低線量率(20 mGy/ 22 h/ day)のγ線を連続照射したB6C3F1雌マウスでは、非照射対照マウスと比較して、有意に体重が増加することが分かった。この照射マウスに認められる体重増加の機構を明らかにするために、20 mGy/ 22 h/ dayのγ線を9週齢から44週齢まで連続照射したB6C3F1雌マウスの脂肪組織重量、肝臓及び血清中の脂質含有量、糖代謝及び脂質代謝に関連した因子(インスリンやアディポサイトカイン等)と卵巣の機能変化を調べた。組織の脂肪化を伴う有意な体重の増加は、20 mGy/ 22 h/ dayのγ線を連続照射したB6C3F1雌マウスにおいて28週齢から44週齢に至まで認められた(集積線量2.7-4.9 Gy)。卵巣及び膣垢標本の病理学的解析から、連続照射マウスでは、卵母細胞の枯渇による早期の閉経と同時に体重増加が起こることが分かった。以上の結果から20 mGy/ 22 h/ dayのγ線を連続照射したB6C3F1雌マウスでは、早期の閉経が引き金となって、体重増加が起こることが示唆される。本研究は、青森県からの受託事業により得られた成果の一部である。

[Purpose] The aim of this study was evaluate the effect of a sling exercise on shoulder subluxation in stroke patients. [Subjects] The subjects of this study were thirty-four stroke patients with subluxation. They were randomly selected and divided into two groups. [Methods] The subject group (n=17) performed the sling exercise with traditional therapeutic exercise. The control group (n=17) performed only traditional therapeutic exercise. [Results] The results indicate that improvement of corrected vertical distance (cVD), and the ratio of the oblique distance of the affected and unaffected sides (rOD) was greater in the experimental group than in the control group. [Conclusion] We suggest that the sling exercise is effective at reducing the severity of hemiplegic shoulder subluxation in post-stroke patients.

沖縄に分布する代表的な3種土壌(国頭マージ,島尻マージおよびジャーガル)における米ぬか混和のサツマイモネコブセンチュウに対する防除効果の評価を行った.その結果,全ての土壌において高い防除効果が認められた.また,各土壌の米ぬか混和処理では根こぶ線虫数が顕著に減少するとともに,対照に比べて細菌食性線虫が増加する傾向を示した.さらに米ぬか混和処理土壌の微生物相を調査した結果では,対照に対して,国頭マージおよび島尻マージでは放線菌および糸状菌数が増加する傾向を示したが,ジャーガルでは糸状菌数のみの増加が認められた.細菌のグラム判定試験では,いずれの米ぬか処理土壌においてグラム陽性細菌が増加した.またネコブセンチュウの分離に及ぼす米ぬかの影響を検討した結果では,迅速かつ顕著な分離阻害効果が認められた.以上のことから,米ぬか処理は供試した全ての土壌においてネコブセンチュウに対し高い防除効果を示すことが明らかとなった.The controlling effect of rice bran mixture on M. incognita in three typical soil types of Okinawa was evaluated. A high control effect was observed in all soils examined; the number of M. incognita decreased while that of bacteriotrophic nematodes increased strongly in soils with the organic matter added. The application of rice bran increased fungal growth in Jahgaru soil, and that of fungi as well as of actynomycetes in Kunigami mahji and Shimajiri mahji. Ggram-positive bacteria were promoted in all soils by the admixture of rice bran. Moreover, as a result of examination of the influence of rice bran mixture on extraction of M. incognita, an inhibitory effect that prompt and remarkable was admitted. We conclude that a significant inhibition of M. incognita could be achieved in all soil types by the application of rice bran.

