Binding accounts propose that action planning involves temporarily binding codes of the action's unique features, such as its location and duration. Such binding becomes evident when another action (B) is initiated while maintaining the Action Plan A. Action B is usually impaired if it partially overlaps with the planned Action A (as opposed to full or no feature overlap).

The interplay of personality pathology and treatment outcome in psychosomatic psychotherapy: A longitudinal analysis using latent change score modelling.

Compr Psychiatry

November 2024

Department of Psychotherapy and Psychosomatic Medicine, Faculty of Medicine and University Hospital Carl Gustav Carus, TUD Dresden University of Technology, Fetscherstraße 74, 01307 Dresden, Germany; Department of Clinical Psychology, Institute of Psychology, Friedrich-Schiller University Jena, Am Steiger 3-1, 07743 Jena, Germany; German Center for Mental Health (DZPG), Site Halle-Jena-Marburg, Germany.

Introduction: While ample data demonstrate the effectiveness of inpatient psychosomatic treatment, clinical observation and empirical evidence demonstrate that not all patients benefit equally from established therapeutic methods. Especially patients with a comorbid personality disorder often show reduced therapeutic success compared to other patient groups. Due to the heterogeneous and categorical personality assessment, previous studies indicated no uniform direction of this influence.

Bacterial aggregation triggered by low-level antibiotic-mediated lysis.

NPJ Biofilms Microbiomes

September 2024

School of Physics and Astronomy, University of Edinburgh, Edinburgh, UK.

Suspended bacterial aggregates play a central role in ocean biogeochemistry, industrial processes and probably many clinical infections - yet the factors that trigger aggregation remain poorly understood, as does the relationship between suspended aggregates and surface-attached biofilms. Here we show that very low doses of cell-wall targeting antibiotic, far below the minimal inhibitory concentration, can trigger aggregation of Escherichia coli cells. This occurs when a few cells lyse, releasing extracellular DNA - thus, cell-to-cell variability in antibiotic response leads to population-level aggregation.

Enzymatic parameters are classically determined in vitro, under conditions that are far from those encountered in cells, casting doubt on their physiological relevance. We developed a generic approach combining tools from synthetic and systems biology to measure enzymatic parameters in vivo. In the context of a synthetic carotenoid pathway in Saccharomyces cerevisiae, we focused on a phytoene synthase and three phytoene desaturases, which are difficult to study in vitro.

Synthetic Biology of Photosynthetic Organisms, Matthias Schleiden Institute for Genetics, Bioinformatics and Molecular Botany, Friedrich Schiller University Jena, Jena, Germany.

Extracellular proteins play a significant role in shaping microbial communities which, in turn, can impact ecosystem function, human health, and biotechnological processes. Yet, for many ubiquitous microbes, there is limited knowledge regarding the identity and function of secreted proteins. Here, we introduce EXCRETE (enhanced exoproteome characterization by mass spectrometry), a workflow that enables comprehensive description of microbial exoproteomes from minimal starting material.

Harsh and unsupportive parenting is a risk factor for the development of disruptive behavior in children. However, little is known about how children's temperament and stress reactivity influence this relation. In a three-wave longitudinal study, we examined whether the associations between parenting practices (supportive parenting, positive discipline, and harsh discipline) and child disruptive behavior were mediated by child temperament (negative emotionality) and stress reactivity (heart rate reactivity).

Kiezdeutsch is a multiethnolectal variety of German spoken by young people from multicultural communities that exhibits lexical, syntactic, and phonetic differences from standard German. A rather salient and pervasive feature of this variety is the fronting of the standard palatal fricative /ç/ (as in "I") to [ɕ] or [ʃ]. Previous perception work shows that this difference is salient and carries social meaning but dependent on the listener group.

Evaluation of Nontargeted Mass Spectral Data Acquisition Strategies for Water Analysis and Toxicity-Based Feature Prioritization by MS2Tox.

Environ Sci Technol

October 2024

Department of Materials and Environmental Chemistry, Stockholm University, Svante Arrhenius Väg 16, SE-106 91, Stockholm, Sweden.

The machine-learning tool MS2Tox can prioritize hazardous nontargeted molecular features in environmental waters, by predicting acute fish lethality of unknown molecules based on their MS spectra, prior to structural annotation. It has yet to be investigated how the extent of molecular coverage, MS spectra quality, and toxicity prediction confidence depend on sample complexity and MS data acquisition strategies. We compared two common nontargeted MS acquisition strategies with liquid chromatography high-resolution mass spectrometry for structural annotation accuracy by SIRIUS+CSI:FingerID and MS2Tox toxicity prediction of 191 reference chemicals spiked to LC-MS water, groundwater, surface water, and wastewater.
