description: Electron band topology is combined with intrinsic magnetic orders in MnBi2Te4, leading to novel quantum phases. Here we investigate collective spin excitations (i.e. magnons) and spin ﬂuctuations in atomically thin MnBi2Te4 ﬂakes using Raman spectroscopy. In a two- septuple layer with non-trivial topology, magnon characteristics evolve as an external mag- netic ﬁeld tunes the ground state through three ordered phases: antiferromagnet, canted antiferromagnet, and ferromagnet. The Raman selection rules are determined by both the crystal symmetry and magnetic order while the magnon energy is determined by different interaction terms. Using non-interacting spin-wave theory, we extract the spin-wave gap at zero magnetic ﬁeld, an anisotropy energy, and interlayer exchange in bilayers. We also ﬁnd magnetic ﬂuctuations increase with reduced thickness, which may contribute to a less robust magnetic order in single layers.

description: We analyze the effects of disorder on the correlation functions of one-dimensional quantum models of fermions and spins with long-range interactions that decay with distance $\ell$ as a power-law $1/\ell^α$. Using a combination of analytical and numerical results, we demonstrate that power-law interactions imply a long-distance algebraic decay of correlations within disordered-localized phases, for all exponents $α$. The exponent of algebraic decay depends only on $α$, and not, e.g., on the strength of disorder. We find a similar algebraic localization for wave-functions. These results are in contrast to expectations from short-range models and are of direct relevance for a variety of quantum mechanical systems in atomic, molecular and solid-state physics.

 Notes. – The name Celsia lanceolata has been validated in Descriptions in 1801 based on a Bruguière and Olivier collection from Iraq (between Mosul and Baghdad) and cultivated in Cels’s garden. The specimen in Ventenat’s herbarium from Cels’s garden is designated here as the lectotype with a duplicate in G-BOIS. Four specimens collected between Mosul and Baghdad by Bruguière and Olivier have been located in G-BOIS [G00330748, G00330750] and P [P03287379, P03287380]. They are here considered as elements of original material. Huber-Morath (1981: 25) in his revision of Verbascum L. for Flora Iranica did not cite any type for Celsia lanceolata.

description: The consistency condition, which guarantees a well organized small-coupling asymptotic expansion for the thermodynamics of massless $ϕ^4$-theory, is generalized to any desired order of the perturbative treatment. Based on a strong conjecture about forbidden two-particle reducible diagrams, this condition is derived in terms of functions of four-momentum in place of the common toy mass in previous treatments. It has the form of a set of gap equations and marks the position in the space of these functions at which the free energy is extremal.

description: The ARIANNA experiment aims to detect the radio signals of cosmogenic neutrinos. It is running in its pilot phase on the Ross Ice-shelf, and one station has been installed at South Pole. The ARIANNA concept is based on installing high-gain log periodic dipole antennas close to the surface monitoring the underlying ice for the radio signals following a neutrino interaction. Especially, but not only in this configuration, it is essential to understand the trajectories that the signals take through the ice. We will report on various experimental evidence concerning the signal propagation in ice. We will discuss the implications for neutrino detection, results of neutrino searches and give the first introduction to a new modular simulation framework.

description: The transport properties of the ferromagnetic Kondo lattice model in one dimension are studied via bosonization methods. The antiferromagnetic fluctuations, which normally appear because of the RKKY interactions, are explicitly taken into account as a direct exchange between the ``core'' spins. It is shown that in the paramagnetic regime with the local antiferromagnetic fluctuations, the resistivity decays exponentially as the temperature increases while in the ferromagnetic regime the system is an almost perfect conductor. %A non-perturbative description of localized spin polarons %in the paramagnetic region is obtained. The effect of a weak applied field is discussed to be reduced to the case of the ferromagnetic state leading to band splitting. The qualitative relevance of the results for the problem of the Oxide Manganites is emphasized.

