13. Association of Surfactant-Associated Protein D Gene Polymorphisms with the Risk of COPD: a Meta-Analysis
The relationship between surfactant-associated protein D polymorphisms and chronic obstructive pulmonary disease risk remains controversial. This article is the first to systematically evaluate this relationship. A comprehensive worldwide search was conducted for relevant literature on surfactant-associated protein D gene mutations and chronic obstructive pu

14. Fatores socioeconômicos aumentam os efeitos nocivos da poluição atmosférica e da temperatura na mortalidade
RESUMO: Objetivo: Verificar os efeitos do PM2,5 e da temperatura na mortalidade por doenças cardiovasculares segundo status socioeconômico e proximidade do tráfego. Método: Utilizaram-se séries temporais por meio da classe dos modelos aditivos generalizados com a opção de regressão de Poisson, a 5% de significância. Analisou-se interação entre

15. Random regression models with B-splines to estimate genetic parameters for body weight of young bulls in performance tests
ABSTRACT The objective of this study was to estimate genetic parameters for body weight of beef cattle in performance tests. Different random regression models with quadratic B-splines and heterogeneous residual variance were fitted to estimate covariance functions for body weights of Nellore and crossbred Charolais × Nellore bulls. The criteria −2 residu

16. Application of bayesian additive regression trees in the development of credit scoring models in Brazil
Abstract Paper aims This paper presents a comparison of the performances of the Bayesian additive regression trees (BART), Random Forest (RF) and the logistic regression model (LRM) for the development of credit scoring models. Originality It is not usual the use of BART methodology for the analysis of credit scoring data. The database was provided by Se

17. The mechanism of drug interactions of a selected antiarrhythmic drug with metformin, in different animal models
ABSTRACT This study was carried out to understand the influence of a selected antiarrhythmic drug on the pharmacodynamics and pharmacokinetics of an antidiabetic drug in animal models. Pharmacodynamic and pharmacokinetic responses were determined by measurements of blood glucose and serum insulin and serum metformin to drug interactions between disopyramide

18. In vitro fermentation characteristics of ruminant diets using ethanol extract of brown propolis as a nutritional additive
ABSTRACT The addition of levels of ethanol extract of brown propolis was evaluated by assessing diet degradation in rumen fluid and predicting cumulative in vitro gas production by nonlinear (dual pool logistic and exponential) models. A total of 35 g of crude propolis were extracted in 65 mL of cereal alcohol (95% ethanol). In a completely randomized factor

19. Software Selegen-REML/BLUP: a useful tool for plant breeding
Abstract The software Selegen-REML/BLUP uses mixed models, and was developed to optimize the routine of plant breeding programs. It addresses the following plants categories: allogamous, automagous, of mixed mating system, and of clonal propagation. It considers several experimental designs, mating designs, genotype x environment interaction, experiments rep

20. Genetic analysis of reciprocal differences in the inheritance of in vitro characters in pearl millet
Abstract Reciprocal differences persist in nature because of the unequal contribution of cytoplasmic determinants from male and female gametes to the zygote. The inheritance of genetic differences is an important factor that influences various traits, including somatic embryogenesis and regeneration in vitro. In this report, we estimate the cytoplasmic and m

21. Association between NOx exposure and deaths caused by respiratory diseases in a medium-sized Brazilian city
Exposure to nitrogen oxides (NOx) emitted by burning fossil fuels has been associated with respiratory diseases. We aimed to estimate the effects of NOx exposure on mortality owing to respiratory diseases in residents of Taubaté, São Paulo, Brazil, of all ages and both sexes. This time-series ecological study from August 1, 2011 to July 31, 2012 used infor

22. Development of standardized extractive solution from Lippia sidoides by factorial design and their redox active profile
AbstractThe aim of this study was to evaluate the influences of variables of preparation on total flavonoids content from extractive solution of Lippia sidoides Cham., Verbenaceae. Thus a 23 factorial design was used to study the importance of plant proportion, the extraction method and solvent on the extraction of flavonoid. The methodology of determination

23. Reaction norms models in the adjusted weight at 550 days of age for Polled Nellore cattle in Northeast Brazil
The objective of this study was to evaluate the genotype-environment interaction (GEI) in the body weight adjusted to 550 days of age (W550) of Polled Nellore cattle raised in Northeastern Brazil using reaction norms (RN) models. Hierarchical RN models included fixed effects for age of cow (linear and quadratic) and random effects for contemporary groups (CG

24. Inheritance of soybean resistance to Rotylenchulus reniformis
Genetic inheritance of soybean resistance to Rotylenchulus reniformis was studied by evaluating the phenotypic reaction of soybean plants to the nematode. The resistant (Forrest and Custer) and susceptible (BR96-25619) soybean cultivars used as parents as well as the F1, F2 and F2:3 derived from their crosses were infested individually with 1,000 eggs and ve
