    Notizen: 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.

    Controlled spontaneous emissions from current-driven semiconductor microcavity triodes (1999)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 74 (1999), S. 1278-1280

    ISSN: 1077-3118

    Thema: Physik
    Notizen: 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.

    ANTIARRHYTHMIC PROPERTIES OF 5-(3-TERT-BUTYLAMINO-2-HYDROXY)PROPOXY-3,4-DIHYDRO-CARBOSTYRIL HYDROCHLORIDE (OPC- 1085), A NEWLY SYNTHESIZED, POTENT β-ADRENORECEPTOR ANTAGONIST (1977)

    Notizen: 1. The antiarrhythmic properties of 5–(3-tert-butylarnino-2-hydroxy)propoxy-3,4-dihydrocarbostyril hydrochloride (OPC-1085) were compared with those of propranolol and pindolol using various kinds of preparations for experimental arrhythmia in dogs.2. Although OPC-1085 was the most potent drug to antagonize adrenaline-induced arrhythmia in animals anaesthetized with either pentobarbitone sodium or halothane, it was scarcely effective on ouabain-induced arrhythmia in pentobarbitone sodium anaesthetized animals.3. When these compounds were administered intravenously to conscious dogs 24 h after two-stage ligation of the anterior descending artery, ectopic ventricular beats of coronary ligation-induced arrhythmia were reduced while regular sinus beats were simultaneously increased.4. OPC-1085 was very effective on aconitine-induced arrhythmia in dogs anaesthetized with pentobarbitone sodium. The effective dose was similar to that of propranolol but about fifteen times less than that of pindolol.5. It is concluded that different potencies among these β-adrenoreceptor antagonists against various kinds of experimental arrhythmias cannot be simply deduced from any one of the following properties; β-adrenoreceptor antagonism, intrinsic myocardial stimulation, local anaesthetic and so-called quinidine-like effects.

    Anaesthetic induction time for tracheal intubation using sevoflurane or halothane in children (1998)
    Oxford : Blackwell Science Ltd
    Anaesthesia 53 (1998), S. 0 
    Details

    Thema: Medizin
    Notizen: 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
    Molecular microbiology 10 (1993), S. 0

    Thema: Biologie , Medizin
    Notizen: 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)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral pathology & medicine 26 (1997), S. 0

    Thema: Medizin
    Notizen: 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.

    Scanning electron microscopic study of Warthin's tumor (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral pathology & medicine 16 (1987), S. 0

    Thema: Medizin
    Notizen: Three cases of Warthin's tumors were studied with a scanning electron microscope. The free surface of the epithelium was composed mainly of round or ovoid dome-like structures bearing microvilli and apocrine protrusions. Ciliated epithelial cells were detected in 2 of the tumors. The tumor epithelium encircled various amounts of cellular debris resembling degenerate lymphoid cells. A few tiny cystic spaces were also found. Within the lymphoid stroma, tightly packed lymphocytes, a meshwork of reticulum cells and medullary cord-like structures were observed. Our findings support the concept that Warthin's tumors develop from heterotopic salivary gland ducts within pre-existing lymph nodes.

    Tooth contacts at the mandibular retruded position, influence of operator's skill on bite registration (2003)

    Notizen: summary  Occlusal conditions at the retruded contact position (RCP) have been thought to be among the aetiological factors for temporomandibular disorders. However, the role of these occlusal factors still remain unclear. The purpose of a series of studies was to investigate the locations of RCP contacts and to discuss their implication by the authors. In the study reported here, the influence of the operator's skill on bite registration was surveyed. Eighty-six dental students were selected as subjects. One specialist in prosthetic dentistry moved the subject's mandible up and down while guiding it gently backward until it rotated on its retruded axis. Once the initial tooth contacts were established, the operator checked them by using a thin articulating paper (direct method). On the other hand, six younger operators following precise instruction from the specialist about the technique of jaw guidance examined each of the subjects for location of RCP contacts using the indirect method. Silicone-based impression material was used for bite registration while the subject kept the jaw at this contact position (indirect method). Wilcoxon signed rank test was applied to evaluate differences between the expert operator and six younger operators regarding locations of RCP contacts. Results from the expert operator (direct method) showed that tooth contact at the first premolar was most frequently observed and the number of subjects who possessed unilateral tooth contacts was more than that with bilateral tooth contacts. On the other hand, in the case of the indirect method performed by younger operators, tooth contact patterns significantly differed from those of the direct method.
