We examined the hyperthermic and lethal toxic effects of methamphetamine in dopamine transporter (DAT) and/or serotonin transporter (SERT) knockout (KO) mice. Methamphetamine (45 mg/kg) caused significant hyperthermia even in the mice with a single DAT gene copy and no SERT copies (DAT+/- SERT-/- mice). Mice with no DAT copies and a single SERT gene copy(More)
Voice therapy is often most effective for treating patients with vocal cord polyp, polypoid degeneration and singer's nodule. However, little is known about the total speaking times in 1 day, the ratio of speech per hour and the sound level during speech, in individual patients. If these parameters can be readily detected, it could be clarified as to how(More)
We studied the relationship between the Brunnstrom stages obtained after rehabilitations and Wallerian degenerations detected by magnetic resonance imaging (MRI). Forty-nine hemiplegic patients were retrospectively studied. The patients were grouped into a low stage group (30 patients) demonstrating Brunnstrom stages I approximately IV and a high stage(More)
We investigated sports exercise effect on shortening of saccadic reaction time associated with neck extensor muscle activity. Saccadic reaction time was measured in neck rest position, 20 degrees neck flexion, and 30 % muscle contraction of the shoulder girdle elevators for two groups. These groups were an untrained group that has never belonged to any(More)
The present study was designed to examine the effect of sympathetic tonic activity on parasympathetic vasodilation evoked by the trigeminal-mediated reflex in the masseter muscle in urethane-anesthetized rats. Sectioning of the superior cervical sympathetic trunk (CST) ipsilaterally increased the basal level of blood flow in the masseter muscle (MBF).(More)
We synthesized and evaluated novel vitamin D3 derivatives with cyanoalkyl side chain at C-2 position on the basis of our previous research for 2α side chain which bears nitrogen atom-containing functional group. Through a study of X-ray co-crystal structures of human VDR and compound 3, we demonstrated that the 2α alkyl side chain in compound 3 shows a(More)

We explicitly construct two classes of infinitly many commutative operators in terms of the deformed Virasoro algebra. We call one of them local integrals and the other nonlocal one, since they can be regarded as elliptic deformations of the local and nonlocal integrals of motion obtained
We review the deformed W-algebra W q,t (sl N) and its screening currents. We explicitly construct the Local Integrals of Motion I n (n = 1, 2, · · ·) for this deformed W-algebra. We explicitly construct the Nonlocal Integrals of Motion G n (n = 1, 2, · · ·) by means of the screening currents. Our Integrals of Motion commute with each other, and give the(More)
