SLU scientist examines potential biomarkers for pain linked to debilitating health conditions

With new funding from The Mayday Fund, a Saint Louis University researcher will leverage her discovery of a pain pathway to determine if either of two key molecules can be used as biomarkers for pain associated with four debilitating health conditions: chemotherapy-induced peripheral neuropathy, endometriosis, interstitial cystitis and vulvodynia.

Researchers explore role played by nicotine in grouping of nicotinic receptors within the brain

Nicotine -- the primary compound found within tobacco smoke -- is known to change the grouping of some subtypes of nicotinic receptors, but the mechanisms for nicotine addiction remain unclear.

Study confirms that cocaine makes users more willing to partake in risky sex

Cocaine use has long been tied anecdotally to higher-than-usual rates of impulsive behavior, including risky sex, but the tie-in has been difficult to study with any scientifically controlled rigor.

Nicotine creates cascade of effects in the brain that get worse over time

The first period of nicotine abstinence proceeded as expected. The surprise came after three months when the lab rats suddenly became fearless and sought out well-lighted areas that prey animals normally avoid. At the same time, signaling in the brain's reward system changed, as shown by a study at Sahlgrenska Academy.
