Sherlock Holmes and the Neurophysiologists: Unraveling the "Mystery" of Active Learning Success.

The Sherlock Holmes (SH) Project is a collaborative problem-solving activity in the form of a murder mystery that is a great resource for upper-level undergraduate courses in neurophysiology that emphasize synaptic transmission and neuromuscular communication. This project, originally described by Adler and Schwartz (2006), has become a central focus of the Neurophysiology course at Allegheny College, along with many complementary activities that work to reinforce the neuroscience material and skills such as creative experimental design and analysis. Active Learning research in advanced levels of undergraduate courses is rare in the pedagogy literature, and this paper adds to that body of research.

Structural basis for partial agonism in 5-HT receptors.

Hyperactivity of serotonin 3 receptors (5-HTR) underlies pathologies associated with irritable bowel syndrome and chemotherapy-induced nausea and vomiting. Setrons, a class of high-affinity competitive antagonists, are used in the treatment of these conditions. Although generally effective for chemotherapy-induced nausea and vomiting, the use of setrons for treating irritable bowel syndrome has been impaired by adverse side effects.