description: In dieser Arbeit wird der Schwerpunkt auf Menschen mit geistiger Behinderung gelegt, die einen Kinderwunsch innerhalb eines Heimsettings hegen. Menschen mit einer geistigen Behinderung werden oft von professionellen Mitarbeitern der Sozialen Arbeit begleitet, um eine höhere Selbstständigkeit zu erreichen. Zur Selbstständigkeit gehört auch das Thema Sexualität. In diesem übergeordneten Thema ist auch der Kinderwunsch enthalten. Jedoch sind viele professionellen der Sozialen Arbeit mit dem Thema Kinderwunsch überfordert und können somit die Klientinnen und Klienten nicht fachgerecht unterstützen und fördern. Die qualitative Forschung hat aufgezeigt, dass bei vielen Institutionen noch Nachholbedarf beim Thema Kinderwunsch besteht. Außerdem müsste ein strukturelles Umdenken geschehen. Die Ergebnisse zeigen, dass es vielen Sozialpädagoginnen und Sozialpädagogen schwer fällt, mit dem Thema umzugehen, unter anderem auch, weil die Angelegenheit in der Gesellschaft noch mit einem grossen Tabu belegt ist. Für die Soziale Arbeit ist die vorliegende Arbeit von Bedeutung, weil sie wichtige theoretische Kenntnisse und deren Verknüpfung zum Arbeitsalltag aufzeigt.

description: We provide new evidence on the role of physical job demands and the physical work environment on retirement outcomes by linking occupation-level data on job requirements from the Occupational Requirements Survey (ORS) to individual-level data from the Health and Retirement Study (HRS). Using alternative strategies to address missing data, and after examining the concurrent validity of ORS job requirements with analogous measures from the Occupational Information Network (O*NET), we create a composite index of physical job demands comprising strenuous physical activities (e.g., lifting and strength) and a composite index of physical work environment comprising hazardous or taxing environmental conditions (e.g. noise, heat). We use these validated indices to estimate associations between job demands and retirement outcomes controlling for observed individual and household characteristics. We find that a one standard deviation increase in our index of physical jobs demands is associated with a 10 percentage point increase in the probability of being retired at any age and a 1.8 percentage point increase in the probability of transitioning into full retirement from full-time work. The same size increase in our physical work environment index is associated with a 7 percentage point increase in the probability of being retired, but it does not provide additional explanatory variation for transitions into retirement. These effects are almost entirely concentrated in men, who hold jobs that are significantly more physically demanding than women’s, and they are also larger among older and less-educated workers.

We show that experimental results for resistivity are qualitatively consistent with numerical simulations that describe the melting of a commensurate rotated lattice. However for some magnetic fields, the structure factor indicates the occurrence of smectic peaks at an intermediate temperature regime.

description: One of the most important members of the Equidae family in today's global culture is Equus asinus. African animals are the ancestors of donkeys (Equus asinus africanus). Over the millennia, asses have expanded over Asia, India, Southern Europe, and the Americas since they were domesticated around 4,000 years before the time of Christ (B.C.) (Mclean and Gonzalez, 2018). Donkeys are one of the ancient domesticated livestock. In developing countries donkeys are valued in particular for their ability to survive under harsh conditions (Bwanga, 2008), yet they are often regarded as animals of low social status and neglected by research and development organizations (Starkey, 1995).

description: We present the analysis of infrared (IR) observations of the planetary nebula NGC 40 together with spectral analysis of its [WC]-type central star HD 826. Spitzer IRS observations were used to produce spectral maps centred at polycyclic aromatic hydrocarbons (PAH) bands and ionic transitions to compare their spatial distribution. The ionic lines show a clumpy distribution of material around the main cavity of NGC 40, with the emission from [Ar II] being the most extended, whilst the PAHs show a rather smooth spatial distribution. Analysis of ratio maps shows the presence of a toroidal structure mainly seen in PAH emission, but also detected in a Herschel PACS 70 mic image. We argue that the toroidal structure absorbs the UV flux from HD 826, preventing the nebula to exhibit lines of high-excitation levels as suggested by previous authors. We discuss the origin of this structure and the results from the spectral analysis of HD 826 under the scenario of a late thermal pulse.

description: Die vorliegende Bachelor-Arbeit befasst sich mit der Frage, wie sich die Soziale Arbeit in der Gestaltung des Sozialraums einbringen kann, damit kinder- und jugendfreundliche Quartiere geschaffen, erhalten oder erweitert werden. Basierend auf Erkenntnissen der gesetzlichen Grundlagen, der Sozialisation und einer entwicklungspsychologischen Perspektive auf Kinder und Jugendliche wird der Fokus dieser Arbeit auf den Sozialraum im Kontext des urbanen Quartiers gelegt. Erläutert wird wie vorteilhafte Entwicklungsbedingungen für Kinder und Jugendliche aussehen und wie diese in die Quartierplanung respektive in die Quartierentwicklung einfliessen und auch in der Praxis umgesetzt werden. Diesbezüglich werden sichere, gut erreichbare, gestaltbare und veränderbare Räume für Kinder und Jugendliche gefordert, welche soziale Beziehungen begünstigen und ein autonomes Erkunden zulassen. Weiter wird der Nutzen einer transdisziplinären Zusammenarbeit und das Zusammenspiel von verschiedenen involvierten Akteuren, welche in einem Quartier agieren, erläutert. Eine zielgruppengerechte Beteiligungsform wird anhand des Arbeitsprinzips «Partizipation» erlangt und ein praxisnaher Bezug wird im letzten Kapitel über die Hauptfunktionen der Soziokulturelle Animation aufgezeigt, womit der Aspekt der Kinder- und Jugendfreundlichkeit zum Tragen kommen soll.

