National analysis of health-related social needs among adult injury survivors.

Background: Despite advances in trauma care, the effects of social determinants of health continue to be a barrier to optimal health outcomes. Health-related social needs (HRSNs), now the basis of a Centers for Medicare and Medicaid Services national screening program, may contribute to poor health outcomes, inequities, and low-value care, but the impact of HRSNs among injured patients remains poorly understood at the national level.

Methods: Using data from the nationally representative 2021 Medical Expenditure Panel Survey, injured patients were matched with uninjured controls via coarsened exact matching on age and sex.

Water Disinfection with Dual-Wavelength (222 + 275 nm) Ultraviolet Radiations: Microbial Inactivation and Reactivation.

Emerging mercury-free ultraviolet (UV) sources, such as krypton chloride excimer (KrCl*) lamps and UV light emitting diodes (UV-LEDs), emit diverse wavelengths with distinct inactivation mechanisms. The combined application has the potential to improve disinfection effectiveness through synergism. In this study, a mini-fluidic photoreaction system equipped with a KrCl* lamp (222 nm) and a strip of UV-LEDs (275 nm) was developed, which could individually/simultaneously deliver accurate UV radiation(s) at 222 nm (0.

Immobile Integrin Signaling Transit and Relay Nodes Organize Mechanosignaling through Force-Dependent Phosphorylation in Focal Adhesions.

Transmembrane signaling receptors, such as integrins, organize as nanoclusters that provide several advantages, including increasing avidity, sensitivity (increasing the signal-to-noise ratio), and robustness (signaling threshold) of the signal in contrast to signaling by single receptors. Furthermore, compared to large micron-sized clusters, nanoclusters offer the advantage of rapid turnover for the disassembly of the signal. However, whether nanoclusters function as signaling hubs remains poorly understood.

Electron temperature measurement from neutral atomic tungsten emission line ratio.

A method to determine electron temperature within a plasma by the spectral analysis of atomic tungsten emission has been explored. The technique was applied to a post-discharge region immediately following a high voltage nanosecond pulsed discharge in air with tungsten electrodes. Atomic tungsten lines are readily observed in the weak emission spectrum within the post-discharge region for many microseconds.

Synergy of Hydrophilic Properties and Antibacterial Inhibition in Polyvinyl Alcohol Nanofibrous Mats Loaded With Croton Bonplandianum Baill Leaf Extract.

The antibacterial nanofibrous mat is crucial in biomedicine as it enhances infection control, expedites wound healing, and mitigates health hazards by decreasing antibiotic usage. A novel synergistic antibacterial and hydrophilic nanofibrous mat successfully fabricated by solution electrospinning from polyvinyl alcohol (PVA) incorporated Croton bonplandianum Baill (CBB) leaves extract. Antioxidant-enriched leaf extract of the CBB plant was integrated with PVA in varying proportions of 30% (CBB-30), 40% (CBB-40), and 50% (CBB-50) to manufacture antibacterial nanofibrous mat.

Molecular Drillers for 2 nm Resolution Nanochannel Perforation of 2D Nanoplates.

Perpendicular nanochannel creation of two-dimensional (2D) nanostructures requires highly controlled anisotropic drilling processes of the entire structure via void formation. However, chemical approaches for the creation of porosity and defects of 2D nanostructures have been challenging due to the strong basal plane chemical stability and the use of harsh reactants, tending to give randomly corroded 2D structures. In this study, we introduce Lewis acid-base conjugates (LABCs) as molecular drillers with attenuated chemical reactivity which results in the well-defined perpendicular nanochannel formation of 2D TiS nanoplates.

A cooperative model for metallocene catalyst activation by methylaluminoxane.

Activation of rac-MeSi(η-Ind)ZrMe (SBIZrMe) and sheet models for MAO, (MeAlO)(MeAl) (6,4), (MeAlO)(MeAl) (7,5), and (MeAlO)(MeAl) (26,9) was studied DFT. These activators can reversibly form an outer-sphere ion-pair (OSIP) [SBIZrMeAlMe] [(MeAlO)(MeAl)Me] 3 ([,] = [7,4]and [26,8]) or a contact ion-pair (CIP) SBIZrMe-μ-Me-6,4 (2b) from SBIZrMe. Dissociation of MeAl from 3 to form CIP SBIZrMe-μ-Me-, (2) is generally unfavourable but reversible in toluene continuum.

