Structural and ion-ordering phase transitions limit the viability of sodium-ion intercalation materials in grid scale battery storage by reducing their lifetime. However, combination phenomena nanoparticulate electrodes creates complex behavior that is difficult to investigate, especially on single-nanoparticle under operating conditions. In this work, operando single-particle X-ray diffraction...

BACKGROUND The average dietary sodium intake of Koreans is 2.6 times higher than the World Health Organization's recommended amount. The effect of a diet high in sodium on the skeletal system, especially osteoporosis, has not previously been examined in Korean postmenopausal women with low bone mass. We assessed the daily sodium intake, and determined the impact of sodium intake on urinary calc...

It has been reported that calcium intake may effectively modulate the expression of hypertension affected by sodium. The present study extends our previous analysis of this calcium-sodium interaction, additionally demonstrating that calcium, sodium, and alcohol intake further contribute to both systolic and diastolic blood pressures in normotensive subjects. Calcium intake was related to lower ...

Experiments were performed on the lobster giant axon to determine the relation between intracellular spike amplitude and external calcium ion concentration. Action potential decline in low external calcium is greatly accelerated by simultaneous removal of external sodium ion. Correlation of the time course of spike decline in low calcium-low sodium solution with the time courses of spike declin...

In this study, a gel/liquid interface is utilized for growing new (calcium-phosphate)/carrageenan garden. The hydrogels are made from carrageenan loaded with either sodium phosphate or calcium chloride, while the interfaced solution contains source of salt not used in (i. e. sodium-phosphate hydrogel calcium-chloride and vice versa). physical chemical properties tubes grown both systems same am...

The functionality of bare polylactide-co-glycolide (PLGA) nanoparticles is limited to drug depot or drug solubilization in their hard cores. They have inherent weaknesses as a drug-delivery system. For instance, when administered intravenously, the nanoparticles undergo rapid clearance from systemic circulation before reaching the site of action. Furthermore, plain PLGA nanoparticles cannot dis...

pure submandibular saliva was collected from anaesthetized vitamin - a - treated and control rats with using of pilocarpine as secretogogue, and then the serum was collected by cardiac puncutre. intraperitoneal injection of a large single dose (100,000 iu/kg) of vitamin a changed total protein, calcium and sodium concentrations of saliva so that sodium level of submandibular saliva was reduced ...

Eight normotensive subjects were studied in a randomized crossover trial of a high calcium diet (1800 mg of calcium/day) for a week against a low calcium diet (200 mg of calcium/day) for a further week. The subjects were placed on a diet containing 200 mg of calcium/day throughout the study and the high calcium diet was achieved by supplementing the low calcium diet with calcium glubionate and ...

BACKGROUND The results of the studies on the effects of sodium on bone metabolism have been inconsistent. There is no definitive answer to the question of whether sodium restriction can be associated with a lower incidence of osteoporosis. What reinforces the necessity of designing this study is the lack of findings with the approach of examining the effects of sodium on bone in our country. ...
