This book unearths how this remarkable transformation derived from a network of liberal American occupation officials, and returned émigrés, or remigrés, of the Marxist Social Democratic Party (SPD). This network derived from lengthy physical and political journeys. After fleeing Hitler, German-speaking self-professed 'revolutionary socialists' emphasized 'anti-totalitarianism' in New Deal America and contributed to its intelligence apparatus. These experiences made these remigrés especially adept at cultural translation in postwar Berlin against Stalinism. This book provides a new explanation for the alignment of Germany's principal left-wing party with the Western camp. While the Cold War has traditionally been analyzed from the perspective of decision makers in Moscow or Washington, this study demonstrates the agency of hitherto marginalized on the conflict's first battlefield. Examining local political culture and social networks underscores how both Berliners and émigrés understood the East-West competition over the rubble that the Nazis left behind as a chance to reinvent themselves as democrats and cultural mediators, respectively.

Beantwortet werden elementare Fragen wie „Was ist Korruption?“, „Worin genau besteht ihre Schädlichkeit?“ und „Wer ist ihr Opfer?“. Auf der Basis dieser theoretischen Grundlage sowie unter Berücksichtigung auch der österreichischen, schweizerischen und internationalen Anti-Korruptionsvorschriften formuliert die Abhandlung als unmittelbaren praktischen Nutzen für die Gesetzgebung ein das Korruptionsunrecht in optimaler Weise einfangendes Set an flexibel anpassbaren Modelltatbeständen. Zudem enthält das Werk eine kritische Würdigung des gesamten Korruptionsstrafrechts des StGB (einschließlich der neuen Vorschriften zur Bekämpfung der Korruption im Sport und im Gesundheitsweisen) und bietet für dieses konkrete Auslegungsvorschläge zu sämtlichen zentralen Streitfragen.']]

We characterize the value function in terms of the dynamic programming equation, which turns out to be an elliptic, fully non-linear partial differential equation of second order. In addition, we prove a classical verification theorem and apply it to several examples. Furthermore, we consider the problem of optimally stopping a one-dimensional regular continuous strong Markov process with a stopping time satisfying an expectation constraint. We show that it is sufficient to consider only stopping times such that the law of the process at the stopping time is a weighted sum of 3 Dirac measures. The proof uses results on Skorokhod embeddings in order to reduce the stopping problem to a linear optimization problem over a convex set of probability measures. We apply the results to analyze a sequential testing problem and show that in this problem the optimal stopping times are given by at most two consecutive exit times of intervals. Finally, using the theory of Tchebycheff systems we examine when we can reduce the set of stopping times in the constrained problem to first exit times of intervals. In this case, the law of the process at the stopping time is a weighted sum of at most 2 Dirac measures.']

To give a brief explanation, a focused light irradiation induces a local photoisomerization that creates a concentration gradient at the…']

Contrarily, the cultural landscape approach puts current ecosystem structure into the context of evolution and human history, thus suggests that human-created habitats are crucial in maintaining the locally adapted species assemblage. <br>The goal of this dissertation was to understand the human–habitat–biodiversity interconnections through conducting an interdisciplinary study in the alpine grassland landscape of the eastern Qinghai-Tibetan Plateau, which is one center of bird endemism of Asia. The research also aimed to make science-based conservation recommendations for the protection of the Tibetan avifauna.<br>To disentangle human impacts on the vegetation changes of alpine pastures in eastern Tibet, I integrated oral history study, participatory GIS and remote sensing analysis of Landsat and MODIS time-series in order to detect the turning points of land-use and land-cover changes. Results showed that privatizations of livestock and pastures since 1984 triggered the recent grassland degradation. South-facing, mild-slope winter pastures located in higher altitudes were most susceptible to the degradation. With a time-lag of thirty years, the degradation turning point was detected in the year 2006. However, the non-synchronized land-use and land-cover changes confused local people’s perceptions of the causality. This finding bears implications for conservation management, which puts increasing weight on the traditional ecological knowledge (chapter 5).<br>To examine the species–environment relationship of the eastern Tibetan bird assemblage, I first developed a comprehensive set of habitat predictors empl ...']

The pathogens replicate inside host cells. Therefore, the bacteria produce a large array of effectors, which are secreted by the Dot/Icm (Defective in organelle trafficking/Intracellular multiplication) type 4 secretion system (T4SS) into the cytosol of the target cell. Many of the injected effectors possess enzyme activities and, thereby, interfere with host cell functions to promote intracellular bacterial multiplication. Some L. pneumophila effectors (e.g. Lgt1-3 and SetA) harbor glycosyltransferase (GT) activities and share structural similarity with clostridial glucosylating toxins, which are the prototypes of glucosylating virulence factors. Aim of the study was the identification of novel putative Legionella glycosyltransferases by genome sequence analysis and their characterization by biochemical, molecular- and cell biological methods. In the first part of the thesis, the L. longbeachae protein Llo1578 was analyzed, which shares amino acids sequence similarity with the Lgt glucosyltransferases from L. pneumophila. Llo1578 displayed in vitro glucohydrolase and autoglucosylating activities using UDP-glucose as a sugar donor. Expression of Llo1578 in yeast exhibited cytotoxic effects, which were dependent on the glucosylating activity of the protein. Thus, the variants of Llo1578 with the mutations in the identified catalytic residues W23, D126, D142, N177 and W326 did not affect yeast growth. However, in contrast to the Lgt glucosyltransferases, Llo1578 did not affect in vitro translation and did not modify EF1A, the substrate of the Lgt effectors. Therefore, this study suggests that Llo1578 likely belongs to a new group of Legionella glucosyltransferases with an unknown acceptor specificity. The second part of the thesis was focused on the novel L. pneumophila effector LtpM (Legionella translocating protein M). The study revealed that LtpM is a two-domain protein, which consists of an N-terminal glycosyltransferase domain and a C-terminal phosphatidyl inositol 3-phosphate (PI3P)-binding domain. My studies showed that the N-terminal domain of LtpM is responsible for its glucohydrolase activity with UDP-glucose as the preferred activated sugar.

