    Abstract The development of highly productive, selective and stable propane dehydrogenation catalysts for propene production is strategic due to the increasing need for propene and the availability of shale gas, an abundant source of light alkanes. In that context, the combination of surface organometallic chemistry (SOMC) and a thermolytic molecular precursor (TMP) approach is used to prepare bimetallic subnanometric and narrowly distributed Pt-Zn alloyed particles supported on silica

    Abstract Neurodegenerative Erkrankungen des zentral-motorischen Systems führen oft nur zu geringen (aber funktionell bedeutsamen) Veränderungen an unterschiedlichen Teilen des Hirnparenchyms. Die MRT ist die sensitivste Methode zur Darstellung solcher Veränderungen. In diesem Beitrag werden verschiedene neurodegenerative Erkrankungen mit ihren wichtigsten klinischen Merkmalen und MRT-Befunden vorgestellt. Differenzialdiagnostisch nützliche Kriterien werden angegeben.

    Abstract A family of Pt(II) complexes bearing monoanionic C^N^N ligands as luminophoric units as well as a set of monodentate ligands derived from allenylidene and carbene species were synthesized and characterized in terms of structure and photophysical properties. In addition, we present the extraordinary molecular structure of a phosphorescent complex carrying an allenylidene ligand. Depending on the co-ligand, an effect can be observed in the photoluminescence lifetimes and quantum yields as well as in the radiative and radiation less deactivation rate constants. Their correlation with the substitution pattern was analyzed by comparing the photoluminescence in fluid solution at room temperature and in frozen glassy matrices at 77 K. Moreover, in order to gain a deeper understanding of the electronic states responsible for the optical properties, density functional theory calculations were performed. Finally, the cytotoxicity of the complexes was evaluated

    Title translation Endovascular therapy of stroke.
    Abstract Standard therapy of acute ischaemic stroke during the first three hours after symptom onset is intravenous thrombolysis. When contraindications exist, an endovascular approach might be possible. Intraarterial administration of thrombolytic drugs is the most common way. Additionally, there is an increasing use of mechanical tools that are expected to be faster and more effective. Three principles of mechanical thrombolysis are known: aspiration, extraction and fracturing of the thrombus. Different tools were tested clinically and some demonstrated its high efficiency. Larger studies are needed to compare those tools. Apart from recanalization of a cerebral vessel occlusion implantation of a stent might be necessary for prophylaxis of recurrent stroke.
