With the help of a test developed for this purpose from a conceptual model, we examine whether this pedagogical content knowledge can be promoted in its different facets—especially knowledge about modelling tasks and about interventions—by suitable university seminars. For this purpose, the test was administered to three groups in a seminar for the teaching of mathematical modelling: (1) to those respondents who created their own modelling tasks for use with students, (2) to those trained to intervene in mathematical modelling processes, and (3) participating students who are not required to address mathematical modelling. The findings of the study—based on variance analysis—indicate that certain facets (knowledge of modelling tasks, modelling processes, and interventions) have increased significantly in both experimental groups but to varying degrees. By contrast, pre-service teachers in the control group demonstrated no significant change to their level of pedagogical content knowledge.}, language = {en} } @misc{KosmalaGruschwitzVeldhoenetal.2022, author = {Kosmala, Aleksander and Gruschwitz, Philipp and Veldhoen, Simon and Weng, Andreas Max and Krauss, Bernhard and Bley, Thorsten Alexander and Petritsch, Bernhard}, title = {Correction to: Dual-energy CT angiography in suspected pulmonary embolism: infuence of injection protocols on image quality and perfused blood volume}, series = {The International Journal of Cardiovascular Imaging}, volume = {38}, journal = {The International Journal of Cardiovascular Imaging}, number = {3}, doi = {10.1007/s10554-021-02439-1}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-350830}, pages = {707}, year = {2022}, abstract = {No abstract available.}, language = {en} } @article{MerzenichBaakenSchmidtetal.2022, author = {Merzenich, Hiltrud and Baaken, Dan and Schmidt, Marcus and Bekes, Inga and Schwentner, Lukas and Janni, Wolfgang and Woeckel, Achim and Bartkowiak, Detlef and Wiegel, Thomas and Blettner, Maria and Wollschl{\"a}ger, Daniel and Schmidberger, Heinz}, title = {Cardiac late effects after modern 3D-conformal radiotherapy in breast cancer patients: a retrospective cohort study in Germany (ESCaRa)}, series = {Breast Cancer Research and Treatment}, volume = {191}, journal = {Breast Cancer Research and Treatment}, number = {1}, issn = {0167-6806}, doi = {10.1007/s10549-021-06412-3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-308606}, pages = {147-157}, year = {2022}, abstract = {Purpose Radiotherapy (RT) was identified as a risk factor for long-term cardiac effects in breast cancer patients treated until the 1990s. However, modern techniques reduce radiation exposure of the heart, but some exposure remains unavoidable. In a retrospective cohort study, we investigated cardiac mortality and morbidity of breast cancer survivors treated with recent RT in Germany. Methods A total of 11,982 breast cancer patients treated between 1998 and 2008 were included. A mortality follow-up was conducted until 06/2018. In order to assess cardiac morbidity occurring after breast cancer treatment, a questionnaire was sent out in 2014 and 2019. The effect of breast cancer laterality on cardiac mortality and morbidity was investigated as a proxy for radiation exposure. We used Cox Proportional Hazards regression analysis, taking potential confounders into account. Results After a median follow-up time of 11.1 years, there was no significant association of tumor laterality with cardiac mortality in irradiated patients (hazard ratio (HR) for left-sided versus right-sided tumor 1.09; 95\% confidence interval (CI) 0.85-1.41). Furthermore, tumor laterality was not identified as a significant risk factor for cardiac morbidity (HR = 1.05; 95\%CI 0.88-1.25). Conclusions Even though RT for left-sided breast cancer on average incurs higher radiation dose to the heart than RT for right-sided tumors, we found no evidence that laterality is a strong risk factor for cardiac disease after contemporary RT. However, larger sample sizes, longer follow-up, detailed information on individual risk factors and heart dose are needed to assess clinically manifest late effects of current cancer therapy.}, language = {en} } @article{DippellEspositoWaldmann2022, author = {Dippell, Marvin and Esposito, Chiara and Waldmann, Stefan}, title = {Deformation and Hochschild cohomology of coisotropic algebras}, series = {Annali di Matematica Pura ed Applicata}, volume = {201}, journal = {Annali di Matematica Pura ed Applicata}, number = {3}, doi = {10.1007/s10231-021-01158-7}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-329069}, pages = {1295-1323}, year = {2022}, abstract = {Coisotropic algebras consist of triples of algebras for which a reduction can be defined and unify in a very algebraic fashion coisotropic reduction in several settings.

