  abstract  = {Menschen und Rabenv{\"o}gel teilen eine lange gemeinsame Kulturgeschichte. Wer hierbei den Anfang gemacht hat, ist schwer zu sagen. Fest steht aber, dass beide Spezies einander in mancherlei Hinsicht verbl{\"u}ffend {\"a}hnlich sind, und dass nicht nur Menschen V{\"o}gel beobachten, sondern auch umgekehrt. {\"U}ber teilnehmende Beobachtung und zahlreiche Interviews mit Menschen, die regelm{\"a}ßig Rabenv{\"o}gel beobachten oder sie im Rahmen der Wildvogelhilfe pflegen, werden die unterschiedlichen Beschaffenheiten von Mensch-Rabenvogel-Beziehungen aufgezeigt. Dabei wird nach spezies{\"u}bergreifenden F{\"u}rsorgepraktiken, Wissensaushandlungen und ethischen Diskursen gleichermaßen gefragt. Wie wichtig sind haptische und emotionale Ber{\"u}hrungen bei der Pflege verletzter Kr{\"a}hen? Wie sind historisch-mythologische Bilder {\"u}ber Raben und Kr{\"a}hen in den Diskurs um Multispezies-Gemeinschaften zwischen Menschen und Rabenv{\"o}geln einzuordnen? Welches Potenzial k{\"o}nnten Mensch-Rabenvogel-Beziehungen f{\"u}r die verhaltensbiologische Forschung haben? Vor dem Hintergrund der Multispecies Studies werden Raben und Kr{\"a}hen als Akteur*innen verstanden, die mit Handlungs- und Wirkmacht (agency) ausgestattet sind. Ebenso wie die menschlichen Individuen sind sie dazu f{\"a}hig, sich in andere Lebewesen, in Dinge und Orte einzuschreiben. Ziel der Studie ist es, Rabenv{\"o}gel neu zu denken und ebenso Menschen in Verbindung mit Rabenv{\"o}geln neu zu denken, um dadurch den Tieren letztlich auf eine neue Art und Weise zu begegnen.},

Damit sollen die Studien zum contrapunto alla mente aus den letzten Jahren, die neues Licht auf dieses Ph{\"a}nomen geworfen haben, um einen Bereich erweitert werden, der bis jetzt wenig Beachtung gefunden hat: die weitere Entwicklung des improvisierten Kontrapunktes in Spanien bis ins 18. Jahrhundert. Dadurch er{\"o}ffnen sich neue Perspektiven f{\"u}r das Verst{\"a}ndnis der spanischen Musikkultur des Barockzeitalters. Zu den expliziten Informationen aus den Quellen, die bereits zug{\"a}nglich gemacht worden sind, soll ein Teil des implizites Wissens hinzutreten, das in den Contrapunto-Lehren - insbesondere in den Notenbeispielen - eingefangen ist. Die vorliegende Arbeit ist also ein Versuch, dieses implizite Wissen freizusetzen. Auch wenn die tats{\"a}chlich erklungenen Improvisationen nicht konkret rekonstruierbar sind, l{\"a}sst sich die Methodik, mit der professionelle Kontrapunktisten ausgebildet wurden, anhand der Contrapunto-Lehren gut nachvollziehen. Im Kern der Dissertation steht eine vergleichende Untersuchung der Quellen, die versucht, Antworten auf eine zentrale Frage zu finden: Nach welchen Methoden und Techniken hat man in Spanien um 1700 gelernt, Kontrapunkt zu improvisieren?},

