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.

Unraveling molecular dysfunction due to environmental toxin exposure

In a new article published in the journal Molecular Neurodegeneration, researchers at the University of Missouri School of Medicine take some of the first steps toward unraveling the molecular dysfunction that occurs when proteins are exposed to environmental toxins. Their discovery helps further explain recent NIH findings that demonstrate the link between Parkinson's disease and two particular pesticides - rotenone and paraquat.

Strawberries improve antioxidant capacity of blood

A group of volunteers ate half a kilo of strawberries every day for two weeks to demonstrate that eating this fruit improves the antioxidant capacity of blood. The study, carried out by Italian and Spanish researchers, showed that strawberries boost red blood cells' response to oxidative stress, an imbalance that is associated with various diseases.

University of Texas professor recommends three postulates to find probable cause of AD

After more than 100 years following its pathologic description, the cause of Alzheimer's disease (AD) remains unknown. To test the validity of present and future proposals related to the probable cause of AD, three postulates, or necessary conditions, are recommended by Jack de la Torre, MD, PhD, Adjunct Professor of Psychology at the University of Texas, Austin, in an article published in the Journal of Alzheimer's Disease.

Scientists uncover new therapeutic target that could prevent stress-related cell death

Scientists from the Florida campus of The Scripps Research Institute have uncovered a potentially important new therapeutic target that could prevent stress-related cell death, a characteristic of neurodegenerative diseases such as Parkinson's, as well as heart attack and stroke.

Study: E-waste linked to adverse effects on human health

In addition to its damaging effect on the environment and its illegal smuggling into developing countries, researchers have now linked e-waste to adverse effects on human health, such as inflammation and oxidative stress - precursors to cardiovascular disease, DNA damage and possibly cancer.

Lactate shuttle also exists in human tumors

Researchers at the Kimmel Cancer Center at Jefferson have shed new light on the longstanding conundrum about what makes a tumor grow-and how to make it stop. Interestingly, cancer cells accelerate the aging of nearby connective tissue cells to cause inflammation, which ultimately provides "fuel" for the tumor to grow and even metastasize.

Omega-3 fatty acids reduce risk of heart attack in stent patients

Omega-3 fatty acids, combined with two blood-thinning drugs, significantly changed the blood-clotting process and may reduce the risk of heart attacks in patients with stents in their heart arteries, according to research reported in Arteriosclerosis, Thrombosis and Vascular Biology: Journal of the American Heart Association.

Baked, broiled fish consumption linked to reduced heart failure risk in postmenopausal women

The risk of developing heart failure was lower for postmenopausal women who frequently ate baked or broiled fish, but higher for those who ate more fried fish, in a study reported in Circulation: Heart Failure, an American Heart Association journal.

Bitter cumin contains high levels of antioxidants and protects against DNA damage

Bitter cumin is used extensively in traditional medicine to treat a range of diseases from vitiligo to hyperglycemia. It is considered to be antiparasitic and antimicrobial and science has backed up claims of its use to reduce fever or as a painkiller. New research published in BioMedCentral's open access journal BMC Complementary and Alternative Medicine shows that this humble spice also contains high levels of antioxidants.

Impaired ability to handle oxidative stress may contribute to asthma development

An impaired ability to handle oxidative stress that arises from exposure to secondhand smoke and other environmental triggers may contribute to the development of asthma, according to results obtained from the Shanghai Women's Health Asthma and Allergy Study. The results of the study suggest regulating the body's antioxidant defense system may play an important role in asthma prevention.

Insight into probiotic bacteria can help improve intestinal disease treatments

The gut may need bacteria to provide a little bit of oxidative stress to stay healthy, new research suggests. Probiotic bacteria promote healing of the intestinal lining in mice by inducing the production of reactive oxygen species, researchers at Emory University School of Medicine have shown.
