Abscopal Effect in Radiation Therapy: The Immune Mechanisms and Clinical Advances

MedComm, Volume 7, Issue 9, September 2026.
The schematic outlines the key events of the abscopal effect. (Ignition) Local radiotherapy (RT) induces the release of immunogenic signals from the tumor, leading to dendritic cell (DC) activation. (Orchestration) In the tumor‐draining lymph node (TDLN), DCs prime naive T cells into cytotoxic T lymphocytes (CTLs), a process modulated by regulatory T ...

Gray Matter Microstructure Measured Using Diffusion Imaging as a Biomarker of Severity in Lewy Body Diseases

Movement Disorders, Volume 41, Issue 9, Page 2310-2324, September 2026.
Abstract Background Despite widespread cortical involvement in Lewy body diseases, conventional gray matter magnetic resonance imaging (MRI) shows limited sensitivity. Diffusion‐weighted MRI‐derived microstructural measures have shown utility in Alzheimer's disease, but their application across the Lewy body disease spectrum remains limited ...

Experimental activation assessment of open‐type yoke in a PET cyclotron by non‐destructive/destructive γ‐ray measurement approaches

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background During decommissioning of positron emission tomography (PET) cyclotron facilities, metallic components—including the iron yoke—are typically classified as radioactive waste, incurring substantial disposal costs. In contrast to concrete, standardized decommissioning procedures for metallic components have not yet been established ...

Personalization and Fortification of In‐Space Manufactured Emulsified Beverages for Long‐Term Space Travel

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...
