Understanding the mechanisms used by halophytic members of the Poaceae to cope with salt stress will contribute to the knowledge necessary to genetically engineer salt-tolerant crops. In this study, we identified a genotype of Sporobolus virginicus, a halophytic turf grass collected in Japan, and investigated its growth rate, ion concentration and secretion, and proline concentration in compari...
UNLABELLED Urea and NaCl are elevated in the renal inner medulla. We now find that a high concentration of urea or NaCl increases reactive oxygen species (ROS) in mouse renal inner medullary (mIMCD3) cells in culture. Previously, high NaCl, but not high urea, was found to cause DNA double-strand breaks. We now tested whether high urea or NaCl causes oxidative damage to DNA or cellular proteins....
The behavioural responses of desert locusts, Schistocerca gregaria, to solutions of four behaviourally relevant chemicals (sodium chloride, sucrose, nicotine hydrogen tartrate and lysine glutamate) applied as droplets to the hind tarsus were analysed. All responses following within 1 s of chemical stimulation were local leg avoidance reflexes, and the probability of eliciting such a response in...
The major pathology in cystic fibrosis (CF) results from the colonization of the airways by the bacterium Pseudomonas aeruginosa. Indirect evidence suggests that this colonization occurs because the thin (10 μm) film of liquid that lines the airways (so-called airway surface liquid; Fig. 1) is saltier in CF patients than in healthy individuals and the endogenous antibiotics that are secreted by...
Effects of gustatory nerve transection on salt taste have been studied extensively in rats and hamsters but have not been well explored in the mouse. We examined the effects of chorda tympani (CT) nerve transection on NaCl taste preferences and thresholds in outbred CD-1 mice using a high-throughput phenotyping method developed in our laboratory. To measure taste thresholds, mice were condition...
This study was conducted to evaluate the effect of pre-rigor salting level (0-4% NaCl concentration) on physicochemical and textural properties of pre-rigor chicken breast muscles. The pre-rigor chicken breast muscles were de-boned 10 min post-mortem and salted within 25 min post-mortem. An increase in pre-rigor salting level led to the formation of high ultimate pH of chicken breast muscles at...
To evaluate the effect of salinity (S) and vermicompost (V) on yield and concentration of nitrogen (N), phosphorus (P), potassium (K), iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), calcium (Ca), magnesium (Mg), sodium (Na) and chlorine (Cl) of spinach shoots cv. Virofly, a pot experiment was conducted in greenhouse, and arranged as factorial in a completely randomized design with three rep...
The method of solute permeability coefficient and solute fluxes appointment for the membrane, based on monitoring of changes of conductivity of electrolyte solutions was presented. It was stated that during mechanical stirring of solutions the coefficient of NaCl permeability for microbial cellulose membrane (Biofill) did not depend on configuration of the membrane system and concentrations of ...
Activation of ENaC by AVP contributes to the urinary concentrating mechanism and dilution of plasma.
Arginine vasopressin (AVP) activates the epithelial Na(+) channel (ENaC). The physiological significance of this activation is unknown. The present study tested if activation of ENaC contributes to AVP-sensitive urinary concentration. Consumption of a 3% NaCl solution induced hypernatremia and plasma hypertonicity in mice. Plasma AVP concentration and urine osmolality increased in hypernatremic...
