This paper proposes novel test techniques for high accuracy measurement of ADCs and a ramp generator on a CMOS image sensor (CIS) chip. The test circuit for the ADCs has a dual path and has an ability of multi-functional fine pattern generator that can define any input for each column to evaluate CIS specific characteristics electrically. The test circuit for the ramp generator can realize an on-chip current cell test and reject the current cell failure within 1LSB accuracy. We fabricated the test sensor using 55nm CIS process and measured the IP characteristics. Measured results show INL of 14.6LSB, crosstalk of 14.9LSB and column interference noise of 5.4LSB. These measured results agree with the designed values. By using this technique, we confirmed the accurate ADC measurement can be realized without being affected by the ambiguity of the optical input.

University graduates of professional sumo wrestlers increased rapidly during the past decade, and it came to occupy 6% of the whole of the wrestlers, 36% of the ranking sumo wrestlers (sekitori). This is about 5 times 10 years ago. The success rate that becomes the ranking sumo wrestler of the university graduates is very high with about 60%. Professional sport is considered a kind of show business by Japan, and there is history that it has thought about with money-making impure job. Therefore, the sumo wrestler hasn't been considered the occupation which the person who graduated from the university so far. But, an amateur regulation was stopped from the participation qualification of the Olympic Games in 1974 and the boundary of amateur disappeared with the professional. In other words, amateur collapsed, and a professional became a center as for sport. And, games where the amateur wrestler who graduated from the university did sumo wrestling decreased. A university graduate wrestler has the privilege of "makushita-tukedashi" at the time as the first ring, 77% of them are using this privilege. Professional Sumo Association raises a standard for this privilege and a university graduate wrestler is trying so that it starts from the rookie, too. This privilege threatens a sumo stable as a structure of rookie training school.

Objective: To evaluate whether changes in the practice of mechanical thrombectomy could affect the clinical outcomes during the coronavirus disease (COVID-19) pandemic.Methods: Patients who underwent mechanical thrombectomy from April 2019 to March 2021 for anterior circulation proximal large artery occlusion in our institute were divided into two groups of pre- and post-COVID-19, with April 2020 assumed to be the start of the COVID-19 era with the first declaration of a state of emergency. We compared patient characteristics, proportions of patient selection depending on rapid processing of perfusion and diffusion (RAPID) CT perfusion, outcomes including treatment variables such as time and reperfusion status, and patient independence at 3 months.Results: Data for 112 patients (median age, 79 years; 44 females) were included in the analysis. A total of 50 patients were assigned to the pre-COVID-19 group (45%). More patients were selected with RAPID CT perfusion in the post-COVID-19 compared with the pre-COVID-19 (69% vs. 16%; P <0.001). Treatment details and clinical outcomes did not differ between the groups, including the door-to-puncture time (median [interquartile range], 66 [54–90] min vs. 74 [61–89] min; P = 0.15), proportions of significant reperfusion (82% vs. 87%; P = 0.60), and modified Rankin scale score of ≤2 at 3 months (46% vs. 45%; P >0.99). Multivariate logistic regression analysis for the clinical outcome of modified Rankin scale score of ≤2 at 3 months was performed and included the following factors: age, sex, the onset-to-door time, significant reperfusion, and pre- and post-COVID-19. The treatment period did not influence the outcomes (post-COVID-19 group, odds ratio, 0.79; 95% confidence interval, 0.34–1.85, P = 0.59).Conclusion: In the setting of a limited access to emergency MRI during the COVID-19 pandemic, RAPID CT perfusion was performed significantly more often. Changes in the practice of mechanical thrombectomy with the protected code stroke did not bring the different level of treatment and clinical outcomes as before.

