Recently, scientific publishing has experienced an expansion of journals and publishers whose primary goal is profit and whose peer review process is virtually non-existent. These “predatory” or “opportunistic” journals pose a threat to the credibility and integrity of legitimate scientific literature, and quality science. Unfortunately, many scientists choose to publish in these journals and/or serve on their editorial boards, either due to ease of rapid publication or naivety. Here, we highlight the extensive use of predatory publications or editorial board involvement by applicants applying for a faculty position in the Pharmaceutical Sciences department at the Bill Gatton College of Pharmacy at East Tennessee State University. We caution search committees at other pharmacy schools to thoroughly examine applicant curricula vitarum (CVs) for predatory publishing.

OBJECTIVE: Methylphenidate is commonly used in the treatment of Attention Deficit Hyperactivity Disorder and narcolepsy. Methylphenidate is administered as a racemic mixture of the d- and l- threo enantiomers; however, the d-enantiomer is primarily responsible for the pharmacologic activity. Previous studies of the behavioral effects of methylphenidate have highlighted sex differences in the responsiveness to the drug, namely an increased sensitivity of females to its stimulatory effects. These differences may be due to differences in the uptake, distribution, and elimination of methylphenidate from male and female brains. Therefore, we compared the pharmacokinetics of d- and l- threo methylphenidate in the brains of male and female rats. MATERIALS AND METHODS: Adult male and female Sprague-Dawley rats were injected with 5 mg/kg d, l- threo methylphenidate, and whole brains were collected at various time points following injection. We measured methylphenidate concentrations utilizing chiral high pressure liquid chromatography followed by mass spectrometry. RESULTS: Females exhibited consistently higher brain concentrations of both d- and l- methylphenidate and a slower clearance of methylphenidate from brain as compared to males, particularly with the active d-enantiomer. CONCLUSIONS: The increased sensitivity of females to methylphenidate may be partially explained by an increase in total brain exposure to the drug.
