PURPOSE Our previous results for treatment of hepatocellular carcinoma with proton beam therapy (PBT) revealed excellent local control. In this study, we focused on the impact of PBT on normal liver function. METHODS AND MATERIALS The subjects were 259 patients treated with PBT at the University of Tsukuba between January 2001 and December 2007. We(More)
Although thousands of long noncoding RNAs (lncRNAs) are localized in the nucleus, only a few dozen have been functionally characterized. Here we show that nuclear enriched abundant transcript 1 (NEAT1), an essential lncRNA for the formation of nuclear body paraspeckles, is induced by influenza virus and herpes simplex virus infection as well as by Toll-like(More)
BACKGROUND Previous comparative reports of stereotactic body radiotherapy (SBRT) and surgery for non-small cell lung cancer (NSCLC) suffered from short follow-up, mixed extents of resection and inclusion of benign lesion. We aimed to make comparisons of long-term outcomes between a pure series of video-assisted thoracoscopic surgery (VATS) lobectomy and(More)
We report a case of an 80-year-old woman with dropped head syndrome associated with cervical spondylotic myelopathy. She could not keep her cervical spine in a neutral position for >1 minute. She had a disturbed gait and severe kyphotic deformity in her thoracic spine. Magnetic resonance imaging revealed severe compression of the spinal cord due to cervical(More)
Magnetic resonance imaging (MRI) data is an invaluable tool in brain morphology research. Here, we propose a novel statistical method for investigating the relationship between clinical characteristics and brain morphology based on three-dimensional MRI data via radial basis function-sparse partial least squares (RBF-sPLS). Our data consisted of MRI image(More)
Influenza A virus is a major human and animal pathogen with the potential to cause catastrophic loss of life. The virus reproduces rapidly, mutates frequently and occasionally crosses species barriers. The recent emergence in Asia of avian influenza related to highly pathogenic forms of the human virus has highlighted the urgent need for new effective(More)
PURPOSE Programmed death-1 (PD-1), a coinhibitory immune signal receptor expressed in T cells, binds to PD-1 ligand and regulates antitumor immunity. Nivolumab is an anti-PD-1 antibody that blocks PD-1 signaling. We assessed the safety and antitumor activity of nivolumab in patients with platinum-resistant ovarian cancer. PATIENTS AND METHODS Twenty(More)
Transcription and replication of the influenza virus RNA genome occur in the nuclei of infected cells through the viral RNA-dependent RNA polymerase consisting of PB1, PB2, and PA. We previously identified a host factor designated RAF-1 (RNA polymerase activating factor 1) that stimulates viral RNA synthesis. RAF-1 is found to be identical to Hsp90. Here,(More)
By dissecting and reconstituting a cell-free influenza virus genome replication system, we have purified and identified the minichromosome maintenance (MCM) complex, which is thought to be a DNA replicative helicase, as one of the host factors that regulate the virus genome replication. MCM interacted with the PA subunit of the viral RNA-dependent RNA(More)
BACKGROUND The aim of this study was to perform a survival comparison between stereotactic body radiotherapy (SBRT) and sublobar resection (SLR) in patients with stage I non-small-cell lung cancer (NSCLC) at high risk for lobectomy. METHODS All patients who underwent SBRT or SLR because of medical comorbidities for clinical stage I NSCLC were reviewed(More)
