Bisphenol A alters transcript levels of biomarker genes for major depressive disorder

Major depressive disorder is a moderately heritable disorder characterized by one or more major depressive episodes. Laboratory tests to suport MDD diagnosis are not available. Diagnosis and treatment are based on various signs and symptoms not always fitting into strict diagnostic categories. Research for biological markers of neuropsychiatric disorders has been a challenge.

Efeitos do xenoestrógeneo Bisfenol A no envelhecimento celular

O Bisphenol A (BPA) é um xenoestrógeneo sintético capaz de ativar diversas vias de sinalização associadas a estrogénios. Este composto é utilizado na produção de plástico e das resinas de cola Epoxy, encontrando-se presente numa grande variedade de produtos para consumo humano. Consequentemente a exposição humana ao BPA é considerada generalizada e contínua. Estudos epidemiológicos verificaram correlação entre níveis elevados de BPA na urina e patogénese de doenças associadas ao envelhecimento celular como a aterosclerose. Neste estudo foram avaliados os efeitos da exposição prolongada ao BPA de concentrações encontradas em amostras biológicas humanas associadas a exposição ambiental e ocupacional, nomeadamente 10 ng/mL e 1 μg/ml.

Upper crustal structure of Madeira Island revealed from ambient noise tomography

We present the first image of the Madeira upper crustal structure, using ambient seismic noise tomography. 16 months of ambient noise, recorded in a dense network of 26 seismometers deployed across Madeira, allowed reconstructing Rayleigh wave Green's functions between receivers. Dispersion analysis was performed in the short period band from 1.0 to 4.0 s. Group velocity measurements were regionalized to obtain 20 tomographic images, with a lateral resolution of 2.0 km in central Madeira. Afterwards, the dispersion curves, extracted from each cell of the 2D group velocity maps, were inverted as a function of depth to obtain a 3D shear wave velocity model of the upper crust, from the surface to a depth of 2.0 km. The obtained 3D velocity model reveals features throughout the island that correlates well with surface geology and island evolution. (C) 2015 Elsevier B.V. All rights reserved.
