Impact of opioid abuse on oral health: a retrospective cohort study.
Front Oral Health
February 2025
Department of Conservative Dentistry and Periodontology, University Hospital Regensburg, Regensburg, Germany.
Objectives: Opioid use has significantly increased in Germany in recent years. This study aimed to evaluate and compare the oral health, dental hygiene, self-perceived pain, and functional limitations of opioid-addicted patients with a healthy control group.
Materials And Methods: 50 opioid-addicted patients (OAP) attending substitution treatment at the Centre for Addiction Medicine of the Department of Psychiatry and Psychotherapy at the University of Regensburg were enrolled and interviewed about their drug use history.
Highly Accelerated Three-Dimensional Free-Breathing Cardiac T2 Mapping with Modified Low-Rank Modeling of Local K-Space Neighborhoods.
Annu Int Conf IEEE Eng Med Biol Soc
July 2024
Three-dimensional (3D) cardiac magnetic resonance T2 mapping has been proven beneficial for the diagnosis of myocardial edema. However, the time-consuming nature of cardiac quantitative imaging (e.g.

Linear vibronic coupling (LVC) models have proven to be effective in describing coupled excited-state potential energy surfaces of rigid molecules. However, obtaining the LVC parameters in molecules with many degrees of freedom and a large number of, possibly (near-)degenerate, electronic states can be challenging. In this paper, we discuss how the linear intra- and interstate couplings can be computed correctly using a numerical differentiation scheme, requiring a phase correction and sufficient numerical precision in the involved electronic structure calculations.

Background: Endometrial cancer (EC) is one of the most common gynecological malignancies and the second most common gynecological malignancy cause of death in women. Heterogeneous tissues with different grades of complexity and different diffusion properties characterize the EC. Several diffusion magnetic resonance imaging (DMRI) protocols have been used to perform a non-invasive and global evaluation of EC for diagnostic and prognostic purposes.

Institut Néel, Université Grenoble Alpes, CNRS, Grenoble INP, 38000 Grenoble, France.
We study spontaneous photon decay into multiple photons triggered by strong nonlinearities in an experimental simulator of a bosonic quantum impurity model. Previously, spectroscopic signatures of photon conversion were reported and evidenced as resonances in the many-body spectrum of these systems. Here, we report on the observation of multimode fluorescence of a small Josephson junction embedded in a high impedance superconducting transmission line.
