Fatigue in the Superficial and Deep Digital Flexor Muscles During Exercise in Thoroughbred Horses

T Takahashi, H Ohmura, K Mukai, A Matsui, more

Equine Veterinary Journal > 46 > S46 > 30 - 30

IntroductionOne of the causes of injury to the superficial digital flexor tendon (SDFT) is assumed to be repeated high intensity loading of the tendon. Earlier fatigue of the deep digital flexor muscle (DDFM) in comparison to the time of fatigue of the superficial digital flexor muscle (SDFM) is also assumed to increase load on the SDFT during long distance running. This study evaluated the fatigue...

Octacalcium phosphate collagen composites with titanium mesh facilitate alveolar augmentation in canine mandibular bone defects

K. Miura, K. Matsui, T. Kawai, Y. Kato, more

International Journal of Oral & Maxillofacial Surgery > 2012 > 41 > 9 > 1161-1169

This study was designed to investigate whether bone regeneration by implantation of octacalcium phosphate and porcine atelocollagen composite (OCP/Col) would be enhanced if mechanical stress to the implanted OCP/Col were alleviated. OCP/Col discs were implanted into an arc-shaped mandibular defect in male adult beagle dogs divided into untreated, OCP/Col, and OCP/Col/Mesh groups. In the OCP/Col/Mesh...

Predicting the survival of experimental ischaemic small bowel using intraoperative near‐infrared fluorescence angiography

A. Matsui, J. H. Winer, R. G. Laurence, J. V. Frangioni

British Journal of Surgery > 98 > 12 > 1725 - 1734

Background:Predicting the long‐term viability of ischaemic bowel during surgery is challenging. The aim was to determine whether intraoperative near‐infrared angiography (NIR‐AG) of ischaemic bowel might provide metrics that were predictive of long‐term outcome. Methods:NIR‐AG using indocyanine green was performed on 24 pigs before, and after inducing bowel ischaemia to determine the feasibility...

Prototyping eco power generator using giant magnetostriction material

A Matsui, Y Yamamoto, Y Matsui

2011 Fourth International Conference on Modeling, Simulation and Applied Optimization > 1 - 5

2011 Fourth International Conference on Modeling, Simulation and Applied Optimization (ICMSAO 2011)

Since giant magnetostriction was first found at aroom temperature in early 1980s, there have been many applications proposed. This paper introduces a novel application which is able to generate electric power by utilizing a reverse transduction of the material called Villari effect. The generator uses vibration as a power source which is easily accessible in our daily life such as traffic-induced...

Bone regeneration by octacalcium phosphate collagen composites in a dog alveolar cleft model

K. Matsui, A. Matsui, T. Handa, T. Kawai, more

International Journal of Oral & Maxillofacial Surgery > 2010 > 39 > 12 > 1218-1225

Octacalcium phosphate (OCP) and porcine atelocollagen sponge composites (OCP/Col) markedly enhanced bone regeneration in a rat cranial defect model. To assess clinical application, the authors examined whether OCP/Col would enhance bone regeneration in an alveolar cleft model in an adult dog, which was assumed to reflect patients with alveolar cleft. Disks of OCP/Col or collagen were implanted into...

Fence Removal from Multi-focus Images

A Yamashita, A Matsui, T Kaneko

2010 20th International Conference on Pattern Recognition > 4532 - 4535

2010 20th International Conference on Pattern Recognition (ICPR 2010)

When an image of a scene is captured by a camera through a fence, a blurred fence image interrupts objects in the scene. In this paper, we propose a method for a fence removal from the image using multiple focusing. Most of previous methods interpolate the interrupted regions by using information of surrounding textures. However, these methods fail when information of surrounding textures is not rich...

Experimental demonstration of high-resolution ultra-wideband impulse radar based on electrical-optical hybrid pulse generation

M Hanawa, K Mori, K Nakamura, A Matsui, more

IET Microwaves, Antennas & Propagation > 2010 > 4 > 10 > 1562 - 1468

A high-resolution ultra-wideband (UWB) impulse radar has been developed in order to realise high-resolution object imaging in a ground-penetrating radar (GPR) for landmine detection. The UWB impulse radar is based on an electrical-optical hybrid pulse generation scheme such that a clean, short pulse train with small, short ringing can be generated. The generated UWB impulse train has a pulse duration...

