Gadolinium Pollution—A Future Forward Perspective on Human and Environmental Impact

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1660-1670, March 2026.
ABSTRACT The widespread use of gadolinium‐based contrast agents (GBCAs) in magnetic resonance imaging (MRI) has been instrumental in enhancing diagnostic capabilities. However, the potential environmental and human health impacts of gadolinium pollution have become a growing concern.

Prokaryotic PfaB is a terminal acyltransferase that determines the final PUFA product

Protein Science, Volume 35, Issue 3, March 2026.
Abstract Omega‐3 polyunsaturated fatty acids (PUFAs) are essential for human health due to their numerous beneficial biological properties. These compounds are synthesized in marine bacteria and eukaryotic microalgae by PUFA megasynthases (Pfas), which are evolutionarily related to fatty acid synthases (FAS) and polyketide synthases (PKS). In FAS, PKS,

Assembly, growth and conductive properties of tellurium nanorods produced by Rhodococcus aetherivorans BCP1 [PDF]

, 2018
Tellurite (TeO32-) is a hazardous and toxic oxyanion for living organisms. However, several microorganisms can bioconvert TeO32- into the less toxic form of elemental tellurium (Te0).

Drug Delivery Systems for Resiquimod to Control Myeloid‐Derived Suppressor Cells in Cancer Immunotherapy

WIREs Nanomedicine and Nanobiotechnology, Volume 18, Issue 2, March/April 2026.
Myeloid‐derived suppressor cells (MDSCs) are key contributors to cancer immunotherapy failure and major targets in new therapeutic strategies. We highlight therapeutic approaches to counteract their immunosuppressive functions and discuss recent efforts to optimize drug delivery for controlling MDSCs, focusing on resiquimod as a representative drug ...

Physiological function and catalytic versatility of bacterial multihaem cytochromescinvolved in nitrogen and sulfur cycling [PDF]

, 2011
Bacterial MCCs (multihaem cytochromes c) represent widespread respiratory electron-transfer proteins. In addition, some of them convert substrates such as nitrite, hydroxylamine, nitric oxide, hydrazine, sulfite, thiosulfate or hydrogen peroxide. In many
