Secondary water pore formation for proton transport in a ClC exchanger revealed by an atomistic molecular dynamics simulation [PDF]

open access: yes, 2008
Several prokaryotic ClC proteins have been demonstrated to function as exchangers that transport both chloride ions and protons simultaneously in opposite directions.

Microfluidic systems for in situ formation of nylon 6,6 membranes.

open access: yes, 2006
A microfluidics based, localised formation of nylon 6,6 membranes has been undertaken. The study demonstrates the feasibility of maintaining stable aqueous/organic interfaces for xylene within simple linear flow channels. Glass fabricated structures were

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

open access: yesAdvanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

From venom peptides to neurotherapeutics: BmK defensins and short-chain peptides as modulators of ion channels

open access: yesFrontiers in Pharmacology
Scorpions, having inhabited the Earth long before the emergence of humans, represent an ancient lineage of arthropods. While often regarded with fear due to their potential to induce severe pain or fatal envenomation, scorpion venoms constitute complex ...

VIVID: A qPCR‐Based Platform for Sensitive and Quantitative In Vivo Tracking of Extracellular Vesicles

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces VIVID (Vesicle In Vivo Identification using DNA), a qPCR‐based platform that tracks PCR‐amplifiable DNA tags loaded in the EVs for accurate and quantifiable EV biodistribution in vivo. ABSTRACT Extracellular vesicles (EVs) represent promising carriers for nucleic acid therapeutics, offering advantages over synthetic nanoparticles ...

The Effect of BaCl2 on the Resting Membrane Potential of the Superior Flexor Muscle of Crayfish, Procambarus clarkii

open access: yesImpulse: The Premier Undergraduate Neuroscience Journal, 2022
Barium ions block potassium leak channels that contribute to the resting membrane potential in most animal cells (Armstrong and Taylor, 1980). Here we examine the impact of barium on the resting membrane potential of crayfish superficial flexor muscles ...

Bistable dynamics underlying excitability of ion homeostasis in neuron models

open access: yes, 2014
When neurons fire action potentials, dissipation of free energy is usually not directly considered, because the change in free energy is often negligible compared to the immense reservoir stored in neural transmembrane ion gradients and the long-term ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Development of chloride channel modulators

open access: yesKidney International, 1995
Chloride channels are ubiquitously distributed, biophysically varied and functionally diverse. Despite the known contribution of chloride channels to the physiology of various cell types and the pathology of several diseases, high affinity ligands are not available to study these channels.
