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)
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)
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)
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 evaluate the accuracy of computer-assisted pedicle screw installation and its clinical benefit as compared with conventional pedicle screw installation techniques. METHODS Total 176 thoracic pedicle screws placed in 42 thoracic fracture patients were involved in the study randomly, 20 patients under conventional fluoroscopic control (84(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)
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)
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)
The purpose of this study was to establish a method for measuring the knee valgus angle from the anatomical and mechanical axes on three-dimensional reconstruction imaging models, and to use this method for estimating an average knee valgus angle value for northern Chinese adults. Computed tomographic angiography data in DICOM format for 128 normal femurs(More)
OBJECTIVE To investigate the protective effect of antler polypeptide on the rats with spinal cord injury (SCI). METHODS The model rats were treated with different doses of antler polypeptide, and its effect on motor function, ethology and pathological changes of spinal cord of the rats observed. RESULTS Seven days after treatment with different doses of(More)
