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)
OBJECTIVES Brimonidine tartrate ophth, an alpha(2)-adrenergic agonist, is widely used as an antiglaucoma agent for lowering intraocular pressure. Recent studies suggest that brimonidine may be neuroprotective for retinal ganglion cells (RGCs) following optic nerve crush injury. Brain-derived neurotrophic factor (BDNF), a potent neuroprotective factor(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)
PURPOSE Very-low-density lipoprotein receptor (VLDLR) in knockout mice (vldlr(-/-)) has been reported to induce subretinal neovascularization. Therefore, VLDLR expression in the wild-type mouse retina was investigated and the retinal angiogenic process in vldlr(-/-) mice was characterized. METHODS VLDLR expression in the retina and in purified retinal(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)
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)
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)
Loss-of-function mutations in the gene encoding the multifunctional protein, DJ-1, have been implicated in the pathogenesis of early-onset familial Parkinson's disease (PD), suggesting that DJ-1 may act as a neuroprotectant for dopaminergic (DA) neurons. Enhanced autophagy may benefit PD by clearing damaged organelles and protein aggregates; thus, we(More)
