Bacterial Extracellular Vesicles in Biomedical Research and Clinical Translation

open access: yesMicrobial Biotechnology, Volume 19, Issue 4, April 2026.
Bacterial membrane vesicle biomedical applications. ABSTRACT Bacterial Extracellular Vesicles (bEVs) are lipid (single‐ or double‐bilayer) nanostructures secreted by virtually all bacteria that play fundamental roles in intercellular communication and have emerged as powerful, multifunctional tools in biomedicine. Their intrinsic ability to encapsulate

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 433-447, April 2026.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...
