Therapy of acute myeloid leukemia (AML) is unsatisfactory. Histone deacetylase inhibitors (HDACi) are active against leukemic cells in vitro and in vivo. Clinical data suggest further testing of such epigenetic drugs and to identify mechanisms and markers for their efficacy. Primary and permanent AML cells were screened for viability, replication stress/DNA damage, and regrowth capacities after single exposures to the clinically used pan-HDACi panobinostat (LBH589), the class I HDACi entinostat/romidepsin (MS-275/FK228), the HDAC3 inhibitor RGFP966, the HDAC6 inhibitor marbostat-100, the non-steroidal anti-inflammatory drug (NSAID) indomethacin, and the replication stress inducer hydroxyurea (HU). Immunoblotting was used to test if HDACi modulate the leukemia-associated transcription factors β-catenin, Wilms tumor (WT1), and myelocytomatosis oncogene (MYC). RNAi was used to delineate how these factors interact. We show that LBH589, MS-275, FK228, RGFP966, and HU induce apoptosis, replication stress/DNA damage, and apoptotic fragmentation of β-catenin. Indomethacin destabilizes β-catenin and potentiates anti-proliferative effects of HDACi. HDACi attenuate WT1 and MYC caspase-dependently and -independently. Genetic experiments reveal a cross-regulation between MYC and WT1 and a regulation of β-catenin by WT1. In conclusion, reduced levels of β-catenin, MYC, and WT1 are molecular markers for the efficacy of HDACi. HDAC3 inhibition induces apoptosis and disrupts tumor-associated protein expression.
Web spiders connect silk proteins, so-called spidroins, into fibers of extraordinary toughness. The spidroin N-terminal domain (NTD) plays a pivotal role in this process: it polymerizes spidroins through a complex mechanism of dimerization. Here we analyze sequences of spidroin NTDs and find an unusually high content of the amino acid methionine. We simultaneously mutate all methionines present in the hydrophobic core of a spidroin NTD from a nursery web spider’s dragline silk to leucine. The mutated NTD is strongly stabilized and folds at the theoretical speed limit. The structure of the mutant is preserved, yet its ability to dimerize is substantially impaired. We find that side chains of core methionines serve to mobilize the fold, which can thereby access various conformations and adapt the association interface for tight binding. Methionine in a hydrophobic core equips a protein with the capacity to dynamically change shape and thus to optimize its function.
Purpose: The aim of this study is to record material- and surface-dependent heat dissipation during the process of inserting implants into native animal bone. Materials and Methods: Implants made of titanium and zirconium that were identical in macrodesign were inserted under controlled conditions into a bovine rib tempered to 37 °C. The resulting surface temperature was measured on two bone windows by an infrared camera. The results of the six experimental groups, ceramic machined (1), sandblasted (2), and sandblasted and acid-etched surfaces (3) versus titanium implants with the corresponding surfaces (4, 5, and 6) were statistically tested. Results: The average temperature increase, 3 mm subcrestally at ceramic implants, differed with high statistical significance (p = 7.163 × 10−9, resulting from group-adjusted linear mixed-effects model) from titanium. The surface texture of ceramic implants shows a statistical difference between group 3 (15.44 ± 3.63 °C) and group 1 (19.94 ± 3.28 °C) or group 2 (19.39 ± 5.73 °C) surfaces. Within the titanium implants, the temperature changes were similar for all surfaces. Conclusion: Within the limits of an in vitro study, the high temperature rises at ceramic versus titanium implants should be limited by a very slow insertion velocity.
The group of neurodegenerative diseases, Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA) all exhibit inclusions containing amyloid-type α-synuclein (α-syn) aggregates within degenerating brain cells. α-syn also exists as soluble oligomeric species that are hypothesized to represent intermediates between its native and aggregated states. These oligomers are present in brain extracts from patients suffering from synucleinopathies and hold great potential as biomarkers. Although easily prepared in vitro, oligomers are metastable and dissociate over time, thereby complicating α-syn oligomer research. Using the small amine-reactive cross-linker, formaldehyde (FA), we successfully stabilized α-syn oligomers without affecting their size, overall structure or antigenicity towards aggregate-conformation specific α-syn antibodies FILA and MJFR-14-6-4-2. Further, cross-linked α-syn oligomers show resistance towards denaturant like urea and SDS treatment and remain fully functional as internal standard in an aggregation-specific enzyme-linked immunosorbent assay (ELISA) despite prior incubation with urea. We propose that FA cross-linked α-syn oligomers could serve as important calibrators to facilitate comparative and standardized α-syn biomarker studies going forward.
