I t was pointed out by Osterhout I that substances which increase the electrical conductivity of tissues are antagonized by those which decrease it. An illustration of this is seen in antagonism between NaC1 (which increases conductivity) and Na taurocholate ~ (which decreases it). This case has additional interest as an example of antagonism between anions as well as of antagonism between orga...

kashan aquifer is adjacent to salt lake. because of this adjacency, the saline water of the lake has moved to the aquifer. in this study groundwater quality of the aquifer was simulated using artificial neural network (ann) model. for this purpose, the dominant ion of water was first determined by piper diagram. results showed that the sodium chloride is the dominant ion of water and so it was ...

The adsorption, micelle formation, and salting out of sodium dodecyl sulfate in the presence of sodium chloride were studied from the viewpoint of their mixed adsorption and aggregate formation. The surface tension of aqueous solutions of a sodium chloride-sodium dodecyl sulfate mixture was measured as a function of the total molality and composition of the mixture. Phase diagrams of adsorption...

We have previously reported that 1) selective dietary sodium loading (without chloride) does not produce hypertension in rats of the Dahl salt-sensitive strain (DS) and 2) selective chloride loading (without sodium) lowers plasma renin activity in the intact Sprague-Dawley rat maintained on a low NaCl diet. The present study examined the effect of selective dietary chloride loading on two model...

Obligatory, coupled cotransport of Na(+), K(+), and Cl(-) by cell membranes has been reported in nearly every animal cell type. This review examines the current status of our knowledge about this ion transport mechanism. Two isoforms of the Na(+)-K(+)-Cl(-) cotransporter (NKCC) protein (approximately 120-130 kDa, unglycosylated) are currently known. One isoform (NKCC2) has at least three altern...

1. Uptake of l-glutamate by Halobacterium salinarium is dependent on high concentrations of sodium chloride in the environment. When the sodium chloride is replaced by isomolar concentrations of potassium chloride, sodium acetate or potassium acetate, only negligible uptake occurs. 2. Most of the glutamate taken up can be shown to be in the cells in the free state and at a concentration of at l...

Parfentjev, I. A. (Institute of Applied Biology, New York, N.Y.), and Anna R. Catelli. Tolerance of Staphylococcus aureus to sodium chloride. J. Bacteriol. 88:1-3. 1964.-The tolerance of Staphylococcus aureus to high concentrations of sodium chloride in liquid medium has been reported. We found that S. aureus grows at 37 C in Tryptose Phosphate Broth saturated with sodium chloride. No differenc...

Distal nephron function of the rat during lithium chloride infusion. Chronic lithium (Li) administration in the rat leads to reduced renal concentration (TCH20) without alterations in renal dilution (CH), To examine the acute effects of lithium on TH2O and C1120, rats were infused with a solution composed of 1% sodium chloride and 1% lithium chloride or a 0.225% lithium chloride solution at rat...

Nucleus accumbens-1 (NAC1), a nuclear factor belonging to the BTB/POZ gene family, has emerging roles in cancer. We report here that NAC1 acts as a negative regulator of cellular senescence in transformed and nontransformed cells, and dysfunction of NAC1 induces senescence and inhibits its oncogenic potential. We show that NAC1 deficiency markedly activates senescence and inhibits proliferation...

Colorectal carcinoma (CRC) is one of the most common types of malignancy worldwide. Recently, neoadjuvant chemotherapy has become an important treatment strategy for CRC. However, treatment frequently fails due to the development of chemoresistance, which is a major obstacle for positive prognosis. However, the underlying mechanisms of chemoresistance remain unclear. The present study assessed ...
