The analysis of biological information from protein sequences is important for the study of cellular functions and interactions, and protein fold recognition plays a key role in the prediction of protein structures. Unfortunately, the prediction of protein fold patterns is challenging due to the existence of compound protein structures. Here, we processed(More)
Spiking neural P systems with anti-spikes (ASN P systems, for short) are a class of distributed parallel computing devices inspired from the way neurons communicate by means of spikes and inhibitory spikes. ASN P systems working in the synchronous manner with standard spiking rules have been proved to be Turing completeness, do what Turing machine can do.(More)
The stress-activated protein kinase c-Jun N-terminal kinase (JNK) is a central regulator in neuronal death cascades. In animal models of cerebral ischemia, acute inhibition of JNK reduces infarction and improves outcomes. Recently however, emerging data suggest that many neuronal death mediators may have biphasic properties-deleterious in the acute stage(More)
Remote ischemic postconditioning (RIPostC) has been proved to protect the brain from stroke, but the precise mechanism remains not fully understood. In the present study, we aimed to investigate whether RIPostC attenuates cerebral ischemia-reperfusion injury by abating endoplasmic reticulum (ER) stress response. CHOP, a multifunctional transcription factor(More)
The mechanism and long-term consequences of early blood-brain barrier (BBB) disruption after cerebral ischaemic/reperfusion (I/R) injury are poorly understood. Here we discover that I/R induces subtle BBB leakage within 30-60 min, likely independent of gelatinase B/MMP-9 activities. The early BBB disruption is caused by the activation of ROCK/MLC(More)
Local infusion of low dose erythropoietin (EPO) alleviates cerebral ischemia and reperfusion (I/R) injury in rats; however, the underlying molecular mechanisms are still unclear. The present study investigated the effect of low dose EPO treatment on I/R-induced endoplasmic reticulum (ER) stress in brain tissue and isolated microvessels in rodents.(More)
Inhibitor of apoptosis-stimulating protein of p53 (iASPP), encoded by PPP1R13L gene, is often overexpressed in human cancers. From the PPP1R13L gene, at least two isoforms, iASPP-L and iASPP-SV, are produced through alternative splicing. However, the role of these isoforms in glioma is still elusive. In this study, we examined the expression of iASPP-SV in(More)