The book is particularly suitable for readers who are interested in constitutional law and comparative law, but will also be useful to political scientists.', 'Seit der Anerkennung der Elemente der sachunmittelbaren Demokratie in der Verfassungswirklichkeit besteht zwischen dieser und der parlamentarischen Demokratie nach wie vor ein Spannungsverhältnis. Die Arbeit beschäftigt sich mit dem diesbezüglichen Thema der sachunmittelbaren Demokratie, vor allem mit dem Problem des oft als die „deutsche Tradition“ bezeichneten Finanzvorbehalts in der Volksgesetzgebung, dessen Reichweite aber seit der Weimarer Zeit durch verschiedenen Auslegungskriterien bis heute stets umstritten ist. Es wird versucht, aus rechtsdogmatischen, rechtsvergleichenden, rechtshistorischen und rechtspolitischen Untersuchungsperspektiven eine praktische Konkordanz herzustellen, um zu der Entwicklung der sachunmittelbaren Demokratie sowohl in Deutschland als auch in Taiwan beizutragen.Die Arbeit eignet sich vor allem für an Verfassungsrecht und Rechtsvergleichung Interessierte, richtet sich aber auch an Politikwissenschaftler.']]

3A1048804054.jsonld | ['Untersuchungen über die Wirkungen von Zeolithzulagen auf die Pansenfermentation des Rindes in vitro'] | [['Feeding today’s dairy cows has to provide for a stable fermentation in the rumen to allow for the desired productivity. Different feed supplements are used to compensate for imbalances or deficiencies of the ration. Studies demonstrate an impact of zeolite supplementation on rumen metabolism. Zeolites – clinoptilolites, for example – are negatively charged tectosilicates with pores and channels specific of each framework type. As a consequence, they can selectively bind cations from the surrounding medium and ion-exchange existing channel cations for them. Therefore, the objective of this study was to examine the effect of Klinofeed®, a clinoptilolite of sedimentary origin, on the fermentation in the fluid phase of the rumen which appears to be the first possible point of action. An artificial rumen (all-glass, bulk incubation type, closed system) corresponding to the one used by CZERKAWSKI and BRECKENRIDGE (1969) was used. Fermentation processes in the rumen liquid were analyzed during six hours of incubation. The following parameters were measured at three different sampling times (0 h, 3 h, 6 h of incubation): redox potential, pH value, concentrations of glucose and volatile fatty acids (acetic, propionic, n-butyric, n-valeric, hexanoic, i-butyric, i-valeric acid and their sum), production of fermentation gases, concentrations of methane, ammonia, microbial protein and nucleobases (cytosine, uracil, thymine, guanine, adenine and their sum), protozoal motility, numbers of protozoa (in total and differentiated according to their size). For the incubation intervals 0–3 h, 3–6 h and 0–6 h the magnitude of the changes, the production or the consumption of the parameters were calculated. Two distinct trials with different zeolite dosages were conducted. The first trial consisted of 45 days when 0,34 g Klinofeed® were applied in accordance with the producer’s recommended daily amount per animal. In the course of the second trial (eleven days) the double dose of the clinoptilolite (0,68 g) was added. The supplementation of Klinofeed® moderately changed the fermentation pattern and stabilized the environment (pH value lower in the control fermenters) in both trials. The glucose added as substrate for the microorganisms was almost completely metabolized during the first three hours of incubation under control conditions as well as in the zeolite fermenters without any evidence of an increase in the bacterial matter in the zeolite fermenters (as indicated by the lacking increased production of microbial protein or nucleobases). Hence, it is justified to assume that the increased production of volatile fatty acids (trial 1: +7,8 % n-butyric acid; trial 2: +19,3 % acetic, +8,6 % propionic and +9,9 % n-butyric acid, sum of all measured volatile fatty acids +8,8 %; in each case for the complete incubation and relative to control) and methane [trial 1 (0–6 