Next-generation microcapsules deliver 'chemicals on demand' <http://www.eurekalert.org/pub_releases/2009-10/acs-nmd102809.php>
Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. The new microcapsules burst when exposed to light, releasing their contents in ways that could have wide-ranging commercial uses from home and personal care to medicine.Their study appears in the Journal of the American Chemical Society, a weekly publication.

Concurrent imaging of metabolic and electric signals in the heart <http://www.eurekalert.org/pub_releases/2009-10/sfeb-ci102309.php>
Cardiac rhythm disorders can result from disturbances in cardiac metabolism. These metabolic changes are tightly linked with specific cardiac electrophysiology abnormalities -- such as depressed excitability, impaired intra- and extracellular conductivities, wave propagation block and alteration of conduction velocity -- action potential amplitude, and duration. The altered electrophysiology eventually can lead to arrhythmias, fibrillation and cardiac death; therefore, understanding the spatiotemporal complexity of the relationship between metabolism and electrophysiology is the challenge in developing new approaches for treatment of cardiac diseases.

Nanowire biocompatibility in the brain: So far so good <http://www.eurekalert.org/pub_releases/2009-10/src-nbi102209.php>
Scientists at Lund University have investigated this "worst case" by injecting nanowires in rat brains. The nanowires resemble in size and shape the registration nodes of electrodes of the future. The results show that the brain "clean-up cells," take care of the wires. After 12 weeks only minor differences were observed between the brains of the test group and the control group. The findings are published in Nano Letters.

Sensor biochips could aid in cancer diagnosis and treatment <http://www.eurekalert.org/pub_releases/2009-10/tum-sbc102109.php>
Researchers at TUM, the Technische Universitaet Muenchen, have developed a new test process -- using lab-on-a-chip technology -- for establishing whether or not a cancer patient's tumor cells will respond to a particular drug. Such sensor biochips could potentially be used in the future to aid in rapid identification of the most effective medication for individual patients.

Liver Removed And Re-Implanted For Cancer Treatment <http://www.medicalnewstoday.com/articles/169010.php>
Distinguished transplant and cancer <http://www.medicalnewstoday.com/info/cancer-oncology/whatiscancer.php> surgeon, Alan Hemming, MD, has been recruited to the University of California, School of Medicine to launch a multidisciplinary center for the treatment of advanced liver disease at the UC San Diego Medical Center and Moores UCSD Cancer Center. This innovative program is designed to offer adult and pediatric patients in the western United States a single destination for the treatment of complex liver disease, from advanced diagnostics to experimental medical therapies and novel approaches for liver resection and transplantation. "Whether you are suffering from liver failure, or primary or secondary liver malignancy, there are new combinations of treatment that can be delivered to you at UCSD Medical Center," said Hemming, professor of surgery and Chief of Transplantation and Hepatobiliary Surgery. "If you have been told that you have untreatable liver disease, there is hope for you here. As a world-recognized academic medical center, UC San Diego has the expertise, resources and skill to take on the most difficult cases."

Six Innovations That Could Prove Critical To Reforming The Health Care System <http://www.medicalnewstoday.com/articles/168961.php>
The Wall Street Journal <http://online.wsj.com/public/page/health-care-102709.html> offers a collection of stories that looks at changes in health care that could yield big responses: "Health-care innovations come in many shapes and sizes ... [including] the kind that can help reach the goal that continues to elude our policy makers: getting good care to the greatest number of people in the most cost-effective way."
The Journal looks at six innovations including changes in public policy and high technology, hospital procedures and market competition, that improve the doctor-patient relationship. It notes "one of the most promising innovations in the delivery of care isn't a technology or a new device but a simple idea: patient- and family-centered care, an approach that aims to remove the wall between medical professionals and patients, and bring the human touch back to medicine" (Landro, 10/27).
