Breast cancer outcomes in women with ovarian cancer and a pathogenic germline BRCA mutation.

Background: Women with ovarian cancer (OC) and a pathogenic variant in the BRCA1 or BRCA2 genes are at increased risk of developing breast cancer (BC). Evidence for long term outcomes in these patients who undergo bilateral risk reduction mastectomy (RRM) after ovarian cancer is sparse. The aim of this study was to analyse the long-term breast cancer-related outcomes of patients who have been diagnosed with ovarian cancer and found to have BRCA1 or 2 pathogenic variants.

Elucidating the Discharge Behavior of Aqueous Zinc Sulfur Batteries in the Presence of Molybdenum(IV) Chalcogenide Catalyst: The Criticality of Interfacial Electrochemistry.

The aqueous zinc-sulfur battery holds promise for significant capacity and energy density with low cost and safe operation based on environmentally benign materials. However, it suffers from the sluggish kinetics of the conversion reaction. Here, we highlight the efficacy of molybdenum(IV) sulfide (MoS) to reduce the overpotential of S-ZnS conversion in aqueous electrolytes and study the discharge products formed at the solid-solid and solid-liquid interfaces using experimental and theoretical approaches.

Subsurface microbial community structure shifts along the geological features of the Central American Volcanic Arc.

Subduction of the Cocos and Nazca oceanic plates beneath the Caribbean plate drives the upward movement of deep fluids enriched in carbon, nitrogen, sulfur, and iron along the Central American Volcanic Arc (CAVA). These compounds fuel diverse subsurface microbial communities that in turn alter the distribution, redox state, and isotopic composition of these compounds. Microbial community structure and functions vary according to deep fluid delivery across the arc, but less is known about how microbial communities differ along the axis of a convergent margin as geological features (e.