h): +14,4 %; trial 2 (0–3 h): +12,5 %] was the result of relative shifts in the rumen microbiome and/or of the metabolic pathways that took place. No further methods were available to substantiate the assumption of a microbiome shift. Neither was the mechanism by which Klinofeed® could influence the microbiome revealed. This gap in knowledge should be closed in future studies.', 'Die bedarfsgerechte Fütterung heutiger Milchkühe muss eine stabile Pansenfermentation erzeugen, denn nur so können die Kühe die gewünschten Leistungen erbringen. Um dies sicherzustellen, werden verschiedene Futtermittel-zusatzstoffe eingesetzt, die Unausgewogenheiten oder Mängel der Ration aus-gleichen. Studien zeigen, dass Zeolithe, zum Beispiel Klinoptilolithe, die infolge ihres Aufbaus (negativ geladene Kristallgitter mit für jeden Gittertyp spezifischen Kanälen und Hohlräumen) selektiv Kationen aus dem umgebenden Milieu aufnehmen und vorhandene Kanalkationen durch diese ersetzen können, den Pansenstoffwechsel von Rindern beeinflussen. Aus diesem Grund wurde in der vorliegenden Arbeit die Wirkung von Klinofeed®, einem Klinoptilolith sedimentären Ursprungs, auf die Fermentation im flüssigen Panseninhalt des Rindes, als erstem möglichem Wirkungsort, unter In-vitro-Bedingungen untersucht. Mit dem verwendeten Kurzzeitsystem nach CZERKAWSKI und BRECKENRIDGE (1969), einem künstlichen Pansen vom geschlossenen Blocktyp, konnten die Fermentationsvorgänge in der flüssigen Phase des Panseninhalts während sechsstündiger Inkubation beurteilt werden. Dazu wurden folgende Parameter an drei Probennahmezeitpunkten (0 h, 3 h, 6 h Inkubationsdauer) erfasst: Redoxpotential, pH-Wert, Glucosekonzentration, Konzentrationen der flüchtigen Fettsäuren (Essig-, Propion-, n-Butter-, n-Valerian-, Hexan-, i-Butter- und i-Valeriansäure sowie deren Summe), Gasproduktion, Methankonzentration, Ammoniakkonzentration, bakterieller Proteingehalt, Konzentrationen der Nukleobasen (Cytosin, Uracil, Thymin, Guanin, Adenin sowie deren Summe), Protozoenmotilität und Anzahl der Protozoen in Summe sowie differenziert nach Größe. Aus den Messwerten wurde die Größe der Veränderung bzw. die Produktion oder der Verbrauch der Parameter während der Inkubationsintervalle 0–3 h, 3–6 h und 0–6 h errechnet. Zwei Versuche mit unterschiedlicher Klinofeed®-Dosis wurden durchgeführt. Im ersten Versuch wurde an 45 Versuchstagen die der Fütterungsempfehlung entsprechende Menge von 0,34 g Klinofeed® pro Fermenter zugelegt. Im zweiten Versuch (elf Versuchstage) wurde die Dosis auf 0,68 g verdoppelt. Durch die Zulage von Klinofeed® wurde das Fermentationsmuster in beiden Versuchen moderat verändert und das Milieu stabilisiert (pH-Wert in den Kontrollfermentern niedriger als in den mit Klinofeed® versetzten Zulagefermentern). Die als Substrat eingesetzte Glucose wurde sowohl in den Kontroll- als auch in den Zulagefermentern bereits innerhalb der ersten drei Inkubationsstunden beinahe vollständig verstoffwechselt, ohne dass in den Zulagefermentern eine Vermehrung der Bakterienmasse (bakterielle Protein- bzw. Nukleobasenproduktionen) gegenüber den Kontrollen belegt werden konnte. Deshalb ist anzunehmen, dass die Steigerungen der Produktion flüchtiger Fettsäuren (Versuch 1: +7,8 % n-Buttersäure; Versuch 2: +19,3 % Essig-, +8,6 % Propion- und +9,9 % n-Buttersäure, in Summe aller flüchtigen Fettsäuren +8,8 %; jeweils über die Gesamtinkubation und in Relation zur Kontrolle) und der Methanproduktion [Versuch 1 (0–6 h): +14,4 %; Versuch 2 (0–3 h): +12,5 %] durch relative Verschiebungen innerhalb des Pansenmikrobioms und/oder der benutzten Stoffwechselwege hervorgerufen wurden. Mit den Methoden, die für die eigenen Versuche zur Verfügung standen, war es nicht möglich, den Erklärungsansatz einer Mikrobiomveränderung weiter zu erhärten. Auch die Klärung des eigentlichen Wirkmechanismus von Klinofeed® im Pansen sollte Gegenstand zukünftiger Untersuchungen sein.']] | ['gnd:4067660-2', 'gnd:4123904-0', 'gnd:4169916-6', 'gnd:4252358-8', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A1048804054'] | ['Zeolith', 'Pansen', 'Milchkuh', 'Beifutter'] | Document