  abstract  = {Die Corona-Krise stellt eine der gr{\"o}ßten Herausforderungen in der Geschichte der EU dar. Aufgrund der geringen Kompetenzen der EU im Gesundheitsbereich liegt die Pandemiebek{\"a}mpfung fast ausschließlich in den H{\"a}nden der Mitgliedstaaten. Diese reagierten jedoch zun{\"a}chst mit „nationalen Reflexen" und unsolidarischem Verhalten. Erst nach {\"U}berwindung des ersten Schocks im Fr{\"u}hjahr 2020 konnte die EU sichtbarer bei der Krisenbew{\"a}ltigung werden. Den H{\"o}hepunkt stellte die Einigung auf das historische 750 Mrd. EUR schwere Corona-Hilfspaket „Next Generation EU" (NGEU) dar, welches mit einer gemeinsamen Schuldenaufnahme einen Pr{\"a}zedenzfall geschaffen hat. Diese Arbeit untersucht, wie die EU auf die Pandemie reagiert hat und ob diese Reaktion zu ihrer St{\"a}rkung f{\"u}hren kann. Sie soll einen Beitrag zum besseren Verst{\"a}ndnis der Geschehnisse in der EU zwischen Januar 2020 und Mai 2021 leisten. Hierf{\"u}r werden zun{\"a}chst die Kompetenzen der EU im Gesundheitsbereich und beim Katastrophenschutz sowie deren Nutzung in der Pandemie aufgezeigt. Hauptteil der Arbeit ist die Untersuchung von Entstehung und Inhalt des NGEU-Hilfspaktes. Hier zeigt sich, dass die EU - mit Hilfe des deutsch-franz{\"o}sischen Motors - zur Solidarit{\"a}t zur{\"u}ckgefunden hat. Die Schwerpunktsetzung von NGEU verdeutlicht, dass neben dem Wiederaufbau auch die aktuellen Kernthemen der EU - Digitalisierung und Klimaschutz - einen zentralen Stellenwert einnehmen. Damit kann NGEU zur wesentlichen St{\"a}rkung der EU beitragen. Eine St{\"a}rkung ist ebenfalls im Gesundheitsbereich festzustellen, wo erste Schritte zu einer Gesundheitsunion vollzogen wurden.},

