Suboccipital Approach for Primitive Trigeminal Artery Obliteration Associated with Cavernous Aneurysm

OBJECTIVE: A 63-year-old woman presented with diplopia resulting from abducens paralysis. Examination revealed a giant cavernous aneurysm supplied by the internal carotid artery (ICA) and primitive trigeminal artery (PTA) via the vertebrobasilar system. METHODS: After evaluation of balloon test occlusion (BTO) at the distal side of the PTA origin, the aneurysm was treated with PTA obliteration through the suboccipital route in the lateral position followed by cervical carotid ligation with superficial temporal artery-to-middle cerebral artery anastomosis in the supine position. RESULTS: The aneurysm showed marked shrinkage after the surgery. CONCLUSION: PTA obliteration through the retrosigmoid opening is a therapeutic surgical option in a patient with a cavernous aneurysm supplied by the PTA.ArticleWORLD NEUROSURGERY. 74(4-5):494-496 (2010)journal articl

Improvement of resistance against hydrogen embrittlement by controlling carbon segregation at prior austenite grain boundary in 3Mn-0.2C martensitic steels

This study challenged to improve the resistance against hydrogen embrittlement by increasing the concentration of carbon segregated at prior austenite grain boundary (PAGB), XPAGB, in low-carbon martensitic steels. The specimens with/without carbon segregation treatment (Non-seg and Seg specimens, respectively) had almost the same microstructure, other than higher XPAGB in the Seg specimen. While the uncharged Non-seg and Seg specimens exhibited similar mechanical properties, the maximum stress of the hydrogen-charged specimen was much higher in the Seg specimen than that in the Non-seg specimen even when diffusible hydrogen contents were almost the same. In addition, the fraction of intergranular fracture surface was much smaller in the Seg specimen. Based on these results, we conclude that the segregated carbon suppressed the accumulation of hydrogen around PAGB by site competition and increased cohesive energy of PAGB, leading to the significantly improved resistance against hydrogen-related intergranular fracture

Inverted ductal papilloma arising from the buccal minor salivary gland: A case report and immunohistochemical study

AbstractOral inverted ductal papilloma is a rare, benign epithelial tumor that exhibits an endophytic growth pattern and is found almost exclusively in the minor salivary glands. We report on a case of inverted ductal papilloma in the buccal mucosa. We also performed an immunohistochemical study. The tumor cells were positive for cytokeratin and epithelial membrane antigen, while negative for calponin, S-100 protein, α-SMA, vimentin, and desmin. This result indicated that the lesion arises from the excretory duct near the oral mucosal surface but not the myoepithelial cells. In addition, Ki-67 labeling index of 3.96% indicated the low level of proliferation

Lesson Study Consulting for the Professional Development of Textbook Developers: A case of social studies textbook development project for the Ministry of Education, Youth and Sport in Cambodia

Who should disseminate new curriculum and textbooks from the central government to classroom in developing countries? And, how is it possible? Curriculum and textbook developers often faces the necessity of and the challenges in spreading the essentials and intention of new curriculum and textbooks and the expected educational practices to classroom. In order to design and implement consistent educational reform through three layers of the curriculum (the intended, the implemented and the attained level), it is required for them to be committed in not only the development stage with a clear picture of quality teaching and learning, but also the dissemination stage through in-service teacher training such as lesson study. This study aims at clarifying potential measures to develop the expertise for curriculum and textbook developers as a communicator of educational reform in developing countries. In the process of our project on the curriculum and textbook development of social studies education in Cambodia, we assume “the expertise of consulting lesson study” and examine it both from theory and practical cases of (i) lesson-demonstrating approach and (ii) lesson-advising approach. As a consequence, it is found that their ability for consulting lesson study could be enhanced by regarding senior (Japanese) experts as a role model. And also, the result implies that, for their continuous professional development, it is necessary for them to purposefully take part in lesson study consulting, and shift the approach from “modeling” to “coaching” by steps

