Transgender Women Exhibit a Distinct Stress Echocardiography Profile Compared With Age-Matched Cisgender Counterparts: The Mayo Clinic Women's Heart Clinic Experience.

Background: Stress echocardiographic (SE) testing is an important modality in cardiovascular risk stratification and obstructive coronary artery disease assessment. Binary sex-based parameters are classically used for the interpretation of these studies, even among transgender women (TGW). Coronary artery disease is a leading cause of morbidity and mortality in this population.

Advanced Photosensitizer Activation Strategies for Smarter Photodynamic Therapy Beacons.

Photodynamic therapy (PDT) is a clinical treatment in which a light-absorbing drug called a photosensitizer (PS) is combined with light and molecular oxygen to generate cytotoxic singlet oxygen. PDT provides additional tissue selectivity compared to conventional chemotherapy as singlet oxygen is generated only in areas in which PS accumulates and that are simultaneously illuminated by a light source with sufficient irradiance and dose. Early PDT beacons built on this concept by adding an analyte-responsive element that simultaneously turns on PDT and fluorescence, providing both an additional layer of selectivity and real-time feedback of the PS's activation state.
