1. The entire central nervous system (CNS) of the newly born, South American opossum (Monodelphis domestica) was isolated and maintained in basal medium, Eagle's (BME) with 0.2% foetal calf serum and antibiotics. Isolated CNS preparations remained electrically excitable for up to 10 days. The fine structure of the spinal cord was normal after 5 days in culture: axons, synapses, dendrites and gl...

pinch technology is one of the best methods for designing a multi stream heat exchanger(mshe) through a network; current pinch-based methods, however, lead to a larger and more complicateddesign problems. the major drawback of the current methods is they result in designs having more individual mshe sections than essential, correspond to the enthalpy intervals on temperature vs. enthalpy diagra...

background: palladium-103 (103pd) is a brachytherapy source for cancer treatment. the monte carlo codes are usually applied for dose distribution and effect of shieldings. monte carlo calculation of dose distribution in water phantom due to a med3633 103pd source is presented in this work. materials and methods: the dose distribution around the 103pd model med3633 located in the center of 30×30...

OBJECTIVE To determine whether pulmonary function at discharge from inpatient rehabilitation can predict respiratory infection in spinal cord injury in the first year after discharge, and to determine which pulmonary function parameter predicts best. DESIGN Multicentre prospective cohort study. SUBJECTS A total of 140 persons with spinal cord injury. METHODS Pulmonary function was tested ...

BACKGROUND High-resolution ultrasonography is a new and promising technique to evaluate peripheral and spinal nerves. Its validity as a diagnostic tool in neurological diseases has been demonstrated in adults. Up to now no reference values have been published in children and adolescents although this technique would be ideal in this population as it is fast and non-invasive. METHODS/DESIGN Ou...

Idiopathic scoliosis is a three-dimensional deformity of the spine with lateral curvature combined with vertebral rotation. The primary lesion, however, lies in the median sagittal plane, taking the form of a lordosis. It was first described by Hippocrates, and the term “scoliosis” was first used by Galen (AD 131–201). Although the clinical manifestations of scoliosis have been well described, ...

in this paper, we study spacelike dual biharmonic curves. we characterize spacelike dual biharmonic curves in terms of their curvature and torsion in the lorentzian dual heisenberg group . we give necessary and sufficient conditions for spacelike dual biharmonic curves in the lorentzian dual heisenberg group . therefore, we prove that all spacelike dual biharmonic curves are spacelike dual heli...

Treatment of rigid and severe spinal deformities is challenging and risky. Preoperative halo-gravity traction can be used to progressively reduce the deformity before spinal fusion. The aim of this study was to evaluate the effectiveness of halo-gravity traction for the correction of severe spinal deformities. Fifteen patients were reviewed retrospectively. Their mean age at the beginning of tr...

As the internet of things (IoT) turns into the focus of software market, motion recognition has become popular in many areas, such as health care and real-time monitoring. Thus, this paper presents a motion recognition and spinal monitoring method using wearable sensors based on Hidden Markov Models (HMM) and K-means. To predict six different motions, i.e., walking, walking-upstairs, walking-do...

Cord motion at the cervical cord (C-3) level was measured with phase-contrast magnetic resonance imaging (MRI) in 39 healthy young subjects and 34 age-matched patients with spinal dysraphism. Cord velocity curves (composed of waves I, II, and III) were made in both sagittal images and transverse images and classified into 3 types. The measurement in the sagittal images were more reproducible th...
