    Notes: Several studies have examined the functional relationship between mandibular movement and head or body posture, but head and body motion during jaw movement have not been extensively investigated. Ten healthy participants performed repetitive jaw tapping movement. Piezoelectric accelerometers were attached on the surfaces of the participant's forehead, mentum, and over the spinous processes of the sixth cervical, twelfth thoracic and third lumbar vertebrae. The direction in which the antero-posterior acceleration signals appeared around the onsets of jaw opening and closing were observed for the period from the 6th to the 25th strokes of the jaw tapping. Around the onset of jaw opening, the forehead and the lumbar vertebra tended to move posteriorly, but the cervical and thoracic vertebrae moved anteriorly with significant frequencies. The directions of the motions of these locations reversed themselves at the beginning of jaw closing; so the motions of the forehead and the lumbar vertebra were opposed again to the ones of the cervical and thoracic vertebrae. The results suggest that the head extend–flex motion often accompanied the jaw open–close movement, and the motions of the neck and trunk existed, which would serve the purpose of promoting the mandible to move smoothly.

    Leiomyoma with atypical cells (atypical leiomyoma) in the larynx (1999)

    Notes: To report and confirm the identity of laryngeal leiomyoma with many atypical cells, which has not been described previously.〈section xml:id="abs1-2"〉〈title type="main"〉Case detailsA 53-year-old man was found to have a polypoid tumour in the larynx. The tumour was excised and the patient has shown no evidence of recurrence over a 5-year period. The tumour tissue comprised intersecting fascicles of spindle-shaped tumour cells with blunt-ended nuclei. Many of the tumour cells showed marked atypia. Mitotic activity in the tumour cells was low, and no atypical mitoses were found. Immunohistochemically, the tumour cells were positive for smooth muscle actin and desmin. p53 overexpression was identified in many tumour cells; the p53 labelling index of the tumour cells was 45%. DNA from tumour cells showed loss of heterozygosity on chromosomes 3p, 5q, 8p, 9p, 10q, 17p and 18q. We diagnosed this case as leiomyoma with atypical cells (atypical leiomyoma) based on the clinical course and pathological and genetic findings.〈section xml:id="abs1-3"〉〈title type="main"〉ConclusionThis is the first report of atypical leiomyoma in the larynx. The clinical course and pathological findings indicate that although laryngeal atypical leiomyoma contains numerous atypical cells, it is a benign neoplasm.

    Observation of the Energy Gap above T c in (Bi,Pb)2Sr2Ca2Cu3O10+δ using Break-Junction Tunneling (1999)
    Springer
    Journal of low temperature physics 117 (1999), S. 359-363

    Notes: Abstract Tunneling measurements of (Bi,Pb) 2 Sr 2 Ca 2 Cu 3 O 10+δ have been carried out with break junction to study the gap feature above T c = 106 K. The decreasing gap magnitude with increasing the temperature does not disappear at T c for the most significant data. The gap-closing temperature is found to be T* ≃ 160 K.

    Effect of gas evolution at solid-liquid interface on contact angle between liquid Si and SiO2 (1999)

    Notes: Abstract The contact angle between liquid Si and SiO2 was measured with the sessile drop method at 1723 K. The contact angle changed very unusually due to the evolution of SiO gas at the solid/liquid interface. It was found that the real contact angle between liquid Si and SiO2 is about 80° or less at 1723 K though the apparent contact angle of 95° was observed for a long time during the experiment. The difference in the contact angle can be explained with a model of a composite material. Although the real contact angle is more important in a physical point of view, the apparent contact angle should be adopted in some cases such as simulation works.
