Supercapacitive Carbon‐Coated δ‐MnO2 Nanosheets as a Solid‐Contact Material for Self‐Testing Potassium‐Ion Biosensors

Small, EarlyView.
A simple and energy‐efficient method was developed to synthesize carbon‐coated δ‐MnO2 nanosheets (δ‐MnO2@C). This multifunctional material serves as both a supercapacitor electrode and a solid‐contact for self‐testing K+‐ion biosensors. Compared to activated carbon, δ‐MnO2@C enhances Faradaic supercapacitive properties, improving the K+‐ion sensing ...

Conundrums of Localized Surface Plasmon Resonance Biosensors

Small, EarlyView.
Localized surface plasmon resonance (LSPR) biosensing faces fundamental conundrums arising from finite field decay lengths, environmental cross‐sensitivities, and batch variability. Competing surface, bulk, and electrostatic effects can induce red or blue spectral shifts, complicating quantification, reproducibility, and interpretation in complex or ...

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments

Journal of Fish Biology, EarlyView.
Abstract The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion‐poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO2 levels (hypoxia and hyperoxia), high PCO2 levels (hypercapnia), high ...

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

The Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

Electrodiffusion in cardiac intercalated disc nanostructures alters cell–cell action potential transmission via ephaptic coupling: A model study

The Journal of Physiology, EarlyView.
Abstract figure legend Ephaptic phenomena in a high‐resolution model of the cardiac intercalated disc. Meshed representation of a tortuous intercalated disc that was generated based on electron and super‐resolution microscopy data. Na+ channels (red) and gap junctions (green) are heterogeneously distributed, with additional regions of reduced ion ...

Intercalated disk structure, tissue heterogeneity and ion channel distribution modulate conduction and local calcium influx

The Journal of Physiology, EarlyView.
Abstract figure legend A, three‐dimensional representation of cardiac intercalated disk, reduced to a 100‐partition, computationally efficient network representation. B, ion dynamics within intercalated disk extracellular cleft space. C, rapid pacing leads to localized conduction block in tissue with regions of perturbed intercalated disk (ID ...

Sarcolemmal and mitochondrial membrane potentials measured ex vivo and in vivo in the heart by pharmacokinetic modelling of [99mTc]sestamibi

The Journal of Physiology, EarlyView.
Abstract figure legend The pharmacokinetics of lipophilic cationic radiotracers such as [99mTc]sestamibi and [99mTc]tetrofosmin are dependent on the electrical potentials that determine their distribution across the sarcolemmal and mitochondrial membranes.

Efficacy of a K+ Channel Agonist, XEN1101, For Preserving Contractility in Mouse Models of Hypokalemic Periodic Paralysis

Muscle &Nerve, Volume 73, Issue 4, Page 668-674, April 2026.
Pretreatment with an agonist of Kv7 potassium channels (XEN1101) protects the soleus muscle from a loss of force during a 2 mM K+ challenge, in a mouse model of hypokalemic periodic paralysis. ABSTRACT Introduction/Aims Effective management remains lacking for recurrent episodes of acute weakness in hypokalemic periodic paralysis (HypoPP).

The plasticisation model of dye diffusion: Part 5

Coloration Technology, Volume 142, Issue 2, Page 296-326, April 2026.
Abstract The findings presented in the previous part of the paper (Part 4) of the re‐evaluation of previously published data reported for the temperature‐dependent diffusion of an organic acid within nylon 6 film, desorption of three acid dyes from dyed nylon 66 fabric, diffusion of an acid dye within nylon 6 monofilaments and adsorption of a sulphur ...
