A problem arises in cases of CAO in patients who have not been active smokers. In these cases, following the definition of COPD, other factors such as passive smoking or exposure to other inhaled irritants play a major role. Indeed, a number of previous studies have established passive smoking or biomass exposure as causes of CAO and therefore COPD [7, 8] . In those cases when the patient has n...

Myocardium undergoes functional changes in the infarcted region primarily due to ischemia. Following myocyte functional alterations of the noninfarcted myocardium are caused by remodelling and hypertrophy. We have monitored and compared changes in the electrocardiographical (ECG) image after coronary artery occlusion (CAO, n=5) and intracoronary endothelin-1 (ET-1, n=3) administration during a ...

The effect of CaO on the formation of β- and γ-zirconia nanoparticles from α-zirconia was investigated and their stability evaluated via mechanical activation. α-ZrO2+8.5wt%CaO powder was milled for 2-150 hours with ball-to-powder weight ratios (BPWR) of 40:1 and 60:1. Structural evaluations were conducted using X-Ray diffraction and scanning electron microscope (SEM). Thermal analysis wa...

BACKGROUND A biphasic-plateau pattern in the maximal expiratory flow-volume (MEFV) curve has been described after single-lung transplantation (SLT) in patients with chronic airways obstruction (CAO). It has been theorized that this pattern is either related to stenosis at the anastomotic or subanastomotic site, or the sum of the airflow contribution from the native lung with airways obstruction...

INTRODUCTION Central airway obstruction (CAO) refers to obstruction involving the trachea, mainstem, or lobar bronchi. These lesions can be either benign or malignant. Obstruction of these areas may lead to dyspnea, atelectasis, post-obstructive pneumonia, and death. Treatment options to relieve CAO include airway dilation, laser techniques, cryotherapy, and stenting. CAO is becoming more preva...

Quantitative analysis of CaO in limestone mining is mandatory, not only for ore exploration, but also for grade control. A partial least squares regression (PLSR) CaO estimation technique was developed for limestone mining. The proposed near-infrared spectroscopy (NIR)-based method uses reflectance spectra of the rock sample surface in the visible to short-wave infrared wavelength regions (350–...

Fe2O3 nanorods exposing (001) and (010) plane as well as Fe2O3 nanosheets exposing (001) plane have been successfully synthesized. Fe2O3 nanosheets exhibit better cycle performance and rate capabilities than that of Fe2O3 nanorods. The discharge capacity of Fe2O3 nanosheets can stabilize at 865 mAh/g at the rate of 0.2 C (1C = 1000 mA/g) and 570 mAh/g at the rate of 1.2 C after 80 cycles, which...
