Calcium requirements for

Factors I, II, III, V, VII, VIII, IX, X, XI, XII, and XIII, Protein C, and Protein S are synthesized in the Hver. Factor III is present in many different organs throughout the body. Factor IV is the divalent cation calcium. The concentration of calcium required for normal function of the blood coagulation system is much less than required for normal physiologic function of many organs in the body, eg, myocardium. 

As the Kawasaki research team mentioned earlier nave concluded, there is also, with calcium, a Ca/S requirement as with the REM S for total MnS substitution 32), They have proposed the most reliable estimate so far of retained calcium requirement for "homogeneous sulfide shape control" which is summarized in Table IV and Figure 17.

The response to signaling is also shown in a progressive way. Keratinocytes grown in a low-calcium media proliferate. Increased extracellular Ca2+ inhibits proliferation, while it induces differentiation.11 On the other hand, differentiation of keratinocytes causes a decrease in responsiveness to extracellular calcium, which may facilitate the maintenance of the high level of intracellular calcium required for differentiation.12...

Enough experimental evidence has accumulated over the past few years to make a compelling case for the involvement of calcium ion in the generation of NO in various tissues and organs. The first demonstration of a calcium requirement for in vitro expression of NOS catalytic activity came from the studies by Knowles et al. (1989), using both the L-citrulline and cGMP assays. Subsequently, these results have been confirmed by many laboratories (Bredt and Snyder, 1990 Forstermann et al., 1991a Mittal,... 

The normal calcium requirements for the adult human are 0.5 g a day. However, in order to guarantee an adequate calcium balance, it is safer to include 1 to 1.2 g of calcium in the daily diet. Obviously, the... 

When considering the cellular antigen stimulation and basophil activation tests, an interesting point to bear in mind is the sensitivity of CD63 expression to external Ca concentrations compared to the calcium requirement for LTC4...
