Application of gas chromatography-stable isotope mass spectrometry to determine the oxygen isotope ratio of water in concentrated fruit juice

Journal of Agriculture and Food Research
In this study, we developed a method to determine the authenticity of concentrated fruit juice using the δ18O ratio of water. We utilized the gas chromatography-isotope ratio mass spectrometry (GC-IRMS) technique along with the offline isotope exchange ...

Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

Advanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

Spatially Resolved Multiomics Reveals Metabolic Remodeling and Autophagy Activation in Adamantinomatous Craniopharyngiomas

Advanced Science, EarlyView.
Multiomics integration analysis reveals the “cystic fluid–tumor cell” metabolic coupling that mediates active choline/ethanolamine uptake of tumor cells from cystic fluid and PC/PE synthesis pathways reprogramming that mediating autophagy pathway activation within ACP. ABSTRACT Adamantinomatous craniopharyngioma (ACP), a benign yet highly recurrent and

Structure‐Guided Engineering of a Promiscuous O‐Methyltransferase for a SAM Regeneration Biocatalysis Platform of Methylated Pharmaceuticals

Advanced Science, EarlyView.
A substrate promiscuous and regioselective O‐methyltransferase, SmOMT, is functionally and structurally characterized. A double mutant, SmOMTE152A/I306A, exhibited enhanced catalytic activity. By coupling this mutant with a mutant halide methyltransferase, AtHMTV140T, for SAM regeneration, a superior artificial fusion enzyme, AtHMTV140T‐L95‐SmOMTE152A ...