  abstract  = {Die Zielsetzung der vorliegenden Studie war es, die New Wundartzney von Johannes Beris (in der Ausgabe aus dem Verlag Hermann G{\"u}lferich aus Frankfurt am Main von 1552) anhand einer Strukturvorgabe aufzubereiten, so wie Ralf Vollmuth sie in seiner Traumatologie und Feldchirurgie an der Wende vom Mittelalter zur Neuzeit erarbeitet hat. Der Hintergrund f{\"u}r die Analyse und Aufarbeitung mittel¬alter¬lich-fr{\"u}hneuzeitlicher wund{\"a}rztlicher Quellen nach einer Strukturvorgabe ist, eine wissenschaftliche Vergleichbarkeit herzustellen und folglich den Stand der zeitgen{\"o}ssischen medizinischen und pharma¬zeutischen Bildung aufzuzeigen. Die einseitige Rezeption nur der Werke, die eine zahlreiche Auflage erlebten und demnach weit verbreitet und leicht zug{\"a}nglich waren, ergibt ein verzerrtes Bild des chirurgischen Wissensstands dieser Zeit. Die Struktur des Originaltexts wurde durchbrochen und die erarbeiteten Informationen an die neue, f{\"u}r einen Vergleich geeignete Struktur angepasst. In diesem Rahmen wurden auch die zahlreichen Wiederholungen von Behand¬lungs¬ans{\"a}tzen im Original eingek{\"u}rzt. Diese lassen sich in der Quelle auf die Struktur der Darstellung nach K{\"o}rperregionen zur{\"u}ckf{\"u}hren und auf die Tatsache, dass zahlreiche Ans{\"a}tze f{\"u}r mehrere Regionen gleich sind und daher immer wieder erneut vom Verfasser beschrieben werden. In dieser Arbeit werden sie genannt und bei Wiederholung auf die Erstnennung verwiesen. Leider liefert Beris keine aussagekr{\"a}ftigen Informationen {\"u}ber das Instrumentarium und die chirurgischen Techniken seiner Zeit, sondern beschr{\"a}nkt sich auf die wesent¬li¬chen Aspekte der Behandlung, die sich in vielen F{\"a}llen sinngem{\"a}ß oder fast w{\"o}rtlich wiederholen. Dies ist jedoch in Anbetracht der Art seiner Schrift, n{\"a}mlich eines Manuals f{\"u}r seine Sch{\"u}ler, verst{\"a}ndlich: Er setzt beim Leser Grund¬wissen voraus, was sich im Werk an einem Mangel an Grundlageninformationen wider¬spiegelt. Betrachtet man die New Wundarztney, liefert Beris nur wenige innovative Punkte neben der Hygiene und Sauberkeit am Arbeitsplatz des Wundarztes. Auf Sauberkeit zu achten, mahnt er vor allem bei der Ver¬wen¬dung der pharmazeutischen Bestandteile bei der Herstellung der Salben an. Wei¬ter¬hin lehnt er das erneute Brechen von nicht korrekt positionierten und damit disloziert verheilten Br{\"u}chen ab, ebenso das chirurgische Entfernen von Pfeilspitzen; er f{\"u}hrt so selten wie m{\"o}glich eine chirurgische Adaptation der Wundr{\"a}nder aus und l{\"a}sst Pflaster {\"u}ber Tage hinweg ruhen mit dem Hinweis auf bessere Wundheilung bei Ent¬z{\"u}ndungsfreiheit. Ansonsten entsprechen seine Ausf{\"u}hrungen dem Stand der Zeit und klassifizieren Beris als Vertreter von unblutigen Therapien. Die Tatsache, dass die New Wundartzney keine Bildtafeln aufweist, tr{\"u}bt ein wenig das Erscheinungsbild der Quelle, obwohl Bildtafeln in der damaligen Zeit, beispielsweise in gedruckten Handb{\"u}chern zur Anatomie und Chirurgie, durchaus {\"u}blich waren. Dieses l{\"a}sst sich darauf zur{\"u}ckf{\"u}hren, dass hier {\"u}berwiegend Rezepte und Behandlungs¬maßnah¬men f{\"u}r die eigenen Sch{\"u}ler geschildert werden und es sich bei dem Manual um eine wissen¬schaft¬lich eher kleine Schrift handelt. Insgesamt betrachtet kann somit festgehalten werden, dass die Schrift von Beris nur wenig innovatives Wissen vermittelt. Ihren Anspruch, dem damaligen Wundarzt als praxisorientierte Anleitung zur Behandlung von Wunden und zur Herstellung von Pflastern und Wundtr{\"a}nken zu dienen, erf{\"u}llt sie jedoch voll und ganz. Viel detaillierter hingegen sind die Rezepte in der New Wundartzney, die nicht von Beris selbst stammen und die der Verleger, wie oben erw{\"a}hnt, als Wissens¬erweite¬rung eingegliedert hat. Der von Ralf Vollmuth begonnene Katalog von Drogenmonographien konnte anhand der New Wundartzney um 32 neu erarbeitete Beitr{\"a}ge erg{\"a}nzt werden. Die restlichen 47 der 79 Monographien wurden anhand aktueller Ver{\"o}ffentlichungen verifiziert und wenn notwendig aktualisiert oder erg{\"a}nzt. Sie stehen damit einer weiteren wissen¬schaft¬lichen Verwen¬dung zur Verf{\"u}gung. Zum profunderen Studium der Quelle und zur Erg{\"a}nzung der Arbeit mit einer neuen aktualisierten Textfassung findet man in Kapitel 6 eine Transkription der New Wundartzney. Die vorliegende Arbeit soll als ein erg{\"a}nzender Baustein in der Aufarbeitung der sp{\"a}t¬mit¬tel-alterlich-fr{\"u}hneuzeitlichen chirurgischen Quellen und als Beitrag zu einem sp{\"a}¬te¬ren kritischen Vergleich weiterer Quellen dienen.},

  abstract  = {The 1,3-bis(tricyanoborane)imidazolate anion 1 was obtained in high yield from lithium imidazolate and B(CN)\(_3\)-pyridine adduct. Anion 1 is chemically very robust and thus allowed the isolation of the corresponding H\(_5\)O\(_2\)\(^+\) salt. Furthermore, monoanion 1 served as starting species for the novel dianionic N-heterocyclic carbene (NHC), 1,3-bis(tricyanoborane)imidazoline-2-ylidenate anion 3 that acts as ditopic ligand via the carbene center and the cyano groups at boron. First reactions of this new NHC 3 with methyl iodide, elemental selenium, and [Ni(CO)\(_4\)] led to the methylated imidazolate ion 4, the dianionic selenium adduct 5, and the dianionic nickel tricarbonyl complex 6. These NHC derivatives provide a first insight into the electronic and steric properties of the dianionic NHC 3. Especially the combination of properties, such as double negative charge, different coordination sites, large buried volume and good σ-donor and π-acceptor ability, make NHC 3 a unique and promising ligand and building block.},

