Move beyond free radical theory of aging

open access: yesiMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

open access: yesInterdisciplinary Medicine, EarlyView.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

open access: yesJournal of Intelligent Medicine, EarlyView.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Peri‐implant hypoxia as a potential barrier against ferroptotic mechanisms during peri‐implant diseases: A cross‐sectional study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Hypoxia modulates inflammation and oxidative stress through hypoxia‐inducible factor‐1α (HIF‐1α). Ferroptosis, an iron‐dependent cell death process, is regulated by glutathione peroxidase‐4 (GPX4) and involves lipid peroxidation markers like malondialdehyde (MDA).

Nanoemulsions for Skin Delivery of Essential Oils: A Systematic Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Essential oils (EOs) are recognized for their multiple health benefits. However, their high volatility, low stability, and limited water solubility limit their effective application. This systematic review aims to assess the use of nanoemulsions as delivery systems for the topical administration of EOs, highlighting their efficacy, safety, and

Bridging Psychological Stress and Skin Cellular Aging: Flavonoids as a Dual‐Action Therapeutic Strategy

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Psychological stress (or simply “stress”) is a major contributor to chronic disease worldwide, affecting 35% of the global population, including younger generations. Furthermore, it plays a significant role in human premature aging; hence, its detrimental effects on people's health compel us to comprehend and control the ways in which ...

Advances in Elemene Nanodelivery Systems: From Material Design to Disease Treatment

open access: yesRare Metals, EarlyView.
ABSTRACT Elemene (ELE) is a bioactive sesquiterpenoid extracted from traditional Chinese herbs, demonstrating broad‐spectrum antitumor, anti‐inflammatory, and analgesic properties with significant therapeutic potential. However, its clinical utility is constrained by inherent physicochemical limitations, including volatility and hydrophobicity, which ...

Exploring Interactive Effects of Arsenic and Selenium Exposure on Larval Zebrafish (Danio rerio)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Arsenic contamination in aquatic ecosystems is a major environmental concern. Selenium (Se) helps mitigate oxidative stress and hence could reduce the toxic effects of arsenic. However, Se can also be toxic at high concentrations. Given that these metalloids commonly co‐occur in the environment, there is a pressing need for further research ...
