  1. Anaerobic threshold determination through ventilatory and electromyographics parameters.

    Electromyography and clinical neurophysiology 50(3-4):131 (2010) PMID 20552947

    The aim of present study was to compare the alterations in electromyography signs with Ventilatory Threshold (VT). Had been part of the study eight men, amateur cyclists and triathletes (25.25 +/- 6.96 years), that they had exercised themselves in a mechanical cicloergometer, a cadence of 80 RPM and...
  2. The effect of inhaling peppermint odor and ethanol in women athletes.

    Bratislavske lekarske listy 110(12):782 (2009) PMID 20196473

    We think is due to the intensity and duration of training. Referring to our results of the present study; we suggest that inhaling peppermint odor during acute intensive exercise has no significant effect on pulmonary indexes and physical performance (Tab. 4, Fig. 1, Ref. 21)....
  3. The importance of the airway. FAU - Pistolas, Philip J

    The Functional orthodontist 23(1):20 (2006) PMID 16776006

  4. The effect of hypoxia on pulmonary O2 uptake, leg blood flow and muscle deoxygenation during single-leg knee-extension exercise.

    Experimental Physiology 89(3):293 (2004) PMID 15123565

    These results suggest that factors other than O(2) delivery, possibly the diffusion of O(2,) were responsible for the lower O(2) uptake during the exercise on-transient in hypoxia....
  5. [The use of inexact reasoning method for differential diagnosis of pulmonary function].
    Li, Q Yan, and D He

    Journal of Biomedical Engineering/Shengwu Yixue... 16(4):488 (1999) PMID 12552730

    We have developped a computer-aided medical differential diagnosis system with Visual Basic. The system can identify restrictive ventilatory impairment, obstructive ventilatory impairment, mixed ventilatory impairment and normal. according to the valuse of patients' related indexed. In a retrospecti...
  6. Effect of frequency and tidal volume on pleural pressure in rabbits during high frequency ventilation.

    Lung 177(1):21 (1999) PMID 9835631

    We measured airway pressure (Paw), esophageal pressure (Pes), and costal pleural pressure (Ppl) by a rib capsule and flow and volume with a calibrated pneumotachograph. Using a closed circuit, pressures and flow were measured at varying frequencies (2-80 Hz) and tidal volumes (2-20 ml). Mean Pes and...
  7. Exercise performance in cystic fibrosis before and after bilateral lung transplantation.

    The Journal of Heart and Lung Transplantation 17(11):1104 (1998) PMID 9855450

    Exercise performance in patients with end-stage cystic fibrosis improves after lung transplantation but remains well below normal. Reduced systemic O2 extraction is an important factor limiting exercise in patients with cystic fibrosis after transplantation and may also contribute to the exercise li...
  8. Improvement with disodium cromoglycate of neutrophil phagocytosis and respiratory burst activity in a patient with hyperimmunoglobulin E syn...

    Allergy 53(11):1101 (1998) PMID 9860246

    We report a case of hyperimmunoglobulin E syndrome (HIE) complicated by neutrophil deficiency which was successfully treated with oral administration of disodium cromoglycate. A 48-year-old Japanese man with HIE developed Streptococcus pneumoniae meningitis. Laboratory tests after the meningitis rev...
  9. Evaluation of nasal patency: comparison of patient and clinician assessments with rhinomanometry.

    Acta Oto-Laryngologica 118(6):847 (1998) PMID 9870632

    We studied nasal airway patency in 254 subjects (37 women, 217 men), mean age 21 years (range 14-78) by RN and PNIF. Nasal resistance was also measured by the application of Ohm's law for parallel resistors (NRO) by estimating the unilateral resistance separately. Subjective sensation of nasal block...
  10. Lung function during moderate hypobaric hypoxia in normal subjects and patients with chronic obstructive pulmonary disease.

    Aviation, Space, and Environmental Medicine 69(10):979 (1998) PMID 9773900

    We observed a decline in forced vital capacity in some COPD patients and normal subjects greater than expected for within day variability. Spirometric changes correlated with changes in reduced maximum voluntary ventilation in the patients but not with changes in resting arterial blood gases....
