Aggressive breast cancers often fail or acquire resistance to radiotherapy. To develop new strategies to improve the outcome of aggressive breast cancer patients, we studied how PARP inhibition radiosensitizes breast cancer models to proton therapy, which is a radiotherapy modality that generates more DNA damage in the tumor than standard radiotherapy using photons. Two human BRCA1-mutated breast cancer cell lines and their isogenic BRCA1-recovered pairs were treated with a PARP inhibitor and irradiated with photons or protons.

Electrospinning a layer of polyacrylonitrile nanofibers, or nanoPAN, onto a polymer-coated silver mirror yields a total solar reflectance of 99 %, an albedo of 0.96, and a thermal emittance of 0.

Purpose: Several lung function endpoints are utilized in clinical trials of inhaled bronchodilators for chronic obstructive pulmonary disease (COPD). Trough forced expiratory volume in 1 second (FEV) is a commonly reported endpoint in COPD trials and can be complemented by area under the FEV vs time curve (FEV AUC), which provides information on duration and consistency of bronchodilation over a dosing interval. Revefenacin, a once-daily bronchodilator, significantly improved lung function in patients with COPD when measured by trough FEV in two replicate Phase 3 trials.
