    Description: Influenza viruses are highly contagious. Medical personnel are at risk of occupational exposure to influenza. Data on dental healthcare workers (DHCWs) immunization status has not been published. We conducted a cross-sectional survey of DHCWs and dental students at a German dental university hospital. Surveys, completed between October 2010 and March 2011, focused on reasons of DHCWs for accepting or declining the influenza vaccination. Furthermore, we characterized attitudes towards influenza infection due to the emergence of the H1N1/2009. Compliance rates with the influenza vaccination among DHCWs were low (31.6%). The main reason for not getting vaccinated against the pandemic influenza A/H1N1 virus in the 2009/2010 season was the objection to the AS03-adjuvants (48.5%). Of the DHCWs surveyed, 30.6% (74/242) cited that the H1N1/2009 pandemic influenced their attitudes towards vaccination in general. Our findings confirm the importance of a comprehensive approach to the influenza vaccination, ensuring that DHCWs are correctly informed about the vaccine and that it is convenient to receive it. It could be shown that an immunization campaign at the workplace seems to be capable of improving vaccination rates, one-third of the vaccinees have been vaccinated for the first time.

    Description: Zielsetzung: Die Evaluation vier verschiedener Funktionsprinzipien (Schieb-Drehregler, Pedal-Schiebregler, Universal-Pedalregler und Pedalregler) von zahnärztlichen Fußanlassern im Hinblick auf die Fußdruckverteilung bei ihrer Bedienung. Material und Methode: An dieser Studie haben 63 Probanden (31 w, 32 m) teilgenommen. Für die Messung der Druckverteilung des Arbeits- und Standfußes bei Betätigung des Fußanlassers wird das Innenschuhmesssystem der Firma medilogic (Schöne feld, Deutschland) eingesetzt. Gemessen wird die Druckverteilung beider Füße bei Regulierung der Drehzahl. Für die statistische Auswertung des maximalen und mittleren Drucks der sechs Zonen eines Fußes wird der Friedman-Test eingesetzt. Des Weiteren wurde von den Probanden ein Fragebogen ausgefüllt zur Beurteilung bzw. Benotung der Fußanlasser und der täglich bedienten Behandlungseinheit. Ergebnisse: Je nach Funktionsprinzip kommt es zu signifikanten Unterschieden am Arbeits- und Standbein bezüglich des mittleren und maximalen Fußdrucks des gesamten Fußes. Die Fußdruckbelastung innerhalb der 6 Fußzonen ist durch das Funktionsprinzip relativ bestimmt. Wobei die Pedalfunktion die höchsten Druckwerte in der Fersenregion hervorruft. Im Hinblick auf die Benotung der Funktionsprinzipien von sehr gut bis schlecht hat der Schieb-Drehregler die beste Note gefolgt vom Pedal-Schiebregler, dem Universal-Pedalregler und dem Pedalregler. Schlussfolgerung: Bei der Betrachtung der vier unterschiedlichen Funktionsprinzipen der zahnärztlichen Fußanlasser erfolgt eine Mehrbelastung bei der Flexions-/Extensionsbewegung des Arbeitsbeins bei Betätigung des Universal-Pedalreglers, des Pedalreglers und des kombinierten Pedal-Schiebreglers. Im Gegenzug rufen der Universal-Pedalregler und der Pedalregler eine geringere Belastung des Standbeins durch muskuläre Ausgleichsfunktionen im Sinne einer Gewichtsverlagerung hervor. Hinsichtlich der Ergebnisse bezugnehmend auf die Bewertungen der Funktionsprinzipen ist festzustellen, dass der am häufigsten verwendete Fußanlasser bezüglich der Bedienbarkeit überwiegend als unangenehm benotet wurde. Aim: Evaluation of foot pressure distribution during the operation of four dental foot controller, each with its own working principle: (universal-pedal controller (A-dec), combined sliding-pedal controller (Kavo), pedal controller (Sirona), sliding wheel controller (XO CARE)). Material and Methods: 63 subjects (31 f, 32 m) participated in this study. The in-shoe measuring system from medilogic (Schönefeld, Germany) was used to record the pressure distribution of the working and the supporting leg during the operation of the foot controller. The foot pressure distribution of both feet detected the regulation of the speed. For the statistical evaluation of the maximum and average pressure of the six zones of the foot the Friedman-test and a Bonferroni-Holm correction were used. Having finished the test, the subjects were asked to fill out a questionnaire to rank the operating principles of each foot controller. Results: There are significant differences among the medium and maximum pressure values of the working and supporting leg. The foot pressure load (among the six measured zones) is quite determined by the foot controllers operating principles. The highest pressure values occurred on the heel using a foot controller which has the pedal principle. Regarding the rating of the working principles of the foot controllers (1 best — 4 worst), the sliding wheel controller ranked best followed by the combined sliding-pedal controller, the universal-pedal controller and the pedal controller. Conclusion: There is an increased pressure load on the flexion and extension movement of the working leg during operating the universal-pedal controller, the pedal controller and the combined sliding-pedal controller. In turn, the universal-pedal controller and the pedal controller evoke a reduction of the load on the supporting leg by muscular compensation functions in terms of shifting the weight. Thus, accustomed work sequences have a negative impact on the movement system and should therefore be included in a manual therapeutic examination and therapy.

    Description: In the present contribution, the strategy of atomic force microscope mapping of periodical rough surfaces is combined with an extension of the polyhedral model. Atomic force microscope images are numerically interpolated, applying non‐uniform rational B‐splines, which also have the advantage that simultaneously to the interpolation, they provide the normals at any point on the rough surfaces. Compared with the polyhedral model, in the present scheme, any rough surface is accurately well approximated by a finite set of almost infinitesimal planes, which are all oriented in accordance with the normals obtained, while non‐uniform rational B‐splines interpolate the surface. In this view, the Beer–Lambert law is straightforwardly applied to compute all local (almost pointwise resolved) contributions to the photoelectron intensity on the analyser site. The proposed numerical scheme is validated in case of Si samples possessing either arbitrary rough, one‐ or two‐dimensional periodic structures on the analysed surfaces. In this manner, it is shown that the computed angle‐resolved XPS well agree with the experimental ones. Copyright © 2012 John Wiley & Sons, Ltd.

    Description: The quaternary structure and functional properties of synaptophysin, a major integral membrane protein of small presynaptic vesicles, were investigated. Cross-linking and sedimentation studies indicate that synaptophysin is a hexameric homo-oligomer, which in electron micrographs exhibits structural features common to channel-forming proteins. On reconstitution into planar lipid bilayers, purified synaptophysin displays voltage-sensitive channel activity with an average conductance of about 150 picosiemens. Because specific channels and fusion pores have been implicated in vesicular uptake and release of secretory compounds, synaptophysin may have a role in these processes.
