Effective delivery and controlled release of metallo-prodrugs with sustained activation and rapid response feed the needs of precise medicine in metal chemotherapeutics. However, gold-based anticancer drugs often suffer from detoxification binding and extracellular transfer by sulfur-containing peptides. To address this challenge, we integrate a thiol-activated prodrug strategy of newly prepared hypercoordinated carbon-centered gold(I) clusters (HCGCs) with their photosensitization character to augment the mitochondrial release of Au(I) in tumors.

Background: Despite being recognised as a global problem, our understanding of human-mediated antimicrobial resistance (AMR) spread to remote regions of the world is limited. Antarctica, often referred to as "the last great wilderness", is experiencing increasing levels of human visitation through tourism and expansion of national scientific operations. Therefore, it is critical to assess the impact that these itinerant visitors have on the natural environment.

Background: Childhood obesity prevalence remains high, especially in racial and ethnic minority populations with low incomes. This epidemic is attributed to various dietary behaviors, including increased consumption of energy-dense foods and sugary beverages and decreased intake of fruits and vegetables. Interactive, technology-based approaches are emerging as promising tools to support health behavior changes.

Article Synopsis
  • Hyperacute cardiac CT is more effective than transthoracic echocardiography in detecting intracardiac thrombus, but its routine use is limited due to costs and risks.
  • A study of 1,136 ischemic stroke or TIA patients found that longer arterial input function (AIF) dispersal times correlate with the presence of thrombus and worse outcomes, with a specific cutoff of 33 seconds indicating higher risk.
  • The findings support using AIF dispersal measurements to help identify patients who may benefit from cardiac imaging, potentially optimizing resource use in stroke management.
