TL;DR: Analysis of molecular divergence compared with yeasts and metazoans reveals rapid rates of gene diversification in diatoms, and documents the presence of hundreds of genes from bacteria, likely to provide novel possibilities for metabolite management and for perception of environmental signals.

TL;DR: Au NPs were responsible of metallothionein induction, increased activities of catalase and superoxide dismutase, and of glutathione S-transferase by the three sizes of AuNPs indicating defense against oxidative stress, however, it must be underlined that these effects were observed at a dose much higher than expected in the environment.

TL;DR: A protocol that enables the simultaneous isolation of proteins and DNA from the red seaweed Palmaria palmata is described, based upon a specific form of hydrolysis using a mixture of cellulase and xylanase at different concentrations.

TL;DR: In the digestive gland, the most striking feature was the presence of individual or small aggregates 40 nm sized within the nuclei colocalized with DNA, and the perinuclear space from nuclei was enlarged in contaminated clams when compared to controls.

TL;DR: This protocol, using 2 steps, is based on a preliminary enzymatic digestion of cell wall with specific enzymes followed by centrifugation, allowing isolation of DNA on the pellet, providing a higher yield of DNA.
