Fluorescence Sensing of Anions Like Adenosine 5ʹ‐Triphosphate With pH‐Gated Porous Dye‐Loaded Cerasomes

open access: yesSmall, EarlyView.
The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

Bioelectronic Wearable Sensors Produced by Computerized Embroidery Using a Dual Thread Approach

open access: yesSmall, EarlyView.
A dual‐thread embroidered SmartBra integrates silver‐plated and conductive‐polymer (PECOTEX) threads to enable simultaneous cardiac monitoring and open‐circuit potentiometric sensing of potassium and sodium in a breast milk substitute. The wearable platform is fabricated using computerized embroidery, offering a scalable, proof‐of‐concept route toward ...

Epidemiological distribution of MRI‐based presumptive imaging diagnoses in a large general population of cats with suspected epileptic seizures

open access: yesVeterinary Record, EarlyView.
Abstract Background The reported prevalence of feline idiopathic epilepsy (IE) and presumptive imaging diagnoses based on magnetic resonance imaging (MRI) varies depending on factors such as differences between primary care versus referral study populations.

Non‐canonical PKG1 regulation in cardiovascular health and disease

open access: yesBritish Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Cancer pain: current practice and emerging targets

open access: yesBritish Journal of Pharmacology, EarlyView.
Cancer pain (CP) arises from a complex interplay between the tumour and its microenvironment. Many patients experience a mixed pain phenotype that encompasses nociceptive, neuropathic and neuroinflammatory mechanisms, and vary across tumour type and disease stage. Despite decades of intensive research, the mainstay of cancer pain treatment is still non‐

Mechanism of Voltage Gating in Potassium Channels

Science, 2012
Open and Shut Case Voltage-sensing domains (VSDs) control the activity of voltage-gated ion channels to regulate the ion flow that underlies nerve conduction. Structural and biophysical studies have provided insight into voltage gating; however, understanding has been hindered by the lack of a crystal structure of a fully closed ...

Thermodynamics of a voltage-gated potassium channel

Physical Review E
In order to know how a single potassium channel works in its microscopic niche, a hybrid process about the observables of channel state and voltage is constructed, which comprises the interweaving kinetics of channel gating, voltage decay, and thermal noise. The formula of entropy production rates (i.e., power dissipation) is derived and the stationary

The voltage-gated potassium channels and their relatives

Nature, 2002
The voltage-gated potassium channels are the prototypical members of a family of membrane signalling proteins. These protein-based machines have pores that pass millions of ions per second across the membrane with astonishing selectivity, and their gates snap open and shut in milliseconds as they sense changes in voltage or ligand concentration.

Voltage-Gated Potassium Channels in Cell Proliferation

Physiology, 2004
It is commonly accepted that cells require K+channels to proliferate. The role(s) of K+channels in the process is, however, poorly understood. Cloning of K+channel genes opened the possibility to approach this problem in a way more independent from pharmacological tools.
