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.

LifeVantage Corporation invites independent distributor applications in Mexico ahead of planned product launches

LifeVantage Corporation (OTCBB: LFVN), a science-based, natural products company dedicated to helping people reach their health and wellness goals through science-based solutions for oxidative stress and the maker of Protandim® and TrueScience™ Anti-Aging Cream, announced today that independent distributor applications and orders are being accepted in Mexico in anticipation of a launch late this summer.

Researchers find connection between eye disease and arginase

Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Georgia researchers say therapies to normalize its levels could halt progression of potentially blinding diseases such as diabetic retinopathy.

Discovery of mechanism that allows hepatitis C virus to remain in the body for decades

A study published in the Proceedings of the National Academy of Sciences (PNAS) shows that the virus blocks the actions of a specific ion channel in the cell membrane that would usually trigger apoptosis - the cell's self-destruct programme - and in doing so, has evolved another way of protecting itself from being eliminated from the body.

New findings on how hepatitis C survives for so long in the body

Researchers at the University of Leeds have discovered a previously unknown mechanism that allows the hepatitis C virus (HCV) to remain in the body for decades.

Protein DNA repair complex key to avoiding DNA repair mistakes

As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows.

Discovery of brain-protecting protein

Johns Hopkins researchers have discovered a novel protein that can protect brain cells by interrupting a naturally occurring "stress cascade" resulting in cell death.

One secret to how tuberculosis resists the host immune system

Mycobacterium tuberculosis is arguably the world's most successful infectious agent because it knows how to avoid elimination by slowing its own growth to a crawl. Now, a report in the July 10 issue of the journal Cell, a Cell Press publication, offers new insight into the bugs' talent for meager living.

Single gene found to control growth of some cancers

Research led by Ashok Aiyar, PhD, Associate Professor of Microbiology at LSU Health Sciences Center New Orleans, showing that a single gene can control growth in cancers related to the Epstein-Barr virus and that existing therapeutics can inactivate it, will be published in the June 12, 2009 online issue of PLoS Pathogens.

Oxidative stress strongly evident in the in-utero environment of the fetus with Down syndrome

A paper published in the Proceedings of the National Academy of Sciences by Tufts Medical Center and Tufts University researchers reports that amniotic fluid surrounding Down syndrome fetuses shows oxidative stress, a condition that could harm fetal cells and play a role in affected individuals. The results demonstrate secondary adverse consequences of Down syndrome and suggest potential prenatal therapies.

Low antioxidant intake is associated with low reproductive capacity in semen

Low antioxidant intake is associated with low reproductive capacity in semen. This is the finding of a new study carried out in two infertility centres in Alicante and Murcia, and which has been published online in the journal Fertility and Sterility.

Carbon monoxide reverses gastroparesis in mice

Mayo Clinic researchers have shown that very low doses of inhaled carbon monoxide in diabetic mice reverses the condition known as gastroparesis or delayed stomach emptying, a common and painful complication for many diabetic patients. The findings will be presented on June 1 at Digestive Disease Week in Chicago.

Adult bone marrow stem cells injected into skeletal muscle can repair heart tissue

University at Buffalo researchers have demonstrated for the first time that injecting adult bone marrow stem cells into skeletal muscle can repair cardiac tissue, reversing heart failure.

Oxidation of potassium channel in cells linked to loss of neuronal function in aging

Researchers at UMDNJ-Robert Wood Johnson Medical School are one step closer to determining how human cells can be protected against the affects of age-related neurodegeneration including Alzheimer's and Parkinson's disease.

Building a bridge from Alzheimer's disease to diabetes and vice versa

Modern societies face the increasing burden of age-related diseases, in particular Alzheimer's disease (AD) and type 2 diabetes (T2D).

Closer to an effective treatment for gum disease in smokers

Scientists in the USA have discovered why smokers may be more prone to chronic gum disease (periodontitis). One of the bacteria responsible for this infection responds to cigarette smoke - changing its properties and the way it infects a smokers mouth.

Discovery of major new treatment target in diseased arteries

Removing a single protein prevents early damage in blood vessels from triggering a later-stage, frequently lethal complication of atherosclerosis, according to research published online today in the journal Nature Medicine. By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers were able to provide complete protection against abdominal aortic aneurysm (AAA).

Grapes may prevent heart health risks beyond the simple blood pressure-lowering impact

Can a grape-enriched diet prevent the downhill sequence of heart failure after years of high blood pressure?

Regular exercise can prevent damage that causes leakage in the blood-brain barrier

Regular exercise can prevent the disruption of the blood brain barrier that normally occurs with a dose of methamphetamine comparable to that used by heavy meth users.

The effect of tea polyphenols on paracetamol-induced hepatotoxicity

Paracetamol is one of the most widely used, studied, and arguably the most notorious hepatotoxic drugs, which is safe at therapeutic doses but causes liver failure when overdosed.

Study looks at exposure to vibration in workplace

Speaking on April 19 at the Experimental Biology 2009 meeting in New Orleans, Dr. Kristine Krajnak, a team leader in the Engineering and Control Technologies Branch of the Health Effects Laboratory Division of NIOSH in Morgantown, West Virginia, describes results from the first study to directly link the different physical responses of tissue that occur with exposure to different vibration frequencies with biological mechanisms underlying the development of vascular dysfunction.
