Mouse model reveals potential way to reduce cardiac deaths in kidney patients
...cification. The body normally takes minerals like calcium and phosphorous circulating in the bloodstream and deposits them in the bones during bone reconstruction. With those processes shut down, scientists theorized, the bloodstream levels of minerals increase, raising pressure to deposit them elsewhere. ...Some brain cells 'change channels' to fine-tune the message

... treatment. The newer treatment strategy using the calcium channel blocker, amlodipine, and the angiotensin converting enzyme inhibitor, perindopril was compared with the older treatment strategy based on the beta-blocker, atenolol and the thiazide diuretic, bendroflumethiazide.
