P1.005. Preliminary Pilot Study Cohort Results - Cost-Effective Surveillance Strategies and Prediction of Cancer Recurrence After Endoscopic Therapy for Barrett’s Esophagus (Endeavor)

Abstract Topic Esophageal Cancer: Barrett‘s Esophagus: High-Grade Dysplasia and Early Invasive Cancer Background In many European countries, esophageal adenocarcinoma (EAC) incidence is increasing [1]. Barrett’s esophagus(BE), strongly associated with EAC, can progress via dyspla...

P1.106. Proteomic Signatures of Chemoresistance in Oesophageal Adenocarcinoma Cell Models

Abstract Topic Esophageal Cancer: Molecular Biology/Pathology Background Oesophageal adenocarcinoma is a rapidly rising cancer with poor prognosis. Despite advances in surgery, chemotherapy, and targeted therapy, five-year survival remains below 20%. Treatment failure is largely...

AngleCam V2: Predicting leaf inclination angles across taxa from daytime and nighttime photos

Abstract Understanding how plants capture light and maintain their energy balance is crucial for predicting how ecosystems respond to environmental changes. By monitoring leaf inclination angle distributions (LIADs), we can gain insights into plant behaviour that directly influen...

Up and Downthe Hill-Plot: Hydrides of CeGe–Structureand Magnetism

Abstract The hydrogenation behavior of FeB type CeGe was investigated. Hydrogenation (deuteration) produces mixtures of two modifications, similar to hydrides of other FeB type phases LnTt (Ln = La, Ce, Nd; Tt = Si, Ge). P-CeGeD0.75(2) (Pnma, a = 8.1603(5) Å, b = 4.0938(3) Å, c =...

Some degrees of difference: impact of in vitro cultivation temperature on mesenchymal stromal cells from species with different body core temperatures

Abstract Background Multipotent mesenchymal stromal cells (MSC) are promising candidates for regenerative therapies in human and animal patients. However, limiting comparability between studies in different species, subtle differences between their MSC occur. Contributing to this...

The morpho-syntax of Standard Scottish English

Abstract With empirical research on Standard Scottish English showing a bias towards phonology, the aim of the current study is to contribute to the morpho-syntactic documentation of this variety. Relying on Standard Southern British English for comparison, we concentrate on four...

Subgroup variations in effectiveness of femoropopliteal sirolimus versus paclitaxel-coated balloon angioplasty: post hoc results of the randomised SIRONA trial

INTRODUCTION: The randomised SIRONA trial showed that sirolimus-coated balloon (SCB) angioplasty was non-inferior to paclitaxel-coated balloon angioplasty (PCB) regarding femoropopliteal primary patency. There was no difference in clinically driven target lesion revascularisation...

Longitudinal changes in gut microbiota across reproductive states in wild baboons

Background: In humans and other mammals, female reproduction is linked to extensive changes in physiology, immunity, hormones, and behavior. These changes likely shape, and may be shaped by, the composition of gut microbial communities. Characterizing the dynamics of gut microbia...

The Effects of Collecting Bovine Milk Samples Premilking and Postmilking on the Results of Bacteriologic Analysis and Somatic Cell Count

Milk sample collection before attaching the milking cluster for bacteriological and cytological examination is a standard clinical diagnostic procedure in dairy production. Collecting samples premilking can be difficult under certain field conditions. Therefore, we aimed to deter...

Reconciling nitrogen fertilization effects on soil nitrification with acidification

Nitrogen (N) fertilization supports nearly half of the global population but disrupts the N cycle. While N addition is assumed to stimulate soil nitrification by increasing substrate supply and nitrifier activity, it may also inhibit nitrification via soil acidification. Resolvin...

Holocene hydroclimatic variability and multi-frequency analyses at Lake Sidi Ali (Morocco)

Abstract. The North African desert margin is considered one of the most sensitive areas to future climate changes, yet the periodicities, coupling mechanisms and external forcing of Holocene environmental variability remain poorly understood. To investigate millennial- to centenn...

Robotic group formation with phosphorescent trails

<title>Abstract</title> Stigmergy is an alternative to direct communication if unavailable. We evaluate whether group formation tasks are possible for swarm robots using stigmergic communication. Our aim is to control the size of a group. We show this is possible in experiments u...

We Give a Shit: A Commentary on the Psychometric Properties of the Organizational Bullshit Perception Scale

Organizational bullshit refers to workplace communication with no regard for the truth. An important step toward the empirical study of this ubiquitous phenomenon was the development and validation of the organizational bullshit perception scale (OBPS; Ferreira et al., 2022). In...

Predict-then-optimise interchange control for rail logistics with combined passenger-freight chains

Interchange decisions at rail transfer stations directly affect end-to-end service reliability and cost-to-serve; yet, existing delay-management approaches either forecast delays without prescribing actions or optimise dispatch with coarse delay representations. We propose a pred...

Systemic influences on orthodontic tooth movement: mechanisms and clinical implications

Orthodontic tooth movement (OTM) is a complex biological process involving bone remodeling, which can be significantly affected by systemic diseases and systemic factors. This review comprehensively examines how systemic conditions such as diabetes mellitus, thyroid dysfunction,...

Bridging Nanoscopic Surface Heterogeneity and MacroscopicNucleation Rates: A Perspective on Probabilistic Approaches

Abstract Predicting the number of newly formed crystals and their spatial distribution on surfaces or within pore spaces matters across many fields, from structural biology to coupled fluid flow and reactive transport in porous media to atmospheric physics. Nucleation occurs at m...

From lab to table: promissory narratives and the future of protein production in response to global crises

Abstract. Promotional videos are a key site through which cellular agriculture (CellAg) companies present cultured meat as a response to food system and environmental crises. Yet research on promissory narratives around alternative proteins has focused mainly on textual and news...

One Health and antimicrobial stewardship: a call to multi-sectoral collaboration to prevent the emerging epidemic of antimicrobial resistance

A common misconception is that Antimicrobial resistance (AMR) stems solely from poor treatment management in hospitals and weak health systems. AMR is, however, driven by a multitude of factors, including environmental stressors such as contamination from industrial, agricultural...
