In recent years, Distributed Hash Tables (DHTs) have been proposed as a fundamental building block for large scale distributed applications. Important functionalities such as searching have been added to the DHT's basic lookup capability. However, supporting range queries efficiently remains a difficult problem. In this paper, we describe an adaptive(More)
Acid-sensing ion channels (ASICs) composed of ASIC1a subunit exhibit a high Ca(2+) permeability and play important roles in synaptic plasticity and acid-induced cell death. Here, we show that ischemia enhances ASIC currents through the phosphorylation at Ser478 and Ser479 of ASIC1a, leading to exacerbated ischemic cell death. The phosphorylation is(More)
The anterior cingulate cortex (ACC) is critically involved in processing the affective component of pain sensation. Visceral hypersensitivity is a characteristic of irritable bowel syndrome. Electrophysiological activity of the ACC with regard to visceral sensitization has not been characterized. Single ACC neuronal activities in response to colorectal(More)
Acid-sensing ion channels (ASICs) are ligand-gated cation channels activated by extracellular protons. In periphery, they contribute to sensory transmission, including that of nociception and pain. Here we characterized ASIC-like currents in dorsal horn neurons of the rat spinal cord and their functional modulation in pathological conditions. Reverse(More)
MicroRNAs (miRNAs) are involved in carcinogenesis and tumor progression by regulating post-transcriptional gene expression. However, the miRNA-mRNA regulatory network is far from being fully understood. The objective of this study is to identify the colorectal cancer (CRC) specific miRNAs and their target mRNAs using a multi-step approach. A multi-step(More)
p53-binding protein 1 (P53BP1), a central transducer of DNA-damage signals to p53, is required for both intra-S-phase and G2-M checkpoints, suggesting that these two proteins may work together in the p53-mediated transcriptional activation and DNA damage-repair signaling pathways. Because the p53-binding region of 53BP1 maps to the C-terminal BRCT domains,(More)
The number of vertebrae is an economically important trait that affects carcass length and meat production in pigs. A major quantitative trait locus (QTL) for thoracic vertebral number has been repeatedly identified on pig chromosome (SSC) 7. To dissect the genetic basis of the major locus, we herein genotyped a large sample of animals from 3 experimental(More)
