A study population of 3086 employees was identified in 18 carbon black production plants in seven European countries. Respiratory health questionnaires, spirometry, and chest radiographs were used to estimate effects on health and personal monitoring procedures were employed to measure current exposure to inspirable and respirable dust along with sulphur and carbon monoxide. The low concentrati...
BACKGROUND The value of impulse oscillometry (IOS) for bronchial provocation testing is poorly defined. We investigated the positive threshold derived from the parameters and diagnostic power of IOS for asthma with the leukotriene D(4) bronchial provocation test. METHODS We enrolled 62 subjects with asthma and 21 healthy subjects. IOS was employed to perform the leukotriene D(4) bronchial pro...
background asthma is a chronic inflammatory disease in respiratory system and obesity is another inflammatory disease which incidence rate is increasing. although, many studies have been conducted on severity of asthma and its relationship with obesity, but different results have been obtained. this study aimed to determine a relationship between asthma severity, body mass index (bmi) and pulmo...
Background & Aims: The purpose of the present study was to evaluate the effect of 8 weeks specific aquatic therapy on kyphosis angle and some pulmonary indices in male university students with kyphosis. Methods: A total of 15 males with increased normal thoracic Kyphosis (kyphosis 40 degrees, 20.70 ± 0.705 years old, height 175.5 ± 6.19 cm, weight 64.19 ± 8.23 kg) were selected. Before and afte...
Loss of sleep causes deterioration of pulmonary function and ventilatory responsiveness in normal humans and in patients with chronic obstructive pulmonary disease. To evaluate the effects of variations in sleep quality on breathing, we studied 48 healthy elderly volunteers (mean age, 70 years). Electroencephalographically derived indices of sleep quality were correlated with spirometric perfor...
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
Abstract Background Reversibility measured by spirometry in chronic obstructive pulmonary disease (COPD) is defined as an increase forced expiratory volume first second (FEV1) that both more than 12% and 200 mL above the pre-bronchodilator value response to inhaled bronchodilators. FEV1 only may not fully reverberate changes caused reduction air trapping or hyperinflation. To date, studies exam...
The purpose of this study was to determine whether the forced oscillation technique is more sensitive than spirometry to detect lung function alterations in subjects with respiratory complaints. The input impedance of the respiratory system (between 2 and 24 Hz) and maximal expiratory flows and volumes were measured in 1,255 subjects referred for routine spirometry. A questionnaire concerning r...
