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

Novel DNA nanoplatform offers hope for chronic gum disease

Millions of people worldwide live with periodontitis, a chronic gum disease that can progressively destroy the tissues and bone supporting the teeth despite conventional treatment.

Lactoferrin yogurt helps preserve iron stores in women with gestational diabetes

In a double-blind pilot trial, lactoferrin-enriched yogurt added to routine iron supplementation helped prevent ferritin decline in pregnant women with gestational diabetes and reduced iron stores. The intervention was well tolerated and produced modest changes in selected gut bacteria, but did not significantly improve anemia or metabolic outcomes.

Micro and nanoplastics in the blood linked to increased heart attack risk factors

People who have suffered a serious heart attack had higher levels of micro and nanoplastics in their blood, compared to patients diagnosed with chronic ischemic heart disease and those who have normal blood vessels supplying the heart, according to a study published in the European Heart Journal today (Wednesday).

Mitochondrial DNA mutations link to cardiometabolic parameters in metabolic syndrome

Mitochondrial DNA (mtDNA) variability, especially heteroplasmy, is believed to affect cellular immunobiogenesis, particularly in monocytes in metabolic syndrome (MetS).

Cell death crosstalk network drives acute respiratory distress syndrome

Acute respiratory distress syndrome (ARDS) remains one of the deadliest complications of severe infections, sepsis, trauma, and viral pneumonia, yet decades of research have produced few targeted therapies capable of improving patient outcomes.

Study reports a counterintuitive new approach to treating mesothelioma

Mesothelioma is a rare but aggressive cancer, usually caused by exposure to asbestos. Inhaled asbestos fibers become lodged in the lungs, causing inflammation that can lead to tumor formation decades later. Worldwide, about 30,000 people are diagnosed with mesothelioma each year.

Advanced synthetic grafting material fights bone cancer and prevents infection

Primary bone tumors, such as osteosarcoma, have seen stagnant survival rates over the past four decades. Surgical removal of the tumor is critical, but local recurrence may occur when tumours are close to vital structures, often resulting in amputation.

Long-term exposure to air pollution linked to increased risk of Parkinson’s disease

Air pollution is a major public health issue, with long-term exposure to fine particulate matter linked with an increased risk of various diseases, including stroke and dementia.

Cosmetic microneedles deliver actives where creams struggle

This review shows how microneedle-based cosmetic systems bypass the stratum corneum to deliver poorly penetrating actives, including peptides, retinoids, vitamins, niacinamide, hyaluronic acid, and hair-growth compounds, into viable skin layers.

Could IVF affect heart health after pregnancy?

Women with IVF-conceived pregnancies exhibit higher large artery stiffness, indicating potential cardiovascular risks that warrant further investigation.

Severe gum disease linked to early kidney function decline

A growing body of research suggests that the effects of periodontitis extend far beyond the mouth.

Smart prodrug targets Alzheimer's disease using hydrogen peroxide signals

A substance that worsens dementia has become a "switch" that initiates treatment. KAIST researchers have developed a new therapeutic approach that uses hydrogen peroxide (H₂O₂), a reactive oxygen species that damages cells and increases in the brains of patients with Alzheimer's disease, to activate a drug selectively in diseased brain tissue.

GLP-1 medications may improve long-term health for people with peripheral artery disease

GLP-1 receptor agonists (GLP-1 RA) medications were shown to reduce the number of deaths, amputations and hospitalizations among people with Type 2 diabetes who also had narrowed leg arteries associated with PAD (peripheral artery disease), according to new, independent research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

Experts reframe steatotic liver disease as a dynamic continuum

The classification of steatotic liver disease (SLD) is undergoing a major conceptual transformation. In a recent article published in eGastroenterology, Dr. Chen, Dr. Horn, and Prof. Tacke from Charité - Universitätsmedizin Berlin argue that metabolic dysfunction-associated steatotic liver disease (MASLD), metabolic dysfunction and alcohol-associated liver disease (MetALD), and alcohol-associated liver disease (ALD) should not be regarded as rigid diagnostic categories, but rather as interconnected and evolving disease trajectories.

Obesity drives distinct molecular pathway toward invasive breast cancer

A novel study has found that obesity is associated with a distinct molecular program driving the transition from early-stage, premalignant breast lesions to invasive breast cancer.

Review links iron-dependent cell death to pathogenesis of Friedreich's Ataxia

Published in the open-access journal Ferroptosis and Oxidative Stress, the review by Giovanni Cravin and Giorgio Cozza from the University of Padua examines the growing evidence linking ferroptosis to the pathogenesis of Friedreich's Ataxia (FRDA), a rare inherited neurodegenerative disease characterized by progressive neurological decline, cardiomyopathy, and premature mortality.

Blood metabolism maps how lifestyle tracks function in cognitive aging

A new study used pathway-level blood metabolomics to identify lifestyle-associated metabolic patterns linked to physical, cognitive, and daily functional performance across CN, MCI, and AD. The findings suggest that diet- and activity-linked pathway signals span energy, amino acid, lipid, inflammatory, oxidative stress, and microbiome-related metabolism, but require independent and longitudinal validation.
