In the first part, I compare the lay with Virgilian and Ovidian versions of Orpheus' myth. This comparison shows the anonymous author's deep knowledge of the ancient texts and complex way of rewriting them through stealing and hybridization. The lay was highly esteemed by Tolkien, who translated it and took inspiration from it while describing the Elven kingdom in The Hobbit and building the storyline of Beren and L{\´u}thien in The Silmarillion. Through this key tale, Orpheus/Orfeo's romance has a deep influence also on Aragorn and Arwen's story in The Lord of the Rings. The most important element that Tolkien takes from the Sir Orfeo figuration of the ancient story is undoubtedly the insertion of political theme: the link established between the recovery of the main character's beloved and the return to royal responsability. The second part of the paper is, thus, dedicated to the reception of Sir Orfeo and the classical myth in Tolkien. It shows how in his work the different steps of the tradition of Orpheus' story are co-present, creating an inextricable substrate of inspiration that nourishes his imagination.}, language = {en} } @article{Pezzini2022, author = {Pezzini, Giuseppe}, title = {(Classical) Narratives of Decline in Tolkien: Renewal, Accommodation, Focalisation}, series = {thersites 15}, volume = {2022}, journal = {thersites 15}, number = {15}, editor = {Amb{\"u}hl, Annemarie and Carl{\`a}-Uhink, Filippo and Rollinger, Christian and Walde, Christine}, issn = {2364-7612}, doi = {10.34679/thersites.vol15.213}, pages = {25 -- 51}, year = {2022}, abstract = {The paper investigates Tolkien's narratives of decline through the lens of their classical ancestry. Narratives of decline are widespread in ancient culture, in both philosophical and literary discourses. They normally posit a gradual degradation (moral and ontological) from an idealized Golden Age, which went hand-in-hand with increasing detachment of gods from mortal affairs. Narratives of decline are also at the core of Tolkien's mythology, constituting yet another underresearched aspect of classical influence on Tolkien. Such Classical narratives reverberate e.g. in Tolkien's division of Arda's history into ages, from an idealized First Age filled with Joy and Light to a Third Age, described as "Twilight Age (…) the first of the broken and changed world" (Letters 131). More generally, these narratives are related to Tolkien's notorious perception of history as a "long defeat" (Letters 195) and to that "heart-racking sense of the vanished past" which pervades Tolkien's works - the emotion which, in his words, moved him "supremely" and which he found "small difficulty in evoking" (Letters 91). The paper analyses the reception of narratives of decline in Tolkien's legendarium, pointing out similarities but also contrasts and differences, with the aim to discuss some key patterns of (classical) reception in Tolkien's theory and practice ('renewal', 'accommodation', 'focalization').}, language = {en} } @article{FranzSudoKhomenko2022, author = {Franz, Gerhard and Sudo, Masafumi and Khomenko, Vladimir}, title = {40Ar/39Ar dating of a hydrothermal pegmatitic buddingtonite-muscovite assemblage from Volyn, Ukraine}, series = {European journal of mineralogy : EJM : an international journal on mineralogy, petrology, geochemistry, and related sciences}, volume = {34}, journal = {European journal of mineralogy : EJM : an international journal on mineralogy, petrology, geochemistry, and related sciences}, number = {1}, publisher = {Copernicus}, address = {G{\"o}ttingen}, issn = {0935-1221}, doi = {10.5194/ejm-34-7-2022}, pages = {7 -- 18}, year = {2022}, abstract = {We determined Ar-40/Ar-39 ages of buddingtonite, occurring together with muscovite, with the laser-ablation method. This is the first attempt to date the NH4-feldspar buddingtonite, which is typical for sedimentary-diagenetic environments of sediments, rich in organic matter, or in hydrothermal environments, associated with volcanic geyser systems. The sample is a hydrothermal breccia, coming from the Paleoproterozoic pegmatite field of the Korosten Plutonic Complex, Volyn, Ukraine. A detailed characterization by optical methods, electron microprobe analyses, backscattered electron imaging, and IR analyses showed that the buddingtonite consists of euhedral-appearing platy crystals of tens of micrometers wide, 100 or more micrometers in length, which consist of fine-grained fibers of <= 1 mu m thickness. The crystals are sector and growth zoned in terms of K-NH4-H3O content. The content of K allows for an age determination with the Ar-40/Ar-39 method, as well as in the accompanying muscovite, intimately intergrown with the buddingtonite. The determinations on muscovite yielded an age of 1491 +/- 9 Ma, interpreted as the hydrothermal event forming the breccia. However, buddingtonite apparent ages yielded a range of 563 +/- 14 Ma down to 383 +/- 12 Ma, which are interpreted as reset ages due to Ar loss of the fibrous buddingtonite crystals during later heating. We conclude that buddingtonite is suited for Ar-40/Ar-39 age determinations as a supplementary method, together with other methods and minerals; however, it requires a detailed mineralogical characterization, and the ages will likely represent minimum ages.