Studien zeigen, dass Zeolithe, zum Beispiel Klinoptilolithe, die infolge ihres Aufbaus (negativ geladene Kristallgitter mit für jeden Gittertyp spezifischen Kanälen und Hohlräumen) selektiv Kationen aus dem umgebenden Milieu aufnehmen und vorhandene Kanalkationen durch diese ersetzen können, den Pansenstoffwechsel von Rindern beeinflussen. Aus diesem Grund wurde in der vorliegenden Arbeit die Wirkung von Klinofeed®, einem Klinoptilolith sedimentären Ursprungs, auf die Fermentation im flüssigen Panseninhalt des Rindes, als erstem möglichem Wirkungsort, unter In-vitro-Bedingungen untersucht. Mit dem verwendeten Kurzzeitsystem nach CZERKAWSKI und BRECKENRIDGE (1969), einem künstlichen Pansen vom geschlossenen Blocktyp, konnten die Fermentationsvorgänge in der flüssigen Phase des Panseninhalts während sechsstündiger Inkubation beurteilt werden. Dazu wurden folgende Parameter an drei Probennahmezeitpunkten (0 h, 3 h, 6 h Inkubationsdauer) erfasst: Redoxpotential, pH-Wert, Glucosekonzentration, Konzentrationen der flüchtigen Fettsäuren (Essig-, Propion-, n-Butter-, n-Valerian-, Hexan-, i-Butter- und i-Valeriansäure sowie deren Summe), Gasproduktion, Methankonzentration, Ammoniakkonzentration, bakterieller Proteingehalt, Konzentrationen der Nukleobasen (Cytosin, Uracil, Thymin, Guanin, Adenin sowie deren Summe), Protozoenmotilität und Anzahl der Protozoen in Summe sowie differenziert nach Größe. Aus den Messwerten wurde die Größe der Veränderung bzw. die Produktion oder der Verbrauch der Parameter während der Inkubationsintervalle 0–3 h, 3–6 h und 0–6 h errechnet. Zwei Versuche mit unterschiedlicher Klinofeed®-Dosis wurden durchgeführt. Im ersten Versuch wurde an 45 Versuchstagen die der Fütterungsempfehlung entsprechende Menge von 0,34 g Klinofeed® pro Fermenter zugelegt. Im zweiten Versuch (elf Versuchstage) wurde die Dosis auf 0,68 g verdoppelt. Durch die Zulage von Klinofeed® wurde das Fermentationsmuster in beiden Versuchen moderat verändert und das Milieu stabilisiert (pH-Wert in den Kontrollfermentern niedriger als in den mit Klinofeed® versetzten Zulagefermentern). Die als Substrat eingesetzte Glucose wurde sowohl in den Kontroll- als auch in den Zulagefermentern bereits innerhalb der ersten drei Inkubationsstunden beinahe vollständig verstoffwechselt, ohne dass in den Zulagefermentern eine Vermehrung der Bakterienmasse (bakterielle Protein- bzw. Nukleobasenproduktionen) gegenüber den Kontrollen belegt werden konnte. Deshalb ist anzunehmen, dass die Steigerungen der Produktion flüchtiger Fettsäuren (Versuch 1: +7,8 % n-Buttersäure; Versuch 2: +19,3 % Essig-, +8,6 % Propion- und +9,9 % n-Buttersäure, in Summe aller flüchtigen Fettsäuren +8,8 %; jeweils über die Gesamtinkubation und in Relation zur Kontrolle) und der Methanproduktion [Versuch 1 (0–6 h): +14,4 %; Versuch 2 (0–3 h): +12,5 %] durch relative Verschiebungen innerhalb des Pansenmikrobioms und/oder der benutzten Stoffwechselwege hervorgerufen wurden. Mit den Methoden, die für die eigenen Versuche zur Verfügung standen, war es nicht möglich, den Erklärungsansatz einer Mikrobiomveränderung weiter zu erhärten. Auch die Klärung des eigentlichen Wirkmechanismus von Klinofeed® im Pansen sollte Gegenstand zukünftiger Untersuchungen sein.']]

3A1049235541.jsonld | ['Evaluation of fertilization capacity of cryopreserved stallion sperm, directly after thawing and after cooled storage'] | [['In the modern equine breeding industry, use of cryopreserved semen is increasing. In comparison to using fresh or cooled semen, however, costs are higher and pregnancy rates lower. This is associated with the fact that using cryopreserved sperm requires special equipment for transport, storage and handling. Furthermore, sperm viability is reduced after cryopreservation, and cryopreserved semen therefore needs to be used for insemination close to ovulation. The aim of the studies described in this thesis was to investigate if cryopreserved semen maintains its fertilizing ability after thawing and cooled overnight transport (i.e. 24 h storage at 4°C). Furthermore, it was tested if performing insemination at a defined time point after hCG application was as effective as performing insemination close to ovulation (with inspection every 6 h). These simplifications would reduce costs and make cryopreserved insemination doses available to more practitioners and breeders. This study was divided in three parts. (1) First, viability of cryopreserved stallion sperm was determined in vitro; directly after thawing, after dilution with different extenders as well as an additional 24 h cooled storage. For cooled storage, to mimic transport conditions, thawed cryopreserved semen was diluted, transferred to a syringe and placed in a polystyrene transport box with a cool pack for maintenance at 4°C. Sperm plasma- and acrosomal membrane integrity was determined using flow cytometric analysis. Motility characteristics were evaluated using computer assisted sperm analysis (CASA). Only small differences were found between percentages of membrane intact sperm directly after thawing and after an additional 24 h cooled storage, irrespective of the extender used for dilution. Furthermore, percentages of progressively motile sperm were only 3−8% decreased after 1 d cooled storage. (2) Then, for testing fertilizing potential of cryopreserved sperm in vitro, a heterologous oocyte-binding assay was used. Therefore, cryopreserved stallion sperm was co-incubated with porcine oocytes in capacitation as well as control-medium, after which nuclei were stained and the number of sperm per oocyte/zona was counted. Sperm-oocyte binding was determined to be higher in capacitation than in control medium, and if using diluted versus cryopreserved sperm. Furthermore, the number of sperm bound per oocyte was not negatively affected if cryopreserved sperm was subjected to dilution and 1 d cooled storage after thawing, suggesting that fertilizing capacity was maintained. (3) Finally, an insemination trial was performed to determine mare pregnancy rates using cryopreserved stallion sperm directly after thawing as well as after 24−36 h cooled storage after thawing. In addition, different insemination regimes were tested, including insemination after a defined duration after hCG-administration as well as maximally 6 h after ovulation (i.e. determined according to ultrasound ovulation controls). The insemination trial revealed that pregnancy rates achieved with using cryopreserved sperm after thawing and 1 d cooled storage (13/25, 52%) were not significantly different from when using freshly thawed sperm (7/10, 70%), nor were pregnancy rates negatively affected if insemination was planned according to the moment of hCG application instead of ovulation controls. Taken together, viability and fertilizing capacity of cryopreserved stallion semen is not negatively affected if stored at 4°C for up to 24−36 h after thawing. Moreover, if used for artificial insemination, mare pregnancy rates are similar as those obtained with using freshly thawed sperm.', 'Der Einsatz von Tiefgefriersamen in der modernen Pferdezucht nimmt zu, ist jedoch im Vergleich zu Frisch- und Kühlsamen mit höheren Kosten und geringeren Trächtigkeitsraten verbunden.

