Three of thirteen Oryzomys acritus, Emmons and Patton 2005 (Rodentia: Muridae: Sigmodontinae) 3 17 nitidus, Thomas 1884, collected from Noël Kempff National Park, Bolivia, 2002 to 2005, tested positive for Leishmania (Leishmania) amazonensis or L. (L.) mexicana negative (Viannia) spp. using the polymerase chain reaction (PCR). Based on previous records in humans, rodents, sand flies geographic distributions mexicana, it was concluded that were infected with amazonensis. These results...

Summary Isolated noncompaction of ventricular myocardium is a rare cardiomyopathy with persistence myocardial architecture such as seen early in fetal development numerous prominent trabeculations and deep intertrabecular spaces. Symptoms are related to cardiac failure, arterial embolism, severe arrhythmias. Familial recurrence has been described. We describe case where isolated could be recognized on an ultrasound study at 23 weeks gestation, thus supporting the developmental hypothesis.

Abstract Introduction Global longitudinal strain is recommended by the European Society of Cardiology to detect subclinical left ventricular (LV) dysfunction, but markedly load-dependent. Myocardial work was recently introduced as a clinical tool study LV function pressure-strain analysis. Since myocardial incorporates afterload, it assumed be less afterload-dependent than strain, relationship with afterload incompletely understood. Hypothesis better measure during elevated afterload....