}, language = {en} } @article{HaueisStechKubick2022, author = {Haueis, Lisa and Stech, Marlitt and Kubick, Stefan}, title = {A Cell-free Expression Pipeline for the Generation and Functional Characterization of Nanobodies}, series = {Frontiers in Bioengineering and Biotechnology}, volume = {10}, journal = {Frontiers in Bioengineering and Biotechnology}, publisher = {Frontiers Media}, address = {Lausanne}, issn = {2296-4185}, doi = {10.3389/fbioe.2022.896763}, pages = {11}, year = {2022}, abstract = {Cell-free systems are well-established platforms for the rapid synthesis, screening, engineering and modification of all kinds of recombinant proteins ranging from membrane proteins to soluble proteins, enzymes and even toxins. Also within the antibody field the cell-free technology has gained considerable attention with respect to the clinical research pipeline including antibody discovery and production. Besides the classical full-length monoclonal antibodies (mAbs), so-called "nanobodies" (Nbs) have come into focus. A Nb is the smallest naturally-derived functional antibody fragment known and represents the variable domain (VHH, similar to 15 kDa) of a camelid heavy-chain-only antibody (HCAb). Based on their nanoscale and their special structure, Nbs display striking advantages concerning their production, but also their characteristics as binders, such as high stability, diversity, improved tissue penetration and reaching of cavity-like epitopes. The classical way to produce Nbs depends on the use of living cells as production host. Though cell-based production is well-established, it is still time-consuming, laborious and hardly amenable for high-throughput applications. Here, we present for the first time to our knowledge the synthesis of functional Nbs in a standardized mammalian cell-free system based on Chinese hamster ovary (CHO) cell lysates. Cell-free reactions were shown to be time-efficient and easy-to-handle allowing for the "on demand" synthesis of Nbs.

Cell-free ncAA incorporation is of particular interest due to the open nature of cell-free systems and their concurrent ease of manipulation. In this study, we report a straightforward workflow to inquire ncAA positions in regard to incorporation efficiency and protein functionality in a Chinese hamster ovary (CHO) cell-free system. As a model, the well-established orthogonal translation components Escherichia coli tyrosyl-tRNA synthetase (TyrRS) and tRNATyr(CUA) were used to site-specifically incorporate the ncAA p-azido-l-phenylalanine (AzF) in response to UAG codons. A total of seven ncAA sites within an anti-epidermal growth factor receptor (EGFR) single-chain variable fragment (scFv) N-terminally fused to the red fluorescent protein mRFP1 and C-terminally fused to the green fluorescent protein sfGFP were investigated for ncAA incorporation efficiency and impact on antigen binding. The characterized cell-free dual fluorescence reporter system allows screening for ncAA incorporation sites with high incorporation efficiency that maintain protein activity. It is parallelizable, scalable, and easy to operate.

This comparative analysis demonstrates that the best-performing phenomic prediction models show higher predictability than the best genomic prediction models for the considered traits and environments in the vast majority of comparisons within 3-way hybrid populations.

Their results provide a valuable resource to investigate clusters of functional and linked traits to better understand marine bacteria community assembly and dynamics. Microbial interactions shape the structure and function of microbial communities with profound consequences for biogeochemical cycles and ecosystem health. Yet, most interaction mechanisms are studied only in model systems and their prevalence is unknown. To systematically explore the functional and interaction potential of sequenced marine bacteria, we developed a trait-based approach, and applied it to 473 complete genomes (248 genera), representing a substantial fraction of marine microbial communities. We identified genome functional clusters (GFCs) which group bacterial taxa with common ecology and life history. Most GFCs revealed unique combinations of interaction traits, including the production of siderophores (10\% of genomes), phytohormones (3-8\%) and different B vitamins (57-70\%). Specific GFCs, comprising Alpha- and Gammaproteobacteria, displayed more interaction traits than expected by chance, and are thus predicted to preferentially interact synergistically and/or antagonistically with bacteria and phytoplankton. Linked trait clusters (LTCs) identify traits that may have evolved to act together (e.g., secretion systems, nitrogen metabolism regulation and B vitamin transporters), providing testable hypotheses for complex mechanisms of microbial interactions.

