the carrier facilitated transport of lithium picrate was studied using a series of non-cyclic polyethers containing different end groups and chain lengths through bulk liquid membrane (blm) and supported liquid membrane (slm) systems. the various membrane supports used are viz. ptfe, cellulose nitrate, and dialysis membrane and onion membrane. the amount of li+ transported depends upon the stru...

The bamboo-feeding species of tribe Evacanthini are reviewed. They include 9 genera and 13 species: Angustella leucostriata Li & Wang, 1991, Boundarus nigronotus Zhang, Zhang & Wei, 2010a, Carinata kelloggii (Baker, 1923), C. nigrofasciata Li & Wang, 1994a, Convexana fleura Chen, Yang & Li, 2012, Evacanthus repexus Distant, 1908, Onukia guttata Li & Wang, 1991, O. nigra Li & Wang, 1991, Parapyt...

BACKGROUND Although p21 is an important component that regulates cell-cycle progression, no consensus has been reached about its clinicopathological significance in esophageal squamous cell carcinoma (ESCC). In the present study, we investigated its prognostic significance and correlation with cyclin-D1 (CCND1) expression in ESCC. MATERIALS AND METHODS The p21 labeling index (LI) was calculat...

Amiloride-inhibitable Li+ influx in dog red blood cells is mediated by the Na+/H+ exchanger, NHE. However, there are substantial differences between the properties of Li+ transport and Na+ transport through the NHE. Li+ influx is activated by cell shrinkage, and Na+ influx is not, as we reported previously (Dunham PB, Kelley SJ, and Logue PJ. Am J Physiol Cell Physiol 287: C336-C344, 2004). Li+...

Angular distributions for the elastic scattering of 8 Li on 9 Be and the neutron transfer reactions Be have been measured with a 27 MeV 8 Li radioactive nuclear beam. Spectroscopic factors for 8 Li⊗n= 9 Li and 7 Li⊗n= 8 Li bound systems were obtained from the comparison between the experimental differential cross section and finite-range DWBA calculations with the code FRESCO. The spectroscopic...

We report that substitution of sodium with lithium (Li+) in the extracellular solution causes subtype-specific changes in the inward and outward currents of glutamate receptors (GluRs), without a shift in reversal potential. Li+ produces an increase of inward and outward currents of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate receptors and decreases in the currents of kainate (KA) and...

Diffusion of Li-ions in graphite is an essential elementary process in the current lithium-ion battery. The C-layers of graphite deform with Li due to relatively large size of Li-ion, act to confine the Li-ions, and thereby creates correlation between them. We address theoretically the thermal diffusivity of such correlated Li-ions in graphite by the hybrid quantum–classical simulation method. ...

To understand the behavior of Li in zircon, we have analyzed the abundance and isotopic composition of Li in three zircon standards (Plešovice, Qinghu and Temora) widely used for microbeam analysis of U-Pb ages and O-Hf isotopes. We have mapped Li concentration ([Li]) on large grains, using a Cameca 1280HR Secondary Ion Mass Spectrometer (SIMS). All zircons have a rim 5-20 μm wide in which [Li]...

The role of nanocrystalline materials in addressing the current challenges in energy storage has attracted large attention. Besides nanostructured B-type TiO 2 [1], being the fifth polymorph of titanium dioxide, Li intercalated nanocrystalline rutile is considered to act as a potential anode in inherently safe secondary Li ion batteries. In contrast to its coarse-grained counterpart, which is e...
