Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Efficacy of Fermented Brown Rice by Aspergillus oryzae (FBRA) in Ulcerative Colitis: A Double‐Blind Randomized Trial

JGH Open, Volume 10, Issue 10, October 2026.
ABSTRACT Background Ulcerative colitis (UC) is a diffuse, nonspecific inflammation of the colon of unknown cause. Basic and clinical studies suggest that UC may be ameliorated by dietary fiber intake. Fermented brown rice by Aspergillus oryzae (FBRA) is produced by fermenting brown rice and bran with A. oryzae. We aimed to evaluate the efficacy of FBRA

Environmental Pesticide Exposure in the Etiology of Pediatric Brain Tumors and Leukemia: A Scoping Review of Epidemiological Studies

International Journal of Cancer, Volume 159, Issue 6, Page 1360-1384, 15 September 2026.
ABSTRACT Pediatric cancer is a significant cause of morbidity and mortality in children. The etiologies of pediatric cancer are largely unknown, but environmental pesticide exposures are likely to contribute. Chronic low‐dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities.
