—Deploying home access points (AP) is hard. Untrained users typically purchase, install, and configure a home AP with very little awareness of wireless signal coverage and complex interference conditions. We envision a future of autonomous wireless network management that uses the Internet as an enabling technology. By leveraging a P2P architecture over(More)
Exhaled nitric oxide (FENO) may provide a tool for identifying infants at risk of developing allergic disease in childhood. In infants there is no standardized collection technique; however, the easiest method is to measure FENO during tidal breathing. In this study we investigated various methodological issues for tidal breathing (TB) FENO in infants.(More)
ISSUE ADDRESSED There are moves to ban smoking in outdoor areas of pubs, restaurants and cafes. Some argue that this is unnecessary as exposure to second hand smoke (SHS) is minimal. The aim of this study was to determine potential exposure of patrons to SHS in outdoor areas of eating and drinking venues. METHODS Concentrations of fine particulate matter(More)
BACKGROUND Raised exhaled nitric oxide (Feno) levels have been associated with asthma. However, we have found that in children, Feno was increased in atopic children with increased airway responsiveness (AR), and this was independent of a diagnosis of asthma. STUDY OBJECTIVES The current study was designed to test the hypothesis that in adults there is no(More)
BACKGROUND Exhaled nitric oxide (FE(NO)) is raised in asthmatic children, but there are inconsistencies in the relationship between FE(NO) and characteristics of asthma, including atopy, increased airway responsiveness (AR), and airway inflammation. The aim of this study was to investigate the relationship between FE(NO) and asthma, atopy, and increased AR(More)
BACKGROUND The fractional concentration of nitric oxide (NO) in exhaled breath (FeNO) is increased in asthma. There is a general assumption that NO synthase (NOS) 2 in epithelium is the main source of NO in exhaled breath. However, there is no direct evidence to support the assumption and data from animal models suggest that non-inducible NOS systems have(More)
RATIONALE Progressive lung damage in cystic fibrosis (CF) starts in infancy, and early detection may aid preventative strategies. OBJECTIVES To measure lung function in infants with CF diagnosed by newborn screening and describe its association with pulmonary infection and inflammation. METHODS Infants with CF (n = 68, 6 weeks to 30 months of age) and(More)
There is growing interest in investigating compounds of exhaled breath condensates (EBC) as potential noninvasive markers of airways disease processes. Some of these markers have the potential to provide information on the early stages of disease. In this paper, we present a method for collecting EBC during both oral and nasal breathing in infants.(More)
Malignant mesothelioma (MM) of the pleura or peritoneum is a universally fatal disease attracting an increasing range of medical interventions and escalating healthcare costs. Changes in survival and the factors affecting survival of all patients ever diagnosed with MM in Western Australia over the past five decades and confirmed by the Western Australian(More)
Exhaled nitric oxide (eNO) is elevated in patients with inflammatory pulmonary diseases and it has attracted increasing interest as a simple, noninvasive marker of airway inflammation. Little is known, however, about factors that might affect eNO in healthy subjects. We measured eNO in 157 healthy 7- to 13-yr-old children (mean 9.7 yr, 77 girls), with no(More)
