BACKGROUND Capsule endoscopy (CE) is a valuable tool in the diagnostic evaluation of obscure gastrointestinal bleeding, but limited information is available on the reproducibility of CE findings. OBJECTIVE To compare two successive CE studies with push enteroscopy (PE) in patients presenting with chronic obscure gastrointestinal bleeding. METHODS A(More)
BACKGROUND/AIMS Experimental and clinical studies have shown the direct toxic effects of cigarette smoke (CS) on the myocardium, independent of vascular effects. However, the underlying mechanisms are not well known. METHODS Wistar rats were allocated to control (C) and cigarette smoke (CS) groups. CS rats were exposed to cigarette smoke for 2 months. (More)
Genetic algorithms (GA) mimic natural reproduction to search for complex problem solutions. Their principles are shortly explained. A point of interest is the regular and repetititve structure of computation involving communication, data exchanges, and control phases. Interaction with presentation and analysis tools is also a requirement. This make sense(More)
Anemia is a prevalent comorbidity and marker of a poorer prognosis in patients with heart failure (HF). Its clinical relevance, as well as its pathophysiology and the clinical management of these patients are important subjects in the specialized literature. In the present review, we describe the current concepts on the pathophysiology of anemia in HF, its(More)