Das Ziel der in dieser Arbeit beschriebenen Studien war herauszufinden, ob Tiefgefriersamen seine Fertilisationsfähigkeit nach Auftauen und gekühltem Transport über Nacht (also 24 Stunden Lagerung bei 4°C) erhält. Außerdem wurde getestet, ob eine Besamung zu definierten Zeitpunkten nach hCG-Applikation genauso effektiv ist wie eine Besamung nah am Zeitpunkt der Ovulation (nach Ultraschallkontrolle alle 6 Stunden).

3A1049242084.jsonld | ['Die Rolle des zentralen cholinergen Systems und weiterer Neurotransmitter in Nagermodellen der Temporallappenepilepsie'] | [['Epilepsy is one of the most common chronic neurological diseases of the central nervous system in humans and animals. Despite the development of various new antiepileptic drugs in the last few decades, obstacles to effective epilepsy treatment remain, including pharmacoresistance in more than 30 % of human patients and 50 % of dog patients as well as pronounced side effects. An antiepileptogenic therapy that suppress epilepsy development itself before the onset of spontaneous recurrent seizures would be preferable to the uncertain outcomes of symptomatic and lifelong therapy with antiepileptic drugs. Since epileptogenic processes remain barely understood, antiepileptogenic therapies are not feasible and, therefore, constitute one of the most important fields of current epilepsy research. In this context, there has so far been little research on the central cholinergic system compared to the excitatory glutamatergic and inhibitory GABAergic system. Nevertheless, recent studies have shown that an enhanced cholinergic signal is not only important for the induction and possibly maintenance of seizures, but also could bear epileptogenic properties. The goal of my work consisted of monitoring and characterizing extracellular levels of acetylcholine (ACh) in the hippocampus of rats between the initial brain insult leading to epilepsy and the chronic phase of epilepsy. Two different post-status epilepticus (SE) models of acquired temporal lobe epilepsy were used to assess model-specific differences: the chemical lithium-pilocarpine model and the prolonged electrical stimulation of the basolateral amygdala (BLA) model. The neurotransmitter ACh was sampled via microdialysis in the hippocampus of rats and analyzed via high performance liquid chromatography. We also sought to create a basic concept for strategies of antiepileptogenic therapies, e.g. by the antimuscarinic drug scopolamine. Furthermore, amino acid neurotransmitters like g-Aminobutyric acid (GABA), glutamate, aspartate, serine, glycine, and glutamine were analyzed to assess other neurochemical changes during epilepsy development. Extracellular levels of ACh in the dialysates rose significantly in comparison to control animals during SE in the lithium-pilocarpine model. For the first time, we were able to determine a similar (albeit lower) rise in ACh levels in the BLA model. During epileptogenesis and chronic epilepsy, no changes were observed in both models. However, ACh values in chronic epileptic animals were significantly lower than in animals in which spontaneous recurrent seizures were not detected. Though GABA and glutamate remained unchanged during SE in the chemical model, a significant rise of the concentrations of both neurotransmitters was detected in comparison to control values in the electrical model, persisting even after termination of SE. In the electrical model, glutamate levels also rose during the chronic epileptic phase. In the chemical model, there was a significant transient rise of GABA levels in nonepileptic animals in comparison to epileptic animals during the phase of epileptogenesis whereas glutamate levels of epileptic animals were significantly lower compared to control values in the chronic epileptic phase. This work allowed the first overview of extracellular ACh levels in two models of temporal lobe epilepsy in the rat hippocampus from induction of SE to the chronic epileptic phase. The extracellular rise in ACh concentrations during SE could imply its role in mechanisms of generating, maintaining, and possibly even inhibiting SE regardless of stimulus type. In contrast, GABA and glutamate seem to be more model-specific. Interestingly, values of GABA were partly increased in nonepileptic animals during the latent period. This increase could represent an attempt of the brain to prevent epileptogenic processes. Furthermore, the grade of ACh liberation seems to be positively correlated to the intensity of the SE. However, because changes of ACh levels were not seen in epileptogenesis or the chronic epileptic phase, it is questionable if ACh has epileptogenic properties. Nevertheless, hypersensitivity of the hippocampal tissue to ACh in early epileptogenesis could increase its putative epileptogenic potential. Besides, ACh release seems to be reduced in epileptic animals in the chronic epileptic phase. This reduction of ACh levels could represent a compensation mechanism. Hence, the use of cholinergic antagonists as an interesting approach for antiepileptogenic therapies could not be ruled out.', 'Epilepsien gehören zu den häufigsten chronischen neurologischen Erkrankungen des zentralen Nervensystems bei Mensch und Tier. Trotz der Entwicklung zahlreicher neuer Antiepileptika in den letzten Jahrzehnten stellen eine persistierende Pharmakoresistenz von mehr als 30 % beim Menschen und sogar mehr als 50 % beim Hund sowie Nebenwirkungen weiterhin ein großes Problem dar. Einer solchen lediglich symptomatischen und lebenslangen Behandlung mit ungewissem Erfolg wäre eine transiente antiepileptogene Therapie zur Unterdrückung der Epilepsieentstehung in der Latenzzeit zwischen Hirninsult und dem Auftreten erster spontaner Anfälle vorzuziehen. Da epileptogene Prozesse bis dato jedoch kaum verstanden sind, ist eine antiepileptogene Therapie nicht möglich und stellt einen der aktuell wichtigsten Forschungsaspekte in der Epileptologie dar.

