Background: Sarcocystosis in South American camelids (SAC) is an important parasitic disease which results in economical loss due to carcass condemnation. Meat products from camelids are significant source of animal protein in several American countries. Sarcocystis spp. producing macroscopical cysts in these animals have been nominated as S. aucheniae, S. tilopodi, and S. guanicoecanis. The ai...

BACKGROUND Wall motion score at dobutamine stress echocardiography is an independent predictor of mortality. We sought to determine whether quantification of DSE by strain rate imaging was incremental to wall motion score for predicting outcome. METHODS AND RESULTS In 646 patients undergoing dobutamine stress echocardiography for the evaluation of known or suspected coronary disease, customiz...

The relations between end-diastolic (D) and end-systolic (S) fiber angles (a) and sarcomere lengths (s) have been previously studied at different sites in canine left ventricular myocardium. However, no postulates have been advanced for predicting a and s in successive states of the ejection cycle (D or S) or at different sites in one state when the semimajor (Z) and semiminor (R) axes of the w...

background: emergence of antimicrobial resistance toward a number of conventional antibiotics has triggered the search for antimicrobial agents from a variety of sources including the marine environment. objectives: the aim of this study was to evaluate the antimicrobial potential of holothuria leucospilota from qeshm and kharg islands against some selected bacteria and fungi. materials and met...

Consider a steady Stokes flow bounded by a flat wall to which a separatrix, not tangent to the wall, is attached at point S. If the wall is made to slowly oscillate periodically with small amplitude in a longitudinal direction, then the Poincare map associated with this perturbed flow has a fixed point on the wall near S with an invariant manifold. This result also holds for flows bounded by a ...
