OBJECTIVE To study the possible effects of methanolic extract of fruits of Tamarindus indica on rabbit's jejunum preparations. MATERIALS AND METHODS The study was carried out on rabbit's jejunum preparations. Methanolic extract of fruits of T. indica was applied in different doses. Potassium chloride (KCl 80 mM)-induced contractions were relaxed by the extract. For determination of possible m...

For vertebrate olfactory signal transduction, a calcium-activated chloride conductance serves as a major amplification step. However, the molecular identity of the olfactory calcium-activated chloride channel (CaCC) is unknown. Here we report a proteomic screen for cilial membrane proteins of mouse olfactory sensory neurons (OSNs) that identified all the known olfactory transduction components ...

In the study the effect was assessed of sample processing with solutions containing inhibitors of enzymatic browning and tissue softening and sucrose on the quality of minimally processed apples. Ascorbic acid, citric acid, 4-hexylresorcinol, sodium chloride, calcium chloride, sodium lactate, calcium lactate and sucrose were used as inhibitors. The application in apple slice processing of a sol...

GABA excites immature neurons due to their relatively high intracellular chloride concentration. This initial high concentration is commonly attributed to the ubiquitous chloride cotransporter NKCC1, which uses a sodium gradient to accumulate chloride. Here we tested this hypothesis in immature retinal amacrine and ganglion cells. Western blotting detected NKCC1 at birth and its expression firs...

Commercial tetraethylammonium chloride contains about 5% of the impurity triethylamine. External triethylamine raises cytoplasmic pH, which reduces the intracellular calcium concentration transient following calcium influx during membrane depolarization. The calcium influx is unaffected, so the cell's ability to buffer calcium transients is reduced. Purified tetraethylammonium does not have the...

Chloride transport proteins play critical roles in inflammatory airway diseases, contributing to the detrimental aspects of mucus overproduction, mucus secretion, and airway constriction. However, they also play crucial roles in contributing to the innate immune properties of mucus and mucociliary clearance. In this review, we focus on the emerging novel roles for a chloride channel regulator (...

this experiment was carried out to study the effect of sodium chloride from drinking water and feed intake on the quality of egs from laying hens. four hundred and twenty native and white leghorn laying hens ranging from 36 to 43 weeks of age were used. seven experimental treatments containing different levels of salt supplied by feed and/or drinking water were compared. increasing salt int...

this study examined the influence of pre-frying treatments and oil type on the moisture outflow and oil uptake during the frying of potato strips. the pre-treatments were 6 min blanching in a 85°c a water bath containing 0.5% calcium chloride and immersion in a 1% solution of carboxymethyl cellulose; 6 min blanching in a 85°c water bath containing 0.5% calcium chloride and immersion in a 2% sol...
