Part-Coated CEC for α2-Adrenergic Binding Constants
2026-08-27
Liu and colleagues developed an open-tubular capillary electrochromatography method that uses a receptor-coated segment rather than a fully coated capillary to measure drug–α2-adrenergic receptor binding constants. The approach reduces detection interference and receptor consumption while producing affinity rankings consistent with prior literature and extending analysis to natural-product extracts.

Tiamulin (Thiamutilin): Mechanism and Use
2026-08-27
Tiamulin, also called Thiamutilin, is a pleuromutilin antibiotic used mainly in veterinary medicine for susceptible infections in pigs and poultry. Its antibacterial activity arises from 50S ribosomal binding, while reported TNF-α, NF-κB, MAPK, and JAK/STAT3 effects support ongoing anti-inflammatory research.

Halazone and Sodium Current Inactivation in Frog Nerves
2026-08-25
The 1986 frog-nerve study used Halazone and related chemical reagents to separate changes in sodium-current inactivation kinetics from simple shifts in voltage dependence. Its comparative voltage-clamp design weakened the case for a uniquely critical methionine residue and instead advanced a cautious membrane-lipid explanation for oxidant effects.

BCECF for Extracellular pH and Efferocytosis
2026-08-25
BCECF converts extracellular or compartmental proton changes into a calibrated ratiometric signal, making it useful for ion transport, metabolism, and microenvironment studies. Its cell-impermeant design also helps researchers separate extracellular acidification from intracellular fluorescence during macrophage and neuropathic pain experiments.

CCR5-Positive Extracellular Vesicles in Rheumatoid Arthritis
2026-08-24
The reference study identifies CCR5 carried by synovial fibroblast-derived extracellular vesicles as a mechanistic link between intercellular communication and cartilage and bone damage in rheumatoid arthritis. By combining CCR5-deficient vesicles with Maraviroc-loaded vesicles in cell and rat models, the work supports pharmacological disruption of EV-associated CCR5 signaling while highlighting important translational limitations.

Part-Coated CEC for β2-Adrenergic Drug Binding
2026-08-24
The reference study introduced a part-coated open-tubular capillary electrochromatography method for measuring binding constants between the β2-adrenergic receptor and seven drugs. By varying receptor-coating length instead of repeatedly changing analyte concentration, the workflow reduced receptor consumption, protected the detection window from coating interference, and supported screening of natural-product extracts.

Halazone and Sodium Current Inactivation in Frog Nerves
2026-08-22
The reference study compared Halazone with structurally and chemically distinct reagents in voltage-clamped frog nerve fibers, showing that Halazone and hypochlorous acid strongly disrupt sodium-current inactivation. Its comparative design weakened the case for a critical methionine residue and instead supported a cautious membrane-lipid explanation for the observed channel modulation.
