BACKGROUND: Exercise-induced external iliac artery endofibrosis (EIAE) is rare and has been described primarily in endurance male cyclists. Clinically, it presents as claudication during maximal exercise with quick resolution after exercise. Most patients have fibrotic changes within the external iliac artery (EIA). We describe our experience with EIAE and propose ...

The beneficial effect of exercise on hippocampal plasticity is possibly mediated by increased angiogenesis and neurogenesis. In angiogenesis insulin-like growth factor-1 (IGF-1), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor 1, alpha subunit (HIF1α) are important factors, while the induction of neurogenesis requires signaling through the VEGF receptor, Flk-1 (VEGFR-2). ...

Patients with chronic obstructive pulmonary disease (COPD) are progressively limited in their ability to undertake normal everyday activities by a combination of exertional dyspnoea and peripheral muscle weakness. COPD is characterised by expiratory flow limitation, resulting in air trapping and lung hyperinflation. Hyperinflation increases acutely under conditions such as exercise ...