description: The latitudinal distribution of starspots deviates from the solar pattern with increasing rotation rate. Numerical simulations of magnetic flux emergence and transport can help model the observed stellar activity patterns and the associated brightness variations. We set up a composite model for the processes of flux emergence and transport on Sun-like stars, to simulate stellar brightness variations for various levels of magnetic activity and rotation rates. Assuming that the distribution of magnetic flux at the base of the convection zone follows solar scaling relations, we calculate the emergence latitudes and tilt angles of bipolar regions at the surface for various rotation rates, using thin-flux-tube simulations. Taking these two quantities as input to a surface flux transport SFT model, we simulate the diffusive-advective evolution of the radial field at the stellar surface, including effects of active region nesting. As the rotation rate increases, (1) magnetic flux emerges at higher latitudes and an inactive gap opens around the equator, reaching a half-width of $20^\circ$ for $8Ω_\odot$, (2) the tilt angles of freshly emerged bipolar regions show stronger variations with latitude. Polar spots can form at $8Ω_\odot$ by accumulation of follower-polarity flux from decaying bipolar regions. From $4Ω_\odot$ to $8Ω_\odot$, the maximum spot coverage changes from 3 to 20%, respectively, compared to 0.4% for the solar model. Nesting of activity can lead to strongly non-axisymmetric spot distributions. On Sun-like stars rotating at $8Ω_\odot$ ($P_{\rm rot}\simeq 3$ days), polar spots can form, owing to higher levels of flux emergence rate and tilt angles. Defining spots by a threshold field strength yields global spot coverages that are roughly consistent with stellar observations.

description: Possibilities to extract information on the strange form factors of the nucleon from neutrino (antineutrino) inelastic scattering on nuclei, in an energy range from 200 MeV to 1 GeV and more, are investigated in detail. All calculations are performed within two relativistic independent particle models (Fermi gas and shell model); the final state interactions of the ejected nucleon are taken into account through relativistic optical model potentials. We have shown that the values of the cross sections significantly depend on the nuclear model (especially in the lower energy range). However the NC/CC neutrino-antineutrino asymmetry in a medium--high energy range shows a rather small dependence on the model and allows to disentangle different values of the parameters that characterize the strange form factors. We have calculated also the ratio of the cross sections for inelastic NC scattering of neutrinos on nuclei, with the emission of a proton and of a neutron. Our calculations show that this ratio depends rather weakly on the nuclear model and confirm previous conclusions on the rather strong dependence of this ratio upon the axial strange form factors.

description: We measure the persistence exponent in a phase separating two-dimensional spin system with non-conserved dynamics quenched in a region with four coexisting stripe phases. The system is an Ising model with nearest neighbor, next-to-the-nearest neighbor and plaquette interactions. Due the particular nature of the ground states, the order parameter is defined in terms of blocks of spins. Our estimate of the persistence exponent, $θ=0.42$, differs from those of the two-dimensional Ising and four state Potts models. Our procedure allows the study of persistence properties also at finite temperature $T$: our results are compatible with the hypothesis that $θ$ does not depend on $T$ below the critical point.

