This subset of the repository contains the video data of the study. This includes mp4-files that show stained proteins in an apical to basal direction. It further contains the Fiji macro used for generating mp4-files from tif-files that can be found in the image data subset of this collection.
Vorschlag für ein gemeinsames Metadatenschema für die Sammlungen der Philipps-Universität Marburg
(Philipps-Universität Marburg, Stabsstelle Forschungsdatenmanagement) Maul, Alexander
Die Philipps-Universität Marburg entwickelt derzeit ein Konzept zur digitalen Präsentation ihrer wissenschaftlichen Sammlungen. Hierbei verfolgt ein im Rahmen der Landesinitiative HeFDI vom Hessischen Ministerium für Wissenschaft und Forschung, Kunst und Kultur (HMWK) gefördertes Projekt den Auftrag, Datenbankmanagementsysteme zur Integration wissenschaftlicher Sammlungen anzu-passen. Neben der Konzeptionierung und Implementierung einer langfristig trag-fähigen Datenbank hat das Projekt die Pilotierung der Sammlungsdigitalisierung an der Philipps-Universität zur Aufgabe. Der Projektfortschritt wird über die Projektseite (https://uni-marburg.de/DFpFGf) dokumentiert.
Der Datensatz enthält einen Vorschlag für ein gemeinsames Metadatenschema für die Sammlungen der Philipps-Universität. Hierbei unterteilt sich das Modell in folgende Bereiche:
1. Automatische Administrationsfelder
2. Minimalerfassung
3. Empfohlene Erfassungsfelder
4. Zusätzliche Felder für Objekte aus sensiblen Kontexten
5. Akzession, Bilanzierung, Deakzession
6. Interne Dokumentation und Sammlungsmanagement
7. Individuelle sach- und fachspezifische Metadatenfelder
Der Vorschlag gibt den Bearbeitungsstand im November 2024 wieder. Er ist ausdrücklich als Vorschlag konzipiert, auf dessen Grundlage weitere Absprachen erfolgen sollten.

This subset of the repository contains the analytical data generated in the study. This includes data of the transcript expression analysis, multiplex immunoassays, enzyme-linked immunosorbent assays, image analyses, and measurement of transepithelial resistance. Furthermore, the validation of the multiplex immunoassays with purified proteins and sera is included.

Abstract:
The randomized study aimed to evaluate the comparability of in situ (iS) and in vitro (iV) study protocols regarding remineralization of artificial enamel lesions. Two toothpastes (group A: 1450 ppm sodium fluoride, group B: placebo 0 ppm F-), were investigated. IV, a pH-cycling model with toothpaste slurry treatment was applied for 10d. IS, remineralization was performed in 9 participants wearing splints with embedded enamel samples for 10 and 21d, randomly allocated to groups A and B. Samples were scanned by X-ray micro-computed tomography (μCT) and grayscale value line profiles corresponding to mineral density (rel.ΔZ) were analyzed.
T-Test for dependent and independent data and analysis of variance (ANOVA) were used for further analyses (α = 0.05).
Rel.ΔZ of fluoride treated samples (A) were iV = 40.2%, iS 10d = 11.5% and iS 21d = 46.1% (p > 0.05). Rel.ΔZ of placebo treated samples (B) were: iV = − 6.2%, iS 10d = 25.2% and iS 21d = 11.0% (p > 0.05). Remineralization potential of both toothpastes was significantly different regarding iV (p < 0.001) and iS after 21d (p = 0.034), while in case of iS 10d no significant difference was detected (p = 0.4). Despite different study protocols the μCT results after remineralization were comparable between iV and iS.
The results suggest that selected studies can be carried out in faster, simplified iV studies using pH-cycling instead of iS studies.
