OBJECTIVE Use of instrumentation in spinal osteomyelitis remains controversial because of the perceived risk of persistent infection related to a devitalized graft and spinal hardware. Particularly, limited information is available regarding the long-term follow-up of patients. We retrospectively reviewed the use of titanium mesh-bone graft composite after(More)
BACKGROUND AND PURPOSE Cerebral venous ischemia often induces severe brain edema. Vascular endothelial growth factor (VEGF), which induces angiogenesis, is also known as vascular permeability (VP) factor. The present study was undertaken to investigate whether the inhibition of VEGF could reduce brain edema formation and cerebral venous infarction (CVI) in(More)
A 12 year-old girl was treated with prophylatic cranial irradiation for acute lymphoblastic leukaemia (ALL). At the age of 39, she was admitted to our hospital for status epilepticus. Computed tomography demonstrated two, enhancing bilateral sided intracranial tumors. After surgery, this patient presented meningiomas which histologically, were of the(More)
BACKGROUND The increasing number of neurosurgical procedures for elderly patients and the development of skull base neurosurgery have increased interest in cerebral venous injury that might occur in a neurosurgical setting. Brain-derived neurotrophic factor (BDNF) may have neuroprotective effects against cerebral venous ischemia. OBJECTIVE To investigate(More)
Increased mortality after stroke is associated with development of brain edema. The aim of the present study was to examine the contribution of endothelial myosin light chain (MLC) phosphorylation to hypoxia-induced blood-brain barrier (BBB) opening. Measurements of trans-endothelial electrical resistance (TEER) were performed to analyse BBB integrity in an(More)
Photoinduced phase transitions are of special interest in condensed matter physics because they can be used to change complex macroscopic material properties on the ultrafast timescale. Cooperative interactions between microscopic degrees of freedom greatly enhance the number and nature of accessible states, making it possible to switch electronic, magnetic(More)
OBJECTIVE The incidence of spinal infections has increased in recent years, and vertebral osteomyelitis and epidural abscess are issues of great concern for spine surgeons. We retrospectively reviewed our cases treated by two-stage management for vertebral osteomyelitis and epidural abscess. METHODS The series consisted of nine patients (five men and four(More)
We report for the first time a successful fabrication and operation of an InAs/GaAs quantum dot based intermediate band solar cell concentrator photovoltaic (QD-IBSC-CPV) module to the IEC62108 standard with recorded power conversion efficiency of 15.3%. Combining the measured experimental results at Underwriters Laboratory (UL®) licensed testing laboratory(More)
