In mobile wireless networks, the emerging proximity-based applications have led to needs for highly effective and energy-efficient neighbor discovery protocols. However, existing works cannot realize the optimal worst-case latency in symmetric case, and their performances with asymmetric duty cycles can still be improved. In this work, we investigate(More)
Besides the MHC gene, HLA-B27, ERAP1 is one of the non-MHC genes which also play key roles in the pathogenesis of AS. It has been reported that there is an association between ERAP1 polymorphisms and AS Risk. However, the results were inconclusive. The aim of the current study was to determine the contribution of ERAP1 polymorphisms to ankylosing(More)
In the problem of routing in multi-hop wireless networks, to achieve high end-to-end throughput, it is crucial to find the “best” path from the source node to the destination node. Although a large number of routing protocols have been proposed to find the path with minimum total transmission count/time for delivering a single packet, such transmission(More)
Aggressive giant cell tumor (GCT) is an important subtype of GCT and is relatively rare in the spine. There is little published information regarding this subject. The objective of our study is to discuss prognostic factors for primary aggressive GCT in the spine. A retrospective study of patients who had primary aggressive GCT in the spine and underwent(More)
BACKGROUND Chordoma in the spine is relatively rare, and minimal information has been published in the literature regarding this subject. Moreover, there are controversies over prognostic factors of this disease. METHODS A retrospective analysis of chordoma in the spine was performed by survival analysis. Local relapse-free survival (LRFS) and overall(More)
RunX2 has been identified to crucially regulate the osteolysis in giant cell tumor of bone. MiR-30a is an intronic miRNA identified as tumor suppressor, but little is known about its role in giant tumor cell of bone. In our research, we reported miR-30a was down-regulated in GCT whereas RunX2 was highly expressed. Further research proved that miR-30a can(More)
INTRODUCTION Accurate prediction of the biochemical recurrence (BCR) is critical for patients after intended curative therapy like radical prostatectomy (RP) or definitive radiotherapy for prostate cancer. Glutathione-S-transferases polymorphisms as well as hypermethylation of GSTP1 and functional genes in carcinogenesis, including tumor suppression gene(More)
BACKGROUND Tumor-induced osteomalacia (TIO) is a rare disorder, which is commonly found in craniofacial locations and in the extremities. To the best of our knowledge, only 16 cases have been described in the spine, and this is the first report to describe a case of patient with TIO in the thoracic spine combined with a mesenchymal hamartoma which had(More)
