In order to examine fidelity to migration route, breeding, wintering, and stopover sites, we analyzed the migration of two adult Grey-faced Buzzards Butastur indicus and an adult Honey-buzzard Pernis apivorus that were satellite-tracked in East Asia for more than two migration seasons. The Grey-faced Buzzards showed a high degree of route fidelity across seasons and years. On the other hand, the migration routes of the Honey-buzzard were distinctly different between fall and spring seasons, whereas, within each season they were roughly similar between years. All three raptors were strictly faithful to their breeding and wintering sites. They also showed fidelity to several stopover sites in which the raptors stayed for relatively long periods to replenish energy. Our findings have important implications for the conservation of the migratory raptors.

我々はこれまでにスギの雄花分化が梅雨明け後の気象条件により誘導されることを報告し,梅雨明け後の気象データを用いた雄花着花量の予測式を検討した.スギ雄花分化時期は6月下旬〜9月上旬と言われている.六甲山における1999〜2003年までのスギ雄花分化の観察によると異常気象となった2002年は6月上旬という早い時期に雄花が分化した.そこで梅雨明けが早まった場合の予測式で丹波山地の着花量を計算すると6.14が得られ,実測値の6.37と非常に近似した.一方,従来法による7月の気象データで雄花着花量を求めると1.91と実測値との差は極めて大きかった.このことからスギ雄花数の予測は異常気象下であってもスギ緑枝の組織観察法により花芽分化を誘導する時期を推定し,その時期の気象解析によって精度の高い予測が可能であることが示された.

SAMPSON is the integral code for severe accident analysis in detail with modular structure, developed in the IMPACT project. Each module can run independently and communication with multiple analysis modules supervised by the analysis control module makes an integral analysis possible. At the end of Phase 1 (1994 - 1997), demonstration simulations by combinations of up to 11 analysis modules had been performed and physical models in the code had been verified by separate-effect tests and validated by inegral tests. Multi-dimensional mechanistic models and theoretical-based conservation equations have been applied, during Phase 2 (1998 - 2000). New models for Accident Management evaluation have been also developed. Verificaton and validation have been performed by analysing separate-effect tests and inegral tests, while actual plant analyses are also being in progress.

The mechanism of the Cope rearrangement of 1,5-hexadienes remains controversial. Two pathways for the rearrangement of 2,5-diphenyl-1,5-hexadiene have been debated over the past several decades. The first is a concerted route that takes place via a pericyclic transition state and the other is a stepwise process via a biradical intermediate or biradicaloid transition structure. In this study, we explored a new intramolecular trapping approach to examine the possible existence of the putative biradical that might intervene in the stepwise Cope rearrangement. For this purpose, a study was carried out in which a 1,5-hexadiene, bearing two lophyl radicals at C2 and C5 positions, moieties capable of trapping a putative biradical intermediate intramolecularly, was designed, generated, and characterized both experimentally and with density functional theory.

The purpose of this study was to verify the spatial distribution of myocardial repolarization heterogeneity using a newly developed 187-channel signal-averaged vector-projected ECG (187-ch SAVP-ECG). We constructed corrected recovery time (RTc) and Tpeak-end (corrected Tp-e) dispersion maps using a 187-ch SAVP-ECG based on vector-projection theory using a Mason-Likar lead system. We compared the spatial distribution and quantitative values of dispersion maps by 187-ch SAVP-ECG with those by 64-ch magnetocardiography (MCG) in 27 normal controls (control) and 16 patients (12 myocardial infarction (MI), and 4 dilated cardiomyopathy (DCM)). The wave pattern of the 187-ch SAVP-ECG in the representative cases was similar to those in 64-ch MCG. Spatial distribution increased RTc and corrected Tp-e dispersion maps defined by 187-ch SAVP-ECG were in agreement with those by 64-ch MCG. The value of RTc dispersion in MI was higher than that in control (41 ± 21 ms in MI versus 30 ± 12 ms in control, P < 0.05). The value of corrected Tp-e dispersion in DCM was higher than that in control (58 ± 12 ms in DCM versus 30 ± 13 ms in control, P < 0.001). There was a good correlation between RTc and corrected Tp-e dispersion values determined by 187-ch SAVP-ECG and 64-ch MCG modalities (y = 0.46x + 18, r = 0.62, P = 0.02 for RTc dispersion; y = 0.52x + 15, r = 0.63, P = 0.01 for corrected Tp-e dispersion). RTc and corrected Tp-e dispersion maps by 187-ch SAVP-ECG based on vector-projection theory can evaluate the spatial distribution of myocardial repolarization heterogeneity.

二年間にわたり、装置の設計、試作、実験を繰返えした結果として、まず水力輸送の各装置について、(1)雪分率測定機:管内を流れる雪水混合体中の雪の割合いを、試料を採取することなく、連続的に測定する装置として、実用化の目途を得た。(2)雪分率調整機:管内を流れる雪水混合体から水のみを抽出する(あるいは水を加える)ことにより、それより下流の雪の分率を調整する装置として、実用化の目途を得た。(3)雪押込機:雪を水と混合してポンプに吸い込ませるための攪はん混合装置の制御系の改善を行った。また市販のスラリーポンプの雪水混合特性を調べ、雪の水力輸送に適するものを選んだ。両者を結合して、市民の使用に適する雪押込機を製作した。つぎに、これらの装置を組合わせて、高い雪分率の輸送実験を行い、雪水二相流の流動特性について、つぎのような点を解明した。(1)流速一定の条件の下の、高い雪分率における直管内圧力損失(2)仕切り弁における圧力損失と閉塞の発生機構(3)雪塊の間欠的投入に伴う、輸送系内の雪分率の変動挙動開発された装置の市内現場における実用試験は、小雪年が続いたため、山から雪を運んで行われ、つぎのことを確認した。(1)装置は所期の輸送能力を有する。(2)閉塞は管路の収縮部における雪塊の停滞によって起る。(3)雪の投入を制御するための警報装置は所期の作動をする。しかし、この装置を市民に使ってもらって、稼動率や信頼性を知る試験は小雪のため行うことができず、今後の課題として残された。

