Análise filogenética e implicações sistemáticas e evolutivas nos Cuculiformes (Aves) com base na osteologia, comportamento e ecologia

Têm-se notado vários estudos recentes em filogenia com os Cuculiformes, no entanto nestes trabalhos ainda há divergências. Apresenta-se aqui uma nova e ampla análise filogenética para os Cuculiformes com base em 250 caracteres da osteologia, comportamento e ecologia. Esta análise resultou em 18 cladogramas igualmente parcimoniosos (768 passos, IC = 0.4779, IR = 0.8080 e ICR = 0.3861). de acordo com o cladograma de consenso estrito se pode observar: a) o monofiletismo dos Cuculiformes; b) a ordem dividida em dois grupos: a) Coua/Carpococcyx e; b) demais cucos (Neomorphidae, (Crotophagidae, (Tapera/Dromoccoccyx, (Cuculidae))), no entanto a posição sistemática de Centropus é ambígua entre estes dois grandes grupos; c) os cucos terrestres basais e parafiléticos e os cucos arbóreos derivados e monofiléticos. Ainda, propõe-se que o comportamento de parasitar ninho tenha surgido duas vezes independentemente (uma em Tapera/Dromoccoccyx e outra dentro de Cuculidae).

Abordagem diagnóstica dos pacientes com suspeita de trombose venosa profunda dos membros inferiores

Deep venous thrombosis is a relatively common disease, which can present pulmonary embolism as a complication in its acute phase, and later the post-thrombotic syndrome. Thus, diagnosis should be made as soon as possible, in order to prevent or minimize such complications. Several studies have shown that the symptoms and the clinical signs are inaccurate for the deep venous thrombosis diagnosis and that complementary exams are necessary. As an attempt to simplify the patients' assessment, Well et al., in 1997, developed a clinical prediction index that combines symptoms, signs and risk factors for deep venous thrombosis and managed to make a simpler approach through an association of this index with the complementary exams. Phlebography has been considered the gold standard of complementary exams. However, since it is an invasive exam and thus subject to complications, other diagnostic methods were introduced aiming at making the diagnostic approach simpler and less invasive. Doppler ultrasound, duplex scan, impedance plethysmography, computed tomography, and blood tests such as the D-dimer are some of the available methods for assessing the patient with suspicion of deep venous thrombosis. Among them, duplex scan has shown excellent accuracy and it is currently widely accepted as the first choice test for approaching the patient with deep venous thrombosis. Several authors have suggested an association of diagnostic methods to simplify and make the assessment of such patients more cost-effective, leading to the introduction of a wide range of diagnostic strategies. The different diagnostic methods used for assessing deep venous thrombosis are discussed, as well as a review of the literature on the accuracy, advantages and disadvantages of these methods.

Os Répteis do Município de São Paulo: Diversidade e ecologia da fauna pretérita e atual

The reptile fauna in the municipality of São Paulo is well sampled due to intensive collection in the last 100 years. In the present work we provide a checklist of reptile species in São Paulo municipality based on preserved specimens in scientific collections. The reptile fauna was also characterized by three ecological parameters: habitat use, substrate use, and diet. We recorded a total of 97 reptile species (two turtles, one crocodilian, 19 lizards, seven amphisbaenians, and 68 snakes). Approximately 70% of the lizards and 40% of the snakes are typical of forest habitats of the Serra do Mar mountain range. Other squamates are typical of open formations that occur mainly on inland Cerrado habitats. All turtles and the crocodilian are associated to riparian habitats. Approximately 63% of the lizards are predominantly terrestrial, and the remaining species are arboreal. Most species of snakes are terrestrial (38%) or subterranean/criptozoic (25%) whereas a smaller proportion are arboreal (18%) or aquatic (9%). Lizards feed upon arthropods. Almost 50% of the snake species are specialized or feed mainly upon anuran amphibians. Other important items consumed by snakes are mammals (24%), lizards (18%), subterranean vertebrates (10%), and invertebrates (earthworms, mollusks and arthropods; 15%). A total of 51 reptile species have not been recorded for the last six years. Probably many of these species are extinct in the region due the intense local urbanization and habitat loss. The survey of species collected in São Paulo municipality and received in the Instituto Butantan in recent years allowed the identification of 10 lizards at least 42 snake species already occurring in the region. The high species richness of the original fauna seems related to the geographic location of the municipality, in a contact zone between forested areas of the Atlantic Forest (ombrophilous forest) and open formations (savannas, high-altitude grassland). Thus, the original habitat composition probably allowed sympatry among different species pools typical of both open and forested formations. The extant snake fauna recorded in the last three years indicates a higher loss of the species in open formations when compared to the forested areas.

Entrenamiento continuo vs. interválico corriendo en piscina profunda: Efectos sobre la salud de las mujeres obesas

Objectives. To search intermittent and continous trainning (IT and CT, respectively) effects through deep water running for the control and prevention of excessive body fat accumulation and improvement of quality of life. Methods. Experimental study composed by 30 women, aged between 34 to 58 years old, during 12 weeks, three sessions per week, 47 minutes each. Body composition, cardiorespiratory condition and Quality of Life by WHOQOL-Brief were considered. Student's and Wilcoxon's non parametric tests were applied at 5% significance level. Results. With the only exception for social domain of quality of life, all investigated variables revealed improvement in both groups for IT in comparison to CT. Conclusion. Deep water running contributes to body fat reduction, physical fitness evolution and improvement of WHOQOL-Brief domains, regardless of the trainning type conducted. © 2012 Revista Andaluza de Medicina del Deporte.
