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)
surgical techniques. A review of the developmental process of this operation leads to recognition of the tips, pitfalls, and solutions. We review here the principal concepts of TES for spinal tumors, as well as their related basic works that support the rationality of this operation. 1. Oncologic concept of spinal tumors (compartment and barriers) Enneking(More)
Iron overload has been associated with carcinogenesis in humans. Intraperitoneal administration of ferric nitrilotriacetate initiates a Fenton reaction in renal proximal tubules of rodents that ultimately leads to a high incidence of renal cell carcinoma (RCC) after repeated treatments. We performed high-resolution microarray comparative genomic(More)
A biomechanical study of an interspinous stabilization spinal implant (Coflex) was carried out using eight human lumbar L4/L5 motion segments. Each motion segment was tested in compression, then flexion/extension, then lateral bending, and then axial rotation at five conditions: 1) intact; 2) partial destabilization (by cutting the supraspinous and(More)
BACKGROUND Postoperative infection associated with implants remains a serious complication in orthopedic surgery. Several biomaterial surface treatments have been proposed as a means of reducing the incidence of implant-associated infections. In this study, a clinical trial was performed using an iodine-supported titanium that suppresses the microbial(More)
Microtubule-associated protein MAP1A is expressed abundantly in mature neurons and is necessary for maintenance of neuronal morphology and localization of some molecules in association with the microtubule-based cytoskeleton. Previous studies indicated that its complementary expression together with MAP1B during nervous system development is regulated at(More)
BACKGROUND Total en bloc spondylectomy (TES) is a surgery designed to achieve complete resection of a malignant spinal tumor such as spinal metastasis. Although this procedure decreases the rate of local recurrence, it is questionable whether local control prolongs patient's survival. We developed a "second-generation TES" that brings about TES enhancing(More)
Malignant mesothelioma (MM) is an incurable malignancy that is caused by exposure to asbestos and is accompanied by severe fibrosis. Because MM is usually diagnosed at an advanced stage and clinical identification of early lesions is difficult, its molecular pathogenesis has not been completely elucidated. Nearly 75% of MM cases have inactivating mutations(More)
Mycobacterium abscessus infections rarely develop in healthy individuals, and mostly they occur in immunocompromised hosts. Vertebral osteomyelitis due to Mycobacterium abscessus is very rare and only three previous cases of spinal infection caused by Mycobacterium abscessus have been reported. Mycobacterium abscessus isolates are uniformly resistant to(More)
Tissue engineering and cell therapies are currently being leveraged to find improved treatment strategies in orthopaedics. Adipose stem cells have been considered for their potential to differentiate into different cell lineages. The potential of adipose stem cells to restore chondral, bone and tendon tissue has been demonstrated in vivo and in vitro(More)