### Title: ['Die Rolle des zentralen cholinergen Systems und weiterer Neurotransmitter in Nagermodellen der Temporallappenepilepsie']
### Abstract:
[['Epilepsy is one of the most common chronic neurological diseases of the central nervous system in humans and animals. Despite the development of various new antiepileptic drugs in the last few decades, obstacles to effective epilepsy treatment remain, including pharmacoresistance in more than 30 % of human patients and 50 % of dog patients as well as pronounced side effects. An antiepileptogenic therapy that suppress epilepsy development itself before the onset of spontaneous recurrent seizures would be preferable to the uncertain outcomes of symptomatic and lifelong therapy with antiepileptic drugs. Since epileptogenic processes remain barely understood, antiepileptogenic therapies are not feasible and, therefore, constitute one of the most important fields of current epilepsy research. In this context, there has so far been little research on the central cholinergic system compared to the excitatory glutamatergic and inhibitory GABAergic system. Nevertheless, recent studies have shown that an enhanced cholinergic signal is not only important for the induction and possibly maintenance of seizures, but also could bear epileptogenic properties. The goal of my work consisted of monitoring and characterizing extracellular levels of acetylcholine (ACh) in the hippocampus of rats between the initial brain insult leading to epilepsy and the chronic phase of epilepsy. Two different post-status epilepticus (SE) models of acquired temporal lobe epilepsy were used to assess model-specific differences: the chemical lithium-pilocarpine model and the prolonged electrical stimulation of the basolateral amygdala (BLA) model. The neurotransmitter ACh was sampled via microdialysis in the hippocampus of rats and analyzed via high performance liquid chromatography. We also sought to create a basic concept for strategies of antiepileptogenic therapies, e.g. by the antimuscarinic drug scopolamine. Furthermore, amino acid neurotransmitters like g-Aminobutyric acid (GABA), glutamate, aspartate, serine, glycine, and glutamine were analyzed to assess other neurochemical changes during epilepsy development. Extracellular levels of ACh in the dialysates rose significantly in comparison to control animals during SE in the lithium-pilocarpine model. For the first time, we were able to determine a similar (albeit lower) rise in ACh levels in the BLA model. During epileptogenesis and chronic epilepsy, no changes were observed in both models. However, ACh values in chronic epileptic animals were significantly lower than in animals in which spontaneous recurrent seizures were not detected. Though GABA and glutamate remained unchanged during SE in the chemical model, a significant rise of the concentrations of both neurotransmitters was detected in comparison to control values in the electrical model, persisting even after termination of SE. In the electrical model, glutamate levels also rose during the chronic epileptic phase. In the chemical model, there was a significant transient rise of GABA levels in nonepileptic animals in comparison to epileptic animals during the phase of epileptogenesis whereas glutamate levels of epileptic animals were significantly lower compared to control values in the chronic epileptic phase. This work allowed the first overview of extracellular ACh levels in two models of temporal lobe epilepsy in the rat hippocampus from induction of SE to the chronic epileptic phase. The extracellular rise in ACh concentrations during SE could imply its role in mechanisms of generating, maintaining, and possibly even inhibiting SE regardless of stimulus type. In contrast, GABA and glutamate seem to be more model-specific. Interestingly, values of GABA were partly increased in nonepileptic animals during the latent period. This increase could represent an attempt of the brain to prevent epileptogenic processes. Furthermore, the grade of ACh liberation seems to be positively correlated to the intensity of the SE. However, because changes of ACh levels were not seen in epileptogenesis or the chronic epileptic phase, it is questionable if ACh has epileptogenic properties. Nevertheless, hypersensitivity of the hippocampal tissue to ACh in early epileptogenesis could increase its putative epileptogenic potential. Besides, ACh release seems to be reduced in epileptic animals in the chronic epileptic phase. This reduction of ACh levels could represent a compensation mechanism. Hence, the use of cholinergic antagonists as an interesting approach for antiepileptogenic therapies could not be ruled out.', 'Epilepsien gehören zu den häufigsten chronischen neurologischen Erkrankungen des zentralen Nervensystems bei Mensch und Tier. Trotz der Entwicklung zahlreicher neuer Antiepileptika in den letzten Jahrzehnten stellen eine persistierende Pharmakoresistenz von mehr als 30 % beim Menschen und sogar mehr als 50 % beim Hund sowie Nebenwirkungen weiterhin ein großes Problem dar. Einer solchen lediglich symptomatischen und lebenslangen Behandlung mit ungewissem Erfolg wäre eine transiente antiepileptogene Therapie zur Unterdrückung der Epilepsieentstehung in der Latenzzeit zwischen Hirninsult und dem Auftreten erster spontaner Anfälle vorzuziehen. Da epileptogene Prozesse bis dato jedoch kaum verstanden sind, ist eine antiepileptogene Therapie nicht möglich und stellt einen der aktuell wichtigsten Forschungsaspekte in der Epileptologie dar. Das zentrale cholinerge System stellt in diesem Zusammenhang ein bisher wenig erforschtes neurochemisches Netzwerk dar, da es zu Gunsten vom wichtigsten erregenden Neurotransmitter Glutamat und wichtigsten hemmenden Neurotransmitter g-Aminobuttersäure (GABA) in den Hintergrund geriet.