Structural models and prior parameter distributions used in MIPD approaches typically build on prior clinical trials that involve only a limited number of patients selected according to some exclusion/inclusion criteria. Compared to the prior clinical trial population, the patient population in clinical practice can be expected to also include altered behavior and/or increased interindividual variability, the extent of which, however, is typically unknown. Here, we address the question of how to adapt and refine models on the level of the model parameters to better reflect this real-world diversity. We propose an approach for continued learning across patients during MIPD using a sequential hierarchical Bayesian framework. The approach builds on two stages to separate the update of the individual patient parameters from updating the population parameters. Consequently, it enables continued learning across hospitals or study centers, because only summary patient data (on the level of model parameters) need to be shared, but no individual TDM data. We illustrate this continued learning approach with neutrophil-guided dosing of paclitaxel.

Hence, the current study aimed to investigate the associations between HGS and executive functioning in individuals with aMCI, naMCI and healthy controls. Older, right-handed adults with amnestic MCI (aMCI), non-amnestic MCI (naMCI), and healthy controls (HC) conducted a handgrip strength measurement via a handheld dynamometer. Executive functions were assessed with the Trail Making Test (TMT A\&B). Normalized handgrip strength (nHGS, normalized to Body Mass Index (BMI)) was calculated and its associations with executive functions (operationalized through z-scores of TMT B/A ratio) were investigated through partial correlation analyses (i.e., accounting for age, sex, and severity of depressive symptoms). A positive and low-to-moderate correlation between right nHGS (rp (22) = 0.364; p = 0.063) and left nHGS (rp (22) = 0.420; p = 0.037) and executive functioning in older adults with aMCI but not in naMCI or HC was observed.

In this process, parts of the positive and negative external flux converge toward the polarity inversion line, reconnect, and cancel each other. Flux of the same amount as the canceled flux transfers to a flux rope, increasing the free magnetic energy of the coronal field. With sustained flux cancellation and the associated progressive weakening of the magnetic tension of the overlying flux, we find that a flux reduction of approximate to 11\% initiates the torus instability of the flux rope, which leads to a full eruption.

Conventional quantitative indices, however, typically neglect the spatial extent or the duration, while both are important to understand potential impacts. In 2014, the weather extremity index (WEI) was suggested to quantify the extremeness of an event and to identify the spatial and temporal scale at which the event was most extreme. However, the WEI does not account for the fact that one event can be extreme at various spatial and temporal scales. To better understand and detect the compound nature of precipitation events, we suggest complementing the original WEI with a "cross-scale weather extremity index" (xWEI), which integrates extremeness over relevant scales instead of determining its maximum. Based on a set of 101 extreme precipitation events in Germany, we outline and demonstrate the computation of both WEI and xWEI. We find that the choice of the index can lead to considerable differences in the assessment of past events but that the most extreme events are ranked consistently, independently of the index. Even then, the xWEI can reveal cross-scale properties which would otherwise remain hidden. This also applies to the disastrous event from July 2021, which clearly outranks all other analyzed events with regard to both WEI and xWEI. While demonstrating the added value of xWEI, we also identify various methodological challenges along the required computational workflow: these include the parameter estimation for the extreme value distributions, the definition of maximum spatial extent and temporal duration, and the weighting of extremeness at different scales.

We find that emissions are largely dependent on a country's consumption patterns and their agricultural emission intensities relative to their trading partners'. The absolute differences between the production-based and trade-adjusted emissions accounting approaches are especially apparent for major agricultural exporters and importers and where large shares of emission-intensive items such as ruminant meat, milk products and rice are involved. In relative terms, some low-income and emerging and developing economies with consumption of high emission intensity food products show large differences between approaches. Similar trends are also found under various specifications that account for trade and re-exports differently.

