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
...short, that help replace channels that let charged calcium
ions in with another kind of channel that keeps calcium
out. If muscle-controlling nerve cells can do the same thing, forcing the swap might help protect th...
Blood pressure treatment could cut risk of strokes and heart attacks
... 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. ASCOT study co-chairmen Peter...
Student identifies electrical changes preceding heart failure

levels in the individual tissue samples. The emitted light was then collected by a sensitive optical detection system, converted to current and stored on a computer for analysis. Hahn and Akar were able to demonstrate that electrical disturbances occ...
History of broken bones overlooked when treating osteoporosis
...s International. Bone density tests show how much calcium
is in the bones, but fracture history is also valuable in giving a more complete picture, Dr. Siminoski said. "In a way, these people have tested their own bones and shown they have a tendency to break." Bone densitometry has been widely available f...
Infectious microorganism linked to kidney stones and other diseases
... discovered in the 1990s and has been found in the calcium
phosphate centers of kidney stones. This novel agent has also been detected in related conditions, including Alzheimer's disease, heart disease, prostatitis, and some cancers. Further testing for the presence of NB in human bodies can help reduce t...

Milk, fruits and vegetables may help reduce disability risk
