ANN ARBOR, Mich. — Black people with early stage liver cancer were more likely than white patients to die from their disease, according to a new study from the University of Michigan Comprehensive Cancer Center.

Five years after diagnosis, 18 percent of white liver cancer patients were alive but only 15 percent of Hispanic patients and 12 percent of black patients were. Median survival times ranged from 10 months for whites and Hispanics to 8 months for blacks.

MADISON — An over-the-counter herbal treatment believed to have medicinal benefits has minimal impact in relieving the common cold, according to research by the University of Wisconsin-Madison School of Medicine and Public Health.

Ocean acidification changes nitrogen cycling in world seas

Increasing acidity in the sea's waters may fundamentally change how nitrogen is cycled in them, say marine scientists who published their findings in this week's issue of the journal Proceedings of the National Academy of Sciences (PNAS).

More effective risk-adjusted chemotherapy and sophisticated patient monitoring helped push cure rates to nearly 88 percent for older adolescents enrolled in a St. Jude Children's Research Hospital acute lymphoblastic leukemia (ALL) treatment protocol and closed the survival gap between older and younger patients battling the most common childhood cancer.

It's long been accepted by biologists that environmental factors cause the diversity—or number—of species to increase before eventually leveling off. Some recent work, however, has suggested that species diversity continues instead of entering into a state of equilibrium. But new research on lizards in the Caribbean not only supports the original theory that finite space, limited food supplies, and competition for resources all work together to achieve equilibrium; it builds on the theory by extending it over a much longer timespan.

BOSTON – December 20, 2010 – In some adults, the white fat cells that we all stockpile so readily are supplemented by a very different form of fat—brown fat cells, which can offer the neat trick of burning energy rather than storing it. Researchers at Joslin Diabetes Center, which last year led the way in demonstrating an active role for brown fat in adults, now have identified progenitor cells in mouse white fat tissue and skeletal muscle that can be transformed into brown fat cells.

In notable back-to-back papers appearing in the prestigioous journal Science in October, teams of researchers, one led by Nora Besansky, a professor of biological sciences and a member of the Eck Institute for Global Health at the University of Notre Dame, provided evidence that Anopheles gambiae, which is one of the major mosquito carriers of the malaria parasite in Sub-Saharan Africa, is evolving into two separate species with different traits.

 researchers squeezing out maximum health benefits

The team published the best health-promoting combinations of those natural antioxidants in a recent issue of the Journal of Food Science. The paper's lead author, Brenner Freeman, was a BYU undergrad when he conducted the research.

Now applying to medical schools, Brenner chose to study oranges because he was raised on a citrus orchard in Arizona.

Fast-moving objects create blurry images in photography, and the same challenge exists when scientists observe cellular interactions within tissues constantly in motion, such as the breathing lung. In a recent UCSF-led study in mice, researchers developed a method to stabilize living lung tissue for imaging without disrupting the normal function of the organ. The method allowed the team to observe, for the first time, both the live interaction of living cells in the context of their environment and the unfolding of events in the immune response to lung injury.

UCSB scientists demonstrate biomagnification of nanomaterials in simple food chain

(Santa Barbara, Calif.) –– An interdisciplinary team of researchers at UC Santa Barbara has produced a groundbreaking study of how nanoparticles are able to biomagnify in a simple microbial food chain.

Using acid suppressive medications, such as proton pump inhibitors and histamine2 receptor antagonists, may increase the risk of developing pneumonia, states an article in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj092129.pdf.

György Horvath from the University of Gothenburg, Sweden, and researchers from the University of Gävle and KTH Royal Institute of Technology have been able to confirm in tests that ovarian cancer tissue and healthy tissue smell different. The results were published recently in the journal Future Oncology.
