The hyperemic response in exercising skeletal muscle is dependent on muscle fiber-type composition and fiber recruitment patterns, but the vascular control mechanisms producing exercise hyperemia in skeletal muscle remain poorly understood. The purpose of this study was to test the hypothesis that arterioles from white, low-oxidative skeletal muscle are less responsive to adenosine-induced dila...
The regulatory factor Differentiation Inhibiting Activity/Leukaemia Inhibitory Factor (DIA/LIF) suppresses the differentiation of cultured embryonic stem (ES) cells. In the present study, it is shown that ES cell lines can be derived and maintained in the absence of feeder layers using medium supplemented with purified DIA/LIF. These cells can differentiate normally in vitro and in vivo and the...
88 Despite the advances in the treatment of patients with coronary artery disease, sudden cardiac death is still unacceptably prevalent. Patients with ischemic heart disease usually require a combination of therapies (drugs and coronary intervention) and may continue to experience symptoms. Recently, numerous percutaneous interventional treatments and diagnostic tools have been developed to dia...
OBJECTIVES The effects of operational modes of intra-aortic balloon pumping (IABP) on coronary haemodynamics and oxygen delivery/demand ratio are unknown and were investigated in an experimental model of myocardial ischaemia reperfusion. METHODS Healthy swine (n = 24) underwent 120-minute ligation of the left anterior descending coronary artery followed by 24 h of reperfusion and were randoml...
We describe a randomized incremental algorithm for computing the Delaunay triangulation of a set of points and a recent technique of applying it to terrain generation. The algorithm is optimal, using a Directed Acyclic Graph (DAG)-based location structure for the incremental insertion which achieves an expected running time of O(n log n) and O(n) expected storage. The analysis of the expected s...
INTRODUCTION Data is sparse on drug-induced anaphylaxis (DIA) and there have not been studies assessing the differences in clinical characteristics and management of DIA between adults and children. OBJECTIVE We assessed the percentage, diagnosis, and management of DIA among all anaphylaxis visits in three pediatric and one adult emergency departments (ED) across Canada. METHODS Children pr...