Narratives 2.0 : a multi-dimensional approach to semi-public storytelling in WhatsApp voice messages
(2019)
Based on a corpus of voice message narratives in German WhatsApp group chats, the present study contributes to research on social media storytelling in that it focusses on stories of personal experience which are embedded in a communication platform which favours a continuous dialogic exchange, narrated to well-defined non-anonymous publics and multimodal (comprised of visual and audible posting types). To capture the characteristics of this type of social media storytelling, the paper argues that Ochs and Capps’ (2001) dimensional model originally developed for conversational narratives (including the dimensions of tellability, tellership, embeddedness, linearity, moral stance) should be expanded by the dimensions of publicness, multimodality and sequencing. The prototype of storytelling in WhatsApp group chats is based on recent personal experiences; it is related by a single teller as an initial, sequentially non-embedded and linearly organised “big package” story (in a single voice message sometimes introduced by a text message containing an abstract); other group members routinely document their evaluative stances in rather conventionalised text message responses in the semi-public group space.
This contribution aims to describe privacy, publicness and anonymity as essential analytic dimensions for media linguistic research. The dimensions are not inherent in and predetermined by the technical features and forms of communication provided by mobile devices, but are used by the participants as an orientation grid for shaping their online and offline practices in and with mobile media. Considering both mobile device use in the public realm and the dissemination of increasingly private content in social media (which is said to lead to ‘blurred boundaries’ between the private and the public), the paper provides a brief overview of the main developments in mobile media research: Studies adopting various approaches – e. g. sociological-ethnographic, linguistic and media studies – illustrate how publicness, privacy and anonymity are actively shaped and brought about by mobile media users in face-to-face and remote social encounters. As this shows that publicness, privacy and anonymity are still relevant concepts for users, future media linguistics studies should focus on the dynamic multimodal practices by which they are contextualized and accomplished.
Die peripartale Depression tritt während der Schwangerschaft und in den 12 Monaten nach der Geburt auf. Zusätzlich zu Symptomen einer depressiven Episode ist die peripartale Depression durch schwangerschafts- oder kindbezogene Symptome wie infantizidale Vorstellungen, Gefühlslosigkeit gegenüber dem Kind, Versagensängste oder Insuffizienzgefühle als Mutter gekennzeichnet. Die Prävalenz liegt bei 7 bis 10 % präpartal und 7 bis 20 % postpartal. Folge ist ein erhöhtes Risiko für frühzeitige Wehentätigkeit, geringes Geburtsgewicht, intrauterine Wachstumsstörungen, Verhaltensstörungen und gestörte kognitive Entwicklung des Kindes. Außerdem steigt die Wahrscheinlichkeit für Mutter und Kind, im weiteren Leben erneut an einer Depression zu erkranken. Therapieoptionen stehen insbesondere psychotherapeutische Verfahren wie Interpersonelle Psychotherapie und Kognitive Verhaltenstherapie und eine antidepressive Therapie zur Verfügung.
Ziel der Arbeit war es, die Publikationen zu Depression und Schwangerschaft nach szientometrischen Kriterien zu analysieren und Charakteristika und Tendenzen der Forschung zu erkennen und zu interpretieren.
Nach Definition des Suchbegriffes wurden mithilfe der Datenbank Web of Science bzw. Web of Science Core Collection alle Publikationen zu Depression im Rahmen der Schwangerschaft von 1900 bis 2012 inklusive aller bibliometrischer Daten analysiert. Die Daten wurden nach Bereinigung hinsichtlich qualitativer Gesichtspunkte und szientometrischer Parameter wie Zitierungen, Zitationsrate und modifiziertem h-Index der Publikationen, Autoren, Institutionen und Nationen untersucht. Dabei wurden zusätzlich Genderaspekte und sozioökonomische Faktoren berücksichtigt.
Insgesamt wurden 7.330 Veröffentlichungen zu Pregnancy and Depression analysiert. 95,9 % davon waren in englischer Sprache veröffentlicht. Seit 1982 konnte eine kontinuierliche Zunahme der jährlichen Publikationen verzeichnet werden. Die Zahl der Zitierungen stieg seit 1979 ebenso jährlich an. Dabei sank die Zitationsrate seit 1990. Besonders viele Arbeiten wurden im Journal of Affective Disorders und im Archives of Womens Mental Health veröffentlicht. Unter den Forschungseinrichtungen fielen die Harvard University und St. George’s, University of London durch besonders viele Publikationen auf.