Upon methylation or protonation, the emission maxima are significantly bathochromically shifted compared to the neutral compounds, although the absorption maxima remain almost unchanged. As a result, the cationic compounds show very large apparent Stokes shifts of up to 7200 cm\(^{-1}\). The N-methylpyridinium compounds have a single reduction at ca. -1.5 V vs. Fc/Fc\(^+\) in MeCN. While the reduction process was reversible for the 2,7-disubstituted compound, it was irreversible for the mono-substituted one. Experimental findings are complemented by DFT and TD-DFT calculations. Furthermore, the N-methylpyridinium compounds show strong interactions with calf thymus (ct)-DNA, presumably by intercalation, which paves the way for further applications of these multi-functional compounds as potential DNA-bioactive agents.},

Malignant tumors of the salivary glands are challenging in terms of differentiation because of their variability in histochemistry and translocations.

  abstract  = {Growth, ageing and atherosclerotic plaque development alter the biomechanical forces acting on the vessel wall. However, monitoring the detailed local changes in wall shear stress (WSS) at distinct sites of the murine aortic arch over time has been challenging. Here, we studied the temporal and spatial changes in flow, WSS, oscillatory shear index (OSI) and elastic properties of healthy wildtype (WT, n = 5) and atherosclerotic apolipoprotein E-deficient (Apoe\(^{-/-}\), n = 6) mice during ageing and atherosclerosis using high-resolution 4D flow magnetic resonance imaging (MRI). Spatially resolved 2D projection maps of WSS and OSI of the complete aortic arch were generated, allowing the pixel-wise statistical analysis of inter- and intragroup hemodynamic changes over time and local correlations between WSS, pulse wave velocity (PWV), plaque and vessel wall characteristics. The study revealed converse differences of local hemodynamic profiles in healthy WT and atherosclerotic Apoe\(^{-/-}\) mice, and we identified the circumferential WSS as potential marker of plaque size and composition in advanced atherosclerosis and the radial strain as a potential marker for vascular elasticity. Two-dimensional (2D) projection maps of WSS and OSI, including statistical analysis provide a powerful tool to monitor local aortic hemodynamics during ageing and atherosclerosis. The correlation of spatially resolved hemodynamics and plaque characteristics could significantly improve our understanding of the impact of hemodynamics on atherosclerosis, which may be key to understand plaque progression towards vulnerability.},

However, the role of 5-HTT deficiency on cardiac aging, and on healing and remodeling processes after myocardial infarction (MI), remains unclear. Cardiological evaluation of experimentally na{\"i}ve male mice revealed a mild cardiac dysfunction in ≥4-month-old 5-HTT knockout (-/-) animals. Following induction of chronic cardiac dysfunction (CCD) by MI vs. sham operation 5-HTT-/- mice with infarct sizes >30\% experienced 100\% mortality, while 50\% of 5-HTT+/- and 37\% of 5-HTT+/+ animals with large MI survived the 8-week observation period. Surviving (sham and MI < 30\%) 5-HTT-/- mutants displayed reduced exploratory activity and increased anxiety-like behavior in different approach-avoidance tasks. However, CCD failed to provoke a depressive-like behavioral response in either 5-Htt genotype. Mechanistic analyses were performed on mice 3 days post-MI. Electrocardiography, histology and FACS of inflammatory cells revealed no abnormalities. However, gene expression of inflammation-related cytokines (TGF-β, TNF-α, IL-6) and MMP-2, a protein involved in the breakdown of extracellular matrix, was significantly increased in 5-HTT-/- mice after MI. This study shows that 5-HTT deficiency leads to age-dependent cardiac dysfunction and disrupted early healing after MI probably due to alterations of inflammatory processes in mice.},

