The Lady in Pink: Dress and the Enigma of Gendered Space in Marcel Proust\u27s Fiction

A study of the role of clothing as central to issues of characterization, description and historical reference in Marcel Proust\u27s A la recherche du temps perdu. Focus on Odette de Crécy, one of the central characters in the novel, a courtesan who becomes the wife of Charles Swann but who first captivates the narrator\u27s imagination when, as a child, he briefly sees her as a Lady in Pink. Odette\u27s role as a fashionable woman, as one of the best-dressed women in Parisian society, gives unity to her character. The description of her clothing, however, not only provides the occasion for an accurate recreation of contemporary dress codes. The links between clothing and a woman\u27s body are explicitly explored in creating the character of Odette. Her femininity is defined specifically in terms of surfaces and objects and her personality seems to assume its reality from costume. Dress not only encloses her lovely appearance; it gives substance to her person and order to her life. Through the agency of dress this ordinary, even vulgar woman rises above her condition and enters a world of passion and poetry

Kommunikation, Konsens und Kohäsion im universitären Kontext

Gesellschaftlicher Zusammenhalt wird in Bildungseinrichtungen (Eckert 2007) als Teil eines individuellen, aber gesellschaftlich verantworteten Sozialisationsprozesses in den entsprechenden Lebensphasen (Abels et al. 2008) erfahren. Dafür sind Kommunikationsprozesse von Bedeutung, die entweder selbst zu einem Konsens führen oder in denen die Entstehung eines Konsenses nachvollzogen werden kann. In den kommunikativen Aushandlungsprozessen während eines Studiums werden Wissensbestände diskutiert und Wissensstrukturen aufgebaut. Studierende, aber auch Lehrende erleben so einen Lehr-Lernzusammenhang, der bestenfalls die Genese wissenschaftlichen Wissens verdeutlicht, und erkennen, dass gesättigtes wissenschaftliches Wissen vom Konsens der Beteiligten abhängig ist. Konsens führt damit zu einem geteilten Wissensbestand, der über den konkreten Lehrkontext hinaus Geltung hat und zu sozialer Kohäsion innerhalb der Universitätsgemeinschaft, darüber hinaus in der Scientific Community und in der Gesellschaft an sich führen kann. Dieser fragile Zusammenhang zwischen Kommunikation, Konsens und Kohäsion in der Wissenschaft ist abhängig von verfügbarem Wissen und damit von der Informationsbeschaffung. Veränderungen, wie sie während der Pandemie zu beobachten waren, als Bibliotheksbestände nurmehr digital zugänglich waren und alle Lehr- und Forschungsanstrengungen in die digitale Welt verlegt wurden (Breitenbach 2021), wirken sich deshalb direkt und indirekt auf die Kommunikation der Universitätsgemeinschaft (Mayrberger 2020; Morselli et al. 2021) aus. Deshalb muss die Frage gestellt werden, wie sich das wissenschaftliche, gesellschaftlich geteilte Wissen verändert und welche Auswirkung es haben kann, wenn nurmehr digitale Bestände und Medien genutzt werden können

Sequential anti-cytomegalovirus response monitoring may allow prediction of cytomegalovirus reactivation after allogeneic stem cell transplantation

Background: Reconstitution of cytomegalovirus-specific CD3+CD8+ T cells (CMV-CTLs) after allogeneic hematopoietic stem cell transplantation (HSCT) is necessary to bring cytomegalovirus (CMV) reactivation under control. However, the parameters determining protective CMV-CTL reconstitution remain unclear to date. Design and Methods: In a prospective tri-center study, CMV-CTL reconstitution was analyzed in the peripheral blood from 278 patients during the year following HSCT using 7 commercially available tetrameric HLA-CMV epitope complexes. All patients included could be monitored with at least CMV-specific tetramer. Results: CMV-CTL reconstitution was detected in 198 patients (71%) after allogeneic HSCT. Most importantly, reconstitution with 1 CMV-CTL per µl blood between day +50 and day +75 post-HSCT discriminated between patients with and without CMV reactivation in the R+/D+ patient group, independent of the CMV-epitope recognized. In addition, CMV-CTLs expanded more daramtaically in patients experiencing only one CMV-reactivation than those without or those with multiple CMV reactivations. Monitoring using at least 2 tetramers was possible in 63% (n = 176) of the patients. The combinations of particular HLA molecules influenced the numbers of CMV-CTLs detected. The highest CMV-CTL count obtained for an individual tetramer also changed over time in 11% of these patients (n = 19) resulting in higher levels of HLA-B*0801 (IE-1) recognizing CMV-CTLs in 14 patients. Conclusions: Our results indicate that 1 CMV-CTL per µl blood between day +50 to +75 marks the beginning of an immune response against CMV in the R+/D+ group. Detection of CMV-CTL expansion thereafter indicates successful resolution of the CMV reactivation. Thus, sequential monitoring of CMV-CTL reconstitution can be used to predict patients at risk for recurrent CMV reactivation

