Relationships correlating the damage expected from radiation exposure in space mission with radiobiological reactions of the body, parameters of radiation environment along the trajectory, and shielding properties of spacecraft structures were established with the use of mathematical tools of the set theory and the theory of chances. To this end, appropriate mathematical formulas were introduced which aided formalization of the space crew radiation safety task in the form of two inequalities.

Background: Recent preclinical studies have revealed a significant reduction in amyloid-β plaques and pro-inflammatory cytokines in Alzheimer's disease (AD) mouse models following low-dose radiation therapy (LDRT). This phase II, multicenter, prospective, single-blinded, randomized controlled trial (NCT05635968, funding from Korea Hydro & Nuclear Power: Grant No. A21IP11) aims to investigate the efficacy and safety of whole-brain LDRT in patients with AD.

Background: Trans-radial coronary angiogram (TR-CAG) has gained popularity due to lower complication rates compared to transfemoral access. Operators can use either conventional catheters, such as Judkins, or single dedicated catheters, such as Tiger-II. This meta-analysis compared the safety and efficacy of Tiger-II versus Judkins catheters in TR-CAG.

Rechallenge with immune checkpoint inhibitors (ICI) shows promise in various cancers, but data in esophageal squamous cell carcinoma (ESCC) is limited. This study aimed to evaluate the efficiency and safety of ICI rechallenge in ESCC. This multicenter study analyzed ESCC patients rechallenged with ICI from January 2020 to March 2023 across two medical institutions.

Objective: To test the safety and efficacy of combination treatment for pleural mesothelioma (PM) with intracavitary cisplatin-fibrin (cis-fib) plus hemithoracic irradiation (IR) applied after lung-sparing surgery in an orthotopic immunocompetent rat model.
Methods: We randomized male F344 rats into 5 groups: cis-fib (n = 9), 10 Gy IR (n = 6), 20 Gy IR (n = 9), cis-fib+10 Gy IR (n = 6), and cis-fib+20 Gy IR (n = 9). Subpleural tumor implantation was performed on day 0 with 1 million syngeneic rat mesothelioma cells (IL45-luciferase).
