Gamma-ray-induced attenuation in Al-doped and Al/Tm-co-doped optical fibers is investigated in the visible and near-infrared domain up to 1 Gy. The behavior of radiation-induced attenuation (RIA) regarding dose and dose rate is discussed. Our results reveal high sensitivities for both types of fibers at low gamma ray doses and also reveal that Al/Tm fibers are very promising at original interrogation wavelengths for dosimetry applications.

Ionizing radiation-induced injury often occurs in nuclear accidents or large-dose radiotherapy, leading to acute radiation syndromes characterized by hematopoietic and gastrointestinal injuries even to death. However, current radioprotective drugs are only used in hospitals with unavoidable side effects. Here, we heated the aqueous solution of inulin, a polysaccharide dietary fiber, forming colon-retentive gel as a radiation protector in radiotherapy.

In daily life, individuals are frequently exposed to various forms of radiation, which, when adhering to safety standards, typically result in relatively minor health effects. However, accidental exposure to radiation levels that exceed these safety standards can lead to significant health consequences. This study focuses on the analysis of radiation-induced damage to the nervous system and the mechanisms of pharmacological protection.

Article Synopsis
  • Ionizing radiation can cause myocardial damage, which limits the use of radiotherapy in cancer treatment.
  • Astragalus polysaccharide (APS), derived from the Astragalus herb, shows promise as a cardioprotective agent against radiation-induced heart disease (RIHD) through various molecular mechanisms.
  • Research identified key genes and pathways involved in RIHD, revealing that APS improves heart function and reduces injury and inflammation in laboratory models through enhancing autophagic processes.

Background: Primary leptomeningeal gliomatosis (PLG) is a rare neoplasm characterized by the diffuse spread of glial tumor cells throughout the leptomeninges without any evidence of a primary tumor source in the brain or spinal cord parenchyma. Here, we present a case of PLG potentially linked to prior interventional radiotherapy.

Case Description: The patient was a 75-year-old woman with a history of interventional radiology for a left internal carotid cavernous sinus fistula 13 years before presentation.
