In a wireless packet (ATM) network that supports an integrated mix of multimedia traffic, the channel access protocol needs to be designed such that mobiles share the limited communications bandwidth in an eficient manner: maximizing the utilization of the frequency spectrum and minimizing the delay experienced by mobiles. In this paper, we propose and(More)
Bipolar disorder (BD) is a debilitating mental disorder that cannot be diagnosed by objective laboratory-based modalities. Our previous studies have independently used nuclear magnetic resonance (NMR)-based and gas chromatography-mass spectrometry (GC-MS)-based metabonomic methods to characterize the urinary metabolic profiles of BD subjects and healthy(More)
Prenatal choline supplementation can protect rats against cognitive deficits induced by status epilepticus induced by the cholinergic agent pilocarpine [J. Neurosci. 20 (2000) 1]. In the present day, we have extended this novel finding by investigating the effects of pre- and postnatal choline supplementation in memory deficits associated with status(More)
Tau hyperphosphorylation and memory deficit are characteristic alterations of Alzheimer's disease (AD). Protein phosphatases (PP) 2A plays a crucial role in AD-like lesions. Inhibition of PP2A through hippocampal injection of okadaic acid (OA) induces tau hyperphosphorylation and memory impairment of rats. By using this model, we explored in the present(More)
Autonomic computing middleware is a promising way to enable middleware based systems to cope with the rapid and continuous changes in the era of Internet. Technically, there have been three fundamental and challenging capabilities to an autonomic computing middleware, including how to monitor, reason and control middleware platform and applications. This(More)
OBJECTIVE The goal of this study was to investigate the potential protective effects of nimodipine (ND), a calcium channel blocker, on the acute manifestations and long-term behavioral sequalae of experimental status epilepticus (SE). METHODS Three groups of Postnatal Day (P) 35 rats undergoing kainic acid (KA)-induced SE were injected with phenobarbital(More)
