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.

Immune and metabolic shifts drive acute pancreatitis into chronic disease

Pancreatitis is clinically classified into acute pancreatitis (AP) and chronic pancreatitis (CP). Most patients with AP recover without residual pancreatic dysfunction; a subset develops recurrent AP, and only selected high-risk individuals-particularly those with ongoing etiological exposure, genetic susceptibility, or severe necrotizing disease-progress to CP.

Replacement PFAS chemical still harms developing zebrafish embryos

Publishing in the Journal of Hazardous Materials Advances, researchers from Kyushu University used zebrafish embryos to study the health effects of the PFAS called PFBS (Perfluorobutanesulfonic acid), a substitute PFAS thought to be safer than traditional compounds.

Omega-3 supplements show surprising effects on blood pressure

Findings suggest omega-3 supplements improve blood pressure and inflammatory biomarkers in hypertensive patients, indicating potential therapeutic benefits.

Could eating more mushrooms help protect your brain as you age?

A review of existing research suggests that ergothioneine, a natural antioxidant found primarily in mushrooms, may protect brain cells against oxidative stress, inflammation, and damage associated with Alzheimer's and Parkinson's diseases. Although laboratory and animal studies show promising neuroprotective effects, human evidence remains limited, and larger clinical trials are needed to determine whether supplementation can prevent or slow neurodegeneration.

New review outlines role of extracellular vesicles in cancer and aging

A new review was published in Volume 13 of Oncoscience on September 30, 2026, titled "Extracellular vesicles in health, aging and disease."

Metal fumes, drinking habits and dementia: What a new study found

This study examines how workplace chemicals and lifestyle habits may influence Lewy body dementia risk, revealing potential sex differences in exposure effects.

Hidden genetic differences in gut bacteria may hold clues to aging

Researchers analyzed approximately 12.8 million gut microbial genetic variants in 10,781 individuals across six cohorts, identifying 940 independent associations with 69 human health characteristics and environmental exposures. Nearly two-thirds of these associations were not accompanied by significant differences in bacterial species abundance, suggesting that microbial genetics can reveal relationships overlooked by conventional microbiome analyses, although causality remains unproven.

New nanovesicle therapy shows promise for treating alcohol-related liver disease

Alcohol-related liver disease (ALD) is characterized by hepatocellular injury, oxidative stress, inflammation, and extracellular matrix remodeling, yet effective therapies remain limited.

DHA improves autism-like behaviors in a preclinical rat study

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition marked by social and communication difficulties and repetitive behaviors.

Natural plant extract reduces cisplatin-induced kidney injury in mice

Acute kidney injury is common in hospitalized patients and rises sharply in intensive care, yet treatment options remain largely supportive.

Spaceflight research opens new avenues for studying rare pediatric diseases

Earth-based hiPSC models have transformed disease research but remain limited by cellular immaturity, a strong reliance on glycolysis rather than oxidative phosphorylation (OXPHOS), and incomplete tissue architecture.

Can pregnancy leave a lasting mark on biological aging?

A review examines how pregnancy spacing affects maternal aging, proposing that insufficient recovery may lead to cumulative biological aging and health risks.

Targeting EGFR signaling to reduce mucus overproduction in lung diseases

Airway mucus is part of innate lung defense, but when production overwhelms clearance, it obstructs airflow and worsens disease.

Eating walnuts was linked to higher IgG levels, but what does that mean for health?

A two-year randomized trial involving 474 older adults found that daily consumption of 30–60 grams of walnuts was associated with 6% higher total serum IgG concentrations compared with a control diet, with an 11% difference observed among US participants. Walnut consumption did not significantly affect IgM, MDA-LDL or MDA-LDL-specific antibodies, and whether the modest IgG difference has meaningful cardiovascular benefits remains unknown.

Mayo Clinic enters new medical era with precure research

Mayo Clinic researchers are uncovering the earliest shifts in disease biology - long before symptoms appear - revealing how disease takes root and opening new possibilities to identify, predict and potentially prevent disease before symptoms develop.

Worried nuts will cause weight gain? A large review puts that concern in perspective

A systematic review and meta-analysis of randomized trials found that eating nuts modestly reduced body fat and improved cholesterol levels without significantly changing body weight. The review did not establish that nuts rich in monounsaturated fats offered greater body-composition benefits than those rich in polyunsaturated fats.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

Researchers tested an unexpected addition to vaginal treatment: oxygen

Researchers investigated the effects of topical vaginal oxygen treatment, alone or combined with antimicrobials, on the vaginal microbiota of 22 women with bacterial vaginosis or vaginitis. The combined treatment reduced the relative abundance of strict anaerobes and increased Lactobacillus abundance, but the absence of an antimicrobial-only control group prevented researchers from establishing whether oxygen contributed independently to these changes.

Ketones may change sleep patterns, but not always for the better

Researchers reviewed animal and human studies and found that ketone bodies may affect sleep stages through energy metabolism and cellular signaling, with the clearest direct evidence involving acetoacetate in mice. They reported mixed human findings and called for controlled studies to separate ketone-specific effects from changes linked to diet, disease, circadian timing, and physiological stress.
