Etablierung des Phage Display-Verfahrens für die Optimierung der Trypsiligase
Creators: name: Gissel, Sabrina
Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt
Year: 2017
Subjects: subject: 572

description: Im Rahmen dieser Dissertation wird das Phage Display-Verfahren als in vitro Selektionsverfahren für die Optimierung der bereits entwickelten Trypsiligase etabliert, die unter anderem für die regiospezifische Modifizierung von Antikörper-Wirkstoff-Konjugaten eingesetzt wird. Gegensätzlich zu der konventionellen Anwendung dieser evolutiven Technologie – typischerweise der Optimierung des Bindungsverhaltens von Enzymen und Proteinen – wurde der Fokus hier auf eine Reduzierung der nativen Sekundärhydrolyseaktivität des Biokatalysators gelegt, die eine Verschlechterung der synthetischen Eigenschaften des Biokatalysators hervorruft. Zu diesem Zweck wurde eine innovative Selektionsmethode entwickelt und etabliert, die auf dem Katalysemechanismus der Trypsiligase basiert und die das kovalente Acyl-Enzym-Intermediat als Selektionsstruktur im Selektionsprozess einsetzt. Die generelle Funktionalität der Selektionsmethode wurde im Rahmen dieser Dissertation bestätigt.
description: This study establishes the Phage Display technology as suitable in vitro selection system for directed optimization of the previously designed trypsiligase used for the site-specific synthesis of Antibody-Drug-Conjugates. In contrast to the conventional application of this evolutionary technology – to improve typically the binding behaviour of enzymes or proteins – here focus was exclusively laid on the systematic reduction of the biocatalyst’s native secondary hydrolysis activity impairing the synthetic properties of the designed enzyme. For this purpose, an original selection approach based on the catalytic mechanism of trypsiligase was established using the covalent acyl-enzyme-intermediate as novel pivot for the selection process. The general function of the approach was successfully validated by this study.

description: This paper continues the study of paragrassmann algebras begun in Part I with the definition and analysis of Toeplitz operators in the associated holomorphic Segal-Bargmann space. These are defined in the usual way as multiplication by a symbol followed by the projection defined by the reproducing kernel. These are non-trivial examples of spaces with Toeplitz operators whose symbols are not functions and which themselves are not spaces of functions.

Verschiedene Teilstücke der Makrolid-Struktur 13-Desmethoxy-FK506 wurden synthetisiert und untersucht. Eine konvergente und stereoselektive Synthese des C(10)-C(18)-Fragmentes wird vorgestellt. Ausgehend von D-(-)-Chinasäure wird die Synthese des C(28)-C(33)-Fragmentes vorgestellt. Schlüsselschritte sind homolytische Desoxygenierung, asymmetrische Dihydroxlierung, Methylierungreaktionen und Claisenumlagerung.
description: FK506 is currently under investigation as immunosuppressant after organ transplantation and in several immune diseases. The structure of the 13-demethyleted-FK506 is characterized as a major metabolite. Various parts of the macrolid-structure 13-desmethoxy-FK506 are synthesized and investigated. An convergent and stereoselective synthesis of C(10)-C(18)-fragment of the 13-desmethoxy-FK506 has been achieved. Starting from D-(-)-quinic acid the synthesis of the cyclohexyl fragment C(28)-C(33) are developed. Key steps for the syntheses include homolytic deoxygenation, asymmetric dihydroxylation, methylation reactions and claisen rearrangement.
NJDEP survey of source water for Giardia cysts and Cryptosporidium oocysts
Creators: name: No Name Supplied
Publisher: name: No Publisher Supplied
Year: 1995

description: The presence of microbiological contaminants in water supplies continues to receive growing attention, primarily due to the increase in the number of immune-deficient individuals and the publicity given to waterborne disease outbreaks. Recent pressure to reduce disinfectant levels to meet current disinfection by-product regulations are offset by the risk of possibly allowing infectious organisms to compromise the health of individuals. Giardia Iamblia and Cryptosporidium parvum are pathogenic protozoans that develop environmentally resistant forms capable of withstanding traditional drinking water treatment and disinfection practices. Methods for detecting these parasites in water are relatively new, and are still evolving to become more sensitive and specific. Health officials and water suppliers have become concerned with the presence of these organisms in source and treated water, because Giardia and Cryptosporidium have increasingly been identified as the organisms responsible for waterborne disease outbreaks. This study represents the first statewide evaluation ever done in New Jersey to determine the occurrence and concentration of these parasites in the states's source waters, and is the most extensive study of its kind for any state to date. The timeliness of this study, just prior to the cryptosporidiosis outbreak in Milwaukee, to determine the levels of Cryptosporidium oocysts and Giardia cysts in the surface supplies of the state ofNew Jersey and to evaluate water treatment based on these levels, could not have been more appropriate.

