  abstract  = {Recently, we have suggested a nanomechanical model for dissipative loss in filled elastomer networks in the context of the Payne effect. The mechanism is based on a total interfiller particle force exhibiting an intermittent loop, due to the combination of short-range repulsion and dispersion forces with a long-range elastic attraction. The sum of these forces leads, under external strain, to a spontaneous instability of "bonds" between the aggregates in a filler network and attendant energy dissipation. Here, we use molecular dynamics simulations to obtain chemically realistic forces between surface modified silica particles. The latter are combined with the above model to estimate the loss modulus and the low strain storage modulus in elastomers containing the aforementioned filler-compatibilizer systems. The model is compared to experimental dynamic moduli of silica filled rubbers. We find good agreement between the model predictions and the experiments as function of the compatibilizer's molecular structure and its bulk concentration.},

  abstract  = {Bei der Verarbeitung nachwachsender Rohstoffe entsteht aus Cellulose oder St{\"a}rke u. a. das wichtige Produkt Glucose. Diese niedermolekulare Kohlenhydratquelle wird {\"u}blicherweise als Substrat f{\"u}r biotechnologische und chemische Synthesen verwendet. Ein wirtschaftlich interessantes Oxidationsprodukt der Glucose ist Glucons{\"a}ure, die beispielsweise als Lebensmittelzusatzstoff (E 574), in der Medizin und Metallindustrie Verwendung findet. Die Umsetzung des Monosaccharids zu Glucons{\"a}ure erfolgt entweder durch mikrobielle Fermentation oder der Oxidation an heterogenen Katalysatoren. Die Zielsetzung der Studie ist die Untersuchung der Glucoseoxidation an magnetisierbaren Gold-Nanopartikeln unter nachfolgender Bypass-Separation des Katalysators mittels einer neuen Mini-HGMS-Einheit (Hochgradient-Magnetseparation). Dieser Filtertyp erm{\"o}glicht die selektive Trennung magnetischer Partikel aus Suspensionen mit hohem Feststoffgehalt oder Viskosit{\"a}t. Erste Ergebnisse zeigen eine Beladungskapazit{\"a}t des selbstkonstruierten Mini-HGMS von 550 mg goldbeschichteter magnetisierbarer Nanopartikel. Die Oxidation erfolgt bei einem pH-Wertvon 9, bei 40 °C und mit 100 mM Glucose in einem begasten R{\"u}hrkesselreaktor. Das System soll zuk{\"u}nftig zum Katalysatorrecycling von hochviskosen und Feststoffbelasteten Produktstr{\"o}men aus Bioraffinerien eingesetzt werden.},

  abstract  = {Clostridium propionicum is the only organism known to ferment β-alanine, a constituent of coenzyme A (CoA) and the phosphopantetheinyl prosthetic group of holo-acyl carrier protein. The first step in the fermentation is a CoA-transfer to β-alanine. Subsequently, the resulting β-alanyl-CoA is deaminated by the enzyme β-alanyl-CoA:ammonia lyase (Acl) to reversibly form ammonia and acrylyl-CoA. We have determined the crystal structure of Acl in its apo-form at a resolution of 0.97 {\AA} as well as in complex with CoA at a resolution of 1.59 {\AA}. The structures reveal that the enyzme belongs to a superfamily of proteins exhibiting a so called "hot dog fold" which is characterized by a five-stranded antiparallel β-sheet with a long α-helix packed against it. The functional unit of all "hot dog fold" proteins is a homodimer containing two equivalent substrate binding sites which are established by the dimer interface. In the case of Acl, three functional dimers combine to a homohexamer strongly resembling the homohexamer formed by YciA-like acyl-CoA thioesterases. Here, we propose an enzymatic mechanism based on the crystal structure of the Acl·CoA complex and molecular docking. Proteins 2014; 82:2041-2053. © 2014 Wiley Periodicals, Inc.},

In 2012 wurden in Deutschland 33 Millionen Tonnen (Heugewicht) Gras auf 4,82 Millionen Hektar Ackerland produziert, davon wurden 60,5 \% siliert.

  abstract  = {1. Drug metabolizing enzymes and transporters play important roles in the absorption, metabolism, tissue distribution and excretion of various compounds and their metabolites and thus can significantly affect their efficacy and safety. Furthermore, they can be involved in drug-drug interactions which can result in adverse responses, life-threatening toxicity or impaired efficacy. Significant species differences in the interaction of compounds with drug metabolizing enzymes and transporters have been described. 2. In order to overcome the limitation of animal models in accurately predicting human responses, a large variety of mouse models humanized for drug metabolizing enzymes and to a lesser extent drug transporters have been created. 3. This review summarizes the literature describing these mouse models and their key applications in studying the role of drug metabolizing enzymes and transporters in drug bioavailability, tissue distribution, clearance and drug-drug interactions as well as in human metabolite testing and risk assessment. 4. Though such humanized mouse models have certain limitations, there is great potential for their use in basic research and for testing and development of new medicines. These limitations and future potentials will be discussed.},
