Didactic surgical experience of thyroid metastasis from renal cell carcinoma: A case report

World Journal of Clinical Cases 2018年第15期6卷 1018-1023页

作者： Moriyasu Yamauchi Keita Kai Natsuko Shibamiya Rintaro Shimazu Mikio Monji Kumiko suzuki Hiroaki Kakinoki Shohei Tobu yuichiro Kuratomi Department of Otolaryngology Head and Neck Surgery Saga University Faculty of Medicine Department of Pathology Saga University Hospital Department of Urology Saga University Faculty of Medicine

BACKGROUND The optimal therapeutic strategy in treating thyroid metastasis from renal cell carcinoma(RCC) has not been clearly established. Here we describe a case of didactic surgical experience of the disease which caused massive intraoperative *** SUMMARY A 59-year-old male patient presented with a thyroid left lobe soft mass detected by chest computed tomography scans prior to the surgical treatment of RCC of the left kidney. The thyroid mass was initially considered to be benign, then he underwent left radical nephrectomy. One year after the nephrectomy, stereotactic radiosurgery was performed for brain metastasis. During follow-up, the thyroid nodule gradually grew, and the patient manifested swallowing discomfort. Under a clinical diagnosis of thyroid follicular neoplasm, left hemithyroidectomy was performed. Although hemithyroidectomy is usually a safe and straightforward procedure, massive bleeding from markedly developed tumor vessels made the operation very difficult. The thyroid tumor was finally diagnosed as metastasis from clear cell RCC. CONCLUSION For proper timing of the surgery, a clinician should take into consideration the possibility of thyroid metastasis of RCC when a thyroid lesion is found in patients with RCC or in patients with a previous history of RCC. We recommend that thyroid metastasis of RCC should be resected as early as possible even if a patient has other metastatic sites.

Femtosecond pulses cleaning by transient-grating process in Kerr-optical media

引用

Chinese Optics Letters 2011年第5期9卷 63-65页

作者： Kotaro Okamura yuichiro Kida Takayoshi Kobayashi Advanced Ultrafast Laser Research Center and Department of Engineering ScienceFaculty of Informatics and EngineeringDepartment of Engineering ScienceThe University of Electro-Communications International Cooperative Research Project (ICORP) Japan Science and Technology Agency Department of Electrophysics National Chiao Tung University Institute of Laser Engineering Osaka University

We use a transient-grating （TG） process in a Kerr bulk medium to clean a femtosecond laser pulse. Using the technique, the temporal contrast of the generated TG signal is improved by more than two orders of magnitude in comparison with the incident pulse in a 0.5-mm-thick fused silica plate. The laser spectrum is smoothed and broadened, and the pulse duration is shortened simultaneously. We expect to extend this technique to a clean pulse with broadband spectral bandwidth at a wide spectral range because it is a phase-matched process.

Investigation of Surge Behavior in a Micro Centrifugal Compressor

Journal of Thermal Science 2006年第2期15卷 97-102页

作者： Shimpei MIZUKI yuichiro ASAGA Yushi ONO Hoshio TSUJITA Department of Mechanical Engineering Hosei University 3-7-2Kajino-choKoganei-shiTokyo Mitsubishi Heavy Industries Ltd. 1-1 Akunoura-machi Nagasaki-shi Nagasaki Department of Mechanical Engineering Hosei University 3-7-2 Kajino-cho Koganei-shi Tokyo

This paper reports the experimental and theoretical study of the surge occurred in prototyping an ultra micro centrifugal compressor. As the first step, the 10 times size model of an ultra micro centrifugal compressor having the 40 mm outer diameter was designed and manufactured. The detailed experimental investigations for the transient behavior of surge with several different values of B parameter were carded out. The experimental results during the surge were compared with those obtained by the non-linear lumped parameter theory in order to validate the effectiveness of the theoretical surge model for the micro centrifugal compressor. As a result, the quite different behavior of the surge appeared for the different values of B both in the experiment and in the analysis.

Surge Control of a Centrifugal Compression System by Using a Bouncing Ball

引用

Journal of Thermal Science 2008年第2期17卷 141-146页

作者： yuichiro Asaga Shimpei Mizuki Hoshio Tsujita Shinsuke Ohta Department of Mechanical Engineering Faculty of EngineeringHosei University Mitsubishi Heavy Industries Ltd.

The purpose of this study is to suppress the fluctuations of surge by a simple passive control method. A bouncing ball system with different weight of the balls was tested. As a result, the bouncing ball system suppressed mild surge without the deterioration of the performance characteristics, and moved the initiation point of surge toward the lower flow rate when the steel ball of 15mm outer diameter was used. The present system was effective to suppress the surge and to widen the stable operating range of a centrifugal compressor when the ball was chosen appropriately.