Nuclear capture at rest of Ξ− hyperons

S. Aoki, S.Y. Bahk, S.H. Chung, H. Funahashi, more

Nuclear Physics, Section A > 2009 > 828 > 3-4 > 191-232

An emulsion-counter hybrid experiment (KEK E176) was carried out to search for double strangeness systems such as double-Λ hypernuclei and H-dibaryons. More than 10% of Ξ− hyperons produced in the (K ⁻ , K ⁺ ) reaction were brought to rest in the nuclear emulsion. We have obtained 98 candidate events of nuclear capture at rest of Ξ− hyperons which are described in this report. Among...

An experimental investigation of FCC-compliant UWB-IR pulse radar

K. Mori, M. Hanawa, K. Nakamura, A. Matsui, more

2008 Asia-Pacific Microwave Conference > 1 - 4

2008 Asia Pacific Microwave Conference

The FCC-compliant UWB-IR pulse radar was reported. Thanks to the ultra short pulses, which have a lOdB bandwidth of 7.23GHz, the investigated UWB-IR pulse radar was able to resolve the relative positional change of the target for reflection with a high spatial resolution less than 10 mm, resulting in the collect identification of the complex shaped target. Improvement of the migration process by considering...

2008 19th International Conference on Pattern Recognition > 1 - 4

ICPR 2008 19th International Conference on Pattern Recognition

This paper proposes a probabilistic search algorithm to boost the computational efficiency of face detection in video sequences. The algorithm sequentially predicts the probability distributions of face region parameters in the current video frame given a sequence of past frames, and automatically re initializes the prediction process at scene changes in the given video sequence. A Bayesian criterion...

2008 International Symposium on Micro-NanoMechatronics and Human Science > 475 - 480

2008 International Symposium on Micro-NanoMechatronics and Human Science

The present study was designed to investigate whether compressive mechanical strain affects osteoblastic cell differentiation. We developed a culture system with the multi channel that induces the mechanical stimuli with quantitative gradient strain on seeded cells during the culture. This culture system was a computer-driven device that the various mode of mechanical strains can be applied, using...

2008 IEEE Antennas and Propagation Society International Symposium and USNC/URSI National Radio Science Meeting

This paper has proposed BPTSA and discussed the some characteristics. It has been revealed that BPTSA has shown little differences in the matching, radiation and pulse response to conventional TSA within the interested band. Therefore, the design charge of components in UWB-IR, especially filter, has been able to be reduced without degradation of whole system performance. Detail discussion for pulse...

2008 IEEE Antennas and Propagation Society International Symposium > 1 - 4

2008 IEEE Antennas and Propagation Society International Symposium and USNC/URSI National Radio Science Meeting

This report has discussed the radiation characteristics of CDLA. It has been revealed that the bandwidth and gain of CDLA composed of one wavelength loop and matching section has depend on its feeding position. The input impedance set to 200Omega has displayed the wide band characteristic and the impedance set to 50Omega has shown comparably high gain in spite of narrow bandwidth. The design method...

Transplantation Proceedings > 2008 > 40 > 2 > 574-577

We directly injected porcine donor mesenchymal stem cells (MSC) into murine bone marrow (BM) cavities to examine the effects of intra-BM cotransplantation of MSC in pig-to–NOD/SCID mouse bone marrow transplantation (BMT) on xenogeneic engraftment. Porcine MSC prepared by aspiration of iliac BM of miniature swine were identified as CD90+CD29+CD45−CD31- and shown to differentiate into osteoblastocytes...

This report has described the radiation and matching characteristic of MTSA in some mesh shape. It has been shown from experiment that the mesh shape has influenced to the matching in the high frequency range and the radiation pattern and the gain in the low frequency range. MTSA has possibility that the radiation pattern is able to be controlled by the mesh configuration. It also deals with consideration...
