The vapor permeability of modified polyethylene films after long-term exposure to UV radiation and atmospheric factors was studied. The dependences of changes in diffusion characteristics on the type of modifying additiv...

Objective: To investigate the role of integrin beta-1 (Itgb1) in radiation-induced tissue injury and elucidate its underlying molecular mechanisms. Methods: Differentially expressed genes associated with radiation injury...

Abstract This cross-sectional study was conducted at Shanxi Province Cancer Hospital between July and August, 2025, using a self-administered questionnaire. A total of 523 valid questionnaires were analyzed (effective re...

Herein, the radiation patterns of single-split ring resonators (SSRRs) and double-split ring resonators (DSRRs) in the vertical direction are tailored by reconfiguring the resonator geometries. To design unequal arm leng...

Abstract In this research the absorbed dose by the thyroid gland of radioiodine 131I during treatment of the thyroid cancer after total or partial remove of the thyroid gland by operation, the radioiodine is concentrated...

Abstract Objective Occupational exposure to ionizing radiation is a known risk factor for genomic instability. This study evaluated whether physicians occupationally exposed to ionizing radiation exhibit higher frequenci...

Abstract Populations residing in high-level natural radiation areas (HLNRA) along the monazite-rich coastal belt of Kerala, India, are chronically exposed to low-dose ionizing radiation, with lifetime cumulative doses ex...

Noni fruit (M. citrifolia L.) is a medicinal plant known for its antioxidant bioactive compounds, which have potential use as radiation protection agents. Despite their traditional use, the specific bioactive compounds a...

Abstract Background Radiation-induced sarcoma (RIS) is a rare, fatal late complication of radiotherapy for nasopharyngeal carcinoma (NPC), particularly in the anatomically complex skull base region. Despite the high radi...

The tin industry in Indonesia is a major global producer, and mining and smelting processes can mobilize and concentrate Naturally Occurring Radioactive Materials (NORM), particularly radionuclides from the 238U and 232T...

Abstract Background Radiation therapy is commonly used as an adjunct to incomplete surgical excision in dogs with mast cell tumors (MCT), but the optimal dose and fractionation regimen have yet to be determined. Hypothes...

Background: The rising demand for interventional radiology procedures (IRPs) performed under fluoroscopic guidance increases the risk of harmful radiation effects for patients and staff. Radiation dose optimisation usin...

Objective: To develop an artificial intelligence (AI) driven plan tradeoff decision making assistant for radiation oncologists. Methods: A user interface (UI) was developed to integrate the assistant with the treatment p...

ABSTRACT Background and Aim The introduction of radiation in medicine has led to significant breakthroughs in diagnostic, interventional, and therapeutic practices. However, the increasing demand for medical radiation ha...

Abstract The Solar Radiation and Air temperature are the main effects at which the climate and atmosphere depend on, In this paper We choose three different places in Iraq to study correlations between (H/Ho) and (1/Tmax...

Abstract The development of safe and effective radioprotective agents with minimal side effects, particularly for high‐dose exposure, remains a global priority. E0703, a novel steroidal compound structurally derived fr...

Avaliou-se a eficácia do protocolo radioterápico hipofracionado no tratamento de felinos portadores de carcinoma epidermóide facial. Um protocolo hipofracionado de radioterapia foi aplicado em cinco gatos portadores d...

Objective: To identify risk factors for post-radiation xerostomia and to evaluate the tolerance to doses administered to the parotid gland in patients with nasopharyngeal carcinoma (NPC). Methods: A total of 462 patients...

Abstract Nanofluids have emerged as promising heat transfer media due to their superior thermal performance associated to conventional fluids, yet their behavior under mutual impacts of radiation, heat source/sink, and m...

Waterlogging is a severe stress that constrains crop production. We studied ecophysiological traits related to waterlogging tolerance in wheat, barley oilseed rape and field pea. Outdoor experiments using canopies of whe...

Abstract Purpose Intraoperative radiotherapy (IORT) is designed to deliver a precise dose of ionizing radiation to a tumor or tumor bed after surgical resection. The IORT procedure can deliver targeted radiation to the t...

Livestock production systems of Argentina show an ongoing process of change in the composition of their forage base, with a gradual increase in the proportion of their area assigned to forage crop sequences (FCS) −in p...

Gold nanoparticles (AuNPs) have been investigated extensively in the past twenty years as a sensitizing agent in photon radiotherapy. Targeted delivery of AuNPs to specific sites in cells and tissues contributes to highl...

Background and purpose: The use of Magnetic Resonance imaging (MRI) for radiotherapy (RT) planning for locally advanced non-small cell lung cancer (LA NSCLC) could improve RT precision due to its superior soft tissue def...
