Prädiktoren für eine behandlungsbedürftige Koronarstenose nach einer ventrikulären Arrhythmie bei Patienten mit Implantierbarem Kardioverter-Defibrillator (ICD)
(2025-08-01)In dieser retrospektiven Studie wurden 183 ICD-Patienten untersucht, die nach einer ventrikulären Arrhythmie (VA) eine Koronarangiographie erhielten. Ziel war es, Prädiktoren für das Vorliegen einer behandlungsbedürftigen ... -
Hierarchical hub-filament structures of molecular gas: star formation and cluster evolution
(2025-07-30)The first part of this thesis presents a multi-scale investigation of hub–filament structures, analyzing their morphology, kinematics, and evolution from dense core (~1000 AU) to clump (~1 pc), molecular cloud (~10–100 ... -
Deep Representation Learning for Financial Document Analytics
(2025-07-30)In this thesis, we leverage machine learning (ML) methods primarily based on deep neural networks to drastically reduce the manual work of financial analysts, investors, auditors, and other stakeholders by automating key ... -
Development and Application of efficient automated Workflows for Quantum Chemistry-based property calculations
(2025-07-30)This thesis deals with the application and development of Quantum Chemistry (QC) workflows with the aim of calculating molecular properties under standard conditions and comparing them to observables from experiments. ... -
Entwicklung zweier methodischer Ansätze zur Charakterisierung von Emissionen aus Tierhaltungsanlagen mit der MALDI-TOF Massenspektrometrie und der NIR-Spektroskopie
(2025-07-30)Diese Arbeit präsentiert zwei innovative Analyseansätze zur Charakterisierung von Bioaerosol-Emissionen aus Tierhaltungsanlagen: die <strong>Nahinfrarot-Spektroskopie (NIRS)</strong> und die <strong>MALDI-TOF Massenspekt ... -
Neuroprotective Role and Immunomodulatory Effects of Sialylation
(2025-07-29)Sialic acids are terminal sugars on the cellular glycocalyx, crucial for modulating immune responses in the sialylated central nervous system. Sialylation acts as an inhibitory checkpoint, regulating inflammation and tissue ... -
Force system of 3D-printed orthodontic aligners made of shape memory polymers: An in vitro study
(2024-06-10)This study aimed to report forces and moments delivered by 3D-printed aligners. Tera Harz TC-85 resin and Zendura FLX (ZF) thermoformed sheets (0.76 mm) were used. Rectangular strip specimens (50 × 10 × 0.6 mm) were produced ... -
Effect of the Height of a 3D-Printed Model on the Force Transmission and Thickness of Thermoformed Orthodontic Aligners
(2024-06-20)This research aims to investigate the influence of model height employed in the deep drawing of orthodontic aligner sheets on force transmission and aligner thickness. Forty aligner sheets (Zendura FLX) were thermoformed ... -
Retro Mode Imaging for Detection and Quantification of Sub-RPE Drusen and Subretinal Drusenoid Deposits in Age-Related Macular Degeneration
(2024-07-15)<strong>Background:</strong> Drusen and drusenoid deposits are a hallmark of age-related macular degeneration (AMD). Nowadays, a multimodal retinal imaging approach enables the detection of these deposits. However, ... -
Diagnoses and Treatment Recommendations—Interrater Reliability of Uroflowmetry in People with Multiple Sclerosis
(2024-07-18)Background: Uroflowmetry (UF) is an established procedure in urology and is recommended before further investigations of neurogenic lower urinary tract dysfunction (NLUTD). Some authors even consider using UF instead of ... -
The Phenotypic Correlates and Genetic Basis of the Central Neuroendocrine System
(2025-07-29)The hypothalamus is considered the body’s principal center for maintaining homeostasis and orchestrating the secretion of multiple hormones. The pineal gland closely interacts with the hypothalamus and forms an essential ... -

Extracellular matrix substrates differentially influence enteric glial cell homeostasis and immune reactivity
(2024-07-25)<strong>Introduction:</strong> Enteric glial cells are important players in the control of motility, intestinal barrier integrity and inflammation. During inflammation, they switch into a reactive phenotype enabling them ... -
In vitro extracellular replication of Wolbachia endobacteria
(2024-07-18)Obligate intracellular endobacteria of the genus <em>Wolbachia</em> are widespread in arthropods and several filarial nematodes. Control programs for vector-borne diseases (dengue, Zika, malaria) and anti-filarial therapy ... -
Bidirectional Effect of Long-Term Δ9‑Tetrahydrocannabinol Treatment on mTOR Activity and Metabolome
(2024-08-14)Brain aging is associated with cognitive decline, reduced synaptic plasticity, and altered metabolism. The activity of mechanistic target of rapamycin (mTOR) has a major impact on aging by regulating cellular metabolism. ... -
