Metal accumulation and apoptosis in the alimentary canal of Lumbricus terrestris as a metal biomarker

Description : The chloragogenous tissue and the intestinal epithelium of adult earthworms, Lumbricus terrestris, sampled from sites with and without volcanic activity in the Azores were submitted to hematoxylin/eosin staining, autometallography and TUNEL-test in order to quantify the radial thickness of both tiss...

Chronic exposure to volcanic environments and chronic bronchitis incidence in the Azores, Portugal

Description : The village of Furnas, like other active volcanic areas in the world, exhibits high levels of hazardous gases. We aimed to investigate the existence of a possible association between chronic exposure to volcanic sulfur gases and chronic bronchitis. To investigate this, we used two populations, one e...

Altered inorganic composition of enamel and dentin in mice teeth chronically exposed to an enriched mineral environment at Furnas, São Miguel (Azores)

Description : Active volcanic environments pose a multifactorial stress challenge to local organisms, including the domestic mouse Mus musculus. Energy-dispersive X-ray microanalysis was used to determine the elemental composition of lower incisor enamel and dentin from Mus musculus inhabiting the hydrothermal fi...

Baseline Levels of Metals in Volcanic Soils of the Azores (Portugal)

Description : Data on metal concentrations present in the soils of the Azores (Portugal) are scarce. The goal of this study was to measure the current levels of several metals in the top horizon of soils of two areas, distinguishable by their volcanic activity and physical characteristics, in order to establish s...

Apoptosis, metallothionein, and bioavailable metals in domestic mice (Mus musculus L.) from a human-inhabited volcanic area

Description : The influence of extreme environments of volcanic origin over vertebrates and the cellular responses that these may give are almost unknown. The main objectives were to evaluate the exposure of mice to metals in the interior of houses of a small village settled inside a volcanic crater (Furnas, Azor...

A case of simultaneous hermaphroditism in the Azorean endemic limpet Patella candei gomesii (Mollusca: Patellogastropoda), a gonochoristic species

Description : A case of simultaneous hermaphroditism was observed in Patella candei gomesii, an Azorean endemic species, which has been considered a gonochoristic species. Here we show that simultaneous hermaphroditism can occur within the family Patellidae. , Copyright © 2007, Taylor & Francis. , CIRN/UAc; DRCT/Govern...
