Oxidative Stress News and Research

RSS

Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Polyploidy-induced senescence may influence aging and cancer risk

A new editorial was published in Volume 18 of Aging-US on February 8, 2026, titled "Polyploidy-induced senescence: Linking development, differentiation, repair, and (possibly) cancer?"

Extreme endurance exercise pushes red blood cells toward accelerated aging

Extreme endurance running damages red blood cells in ways that may affect their ability to function properly, according to a study published in the American Society of Hematology's journal Blood Red Cells & Iron.

Can GLP-1 drugs slow neurodegeneration? New review finds promising signals but limited clinical proof

This review examines how GLP-1 receptor agonists may influence neurodegenerative disease biology through metabolic, inflammatory, mitochondrial, and proteostasis pathways. Evidence from mechanistic, preclinical, and early clinical studies suggests potential neuroprotective effects, but definitive disease-modifying benefit remains unproven.

Mask-wearing during COVID-19 may have reduced heart attack risk triggered by air pollution

Researchers at Kumamoto University have discovered that behavioral changes during the COVID-19 pandemic-particularly widespread mask-wearing-may have reduced the risk of certain types of heart attacks triggered by air pollution.

Do cocoa flavanols influence heart and fatty liver risk factors?

A recent Nutrients review examined whether cocoa-rich dark chocolate influences cardiovascular and metabolic dysfunction-associated steatotic liver disease risk factors through antioxidant, anti-inflammatory, and endothelial effects. Evidence suggests modest improvements in biomarkers, but most data come from short-term studies, so definitive clinical benefits remain unproven.

Unlocking the potential of phytochemicals in rheumatoid arthritis treatment

Announcing a new article publication for BIO Integration journal. In recent years, phytochemicals and medicinal plants have increasingly been used to treat autoimmune diseases, such as rheumatoid arthritis (RA).

Synergistic drug pair shows promise for spinal cord injury recovery

Spinal cord injury remains one of the most challenging neurological conditions to treat, largely because damage continues to worsen long after the initial trauma.

Air pollution increases physical disability progression in older adults

Long-term air pollution exposure is associated with faster progression of disability in older adults, highlighting critical public health implications.

Eating more plant-based foods may lower breast cancer risk, major international study indicates

Greater adherence to healthful plant-based dietary patterns was associated with lower breast cancer incidence and reduced all-cause mortality among women with breast cancer in large prospective cohorts. Specific micronutrients showed differential associations with cancer risk and survival, though findings remain observational and not causal.

Role of food nutrients in reducing oxidative stress linked to micro- and nanoplastics

This narrative review examines how micro- and nanoplastics may contribute to oxidative stress, inflammation, and metabolic dysfunction, including potential links with diabetes. It highlights plant-derived nutrients that activate the Nrf2 pathway as a possible strategy to enhance cellular stress resilience, although most evidence remains preclinical.

Study examines the relationship between leukocyte telomere length and age-related cataract

Cataracts remain the leading cause of blindness worldwide among adults over 50, despite major advances in surgical treatment.

Can hot baths lower high blood pressure?

A review highlights hot water immersion's potential in lowering blood pressure, emphasizing it as an adjunct therapy alongside traditional treatments.

Brief oxidative stress promotes brain repair after injury

Oxidative stress is a direct consequence of an excess in the body of so-called "free radicals" – reactive, unstable molecules that contain oxygen.

Newly identified protein interaction fine-tunes cellular stress responses

Cornell researchers have discovered a new way cells regulate how they respond to stress, identifying an interaction between two proteins that helps keep a critical cellular recycling system in balance.

Study reveals DNA methylation score that better detects alcohol intake than standard biomarkers

A Mediterranean cohort study evaluated a DNA methylation biomarker of alcohol intake and compared it with conventional indicators such as GGT. The epigenomic score correlated with alcohol exposure, linked to telomere shortening and epigenetic aging markers, but findings remain observational and population-specific.

Burn pit particles trigger lung inflammation through immune activation

A new study from National Jewish Health helps explain how exposure to burn pit smoke and desert dust may damage the lungs of military service members deployed to regions such as Afghanistan and Iraq.

Too many antioxidants may negatively affect future offspring

Antioxidants have been marketed as miracle supplements, touted for preventing chronic diseases and cancers; treating COPD and dementia; and slowing aging.

Metformin linked to lower odds of intermediate macular degeneration in people with diabetes

A five-year image-based study in people with type 2 diabetes found metformin use was associated with lower odds of developing intermediate age-related macular degeneration. The observational findings suggest a potential protective link but do not establish causation and warrant prospective clinical trials.

IVF study finds shorter insemination protects embryo availability without harming success

Short-term sperm–oocyte co-incubation during IVF cycles with only one or two retrieved oocytes produced cumulative live birth rates comparable to conventional overnight insemination. It also improved fertilisation metrics and reduced cancellation or no-embryo cycles, suggesting practical laboratory advantages without improving overall live birth probability.