Wichtigste Wissenschaftsstandorte waren die USA, Großbritannien, Australien und Kanada, was sich in den meisten Publikationen, Zitierungen und den höchsten modifizierten h Indizes äußerte, gefolgt von meist europäischen Staaten. Unter Berücksichtigung sozioökonomischer Faktoren ergaben sich mehrere Besonderheiten: Die skandinavischen Staaten Norwegen, Schweden und Finnland finden sich unter den produktivsten Ländern nach Bereinigung um die Bevölkerungszahl. Nationen mit mittlerem und niedrigem Einkommen (Low- and middle income countries = LAMICs) wie Pakistan, Südafrika und Äthiopien leisten einen relevanten Beitrag zur Forschung, berücksichtigt man das Bruttoinlandsprodukt oder die Zahl der Wissenschaftler. Internationale Kooperation dieser Nationen entstanden insbesondere mit Großbritan-nien. Durch diese Zusammenarbeit wurde einerseits auf die höhere Prävalenz von Perinataler Depression in Entwicklungs und Schwellenländern hingewiesen. Andererseits wurde die schwangerschaftsassoziierte Depression als wichtiges Element von Global Mental Health anerkannt.
Seit 1992 veröffentlichen pro Jahr mehr Frauen als Männer zu Peripartaler Depression. Die weibliche Autorenschaft liegt bei 63 %. Unter den produktivsten Wissenschaftlern sind 8 Autorinnen und 6 Autoren. Die produktivsten Autoren sind die US Amerikanerin K.L. Wisner und die Britin L. Murray. Letztere wurde am häufigsten zitiert und führt die Liste der modifizierten h Indizes mit einem Wert von 68 an. Für den britischen Autor und Begründer des Screening-Instruments Edinburgh Postnatal Depression Scale (EPDS) J.L. Cox wurde die höchste Zitationsrate berechnet.
Im Gegensatz zu Veröffentlichungen in gynäkologischen Fachzeitschriften oder szientometrischen Arbeiten zu psychiatrischen Erkrankungen wie Schizophrenie ist der Frauenanteil in allen untersuchten Teilbereichen dem Männeranteil überlegen. Einzige Ausnahme ist die Letztautorenschaft. Diese Ergebnisse stellen eine Besonderheit dar, da eine weibliche Dominanz der Wissenschaft im Schnittbereich zwischen Psychiatrie, Psychosomatik, Psychologie und Frauenheilkunde bisher nicht beschrieben ist.
Comprehensive landscape of active deubiquitinating enzymes profiled by advanced chemoproteomics
(2019)
Enzymes that bind and process ubiquitin, a small 76-amino-acid protein, have been recognized as pharmacological targets in oncology, immunological disorders, and neurodegeneration. Mass spectrometry technology has now reached the capacity to cover the proteome with enough depth to interrogate entire biochemical pathways including those that contain DUBs and E3 ligase substrates. We have recently characterized the breast cancer cell (MCF7) deep proteome by detecting and quantifying ~10,000 proteins, and within this data set, we can detect endogenous expression of 65 deubiquitylating enzymes (DUBs), whereas matching transcriptomics detected 78 DUB mRNAs. Since enzyme activity provides another meaningful layer of information in addition to the expression levels, we have combined advanced mass spectrometry technology, pre-fractionation, and more potent/selective ubiquitin active-site probes with propargylic-based electrophiles to profile 74 DUBs including distinguishable isoforms for 5 DUBs in MCF7 crude extract material. Competition experiments with cysteine alkylating agents and pan-DUB inhibitors combined with probe labeling revealed the proportion of active cellular DUBs directly engaged with probes by label-free quantitative (LFQ) mass spectrometry. This demonstrated that USP13, 39, and 40 are non-reactive to probe, indicating restricted enzymatic activity under these cellular conditions. Our extended chemoproteomics workflow increases depth of covering the active DUBome, including isoform-specific resolution, and provides the framework for more comprehensive cell-based small-molecule DUB selectivity profiling.
