A database for oncological research and quality assurance: implementation and first experiences with the University Clinical Cancer Registry Regensburg.

Legal requirements, certification specifications, as well as the demand for real world data on cancer research and treatment led to the decision to establish the University Clinical Cancer Registry Regensburg. The first organizational step in the implementation process of this oncological data registry was the evaluation and acquisition of suitable tumor documentation and database software. For this purpose, an evaluation matrix comprising required database software criteria was designed and consented by a multidisciplinary group of experts.

P2 receptors are involved in the mediation of motivation-related behavior.

The importance of purinergic signaling in the intact mesolimbic-mesocortical circuit of the brain of freely moving rats is reviewed. In the rat, an endogenous ADP/ATPergic tone reinforces the release of dopamine from the axon terminals in the nucleus accumbens as well as from the somatodendritic region of these neurons in the ventral tegmental area, as well as the release of glutamate, probably via P2Y(1) receptor stimulation. Similar mechanisms may regulate the release of glutamate in both areas of the brain.
