This study was conducted in order to evaluate the effects of long term ageing on toughness and resilient modulus of asphalt concrete mixtures containing Electric Arc and Basic Oxygen Furnace steel slags. After initial evaluation of the properties of steel slags using X-ray Diffraction and Scanning Electric Microscope, eleven sets of laboratory mixtures were prepared. Each set was treated replac...

BACKGROUND Preoperative anaemia and low exertional oxygen uptake are both associated with greater postoperative morbidity and mortality. This study reports the association among haemoglobin concentration ([Hb]), peak oxygen uptake (V˙O2 peak) and anaerobic threshold (AT) in elective surgical patients. METHODS Between 1999 and 2011, preoperative [Hb] and cardiopulmonary exercise tests were rec...

PURPOSE To examine the effect of aerobic training in mitigating trastuzumab-mediated left ventricular (LV) remodeling in women with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. EXPERIMENTAL DESIGN Seventeen women (53 +/- 7 years) with HER2-positive breast cancer did aerobic training during the first 4 months of adjuvant trastuzumab. Peak oxygen consumption and magne...

Abstract Introduction Cardiorespiratory fitness, measured as peak oxygen uptake (VO2peak), is a strong predictor of cardiovascular disease (CVD) morbidity and mortality estimated to have large genetic component (∼60%). However, the determinants are yet be established. Our research group recently identified novel variants associated with directly VO2peak. Interestingly, most were specific female...

The purpose of this study was to investigate whether helium-hyperoxia (HeHOx) would allow greater tolerance to maximal and submaximal exercise compared to hyperoxia (HOx) on isolation in hypoxaemic chronic obstructive pulmonary disease (COPD) patients under long-term oxygen therapy. In a double-blind study, 24 males in the Global Initiative for Chronic Obstructive Lung Disease functional class ...

Uncontrolled studies have suggested that the newer oral phosphodiesterase inhibitors milrinone and enoximone acutely improve exercise performance in patients with severe chronic cardiac failure. To determine whether an oral placebo presented as an inotropic agent could acutely enhance exercise capacity, two separate groups of stable heart failure patients were studied by serial exercise testing...
