Statement Of Problem: The accuracy of intraoral scanners for implant-supported prostheses in edentulous jaws is unclear with limited clinical evidence.
Purpose: The purpose of this in vitro and in vivo study was to evaluate the accuracy of a novel 3-dimensionally (3D) printed custom resin scanning crossbar (3D-CRC) for digital scans of complete arch implants and to provide a clinical benchmark.
Material And Methods: Four implants were placed on a completely edentulous master model for in vitro scanning.
Efficient interfacial energy conversion and rapid charge transfer are crucial for application-oriented microbial electrochemical systems (MES) and depend on affordable high-performance anodes. Herein, hierarchically porous 3D anodes with controlled millimeter-scale macropores (1-2 mm) were fabricated via carbonization of phenolic foam embedded with expanded polystyrene (EPS) sacrificial templates. Optimizing EPS loading (4 wt%) and pore-sizes yielded anode L-4M, exhibiting appropriate hydrophilicity (contact angle: 60.

This study aims to investigate the correlation between magnetic resonance imaging (MRI) T1/T2 mapping sequences and biomarkers of collagen deposition and ongoing systemic inflammation, and to evaluate the potential of T1/T2 mapping as a non-invasive method for the accurate diagnosis of liver fibrosis.
Methods: A mouse model of carbon tetrachloride (CCl)-induced liver fibrosis was established and T1/T2 mapping were performed at different weeks of treatment.
The glymphatic system theory introduces a new perspective on fluid flow and homeostasis in the brain. Here, cerebrospinal fluid and interstitial fluid (CSF-ISF) moves from the perivascular spaces (PVS) of arteries to those of veins for drainage. Aquaporin-4 (AQP4) plays a crucial role in driving fluid within the PVS.

In this work, a novel "Y"-shaped MnIII5DyIII3 complex, [MnIII5DyIII3(NO)(OCH)(L)(L')(tea)(teaH)]OH·3CHOH·2HO (1, HL = 2-methoxy-6-[()-(1-1,2,4-triazol-3-ylimino)methyl]phenol, Htea = triethanolamine and HL' = 2-hydroxy-3-methoxybenzaldehyde), was obtained through the reaction of the HL ligand, teaH, Dy(NO)·6HO and MnCl·4HO in CHOH and DMF. Structural analysis revealed that the coordination geometry of Dy1 in 1 is muffin-like (MFF-9, ), while the geometries of Dy2 and Dy3 fall among spherical capped square antiprism-like (CSAPR-9, ), spherical tricapped trigonal prism-like (TCTPR-9, ) and muffin-like (MFF-9, ).

The results demonstrated that CM-extracted LYPLs exhibited the lowest oxidation levels, while EE-extracted LYPLs contained the highest polyunsaturated fatty acids (PUFAs) content. EH extraction was more effective for monounsaturated fatty acids (MUFAs) in LYPLs but was less effective for polar lipids.

This study aims to analyze the interrelationships and potential mechanisms between social support, sense of security, family cultural capital and academic self-efficacy.
Methods: A multivariate moderated mediation model was constructed by surveying 1,119 college students using the Social Support Scale, the Sense of Security Scale, the Academic Self-efficacy Scale, and the Family Cultural Capital Scale.
The radiotherapy-induced release of DNA fragments can stimulate the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (cGAS-STING) pathway to prime antitumor immunity, but this pathway is expected to be less potent because of the inefficient cytosolic delivery of negatively charged DNA fragments. In this study, manganese-coordinated chitosan (CS-Mn) microparticles with selective DNA-capturing capacity are concisely prepared via a coordination-directed one-pot synthesis process to potentiate the immunogenicity of radiotherapy. The obtained CS-Mn microparticles that undergo rapid disassembly under physiological conditions can selectively bind with DNA to form positively charged DNA-CS assemblies because of the strong electrostatic interaction between linear chitosan and DNA molecules.

The temperature capability of dielectric polymers is limited to below 200 °C, lagging behind requirements for high-power and harsh-condition electronics. Here we report a molecular topology design for dielectric polymers with mechanical bonds that overcomes this obstacle, where cyclic polyethers are threaded onto the axles of various polyimides.

Flexible conductive materials with mechanical properties similar to those of biological tissues have been shown to have better long-term biointegration and functionality than rigid conductive materials. In this study, liquid metal (LM)-based conductive polycaprolactone/gelatin/polypyrrole/LM (PCL/Gel/PPy/LM, PGPL) NGC was combined with exogenous ES to repair PNI.

Stable luminescent diradicals, characterized by the presence of two unpaired electrons, exhibit unique photophysical properties that are sensitive to external stimuli such as temperature, magnetic fields, and microwaves. This sensitivity allows the manipulation of their spin states and luminescence, setting them apart from traditional closed-shell luminescent molecules and luminescent monoradicals. As a result, luminescent diradicals are emerging as promising candidates for a variety of applications.

Macrocyclic structures are popular in supramolecular chemistry and have enjoyed considerable success as platforms for elaboration to container compounds and new materials. Host/guest studies in organic media have relied heavily on structures derived from crown ethers, calixarenes, cucurbiturils, resorcinarenes and pillararenes over the past decades. More recently, their water-soluble versions have been developed for potential applications in biology.

Free from strategically important elements such as lithium, nickel, cobalt, and copper, potassium-ion batteries (PIBs) are heralded as promising low-cost and sustainable electrochemical energy storage systems that complement the existing lithium-ion batteries (LIBs). However, the reported electrochemical performance of PIBs is still suboptimal, especially under practically relevant battery manufacturing conditions. The primary challenge stems from the lack of electrolytes capable of concurrently supporting both the low-voltage anode and high-voltage cathode with satisfactory Coulombic efficiency (CE) and cycling stability.
