Although the benefits of regular exercise in controlling cardiovascular risk factors have been extensively proven, little is known about the long-term cardiovascular effects of regular and extreme endurance sport practice, such as jogging, cycling, rowing, swimming, etc. Recent data from a small series suggest a relationship between regular, long-term endurance sport practice and atrial fibrill...

BACKGROUND Landiolol hydrochloride is a new β-adrenergic blocker with a pharmacological profile that suggests it can be administered safely to patients who have sinus tachycardia or tachyarrhythmia and who require heart rate reduction. This study aimed to investigate whether intraoperative administration of landiolol could reduce the incidence of atrial fibrillation (AF) after cardiac surgery. ...

BACKGROUND The major cat allergen Fel d I consists of two polypeptide chains linked by disulfide bonds, each of which has been expressed in bacteria. To investigate the antigenic structure of Fel d I, antibody binding to the native molecule and to each recombinant chain were compared. METHODS Polyclonal human IgE and IgG antibodies and monoclonal antibodies (mAbs) to Fel d I were compared for...

Ablation has become a cornerstone of therapy for atrial fibrillation (AF), the most common arrhythmia in the Western world and an important cause of morbidity and mortality.1 However, the optimal approach for ablation remains hotly debated, and this is particularly true for the selection of procedural endpoints. Since seminal studies by Haïssaguerre et al.2 showed that ectopy from the pulmonary...

This paper proposes a framework for the integration of the algebra of communicating processes (ACP) and the algebra of ownomials (AF). Basically, this means to combine axiomatisations of parallel and looping operators. To this end a model of process graphs with multiple entries and exits is introduced. In this model the usual operations of both algebras are de ned, e.g. alternative composition,...
