BACKGROUND Airway remodeling in asthma and COPD results in bronchial wall thickening. The thickness of the bronchial wall can be measured in high-resolution computed tomography. The objectives of the study were to assess the bronchial lumen and wall dimensions in asthma and COPD patients, in relation to disease severity, and to compare the airway dimensions in patients with asthma and COPD. M...

OBJECTIVE To evaluate fetal myocardial movement by using newly developed ultrasonic technique. METHODS We analyzed 50 normal fetuses between 25 and 41 weeks' gestation for changes in thickness of fetal myocardium using the phased-tracking method, a technique with high vertical distance resolution and the potential to evaluate fine ventricular wall movements. We analyzed differences in the rat...

iran is believed to occupy the second place, following turkey, among the apricot producing countries in the world. iran is faced with problems in export of apricot due to little or non-observance of drying principals and inattention to world market requirements. the physical and mechanical properties of agricultural products are the most needed and important parameters for design and developmen...

Conjugate natural convection-conduction heat transfer in a square enclosure with a finite wall thickness is studied numerically in the present paper. The governing parameters considered are the Rayleigh number (5 × 10(3) ≤ Ra ≤ 10(6)), the wall-to-fluid thermal conductivity ratio (0.5 ≤ Kr ≤ 10), and the ratio of wall thickness to its height (0.2 ≤ D ≤ 0.4). The staggered grid arrangement toget...

Methods All patients with confirmed AFD who had cardiac MRI at our center were included. Short-axis steady state free precession cines and segmented inversion recovery late gadolinium enhancement (LGE) images were acquired using standard parameters. Offline analysis was performed for LV volumes and maximum end-diastolic wall thickness (EDWTmax). Patients were categorized into 4 groups: 1) no wa...
