Introduction: Sex hormones’ fluctuations during the menstrual cycle, influence asthma and lung function. Information on the changes in exercise-induced sex hormones in mid luteal phase associated with lung function changes is not available. The aim of this study was to investigate the effect of the regular aerobic exercise on the lung function indices and serum levels of sex hormones in t...
cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. however, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma. the purpose of this study was to determine the extent of change in...

Background and Objective: Obesity and body fat percentage seem to be associated with respiratory problems, although the mechanism of this correlation is not very clear. The aim of this study was to investigate the effect of 12-week HIIT training on lung function, serum leptin level and lipid profile in inactive obese men. Materials and Methods: Twenty-two inactive obese men aged 18 to 30 y...
background: respiratory problem is one of the major health hazards in dust-exposed workers; it is a major cause of morbidity and mortality all over the world. objective: to determine the prevalence of respiratory problems and lung function impairment among quarry workers in ebonyi state, nigeria. methods: respiratory problems and lung function were studied in 403 quarry workers aged 10–60 years...

Background: Lymphangioleiomyomatosis (LAM) is a progressive lungs disease that affects women at reproductive years. Sirolimus inhibits mammalian target of rapamycin (mTOR) and its administration in past studies was hopeful in treatment of patients with LAM. The aim of this study was to evaluate sirolimus therapy on lung function in LAM patients. Methods: We conducted a trial to evaluate the ef...
lung function tests were performed in 122 workers of vegetable oil refineries in tehran area. the results show an increase in respiratory impairment with age and length of exposure. among the four indices of lung function that were calculated, fev1 %fvc and fef 25-75% pfef 25-75 showed the greatest decrease with age and length of exposure, while fvc% pfvc and fev1% pfev1 were essentially within...
Abstract Background and Aim: Benzene, toluene, xylene and ethyl benzene (BTEX) are the most important aromatic compounds in petroleum products. BTEX compounds due to their high vapor pressure, easily change to gas form and mixed with ambient air. Petroleum products loading workers are exposed to these compounds by the inhalation of BTEX compounds. The aim of this study was to evaluate the ef...
Lung cancer is one of the most dangerous diseases that cause a large number of deaths. Early detection and analysis can be very helpful for successful treatment. Image segmentation plays a key role in the early detection and diagnosis of lung cancer. K-means algorithm and classic PSO clustering are the most common methods for segmentation that have poor outputs. In t...
