Thirty-three patients (24 males and nine females) with brain abscesses resulting from infection by aerobic Gram-negative bacilli were identified at Kaohsiung Chang Gung Memorial Hospital over a period of 14 years. Of these, 23 cases developed spontaneously, with the remaining ten postneurosurgery. The organisms most frequently involved were Klebsiella (K.)(More)
A number of previous studies indicated that ischemia-reperfusion injury causes two distinct types of cell death--necrosis and apoptosis--in the central nervous system. It was also implicated that the intensity of injury can somehow affect the cell death mechanisms. By occluding the descending thoracic aorta with or without simultaneously induced hypovolemic(More)
MicroRNAs (miRNAs) are a class of highly conserved, non-coding RNAs involved in post-transcriptional gene regulation. The muscle-specific miRNAs, miR-1, miR-133a, and miR-206, are expressed in skeletal muscles and have been shown to contribute to muscle development. To profile their expression after sciatic nerve denervation and reinnervation, the soleus(More)
Previously we demonstrated benefits of inhibiting the extracellular signal-regulated kinases 1/2 (ERK1/2) signaling pathway in spinal cord ischemia/reperfusion (I/R) injury. To further identify the underlying mechanisms, we investigated the impact of ERK inhibition on apoptosis and cellular protective mechanisms against cell death. Spinal cord I/R injury(More)
Traumatic brain injury (TBI) leads to important and deleterious neuroinflammation, as evidenced by indicators such as edema, cytokine production, induction of nitric oxide synthase, and leukocyte infiltration. After TBI, cerebral vascular endothelial cells play a crucial role in the pathogenesis of inflammation. In our previous study, we proved that(More)
BACKGROUND AND PURPOSE Rebleeding in spontaneous intracerebral hemorrhage (ICH) is a major cause of morbidity and mortality among stroke survivors. Due to the links between inflammation and rebleeding, we hypothesized that the biomarkers of inflammation are associated with the pathogenesis of rebleeding in ICH. We sought to investigate whether these(More)
BACKGROUND To compare the microRNA (miRNA) expression profiles in neurons and innervated muscles after sciatic nerve entrapment using a non-constrictive silastic tube, subsequent surgical decompression, and denervation injury. METHODS The experimental L4-L6 spinal segments, dorsal root ganglia (DRGs), and soleus muscles from each experimental group (sham(More)
BACKGROUND To profile the expression of microRNAs (miRNAs) and their potential target genes in the gracilis muscles following ischemic injury in rats by monitoring miRNA and mRNA expression on a genome-wide basis. METHODS Following 4 h of ischemia and subsequent reperfusion for 4 h of the gracilis muscles, the specimens were analyzed with an Agilent rat(More)
The clinical data of 62 adult patients who suffered post-neurosurgical nosocomial bacterial meningitis, retrospectively collected over a 16-year period, were studied. Cases were divided into two groups based on the date of presentation, the first period being 1986-1993 and the second 1994-2001. Fever and progressive consciousness disturbance were the most(More)
BACKGROUND The aim of this study is to assess the efficacy of pulsed RF lesioning of cervical medial branches in patients with whiplash-related chronic cervical zygapophysial joint pain in whom other conservative treatments failed. METHODS Cervical zygapophysial joint pain was confirmed in 14 patients undergoing double diagnostic blocks. These patients(More)