In particular, insured individuals with a healthy lifestyle can receive a reduction of their contributions to be paid. However, this potential is hardly used in practice. Objective This study aims to identify which barrier factors impede the usage of wearables for assessing individual risk scores for health insurances, despite its technological feasibility, and to rank these barriers according to their relevance. Methods To reach these goals, we conduct a ranking-type Delphi study with the following three stages. First, we collected possible barrier factors from a panel of 16 experts and consolidated them to a list of 11 barrier categories. Second, the panel was asked to rank them regarding their relevance. Third, to enhance the panel consensus, the ranking was revealed to the experts, who were then asked to re-rank the barriers. Results The results suggest that regulation is the most important barrier. Other relevant barriers are false or inaccurate measurements and application errors caused by the users. Additionally, insurers could lack the required technological competence to use the wearable data appropriately. Conclusion A wider use of wearables and health apps could be achieved through regulatory modifications, especially regarding privacy issues. Even after assuring stricter regulations, users' privacy concerns could partly remain, if the data exchange between wearables manufacturers, health app providers, and health insurers does not become more transparent.}, language = {en} } @article{ZuhrDolmanHoetal.2022, author = {Zuhr, Alexandra M. and Dolman, Andrew M. and Ho, Sze Ling and Groeneveld, Jeroen and Loewemark, Ludvig and Grotheer, Hendrik and Su, Chih-Chieh and Laepple, Thomas}, title = {Age-heterogeneity in marine sediments revealed by three-dimensional high-resolution radiocarbon measurements}, series = {Frontiers in Earth Science}, volume = {10}, journal = {Frontiers in Earth Science}, publisher = {Frontiers Media}, address = {Lausanne}, issn = {2296-6463}, doi = {10.3389/feart.2022.871902}, pages = {15}, year = {2022}, abstract = {Marine sedimentary archives are routinely used to reconstruct past environmental changes. In many cases, bioturbation and sedimentary mixing affect the proxy time-series and the age-depth relationship. While idealized models of bioturbation exist, they usually assume homogeneous mixing, thus that a single sample is representative for the sediment layer it is sampled from. However, it is largely unknown to which extent this assumption holds for sediments used for paleoclimate reconstructions. To shed light on 1) the age-depth relationship and its full uncertainty, 2) the magnitude of mixing processes affecting the downcore proxy variations, and 3) the representativity of the discrete sample for the sediment layer, we designed and performed a case study on South China Sea sediment material which was collected using a box corer and which covers the last glacial cycle. Using the radiocarbon content of foraminiferal tests as a tracer of time, we characterize the spatial age-heterogeneity of sediments in a three-dimensional setup. In total, 118 radiocarbon measurements were performed on defined small- and large-volume bulk samples ( similar to 200 specimens each) to investigate the horizontal heterogeneity of the sediment. Additionally, replicated measurements on small numbers of specimens (10 x 5 specimens) were performed to assess the heterogeneity within a sample volume. Visual assessment of X-ray images and a quantitative assessment of the mixing strength show typical mixing from bioturbation corresponding to around 10 cm mixing depth. Notably, our 3D radiocarbon distribution reveals that the horizontal heterogeneity (up to 1,250 years), contributing to the age uncertainty, is several times larger than the typically assumed radiocarbon based age-model error (single errors up to 250 years). Furthermore, the assumption of a perfectly bioturbated layer with no mixing underneath is not met. Our analysis further demonstrates that the age-heterogeneity might be a function of sample size; smaller samples might contain single features from the incomplete mixing and are thus less representative than larger samples. We provide suggestions for future studies, optimal sampling strategies for quantitative paleoclimate reconstructions and realistic uncertainty in age models, as well as discuss possible implications for the interpretation of paleoclimate records.}, language = {en} } @article{MenzeMuellerMuelleretal.2022, author = {Menze, Inga and M{\"u}ller, Patrick and M{\"u}ller, Notger Germar and Schmicker, Marlen}, title = {Age-related cognitive effects of the COVID-19 pandemic restrictions and associated mental health changes in Germans}, series = {Scientific reports}, volume = {12}, journal = {Scientific reports}, number = {1}, publisher = {Nature portfolio}, address = {Berlin}, issn = {2045-2322}, doi = {10.1038/s41598-022-11283-9}, pages = {16}, year = {2022}, abstract = {Restrictive means to reduce the spread of the COVID-19 pandemic have not only imposed broad challenges on mental health but might also affect cognitive health.