description: In this letter we study metamaterials made out of resonant electric wires arranged on a spatial scale much smaller than the free space wavelength and we show that they present a hybridization band that is insensible to positional disorder. We experimentally demonstrate defect cavities in disordered and ordered samples and prove that, analogous to those designed in photonic crystals, those cavities can present very high quality factors. In addition we show that they display mode volumes much smaller than a wavelength cube, owing to the deep subwavelength nature of the unit cell. We underline that this type of structure can be shrunk down to a period close of a few skin depth. Our approach paves the way towards the confinement and manipulation of waves at deep subwavelength scales in both ordered and disordered metamaterials.

description: We introduce a new discriminant analysis method (Empirical Discriminant Analysis or EDA) for binary classification in machine learning. Given a dataset of feature vectors, this method defines an empirical feature map transforming the training and test data into new data with components having Gaussian empirical distributions. This map is an empirical version of the Gaussian copula used in probability and mathematical finance. The purpose is to form a feature mapped dataset as close as possible to Gaussian, after which standard quadratic discriminants can be used for classification. We discuss this method in general, and apply it to some datasets in computational biology.

description: W-band low-noise amplifier (LNA)MMICs have been developed using a 70 nm metamorphic HEMT (MHEMT)technology.The short gate length in combination with the high indium content of 80%in the channel lead to a maximum transconductance of 1500 ms/mm for a 2x30 µm device.This results in a transit frequency ft of 290 GHz.Two-and three-stage amplifiers were realized in coplanar waveguide technology (CPW)and achieved a small signal gain of 13 dB and 19 dB,respectively.The noise figure at room temperature of both LNAs was below 3 dB. The on-wafer measured output power at the P-1 dB compression point was 5 dBm.A modification of the three stage LNA showed a noise figure of 2.5 dB,with a small signal gain of 15 dB at 94 GHz.
Why wait till marriage? : sexual decision making among Euro-Canadian and Chinese Canadian young adults
Creators: name: Wong, Queenie Yan Kei
Publisher: name: University of British Columbia
Year: 2013

description: Premarital sexual behaviours are more common among Euro Canadian young adults than Chinese young adults. While researchers acknowledge the significant role of culture in explaining the sexual differences between ethnic groups, few have examined how culture shapes the sexual behaviours of Chinese and Euro Canadian young adults. Based on the symbolic interaction framework, this study examines whether Euro-Canadian and Chinese young adults are socialized to engage in sexual behaviour for different reasons. In particular, the reasons of interest are positive affection, physical pleasure, peer pressure and partner pressure. Religion and the virtue of filial piety are hypothesized to discourage premarital sex. This study also looks at the effects of acculturation on the levels of sexual involvement. This is an exploratory study, and quantitative data were collected from university students residing in Greater Vancouver via an online survey. In contrast with previous findings, ethnicity did not predict the different levels of premarital sexual involvement observed in the university respondents. Rather, this study revealed that the respondents’ levels of sexual involvement were related to the reasons why they engage, or not engage, in sex. A limitation of the study was the small sample size and its potentially non-representative nature. One of the strengths of the present study is the use of a theoretical framework as the basis of the research.

description: Ausgehend von der Beobachtung, dass in einem Tiermodell für die Therapie des Ewing-Tumors in Anwesenheit CD137Ligand-transgener Tumorzellen die von Interleukin 2 (IL2) abhängige Expression des immunsuppressiven Enzyms Indolamin-2,3-dioxygenase (IDO) unterdrückt wurde, wurde die Regulation und Funktion von IDO in diesem Modell analysiert. Dabei konnte eine Abhängigkeit zwischen IDO-Expression in Tumorzellen und Interferon- (IFN-Sekretion durch IL2-stimulierte mononukleäre Blutzellen (PBMC) gezeigt werden. Durch Stimulation von CD137 konnte teilweise eine Hemmung der IDO-Induktion bewirkt werden. Erstmals konnte weiterhin die Expression von IDO in verschiedenen Ewing-Tumor-Zelllinien nach Inkubation mit IFN belegt werden. Diese Tumor-Zellen erlangten hierdurch die Fähigkeit, die Proliferation von PBMC zu hemmen. Mit Hilfe der Mikroarray-Technologie konnte das Zytokin Interleukin 17F (IL17F) durch eine Stimulation über CD137 als stark exprimiert in T-Zellen identifiziert werden. Durch IL17F konnte in gemischten Lymphozyten/Tumorzellkulturen die Proliferation von PBMC und die Antitumorwirkung von IL2 gesteigert werden.

