Potassium release through ATP-sensitive potassium (K(ATP)) channels contributes to hypoxic vasodilation in the skeletal muscle vascular bed: It is uncertain whether K(ATP) channels on muscle cells contribute to the process. Potassium from muscle cells must cross the interstitial space to reach the vascular tissues, whereas that from vascular endothelium would have a higher concentration in veno...

The human neuroblastoma clone SH-SY5Y expresses potassium-, carbachol-, and calcium ionophore A23187-evoked, calcium-dependent release of [3H]noradrenaline. Release in response to carbachol and potassium was greater than additive. Atropine (Ki = 0.33 nM), hexahydrosiladifenidol (Ki = 18 nM), and pirenzepine (Ki = 1,183 nM) completely inhibited the carbachol-evoked noradrenaline release, an orde...

Some inflammatory stimuli trigger activation of the NLRP3 inflammasome by inducing efflux of cellular potassium. Loss of cellular potassium is known to potently suppress protein synthesis, leading us to test whether the inhibition of protein synthesis itself serves as an activating signal for the NLRP3 inflammasome. Murine bone marrow-derived macrophages, either primed by LPS or unprimed, were ...

Kinetic data on potassium release from and killing of Candida albicans by the four polyene antibiotics amphotericin B, amphotericin B methyl ester hydrochloride, nystatin, and nystatin methyl ester hydrochloride are presented. The nystatins were relatively more effective than the amphotericins in causing potassium release rather than killing. These data suggest that the aqueous channels or pore...

Plant litter decomposition and its effect on soil nutrients are important parts of the ecosystem material cycle, understanding these processes is key for species selection allocation to promote effective use in ecological tea gardens. In this study, situ method was used examine characteristics leaf Cinnamomum glanduliferum, Betula luminifera, Cunninghamia lanceolata, Pinus massoniana, Camellia ...

Calcareous soil suffers from deficiency in available of potassium due to its high contain CaCO3. So, it is important increase the availability potassium. Potassium release rate constant an indicator for ability supply A field experiments sulaimani governorate was conducted evaluate effect amendment with natural zeolite at (0 and 2 t ha-1), three levels Nano fertilizer (0, 5 10 kg conventional K...