However, population decline was reported over the last decades and is still ongoing. While agricultural intensification is a major driver of the rapid loss of pollinating species, transition zones between arable fields and forest or grassland patches, i.e., agricultural buffer zones, are frequently mentioned as suitable mitigation measures to support wild bee populations and other pollinator species. Despite the reported general positive effect, it remains unclear which amount of buffer zones is needed to ensure a sustainable and permanent impact for enhancing bee diversity and abundance. To address this question at a pollinator community level, we implemented a process-based, spatially explicit simulation model of functional bee diversity dynamics in an agricultural landscape. More specifically, we introduced a variable amount of agricultural buffer zones (ABZs) at the transition of arable to grassland, or arable to forest patches to analyze the impact on bee functional diversity and functional richness. We focused our study on solitary bees in a typical agricultural area in the Northeast of Germany. Our results showed positive effects with at least 25\% of virtually implemented agricultural buffer zones. However, higher amounts of ABZs of at least 75\% should be considered to ensure a sufficient increase in Shannon diversity and decrease in quasi-extinction risks. These high amounts of ABZs represent effective conservation measures to safeguard the stability of pollination services provided by solitary bee species. As the model structure can be easily adapted to other mobile species in agricultural landscapes, our community approach offers the chance to compare the effectiveness of conservation measures also for other pollinator communities in future.}, language = {en} } @article{Ette2022, author = {Ette, Ottmar}, title = {Alexander von Humboldt im Archiv}, series = {HiN : Alexander von Humboldt im Netz ; International Review for Humboldtian Studies}, volume = {XXIII}, journal = {HiN : Alexander von Humboldt im Netz ; International Review for Humboldtian Studies}, number = {45}, editor = {Ette, Ottmar and Knobloch, Eberhard}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {2568-3543}, doi = {10.25932/publishup-59232}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-592326}, pages = {13 -- 28}, year = {2022}, abstract = {Der Aufsatz erschließt die Anf{\"a}nge, Ergebnisse und Erfolge der editionsphilologischen Arbeit im laufenden Projekt des BBAW-Langzeitvorhabens „Alexander von Humboldt auf Reisen - Wissenschaft aus der Bewegung" und gibt einen {\"U}berblick {\"u}ber die Zuk{\"u}nfte philologischen Arbeitens mit den Methoden der Digital Humanities.

Intuitive eating (IE), i.e., eating in accordance with internal hunger and satiety cues, may protect from overeating. IE, however, requires accurate perception and processing of one's own bodily signals, also referred to as interoceptive sensitivity. Training interoceptive sensitivity might therefore be an effective method to promote IE and prevent overeating. As most studies on eating behavior are conducted in younger adults and close social relationships influence health-related behavior, this study focuses on middle-aged and older couples. Methods The present pilot randomized intervention study aims at investigating the feasibility and effectiveness of a 21-day mindfulness-based training program designed to increase interoceptive sensitivity. A total of N = 60 couples participating in the NutriAct Family Study, aged 50-80 years, will be recruited. This randomized-controlled intervention study comprises three measurement points (pre-intervention, post-intervention, 4-week follow-up) and a 21-day training that consists of daily mindfulness-based guided audio exercises (e.g., body scan). A three-arm intervention study design is applied to compare two intervention groups (training together as a couple vs. training alone) with a control group (no training).

In recent decades, the high demand for water has increased the exploitation of groundwater, thus lowering the groundwater level and leading to risks of degradation, depletion, and land subsidence, as well as salinity intrusion in the groundwater of the whole Mekong Delta region. By using a finite element groundwater model with boundary expansion to the sea, we updated the latest data on hydrogeological profiles, groundwater levels, and exploitation. The basic model setup covers seven aquifers and seven aquitards. It is determined that the inflow along the coastline to the mainland is 39\% of the total inflow. The exploitation of the study area in 2019 was 567,364 m(3)/day. The most exploited aquifers are the upper-middle Pleistocene (qp(2-3)) and the middle Pliocene (n(2)(2)), accounting for 63.7\% and 24.6\%, respectively; the least exploited aquifers are the upper Pleistocene and the upper Miocene, accounting for 0.35\% and 0.02\%, respectively. In the deeper aquifers, qp(2-3) and n(2)(2), the change in storage is negative due to the high exploitation rate, leading to a decline in the reserves of these aquifers. These groundwater model results are the calculations of groundwater reserves from the coast to the mainland in the entire system of aquifers in the CMP. This makes groundwater decision managers, stakeholders, and others more efficient in sustainable water resources planning in the CMP and Mekong Delta (MKD).