Simultaneous Multi‐Analyte Detection of Viruses in Livestock Using a Multi‐Channel Magnetoelastic Sensor

Advanced Sensor Research, Volume 5, Issue 4, April 2026.
This study presents a portable, smartphone‐linked multi‐channel magnetoelastic sensor for the simultaneous detection of three airborne livestock viruses (H1N1, CSFV, FMDV). The multi‐channel sensor demonstrates linear, virus‐specific frequency shifts over its detection range, and the accuracy of this device is comparable with that of vector network ...

Split-dose Irradiation of Escherichia coli in the Absence and Presence of Mercaptoethylamine [PDF]

Journal of General Microbiology, 1969
SUMMARY: A single dose of γ-radiation to Escherichia coli b gave a semi-logarithmic dose-response curve. A second irradiation 3, 6, or 18 hr after a priming dose of 8 krad showed that the cells had become more radio-sensitive during the incubation between irradiations.

Nanoscale Mapping of the Subcellular Glycosylation Landscape

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Thiazolidine‐Grafted Zeolite Imidazolate Frameworks: A Cysteine‐Derived Route to Improved Metal Loading and Tune the CO2 Hydrogenation Efficiency

ChemSusChem, Volume 19, Issue 1, January 2026.
Covalent grafting of S‐containing ligands onto a zeolitic imidazolate framework (ZIF) forms thiazolidine groups that bind noble metal ions, enhancing metal capture. The highly porous ZIF structure supports controlled growth of metal nanoparticles, while the specific interactions between the thiazolidine groups and metal atoms enable high metal loading ...

Recent Advances in Enhancing the Stability of CsPbI3 Perovskite Quantum Dots for Light‐Emitting Diodes

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT CsPbI3 quantum dots (QDs) have attracted considerable attention as promising candidates for light‐emitting diode (LED) applications. However, their intrinsic tendency to undergo a spontaneous phase transition to a nonperovskite structure significantly hampers their practical deployment. Considerable efforts have been devoted to stabilizing the

2‐Mercaptoethylamine, a competitive inhibitor of spermidine synthase in mammalian cells [PDF]

FEBS Letters, 1988
Spermidine synthase from rat ventral prostate was inhibited by 2‐mercaptoethylamine (MEA). Inhibition of spermidine synthase by MEA was competitive with respect to one of the substrates putrescine, but not competitive with respect to the other substrate decarboxylated S‐adenosylmethionine.

Integration of Colorimetric Sensing Dyes and Multi‐Substrate Arrays for Food Quality and Safety Monitoring: Design, Optimization, and Analysis

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 1, January 2026.
ABSTRACT As food safety issues gain increasing attention, the need for rapid, accurate, and low‐cost detection techniques becomes essential. Colorimetric sensors, known for their rapid response, high sensitivity, low cost, and readily observable results, are playing an increasingly important role in food quality inspection. This review article provides

Some Central Nervous System Actions of Beta-Mercaptoethylamine

Experimental Biology and Medicine, 1966
Summary1. MEA synergizes with pentyl-enetetrazole to produce death in mice when it is injected simultaneously with it, or at 15, 30, 60, or 120 minutes preceding it. Thus, MEA has a stimulant action which comes on rapidly after intraperitoneal injection and endures for at least 2 hours. 2.

Continuous‐Wave (CW) Photo‐CIDNP NMR Spectroscopy: A Tutorial

Magnetic Resonance in Chemistry, Volume 63, Issue 12, Page 1020-1034, December 2025.
ABSTRACT Photo‐chemically induced dynamic nuclear polarisation (photo‐CIDNP) is a nuclear spin‐selective magnetic resonance phenomenon that has traditionally been used to mechanistically study chemical reactions involving the (transient) formation of radical molecular species, extract EPR observables of short‐lived radicals, probe biomolecular ...
