Treating breast cancer with MammoSite® resulted in a low risk of complications and was generally well tolerated, according to a University of Pittsburgh School of Medicine study presented today at the 47th annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.
MammoSite, a type of breast brachytherapy (bray-kee-therapy), uses a single catheter inserted into the breast following lumpectomy, or surgical removal of a tumor, to deliver a high dose of radiation. Once the catheter is inserted, a tiny balloon is inflated and loaded with radioactive seeds that deliver prescribed levels of radiation to targeted tissue surrounding the tumor site.
"MammoSite is a type of partial breast irradiation that delivers radiation from the inside of the breast directly to the tumor site where cancer cells are most likely to reside," said Sushil Beriwal, M.D., assistant professor at the University of Pittsburgh School of Medicine and medical director of radiation oncology at Magee-Womens Hospital of the University of Pittsburgh Medical Center (UPMC). "Ours is one of the largest single-institution studies to confirm that it does this safely and with an acceptable level of toxicity."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
