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.

Polydatin reduces ulcerative colitis by regulating intestinal immune cells

Ulcerative colitis (UC) is a chronic inflammatory bowel disease in which recurrent intestinal inflammation can be difficult to control over the long term.

Why keto appears to lower blood pressure for some people but not others

A narrative review finds that ketogenic diets may modestly lower blood pressure through weight loss, reduced visceral fat, improved insulin sensitivity, fluid and electrolyte shifts, and anti-inflammatory effects. However, effects vary across studies, long-term cardiovascular evidence remains limited, and diet quality, hydration, electrolyte balance, and medication monitoring are important.

New study challenges long-held view of common bacterial resident of the lungs

Our bodies are teeming with more than 35 trillion bacteria, coexisting in microbiomes inside our guts, mouths, lungs, skin and urogenital tract.

Mitochondrial rewiring may explain why orthoflaviviruses harm humans but persist in mosquitoes

Orthoflaviviruses reshape mitochondrial structure, metabolism, redox signaling, and quality control differently across human and mosquito models, helping explain their contrasting infection outcomes. The review highlights mitochondrial pathways that may support acute cellular damage in vertebrates but persistent, non-lethal infection in mosquitoes, pointing to potential antiviral targets.

Ultra-processed foods linked to higher prostate cancer risk in men

Ultra-processed foods (UPFs) account for nearly 60% of adults' and 70% of children's energy intake in the United States.

Laboratory chemical exposure and poor diet increase odds of health symptoms in young scientists

Young scientists who frequently handle laboratory chemicals and consume relatively few antioxidant-rich foods may be more likely to report symptoms such as fatigue, headaches, pallor, and easy bruising, according to a new study of university students in Nigeria.

Scientists identify parasite-specific protein linked to chronic Toxoplasma infections

Toxoplasma gondii, or Toxoplasma, is a parasite that infects hundreds of millions of people around the world.

Newly discovered protein pathway limits spinal cord injury damage

Spinal cord injury begins with immediate mechanical damage, but much of the lasting neurological loss develops during the secondary phase, when inflammation, oxidative stress and disrupted metabolism continue to injure surviving tissue.

Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

New review explores purinergic signaling pathways in osteoarthritis progression

A growing understanding of purinergic signaling is reshaping how scientists view osteoarthritis (OA), revealing an intricate communication network that influences joint inflammation, cartilage degeneration, bone remodeling, and chronic pain.

Fine particle pollution raises rheumatoid arthritis flare risk and disease activity

Higher ambient PM2.5 exposure was associated with increased rheumatoid arthritis disease activity and a greater likelihood of flares in a four-year South Korean cohort of 1,070 patients. The association appeared stronger with sustained exposure over approximately two weeks or longer, while women and nonsmokers showed more pronounced links between PM2.5 and DAS28-CRP.

Air pollution in pregnancy raises birth risks differently across trimesters

A population-based study of 26,582 live singleton births in Madrid found that associations between NO₂ exposure and adverse birth outcomes varied by pregnancy stage, with key patterns emerging in the first and third trimesters.

New review links obesity with accelerated biological aging mechanisms

The global rise in obesity and population aging represents a major public health challenge, with growing evidence suggesting that excess body fat not only increases the risk of chronic disease but may also accelerate the biological aging process.
