Subject grounding to reduce electromagnetic interference for MRI scanners operating in unshielded environments. [PDF]

Magn Reson Med
Abstract Purpose Portable low‐field (<0.1T) MRI is increasingly used for point‐of‐care imaging, but electromagnetic interference (EMI) presents a significant challenge, especially in unshielded environments. EMI can degrade image quality and compromise diagnostic utility.

Subcellular Mechanisms of Se(IV) Reduction in Stenotrophomonas bentonitica: Linking Environmental Detoxification and Antimicrobial Activity of Se Nanostructures Within a Circular Economy Framework. [PDF]

Microb Biotechnol
Stenotrophomonas bentonitica reduces Se(IV) via compartment‐specific pathways in the cytoplasm and membrane, yielding amorphous SeNPs coated with a protein‐rich organic corona. Biogenic SeNPs trigger strain‐specific toxicity: ROS‐mediated oxidative and genotoxic stress in Escherichia coli, and early membrane disruption in Staphylococcus aureus ...
