Background: Multiple Sclerosis (MS) is an autoimmune disease associated with physical disability, psychological impairment, and cognitive dysfunctions. Consequently, the disease burden is substantial, and treatment choices are limited. In this randomized, double-blind study, we conducted repeated prefrontal electrical stimulation in 40 patients with MS to evaluate mental health variables (quality of life, sleep difficulties, psychological distress) and cognitive dysfunctions (psychomotor speed, working memory, attention/vigilance), marking it as the third largest sample size tDCS research conducted in MS to date.

Department of Psychology and Neurosciences, Leibniz Research Centre for Working Environment and Human Factors, Dortmund, Germany; Bielefeld University, University Hospital OWL, Protestant Hospital of Bethel Foundation, University Clinic of Psychiatry and Psychotherapy, Bielefeld, Germany; German Centre for Mental Health (DZPG), Bochum, Germany. Electronic address:

Background: Brain oscillations in the delta frequency band have been linked with deep sleep and consolidation of declarative memory during sleep. However, the causal relationship of these associations remains not competely clarified, primarily due to constraints by technical limitations of brain stimulation approaches suited to induce and stabilize respective oscillatory activity in the human brain. The objective of this study was to establish a non-invasive brain stimulation protocol capable of reliably inducing, and stabilizing respective oscillatory activity in the delta frequency range.

The kidney is the main organ that senses changes in systemic O pressure by hypoxia-PHD-HIFa (HPH) signaling, resulting in adaptive target gene activation, including erythropoietin (EPO). The non-essential transition metal cadmium (Cd) is nephrotoxic and disrupts the renal HPH pathway, which may promote Cd-associated chronic renal disease (CKD). A deeper molecular understanding of Cd interference with renal HPH signaling is missing, and no data with renal cell lines are available.

Parenting stress, dyadic coping and endocrine markers of stress and resilience in foster and biological mothers.

PLoS One

September 2024

Medical Faculty, Department of Child and Adolescent Psychiatry, Child Neuropsychology Section, Psychosomatics and Psychotherapy, RWTH Aachen University, Aachen, Germany.

Foster parents have been shown to report higher levels of parenting stress but also more dyadic coping (DC) behaviors in their partnership than biological parents, which might be an important protective factor that helps them cope with daily stressors. Here, we examined how parenting stress and DC are related in foster and biological parents and whether these are reflected in long-term alterations of hypothalamic-pituitary-adrenocortical (HPA) axis activity. A total of 79 foster mothers and 131 biological mothers participated in a longitudinal study.

Feeling tired versus feeling relaxed: Two faces of low physiological arousal.

PLoS One

September 2024

Neuro-cognitive Psychology and Center of Cognitive Interaction Technology (CITEC), Bielefeld University, Bielefeld, Germany.

Human well-being and functioning depend on two fundamental mental states: Relaxation and sleepiness. Relaxation and sleepiness are both assumed to be states of low physiological arousal and negatively correlated. However, it is still unclear how consistent this negative relationship is across different settings and whether it changes before and after an intervention.

Narratives of contingency and practices of comparing in the emergence of German molecular genetics (1958-1968).

Stud Hist Philos Sci

October 2024

Department of History, Bielefeld University, D 33501, Bielefeld, Germany. Electronic address:

This article explores the emergence of molecular approaches in German genetic research during the 1958-1968 decade as a period of contingency and alternative possibilities. We introduce "Narratives of Contingency" as an analytical framework to examine how scientists construct a specific narrative - linking past experiences with expectations of future conditions - in order to outline and navigate pathway-decisions in the present. We apply this framework to Hans-Jörg Rheinberger's developmental model of molecular genetics and illustrate how the stages he identifies - the direction of the field, institutional developments, and epistemological demarcations - were already central themes in the comparative practices underlying narratives of contingency in this early period.

Social commitment influences our behavior in various ways. Recent studies suggest that social commitment to other individuals or groups can increase dishonest behavior while feeling commitment to moral norms might decrease it. Here we show in a pre-registered series of 7 studies investigating the influence of social commitment on dishonest behavior by sampling 7566 participants across three countries (the UK, the US, and Mexico) that commitment to moral norms via honesty oaths might decrease dishonesty (OR = 0.

A discrete time-to-event model for the meta-analysis of full ROC curves.

Res Synth Methods

November 2024

Biostatistics and Medical Biometry, Medical School OWL, Bielefeld University, Bielefeld, Germany.

The development of new statistical models for the meta-analysis of diagnostic test accuracy studies is still an ongoing field of research, especially with respect to summary receiver operating characteristic (ROC) curves. In the recently published updated version of the "Cochrane Handbook for Systematic Reviews of Diagnostic Test Accuracy", the authors point to the challenges of this kind of meta-analysis and propose two approaches. However, both of them come with some disadvantages, such as the nonstraightforward choice of priors in Bayesian models or the requirement of a two-step approach where parameters are estimated for the individual studies, followed by summarizing the results.

How does plant chemodiversity evolve? Testing five hypotheses in one population genetic model.

New Phytol

February 2025

Faculty of Biology, Computational Biology, Bielefeld University, Universitätsstraße 25, 33615, Bielefeld, Germany.

Plant chemodiversity, the diversity of plant-specialized metabolites, is an important dimension of biodiversity. However, there are so far few mathematical models to test verbal hypotheses on how chemodiversity evolved. Here, we develop such a model to test predictions of five hypotheses: the 'fluctuating selection hypothesis', the 'dominance reversal hypothesis', the interaction diversity hypothesis, the synergy hypothesis, and the screening hypothesis.

Introduction: A modern approach to ensuring privacy when sharing datasets is the use of synthetic data generation methods, which often claim to outperform classic anonymization techniques in the trade-off between data utility and privacy. Recently, it was demonstrated that various deep learning-based approaches are able to generate useful synthesized datasets, often based on domain-specific analyses. However, evaluating the privacy implications of releasing synthetic data remains a challenging problem, especially when the goal is to conform with data protection guidelines.
