We present here a combined GC-MS and LC-MS metabolic profiling approach to unraveling the pathological outcomes of aristolochic acid (AA)-induced nephrotoxicity. Urine samples were analyzed by GC-MS and LC-MS in combination with pattern recognition techniques, e.g. principal component analysis (PCA), orthogonal projection to latent structure-discriminant analysis. The work indicates that AA-ind...

We study the problem of mining frequent value sets from a large sensor network. We discuss how sensor stream data could be represented that facilitates efficient online mining and propose the interval-list representation. Based on Lossy Counting, we propose ILB, an intervallist-based online mining algorithm for discovering frequent sensor value sets. Through extensive experiments, we compare th...

introduction: it is believed that locus coeruleus (lc) influences the sensory information processing. however, its role in cortical surround inhibitory mechanism is not understood. in this experiment, using controlled mechanical displacement of whiskers we investigated the effect of phasic electrical stimulation of lc on response of layer v barrel cortical neurons in anesthetized rat. methods: ...

Introduction: Noradrenergic cells in LC participate in the process of cortical activation and behavioral arousal. The evidence suggests that locus ceoruleus (LC) plays an important role in the sleep-wake cycle. The aim of this study was stereological estimation of cavity caused by lesion and assessment of sleep stages after bilateral lesion of the LC. Materials and Methods: Male Wistar rats we...

The inferior colliculus (IC) and the locus coeruleus (LC) are two midbrain nuclei that integrate multimodal information and play a major role in novelty detection to elicit an orienting response. Despite the reciprocal connections between these two structures, the projection pattern and target areas of the LC within the subdivisions of the rat IC are still unknown. Here, we used tract-tracing a...

--Coupled LC oscillators are known to provide good performance in terms of phase noise, signal amplitude, power consumption, and quadrature output signals. However, IQ amplitude and phase mismatches in these oscillators can be quite large due to the serious mismatch problem of large area inductors and varactors. A simple design modification of the coupled LC oscillators shows a significant impr...

Introduction: It has been shown that orexin peptides have a role in opioid withdrawal behaviors. Orexin-expressing neurons that are present in the hypothalamic nuclei send dense projections to the Locus Coeruleus (LC). Withdrawal syndrome is temporally associated with hyperactivity of LC neurons. However, LC neurons do not show withdrawalinduced hyperactivity in the brain slices from morphin...

A panel discussion regarding digital archiving efforts by the U.S. Library of Congress (LC). In December 2000 Congress authorized LC to develop and execute a plan for a National Digital Information Infrastructure and Preservation Program (NDIIPP). LC developed a plan, in collaboration with other federal and nonfederal entities, to build a national network of organizations with responsibilities ...
