Affinity descriptor of metal catalysts: concept, measurement and application of oxygen affinity in the catalytic transformation of oxygenates.

Multiple oxygenate groups in biomass-based feedstocks are open to multiple catalytic pathways and products, typically resulting in low selectivity for the desired products. In this context, strategies for rational catalyst design are critical to obtain high selectivity for the desired products in biomass upgrading. The Sabatier principle provides a conceptual framework for designing optimal catalysts by following the volcanic relationship between catalyst activity for a reaction and the binding strength of a substrate on a catalyst.

Speechreading Ability Affects Mandarin Tone Perception in Young Adults With Prelingual Hearing Impairment in China.

Purpose: This cross-sectional study explored how the speechreading ability of adults with hearing impairment (HI) in China would affect their perception of the four Mandarin Chinese lexical tones: high (Tone 1), rising (Tone 2), falling-rising (Tone 3), and falling (Tone 4). We predicted that higher speechreading ability would result in better tone performance and that accuracy would vary among individual tones.

Method: A total of 136 young adults with HI (ages 18-25 years) in China participated in the study and completed Chinese speechreading and tone awareness tests.

Methods: This retrospective study includes 30 eyes from 30 iERM patients who had surgery, with a three-month follow-up period. In addition, 28 eyes from 28 healthy individuals served as a control group.

Novel Meningoencephalomyelitis Associated With Vimentin IgG Autoantibodies.

Importance: Autoantibodies targeting astrocytes, such as those against glial fibrillary acidic protein (GFAP) or aquaporin protein 4, are crucial diagnostic markers for autoimmune astrocytopathy among central nervous system (CNS) autoimmune disorders. However, diagnosis remains challenging for patients lacking specific autoantibodies.

Objective: To characterize a syndrome of unknown meningoencephalomyelitis associated with an astrocytic autoantibody.

Research on the infiltration law and enhancing application of dust suppressants in powder materials.

Dust emissions from open-pit mining pose a significant threat to environmental safety and human health. Currently, the range of dust suppressants used in coal mining is limited, often failing to account for their suitability across various stockpiles. This oversight results in poor infiltration after application, leading to insufficient crust formation and reduced durability.

Background: Anterior glenoid bone defects significantly influence surgical outcomes in shoulder instability cases. Various measurement methods based on 3-dimensional computed tomography (3D-CT) have been developed. Recently, the simple linear formula method, which establishes a correlation between glenoid height and width, has emerged as a promising technique.

Impact of human intervention and predator-prey dynamics on ecosystem virus transmission.

Humans and predators occupy dominant positions in ecosystems and are generally believed to play a decisive role in maintaining ecosystem stability, particularly in the context of virus transmission. However, this may not always be the case. By establishing some ecosystem virus transmission models that cover both human perspectives and predators, we have drawn the following conclusions: (1) Controlling vaccination activities from the human perspective can potentially lower the transmission rate and improve herd immunity, thereby indirectly protecting unvaccinated risk groups.

Paternal Cyanidin-3-O-Glucoside Diet Improved High-Fat, High-Fructose Diet-Induced Intergenerational Inheritance in Male Offspring's Susceptibility to High-Fat Diet-Induced Testicular and Sperm Damage.

High-fructose and high-fat diet (HFHFD) has been associated with impaired spermatogenesis, leading to decreased sperm quality and increased male infertility, with similar effects observed in offspring. Cyanidin-3-O-glucoside (C3G), a recognized food antioxidant, has shown promise in protecting in male reproduction and modulating epigenetic modifications. However, its potential role in ameliorating intergenerational inheritance induced by HFHFD remains underexplored.

Smartphone-based non-invasive detection of salivary uric acid based on the fluorescence quenching of gleditsia sinensis carbon dots.

A smartphone-based non-invasive method was developed for salivary uric acid detection using Gleditsia Sinensis carbon dots (GS-CDs). The GS-CDs synthesized by the one-pot hydrothermal method emitted blue fluorescence at a maximum excitation wavelength of 350 nm and had good fluorescence stability in the presence of different ions, while showing selectivity to uric acid solution. The ability of uric acid (UA) to quench the fluorescent substances present in the GS-CDs, was confirmed through HPLC-FLD and LC-MS, FTIR and XPS.

MAO-B-triggered reaction for an optical triple-signal assay and AND logic gate application based on PEI-functionalized silver nanoparticles.

A novel analytical method was designed and developed that exhibited ultraviolet-visible (UV-Vis), fluorescence (FL), and resonance Rayleigh scattering (RRS) signals for straightforward and comprehensive determination of monoamine oxidase B (MAO-B) using polyethylenimine-functionalized silver nanoparticles (PEI-Ag NPs). Through a facile one-step experiment, and NaOH assisted, in an aqueous solution of 100 ℃ for 40 min PEI reacted with AgNO to generate PEI-Ag NPs with a yellow color and weak blue fluorescence. Interestingly, phenylacetaldehyde (PAA), a specific product of MAO-B, causes significant enhancement of the three optical signals of UV-Vis, FL, and RRS.

Shallow groundwater near a deep-well CO storage site-15 years of stable water quality for agricultural use.

Injecting CO into deep geological formations can be an effective carbon removal and storage technology to mitigate global climate change. Interaction of injected CO with rock formations changes pH and hydrochemistry within the deep injection zone (> 800 m depth). However, cap rocks and multiple tight aquitards typically act as barriers to protect the shallow aquifer from changes in the injection zone.

Synergistic effect of canine FGF-21 combined with insulin in the treatment of canine diabetes.

Previous studies have shown that FGF-21 can ameliorate hyperglycemia and improve the level of oxidative stress in vivo in diabetic mice. The hypoglycemic effect is safe and lasting, but it takes a longer time to exert its effect. Insulin treatment of canine diabetes takes effect quickly; however, its action time is short, and it is prone to cause hypoglycemia.
