The Role of Oxidative Stress in Periodontitis

Journal 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.

Exploring natural sunscreens: UVB protection and antioxidant properties in gadusol‐rich fish roes extracts

Photochemistry and Photobiology, EarlyView.
Gadusol‐rich extracts provide effective UVB protection and antioxidant activity in HaCaT cells and C. elegans, highlighting their potential as natural photochemoprotective agents for pharmaceutical and cosmetic applications. It also demonstrates remarkable in vitro antioxidant capacity and thermal stability over time.

β‐Secretase (BACE1) inhibition causes retinal pathology by vascular dysregulation and accumulation of age pigment

EMBO Molecular Medicine, 2012
β‐Secretase (BACE1) is a major drug target for combating Alzheimer's disease (AD). Here we show that BACE1−/− mice develop significant retinal pathology including retinal thinning, apoptosis, reduced retinal vascular density and an increase in the age ...

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

Periodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse

Experimental Physiology, EarlyView.
Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

Senolytics and exercise: Dual modalities for rejuvenating muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...

Alzheimer's Protection by PLCγ2 Compacts Plaques, Redistributes Microglia, and Protects Synapses in AppNL‐G‐F Mice

Glia, Volume 74, Issue 8, August 2026.
The Alzheimer's disease protective PLCG2 P522R variant protects against amyloid‐induced synapse loss independently of amyloid load, promotes increased plaque compaction, and is associated with enhanced microglial engagement with diffuse amyloid. ABSTRACT The Alzheimer's disease protective P522R PLCG2 coding variant (rs72824905) is downstream of TREM2 ...

ABCA4‐Associated Retinal Degeneration in 8 Families From the Three Provinces of Northeast China: Identification and Characterization of Potentially Novel Variants

Molecular Genetics &Genomic Medicine, Volume 14, Issue 7, July 2026.
This study reports the documented case of ABCA4‐associated early‐onset severe retinal dystrophy in China, broadens the mutational spectrum of ABCA4 in this population, and highlights distinct genotype–phenotype correlations that may inform clinical management and genetic counseling.
