13. Efeito do exercício físico durante a gravidez sobre o fluxo sanguíneo feto-placentário e o crescimento fetal : ensaio controlado e aleatorizado / Effect of exercise during pregnancy on the blood flow fetal-placental and fetal growth : randomized controlled trials
Introduction: Fetal growth has always been one of the major concerns regarding the practice of exercise during pregnancy, with discussions on whether the redistribution of fetoplacental blood flow during physical exercise and the bypass of blood from the viscera to the muscles could lead to transitory fetal hypoxia. Objective: To study the. E effect of super

14. Geographic variation in hairy dwarf porcupines of Coendou from eastern Brazil (Mammalia: Erethizontidae)
We evaluated geographic variation in New World porcupines of Coendou (Erethizontidae) from eastern Brazil by analyzing morphological data from museum specimens we identified as Coendou insidiosus and C. spinosus. Coendou insidiosus ranges from the states of Bahia to Espírito Santo, reaching the state of Minas Gerais in Brazil; C. spinosus extends from the s

15. Sistemas dinâmicos de eventos discretos com aplicação ao fluxo geodésico em superfícies hiperbólicas / Discrete event dynamical systems with application to the geodesic flow on hyperbolic surfaces
Neste trabalho apresentamos um método de descrição combinatorial para o fluxo geodesico sobre uma região hiperbólica compacta, tendo como objetivo associar a seqüências de codificação, parâmetros topologicos oriundos destas superfícies. Isto permite conjugar conceitos topologicos e combinatoriais oriundos das superfícies estudadas com conceitos d

16. Avaliação sensitiva orofacial, gustativa, olfativa e salivar em doentes com neuralgias trigeminais / Somesthetic, gustatory, olfactory function and salivary flow in patients with neuropathic trigeminal pain
Trigeminal postherpetic neuralgia (PHN), idiopathic trigeminal neuralgia (ITN) and burning mouth syndrome (BMS) are painful neuropathies with no clear signs about their causes. The objectives of this study were to determine somatosensory, olfactory, gustative and salivary characteristics of patients with PHN, ITN and BMS compared to controls. Twenty patients

17. Histomorphometric analysis of the repair process of autogenous bone grafts fixed at rat calvaria with cyanoacrylate
OBJECTIVE: The purpose of this study was to perform histological and histometric analyses of the repair process of autogenous bone grafts fixed at rat calvaria with ethyl-cyanoacrylate adhesive. MATERIAL AND METHODS: Thirty-two rats were divided into two groups (n=16), Group I - Control and Group II - Adhesive. Osteotomies were made at the right parietal bon

18. Inflammatory response, parasite load and AgNOR expression in ear skin of symptomatic and asymptomatic Leishmania (Leishmania) chagasi infected dogs
The skin has an important role in the transmission of visceral leishmaniasis (VL) as the infection pathway in dogs. To better characterize the inflammatory response of intact skin in VL, sixty infected dogs (30 symptomatic and 30 asymptomatic) and six non-infected controls were studied. Diagnosis of visceral leishmaniasis was confirmed by RIFI and ELISA; dir

19. Estudo da relação entre os diferentes graus de hipercontratilidade do corpo do esôfago e o refluxo gastroesofágico / Investigating the relationship between different degrees of hypercontractility body of the esophagus and gastroesophageal reflux
The "Nutcracker esophagus " (NE) is a disease of manometric diagnosis, described in 1977, characterized by hypercontractility esophageal body. In the 1990s, there were publications relating the NE to gastroesophageal reflux disease (GERD), which has since been the subject of controversy. Such controversy and a lack of studies evaluating reflux in less intens

20. Elections for Senator in Brazil and spent on campaign / EleiÃÃes para senador no Brasil e gastos em campanha
In most countries, financing of political campaigns is performed through the large business groups, which suggests that there is some set of interests embedded in their donations. In this sense, the effects of campaign spending on election outcomes have been widely investigated for various political systems all over the world with the aim to find empirical e

21. Área e discretude de representações / Area and discreteness of representations
Primeiramente, apresentamos uma introdução à geometria hiperbólica plana que pode ser útil, inclusive, para um principiante. A seguir, utilizando o conceito de "terremoto simples", descrevemos explicitamente, em termos de algumas coordenadas naturais, o espaço de Teichmüller T Hn de superfícies hiperelípticas. Esta descrição resulta simples: T Hn

22. Estudo comparativo da cicatrização entre os fios poliglecaprone, algodão e poliglactina em anastomoses de intestino delgado de cães / Polyglecaprone, cotton and polyglactin sutures in intestinal anastomoses of dogs, a comparative study
In this study was evaluate, macroscopically and microscopically, the healing process of intestinal anastomoses in dogs using polyglecaprone 25, polyglactin 910 and cotton sutures. Twenty mongrel dogs, weighting from 9 to 16 Kg were submitted, under general inhalatory anesthesia, to three small intestine anastomoses. The animals were divided into four groups,

23. Codigos esfericos em toros planares / Spherical codes on flat torus
Spherical codes in Euclidean spaces are finite sets of points on the surface of a multidimensional sphere and have been widely studied in connection with the signal transmission over a Gaussian channel. For this purpose one fundamental issue is to maximize the minimum distance between two code points, what is strongly related to the more general problem of s

24. Desenvolvimento psicológico e transtorno de déficit de atenção e hiperatividade (TDAH): a construção do pensamento operatório / Psychological development and Attention Deficit Hyperactitity Disorder (ADHD): the construction of operational thinking
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most prevalent disorders in childhood and adolescence. Recent research shows that, at least from a cognitive level, there are important differences in the development of children with ADHD when compared with children without any psychiatric diagnosis. This work aims to contribute to the field of r
