In Drosophila, the amidated neuropeptide pigment dispersing factor (PDF) is expressed by the ventral subset of lateral pacemaker neurons and is required for circadian locomotor rhythms. Residual rhythmicity in pdf mutants likely reflects the activity of other neurotransmitters. We asked whether other neuropeptides contribute to such auxiliary mechanisms. We(More)
The safety, efficacy, and outcome of long-term patient-triggered synchronized assisted ventilation in infants (SAVI) was studied in very low birthweight infants (450 to 1250 g) with uncomplicated respiratory failure. Synchronization was accomplished by modified thoracic impedance technology using standard neonatal cardiorespiratory monitors with the output(More)
We compared the McGrath® Series 5 videolaryngoscope with the Macintosh laryngoscope in a simulated difficult airway, using manual in-line stabilisation in 88 anaesthestised patients of ASA physical status 1-2. The primary outcome was laryngoscopic view. Secondary outcomes included rates of successful tracheal intubation and complications. A Cormack and(More)
An experimental autoimmune model was used to study effects of nerve growth factor deprivation on the peptide content of sensory neurones and on pain sensitivity. Rats exposed during development to anti-nerve growth factor antibodies showed an increased threshold towards nociceptive stimuli. These animals also showed a significant decrease in substance P(More)
We characterised histamine H(1) receptor antagonism by cetirizine and its enantiomers on isolated guinea pig ileum and trachea. Competitive or mixed (competitive and apparent noncompetitive) antagonism profiles were observed. The order of potency was: chlorpheniramine> or =mepyramine>levocetirizine>cetirizine> or =terfenadine>loratadine>dextrocetirizine.(More)
