A new human autologous hepatocyte/macrophage co-culture system that mimics drug-induced liver injury-like inflammation.

The development of in vitro hepatocyte cell culture systems is crucial for investigating drug-induced liver injury (DILI). One prerequisite for monitoring DILI related immunologic reactions is the extension of primary human hepatocyte (PHH) cultures towards the inclusion of macrophages. Therefore, we developed and characterized an autologous co-culture system of PHH and primary human hepatic macrophages (hepM) (CoC1).

A spatiotemporal style transfer algorithm for dynamic visual stimulus generation.

Understanding how visual information is encoded in biological and artificial systems often requires the generation of appropriate stimuli to test specific hypotheses, but available methods for video generation are scarce. Here we introduce the spatiotemporal style transfer (STST) algorithm, a dynamic visual stimulus generation framework that allows the manipulation and synthesis of video stimuli for vision research. We show how stimuli can be generated that match the low-level spatiotemporal features of their natural counterparts, but lack their high-level semantic features, providing a useful tool to study object recognition.

Persistent Epstein-Barr Virus Infection of Epithelial Cells Leads to APOBEC3C Expression and Induces Mitochondrial DNA Mutations.

Upon infection with the virus, cells increase the expression of cytidine deaminase APOBEC3 family genes. This leads to the accumulation of C-to-T mutations in the replicating viral genome and suppresses viral propagation. In contrast, herpesviruses, including Epstein-Barr virus (EBV), express genes that counteract APOBEC3 during lytic infection.

TSS-Captur: a user-friendly pipeline for characterizing unclassified RNA transcripts.

RNA-seq and its 5'-enrichment methods for prokaryotes have enabled the precise identification of transcription start sites (TSSs), improving gene expression analysis. Computational methods are applied to these data to identify TSSs and classify them based on proximal annotated genes. While some TSSs cannot be classified at all (orphan TSSs), other TSSs are found on the reverse strand of known genes (antisense TSSs) but are not associated with the direct transcription of any known gene.

Intramolecular feedback regulation of the LRRK2 Roc G domain by a LRRK2 kinase-dependent mechanism.

The Parkinson's disease (PD)-linked protein Leucine-Rich Repeat Kinase 2 (LRRK2) consists of seven domains, including a kinase and a Roc G domain. Despite the availability of several high-resolution structures, the dynamic regulation of its unique intramolecular domain stack is nevertheless still not well understood. By in-depth biochemical analysis, assessing the Michaelis-Menten kinetics of the Roc G domain, we have confirmed that LRRK2 has, similar to other Roco protein family members, a K value of LRRK2 that lies within the range of the physiological GTP concentrations within the cell.

Discarded sequencing reads uncover natural variation in pest resistance in .

Understanding the genomic basis of natural variation in plant pest resistance is an important goal in plant science, but it usually requires large and labor-intensive phenotyping experiments. Here, we explored the possibility that non-target reads from plant DNA sequencing can serve as phenotyping proxies for addressing such questions. We used data from a whole-genome and -epigenome sequencing study of 207 natural lines of field pennycress () that were grown in a common environment and spontaneously colonized by aphids, mildew, and other microbes.

Cretaceous spreite-dominated ichnoassemblages in Antarctica.

This study investigates ichnoassemblages characterized by spreite trace fossils from the Upper Cretaceous Snow Hill Island Formation on Vega Island, Antarctica. The succession reveals alternating heterolithic beds of sandy siltstones to very fine- to fine-grained sandstones, suggestive of a deltaic depositional setting influenced by fluctuating energy conditions. The dominance of spreite structures, such as Paradictyodora antarctica and Euflabella, suggests the prevalence of a colonization window for deposit- or detritus-feeding activity.

A Defined Diet Combined with Sonicated Inoculum Provides a High Incidence, Moderate Severity Form of Experimental Autoimmune Encephalomyelitis (EAE).

Background: Myelin oligodendrocyte glycoprotein 35-55 (MOG)-peptide induced experimental autoimmune encephalomyelitis (EAE) is a model for inflammation of the brain and spinal cord. However, its severity and incidence vary within and between laboratories. Severe scores can lead to premature termination and are both unnecessary for readouts and detrimental to animal welfare.

Interactions of transcranial magnetic stimulation with brain oscillations: a narrative review.

Brain responses to transcranial magnetic stimulation (TMS) can be recorded with electroencephalography (EEG) and comprise TMS-evoked potentials and TMS-induced oscillations. Repetitive TMS may entrain endogenous brain oscillations. In turn, ongoing brain oscillations prior to the TMS pulse can influence the effects of the TMS pulse.

Effect of antiepileptic drug monotherapy on endogenous sex hormonal profile in men and women with epilepsy.

Objective: To assess the alterations of endogenous sex hormone profiles in patients with epilepsy (PWE) on different antiepileptic drug (AED) monotherapies compared to healthy controls and drug naïve PWE (DNPWE).

Methods: Four databases MEDLINE, EMBASE, SCOPUS, and CENTRAL were searched for analytical observational/intervention studies on the assessment of endogenous sex hormones in PWE compared to healthy controls and DNPWE. Two researchers reviewed the title/abstract, and full-text articles for the selection of the studies independently.

Integrating Biological Early Warning Systems with High-Resolution Online Chemical Monitoring in Wastewater Treatment Plants.

