Brown carbon (BrC) components of biomass burning organic aerosol (BBOA) absorb sunlight at visible wavelengths. However, it is not clear whether the total light absorption of this BrC is simply the sum of the contributions of the individual components or whether the components can bind noncovalently to give additional absorption through charge transfer. Here, intermolecular interactions between guaiacol and quinones (1,4-benzoquinone and 1,4-naphthoquinone) were identified in proxies of the...

CONCLUSIONS: In patients with AF and stable CAD, OAC monotherapy reduced the risk of major bleeding, with no significant differences in NACE, major ischemic events, or all-cause mortality as compared to DAT.

The ovary is a crucial gonadal organ that supports female reproductive and endocrine functions. Ovarian aging can result in decreased fertility and dysfunction across multiple organs. Research has demonstrated that cellular senescence in various cell types within the ovary can trigger a decline in ovarian function through distinct stress responses, resulting in ovarian aging. This review explores how cellular senescence may contribute to ovarian aging and reproductive failure. Additionally, we...

CONCLUSIONS: A favorable environment during adolescence provides a foundation for positive health behaviors. Interventions aimed at improving contraceptive use in young adulthood should consider creating supportive environments for adolescents.

CONCLUSIONS: The AltaValve system shows promising early procedural and clinical results for the unique anatomy of patients with atrial functional mitral regurgitation. Long-term clinical studies to demonstrate the benefit of this system are warranted.
