Chemicals in cruciferous vegetables, such as broccoli, watercress, cabbage and cauliflower, appear to stop human prostate cancer cells from growing in mice by affecting the expression of proteins, says a University of Pittsburgh Cancer Institute study, abstract number 5601, being presented today at the annual meeting of the American Association for Cancer Research, at the Washington Convention Center in Washington, D.C.

Clinical trials not yet on horizon
An antibiotic commonly used to treat a variety of serious infections may also help prevent dementia in HIV patients, according to a test-tube study of human brain cells by Johns Hopkins University School of Medicine neurologist Jeffrey Rumbaugh, M.D., Ph.D.
Results of the lab study with ceftriaxone are expected to be presented at the American Academy of Neurology’s 58th annual meeting on April 5 in San Diego, Calif.

Female harbor seal pups whose blubber falls below average levels may be at higher risk of delayed sexual maturation or death, even if they get enough fat in their diets later on, according to a new study sponsored by The American Physiological Society and presented at Experimental Biology 2006.
The study found that harbor seals pups that were heavier when captured from the wild continued to gain weight and grow regardless of whether the researchers placed them on a high fat or
Preliminary study demonstrates calorie restriction reduces markers of aging
Can eating a low-calorie yet nutritionally balanced diet extend human life? Preliminary research suggests it might, so researchers at Washington University School of Medicine in St. Louis are launching a long-term study to find out.
In an editorial in the April 5 issue of the Journal of the American Medical Association, Luigi Fontana, M.D., Ph.D., assistant professor of medicine at Washington Unive
Small birth size has been shown to have adverse effects on the offspring in later life, including increased risks of heart disease, stroke, hypertension, type 2 diabetes, and other conditions. Now work presented at the European Congress of Endocrinology in Glasgow shows that women with a high testosterone level in pregnancy will produce smaller babies.
A group led by Dr Sven M. Carlsen at the University of Trondheim measured levels of four endogenous hormones at 17 and 33 weeks in 147 pr
Industry board issues ratings without playing games
According to a study led by Associate Professor Kimberly Thompson of the Kids Risk Project at Harvard School of Public Health (HSPH), 81% of a random sample of Mature-rated video games included content that was not noted on the game box. This is the first independent, quantitative study to characterize content in M-rated games related to violence, blood, sexual themes, substances, profanity, and gambling observed in game play.
A study led by researchers from the Howard Hughes Medical Institute has found that dasatinib provides significant benefit in chronic myeloid leukemia (CML) patients resistant to Gleevec® (imatinib), according to a study presented today during the 97th Annual Meeting of the American Association for Cancer Research.
In an update of a phase I study initiated in November 2003, researchers looked at the use of dasatinib in imatinib resistant or intolerant patients with CML in late chr
Results from a Phase III study of a new drug show promise for patients with colorectal cancer that has spread to other parts of the body, according to a study presented today during the 97th Annual Meeting of the American Association for Cancer Research.
Investigators have shown that panitumumab improves progression-free survival in patients with metastatic colorectal cancer (mCRC) who had failed standard chemotherapy. In the randomized trial of 463 patients, those who receive
Soymilk proves a popular option for lactose intolerant students
Offering soymilk to elementary school students boosts the number of children who select a calcium-rich beverage in the lunch line and reduces the amount of saturated fat consumed from calcium-rich beverages, according to a study in April’s Journal of the American Dietetic Association.
Almost a quarter of students were choosing soymilk over cow’s milk by the end of the four-week study, which was
Results from a new, five-year study show that regular use of popular prescription pain relievers may reduce the risk of breast cancer by up to 71 percent and may offer similar benefit in the prevention of prostate, colon and lung cancers.
The study findings were released today at the annual meeting of the American Association for Cancer Research in Washington, D.C.

Peace at any price? More than one parent has forked over cash in a desperate bid to stop their kids’ badgering for the hottest toy or the latest snack. Now researchers at Lucile Packard Children’s Hospital and Stanford’s School of Medicine have found that the more time California third-graders spent in front of the tube or playing video games, the more often they asked an adult to buy them items they saw on the screen.

Is greenness in your genes? A new study by University of Leicester psychologists aims to find out.
It will also reveal if people really are friendlier up north- environmentally friendlier that is. And it could reveal which is the ’greener sex’.
The National Environment & Personality Survey has been launched today (3 APRIL) by a team in the University of Leicester’s School of Psychology.
The study will examine regional and social differences in en
Whether a tiny yellow pigment is the main thing standing between many older people and macular degeneration is under study at the Medical College of Georgia.
Researchers are measuring this macular pigment that sits on the retina at the fovea, the point of highest vision acuity and best color vision, to better understand what a healthy, normal pigment looks like, says Dr. John Nolan, vision scientist and Fulbright postdoctoral fellow in the MCG Department of Ophthalmology.
Eighty-three per cent of college girls surveyed diet to lose weight, regardless of their current body weight. A study published today in the open access journal Nutrition Journal (http://www.nutritionj.com/) also reveals that college girls practice unhealthy behaviours, such as smoking or skipping breakfast, to lose weight. By contrast, only 19% of them exercise enough to promote weight loss. The authors of the study conclude that all college girls, regardless of whether they are normal weight
Multi-site vaccinations could protect against all four dengue viruses
An innovative new study explains, for the first time, the failure of previous attempts to vaccinate against the four known Dengue viruses, and it suggests a very simple solution – injecting the four vaccines simultaneously at different locations on the body.
A mosquito-born disease, Dengue kills tens of thousands of people per year and sickens 100 million more. Known as “bone-break disease,” Dengue is ch
The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver’s response to injury leads to liver cancer, researchers from Duke University Medical Center and John Hopkins University School of Medicine have found.
Because the pathway, called Hedgehog, is present only in immature, stem-like liver cells, the discovery offers hope for targeted treatment of liver cancer, one of the leading causes of cancer-related death in the world. Laborat
