During the normalization phase of COVID-19 epidemic, it is gradually reverted to use building space, especially for office. Prevention airborne pollutant has emerged as a major challenge. Ventilation strategies can mitigate spread disease in indoor environment, such increasing ventilation rate, modifying mode, etc. The larger rate lead higher energy consumption may not effectively reduce infect...

conclusions treatment of neonatal respiratory failure with high rate mechanical ventilation may reduce some complications. results intraventricular hemorrhage (ivh) and air leak (e.g. pneumothorax) were less in hfppv group than conventional group (p = 0.012 and p = 0.038). the mean time needed for mechanical ventilation was lower in hfppv group, but this difference was not statistically signifi...

results in terms of radon and thoron emissions, travertine and plaster were found to be the most appropriate and inappropriate covering for walls, respectively. furthermore, granite and travertine were discovered to be inappropriate materials for flooring, while plastic floor covering was found suitable. natural ventilation performed better for radon, while artificial ventilation worked better ...

administration of endotracheal surfactant is potentially the main treatment for neonates suffering from rds (respiratory distress syndrome), which is followed by mechanical ventilation. late and severe complications may develop as a consequence of using mechanical ventilation. in this study, conventional methods for treatment of rds are compared with surfactant administration, use of mechanical...

Background: This study was targeted toward comparing volume-guaranteed (VG) ventilation with conventional pressure-controlled (PC) ventilation in preterm infants with respiratory distress syndrome (RDS) in terms of the facilitation of weaning and extubation and occurrence of complications, such as pneumothorax, intraventricular hemorrhage (IVH), retinopathy of prematur...

introduction: it has been shown that joint click, an initial and common finding in internal derangement (id), respond to neither conservative treatment nor surgical intervention. this raises the question as to whether it must be treated in the absence of other pertinent signs and symptoms, so the aim of this study was to investigate and compare the mri findings of tmj in both normal subjects an...

Introduction: Tuberculosis (TB), with different types of respiratory tract involvements, has a high rate of mortality all around the world. Endobronchial involvement, which is a slightly common tuberculous infection, requires special attention due to its severe complications such as bronchostenosis. Aim of study of this study was describes, one type of pulmonary tuberculosis with less diagnosed...
