The intracellular solute composition of the salt-tolerant yeast Debaryomyces hansenii was studied in glucose-limited chemostat cultures at different concentrations of NaCl (4 mM, 0.68 M, and 1.35 M). A strong positive correlation between the total intracellular polyol concentration (glycerol and arabinitol) and medium salinity was demonstrated. The intracellular polyol concentration was suffici...

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...

The globin gene is preferentially sensitive to digestion by DNase I in erythrocyte chromatin but not in brain, fibroblast, or oviduct chromatin. Elution of the erythrocyte chromatin with 0.35 M NaCl leads to no detectable change in the gross structure of individual nucleosomes; however, in this depleted chromatin the globin gene is no longer preferentially sensitive to DNase I. Reconstitution o...

Gel filtration and sedimentation studies have previously established that the vertebrate animal core histone octamer is in equilibrium with an (H3-H4)2 tetramer and an H2A-H2B dimer [Eickbush, T. H., & Moudrianakis, E. N. (1978) Biochemistry 17, 4955-4964; Godfrey, J. E., Eickbush, T. H., & Moudrianakis, E. N. (1980) Biochemistry 19, 1339-1346]. We have investigated the core histone octamer of ...

The influence of salt concentrations on the performance of reverse electrodialysis (RED) stacks has rarely been investigated using thermolytic salts such as NH4HCO3, that can be regenerated using waste heat and can be set at any desired concentration below saturation limits. Here, power densities produced by a RED stack were first investigated using different NaCl concentrations, and then teste...

1. Differences in the fragility of human red cells are observed in equimolar solutions of the chlorides of the monovalent cations. The cells are most fragile in LiCl and least fragile in NaCl, the salts falling in the order Li > K >== Rb > Cs > Na. 2. The difference between the tonicity-volume relations in systems containing LiCl and systems containing NaCl lies in the molarity of the solution ...

Solubilisation of myofibrillar proteins in physiological or low ionic strength solutions is essential for their utilisation as supplementary protein food. In order to achieve low ionic strength solubility, ultrasonication as a physical force has been introduced as an effective method to shift the solubility range of myofibrillar proteins from high to low ionic medium. In this study, change in t...

The cell migration plays a crucial role in a variety of physiological and pathological processes and can be regulated by the cell-substrate interactions. We found previously that the poly(sodium 4-styrenesulphonate) (PSS)/poly(diallyldimethylammonium) chloride (PDADMAC) multilayers post-treated in 1-5 M NaCl solutions result in continuous changes of their physico-chemical properties such as thi...

HeLa cell heterogeneous nuclear RNA derived from high-molecular-weight nuclear ribonucleoprotein (RNP) particles contains oligo(U) sequences of 15-50 nucleotides base-paired with poly(A). These duplexes are resistant to pancreatic RNase at 0.5 M NaCl in native RNP, remain so after chemical deproteinization of the RNP digests, and then copurify with poly(A) on oligo(dT)-cellulose chromatography....
