Bough et al. have recently demonstrated anticonvulsant effects of the 'classic' ketogenic diet (KD) in the pentylenetetrazol infusion model in rats. Proconvulsant effects were seen, however, when the 'classic' diet was tested against maximal electroshock (MES) seizures. These differing results may reflect the fact that the two models involve different kinds(More)
Male Wistar rat pups were weaned at 20 days of age and placed on either a control diet or a ketogenic diet containing medium-chain triglyceride (MCT) oil. After 10 days on the diets, they were subjected to one of four seizure tests-maximal electric shock, threshold electroconvulsive shock, threshold pentylenetetrazol, or maximal pentylenetetrazol. After(More)
Recent studies have shown neuroprotective effects of acetylsalicylic acid (ASA) in cell cultures and hippocampal slices. The present study demonstrates similar effects in a whole-animal modal of focal ischemic stroke. Focal cortical ischemia was produced in Wistar rats by ligation of the common carotid and middle cerebral arteries. Subjects were sacrificed(More)
This article describes an MR-safe treadmill that enables cardiovascular exercise stress testing adjacent to the MRI system, facilitating cardiac MR imaging immediately following exercise stress. The treadmill was constructed of nonferromagnetic components utilizing a hydraulic power system. Computer control ensured precise execution of the standard Bruce(More)
OBJECTIVE To determine whether phlebotomy contributes to changes in hemoglobin and hematocrit levels in hospitalized general internal medicine patients. DESIGN Retrospective cohort study. SETTING General internal medicine inpatient service at a tertiary care hospital. PARTICIPANTS All adult patients discharged from the Toronto General Hospital's(More)
D uring the past 30 years, there has been a significant decrease in cancer mortality rates, predominantly attributable to improvements in treatment options. 1 However, survivors are at increased risk of premature cardiac disease, 2 both because of the overlap in risk factors for cancer and cardiovas-cular disease 3 and the cardiotoxic effects of cancer(More)
Truncus arteriosus (TA) is a rare congenital condition defined as a single arterial vessel arising from the heart that gives origin to the systemic, pulmonary and coronary circulations. We discuss the unique case of a 28 year-old female patient with unrepaired TA and interruption of the aortic arch who underwent cardiovascular magnetic resonance (CMR).
CONTEXT Many patients have palpitations and seek advice from general practitioners. Differentiating benign causes from those resulting from clinically significant cardiac arrhythmia can be challenging and the clinical examination may aid in this process. OBJECTIVE To systematically review the accuracy of historical features, physical examination, and(More)
BACKGROUND Stress cardiac magnetic resonance (CMR) has typically involved pharmacologic agents. Treadmill CMR has shown utility in single-center studies but has not undergone multicenter evaluation. METHODS AND RESULTS Patients referred for treadmill stress nuclear imaging (SPECT) were prospectively enrolled across 4 centers. After rest (99m)Tc SPECT,(More)