Non-invasive cell tracking can provide an important opportunity to monitor in vivo cell distribution in living subjects. Here, using a combination of positron emission tomography (PET) and in vitro 2-deoxy-2-[18F]fluoro-D-glucose ([18F]FDG) direct cell labelling, the feasibility of engrafted stem cell monitoring was tested in multiple animal species. Human mesenchymal stem cells (MSCs) were incubated with phosphate-buffered saline containing [18F]FDG for in vitro cell radiolabelling. The pre-labelled MSCs were administrated via peripheral vein in a mouse (n=1), rats (n=4), rabbits (n=4) and non-human primates (n=3), via carotid artery in rats (n=4) and non-human primates (n=3), and via intra-myocardial injection in rats (n=5). PET imaging was started 10 min after cell administration using a dedicated small animal PET system for a mouse and rats. A clinical PET system was used for the imaging of rabbits and non-human primates. After MSC administration via peripheral vein, PET imaging revealed intense radiotracer signal from the lung in all tested animal species including mouse, rat, rabbit, and non-human primate, suggesting administrated MSCs were trapped in the lung tissue. Furthermore, the distribution of the PET signal significantly differed based on the route of cell administration. Administration via carotid artery showed the highest activity in the head, and intra-myocardial injection increased signal from the heart. In vitro [18F]FDG MSC pre-labelling for PET imaging is feasible and allows non-invasive visualization of initial cell distribution after different routes of cell administration in multiple animal models. Those results highlight the potential use of that imaging approach for the understanding and optimization of stem cell therapy in translational research.},

The current gold standard for studying burn wounds are animal models, which are under criticism due to ethical considerations and a limited predictiveness. Here, we present a three-dimensional burn model, based on an open-source model, to monitor wound healing on the epidermal level. Skin equivalents were burned, using a preheated metal cylinder. The healing process was monitored regarding histomorphology, metabolic changes, inflammatory response and reepithelialization for 14 days. During this time, the wound size decreased from 25\% to 5\% of the model area and the inflammatory response (IL-1β, IL-6 and IL-8) showed a comparable course to wounding and healing in vivo. Additionally, the topical application of 5\% dexpanthenol enhanced tissue morphology and the number of proliferative keratinocytes in the newly formed epidermis, but did not influence the overall reepithelialization rate. In summary, the model showed a comparable healing process to in vivo, and thus, offers the opportunity to better understand the physiology of thermal burn wound healing on the keratinocyte level.},

Homozygosity mapping followed by exome sequencing identified a 14.96 Mb locus on chromosome 4p15.32p15.1 containing a likely pathogenic missense variant in CLRN2 (c.494C > A, NM_001079827.2) segregating with the disease. Using in vitro RNA splicing analysis, we show that the CLRN2 c.494C > A variant leads to two events: (1) the substitution of a highly conserved threonine (uncharged amino acid) to lysine (charged amino acid) at position 165, p.(Thr165Lys), and (2) aberrant splicing, with the retention of intron 2 resulting in a stop codon after 26 additional amino acids, p.(Gly146Lysfs*26). Expression studies and phenotyping of newly produced zebrafish and mouse models deficient for clarin 2 further confirm that clarin 2, expressed in the inner ear hair cells, is essential for normal organization and maintenance of the auditory hair bundles, and for hearing function. Together, our findings identify CLRN2 as a new deafness gene, which will impact future diagnosis and treatment for deaf patients.},

