Repeated nicotine vapor inhalation induces behavioral sensitization in male and female C57BL/6 mice.

Electronic cigarette use has significantly increased over the past decade. However, there is limited preclinical research on the behavioral and abuse-related effects of nicotine vapor inhalation in rodents. The present study evaluates the effects of repeated nicotine vapor inhalation in male and female mice using a nicotine behavioral sensitization model.

Characterization and comparative performance of lentiviral vector preparations concentrated by either one-step ultrafiltration or ultracentrifugation.

Gene therapy utilizing lentiviral vectors (LVs) constitutes a real therapeutic alternative for many inherited monogenic diseases. Therefore, the generation of functional vectors using fast, non-laborious and cost-effective strategies is imperative. Among the available concentration methods for VSV-G pseudotyped lentiviruses to achieve high therapeutic titers, ultracentrifugation represents the most common approach.
