Lead (Pb) is commonly found in urban soils and can transfer to vegetables. This entails a health risk for consumers of garden crops. The increasing demand of gardening on urban soil linked to the population increase and concentration in urban areas induces an increase in the risk, as people could be forced to cultivate contaminated soils.

- - Bioaugmentation with Pseudomonas putida enhanced the ability of sunflowers to extract copper (Cu) from vineyard soils, increasing Cu concentration in roots by 93% and in shoots by 17%, while also boosting sunflower biomass by 30% to 60%.
- - The study focused on the mechanisms behind copper transfer from soil to plants, highlighting the role of siderophores, particularly pyoverdine (Pvd), which formed a 1:1 complex with Cu, aiding its mobilization and availability for the sunflowers.
- - Interestingly, carbonated soils did not enhance the mobilization of trace elements as expected, suggesting that further optimization could involve strategies to enhance the dissociation of the Pvd-C
Docosahexaenoic acid (DHA), the main member of the omega-3 essential fatty acid family, has been shown to reduce the invasion of the triple-negative breast cancer cell line MDA-MB-231, but the mechanism involved remains unclear. In the present study, a proteomic approach was used to define changes in protein expression induced by DHA. Proteins from crude membrane preparations of MDA-MB-231 cells treated with 100 µM DHA were separated by two-dimensional electrophoresis (2-DE) and differentially expressed proteins were identified using MALDI-TOF mass spectrometry.
