STUDY DESIGN A new surgical strategy for treatment of patients with spinal metastases was designed, and 61 patients were treated based on this strategy. OBJECTIVES To propose a new surgical strategy for the treatment of patients with spinal metastases. SUMMARY OF BACKGROUND DATA A preoperative score composed of six parameters has been proposed by(More)
The serine/threonine kinase Akt (also called protein kinase B) is well known as an important regulator of cell survival and growth and has also been shown to be required for cell migration in different organisms. However, the mechanism by which Akt functions to promote cell migration is not understood. Here, we identify an Akt substrate, designated(More)
STUDY DESIGN Matched patient cohorts using retrospective chart and radiographic review with independent clinical and radiographic follow-up were reviewed. OBJECTIVE To compare the clinical and radiographic outcomes of multilevel corpectomy and laminoplasty using an independent matched-cohort analysis. SUMMARY OF BACKGROUND DATA The treatment of choice(More)
The objective was to characterize imaging findings of benign notochordal cell tumors (BNCTs). Clinical and imaging data for 9 benign notochordal cell tumors in 7 patients were reviewed retrospectively. Conventional radiographs (n = 9), bone scintigrams (n = 2), computed tomographic images (n = 7), and magnetic resonance images (n = 8) were reviewed. Eight(More)
Germ-line point mutations of the RET gene are responsible for multiple endocrine neoplasia (MEN) type 2A and 2B that develop medullary thyroid carcinoma and pheochromocytoma. We performed a differential display analysis of gene expression using NIH 3T3 cells expressing the RET-MEN2A or RET-MEN2B mutant proteins. As a consequence, we identified 10 genes(More)
STUDY DESIGN A retrospective review (phase 1) and prospective clinical study (phase 2). OBJECTIVES To identify independent risk factors for surgical site infection (SSI) and to evaluate the positive effect of prostaglandin E1 (PGE1) to decrease the risk of SSI in patients with spinal metastasis. SUMMARY OF BACKGROUND DATA Surgery for spinal metastasis(More)
Several studies have shown the relation between Graves’ disease and stenosis/occlusion of intracranial arteries. To our knowledge, only 31 cases, including our case, of concurrent Graves’ disease and moyamoya syndrome or intracranial arterial stenosis/occlusion have been described. The patients were predominantly women, and their ages ranged from 10 to 54(More)
INTRODUCTION Mesenchymal status is related to "inherent resistance" to gefitinib or erlotinib in non-small cell lung cancer without epidermal growth factor receptor(EGFR) mutations. In addition, a recent report showed that the epithelial to mesenchymal transition (EMT) plays a role in acquired resistance to gefitinib in A549 cells, which harbor a KRAS(More)
The proneural basic-helix-loop-helix protein achaete-scute homologue 1 (ASH1) is expressed in a very limited spectrum of normal and cancerous cells in a lineage-specific manner, including normal pulmonary neuroendocrine cells and lung cancer cells with neuroendocrine features. Our previous results indicated that ASH1 may play a crucial role in the growth(More)
Hepatocellular carcinoma (HCC) most commonly arises from chronic inflammation due to viral infection, as a result of genetic and epigenetic abnormalities. A global picture of epigenetic changes in HCC is lacking. We used methylated CpG island amplification microarrays (MCAMs) to study 6458 CpG islands in HCC and adjacent preneoplastic tissues [chronic(More)
