Simultaneous spatial and temporal measurement of the concentration of the tracer in the living human body is possible with the non-invasive PET technique. Novel PET tracers for EGFR-TK will allow for the measurement of the level of expression of these macromolecules in vivo in cancer. Such data will enable better decisions in regard to patient therapeutic course of action, and open up research opportunities in cancer research and in anticancer drug development. These compounds were evaluated in vitro and in vivo. PET study of the leading tracer was performed on tumor bearing nude mice.
PET tracers are currently under study.
This simple and reliable automated procedure was routinely used in our laboratory in the last six months. Time activity curve was successfully drawn for this brain region. This condition was compared with other mental setups evoked by noisy, nature and talkshow audiovisual clips. Immediately after each clip, the participants answered three questions pertaining to what extent they thought about sex, felt aroused and sensed an erection. They scored their answers using a 1 to10 scale.
