STUDY DESIGN Literature review and meta-analysis. OBJECTIVE To perform a systematic review and meta-analysis of risk factors for new osteoporotic vertebral compression fracture (VCF) after vertebroplasty. SUMMARY OF BACKGROUND DATA New osteoporotic VCF is one of the serious complications of vertebroplasty, and it is important to investigate the risk(More)
STUDY DESIGN Technical note. OBJECTIVE To determine the correlation between the high-intensity lesions observed on T2-weighted magnetic resonance images (T2W MRI) and the cervical dynamic characteristics of patients with cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA Intramedullary high signal intensity is frequently observed on T2W(More)
The thermo-mechanical controlled process (TMCP) of 800-MPa-grade non-quenched tempered steel used for penstocks was simulated on a Gleeble-3500 thermo-mechanical simulator. The effect of the finish cooling temperature (FCT) which ranged from 350–550 ◦C on the microstructure and mechanical properties was studied. The microstructure of TMCP specimens is(More)
mTOR is a valuable oncotarget for osteosarcoma. The anti-osteosarcoma activity by a novel mTOR kinase inhibitor, CZ415, was evaluated. We demonstrated that CZ415 potently inhibited survival and proliferation of known osteosarcoma cell lines (U2OS, MG-63 and SaOs2), and primary human osteosarcoma cells. Further, CZ415 provoked apoptosis and disrupted cell(More)
This paper introduces the TCN MVB (Multifunction Vehicle Bus) communication mechanism and characteristics. On this basis, a method of VHDL language is designed for the core part of MVBC (MVB bus controller), such as the Manchester encoding and decoding, CRC check functions, etc. Among them, the bus’s CRC checksum data is formed with a double check(More)
Osteoporosis is a common problem in aged people and those with related diseases, such as inflammatory bowel diseases. Deregulation of vitamin D metabolism plays a role in the pathogenesis of osteoporosis. Micro RNA (miR) can regulate cytokine expression in cells. This study test a hypothesis that inflammatory cytokine interleukin (IL)-13 increases miR-19a(More)
