Background: This study evaluated whether IMRT using fewer beams and segments could reduce delivery time without compromising plan quality in gastric cancer adjuvant radiotherapy. Materials and Methods: Fifteen patients with advanced gastric cancer who underwent D2, R0 surgery were included in this study. IMRT plans for each patient were designed as 7 equal beams with 40 segments, 5 beams with 2...

acute paraplegia is a rare but catastrophic complication of surgeries performed on aorta and corrective operations of vertebral column. trauma to spinal cord after spinal anesthesia and ischemia of spinal cord also may lead to acute paraplegia. acute paraplegia as a complication of general anesthesia in surgeries performed on sites other than aorta and vertebral column is very rare. here we pre...

abstract   objective: to evaluate and review our experience with pediatric spinal injuries and factors affecting outcome, the authors conducted a retrospective clinical study of 43 cases (32 boys, 11 girls) of pediatric spine injuries treated during four years (january 1999 to december 2003).   methods: forty-three children with spinal injuries were studied retrospectively over four years and w...

AIM Analysis of developmental role of fibronectin during differentiation of the human spinal cord, nerves, and ganglia. METHODS Seven normal human embryos and fetuses between the 7th and 9th developmental week and a 9-week fetus with cervical spina bifida were histologically examined on hematoxylin and eosin stained serial paraffin sections of thoracic axial segments. Monoclonal antibody to t...

Studies of the regulation of total spinal cord blood flow have been limited by methodology. Total flow has been difficult to measure and flow to the gray and white matter within the cord has not been previously assessed. We have used labeled microspheres to measure blood flow in the spinal cord. Our purpose was to examine the effects of several physiological stimuli on the regulation of blood f...

Background and Objective: Evaluation of degenerative changes of motoneurons and their related synapses can be useful in understanding the mechanisms of neurodegenerative diseases and their potential treatment. The present electron microscopic and immunohistochemical study investigates the axotomy-induced...

Introduction: Intramedullary ependymoma (IE) is adults' most common intramedullary spinal tumor. Tumors usually extend one to eight segments in the cervical region. In this case report, we reported a patient with massive IE spanning from fourth ventricle T4 segment of cord, which surgically treated laminectomy occiput Case Presentation: A 42-year-old man who known progressive upper extremities ...

The regional distribution of spinal cord networks producing locomotor-like, as well as non-locomotor-like, activity was studied with the use of an in vitro neonatal rat preparation. Rhythmic activity was induced by bath application of either serotonin (5-HT), acetylcholine (ACh), N-methyl-D,L-aspartate (NMA), or combined 5-HT/NMA, and was monitored via hindlimb flexor (peroneal) and extensor (t...

BACKGROUND This study examined the prognostic factors that affect the surgical outcome of laminoplasty in cervical spondylotic myelopathy patients by comparative analysis. METHODS Thirty nine patients, 26 males and 13 females, who were treated with laminoplasty for cervical myelopathy from September 2004 to March 2008 and followed up for 12 months or longer, were enrolled in this study. The m...