While most studies have focused on vertebrates, a growing body of research demonstrates that also insects such as honeybees possess basic quantitative abilities that might aid them in finding profitable flower patches. However, it remains unclear if for insects, quantity is a salient feature relative to other stimulus dimensions, or if it is only used as a "last resort" strategy in case other stimulus dimensions are inconclusive. Here, we tested the stingless bee Trigona fuscipennis, a species representative of a vastly understudied group of tropical pollinators, in a quantity discrimination task. In four experiments, we trained wild, free-flying bees on stimuli that depicted either one or four elements. Subsequently, bees were confronted with a choice between stimuli that matched the training stimulus either in terms of quantity or another stimulus dimension. We found that bees were able to discriminate between the two quantities, but performance differed depending on which quantity was rewarded. Furthermore, quantity was more salient than was shape. However, quantity did not measurably influence the bees' decisions when contrasted with color or surface area. Our results demonstrate that just as honeybees, small-brained stingless bees also possess basic quantitative abilities. Moreover, invertebrate pollinators seem to utilize quantity not only as "last resort" but as a salient stimulus dimension. Our study contributes to the growing body of knowledge on quantitative cognition in invertebrate species and adds to our understanding of the evolution of numerical cognition.}, language = {en} } @article{OhlmannBoemickeBehnischetal.2022, author = {Ohlmann, Brigitte and B{\"o}micke, Wolfgang and Behnisch, Rouven and Rammelsberg, Peter and Schmitter, Marc}, title = {Variability of sleep bruxism — findings from consecutive nights of monitoring}, series = {Clinical Oral Investigations}, volume = {26}, journal = {Clinical Oral Investigations}, number = {4}, issn = {1436-3771}, doi = {10.1007/s00784-021-04314-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-307645}, pages = {3459-3466}, year = {2022}, abstract = {Objectives To determine sleep bruxism (SB) behavior during five consecutive nights and to identify correlations between SB episodes per hour (SB index) and sleep-time masseter-muscle activity (sMMA). Material and methods Thirty-one participants were included in the study. Of these, 10 were classified as sleep bruxers (group SB-1) and nine as non-sleep bruxers (group non-SB). The bruxism status of these 19 patients was identified by means of questionnaires, an assessment of clinical symptoms, and electromyographic/electrocardiographic data (Bruxoff® device). The remaining 12 participants were also identified as bruxers, but based exclusively on data from the Bruxoff device (group SB-2). Data analysis included descriptive statistics and Spearman's correlation to assess the relationship between the SB index and sMMA. Results Participants in group SB-1 showed an overall mean SB index of 3.1 ± 1.6 and a mean total sMMA per night of 62.9 ± 38.3. Participants in group SB-2 had an overall mean SB index of 2.7 ± 1.5 and a mean total sMMA of 56.0 ± 29.3. In the non-SB group, participants showed an overall mean SB index of 0.8 ± 0.5 and a mean total sMMA of 56.8 ± 30.3. Spearman's correlation yielded values of - 0.27 to 0.71 for the correlation between sMMA and SB index. Conclusions The data revealed variable SB activity and the absence of a reliable correlation between sMMA and the SB index.

