Description
In recent years the abuse of synthetic cathinones, "Bath Salts," has increased. The purpose of this study was to analyze two synthetic cathinones, methylone and α-pvp, for hedonic properties or the potential to be abused. This was tested using an intracranial self-stimulation paradigm, a robust measurement for reward. It was found methylone resulted in an abuse potential similar to MDMA, ecstasy, abuse. Moreover, the results for α-pvp showed a high liability for abuse.

Description
This creative project explores the trend of designer/synthetic drug use in Arizona and nationwide. The project serves as "gap research" - bringing to light the problem of limited use statistics and constantly-changing drug chemical compounds. The project was thoroughly researched using media reports, psychology/drug addiction experts, community education organizers and available healthcare statistics. The results provided not definitive answer other than that more work needs to be done in the area of synthetic drug use. Parents and youth must educate themselves on the dangers of using these "legal" drugs.

Description
Menopause is reproductive senescence characterized by a loss of ovarian estrogen and progesterone. Women can experience cognitive decline and other negative symptoms with the loss of ovarian hormones (Sherwin, 2006). While hormone therapies (HT) can treat symptoms of menopause and may have neuroprotective properties, such as the potential to decrease the risk of Alzheimer's Disease (Behl & Manthey, 2000), there are many effects of current HTs that are not ideal. Indeed, optimizing conventional HTs has proven complex, indicating a need for alternative therapies. Phytoestrogens are estrogenic compounds found naturally in plants such as soybeans, that could provide new treatment options. Dietary phytoestrogens can benefit memory in the rodent model (Luine, 2006), although the mechanism underlying these effects is unclear. Basal forebrain cholinergic projections have been shown to mediate the cognitive benefits of estrogen (Gibbs, 2010); we hypothesize that phytoestrogens act similarly, via the cholinergic system, to impact memory. We administered varying doses of phytoestrogen-containing diets to ovariectomized female rats, and used the place recognition task to evaluate spatial memory. Brains were then analyzed for choline acetyltransferase (ChAT), the synthesizing enzyme for acetylcholine, in the vertical-diagonal bands (VDB) and the medial septum (MS) of the basal forebrain. Results showed that ChAT cell counts in the VDB were marginally higher with dietary phytoestrogen treatment. Further, VDB ChAT cell counts positively correlated with place recognition performance, indicating that animals with more VDB ChAT neurons exhibited better spatial memory performance. These results suggest that phytoestrogens might act similarly to natural, endogenously circulating estrogens, and identify phytoestrogens as a direction for investigation as a HT.
