Laser-Compton scattering (LCS) x-ray sources have recently attracted much attention for their potential use at local medical facilities because they can produce ultrashort pulsed, high-brilliance, and quasimonochromatic hard x rays with a small source size. The feasibility of in-line phase-contrast imaging “thick” biological specimens rat lumbar vertebrae using the developed compact LCS-X in AIST was investigated promotion clinical imaging. In higher-quality images, anatomical details...
PURPOSE: To classify the veins of Retzius demonstrated at computed tomography (CT) during arterial portography (CTAP) on basis anatomic location and to evaluate relationship between frequency CT visualization associated disease. MATERIALS AND METHODS: The authors reviewed axial CTAP scans from 130 patients. Patients were classified into one two groups: patients with liver cirrhosis (group 1 [n = 81]) without 2 49]). RESULTS: pathways as follows: (a) ileocolic vein drained inferior vena cava...
We report an X-ray optical system `Owl', capable of dark-field imaging. It comprises a Bragg case asymmetric monochromator and monolithic optics housing collimator C analyzer A that can select only the refracted light by 4,4,0 diffraction crystals 1.08 mm thickness. The angular width is 0.3 µrad at energy 35 keV. has been proven one obtain image corresponding to forward beam as well bright-field or vice versa depending on specified thickness analyzer. Images due refraction contrast in...
Two patients with glossopharyngeal neuralgia associated cardiac syncope were treated temporary pacemakers for and then microvascular decompression. The offending arteries the posterior inferior cerebellar artery in one patient anterior other. attached to nerve vagal at root entry zones. After surgery, free from did not occur after extracted. Implantation of a pacemaker perioperative period ensures safe
Patients with knee osteoarthritis can significantly affect the function of joint in terms range and mobility have a stereotypical pattern stiffness during gait, caused by an increased resistance muscles soft tissues stance phase movement. Smoothness movement, such as walking running, is assumed to be attained adulthood; however, disruptions gait due injury or performance enhancement alter smoothness this often quantified "jerk". A higher jerk value linked decrease smoothness. However few...
Abstract Regorafenib is an oral multikinase inhibitor affecting angiogenesis, oncogenesis, metastasis, and tumor immunity. As a systemic treatment, it has been shown to provide survival benefits in hepatocellular carcinoma (HCC) patients progressing on sorafenib treatment. We report herein case of HCC with hepatic vein thrombosis protruding into the inferior vena cava (IVC-HVTT) which was successfully treated by surgery following second-line chemotherapy regorafenib. A 79-year-old man...
Background and objectives: There are no reports on articular stress distribution during walking based any computed tomography (CT)-finite element model (CT-FEM). This study aimed to develop a calculation of the load response (LR) phase, most burdensome phase knee, using finite method quantitative CT images. Materials Methods: The right knee 43-year-old man who had history osteoarthritis or surgeries was examined. An image obtained extension position converted flexion angle in LR phase. bone...
Abstract Aim Obstructive colon cancer is locally advanced with poor prognosis. However, the effect of neoadjuvant chemotherapy (NAC) on obstructive remains unclear. Therefore, this study aimed to investigate safety and efficacy NAC in patients cancer. Methods From January 2012 December 2017, we collected patient data for clinical stage II/III at seven Yokohama Clinical Oncology Group (YCOG) institutions. The long‐term outcomes non‐NAC groups were analyzed retrospectively after adjusting...

This study aimed to evaluate the mechanism of progression involved in knee osteoarthritis (OA). We used computed tomography-based finite element method (CT-FEM) quantitative X-ray CT imaging calculate and create a model load response phase, wherein greatest burden is placed on joint while walking. Weight gain was simulated by asking male individual with normal gait carry sandbags both shoulders. developed CT-FEM that incorporated walking characteristics individuals. Upon simulating changes...

The ligament structures, its torn surface and articular cartilage of a sliced human joint specimen, which could not be detected by absorption contrast, were depicted clearly refraction-contrast imaging using Laue geometry analyzer crystal. image was recorded on mammography film without an intensifying screen at incident X-ray energy 15 keV. This technique will significantly improve clinical as the morphological information that are offered simultaneously.
Purpose: This study aimed to investigate the effect of knee joint structural destruction on frontal plane hip and ankle kinematics kinetics during stance phase walking in patients with differing severities osteoarthritis (KOA). Methods: An early KOA group consisted eight subjects bilateral Kellgren–Lawrence (KL) scale scores 1 or 2. established comprised nine (18 knees) KL 3 4. To measure walking, data were obtained using motion analysis system force plates. From ground reaction data, gait...
Background andObjectives: The purpose of this study was to compare the side-to-side differences in knee joint movement and moment for degree pain walking stance phase patients with bilateral osteoarthritis (KOA) comparable severity. We hypothesized that on side strong were lower compared weak pain. Materials Methods: included 11 diagnosed severe KOA. In all patients' left right knees, Kellgren-Lawrence radiographic scoring system grade level 4, femorotibial angle range motion equivalent....
Resonant magnetic Bragg scattering (RMBS) for several reflections has been measured at the Fe K -edge in 3 O 4 . The normal and X-ray absorption near-edge structure (XANES) two types of ion site (tetrahedral octahedral) were successfully determined from analysis DAFS RMBS spectra on assumption that there was an electric dipole transition. obtained XANES octahedral is well explained as a mixture 2+ 3+ ions, characteristic feature pre-edge peak mainly contributed tetrahedral site.
Though the rubella vaccination programme for adolescent girls was introduced in Japan 1977, epidemics have occurred repeatedly. Also Sasebo, 1987, we experienced various complications as follows: encephalitis (five cases), meningitis (three), thrombocytopenic purpura (four), vascular hemolytic anemia (two), pneumonia (eight), protein‐losing gastroenteropathy (one), multiple organ disorder with encephalitis, purpura, myocarditis, hepatic and renal dysfunction congenital syndrome (CRS: three)....
Fossils inside rock have been clearly visualized utilizing an X-ray interferometer. Two types of clear images are obtained, one involves phase contrast in interference beams and the other involving refraction forward-diffracted beams. 2D monochromatic synchrotron radiation with a beam size 10 mm×10 mm photon energy 35 keV was used. Using stereographic pair images, locations fossils can easily be determined precision 0.5 mm. This method powerful nondestructive tool fields paleontology...
