BACKGROUND Adrenomedullin (AM) is a potent vasodilator peptide. Plasma AM levels are increased in heart diseases and in sepsis. Heart surgery under cardiopulmonary bypass (CPB) induces a systemic inflammatory response. METHODS We measured plasma AM, cAMP (the second messenger of AM), C-reactive protein (CRP) and haemodynamic parameters in 29 patients(More)
The prevalence of stroke is increased in diabetic patients. The vasoconstrictor peptide endothelin-1 (ET-1) has been implicated in the development of cerebral vasospasm after stroke but its role in the physiological regulation of cerebral blood flow (CBF) is not well known. Our aim was to assess the relationship between CBF and plasma ET-1 levels in type I(More)
In this paper, a comparison between the Field-Oriented Control (FOC) scheme and the Generalized Proportional Integral (GPI) controller for a permanent magnet synchronous motor (PMSM) is presented. The GPI controller scheme consists in two stages, the first one is a speed control loop which gives the reference control signals, the second stage is a current(More)
We report the occurrence of a bilateral pneumothoraces after unilateral central venous catheterization of the right subclavian vein in a 70-year-old patient. The patient had no history of pulmonary or pleural disease and no history of cardiothoracic surgery. Two days earlier, she had a median laparotomy under general and epidural anaesthesia.
