"This is extremely fast if Harry is to bring water into his gills through respiratory power alone.
Thus, recent evidence indicative of highly efficient flight capabilities [2], [6], [7], [16], [17] brings forward interesting questions regarding the structure and function of the respiratory system that powered the metabolic demands of pterosaurian flight.
Although all of our results were robust to the choice of transmission definition ('Results' not shown), defining transmission by viral isolation alone slightly increased predictive power for direct contact experiments, and slightly decreased predictive power for respiratory droplet experiments.
High-frequency power (HFP) reflects effects on respiratory sinus arrhythmia, an index of parasympathetic nerve activity, whereas low-frequency power (LFP) reflects effects on both sympathetic and parasympathetic nerves [ 21].
Results from the stress testing database show that information on respiratory frequency produces HF power estimates which closely resemble those from the simulations which exhibited lower SD.
To power the respiratory chain under energy-limited conditions, mycobacteria switch to alternative primary dehydrogenases to provide reducing equivalents for respiration.
The power spectrum was not assessed during exercise, and environmental factors that can disturb sympathovagal balance and the influence of respiratory rate on the power spectrum were not accounted for.
For a condition with a lower prevalence of 15% (e.g. some respiratory conditions), having 80% power to detect a reduction of 5% would require a sample of 1450.
However, even with a lower overall mortality, we detected a statistically significant association between both LIS and Berlin severity and both in-hospital death and more prolonged respiratory failure, demonstrating sufficient power.
Of the five studies that used a protocol designed to enhance respiratory muscle strength and power, four showed no change in exercise VE after training [ 11, 12, 15, 18], and one showed an increase that just failed to reach significance (P= 0.051, [ 17].
