The difference amplifier shown in Figure 27.8 is a basic amplifier block that can be extended to measure very small signals differentially in the body. Such measurements are the basis behind common connected health signal-acquisition targets such as the electrical activity of the heart (EKG/ECG), those of the muscles (EMG), and that... 

In this text a theoretical and practical introduction is given for anyone interested in applying derivative spectrophotometry — or other multidifferentiation techniques - to analytical studies. In particular, the various modes of instrumentation for signal differentiation are described and critically compared to point out the advantages and drawbacks of the various methods and to reveal common difficulties.

Alternating-current amplifiers generally do not perform well at low frequencies (< 10 Hz) and exhibit signal phase shift or signal differentiation. High-frequency response must be selected so that risetime is not compromised for the signals being processed. On the other hand, ac amplifiers provide stable operation, are relatively free from baseline drift, and require much less calibration than dc amplifiers. 

Src family kinases, one genre of PTKs, play an important role in the regulation of normal cellular signal transduction pathways, such as cell division, growth factor signaling, differentiation, survival, adhesion, migration, and invasion [64]. Src mutations and/or overexpression had been correlated with tumor growth.
