Prevention of future incidents and investigational lines.

All radiation devices in use nowadays are subject to cause serious incidents and accidents, with potential risks in exposed population groups. These risks may have immediate or long term health implications. The detection of radioactive incidents is a procedure that should be systematized in economically developed societies.

VIP and PACAP receptors coupled to adenylyl cyclase in human lung cancer: a study in biopsy specimens.

Vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) are important neuropeptides in the control of lung physiology. Both of these commonly bind to specific G protein coupled receptors named VPAC(1)-R and VPAC(2)-R, and PAC(1)-R (with higher affinity for PACAP). VIP and PACAP have been implicated in the control of cell proliferation and tumor growth.