Detection of micropollutants (MPs) in wastewater effluents using traditional toxicity tests or chemical analysis with discrete samples is challenging due to concentration dynamics. This study evaluates a continuous monitoring approach for detecting MPs in wastewater effluents using a combination of biological early warning systems (BEWS). Three BEWS with , , and were operated in parallel in a full-scale municipal wastewater treatment plant.

Diagnostic Accuracy of Lung and Abdominal Ultrasound for Tuberculosis in a German Multicenter Cohort of Patients With Presumed Tuberculosis Disease.

Background: There is limited evidence on point-of-care ultrasound for tuberculosis (TB), but studies suggest high sensitivity, especially for lung ultrasound (LUS). However, insufficient data are available on specificity of the examination and its generalizability to a broader patient population.

Aims: Our study aimed to establish accuracy for lung, chest, and abdominal ultrasound, individually and in combination, for TB diagnosis.

The role of motivation in selection processes-comparing sports and business.

Talent identification and selection in sports pose significant challenges, necessitating a nuanced understanding of factors influencing athletes' elite-level potential. While physical and physiological aspects have conventionally played roles in the selection process, also other constructs of talent development have to be considered. Various talent models have included psychological aspects, especially motivation, as either moderators or catalysts.

Maintenance therapy with trofosfamide, idarubicin and etoposide in patients with rhabdomyosarcoma and other high-risk soft tissue sarcomas (CWS-2007-HR): a multicentre, open-label, randomised controlled phase 3 trial.

Background: Rhabdomyosarcoma and other soft tissue sarcomas (STS) with high-risk features are still associated with an unsatisfactory outcome. We evaluated the efficacy of oral maintenance therapy added at the end of standard therapy in patients with high-risk rhabdomyosarcoma and STS.

Methods: CWS-2007-HR was a multicentre, open-label, randomised controlled, phase 3 trial done at 87 centers in 5 countries.

Cognitive Impairment in Cerebral Amyloid Angiopathy: A Single-Center Prospective Cohort Study.

We sought to assess specific cognitive domains which are mainly affected among patients with CAA and to investigate probable associations with neuroimaging markers and Cerebrospinal Fluid (CSF) biomarkers. Thirty-five patients fulfilling the Boston Criteria v1.

Prenatal Maternal Psychological Stress (PMPS) and Its Effect on the Maternal and Neonatal Outcome: A Retrospective Cohort Study.

Background/objectives: Prenatal psychology studies show that stress, depression, and psychological stress during pregnancy can have a significant impact on maternal and fetal health and are highly prevalent. The aim of the study was to compare maternal and neonatal short-term outcomes in pregnant women* (the asterisk (*) is used at the appropriate places in this text to indicate that all genders are included) with a history of prenatal maternal psychological stress (PMPS) with those of pregnant women* not exposed to PMPS to determine differences and identify risk factors.

Methods: Statistical tests for differences and relative risks between the groups were carried out with the perinatal data of University Hospital Tübingen from 2022 using IBM SPSS.

DNA Damage and Inflammatory Response of p53 Null H358 Non-Small Cell Lung Cancer Cells to X-Ray Exposure Under Chronic Hypoxia.

Hypoxia-induced radioresistance limits therapeutic success in cancer. In addition, p53 mutations are widespread in tumors including non-small cell lung carcinomas (NSCLCs), and they might modify the radiation response of hypoxic tumor cells. We therefore analyzed the DNA damage and inflammatory response in chronically hypoxic (1% O, 48 h) p53 null H358 NSCLC cells after X-ray exposure.

MnCl(CNH): Insights into a Luminescent Transition Metal-Melem Complex.

In this work, the (MnCl(CNH) complex has been synthesized via solid-state reaction between manganese (II) chloride and melamine in the molar ratio of 1:2. A similar synthesis has been repeated with CoCl, and FeCl, resulting in two new metal-melam complexes (FeCl(CNH) and CoCl(CNH)). MnCl(CNH) crystallizes in the monoclinic crystal system with the space group 2/.

Self-Regulation in Preschool: Are Executive Function and Effortful Control Overlapping Constructs?

The concepts of executive function (EF) and effortful control (EC) are strikingly similar. EF originates from neurocognitive research and is described as an accumulation of cognitive processes that serve the goal-oriented self-regulation of an individual. EC originates from temperament research and is defined as the efficiency of executive attention, including the ability to inhibit a dominant response, activate a subdominant response, proceed in a planned manner, and recognize conflicts or errors.

Dietary fiber pectin alters the gut microbiota and diminishes the inflammatory immune responses in an experimental peach allergy mouse model.

Since therapeutic options are limited the utilization of prebiotics is suggested to prevent food allergies (FAs). Using an experimental peach allergy model we explored the effect of dietary fiber pectin, a high-methoxyl heteropolysaccharide, on the manifestation of FA. CBA/J mice were sensitized, subsequently orally boosted and provoked with peach peel extract.

Single-cell RNA-seq reveals as a prognostic biomarker in low-grade endometrial stromal sarcoma.

Background: Low-grade endometrial stromal sarcoma (LG-ESS) is a rare uterine malignancy characterized by its complex tumor microenvironment (TME) and high recurrence rates, posing challenges to accurate prognosis and effective treatment. Identifying prognostic biomarkers is essential for improving patient stratification and guiding therapeutic strategies.

Methods: Using single-cell transcriptome analysis combined with H&E and multiplex immunofluorescence staining, we identified a subpopulation of tumor cells in LG-ESS and further validated the association of this subpopulation and its characteristic genes with LG-ESS prognosis by molecular characterization and bulk transcriptome data.
