When comparing the IPI to the CI and CPI, the results revealed that the Piezo-ICSI using flat-tipped micropipettes with a wall thickness of 0.625 μm significantly improves survival, fertilization, good-quality day-3 embryo, pregnancy, and live birth rates.

The measurement method of three-dimensional posture and flying trajectory of lower body during jumping motion using body-mounted wireless inertial measurement units (WIMU) is introduced. The WIMU is composed of three-dimensional (3D) accelerometer and gyroscope of two kinds with different dynamic range and one 3D geomagnetic sensor to adapt to quick movement. Three WIMUs are mounted under the chest, right thigh and right shank. Thin film pressure sensors are connected to the shank WIMU and are installed under right heel and tiptoe to distinguish the state of the body motion between grounding and jumping. Initial and final postures of trunk, thigh and shank at standing-still are obtained using gravitational acceleration and geomagnetism. The posture of body is determined using the 3D direction of each segment updated by the numerical integration of angular velocity. Flying motion is detected from pressure sensors and 3D flying trajectory is derived by the double integration of trunk acceleration applying the 3D velocity of trunk at takeoff. Standing long jump experiments are performed and experimental results show that the joint angle and flying trajectory agree with the actual motion measured by the optical motion capture system.

1 To elucidate the possible involvement of pertussis toxin (PTX)-sensitive G proteins in the post receptor mechanism of a 2 -adrenoceptors and imidazoline receptors, we examined the e ect of pretreatment of the central nervous system with PTX on the antidysrhythmic e ect of dexmedetomidine, a selective a 2 -adrenoceptor agonist, and rilmenidine, a selective I 1 -imidazoline receptor agonist on halothane-adrenaline dysrhythmias in rats. 3 It is suggested that central I 1 -imidazoline receptors as well as a 2 -adrenoceptors may be functionally coupled to PTX-sensitive G proteins.

This paper describes the seismic design of Japan Sodium-Cooled Fast Reactor (JSFR), which includes the seismic condition, the seismic isolation system, and the seismic evaluation of the primary components. Since the design seismic loading is set out severely than ever since The Niigata-ken Chuetsu-oki Earthquake in 2007, an advanced seismic isolation system is aimed to reduce the seismic force loaded on the primary components of JSFR to be less than that of the previous seismic isolation system. The advanced seismic isolation system is developed by optimizing the performance based on the previous seismic isolation system considering the natural frequency of the primary components. The laminated rubber bearings thicker than the previous ones and oil dampers are adopted for the advanced seismic isolation system of SFR. The seismic evaluation of nuclear reactor components applying the advanced seismic isolation system is performed and its feasibility is confirmed.

We made a paediatric anaesthesia mask suitable for fibreoptic intubation by modifying a commercially available disposable mask with a ventilation port (Vent port) on a side. We added a large fibreoptic port (FO port, 22 mm in ID) in the middle of the mask to allow the passage of all sizes of paediatric tracheal tubes. This FO port was covered with an elastic rubber membrane to allow air-tight fibrescopic manipulation Fibreoptic intubation was performed safely through the FO port under continuous manual ventilation with anaesthetic gases via a Vent port connected to the breathing circuit. We succeeded in tracheal intubation in several infants and children with difficult airway in less than ten min, mainly via the nasotracheal route. This fibreoptic mask provides a safer technique for fibreoptic intubation in patients with difficult airways, especially in infants and small children.

A four-month-old male infant with basal encephalocele of the transsphenoidal type presented with upper airway obstruction and facial midline deformity, including cleft lip, cleft palate, hypertelorism and exophthalmos. Basal encephalocele is a rare disease, and usually not detectable from the outside. In this case, initially the cause of an upper airway obstruction was considered to be posterior rhinostenosis, and posterior rhinoplasty with inferior nasal conchectomy was scheduled. However, in preoperative examination, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a bony defect in the sphenoidal bone and a cystic mass in communication with cerebrospinal fluid, herniating into the nasal cavity through the bony defect. The mass was diagnosed as a transsphenoidal encephalocele, the scheduled operation cancelled, and tracheostomy performed for airway management. The possibility of basal encephalocele should be considered in the case of upper airway obstruction with facial midline deformity.

MHs in vitrectomized eyes can show repeated recurrence and spontaneous closure.

In Japan, several kinds of three-dimensional seismic isolation system for next-generation nuclear power plant such as fast reactors have been studied in recent years. We proposed a structural concept of a vertical component isolation system, assuming a building adopting a horizontal base isolation system. In this concept, a reactor vessel and major primary components are suspended from a large common deck supported by isolation devices consisting of large coned disk springs. In order to verify the isolation performance of the vertical component isolation system, 1/8 series of shaking table tests using a scale model were conducted. The test model was composed of 4 vertical isolation devices, common deck and horizontal load suspension system. For the design earthquake, the system smoothly operated, and sufficient isolation characteristics were shown. The simulation analysis results matched well the test results, so the validity of the design technique was able to be verified. As the result, the prospect that the vertical isolation system applied to the FBR plant could technically realize was obtained.
