Protracted Oxidative Alterations in the Mechanism of Hematopoietic Acute Radiation Syndrome

Antioxidants, 2015
The biological effects of high-dose total body ionizing irradiation [(thereafter, irradiation (IR)] are attributed to primary oxidative breakage of biomolecule targets, mitotic, apoptotic and necrotic cell death in the dose-limiting tissues, clastogenic ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

A Lavandula angustifolia flower extract and dipeptide‐4 blend modulates oxidative, glycative, autophagic and circadian pathways in human skin models

International Journal of Cosmetic Science, EarlyView.
The blend enhanced antioxidation, anti‐glycation, autophagy and circadian regulation in cell and skin models. Key markers included mitochondrial ROS, γ‐H2AX, AGEs, ATP, melatonin, LC3 and SOD. Significant improvements were visualized via fluorescence and quantified with statistical markers.