}, language = {en} } @article{ArkesAbereggArpin2022, author = {Arkes, Hal R. and Aberegg, Scott K. and Arpin, Kevin A.}, title = {Analysis of physicians' probability estimates of a medical outcome based on a sequence of events}, series = {JAMA network open / American Medical Association}, volume = {5}, journal = {JAMA network open / American Medical Association}, number = {6}, publisher = {American Veterinary Medical Association}, address = {Chicago}, issn = {2574-3805}, doi = {10.1001/jamanetworkopen.2022.18804}, pages = {10}, year = {2022}, abstract = {IMPORTANCE The probability of a conjunction of 2 independent events is the product of the probabilities of the 2 components and therefore cannot exceed the probability of either component; violation of this basic law is called the conjunction fallacy. A common medical decision-making scenario involves estimating the probability of a final outcome resulting from a sequence of independent events; however, little is known about physicians' ability to accurately estimate the overall probability of success in these situations. OBJECTIVE To ascertain whether physicians are able to correctly estimate the overall probability of a medical outcome resulting from 2 independent events. DESIGN, SETTING, AND PARTICIPANTS This survey study consisted of 3 separate substudies, in which 215 physicians were asked via internet-based survey to estimate the probability of success of each of 2 components of a diagnostic or prognostic sequence as well as the overall probability of success of the 2-step sequence. Substudy 1 was performed from April 2 to 4, 2021, substudy 2 from November 2 toll, 2021, and substudy 3 from May 13 to 19, 2021. All physicians were board certified or board eligible in the primary specialty germane to the substudy (ie, obstetrics and gynecology for substudies land 3 and pulmonology for substudy 2), were recruited from a commercial survey service, and volunteered to participate in the study. EXPOSURES Case scenarios presented in an online survey. MAIN OUTCOMES AND MEASURES Respondents were asked to provide their demographic information in addition to 3 probability estimates. The first substudy included a scenario describing a brow presentation discovered during labor; the 2 conjuncts were the probabilities that the brow presentation would resolve and that the delivery would be vaginal. The second substudy involved a diagnostic evaluation of an incidentally discovered pulmonary nodule; the 2 conjuncts were the probabilities that the patient had a malignant condition and that a technically successful transthoracic needle biopsy would reveal a malignant condition. The third substudy included a modification of the first substudy in an attempt to debias the conjunction fallacy prevalent in the first substudy. Respondents' own probability estimates of the individual events were used to calculate the mathematically correct conjunctive probability. RESULTS Among 215 respondents, the mean (SD) age was 54.0 (9.5) years; 142 respondents (66.0\%) were male. Data on race and ethnicity were not collected. A total of 168 physicians (78.1\%) estimated the probability of the 2-step sequence to be greater than the probability of at least 1 of the 2 component events. Compared with the product of their 2 estimated components, respondents overestimated the combined probability by 12.8\% (95\% CI, 9.6\%-16.1\%; P < .001) in substudy 1, 19.8\% (95\% Cl, 16.6\%-23.0\%; P < .001) in substudy 2, and 18.0\% (95\% CI, 13.4\%-22.5\%; P < .001) in substudy 3, results that were mathematically incoherent (ie, formally illogical and mathematically incorrect). CONCLUSIONS AND RELEVANCE In this survey study of 215 physicians, respondents consistently overestimated the combined probability of 2 events compared with the probability calculated from their own estimates of the individual events. This biased estimation, consistent with the conjunction fallacy, may have substantial implications for diagnostic and prognostic decision-making.}, language = {en} } @article{DieterichLindemannMoskoppetal.2022, author = {Dieterich, Peter and Lindemann, Otto and Moskopp, Mats Leif and Tauzin, Sebastien and Huttenlocher, Anna and Klages, Rainer and Chechkin, Aleksei V. and Schwab, Albrecht}, title = {Anomalous diffusion and asymmetric tempering memory in neutrophil chemotaxis}, series = {PLoS Computational Biology : a new community journal}, volume = {18}, journal = {PLoS Computational Biology : a new community journal}, number = {5}, publisher = {PLoS}, address = {San Fransisco}, issn = {1553-734X}, doi = {10.1371/journal.pcbi.1010089}, pages = {26}, year = {2022}, abstract = {Neutrophil granulocytes are essential for the first host defense. After leaving the blood circulation they migrate efficiently towards sites of inflammation. They are guided by chemoattractants released from cells within the inflammatory foci. On a cellular level, directional migration is a consequence of cellular front-rear asymmetry which is induced by the concentration gradient of the chemoattractants. The generation and maintenance of this asymmetry, however, is not yet fully understood. Here we analyzed the paths of chemotacting neutrophils with different stochastic