The death and clearance of nurse cells is a consequential milestone in Drosophila melanogaster oogenesis. In preparation for oviposition, the germline-derived nurse cells bequeath to the developing oocyte all their cytoplasmic contents and undergo programmed cell death. The death of the nurse cells is controlled non-autonomously and is precipitated by epithelial follicle cells of somatic origin acquiring a squamous morphology and acidifying the nurse cells externally.

Purpose: In light of evolving evidence that some patients with node-positive estrogen receptor-positive (ER+) disease may receive less benefit from chemotherapy, this study reports 12-year outcomes of the C9741 trial overall, and by the sensitivity to endocrine therapy (SET2,3) test index, a biomarker measuring endocrine transcriptional activity, to identify patients most likely to benefit from dose-dense chemotherapy.

Methods: In all, 1,973 patients were randomly assigned to dose-dense versus conventional chemotherapy. Hazard ratios (HRs) for prognosis and for predictive interaction with chemotherapy schedule were estimated from Cox models of long-term disease-free survival (DFS) and overall survival (OS).

New Human Immunodeficiency Virus (HIV) cases continue to disproportionately burden cisgender Black/African American women in the United States due to a confluence of structural and systemic factors. Pre-exposure prophylaxis (PrEP) is a safe and effective HIV prevention option, yet there is a striking gap between PrEP eligibility and uptake among cisgender Black women. The current study evaluates a novel warm handoff process in a hospital emergency department setting linking eligible women to local PrEP clinics within 72 hours of hospital discharge in a large southwestern metropolitan city.
