Numerous studies have reported the mean value for Na+-Li+ countertransport to be increased in red blood cells from patients with essential hypertension. Although concomitant variables including age, body size, national origin, geographic location, gender, and family history of hypertension may affect Na+-Li+ countertransport values, most case-control studies have failed to assess the contributi...

There is probably a heterogeneous etiology for essential hypertension (EHT), and abnormal erythrocyte sodium-lithium countertransport (Na/Li CT) is common in a subgroup of patients with a strong family history of hypertension and cardiovascular disease (EHT-FH patients). The aim of this study was to test the hypothesis that altering a membrane thiol protein could mimic the abnormal Na/Li CT obs...

BACKGROUND Numerous reports have presented evidence for a positive association between the maximal velocity of the sodium-lithium countertransport (Na-Li CT) in erythrocytes and hypertension. The nature of this association remains to be clarified. METHODS AND RESULTS This report presents correlates of Na-Li CT in a population sample of 3,591 people aged 5-74 years. Males had higher mean age-s...

Both Na+/Li+ countertransport and electrochemical proton gradient (delta mu(H+))-induced Na+ and H+ fluxes are increased in erythrocytes from patients with essential hypertension. It was assumed that these abnormalities are related to ubiquitous (housekeeping) forms of the Na+/H+ exchanger (NHE-1). To examine this hypothesis, we compared kinetic and regulatory properties of erythrocyte Na+/Li+ ...

To evaluate the potential of Na-ion batteries, we contrast in this work the difference between Na-ion and Li-ion based intercalation chemistries in terms of three key battery properties – voltage, phase stability and diffusion barriers. The compounds investigated comprise the layered AMO2 and AMS2 structures, the olivine and maricite AMPO4 structures, and the NASICON A3V2(PO4)3 structures. The ...

This is the first examination of sensory receptive properties and associated electrophysiological properties in vivo of dorsal root ganglion (DRG) neurons that express the TTX-resistant sodium channel Na(v)1.9 (NaN). Intracellular recordings in lumbar DRGs in Wistar rats enabled units with dorsal root C-, Adelta-, or Aalpha/beta-fibers to be classified as nociceptive, low-threshold mechanorecep...

Cells of Porphyra perforata, a red marine alga, accumulate K in the absence of concomitant Na or Li extrusion while immersed in Li- or Mg-sea waters lacking Na. This suggests that the coupling observed between K and Na transport is facultative. No evidence is obtained for net extrusion of Li. Na efflux, with the concentration gradient, is facilitated by K and is proportional to the cellular Na ...

The hydrogen storage system LiH + NH(3) ↔ LiNH(2) + H(2) is one of the most promising hydrogen storage systems, where the reaction yield can be increased by replacing Li in LiH with other alkali metals (Na or K) in order of Li < Na < K. In this paper, we have studied the alkali metal M (M = Li, Na, K) dependence of the reactivity of MH with NH(3) by calculating the potential barrier of the H(2)...