models to gain further insight into the underlying mechanisms. Wildtype chemotacting neutrophils show an anomalous superdiffusive behavior. CXCR2 blockade and TRPC6-knockout cause the tempering of temporal correlations and a reduction of chemotaxis. Importantly, such tempering is found both in vitro and in vivo. These findings indicate that the maintenance of anomalous dynamics is crucial for chemotactic behavior and the search efficiency of neutrophils. The motility of neutrophils and their ability to sense and to react to chemoattractants in their environment are of central importance for the innate immunity. Neutrophils are guided towards sites of inflammation following the activation of G-protein coupled chemoattractant receptors such as CXCR2 whose signaling strongly depends on the activity of Ca2+ permeable TRPC6 channels. It is the aim of this study to analyze data sets obtained in vitro (murine neutrophils) and in vivo (zebrafish neutrophils) with a stochastic mathematical model to gain deeper insight into the underlying mechanisms. The model is based on the analysis of trajectories of individual neutrophils. Bayesian data analysis, including the covariances of positions for fractional Brownian motion as well as for exponentially and power-law tempered model variants, allows the estimation of parameters and model selection. Our model-based analysis reveals that wildtype neutrophils show pure superdiffusive fractional Brownian motion. This so-called anomalous dynamics is characterized by temporal long-range correlations for the movement into the direction of the chemotactic CXCL1 gradient. Pure superdiffusion is absent vertically to this gradient. This points to an asymmetric 'memory' of the migratory machinery, which is found both in vitro and in vivo. CXCR2 blockade and TRPC6-knockout cause tempering of temporal correlations in the chemotactic gradient. This can be interpreted as a progressive loss of memory, which leads to a marked reduction of chemotaxis and search efficiency of neutrophils. In summary, our findings indicate that spatially differential regulation of anomalous dynamics appears to play a central role in guiding efficient chemotactic behavior.}, language = {en} } @article{IlicicWoodhouseKarstenetal.2022, author = {Ilicic, Doris and Woodhouse, Jason Nicholas and Karsten, Ulf and Zimmermann, Jonas and Wichard, Thomas and Quartino, Maria Liliana and Campana, Gabriela Laura and Livenets, Alexandra and Van den Wyngaert, Silke and Grossart, Hans-Peter}, title = {Antarctic Glacial Meltwater Impacts the Diversity of Fungal Parasites Associated With Benthic Diatoms in Shallow Coastal Zones}, series = {Frontiers in microbiology}, journal = {Frontiers in microbiology}, number = {13}, publisher = {Frontiers Media}, address = {Lausanne}, issn = {1664-302X}, doi = {10.3389/fmicb.2022.805694}, pages = {12}, year = {2022}, abstract = {Aquatic ecosystems are frequently overlooked as fungal habitats, although there is increasing evidence that their diversity and ecological importance are greater than previously considered. Aquatic fungi are critical and abundant components of nutrient cycling and food web dynamics, e.g., exerting top-down control on phytoplankton communities and forming symbioses with many marine microorganisms. However, their relevance for microphytobenthic communities is almost unexplored. In the light of global warming, polar regions face extreme changes in abiotic factors with a severe impact on biodiversity and ecosystem functioning. Therefore, this study aimed to describe, for the first time, fungal diversity in Antarctic benthic habitats along the salinity gradient and to determine the co-occurrence of fungal parasites with their algal hosts, which were dominated by benthic diatoms. Our results reveal that Ascomycota and Chytridiomycota are the most abundant fungal taxa in these habitats. We show that also in Antarctic waters, salinity has a major impact on shaping not just fungal but rather the whole eukaryotic community composition, with a diversity of aquatic fungi increasing as salinity decreases. Moreover, we determined correlations between putative fungal parasites and potential benthic diatom hosts, highlighting the need for further systematic analysis of fungal diversity along with studies on taxonomy and ecological roles of Chytridiomycota.}, language = {en} } @incollection{Balderjahn2022, author = {Balderjahn, Ingo}, title = {Anti-Consumption und Nachhaltigkeit}, series = {Marke, Nachhaltigkeit und Verbraucherpolitik : Die Gew{\"a}hrleistungsmarke im Spannungsfeld zwischen Unternehmen, Konsumenten und Regulierung}, booktitle = {Marke, Nachhaltigkeit und Verbraucherpolitik : Die Gew{\"a}hrleistungsmarke im Spannungsfeld zwischen Unternehmen, Konsumenten und Regulierung}, editor = {Boltz, Dirk-Mario and Bruhn, Manfred and Gr{\"o}ppel-Klein, Andrea and Hellmann, Kai-Uwe}, publisher = {Nomos}, address = {Baden-Baden}, isbn = {978-3-7489-1271-2}, doi = {10.5771/9783748912712-29}, pages = {29 -- 40}, year = {2022}, language = {de} } @article{HerrmannBodenMaureretal.2022, author = {Herrmann, Matthias L. and Boden, Cindy and Maurer, Christoph and Kentischer, Felix and Mennig, Eva and Wagner, S{\"o}ren and Conzelmann, Lars O. and F{\"o}rstner, Bernd R. and Rapp, Michael A. and von Arnim, Christine A.

