BACKGROUND Securing a diagnosis of ovarian cancer and establishing means to predict outcomes to therapeutics remain formidable clinical challenges. Early diagnosis is particularly important since survival rates are markedly improved if tumour is detected early. METHODS Comprehensive miRNA profiles were generated on presurgical plasma samples from 42 women(More)
Parkinson's disease (PD) is characterized by movement disorders, including bradykinesia. Analysis of inherited, juvenile PD, identified several genes linked via a common pathway to mitochondrial dysfunction. In this study, we demonstrate that the larva of the Drosophila parkin mutant faithfully models the locomotory and metabolic defects of PD and is an(More)
The aim of the present study was to determine survival rates of obstructive sleep apnoea patients treated with continuous positive airway pressure (CPAP) and to investigate the prognostic value of pretreatment lung function and pulmonary haemodynamics. Two hundred and ninety-six patients, exhibiting > or = 20 apnoeas plus hypopnoeas per hour of sleep, were(More)
In chronic respiratory diseases, especially chronic obstructive pulmonary disease (COPD) pulmonary arterial hypertension is generally mild to moderate and the necessity for treating it can, therefore, be questioned. In fact, pulmonary hypertension, even when modest, may worsen markedly during acute episodes, exercise and sleep. These acute increases in mean(More)
There have been very few studies assessing the long-term physiological effects of nasal continuous positive airway pressure (CPAP) for the obstructive sleep apnoea syndrome. We therefore investigated prospectively the evolution of lung function, arterial blood gases and pulmonary haemodynamics in patients with this syndrome treated with CPAP. Sixty five(More)
The validity of a new method for measuring thoracic gas volume (TGV) was studied in 69 children, 4-16 yrs old, including twelve normal children and 57 children with an obstructive (n = 38) or restrictive (n = 19) respiratory disease. The method consisted of applying very slow (0.05 Hz) sinusoidal variations of ambient pressure around the body (delta Pam =(More)
There has been extensive research on clustering algorithms for sensor applications. Those algorithms allow tradeoffs between energy consumption, convergence time, and adaptability to changing network topologies. However, many of these algorithms may not function well in deployed UGS networks because previous analyses of those algorithms used simplified(More)