Age Related Macular Degeneration (AMD) is the first cause of social blindness in people aged over 65 leading to atrophy of retinal pigment epithelial cells (RPE), photoreceptors and choroids, eventually associated with choroidal neovascularization. Accumulation of undigested cellular debris within RPE cells or under the RPE (Drusen), oxidative stress and inflammatory mediators contribute to the RPE cell death. The major risk to develop AMD is the Y402H polymorphism of complement factor H (CFH). CFH interacting with oxidized phospholipids on the RPE membrane modulates the functions of these cells, but the exact role of CFH in RPE cell death and survival remain poorly understood. The aim of this study was to analyze the potential protective mechanism of CFH on RPE cells submitted to oxidative stress. Upon exposure to oxidized lipids 4-HNE (4-hydroxy-2-nonenal) derived from photoreceptors, both the human RPE cell line ARPE-19 and RPE cells derived from human induced pluripotent stem cells were protected from death only in the presence of the full length human recombinant CFH in the culture medium. This protective effect was independent from the membrane attack complex (MAC) formation. CFH maintained RPE cells tight junctions’ structure and regulated the caspase dependent apoptosis process. These results demonstrated the CFH anti-oxidative stress functions independently of its capacity to inhibit MAC formation.
Critique, and especially radical critique of reason, is under pressure from two opponents. Whereas the proponents of "post-critical" or "acritical" thinking denounce critique as an empty and self-righteous repetition of debunking, the decriers of "post-truth" accuse critique of having helped to bring about our current "post-truth" politics. Both advocate realism as a limit critique must respect, but Vogelmann defends the claim that we urgently need radical critiques of reason because they offer a more precise diagnosis of the untruths in politics the two opponents of critique are rightfully worried about. Radical critiques of reason are possible, he argues, if we turn our attention to the practices of criticizing, if we refrain from a sovereign epistemology, and if we pluralize reason without trivializing it. In order to demonstrate the diagnostic advantage of radical critiques of reason, he briefly analyzes the political and epistemic strategy at work in two exemplary untruths in politics.

Background and Aims: Vitamin D has an inhibitory role in the inflammatory signaling pathways and supports the integrity of the intestinal barrier. Due to its immunomodulatory effect, vitamin D plays a role in chronic inflammatory bowel disease (IBD) and a deficiency is associated with an increased risk for a flare. We aimed to investigate to what extent the 25-hydroxyvitamin D (25(OH)D3) level correlates with disease activity and whether a cut-off value can be defined that discriminates between active disease and remission. Methods: Patients with IBD, treated at the University Hospital Frankfurt were analyzed retrospectively. The 25(OH)D3 levels were correlated with clinical activity indices and laboratory chemical activity parameters. A deficiency was defined as 25(OH)D3 levels <30 ng/mL. Results: A total of 470 (257 female) patients with IBD were included, 272 (57.9%) with Crohn’s disease (CD), 198 (42.1%) with ulcerative colitis (UC). The median age of the patients was 41 (18–84). In 283 patients (60.2%), a vitamin D deficiency was detected. 245 (53.6%) patients received oral vitamin D supplementation, and supplemented patients had significantly higher vitamin D levels (p < 0.0001). Remission, vitamin D substitution, and male gender were independently associated with the 25(OH)D3 serum concentration in our cohort in regression analysis. A 25(OH)D3 serum concentration of 27.5 ng/mL was the optimal cut-off value. Conclusion: Vitamin D deficiency is common in IBD patients and appears to be associated with increased disease activity. In our study, vitamin D levels were inversely associated with disease activity. Thus, close monitoring should be established, and optimized supplementation should take place.
The multifaceted p21 (Cip1/Waf1/CDKN1A) in cell differentiation, migration and cancer therapy
(2019)
Loss of cell cycle control is characteristic of tumorigenesis. The protein p21 is the founding member of cyclin-dependent kinase inhibitors and an important versatile cell cycle protein. p21 is transcriptionally controlled by p53 and p53-independent pathways. Its expression is increased in response to various intra- and extracellular stimuli to arrest the cell cycle ensuring genomic stability. Apart from its roles in cell cycle regulation including mitosis, p21 is involved in differentiation, cell migration, cytoskeletal dynamics, apoptosis, transcription, DNA repair, reprogramming of induced pluripotent stem cells, autophagy and the onset of senescence. p21 acts either as a tumor suppressor or as an oncogene depending largely on the cellular context, its subcellular localization and posttranslational modifications. In the present review, we briefly mention the general functions of p21 and summarize its roles in differentiation, migration and invasion in detail. Finally, regarding its dual role as tumor suppressor and oncogene, we highlight the potential, difficulties and risks of using p21 as a biomarker as well as a therapeutic target.