  abstract  = {Evolution has endowed the lung with exceptional design providing a large surface area for gas exchange area (ca. 100 m\(^{2}\)) in a relatively small tissue volume (ca. 6 L). This is possible due to a complex tissue architecture that has resulted in one of the most challenging organs to be recreated in the lab. The need for realistic and robust in vitro lung models becomes even more evident as causal therapies, especially for chronic respiratory diseases, are lacking. Here, we describe the Cyclic In VItro Cell-stretch (CIVIC) "breathing" lung bioreactor for pulmonary epithelial cells at the air-liquid interface (ALI) experiencing cyclic stretch while monitoring stretch-related parameters (amplitude, frequency, and membrane elastic modulus) under real-time conditions. The previously described biomimetic copolymeric BETA membrane (5 μm thick, bioactive, porous, and elastic) was attempted to be improved for even more biomimetic permeability, elasticity (elastic modulus and stretchability), and bioactivity by changing its chemical composition. This biphasic membrane supports both the initial formation of a tight monolayer of pulmonary epithelial cells (A549 and 16HBE14o\(^{-}\)) under submerged conditions and the subsequent cell-stretch experiments at the ALI without preconditioning of the membrane. The newly manufactured versions of the BETA membrane did not improve the characteristics of the previously determined optimum BETA membrane (9.35\% PCL and 6.34\% gelatin [w/v solvent]). Hence, the optimum BETA membrane was used to investigate quantitatively the role of physiologic cyclic mechanical stretch (10\% linear stretch; 0.33 Hz: light exercise conditions) on size-dependent cellular uptake and transepithelial transport of nanoparticles (100 nm) and microparticles (1,000 nm) for alveolar epithelial cells (A549) under ALI conditions. Our results show that physiologic stretch enhances cellular uptake of 100 nm nanoparticles across the epithelial cell barrier, but the barrier becomes permeable for both nano- and micron-sized particles (100 and 1,000 nm). This suggests that currently used static in vitro assays may underestimate cellular uptake and transbarrier transport of nanoparticles in the lung.},

  abstract  = {Chronic respiratory diseases are among the leading causes of death worldwide, but only symptomatic therapies are available for terminal illness. This in part reflects a lack of biomimetic in vitro models that can imitate the complex environment and physiology of the lung. Here, a copolymeric membrane consisting of poly(ε-)caprolactone and gelatin with tunable properties, resembling the main characteristics of the alveolar basement membrane is introduced. The thin bioinspired membrane (≤5 μm) is stretchable (up to 25\% linear strain) with appropriate surface wettability and porosity for culturing lung epithelial cells under air-liquid interface conditions. The unique biphasic concept of this membrane provides optimum characteristics for initial cell growth (phase I) and then switch to biomimetic properties for cyclic cell-stretch experiments (phase II). It is showed that physiologic cyclic mechanical stretch improves formation of F-actin cytoskeleton filaments and tight junctions while non-physiologic over-stretch induces cell apoptosis, activates inflammatory response (IL-8), and impairs epithelial barrier integrity. It is also demonstrated that cyclic physiologic stretch can enhance the cellular uptake of nanoparticles. Since this membrane offers considerable advantages over currently used membranes, it may lead the way to more biomimetic in vitro models of the lung for translation of in vitro response studies into clinical outcome.},

  abstract  = {The cell—cell signaling gene CDH13 is associated with a wide spectrum of neuropsychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD), autism, and major depression. CDH13 regulates axonal outgrowth and synapse formation, substantiating its relevance for neurodevelopmental processes. Several studies support the influence of CDH13 on personality traits, behavior, and executive functions. However, evidence for functional effects of common gene variation in the CDH13 gene in humans is sparse. Therefore, we tested for association of a functional intronic CDH13 SNP rs2199430 with ADHD in a sample of 998 adult patients and 884 healthy controls. The Big Five personality traits were assessed by the NEO-PI-R questionnaire. Assuming that altered neural correlates of working memory and cognitive response inhibition show genotype-dependent alterations, task performance and electroencephalographic event-related potentials were measured by n-back and continuous performance (Go/NoGo) tasks. The rs2199430 genotype was not associated with adult ADHD on the categorical diagnosis level. However, rs2199430 was significantly associated with agreeableness, with minor G allele homozygotes scoring lower than A allele carriers. Whereas task performance was not affected by genotype, a significant heterosis effect limited to the ADHD group was identified for the n-back task. Heterozygotes (AG) exhibited significantly higher N200 amplitudes during both the 1-back and 2-back condition in the central electrode position Cz. Consequently, the common genetic variation of CDH13 is associated with personality traits and impacts neural processing during working memory tasks. Thus, CDH13 might contribute to symptomatic core dysfunctions of social and cognitive impairment in ADHD.},

