Monitoring radiofrequency renal lesions in real time using contrast-enhanced ultrasonography: a porcine model.

abstract：BACKGROUND AND PURPOSE:Magnesium (Mg(2+)) has been shown to be a kidney stone inhibitor; however, the exact mechanism of its effect is unknown. Using theoretical models, the interactions of calcium and oxalate were examined in the presence of Mg(2+). METHODS:Molecular dynamics simulations were performed with NAMD and ...