Introduction: Definitive chemoradiation (CRT) followed by high-dose-rate (HDR) brachytherapy (BT) represents state-of-the-art treatment for locally-advanced cervical cancer. Despite use of this treatment paradigm, disease-related outcomes have stagnated in recent years, indicating the need for biomarker development and improved patient stratification. Here, we report the association of Polo-like kinase (PLK) 3 expression and Caspase 8 T273 phosphorylation levels with survival among patients with cervical squamous cell carcinoma (CSCC) treated with CRT plus BT.
Methods: We identified 74 patients with FIGO Stage Ib to IVb cervix squamous cell carcinoma. Baseline immunohistochemical scoring of PLK3 and pT273 Caspase 8 levels was performed on pre-treatment samples. Correlation was then assessed between marker expression and clinical endpoints, including cumulative incidences of local and distant failure, cancer-specific survival (CSS) and overall survival (OS). Data were then validated using The Cancer Genome Atlas (TCGA) dataset.
Results: PLK3 expression levels were associated with pT273 Caspase 8 levels (p = 0.009), as well as N stage (p = 0.046), M stage (p = 0.026), and FIGO stage (p = 0.001). By the same token, pT273 Caspase 8 levels were associated with T stage (p = 0.031). Increased PLK3 levels corresponded to a lower risk of distant relapse (p = 0.009), improved CSS (p = 0.001), and OS (p = 0.003). Phospho T273 Caspase 8 similarly corresponded to decreased risk of distant failure (p = 0.021), and increased CSS (p < 0.001) and OS (p < 0.001) and remained a significant predictor for OS on multivariate analysis. TCGA data confirmed the association of low PLK3 expression with resistance to radiotherapy and BT (p < 0.05), as well as increased propensity for metastasis (p = 0.019). Finally, a combined PLK3 and pT273 Caspase 8 score predicted for decreased distant relapse (p = 0.005), and both improved CSS (p < 0.001) and OS (p < 0.001); this combined score independently predicted distant failure (p = 0.041) and CSS (p = 0.003) on multivariate analyses.
Conclusion: Increased pre-treatment tumor levels of PLK3 and pT273 Caspase 8 correspond to improved disease-related outcomes among cervical cancer patients treated with CRT plus BT, representing a potential biomarker in this context.
Introduction: Our aim was to highlight the characteristics of pediatric Meckel's diverticulum with a special focus on its complications.
Methods: We report a group of seven patients with Meckel's diverticulum and its resection from the Department of Pediatric Surgery between 2012 and 2017. We reviewed all patient records, clinical presentation, and intraoperative findings. The diagnosis was confirmed by surgery and pathology. For a systematic literature review, we used PubMed, Medline and Google Scholar search engines to locate articles containing terms such as Meckel's diverticulum, children, pediatric, complications and symptomatic. We included article reporting on case series in English and German on pediatric patients only.
Results: All included patients (n = 7) were symptomatic. Some patients showed isolated symptoms, and others presented with a combination of symptoms that consisted of abdominal pain, bloody stool or vomiting. The median age of our seven cases was 3.5 years, including 4 male and 3 female patients. Intestinal obstruction was the most common complication; it was seen in 5 out of 7 patients (intussusception in 4 cases, volvulus in 1 case). Ectopic gastric tissue was identified in 3 cases, and inclusion of pancreatic tissue was observed in 1 case. The literature review identified 8 articles for a total of 641 patients aged between 1 day and 17 years and a male:female ratio of 2.6:1. From this group, 528 patients showed clinical symptoms related to Meckel's diverticulum. The most common symptom was abdominal pain and bloody stool. The most common surgical finding in symptomatic patients was intestinal obstruction (41%), followed by intestinal hemorrhage (34%). Complications such as perforation (10%) and diverticulitis (13%) were less frequently reported. Heterotopic tissue was confirmed on histopathology in 53% of all patients enclosing gastric, pancreatic, and both gastric and pancreatic mucosae. In one case, large intestine tissue could be found. Overall, one death was reported.
Conclusion: The presented case series and literature review found similar clinical presentations and complications of Meckel's diverticulum in children. Intestinal obstruction and bleeding are more frequent than inflammation in pediatric Meckel's diverticulum. Bowel obstruction is the leading cause for complicated Meckel's diverticulum in patients younger than 12 years.
