Molecular Oncology, EarlyView.Overexpression of CHRDL2 in colon cancer cells makes them more stem‐like and resistant to chemo‐ and radiotherapy. CHRDL2‐high cells have upregulation of the WNT pathway, genes involved in the DNA damage response (DDR) pathway and epithelial‐to‐mesenchymal transition (EMT). This leads to quicker repair of damaged DNA and more cell migration.

Measurement and Protection of Induced Radioactivity in Proton Heavy Ion Accelerator Therapy
Journal of Isotopes, 2021 Proton-heavy ion therapy is internationally recognized as the most advantageous radiotherapy method in oncology. However, due to the relatively high energy of the proton-heavy ion beams, the secondary neutrons produced in the process of beam energy loss ...

Thoracic radiation therapy: dosage and techniques [PDF]
Lung Cancer, 1989 Combination chemotherapy (CC) deserves credit for the increase in survival for patients with limited small cell lung cancer (SCLC). However, the best CC is not clearly established. The definition of limited disease and the work-up to define limited disease has evolved over the last 20 years.

High Efficiency Positron Accumulation for High-Precision Measurements
, 2014 Positrons are accumulated within a Penning trap designed to make more precise measurements of the positron and electron magnetic moments. The retractable radioactive source used is weak enough to require no license for handling radioactive material and ...

Molecular Oncology, EarlyView.In thyroid cancer patients, high‐dose (≥7.4 GBq) radioactive iodine therapy (RAIT) was associated with a higher prevalence of clonal hematopoiesis (variant allele frequency >2%) in individuals aged ≥50 years (OR = 2.44). In silico analyses showed that truncating PPM1D mutations conferred a selective advantage under these conditions.
