A xylanase gene was PCR-cloned from Thermoanaerobacterium saccharolyticum and expressed in Escherichia coli. The xylanase (XynA) consisted of a signal peptide, glycoside hydrolase family 10 domains, carbohydrate-binding modules, and surface layer homology domains. It was optimally active at 70–73°C and at pH 5–7. It had enhanced activity with NaCl with(More)
PURPOSE Reasons for worldwide variability in the burden of primary malignant brain and central nervous system (CNS) tumors remain unclear. This study compares the incidence and survival of malignant brain and CNS tumors by selected histologic types between the United States (US) and Taiwan. METHODS Data from 2002 to 2010 were selected from two(More)
BACKGROUND Traumatic spinal cord injury (SCI) is a major cause of long-term disability. However, therapeutic agents targeting SCI are sorely lacking. The aim of this study was to investigate whether curcumin has neuroprotective effects after SCI in rats. MATERIALS AND METHODS Studies were performed in 39 male Sprague-Dawley rats after spinal cord(More)
Hypoxic-ischemic (H-I) encephalopathy is a major contributor to morbidity and mortality in infants and children. To delineate the nature and mechanism(s) of neuroprotection via erythropoietin (EPO) gene therapy, we evaluated the effects of single intravenous injection of naked plasmid DNA encoding EPO in H-I infant rats. Single administration of naked(More)
PURPOSE To compare the measurement of refractive errors (sphere, cylinder, and axis) between the hand-held Retinomax and on-table Topcon autorefractors in cyclopleged and noncyclopleged young children. The average bias and measurement agreement were assessed. DESIGN Observational cross-sectional study. METHODS The study included 114 cyclopleged and 156(More)
STUDY DESIGN A case report with a literature review is presented. OBJECTIVE To describe and review the clinical presentations, characteristic findings from imaging studies, and treatment of traumatic spinal subdural hematoma. SUMMARY OF BACKGROUND DATA Traumatic spinal subdural hematoma is uncommon, and only eight cases have been reported in the(More)
We studied the vulnerability of the spinal cord to extracorporeal shock wave treatment (ESWT). In this experiment, 12 rabbits were divided into three groups (4 in each group). All animals underwent a preceding lumbar laminectomy at L4 1 week before ESWT. In group 1, 2000 impulses of high dose (0.62 mJ/mm2 energy flux density) shockwave energy were applied(More)
BACKGROUND Extracorporeal shock wave treatment has been used to treat many orthopedic disorders. However, the effect of extracorporeal shock waves on spinal fusion has not been reported. METHODS Fifteen rabbits were used in this study. Spinal fusion was performed with decortication of bilateral L5 and L6 transverse processes, and placement of the bone(More)
INTRODUCTION Recurrence of chronic subdural haematoma (CSDH) occurs in up to 30% of patients. The rate of recurrence is higher in bilateral versus unilateral CSDH and the reason for this has not been fully elucidated. There are few quantitative studies of temporal changes in brain re-expansion after haematoma evacuation. The aim of this study is to use a(More)
OBJECT Glioblastoma multiforme (GBM) is the most common and lethal primary brain tumor in adults. It is nearly uniformly fatal, with a median survival time of approximately 1 year, despite modem treatment modalities. Nevertheless, a range of survival times exists around this median. Efforts to understand why some patients live longer or shorter than the(More)
