Drug that restricts blood supply to prostate tumors delays disease progression

A blood vessel-blocking drug called tasquinimod slowed the rate of disease progression in a clinical trial of 200 prostate cancer patients, according to experts at Johns Hopkins, Roswell Park Cancer Institute and Duke University.

Tasquinimod is a so-called "anti-angiogenesis" drug that squeezes off blood supply to prostate tumors by blocking new blood vessel development. Tumors require these vast networks of blood vessels to supply nutrients.

VARI findings could help diagnose and treat liver cancer

Grand Rapids, Mich. (June 8, 2010) – In collaboration with the National Cancer Centre, Singapore, Van Andel Research Institute (VARI) researchers have identified an enzyme that could help diagnose and treat cholangiocarcinoma, a form of liver cancer that strikes up to 3,000 new patients each year in the United States.

New type of human stem cell may be more easy to manipulate

Researchers from the Massachusetts General Hospital Center for Regenerative Medicine (MGH-CRM) and the Harvard Stem Cell Institute have a developed a new type of human pluripotent stem cell that can be manipulated more readily than currently available stem cells. As described in the June 4 Cell Stem Cell, these new cells could be used to create better cellular models of disease processes and eventually may permit repair of disease-associated gene mutations.

Income, race combine to make perfect storm for kidney disease

African Americans with incomes below the poverty line have a significantly higher risk of chronic kidney disease (CKD) than higher-income African-Americans or whites of any socioeconomic status, research led by scientists at Johns Hopkins and the National Institute on Aging shows. Conducted in a racially and socioeconomically diverse sample of participants from the city of Baltimore, Md., the study could help researchers eventually develop strategies to prevent CKD in vulnerable populations.

Allowing body checking in youth hockey may increase risk of injury, including severe concussions

A comparison of hockey leagues in Canada for 11-12 year old players finds that compared with leagues that do not allow body checking, those that do have an associated 3-fold increased risk of game-related injuries, including severe injuries and severe concussions, according to a study in the June 9 issue of JAMA.

Bodychecking triples injury risk in Pee Wee hockey

Bodychecking in Pee Wee hockey (with players aged 11-12) more than triples the risk of concussion and injury, according to a new study by researchers at the University of Calgary.

The researchers compared rates of injury between Alberta Pee Wee leagues, which allow body checking, and Quebec Leagues, which don't. The study followed 74 Alberta teams (1,108 players) and 76 Quebec teams (1,046 players) for a season, recording how and when injuries occurred during a game.

Protein could heal erectile dysfunction after cancer surgery

CHICAGO --- After men have surgery to remove a cancerous prostate gland, up to 80 percent of them will lose the ability to have an erection because of damage to a critical nerve that runs along the prostate.

New research from Northwestern University Feinberg School of Medicine shows the damaged nerve can be regenerated more quickly with a protein called sonic hedgehog delivered via a nanofiber gel.

Success with 'cisgenics' in forestry offers new tools for biotechnology

CORVALLIS, Ore. – Forestry scientists at Oregon State University have demonstrated for the first time that the growth rate and other characteristics of trees can be changed through "cisgenics" – a type of genetic engineering that is conceptually similar to traditional plant breeding.

Cisgenics uses genes from closely related species that usually are sexually compatible. If governments choose to regulate it similarly to conventional breeding, experts say, it could herald a new future for biotechnology, not only in forestry but crop agriculture and other areas.

Fire may be key to reviving dogwood trees in Eastern forests

WEST LAFAYETTE, Ind. - Proper and timely burning of some Eastern U.S. forests could help revitalize flowering dogwood trees, which benefits a wide range of species, a Purdue University report shows.

Invasive tallowtree spreading rapidly across Gulf coast

KNOXVILLE, TN – A study by a USDA Forest Service Southern Research Station scientist shows the numbers of nonnative Chinese tallowtree in Louisiana, Mississippi and east Texas grew by about 370 percent over a 16-year period. The spread of the invasive plant may create problems for plants and wildlife along the Gulf coast.

Early consumption of soda indicator of unhealthy diet

Young girls who drink soda have less healthy diets through adolescence than their peers who do not drink soda, according to a Penn State study.

The ten-year study showed that girls who drank soda at age five had diets that were less likely to meet nutritional standards for the duration of the study, which ended at age 15. Girls who did not drink soda at age five did not meet certain nutritional requirements, but their diets were healthier.

Research shows personality can predict fertility

The reproductive success of both men and women is influenced by our personality traits, according to new research from the University of Sheffield.

The study, which was published yesterday (7 June 2010) in the Proceedings of the National Academy of Sciences, found that women with higher levels of neuroticism and more extravert men, are likely to give birth to a larger number of children in societies with traditionally high birth rates.

Poor health? Easier for some to blame bad genes than change lifestyle

Does knowing that genes are partly responsible for your health condition mean you are less likely to be motivated to find out about the benefits of behavioral changes? According to Dr. Suzanne O'Neill from the National Human Genome Research Institute/National Institutes of Health, and her colleagues, people on the whole are still interested in how health habits affect disease risk.
