Sorption and Migration of Radionuclides in Geologic Media [PDF]

, 1979
The interactions of a quartz monzonite, an argillite, an alluvium, and several tuffs with various radionuclides in selected phreatic waters has been studied. The sorption-desorption behavior of Sr, Tc(VII), Cs, Ba, Ce, Eu, U(VI), Pu, and Am under ambient and 70°C temperature conditions has been measured.

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 ...

Transcriptional Profiling of Growth Hormone–Secreting Pituitary Adenoma Stem‐Like Cells: Unveiling the Significant Role of CXCR4 in Tumorigenesis and Clinical Applications

MedComm, Volume 7, Issue 9, September 2026.
Growth hormone–secreting pituitary adenomas harbor hPASCs (human pituitary adenoma stem‐like cells). Genetic profiling of hPASCs identified CXCR4 as a significant gene orchestrating a regulatory network in the self‐renewal and differentiation of hPASCs, as well as the modulation of tumor cells and the microenvironment.

Preserved Through Hyperaridity, 150 Million Years of Exhumation and Strike‐Slip Deformation in the Atacama Coastal Cordillera

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The Coastal Cordillera of northern Chile, in the forearc of the Andean subduction zone, provides an ideal site to evaluate exhumation above the oldest active subduction under extreme aridity. This range lies parallel to a sediment‐starved trench, has experienced hyperaridity since the Miocene, and is transected by the ∼1,000‐km‐long Atacama ...

Structural Responses of Aluminoborosilicate Glasses to Pressure and Iodine Incorporation: An Advanced NMR Investigation

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
Pressure densifies the glass network and enhances iodine retention, while iodine promotes local repolymerization of the silicate network. ABSTRACT Iodine‐129 is a critical challenge for nuclear waste immobilization due to its high mobility and extremely long half‐life (1.57 × 107 years).

Integrating Multiple Approaches to Reveal the Spatiotemporal Pattern of Soil Erosion in Mollisol Watershed

Land Degradation &Development, Volume 37, Issue 14, Page 10355-10370, 30 August 2026.
ABSTRACT Although numerous prediction methods have been developed, scientific estimation of the spatiotemporal pattern of soil erosion at the watershed scale remains challenging. In this study, fallout radionuclides of 210Pbex and 137Cs were used to estimate average annual soil erosion and deposition in a Mollisol watershed in Northeast China ...
