Trace metals and over-expression of metallothioneins in bladder tumoral lesions: a case-control study
Description :
Abstract
Background
Previous studies have provided some evidence of a possible association between cancer and metallothioneins. Whether this relates to an exposure to carcinogenic metals remains unclear.
Methods
In order to examine the association between the expressio...

Description :
Soil tillage influences water erosion, and consequently, losses of calcium, magnesium and organic carbon in surface runoff. Nutrients and organic carbon are transported by surface runoff in particulate form, adsorbed to soil colloids or soluble in water, depending on the soil tillage system. This st...

Description :
Whether the radial thickness (RT) of the chloragogenous tissue and intestinal epithelium of earthworms (Lumbricus terrestris) reflects the bioavailability of metals in soils was investigated in two areas, one with active volcanism (Furnas) and another with no volcanic activity since 3 million years ...

Description :
Cellular biomarkers of exposure and biological effects were measured in digestive gland of snails (Physa acuta) sampled in sites with 12 andwithout active volcanismin SãoMiguel Island (Azores).Metal content in digestive cell lysosomeswas determined by image analysis 13 after autometallography (AMG) ...

Reproductive cycle of the rissoid Alvania mediolittoralis Gofas, 1989 (Mollusca, Gastropoda) at São Miguel Island (Azores, Portugal)
Description :
The reproductive cycle of an Alvania species is studied for first time. Alvania mediolittoralis Gofas, 1989 is an endemic Azorean rissoid very common in sheltered places and particularly abundant among the algal turf covering the lower half of the intertidal and upper subtidal rocky shores. This spe...

Description :
Whether volcanic environments pose a risk in cancer incidence is unknown. We investigated this question in two populations, one from an area with active manifestations of volcanism (Furnas) and another from an area without volcanic activity since 3 million years ago (Santa Maria), both in Azores.
