Once thought to be 8 billion years old, the star HD 110067 — famous for its six synchronized exoplanets — may be only 2.5 ...

Investigations. Measurement of levels of serum phosphate, parathyroid hormone, ionized calcium and insulin; measurement of peak growth hormone by the arginine–levodopa stimulation test ...

This test measures the overall amount of calcium in the blood, including free (ionized) calcium and the calcium bound to proteins. It provides a general overview of calcium levels and is often ...

Unbound calcium is not attached to a protein. It's the active form of calcium, called free or ionized calcium. In most cases, a total calcium blood level is ordered. In specific scenarios ...

Serum ionized calcium (SiCa ++), total and albumin adjusted calcium and intact paratharmone (iPTH) were measured at eight points covering menstrual, immediate post-menstrual, mid-cycle and ...

Calcimimetics suppress secretion of parathyroid hormone (PTH) by increasing the sensitivity of the calcium receptors of parathyroid cells to extracellular ionized calcium. As the activity of drugs ...