次元コンピュータ・グラフィックスでの人体モデルに人間らしい動作をつける際に,モーションキャプチャーシステムを使う場合には測定上の誤差に対する後処理的な修正が必要となることが多い。本報告ではダンス動作をキャプチャーした際の誤差修正の手段として,足先の接地状態を補助的な視覚映像に基づいて施すことの効果について,バイオロジカル・モーション刺激を用いた対比較による強制選択法による知覚評価実験と,fMRIによる脳活動計測を実施した。その結果として,修正による変化は確実に存在し,修正版を良いと判断した評価者がいる一方で,修正版は躍動感という点においては無修正版よりも低下することを示唆する結果を得た。

電磁場を組み合わせて形成させたグラフェン量子ドットの性質を詳細に研究した。電場により、ゲート電極を使用して発生させることができるであろう滑らかな量子井戸ポテンシャルが生成される。単層グラフェン内でのクライントンネル効果のために、量子井戸ポテンシャルの状態は振動的な漸近依存性をもち、したがってこの井戸のみでは電子を閉じ込めることはできない。しかしながら、均一な磁場がグラフェンシートに直交するように印加される場合は、この状態は閉じ込めに必要なように漸近的に減少する。我々は電場がランダウギャップ内にエネルギーレベルを誘起することにより、ランダウレベルのスペクトルを変化させることを見出した。これらのエネルギーレベルに対応する状態は、外場に束縛されており、その外場で調節することが可能である。これらの状態数は電場の強度に比例する。状態密度の計算結果によれば、量子状態は低密度領域内に存在し、従って量子状態は電子輸送測定を利用して実験的に探査することが可能であろう。更に我々は、スピンがブロックされたダブル量子ドットにおける電子輸送を研究した。スピン・軌道相互作用の強度を調節することにより、ダブルドットを通過する電流は、ゼロ磁場で落ち込む、あるいは2つの電子エネルギーが反交差するような磁場でピーク値になることを示した。この振舞いは、磁場およびスピン・軌道振幅による1重項と3重項との混合に依存するためである。我々は、電流の近似表現を、輸送サイクルに含まれる状態の振幅の関数として導出した。また、有限個数の核スピンを考慮した別のモデルを考え、電子と核スピンとの間にこのモデルの結果として生じる動力学を研究した。我々は、スピンアンサンブルが熱状態にあれば、一時的な電流の規則的な振動とそれに続いて、熱的ジェインズ・カミングスモデルで見られるものと類似する準カオスのリバイバルが存在することを示した。

抵抗負荷による呼吸筋トレーニング器具を用い健常成人男性7名を対象に,負荷量を変化させて呼吸筋活動を検討した。最大口腔内圧とその時の筋電活動,最大随意収縮時の筋電活動そして5段階の吸気・呼気抵抗負荷時の口腔内圧とその時の筋電活動を記録した。測定筋は吸気補助筋群(胸鎖乳突筋,僧帽筋),呼気筋群(外腹斜筋,腹直筋)である。筋電活動レベルの評価には,最大随意収縮時の筋電活動に対する百分率を用いた。結果として吸気・呼気口腔内圧と負荷量の間には,直線的な関係が認められた。また筋電活動と負荷量を二要因とする二元配置の分散分析の結果は有意な主効果が認められたが,その筋の活動は各筋群間によって差が認められた。吸気負荷では胸鎖乳突筋の筋電活動が最も高値を示し,全ての筋において筋の活動は負荷量増加に伴い直線的に増加した。呼気負荷では外腹斜筋の筋電活動が低負荷から高値を示したが,その他の筋は負荷量増加によっても著明な活動は呈さなかった。

Proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors significantly reduce low-density lipoprotein cholesterol (LDL-C) and improve the prognosis of patients with acute coronary syndrome (ACS). However, the feasibility and safety of early application of PCSK9 inhibitors on the basis of statins combined with ezetimibe to strengthen lipid lowering in extremely high-risk coronary heart disease populations are still unknown.This study was a prospective, randomized controlled study. A total of 136 patients with extremely high-risk ACS with LDL-C ≥ 3.0 mmol/L after percutaneous coronary intervention (PCI) treatment were randomly assigned 1:1 to the control group (atorvastatin 40 mg/day and ezetimibe 10 mg/day) or the evolocumab group (evolocumab 140 mg every 2 weeks combined with atorvastatin 40 mg/day and ezetimibe 10 mg/day). We compared the blood lipid profiles, major adverse cardiovascular events (MACEs), and adverse reactions. MACEs included cardiogenic death, nonfatal myocardial infarction, nonfatal stroke, and readmission due to angina. Adverse reactions included allergies, myalgia, poor blood glucose control, and liver damage.Within 1 month, the average level of LDL-C in the evolocumab group decreased from 3.54 to 0.57 mmol/L and that in the control group decreased from 3.52 to 1.26 mmol/L. The LDL-C compliance (< 1.0 mmol/L) rate was significantly increased in the evolocumab group compared with the control group (82.35% versus 22.06%, P < 0.01). The average level of lipoprotein (a) (Lp (a)) in the control group increased by 9.94 ± 51.93% from baseline after treatment, but evolocumab reduced the Lp (a) level (−38.84 ± 32.40%). Additionally, evolocumab further reduced the levels of apolipoprotein B/A1 (−70.56 ± 22.38% versus −51.29 ± 18.14%), cholesterol (−54.76 ± 18.10% versus −41.16 ± 18.14%), and apolipoprotein B (−66.47 ± 26.89% versus −46.78 ± 24.12%) compared with those in the control group, all P < 0.01. The blood lipid levels of both control and evolocumab groups stabilized after 1 month. During the 3-month follow-up, the incidence of MACEs after PCI was lower in the evolocumab group than in the control group (8.82% versus 24.59%, P = 0.015), and evolocumab combined with statins and ezetimibe did not increase the occurrence of adverse reactions (13.24% versus 11.48%, P = 0.762).In patients with extremely high-risk ACS with high levels of LDL-C, adding evolocumab to their treatment regimen as early as possible may enhance lipid lowering, increase the patient's LDL-C compliance rate in the short term, and improve cardiovascular prognosis but will not increase adverse reactions.

The expression of epidermal growth factor receptor (EGFR) and cyclooxygenase-2 (COX-2) has been reported in human nasopharyngeal and canine nasal carcinomas. The present study measured EGFR and COX-2 expression and calculated correlations between these proteins and clinical variables and outcomes in dogs with nasal carcinoma treated with radiation therapy. Before treatment, the immunohistochemistry of EGFR and COX-2 was performed in 67 biopsied tissues from canine nasal carcinomas. The correlations between these protein levels, clinical variables, and outcomes were evaluated. EGFR and COX-2 were detected in 88.1% and 82.1% of our samples, respectively. Neither EGFR nor COX-2 was associated with T stage and cribriform plate destruction. Dogs with low EGFR levels had a significantly longer survival time than dogs with high EGFR expression (P=0.043). The COX-2 expression level was not significantly associated with survival times after radiation therapy (P=0.653). Overexpression of EGFR is negatively correlated with survival in dogs with nasal carcinoma. Future studies should identify tumor biomarkers to develop therapeutic targets for effective treatments for canine nasal carcinomas.

Stevioside is natural non-caloric sweetner isolated from Stevia rebaudiana BERTONI, which has been used as a non-caloric sugar substitute in Japan. Pezzuto et al. demonstrated that steviol shows a dose-dependent positive response in forward mutation assay using Salmonella typhimurium TM677 in the presence of metabolic activation system (Aroclor induced rat liver S9 fraction). Our studies were carried out to identify the genuine mutagenic active substance from among the eight steviol derivatives. Steviol indicate almost similar levels of mutagenicity under the presence of S9 mixture, as reported by Pezzuto et al. 15-Oxo-steviol was found to be mutagenic at the one tenth the level of steviol itself under the presence of S9 mixture. Interestingly, specific mutagenicity of the lactone derivative under the presence of S9 mixture was ten times lower than that of the lactone derivative without the addition of S9 mixture.
