solutions containing different concentrations of oxaloacetat

Did you see some real peaks with the oxaloacetate and malate or was it rather shifted baseline? (especially in the case of 1:10 dilution) As you can see, the absorbance of oxaloacetate and malate in range 4 - 0.8 mM is rather low if any. On the other hand, NADH absorbs ...

The Heart

... SNS. The PNS is associated with autonomic functions (so ones we don't think about like breathing in and out) and via the vagus nerve controls the baseline heartrate of about 60-80. However during exercise etc. this needs to speed up to supply more oxygen and at this point a sympathetic function ...

Negative concentration??

You can see, that theoretically, if your concentration was zero (x = 0 ng/ml), than you wil get absorbance of 0.1235. That means, that you have bad baseline (that is, your blank sample is actually not blank, but absorbs), but more likely Excel just found the best fit, which just starts a little ...

multiple myeloma survival

... and symptom combinations, different stages at diagnosis, probably some numbers associated with different treatments. It is hard to find "baseline" numbers, though.

How does a cell know how big it is?

This is just a guess, but how about the concentration of some intracellular signalling molecule? If a cell has a baseline production of some such protein, it would then stop synthesizing cell membrane when the concentration of that molecule falls below a level that would trigger ...
