Eukaryotic cells express several classes of small RNAs that regulate gene expression and ensure genome maintenance. Endogenous siRNAs (endo-siRNAs) and Piwi-interacting RNAs (piRNAs) mainly control gene and transposon expression in the germline, while microRNAs (miRNAs) generally function in post-transcriptional gene silencing in both somatic and germline(More)
Staphylococcus aureus is the leading cause of wound and hospital-acquired infections worldwide. The emergence of S. aureus strains with resistance to multiple antibiotics requires the identification of bacterial virulence genes and the development of novel therapeutic strategies. Herein, bursa aurealis, a mariner-based transposon, was used for random(More)
BACKGROUND Clusters of acute flaccid paralysis or cranial nerve dysfunction in children are uncommon. We aimed to assess a cluster of children with acute flaccid paralysis and cranial nerve dysfunction geographically and temporally associated with an outbreak of enterovirus-D68 respiratory disease. METHODS We defined a case of neurological disease as any(More)
Radiofrequency ablation (RFA) and vertebral augmentation is an emerging combination therapy for painful osseous metastases that cannot be or are incompletely palliated with radiation therapy. Herein, we report our experience performing RFA and vertebral augmentation of spinal metastases for pain palliation. Institutional review board approval was obtained(More)
BACKGROUND AND PURPOSE Combination radiofrequency ablation and vertebral augmentation is an emerging minimally invasive therapy for patients with metastatic spine disease who have not responded to or have contraindications to radiation therapy. The purpose of this study was to evaluate the rate of radiographic local control of spinal metastases treated with(More)
BACKGROUND Over years, surgical training is changing and years of tradition are being challenged by legal and ethical concerns for patient safety, work hour restrictions, and the cost of operating room time. Surgical simulation and skill training offer an opportunity to teach and practice advanced techniques before attempting them on patients. Simulation(More)
BACKGROUND AND PURPOSE Percutaneous cryoablation has emerged as a minimally invasive technique for the management of osseous metastases. The purpose of this study was to assess the safety and effectiveness of percutaneous imaging-guided spine cryoablation for pain palliation and local tumor control for vertebral metastases. MATERIALS AND METHODS(More)
BACKGROUND Radiation therapy (RT) is the current gold standard for palliation of painful vertebral metastases. However, other percutaneous modalities such as radiofrequency ablation (RFA), cryoablation, and vertebral augmentation have also been shown to be effective in alleviating symptoms. Combined RT and ablation may be more effective than either therapy(More)
Cerebrospinal fluid shunts are primarily used for the treatment of hydrocephalus. Shunt complications may necessitate multiple non-contrast head CT scans resulting in potentially high levels of radiation dose starting at an early age. A new head CT protocol using automatic exposure control and automated tube potential selection has been implemented at our(More)
Neurotrophin receptors of the Trk family play a vital role in the survival of developing neurons and the process of axonogenesis. The Trk family are receptor protein tyrosine kinases (RTKs) and their signalling in response to neurotrophins is critically dependent upon their ability to transphosphorylate and act as signalling centres for multiple adaptor(More)
