Mechanisms of Antioxidant Action: The Antifatigue Mechanism of Nitrosamines

, 1984
1. The present studies have shown that N-nitrosamines derived from the more active diarylamine antifatigue agents are considerably more effective as antifatigue agents than the parent amines when they are predispersed into rubber on an open mill ...

Generation of Probiotic‐Based Multifunctional Hydrogels Capable of Carrying Oxygen and Anti‐Inflammatory Drugs and Their Effect on Cell Viability Under Hypoxic Conditions

Journal of Biomedical Materials Research Part A, Volume 114, Issue 10, October 2026.
ABSTRACT Hypoxia and chronic inflammation have an interdependent relationship, as they stimulate each other. Under inflammation, hypoxia occurs in tissues and under hypoxia, transcription factors induce overproduction of pro‐inflammatory cytokines, causing the chronic inflammatory process.

Gastrointestinal Microbiome Dysbiosis in Cancer Development: Mechanisms and Biomarker Potential

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Dysbiosis of the gastrointestinal microbiome plays a role in carcinogenesis by inducing chronic inflammation, DNA damage, and activation of signaling pathways such as NF‐κB, STAT3, and Wnt/β‐catenin. Microorganisms such as Helicobacter pylori, Fusobacterium nucleatum, and Bacteroides fragilis promote the development of gastrointestinal tumors through ...
