Nanoscale distribution of potentially toxic elements in seaweeds revealed by synchrotron X-ray fluorescence.

Assessing the impact of potentially toxic elements (PTEs) on coastal waters requires understanding their interaction with seaweeds, as they are foundational organisms in nearshore ecosystems. While seaweeds are known to accumulate PTEs, information on the mechanisms and locations of this accumulation is very limited. We employed synchrotron-based X-ray fluorescence (S-XRF) to map the distribution of various chemical elements at nanometric resolution in Fucus vesiculosus, a brown alga dominant in intertidal zones.

Proteomic analysis of endothelial cells and extracellular vesicles in response to indoxyl sulfate: Mechanisms of endothelial dysfunction in chronic kidney disease.

Aims: Cardiovascular pathology is the main cause of death in chronic kidney disease (CKD) patients. CKD is associated with the accumulation of uremic toxins in the bloodstream, and indoxyl sulfate (IS) is one of the most abundant uremic toxins found in the blood of CKD patients. We conducted an in vitro study to assess the mechanisms underlying the IS-induced endothelial dysfunction that could lead to cardiovascular diseases.

Spatial control of potato tuberization by the TCP transcription factor BRANCHED1b.

The control of carbon allocation, storage and usage is critical for plant growth and development and is exploited for both crop food production and CO capture. Potato tubers are natural carbon reserves in the form of starch that have evolved to allow propagation and survival over winter. They form from stolons, below ground, where they are protected from adverse environmental conditions and animal foraging.