However, it remains unknown whether natural killer (NK) cell development and functions are altered in Rag1\(^{-/-}\) mice as well. This connection has been rarely discussed in previous studies but might have important implications for data interpretation. In contrast, the NOD-Rag1\(^{null}\)IL2rg\(^{null}\) (NRG) mouse model is devoid of NK cells and might therefore eliminate this potential shortcoming. Here, we compare immune-cell frequencies as well as phenotype and effector functions of NK cells in Rag1\(^{-/-}\) and wildtype (WT) mice using flow cytometry and functional in vitro assays. Further, we investigate the effect of Rag1\(^{-/-}\) NK cells in the transient middle cerebral artery occlusion (tMCAO) model using antibody-mediated depletion of NK cells and adoptive transfer to NRG mice in vivo. NK cells in Rag1\(^{-/-}\) were comparable in number and function to those in WT mice. Rag1\(^{-/-}\) mice treated with an anti-NK1.1 antibody developed significantly smaller infarctions and improved behavioral scores. Correspondingly, NRG mice supplemented with NK cells were more susceptible to tMCAO, developing infarctions and neurological deficits similar to Rag1-/- controls. Our results indicate that NK cells from Rag1-/- mice are fully functional and should therefore be considered in the interpretation of immune-cell transfer models in experimental stroke.

We aimed to characterize the plasma metabolome of PPGL patients before and after surgery, using an untargeted approach, and to broaden the scope of the investigated metabolic impact of these tumors. Design A cohort of 36 PPGL patients was investigated. Blood plasma samples were collected before and after surgical tumor removal, in association with clinical and tumor characteristics. Methods Plasma samples were analyzed using untargeted nuclear magnetic resonance (NMR) spectroscopy metabolomics. The data were evaluated using a combination of uni- and multi-variate statistical methods. Results Before surgery, patients with a nonadrenergic tumor could be distinguished from those with an adrenergic tumor based on their metabolic profiles. Tyrosine levels were significantly higher in patients with high compared to those with low BMI. Comparing subgroups of pre-operative samples with their post-operative counterparts, we found a metabolic signature that included ketone bodies, glucose, organic acids, methanol, dimethyl sulfone and amino acids. Three signals with unclear identities were found to be affected. Conclusions Our study suggests that the pathways of glucose and ketone body homeostasis are affected in PPGL patients.

Results Median time of follow-up was 18 months in IIH and 69 months in PH. The median time from initiation of immunotherapy to IIH diagnosis was 3 months. IIH affected males more frequently than PH (p < 0.001) and led to more impaired pituitary axes in males (p < 0.001).

A long appreciated, yet elusively defined relationship exists between the lytic-latent switch and viral non-coding RNAs 3,4. Here, we identify miRNA-mediated inhibition of miRNA processing as a thus far unknown cellular mechanism that human herpesvirus 6A (HHV-6A) exploits to disrupt mitochondrial architecture, evade intrinsic host defense and drive the lytic-latent switch. We demonstrate that virus-encoded miR-aU14 selectively inhibits the processing of multiple miR-30 family members by direct interaction with the respective pri-miRNA hairpin loops. Subsequent loss of miR-30 and activation of the miR-30/p53/Drp1 axis triggers a profound disruption of mitochondrial architecture. This impairs induction of type I interferons and is necessary for both productive infection and virus reactivation. Ectopic expression of miR-aU14 triggered virus reactivation from latency, identifying viral miR-aU14 as a readily drugable master regulator of the herpesvirus lytic-latent switch. Our results show that miRNA-mediated inhibition of miRNA processing represents a generalized cellular mechanism that can be exploited to selectively target individual members of miRNA families.

