13. Variáveis meteorológicas e poluição do ar e sua associação com internações respiratórias em crianças: estudo de caso em São Paulo, Brasil
As transformações no clima urbano das cidades, a excessiva poluição atmosférica e o aumento das desigualdades sociais tornaram-se fatores determinantes do alto risco de internações por doenças respiratórias. Dessa forma, o objetivo deste trabalho foi compreender como os atributos meteorológicos (temperatura do ar, umidade relativa do ar e precipita

14. Climatic Response of Cedrela fissilis Radial Growth in the Ombrophilous Mixed Forest, Paraná, Brazil
ABSTRACT We examined the climatic response of Cedrela fissilis radial growth based on precipitation, air relative humidity, temperature and monthly thermal amplitude. It was intended to assess how the secondary growth of C. fissilis is influenced by the climatic variables and which one are the best growth predictors in Ombrophilous Mixed Forest, southern Bra

15. Association between consumption of ultra-processed foods and serum C-reactive protein levels: cross-sectional results from the ELSA-Brasil study
ABSTRACT BACKGROUND: There may be a direct association between consumption of ultra-processed foods and C-reactive protein (CRP) levels, under the assumption that the high glycemic index of these food products could stimulate the entire chronic inflammation cascade, along with an indirect association mediated by obesity. The types of food consumed, includi

16. Factors associated with the distribution of natural Toxoplasma gondii infection among equids in Northeastern Brazil
Resumo O objetivo deste estudo foi determinar a frequência e os fatores associados a Toxoplasma gondii em equídeos naturalmente infectados no Nordeste do Brasil. Amostras de soro de 569 equídeos (528 cavalos, 8 asnos e 33 muares) foram submetidas a reação de imunofluorescência indireta. Modelos lineares generalizados foram utilizados na avaliação dos

17. Remineralizing effect of commercial fluoride varnishes on artificial enamel lesions
Abstract: The aim of this study was to evaluate soluble and insoluble fluoride concentrations in commercial varnishes, and their remineralization effect on artificial caries enamel lesions using surface and cross-sectional microhardness evaluations. Forty bovine enamel blocks were separated into four groups (n=10): control (no treatment), Enamelast (Ultraden

18. 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

19. Frequency and factors associated with Theileria equi, Babesia caballi and Trypanosoma evansi in equids from Bahia (Northeast Brazil)
Resumo Este estudo teve como objetivos conhecer a frequência e os fatores associados à infecção por Babesia caballi, Theileria equi e Trypanosoma evansi em equinos naturalmente infectados do nordeste do Brasil. Amostras de sangue de 569 equídeos (528 equinos, 8 muares e 33 asininos) foram coletadas e testadas para a presença do DNA destes parasitos at

20. Effects of exposure to fine particulate matter in elderly hospitalizations due to respiratory diseases in the South of the Brazilian Amazon
Exposure to air pollution is an important cause of hospital admissions due to respiratory diseases. Nevertheless, few studies use pollutant concentration data estimated by mathematical models. A time-series ecological study was developed, using data from hospitalizations due to respiratory diseases in people over 60 years of age, residents of Cuiabá, Brazil

21. Stevia rebaudiana (Bert) Bertoni: regression models with mixed effects for investigating seed germination data
ABSTRACT. We investigated regression models with mixed effects using generalized linear statistics to evaluate germination data from Stevia rebaudiana (Bert) Bertoni. Estimates and validation of statistical parameters were conducted using the “gamlss” package in the R software. Generalized linear mixed effects followed the binomial, the beta-binomial and

22. Lizard assemblages on sandy coastal plains in southeastern Brazil: An analysis of occurrence and composition, and the role of habitat structure
Abstract Data on the structure of lizard communities in the different biomes and ecosystems of Brazil are still limited. In this study, we related the species richness, abundance and the spatial occurrence of lizards to the structure of the vegetation found on the coast of the state of Espírito Santo, southeastern Brazil, to determine whether habitat influe

23. Breeding system and pollination of Pleroma trichopodum DC. (Melastomataceae): a potential species for the restoration of Atlantic Forest in southern Brazil
ABSTRACT Plant-pollinator interactions and their reproductive implications are of central importance to the organization of plant populations and communities in restoration areas. We studied the breeding system and flower visitors of Pleroma trichopodum, a pioneer species of the Atlantic Forest. We attempted to answer three questions: (1) Is P. trichopodum d

24. Prevalence and correlates of insufficient physical activity in school adolescents in Peru
ABSTRACT OBJECTIVE To assess the prevalence and correlates of insufficient physical activity in adolescents in Peru. METHODS We used a self-administered questionnaire developed from Global school-based Student Health Survey to collect information from secondary school students in North Lima and Callao in 2015. We carried out Poisson regression with robust
