Breaking symmetry for better catalysis: insights into single-atom catalyst design.

Breaking structural symmetry has emerged as a powerful strategy for fine-tuning the electronic structure of catalytic sites, thereby significantly enhancing the electrocatalytic performance of single-atom catalysts (SACs). The inherent symmetric electron density in conventional SACs, such as M-N configurations, often leads to suboptimal adsorption and activation of reaction intermediates, limiting their catalytic efficiency. By disrupting this symmetry of SACs, the electronic distribution around the active center can be modulated, thereby improving both the selectivity and adsorption strength for key intermediates.

Chronic unpredictable mild stress induces anxiety-like behavior in female C57BL/6N mice, accompanied by alterations in inflammation and the kynurenine pathway of tryptophan metabolism.

Chronic stress can impact brain function through various mechanisms, contributing to the development of anxiety disorders. Chronic unpredictable mild stress (CUMS) is a well-established model for studying the effects of chronic stress. This study assessed the impacts of different durations of CUMS on anxiety-like behavior, inflammation, and tryptophan metabolism in female C57BL/6N mice.

SOX9 Overexpression Ameliorates Metabolic Dysfunction-associated Steatohepatitis Through Activation of the AMPK Pathway.

Background And Aims: The transcription factor sex-determining region Y-related high-mobility group-box gene 9 (SOX9) plays a critical role in organ development. Although SOX9 has been implicated in regulating lipid metabolism , its specific role in metabolic dysfunction-associated steatohepatitis (MASH) remains poorly understood. This study aimed to investigate the role of SOX9 in MASH pathogenesis and explored the underlying mechanisms.

The Theory and Practice of Sensory Evaluation of Vinegar: A Case of Italian Traditional Balsamic Vinegar.

Sensory analysis is a very powerful and useful tool that is used for a variety of foods. But for vinegar, the relevant sensory evaluation system is not satisfactory since there are still some issues, such as the tendency for score conservatism, descriptor redundancy, sensory fatigue and other cognitive issues. In this review, the theory of the sensory evaluation of vinegar is first introduced, and then the application of sensory evaluation is summarized for vinegar, especially for Italian Traditional Balsamic Vinegar.

Rapeseed and Palm Oils Can Improve the Growth, Muscle Texture, Fatty Acids and Volatiles of Marine Teleost Golden Pompano Fed Low Fish Oil Diets.

This study evaluated the effects of different lipid sources-fish oil (FO), soybean oil, rapeseed oil, and palm oil-on the growth and muscle quality of golden pompano () cultured in offshore cages for 10 weeks. Three diets (D1-D3) were formulated: D1 used only fish oil, D2 blended fish, rapeseed oil, and palm oil, and D3 combined fish and soybean oils. Fish in the D1 group showed the highest weight gain, specific growth rate, and muscle protein content, significantly outperforming D3.
