Unexpectedly high culturable diversity of moderately and extremely halophilic obligately chemolithoautotrophic sulfur-oxidizing bacteria (SOB) was discovered in the sediments of various hypersaline habitats, including chloride-sulfate lakes in Mongolia, Russia and Ukraine, a sea saltern in Slovenia and a deep-sea salt brine from the Mediterranean. Six different groups of halophilic SOB, includi...

Amiloride, a sodium channel blocker, is known to suppress NaCl responses of the chorda tympani (CT) nerve in various mammalian species. In mice, the NaCl suppressing effect of amiloride is reported to differ among strains. In C57BL mice, amiloride inhibits NaCl responses to about 50% of control, whereas no such clear suppression was evident in prior studies with 129 mice. However, evidence from...

27 28 Regulation of the putative amiloride and benzamil (Bz)-insensitive TRPV1t salt 29 taste receptor by phosphatidylinositol 4, 5-bisphosphate (PIP2) was investigated by 30 monitoring chorda tympani (CT) taste nerve responses to 0.1M NaCl solutions 31 containing Bz (5x10 M; a specific ENaC blocker) and resiniferatoxin (RTX; 0-10x10 32 M; a specific TRPV1 agonist) in Sprague-Dawley rats and in...

A single pair of Glu and Lys residues has been placed at four different spacings, and in both orientations, in an otherwise neutral alanine-glutamine peptide helix, and the contribution to helix stability of the different Glu-Lys interactions has been measured. The contribution from the interaction of each charged side chain with the helix macrodipole has also been determined. A side-chain inte...

Background: Salinity is a major environmental limiting factor, which affect agricultural production. The two Manilkara seedlings (M. roxburghiana and M. zapota) with high economic importance, could not adapt well to higher soil salinity and little is known about their proteomic mechanisms. Objectives: The mechanisms responsible ...

Thin film microfabrication technique was employed to fabricate a platinum based parallel-electrode structured impedance sensor. Electrochemical impedance spectroscopy (EIS) and equivalent circuit analysis of the small amplitude (±5 mV) AC impedance measurements (frequency range: 1 MHz to 0.1 Hz) at ambient temperature were carried out. Testing media include 0.001 M, 0.01 M, 0.1 M NaCl and KCl s...

Evidence supports the hypothesis that hyperinsulinemia, especially in obesity, contributes to salt-sensitive hypertension by enhancing sodium retention and blunting the normal reduction of sympathetic drive and vascular resistance that occurs during a high versus low NaCl diet. To address these issues, we studied 18 obese (body mass index, > 27 kg/m2) subjects younger than 45 years old with mil...

The binding properties of the Escherichia coli encoded single strand binding protein (SSB) to a variety of synthetic homopolynucleotides, as well as to single stranded M13 DNA, have been examined as a function of the NaCl concentration (25.0 degrees C, pH 8.1). Quenching of the intrinsic tryptophan fluorescence of the SSB protein by the nucleic acid is used to monitor binding. We find that the ...