The purpose of this report is to summarize and analyze the results and effects of the 'testing program mandated by the 1983 amendments to the New Jersey Safe Drinking Water Act and make recommendations concerning Safe Drinking Water Act activities. As well, we hope to inform the interested public and regulated community of the quality of New Jersey drinking water. This report provides an analysis of the water quality, violations, and enforcement actions from two general types of public water systems: community water systems and non-community water systems. The non-community water systems are further categorized into transient non-community water systems and non-transient non-community water systems. The monitoring regulations in effect in 1991-1992 were nearly equivalent for both types of non-community systems.

description: Direction of arrival (DOA) estimation is a classical problem in signal processing with many practical applications. Its research has recently been advanced owing to the development of methods based on sparse signal reconstruction. While these methods have shown advantages over conventional ones, there are still difficulties in practical situations where true DOAs are not on the discretized sampling grid. To deal with such an off-grid DOA estimation problem, this paper studies an off-grid model that takes into account effects of the off-grid DOAs and has a smaller modeling error. An iterative algorithm is developed based on the off-grid model from a Bayesian perspective while joint sparsity among different snapshots is exploited by assuming a Laplace prior for signals at all snapshots. The new approach applies to both single snapshot and multi-snapshot cases. Numerical simulations show that the proposed algorithm has improved accuracy in terms of mean squared estimation error. The algorithm can maintain high estimation accuracy even under a very coarse sampling grid.

description: For LMDS and MVDS systems, a compact Image Rejection Star Mixer has been developed for use as both up-and down converter.The circuit has been designed in order to ease the integration,to reduce the size and finally to reach the cost requirements for such systems.The MMIC is fabricated on UMS commercially available PH25 GaAs PHEMT processes.At 40-GHz LO-frequency,the up conversion losses are only 7 dB for an LO power of 18 dBm and 1.5-GHz IF.The image rejection is better than –25 dB and the LO/RF isolation is better than 25 dB.With a chip area of only 2 mm 2,compared to previously reported results for image rejection double balanced mixer MMICs operating in the 35-45-GHz frequency range,this represents a chip size reduction by more than 30 %.

description: The experimental transport scattering rate was determined for a wide range of optimally doped transition metal-substituted FeAs-based compounds with the ThCr2Si2 (122) crystal structure. The maximum transition temperature Tc for several Ba-, Sr-, and Ca-based 122 systems follows a universal rate of suppression with increasing scattering rate indicative of a common pair-breaking mechanism. Extraction of standard pair-breaking parameters puts a limit of \sim26 K on the maximum Tc for all transition metal-substituted 122 systems, in agreement with experimental observations, and sets a critical scattering rate of 1.5x10^14 s^-1 for the suppression of the superconducting phase. The observed critical scattering rate is much weaker than that expected for a sign-changing order parameter, providing important constraints on the nature of the superconducting gap in the 122 family of iron-based superconductors.

description: Advanced circuits based on metamorphic HEMT (MHEMT)technologies on 4 ”GaAs substrates for both millimeter-wave,and mixed- signal applications are presented.Extrinsic cut-off frequencies of ft =293 GHz and fmax =337 GHz were achieved for a 70 nm gate length metamorphic HEMT echnology.The MMIC process obtains high yield on  transistor and circuit level.Single-stage low-noise amplifiers demonstrate a small signal gain of 13 dB and a noise figure of 2.8 dB at 94 GHz.An amplifier MMIC developed for D-Band operation features a gain of 15 dB at 160 GHz.The achieved results are comparable to state- of-the-art InP-based HEMT technologies.In order to realize 80 Gbit/s digital circuits,a process with 100 nm gate length enhancement type HEMTs with a transit frequency of 200 GHz is used.Three metalization layers are available for interconnects.The parasitic capacitance of the interconnects is kept low by using BCB and plated air bridge technology.Based on this process,static and dynamic frequency dividers achieve a maximu  toggle frequency of 70 GHz and 108 GHz,respectively .

