Hydrogen isotope separation at exceptionally high temperature using an unsaturated organometallic complex.

A new approach for hydrogen isotope separation using an unsaturated organometallic complex was proposed. Adsorption measurements of [Mn(dppe)(CO)(N)](BArF) (Mn-dppe) (dppe = 1,2-bis(diphenylphosphino)ethane, BArF = B[CH(3,5-CF)]) using H and D revealed a significant difference in the adsorption enthalpy of H/D at much higher room temperatures than in previous studies, with D molecules being more strongly adsorbed on unsaturated metal sites. Mixed gas adsorption isotherms were calculated at each temperature using IAST, and it was predicted that D uptake was much larger than H uptake.

Decoding Brain Development and Aging: Pioneering Insights From MRI Techniques.

The aging process induces a variety of changes in the brain detectable by magnetic resonance imaging (MRI). These changes include alterations in brain volume, fluid-attenuated inversion recovery (FLAIR) white matter hyperintense lesions, and variations in tissue properties such as relaxivity, myelin, iron content, neurite density, and other microstructures. Each MRI technique offers unique insights into the structural and compositional changes occurring in the brain due to normal aging or neurodegenerative diseases.

Lung immune incompetency after mild peritoneal sepsis and its partial restoration by type 1 interferon: a mouse model study.

Background: Sepsis is commonly associated with acute respiratory distress syndrome (ARDS). Although the exaggerated inflammation may damage intact lung tissues, a percentage of patients with ARDS are reportedly immunocompromised, with worse outcomes. Herein, using a murine sepsis model, time-course immune reprogramming after sepsis was evaluated to explore whether the host is immunocompromised.

BCL11A +58/+55 enhancer-editing facilitates HSPC engraftment and HbF induction in rhesus macaques conditioned with a CD45 antibody-drug conjugate.

Editing the +58 region of the BCL11A erythroid enhancer has shown promise in treating β-globin disorders. To address variations in fetal hemoglobin (HbF) response, we investigated editing both +58 and +55 enhancers. Rhesus macaques transplanted with edited hematopoietic stem/progenitor cells (HSPCs) following busulfan conditioning exhibited durable, high-level (∼90%) editing frequencies post transplantation with sustained HbF reactivation over 4 years, without hematological perturbations.

Evaluating chemical effects on human neural cells through calcium imaging and deep learning.

The adsorption behaviors of H and CO molecules in crown-motif [PtAu(PPh)]-H[PMoO] (PtAu8-PMo12) solids were investigated by quick-scan X-ray absorption fine structure (QXAFS) measurements with a time resolution of 0.1 s. The electronic state of Pt in PtAu8-PMo12 was drastically changed by the adsorption of H and CO molecules because of the formation of Pt-H/Pt-CO interactions.

Prediction of Vancomycin-Associated Nephrotoxicity Based on the Area under the Concentration-Time Curve of Vancomycin: A Machine Learning Analysis.

Several machine learning models have been proposed to predict vancomycin (VCM)-associated nephrotoxicity; however, they have notable limitations. Specifically, they do not use the area under the concentration-time curve (AUC) as recommended in the latest guidelines and do not address imbalanced data. Thus, we aimed to develop a novel model for predicting VCM-associated nephrotoxicity while overcoming these limitations.

However, the lack of understanding of the active site prevents the realization of a high-performance electrocatalyst for the CORR.

Temporal changes over time in sputum rheological parameters after SARS-CoV-2 infection in two patients with chronic cough.

We report temporal changes in sputum rheological parameters after SARS-CoV-2 infection in two patients with chronic cough (71-year-old, male, sinobronchial syndrome; 80-year-old, female, cough variant asthma). Both patients complained of decreased cough-related quality of life and increased phlegm stickiness after infection. In parallel, their sputum showed decreases in linear viscoelastic region (LVR) parameters, such as viscoelastic modulus (G), elastic modulus (G'), and viscous modulus (G″), and increased tack (tan δ/G'; tan δ = G″/G') compared to pre-infection levels.

OpenMAP-T1: A Rapid Deep-Learning Approach to Parcellate 280 Anatomical Regions to Cover the Whole Brain.

This study introduces OpenMAP-T1, a deep-learning-based method for rapid and accurate whole-brain parcellation in T1- weighted brain MRI, which aims to overcome the limitations of conventional normalization-to-atlas-based approaches and multi-atlas label-fusion (MALF) techniques. Brain image parcellation is a fundamental process in neuroscientific and clinical research, enabling a detailed analysis of specific cerebral regions. Normalization-to-atlas-based methods have been employed for this task, but they face limitations due to variations in brain morphology, especially in pathological conditions.
