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...

The huge rise in the number of medical images has caused a major problem in radiology departments. Radiologists are now working harder than ever, which affects the quality of their diagnoses and patient care. It takes 15...

Abstract Objective To systematically evaluate the efficacy differences between stereotactic radiosurgery (SRS) and whole-brain radiotherapy (WBRT) in treating brain metastases from small cell lung cancer (SCLC), and to a...

Abstract Animal-origin food products pose serious threat to public food safety due to high microbial loads. The microbial and radioactive contaminations in commercial cold duck meat products were evaluated. Ten different...

ABSTRACT Purpose: The combination of radiotherapy and immunotherapy (radioimmunotherapy) shows promising antitumor efficacy but raises cardiotoxicity concerns. The underlying mechanisms remain unclear. Methods: Preclinic...

Abstract The effect of Cu(II) ions on the decomposition of organic peroxides produced in the γ-radiolysis of threonine aqueous oxygenated solutions have been studied under various experimental conditions including diffe...

Objective: To assess the efficacy and safety of Qixuekang oral liquid in the treatment of leukopenia during chemotherapy and radiotherapy. Methods: This randomized, double-blind, placebo-controlled, multicenter clinical ...

Background: Thyroid cancer is one of the most prevalent endocrine neoplasms in Brazil, and radioiodine therapy (RAI) is a well-established adjuvant treatment. However, managing RAI can be particularly challenging in pati...

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...

Studying demographic changes in past human populations is of great interest due to their role in processes of cultural change as well as the biological evolution of populations. Despite this, a general consensus about th...

Background: During the peak of the coronavirus disease 2019 (COVID-19) pandemic, radiographers in Zambia faced heavy workloads as chest X-ray referrals outpaced staffing and the capacity of X-ray imaging equipment, and ...

Abstract Background This systematic review and meta-analysis evaluates the safety and efficacy of emerging prostate-specific membrane antigen (PSMA) radioligand therapy (RLT) agents used beyond [¹⁷⁷Lu]Lu-PSMA in met...

We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on the European Southern Observatory Very Large Telescope. MAGPI is designed to study the physi...

Background: Photogrammetry is a safe and non-invasive technique for evaluating posture in clinical settings. Body Vision is a novel system that employs photogrammetric principles to assess postural parameters. This study...

Global Navigation Satellite System Radio Occultation (GNSS-RO) offers a unique means of retrieving vertical atmospheric profiles with high precision and global coverage. This study investigates the spatiotemporal charact...

BackgroundDelivering accurate radiation doses in heterogeneous tissues is critical in radiotherapy, yet conventional algorithms often lose accuracy in complex scenarios. Monte Carlo (MC) simulation offers a high-fidelity...

IntroductionTo optimize radiotherapy treatment and minimize toxicities, effective segmentation of organs-at-risk (OARs) and clinical target volume (CTV) is essential. Deep learning (DL) models can achieve high segmentati...

ABSTRACT We studied the home range and habitat use of paca (Cuniculus paca) in a rural agricultural community in the Alto Beni region, in La Paz department, Bolivia, where game meat is the main source of protein for a la...

a-amylase enzyme was isolated and purified from wheat flour (abena zero). Different aqueous enzyme solutions were exposed to gamma radiation in order to investigate the behavior of this enzyme toward ionization radiation...

Context. Pulsars have an overall very stable rotation. However, sudden increases in their rotation frequency, known as glitches, perturbtheir evolution. While many observatories commonly detect large glitches, small glit...

Context. Hot cores are signposts of the protostellar activity of dense cores in star-forming regions. W43-MM1 is a young region that is very rich in terms of high-mass star formation, which is highlighted by the presence...

In this paper, the assessment of the radon exhalation rate of the Modica stone building material, untreated and accelerated aged through salt crystallization test, is reported as a case study. Noteworthy, this constructi...

My paper analyzes the beginning of the Roma emancipation movement in communist Romania by focusing on the activity of the Roma sociologist and activist, Nicolae Gheorghe. It is divided in three parts. The first part desc...

ABSTRACT Background and Aim As dental anomalies can significantly affect esthetic and function, early detection and diagnosis are crucial for treatment and minimizing potential negative effects. Artificial intelligence (...
