The mitogen activated protein kinases (MAPKs) have been classified into at least six subfamilies, among which ERK1/2, JNK1/2 and p38 MAPK are the most extensively studied. The steroid hormones 1alpha,25-dihydroxy-Vitamin D(3) and 17beta-estradiol promote biological responses through activation of MAPK cascades in various cell types. We previously reported(More)
A new design for a true-linear generator suitable for electrochemical measures is presented. The main component of generation system is an MAX038 chip, a high-frequency relaxation-type oscillator. The design is completed with a digital interface for computer control and an output stage to make signal suitable for cyclic voltammetry experiments. A digital(More)
In this paper a system is described for impedance measurements in electrochemical cells, integrated by a fast potentiostat, signal generator, digital transient recorder and a computer interface. The treatment of the signal is made by obtaining the correlation between the response cell signal with the in-phase and in-quadrature signals, as is made in the(More)