  abstract  = {The greatest problems faced during the 21st century is climate change which is a big threat to food security due to increasing number of people. The increase in extreme weather events, such as drought and heat, makes it difficult to cultivate conventional crops that are not stress tolerant. As a result, increasing irrigation of arable land leads to additional salinization of soils with plant-toxic sodium and chloride ions. Knowledge about the adaptation strategies of salt-tolerant plants to salt stress as well as detailed knowledge about the control of transpiration water loss of these plants are therefore important to guarantee productive agriculture in the future. In the present study, I have characterized salt sensitive and salt tolerant plant species at physiological, phenotypic and transcriptomic level under short (1x salt) and long-time (3x) saline growth conditions. Two approaches used for long-time saline growth conditions (i.e increasing saline conditions (3x salt) and constant high saline conditions (3x 200 mM salt) were successfully developed in the natural plant growth medium i.e soil. Salt sensitive plants, A. thaliana, were able to survive and successfully set seeds at the toxic concentrations on the increasing saline growth mediums, with minor changes in the phenotype. However, under constant high saline conditions they could not survive. This was due to keeping low potassium, and high salt ions (sodium and chloride) in the photosynthetic tissue i.e leaf. Similarly, high potassium and low salt ions in salt tolerant T. salsuginea on both saline environments were the key for survival of this plant species. Being salt tolerant, T. salsuginea always kept high potassium levels and low sodium (during 1x) and chloride levels (during both 1x and 3x) in the leaf tissue. A strict control over transpirational water loss via stomata (formed by pair of guard cells) is important to maintain plant water balance. Aperture size of the stomata is regulated by the turgidity of the guard cells. More turgid the guard cells, bigger the apertures are and hence more transpiration. Under osmotic stress, the water loss is reduced which was evident in the salt sensitive A. thaliana plants under both short and long-time saline growth conditions. As the osmotic stress was only increased during long time saline growth conditions in T. salsuginea therefore, water loss was also decreased only under these saline conditions. Environmental CO2 assimilation also takes place via stomata in plants which then is used for photosynthesis. Stomatal apertures also influence CO2 assimilation. As the light absorbing photosynthetic pigments were more affected in A. thaliana, therefore photosynthetic activity of the whole plant was also reduced. Similarly, both short and long-time saline growth conditions also reduced the effective quantum yield of A. thaliana guard cells. Growth of the plant is dependent on energy which comes from photosynthesis. Reduced environmental CO2 assimilation would affect photosynthesis and hence growth, which was clearly observed in A. thaliana guard cells under long-time saline growth conditions. Major differences in both guard cells types were observed in their chloride and potassium levels. Energy Dispersive X-Ray Analysis (EDXA) suggested strict control of chloride accumulation in T. salsuginea guard cells as the levels remain unchanged under all conditions. Similarly, use of sodium in place of potassium for osmotic adjustments seems to be dependent on Na+/K+ rations in both guard cell types. Increased salt ions and reduced potassium levels in A. thaliana guard cells posed negative effect on photochemistry which in turn increased ROS metabolism and reduced energy related pathways at transcriptomic level in this plant species. Moreover, photosynthesis was strongly affected in A. thaliana guard cells both at transcriptomic and physiological levels. Similarly, global phytohormones induced changes were more evident in A. thaliana guard cells especially on 3x salt medium. Among all phytohormones, genes under the control of auxin were more differentially expressed in A. thaliana guard cells which suggests wide changes in growth and development in this plant species under salinity. Phytohormone, ABA is vital for closing the stomata under abiotic stress conditions. Increased levels of ABA during saline conditions led to efflux of potassium and counter anions (chloride, malate, nitrate) from the guard cells which caused the outward flow of water and hence reduction in turgor pressure. Reduced turgor pressure led to reduced water loss and CO2 assimilation especially in A. thaliana. Guard cells of both plant species synthesized ABA during saline conditions which was reflected from transcriptomic data and ABA quantification in the guard cells. ABA induced signaling in both plant species varied at the ABA receptor (PYL/PYR) levels where totally contrasting responses were observed. PYL2, PYL8 and PYL9 were specific to A. thaliana, furthermore, PYL2 was found to be differentially expressed only under 3x salt growth conditions thus suggesting its role during long term salt stress in this plant species. Protein phosphatases, which negatively regulate ABA signaling on one hand and act as ABA sensor on the other hand were found to be more differentially expressed in A. thaliana than T. salsuginea guard cells, which suggests their diverse role in both plant species under saline conditions. Differential expression of more ABA signaling players in long time saline conditions was prominent which could be because of darkness, as it is well known that rapid closure of stomata under dark conditions require ABA signaling. Moreover, representation of these components in dark also suggests that plants become more sensitive to dark under saline conditions which is also evident from the transpiration rates. Altogether, increased salt ions in A. thaliana guard cells and leaves led to pigment degradation and ABA induced reduction in transpiration which in turn influenced its growth. In contrast, T. salsuginea is the salt excluder and therefore keeps low levels of salt ions especially the chloride both in leaves and guard cells which mildly affects its growth. Guard cells of A. thaliana encounter severe energy problems at physiological and transcriptomic level. Main differences in the ABA signalling between both plant species were observed at the ABA receptor level.},

