Untargeted metabolomics and functional analyses reveal that the secondary metabolite quinic acid associates with Angelica sinensis flowering.

Flowering is a critical step in the plant life cycle. Angelica sinensis (Oliv.) Diels is a medicinal crop whose root is a well-known herbal medicine used in Asia.

Trends in Heavy Metal Pollution in Agricultural Land Soils of Tropical Islands in China (2000-2024): A Case Study on Hainan Island.

Heavy metal contamination in agricultural soils has garnered increasing attention, yet research on the spatiotemporal trends of heavy metal pollution in tropical regions with multiple annual crop harvests remains limited. This study examines data from 41 studies published between 2000 and 2024, including 206 records from 4122 sampling points on Hainan Island in China, to investigate the spatial distribution and temporal trends of heavy metal pollution. The results reveal that the average concentrations of Cd, Pb, As, Cr, and Hg in surface soil samples from agricultural lands on Hainan Island are 0.

A feature fusion method based on radiomic features and revised deep features for improving tumor prediction in ultrasound images.

Background: Radiomic features and deep features are both vitally helpful for the accurate prediction of tumor information in breast ultrasound. However, whether integrating radiomic features and deep features can improve the prediction performance of tumor information is unclear.

Methods: A feature fusion method based on radiomic features and revised deep features was proposed to predict tumor information.

Evaluation of Siemens Atellica AMH assay and comparison with Roche, Beckman and Ansh Labs.

Background: Anti-Müllerian hormone (AMH) is an important marker for ovarian reserve and response to fertility treatments. However, interassay variability exists due to the lack of a standardized method. This study evaluates the performance of the new Siemens Healthineers Atellica IM AMH assay against established assays (Beckman DxI 600 Access, Roche cobas Elecsys® e801, and Ansh Labs AMH ELISA).

Surface fluorination mediated electro-oxidative degradation of HFPO-DA on boron-doped diamond electrode.

Heptafluoropropylene oxide dimer acid (HFPO-DA), as an alternative to perfluorooctanoic acid (PFOA), has been shown to pose similar environmental and health risks as other perfluorinated compounds. The electrochemical-based advanced oxidation processes are promising techniques for the treatment of perfluorinated compounds, and the boron-doped diamond (BDD) anode could degrade HFPO-DA under mild conditions. However, the roles of radicals in the degradation and how to overcome the steric hindrance of the -CF branch on the carboxyl group were not yet clear.
