Pharmacology of Cardiac Potassium Channels [PDF]

, 2010
Cardiac K(+) channels are cardiomyocyte membrane proteins that regulate K(+) ion flow across the cell membrane on the electrochemical gradient and determine the resting membrane potential and the cardiac action potential morphology and duration. Several K(+) channels have been well studied in the human heart.

High temperature sensitivity is intrinsic to voltage-gated potassium channels. [PDF]

, 2014
Temperature-sensitive transient receptor potential (TRP) ion channels are members of the large tetrameric cation channels superfamily but are considered to be uniquely sensitive to heat, which has been presumed to be due to the existence of an ...

A Strong and Water‐Retaining Biomass Adhesive Inspired by Tofu

Advanced Functional Materials, EarlyView.
Drawing inspiration from the formation mechanism of the traditional food tofu, a strong and water‐retaining adhesive is designed using the soybean meal (SM) oxidized by glucose oxidase (GOx) and calcium sulfate oligomer (CSO). This design strategy effectively addresses the conflicting requirements of water‐resistant bonding strength and water retention

Tuning the Hydrogen Bond Network Inside the Helmholtz Plane for Industrial Hydrogen Evolution

Advanced Functional Materials, EarlyView.
The hydrogen bond network within the Helmholtz plane, a key component affecting the hydrogen evolution kinetics, remains far from having a consensus owing to the lack of fundamental understanding. Herein, it is discovered that the introduction of the atomic electric field generated by the weak Ru─Ga bonds can further improve the proportion of 4 ...
