Morphine increases acetylcholine release in the trigeminal nuclear complex.

Study Objectives: The trigeminal nuclear complex (V) contains cholinergic neurons and includes the principal sensory trigeminal nucleus (PSTN) which receives sensory input from the face and jaw, and the trigeminal motor nucleus (MoV) which innervates the muscles of mastication. Pain associated with pathologies of V is often managed with opioids but no studies have characterized the effect of opioids on acetylcholine (ACh) release in PSTN and MoV. Opioids can increase or decrease ACh release in brainstem nuclei.

Application of High-Resolution Semiconductor Detectors in X-ray Emission Spectrography.

Solid-state devices developed primarily for nuclear gamma spectroscopy have many potential uses in x-ray analysis.
