CPR related injuries of the chest wall: direct and indirect fractures.

Eur J Trauma Emerg Surg

January 2025

Department of Trauma and Orthopedic Surgery, University Hospital Erlangen, Friedrich-Alexander University Erlangen-Nürnberg (FAU), Erlangen, Germany.

Background: Rib and sternum fractures are common injuries associated with cardiopulmonary resuscitation (CPR). The fracture mechanism is either direct by application of force on sternum and anterior ribs or indirect by bending through compression of the thorax. The aim of this study was to determine morphologies of rib fractures after CPR and to reevaluate prior findings on fracture localisation, type and degree of dislocation.

Whole examination AI estimation of fetal biometrics from 20-week ultrasound scans.

NPJ Digit Med

January 2025

School of Biomedical Engineering and Imaging Sciences, Faculty of Life Sciences and Medicine, King's College London, London, UK.

The current approach to fetal anomaly screening is based on biometric measurements derived from individually selected ultrasound images. In this paper, we introduce a paradigm shift that attains human-level performance in biometric measurement by aggregating automatically extracted biometrics from every frame across an entire scan, with no need for operator intervention. We use a neural network to classify each frame of an ultrasound video recording.

Mechanistic basis of temperature adaptation in microtubule dynamics across frog species.

Curr Biol

January 2025

Max Planck Institute for Infection Biology, Virchowweg 12, 10117 Berlin, Germany; Marine Biological Laboratory, 7 Mbl St., Woods Hole, MA 02543, USA; Berliner Hochschule für Technik, Luxemburger Straße 10, 13353 Berlin, Germany. Electronic address:

Cellular processes are remarkably effective across diverse temperature ranges, even with highly conserved proteins. In the context of the microtubule cytoskeleton, which is critically involved in a wide range of cellular activities, this is particularly striking, as tubulin is one of the most conserved proteins while microtubule dynamic instability is highly temperature sensitive. Here, we leverage the diversity of natural tubulin variants from three closely related frog species that live at different temperatures.

Exudate management is essential for creating a moist wound environment that promotes optimal healing, especially in highly exuding wounds, where choosing an appropriate wound dressing to handle high volumes of exudate is a key part of the wound management strategy. Superabsorbent wound dressings (SWDs) have been designed to absorb and retain large amounts of exudate. Thus, they are advocated for management of wounds with moderate-to-high levels of exudate to reduce the risk of leakage and damage to the periwound skin.

Multiparametric MRI is a promising technique for noninvasive structural and functional imaging of the kidneys that is gaining increasing importance in clinical research. Still, there are no standardized recommendations for analyzing the acquired images and there is a need to further evaluate the accuracy and repeatability of currently recommended MRI parameters. The aim of the study was to evaluate the test-retest repeatability of functional renal MRI parameters using different image analysis strategies.

Deciphering the Energy Transfer Mechanism Across Metal Halide Perovskite-Phthalocyanine Interfaces.

Adv Sci (Weinh)

January 2025

Institute of Molecular Science, University of Valencia, c/Catedrático José Beltrán Martínez 2, Paterna, 46980, Valencia, Spain.

Energy transfer processes in nanohybrids are at the focal point of conceptualizing, designing, and realizing novel energy-harvesting systems featuring nanocrystals that absorb photons and transfer their energy unidirectionally to surface-immobilized functional dyes. Importantly, the functionality of these dyes defines the ultimate application. Herein, CsPbBr perovskite nanocrystals (NCs) are interfaced with zinc phthalocyanine (ZnPc) dyes featuring carboxylic acid.

Purpose: Fuchs endothelial corneal dystrophy (FECD) displays a higher incidence in females than in males, yet the underlying mechanism remains unclear. This study aimed to elucidate sex-dependent differential gene expressions in corneal endothelial cells (CECs) from healthy non-FECD individuals and from patients with FECD.

Methods: RNA-Seq data from CECs of non-FECD subjects (3 males, 4 females) and FECD subjects (5 males, 5 females) were analyzed to identify differentially expressed genes (DEGs) between the sexes.

The naturally occurring mutation E484D in the spike (S) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can render viral entry ACE2 independent and imdevimab resistant. Here, we investigated whether the cellular proteins ASGR1, DC-SIGN, and TMEM106B, which interact with the viral S protein, can contribute to these processes. Employing S protein-pseudotyped particles, we found that expression of ASGR1 or DC-SIGN jointly with TMEM106B allowed for robust entry of mutant E484D into otherwise non-susceptible cells, while this effect was not observed upon separate expression of the single proteins and upon infection with SARS-CoV-2 wild type (WT).

Bottom-up syntheses of carbon nanodots (CND) using solvothermal treatment of citric acid are known to afford nanometer-sized, amorphous polycitric acid-based materials. The addition of suitable co-reactants in the form of in-situ synthesized N-hetero-π-conjugated chromophores facilitates hereby the overall functionalization. Our incentive was to design a CND model that features phenazine (P-CND) - a well-known N-hetero-π-conjugated chromophore - to investigate the influence of the CND matrix on its redox chemistry as well as photochemistry.

Automated Lesion and Feature Extraction Pipeline for Brain MRIs with Interpretability.

Neuroinformatics

January 2025

Department of Radiology and Biomedical Imaging, University of California, San Francisco, San Francisco, CA, USA.

This paper introduces the Automated Lesion and Feature Extraction (ALFE) pipeline, an open-source, Python-based pipeline that consumes MR images of the brain and produces anatomical segmentations, lesion segmentations, and human-interpretable imaging features describing the lesions in the brain. ALFE pipeline is modeled after the neuroradiology workflow and generates features that can be used by physicians for quantitative analysis of clinical brain MRIs and for machine learning applications. The pipeline uses a decoupled design which allows the user to customize the image processing, image registrations, and AI segmentation tools without the need to change the business logic of the pipeline.

Balancing Activity and Stability through Compositional Engineering of Ternary PtNi-Au Alloy ORR Catalysts.

ACS Catal

January 2025

Department of Surface and Plasma Science, Faculty of Mathematics and Physics, Charles University, V Holešovičkách 2, 180 00 Prague 8, Czech Republic.

Achieving the optimal balance between cost-efficiency and stability of oxygen reduction reaction (ORR) catalysts is currently among the key research focuses aiming at reaching a broader implementation of proton-exchange membrane fuel cells (PEMFCs). To address this challenge, we combine two well-established strategies to enhance both activity and stability of platinum-based ORR catalysts. Specifically, we prepare ternary PtNi-Au alloys, where each alloying element plays a distinct role: Ni reduces costs and boosts ORR activity, while Au enhances stability.
