Lysosomal Membrane Stability in Mussels

Effects of the ‘Prestige’ oil spill on cellular biomarkers in intertidal mussels: results of the first year of studies

In November 2002 the tanker ‘Prestige’ sunk in front of the Galician coast (NW Iberian Peninsula). As a result, >60 000 t of heavy fuel oil leaked into the sea, affecting >1000 km of coastline. In order to assess the effects of the oil spill on coastal ecosystems, mussels Mytilus galloprovincialis were sampled (April, July and September 2003) in 17 locations along the Galician and Bay of Biscay...

Evaluation of marine water quality along North-Eastern Adriatic coast based on lysosomal membrane stability in mussels Mytilus galloprovincialis Lam. - A long term study

Lysosomal membrane stability and respiration rate in zebra mussel (Dreissena polymorpha Pallas, 1771) as biomarkers for ex situ heavy metal exposure

Background and purpose: In the current study we aimed to investigate the lysosomal membrane stability in haemocytes of the invasive mollusk zebra mussel (Dreissena polymorpha Pallas, 1771) by applying the neutral red retention assay (NRRA), as well as changes in the respiration rate and survival under acute heavy metal exposure. Materials and methods: The mussels were treated with different dec...

Transcriptional Response of the Mussel Mytilus galloprovincialis (Lam.) following Exposure to Heat Stress and Copper

Global warming is a major factor that may affect biological organization, especially in marine ecosystems and in coastal areas that are particularly subject to anthropogenic pollution. We evaluated the effects of simultaneous changes in temperature and copper concentrations on lysosomal membrane stability (N-acetyl-hexosaminidase activity) and malondialdehyde accumulation (MDA) in the gill of t...

Effect of environmental contaminants on the health of Mytilus edulis from Puget Sound, Washington, USA. I. Cytochemical measures of lysosomal responses in the digestive cells using automatic image analysis

Lysosomal responses in the digestive cells of Mytilus eduljs from 9 sites in Puget Sound, Washington. USA, with varying degrees of sediment contamination were measured using automatic image analysis. Mussels from urban-associated sltes (areas with elevated sediment concentration of anthropogenic contaminants such as PAHs, PCBs. DDTs, and toxic elements) showed pathological changes in the lysoso...
