Prognostic relevance of CT-defined body composition in patients with acute bleeding undergoing endovascular embolization.

Objectives: Body composition assessment includes the parameter skeletal muscle mass, subcutaneous and visceral adipose tissue (SAT and VAT). The purpose of this study was to elucidate associations of body composition parameters with mortality in patients with acute bleeding undergoing transarterial embolization (TAE).

Methods: A mixed cohort of patients from 2018 to 2022 with acute bleeding requiring treatment with a TAE was retrospectively evaluated.

Full Quantum Dynamics Study for H Atom Scattering from Graphen.

This study deals with the understanding of hydrogen atom scattering from graphene, a process critical for exploring C-H bond formation and energy transfer during atom surface collision. In our previous work [Shi, L.; 2023, 159, 194102], starting from a cell with 24 carbon atoms treated periodically, we have achieved quantum dynamics (QD) simulations with a reduced-dimensional model (15D) and a simulation in full dimensionality (75D).

Predicting the risk of intensive care unit admission in patients with COVID-19 presenting in the emergency room: Development and evaluation of the CROSS score.

Background: Existing risk evaluation tools underperform in predicting intensive care unit (ICU) admission for patients with the Coronavirus Disease 2019 (COVID-19). This study aimed to develop and evaluate an accurate and calculator-free clinical tool for predicting ICU admission at emergency room (ER) presentation.

Methods: Data from patients with COVID-19 in a nationwide German cohort (March 2020-January 2023) were analyzed.

Diagnostic Accuracy and Reliability of CT-based Node-RADS for Esophageal Cancer.

Background/aim: The recently published Node-Reporting and Data System (Node-RADS) can aid the characterization of lymph nodes in cross-sectional imaging. This study investigated the Node-RADS system in computed tomography (CT) to characterize lymph nodes in esophageal cancer.

Patients And Methods: Overall, 126 patients (15 female, 11.

Light-Activatable Ubiquitin for Studying Linkage-Specific Ubiquitin Chain Formation Kinetics.

Ubiquitination is a dynamic post-translational modification governing protein abundance, function, and localization in eukaryotes. The Ubiquitin protein is conjugated to lysine residues of target proteins, but can also repeatedly be ubiquitinated itself, giving rise to a complex code of ubiquitin chains with different linkage types. To enable studying the cellular dynamics of linkage-specific ubiquitination, light-activatable polyubiquitin chain formation is reported here.