description: Irradiation is widely used in anticancer therapy; however, the efficiency is limited. Most cancer cells have mutations in apoptosis that they can easily escape the apoptosis induced by irradiation. Autophagy has been known as type II programmed cell death that can be activated by irradiation, especially when apoptosis is blocked, but the underlying molecular mechanism is largely unknown. We demonstrated that proapoptotic genes PUMA and Bid are involved in the regulation of autophagic cell death. When wild-type (WT), Bax− / − and PUMA− / − HCT116 cells were exposed to irradiation, we found that, compared with WT, Bax− / − cells showed significantly decreased cell death because of Bax deficiency; however, surprisingly PUMA− / − cells showed significant increase in cell death although the proapoptotic gene PUMA was knocked out. By analyzing apoptosis via Annexin V-fluorescein isothiocyanate (FITC) assay with flow cytometry, both Bax− / − and PUMA− / − cells showed less apoptosis than WT, suggesting the existence of another type of cell death in PUMA− / − cells. Autophagy was then examined in three cell lines by counting the percentage of cells with punctate GFP-LC3. Although all three cell lines showed significantly increased autophagy activity after irradiation, that of PUMA− / − cells was much higher than the other two cell lines, which suggests that PUMA− / − cells may die through autophagy. This was then confirmed by the decreased cell death in PUMA− / − cells when autophagy was blocked by 3-MA. In addition, we also tested the responses of WT and Bid− / − MEFs to irradiation. Bid− / − MEFs but not WT died through autophagy after irradiation. These results imply the involvement of apoptosis-associated genes such as PUMA and Bid in autophagic cell death, which contributes to identifying the molecular mechanism by which autophagy drives cells to death.

description: The ARIANNA detector aims to detect neutrinos with energies above \SI{e16}{eV} by instrumenting 0.5 Teratons of ice with a surface array of a thousand independent radio detector stations in Antarctica. The Antarctic ice is transparent to the radio signals caused by the Askaryan effect which allows for a cost-effective instrumentation of large volumes. Several pilot stations are currently operating successfully at the Moore's Bay site (Ross Ice Shelf) and at the South Pole. As the ARIANNA detector stations are positioned at the surface, the more abundant cosmic-ray air showers are also measured and serve as a direct way to prove the capabilities of the detector. We will present measured cosmic rays and will show how the incoming direction, polarization and electric field of the cosmic-ray pulse can be reconstructed from single detector stations comprising 4 upward and 4 downward facing LPDA antennas.

description: To investigate the effect of atmospheric particulates on the chemistry and acidity of rainwater during the washout process in areas with highly acidic rainfall, rainwater and particulates (before, during and after rain) were sampled and analyzed from June 2008 to June 2009 in the Yangtze River Delta region, China. The volume-weighted mean pH of the rainwater was only 4.44 in Hangzhou, and the average concentrations of TSP (total-suspended particulates) and PM10 (particulates with aerodynamic equivalent diameters of less than 10 μm) during the study period were 191 μg/m3 and 155 μg/m3, respectively. The measured acid buffering capacities of PM10 and TSP were 1.31 ± 0.45 and 1.61 ± 0.84 ml/mg, on average, respectively, indicating that both had a certain acid buffering capacity. Rain appeared to have a pronounced scouring effect on particulates, except for F− and Cl− in PM10. Upon combining the correlation analysis between ions in particulates and rainwater with Enrichment Factor and Principal Component Analysis of the rainwater chemistry, the results suggested that the components of rainwater were mainly derived from washout processes acting on particulates from crustal dust and building industry sources (Ca2+), marine sources (Na+, K+ (in spring), Mg2+ and Cl−) and anthropogenic sources, especially secondary aerosols emitted from agricultural land, motor vehicles and industrial plants (NO3−, SO42-, and NH4+). The F− in rainwater was mainly contributed by gaseous pollutants, such as HF from cooling systems, coal burning and surrounding factories. Implications: The interaction between particulates and rain in areas with highly acidic rainfall include the following: rain appears to have a pronounced scouring effect on most components in the particulates; the components of the rainwater are mainly derived from washout processes acting on PM contributed by crustal dust, sea salt and secondary aerosol subcloud; and the acid buffering capacities of PM10 and TSP in Hangzhou are 1.31 ± 0.45 and 1.61 ± 0.84 ml/mg, respectively, and had a certain acid buffering capacity toward rainwater.

