Left ventricular hypertrophy leads to heart failure and represents a high risk leading to premature death. Cyclic nucleotides (cAMP and cGMP) play a major role in heart contractility and cyclic nucleotide phosphodiesterases (PDEs) are involved in different stages of advanced cardiac diseases. We have investigated their contributions in the very initial(More)
BACKGROUND Alterations in muscarinic receptor expression and acetylcholinesterase (AchE) activity have been observed in tissues from Sudden Infant Death Syndrome (SIDS). Vagal overactivity has been proposed as a possible cause of SIDS as well as of vasovagal syncopes. The aim of the present study was to seek whether muscarinic receptor overexpression may be(More)
OBJECTIVE Heart failure with preserved left-ventricular ejection fraction (HF-PEF) is an entity leading to pulmonary congestion because of impaired diastolic filling. This syndrome usually strikes those who have experienced a long history of hypertension or metabolic risk factors. Pathophysiological mechanisms are not fully understood, and standard therapy(More)
BACKGROUND Sudden infant death syndrome (SIDS) remains the leading cause of death among infants less than 1 year of age. Disturbed expression of some neurotransmitters and their receptors has been shown in the central nervous system of SIDS victims but no biological abnormality of the peripheral vago-cardiac system has been demonstrated to date. The present(More)
OBJECTIVE Left-ventricular hypertrophy and interstitial fibrosis are the main pathophysiological factors of heart failure with preserved ejection fraction. Blockade of the serotonin 5-HT2B receptor (5-HT2BR) has been shown to reduce cardiac hypertrophy, oxidative stress, and extracellular cell matrix activation. In this study, we evaluated the effects of(More)
AIMS Conductive disorders following open-heart valvular surgery represent serious complications that may require definitive pacemaker implantation. The natural history of these troubles is not well established thus, controversy persist concerning the timing of pacemaker implantation. In this study we identify the predictive factors of permanent conductive(More)
Acute renal failure following hunger strike has been rarely reported. We report a 47-year-old man, prisoner, who developed an acute renal failure secondary to hypovolemia and major rhabdomyolysis. Failure of hydration with persistence of oliguria and secondary pulmonary edema required hemodialysis with eventually a favorable outcome.