3A1049262220.jsonld | ['Kastrationsfolgen beim Hund in Abhängigkeit von Alter, Größe, Gewicht und Rasse'] | [['The aim of the following thesis was to examine the effects of neutering dogs like urinary incontinence, hypothyroidism and orthopedic problems depending of their age, size, body weight and breed. For this purpose, 6686 questions have been evaluated. The data of 3497 female and 3189 male dogs have been analyzed. 56,1 percent of the bitches and 43,9 percent of the males were castrated. The dogs belonged to 205 different breeds. There has been a connection between the occurrence of urinary incontinence and the reproduction status, the size, the body weight and the breed of the dogs. There was no relationship between the occurrence of urinary incontinence and the early or late neutering in bitches and male dogs. In 11,2 percent of the spayed bitches and 4,7 percent of the castrated males occurred urinary incontinence. 245 of the female dogs with urinary incontinence, 93 percent were spayed and 7 percent intact. The neutered female dogs had a 9,7 times higher risk and the male dogs a 1,7 higher risk to suffer from urinary incontinence than intact dogs. 20,0 percent of the male dogs which had been castrated late, at an age over eight years suffered from urinary incontinence. In female dogs of a shoulder height of over 40 centimeters there had a 12,6 percent higher risk to suffer from urinary incontinence than in spayed bitches of a shoulder height of under 40 centimeters with only 5,4 percent of incidences of urinary incontinence. The risk of urinary incontinence in spayed female dogs increases with increasing seize of the dogs. Spayed female dogs of over 60 centimeters shoulder height suffered 9,8 more often from urinary incontinence than not spayed female dogs of the same height. Spayed female dogs with a weight of over 20 kilograms suffered 16 times more of urinary incontinence (14,4 percent) than not spayed females with 0,9 percent and a weight of over 20 kilograms. In the weight range “20 to 30 kilograms body weight” even 23,6 times as much spayed female dogs suffered from urinary incontinence than intact ones. Certain breed dispositions for urinary incontinence can be identified in spayed female dogs for the breeds Bull Terrier, Giant schnauzer and the Dogue de Bordeaux and for the breed groups pinscher and Schnauzer (25,9 percent), pointing dogs (19,2 percent) and Molossoid breeds (15,6 percent). For the evaluation of hypothyroidism as a side effect of neutering, 324 dogs were found who suffered from it. There has been a connection between the occurrence of hypothyroidism and the reproduction status, the age, the size, the body weight and the breed of the dogs. Castrated male dogs were 7,7 percent more often affected by the disease than spayed bitches with 5,5 percent. In every range of age, neutered male dogs and female dogs were more often affected by hypothyroidism than intact ones, except the group of males of the age between 9 and 12 years. The risk of hypothyroidism increased in bitches and male dogs with increasing age, size and body weight. A breed predisposition can be identified for the Rhodesian Ridgeback (21,8 percent), the Magyar Vizsla (16,6 percent) and the Dobermann (12,2 percent). For the evaluation of the orthopedic problems as the secondary effect of neutering, 1209 dogs were found who suffered from it. There has been a connection between the occurrence of orthopedic problems depending of the reproduction status and the breed of the dogs. The neutered female dogs hat a 3,0 times higher risk and the male dogs a 1,8 higher risk to suffer than intact dogs. Breed predispositions can be recognized in spayed bitches for the Swiss Mountain/Cattle Dogs (43,2 percent), for the Molossoid (38,3 percent) as well as for crossbreeds (31,2 percent) with a body weight above 20 kilograms. The recommendation can be made to castrate the male dog shortly after puberty, if a medical indication exists, because the risk of urinary incontinence increases to 20 percent for the late neutered dogs with increasing age. In view of the present results there can be made no recommendation for neutering of Giant Schnauzer, because 45,0 percent of the female dogs and 28,6 percent of the males of all neutered animals suffered from urinary incontinence. Summarizing the above, it can be stated that during the consultation the owner of the dog should be fully informed about possible unwanted side effects of the neutering. Advantages and disadvantages should be discussed and the reason for the neutering should be identified. The breed, the sex, the age and the body weight of the dog have to be taken into account. It remains a decision for the individual animal. Possible alternatives like the chemical castration via an injectable hormone implant (Suprelorin®) should as well be considered in case of neutering a male dog.', 'Ziel der vorliegenden Arbeit war es, die Kastrationsfolgen Harninkontinenz, Hypothyreose und Probleme mit dem Bewegungsapparat beim Hund in Abhängigkeit von Alter, Größe, Gewicht und Rasse zu untersuchen.

Die Hunde gehörten 205 verschiedenen Rassen an. Es bestanden Zusammenhänge zwischen dem Auftreten von Harninkontinenz und dem Reproduktionsstatus, der Größe, dem Gewicht und Rasse der Hunde. Es bestand kein Zusammenhang zwischen dem Auftreten von Harninkontinenz und einer Früh- oder Spätkastration bei Hündinnen und Rüden. Bei 11,2 % der kastrierten Hündinnen und 4,7 % der kastrierten Rüden trat Harninkontinenz auf. Von den 245 inkontinenten Hündinnen waren 93 % kastriert und 7 % intakt. Kastrierte Hündinnen hatten ein 9,7-fach und kastrierte Rüden ein 1,7-fach erhöhtes Risiko an Harninkontinenz zu erkranken als intakte Hunde. Rüden welche mit über acht Jahren spätkastriert wurden, zeigten zu 20,0 % Harnträufeln. Hündinnen über 40 cm Schulterhöhe hatten mit 12,6 % Erkrankungen ein 2,3-fach höheres Risiko, an Harninkontinenz zu erkranken als kastrierte Hündinnen unter 40 cm Schulterhöhe mit nur 5,4 % Erkrankungsfällen. Das Risiko für kastrierte Hündinnen an Harninkontinenz zu erkranken, stieg mit zunehmender Größe an.

