  1. Impact of inferior turbinate hypertrophy on the aerodynamic pattern and physiological functions of the turbulent airflow - a CFD simulation ...

    Rhinology 48(2):163 (2010) PMID 20502754

    In the healthy nose, the main respiratory air stream occurs mainly in the middle of the airway, accompanied by a diffused pattern of turbulent flow on the surface of the nasal mucosa. The peak value of turbulent flow is found in the functional nasal valve region. However, this aerodynamic flow patte...
  2. Pre and post menstrual peak flow rates and symptoms amongst patients with bronchial asthma.

    The Journal of the Association of Physicians of... 58:331 (2010) PMID 21121101

  3. Interaction effects of time of day and sub-maximal treadmill exercise on the main determinants of blood fluidity.

    Clinical Hemorheology and Microcirculation 45(2-4):177 (2010) PMID 20675898

    The purpose of this study was to investigate the effects of time of day on responses of the main determinants of blood rheology to acute endurance exercise. Ten healthy male subjects (age, 26.9 +/- 5.5 yr) performed two bouts of running at 65% of VO2peak for 45 min on a motorised treadmill in the mo...
  4. Non-invasive positive pressure ventilation for a severe legionella pneumonia case.

    Tuberkuloz ve toraks 57(3):348 (2009) PMID 19787476

    Legionella pneumonia has a serious clinical course and requires treatment at intensive care unit. The need for mechanical ventilation is one of the determinants of prognosis. Mortality rate is higher in patients treated with mechanical ventilation. Non-invasive positive pressure ventilation (NPPV) p...
  5. [Regulation of respiration: visceral and behavioural components].

    Uspekhi fiziologicheskikh nauk 38(2):26 (2007) PMID 17578017

    The review segregates two aspects of respiration regulation: autonomous respiration regulation as a visceral function ensuring metabolic needs of a body by maintaining stability of own respiratory environment, on the one hand, and behavioural regulation of respiration under control of the volitional...
  6. [Relationship of stress index with lung recruitment and gas exchange in dogs with acute respiratory distress syndrome].

    Zhonghua jie he he hu xi za zhi = Zhonghua jieh... 29(8):554 (2006) PMID 17074271

    At b = 1 without RM, the PEEP was (5.0 +/- 3.0) cm H2O, the RV was (27 +/- 15) ml, and the RV increased to (166 +/- 84) ml significantly at b = 1 after RM [PEEP (10.8 +/- 2.3) cm H2O (1 cm H2O = 0.098 kPa), q = 3.18, P < 0.01]. At 1.1 < b < 1.3 after RM, the PEEP was (16.8 +/- 1.1) cm H2O and the RV...
  7. Thermodilution versus inert gas rebreathing for estimation of effective pulmonary blood flow.

    Critical Care Medicine 28(1):51 (2000) PMID 10667498

    The RB method is a promising method for simultaneous noninvasive estimation of Qep and functional residual capacity in mechanically ventilated patients. However, further investigations are needed to evaluate potential problems of the method before it can be recommended for clinical purposes....
  8. Cardiopulmonary and CD4 cell changes in response to exercise training in early symptomatic HIV infection.

    Medicine & Science in Sports & Exercise 31(7):973 (1999) PMID 10416558

    Approximately 61% of exercise-assigned participants complied (> 50% attendance) with the exercise program, and analyses of exercise relapse data indicated that obesity and smoking status, but not exercise-associated illness, differentiated compliant from noncompliant exercisers. Compliant exercisers...
  9. Developmental components of resting ventilation among high- and low-altitude Andean children and adults.

    American Journal of Physical Anthropology 109(3):295 (1999) PMID 10407461

    1) the resting ventilation (ml/kg/min) of high-altitude natives is markedly higher than that of low-altitude natives; 2) the age decline of ventilation is similar in both lowlanders and highlanders, but the starting point and therefore the age decline are much higher at high altitude; 3) the resting...
  10. Reversible and irreversible airflow obstruction as predictor of overall mortality in asthma and chronic obstructive pulmonary disease.

    American Journal of Respiratory and Critical Ca... 159(4):1267 (1999) PMID 10194175

    We tested the hypothesis that reversibility to corticosteroid and bronchodilator is not an independent predictor of prognosis, but merely reflects a component of the maximal attainable lung function, which is the best spirometric predictor of survival. During a 6-yr period (1983-1988), 1,586 subject...
