Spinal Cord Stimulation (SCS) is a neurostimulation technique used to alleviate several kinds of chronic pain. Computer modeling of SCS is a powerful tool in predicting the effects of an electrical stimulus on nerve fiber activation. The UT-SCS, developed at the University of Twente, Enschede, The Netherlands, has provided useful insights on the mechanisms of SCS. Nevertheless, this software pr...

Insulators are DNA elements that establish independent transcriptional domains within eukaryotic genomes. The Drosophila scs and scs' insulators localize near the borders of a structural domain in the polytene chromosomes, known as a puff, produced by transcription of the 87A heat shock protein (hsp) genes. It has been suggested that scs and scs' are boundary elements that delimit this deconden...

BACKGROUND While much progress has been made in understanding stem cell (SC) function, a complete description of the molecular mechanisms regulating SCs is not yet established. This lack of knowledge is a major barrier holding back the discovery of therapeutic uses of SCs. We investigated the value of a novel meta-analysis of microarray gene expression in mouse SCs to aid the elucidation of reg...

BACKGROUND Spinal cord stimulation (SCS) is a form of neuromodulation, used to treat chronic neuropathic pain refractory to conventional medical management. Spinal cord stimulators are treatment options when intractable chronic pain has not responded to more conventional treatment modalities. Currently, the use of SCS is contraindicated in pregnancy. Nevertheless, many SCS/neuromodulation recip...

In clinical practice, deep brain stimulation (DBS) is effective for treatment of motor symptoms in Parkinson's disease (PD). However, the mechanisms have not been understood completely. There are some reports that electrical stimulation exerts neuroprotective effects on the central nervous system diseases including cerebral ischemia, head trauma, epilepsy and PD, although there are a few report...

Skeletal muscle stem cells, or "satellite cells" (SCs), are required for the regeneration of damaged muscle tissue. Although SCs self-renew during regeneration, the mechanisms that govern SC re-entry into quiescence remain elusive. We show that FOXO3, a member of the forkhead family of transcription factors, is expressed in quiescent SCs (QSCs). Conditional deletion of Foxo3 in QSCs impairs sel...

An SCS consists of an open architecture, standardized media and layout, standard connection interfaces, adherence to national and international standards, and total system design and installation. Other than the structured cabling system, voice, data, video, and building management systems (BMS) have nothing in common except similar transmission characteristics (analog or digital data signals) ...

Blind spread-spectrum watermarking schemes with correlation based detection algorithms suffer significantly from host signal interference. Improvements are possible when considering the host signal as side-information to the watermark encoder. Costa showed that, in a specific case, host signal interference can be avoided completely. The scalar Costa scheme, which operates on structured codebook...

To determine the relationship of test-day (TD) somatic cell score (SCS) to TD and lactation milk yields, 1,320,590 records from Holstein first and second calvings from 1995 through 2002 were examined. All lactations had recorded yield and SCS for at least the first 4 TD. Least square analyses were conducted for yields on TD 2 through 10 within herd and cow. The model included regressions on cur...

Cardiac syndrome X (CSX) is characterized by effort angina, ST-segment depression during stress tests and normal coronary arteries. Abnormal nociception was suggested in these patients by studies showing a reduced cardiac pain threshold; furthermore, we recently found a lack of habituation to pain stimuli using recording of laser evoked potentials (LEPs). In CSX patients with severe angina, spi...
