CHAPEL HILL, N.C. – The promise of vaccines targeted against various types of cancer has raised the hopes of patients and their families. The reality, however, is that these promising treatments are difficult to develop. One of the challenges is identifying a discrete cellular target to stop cancer growth without inactivating the immune system. Scientists at UNC Lineberger Comprehensive Cancer Center report a laboratory finding that has the potential to increase the effectiveness of therapeutic cancer vaccines.

PHILADELPHIA – It took 12 years and a creation of a highly sophisticated transgenic mouse, but researchers at Kimmel Cancer Center at Jefferson have finally proven a long suspected theory: Inflammation in the breast is key to the development and progression of breast cancer.

In the December 15 issue of Cancer Research, the scientists say they can now definitively show that an inflammatory process within the breast itself promotes growth of breast cancer stem cells responsible for tumor development.

People can be reassured that while alcohol may slow down digestion after a rich calorific meal, enjoyed by many during the Christmas season, it will not cause indigestion symptoms such as heartburn, belching and bloating, finds research in the Christmas issue published on bmj.com today.

The skeletons of kings and queens lying in mass graves in the Royal Basilica of Saint-Denis in Paris could finally have the solemn funeral ceremonies they deserve, say experts in the Christmas issue published on bmj.com today.

Many of the graves in the Royal Basilica were destroyed by revolutionaries in 1793 and very few remains of the mummified bodies have been preserved and identified.

Dr Philippe Charlier led the scientific breakthrough that has identified the head of the French King, Henri IV.

The imaging of tumour growth in zebrafish has revealed for the first time how newly formed cancer cells have the capacity to co-opt the immune system into spreading the disease, leading the way for investigations into potential therapies for eliminating early-stage cancer in humans. Using different coloured fluorescent tags, scientists at the University of Bristol labelled immune cells and tumour-forming cells in the translucent zebrafish in order to track their behaviour and interactions by live cell imaging.

Using automated screening techniques developed by pharmaceutical companies to find new drugs, researchers from UC San Diego and three other research institutions have discovered a molecule with the most potent effects ever seen on the biological clock. Dubbed "longdaysin," for its ability to dramatically slow down the biological clock, the new compound could pave the way for a host of new drugs to treat severe sleep disorders or quickly reset the biological clocks of jet-lagged travelers who regularly travel across multiple time zones.

Jeremy Keenan and colleagues report that during a cluster-randomized clinical trial in Ethiopia, nasopharyngeal pneumococcal resistance to macrolides was significantly higher in communities randomized to receive azithromycin compared with untreated control communities.

DALLAS – Dec. 14, 2010 – Researchers at UT Southwestern Medical Center have discovered sets of genes active in cancer cells and normal tissue that predict survival time and potential new treatments for patients with non-small cell lung cancer.

"Patient responses to cancer treatment vary widely and often depend on subtle biological differences among tumors," said Dr. David Mangelsdorf, chairman of pharmacology at UT Southwestern and co-lead author of the study, published Dec. 14 by PLoS Medicine.

TORONTO, Ont. 14, 2010—Simple changes to how ventilators are used could almost double the number of lungs available for transplants, according to new international research involving a doctor at St. Michael's Hospital.

INDIANAPOLIS -- The latest weapon against inoperable liver cancer is so tiny that it takes millions of them per treatment, but according to interventional radiologists at the Indiana University School of Medicine, those microscopic spheres really pack a therapeutic punch.

The glass spheres contain a radioactive element, yttrium-90, more commonly known as Y-90, which emits radiation for a very limited distance so that healthy tissue around the tumor remains unaffected. (2.5mm or less than 1/16th inch in soft tissue).

CHICAGO --- People will gain significantly less weight by middle age – especially women – if they engage in moderate to vigorous activity nearly every day of the week starting as young adults, according to new Northwestern Medicine research.

Use of certain measures for lung preservation after brain death in potential organ donors resulted in a nearly doubling of lungs eligible for donation, compared to a conventional strategy that is used, according to preliminary research published in the December 15 issue of JAMA.

Analysis has identified variations of a gene that are associated with a type of tumor that forms within the adrenal gland, according a study in the December 15 issue of JAMA. The age group in which these variations were found are frequently excluded from genetic screening models for this type of tumor.

Scientists at the University of California, San Diego School of Medicine have described for the first time a key inhibitory role for the IL-1 signaling pathway in the human innate immune system, providing novel insights into human inflammatory bowel disease (IBD) and potential new treatments.

The research, led by Jose M. Gonzalez-Navajas, PhD, and Eyal Raz, MD, a professor of medicine at UC San Diego, is published as a Brief Definitive Report in the December issue of The Journal of Experimental Medicine.
