4 A rare case of adult medullomyoblastoma with unique location presented. The patient was admitted to our clinic with the history of progressive balance disorder, nausea and vomiting. Disequilibrium had started 2 months earlier. The patient underwent a craniotomy and histopathologic examination revealed a biphasic tumor. Few definite strap cells with striation were identified in the tumor. The ...

We derive an exact deterministic nonlinear observer to compute the continuous state of an inertial navigation system based on partial discrete measurements, the so-called strap-down problem. Nonlinear contraction is used as the main analysis tool, and the hierarchical structure of the system physics is systematically exploited. The paper also discusses the use of nonlinear measurements, such as...

Proton beam irradiation is a form of advanced radiotherapy providing superior distributions of a low LET radiation dose relative to that of photon therapy for the treatment of cancer. Even though this clinical treatment has been developing for several decades, the proton radiobiology critical to the optimization of proton radiotherapy is far from being understood. Proteomic changes were analyze...

OBJECTIVES Postoperative hemorrhage is a potentially life-threatening complication in thyroid surgery. This study was performed to review the clinical patterns of post-thyroidectomy hemorrhage, and especially as they are related to the source of bleeding. METHODS We performed a retrospective review of 10 patients (0.96%) with post-thyroidectomy hemorrhage that required surgical evacuation. Th...

Assistive and rehabilitative powered exoskeletons for spinal cord injury (SCI) and stroke subjects have recently reached the clinic. Proper tension and joint alignment are critical to ensuring safety. Challenges still exist in adjustment and fitting, with most current systems depending on personnel experience for appropriate individual fastening. Paraplegia and tetraplegia patients using these ...

In the current study, the failure behavior of retrofitted steel structures was studied experimentally and theoretically with steel/CFRP double strap joints (DSJs) under quasi-static tensile loading. A series of DSJs with different bonding lengths are also considered and examined to experimentally assess the effective bond length. To predict the failure load values of the tested specimens, a new...

The NXF (nuclear export factor) family members are implicated in the transport of mRNA from the nucleus to the cytoplasm. Recently, some members of the NXF family have been reported to play divergent functional roles, such as post-transcriptional regulation, translational control, regulation of mRNA stability and trafficking. However, little is known about the roles of NXF3 in spermatogenesis. ...
