Tetrahydrobiopterin analogues with NO-dependent pulmonary vasodilator properties [PDF]

, 2011
Reduced NO levels due to the deficiency of tetrahydrobiopterin (BH4) contribute to impaired vasodilation in pulmonary hypertension Due to the chemically unstable nature of BH4 it was hypothesised that oxidatively stable analogues of BR, would be able to ...

Pulmonary Function in Pulmonary Sarcoidosis

Journal of Clinical Medicine, 2023
The pulmonary function test (PFT) has been widely used in sarcoidosis. It may vary due to the severity, extent, and the presence of complications of the disease. Although the PFT of most sarcoidosis patients is normal, there are still 10–30% of cases who may experience a decrease in the PFT, with a progressive involvement of lungs.

Exercise Capacity, Ventilatory Response, and Gas Exchange in COPD Patients With Mild to Severe Obstruction Residing at High Altitude

Frontiers in Physiology, 2021
BackgroundExercise intolerance, desaturation, and dyspnea are common features in patients with chronic obstructive pulmonary disease (COPD). At altitude, the barometric pressure (BP) decreases, and therefore the inspired oxygen pressure and the partial ...

Cardiopulmonary exercise testing and pulmonary function testing for predicting the severity of CTEPH

BMC Pulmonary Medicine, 2021
Background Cardiopulmonary exercise testing (CPET) and pulmonary function testing (PFT) are noninvasive methods to evaluate the respiratory and circulatory systems. This research aims to evaluate and monitor chronic thromboembolic pulmonary hypertension (

Long-term variability of impulse oscillometry and spirometry in stable COPD and asthma

Respiratory Research, 2022
Background While optimizing spirometry is a challenge for lung function labs, long-term variability if any between IOS (impulse oscillometry) parameters and spirometry is not clearly known in stable COPD (chronic obstructive pulmonary disease) and ...

Exercise intolerance in post-coronavirus disease 2019 survivors after hospitalisation

ERJ Open Research, 2023
Rationale Post-coronavirus disease 2019 (COVID-19) survivors frequently have dyspnoea that can lead to exercise intolerance and lower quality of life. Despite recent advances, the pathophysiological mechanisms of exercise intolerance in the post-COVID-19

Variation of PetCO2 during incremental exercise and severity of IPAH and CTEPH

BMC Pulmonary Medicine, 2022
Background and objective End-tidal PCO2 (PetCO2) patterns during exercise testing as well as ventilatory equivalents for CO2 have been reported for different pulmonary vascular diseases but seldomly for the significant differences in exercise response ...

Pulmonary function tests [PDF]

Rheumatology, 2008
Systemic sclerosis-associated interstitial lung disease (SSc-ILD) is the leading cause of morbidity and mortality in SSc patients. In autopsy studies, up to 70% of the SSc patients show histological evidence of lung involvement. In surgical lung biopsies from SSc-ILD patients, a pattern of non-specific interstitial pneumonia is present in a majority ...

Diphenylhydantoin and Pulmonary Function [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1979
SummaryThirty-nine epileptic patients underwent pulmonary function testing. Twenty-one of these patients, ranging in age from 16 to 44 years, had taken diphenylhydantoin (DPH) for 2 to 17 years. Eighteen patients, who had taken other anticonvulsants for similar time periods served as controls.