Background: There is evidence that phosphodiesterase type-5 is effective for the treatment of pulmonary arterial hypertension (PAH). Methods and Results: A phase III, multicenter, open-label clinical trial of sildenafil 20mg t.i.d. was conducted in 21 Japanese patients with PAH to examine its efficacy, safety, and pharmacokinetics. The present trial consisted of a screening period and 12-week treatment. Patients who were enrolled in the present trial increased their 6-min walking distance of administration increased at week 12 by 84.2m from baseline. Hemodynamic parameters (eg, mean pulmonary artery pressure and pulmonary vascular resistance), Borg dyspnea scores, and plasma brain natriuretic peptide concentrations also improved compared to baseline. Most patients improved or sustained WHO functional class. Seven subjects, who were examined for the pharmacokinetics of sildefanil, showed relatively large interindividual variations in the Cmax, AUC0-8, Css,av, and Ctrough of the drug. Any serious adverse events, severe adverse events, and deaths were not observed. Most of events of undeniable causality were mild or moderate in severity. Sildefanil was well tolerated by the subjects. Conclusions: Sildenafil 20mg t.i.d. was effective and safe for Japanese patients with PAH. (Circ J 2011; 75: 677-682)

Selections of radio access networks by terminals are currently not coordinated and utilizations of the radio resources are not balanced. As a result, radio resources on some radio systems are occupied even though others can afford. In this paper, in order to provide a framework to resolve this issue, Cognitive Wireless Router (CWR) system is proposed for distributed management and independent reconfiguration of heterogeneous wireless networks. The proposed system selects appropriate operational frequency bands and radio systems to connect to the Internet in corporation between the CWRs and a server and therefore can provide optimized wireless Internet access easily even in environments without wired networks. The developed prototype system reconfigures the radio devices to connect to the Internet in 27 seconds at most. It is revealed that this reconfiguration time can be shortened to less than 100 ms by elaborating its procedure. It is also clarified that network data speed required at the server to deal with 10,000 CWRs is only 4.1 Mbps.

A 75-year-old man was admitted to our hospital in January 2010 for evaluation of syncope and abnormal ECG. ECG showed type 1 ST elevation in lead V1 and he was diagnosed as Brugada syndrome. During cardiac catheterization, baseline coronary angiography was normal, but intracoronary ergonovine maleate induced spasms of the right and left coronary arteries concomitant with chest pain and ST elevation on ECG. J waves were accentuated or newly developed. Soon after an intracoronary injection of nitroglycerin, chest pain was relieved and ischemia-induced J wave disappeared and the ST segment returned to the same morphology as baseline. Extrastimuli induced ventricular fibrillation. He received an implantable cardioverter-defibrillator. He was also treated with Ca antagonist and isosorbide dinitrate and has had an uneventful course for 5 months.

In autumn 2004, many Japanese patients with renal failure developed cryptogenic encephalopathy by consuming sugihiratake mushroom, a Japanese delicacy. To elucidate the relationship between the cryptogenic cases and this mushroom, we conducted a multivariate analysis of metabolites in ‘Probably Toxic’ sugihiratake collected from the area of encephalopathy outbreaks, and ‘Probably Safe’ sugihiratake collected from unaffected areas using UPLC/ToF MS. The results indicate that the presence of milligram quantities of vitamin D-like compounds per 10 g of dried sugihiratake from the areas of encephalopathy outbreaks. Two hypotheses to induce the encephalopathy are proposed: the found metabolites are (1) vitamin D agonists, which induce acute and severe hypercalcemia and/or hyperammonemia and/or vitamin D toxicity, or (2) vitamin D antagonists, which induce acute and severe hypocalcemia.

Sulfasalazine and corticosteroids have been used for the treatment of ulcerative colitis. Recently, it is investigated to use metronidazole for treatment of ulcerative colitis. We tried to use metronidazole for three patients with ulcerative colitis , to whom neither sulfasalazine nor corticosteroids were effective. In case 1 the patient was 37-year-old female,to whom conticosteroids had been ineffective. After treatment by metronidazole together with corticosteroids, the symptoms were improved. In case 2 the patient was 74-year-old female, who had relapsed during treatment with sulfasalazine. Treatment with metronidazole alone resulted in the remission of disease. In case 3 the patient was 32-yearold female, to whom the treatment with sulfasalazine and corticosteroids enema had been ineffecitve. By use of metronidazole together with sulfasalazine, she had remission. It seems that metronidazole is useful for the treatment of ulcerative colitis, especially in patients who did not respond to other drugs.

We investigated the seasonal occurrence, growth, age, and life history of Aurelia aurita in the Taniyama areaof Kagoshima Bay, also some of the environmental factors such as the specific gravity, pH and the temperature,influence the appearance of Aurelia aurita in the surface layer. The size of an individual depends on environmentalfactors. In contrast the number of branching points of radial water vascular canals increasing with time, independentlyof environmental factors, and therefore could be used as an age index.By using age index, the population of Aurelia aurita sampled may consist a mixture of two cohorts. Theassumption may be that the life span of Aurelia aurita is up to two years.By examining all stages of the life history of Aurelia aurita in Kagoshima Bay and comparing it with that ofother locatives, it is found that the life form of Aurelia varies with their environmental circumstances. We suggestthat how the habitat influence the life history in Aurelia should now be reviewed.
