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.

New research could make it easier to grow health-promoting blood oranges

For the red pigmentation to develop, blood oranges normally require a period of cold as they ripen. The only place to reliably grow them on a commercial scale is in the Sicilian area of Italy around Mount Etna. Here, the combination of sun and cold/sunny days and warm nights provides ideal growing conditions.

FTY720 improves locomotor recovery in mice with SCI

A new study suggests that administering FTY720, an oral drug that has shown promise in trials for human multiple sclerosis, significantly improves locomotor recovery in mice with spinal cord injury.

Human diseases with Drosophila counterparts discussed at annual conference

More than two-thirds of human genes have counterparts in the well-studied fruit fly, Drosophila melanogaster, so although it may seem that humans don't have much in common with flies, the correspondence of our genetic instructions is astonishing. In fact, there are hundreds of inherited diseases in humans that have Drosophila counterparts.

Conference highlights studies on metabolism, aging and monarch butterfly migration

The Genetics Society of America's 53rd Annual Drosophila Research Conference, March 7-11 at the Sheraton Chicago Hotel & Towers, will showcase diverse efforts to understand basic biological processes through the easy-to-study fruit fly, Drosophila melanogaster, and other insects.

New clinical trial: Pycnogenol improves signs and symptoms of menopause

Half the population experiences menopause, and for those women, it is a condition they will experience for approximately one third of their lifetime. Alternative or natural remedies are an easy, effective way to improve signs and symptoms linked to the menopausal transition, without side effects.

Walnuts associated with better memory scores and cognitive function

Do you recall what you ate for breakfast today or dinner last night? According to new research, you may have a better chance of remembering if you include walnuts. Recent findings published in the Journal of Alzheimer's Disease report walnut consumption in a Mediterranean diet is associated with better memory scores and cognitive function.

Telomerase reactivation in malignant cells after genomic instability causes cancer progression

Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.

Tetrahydrobiopterin plays a key role in arterial health of women

Researchers studying why arteries stiffen in postmenopausal women have found a specific chemical cofactor that dramatically improves vascular function.

Parkinson’s disease gene - parkin explored: Study

Researchers at the University at Buffalo have discovered how mutations in the parkin gene cause Parkinson's disease, which afflicts at least 500,000 Americans and for which there is no cure. The results are published in the current issue of Nature Communications.

Researchers discover how mutations in parkin gene cause PD

Parkinson's disease researchers at the University at Buffalo have discovered how mutations in the parkin gene cause the disease, which afflicts at least 500,000 Americans and for which there is no cure.

Multiple DNA repair defect in monocytes

Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood - so-called monocytes - are extremely sensitive to reactive oxygen species (ROS).

Oxidative stress in sperm linked to male infertility

Universitat Autònoma de Barcelona (UAB) patented an innovative system to specify in a simple, cost-effective and reliable manner the infertility of a person through the study of oxidative stress on sperm, a parameter rarely studied until now.

Lycopene can kill prostate cancer cells

A nutrient in cooked tomatoes has been shown in laboratory studies to slow the growth of or even kill prostate cancer cells.

Study finds protein's entwined arm movements may control fate of potentially toxic payload

Like a magician employing sleight of hand, the protein mitoNEET -- a mysterious but important player in diabetes, cancer and aging -- draws the eye with a flurry of movement in one location while the subtle, more crucial action takes place somewhere else.

Cocoa can help prevent onset of colon carcinogenesis

A new study on living animals has shown for the first time that eating cocoa (the raw material in chocolate) can help to prevent intestinal complaints linked to oxidative stress, including colon carcinogenesis onset caused by chemical substances.

Neuronal energy deficit may cause Parkinson's disease

Scientists at the University of York have made a significant step forward in isolating the cause of Parkinson's disease in younger adults.

Grapes offer dramatic protection against age-related macular degeneration

Can eating grapes slow or help prevent the onset of age-related macular degeneration (AMD), a debilitating condition affecting millions of elderly people worldwide? Results from a new study published in Free Radical Biology and Medicine suggest this might be the case. The antioxidant actions of grapes are believed to be responsible for these protective effects.

Losartan may help prevent smoking-related COPD

Working with mice, scientists at Johns Hopkins have successfully used a commonly prescribed blood pressure medicine, losartan (Cozaar), to prevent almost all of the lung damage caused from two months of exposure to cigarette smoke. The treatment specifically targeted lung tissue breakdown, airway wall thickening, inflammation and lung over-expansion.

Four or more coffees reduce risk of womb cancer

According to a new study drinking four or more cups of coffee a day may reduce risk of developing endometrial cancer or womb cancer by almost 25 per cent.

Researchers decode and characterize DNA repair mechanism

Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes. It occurs when the body is exposed to excessive amounts of electrically charged, aggressive oxygen compounds. These are normally produced during breathing and other metabolic processes, but also in the case of ongoing stress, exposure to UV light or X-rays. If the oxidative stress is too high, it overwhelms the body's natural defences. The aggressive oxygen compounds destroy genetic material, resulting in what are referred to as harmful 8-oxo-guanine base mutations in the DNA.
