Estrogen-related receptor alpha promotes thyroid tumor cell survival via a tumor subtype-specific regulation of target gene networks.

Mortalin (encoded by HSPA9) is a mitochondrial chaperone often overexpressed in cancer through as-yet-unknown mechanisms. By searching different RNA-sequencing datasets, we found that ESRRA is a transcription factor highly correlated with HSPA9 in thyroid cancer, especially in follicular, but not C cell-originated, tumors. Consistent with this correlation, ESRRA depletion decreased mortalin expression only in follicular thyroid tumor cells.

Comparison between Onyx and coil embolization for persistent type 2 endoleaks after endovascular aneurysm repair.

Purpose: Type 2 endoleaks (T2EL) are the most common form of endoleaks after endovascular aneurysm repair (EVAR). Several studies on the feasibility of embolization using ethylene vinyl alcohol copolymer (Onyx, Medtronic) for T2EL have been reported. The purpose of this study was to compare coil and Onyx embolization for T2EL treatment after EVAR.

A review of robotic-assisted total hip arthroplasty.

Total hip arthroplasty (THA) is a successful surgical method for hip replacement but still poses challenges and risks. Robotic-assisted THA (rTHA) using new generation robotic systems has emerged to improve surgical precision and outcomes. The purpose of this paper is to review the literature on rTHA, with a focus on its advantages, such as individualized preoperative planning, intraoperative assistance, and improved accuracy in implantation, especially in complex cases.

How to Perform Concomitant Medial Meniscus Pull-Out Repair With Medial Open-Wedge High Tibial Osteotomy Without Technical Failure.

Varus alignment of the knee joint (varus >5°) is known as a poor prognostic factor for medial meniscus root repair, and alignment correction is recommended in patients with varus deformity and medial meniscus root tears. However, simultaneous medial meniscus pull-out repair and high tibial osteotomy are technically demanding procedures due to the long surgical time, poor visualization, and breaking of the pull-out sutures during high tibial osteotomy procedures. In the present Technical Note, we will introduce a surgical method to perform 2 procedures simultaneously without technical difficulty.

Alterations of Functional Connectivity in Patients With Restless Legs Syndrome.

Restless legs syndrome (RLS) is a common neurological illness marked by a strong desire to move one's legs, usually in association with uncomfortable sensations. Recent studies have investigated brain networks and connectivity in RLS. The advent of network analysis has greatly improved our understanding of the brain and various neurological disorders.

A novel vertebroplasty technique using a larger-diameter needle for thoracolumbar osteoporotic vertebral compression fracture.

Percutaneous vertebroplasty (VP) and kyphoplasty (KP) are well-established minimally invasive surgical procedures for the treatment of osteoporotic vertebral compression fractures (OVCF). However, some drawbacks have been reported regarding these procedures, including height loss, cement leakage, and loss of the restored height after balloon deflation. We performed a novel VP technique to minimize these limitations of conventional procedures.