Grünlicht-induzierte Rezeptorinaktivierung durch Cobalamin-bindende Domänen

Optogenetik und Photopharmakologie ermöglichen präzise räumliche und zeitliche Kontrolle von Proteinwechselwirkung und -funktion in Zellen und Tieren. Optogenetische Methoden, die auf grünes Licht ansprechen und zum Trennen von Proteinkomplexen geeignet sind, sind nichtweitläufig verfügbar, würden jedoch mehrfarbige Experimente zur Beantwortung von biologischen Fragestellungen ermöglichen. Hier demonstrieren wir die Verwendung von Cobalamin(Vitamin B12)-bindenden Domänen von bakteriellen CarH-Transkriptionsfaktoren zur Grünlicht-induzierten Dissoziation von Rezeptoren. Fusioniert mit dem Fibroblasten-W achstumsfaktor-Rezeptor 1 führten diese im Dunkeln in kultivierten Zellen zu Signalaktivität durch Oligomerisierung, welche durch Beleuchten umgehend aufgehoben wurde. In Zebrafischembryonen, die einen derartigen Rezeptor exprimieren, ermöglichte grünes Licht die Kontrolle über abnormale Signalaktivität während der Embryonalentwicklung

SUMOylation of the mitochondrial fission protein Drpl occurs at multiple nonconsensus sites within the B domain and is linked to its activity cycle

Dynamin‐related protein (Drp) 1 is a key regulator of mitochondrial fission and is composed of GTP‐binding, Middle, insert B, and C‐terminal GTPase effector (GED) domains. Drpl associates with mitochondrial fission sites and promotes membrane constriction through its intrinsic GTPase activity. The mechanisms that regulate Drpl activity remain poorly understood but are likely to involve reversible post‐translational modifications, such as conjugation of small ubiquitin‐like modifier (SUMO) proteins. Through a detailed analysis, we find that Drpl interacts with the SUMO‐conjugating enzyme Ubc9 via multiple regions and demonstrate that Drpl is a direct target of SUMO modification by all three SUMO isoforms. While Drpl does not harbor consensus SUMOylation sequences, our analysis identified2 clusters of lysine residues within the B domain that serve as noncanonical conjugation sites. Although initial analysis indicates that mitochondrial recruitment of ectopically expressed Drpl in response to staurosporine is unaffected by loss of SUMOylation, we find that Drpl SUMOylation is enhanced in the context of the K38A mutation. This dominant‐negative mutant, which is deficient in GTP binding and hydrolysis, does not associate with mitochondria and prevents normal mitochondrial fission. This finding suggests that SUMOylation of Drpl is linked to its activity cycle and is influenced by Drpl localization.—Figueroa‐Romero, C., Iniguez‐Lluhi, J.

Linking heart rate variability to psychological health and brain structure in adolescents with and without conduct disorder

AimsHeart rate variability (HRV) measures have been suggested in healthy individuals as a potential index of self-regulation skills, which include both cognitive and emotion regulation aspects. Studies in patients with a range of psychiatric disorders have however mostly focused on the potential association between abnormally low HRV at rest and specifically emotion regulation difficulties. Emotion regulation deficits have been reported in patients with Conduct Disorder (CD) however, the association between these emotion regulation deficits and HRV measures has yet to be fully understood. This study investigates (i) the specificity of the association between HRV and emotion regulation skills in adolescents with and without CD and (ii) the association between HRV and grey matter brain volumes in key areas of the central autonomic network which are involved in self-regulation processes, such as insula, lateral/medial prefrontal cortices or amygdala.MethodsRespiratory sinus arrhythmia (RSA) measures of HRV were collected from adolescents aged between 9–18 years (693 CD (427F)/753 typically developing youth (TD) (500F)), as part of a European multi-site project (FemNAT-CD). The Inverse Efficiency Score, a speed-accuracy trade-off measure, was calculated to assess emotion and cognitive regulation abilities during an Emotional Go/NoGo task. The association between RSA and task performance was tested using multilevel regression models. T1-weighted structural MRI data were included for a subset of 577 participants (257 CD (125F); 320 TD (186F)). The CerebroMatic toolbox was used to create customised Tissue Probability Maps and DARTEL templates, and CAT12 to segment brain images, followed by a 2 × 2 (sex × group) full factorial ANOVA with RSA as regressor of interest.ResultsThere were no significant associations between RSA and task performance, neither during emotion regulation nor during cognitive regulation trials. RSA was however positively correlated with regional grey matter volume in the left insula (pFWE = 0.011) across all subjects.ConclusionRSA was related to increased grey matter volume in the left insula across all subjects. Our results thus suggest that low RSA at rest might be a contributing or predisposing factor for potential self-regulation difficulties. Given the insula’s role in both emotional and cognitive regulation processes, these brain structural differences might impact either of those
