Thermochromism Thermochromism refers to the phenomenon of color changes by the agency of heat. Obviously‚ the color changes are made possible by the temperature-induced chemical or physical changes of materials incorporated into the inks. Sometimes‚ the color change occurring at a temperature is permanent‚ and at other times the original color can be regained on cooling. Accordingly‚ we have an irreversible or reversible thermochromic system. The required chemistry can be adopted based

We have previously shown that an AR/EGFR autocrine loop is required for SUM149 human breast cancer cell proliferation‚ motility and invasion. We also demonstrated that AR

In general the functional domains include an N-terminal domain (NTD)‚ a DNA-binding domain (DBD)‚ a short hinge region‚ and a COOH-terminal domain that contains the ligand-binding domain (LBD) (Dehm & Tindall‚ 2007). The LBD is where the ligand androgen binds to
