Abstract
Due to the current COVID-19 pandemic there is a need for a rapid increase in intensive care and ventilation capacities. Delivery times for additional intensive care respirators are currently not foreseeable. An option to increase ventilation capacities not only for COVID-19, but for all patients requiring mechanical ventilation is to use home respirators. Home respirators are turbine respirators, so they can usually be operated without high-pressure oxygen connections and can therefore also be used in areas outside the classical intensive care medical infrastructure. Due to their limited technical features, home respirators are not suitable for the treatment of severely affected patients but can be used for weaning after respiratory improvement, which means that intensive care respirators are available again more quickly. Respiratory therapists are specially trained nurses or therapists in the field of out of hospital ventilation and can independently use home ventilation respirators, for example for weaning in the intensive care unit. Thus, they relieve intensive care nursing staff in the pandemic. Due to the COVID-19 pandemic medical students from the Oldenburg University are currently being trained in operating home respirators to provide basic support in the hospital if necessary.

Abstract
Temporally modulated electron beams have a wide array of applications ranging from the generation of coherently enhanced electromagnetic radiation to the resonant excitation of electromagnetic wakefields in advanced-accelerator concepts. Likewise producing low-energy ultrashort microbunches could be useful for ultrafast electron diffraction and new accelerator-based light-source concepts. In this Letter we propose and experimentally demonstrate a passive microbunching technique capable of forming a picosecond bunch train at ∼6 MeV. The method relies on the excitation of electromagnetic wakefields as the beam propagates through a dielectric-lined waveguide. Owing to the nonultrarelativistic nature of the beam, the induced energy modulation eventually converts into a density modulation as the beam travels in a following free-space drift. The modulated beam is further accelerated to ∼20 MeV while preserving the imparted density modulation.

Abstract
On the basis of the clinical studies in patients with coronary artery disease (CAD) presenting an increased percentage of activated platelets, we hypothesized that hemocompatibility testing utilizing platelets from healthy individuals may result in an underestimation of the materials' thrombogenicity. Therefore, we investigated the interaction of polymer-based biomaterials with platelets from CAD patients in comparison to platelets from apparently healthy individuals. In vitro static thrombogenicity tests revealed that adherent platelet densities and total platelet covered areas were significantly increased for the low (polydimethylsiloxane, PDMS) and medium (Collagen) thrombogenic surfaces in the CAD group compared to the healthy subjects group. The area per single platelet-indicating the spreading and activation of the platelets-was markedly increased on PDMS treated with PRP from CAD subjects. This could not be observed for collagen or polytetrafluoroethylene (PTFE). For the latter material, platelet adhesion and surface coverage did not differ between the two groups. Irrespective of the substrate, the variability of these parameters was increased for CAD patients compared to healthy subjects. This indicates a higher reactivity of platelets from CAD patients compared to the healthy individuals. Our results revealed, for the first time, that utilizing platelets from apparently healthy donors bears the risk of underestimating the thrombogenicity of polymer-based biomaterials.

Abstract
Breastfeeding is widely acknowledged to be the best and most complete form of nutrition for healthy infants born at term and is associated with numerous benefits in terms of infants' health, growth, immunity and development. However, breastfeeding problems often result in early weaning. Standardized treatment recommendations for breastfeeding-related diseases are necessary to optimize the care offered to breastfeeding women. Evidence and consensus based guidelines for the treatment of puerperal mastitis, sore nipples, engorgement and blocked ducts were developed on the initiative of the National Breastfeeding Committee. These guidelines were developed in accordance with the criteria set up by the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF), the Association of Scientific Medical Societies in Germany. The recommendations were drawn up by an interdisciplinary group of experts and were based on a systematic search and evaluation of the literature but also took clinical experience into account. Additionally good clinical practice (GCP) in terms of expert opinion was formulated in cases where scientific investigations could not be performed or were not aimed for. This article presents a summary of the recommendations of the S3-guidelines.

Abstract
In supension cultured tobacco cells only blue light induces and maintains chlorophyll synthesis if the liquid nutrient medium is supplemented with sucrose. The yield per gram fresh weight is closely correlated with the energy fluence rate of blue light, but not with the initial amount of sucrose added to the medium (3-12 g/l). The uptake of sucrose by the cells proceeds with a constant rate over the growth period independently of the initial amount leading within 10-25 days to sucrose-free media. Under these conditions the cells continue to synthesize chlorophyll for about 10 days. This limitation is overcome by adding sucrose to the medium at equal time intervals thus establishing a constant sugar level beyond the growth period. In contrast, glucose as carbon source cannot adequately replace sucrose in inducing and maintaining blue light-induced chlorophyll synthesis. Depending on the initial amount (3-10 g/l) this sugar is rapidly disappearing from the medium within 1-5 days after inoculation of the cells. It apparently serves as a preferential source of energy and carbon skeletons thus suppressing chlorophyll synthesis. On the other hand, glucose combined with sucrose in the medium brings about the characteristic induction and accumulation of chlorophyll in blue light which is observed with sucrose as the sole carbon source.
