Cofilin promotes actin filament turnover by severing and depolymerizing actin filaments. Cofilin is inactivated by phosphorylation on Ser-3 by LIM-kinase1 (LIMK1) and is activated when protein phosphatase Slingshot-1L (SSH1L) dephosphorylates this residue. The authors have shown that Ca-induced cofilin dephosphorylation is mediated by calcineurin(More)
The Akt/NF-κB pathways are involved in numerous anti-apoptotic and drug-resistance events that occur in non-small cell lung cancer (NSCLC). In the present study, the role of 7,8-dihydroxycoumarin in the regulation of the anti-apoptotic Akt and NF-κBp65 signaling pathways was explored. A549 human lung adenocarcinoma cells were exposed to(More)
The technique of computer-assisted pedicle screw installation and its clinical benefit as compared with conventional pedicle screw installation was evaluated. Twenty-two patients had thoracic screw insertion under 3-dimentional computer-assisted navigation (92 screws) and 20 patients under conventional fluoroscopic control (84 screws). The 2 groups were(More)
OBJECTIVE To study the clinical application of heterogenous bone graft combined with auto-marrow. METHODS Deproteinated and degreased heterogenous cancellous bone combined with auto-marrow was used in 21 cases of anterior cervical interbody fusion. Among them, 2 cases were treated by bone graft only, and the other 19 cases were further treated by anterior(More)
More adults are suffering from adult idiopathic scoliosis and seeking treatment for their spinal deformities. Adult idiopathic scoliosis can lead to painful spinal osteoarthritis, progressive deformity, spinal stenosis with radiculopathy, muscle fatigue from coronal and sagittal plane imbalance, and psychological effects with a visible deformity. Primary(More)
INTRODUCTION Bone marrow-derived mesenchymal stem cells (MSCs) are capable of differentiating into osteoblasts and adipocytes. This critical balance between osteoblast and adipocyte differentiation plays a significant role in maintaining normal bone homeostasis. In osteoporosis, a metabolic bone disease seen mainly in postmenopausal women because of(More)
PURPOSE Non-small cell lung cancer (NSCLC) is the leading worldwide source of cancer-related deaths. Although some drugs targeting epidermal growth factor receptor (EGFR) mutations have been developed, most advanced NSCLC is still incurable and new targets for anticancer drugs are in demand. BRCA1-associated protein-1 (BAP1) is a component of the ubiquitin(More)
OBJECTIVE To investigate the role of Zinc finger X-chromosomal protein (ZFX) in oncogenesis of Osteosarcoma tumor. METHODS Here, we first conducted an expression analysis of ZFX in Osteosarcoma cell lines. Then, we constructed ZFX-specific small interfering RNA (siRNA)-lentiviral vector that is capable of effectively inhibiting the expression of ZFX gene(More)
To analyze the radiation exposure of surgeon in spine surgery and compare computer-assisted navigation and conventinal technique. While performing spine surgery, the surgeon is exposed to a significant amount of radiation. Spinal surgeons should be considered as workers of radiational occupation accordingly. Methods of reducing radiation exposure should be(More)
BACKGROUND The result would be disastrous if the superior pulmonary sulcus tumor (Pancoast tumor) was misdiagnosed as degenerative cervical spine diseases. The aim of this study was to investigate the differential diagnosis methods of cervical radiculopathy and superior pulmonary sulcus tumor. METHODS Clinical manifestations, physical, and radiological(More)
