    Exponential Distribution of Locomotion Activity in Cell Cultures

    In vitro velocities of several cell types have been measured using computer controlled video microscopy, which allowed to record the cells' trajectories over several days. On the basis of our large data sets we show that the locomotion activity displays a universal exponential distribution. Thus, motion resulting from complex cellular processes can be well described by an unexpected, but very simple distribution function. A simple phenomenological model based on the interaction of various cellular processes and finite ATP production rate is proposed to explain these experimental results.Comment: 4 pages, 3 figure

    Kardiale CT beim akuten Koronarsyndrom

    Full text link
    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome. Zusammenfassung Die kardiale CT wird aufgrund des rasanten technischen Fortschritts der letzten Jahre zunehmend in klinische Algorithmen integriert. Dabei gilt aufgrund der bestehenden wissenschaftlichen Evidenz der Einsatz der kardialen CT bei Patienten mit Verdacht auf ein akutes Koronarsyndrom als besonders vielversprechend. Die Durchführung der kardialen CT erfordert spezifische Kenntnisse über die Untersuchungsprotokolle, adäquate Patientenvorbereitung und die diagnostischen Befunde, welche auch nichtkardiale Nebenbefunde umfasst. Der vorliegende Artikel gibt einen Überblick über die spezifischen Aspekte zum Einsatz der kardialen CT bei Patienten mit Verdacht auf ein akutes Koronarsyndrom
