background: antioxidants such as α-tocopherol (vitamin e) and β-carotene (vitamin a) play an important role in protective effect of repeated brief periods of ischemia, namely ischemic preconditioning (ipc). values of these antioxidants were investigated and compared after induction of ischemia reperfusion (ir) and kidney ipc in both male and female rats. methods: forty eight wistar rats were di...

Avian intrapulmonary chemoreceptors (IPC) are vagal respiratory afferents that are inhibited by high lung Pco(2) and excited by low lung Pco(2). Previous work suggests that increased CO(2) inhibits IPC by acidifying intracellular pH (pH(i)) and that pH(i) is determined by a kinetic balance between the rate of intracellular carbonic anhydrase-catalyzed CO(2) hydration/dehydration and transmembra...

Conflicting evidence exists whether diabetic myocardium can be protected by ischemic preconditioning (IPC). The phosphatidylinositol 3-kinase (PI3K)-Akt pathway is important in IPC. However, components of this cascade have been found to be defective in diabetes. We hypothesize that IPC in diabetic hearts depends on intact signaling through the PI3K-Akt pathway to reduce myocardial injury. Isola...

BACKGROUND Adenosine-enhanced ischemic preconditioning (APC) extends the protection afforded by ischemic preconditioning (IPC) by both significantly decreasing infarct size and significantly enhancing post-ischemic functional recovery. In this study, the anti-infarct effects and the anti-stunning effects of APC in contributing to enhanced post-ischemic functional recovery were determined and co...

An interprocess communication (IPC) mechanism has been developed that enables lowlatency communication of structured data. This is becoming more important for such applications as distributed query processing of object-oriented databases (OODB) and hyper-text world-wide web (WWW) pages. In these applications, a sender typically creates structured data and sends them to a receiver. The main obst...

Nitric oxide (NO) and protein S-nitrosylation (SNO) have been shown to play important roles in ischaemic preconditioning (IPC)-induced acute cardioprotection. The majority of proteins that show increased SNO following IPC are localized to the mitochondria, and our recent studies suggest that caveolae transduce acute NO/SNO cardioprotective signalling in IPC hearts. Due to the close association ...

This paper describes object-oriented (OO) techniques for encapsulating OS interprocess communication (IPC) mechanisms with C++ wrappers. The paper focuses on the C++ wrappers provided by the IPC SAP components in the ACE framework [2]. ACE is a collection of reusable C++ class libraries and OO framework components that simplify the development of portable, high-performance and real-time communi...

The hippocampal CA1 region is sensitive to hypoxic and ischemic injury but can be protected by ischemic preconditioning (IPC). However, the mechanism through which IPC protects hippocampal CA1 neurons is still under investigation. Additionally, the role of autophagy in determining the fate of hippocampal neurons is unclear. Here, we examined whether IPC induced autophagy to alleviate hippocampa...

The IPC chronic classification development process started with the preparation of the IPC Manual version 2.0. Since the main focus of IPC has been on classification of acute food insecurity, refining tools for the acute analysis was also the main priority in the new version of the Manual. Draft tools for analyzing chronic food insecurity were included in the Annex of the Manual, and IPC users ...
