“Ictal asystole is being recognized as a potential mechanism of sudden unexplained death

in epilepsy (SUDEP). We report a case of a patient without known cardiac disease presenting with ictal asystole resulting in syncope, trauma, and need for pacemaker implantation. The management of ictal asystole is also briefly reviewed. This case is notable for the asystolic episode wholly captured on video-electroencephalogram/electrocardiogram, the serious risk of trauma and death posed to the patient, and its implications for the mechanism of ictal asystole. This report will alert physicians to the possibility of ictal arrhythmias as a cause of syncope and SUDEP in vulnerable patients. QNZ inhibitor (PACE 2011; 14)”
“Conservation management actions and decisions are often defined by the location of ecological boundaries, for example, the present range of invasive or threatened species. The position of these boundaries can be cryptic, and managers must therefore directly Nutlin-3 price sample sites, an expensive and time-consuming process. While accurate boundary location techniques have been considered by ecological theorists, the issue of cost-effective, or optimal

boundary location has not. We propose a general framework for boundary location which incorporates both cost-efficiency and uncertainty. To illustrate its application, we use it to help locate an infectious disease front in the endangered Tasmanian devil population. The method ensures optimal spatial sampling by maximizing the expected information gained from each sample. When resources are limited, our method provides more accurate estimates of the boundary location than traditional sampling protocols. Using a formal decision

theory sampling design encourages economically efficient actions, and provides defensible and transparent rationale for management ABT-263 manufacturer actions. Crown Copyright (C) 2009 Published by Elsevier Ltd. All rights reserved.”
“Correlations among physical and electrical properties of atomic layer deposited (ALD)-Al2O3 on H2O-prepulsed Ge(100) have been investigated to evaluate Al2O3 as an ultrathin interface passivation layer for higher-k/Al2O3/Ge gate stacks. In situ XPS in the ALD environment provides insights into the local composition evolution during the initial stages of ALD, evidencing (a) an incubation regime that may limit the minimum achievable capacitance equivalent thickness (CET) of these gate stacks, and (b) residual hydroxyl incorporation in the film consistent with the observed dielectric constant similar to 7.2. Thickness scaling of the CET is consistent with a nearly abrupt interface as measured by synchrotron radiation photoemission spectroscopy (SRPES). SRPES studies also reveal that forming gas anneal provides passivation through monolayer-level formation of stoichiometric GeO2, suggesting a complex chemical interaction involving residual -OH groups in the as-grown ALD-Al2O3.
