Investigation of the Flux Flow-inhibiting Effect of a Hole-opened Superconducting Bulk Magnet

AbstractA hole-opened bulk material has been proposed to supply magnetic flux into the large-size and high-performance bulk efficiently because superconductivity is intentionally lowered in the portion with holes. We were anxious about the flux flow in a high applied field, while it was confirmed that the flux flow was suppressed in a high applied field at a low temperature. To examine the flux flow-inhibiting effect in detail, in this paper, the time response of flux density in four portions, between the holes, the inside of the inner holes, the side opposite the holes, and the center, was measured. Although small holes served as a channel and magnetic flux flew out through a channel just after applying a pulsed field, a channel closed for up to 0.2seconds, flux flow was disturbed, and then the magnetic flux was trapped. As Jc increased with a decrease in temperature, a channel closed more quickly, and a trapped field was enhanced

Preparing for disaster: a comparative analysis of education for critical infrastructure collapse

This article explores policy approaches to educating populations for potential critical infrastructure collapse in five different countries: the UK, the US, Germany, Japan and New Zealand. ‘Critical infrastructure’ is not always easy to define, and indeed is defined slightly differently across countries – it includes entities vital to life, such as utilities (water, energy), transportation systems and communications, and may also include social and cultural infrastructure. The article is a mapping exercise of different approaches to critical infrastructure protection and preparedness education by the five countries. The exercise facilitates a comparison of the countries and enables us to identify distinctive characteristics of each country’s approach. We argue that contrary to what most scholars of security have argued, these national approaches diverge greatly, suggesting that they are shaped more by internal politics and culture than by global approaches

MAGE-A protein and MAGE-A10 gene expressions in liver metastasis in patients with stomach cancer

Tumour samples from 71 patients with stomach cancer, 41 patients with liver metastasis (group A) and 15 patients each in stages II–IV (group B) and stage I (group C) without liver metastasis were analysed. MAGE-A protein expression was evaluated by immunohistochemistry using a 6C1 monoclonal antibody and MAGE-A10 mRNA expression was detected by highly sensitive in situ hybridisation using a cRNA probe. Expressions of MAGE-A protein and MAGE-A10 mRNA in group A were detected in 65.9 and 80.5%, respectively. Both protein and gene showed significantly higher expression in group A than those in groups B (6.7, 26.7%) and C (0, 0%) (P=0.0003, P=<0.0001, respectively). MAGE-A10 mRNA expression in liver metastasis was found in eight (88.9%) out of nine patients. The concordant rate between MAGE-A family protein expression and MAGE-A10 mRNA expression in the primary sites was 81.7% (P<0.0001). MAGE-A10 gene expression was associated with reduced survival duration. The results of this study suggest that MAGE-A10 is a possible target in active immunotherapy for advanced stomach cancer

IgG4-related kidney diseases and conditions: Renal pelvic and ureteral diseases

In the literature on IgG4-related urinary tract diseases, reports of cases with involvement of the renal pelvis and ureters are increasing. IgG4-related renal pelvic and ureteral lesions accompany extra-renal organ involvement, including IgG4-related type 1 autoimmune pancreatitis, sialadenitis, and orbital disease, and are characterized by the common pathological features of IgG4-related disease (IgG4-RD), including substantial numbers of IgG4-positive plasma cells, storiform fibrosis, and stenosis in the affected organs. Similar to other mucosal organs affected in IgG4-RD, these inflammatory findings are observed within the fibroadipose tissue in the renal hilum and around the ureters. The urothelial epithelium covering the renal pelvis and ureter is preserved. Nodular lesions such as pseudotumors can also form and it is important to differentiate these from malignant tumors. At present, comprehensive diagnostic criteria that include pathological parameters have been proposed for IgG4-RD; however, obtaining diagnostic findings in small biopsy specimens is often challenging. Therefore, the diagnosis can only be rendered following careful consideration of the patient’s clinical, serologic, radiologic, and pathologic features, including the possibility of involvement in other organs. © Springer Japan 2016.[Book Chapter

T-cell responses to human papillomavirus type 16 among women with different grades of cervical neoplasia

Infection with high-risk genital human papillomavirus (HPV) types is a major risk factor for the development of cervical intraepithelial neoplasia (CIN) and invasive cervical carcinoma. The design of effective immunotherapies requires a greater understanding of how HPV-specific T-cell responses are involved in disease clearance and/or progression. Here, we have investigated T-cell responses to five HPV16 proteins (E6, E7, E4, L1 and L2) in women with CIN or cervical carcinoma directly ex vivo. T-cell responses were observed in the majority (78%) of samples. The frequency of CD4+ responders was far lower among those with progressive disease, indicating that the CD4+ T-cell response might be important in HPV clearance. CD8+ reactivity to E6 peptides was dominant across all disease grades, inferring that E6-specific CD8+ T cells are not vitally involved in disease clearance. T-cell responses were demonstrated in the majority (80%) of cervical cancer patients, but are obviously ineffective. Our study reveals significant differences in HPV16 immunity during progressive CIN. We conclude that the HPV-specific CD4+ T-cell response should be an important consideration in immunotherapy design, which should aim to target preinvasive disease
