Records of breeding in Wilson's Plover Charadrius wilsonia with new localities for Brazil / Registros da reprodução de Charadrius wilsonia, com novas ocorrências para o Brasil

Wilson's Plover, Charadrius wilsonia, is widely distributed in coastal areas of the Americas. This report presents the first record of breeding in this species on Coroa do Avião Island, on the coast of Pernambuco, and in the estuary of the Cardoso and Camurupim rivers, on the coast of Piauí, in northeastern Brazil, extending the known area of reproduction of this species in this region. One breeding pair was observed on October 29th 2014 on Coroa do Avião Island, and a second pair was recorded on April 6th 2016 in the Cardoso/Camurupim estuary on the Piauí coast. Both the male and the female contributed to the incubation of the eggs. The nest on Coroa do Avião island was camouflaged by the local vegetation, but despite this, the eggs were attacked by a predator. Possible predators observed on the island included Caracara plancus and domestic cats and dogs.(AU)

Physical fitness and academic performance in youth: A systematic review.

Physical fitness (PF) is a construct of health- and skill-related attributes which have been associated with academic performance (AP) in youth. This study aimed to review the scientific evidence on the association among components of PF and AP in children and adolescents. A systematic review of articles using databases PubMed/Medline, ERIC, LILACS, SciELO, and Web of Science was undertaken. Cross-sectional and longitudinal studies examining the association between at least one component of PF and AP in children and adolescents, published between 1990 and June 2016, were included. Independent extraction of articles was carried out by the two authors using predefined data fields. From a total of 45 studies included, 25 report a positive association between components of PF with AP and 20 describe a single association between cardiorespiratory fitness (CRF) and AP. According to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines: 12 were classified as low, 32 as medium risk, and 1 as high risk of bias. Thirty-one studies reported a positive association between AP and CRF, six studies with muscular strength, three studies with flexibility, and seven studies reported a positive association between clustered of PF components and AP. The magnitude of the associations is weak to moderate (ß = 0.10-0.42 and odds = 1.01-4.14). There is strong evidence for a positive association between CRF and cluster of PF with AP in cross-sectional studies; and evidence from longitudinal studies for a positive association between cluster of PF and AP; the relationship between muscular strength and flexibility with AP remains uncertain.

A morphological and functional study of the cavo-hepatic junction in the human.

The authors studied the morphological and structural aspects of the junctions between the hepatic veins and the inferior vena cava. The study was carried out on 20 specimens obtained from adult cadavers of both sexes, fixed in 10% formaldehyde solution. The hepatic veins with their junctions on the inferior vena cava were isolated. Then a macroscopic analysis of the openings of the hepatic veins into the inferior vena cava was performed. Part of this material was embedded in paraffin, submitted to serial sectioning and stained with Azan's trichrome and resorcin-fuchsin. Three hepatic veins were observed in all cases: right, left and the middle. In 20% of the cases the middle hepatic vein opens directly into the inferior vena cava. The hepatic vein openings are supported by two pillars inferiorly united through a semilunar fold. The hepatic vein wall is greatly thickened at the level of its junction with the inferior vena cava, showing a large amount of muscular and collagenous fibers. These bundles constitute a sphincter-like formation which may play a physiological role in the control of the hepatic circulation.

Esquistossomose murina esperimental: estudo imunohistoquímicos das células ganglionares mioentéricas / Experimental murine Schistosomiasis: an immunohistochemical study of the ganglionic myoenteric cells

Para estudar a influência do processo granulomatoso esquistossomóticosobre as células ganglionares mioentéricas, foram utilizados 30 camundongos albinos Swiss infectadoscom 50 cercárias da cepa SLM do S. mansoni.O grupo controle foi constituído por dez animais näo infectados. Após sessenta dias de infecçäo, cortes histológicos do intestino delgadocorados por hematoxilina-eosina e P.A.S. demonstraram granulomas periovulares em todas as camadas da parede intestinal. Através do método imunohistoquímico indireto, usando-se a enolase neurônio-específica como marcador, observou-se desorganizaçäo do plexo mioentêrico em áreas contendo granulomas. Além disso, ocorreu rarefaçäo das estaçöes ganglionares, com aparente destruiçäo de células neuronais. A possível contribuiçäo dessas alteraçöes para a sintomatologia da esquistossomose humana é avaliada
