Hydrogen sulfide protects blood vessels from diabetes complications

Hydrogen sulfide is a foul-smelling gas with an odor resembling that of rotten eggs. Sometimes called "swamp gas," this toxic substance is generally associated with decaying vegetation, sewers and noxious industrial emissions. And - as odd as it may seem - it also plays a critical role in protecting blood vessels from the complications of diabetes, according to a new study from the University of Texas Medical Branch at Galveston.

Antioxidants may help treat infertility problems in both women and men

A growing body of evidence suggests that antioxidants may have significant value in addressing infertility issues in both women and men, including erectile dysfunction, and researchers say that large, specific clinical studies are merited to determine how much they could help.

Mitochondrial genome undergoes random reorganisation during reprogramming

Induced pluripotent stem cells (iPS cells) are truly talented multi-taskers. They can reproduce almost all cell types and thus offer great hope in the fight against diseases like Alzheimer's and Parkinson's. However, it would appear that their use is not entirely without risk: during the reprogramming of body cells into iPS cells, disease-causing mutations can creep into the genetic material.

Blueberries can help prevent cell damage linked to cancer

Blueberries are among the nutrient-rich foods being studied by UAB Comprehensive Cancer Center investigators exploring the link between disease and nutrition. Dieticians there say as little as a cup a day can help prevent cell damage linked to cancer.

Early detection critical in preventing vision loss among Baby Boomers

Probably the most worrisome health concern for Baby Boomers as they age is the increased possibility of visual impairment or vision loss. For this reason, early detection is critical in successfully preventing and treating eye conditions such as macular degeneration, cataracts, glaucoma and diabetic retinopathy, before they lead to major visual changes.

Resveratrol may make old age more tolerable, but not prevent it

A University of Florida review of research finds the polyphenol compound known as resveratrol found in red wine, grapes and other fruits may not prevent old age, but it might make it more tolerable.

Strawberries improve antioxidant capacity of blood

A group of volunteers ate half a kilo of strawberries every day for two weeks to demonstrate that eating this fruit improves the antioxidant capacity of blood. The study, carried out by Italian and Spanish researchers, showed that strawberries boost red blood cells' response to oxidative stress, an imbalance that is associated with various diseases.

Healthy diet, antioxidants, critical nutrients and activities may provide the foundation to youthful living

As the baby boomer generation continues to increase in age, so does its passion to remain youthful, both inside and out. Beating the clock is now a multi-faceted, science-driven industry. From its age-old quests to find the elixir of life, to modern exploration of how microcellular activity contributes to metabolic breakdown, scientific research continues to advance its goals to enhance bodily energy, vigour and performance, and fade or stall the visible signs of aging.

Tips for building strong and healthy bones

Most of us think of our bone structure as a solid, static mass that is hard and unchanging. The fact is our skeletal structure is replaced approximately every ten years.

Inorganic nitrate reduces rate of heart dysfunction caused by doxorubicin

Virginia Commonwealth University researchers have found that nutrient supplementation, like the kind that is found in leafy greens, spinach and lettuce, may reduce the damage to the heart caused by a powerful anti-cancer drug.

Bitter cumin contains high levels of antioxidants and protects against DNA damage

Bitter cumin is used extensively in traditional medicine to treat a range of diseases from vitiligo to hyperglycemia. It is considered to be antiparasitic and antimicrobial and science has backed up claims of its use to reduce fever or as a painkiller. New research published in BioMedCentral's open access journal BMC Complementary and Alternative Medicine shows that this humble spice also contains high levels of antioxidants.

Mosquito's midgut bacteria can inhibit malaria parasite development

Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans.

Blueberries can protect against heart disease and cancer

The first analysis of the healthful antioxidant content of blueberries that grow wild in Mexico, Central and South America concludes that some of these fruits have even more healthful antioxidants than the blueberries - already renowned as "super fruits" - sold throughout the United States.

Blueberries may help fight obesity

Recently a study out of the Texas Women's University looked at whether blueberries with their high polyphenol content could help in fighting obesity. Blueberries after all have already been cited as having positive health effects on other conditions like cardiovascular disease and metabolic syndrome. The study was conducted in Petri dishes (not live animals) using a blueberry polyphenol extract and tissue cultures from mice.

New book on aging

Aging is a natural part of life. From the minute we are born we are heading in one certain direction: towards death. That said, it is possible to arrive at that ultimate destination graceful and vital to our last days rather than chronically ill suffering from one or many debilitating illnesses.

Breakdown products of thalidomide cause birth defects: New study

Thalidomide may have been withdrawn in the early 1960s for use by pregnant women, but its dramatic effects remain memorable half a century later. Now, researchers have taken a major step toward understanding exactly how thalidomide causes the birth defects.
