Glutathione-S-transferase activity of Fucus spp. as a biomarker of environmental contamination.
TLDR
The objective of this study was to investigate the potential of glutathione-S-transferase (GST) activity of several Fucus species to discriminate sites with different contamination levels along the Portuguese Northwestern coast, between the Minho river estuary and the Aveiro's Lagoon, as an environmental biomarker.About:

Biochemical responses of the marine mussel Mytilus galloprovincialis to petrochemical environmental contamination along the North-western coast of Portugal
TL;DR: The redundancy analysis used to perform the integrated analysis of the data showed a clear separation of the sampling sites in three different assemblages, which are in agreement with the PAHs levels found in mussels tissues.

Yes, caffeine, ibuprofen, carbamazepine, novobiocin and tamoxifen have an effect on Corbicula fluminea (Müller, 1774)
TL;DR: LMS, responses from phase I and II enzymatic activity, oxidative stress, and biomarker of effect represent important ecotoxicological information, and will provide a useful reference for the assessment of selected drugs and the effects which these compounds may have on aquatic invertebrates, using C. fluminea as a bioindicator species.

Subtidal macrozoobenthic assemblages along the River Minho estuarine gradient (north‐west Iberian Peninsula)
TL;DR: The community composition and spatial distribution of the macrobenthic fauna in relation to abiotic factors was investigated at 20 sites along the River Minho estuarine gradient, in the north-west Iberian Peninsula.

TL;DR: Overall, the present findings suggest that COE exposure led to increased internal PAH burden, genetic damage, oxidative stress, and GST activity and the consequences of the changes in these biomarkers, such as risk of cancer, warrant further investigations.

TL;DR: The results indicated that the battery of biomarkers used in this study seems to be a useful tool to distinguish between different types of environmental contamination in estuarine systems, and that P. microps is a suitable species to be used as bioindicator.

A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding
TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.

Plant glutathione S-transferases: enzymes with multiple functions in sickness and in health.
TL;DR: The role of GSTs in metabolism is unclear, although their complex regulation by environmental stimuli implies that they have important protective functions and might also have non-catalytic roles as carriers for phytochemicals.

Evidence for glutathione peroxidase activities in cultured plant cells
TL;DR: Extracts from cultured plant cells of spinach, maize and sycamore and from Lemna plants contain detectable glutathione peroxidase activity, using either hydrogen peroxide or t-butyl hydroperoxide as substrates.

The occurrence and cellular significance of physodes in brown algae
TL;DR: The biogenesis and the role of physodes in brown algal cells and thalli are discussed andPhlorotannins, packaged within membrane-bound physodes, appear to play multiple roles in brown algae, both at the cellular and at the organismal level.
