Tumor size serves as a prognostic indicator for curability

Smaller tumors in the lungs appear to be less likely to have spread than larger tumors among patients with asymptomatic lung cancer, suggesting that early screening may be useful in detecting cancers that are still curable, according to a new article in the Archives of Internal Medicine.

Protein associated with growth of tumors may prevent the spread of cancer

A protein associated with the growth of head and neck tumors may be a tumor suppressor that could prevent the spread of cancer when it is expressed above normal levels, according to a study published in the Journal of the National Cancer Institute (JNCI).

Simple diagnostic imaging procedure changes treatment for lower back pain

A simple diagnostic imaging procedure can help identify patients with lower back pain who would benefit from spinal injections and spare those who would not, according to a study appearing in the February issue of Radiology.

Common genetic variation increases SIDS risk in African Americans

About five percent of deaths from SIDS (sudden infant death syndrome) in African Americans can be traced to defects in one gene and half of those deaths result from a common genetic variation that increases an infant's risk of developing an abnormal heart rhythm during times of environmental stress

Chink in cancer's armor

Much as the famed starship Enterprise would deploy a deflector shield to evade enemy attack, tumor cells are capable of switching on a molecular force field of their own to fend off treatments aimed at killing them. Now University of Florida researchers have found a chink in their armor.

Changes in the tissue environment of the breast that occur after pregnancy promote the metastasis of breast tumor cells

Changes in the tissue environment of the breast that occur after pregnancy promote the metastasis of breast tumor cells. The paper by McDaniel et al., "Remodeling of the mammary microenvironment following lactation promotes breast tumor cell metastasis.

Aging cells help make old bodies

Brown University biologists have uncovered intriguing evidence to support the theory that old cells help make old bodies. In a study of baboons, scientists showed that as these animals age, the number of aging cells in their skin significantly increases.

New findings help researchers revise models of mammalian sense of smell

In a mouse model, University of Pennsylvania School of Medicine researchers discovered that olfactory sensory neurons expressing the same receptor responded to a specific odor with an array of speeds and sensitivities, a phenomenon previously not detected in the mammalian sense of smell.

New DNA-based cell adhesion strategy

A new technique in which single strands of synthetic DNA are used to firmly fasten biological cells to non-biological surfaces has been developed by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley.
