Evaluation of Bioelectrical Impedance Spectroscopy for the Assessment of Extracellular Body Water

This study evaluates bioelectrical impedance spectroscopy (BIS) measurements to detect body fluid status. The multifrequency impedance measurements were performed in five female pigs. Animals were connected to an extracorporeal membrane oxygenation device during a lung disease experiment and fluid balance was recorded. Every 15 min the amount of fluid infusion and the weight of the urine drainage bag was recorded. From the fluid intake and output, the fluid balance was calculated. These data were compared with values calculated from a mathematical model, based on the extracellular tissue resistance and the Hanai Mixture theory. The extracellular tissue resistance was also measured with BIS. These experimental results strongly support the feasibility and clinical value of BIS for in vivo assessment of the hydration status

Organizing Online Events

This is a compilation of over 100 slides which were presented in different block courses on Organizing Online Events that were attended by colleagues and members of The Africa Multiple Cluster of Excellence at the University of Bayreuth. Each of them was tailored for different events and attendees – from new student assistants to professors of partner institutions. We used Zoom Meetings and Zoom Webinars, but also administrative platforms and OBS and Restream for streaming onto other platforms. Most courses were structured into eight modules, comprising Basics, Installation of Zoom Webinars/Meetings, Recording, Streaming, Mixed Formats, (internal) Administrative Tasks, Problem Management, and After the Event. Some modules are designed for beginners, some for experienced colleagues

DNA-Controlled Excitonic Switches

Fluorescence resonance energy transfer (FRET) is a promising means of enabling information processing in nanoscale devices, but dynamic control over exciton pathways is required. Here, we demonstrate the operation of two complementary switches consisting of diffusive FRET transmission lines in which exciton flow is controlled by DNA. Repeatable switching is accomplished by the removal or addition of fluorophores through toehold-mediated strand invasion. In principle, these switches can be networked to implement any Boolean function
