CT material decomposition with contrast agents: Single or multiple spectral photon-counting CT scans? A simulation study.

Purpose: With the widespread introduction of dual energy computed tomography (DECT), applications utilizing the spectral information to perform material decomposition became available. Among these, a popular application is to decompose contrast-enhanced CT images into virtual non-contrast (VNC) or virtual non-iodine images and into iodine maps. In 2021, photon-counting CT (PCCT) was introduced, which is another spectral CT modality.

Dual pathway inhibition in patients with peripheral artery disease in Germany.

: Dual-pathway inhibition (DPI) with aspirin and rivaroxaban exhibited a net clinical benefit for patients with cardiovascular disease in the randomized COMPASS trial. The non-observational, international XATOA registry showed that the COMPASS results can be reproduced in clinical practice in patients with coronary artery disease (CAD) and peripheral artery disease (PAD). Here we report patient characteristics and clinical outcomes for the subgroup of German PAD patients of the XATOA registry and compare them to COMPASS PAD patients.

Patterns of Cerebellar-Cortical Structural Covariance Mirror Anatomical Connectivity of Sensorimotor and Cognitive Networks.

The cortex and cerebellum are densely connected through reciprocal input/output projections that form segregated circuits. These circuits are shown to differentially connect anterior lobules of the cerebellum to sensorimotor regions, and lobules Crus I and II to prefrontal regions. This differential connectivity pattern leads to the hypothesis that individual differences in structure should be related, especially for connected regions.

Sustainable upgrading of biomass: a thermodynamic approach to fine-tuning product selectivity for glycerol oxidation.

Calculated thermodynamic properties for the electrochemical glycerol oxidation at different temperatures and potentials indicate that external applied bias has a more significant influence on reaction selectivity than temperature.

Design and characterization of a micro RNA-200c detecting Broccoli fluorescent light-up aptamer.

In the last decade the important role of small non-coding RNAs such as micro RNAs (miRs) in gene regulation in healthy and disease states became more and more evident. The miR-200-family of miRs has been shown to play a critical role in many diseases such as cancer and neurodegenerative disorders and could be potentially important for diagnosis and treatment. However, the size of miRs of about ~21-23nt provide challenges for their investigation.

Potential Adaptive Introgression From Dogs in Iberian Grey Wolves (Canis lupus).

Invading species along with increased anthropogenization may lead to hybridization events between wild species and closely related domesticates. As a consequence, wild species may carry introgressed alleles from domestic species, which is generally assumed to yield adverse effects in wild populations. The opposite evolutionary consequence, adaptive introgression, where introgressed genes are positively selected in the wild species, is possible but has rarely been documented.

Quantum state processing through controllable synthetic temporal photonic lattices.

Quantum walks on photonic platforms represent a physics-rich framework for quantum measurements, simulations and universal computing. Dynamic reconfigurability of photonic circuitry is key to controlling the walk and retrieving its full operation potential. Universal quantum processing schemes based on time-bin encoding in gated fibre loops have been proposed but not demonstrated yet, mainly due to gate inefficiencies.

Unveiling the enzymatic pathway of UMG-SP2 urethanase: insights into polyurethane degradation at the atomic level.

The recently discovered metagenomic urethanases UMG-SP1, UMG-SP2, and UMG-SP3 have emerged as promising tools to establish a bio-based recycling approach for polyurethane (PU) waste. These enzymes are capable of hydrolyzing urethane bonds in low molecular weight dicarbamates as well as in thermoplastic PU and the amide bond in polyamide employing a Ser-Ser -Lys triad for catalysis, similar to members of the amidase signature protein superfamily. Understanding the catalytic mechanism of these urethanases is crucial for enhancing their enzymatic activity and improving PU bio-recycling processes.

Fabrication of Cu@Ag core-shell/nafion/polyalizarin: Applications to simultaneous electrocatalytic oxidation and reduction of nitrite in water samples.

In this study, a Cu@Ag core-shell was synthesized using a co-precipitation method. To create a new electrochemical sensor, a Cu@Ag core-shell with conductive polymers such as polyalizarin yellow R (PA) and Nafion (Nf) was immobilized on the surface of a glassy carbon electrode (Cu@Ag-Nf/PA/GCE). X-ray diffraction analysis (XRD), energy dispersive X-ray analysis (EDX), transmission electron microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FTIR) techniques were employed to characterize the Cu@Ag-Nf/PA/GCE.

The association between underlying conditions, risk factors, risk markers, and post-COVID conditions ≥6 months after COVID-19: A systematic review.

Introduction: While various demographic factors and underlying medical conditions are associated with the development of post-COVID conditions within a month after SARS-CoV-2 infection, less is known about factors associated with post-COVID symptoms that persist for 6 months or more. The aim of this review was to determine the association between underlying conditions, other risk factors, health behaviors, and the presence of symptoms ≥6 months after COVID-19.

Methods: Studies reporting on post-COVID symptoms were searched in databases, including Medline, EMBASE, Global Health, PsycInfo, Scopus, CINAHL, Proquest, and WHO COVID-19 literature, from the beginning of the pandemic until November 2022.

Linking Functional Traits To Trophic Roles In Scavenger Assemblages.

Scavenging is a widespread feeding strategy involving a diversity of taxa from different trophic levels, from apex predators to obligate scavengers. Scavenger species play a crucial role in ecosystem functioning by removing carcasses, recycling nutrients and preventing disease spread. Understanding the trophic roles of scavenger species can help identify specialized species with unique roles and species that may be more vulnerable to ecological changes.
