We investigated the feeding habits of the teiid lizard Cnemidophorus littoralis in the markedly seasonal habitat of Restinga da Barra de Maricá (22 degrees 57'S, 43 degrees 50'W), Rio de Janeiro State, Brazil, to evaluate to what extent its diet is ontogenetically, sexually, and/or seasonally conservative. Lizard stomach contents were analyzed, identified,(More)
BACKGROUND While some studies indicate that permanent pacemaker implantation is associated with development of tricuspid regurgitation (TR), other studies indicate no association.Little is known about the impact of temporary lead insertion during ablation procedures, or whether therapy (CRT) prevents TR post-device implantation. HYPOTHESIS We hypothesized(More)
Given the increasing numbers of cardiac device implantations worldwide, it is important to determine whether permanent endocardial leads across the tricuspid valve can promote tricuspid regurgitation (TR). Virtually all current data is retrospective, and indicates a signal of TR being increased after permanent lead implantation. However, the precise(More)
