Condom access in South African schools: law, policy, and practice.

Juliana Han and Michael L. Bennish discuss their experience developing a policy on condom distribution for Mpilonhle, a South African nongovernmental organization involved in HIV prevention in schools.

The BRCA1-associated protein BACH1 is a DNA helicase targeted by clinically relevant inactivating mutations.

BACH1 is a nuclear protein that directly interacts with the highly conserved, C-terminal BRCT repeats of the tumor suppressor, BRCA1. Mutations within the BRCT repeats disrupt the interaction between BRCA1 and BACH1, lead to defects in DNA repair, and result in breast and ovarian cancer. BACH1 is necessary for efficient double-strand break repair in a manner that depends on its association with BRCA1.
