BACKGROUND Electronic nose (E-nose) technology has been successfully used to diagnose a number of microbial infections. We have investigated the potential use of an E-nose for the diagnosis of ventilator-associated pneumonia (VAP) by detecting micro-organisms in bronchoalveolar lavage (BAL) fluid in a prospective comparative study of E-nose analysis and microbiology. MATERIALS AND METHODS BAL...

There have been few longitudinal studies on sick building syndrome (SBS), which include headache, fatigue, and runny nose. We considered effect of sick building syndrome with illnesses like headache, fatigue and runny nose. Thus, we designed a questionnaire and asked from male of dormitory residence. Questions of the questionnaire were more about known symptoms of buildings (headache, fatigue, ...

The current recommendation for resuscitation of infants is to blow air into both the nose and mouth. We have observed that mothers cannot cover both the nose and mouth of their infants. We compared postmortem tracheal and esophageal air entry by using the nose, combined nose and mouth, and mouth routes in eight infants. Air entry into the trachea occurred at lower pressures (P < 0.05) via a nos...

IMPORTANCE Many valuable classification schemes for saddle nose have been suggested that integrate clinical deformity and treatment; however, there is no consensus regarding the most suitable classification and surgical method for saddle nose correction. OBJECTIVES To present clinical characteristics and treatment outcome of saddle nose deformity and to propose a modified classification syste...

The aim of the present study was to develop an electronic nose for the quality control of red meat. Electronic nose and bacteriological measurements are performed to analyse samples of beef and sheep meat stored at 4°C for up to 15 days. Principal component analysis (PCA) and support vector machine (SVM) based classification techniques are used to investigate the performance of the electronic n...

Electronic noses and tongues can utilize noise data taken at the output of a chemical sensor. It is shown that even one single sensor may be suf®cient for realizing an electronic nose or tongue. # 2000 Elsevier Science B.V. All rights reserved.

metastatic   tumors in the nose and paranasal sinuses are infrequent. the origin of this metastatic tumors are often renal cell carcinoma. we present one case of metastatic renal cell carcinoma   to the nose and paranasal sinuses ,4 years after initial nephrectomy and diagnosis of stage t1n0m0 clear cell carcinoma. the patient complained of nasal obstruction and recurrent epistaxis   who was tr...

This paper reviews the range of sensors used in electronic nose (e-nose) systems to date. It outlines the operating principles and fabrication methods of each sensor type as well as the applications in which the different sensors have been utilised. It also outlines the advantages and disadvantages of each sensor for application in a cost-effective low-power handheld e-nose system.