本研究では,露地における米ぬか混和・太陽熱併用処理のネコブセンチュウに対する効果を検討した.その結果,植物体の成長および収量が良く,最もネコブセンチュウに対する防除効果が高い処理法は,1重被覆・米ぬか混和併用処理であった.太陽熱処理単独,米ぬか混和・太陽熱併用処理の土壌微生物に及ぼす影響を調査した結果では,両処理とも糸状菌数の低下が認められたが,後者では緩和された.また線虫密度に関しても,前者ではネコブセンチュウだけでなく,自活性線虫に対しても影響が強いが,後者ではやや緩和された.以上のことからオクラのネコブセンチュウ防除において最も有効な処理法は1重被覆・米ぬか混和処理であると考えられた.In this study the effect of use of rice bran together with solar heat treatment in the fields on southern root-knot nematode that is one of the important parasite on okra is examined. As a result, the treatment having most effectiveness on controlling the nematode and on the plant growth and on the yield was the combination of the single covering and rice bran mixture method. The effect of single treatment with solar heat and using rice bran and solar heat in combination on the micro flora in soil showed that fungi decreased in number on both treatments but the effect was relieved by the combinational treatment. As for the nematode density, the single solar heating had a strong influence on free-living nematodes as well as on southern root-knot nematode but it was alleviated by the combination. From the results mentioned above, it is conceivable that the best control method of southern root-knot nematode infested on okra is combination method of single covering and rice bran treatments.

Sesoko Station, Okinawa, has been the site of many significant advances in coral reproductive research and it continues to be a preferred destination for both Japanese and international researchers. Consequently, there are decades of spawning observations, which we present and explore here with the aim of making it easier to predict when species spawn at Sesoko Station. The data include over 700 spawning observations from 87 species of reef-building hermatypic corals. Almost all spawning occurred between dusk and dawn, with most spawning activity concentrated in the 2 to 4 hours after sunset. Some phylogenetic patterns were evident: most Acropora species spawn on or around the 6th full moon after December 21st (the northern hemisphere winter solstice); spawning in common species of merulinids and Porites appears to be concentrated around the 7th full moon and spawning in the fungiids around the 8th and subsequent full moons. The night of peak spawning with respect to the night of the full moon varied considerably among years in common Acropora species, but was dependent on the calendar date of the full moon in May or June. Therefore, despite an extended spawning season of over three months and considerable variation in the calendar date of spawning in many species among years, the month and night of spawning are reasonably predictable for many species enhancing the value of Sesoko Station as a site for coral reproductive research.

Influenza is a contagious, acute respiratory disease caused by the influenza virus. The mucosal lining in the host respiratory tract is not only the site of virus infection, but also the site of defense; it is at this site that the host immune response targets the virus and protects against reinfection. One of the most effective methods to prevent influenza is to induce specific antibody (Ab) responses in the respiratory tract by vaccination. Two types of influenza vaccines, intranasal live attenuated influenza virus (LAIV) vaccines and parenteral (injectable) inactivated vaccines, are currently used worldwide. These vaccines are approved by the European Medicines Agency (EMA) and the US Food and Drug Administration. Live attenuated vaccines induce both secretory IgA (S-IgA) and serum IgG antibodies (Abs), whereas parenteral vaccines induce only serum IgG Abs. However, intranasal administration of inactivated vaccines together with an appropriate adjuvant induces both S-IgA and IgG Abs. Several preclinical studies on adjuvant-combined, nasal-inactivated vaccines revealed that nasal S-IgA Abs, a major immune component in the upper respiratory tract, reacted with homologous virus hemagglutinin (HA) and were highly cross-reactive with viral HA variants, resulting in protection and cross-protection against infection by both homologous and variant viruses, respectively. Serum-derived IgG Abs, which are present mainly in the lower respiratory tract, are less cross-reactive and cross-protective. In addition, our own clinical trials have shown that nasal-inactivated whole virus vaccines, including a built-in adjuvant (single-stranded RNA), induced serum hemagglutination inhibition (HI) Ab titers that fulfilled the EMA criteria for vaccine efficacy. The nasal-inactivated whole virus vaccines also induced high levels of nasal HI and neutralizing Ab titers, although we have not yet evaluated the nasal HI titers due to the lack of official criteria to establish efficacy based on this parameter. Data suggest that adjuvant-combined nasal-inactivated vaccines have advantages over the current injectable vaccine because the former induce both S-IgA and serum IgG Abs. In addition, nasal-inactivated vaccines seem to be superior to the LAIV vaccines, because non-infectious preparations could be used in high-risk groups. Thus, the development of intranasal inactivated vaccines is recommended, because such vaccines are expected to improve the efficacy of influenza vaccines.

