Electronic nose detects pneumonia in critically ill patients
According to a team of researchers from University of Pennsylvania School of Medicine, an electronic nose - a relatively new version of a sensor previously used in the food, wine and perfume industries - can quickly and accurately diagnose pneumonia in critically ill, mechanically ventilated patients. The results will be presented at the CHEST 2002 Annual Meeting Tuesday, November 5th in San Diago.
"We wanted to further explore using the e-nose after the exciting results of an initial study we conducted back in 1997 with only 20 patients," said C. William Hanson, III, MD, associate professor of Anesthesia, Surgery and Internal Medicine, and lead author of the study. When it comes to lower pulmonary infections, especially in critically ill patients, time is of the essence for disease control. "Rather than waiting two to three days for the results of a bacterial culture or relying on chest X-rays which arent always accurate, the e-nose can give us a head start toward a proper diagnoses. We could avoid over-prescribing powerful antibiotics which are usually given to patients while were waiting for their test results, even though we dont know if they actually need them," adds Hanson.

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...
