PURPOSE To determine whether ischemic preconditioning (IPC) upregulates certain retinal survival factors and to assess the protective effect of retinal IPC against light-induced photoreceptor degeneration. METHODS Albino rats underwent IPC induced by raising the intraocular pressure in one eye to 120 mm Hg for 5 minutes. The fellow eye underwent sham treatment. Basic fibroblast growth factor ...

Recent studies demonstrated that brief period of Ca2+ depletion and repletion (Ca2+ preconditioning, CPC) has strong protective effects against ischemia in a rat heart. CPC and classic preconditioning (IPC) were compared in relation with infarct size and protein kinase C (PKC) isozymes. Isolated Langendorff-perfused rabbit hearts were subjected to 45-min ischemia (Isc) followed by 120-min reper...

A new model of Interphase Power Controller (IPC) for controlling active power is introduced in this paper. In this model, which is called VSC-based IPC, the voltage source converter (VSC) does the function of the phase shifting transformer (PST) in IPC. This new structure not only has the features of IPC, but also controls the output power effectively when the input power is changed by alternat...

The inflammatory paradental cyst (IPC) is a relatively rarely reported lesion arising from the lateral periodontium of vital teeth. However, IPC appear to be under-represented in registers of odontogenic cysts due to the misinterpretation of IPC as infected dentigerous cysts, in particular IPC originating from third molars. IPCs exhibit some temporospatial associations with tooth eruptions and ...

Remote tusking encompasses different functionality, such as remote forking, multiple remote spawning, and task migration. In order to overcome the relatively high costs of these mechunisms, optimizations can be upplied at various levels of the underlying operating system or application. Optimizations include concurrent message transmission, increased throughput and reduced latency at the distri...

Remote tasking encompasses different functionality, such as remote forking, multiple remote spawning, and task migration. In order to overcome the relatively high costs of these mechanisms, optimizations can be applied at various levels of the underlying operating system or application.

In message based systems, interprocess communication (IPC) is a central facility. If the IPC part is ineffective in such a system, it will decrease the performance and response time. By implementing the IPC facility in hardware, the administration (scheduling, message handling, time-out supervising etc.), is reduced on the CPU , which leads to more time left for the application and a more deter...
