Scientists Discover Clues To What Makes Human Muscle Age

A study led by researchers at the University of California, Berkeley, has identified critical biochemical pathways linked to the aging of human muscle. By manipulating these pathways, the researchers were able to turn back the clock on old human muscle, restoring its ability to repair and rebuild itself. The findings will be reported in the Sept. 30 issue of the journal EMBO Molecular Medicine, a peer-reviewed, scientific publicationof the European Molecular Biology Organization. "Our study shows that the ability of old human muscle to..."

Muscle Regeneration Via MacroPhage Action

For scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, what seemed like a disappointing result turned out to be an important discovery. Their findings, published online this week in the journal Proceedings of the National Academy of Sciences (PNAS), provide conclusive proof that, when a muscle is injured, white blood cells called macrophages play a crucial role in its regeneration. The scientists also uncovered the genetic switch that...

Can Your Home Trigger Asthma?
 Environmental Toxicologists Link Household Bacteria To...

Scientists have found that chemicals called endotoxins can inflame airways and trigger asthma. Endotoxins are shed by bacteria in household dust. Experts say better home hygiene, washing bed linens in hot water at least once a week, and using allergen-prevention pillow cases and mattress covers can reduce the risk of asthma attacks. Researchers say asthma and allergy triggers may be commonly found at home. That means there are things you can do to reduce the cause of your family's symptoms.

Trans Fats Hinder Multiple Steps In Blood Flow Regulation Pathways

Partially hydrogenated vegetable oils in processed foods contain trans fatty acids that interfere with the regulation of blood flow. A new report reveals a new way in which these “trans fats” gum up the cellular machinery that keeps blood moving through arteries and veins. In the August 2009 issue of the international journal Atherosclerosis, University ...

Reduced Lung Capacity Linked To Cardiovascular Disease By Inflammation

People who have a reduced lung capacity may have a greater risk of heart attack and stroke because they show evidence of inflammation, reveals a study published online ahead of print in Thorax. This association is not related to smoking, respiratory diseases or obesity. The New Zealand researchers took measurements of lung capacity and inflammation ...

From Fat To Chronic Inflammation

Researchers may have found a key ingredient in the recipe that leads from obesity to chronic low-grade inflammation, according to a report in the September issue of Cell Metabolism, a Cell Press publication. Chronic inflammation within fat tissue is now recognized as a contributor to the many ill health consequences that come with obesity, from diabetes ...

Both Major Theories About Human Cellular Aging Supported By New Research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells. These research findings, presented at the American Society for Cell Biology ...

Pitt Study Finds Molecular Link Between Insulin Resistance And Inflammation

An exploration of the molecular links between insulin resistance and inflammation may have revealed a novel target for diabetes treatment, say scientists at the John G. Rangos Sr. Research Center, Children’s Hospital of Pittsburgh of UPMC. Their findings were published earlier this month in the online version of Diabetes, one of the journals of the ...

Research Shows Low Vitamin D Levels Raise Risk of Heart Disease...

Low levels of vitamin D are known to nearly double the risk of cardiovascular disease in patients with diabetes, and researchers at Washington University School of Medicine in St. Louis now think they know why. They have found that diabetics deficient in vitamin D can’t process cholesterol normally, so it builds up in their blood vessels, ...

Fatigue Related To Radiotherapy May Be Caused By Inflammation

Patients who experience fatigue during radiotherapy for breast or prostate cancer may be reacting to activation of the pro-inflammatory cytokine network, a known inflammatory pathway, according to a report in Clinical Cancer Research, a journal of the American Association for Cancer Research. Julie Bower, Ph.D., an associate professor in the Department of Psychology and Psychiatry at ...

Scientists Uncork Potential Secret Of Red Wine’s Health Benefits

Scientists from Scotland and Singapore have unraveled a mystery that has perplexed scientists since red wine was first discovered to have health benefits: how does resveratrol control inflammation? New research published in the August 2009 print issue of The FASEB Journal, not only explains resveratrol’s one-two punch on inflammation, but also show how it—or a ...

Omega Fatty Acid Balance Can Alter Immunity And Gene Expression

For the past century, changes in the Western diet have altered the consumption of omega-6 fatty acids (w6, found in meat and vegetable oils)...
