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.

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.

Which hair loss supplements actually work?

Researchers compare the effectiveness and safety of multiple dietary supplements for hair loss.

Clear aligners protect oral microbiome better than fixed braces

Researchers compare the effects of clear aligners and fixed appliances on oral microbiota and oxidative stress in the oral cavity.

$Study identifies Apex1 as a redox-regulated driver of fracture repair$

Study identifies Apex1 as a redox-regulated driver of fracture repair

Bone fractures usually heal efficiently, but in some patients this process fails, causing nonunion. A recent study identifies Apex1 as a redox-regulated driver of fracture repair.

Research uncovers why certain brain cells are more resilient to tau protein buildup

New research by UCLA Health and UC San Francisco has uncovered why certain brain cells are more resilient than others to the buildup of a toxic protein that is a hallmark of Alzheimer's disease and related dementias, potentially leading to new targets for therapies or treatments.

Brain protein CUL5 protects neurons by clearing toxic tau clumps

Researchers at UC San Francisco have identified a hazardous waste collector in the brain that disposes of the toxic clumps of tau protein that can lead to dementia.

Air pollution, not diet, shows the strongest link to poorer concentration in schoolgirls

This cross-sectional study of 300 school-aged girls in Tehran found that higher air pollution exposure was consistently associated with poorer concentration, while dietary antioxidant capacity showed weaker, model-dependent links to attention. No significant associations or interactions were observed for short-term memory, highlighting pollution exposure as the dominant factor influencing attentional performance.

New nanomaterial kills cancer cells via oxidative stress

Scientists at Oregon State University have developed a new nanomaterial that triggers a pair of chemical reactions inside cancer cells, killing the cells via oxidative stress while leaving healthy tissues alone.

New peptide targets the root causes of recurring seizures

New study suggests that an experimental peptide developed at the Hebrew University may reduce recurring seizures and support brain function by targeting underlying oxidative stress and inflammation processes linked to epilepsy.

Prenatal exposure to pollution impacts infant cognitive development

The prenatal period is a critical window for brain development, yet few studies have examined the impact of air pollution exposure during pregnancy on child cognition.

KAIST proposes novel strategy for multifactorial Alzheimer's treatment

Conventional treatments of Alzheimer's disease, one of the most common forms of dementia, have been largely focused on targeting individual pathological features.

Wildfire smoke significantly raises stroke risk among older adults

People exposed to wildfire smoke have a higher risk of suffering a stroke, according to research published in the European Heart Journal today (Tuesday).

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

Unraveling liver injury mechanisms in familial hypobetalipoproteinemia

Familial Hypobetalipoproteinemia (FHBL), caused by variants in the apolipoprotein B (APOB) gene, is a rare autosomal co-dominant monogenic disorder characterized by lifelong low plasma levels of total cholesterol, low-density lipoprotein cholesterol (LDL-C), and APOB.

Dual-responsive nanodelivery system enhances immunotherapy efficacy in metastatic bladder cancer

Metastatic urothelial carcinoma has a poor prognosis: ~50% of muscle-invasive bladder cancer progresses to metastasis, and the 5-year survival for advanced/metastatic disease is <10%.
