Trace elements influence the hatching success and emergence of Caretta caretta and Chelonia mydas.

Trace elements from industrial, domestic and agricultural activities can be transferred into marine environments, affecting the survival of sea species. Due to their global distribution, sea turtles are recognized as indicators of ocean pollution. The aim of this work was to quantify Ba, Cd, Cr, Cu, Fe, Mn, Pb, Sr and Zn using inductively coupled plasma optical emission spectrometry (ICP-OES) in the eggs and offspring of Caretta caretta and Chelonia mydas from two important nesting beaches, Guanabara Beach, Anchieta, and Trindade/Martim Vaz Island, Espírito Santo, Brazil.

Site fidelity and movement of Chelonoidis carbonaria (Spix, 1824) (Testudinidae) in cocoa plantations in southeastern Brazil.

Red-footed Tortoises (Chelonoidis carbonaria Spix, 1824) raised as pets and voluntarily handed over to environmental officers by their owners or apprehended by officers represent a large contingent of animals that overfill triage centres in Brazil. There is no consensus on the fate of these animals, and their numbers continue growing. In this study, we evaluated the movement patterns of C.

Morphological variations and sexual dimorphism in Chelonoidis carbonaria (Spix, 1824) and Chelonoidis denticulata (Linnaeus, 1766) (Testudinidae).

Chelonoidis Dcarbonaria and C. denticulata are two tortoises which are widely distributed Brazil. Although they occur sympatrically in different areas, C.

Morphometric pattern in Caretta caretta (Linnaeus, 1758)(Cheloniidae) hatchlings from nests with different embryo development rates.

The geometric morphometric analysis of the shell of Caretta caretta hatchlings revealed that morphological variations may be related to incubation duration. Based on the overlapping of anatomical landmarks of the carapace and the plastron, it was possible to discriminate hatchlings from slow and fast developing clutches. Carapace and plastron of hatchlings from nests where incubation lasted less than 55 days are rounder as compared to the hatchlings from nests where incubation took 67 days.

Nesting ecology of Podocnemis expansa (Schweigger, 1812) and Podocnemis unifilis (Troschel, 1848) (Testudines, Podocnemididae) in the Javaés River, Brazil.

Nest site has influence on incubation duration and hatching success of two Neotropical turtles, the giant Amazon River turtle (Podocnemis expansa) and yellow-spotted side-neck turtle (Podocnemis unifilis--'Tracajá'). The 2000 and 2001 nesting seasons have been monitored at the Javaés River in Bananal Island, Brazil. Although they nest on the same beaches, there is a separation of the nesting areas of P unifilis and P.

ABPM in COPD patients with sleep desaturation.

Background: Sleep hypoxemia may change blood pressure by sympathetic activation. Few studies have analyzed blood pressure parameters in COPD patients who do not present sleep apnea, but do present sleep desaturation.

Objectives: To analyze blood pressure parameters in COPD patients with sleep desaturation not caused by apnea.

[The occurrence of rotaviruses and adenoviruses in children up to 11 years old without diarrheal symptomatology in Goiânia, Goiás].

Three hundred and eighty-five children without a diagnosis of diarrhoeal illness had faecal specimens collected in order to detect rotavirus infection. The survey was conducted in Goiânia city--central Brazil and the children aged 0-11 years old were recruited (268 in day care centers and 117 from a local outpatient clinic--Hospital Lucio Rebelo). Detection of rotavirus was done by polyacrylamide gel electrophoresis (PAGE-SDS), and 89 specimens were also analyzed by commercial enzyme immunoassays for rotavirus and adenovirus (EIARA).
