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)
Liver injury is known to often progress even after the hepatotoxicant is dissipated. The hydrolytic enzyme calpain, which is released from dying hepatocytes, destroys the surrounding cells and results in progression of injury. Therefore, control of calpain activation may be a suitable therapeutic intervention in cases of fulminant hepatic failure. This(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)
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)
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)
OBJECT Insulin-like growth factor-I (IGF-I) has been shown to be a potent neurotrophic factor that promotes the growth of projection neurons, dendritic arborization, and synaptogenesis. Its neuroprotective roles may be coordinated by activation of Akt, inhibition of glycogen synthase kinase-3beta (GSK-3beta), and thus inhibition of tau phosphorylation. The(More)
Aberrant calpain activation is a key mediator of neuron death. We examined the cell-permeable calpain inhibitor MDL28170 in the pathophysiological processes after spinal cord injury (SCI) including p35-p25- cyclin-dependent kinase-5 (Cdk5) activation, tau hyperphosphorylation, neuron cell death, calpain I activation, astrogliosis, and microglia activation.(More)
Oxidative stress has been implicated in the propagation of acute liver injury. The aim of our study was to investigate whether gene transfer of alpha-melanocyte-stimulating hormone (alpha-MSH), a potent anti-inflammatory peptide, could prevent fulminant hepatic failure in mice. Acute liver damage was induced by intraperitoneal administration of(More)
Integration of inorganic sulfate into biological molecules plays an important role in biological systems and is directly involved in the instigation of diseases. Protein tyrosine sulfation (PTS) is a common post-translational modification that was first reported in the literature fifty years ago. However, the significance of PTS under physiological(More)
