Many children, especially those with eczema, are unnecessarily avoiding foods based on incomplete information about potential food-allergies, according to researchers at National Jewish Health. The food avoidance poses a nutritional risk for these children, and is often based primarily on data from blood tests known as serum immunoassays.

November 4, 2010 – (BRONX, NY) -- A team of scientists has found a way to eliminate a debilitating side effect associated with one of the main chemotherapy drugs used for treating colon cancer. The strategy used in their preclinical research—inhibiting an enzyme in bacteria of the digestive tract—could allow patients to receive higher and more effective doses of the drug, known as CPT-11 or Irinotecan.
PROVIDENCE, R.I. [Brown University] — In a major new study announced today by the National Cancer Institute, researchers including Brown University biostatistian Constantine Gatsonis and his colleagues found that screening for lung cancer using helical CT scanning reduced lung cancer deaths by 20 percent compared to using chest X-rays.
A debilitating side effect of a widely used but harshly potent treatment for colon cancer could be eliminated if a promising new laboratory discovery bears fruit.
The pre-clinical finding, published in the Nov. 5, 2010, issue of the journal Science, relates to the drug CPT-11, or Irinotecan, a chemotherapeutic agent used against colon cancer and other solid malignancies. It is believed to be the first successful targeting of an enzyme in symbiotic bacteria found in the digestive system.
Tiny variants in a protein that alerts the immune system to the presence of infection may underlie the rare ability of some individuals to control HIV infection without the need for medications.
Researchers at the University of Cambridge hope to revolutionise cancer therapy after discovering one of the reasons why many previous attempts to harness the immune system to treat cancerous tumours have failed.
Researchers at Washington University School of Medicine in St. Louis have identified a gene linked to the spread of eye melanoma.
Although more research is needed, the researchers say the discovery is an important step in understanding why some tumors spread (metastasize) and others don't. They believe the findings could lead to more effective treatments.

Menlo Park, Calif.—Calcium regulates many critical processes within the body, including muscle contraction, the heartbeat, and the release of hormones. But too much calcium can be a bad thing. In excess, it can lead to a host of diseases, such as severe muscle weakness, a fatal reaction to anesthesia or sudden cardiac death.
Nanoparticles could help smuggle drugs into the gut, according to a study published this month in the International Journal of Nanotechnology.
Quebec City, November 4, 2010—A team of Université Laval and Danisco researchers has just unlocked the secret of bacteria's immune system. The details of the discovery, which may eventually make it possible to prevent certain bacteria from developing resistance to antibiotics, are presented in today's issue of the scientific journal Nature.
Researchers have experimentally shown that some species of reef fish will enact punishment on the parasitic saber-tooth blennies that stealthily attack them from behind and take a bite, even though their behavior offers no immediate gain. The study, published online on November 4 in Current Biology, a Cell Press publication, shows that punishment ultimately serves all members of the reef fish species well.
The adult human skeleton undergoes constant remodeling, with new bone forming at sites that have been broken down by a precise process called resorption. During remodeling, skeletal stem cells are recruited to resorption sites and directed to differentiate into bone-forming cells. Osteoporosis, a condition characterized by weak and fragile bones, develops when there is an imbalance in the remodeling process and more bone is lost than replaced.
A new study published today shows a genetic 'battle of the sexes' could be much harder to resolve and even more important to evolution than previously thought.
