This study demonstrates the first use of polydimethylsiloxane (PDMS) immobilized on a rotating disk for the extraction of copper from aqueous matrices and its subsequent direct determination by solid phase UV-Visible spectrophotometry. To accomplish the solid-phase extraction and the...

The effects of amiloride on the labellar taste receptor cells of the fleshfly Boettcherisca peregrina.

Journal of insect physiology

Sadakata T, Hatano H, Koseki T, Koganezawa M, Shimada I.
PMID: 12770084
J Insect Physiol. 2002 May;48(5):565-570. doi: 10.1016/s0022-1910(02)00074-4.

Amiloride is known to inhibit the taste response of vertebrates to salt by blocking the amiloride-sensitive sodium channel. In this study, we investigated electrophysiologically the effect of amiloride on the taste response of the fleshfly Boettcherisca peregrina. When 0.5...

The Effects of G Protein Modulators on the Labellar Taste Receptor Cells of the Fleshfly (Boettcherisca peregrina).

Journal of insect physiology

SHIMADA, KOGANEZAWA M.
PMID: 12769906
J Insect Physiol. 1997 Mar;43(3):225-233. doi: 10.1016/s0022-1910(96)00096-0.

A nonhydrolyzable G protein activator (guanosine 5'-O-(3-thiotriphosphate); GTPgammaS) and a G protein inhibitor (guanosine 5'-O-(2-thiodiphosphate); GDPbetaS) were introduced into the labellar taste receptor cells of the fleshfly by treatment of their receptive membranes beneath the tip opening of the...

Multiple receptor sites for nucleotide reception in the labellar taste receptor cells of the fleshfly Boettcherisca peregrina.

Journal of insect physiology

Furuyama A, Koganezawa M, Shimada I.
PMID: 12770372
J Insect Physiol. 1999 Mar;45(3):249-255. doi: 10.1016/s0022-1910(98)00120-6.

Nucleotides applied to the labellar chemosensory hair of the fleshfly, Boettcherisca peregrina, stimulated the taste receptor cells. Adenosine 5'-diphosphate (ADP) evoked a large response of the sugar receptor cell (sugar response) and guanosine 5'-diphosphate (GDP) evoked a large response...

PMID: 22924046
Case Rep Med. 2012;2012:575470. doi: 10.1155/2012/575470. Epub 2012 Aug 08.

We report a case of Strongyloides stercoralis hyperinfection syndrome with central nervous system involvement, in a patient with late human immunodeficiency virus (HIV) infection starting antiretroviral therapy, in whom Strongyloides stercoralis larvae and Cryptococcus neoformans were isolated antemortem from...

Biphasic activation of β-arrestin 1 upon interaction with a GPCR revealed by methyl-TROSY NMR.

Nature communications

Shiraishi Y, Kofuku Y, Ueda T, Pandey S, Dwivedi-Agnihotri H, Shukla AK, Shimada I.
PMID: 34887409
Nat Commun. 2021 Dec 09;12(1):7158. doi: 10.1038/s41467-021-27482-3.

β-arrestins (βarrs) play multifaceted roles in the function of G protein-coupled receptors (GPCRs). βarrs typically interact with phosphorylated C-terminal tail (C tail) and transmembrane core (TM core) of GPCRs. However, the effects of the C tail- and TM core-mediated...

Targeting the cryptic sites: NMR-based strategy to improve protein druggability by controlling the conformational equilibrium.

Science advances

Mizukoshi Y, Takeuchi K, Tokunaga Y, Matsuo H, Imai M, Fujisaki M, Kamoshida H, Takizawa T, Hanzawa H, Shimada I.

Cryptic ligand binding sites, which are not evident in the unligated structures, are beneficial in tackling with difficult but attractive drug targets, such as protein-protein interactions (PPIs). However, cryptic sites have thus far not been rationally pursued in the...

Determination of pesticides in river water using rotating disk sorptive extraction and gas chromatography-mass spectrometry.

Talanta

Giordano A, Richter P, Ahumada I.
