Direct observation of the state of 23Na' ions in intact cells and tissues by noninvasive NMR spectroscopy: intracellular Na+ ions in human normal and leukemic lymphocytes. In Ions, Cell Proliferation, and Cancer. A. L. Boynton, W. L. McKeehan, and J. F. Whitfield, editors. Academic ...
Release of charged neurotransmitter molecules through a narrow fusion pore requires charge compensation by other ions. It has been proposed that this may occur by ion flow from the cytosol through channels in the vesicle membrane, which would generate a net outward current. This hypothesis was teste...
Chapter 4 The Direct Measurement of K, Cl, Na, and H Ions in Bullfrog Tubule CellsThis chapter describes the measurement of some of the intracellular ionic activities of Na + , K + , Cl - , HCO 3 - , and pH in the tubular lumen, cell, and surrounding interstitium in the proximal ...
By virtue of the applied periodic boundary conditions, the coordinates of an ion exiting the simulation box from the top (bottom) are wrapped around to re-enter the box from the bottom (top) in the output trajectory produced by Anton. However, unwrapped z coordinates must be used to ...
Cells for determination of non-specific uptake were preincubated with 200 mM imipramine for 30 min, while cells for determination of total uptake were incubated with PBSCM. Uptake was initiated by the addition of 40 ml of a dilution of the 8 NATURE COMMUNICATIONS | 7:11673 | DOI: 10.1038/...
Cation/proton antiporters (CPAs), which include Na+/H+ exchangers, are evolutionarily ancient transporters present in most species from prokaryotes to higher eukaryotes. Many of them are expressed in epithelial cells or various organs, where they utilize
FGF acidic, also known as FGF1, ECGF, and HBGF-1, is a 17 kDa nonglycosylated member of the FGF family of mitogenic peptides. FGF acidic, which is produced by multiple cell types, stimulates the proliferation of all cells of mesodermal origin and many cells of neuroectodermal, ectodermal,...
which would mean that there exists a third type of water in beryl. The origin of protons and OH−ions in beryl is discussed and it is suggested that the plugs in the beryl channels are CO2−3ions. Diffusion of OH−ions and natural radiation may have led to the creation of NO3and...
coli cells was carried out as follows: the mannose-functionalized nanoparticles (30 mg) were added to PBS buffer (10 mM, pH 7.4) containing 1 mM Mn2+ and 1 mM Ca2+ and the E. coli cells. After incubation for 2 h at 4 ◦C with gentle shaking, the samples were separated by ...
