2. Artificial neural network for prediction of the area under the disease progress curve of tomato late blight
ABSTRACT: Artificial neural networks (ANN) are computational models inspired by the neural systems of living beings capable of learning from examples and using them to solve problems such as non-linear prediction, and pattern recognition, in addition to several other applications. In this study, ANN were used to predict the value of the area under the diseas

3. Association among measures of mobility-related disability and self-perceived fatigue among older people: a population-based study
Objective: To investigate the relationship between self-perceived fatigue with different physical functioning tests and functional performance scales used for evaluating mobility-related disability among community-dwelling older persons. Method: This is a cross-sectional, population-based study. The sample was composed of older persons with 65 years of age

4. Modelos epidemiológicos alternativos da malária / Epidemiologic alternative models of malaria
Neste trabalho apresentamos um estudo de modelos matemáticos epidemiológicos determinísticos da malária. Em seguida propomos um modelo alternativo da malária, supostamente menos complexo com o intuito de utilizar modelos associados que contemplam a subjetividade em seus elementos. Para o modelo alternativo determinístico fizemos uma análise qualitativ

5. Theoretical, behavioral and neuroimage evidence on discourse processing aging
A growing interest in cognition in aging has been observed because of both the epidemiologic factor of an increase in the lifespan of the world's population and the cognitive changes behaviorally and biologically detectable in this population. The most complex of language components and fundamental in social interaction, discourse production and comprehensio

6. Uso de modelos de análise de decisão nos programas de vacinação contra a varicela / Use of decision analysis models in the programs of vaccination against varicella
BACKGROUND: The choice between different decision analysis models introduces variability in the results of economic evaluations. Static models do not take into account the indirect effects of vaccination, thus compromising the overall assessment of vaccination benefits. This work developed two models one dynamic and another static to conduct cost-effectivene

7. Mathematical Model to study the spread of information from educative campaigns and rumors / Modelo matemático para o estudo da propagação de informações por campanhas educativas e rumores
We have developed a deterministic mathematical model based on the mass-action principle, in analogy to the works that study the dynamics of infectious diseases in Epidemiology. We analyzed the dynamic of rumors spreading, taking into account the symmetry of contacts among susceptible and infectious individuals and studied the implications of an educative bro

8. Exploration of variable selection methods by logistic regression techniques for epidemiologic data analysis / Exploração de metodos de seleção de variaveis pela tecnica de regressão logistica para analise de dados epidemiologicos
n this work it was discussed the application of two methods for selection of predictor variables and models in multiple logistic regression analysis: hierarchical model and a stepwise model. In a case-control study conduced to identify risk factors associated to neonatal mortality in Campinas, São Paulo, the effects of socio-economic, maternal morbidity and

9. DNA ploidy, nuclear grade and architectural changes in ductal carcinoma in situ and in invasive female breast cancer: a contributory study for the model of disease progression / Ploidia de DNA, grau nuclear e alterações arquiteturais no carcinoma in situ e no carcinoma ductal invasivo da mama feminina: uma contribuição para o estudo do modelo de progressão de doença
Carcinogenesis is a multiple stage phenomenon. Epidemiologic evidence indicates that progression to invasive breast cancer begins in hyperplastic states of the epithelium passing by in situ carcinoma. The actual relationship that exists between ductal carcinoma in situ and invasive ductal carcinoma of the breast and the factors that lead to the tumor invasio

10. Assistir e vigiar - As ações da vigilância epidemiológica na unidade básica de saúde. Situação atual e perspectivas / Care and Vigilance. The actions of Epidemiological Surveillance at Basic Health Units. Actual situation and perspectives 2003
Historically, the Information System of Compulsory Notification Diseases has been the main instrument of Epidemiological Surveillance. The diseases that are part of this system have been those that can cause risk to the collective health and, traditionally, are restricted to the transmissible diseases, even though that in the present Guide other circumstance

11. Os sistemas públicos de informação em saúde na tomada de decisão - rede básica de saúde do munícipio de Ribeirão Preto / "Public health information in the decision making at basic care-Ribeirão Preto-SP"
The thematic of this study is information in health, one of the areas of collective health, since it is inserted in health policies for individual and a collective health promotion, prevention and recuperation, considering the social determinations of the health-illness process and yet, for serving as an analysing tool of the production of health actions, in

12. Estrogenic modulation of brain activity:implications for schizophreniaand Parkinson's disease
Evidence suggests the estrogens may play a role in various mental and neurodegenerative diseases. We review the evidence implicating estradiol in schizophrenia and Parkinson's disease. Epidemiologic and clinical studies on the effects of estrogens in schizophrenia are surveyed, and animal studies and in vitro models of the modulatory effects of estrogens on
