Docosahexaenoic acid (22:6n-3), one of the main structural lipids in the mammalian brain, plays crucial roles in the development and function of brain neurons. We examined the effect of docosahexaenoic acid on neuronal differentiation of neural stem cells in vitro and in vivo. Neural stem cells obtained from 15.5-day-old rat embryos were propagated as(More)
The internal fixing materials made from shape-memory alloys (SMAs) have recently been reported for long bone fracture. We present a new internal fixation technique using a cylindrical SMAs implant in a rat femoral fracture healing. The implant was designed in a shape to circumferentially fix the fractured bone using resilient SMA claws. To evaluate the(More)
BACKGROUND X-ray images of lumbar degenerative diseases often show not only claw osteophytes, but also pairs of osteophytes that form in a direction away from the adjacent disc. We have investigated the direction of the formation of anterior lumbar vertebral osteophytes across the lumbar vertebrae using a sufficient number of lumbar radiographs, because(More)
Most of the traffic accidents have been caused by driver's inattention. Therefore, driver monitoring is one of the most important challenges in order to prevent traffic accidents. Some studies for evaluating mental workload during driving have been reported; however driver's mental state should be estimated quantitatively for the future. This paper proposes(More)
INTRODUCTION Intraosseous lipoma is a benign bone tumor, and the tumor occurs more frequently in the lower extremities. We present a very rare case of intraosseous lipoma occurring in the lumbar vertebral arch and spinous process. CASE PRESENTATION A 54-year-old Japanese man presented with a three-month history of lumbar pain. Magnetic resonance imaging(More)
PURPOSE To determine characteristics responsible for improvement of low back pain after cervical laminoplasty for cervical spondylotic myelopathy. METHODS 18 men and 10 women aged 38 to 88 (mean, 71) years who had a low back pain visual analogue scale (VAS) score of 5 or more before cervical laminoplasty were included. In 12 patients the VAS score(More)
We performed cordectomy, a surgical technique that is infrequently used at present, for a patient with post-traumatic syringomyelia (following complete paraplegia of both lower limbs due to dislocation fracture of the 9th thoracic vertebra), yielding a favourable result. We recommend cordectomy as a surgical technique to which spinal surgeons should give(More)
