TL;DR: The results suggest that raw or rare cooked meat may an important way of transmiting toxoplasmosis to humans in this region and suggest that carnivores, herbivores, and omnivores are exposed to the same sources of transmission.
Abstract: Toxoplasma gondii the agent causing toxoplasmosis has a worldwide distribution. In the present study we attempt to determine the prevalence of toxoplasmosis in food animals and horses from farms in Jaguapita county. IgG antibody were detected using indirect immunofluorescence. Titers higher or equal to 1:64 were considered reactive. We found prevalence rates of 24% (267) for swine, 25.8% (400) for bovine , 51.8% (228) for ovine samples, and 12.1% (173) for equine. Seropositivity increased with age in sheeps and pigs, there were no gender differences in the species studied. There was a positive and significant correlation between human and feline (r= 0.64 p=0.05), human and canine (r=0.78 p=0.01), canine and swine (r=0.96 p=0.0001), bovine and ovine (r=0.82 p=0.006), bovine and equine (r=0.89 p=0.001), and ovine and equine (r=0.92 p=0.0004) titers. These results suggest that carnivores, herbivores, and omnivores are exposed to the same sources of transmission. Toxoplasmosis has a high prevalence on the studied population. Our results suggest that raw or rare cooked meat may an important way of transmiting toxoplasmosis to humans in this region.

TL;DR: In this paper, an amostra representativa de adolescentes matriculados em escola de ensino medio do municipio de Londrina, Parana, Brazil, was investigated.
Abstract: Beneficios da pratica de atividade fisica e riscos do sedentarismo associados a saude e ao bem-estar sao amplamente documentados na literatura. No entanto, maior numero de estudos procura envolver sujeitos adultos. Pouco se conhece com relacao aos habitos de pratica de atividade fisica de adolescentes. O objetivo do estudo foi analisar niveis de pratica de atividade fisica habitual em amostra representativa de adolescentes matriculados em escola de ensino medio do municipio de Londrina, Parana. A amostra foi constituida por 281 adolescentes (157 mocas e 124 rapazes) com idade entre 15 e 18 anos. Informacoes acerca da atividade fisica habitualmente realizada foram obtidas mediante instrumento retrospectivo de auto-recordacao das atividades diarias. Estabeleceram-se estimativas quanto a demanda energetica (kcal/kg/dia) com base no custo calorico associado ao tipo e a duracao das atividades registradas pelos adolescentes. Os resultados revelam que rapazes foram consistentemente mais ativos fisicamente que mocas. Por volta de 54% dos rapazes envolvidos no estudo foram classificados como ativos ou moderadamente ativos, enquanto aproximadamente 65% das mocas analisadas mostraram ser inativas ou muito inativas. Os rapazes demonstraram significativamente maior envolvimento na pratica de exercicios fisicos e de esportes que mocas (3:20 vs. 0:48 horas/semana). Os niveis de pratica de atividade fisica habitual tenderam a reduzir-se com a idade, sobretudo entre mocas. As mocas permaneceram menor tempo em frente da TV e do video que rapazes (3:30 vs. 4:00 horas/dia). Rapazes, porem nao mocas, pertencentes a classe socioeconomica familiar mais baixa mostraram ser menos ativos fisicamente que seus pares de classe socioeconomica familiar mais privilegiada. A maioria dos adolescentes (97% das mocas e 74% dos rapazes) nao atende as recomendacoes quanto a pratica de atividade fisica que possa alcancar impacto satisfatorio a saude. Como conclusao, a elevada incidencia de sedentarismo observada na amostra analisada sugere acoes intervencionistas que venham incentivar a pratica adequada de atividade fisica na populacao jovem.

TL;DR: Starch and PVC films significantly reduced decay of the fruits compared to control and presented the better behavior on weight and firmness retention of fruits, especially in the last 7 days of storage.
Abstract: Yam starch films, formulated with yam starch (4.00 g/100 g of solution) and glycerol (1.30 and 2.00 g/100 g of solution) in filmogenic solution, were employed as packaging to extend storage life of strawberries stored at 4 degrees C and 85% RH. The effects of yam starch films on fruits were compared to the effect of PVC (poly(vinyl chloride)) packaging. Starch and PVC films significantly reduced decay of the fruits compared to control. Compared to starch films, PVC presented the better behavior on weight and firmness retention of fruits, especially in the last 7 days of storage. Considering microbiological counts, the shelf life of control fruits was 14 days, and of all packaged samples, stored at same conditions, was 21 days. Two different formulations of yam starch film were tested and had different mechanical properties as a function of glycerol content (1.30 and 2.00 g/100 g of solution) but showed no difference when employed as strawberries packaging.
