OBJECTIVE To investigate the tolerance, compliance and problems associated with usage of nasal continuous positive airway pressure (CPAP) by pregnant women with sleep disordered breathing (SDB). PATIENTS AND METHOD Twelve pregnant women diagnosed with SDB received polysomnography (PSG) at entry, CPAP titration, repeat PSG at 6 months gestation (GA) and(More)
The salience of a short conspecific song phrase versus a long one or a short heterospecific song phrase was tested in females of the common domesticated canary (Serinus canaria). All phrases were computer-edited. The copulation solicitation displays (CSD) served as an index of female responses. The results support the hypothesis that female canaries are(More)
The purpose of this study was to investigate the association between low blood pressure (BP) with mild symptoms of orthostatism, sleep-disordered breathing (SDB) and tilt test results in 7- to 12-y-old children. A retrospective chart review of 301 children, ages 7 to 12 y, was initially performed to evaluate the frequency of abnormal BP measurements. Then a(More)
The extent of syllable variation tolerance was tested using synthetic homologue syllables. A synthetic copy of a common syllable type of cirl bunting Emberiza cirlus song was used as control. Homologue syllables, in the same frequency range but shorter or longer, were created by multiplying (2/3, 5/3, 7/3) the time scale of the control syllable. By this way(More)
Female domesticated canaries (Serinus canaria) respond to conspecific song with copulation solicitation display (CSD) between 22 and 27 days after their first offspring has hatched. This period could be used to investigate the acoustical preferences of female canaries. This non-invasive method respects the natural reproductive cycle and could be an(More)
We tested the sexual responsiveness of female canaries,Serinus canaria, to two sets of different types of male conspecific songs. In each set, three of the male songs had been recorded in a young bird which was isolated at an early age from conspecifics. Each bird was recorded during three stages of the song ontogeny (early plastic songs, late plastic songs(More)
