CT-guided radiofrequency ablation (RFA) is effective in easing the symptoms of lung tumors that cannot be removed by surgery, and enhancement pattern and changes in the size of the tumor as shown on CT are the most important factors for determining whether that ablation has been successful, according to a pair of independent studies in the October 2004 issue of the American Journal of Roentgenology.
For the first study, researchers from Casertas S. Sebastiano Hospital in Italy analyzed 33 patients with malignant lung cancer who could not undergo surgery and opted for CT-guided RFA instead. No major complications occurred for any patient during RFA, and all RFA sessions were deemed successful at follow-up CT.
According to Giuseppe Belfiore, MD, lead author of the article, the study was prompted by the feeling that an alternative to the usual therapies for lung cancer was strongly needed. "We see too many lung cancer patients who, inoperable for a number of different reasons, are left with few chances to obtain an effective palliation," said Dr. Belfiore. "We believe that a powerful alternative/complementary option is now available, although we believe that the full potential of RFA is still to be assessed. For sure, RFA allows a better quality of life for many inoperable patients," Dr. Belfiore added.

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...
