Abstract:
BackgroundThe basolateral potassium channel in the distal convoluted tubule (DCT), comprising the inwardly rectifying potassium channel Kir4.1/Kir5.1 heterotetramer, plays a key role in mediating the effect of dietary potassium intake on the thiazide-sensitive NaCl cotransporter (NCC). The role of Kir5.1 (encoded by Kcnj16) in mediating effects of dietary potassium intake on the NCC and renal potassium excretion is unknown.MethodsWe used electrophysiology, renal clearance, and immunoblotting to study Kir4.1 in the DCT and NCC in Kir5.1 knockout (Kcnj16−/−) and wild-type (Kcnj16+/+) mice fed wi

Abstract:
Potassium-ion batteries (PIBs) are regarded as a potential substitute for LIBs owing to the benefits of potassium’s abundance, low cost, and high safety. Nonetheless, the practical implementation of potassium-ion batteries still encounters numerous challenges, with the selection and design of anode materials standing out as a key factor impeding their progress. Hard carbon, characterized by its amorphous structure, high specific surface area, and well-developed pore structure, facilitates the insertion/extraction of potassium ions, demonstrating excellent rate performance and cycling stability

Ecosystem-based approaches to nutrient management are needed to satisfy crop nutrient requirements while minimizing environmental impacts of fertilizer use. Applying crop residues as soil amendments can provide essential crop nutrient inputs from organic sources while improving nutrient retention, soil health, water conservation, and crop performance. Tree crop hulls, husks, and shells have been found to contain high concentrations of potassium across species including almond, cacao, coffee, pecan, and hazelnut. The objective of this review is to characterize organic sources of potassium focus

Forty years have transpired since tetraethylammonium was first used to selectively inhibit the potassiuin conductance in squid axons. Since then, a large body of work has emerged describing inhibitors of voltage-gated potassium currents in a variety of cells. The advent of molecular cloning techniques and the cloning of the potassium channel encoded by the Shaker locus in Drosophila has enabled detailed structure­ function studies of several potassium channel subunits. These breakthroughs have also recently enabled studies of the "toxinology" and pharmacology of specific potassium channel subu

This study uses the structural coordinates of the determined K+ channels to create comparative models of three diverse members of this family, with the aim of enabling a better understanding of the function of these channels. The K+ channel of primary interest is the hERG K+ channel. The pharmacology of this channel is of considerable interest as serendipitous block of K+ conduction pore may result in cardiac arrest. A set of known antagonists have been docked into novel comparative models of hERG to propose how these drugs interact with the channel. The models have also been subjected to mole

Owing to the materials’ characteristic properties, structures and linings constructed from these materials are designed differently than those constructed of organic polymer composites.

การวิจัยและพัฒนาเพื่อเพิ่มผลผลิตสาหร่ายทะเลขนาดใหญ่ด้วยการใช้น้ำหมักชีวภาพจากวัสดุดิบ เหลือใช้ทางการเกษตรและการประมงสำหรับทดแทนปุ๋ยเคมี พบว่า คุณค่าของธาตุอาหารที่เหมาะสมใน การเจริญเติบโตของพืช ได้แก่ ไนโตรเจน (Nitrogen, N) ฟอสฟอรัส (Phosphorus, P) และโปแตสเซียม (Potassium, K) ในน้ำหมักชีวภาพจากวัสดุเหลือใช้ทางการประมงมีคุณค่าเหมาะสมต่อการเจริญเติบโต ของสาหร่ายทะเลขนาดใหญ่ที่น้ำมาใช้ในการวิจัยครั้งนี้ คือ สาหร่ายผักกาดทะเล สาหร่ายพวงองุ่น และ สาหร่ายผมนาง มากกว่าธาตุอาหารที่ได้จากน้ำหมักชีวภาพจากวัสดุเหลือใช้ทางการเกษตร โดยการเลี้ยง สาหร่ายผักกาดทะเลด้วยน้ำหมักชีวภาพจากวัสดุเหลือใช้ทางการประมง