Autoimmunity might play a role in PD pathogenesis. Here we analyzed whether anti-brain autoantibodies differentially recognize different human brain areas and identified autoantigens that correlate with the above-described dissemination of PD pathology in the brain. Brain tissue was obtained from deceased individuals with no history of neurological or psychiatric disease and no neuropathological abnormalities. Tissue homogenates from different brain regions (DM, SN, MC, HC, FC) were subjected to SDS-PAGE and Western blot. Blots were incubated with plasma samples from 30 PD patients and 30 control subjects and stained with anti-IgG antibodies to detect anti-brain autoantibodies. Signals were quantified. Prominent autoantigens were identified by 2D-gel-coupled mass spectrometry sequencing. Anti-brain autoantibodies are frequent and occur both in healthy controls and individuals with PD. Glial fibrillary acidic protein (GFAP) was identified as a prominent autoantigen recognized in all plasma samples. GFAP immunoreactivity was highest in DM areas and lowest in FC areas with no significant differences in anti-GFAP autoantibody titers between healthy controls and individuals with PD.

We hypothesize that GFAP autoantibodies are physiological but might be involved as a cofactor in PD pathogenesis secondary to a leakage of the blood-brain barrier.}, language = {en} } @article{HartrampfWeinzierlBucketal.2022, author = {Hartrampf, Philipp E. and Weinzierl, Franz-Xaver and Buck, Andreas K. and Rowe, Steven P. and Higuchi, Takahiro and Seitz, Anna Katharina and K{\"u}bler, Hubert and Schirbel, Andreas and Essler, Markus and Bundschuh, Ralph A. and Werner, Rudolf A.}, title = {Matched-pair analysis of [\(^{177}\)Lu]Lu-PSMA I\&T and [\(^{177}\)Lu]Lu-PSMA-617 in patients with metastatic castration-resistant prostate cancer}, series = {European Journal of Nuclear Medicine and Molecular Imaging}, volume = {49}, journal = {European Journal of Nuclear Medicine and Molecular Imaging}, number = {9}, doi = {10.1007/s00259-022-05744-6}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-324581}, pages = {3269-3276}, year = {2022}, abstract = {Background Labelled with lutetium-177, the urea-based small molecules PSMA I\&T and PSMA-617 are the two agents most frequently used for radioligand therapy (RLT) in patients with advanced metastatic castration-resistant and prostate-specific membrane antigen (PSMA) expressing prostate cancer (mCRPC). In this matched-pair analysis, we aimed to compare the toxicity and efficacy of both agents for PSMA-directed RLT. Materials and methods A total of 110 mCRPC patients from two centres were accrued, 55 individuals treated with [\(^{177}\)Lu]Lu-PSMA I\&T, and a matched cohort of 55 patients treated with [\(^{177}\)Lu]Lu-PSMA-617. Matching criteria included age at the first cycle, Gleason score, prostate-specific antigen (PSA) values, and previous taxane-based chemotherapy. Using common terminology criteria for adverse events (CTCAE v. 5.0), toxicity profiles were investigated (including bone marrow and renal toxicity). Overall survival (OS) between both groups was compared. Results Toxicity assessment revealed grade III anaemia in a single patient (1.8\%) for [\(^{177}\)Lu]Lu-PSMA I\&T and five (9.1\%) for [\(^{177}\)Lu]Lu-PSMA-617. In addition, one (1.9\%) grade III thrombopenia for [\(^{177}\)Lu]Lu-PSMA-617 was recorded. Apart from that, no other grade III/IV toxicities were present. A median OS of 12 months for patients treated with [\(^{177}\)Lu]Lu-PSMA I\&T did not differ significantly when compared to patients treated with [\(^{177}\)Lu]Lu-PSMA-617 (median OS, 13 months; P = 0.89). Conclusion In this matched-pair analysis of patients receiving one of the two agents most frequently applied for PSMA RLT, the rate of clinically relevant toxicities was low for both compounds. In addition, no relevant differences for OS were observed.