Expression and function of ATP-dependent potassium channels in zebrafish islet β-cells [PDF]

, 2017
ATP-sensitive potassium channels (K(ATP) channels) are critical nutrient sensors in many mammalian tissues. In the pancreas, K(ATP) channels are essential for coupling glucose metabolism to insulin secretion.

Engineering Porous Hollow Metal‐Poly(Heptazine Imide) Spheres: An Optimized Synthetic Strategy for Controlling Surface, Morphology, and Properties

Advanced Functional Materials, EarlyView.
Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for

Potassium channel‐mediated NO‐induced vasodilation during maturation: Dominance of Kv7 channels

FASEB BioAdvances
Maturation represents a process characterized by adaptive changes, particularly in the circulatory system. However, it is not known whether, in neonates, potassium channels contribute to NO‐induced vasorelaxation at all and, if so, which potassium ...

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Diabetes mellitus and ischemic heart disease. the role of ion channels [PDF]

, 2018
Diabetes mellitus is one the strongest risk factors for cardiovascular disease and, in particular, for ischemic heart disease (IHD). The pathophysiology of myocardial ischemia in diabetic patients is complex and not fully understood: some diabetic ...

Metal‐Organic Framework Embedded Electrospun Fibrous Membranes‐Based Hybrid Nanogenerators with Hierarchical Modified Polyamide Films for Mechanical Energy Harvesting and IoT Applications

Advanced Functional Materials, EarlyView.
Hybrid nanogenerator (HNG) based on a zinc‐metal‐organic framework‐loaded fibrous film integrated with a hierarchically modified nylon film having micropatterns and micropores is fabricated via an electrospinning technique, and its electrical properties are optimized. The HNGs are incorporated into wearable garments and automobile systems for practical

Effects of small conductance calcium activated potassium channels in atrial myocytes [PDF]

, 2017
Among the different potassium channels present in cardiac myocytes, the small conductance Ca2+ activated potassium channels (SK channels) are particular because they are affected by changes in intracellular calcium.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Optogenetic techniques for the study of native potassium channels

Frontiers in Molecular Neuroscience, 2013
Optogenetic tools were originally designed to target specific neurons for remote control of their activity by light and have largely been built around opsin-based channels and pumps.
