Advanced Functional Materials, EarlyView.In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

The role of potassium channels and calcium in the relaxation mechanism of magnesium sulfate on the isolated rat uterus [PDF]
Archives of Biological Sciences, 2019 MgSO4 is used as a tocolytic agent. It is considered to be a calcium channel antagonist, but a different mechanism of its action might be involved. The aim of this study was to examine the contribution of calcium concentrations and potassium channels in ...

Effect Of Site Selective Ion Channel Blocking on Action Potential [PDF]
arXiv, 2018 In this work we have theoretically investigated how the action potential generation and its associated intrinsic properties are affected in presence of ion channel blockers by adapting Gillepie's stochastic simulation technique on a very basic neuron of Hodgkin-Huxley type.

Correlation studies of open and closed states fluctuations in an ion channel: Analysis of ion current through a large conductance locust potassium channel [PDF]
, 2001 Ion current fluctuations occurring within open and closed states of large conductance locust potassium channel (BK channel) were investigated for the existence of correlation. Both time series, extracted from the ion current signal, were studied by the autocorrelation function (AFA) and the detrended fluctuation analysis (DFA) methods.

Sonochemical Functionalization of Glass
Advanced Functional Materials, EarlyView.A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

Genomic organization and chromosomal localization of the murine 2 P domain potassium channel gene Kcnk8: conservation of gene structure in 2 P domain potassium channels. [PDF]
, 2000 A 2 P domain potassium channel expressed in eye, lung, and stomach, Kcnk8, has recently been identified. To initiate further biochemical and genetic studies of this channel, we assembled the murine Kcnk8 cDNA sequence, characterized the genomic structure

Enhancement of Kv1.3 Potassium Conductance by Extremely Low Frequency Electromagnetic Field [PDF]
arXiv, 2015 Theoretical and experimental evidences support the hypothesis that extremely low-frequency electromagnetic fields can affect voltage-gated channels. Little is known, however, about their effect on potassium channels. Kv1.3, a member of the voltage-gated potassium channels family originally discovered in the brain, is a key player in important ...

Renal potassium channels: An overview [PDF]
Kidney International, 1995 The introduction of the patch-clamp technique by Neher and Sackmann [1, 2] has led to the successful exploration of potassium (K) channels in the kidney, allowing the definition of their properties, localization along the nephron and their regulation [3–6].
