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.

Over-expression of heme oxygenase-1 enzyme protects the heart from doxorubicin damage

Life-threatening heart damage is an adverse side effect of the cancer drug doxorubicin, damage that also limits the use of newer chemotherapeutic agents such as trastuzumab and imatinib. The ability to protect the heart from these side effects would benefit patients, including cancer survivors who are at risk of developing heart damage years later, and it also could allow safer use of these drugs at higher doses.

Determining Ectopeptidase Activity: An Interview with Professor Stephen Weber, University of Pittsburgh

The scope of the activity of neuropeptides is remarkably broad. For example, neuropeptides are involved in pain control, mood/depression/eating disorders, social and emotional behaviour, body weight, drug abuse, stress, reproduction, motor control, memory, and in maintaining neuronal health when they are stressed.

NIH-funded analysis identifies three genes that contribute to most common form of glaucoma

An analysis funded by the National Eye Institute (NEI), part of the National Institutes of Health, has identified three genes that contribute to the most common type of glaucoma. The study increases the total number of such genes to 15.

Researchers discover first broad spectrum drug that can potently kill aging cells in culture

Researchers from the University of Arkansas for Medical Sciences and other institutions are reporting the discovery of the first broad spectrum drug that can potently kill senescent (or aging) cells in culture and effectively clear the cells in animals by specifically targeting a pathway that is critical for the survival of senescent cells.

New study examines antioxidant effects of pomegranate extract on cardiovascular risk factors

A new study assessing the antioxidant effects of pomegranate extract on cardiovascular risk factors and muscle function showed reductions in blood pressure and some atheroprotective benefits, but no effects on inflammation, oxidative strength, or muscle strength.

Antioxidants may help prevent or preempt migraines

Migraines can be triggered by a variety of factors, including stress, sleep disruption, noise, odors, and diet. The findings of a new Headache review indicate that many of these factors converge on a common pathway involving oxidative stress.

Could statins treat muscular dystrophy? An interview with Dr. Nick Whitehead and Dr Stan Froehner

In addition to their well established cholesterol lowering benefits, statins also have potent anti-inflammatory, anti-fibrotic and antioxidant effects, which continue to be identified in a wide range of diseases.

Testosterone cause of sex differences in the occurrence of Parkinson’s disease, new research suggests

Men are twice as likely as women to develop Parkinson's disease, a nervous system disorder characterized by tremors and difficulty moving. New research to be presented at Cardiovascular, Renal and Metabolic Diseases: Physiology and Gender suggests that the difference in risk may be due to the presence of the male sex hormone testosterone.

Utah chemists devise new way to detect DNA damage

University of Utah chemists devised a new way to detect chemical damage to DNA that sometimes leads to genetic mutations responsible for many diseases, including various cancers and neurological disorders.

Findings support higher dietary requirements of vitamin E for obese people with metabolic syndrome

A recent study suggests that obese people with metabolic syndrome face an unexpected quandary when it comes to vitamin E - they need more than normal levels of the vitamin because their weight and other problems are causing increased oxidative stress, but those same problems actually cause their effective use of vitamin E to be reduced.

Jet lag-like sleep disruptions promote memory problems, chemical alterations in the brain

Chemical changes in brain cells caused by disturbances in the body's day-night cycle may be a key underlying cause of the learning and memory loss associated with Alzheimer's disease, according to a University of California, Irvine study.

UTMB researchers find mechanisms to determine when pregnant women go into labor

During the last few weeks of a woman's pregnancy, many keep an overnight bag ready to go at a moment's notice in case they begin to go into labor. They do this because there is no clear signal that labor is about to begin - before the body makes it abundantly clear that this process has started. Understanding the mechanisms that initiate this process is especially important when treating women at risk of going into labor early.

Study confirms neuroprotective effects of hypothermia in newborns with HIE

A unique study at Children's Hospital Los Angeles of newborns treated with hypothermia for hypoxic-ischemic encephalopathy (HIE) - a condition that occurs when the brain is deprived of an adequate oxygen supply - confirms its neuroprotective effects on the brain.