description: This research supports efforts to increase the uptake of Property Flood Resilience (PFR) measures in Scotland by: 1. exploring the reasons why people do not install PFR measures, using in-depth interviews with home and business owners who have been flooded; and 2. identifying what would help encourage owners to make resilient changes to their properties using lessons from Scotland, the UK and internationally, and across other disciplines, for example energy efficiency. Property owners interviewed for the study had minimal awareness of their flood risk prior to being flooded. Even when participants were aware of their property’s flood risk, from first-hand experience or information after they moved in, they struggled to accept it as an ongoing risk. The report uses a Theory of Change approach to illustrate the journey home and business owners need to go on to become fully resilient to flooding, and focuses on overcoming the lack of awareness and sense of responsibility as a priority. It identifies two priorities: Firstly, there is a clear need for general awareness raising pre-flood in areas at risk to shift attitudes towards greater risk awareness and risk acceptance. Secondly, this should be combined with a targeted communication campaign and signposting to help and inform at the crisis stage immediately after a flood. In addition a number of recommendations are made empower communities, and to create an environment around property owners that make uptake of PFR measures the easy choice. The need for information and support will increase as climate change increases the number of properties at risk of flooding in Scotland.

description: In today’s fast-paced and information-driven world, the role of a library transcends its conventional image. Libraries have evolved into dynamic centers of knowledge, culture, and connectivity, holding a pivotal place in modern life. As the digital age accelerates, the value of libraries becomes even more pronounced, serving as crucial spaces where individuals can engage with a treasure trove of resources, explore diverse perspectives, and foster personal and intellectual growth. Designing a library in the context of a memory bank is a visionary concept that aligns seamlessly with the evolving needs of contemporary society. Much like a repository of collective memory, a well-designed library becomes a sanctuary where the past, present, and future converge. Just as a memory bank preserves and safeguards invaluable recollections, a thoughtfully crafted library preserves the wealth of human knowledge, offering an immersive experience where generations can connect with the accumulated wisdom of ages gone by. In the following discourse, we will delve into the multifaceted significance of modern libraries and explore the concept of designing them as memory banks, unraveling how this visionary approach enriches our lives, nurtures intellectual exploration, and perpetuates the legacy of human achievement.

description: We calculate the linear polarization of gluons radiated off top quarks produced in e^+e^- annihilations. For typical top pair production energies at the Next-Linear-Collider (NLC) the degree of linear polarization remains close to its soft gluon value of 100% over almost the whole energy spectrum of the gluon. The massive quark results are compared with the corresponding results for the massless quark case.

description: The increasing volume of seismic data from long-term continuous monitoring motivates the development of algorithms based on convolutional neural network (CNN) for faster and more reliable phase detection and picking. However, many less studied regions lack a significant amount of labeled events needed for traditional CNN approaches. In this paper, we present a CNN-based Phase- Identification Classifier (CPIC) designed for phase detection and picking on small to medium sized training datasets. When trained on 30,146 labeled phases and applied to one-month of continuous recordings during the aftershock sequences of the 2008 MW 7.9 Wenchuan Earthquake in Sichuan, China, CPIC detects 97.5% of the manually picked phases in the standard catalog and predicts their arrival times with a five-times improvement over the ObsPy AR picker. In addition, unlike other CNN-based approaches that require millions of training samples, when the off-line training set size of CPIC is reduced to only a few thousand training samples the accuracy stays above 95%. The online implementation of CPIC takes less than 12 hours to pick arrivals in 31-day recordings on 14 stations. In addition to the catalog phases manually picked by analysts, CPIC finds more phases for existing events and new events missed in the catalog. Among those additional detections, some are confirmed by a matched filter method while others require further investigation. Finally, when tested on a small dataset from a different region (Oklahoma, US), CPIC achieves 97% accuracy after fine tuning only the fully connected layer of the model. This result suggests that the CPIC developed in this study can be used to identify and pick P/S arrivals in other regions with no or minimum labeled phases.

 = Tanacetum parthenium (L.) Sch. Bip.
 Notes. – Two gatherings have been located for this species: the specimen collected by Bruguière and Olivier in Iran in Ventenat’s herbarium and the cultivated specimen from Cels’s garden in G-DC [G00450767]. A second collection in Ventenat’s herbarium has no information on its origin. The Bruguière and Olivier collection is here designated as the lectotype. A second collection at G [G00341494] is considered as a probable isolectotype but could also represent a Cels’s garden collection and should then be considered as a duplicate of the material in G-DC.

description: We investigate the critical relaxational dynamics of the S=1/2 Heisenberg ferromagnet on a simple cubic lattice within the Handscomb prescription on which it is a diagrammatic series expansion of the partition function that is computed by means of a Monte Carlo procedure. Using a phenomenological renormalization group analysis of graph quantities related to the spin susceptibility and order parameter, we obtain precise estimates for the critical exponents relations $γ/ ν= 1.98\pm 0.01 $ and $β/ν= 0.512 \pm 0.002$ and for the Curie temperature $k_BT_c/J = 1.6778 \pm 0.0002$. The critical correlation time of both energy and susceptibility is also computed. We found that the number of Monte Carlo steps needed to generate uncorrelated diagram configurations scales with the system's volume. We estimate the efficiency of the Handscomb method comparing its ability in dealing with the critical slowing down with that of other quantum and classical Monte Carlo prescriptions.

