Dilemas e hesitações da modernidade tardia e a emergência da sociedade de controle

The objective of this study is to emphasize the fundamental points of the theoretical discussion about late modernity. In the two last decades, authors like Giddens, Beck, Bauman, Sennett and Garland have emphasized the social, historical and theoretical characterization of modernity in the advanced occidental societies. This discussion, despite being indispensable, does not allow the comprehension of the problems of this new stage of occidental capitalism in terms of its technical dimension and social control. The article arguments in favor of the incorporation of analysis of Michel Foucault’s power and stresses its present reality and potential. This author renewed the theoretical possibilities of the human sciences as he criticized a naturalized view of History and historical events. The influence of his works, an analysis of modernity, may be observed in the debate around the crisis of modernity and the emerging society of control. At the same time, his work helps us understand the main dilemmas and hesitations of contemporary societies.

Model to estimate lysine requirements of broilers

The purpose of this study is to describe the development of a model to predict the digestible lysine requirements of broilers using the factorial approach, and to evaluate the model using as reference the model presented in Brazilian Tables for Poultry and Swine. The model partitions the requirement for maintenance and growth for feather-free body protein and feather protein, in which the inputs are body and feather protein weight and the daily rates of protein deposition in the feather-free body and feathers. The parameters that express the lysine requirement for maintenance were obtained in metabolism trials with roosters, and those for the efficiency of lysine utilization in experiments with broilers from 1 to 42 d. Based on these results the model proposed was: Lys (mg/d) = [(151xBP(m)(-0.27)xBP(t)) + (0.01xP(t)x18)] + [(75xBPD/0.77) + (18xFPD/0.77)], where Lys = digestible lysine requirement (mg/d), BPm=body protein weight at maturity (kg), BPt=body protein weight at time t (kg), FPt=feather protein weight at time t (kg), BPD=body protein deposition (g/d), FPD = feather protein deposition (g/d). The model yields sensible predictions of the digestible lysine requirements of broilers of different strains and ages growing at their potential, and suggests a lower lysine requirement after 27 d than does the Brazilian model. The proposed model is the first step in the development of a simulation model that predicts the food intake of a broiler and hence the dietary amino acid content that would optimise performance.

Comparação das técnicas semi-quantitativa e quantitativa nas infecções relacionadas a cateter em neonatos e determinação da resistência à oxacilina nos Staphylococcus spp

Study the semi-quantitative and quantitative technique in the diagnosis of catheter-related infections in newborns and to determine oxacillin resistance in Staphylococcus isolated. It was analyzed 353 catheter tips from 273 newborns in the Neonatal Unit of Hospital FMB. To confirm the diagnosis of infection, were analyzed the clinical data of newborns, the presence of at least one positive blood culture and growth of ≥ 1000 CFU/mL on quantitative culture and/or ³15 UFC on semiquantitative culture, with the same microorganism isolation (species and drug sensitivity) in blood culture and no other focus of infection except the catheter. The disk diffusion technique was used to check similarity of strains and resistance to oxacillin. Of the 353 tips analyzed, 39 were included in this study as the inclusion criteria. The semiquantitative culture was positive in 26 (66.7%) catheters and quantitative culture was positive in 24 (61.5%). Of 273 patients, 19 (6.9%) had a diagnosis of catheter-related bloodstream Infection (CR-BSI). Of the 19 episodes of CR-BSI, S. epidermidis was the predominant etiological agent (84.2%). The resistance to the antibiotic methicillin was found in 14 (73.7%) strains of Staphylococcus. The semiquantitative method was more sensitive (79%) compared with the quantitative method (63%). The use of antibiotics may have influenced the sensitivity of the quantitative method as the microorganisms present in the lumen are exposed to higher concentrations of antibiotics administered via the catheter

Leuconostoc mesenteroides SJRP55: a potential probiotic strain isolated from Brazilian water buffalo mozzarella cheese

The probiotic potential of Leuconostoc mesenteroides subsp. mesenteroides SJRP55 isolated from water buffalo mozzarella cheese was evaluated. The microorganism presented resistance to stressful conditions that simulated the gastrointestinal tract, and to the best of our knowledge Leuconostoc mesenteroides SJRP55 was the first of this species with the ability to deconjugate bile salts. Tolerance to NaCl was temperature dependent, as well the results obtained by aggregation capacity. The strain presented good adhesion properties, β galactosidase activity, viability in fermented milk during storage, non-active against Streptococcus thermophilus and sensible to most of the tested antibiotics. Some analgesic medications inhibited the growth of the strain. Leuconostoc mesenteroides SJRP55 exhibited in vitro probiotic potential, and it can be better characterized through future in vivo tests. This bacterium presents higher functional properties compared to other studied strains, and therefore it is a potential candidate for the application as a probiotic strain, which could be used by industries in the manufacture of functional milk-based products.
