OBJECTIVE To determine the role of altered brain connectivity in patients with psychogenic non-epileptic seizures (PNES). METHODS Patients with PNES and age- and sex-matched healthy control subjects were enrolled. Participants underwent neuropsychological evaluation (anxiety, depression and dissociation) and interictal scalp electroencephalography (EEG).(More)
Discriminating psychogenic nonepileptic seizures (PNES) from epilepsy is challenging, and a reliable and automatic classification remains elusive. In this study, we develop an approach for discriminating between PNES and epilepsy using the common spatial pattern extracted from the brain network topology (SPN). The study reveals that 92% accuracy, 100%(More)
The capsaicin receptor, also known as 'transient receptor potential vanilloid receptor subtype 1' (TRPV1, VR1), is an ion channel subunit expressed in primary afferent nociceptors, which plays a critical role in pain transduction and thermal hyperalgesia. Increases in nociceptor TRPV1 mRNA and protein are associated with tissue injury-inflammation. As(More)
Vanilloid receptor subtype-1 (VR1) is a nonselective cation channel that is expressed in sensory neurons and is activated by multiple noxious stimuli. Rat Vr1, stretch-inactivated channel (SIC), and vanilloid receptor 5' splice variant (VR.5'sv) have been hypothesized to be derived from a common VR gene. Characterization of the genomic structure encoding(More)
The peripheral detection of painful stimuli requires the activation of small-diameter primary afferent neurons known as nociceptors. We have exploited two features of nociceptor biology, expression of the high affinity receptor for nerve growth factor (TrkA) and sensitivity to capsaicin, to isolate novel proteins using a differential display cloning scheme.(More)
There has been an increasing interest in using unlabeled data in semi-supervised learning for various classification problems. Previous work shows that unlabeled data can improve or degrade the classification performance depending on whether the model assumption matches the ground-truth data distribution, and also on the complexity of the classifier(More)
Heparan sulfate (HS) proteoglycans (HSPGs) bind to multiple growth factors/morphogens and regulate their signaling. 6-O-sulfation (6S) of glucosamine within HS chains is critical for many of these ligand interactions. Sulf-1 and Sulf-2, which are extracellular neutral-pH sulfatases, provide a novel post-synthetic mechanism for regulation of HSPG function by(More)
Super-Resolution is the problem of generating one or a set of high-resolution images from one or a sequence of low-resolution frames. Most methods have been proposed for super-resolution based on multiple low resolution images of the same scene, which is called multiple-frame super-resolution. Only a few approaches produce a high-resolution image from a(More)
