A single-phase epitaxially grown ferroelectric perovskite nitride.

The integration of ferroelectrics with semiconductors is crucial for developing functional devices, such as field-effect transistors, tunnel junctions, and nonvolatile memories. However, the synthesis of high-quality single-crystalline ferroelectric nitride perovskites has been limited, hindering a comprehensive understanding of their switching dynamics. Here we report the synthesis and characterizations of epitaxial single-phase ferroelectric cerium tantalum nitride (CeTaN) on both oxides and semiconductors.

The Application of Quantitative H-NMR for the Determination of Melatonin and Vitamin B6 in Commercial Melatonin Products.

Melatonin supplements have been widely used to improve sleep quality and overcome sleep disorders, with melatonin and vitamin B6 serving as the primary active ingredients. This study developed a novel analytical method for the simultaneous quantification of melatonin and vitamin B6 using H-NMR spectroscopy. The characteristic signals of melatonin and vitamin B6 hydrochloride at δ 7.

Spon2 knockdown suppresses the phenotype of house dust mite-induced allergic asthma in mice and cells.

Allergic asthma is a chronic inflammatory disease of the airways. The objective of this study was to identify potential therapeutic targets for allergic asthma through RNA sequencing (RNA-seq) and experimental analyses. Allergic asthma models, both in cells and mice, were induced using house dust mite (HDM) treatment.

Metagenomic insights into the microbial communities and functional traits of hot springs in Guizhou Province, China.

Introduction: Hot springs were previously believed to be uninhabitable due to their hostile nature. However, recent studies have determined that hot springs not only have a rich microbiota but are also involved in various biogeochemical processes and possess unique characteristics that can be utilized for several biotechnological applications. This study aimed to determine the bacterial taxonomic diversity and functional profiles of 11 hot springs in the Guizhou Province, China.

Coupling of glucose metabolism with mitophagy via O-GlcNAcylation of PINK1.

Mitophagy is a selective form of autophagy for the clearance of damaged and dysfunctional mitochondria via the autophagy-lysosome pathway. As mitochondria are the most important metabolic organelles, the process of mitophagy is tightly regulated by glucose metabolism. At present, it is known that glucose is required for the mitophagy process, while the underlying mechanisms remain to be further elucidated.