}, language = {en} } @article{KuonBlasiUnsoeldetal.2022, author = {Kuon, Jonas and Blasi, Miriam and Uns{\"o}ld, Laura and Vogt, Jeannette and Mehnert, Anja and Alt-Epping, Bernd and Oorschot, Birgitt van and Sistermanns, Jochen and Ahlborn, Miriam and Ritterbusch, Ulrike and Stevens, Susanne and Kahl, Christoph and Ruellan, Anne and Matthias, Kathrin and Kubin, Thomas and Stahlhut, Kerstin and Heider, Andrea and Lordick, Florian and Thomas, Michael}, title = {Impact of molecular alterations on quality of life and prognostic understanding over time in patients with incurable lung cancer: a multicenter, longitudinal, prospective cohort study}, series = {Supportive Care in Cancer}, volume = {30}, journal = {Supportive Care in Cancer}, number = {4}, organization = {Arbeitsgemeinschaft Palliativmedizin (APM) of the German Cancer Society (DKG)}, issn = {0941-4355}, doi = {10.1007/s00520-021-06736-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-308211}, pages = {3131-3140}, year = {2022}, abstract = {Purpose The purpose of this study is to investigate changes over time in quality of life (QoL) in incurable lung cancer patients and the impact of determinants like molecular alterations (MA). Methods In a prospective, longitudinal, multicentric study, we assessed QoL, symptom burden, psychological distress, unmet needs, and prognostic understanding of patients diagnosed with incurable lung cancer at the time of the diagnosis (T0) and after 3 (T1), 6 (T2) and 12 months (T3) using validated questionnaires like FACT-L, National Comprehensive Cancer Network (NCCN) Distress Thermometer (DT), PHQ-4, SCNS-SF-34, and SEIQoL. Results Two hundred seventeen patients were enrolled, 22 (10\%) with reported MA. QoL scores improved over time, with a significant trend for DT, PHQ-4, and SCNS-SF-34. Significant determinants for stable or improving scores over time were survival > 6 months, performance status at the time of diagnosis, and presence of MA. Patients with MA showed better QoL scores (FACT-L at T1 104.4 vs 86.3; at T2 107.5 vs 90.0; at T3 100.9 vs 92.8) and lower psychological distress (NCCN DT at T1 3.3 vs 5; at T2 2.7 vs 4.5; at T3 3.7 vs 4.5; PHQ-4 at T1 2.3 vs 4.1; at T2 1.7 vs 3.6; at T3 2.2 vs 3.6), but also a worsening of the scores at 1 year and a higher percentage of inaccurate prognostic understanding (27 vs 17\%) compared to patients without MA. Conclusion Patients with tumors harboring MA are at risk of QoL deterioration during the course of the disease. Physicians should adapt their communication strategies in order to maintain or improve QoL.}, language = {en} } @article{BernhardKrumpholzKriegeretal.2022, author = {Bernhard, Lukas and Krumpholz, Roman and Krieger, Yannick and Czempiel, Tobias and Meining, Alexander and Navab, Nassir and L{\"u}th, Tim and Wilhelm, Dirk}, title = {PLAFOKON: a new concept for a patient-individual and intervention-specific flexible surgical platform}, series = {Surgical Endoscopy}, volume = {36}, journal = {Surgical Endoscopy}, number = {7}, issn = {0930-2794}, doi = {10.1007/s00464-021-08908-x}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-307490}, pages = {5303-5312}, year = {2022}, abstract = {Background Research in the field of surgery is mainly driven by aiming for trauma reduction as well as for personalized treatment concepts. Beyond laparoscopy, other proposed approaches for further reduction of the therapeutic trauma have failed to achieve clinical translation, with few notable exceptions. We believe that this is mainly due to a lack of flexibility and high associated costs. We aimed at addressing these issues by developing a novel minimally invasive operating platform and a preoperative design workflow for patient-individual adaptation and cost-effective rapid manufacturing of surgical manipulators. In this article, we report on the first in-vitro cholecystectomy performed with our operating platform. Methods The single-port overtube (SPOT) is a snake-like surgical manipulator for minimally invasive interventions. The system layout is highly flexible and can be adapted in design and dimensions for different kinds of surgery, based on patient- and disease-specific parameters. For collecting and analyzing this data, we developed a graphical user interface, which assists clinicians during the preoperative planning phase. Other