BACKGROUND The purpose of our study was to determine the functional role of microRNA (miR)-16 in chronic inflammatory pain and to disclose its underlying molecular mechanism. MATERIAL AND METHODS Inflammatory pain was induced by injection of complete Freund's adjuvant (CFA) to Wistar rats. The pWPXL-miR-16, PcDNA3.1- Ras-related protein (RAB23), and/or SB203580 were delivered intrathecally to the rats. Behavioral tests were detected at 0 h, 4 h, 1 d, 4 d, 7 d, and 14 d after CFA injection. After behavioral tests, L4-L6 dorsal spinal cord were obtained and the levels of miR-16, RAB23, and phosphorylation of p38 (p-p38) were evaluated by quantitative real-time PCR (qRT-PCR)...

Neurulation, the early embryonic process of forming the presumptive brain and spinal cord, is highly complex and involves hundreds of genes in multiple genetic pathways. Mice have long served as a genetic model for studying human neurulation, and the resulting neural tube defects (NTDs) that arise when neurulation is disrupted. Because mice appear to show mostly single gene inheritance for NTDs and humans show multifactorial inheritance, mice sometimes have been characterized as a simpler model for the identification and study of NTD genes...

Electrophysiological recordings from spinal cord slices have proven to be a valuable technique to investigate a wide range of questions, from cellular to network properties. We show how to prepare viable oblique slices of the spinal cord of young mice (P2 - P11). In this preparation, the motoneurons retain their axons coming out from the ventral roots of the spinal cord. Stimulation of these axons elicits back-propagating action potentials invading the motoneuron somas and exciting the motoneuron collaterals within the spinal cord...

BACKGROUND: The major complication faced by patients with chronic static spinal cord injury (SCI) is the loss of mobilization. With the aim to rehabilitate SCI patients, physiotherapy is performed worldwide. However, it only helps the patients to live with their disabilities. An interdisciplinary management involving human embryonic stem cell (hESC) therapy along with physiotherapy as a supportive therapy offers regenerative treatment of the patients with SCI. MAIN BODY: The present study focuses on the role of physiotherapy in the mobilization of patients with SCI (paraplegic 136; tetraplegics 90) undergoing hESC therapy...

A 16-year-old male patient with Ehler-Danlos syndrome (EDS) and a back deformity since birth presented with severe kyphoscoliosis. The patient was neurologically intact but had respiratory and cardiac insufficiencies. A two-stage vertebral column resection (VCR) at T9-T10 with multiple level fusion with multimodality intraoperative neurophysiological monitoring (IONM) was planned.  During the first stage, pedicle screws were placed at multiple spinal levels above and below the VCR level. Upper and lower somatosensory evoked potentials (SSEP), transcranial electrical motor evoked potentials (TCeMEP), and electromyography were monitored continuously and showed no significant changes...

Intravesical botulinum toxin A (BoNTA) injection has been widely used for the treatment of detrusor overactivity in patients with neurogenic bladder due to spinal cord injury who do not respond to conventional treatment. There is no consensus about antibiotic prophylaxis for this procedure. We conducted a retrospective analysis of medical records of adult patients with spinal cord injury who underwent detrusor BoNTA injection between January of 2007 and December of 2013 in a rehabilitation hospital. Occurrence of symptomatic urinary tract infection (UTI) was assessed in 3 groups in accordance with their use of antibiotics (prophylactic dosage, 3 days, more than 3 days) for the treatment of asymptomatic bacteriuria...

Professor Emil Redlich (1866-1930) of the University of Vienna was born 150 years ago. Raised in a humble environment, he became an eminent researcher and neurology scholar, and succeeded in laying some of the key foundations of neuroanatomy and neuropathology. His name is linked to medical eponyms that define the dorsal root entry zone into the spinal cord, epidemic disseminated encephalomyelitis, narcolepsy, senile plaques and dementia. As its first director, he managed to organize the Maria-Theresien-Schlössel into a first-class neuropsychiatric hospital...

Tetrandrine (TET) is a bis-benzylisoquinoline alkaloid, which is isolated from a Chinese medicinal herb with antioxidant and anti-inflammatory activities. In this study, we investigated the effects of TET on oxygen-glucose-serum deprivation/reoxygenation (OGSD/R)-induced injury in rat spinal cord astrocytes, which mimics hypoxic/ischemic conditions in vivo. MTT and LDH assays indicated that cell viability was distinctly reduced and LDH leakage was elevated after OGSD/R exposure, which were dose-dependently reversed by pretreatment with TET (0...
