Migration von /sw vom AFS ins DCE/DFS

/sw ist eine verteilte Softwarebereitstellung mit dem Ziel, jedem Benutzer Software zentral zur Verfügung zu stellen, ohne daß er sich darum kümmern muß, woher er seine Software bekommt. Für eine Außenstehenden ergibt sich somit das Bild eines großen Softwarepools, aus dem er sich fertig installierte Software für seine Plattform herunterladen kann. Voraussetzung dafür ist, daß ein Benuzter an seiner Workstation über AFS (Andrew File System), DFS (Distributed File System) oder ftp verfügt. Zur Zeit werden vom /sw für 18 verschiedenen Unix-Plattformen 594 Programme in 1024 verschiedenen Installationen angeboten. Die meisten Architekturen vom /sw liegen im AFS, bis auf die Architekturen DEC ALPHA, IRIX 4.0 und Linux, die im NFS liegen. In Zukunft wird es für die gesamte /sw Software nur noch eine Quelle geben, das DFS. Mit der Migration von /sw aus dem AFS ins DFS entfällt dann die Trennung von /sw in einen AFS-Teil und einem NFS-Teil und damit auch der AFS/NFS-Translators, der recht unstabil läuft. Die gesamte Software von /sw wurde aus dem AFS bzw. NFS ins DFS migriert, so daß für alle vom /sw unterstützten Architekturen nur noch eine Quelle zur Verfügung steht, die Stuttgarter DCE-Zelle. Jeder AFS-Klient hat über den AFS/DFS-Translator Zugriff auf /sw und für die NFS-Klienten wird das /sw-Fi-lesystem exportiert, so daß jeder NFS-Klient die Möglichkeit hat das DFS-Filesystem /sw zu mounten. Eine Workstation kann sowohl AFS- als auch DCE/DFS-Klient sein

Métastase ovarienne et adénocarcinome pulmonaire :observation d'un cas clinique = Ovarian metastasis and lung adenocarcinoma: A case report

Ovarian metastasis as first dissemination site of a lung adenocarcinoma has not been described in the literature. We report the case of a 61-year-old woman who had a pneumectomy for a centrally located lung adenocarcinoma, which was discovered on a routine chest X-Ray. During the follow-up, a Positron Emission Tomography (PET)-Scan showed a hypercaptation in the pelvic region. Abdominal CT-scan confirmed the presence of a mass which was compatible with a primary ovarian tumor. The patient underwent a hysterectomy and bilateral salpingo-oophorectomy. Pathology reported an adenocarcinoma. Immunohistochemical staining revealed cells expression for Thyroid Transcription Factor 1 (TTF-1), cytokeratin 7 (CK-7) and focally cytokeratin 20 (CK-20). Clinical course, pathological and immunohistochemical data concluded to the diagnosis of ovarian metastasis of the lung adenocarcinoma. In conclusion, in the differential diagnosis of an ovarian metastasis, clinicians should not forget the lung as primary site since epidemiologic data of lung cancer in women show progressive incidence. © 2005 Elsevier SAS.

Audiovisual aid viewing immediately before pediatric induction moderates the accompanying parents' anxiety

Parents accompanying their child during induction of anesthesia experience stress. The impact of audiovisual aid (AVA) on parental state anxiety and assessment of the child's anxiety at induction have been studied previously but need closer scrutiny. One hundred and twenty parents whose children were scheduled for day-care surgery entered this randomized, controlled study. The intervention group (n = 60) was exposed to an AVA in the holding area. Parental anxiety was measured with the Spielberger State-Trait Anxiety Inventory and the Amsterdam Preoperative Anxiety and Information Scale (APAIS) at three time points: (i) on admission [T1]; (ii) in the holding area just before entering the operating theater [T2]; and (iii) after leaving [T3]. Additionally, at [T3], both parent and attending anesthetist evaluated the child's anxiety using a visual analogue scale. The anesthetist also filled out the Induction Compliance Checklist. On the state anxiety subscale, APAIS parental anxiety at T2 (P = 0.015) and T3 (P = 0.009) was lower in the AVA intervention group than in the control group. After induction, the child's anxiety rating by the anesthetist was significantly lower than by the parent, in both intervention and control groups. Preoperative AVA shown to parents immediately before induction moderates the increase in anxiety associated with the anesthetic induction of their child. Present results suggest that behavioral characteristics seem better predictors of child's anxiety during induction than anxiety ratings per se and that anesthetists are better than parents in predicting child's anxiety during inductio

High-accuracy absolute distance measurement with a mode-resolved optical frequency comb