  abstract  = {Summary Bees, like many other organisms, evolved an endogenous circadian clock, which enables them to foresee daily environmental changes and exactly time foraging flights to periods of floral resource availability. The social lifestyle of a honey bee colony has been shown to influence circadian behavior in nurse bees, which do not exhibit rhythmic behavior when they are nursing. On the other hand, forager bees display strong circadian rhythms. Solitary bees, like the mason bee, do not nurse their offspring and do not live in hive communities, but face the same daily environmental changes as honey bees. Besides their lifestyle mason and honey bees differ in their development and life history, because mason bees overwinter after eclosion as adults in their cocoons until they emerge in spring. Honey bees do not undergo diapause and have a relatively short development of a few weeks until they emerge. In my thesis, I present a comparison of the circadian clock of social honey bees (Apis mellifera) and solitary mason bees (Osmia bicornis and Osmia cornuta) on the neuroanatomical level and behavioral output level. I firstly characterized in detail the localization of the circadian clock in the bee brain via the expression pattern of two clock components, namely the clock protein PERIOD (PER) and the neuropeptide Pigment Dispersing Factor (PDF), in the brain of honey bee and mason bee. PER is localized in lateral neuron clusters (which we called lateral neurons 1 and 2: LN1 and LN2) and dorsal neuron clusters (we called dorsal lateral neurons and dorsal neurons: DLN, DN), many glia cells and photoreceptor cells. This expression pattern is similar to the one in other insect species and indicates a common ground plan of clock cells among insects. In the LN2 neuron cluster with cell bodies located in the lateral brain, PER is co-expressed with PDF. These cells build a complex arborization network throughout the brain and provide the perfect structure to convey time information to brain centers, where complex behavior, e.g. sun-compass orientation and time memory, is controlled. The PDF arborizations centralize in a dense network (we named it anterio-lobular PDF hub: ALO) which is located in front of the lobula. In other insects, this fiber center is associated with the medulla (accessory medulla: AME). Few PDF cells build the ALO already in very early larval development and the cell number and complexity of the network grows throughout honey bee development. Thereby, dorsal regions are innervated first by PDF fibers and, in late larval development, the fibers grow laterally to the optic lobe and central brain. The overall expression pattern of PER and PDF are similar in adult social and solitary bees, but I found a few differences in the PDF network density in the posterior protocerebrum and the lamina, which may be associated with evolution of sociality in bees. Secondly, I monitored activity rhythms, for which I developed and established a device to monitor locomotor activity rhythms of individual honey bees with contact to a mini colony in the laboratory. This revealed new aspects of social synchronization and survival of young bees with indirect social contact to the mini colony (no trophalaxis was possible). For mason bees, I established a method to monitor emergence and locomotor activity rhythms and I could show that circadian emergence rhythms are entrainable by daily temperature cycles. Furthermore, I present the first locomotor activity rhythms of solitary bees, which show strong circadian rhythms in their behavior right after emergence. Honey bees needed several days to develop circadian locomotor rhythms in my experiments. I hypothesized that honey bees do not emerge with a fully matured circadian system in the hive, while solitary bees, without the protection of a colony, would need a fully matured circadian clock right away after emergence. Several indices in published work and preliminary studies support my hypothesis and future studies on PDF expression in different developmental stages in solitary bees may provide hard evidence.},
