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 granted third patent for Protandim

LifeVantage Corporation, has been granted a third patent for its flagship product Protandim from the United States Patent and Trademark Office. Protandim has been clinically proven in earlier studies to slow the progressive rate of aging by reducing oxidative stress and this new patent further documents Protandim’s® effect on antioxidant enzymes in vivo, describing anti-inflammatory effects such as the lowering of C-reactive protein.

Research study to identify the appropriate amount of DHA required for promoting optimal heart health

A team of French scientists have found the dose of DHA (docosahexaenoic acid) that is "just right" for preventing cardiovascular disease in healthy men. In a research report appearing in the September 2009 print issue of The FASEB Journal, the scientists show that a 200 mg dose of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems, such as those related to aging, atherosclerosis, and diabetes. This study is the first to identify how much DHA is necessary to promote optimal heart health.

Low-carbohydrate and high-protein diet increases the risk for atherosclerosis and impaired blood vessels

Even as low-carbohydrate/high-protein diets have proven successful at helping individuals rapidly lose weight, little is known about the diets' long-term effects on vascular health.

UCLA highlights the benefits of restful sleep for increased efficiency

According to the journal Science, the function of sleep is one of the 125 greatest unsolved mysteries in science. Theories range from brain "maintenance" - including memory consolidation and pruning - to reversing damage from oxidative stress suffered while awake, to promoting longevity. None of these theories are well established, and many are mutually exclusive.

Researchers find link between chronic kidney disease and impaired mitochondrial respiratory system

Chronic kidney disease (CKD) has been linked to oxidative stress caused by dysregulation of the genes that control mitochondria. A study in the open access journal BMC Genomics has revealed alterations in respiration gene expression in the white blood cells of CKD patients.

Scientists find another mechanism that destroys tumor cells

Cells don't like to be alone. In the early stages of tumor formation, a cell might be pushed out of its normal home environment due to excessive growth. But a cell normally responds to this homeless state by dismantling its nucleus, packing up its DNA, and offering itself to be eaten by immune system cells. Simply put, the homeless cell kills itself. This process, known as apoptosis, typically stops potential cancer cells before they have a chance to proliferate.

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.

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.
