Results of a Formal Mentorship Program for Internal Medicine Residents: Can We Facilitate Genuine Mentorship?

Background: Mentorship programs are perceived as valuable, yet little is known about the effect of program design on mentoring effectiveness.

Intervention: We developed a program focused on mentoring relationship quality and evaluated how subsequent relationships compared to preexisting informal pairings.

Methods: Faculty members were invited by e-mail to participate in a new mentoring program.

Extracytoplasmic stress responses induced by antimicrobial cationic polyethylenimines.

The ability of an antimicrobial, cationic polyethylenimine (PEI+) to induce the three known extracytoplasmic stress responses of Escherichia coli was quantified. Exposure of E. coli to PEI+ in solution revealed specific, concentration-dependent induction of the Cpx extracytoplasmic cellular stress response, ~2.

Evaluation of the antimicrobial activity of cationic polyethylenimines on dry surfaces.

The antimicrobial activity of cationic N-dodecyl-N-methylpolyethylenimine (PEI+) against S. aureus, A. baumannii, and E.
