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, EarlyView.
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 ...

The Role of Oxidative Stress in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Multi‐Omics Signatures of Periodontitis and Periodontal Therapy on the Oral and Gut Microbiome

open access: yesJournal of Periodontal Research, EarlyView.
This multi‐omics study integrates shotgun metagenomics and NMR metabolomics to reveal coordinated microbial and metabolic signatures of periodontitis across the oral–gut axis. Non‐surgical periodontal therapy partially restored ecological and functional balance, supporting oral health as a modifiable driver of systemic microbial homeostasis.
