The Journal of Physical Chemistry, 96, 7137-7137 (1992)

Presynaptic release probability and readily releasable pool size are regulated by two independent mechanisms during posttetanic potentiation at the calyx of Held synapse.

Jae Sung Lee et al.

The Journal of neuroscience : the official journal of the Society for Neuroscience, 28(32), 7945-7953 (2008-08-08)

At the immature calyx of Held, the fast decay phase of a Ca(2+) transient induced by tetanic stimulation (TS) was followed by a period of elevated [Ca(2+)](i) for tens of seconds, referred to as posttetanic residual calcium (Ca(res)). We investigated

Identification of a glycine motif required for packing in EmrE, a multidrug transporter from Escherichia coli.

Yael Elbaz et al.

The Journal of biological chemistry, 283(18), 12276-12283 (2008-03-07)

Glycine residues may play functional and structural roles in membrane proteins. In this work we studied the role of glycine residues in EmrE, a small multidrug transporter from Escherichia coli. EmrE extrudes various drugs across the plasma membrane in exchange

Chemical speciation of chromium(III) and (VI) using phosphonium cation impregnated polyurethane foams prior to their spectrometric determination.

M S El-Shahawi et al.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 27(7), 757-757 (2011-07-13)

Fast and selective sorptions of Cr(VI) species from aqueous media onto tetraphenylphosphonium bromide (TPP(+) · Br(-)) physically immobilized polyurethane foams (PUFs) sorbent were achieved. Based on the Scatchard model of binding sites of the PUFs and Langmuir and Dubinin-Radushkevich (D-R)