Because of its great impact on patients' safety and quality of life, identification of modifiable risk factors could be useful. Although preoperative medication intake is assumed to be an important modifiable risk factor, the impact of anticholinergic drugs on the occurrence of POD seems underestimated in elective surgery. The aim of this study was to investigate the association between preoperative anticholinergic burden and POD. We hypothesized that a high preoperative anticholinergic burden is an independent, potentially modifiable predisposing and precipitating factor of POD in older people. MethodsBetween November 2017 and April 2019, 1,470 patients of 70 years and older undergoing elective orthopedic, general, cardiac, or vascular surgery were recruited in the randomized, prospective, multicenter PAWEL trial. Anticholinergic burden of a sub-cohort of 899 patients, who did not receive a multimodal intervention for preventing POD, was assessed by two different tools at hospital admission: The established Anticholinergic Risk Scale (ARS) and the recently developed Anticholinergic Burden Score (ABS). POD was detected by confusion assessment method (CAM) and a validated post discharge medical record review. Logistic regression analyses were performed to evaluate the association between anticholinergic burden and POD. ResultsPOD was observed in 210 of 899 patients (23.4\%). Both ARS and ABS were independently associated with POD. The association persisted after adjustment for relevant confounding factors such as age, sex, comorbidities, preoperative cognitive and physical status, number of prescribed drugs, surgery time, type of surgery and anesthesia, usage of heart-lung-machine, and treatment in intensive care unit. If a patient was taking one of the 56 drugs listed in the ABS, risk for POD was 2.7-fold higher (OR = 2.74, 95\% CI = 1.55-4.94) and 1.5-fold higher per additional point on the ARS (OR = 1.54, 95\% CI = 1.15-2.02). ConclusionPreoperative anticholinergic drug exposure measured by ARS or ABS was independently associated with POD in older patients undergoing elective surgery. Therefore, identification, discontinuation or substitution of anticholinergic medication prior to surgery may be a promising approach to reduce the risk of POD in older patients.}, language = {en} } @article{Huelsenberg2022, author = {H{\"u}lsenberg, Dagmar}, title = {Anwendung naturwissenschaftlicher und kameralistischer Erkenntnisse auf die Verarbeitung von Rohstoffen durch den jungen Alexander von Humboldt}, series = {HiN : Alexander von Humboldt im Netz ; International Review for Humboldtian Studies}, volume = {XXIII}, journal = {HiN : Alexander von Humboldt im Netz ; International Review for Humboldtian Studies}, number = {44}, editor = {Ette, Ottmar and Knobloch, Eberhard}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1617-5239}, doi = {10.25932/publishup-58936}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-589363}, pages = {33 -- 57}, year = {2022}, abstract = {Alexander von Humboldt geh{\"o}rt zu den ersten Fachleuten, die f{\"u}r die sichere Beherrschung technischer und {\"o}konomischer Prozesse gleichzeitig naturwissenschaftliche und kameralistische Kenntnisse anwendeten und dabei weiterentwickelten.

The basin offers an excellent opportunity to investigate environmental signal propagation into the sedimentary record because comprehensive stratigraphic and seismic datasets can be combined with present research results. The bulk-rock clay-sized fraction epsilon Nd values of well-cutting samples from one well on the northern basin slope remained stable at similar to-9.7 from 27 to 19 Ma but increased after 19 Ma to similar to-9.1. In contrast, apatite single-grain distributions, which were extracted from 22 drill-core samples, changed significantly around 23.3 Ma from apatites dominantly from low-grade (
