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 ...