Optical interferometry enables highly accurate non-contact displacement measurement. The optical phase ambiguity needs to be resolved for absolute distance ranging. In controlled laboratory conditions and for short distances it is possible to track a non-interrupted displacement from a reference position to a remote target. With large distances covered in field applications this may not be feasible, e.g. in structure monitoring, large scale industrial manufacturing or aerospace navigation and attitude control. We use an optical frequency comb source to explore absolute distance measurement by means of a combined spectral and multi-wavelength homodyne interferometry. This relaxes the absolute distance ambiguity to a few tens of centimeters, covered by simpler electronic distance meters, while maintaining highly accurate optical phase measuring capability. A virtually imaged phased array spectrometer records a spatially dispersed interferogram in a single exposure and allows for resolving the modes of our near infrared comb source with 1 GHz mode separation. This enables measurements with direct traceability of the atomic clock referenced comb source. We observed agreement within 500 nm in comparison with a commercial displacement interferometer for target distances up to 50 m. Furthermore, we report on current work toward applicability in less controlled conditions. A filter cavity decimates the comb source to an increased mode separation larger than 20 GHz. A simple grating spectrometer then allows to record mode-resolved interferograms.</p

Animal cell cultures: Risk Assessment and biosafety recommendations

During the last three decades, animal cell culturing hasbeen essential for biomedical research and biotechnologicalactivities in general. Along with this increasing importance,biosafety concerns have pointed to the risks of manipulatinganimal cell cultures for human health and the environment. Amaximal reduction of these risks necessitates a thorough riskassessment of the cell cultures used. It involves an evaluationof both the intrinsic properties of the cell culture, includingsubsequent properties acquired as a result of genetic modification,and the possibility that the cell culture may inadvertentlyor deliberately become contaminated with pathogens.The latter is a major hazard associated with the manipulationof animal cell cultures, as adventitious agents may be pathogenicand have a better capacity to survive in unfavorableconditions. Consequently, most of the containment measuresprimarily aim at protecting cells from adventitious contamination.Therefore, a comprehensive evaluation of the risks encounteredduring the handling of cell cultures should includeconsiderations regarding the type of manipulation as well. Asa rule, cell cultures known to harbor an infectious etiologicagent should be manipulated in compliance with containmentmeasures recommended for the etiologic agent. With the exceptionof very well-characterized cell cultures for which theuse of a type II biosafety cabinet depends on the origin of thecells, work with cell cultures from human or primate originshould generally and minimally be performed under containmentlevel 2 using a type II biosafety cabinet. In every case,containment measures should minimize adventitious contaminationof the cell cultures and offer a maximal protection ofhuman health and the environment.</p

A Visual Analog Scale to assess anxiety in children during anesthesia induction (VAS-I): Results supporting its validity in a sample of day care surgery patients

The modified Yale Preoperative Anxiety Scale is widely used to assess children's anxiety during induction of anesthesia, but requires training and its administration is time-consuming. A Visual Analog Scale, in contrast, requires no training, is easy-to-use and quickly completed. The aim of this study was to evaluate a Visual Analog Scale as a tool to assess anxiety during induction of anesthesia and to determine cut-offs to distinguish between anxious and nonanxious children. Four hundred and one children (1.5-16 years) scheduled for daytime surgery were included. Children's anxiety during induction was rated by parents and anesthesiologists on a Visual Analog Scale and by a trained observer on the modified Yale Preoperative Anxiety Scale. Psychometric properties assessed were: (i) concurrent validity (correlations between parents' and anesthesiologists' Visual Analog Scale and modified Yale Preoperative Anxiety Scale scores); (ii) construct validity (differences between subgroups according to the children's age and the parents' anxiety as assessed by the State-Trait Anxiety Inventory); (iii) cross-informant agreement using Bland-Altman analysis; (iv) cut-offs to distinguish between anxious and nonanxious children (reference: modified Yale Preoperative Anxiety Scale ≥30). Correlations between parents' and anesthesiologists' Visual Analog Scale and modified Yale Preoperative Anxiety Scale scores were strong (0.68 and 0.73, respectively). Visual Analog Scale scores were higher for children ≤5 years compared to children aged ≥6. Visual Analog Scale scores of children of high-anxious parents were higher than those of low-anxious parents. The mean difference between parents' and anesthesiologists' Visual Analog Scale scores was 3.6, with 95% limits of agreement (-56.1 to 63.3). To classify anxious children, cut-offs for parents (≥37 mm) and anesthesiologists (≥30 mm) were established. The present data provide preliminary data for the validity of a Visual Analog Scale to assess children's anxiety during inductio
