Left Atrial Posterior Wall Functional Remodeling in Paroxysmal and Persistent Atrial Fibrillation. A Pilot Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background The left atrial posterior wall (LAPW) is often targeted in atrial fibrillation (AF) ablation due to its shared properties with pulmonary veins. However, substrate‐guided approaches using structural markers have shown inconsistent results.

Four and a half LIM protein 1C (FHL1C) [PDF]

, 2011
Four-and-a-half LIM domain protein 1 isoform A (FHL1A) is predominantly expressed in skeletal and cardiac muscle. Mutations in the FHL1 gene are causative for several types of hereditary myopathies including X-linked myopathy with postural muscle atrophy

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

Journal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

CO2‐sensitive K+ channel traffic affects stomata and whole‐plant water use

Journal of Integrative Plant Biology, EarlyView.
CO2‐responsive regulation of membrane trafficking influences the density of the potassium ion (K+) channel KAT1 at the plasma membrane. CO2‐sensitive traffic, dependent on trafficking by the SNARE SYP121, impacts stomatal gas exchange and plant growth.

The emerging role of the inwardly rectifying K+ channels in autism spectrum disorders and epilepsy [PDF]

, 2011
Autism is a complex behavioral disorder that develops prior to age three years and is distinguished by high heritability. Many genes predisposing to autism spectrum disorders (ASDs) have been identified.

Potassium silicate improves cellular sodium homeostasis in wheat (Triticum aestivum L.) cultivars differing in salt resistance

Plant Biology, EarlyView.
Potassium silicate can decrease the uptake of sodium (Na+) into wheat cells by affecting the Na+ uptake channels and increasing ion homeostasis. Abstract Salinity causes negative impacts on crops. We investigated the effect of potassium silicate (K2SiO3) on the cytosolic uptake of sodium, [Na+]cyt, in mesophyll protoplasts of wheat cultivars differing ...

A Novel KCNJ2 Mutation Identified in an Autistic Proband Affects the Single Channel Properties of Kir2.1

Frontiers in Cellular Neuroscience, 2018
Inwardly rectifying potassium channels (Kir) have been historically associated to several cardiovascular disorders. In particular, loss-of-function mutations in the Kir2.1 channel have been reported in cases affected by Andersen-Tawil syndrome while gain-

Mu-Opioid Receptor Agonist Induces Kir3 Currents in Mouse Peripheral Sensory Neurons - Effects of Nerve Injury [PDF]

, 2018
Neuropathic pain often arises from damage to peripheral nerves and is difficult to treat. Activation of opioid receptors in peripheral sensory neurons is devoid of respiratory depression, sedation, nausea, and addiction mediated in the brain, and ...

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

An inwardly rectifying K+ channel is required for patterning. [PDF]

, 2012
Mutations that disrupt function of the human inwardly rectifying potassium channel KIR2.1 are associated with the craniofacial and digital defects of Andersen-Tawil Syndrome, but the contribution of Kir channels to development is undefined.
