Intermittent Fasting Restores Cardiac Lipid Homeostasis in Diabetic Cardiomyopathy in Association With Akkermansia Muciniphila and 1‐methyl‐L‐histidine

Advanced Science, EarlyView.
Intermittent fasting reshapes the gut microbiota in diabetic cardiomyopathy, restoring Akkermansia muciniphila and the microbiota‐associated metabolite 1‐methyl‐L‐histidine. This shift is linked to improved cardiac lipid homeostasis, reduced lipid peroxidation, and attenuated myocardial injury, highlighting a gut microbiota–metabolite–lipid axis in ...

The factors and protocols that influence, accuracy, precision and uncertainty of accurate mass measurements by FT-ICR ms to validate the assignment of elemental composition

, 2009
The need for very accurate mass measurements of compounds is becoming more demanding with the expansion of the number of compounds in need of correct identification and with the limits of elemental analysis; a fast, robust analytical solution is sought ...

Ti‐Doping Activates Adjacent Zr Sites in Bimetallic MOFs for Cooperative Phospholipid Removals in Human Biomonitoring

Advanced Science, EarlyView.
Ti‐doped Zr/Ti bimetallic MOFs activate neighboring Zr sites to selectively capture phospholipids from serum through cooperative interactions. In nontargeted screening, the material minimizes matrix interference, expands detectable feature coverage, and enables broad recovery of diverse chemical hazards, providing a powerful cleanup strategy for LC ...

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform

Advanced Science, EarlyView.
Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

Isomeric Ag14 Nanoclusters With Distinct Photophysical and Nanomechanical Properties

Advanced Science, EarlyView.
Ligand‐shell isomerism in atomically precise Ag14 nanoclusters is demonstrated to regulate core distortion, photoluminescence, and mechanical properties. Subtle changes in phosphine ligand arrangement drive a pronounced emission shift from green to red and alter crystal rigidity, revealing a direct structure‐property correlation that offers new design ...

Radical‐Mediated In Situ Fluorescence Dye Deposition: A Simple Interfacial Signal Amplification Reaction for Ultrasensitive Immunoassay on Barcode Beads

Advanced Science, EarlyView.
A radical‐mediated in situ fluorescence dye deposition (RIFD) reaction containing merely three elements of beads, dyes, and radicals is discovered for the first time, and its underlying mechanism is elucidated. This simple RIFD enables the interfacial and ultrafast deposition of free dyes onto barcode beads, serving as a powerful signal amplification ...

Gut Microbial Release of Ferulic Acid From Germinated Quinoa Alleviates Obesity‐Associated Cognitive Impairment by Activating Hippocampal Mitophagy Associated with PINK1/Parkin Pathway

Advanced Science, EarlyView.
Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

Cancer‐Associated BCL‐2 Mutants Reveal Mechanisms Towards Venetoclax Resistance

Advanced Science, EarlyView.
Venetoclax (VEN) resistance in chronic lymphocytic leukemia arises from diverse BCL2 mutations. We map mechanisms contributing to VEN resistance across common BCL‐2 variants. G101V and D103Y reduce drug binding and increase sequestration of pro‐apoptotic proteins. V156D blocks VEN allosterically.