major components of our operating platform include an instrument management system and a non-sterile user interface. For the trial surgery, we used a validated phantom which was further equipped with a porcine liver including the gallbladder. Results Following our envisioned preoperative design workflow, a suitable geometry of the surgical manipulator was determined for our trial surgery and rapidly manufactured by means of 3D printing. With this setup, we successfully performed a first in-vitro cholecystectomy, which was completed in 78 min. Conclusions By conducting the trial surgery, we demonstrated the effectiveness of our PLAFOKON operating platform. While some aspects - especially regarding usability and ergonomics - can be further optimized, the overall performance of the system is highly promising, with sufficient flexibility and strength for conducting the necessary tissue manipulations.}, language = {en} } @article{DietzschBraesigkSeideletal.2022, author = {Dietzsch, Stefan and Braesigk, Annett and Seidel, Clemens and Remmele, Julia and Kitzing, Ralf and Schlender, Tina and Mynarek, Martin and Geismar, Dirk and Jablonska, Karolina and Schwarz, Rudolf and Pazos, Montserrat and Weber, Damien C. and Frick, Silke and Gurtner, Kristin and Matuschek, Christiane and Harrabi, Semi Ben and Gl{\"u}ck, Albrecht and Lewitzki, Victor and Dieckmann, Karin and Benesch, Martin and Gerber, Nicolas U. and Obrecht, Denise and Rutkowski, Stefan and Timmermann, Beate and Kortmann, Rolf-Dieter}, title = {Types of deviation and review criteria in pretreatment central quality control of tumor bed boost in medulloblastoma—an analysis of the German Radiotherapy Quality Control Panel in the SIOP PNET5 MB trial}, series = {Strahlentherapie und Onkologie}, volume = {198}, journal = {Strahlentherapie und Onkologie}, number = {3}, issn = {0179-7158}, doi = {10.1007/s00066-021-01822-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-307812}, pages = {282-290}, year = {2022}, abstract = {Purpose In Germany, Austria, and Switzerland, pretreatment radiotherapy quality control (RT-QC) for tumor bed boost (TB) in non-metastatic medulloblastoma (MB) was not mandatory but was recommended for patients enrolled in the SIOP PNET5 MB trial between 2014 and 2018. This individual case review (ICR) analysis aimed to evaluate types of deviations in the initial plan proposals and develop uniform review criteria for TB boost. Patients and methods A total of 78 patients were registered in this trial, of whom a subgroup of 65 patients were available for evaluation of the TB treatment plans. Dose uniformity was evaluated according to the definitions of the protocol. Additional RT-QC criteria for standardized review of target contours were elaborated and data evaluated accordingly. Results Of 65 initial TB plan proposals, 27 (41.5\%) revealed deviations of target volume delineation. Deviations according to the dose uniformity criteria were present in 14 (21.5\%) TB plans. In 25 (38.5\%) cases a modification of the RT plan was recommended. Rejection of the TB plans was rather related to unacceptable target volume delineation than to insufficient dose uniformity. Conclusion In this analysis of pretreatment RT-QC, protocol deviations were present in a high proportion of initial TB plan proposals. These findings emphasize the importance of pretreatment RT-QC in clinical trials for MB. Based on these data, a proposal for RT-QC criteria for tumor bed boost in non-metastatic MB was developed.}, language = {en} } @article{DuerrnagelBeyerThomaleetal.2022, author = {D{\"u}rrnagel, Matteo and Beyer, Jacob and Thomale, Ronny and Schwemmer, Tilman}, title = {Unconventional superconductivity from weak coupling}, series = {The European Physical Journal B}, volume = {95}, journal = {The European Physical Journal B}, number = {7}, issn = {1434-6028}, doi = {10.1140/epjb/s10051-022-00371-4}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-325153}, year = {2022}, abstract = {We develop a joint formalism and numerical framework for analyzing the superconducting instability of metals from a weak coupling perspective.
