Opioid and tachykinin systems are involved in modulation of pain transmission in the spinal cord. Regulation of surface opioid receptors on nociceptive afferents is critical for opioid analgesia. Plasma-membrane insertion of delta-opioid receptors (DORs) is induced by stimulus-triggered exocytosis of DOR-containing large dense-core vesicles (LDCVs), but how(More)
—A power and area efficient sensor interface consumes 6.4 mW from 1.2 V while occupying 5 mm 5 mm in 0.13 m CMOS. The interface offers simultaneous access to 96 channels of broadband neural data acquired from cortical microelectrodes as part of a head-mounted wireless recording system, enabling basic neuroscience as well as neuroprosthetics research.(More)
The use of high throughput screening (HTS) to identify lead compounds has greatly challenged conventional quantitative structure-activity relationship (QSAR) techniques that typically correlate structural variations in similar compounds with continuous changes in biological activity. A new QSAR-like methodology that can correlate less quantitative assay(More)
Plants have evolved sophisticated systems for adaptation to their natural habitat. In response to developmental and environmental cues, plants produce and perceive jasmonate (JA) signals, which induce degradation of JASMONATE-ZIM-Domain (JAZ) proteins and derepress the JAZ-repressed transcription factors to regulate diverse aspects of defense responses and(More)
A power and area efficient sensor interface consumes 6.5 mW from 1.2 V supplies while occupying 5 mm x 5 mm in 0.13 µm CMOS. The interface enables full bandwidth access to 96 channels of data acquired from cortical microelectrodes as part of a head-mounted wireless recording system for unconstrained primate neuroscience experiments. Open loop amplification(More)
The application of three-dimensional H-suppressed BCUT metrics (BCUTs) in binary QSAR analysis was investigated using carbonic anhydrase II inhibitors and estrogen receptor ligands as test cases. Variable selection was accomplished with a genetic algorithm (GA). Highly predictive binary QSAR models were obtained for both sets of compounds within 200 GA(More)
PTEN is a tumour suppressor frequently mutated in many types of cancers. Here we show that targeted disruption of PTEN leads to neoplastic transformation of human neural stem cells (NSCs), but not mesenchymal stem cells. PTEN-deficient NSCs display neoplasm-associated metabolic and gene expression profiles and generate intracranial tumours in(More)
Polyploidization results in genome duplication and is an important step in evolution and speciation. The Malus genome confirmed that this genus was derived through auto-polyploidization, yet the genetic and meiotic mechanisms for polyploidization, particularly for aneuploidization, are unclear in this genus or other woody perennials. In fact the(More)
α-Synuclein (α-syn), a protein involved in the pathogenesis of Parkinson's disease (PD), is known to accumulate in mitochondria, disrupt mitochondrial function. However, the molecular mechanisms that link these pathological responses have not been investigated. In rats overexpressing α-syn in the substantia nigra (SN) through adeno-associated virus (AAV)(More)
