Thyroid hormone coordinates respiratory control maturation and adenine nucleotide translocator expression in heart in vivo.

abstract：BACKGROUND:Mitral regurgitation (MR) represents the principal indication for reoperation in patients after repair of atrioventricular septal defects (AVSD). Reports of mitral valvuloplasty (MVP) in such patients are few; the alternative, mitral valve replacement (MVR), necessitates commitment to future valve replacemen...
