objectives: obstructive sleep apnoea (osa) is a potentially life‑threatening condition in which there is a periodic cessation of breathing (for 10 sec or longer) that occurs during sleep in the presence of inspiratory effort. the aim of the study was to assess volumetric and dimensional differences between osa patients and normal individuals in the upright posture. material and method: the pres...

this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...

Introduction: This study aims at examining the difference of pharyngeal airways in patients with different occlusion postures, hoping to im‌prove diagnostic methods and provide a stable treatment plan for orthodontic patients. Materials and Methods: The data were ga-thered through CBCT radiographies of patients from a specialized center for radiology. In each occlusion group according to the p...

  Abstract:   Background: The most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. The differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. Caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. The...

Introduction: Hypertrophied tonsils and adenoids may cause upper airway obstruction and cardio-pulmonary complications due to pulmonary arterial hypertension. The aim of this study was to determine the correlation between mean pulmonary arterial pressure (mPAP) and selected adenotonsilar hypertrophy indexes. Materials and Methods: Thirty two patients with upper-airway obstruction resulting ...

results sore throat was recorded in 32.9% of patients with lma and 44.2% of intubated patients, but it was not statistically significant (fisher’s exact test = 0.158). hoarseness was recorded in 3.5% of patients with lma and 24.4% of intubated patients (fisher’s exact test = 0.000). in 1.2% of patients with lma cough was recorded; it was also seen in 7% of the intubated patients (fisher’s exact...
