  abstract = {Strategies for synthesizing polyhydroxylated piperidines such as iminosugars have received broad attention. These substances are known to interact with carbohydrate related enzymes{,} glycosidases and glycosyltransferases{,} to which also the large enzyme families of chitin synthases and cellulose synthases belong. Many chemical and biological aspects of chitin synthases remain unexplored due to the fact that modulating substances are hardly available or expensive. Starting from enantiopure d- and l-amino acids{,} a series of iminosugars was prepared by a Lewis acid-catalyzed cyclization of amino acid-derived unsaturated aldehydes as key step. Therefore{,} different Lewis acids were tested. For samarium diiodide we observed a superior stereoselectivity in comparison to iron(iii) chloride and methylaluminium dichloride. To increase water solubility for testing and measurement of enzyme activity{,} the cyclization products were further functionalized. We established a novel biological chitin synthesis test system which allows quantitative investigation of chitin synthesis in the chitin fiber producing diatom algae Thalassiosira in vivo under the light microscope. None of the compounds displayed cytotoxicity{,} but two of the four iminosugars increased the length of the chitin fibers produced. This is a strong indicator that these compounds mimic carbohydrates responsible for restarting chitin polymerization.},

  abstract = {The formation of ikaite (CaCO3x6H2O) was studied in the presence and absence of quartz and mica surfaces using desupersaturation curves from cryo-mixed-batch-reactor experiments. Upon nucleation and growth within the reactor, the solution approached solubility of the precipitating carbonate phase. For ikaite, a solubility constant of log Ksp ikaite = −7.3 ± 0.1 was found (T = 0 °C). At supersaturations Ωikaite < 15, the nucleation of ikaite was significantly promoted by the presence of quartz or mica. This promotion prevented a competing nucleation of anhydrous calcium carbonates. In the presence of quartz or mica, therefore, ikaite forms over a much broader supersaturation range than in the absence. Similarly strong promotors of ikaite nucleation rather than anhydrous carbonate nucleation were previously attributed to calcite-inhibiting substances only. At supersaturations Ωikaite ≥ 8, application of classical nucleation theory on induction periods of ikaite formation yielded an effective interfacial energy of 15 ± 3 mJ/m2. Compared to data of anhydrous CaCO3 phases, this interfacial energy is low and expresses the highly hydrated character of ikaite. At supersaturations Ωikaite ≥ 18, a transient amorphous phase appeared besides ikaite. Our results show that a comprehensive understanding of ikaite formation in natural settings requires consideration not only of supersaturation and presence of calcite-inhibitors but also of the presence or absence of mineral surfaces capable of promoting heterogeneous nucleation of ikaite.},

  abstract = {Directed differentiation methods allow acquisition of high-purity cardiomyocytes (CMs) differentiated from human induced pluripotent stem cells (hiPSCs); however, their immaturity characteristic limits their application for drug screening and regenerative therapy. The rapid electrical pacing of cardiomyocytes have been used for efficiently promoting the maturation of cardiomyocytes, here we describe a simple device in modified culture plate on which hiPSC-derived CMs (hiPSC-CMs) can form three-dimensional self-organized tissue rings (SOTRs). Using calcium imaging, we show that within the ring, traveling waves (TWs) of action potential spontaneously originated and ran robustly at a frequency up to 4 Hz. After 2 weeks, SOTRs with TW training showed matured features including structural organization, increased cardiac-specific gene expression, enhanced Ca2+-handling properties, an increased oxygen-consumption rate, and enhanced contractile force. We subsequently used a mathematical model to interpret the origination, propagation, and long-term behavior of the TWs within the SOTRs. This new idea for spontaneous hiPSC-CM maturation also has potential for pacing the electrical excitable cells such as neuron and retina cells for various applications.},