About 200 years ago, legal concepts based on the idea of formal equality prevailed. Over the last 150 years, however, the law has tried on a large scale to establish substantive equality, or at least to alleviate social and economic imbalances. To this day, the law which has undertaken this task has grown in scope and become increasingly differentiated. It has become one of the most important components of modern legal systems and has a history with its own distinctive contours. The terms used to summarise the corresponding legal materials are manifold: law of the welfare state, law of the provident state (état providence) (François Ewald), social law, social welfare law, etc. ...
The use of contractual engineering to create channels of credit intermediation outside of the realm of banking regulation has been a recurring activity in Western financial systems over the last 50 years. After the financial crisis of 2007 and 2008, this phenomenon, at that time commonly referred to as ‘shadow banking’, evoked a large-scale regulatory backlash, including several specific regulatory constraints being placed on non-bank financial institutions (NBFI). This paper proposes a different avenue for regulators to keep regulatory arbitrage under control and preserve sufficient space for efficient financial innovation. Rather than engaging in the proverbial race between hare and hedgehog that is emerging with increasingly specific regulation of particular contractual arrangements, this paper argues for a normative approach to supervision. We outline this approach in detail by showing that regulators should primarily analyse the allocation of tail risk inherent in the respective contractual arrangements. Our paper proposes to assign regulatory burdens equivalent to prudential banking regulation, in case these arrangements become only viable through indirect or direct access to an (ad hoc) public backstop. In order to make the pivotal assessment, regulators will need information about recent contractual innovations and their risk-allocating characteristics. According to the scholarship on regulatory networks serving as communities of interpretation, we suggest in particular how regulators should structure their relationships with semi-public gatekeepers such as lawyers, auditors and consultants to keep abreast of the real-world implications of evolving transactional structures. This paper then uses the rise of credit funds as a non-bank entities economically engaged in credit intermediation to apply this normative framework, pointing to recent contractual innovations that call for more regulatory scrutiny in a multipolar regulatory dialogue.
The article analyses how the decrees of the Council of Trent regarding marriage were used by the Church of Rome as a tool to contrast mixed marriages in Early Modern Europe. It investigates how these decrees were evaded by local churches in order to administer a practice of confessional coexistence impossible to eradicate, and how they were manipulated by actors – even Protestants – to put an end to undesirable unions. It also presents the interpretation that the Church of Rome made of the Tametsi to resolve the age-old issue of mixed marriages in the Low Countries, issuing the Benedictine Declaration, later applied to other contexts with a strong Protestant presence – above all out-side Europe. Although the Council of Trent claimed to have fixed a homogeneous and flawless nuptial ritual, the various local practices did not always adapt to it. Indeed, they bypassed it; sometimes refused it. This led parish priests and missionaries to turn to Rome for the resolution of concrete cases. The decisions taken for individual cases became a normative reference point. It was produced by the continuous interaction and negotiation with local churches and went on in fact to profoundly influence the sacramental rituality of marriages, which Tametsi had claimed were fixed and immutable.
Worldwide, academics and practitioners are developing ‘planning-oriented’ approaches to reduce the negative impacts of car traffic for more sustainable urban and transport development. One such example is the design of car-reduced neighborhoods, although these are controversial issues in the hegemonic ‘system’ of automobility. Despite the reduction of emissions and frequent recognition as ‘best practice examples’, ‘planning-critical’ research questions the underlying objectives and narratives of such sustainable developments. Our study contributes to this research perspective by improving the understanding of narratives that emerge along with car-reduced housing developments. For this purpose, we analyze two car-reduced neighborhoods in the City of Darmstadt (Germany) by conducting interviews with different actors involved in the planning and implementation processes. Our investigation reveals that the development of car-reduced neighborhoods (i) is consciously embedded in the context of sustainability, (ii) is characterized by power relations, (iii) follows normative indicators, and (iv) does not always correspond to lived realities. Altogether, the traced narratives of car-reduced neighborhoods are embedded in the overarching debate on sustainability, while at the same time revealing the dependence of society on the automobile. Thus, the hegemonic ‘system’ of automobility—although it is beginning to crack—continues to exist.
The 100th anniversary of the Weimar Constitution’s promulgation has brought a number of new stimuli to a historiography that has for a long time focused largely on the Weimar Republic’s failure. Two prominent recent publications – Udo Di Fabio’s study and a collective volume edited by Horst Dreier und Christian Waldhoff – are reviewed in this issue by the Brazilian constitutional historian Marcelo Neves. His review and the last months’ public debate on the merits and flaws of the Weimar Constitution in Germany, which was framed by current concerns about the state of Western democracies, show to what extent constitutional history is always also a conversation about the present. ...
