    Notes: Efforts were made to obtain anisotropic thin-film magnets at low substrate temperature. This is an important criterion for practical applications such as to build motors. The influence of substrate materials as well as film thickness on the c-axis orientation were studied. It has been shown that thin-film magnets with the easy axis of magnetization normal to the film plane could be deposited at a substrate temperature of around 450 °C by choosing the composition near the line from Nd13Fe76B11 to Nd13Fe70B17 in the ternary phase diagram. It was found that the anisotropic film magnets could be also deposited on the metallic substrate. The c-axis orientation tended to be isotropic with an increase in film thickness. The obtained results were used to fabricate a milli-size motor by depositing 20-μm-thick Nd–Fe–B films on a silicon steel disk substrate of 5-mm diam. The milli-size motor exhibited a torque of 0.8 g mm at a rotational speed of 3000 rpm.

    Notes: We demonstrate the alteration of spontaneous emissions in semiconductor microcavity triodes, in which the carriers are injected by current into a single quantum well (QW) active region and the emission wavelength was varied by the voltage applied to the QW through the quantum confined Stark effect. The clear changes in the emission spectra and radiation patterns with the change of the voltage manifest that the spontaneous emission is well modified by the microcavity under the control of the applied voltage. © 1999 American Institute of Physics.

    Notes: A new portable system for measuring nocturnal tooth contacts has been devised. This system was suitable for patients to take home and record tooth contacts by themselves. A micro photo sensor using optical fibres was applied to detect tooth contacts. The sensor and the target were accurately fixed to opposed molars, respectively on the same side, with removable metal attachments. Patients were instructed to set the attachment to their tooth each experimental night. In the present study, data was assembled for four or five nights in three subjects who were free of masticatory pain and dysfunction. Each subject showed an individual tooth contact pattern. It is suggested that this new system is useful and convenient for measuring nocturnal tooth contacts.

    Application of a newly developed 3-D deformation measurement system to prosthetic dentistry (1996)

    Notes: summary A new system for measuring threedimensional deformation has been developed. The main components of the system are a fixed TV camera and vertically scanning projectors. The advantages of the system are: (1) since there is no mechanical contact between the object and the sensing unit, hardness and form of the object do not have to be considered; (2) the system does not need any precise geometry except for the reproducibility of the vertical scanning stage; (3) the time required for one measurement is extremely short; and (4) the system is not expensive. From the basic experiments for testing accuracy, this system has about ± 30 μm range deviation against 1000 μm deformation of the object. The system has been applied to investigate the influence of various impression procedures for a removable partial denture on the displacement of the simulated soft mucosal tissue. It is revealed that deformation forms are expressed precisely. Our results suggest that this measurement system is quite useful for research in dentistry and that it could be widely applied.

    Tooth contact patterns in patients with temporomandibular dysfunction (1991)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The occlusal tooth contact patterns in patients with temporomandibular dysfunction and normal subjects were studied under a range of conditions using a newly devised radiotelemetry system. The patterns in the patient group were completely different from those in the control group. During rest or work, the patients showed higher values for total number and time of tooth contacts, as well as several contacts of extended duration. Moreover, many of the tooth contacts during swallowing were plural contacts in the patient group. These results suggest that patients with temporomandibular dysfunction exhibit increased tonus of jaw-closing muscles, which is probably due to occlusal disharmonies and psychological stress.

    Does chewing performance depend upon a specific masticatory pattern? (1999)
    Oxford, UK : Blackwell Science Ltd
    Journal of oral rehabilitation 26 (1999), S. 0

    Notes: The purpose of this article is to review the literature concerning the ideal chewing pattern for best chewing performance. We conclude that at this time there is not one ideal chewing pattern which can be used clinically or in research to assess the health of the mastication apparatus nor to predict chewing performance. It is clear that human masticatory behaviour is one of the most complex human behaviours. Chewing is under the control of the central pattern generator located in the brain stem but is influenced by dental and temporomandibular joint morphology. The most important portion of the chewing cycle is the area entering and leaving the intercuspal position where gliding contacts occur. Maximal chewing capability will likely occur when the chewing pattern follows the dental anatomy unique to the individual. The chewing cycle appears to increase the lateral component of its movement when increased chewing efficiency is required. These situations include increased hardness or the size of bolus, the position of the bolus and the results of the proceeding chewing stroke. The chewing pattern for any one cycle is influenced by a number of factors, thus it is not surprising that the question of the ideal chewing pattern remains unresolved.

    Anaesthetic induction time for tracheal intubation using sevoflurane or halothane in children (1998)
    Oxford : Blackwell Science Ltd

    Topics: Medicine
    Notes: The current study was designed to determine the anaesthetic induction time required for tracheal intubation (TimeEI) with equipotent inspired concentrations of 5% sevoflurane and 2.5% halothane in oxygen. TimeEI that prevents 50% and 95% of patients from coughing and gross purposeful muscular movements after intubation was defined as TimeEI50 and TimeEI95, respectively. Thirty-six patients aged 1–7 years were enrolled in the study. Anaesthesia was induced via mask and when TimeEI attained a predetermined value, intubation was performed using an uncuffed tube. Each TimeEI at which tracheal intubation was attempted was predetermined according to the up-and-down method. When intubation was accomplished without gross purposeful muscular movements, it was considered a smooth intubation. Determination with this method revealed that TimeEI50 and TimeEI95 for the sevoflurane/halothane groups were 147/214 s and 194/255 s, respectively. In conclusion, it is possible to determine TimeEI using an inspired sevoflurane concentration of 5% and halothane 2.5% in oxygen. The technique with 5% sevoflurane seems more practical for paediatric anaesthesia induction in busy clinical situations.

    Differential regulation of two myo-inositol transporter genes of Saccharomyces cerevisiae (1993)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: We previously isolated two distinct Saccharomyces cerevisiae myo-inositol transporter genes, ITR1 and ITR2 (Nikawa et al., 1991). Here, we studied the regulation of their expression by measuring steady-state mRNA levels and β-galactosidase activities of lacZ fusion genes under different conditions. The results show that the expression of the two ITR genes is differently regulated: ITR1 was repressed by inositol and choline whereas ITR2 was constitutive. Deletion analysis of the ITR1 upstream region and comparison with the upstream regions of other genes involved in phospholipid synthesis indicate that the octamer sequence 5′-TTCACATG-3′ is important for the expression and inositol/choline regulation of the ITR1 gene.

    Myxoglobulosis in an extravasation mucocele of the lower lip (1997)

    Notes: A case of extravasation mucocele showing an unusual intraluminal globular organization of the mucous content is described. The cystic lesion was obtained from the lower lip of a 10-year-old Japanese girl and presented as a painless swelling of 1 year duration. Histologically. the cyst cavity was filled with round globules and encapsulated by a granulation tissue wall devoid of a lining epithelium. To our knowledge, this peculiar histological pattern has not been previously described in an oral mucocele. Clinicopathological features of ‘myxoglobulosis of the appendix’, a morphological variant of appendiceal mucocele, appear to be related to the present case.
