Cochlear microphonic (CM) potentials were recorded from the bat, Pteronotus p. parnellii during tethered flight and during simulated flight on a pendulum. For each emitted signal the frequency of the ca. 61 kHz constant frequency (CF) component was compared with the frequency response characteristics of the animals's ear. The majority of "resting pulses'(More)
We report the anaesthetic management of a 3-year-old-child with microvillus inclusion disease undergoing isolated small bowel transplantation. He required long-term total parenteral nutrition which was complicated with numerous episodes of catheter related sepsis. This resulted in thrombosis of the major blood vessels which critically restricted vascular(More)
The uptake of sevoflurane and nitrous oxide (N(2)O) was characterized during the mask induction of anesthesia in healthy children. We assessed concentration and second gas effects by determining the influence of two different inspiratory N(2)O concentrations on the rate at which the estimated alveolar concentration (FA) increased to the inspired gas(More)
In the laboratory the neotropical bat, Pteronotus p. parnellii of Jamaica W.I., will readily capture free flying and tethered insects. It will also attack a stationary mechanical insect model when its wing-like parts are rapidly moving. On the basis of our observations we conclude that: 1. P. parnellii are attracted to flying insects and recognition of(More)
Fresh, frozen sections of the photoreceptor layer of the compound eye of the moth Galleria have been examined by microspectrophotometry, using 4 times 8 mum measuring beams that sampled from approximately two to four rhabdoms. The principal visual pigment absorbs maximally at 510 nm (P510), and on irradiation is converted to a thermally stable,(More)
We present a case of an infant with severe macroglossia, hypoglycaemia and inguinal hernia associated with hepatoblastoma (Beckwith-Wiedemann syndrome) in which a laryngeal mask airway (LMA) was useful to secure the airway during central line insertion. Carbon dioxide monitoring through LMA proved effective to assess airway patency during positioning for(More)
The assessment of apnea and asynchronous breathing requires the application of a facemask connected to a pneumotachograph and inductive transducer bands placed around the chest wall. These contact devices may alter the breathing pattern and are difficult to implement, especially in infants and children. This study validates a contactless image-processing(More)
We present a case of surgery in a 2-month-old infant of the Jehovah's Witness (JW) faith weighing 2.8 kg scheduled for left upper lobectomy because of congenital lobar emphysema. He presented with physiological anaemia (haematocrit 33.8%) in accordance with his age. Because of the relative emergency of surgery, a short erythropoietin course was instituted.(More)
We sought to quantify the autocorrelation properties and fractal dynamics of interbreath interval (IBI) variability to see if short-term airway pressure (Paw) increases affected scaling behaviour. Data were collected in anaesthetised children at basal (Ba), medium (Me) and high (Hi) Paw. Consistent with short-range dependence, the autocorrelation function(More)
