Huang, Wan, Alan F. Sved, and Edward M. Stricker. Vasopressin and oxytocin release evoked by NaCl loads are selectively blunted by area postrema lesions. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R732–R740, 2000.—The present study investigated the effect of area postrema lesions (APX) on stimulated neurohypophysial secretion of vasopressin (VP) and oxytocin (OT) in conscious ra...

Microbial communities in shale oil fields are still poorly known. We obtained samples of injection, produced and facility waters from a Bakken shale oil field in Saskatchewan, Canada with a resident temperature of 60°C. The injection water had a lower salinity (0.7 Meq of NaCl) than produced or facility waters (0.6-3.6 Meq of NaCl). Salinities of the latter decreased with time, likely due to in...

The effect of Cu2+ in bulk solution on pitting corrosion resistance extra-high-purity type 316 stainless-steel was investigated. Pitting occurred 0.1 M NaCl-1 mM CuCl2, whereas not initiated NaCl. Although deposition the surface regardless a potential region had no influence passive film formation. decrease CuCl2 resulted from deposited Cu or compound and continuous supply surface.

Quinoa (Chenopodium quinoa Willd.) is an Andean crop with an edible seed that both contains high protein content and provides high quality protein with a balanced amino acid profile in embryonic tissues. Quinoa is a halophyte adapted to harsh environments with highly saline soil. In this study, four quinoa varieties were grown under six salinity treatments and two levels of fertilization, and t...

Adult Fischer 344 (F344) rats fail to display any preference for NaCl solutions at concentrations typically preferred by other rat strains. To determine whether this behavior is due to a strain difference in NaCl detection threshold, a conditioned taste aversion (CTA) was first established to a suprathreshold concentration of NaCl (0.1 M). Then, a series of dilute NaCl solutions, ranging from 0...

Production of extracellular amylase was demonstrated under conditions of high salinity in aerobically cultivated culture of a newly isolated moderately halophilic Gram-positive coccus, designated strain F in basal medium containing peptone from meat, yeast extract, NaCl (7% w/v) and starch. Biochemical and physiological characterization along with 16S rRNA sequence analysis placed F in the genu...

Pyrimidine oligonucleotides containing alternating anionic and stereo-uniform cationic N-(dimethylamino-propyl)phosphoramidate linkages [e.g. d(T+T-)7T, d(T+T-)2(T+C-)5T and (U'+U'-)7dT, where U' is 2'-O-methyluridine)] are shown to bind to complementary double-stranded DNA segments in 0.1 M NaCl at pH 7 to form triple-stranded complexes with the pyrimidine.purine.pyrimidine motif. For each of ...

In this work, the rise characteristics of a single H2 bubble, in ellipsoidal regime, (i) water, (ii) electrolyte (2 M, 4.5 M NaCl) solution and (iii) various concentrations mixture (up to 6.4 1:5 weight fraction NaCl-NaClO3), have been studied, at temperatures up 80°C. Our results show that both individual collective effects temperature concentration on velocity bubble shape are purely dependen...

Soluble complexes of poly (U) and adenylic nucleotides in NaCl solutions were studied by scanning microcalorimetry. The melting enthalpies, delta Hm, of poly (U) complexes with adenosine, 2',3' -cAMP, 2'(3')-AMP, 5-AMP, ADP, ATP in 1 M NaCl are 50.5; 45.0; 42.9; 28.6; 26.1 and 25.6 kJ/mole triplets, respectively. Delta Hm is independent of the complex melting temperature, Tm. The calorimetric e...

The solubilization of nucleosomes and histone H1 with increasing concentrations of NaCl has been investigated in rat liver nuclei that had been digested with micrococcal nuclease under conditions that did not substantially alter morphological properties with respect to differences in the extent of chromatin condensation. The pattern of nucleosome and H1 solubilization was gradual and noncoordin...
