Breast cancer is a significant health challenge worldwide, and disproportionately affects women of African ancestry (AA) who experience higher mortality rates relative to other racial/ethnic groups. Several studies have pointed to biological factors that affect breast cancer outcomes. A recently discovered stromal cell population that expresses P ROCR, Z EB1 and P DGFRα (PZP cells) was found to be enriched in normal healthy breast tissue from AA donors, and only in tumor adjacent tissues from donors of European ancestry (EA).

The pressing necessity to mitigate climate change and decrease greenhouse gas emissions has driven the advancement of heterostructure-based photocatalysts for effective CO₂ reduction. This study introduces a novel heterojunction photocatalyst formed by integrating potassium-doped polymeric carbon nitride (KPCN) with metallic Zn₃N₂, synthesized via a microwave-assisted molten salt method. The resulting Schottky contact effectively suppresses the reverse diffusion of electrons, achieving spatial separation of photogenerated charges and prolonging their lifetime, which significantly enhances photocatalytic activity and efficiency.

Article Synopsis
- Recent studies propose a specific phenotype of idiopathic pulmonary arterial hypertension (IPAH) in smokers characterized by low carbon monoxide diffusion capacity without major emphysema.
- The study recruited patients across four groups to investigate pulmonary capillary loss as a possible cause, utilizing advanced imaging techniques like CT and Xe MRI.
- Results revealed significant reductions in specific imaging metrics in patients with IPAH and low diffusion capacity, supporting the hypothesis of pulmonary capillary loss and potential early emphysema changes.

Context: In recent years, rechargeable batteries have received considerable attention as a way to improve energy storage efficiency. Anodic (negative) electrodes based on Janus two-dimensional (2D) monolayers are among the most promising candidates. In this effort, the adsorption and diffusion of these Li, Na, and Mg ions on and through Janus 2D-TiSSe as anodic material was investigated by means of periodic DFT-D calculations.
