Influence of pedal cadence on the respiratory compensation point and its relation to critical power
Publication date: 1 March 2015 Source:Respiratory Physiology & Neurobiology, Volume 208 Author(s): R.M. Broxterman , C.J. Ade , T. Barker , T.J. Barstow It is not known if the respiratory compensation point (RCP) is a distinct work rate (Watts (W)) or metabolic rate ( V ˙ O 2 ) and if the RCP is mechanistically related to critical power (CP). To examine these relationships, 10 collegiate men athletes performed cycling incremental and constant-power tests at 60 and 100rpm to determine RCP and CP. RCP work rate was significantly (p ≤0.05) lower for 100 than 60rpm (197±24W vs. 222±24W), while RCP V ˙ O...

Hydrogen sulfide activates the carotid body chemoreceptors in cat, rabbit and rat ex vivo preparations
This study was designed specifically to determine the effect of H2S on chemoreceptors in different species. We conducted multiunit extracellular recordings of the sinus nerve in the ex vivo carotid body preparation taken from the rat, the cat and the rabbit. As observed in the mouse carotid body, H2S donors (NaHS or Na2S) evoked qualitatively similar excitatory responses of the afferent sinus nerves of the species studied here. The excitatory effects of the H2S donors were concentration-dependent and reversible. The sinus nerve responses to H2S donors were prevented by blockade of the transmission between type I cells and ...

Developmental nicotine exposure adversely effects respiratory patterning in the barbiturate anesthetized neonatal rat
In this study we used a traditional autocorrelation function (ACF) testing its suitability as a tool to detect subtle alterations in respiratory patterning in vivo. We applied the ACF to chest wall motion tracings obtained from rat pups in the period corresponding to the mid-to-end of the third trimester of human pregnancy. Pups were drawn from two groups: nicotine-exposed and saline-exposed at each age (i.e., P7, P8, P9, and P10). Respiratory-related motions of the chest wall were recorded in room air and in response to an arousal stimulus (FIO2 14%). The autocorrelation function was used to determine measures of breathin...

Neonatal hyperoxia up regulates cough reflex in young rabbits
Publication date: 1 March 2015 Source:Respiratory Physiology & Neurobiology, Volume 208 Author(s): Silvia Varechova , Bruno Demoulin , Anne Laure Leblanc , Laurianne Coutier , Iulia Ioan , Claude Bonabel , Cyril Schweitzer , François Marchal A link between cough in childhood and neonatal exposure to hyperoxia following preterm birth has been suggested. The hypothesis is tested that neonatal exposure to hyperoxia is associated with long term up regulation of cough. Airway hyperresponsiveness is also investigated because it is a frequent finding in children born preterm and may be linked to cough. Thirty nine youn...

Sleep disordered breathing and acute mountain sickness in workers rapidly transported to the South Pole (2835m)
Conclusion AMS was not significantly associated with sleep architecture changes or increased AHI. However, AHI sharply increased at South Pole (19/38 participants) primarily due to central apneas. Those developing AMS were more likely to have experienced previous problems at altitude and reported living at lowland altitudes within the 3 months prior to rapid transport to the South Pole than those without AMS.

Automatic classification of canine PRG neuronal discharge patterns using K-means clustering
This report presents a method that automatically classifies neurons according to their discharge patterns and derives an average subgroup contour of each class. It is based on the K-means clustering technique and it is implemented via SigmaPlot User-Defined transform scripts. The discharge patterns of 135 canine PRG neurons were classified into seven distinct subgroups. Additional methods for choosing the optimal number of clusters are described. Analysis of the results suggests that the K-means clustering method offers a robust objective means of both automatically categorizing neuron patterns and establishing the underly...

Hypoxia switches episodic breathing to singlet breathing in red-eared slider turtles (Trachemys scripta) via a tropisetron-sensitive mechanism
Publication date: 1 February 2015 Source:Respiratory Physiology & Neurobiology, Volume 207 Author(s): Stephen M. Johnson , Ashley R. Krisp , Michelle E. Bartman Hypoxia-induced changes in the chelonian breathing pattern are poorly understood. Thus, breathing was measured in freely swimming adult red-eared slider turtles breathing air prior to breathing nitrogen for 4h. Ventilation increased 10-fold within 10min due to increased breath frequency and tidal volume. Breaths/episode decreased by ∼50% within after 1h of hypoxia while the number of singlet breaths increased from 3.1±1.6singlets/h to a maximum of 66.1...