description: Using angle-resolved photoemission spectroscopy (ARPES), we have observed the band structure, Fermi surface and their doping dependences in La2-xSrxCuO4. The results reveal that the Fermi surface undergoes a dramatic change: it is hole-like and centered at k=(pi,pi) in underdoped (x = 0.1) and optimally doped (x = 0.15) samples as in other cuprates while it is electron-like and centered at (0,0) in heavily overdoped (x = 0.3) ones. The peak in the ARPES spectra near (pi/2,pi/2) is broad and weak unlike in other cuprates. In the underdoped and optimally doped samples, a superconducting gap (Delta = 10 - 15 meV) is observed on the Fermi surface near (pi,0).

description: Mechanisms that control cell cycle dynamics during tissue regeneration require elucidation. Here we find in zebrafish that regeneration of the epicardium, the mesothelial covering of the heart, is mediated by two phenotypically distinct epicardial cell subpopulations. These include a front of large, multinucleate leader cells, trailed by follower cells that divide to produce small, mononucleate daughters. By live imaging of cell cycle dynamics, we show that leader cells form by spatiotemporally regulated endoreplication, caused primarily by cytokinesis failure. Leader cells display greater velocities and mechanical tension within the epicardial tissue sheet, and experimentally induced tension anisotropy stimulates ectopic endoreplication. Unbalancing epicardial cell cycle dynamics with chemical modulators indicated autonomous regenerative capacity in both leader and follower cells, with leaders displaying an enhanced capacity for surface coverage. Our findings provide evidence that mechanical tension can regulate cell cycle dynamics in regenerating tissue, stratifying the source cell features to improve repair.

 Lectotypus (designated here): [INDONESIA. Java]: Hort. Cels, Ventenat s.n. (G [G00341557]!).
 = Clerodendrum infortunatum L.
 Notes. – When validating the name Clerodendrum viscosum Ventenat specifically wrote that his species concept excluded what was named C. infortunatum L. in P-JU. Two collections exist in Ventenat’s herbarium. A cultivated specimen from Cels’s garden and a second with two leaves with a label “Dedit Juss., exclusis syn. et figuris Rhumphii et Burmanii” and two additional leaves with a blank label attached. The two leaves “Dedit Juss.” clearly represent what Ventenat called C. infortunatum and should not be considered as type material of his C. viscosum. No further material has been located at P-JU. In spite of any additional information regarding the two leaves present on the sheet we prefer to consider this specimen [G00341644] as original material whereas the cultivated plant from Cels’s garden is designated here as the lectotype.

description: Exposure to psychosocial stress is known to precipitate the emergence of stress related psychiatric disorders such as depression and anxiety. While mechanisms by which this occurs remain largely unclear, recent evidence points towards a causative role for inflammation. Neurotransmitters, such as norepinephrine (NE) are capable of regulating expression of proinflammatory cytokines and thus may contribute to the emergence of stress-related disorders. The locus coeruleus (LC) is the major source of norepinephrine (NE) to the brain and therefore the current study utilized N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4), an LC selective noradrenergic neurotoxin, to determine the discrete involvement of the LC-NE system in social defeat-induced inflammation in LC projection regions including the central amygdala (CeA), dorsal raphe (DR) and plasma. In the current study, rats were exposed to brief social defeat or control manipulations on 5 consecutive days. To determine whether a history of social defeat enhanced or “primed” the inflammatory response to a subsequent defeat exposure, all rats regardless of stress history were exposed to an acute social defeat challenge immediately prior to tissue collection. As anticipated, prior history of social defeat primed inflammatory responses in the plasma and CeA while neuroinflammation in the DR was markedly reduced. Notably, DSP-4 treatment suppressed stress-induced circulating inflammatory cytokines independent of prior stress history. In contrast, neuroinflammation in the CeA and DR were greatly augmented selectively in DSP-4 treated rats with a history of social defeat. Together these data highlight the dichotomous nature of NE in stress-induced inflammatory priming in the periphery and the brain and directly implicate the LC-NE system in these processes.
