introduction: we have recently reported the presence of two potassium currents with 598 and 368 ps conductance in the rough endoplasmic reticulum (rer) membrane. the 598 ps channel was voltage dependent and atp sensitive. however, the 368 ps channel was rarely observed and its identity remained obscure. since cationic channels in intracellular organelles such as mitochondria and rer play import...

Introduction: we have recently reported the presence of two potassium currents with 598 and 368 pS conductance in the rough endoplasmic reticulum (RER) membrane. The 598 pS channel was voltage dependent and ATP sensitive. However, the 368 pS channel was rarely observed and its identity remained obscure. Since cationic channels in intracellular organelles such as mitochondria and RER play imp...

Background: Acute blood purification (ABP) therapy is used regularly in the clinical setting and reportedly alleviates organ failure associated with severe systemic inflammatory responses, leading to reduced mortality. The present study aimed to determine whether there is a difference in efficacy between polysulfone (PS) membranes, which are currently used regularly in the clinical setting, and...

Introduction: Human embryonic stem cells (hESCs) are pluripotent cells that can proliferate and differentiate to many cell types. Their electrophysiological properties have not yet been chracterzed. In this study, the passive properties (such as resting membrane potential, input resistance and capacitance) and the contribution of delayed rectifier K+ channel currents to the membrane conducta...

Phosphatidylserine (PS) in the plasma membrane of single apoptotic cells was detected using luminol electrochemiluminescence for the first time. Membrane PS was converted by aqueous phospholipase D and L-amino acid oxidase to generate hydrogen peroxide, inducing electrochemically generated luminescence. The successful observation of PS in the cellular membrane provided a special strategy for th...

Abstract The development of new materials for air filtration and particulate matter (PM) pollution is critical to solving global environmental issues that threaten human health accelerate the greenhouse effect. In this study, a novel electrospun polystyrene-SiO 2 nanoparticle (PS-SNP) fibrous membrane was explored by single-step strategy obtain composite multi-layered filter masks. addition, pe...

Photosystem II (PS II) complexes are membrane protein complexes that are composed of >20 distinct subunit proteins. Similar to many other membrane protein complexes, two PS II complexes are believed to form a homo-dimer whose molecular mass is approximately 650 kDa. Contrary to this well known concept, we propose that the functional form of PS II in vivo is a monomer, based on the following obs...