description: Compared to SiGe,InP HBTs offer superior electron transport but inferior scaling and parasitic reduction.Figures of merit for mixed-signal ICs are developed and HBT scaling laws for improved circuit speed are introduced.Device and circuit results are summarized, including >370 GHz f W &fmax HBTs,174 GHz amplifiers,75 GHz power amplifiers,87 GHz static frequency dividers, and 8 GHz '6 ADCs.To compete with 100 nm SiGe processes,InP must be similarly scaled.Device structures and initial results are shown for two processes intended for high-yield fabrication of low-parasitic InP HBTs at ~300 nm emitter width.

description: We study the production of photons and dileptons during the pre-equilibrium Glasma stage in heavy ion collisions and discuss the implications in light of the PHENIX data. We find that the measured distributions of such electromagnetic emissions, while having some features not well understood if hypothesized to entirely arise from a thermalized Quark-Gluon Plasma, have some qualitative features that might be described after including effects from a thermalizing Glasma. The shape and centrality dependence of the transverse momentum spectra of the so-called "thermal photons" are well described. The mass and transverse momentum dependence of intermediate mass dileptons also agree with our estimates. The low transverse momenta from which the excessive dileptons (in low to intermediate mass region) arise is suggestive of emissions from a Bose condensate. We also predict the centrality dependence of dilepton production. Uncertainties in the current approach and improvements in the future are discussed.

description: We characterize nanostructures of Bi2Se3 that are grown via metalorganic chemical vapor deposition using the precursors diethyl selenium and trimethyl bismuth. By adjusting growth parameters, we obtain either single-crystalline ribbons up to 10 microns long or thin micron-sized platelets. Four-terminal resistance measurements yield a sample resistivity of 4 mOhm-cm. We observe weak anti-localization and extract a phase coherence length l_phi = 178 nm and spin-orbit length l_so = 93 nm at T = 0.29 K. Our results are consistent with previous measurements on exfoliated samples and samples grown via physical vapor deposition.

description: Trapezoidal words are words having at most $n+1$ distinct factors of length $n$ for every $n\ge 0$. They therefore encompass finite Sturmian words. We give combinatorial characterizations of trapezoidal words and exhibit a formula for their enumeration. We then separate trapezoidal words into two disjoint classes: open and closed. A trapezoidal word is closed if it has a factor that occurs only as a prefix and as a suffix; otherwise it is open. We investigate open and closed trapezoidal words, in relation with their special factors. We prove that Sturmian palindromes are closed trapezoidal words and that a closed trapezoidal word is a Sturmian palindrome if and only if its longest repeated prefix is a palindrome. We also define a new class of words, \emph{semicentral words}, and show that they are characterized by the property that they can be written as $uxyu$, for a central word $u$ and two different letters $x,y$. Finally, we investigate the prefixes of the Fibonacci word with respect to the property of being open or closed trapezoidal words, and show that the sequence of open and closed prefixes of the Fibonacci word follows the Fibonacci sequence.

description: Microsystems technology is increasingly comprised of multi-function devices and materials. Heterogeneous integration technologies are being developed to enable the flexible integration of high-performance devices, materials,and circuits.In our approach,the processing required for integration,such as substrate removal and bonding,is coupled with pre-and post-processing to enable new device and materials configurations not achieved in standard fabrication sequences.Materials and device processes and designs must be considered differently in the context of integration.Herein,we examine these issues specifically for InAs-,InP-and GaN-based heterojunction electronic and optoelectronic device integration processes.

description: We investigate the spinor solutions, the spectrum and the symmetry properties of a matrix-valued wave equation whose plane-wave solutions satisfy the superluminal (tachyonic) dispersion relation E^2 = p^2 - m^2, where E is the energy, p is the spatial momentum, and m is the mass of the particle. The equation reads (i gamma^mu partial_mu - gamma^5 m) psi = 0, where gamma^5 is the fifth current. The tachyonic equation is shown to be CP invariant, and T invariant. The tachyonic Hamiltonian H_5 = alpha.p + beta gamma^5 m breaks parity and is non-Hermitian but fulfills the pseudo-Hermitian property H_5(r) = P H^+_5(-r) P^{-1} = PP H^+_5(-r) PP^{-1} where P is the parity matrix and PP is the full parity transformation. The energy eigenvalues and eigenvectors describe a continuous spectrum of plane-wave solutions (which correspond to real eigenvalues for |p|>=m and evanescent waves, which constitute resonances and antiresonances with complex-conjugate pairs of resonance eigenvalues (for |p|<=m) . In view of additional algebraic properties of the Hamiltonian which supplement the pseudo-Hermiticity, the existence of a resonance energy eigenvalues E implies that E^*, -E, and -E^* also constitute resonance energies of H_5.