  abstract = {Hydrogels are versatile materials{,} finding applications as adsorbers{,} supports for biosensors and biocatalysts or as scaffolds for tissue engineering. A frequently used building block for chemically cross-linked hydrogels is poly(ethylene glycol) diacrylate (PEG-DA). However{,} after curing{,} PEG-DA hydrogels cannot be functionalized easily. In this contribution{,} the stiff{,} rod-like tobacco mosaic virus (TMV) is investigated as a functional additive to PEG-DA hydrogels. TMV consists of more than 2000 identical coat proteins and can therefore present more than 2000 functional sites per TMV available for coupling{,} and thus has been used as a template or building block for nano-scaled hybrid materials for many years. Here{,} PEG-DA (Mn = 700 g mol−1) hydrogels are combined with a thiol-group presenting TMV mutant (TMVCys). By covalent coupling of TMVCys into the hydrogel matrix via the thiol-Michael reaction{,} the storage modulus of the hydrogels is increased compared to pure PEG-DA hydrogels and to hydrogels containing wildtype TMV (wt-TMV) which is not coupled covalently into the hydrogel matrix. In contrast{,} the swelling behaviour of the hydrogels is not altered by TMVCys or wt-TMV. Transmission electron microscopy reveals that the TMV particles are well dispersed in the hydrogels without any large aggregates. These findings give rise to the conclusion that well-defined hydrogels were obtained which offer the possibility to use the incorporated TMV as multivalent carrier templates e.g. for enzymes in future studies.},

  abstract = {Holospora and related bacteria are a group of obligate Paramecium symbionts. Characteristic features are their infectivity, the presence of two distinct morphotypes, and usually a strict specialization for a single Paramecium species as host and for a nuclear compartment (either somatic or generative nucleus) for reproduction. Holospora caryophila steps out of line, naturally occurring in Paramecium biaurelia and Paramecium caudatum. This study addresses the phylogenetic relationship among H. caryophila and other Holospora species based on 16S rRNA gene sequence comparison analyzing the type strain and seven new macronuclear symbionts. Key aspects of Holospora physiology such as infectivity, symbiosis establishment and host range were determined by comprehensive infection assays. Detailed morphological investigations and sequence-based phylogeny confirmed a high similarity between the type strain of H. caryophila and the novel strains. Surprisingly, they are only distantly related to other Holospora species suggesting that they belong to a new genus within the family Holosporaceae, here described as Preeria caryophila comb. nov. Adding to this phylogenetic distance, we also observed a much broader host range, comprising at least eleven Paramecium species. As these potential host species exhibit substantial differences in frequency of sexual processes, P. caryophila demonstrates which adaptations are crucial for macronuclear symbionts facing regular destruction of their habitat.},

  abstract = {Biominerals are composite materials formed by organisms. Enzymes are among the characteristic features of these organisms, and various enzymes are also involved in biomineral formation. Nevertheless, light on the role of enzymes in biomineralization processes may be shed from different directions. This chapter presents a list of enzymes from selected organisms, from bacteria up to complex metazoans, that are currently known to be involved in biomineralization. Based upon early views on catalysis and the fact that biomineralization has been defined as “A new chemistry” (S. Mann, Biomineralization, Oxford 2002), several biopolymers that are typically associated along with biominerals, are suggested to act as a special category of enzymes. Within this framework, the way from ions to minerals is discussed with respect to catalytic requirements that can be fulfilled by the different categories of enzymes. The role of enzymes is clarified by discussing physico-chemical principles of biomineralization, including solution chemistry, and phase transformations from amorphous to crystalline solids. Special attention is paid to enzymes involved in mineral–matrix interactions, as well as in the formation of the matrix. The consequences of the presented facts are discussed with respect to the evolution of biominerals, and with respect to targeting these enzymes for biomimetic engineering.},

  abstract = {Summary
After being chemotactically attracted by its host, marine diatoms of the genus Coscinodiscus, the Pirsonia flagellates are guided by the topography of the host cell surface to the rimoportulae through which the trophosome, a basally formed pseudopodium, penetrates into the diatom. Cytochalasin D does not disturb the chemotaxis of the flagellates but inhibits their attachment. Pirsonia diadema and P. guinardiae, feeding on Coscinodiscus and on Guinardia flaccida, respectively, are very similar in their fine structure. The anterior flagellum has tubular hairs which seem to belong to the tripartite, stramenopile type. They are synthesized within the ER and exocytosed by the Golgi apparatus. In certain developmental stages the posterior flagellum and the cell body bear ,,knotted hairs`` which differ in length. The mode of their formation is unknown. The mitochondria have unique non-contorted tubular cristae which are parallel to each other. The few dictyosomes have a parabasal position. The flagellar root apparatus consists of fibrillar bands which connect the basal body of the anterior flagellum with the nucleus and with the basal body of the posterior flagellum. Other fibrillar bands and a few microtubules run from the basal bodies to the cell surface. The organization of the flagellar root apparatus thus differs from that of typical stramenopiles. The taxonomic position of Pirsonia is discussed.},
