P2X receptors in maintenance and differentiation of neural progenitor cells

Neural Regeneration Research 2014年第23期9卷 2040-2041页

作者： Henning ulrich Peter Illes Departamento de Bioquímica Instituto de Química Universidade de Sao Paulo Rudolf-Boehm-Institut für Pharmakologie und Toxikologie der Universitat Leipzig

Purinergic receptors are among the first cell surface receptors expressed during embryonic development （Burnstock and ulrich, 2011）. These are characterized based on their pharmacological properties of being activated by adenosine or purine/pyrimidine nucleotides as P1 and P2 receptors. P2 receptors are further classified by their structure as P2Y metabotropic and P2X ionotropic receptors.

Geochemical Stratigraphy and Microvertebrate Assemblage Sequences across the Silurian/Devonian Transition in South China

Acta Geologica Sinica(English Edition) 2011年第2期85卷 340-353页

Carbon isotope （δ13Corg） analyses of non-marine clastic rocks and neritic carbonates and black shales spanning the Silurian/Devonian transition are compared from two richly fossiliferous sequences in Qujing of East Yunnan and Zoige of Sichuan, South China. The two sections, Xishancun and Putonggou sections in South China, reveal positive δ13Corg shifts happening in the Upper Pridoli and Lower Devonian and reaching peak values as heavy as -25.2‰ （Xishancun） and -19.9‰（Putonggou） in the lowermost Lochkovian following the first occurrence of the thelodont Parathelodus and the conodont Icriodus woschmidti woschmidti （only in Putonggou Section and together with Protathyris-Lanceomyonia brachiopod fauna）. These results replicate a globally known positive shift in δ13Corg from the uppermost Silurian to the lowermost Devonian. The δ13Corg variations across the Silurian/Devonian Boundary （SDB） at the two sections in South China exhibit a shift in carbon isotopic composition similar to the detailed SDB curves from the borehole Klonk-1 drilled at top of the Klonk Global Standard Stratotype-Section and Point （GSSP） in the Prague Basin, Czech Republic. In addition, four microvertebrate assemblages, including the Liaojiaoshan, Xishancun, Yanglugou and Xiaputonggou assemblages, are recognized from the Silurian/Devonian transition exposed in the Xishancun and Putonggou sections, respectively. The results from both carbon isotope stratigraphy and microvertebrate assemblage sequences suggest that the SDB in South China is located at the base of the Xishancun Formation （between sample QX-20 and sample QX-21） in the Xishancun Section and the lower part of the Xiaputonggou Formation （between sample ZP-09 and sample ZP-10） in the Putonggou Section. The isotopic trend for organic carbon together with the changes of microvertebrate remains across the SDB can offer an approach to a potential correlation of the SDB from different sedimentary facies, which help to correlate the marine with no

Frontiers of Chemical Science and Engineering 2013年第1期7卷 1-8页

作者： J. ulrich P. Frohberg Center for Engineering Science Thermal Process Engineering Martin Luther University Halle-Wittenberg D-06099 Halle (Saale) Germany

This review discusses important research developments and arising challenges in the field of industrial crystallization with an emphasis on recent problems. The most relevant areas of research have been identified. These are the prediction of phase diagrams; the prediction of effects of impurities and additives; the design of fluid dynamics; the process control with process analytical technologies （PAT） tools; the polymorph and solvate screening; the stabilization of non-stable phases; and the product design. The potential of industrial crystallization in various areas is outlined and discussed with particular reference to the product quality, process design, and control. On this basis, possible future directions for research and development have been pointed out to highlight the importance of crystallization as an outstanding technique for separation, purification as well as for product design.

Molecular level simulations on multi-component systems --a morphology prediction method

引用

Frontiers of Chemical Science and Engineering 2013年第1期7卷 49-54页

作者： C. SCHMIDT J. ulrich Center for Engineering Science Thermal Process Engineering Martin Luther University Halle-Wittenberg D-06099 Halle (Saale) Germany

The crystal morphology grown from a solution composed of an organic solvent, solute and additive can be predicted reliably by a computational method. Modeling the supersaturated solution as liquid phase is achieved by employing commercial software. The molecular composition of this solution is a required input parameter. The face specific diffusion coefficient of the solid （crystal surface） and liquid （solution） system is determined using the molecular dynamics procedure. The obtained diffusion coefficient is related to the specific face growth rate via the attachment energy of the pure morphology. The significant improvements are achieved in the morphology prediction because the investigation on the face growth rates in a complex growth environment （as multi-component solutions with additives） can be carried out based on the diffusion coefficients.

赫尔德是18世纪德意志重要的思想家,在德意志等西方文学、哲学与其他相关领域享有重要地位。德国康斯坦茨大学盖尔教授是德国著名日耳曼学者,著作等身,长期从事德意志近现代文学研究,尤以在赫尔德研究领域贡献卓著。本文从流派概念出发,围绕赫尔德以及他同时代人,对盖尔教授进行访谈。因为德意志近代文学独具特色,盖尔教授反对用流派概念对这些作家进行标签化的简单划分。而赫尔德在这一独具特色的德意志近代文学中起了举足轻重的作用,对后来德意志文学以及文史哲发展影响深远。

Utilizing melt crystallization fundamentals in the development of a new tabletting technology

引用

Frontiers of Chemical Science and Engineering 2014年第3期8卷 346-352页

作者： Ahmed ABOUZEID Sandra PETERSEN Joachim ulrich Martin Luther University Halle-Wittenberg Center for Engineering Science Thermal Process Engineering D-06099 Halle Germany

Increasing production effeciency and lowering costs are some of the many advantages melt crystallization technology offers over the conventional methodology of tabletting. A normal tablet consists of a pure shell or a coat and a separate core constituting the pharmaceutical active ingredient. Great emphasis is put on the purity of the shell since its purpose is to solely protect and deliver the active ingredient to its target. Melt crystallization is a purification （separation） process. It is discussed here for its ability to produce coated tablets, by separating the ＂coating＂ material from the ＂to be coated＂ material coming from one molten mixture. Molten drops of lutrol-ibuprofen mixture are produced using the drop forming technique. The subsequent analysis involves proving and quantifying the phase separation （coat purity）. The mechanism of a crystallizing drop is shown as direct evidence of the ongoing process. Moreover, solidified tablet batches are analyzed for the purity of their coating by measuring the ibuprofen concentration. This optimization process is carried out through multiple stages of development and condition enhancements in order to produce the most pure tablet coating. As a result, a trial showing an almost purely coated tablet is presented here.

Biomimetics in Production Organization -A Literature Study and Framework

引用

Journal of Bionic Engineering 2016年第2期13卷 200-212页

作者： Kirsten Reisen ulrich Teschemacher Michael Niehues Gunther Reinhart Institute for Machine Tools and Industrial Management Technische Universitat Miinchen ( TUM) Boltzmannstrafle 15 85748 Garch ing Germany

Biomimetics is an established field in research and industry. Current approaches focus on the use of biological principles in product development, while large potentials have also been identified for transferring organisational principles from nature to production organisation. This study gives a comprehensive overview of existing literature and illustrates that only fragmented research is being conducted at present. In order to enable systematic translation into methods that are available to practitioners, a framework is developed which allows the body of literature to be structured and potential fields not being researched at present to be identified. It also points out that some biological principles receive more attention in research approaches and practical implementation in production organisation than others. Furthermore, correlations between biological principles and principles in production are identified that there have already been successful translations of biomimetic approaches to production organisation. On the other hand, it suggests that there are numerous promising approaches only described in an initial paper that need further research before they can be implemented in practice.
