Echolocating horseshoe bats respond to flight-speed induced shifts in echo frequency by adjusting the frequency of subsequent calls. Under natural conditions, Doppler effects may force the frequency of a returning echo several kilohertz above the original emission frequency. By lowering subsequent call frequencies, the bat can return echo frequencies to within a narrow spectral bandwidth to whi...

Nitroglycerin (TNG) causes a prolonged dilatation of coronary collaterals. To demonstrate a functional significance of this dilatation we measured the effect of TNG on myocardial contractile force in dogs 2(1/2)-4 wk after the left anterior descending coronary artery (LAD) had been embolized in closed-chest animals. Development of collaterals was documented by angiography. Via a left thoracotom...

Rat sperm that are demembranated with Triton X-100 and reactivated with Mg-ATP show a strong mechanical response to the presence of free calcium ion. At pCa < 4, the midpiece region of the flagellum develops a strong and sustained curvature that gives the cell the overall appearance of a fishhook [Lindemann and Goltz, 1988: Cell Motil. Cytoskeleton 10:420-431]. In the present study, the force a...

One of structural passive control methods is to use Tuned Liquid Damper (TLD). However, because of the nature of the TLD, only one tuning frequency can be created when the water is sloshing. To fix this problem, some installed rotatable baffles can be embedded inside TLD called Variably Baffled TLD (VBTLD) where by changing the angle of the baffles a tuning frequency range is created. This gives ...

As a common belief among rehabilitation specialists, the purpose of rehabilitation has been restoring some of a person's physical and mental capabilities that have been lost as a result of disease, illness, or injury and to help achieve the highest possible level of function, independence, and quality of life. Goals of rehabilitation for different populations differ. Older adults usually focus ...

私は 2015 年 61 歳時に左視床出血のため倒れ, 失語症と右半身麻痺となった。約 1 ヵ月間意識のなかった時期を経てわずかに反応がみられるようになった。その後は経口摂取の訓練や端座位などからはじまるリハビリが毎日の主な治療となった。徐々に言葉が出るようになり, 装具を使用して歩行距離も徐々に伸びていった。発症後 7 ヵ月で自宅にもどり, 勤務していた病院で患者さんのインタビューと脳波の判読を行った。同じ頃, 筋肉の拘縮改善目的で A 型ボツリヌス毒素製剤療法と, 運動機能回復のため経頭蓋磁気刺激療法も開始された。勤務していた病院を退職し発症から 5 ヵ月後, 南東北医療クリニックで週に 回心療内科の外来を担当させていただいている。右半身麻痺と言葉の出にくさはあるものの日常会話では不自由はない。 ここまでこられたのは支えて頂いた医師, 看護師, 言語聴覚士, 理学療法士, 作業療...
