Branding has not traditionally been explicitly used by training programs for recruitment. However, it can be used as a powerful tool to help recruit and retain candidates who will thrive in your program.

Purpose: Sexual activity and sexually transmitted infection (STI) rates are high in adolescents. In this study, we sought to determine whether the initiation of a school-based condom availability program was associated with a decrease in STI rates.

Methods: We compared the rates of STIs in 15-19-yr-olds reported to the Massachusetts Department of Public Health for the 3 years before and after a condom availability program was introduced in Holyoke, MA, as compared with a similar city, Springfield, MA, which did not have such a program.

In Saccharomyces cerevisiae, OLE1 encodes a delta9 fatty acid desaturase, an enzyme that plays a critical role in maintaining the correct ratio of saturated to monounsaturated fatty acids in the cell membrane. Previous studies have demonstrated that (i) OLE1 expression is repressed by unsaturated fatty acids (UFAs) and induced by low oxygen tension, (ii) a component of this regulation is mediated through the same low oxygen response element (LORE) in the OLE1 promoter, and (iii) Mga2p is involved in LORE-dependent hypoxic induction of OLE1. We now report that LORE-CYC1 basal promoter-lacZ fusion reporter assays demonstrate that UFAs repress the reporter expression under hypoxic conditions in a dose-dependent manner via LORE.
