Despite 2-methoxyestradiol (2ME2) and tricyclodecan-9-yl-xanthogenate (D609) having multiple effects on cancer cells, mechanistically, both of them down-regulate hypoxia-inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF). We hypothesize HIF-1alpha plays an essential role in cerebral ischemia as a pro-apoptosis regulator; 2ME2(More)
Hypoxia-inducible factor-1 (HIF-1) plays an essential role in cerebral ischemia as a proapoptotic factor. We hypothesized that HIF-1alpha siRNA can protect the brain from ischemic damage by inhibiting HIF-1alpha induced apoptotic pathway at the RNA level in a rat focal ischemic model. Results showed that treatment with HIF-1alpha siRNA reduced the infarct(More)
RNA interference appears to have a great potential not only as an in vitro target validation, but also as a novel therapeutic strategy based on the highly specific and efficient silencing of a target gene. We hypothesize that MMP-9 siRNA can be effective as an MMP-9 protein inhibitor in a rat focal ischemia model. Male Sprague-Dawley rats (156) were(More)
Trials of neuroprotection in ischemic stroke mainly concern gray matter protection, with little information on white matter damage. Olfactory ensheathing cells (OECs) are capable of providing continuous neurotrophic factor and of promoting growth and remyelination of damaged axons. We evaluated OECs for the repair of white matter after transplantation in(More)
The microanatomy of the superior orbital fissure (SOF) was studied in 96 sides of cadaver specimens. The SOF is a narrow bony cleft that lies at the apex of the orbit between the greater and lesser wings of the sphenoid. Through this fissure, many important structures enter the orbit from the middle cranial fossa including the third, fourth, sixth cranial(More)
