Extracellular quaternary ammonium blockade of transient receptor potential vanilloid subtype 1 channels expressed in Xenopus laevis oocytes.
Mol. Pharmacol. 82(6) , 1129-35, (2012) Transient receptor potential vanilloid subtype 1 (TRPV1) channels are essential nociceptive integrators in primary afferent neurons. These nonselective cation channels are inhibited by local anesthetic compounds through an undefined mechanism. Here, we show t... |

Remarkably regioselective deacylation of cellulose esters using tetraalkylammonium salts of the strongly basic hydroxide ion.
Carbohydr. Polym. 111 , 25-32, (2014) Tetraalkylammonium hydroxides have been found to mediate regioselective deacylation of cellulose esters. This deacylation surprisingly shows substantial selectivity for the removal of the acyl groups at O-2/3, affording cellulose-6-O-esters by a simple, effic... |

Use of ion-pairing reagent for improving iodine speciation analysis in seaweed by pressure-driven capillary electrophoresis and ultraviolet detection.
J. Chromatogr. A. 1379 , 112-7, (2015) This study achieved resolution improvement for iodine speciation in the presence of an ion-pairing reagent by a pressure-driven capillary electrophoresis (CE) system. Addition of 0.01mM tetrabutyl ammonium hydroxide (TBAH) as the ion-pairing reagent into the ... |

Tackling the challenge of selective analytical clean-up of complex natural extracts: the curious case of chlorophyll removal.
Food Chem. 163 , 147-53, (2014) Alkaline saponification is often used to remove interfering chlorophylls and lipids during carotenoids analysis. However, saponification also hydrolyses esterified carotenoids and is known to induce artifacts. To avoid carotenoid artifact formation during sap... |

Differential role of ethylene and hydrogen peroxide in dark-induced stomatal closure.
Pak. J. Biol. Sci. 16(24) , 1991-6, (2013) Regulation of stomatal aperture is crucial in terrestrial plants for controlling water loss and gaseous exchange with environment. While much is known of signaling for stomatal opening induced by blue light and the role of hormones, little is known about the ... |

Genetic interference with peroxisome proliferator-activated receptor γ in smooth muscle enhances myogenic tone in the cerebrovasculature via A Rho kinase-dependent mechanism.
Hypertension 65(2) , 345-51, (2015) Myogenic responses by resistance vessels are a key component of autoregulation in brain, thus playing a crucial role in regulating cerebral blood flow and protecting the blood-brain barrier against potentially detrimental elevations in blood pressure. Althoug... |

Diabetes impairs the atrial natriuretic peptide relaxant action mediated by potassium channels and prostacyclin in the rabbit renal artery.
Pharmacol. Res. 66(5) , 392-400, (2012) Diabetes is associated with increased prevalence of hypertension, cardiovascular and renal disease. Atrial natriuretic peptide (ANP) plays an important role in cardiovascular pathophysiology and is claimed to have cardioprotective and renoprotective effect in... |

TREK-1 currents in smooth muscle cells from pregnant human myometrium.
Am. J. Physiol. Cell Physiol. 305(6) , C632-42, (2013) The mechanisms governing maintenance of quiescence during pregnancy remain largely unknown. The current study characterizes a stretch-activated, tetraethylammonium-insensitive K(+) current in smooth muscle cells isolated from pregnant human myometrium. This s... |

Cellular elements for seeing in the dark: voltage-dependent conductances in cockroach photoreceptors.
BMC Neurosci. 13 , 93, (2012) The importance of voltage-dependent conductances in sensory information processing is well-established in insect photoreceptors. Here we present the characterization of electrical properties in photoreceptors of the cockroach (Periplaneta americana), a noctur... |

Evaluation of the functional importance of organic cation transporters on the ocular disposition of its intravitreally injected substrate in rabbits.
Curr. Eye Res. 37(12) , 1127-35, (2012) To evaluate the functional role of organic cation transporters (OCT) and ocular tissue distribution of intravitreally injected OCT substrate tetraethylammonium (TEA) in presence of OCT blocker (quinidine).New Zealand albino rabbits of either sex were used. In... |
