Pregnant female mice were divided into two groups, a control group and a CR group (n=7 in each). Mice in the CR group were fed 50% of the amount consumed by control females from Day 10 of gestation until delivery. After weaning, the offspring received diet ad libitum until 3 months of age, when ovaries were collected. Ovaries were serially cut and every sixth section was used for follicle counting. Female offspring from CR dams tended to have increased bodyweight compared with offspring from control females (P=0.08). Interestingly, fewer primordial follicles (60% reduction; P=0.001), transitional follicles (P=0.0006) and total follicles (P=0.006) were observed in offspring from CR mothers. The number of primary, secondary and tertiary follicles did not differ between the groups (P>0.05). The CR offspring had fewer DNA double...

A escolha do tema emergiu da necessidade de se conhecer as importância das intervencoesda equipe multiprofissional e dos resultados dessa atuacao nessa modalidade cirurgica. Trata-se de umestudo eminentemente bibliografico, utilizando-se de analise de literatura especializada. Objetivousaber os significados da cirurgia bariatrica, identificar o significado da cirurgia para os pacientes que aela se submetem e constatar atuacao da equipe multiprofissional. O resultado da revisao de literaturadesvelou a motivacao dos pacientes que passam por tal cirurgia, elucidando a atuacao da equipemultiprofissional, e sua imprescindibilidade em todas as fases deste tipo de cirurgia.

However, studies associating genetics, dietary patterns and PON1 activity in individuals with cardiovascular disease (CVD) are scarce. Thus, the aim of the current study was to evaluate the influence of dietary factors on serum PON1 in CVD patients. Subjects and methods: Cross-sectional, sub-study of the BALANCE Program Trial. All patients aged 45 years or older and had evidence of established atherosclerotic disease in the preceding 10 years. Body weight, height, waist circumference, blood pressure, lipid profile and fasting glucose were collected. Food intake was assessed with 24-h dietary recall. Data was analyzed using SAS University Edition and a P value ≤ 0.05 was considered statistically significant. Sample was divided into three groups, according to the PON1 T(-107)C genotype (CC, CT and TT) and serum PON1 activity (Low, Medium, High). Results: There were no genotype differences for major factors. However, the systolic blood pressure was lower for CT individuals (p<0.05). Intake of cholesterol, saturated fatty acids (SFA) and monounsaturated fatty acids (MUFAS) was higher in patients with lower PON1 activity. Lipid ingestion tended to be higher in patients with lower PON1 activity (p=0.08). In the multivariate logistic regression model, SFA intake (P=0.03), genotype (P=0.09), gender (P=0.04), age (P=0.07) and carbohydrate intake (P=0.16) contributed the most to the serum PON1 activity. Conclusion: Based on these findings, nutritional guidance for these patients becomes essential, since dietary components interact with serum PON1 activity more than genotype.

However, for processes that are not well structured and have a lot of diverse behavior, existing process mining techniques generate highly complex models that are often difficult to understand; these are called spaghetti models. One way to try to understand these models is to divide the log into clusters in order to analyze reduced sets of cases. However, the amount of noise and ad-hoc behavior present in real-world logs still poses a problem, as this type of behavior interferes with the clustering and complicates the models of the generated clusters, affecting the discovery of patterns. In this work we present an approach that aims at overcoming these difficulties by extracting only the useful data and presenting it in an understandable manner. The solution has been implemented in ProM and is divided in two stages: preprocessing and sequence clustering. We illustrate the approach in a case study where it beco...

Permite captar luz e transformar essa percepcao em impulsos eletricos, formando a imagem invertida e captada novamente pelo cerebro. Com o passar do tempo, esse orgao precioso comecou a passar por transformacoes e consequentemente se originaram alguns problemas, como a miopia, hipermetropia, presbiopia, catarata astigmatismo e o daltonismo sendo os principais defeitos que atingem a visao humana. Com este trabalho pretendemos mostrar as principais causas e consequencias dos defeitos citados, seguido de possiveis tratamentos com uso de lentes especificas para correcao ou cirurgias para a melhora dos mesmos.
