The purpose of this experiment was to determine the stimulating and recording characters of fascicular physioelectrical signals in the activity of peripheral nerves by longitudinally implanted intrafascicular electrodes (LIFEs) in a rabbit sciatic nerve model, and discuss the future application of LIFEs in functional electrical stimulation (FES) and control(More)
Successful placement of cervical pedicle screws requires accurate identification of both entry point and trajectory. However, literature has not provided consistent recommendations regarding the direction of pedicle screw insertion and entry point location. The objective of this study was to define a guideline regarding the optimal entry point and(More)
By detection and analysis of neuro-information from amputee in experiments, a research on the correlations of three main nerves (median nerve, radial nerve and ulnar nerve), on the patterns for discharging information, and on the mechanics about how neuro-information dominates movements was performed. These researches would contribute to the development of(More)
The aim of this study is to investigate the role of miR-9 and its mechanism on the osteoblast differentiation of mesenchymal stem cells. Real-time PCR and western blotting were used to study gene expression. Assay of Alkaline phosphatase activity and alizarin red staining were used to examine osteoblast differentiation. Transfection of miR-9 mimics or(More)
STUDY DESIGN In vitro biomechanical study evaluating the effect of fusion levels on simulated S1 screws on calf spines. OBJECTIVE To measure the stresses of simulated S1 screws as a function of increasing fusion levels in long-fusion construct. SUMMARY OF BACKGROUND DATA Extension of long fusion to sacrum remains a difficult clinical challenge despite(More)
The polymeric title compound, {[Ba(2)(C(9)H(4)N(2)O(4))(2)(H(2)O)]·4.5H(2)O}(n), adopts a layer structure parallel to (001) in which adjacent Ba(II) atoms are connected by two benzimidazole-5,6-dicarboxyl-ate dianions, one functioning in a μ(4)-bridging mode and the other in a μ(5)-bridging mode. The Ba atom having water in its coordination environment as(More)
OBJECTIVE Ossification of the ligamentum flavum (OLF) is a rare cause of thoracic myelopathy. The aim of this study was to identify factors associated with the surgical outcome on the basis of preoperative clinical and radiological findings. METHODS Data obtained in 26 patients whot underwent posterior decompression for thoracic myelopathy, caused by(More)
The purpose of this experiment was to study the recording and stimulating properties, and biocompatibility of longitudinally implanted intrafascicular electrodes (LIFEs) in a rabbit sciatic nerve model when they were chronically implanted into peripheral fascicles. LIFEs were implanted chronically into sciatic nerve fascicles of rabbits as recording and(More)
OBJECTIVE To study the biocompatibility of longitudinally implanted intrafascicular electrodes (LIFEs) in a rabbit sciatic nerve model. And to discuss the possibility of peripheral fascicular signals as a new signal source to control an electronic prosthetic hand. METHODS LIFEs were implanted chronically into sciatic peripheral fascicles of rabbits as(More)