### Title: ['Kastrationsfolgen beim Hund in Abhängigkeit von Alter, Größe, Gewicht und Rasse']
### Abstract:
[['The aim of the following thesis was to examine the effects of neutering dogs like urinary incontinence, hypothyroidism and orthopedic problems depending of their age, size, body weight and breed. For this purpose, 6686 questions have been evaluated. The data of 3497 female and 3189 male dogs have been analyzed. 56,1 percent of the bitches and 43,9 percent of the males were castrated. The dogs belonged to 205 different breeds. There has been a connection between the occurrence of urinary incontinence and the reproduction status, the size, the body weight and the breed of the dogs. There was no relationship between the occurrence of urinary incontinence and the early or late neutering in bitches and male dogs. In 11,2 percent of the spayed bitches and 4,7 percent of the castrated males occurred urinary incontinence. 245 of the female dogs with urinary incontinence, 93 percent were spayed and 7 percent intact. The neutered female dogs had a 9,7 times higher risk and the male dogs a 1,7 higher risk to suffer from urinary incontinence than intact dogs. 20,0 percent of the male dogs which had been castrated late, at an age over eight years suffered from urinary incontinence. In female dogs of a shoulder height of over 40 centimeters there had a 12,6 percent higher risk to suffer from urinary incontinence than in spayed bitches of a shoulder height of under 40 centimeters with only 5,4 percent of incidences of urinary incontinence. The risk of urinary incontinence in spayed female dogs increases with increasing seize of the dogs. Spayed female dogs of over 60 centimeters shoulder height suffered 9,8 more often from urinary incontinence than not spayed female dogs of the same height. Spayed female dogs with a weight of over 20 kilograms suffered 16 times more of urinary incontinence (14,4 percent) than not spayed females with 0,9 percent and a weight of over 20 kilograms. In the weight range “20 to 30 kilograms body weight” even 23,6 times as much spayed female dogs suffered from urinary incontinence than intact ones. Certain breed dispositions for urinary incontinence can be identified in spayed female dogs for the breeds Bull Terrier, Giant schnauzer and the Dogue de Bordeaux and for the breed groups pinscher and Schnauzer (25,9 percent), pointing dogs (19,2 percent) and Molossoid breeds (15,6 percent). For the evaluation of hypothyroidism as a side effect of neutering, 324 dogs were found who suffered from it. There has been a connection between the occurrence of hypothyroidism and the reproduction status, the age, the size, the body weight and the breed of the dogs. Castrated male dogs were 7,7 percent more often affected by the disease than spayed bitches with 5,5 percent. In every range of age, neutered male dogs and female dogs were more often affected by hypothyroidism than intact ones, except the group of males of the age between 9 and 12 years. The risk of hypothyroidism increased in bitches and male dogs with increasing age, size and body weight. A breed predisposition can be identified for the Rhodesian Ridgeback (21,8 percent), the Magyar Vizsla (16,6 percent) and the Dobermann (12,2 percent). For the evaluation of the orthopedic problems as the secondary effect of neutering, 1209 dogs were found who suffered from it. There has been a connection between the occurrence of orthopedic problems depending of the reproduction status and the breed of the dogs. The neutered female dogs hat a 3,0 times higher risk and the male dogs a 1,8 higher risk to suffer than intact dogs. Breed predispositions can be recognized in spayed bitches for the Swiss Mountain/Cattle Dogs (43,2 percent), for the Molossoid (38,3 percent) as well as for crossbreeds (31,2 percent) with a body weight above 20 kilograms. The recommendation can be made to castrate the male dog shortly after puberty, if a medical indication exists, because the risk of urinary incontinence increases to 20 percent for the late neutered dogs with increasing age. In view of the present results there can be made no recommendation for neutering of Giant Schnauzer, because 45,0 percent of the female dogs and 28,6 percent of the males of all neutered animals suffered from urinary incontinence. Summarizing the above, it can be stated that during the consultation the owner of the dog should be fully informed about possible unwanted side effects of the neutering. Advantages and disadvantages should be discussed and the reason for the neutering should be identified. The breed, the sex, the age and the body weight of the dog have to be taken into account. It remains a decision for the individual animal. Possible alternatives like the chemical castration via an injectable hormone implant (Suprelorin®) should as well be considered in case of neutering a male dog.', 'Ziel der vorliegenden Arbeit war es, die Kastrationsfolgen Harninkontinenz, Hypothyreose und Probleme mit dem Bewegungsapparat beim Hund in Abhängigkeit von Alter, Größe, Gewicht und Rasse zu untersuchen.

This unique, structurally complex biological interface is of great scientific interest as it mediates the interaction of bacteria with neighboring bacteria in colonies and biofilms. The interaction between polymer-decorated surfaces is generally coupled to the distance-dependent conformation of the polymer chains. Therefore, structural insight into the interacting surfaces is a prerequisite to understand the interaction characteristics as well as the underlying physical mechanisms. This problem has been addressed by theory, but accurate experimental data on polymer conformations under confinement are rare, because obtaining perturbation-free structural insight into buried soft interfaces is inherently…']
