Related Articles An Electronic Nose in the discrimination of patients with non-small cell lung cancer and COPD. Lung Cancer. 2008 Sep 30; Authors: Dragonieri S, Annema JT, Schot R, van der Schee MP, Spanevello A, Carratú P, Resta O, Rabe KF, Sterk PJ BACKGROUND: Exhaled breath contains thousands of gaseous volatile organic compounds (VOCs) that may be used as non-invasive markers of lung disease. The Electronic Nose analyzes VOCs by composite nano-sensor arrays with learning algorithms. It has been shown that an Electronic Nose can distinguish the VOCs pattern in exhaled breath of lung cancer patients from healthy controls. We hypothesized that an Electronic Nose can discriminate patients with lung cancer from COPD patients and healthy controls by analyzing the VOC-profile in exhaled breath. METHODS: 30 subjects participated in a cross-sectional study: 10 patients with non-small cell lung cancer (NSCLC, [age 66.4+/-9.0, FEV(1) 86.3+/-20.7]), 10 patients with COPD (age 61.4+/-5.5, FEV(1) 70.0+/-14.8) and 10 healthy controls (age 58.3+/-8.1, FEV(1) 108.9+/-14.6). After 5min tidal breathing through a non-rebreathing valve with inspiratory VOC-filter, subjects performed a single vital capacity maneuver to collect dried exhaled air into a Tedlar bag. The bag was connected to the Electronic Nose (Cyranose 320) within 10min, with VOC-filtered room air as baseline. The smellprints were analyzed by onboard statistical software. RESULTS: Smellpr ...

From rocket science to brain surgery: a device designed to sniff out leaks on the space shuttle may soon guide surgeons as they operate on cancer patients. The ENose was originally developed by NASA's Jet Propulsion Laboratory in Pasadena, California, to detect low-level leaks of ammonia in shuttles. It is based on polymer films whose electrical conductivity varies as they encounter different substances. Now its creators believe the ENose could act as a highly sensitive detector of the characteristic compounds produced by cancer cells. ...

Swirling a mouthwash around your mouth may really make your breath smell sweeter, according to a review by the Cochrane Collaboration, a body of scientists that assess medical evidence. In their report, released this week, the scientists reviewed five research trials involving 293 people. Among their findings: * Antibacterial mouth rinses containing the antibacterial chemicals chlorhexidine and cetylpyridinium were better than placebos at making breath less smelly; * So were mouth rinses containing chlorine dioxide and zinc, which work by neutralizing the chemicals in breath that make it smelly -- sulfur compounds such as hydrogen sulphide; * Though the two categories both performed well, a potential drawback to the chlorhexidine ones were that mouths and teeth were temporarily stained and the sense of taste was temporarily altered; * For all the excited articles they inspire in the press, so-called "Electronic noses" are not as good at assessing the offensiveness of breath as the good old human Nose, the team concluded -- and thus the human type should remain the "gold standard" for such tests.  Want to learn more about bad breath?

US shipping ports receive about 6 million cargo containers each year. Officials would like to be able to check each one for smuggled nuclear material, but today's detectors cannot process such numbers in a reasonable time. These devices typically require an officer to search inside each container. The gamma rays produced by radioactive materials can pass through containers relatively easily, but uranium produces only small amounts of such radiation. Joseph Farmer and colleagues at the Lawrence Livermore National Laboratory in California have produced a new detector sensitive even to low levels of gamma radiation. Their device is set to speed up screening times. It doesn't directly detect gamma rays themselves, but instead looks for the hydrogen peroxide generated when the rays interact with water. The detector consists of an "Electronic Nose" chip coated with a thin layer of water that is condensed onto its surface. When gamma rays strike water molecules in that layer the Nose chip detects any hydrogen peroxide formed. The inventors say that as well as being more sensitive their design can pick up a wider range of gamma ray energies than conventional detectors.

Instruments aboard a Qantas airliner warned of a glitch in its stabilization system when it suddenly rose and plunged, tossing unbelted passengers to the ceiling and injuring more than 70 people, Australian investigators said Wednesday. The A330-300 was carrying 303 passengers and 10 crew from Singapore to the Western Australian city of Perth, and was nearing its destination Tuesday when it experienced the sudden altitude changes while flying at 37,000 feet. The plane made an emergency landing in Learmonth, Western Australia. Passenger Jim Ford, of Perth, said he thought he was about to die as he watched people being flung around the cabin. "It was horrendous, absolutely gruesome, terrible, the worst experience of my life," he said after being transferred to Perth airport following the incident. Air Transport Safety Bureau investigators quarantined the flight data recorder and cockpit voice recorder and planned to interview crew and passengers. Julian Walsh, director of the bureau's aviation safety investigation, told reporters that the pilots received Electronic messages "relating to some irregularity with the aircraft's elevator control system." That system helps keep the plane stable and level in flight. The aircraft then "departed level flight," and climbed approximately 300 feet, he said. "The crew had initiated the non-normal checklist response actions. The aircraft is then reported to have abruptly pitched Nose down," Wals ...

Department of Eagles is usually referred to as a side project for Grizzly Bear’s Daniel Rossen, but he’s now released just as many LPs for each, and his collaboration with Fred Nicolaus (the other half of DOE) actually predates Grizzly Bear. Those familiar with DOE’s last full-length, The Cold Nose, may be surprised by the slightly new sound. The quirky, Electronic projects on Nose are no more—In Ear Park is an alt-folk-pop album through and through, sticking with guitars, banjos, pianos, and the like. But don’t think that they’re becoming dull and predictable—while song structures can be mapped out after repeated listens, the route they take to get to the end is usually surprising, even if it’s not always satisfying.The album opens with the title track, something of a lo-fi folk waltz dream. It’s a track dedicated to Rossen’s late father, but it could have been about pretty much anything and it would have worked. There’s some richly subdued instrumental work here, as the fluttering, twingey acoustic guitar meets up with a saloon piano and some oddly-timed percussion. Knowing what the song is about adds to its clout. “If you listen/You'd hear the waves,” followed by, “Oh, we all forgot... ...