Quercetin, a type of flavonoid, is believed to reduce age-related cognitive decline. To elucidate its potential function, we carried out a randomized, double-blind, placebo-controlled, parallel-group comparative clinical trial involving 24-week continuous intake of quercetin-rich onion compared to quercetin-free onion as a placebo. Seventy healthy Japanese individuals (aged 60 to 79 years old) were enrolled in this study. We examined the effect of quercetin-rich onion (the active test food) on cognitive function using the Mini-Mental State Examination, Cognitive Assessment for Dementia iPad version, and Neuropsychiatric Inventory Nursing Home version. The Mini-Mental State Examination scores were significantly improved in the active test food group (daily quercetin intake, 50 mg as aglycone equivalent) compared to the placebo food group after 24 weeks. On the Cognitive Assessment for Dementia iPad version for emotional function evaluation, we found that the scores of the active test food group were significantly improved, suggesting that quercetin prevents cognitive decline by improving depressive symptoms and elevating motivation. On the Neuropsychiatric Inventory Nursing Home version, we found significant effects on reducing the burden on study partners. Taking all the data together, we concluded that 24-week continuous intake of quercetin-rich onion reduces age-related cognitive decline, possibly by improving emotional conditions. Clinical trial register and their clinical registration number: This study was registered with UMIN (approval number UMIN000036276, 5 April 2019).

Weighted Round-Robin (WRR) is often used, due to its simplicity, for scheduling packets or tasks. With WRR, a number of packets equal to the weight allocated to a flow can be served consecutively, which leads to a bursty service. Interleaved Weighted Round-Robin (IWRR) is a variant that mitigates this effect. We are interested in finding bounds on worst-case delay obtained with IWRR. To this end, we use a network calculus approach and find a strict service curve for IWRR. The result is obtained using the pseudo-inverse of a function. We show that the strict service curve is the best obtainable one, and that delay bounds derived from it are tight (i.e., worst-case) for flows of packets of constant size. Furthermore, the IWRR strict service curve dominates the strict service curve for WRR that was previously published. We provide some numerical examples to illustrate the reduction in worst-case delays caused by IWRR compared to WRR.

A flow-diverter (FD) device is a well-established tool for the treatment of unruptured intracranial aneurysms. Time-of-flight (TOF) MR angiography (MRA) is widely used for postoperative assessment after the treatment with FD; however, it cannot fully visualize intra-aneurysmal and intrastent flow signals due to the magnetic susceptibility from the FD. Recently, the utility of MRA with ultra-short TE (UTE) sequence and arterial spin labeling technique in assessing the therapeutic efficacy of intracranial aneurysms treated with metallic devices has been reported, but long image acquisition time is one of the drawbacks of this method. Herein, we introduce a novel UTE MRA using the subtraction method that enables the reduction in susceptibility artifacts with a short image acquisition time.

Expression is the key feature of the post-modern model of culture today, not only in the field of industry but also the definition of man, comparing to Creation which is the key concept of the classic-western-modern model of the society and man. This essay is focused to the syntactic function of Narrator in classic Japanese literature text, as the tale of Genji, which is highly suggestive to study of post-modern expression technology. With referring to Vilem Flusser's philosophical approach to Tools and Chiyuki Kumakura's literary analysis to Genji, I tried to depict ontological structure of adjectival subject in Japanese language and cognition, as which would provide our ways of expressionist today.

Background:Optical coherence tomographic (OCT) imaging has enabled identification of lipid, with increasing interest in how it may affect coronary interventions and clinical outcomes. This review summarizes the available evidence around OCT identification of lipid and its effect on interventions, clinical events, and the natural history of coronary disease.Methods and Results:We conducted a scoping review using the Medline, HealthStar, and Embase databases for articles published between 1996 and 2021. We screened 1,194 articles and identified 51 for inclusion in this study, summarizing the key findings. The literature supports a common OCT definition of lipid as low-signal regions with diffuse borders, validated against histology and other imaging modalities with acceptable intra- and inter-rater reliability. There is evidence that OCT-identified lipid at the site of stent implantation increases the risk of edge dissection, incomplete stent apposition, in-stent tissue protrusion, decreased coronary flow after stenting, side branch occlusion, and post-procedural cardiac biomarker increases. In mostly retrospective studies, lipid indices measured at non-stented sites are associated with plaque progression and the development of recurrent ischemic events.Conclusions:There is extensive literature supporting the ability of OCT to identify lipid and demonstrating a substantial impact of lipid on percutaneous coronary intervention outcomes. Future work to prospectively evaluate the effect of the characteristics of lipid-rich plaques on long-term clinical outcomes is needed.
