25. Bacterial Cellulose Membranes as a Potential Drug Delivery System for Photodynamic Therapy of Skin Cancer
The development of drug delivery systems for photodynamic therapy (PDT) is increasingly demanded due to the hydrophobicity presented by most of photosensitizers molecules. Bacterial cellulose (BC), a highly pure cellulose produced by bacteria, possesses the essential features for applications in drug delivery systems, such as large surface area and excellent

26. Poultry Litter and Pig slurry Applications in an Integrated Crop-Livestock System
ABSTRACT Organic fertilizers derived from poultry litter and pig slurry are alternatives to mineral fertilizers in increasing soil nutrient availability. The aim of this study was to evaluate soil response, through characterization of organic C and available N, P, and K contents, and corn yield response to increasing amounts of poultry litter, pig slurry, an

27. Mine/Mill production planning based on a Geometallurgical Model
Abstract The Pau Branco mine supplies two blast furnaces with iron ore lumps, and currently, charcoal consumption for pig iron production accounts for 47% of the blast furnaces' operational cost. A geometallurgical model is presented to support an economic study considering reserve volumes, product quality, and operational costs based on the metallurgical pe

28. Antibiotic resistance and integrons in Shiga toxin-producing Escherichia coli (STEC)
Shiga toxin-producing Escherichia coli (STEC) cause hemorrhagic colitis (HC) and hemolytic-uremic syndrome in humans (HUS). Cattle are the main reservoir of STEC and transmission to humans occurs through contaminated food and water. Antibiotics are used in pig production systems to combat disease and improve productivity and play a key role in the disseminat

29. Nanoparticles containing curcuminoids (Curcuma longa): development of topical delivery formulation
Solid lipid nanoparticles incorporating Curcuma longa L., Zingiberaceae, curcuminoids were produced by the hot melt emulsion method. A Box–Behnken factorial design was adopted to study the nanoparticles production at different levels of factors such as the percentage of curcuminoids, time of homogenization and surfactant ratio. The optimized nanoparticles

30. Comparison of extensive and intensive pig production systems in Uruguay in terms of ethologic, physiologic and meat quality parameters
The objective of this work is to characterize two contrasting systems of fattening pigs in Uruguay. A total of 96 pigs (average 41.7 kg) were divided into eight groups of 12 animals, representing two production systems: (IN) pigs confined in pens of 12 m² or (OUT) kept in plots with field shelters and access to pasture. Behavioral observations were performe

31. BIOPOLÍTICA, GRIPE A (H1N1) E MÍDIA: O QUE PODE UM PORCO? / BIOPOLITICS, INFLUENZA A (H1N1) AND MEDIA: WHAT CAN A PIG?
This study aimed to analyze how biopolitics encompasses the dis-media courses in a newspaper circulating in the central region of Rio Grande do Sul on Influenza A (H1N1), seeking to make visible how the institutional and discursive practices and are cross the subjects. As specific objectives, we aim to identify, in the symbolic forms of the newspaper, the wa

32. Efeitos da temperatura ambiente e níveis de fósforo dietético na expressão gênica de suínos / Effects of thermal environment and dietary phosphorus levels in pig gene expression
O objetivo do estudo foi identificar genes codificantes para os complexos enzimáticos da cadeia tranpostadora de elétrons (CTE) que apresentam-se diferencialmente expressos no músculo Longissimus dorsi (LD) de suínos bem como seus padrões de expressãos de acordo níveis de fósforo disponíveis (Pd) na dieta e ambientes térmicos em duas fases de cresc

33. Hepatitis E virus in liver and bile samples from slaughtered pigs of Brazil
The objective of this study was to detect and identify hepatitis E virus (HEV) strains in liver and bile samples from slaughtered pigs in the state of Paraná, Brazil. Liver and bile samples were collected from 118 asymptomatic adult pigs at a slaughterhouse in a major Brazilian pork production area. The samples were assayed using a nested reverse transcript

34. Dry matter production and nitrogen use efficiency of giant missionary grass in response to pig slurry application
This study assessed the effect of successive applications of pig slurry on the dry matter (DM) production and the nitrogen use efficiency of giant missionary grass along two years. A total of 55, 110, 165, 220 and 275 m³ of pig slurry/ha/year were applied in order to supply 100, 200, 300, 400 and 500 kg of total N/ha/year, respectively. These treatments wer

35. PARASITOSES E DESEMPENHO ANIMAL: ESTUDO META-ANALÍTICO EM FRANGOS DE CORTE E SUÍNOS EM CRESCIMENTO / PARASITOSIS AND ANIMAL PERFORMANCE: META-ANALYTICAL STUDY IN BROILER AND GROWING PIGS
Dois trabalhos foram desenvolvidos com o objetivo de estudar, através de meta-análise, a relação das parasitoses com o desempenho de frangos de corte e suínos. As bases de dados totalizaram 43.976 frangos de corte (69 artigos, publicados entre 1982 e 2010) e 1.279 suínos (18 artigos, publicados entre 1971 e 2010). A meta-análise foi realizada através

36. Differentially expressed genes and miRNA identification in pig skeletal muscle / Identificação de genes diferencialmente expressos e miRNAs em músculo esquelético de suínos
The pig (Sus scrofa) is considered an important animal for meat production. This interest revolves around the potential for muscle growth, which usually is associated with certain characteristics during prenatal myogenesis. To study the genes responsible for these characteristics, expressed sequence tags (EST) provide direct information about the transcripto