Effects of mosapride on motility of the small intestine and caecum in normal horses after jejunocaecostomy

The purpose of the present study was to evaluate the prokinetic effects of mosapride with non-invasive assessment of myoelectrical activity in the small intestine and caecum of healthy horses after jejunocaecostomy. Six horses underwent celiotomy and jejunocaecostomy, and were treated with mosapride (treated group) at 1.5 mg/kg per osos once daily for 5 days after surgery. The other six horses did not receive treatment and were used as controls (non-treated group). The electrointestinography (EIG) maximum amplitude was used to measure intestinal motility. Motility significantly decreased following surgery. In the treated group, the EIG maximum amplitude of the small intestine was significantly higher than in the controls from day 6~31 after treatment. These findings clearly indicate that mosapride could overcome the decline of intestinal motility after jejunocaecostomy in normal horses

Archaeological Finds from Jinseki-kōgen Town: The “INOHIRA Collection” from Toyomatsu Village

The Department of Archaeology at Hiroshima University has carried out archaeological surveys at Jōmon rock shelters and cave sites in the vicinity of Taishaku-kyō in northeastern part of Hiroshima Prefecture for more than 50 years. However, to date, open sites in this region have not been investigated respectively, because none have been detected. A range of open sites in the vicinity of Taishaku-kyō were located and surveyed in this study in order to develop hypotheses regarding modes-of-life during the Jōmon period. Thus, one initially investigated a series of finds that had already been unearthed by chance as the result of agricultural land consolidation or cultivation in Toyomatsu village in the northern part of town of Jinseki-kōgen, formerly Toyomatsu village in the Jinseki district (gun). This town is located on the eastern side of the Taishaku-kyō area and all the artefacts examined were the property of the late Mr. Gunji INOHIRA, who collected them, compiled records, and left a series of documents regarding the remains of these sites before they were destroyed more than 20 years ago. These documents are therefore important reference materials enabling a deeper understanding of the archaeological sites in Toyomatsu village. This collection includes pottery of the Jōmon and Yayoi period, as well as stone tools from the Late Jōmon and the Middle Yayoi periods, and Sue ware, beads (necklaces), and ironware etc. from the Late Kofun period. The important “INOHIRA collection” is introduced in this report and some considerations regarding the archaeological sites in Toyomatsu village are presented

The relationship between ambulatory ability before surgery and the D-dimer value after total hip arthroplasty: the evaluation of ambulatory ability by the timed "Up & Go" test.

We examined whether ambulatory ability before surgery might influence the post-operative D-dimer level after total hip arthroplasty (THA). One hundred two patients with hip osteoarthritis receiving THA were included in the current study. The patients were all female, and their ages ranged from 45 to 81 (average 65.0 +- 9.3 years). Age, operated side, body mass index (BMI), disease duration before surgery, pre-operative pain evaluated by visual analogue scale (VAS), total cholesterol value, maximal circumference of the lower leg of the operated side, and timed &#34;Up &#38; Go&#34;test (TUG) before surgery, were retrospectively investigated to examine their relationship with D-dimer levels on post-operative day 7. Patients were divided into 2 groups according to the D-dimer value: over 10 microg/ml (Group D), and under (Group N). Patients in group D (N= 52)were older, had a higher BMI, and had less ambulatory ability than patients in group N (N= 50). As age showed a relationship with the D-dimer value on the 7th day and TUG results, patients in the 2 groups were further subdivided into 50's, 60's, and 70's age brackets. In the 50's bracket, patients in group D had higher BMI than patients in group N, but time for TUG was not significantly different. In the 60's and 70's bracket, patients in group D had less ambulatory ability than patients in group N, but the time for TUG was not directly correlated with the D-dimer value. The results suggest that pre-operative low ambulatory ability in patients with osteoarthritis over 60 years might influence the postoperative D-dimer after THA, indicating the potential risk for post-operative deep venous thrombosis.</p
