Background: The high incidence of stroke recurrence necessitates effective post-stroke care. This study investigates the effectiveness of a case management-based post-stroke care program in patients with acute stroke and TIA.

Methods: In this prospective cohort study, patients with TIA, ischemic stroke or intracerebral hemorrhage were enrolled into a 12-month case management-based program (SOS-Care) along with conventional care.

The recently observed FLASH effect describes the observation of normal tissue protection by ultra-high dose rates (UHDR), or dose delivery in a fraction of a second, at similar tumor-killing efficacy of conventional dose delivery and promises great benefits for radiotherapy patients. Dedicated studies are now necessary to define a robust set of dose application parameters for FLASH radiotherapy and to identify underlying mechanisms. These studies require particle accelerators with variable temporal dose application characteristics for numerous radiation qualities, equipped for preclinical radiobiological research.

Article Synopsis
  • In Saxony, Germany, detection of PVL-positive MRSA must be reported to health authorities, enabling the implementation of infection control measures.
  • An analysis of cases in 2019 showed that most patients had skin and soft-tissue infections, with many being young adults and a significant number having travel or migration histories.
  • Molecular testing identified various MRSA lineages, showing that household contacts often carried the same clone as the index cases, highlighting a close link in the spread of this infection.

We present a method extending scanning third-order correlator temporal pulse evolution measurement capabilities of high power short pulse lasers to spectral sensitivity within the spectral range exploited by typical chirped pulse amplification systems. Modelling of the spectral response achieved by angle tuning of the third harmonic generating crystal is applied and experimentally validated. Exemplary measurements of spectrally resolved pulse contrast of a Petawatt laser frontend illustrate the importance of full bandwidth coverage for the interpretation of relativistic laser target interaction in particular for the case of solid targets.

Semiconducting transition metal oxides such as [Formula: see text] are promising photo(electro)catalysts for solar water splitting and photoreduction of [Formula: see text] as well as for antibacterial, self-, water and air-cleaning coatings and admixtures in paints, building materials, on window glass or medical devices. In photoelectrocatalytic applications [Formula: see text] is usually used as photoanode only catalyzing the oxidation reaction. In coatings and admixtures [Formula: see text] works as heterogeneous catalyst and has to catalyze a complete redox cycle.
