Dual‐Spectrum Fluorescence Quenching of Aggregation‐Induced Emission Nanoparticles for Dual‐Signal Lateral Flow Immunoassay of Danofloxacin in Meat Samples

Food Frontiers, Volume 7, Issue 6, November 2026.
ABSTRACT The conventional gold nanoparticle‐based lateral flow immunoassay (AuNPs‐LFIA) is hampered by single colorimetric signal readout and insufficient sensitivity, restricting its broad application in trace detection for food safety. Herein, an AuNPs‐triggered dual‐spectrum fluorescence quenching LFIA (DSFQ‐LFIA) was constructed for colorimetric ...

Tyramine modified alginates via periodate oxidation for peroxidase induced hydrogel formation and immobilization

, 2015
Phenol and amino groups were introduced into alginate to different degrees via oxidation with 2.5, 5, 10, 15 and 20 mol% of periodate and reductive amination by tyramine.

Characterization of the tyramine-producing pathway in Sporolactobacillus sp. P3J [PDF]

, 2011
A sporulated lactic acid bacterium (LAB) isolated from cider must was shown to harbour the tdc gene encoding tyrosine decarboxylase. The isolate belonged to the Sporolactobacillus genus and may correspond to a novel species.

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, Volume 49, Issue 11, Page 8306-8321, November 2026.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

A Quorum-Sensing Inhibitor Strain of Vibrio alginolyticus Blocks Qs-Controlled Phenotypes in Chromobacterium violaceum and Pseudomonas aeruginosa

Marine Drugs, 2019
The cell density-dependent mechanism, quorum sensing (QS), regulates the expression of virulence factors. Its inhibition has been proposed as a promising new strategy to prevent bacterial pathogenicity.

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

Advanced Science, Volume 13, Issue 57, 14 October 2026.
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 ...

Identifying a Csmd3+ Microglial Subpopulation that Drives Cold‐to‐Hot Transition and Immune‐Cure in Glioblastoma

Advanced Science, Volume 13, Issue 57, 14 October 2026.
The study establishes an immune‐cure (ICu) mouse model based on a TMEMed G422TN‐GBM system that faithfully recapitulates human TMEMed GBM. scRNA‐seq analysis reveals a Csmd3+ microglial subset with innate immune memory (IIM) potential that potently suppresses GBM growth, drives a TME cold‐to‐hot transition, and induces 100% ICu in long‐term survival ...

Biomimetic Scaffold‐Based 3D Models for Decoding Cancer Biology and Advancing Therapy

Advanced Science, Volume 13, Issue 58, 19 October 2026.
A timeline of the research history of 3D biomimetic scaffold materials and platforms. With advances in biomimetic materials and 3D scaffold technologies, their functional scope has expanded from mimicking basic physical and biochemical properties to increasingly replicating complex pathophysiological processes.

Beyond the Monolayer: Leveraging 3D Culture Systems to Decode Mechanisms of Drug Resistance and Therapeutic Vulnerabilities in Colorectal Cancer

Cancer Medicine, Volume 15, Issue 10, October 2026.
ABSTRACT Two‐dimensional (2D) monolayer cultures remain the workhorse of colorectal cancer (CRC) research and high‐throughput screening (HTS), yet they poorly recapitulate tissue architecture, extracellular matrix (ECM) cues, metabolic gradients, and multicellular heterogeneity that govern drug response in vivo. Over the past decade, three‐dimensional (

The Responsiveness of Tyramine Receptors in Caenorhabditis elegans when Matured without Monoamines

Using exogenous tyramine, behavior of four different mutant c. elegans was observed. These mutants include a wild type, triple monoamine knockout, a triple monoamine knockout containing a tyramine receptor knockout, and a tyramine receptor knockout ...
