We analyzed phytoplankton biodiversity trends in a 52 year (1967-2018) monitoring time-series from the archipelago of Helsinki, Gulf of Finland, the Baltic Sea. The community ordination revealed strong ordering of samples along the time axis (generalized additive model-gam fit: = 0.9).

We carried out a mesocosm experiment over 15 days to test the effect of this on the planktonic ecosystem. The experiment was set up in 2.

- Climate change is expected to increase brownification in coastal seas, leading to more runoff of organic matter and potentially impacting the planktonic ecosystem.
- A 15-day mesocosm experiment examined the effects of different nutrient treatments on phytoplankton, finding that added inorganic nutrients led to a bloom, but did not reduce primary production, despite expected changes.
- Brownification resulted in a shift towards smaller phytoplankton species, suggesting potential changes in carbon cycling and export processes in the marine environment.
Chronic oxidative stress eventually leads to protein aggregation in combination with impaired autophagy, which has been observed in age-related macular degeneration. We have previously shown an effective age-related macular degeneration disease model in mice with nuclear factor-erythroid 2-related factor-2 (NFE2L2) knockout. We have also shown pinosylvin, a polyphenol abundant in bark waste, to increase human retinal pigment epithelium cell viability .

We categorized ALF by organ systems and investigated correlations with the vital signs subsequently observed by the RRT and associations with mortality.
Methods: International, multicentre, retrospective cohort study including adult RRT patients without treatment limitations in 2017-2018 in one Australian and two Finnish tertiary hospitals.