Strategy for Fabricating Degradable Low-Surface-Energy Cross-Linked Networks with Excellent Anti-Fouling Properties.

Marine biofouling negatively impacts marine industries and ship navigation. However, current coatings are based on a single antifouling mechanism, which is insufficient to cope with the complex and ever-changing marine environment. Herein, multifunctional antifouling coatings were developed using a material system containing perfluoropolyether and caprolactone chains.

Nano Acacetin Mitigates Intestinal Mucosal Injury in Sepsis Rats by Protecting Mitochondrial Function and Regulating TRX1 to Inhibit the NLRP3 Pyroptosis Pathway.

Background: Acacetin (AC) is a flavonoid compound with antiperoxidant, anti-inflammatory, and antiplasmodial activity. However, the solubility of AC is poor and nano acacetin (Nano AC) was synthesized. The intestinal mucosal barrier is impaired in sepsis rats, and the protective effects and mechanism of AC and Nano AC on the intestinal mucosal barrier are unclear.

Rational design of a series of non-centrosymmetric antiperovskite and double antiperovskite borate fluorides.

Non-centrosymmetric (NCS) compounds can exhibit many symmetry-dependent functional properties, yet their rational structure design remains a great challenge. Herein, a strategy to introduce F-centered octahedra to construct a perovskite-type framework filled by π-conjugated [BO] dimers is proposed to obtain NCS compounds. The first examples of antiperovskite or double antiperovskite borate fluorides, [(M/Ba)Ca]F[BO] (M = K, Rb) and [CsBaCa]F[BO], have been successfully designed and synthesized.

Specific inhibition of fibroblast growth factor receptor 1 signaling by a DNA aptamer.

Impaired fibroblast growth factor receptor (FGFR) signaling is associated with many human conditions, including growth disorders, degenerative diseases, and cancer. Current FGFR therapeutics are based on chemical inhibitors of FGFR tyrosine kinase activity (TKIs). However, FGFR TKIs are limited in their target specificity as they generally inhibit all FGFRs and other receptor tyrosine kinases.

uORF-targeting steric block antisense oligonucleotides do not reproducibly increase RNASEH1 expression.

Upstream open reading frames (uORFs) are -regulatory motifs that are predicted to occur in the 5' UTRs of the majority of human protein-coding transcripts and are typically associated with translational repression of the downstream primary open reading frame (pORF). Interference with uORF activity provides a potential mechanism for targeted upregulation of the expression of specific transcripts. It was previously reported that steric block antisense oligonucleotides (ASOs) can bind to and mask uORF start codons to inhibit translation initiation, and thereby disrupt uORF-mediated gene regulation.

Construction and high-throughput screening of gradient nanowire coatings on titanium surface towards ameliorated osseointegration.

Surface nano-modification has emerged as an effective strategy to enhance osseointegration of titanium (Ti) implants. Despite its promise, rational optimization of surface nanomorphology for ameliorated osseointegration remains a significant challenge. Our research pioneering developed a one-step alkali etching technique to produce a gradient nanowire coating with continuously varied dimensions on Ti surfaces, which was subsequently served as a versatile platform for high-throughput screening of optimal dimensions to enhance osseointegration.

Magnetic field-induced synergistic therapy of cancer using magnetoplasmonic nanoplatform.

Combining photothermal and chemotherapy using single nanoplatform is an emerging direction in cancer nanomedicine. Herein, a magnetic field (MF) induced combination of chemo/photothermal therapy is demonstrated using FeO@mSiO@Au core@shell@satellites nanoparticles (NPs) loaded with chemotherapeutic drug doxorubicin (DOX), both and An application of an external MF to the NPs dispersion causes magnetophoretic movement and aggregation of the NPs. While the synthesized NPs only slightly absorb light at ∼800 nm, their aggregation results in a significant near infrared (NIR) absorption associated with plasmon resonance coupling between the Au satellites in the NPs aggregates.
