New techniques for management of the crooked nose.
The crooked or twisted nose results from a complex deformity of the bony pyramid, the upper and lower cartilaginous vaults, and the septum and causes functional and aesthetic problems. The forces of scar contracture coupled with long-standing cartilage deformation may make the crooked nose resistant to conventional surgical intervention. The middle vault of the nose may exhibit deformities that...
متن کامل'Electronic nose'--new condition monitoring devices for environmental applications.
The responses of individual odour sensors combined into an array, where each sensor possesses slightly different response selectivity and sensitivity towards the sample odours, when combined by suitable mathematical methods, can provide information to discriminate between many sample odours (Pearce et al., 2002). Arrays of gas and odour sensors, made using different technologies, are finding th...
متن کاملComparision of Electronic Nose with Biological Nose
ELECTRONIC Noses (EN), in the broadest meaning, are instruments that analyze gaseous mixtures for discriminating between different (but similar) mixtures and, in the case of simple mixtures, quantify the concentration of the constituents. ENs consists of a sampling system (for a reproducible collection of the mixture), an array of chemical sensors, Electronic circuitry and data analysis softwar...
متن کاملIs a nose just a nose?
A little over a decade ago, passive humidifiers, ¦^^ commonly called "artificial noses," were rele¬ gated to short-term use, typically less than 24 h. Improvements in design, coupled with careful clini¬ cal investigations, have proven that in select patients, passive humidifiers can be used safely for several days.15 The definition oi several is currently debat¬ able, but evidence for up to 5 d...
متن کاملResponses to putative second messengers and odorants in water nose olfactory neurons of Xenopus laevis.
Using the whole-cell mode of the patch-clamp technique, we attempted to record inward currents in response to cAMP, inositol 1,4, 5-trisphosphate (IP(3)) and odorants from sensory neurons in the olfactory epithelium of the Xenopus laevis lateral diverticulum (water nose). Dialysis of 100 microM of IP(3) induced inward currents, while dialysis of 1 mM of cAMP into olfactory neurons did not induc...
