Recent advances in interprocess communication (IPC) performance have been exclusively based on threadmigrating IPC designs. Thread-migrating designs assume that IPC interactions are synchronous, and that user-level execution will usually resume with the invoked process (modulo preemption). This IPC design approach offers shorter instruction path lengths, requires fewer locks, has smaller instru...
Zheng, Jingang, Andrew Chin, Inga Duignan, Kyung-Heon Won, Mun K. Hong, and Jay M. Edelberg. Growth factor-mediated reversal of senescent dysfunction of ischemia-induced cardioprotection. Am J Physiol Heart Circ Physiol 290: H525–H530, 2006. First published September 23, 2005; doi:10.1152/ajpheart.00470.2005.— Based on the role of tumor necrosis factor(TNF) in ischemic preconditioning (IPC) and...
Extracellular ATP plays an important role in ischemic preconditioning (IPC) through the activation of P(2y) purinoceptors. This study examined whether ATP-stimulated P(2y) purinoceptors are coupled to pertussis toxin (PTX)-insensitive G protein and whether activation of this pathway enhances myocardial protection afforded by IPC. The rat was treated with PTX for 48 h, and the heart was then iso...
Interprocess communication (IPC) provides the fundamental mechanism for the Mach microkernel to be extensible and exible. Mach IPC provides eecient communication mechanisms for many applications. However, it does not provide suucient functionality for real-time applications which have rigid timing constraints among threads. In Real-Time Mach (RT-Mach), we have extended Mach IPC to be priority i...
Ischemic preconditioning (IPC) strongly protects against ischemia-reperfusion injury; however, its effect on subsequent myocardial oxygenation is unknown. Therefore, we determine in an in vivo mouse model of regional ischemia and reperfusion (I/R) if IPC attenuates postischemic myocardial hyperoxygenation and decreases formation of reactive oxygen/nitrogen species (ROS/RNS), with preservation o...
BACKGROUND It is well established that acute ischemic preconditioning (IPC) protects against ischemia-reperfusion (IR) injury; however, the effectiveness of repeated IPC exposure has not been extensively investigated. We aimed to determine whether daily IPC episodes provide continued protection from IR injury in a human forearm model, and the role of cyclooxygenase-2 in these responses. METHO...
Introduction: Using brief episodes of ischemia and reperfusion (IR) prior to a more sustained IR insult – ischemic preconditioning (IPC) – can reduce IR injury of the heart, brain and many other tissues. The purpose of present study was to investigate the effect of 2min ischemic periods on subsequent rat renal IR injury. Methods: Male rat's renal IR injury was investigated in a right nephrectom...
INTRODUCTION An important component of treatment failure in gastric cancer (GC) is cancer dissemination within the peritoneal cavity and nodal metastasis. Intraperitoneal chemotherapy (IPC) is considered to give a fundamental contribute in treating advanced GC. The purpose of the study is to investigate the effects of IPC in patients with advanced GC. MATERIAL AND METHODS A systematic review ...
conclusions pretreatment with epo and application of ipc significantly ameliorated the renal injury induced by bilateral renal ir. however, both treatments attenuated renal dysfunction and oxidative stress in kidney tissues. there were no significant differences between pretreatment with epo or application of ipc. materials and methods twenty four male wistar rats were allocated into four exper...
AIMS Ischaemic preconditioning (IPC) is an adaptive mechanism that renders the myocardium resistant to injury from subsequent hypoxia. Although reactive oxygen species (ROS) contribute to both the early and late phases of IPC, their enzymatic source and associated signalling events have not yet been understood completely. Our objective was to investigate the role of the Nox1 NADPH oxidase in ca...
