Characterization of a typical urban soil in terms of natural radionuclide content. The case study of a university campus

Heliyon
A first comprehensive survey was carried out in a university campus in Italy in order to investigate in terms of natural elements an area where medium-high values of natural radiation are expected because of its peculiar geological features.

Targeting Tumor Stroma: Current Challenges and Future Directions

MedComm, Volume 7, Issue 5, May 2026.
Figure 1. Mechanism of ECM reprogramming. Cancer‐associated fibroblasts (CAFs), cancer‐associated macrophages (CAMs), and other mesenchymal cells alter the ECM composition and increase its stiffness by depositing matrix components such as collagen and hyaluronic acid, and secreting cross‐linking agents like lysyl oxidase homolog 2 (LOXL2).

Aptamer‐Functionalized Nanocarriers for Bone and Joint Diseases: Engineering Design Rules and Translational Roadmap

Small Science, Volume 6, Issue 5, -Not available-.
Aptamer‐functionalized nanocarriers represent a versatile platform for targeted therapy in bone and joint diseases. This review presents five complementary design strategies: free aptamers for soluble targets, bispecific multivalent constructs for enhanced avidity, nanoparticle‐conjugated aptamers for selective tissue accumulation, aptamer‐based ...

The Influence of Bedding Orientation and Temperature on the Creep Behavior of Opalinus Clay

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The time dependency of deformation is of critical concern for assessing the integrity of barriers in nuclear waste repositories. Creep, in particular, is a phenomenon recognized for its potential “self‐sealing” properties or, conversely, the potential for delayed failure in the rock mass surrounding an excavation.
