Hypoxia-inducible factor-1α (HIF-1α) is thought to mediate pharmacoresistance in tumor by inducing Pgp overexpression. We aimed to investigate the expression of HIF-1α and MDR1/P-glycoprotein in refractory epilepsy, to explore the correlation of HIF-1α with epilepsy multidrug resistance. We collected hippocampus and mesial temporal lobe (MTL) cortex of(More)
We have developed a new technique for the treatment of mild types of cryptotia in which the cavum conchae cartilage was pulled superiorly and sutured it to the temporal bone to the temporal parietal junction periosteum securely. Then, the stitches for bolster fixation were inserted parallel to the auricular temporal sulcus and temporarily left untied. Our(More)
BACKGROUND Although most of the patients with eosinophilic esophagitis (EoE) have mucosal and structural changes that could potentially explain their symptoms, it is unclear whether EoE is associated with abnormal esophageal motor function. The aims of this study were to evaluate the esophageal pressure topography (EPT) findings in EoE and to compare them(More)
The Notch signaling pathway has been shown to be involved in the progression of chronic myeloid leukemia (CML). The aim of this study was to investigate the effects of exogenous Notch2 overexpression on cell proliferation and possible mechanisms in the human CML cell line K562. When exogenous intracellular fragment of Notch2 (ICN2) was transfected into K562(More)
PURPOSE 4-Hydroxy-2-nonenal (4-HNE) is a major lipid peroxidation product in the retina and the retinal pigment epithelium. The purpose of the present study was to investigate how NF-E2-related factor-2 (Nrf2) and phosphatidylinositol 3 (PI3K) pathways affect the responses of cultured human retinal pigment epithelial (RPE) cells to 4-HNE. METHODS Cultured(More)
BACKGROUND Patients with vascular Ehlers-Danlos syndrome (EDS) can develop internal carotid artery (ICA) aneurysms. Any surgical procedure is hazardous and often unrewarding because of fragile blood vessels. Endovascular treatment may be an alternative approach to the treatment of ICA aneurysms in patients with vascular EDS. CASE A 23-year-old woman with(More)
