Researchers at UT Southwestern Medical Center at Dallas have shown that some long-term breast-cancer survivors may have innate mechanisms to keep breast cancer at bay.
Their findings, published in the December issue of Clinical Cancer Research and available online, show that one-third of the longtime disease-free patients in the study had circulating tumor cells (CTCs). The presence of CTCs is often associated with a higher risk of recurrence if they are found soon after a mastectomy. The UT Southwestern discovery that CTCs can be found in patients up to 20 years after mastectomy is notable because these patients have a very low risk of recurrence. After 20 years, the risk of recurrence rises to 20 percent of survivors, and scientists are still unsure why.
"Dormancy is a mysterious phenomenon that occurs in certain types of cancer," said Dr. Jonathan Uhr, lead author of the study and professor in the Cancer Immunobiology Center and of microbiology and internal medicine. "The term refers to a recurrence of cancer long after the tumor has been removed."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
