correlação de Pearson e Regressão Múltipla (p<0,05). Os resultados mostraram diferença significativa (p<0,05; η2=0,036-0,142) em todas as habilidades para a vida de acordo com a faixa etária, evidenciando escores mais altos nos adolescentes mais velhos. Além disso, os adolescentes mais experientes apresentaram pontuações mais altas nos assentos para as metas (p=0,001; η2=0,074); resolução de problemas (p=0,013, η2=0,042), comunicação (p=0,003, η =0,054) e habilidades totais para a vida (p=0,002, η2=0,057). Houve correlação significativa (p<0,05) e positiva entre idade e quase todas as subescalas de habilidades para a vida. A regressão múltipla revelou que apenas a idade apresentou predição positiva em relação às habilidades para a vida. Pode-se concluir que a idade é um preditor do desenvolvimento de habilidades para a vida entre jovens praticantes de futsal.

Los resultados mostraron una diferencia significativa (p <.05; η2=.036-.142) en todas las habilidades para la vida según el grupo de edad, evidenciando puntuaciones más altas para los adolescentes mayores. Además, los adolescentes más experimentados mostraron puntajes más altos en la meta sentada (p=.001, η2=.074); resolución de problemas (p=.013, η2=.042), comunicación (p=.003, η2=.054) y habilidades para la vida total (p=.002, η2=.057). Hubo una correlación significativa (p<.05) y positiva entre la edad y casi todas las subescalas de habilidades para la vida. La regresión múltiple reveló que solo la edad presentaba predicciones positivas hacia las habilidades para la vida. Se puede concluir que la edad es un predictor del desarrollo de habilidades para la vida entre los jóvenes practicantes de fútbol sala.

The comprehension of the pathogenesis of Trypanosoma cruzi-elicited myocarditis is crucial to delineate new therapeutic strategies aiming to ameliorate the inflammation that leads to heart dysfunction, without hampering parasite control. The augmented expression of CCL5/RANTES and CCL3/MIP-1alpha, and their receptor CCR5, in the heart of T. cruzi-infected mice suggests a role for CC-chemokines and their receptors in the pathogenesis of T. cruzi-elicited myocarditis. Herein, we discuss our recent results using a CC-chemokine receptor inhibitor (Met-RANTES), showing the participation of CC-chemokines in T. cruzi infection and unraveling CC-chemokine receptors as an attractive therapeutic target for further evaluation in Chagas disease.
