BACKGROUND A study was undertaken to determine if quantitative CT estimates of lung parenchymal overinflation and airway dimensions in smokers with a normal forced expiratory volume in 1 s (FEV(1)) can predict the rapid decline in FEV(1) that leads to chronic obstructive pulmonary disease (COPD). METHODS Study participants (n = 143; age 45-72 years; 54%(More)
The aim of the current study was to use computed tomography (CT) to estimate airway wall and lumen, and arterial and parenchyma dimensions in children throughout the growth period, and to provide normative data to study alterations caused by pulmonary disease. Clinical CT scans reported as normal that were performed in children for nonpulmonary and(More)
The main focus of this paper is to design a voltage controlled oscillator (VCO) with the oscillation frequency of 2. 4 GHz. A completely integrated LC-VCO, compatible with the ISM band is designed using 180 nm CMOS technology and with supply voltage of 1. 8 V. The inductor-capacitor (LC) tank uses varactors as tuning elements. The n-type(More)
BACKGROUND AND PURPOSE A novel method to quantify carotid artery stenosis by using the continuity principle was evaluated. It was hypothesized that the novel method improved the accuracy of carotid ultrasound in assessing carotid artery stenosis. METHODS Forty-nine patients were retrospectively studied. They were at a high risk for stroke and myocardial(More)
BACKGROUND Decompensated liver disease due to portal hypertension leads to significant morbidity and mortality. Statins can modulate intrahepatic vascular tone, but the clinical significance remains uncertain. AIM To determine the effects of statin use on the risk of liver decompensation and death among patients with chronic viral hepatitis. METHODS We(More)
