BACKGROUND The epithelial reticular basement membrane (Rbm) of the airway wall thickens in patients with asthma. However, whether the thickening parallels whole airway wall thickening, which limits airflow, is unknown. The aim of this study was to examine the correlation between the bronchial Rbm thickening and whole airway wall thickening in asthma. In addition, the association of Rbm and whol...

Metal spinning as a kind of manufacturing process has capability to shape hollow components. In present work shear spinning process is used to formplates into conical shapes. Moreover, the aim of this research is to demonstrate the impact of the process parameters (i.e. feeding rate and spindle speed) on wall thickness. This approachwas done by experimental and finite elements method. The resul...

BACKGROUND To use cardiovascular magnetic resonance to investigate left ventricular wall thickness and the presence of asymmetrical hypertrophy in young army recruits before and after a period of intense exercise training. METHODS AND RESULTS Using cardiovascular magnetic resonance, the left ventricular wall thickness was measured in all 17 segments and a normal range was calculated for each....

generaly pressure vessels should withstand internal and external pressures in the form of static or periodic stresses. if the application of such a vessel requires the lowest possible weight, the fracture mechanics approach may be considened in design procedure in order to obtain the minimum wall thickness. in this work the thickness of the vessel wall was determined using k values and smallest...

BACKGROUND The intestinal wall can be visualized using high resolution transabdominal ultrasound (TUS). TTUS measurement of the bowel wall thickness has been described in adults but data are lacking in children. The purpose of this prospective study was to sonographically investigate bowel wall thickness in healthy children and children with Crohn's disease. MATERIAL AND METHODS TUS (5-15 MHz...

The effect of acute alterations in coronary blood flow (CBF) on left ventricular (LV) end-diastolic wall thickness was measured by reflected ultrasound in twelve anesthetized dogs. During five minutes of coronary ligation, wall thickness decreased from a control of 9.0 +/- 0.3 mm to 8.1 +/- 0.3 mm (P less than 0.001); during reperfusion (reactive hyperemia), wall thickness was greater than cont...

PURPOSE We aimed to visualize the retinal arterial wall thickness, assisted by noninvasive adaptive optics scanning laser ophthalmoscopy (AO-SLO). METHODS The arterial wall thickness was measured and compared between one normal subject and one patient suffering from malignant hypertensive retinopathy. RESULTS Increased arterial wall thickness was revealed with a newly developed AO-SLO syste...

BACKGROUND Risk prediction of rupture of intracranial aneurysms is poor and is based mainly on lumen characteristics. However, characteristics of the aneurysm wall may be more informative predictors. The limited resolution of currently available imaging techniques and the thin aneurysm wall make imaging of wall thickness challenging. OBJECTIVE To introduce a novel protocol for imaging wall th...
