Embedded systems often use a heterogeneous multi-core processor to improve performance and energy efficiency. This multi-core processor is composed of a general purpose processor (GPP), which manages the program flow and I/O, and a digital signal processor (DSP), which processes mass data. An inter-processor communication (IPC) mechanism is thus required to exchange data between a GPP and a DSP...

UNLABELLED Ischemic preconditioning (IPC) is a robust neuroprotective phenomenon whereby brief ischemic exposure confers tolerance to a subsequent ischemic challenge. IPC has not been studied selectively in CNS white matter (WM), although stroke frequently involves WM. We determined whether IPC is present in WM and, if so, its mechanism. We delivered a brief in vivo preconditioning ischemic ins...

The Reperfusion Injury Salvage Kinase (RISK) pathway is considered the main pro-survival kinase cascade mediating the ischaemic preconditioning (IPC) cardioprotective effect. To assess the role of PI3K-Akt, its negative regulator PTEN and other pro-survival proteins such as ERK and STAT3 in the context of IPC, C57BL/6 mouse hearts were retrogradely perfused in a Langendorff system and subjected...

Reperfusion is mandatory after ischemia but also triggers ischemia-reperfusion (I/R) injury. Ischemic preconditioning (IPC) can limit endothelial I/R injury. Nonetheless, translation of IPC to the clinical arena is often disappointing. Since application of IPC typically relates to older patients, efficacy of IPC may be attenuated with aging. Our objective was to examine the impact of advanced a...

OBJECTIVES It has been shown that sarcolemmal rupture can occur during reenergization in cardiomyocytes in which previous ischemia has induced sarcolemmal fragility by calpain-dependent hydrolysis of structural proteins. We tested the hypothesis that attenuated calpain activation contributes to the protection against reperfusion-induced cell death afforded by ischemic preconditioning (IPC), and...

PURPOSE Repeated bouts of ischemia followed by reperfusion (i.e., ischemic preconditioning (IPC)) protect against damage after a myocardial infarction. Recent observational data indicate that IPC improves exercise performance. However, no previous study has examined potential underlying mechanisms for this effect of IPC. Therefore, we examined the potential of IPC to improve 5-km running time t...

Ischemic preconditioning (IPC) induces distinctive changes in mitochondrial bioenergetics during warm (37 degrees C) ischemia and improves function and tissue viability on reperfusion. We examined whether IPC before 2 h of hypothermic (27 degrees C) ischemia affords additive cardioprotection and improves mitochondrial redox balance assessed by mitochondrial NADH and flavin adenine dinucleotide ...

The cholinergic division of the avian nucleus isthmi, the homolog of the mammalian nucleus parabigeminalis, is composed of the pars parvocellularis (Ipc) and pars semilunaris (SLu). Ipc and SLu were studied with in vivo and in vitro tracing and intracellular filling methods. 1) Both nuclei have reciprocal homotopic connections with the ipsilateral optic tectum. The SLu connection is more diffus...

Prior to the 2014-2015 Ebola outbreak, infection prevention and control (IPC) activities in Liberian healthcare facilities were basic. There was no national IPC guidance, nor dedicated staff at any level of government or healthcare facility (HCF) to ensure the implementation of best practices. Efforts to improve IPC early in the outbreak were ad hoc and messaging was inconsistent. In September ...

Three studies are presented that demonstrate the psychometric properties and initial validation of the International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC). The IPIP-IPC is a brief 32-item assessment of the interpersonal cirucmplex designed to be used when time is limited or when participants have difficulty understanding the adjective items used in more traditional assessmen...
