Article Synopsis
- ω-3 polyunsaturated fatty acids, especially docosahexaenoic acid (DHA), are vital for brain health, but excessive DHA can lead to oxidative stress in the brain.
- A study on male rats showed that a 10-week diet with high-DHA fish oil improved antioxidant defenses and reduced protein carbonylation in brain regions compared to oils with lower DHA levels.
- Findings revealed that the cerebellum is more affected by dietary fat composition than the cortex, suggesting that high DHA intake enhances the brain's ability to cope with oxidative damage.
Ocean acidification impact on the uptake of trace elements by mussels and their biochemical effects.

This study delves into the intricate interplay between ocean acidification (OA), metal bioaccumulation, and cellular responses using mussels (Mytilus galloprovincialis) as bioindicators. For this purpose, environmentally realistic concentrations of isotopically labelled metals (Cd, Cu, Ag, Ce) were added to investigate whether the OA increase would modify metal bioaccumulation and induce adverse effects at the cellular level. The study reveals that while certain elements like Cd and Ag might remain unaffected by OA, the bioavailability of Cu and Ce could potentially escalate, leading to amplified accumulation in marine organisms.
