Sonographic Detection of Subcutaneous Foreign Bodies in 3 Cases

Subcutaneous masses caused by foreign bodies are frequently encountered in daily practice. Although the majority of foreign bodies such as metals can be detected by radiography, substances such as vegetative materials or wood are difficult to detect. To our knowledge, only a few studies have described the sonographic characteristics of foreign bodies. Herein, we report 3 cases where we studied the sonographic characteristics of the foreign bodies in the dermis and subcutaneous tissue. Our results revealed the following 3 foreign bodies: (1) glass, (2) vegetative material, and (3) a pencil core. Thus, sonographic examination is useful for the detection of foreign bodies

Results of the first sea-test of Tsukuyomi: A prototype of underwater gliders for virtual mooring

This paper presents the results of the first sea-test of Tsukuyomi - a prototype of underwater gliders for virtual mooring. Its will be able to stay in a designated water for more than one year, reciprocating between the sea-surface and the seafloor up to 3,000 meters in depth. It will sleep on the seafloor to elongate the operation time. We have successfully conducted tank-test in December 2011 and the first sea-test in March 2012. Although for the sake of safety, a thin string was connected to Tsukuyomi in the first sea-test, the dynamic stability, the maneuverability and the basic function of Tsukuyomi were confirmed.Date of Conference: 14-19 October 2012http://www.godac.jamstec.go.jp/darwin/cruise/kaiyo/ky12-04/

Histological and Nuclear Medical Comparison of Inflammation After Hemostasis with Non-Thermal Plasma and Thermal Coagulation

The objective of this study is to examine the invasiveness of hemostasis by non-thermal plasma (NTP) compared with hemostasis by thermal coagulation (TC). The inflammation recovery process after hemostasis by TC and NTP was compared by using histological methods and nuclear medical molecular imaging. The necrotic areas in the NTP group disappeared after 5 days, whereas they remained 15 days after hemostasis in the TC group. The accumulation of 2-deoxy-2-[F-18] fluoro-D-glucopyranose (F-18-FDG), which reflects the existence of inflammatory cells, was higher in the TC group than in the NTP group on day 15. Thus, this study indicates that hemostasis by NTP is less inflammatory than TC. This report is the first to evaluate inflammation that occurred after hemostasis with medical devices noninvasively

Effects of Initial Graft Tension during Anterior Talofibular Ligament Reconstruction on Ankle Kinematics, Laxity, and In-situ Forces of the Reconstructed Graft

前距腓靭帯は，足関節の安定性に関わる重要な靱帯である．前距腓靱帯の損傷後に慢性的な足関節の不安定性が残存した場合，前距腓靱帯再建手術が必要となるが，その際に再建靭帯にかける適切な張力について研究した報告はなかった．本論文では，再建靭帯にかける張力の違いが，足関節のキネマティクス，制動性，術後の靱帯張力に及ぼす影響と適切な再建靭帯初期固定張力を明らかにした

Prognostic Impact of Hypoxia-Inducible miRNA-210

Objective. The aim of this study was to investigate the prognostic value of MicroRNA-210 (miR-210) expression in patients with non-small-cell lung cancer (NSCLC). Methods. We examined the miR-210 expression of samples of 80 patients, who underwent surgical resection at Fukushima Medical University from 2004 to 2007, by using quantitative RT-PCR. The relationship between miR-210 expression and clinicopathological factors as well as histological subtype was statistically analyzed. Results. miR-210 expression showed an inverse correlation with disease-free and overall survival in patients with NSCLC. Significant correlations were found between miR-210 expression and lymph node metastasis, late disease stages, and poor prognosis in patients with adenocarcinoma. Multivariate Cox analysis indicated that miR-210 expression was an independent prognostic factor for disease-free survival in patients with adenocarcinoma. Conclusions. We showed that miR-210 may be a prognostic biomarker for patients with NSCLC, especially for those with lung adenocarcinoma

The ASTRO-H X-ray Observatory

The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will investigate the physics of the high-energy universe via a suite of four instruments, covering a very wide energy range, from 0.3 keV to 600 keV. These instruments include a high-resolution, high-throughput spectrometer sensitive over 0.3-2 keV with high spectral resolution of Delta E < 7 eV, enabled by a micro-calorimeter array located in the focal plane of thin-foil X-ray optics; hard X-ray imaging spectrometers covering 5-80 keV, located in the focal plane of multilayer-coated, focusing hard X-ray mirrors; a wide-field imaging spectrometer sensitive over 0.4-12 keV, with an X-ray CCD camera in the focal plane of a soft X-ray telescope; and a non-focusing Compton-camera type soft gamma-ray detector, sensitive in the 40-600 keV band. The simultaneous broad bandpass, coupled with high spectral resolution, will enable the pursuit of a wide variety of important science themes.Comment: 22 pages, 17 figures, Proceedings of the SPIE Astronomical Instrumentation "Space Telescopes and Instrumentation 2012: Ultraviolet to Gamma Ray
