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

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.

Study highlights potential heart dangers from e-cigarette chemicals

Is vaping bad for my health? As people who use e-cigarettes and their loved ones pose questions like this, growing scientific evidence shows that the answer is yes.

Smart nanoplatform uses wound acidity to trigger accelerated healing

Infected wounds pose a significant medical challenge, often leading to delayed healing and complications due to bacterial biofilms and excessive inflammation.

Scientists find a universal gut microbiome pattern linked to colorectal cancer

Researchers analyzed 6,779 stool microbiome profiles and 906 tissue samples to identify a colorectal cancer microbial signature that remained consistent across age groups, populations, and sequencing methods. The signature aligned with tumor-resident microbes, showed weaker detection for adenomas, and was inversely associated with dietary fiber intake.

Study identifies fPRDM16 as target for age-related pulmonary fibrosis

A study published recently in Current Molecular Pharmacology has uncovered a key mechanism linking aging to persistent pulmonary fibrosis, identifying the transcriptional regulator fPRDM16 as a potential therapeutic target.

Blueberries may boost children's memory and mood

Research suggests blueberry compounds could enhance mood and cognitive function in children, yet stronger evidence is required for clinical recommendations.

Gene linked to lower BMI points researchers toward a new obesity target

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.

Scientists identify genes linking air pollution to severe asthma

For many people with asthma, air-quality advisories are harbingers of worsening symptoms. But for reasons science has struggled to explain, the extent to which pollution exacerbates asthma varies widely from person to person.

Melatonin improves skin flap survival by reducing ferroptosis

Random-pattern skin flaps are widely used to repair defects caused by trauma, burns, tumor removal, and other injuries because they can be designed without depending on a single named blood vessel.

Key Alzheimer's protein actively protects neurons from nuclear damage

Researchers at Niigata University's Brain Research Institute have uncovered a new function of amyloid precursor protein (APP), a molecule long studied as the precursor to amyloid-β (Aβ) in Alzheimer's disease (AD).

New study uncovers how prostate cancer cells evade treatment

Cancer cells are remarkably good at adapting to stress. When treatments damage them, they often find new ways to survive, fueling drug resistance and disease progression.

Lysosomal protein stabilizes mitochondria to prevent severe heart failure

A new study published in Engineering has uncovered a regulatory mechanism linking lysosomal function to mitochondrial stability in pathological cardiac hypertrophy, identifying transient receptor potential mucolipin 1 (TRPML1) as a key protective factor against the progression to heart failure.

Gut bacteria may help explain why fatigue appears before illness

A small study of healthy Japanese adults found that fatigue was associated with distinct gut microbiome, microbial gene, and fecal metabolite patterns. The findings suggest fatigue may track with altered microbial energy metabolism and oxidative stress-related functional potential, but larger longitudinal studies are needed to test causality and clinical value.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.
