OBJECTIVE To study the synergism between neuropeptides and lithium ions. MATERIAL AND METHODS An experimental model of stroke (chronic bilateral occlusion of the common carotid arteries in rats), neuronal culture studies, histomorphological analyses, determination of micronutrient profile of brain substrates were used. RESULTS A complex of experimental studies revealed that the effect of ce...

BACKGROUND This work aimed to provide useful information on the incidence of the choice of formulation in semi-solid preparations of iron-oxide nanoparticles (IONs). The appropriate analytical methods to assess the IONs physical stability and the effect of the semi-solid preparations on IONs human skin penetration were discussed. The physical stability of IONs (Dh = 31 ± 4 nm; ζ = -65 ± 5 mV) l...

Polymeric membrane ion-selective electrodes (ISEs) have become attractive tools for trace-level environmental and biological measurements. However, applications of such ISEs are often limited to measurements with low levels of electrolyte background. This paper describes an asymmetric membrane rotating ISE configuration for trace-level potentiometric detection with a high-interfering background...

Plasmid-determined resistance to cadmium has only been found with plasmids from Staphylococcus aureus. Resistance to cadmium was associated with a lower accumulation of Cd(2+) ions by the plasmid-bearing resistant cells. Cadmium accumulation by susceptible cells was energy dependent and had those characteristics usually associated with a transmembrane active transport system. There was a specif...

Abstract. As proposed by Saka (2019), plasma injections arising out of the auroral ionosphere (ionospheric injection) are a characteristic process polar at substorm onset. The ionospheric injection is triggered westward electric fields transmitted from convection surge in magnetosphere field line dipolarization. Localized result local accumulation electrons and ions, which produce electrostatic...

Low-energy reactive ion scattering ~RIS! experiments show that NaCl dissociates almost completely on condensed ice surfaces prepared on Ru~001! even at 100 K forming solvated ions. NaCl by itself does not dissociate on a Ru~001! substrate; however, submonolayer coverages of water sets-in dissociation. Na ions thus created are immobile such that they do not migrate across one water bilayer ~BL! ...
