Potential genotoxic risk related to simultaneous exposure to radionuclides and cytostatics

The aim of the study was to evaluate the genotoxic risk to medical personnel concurrently exposed to ionizing radiation and antineoplastics, using changes in their lymphocyte cell genome as a bioindicator. The study comprised 12 female nurses employed in the nuclear medicine hospital department and an equal number of matched controls. For each examinee, both conventional structural chromosomal aberration analysis and sister chromatid exchange test (SCE) were carried out. According to Student's t-test, neither the incidence of structural chromosomal aberrations (p > 0.6) nor the mean SCE-frequency rate (p > 0.3) were significantly increased among the exposed subjects. Nevertheless, in those exposed, irreparable chromosomal damages and wide SCE-ranges were observed. Such findings suggest the possibility of genotoxic implications of concurrent occupational exposure to ionizing radiation and antineoplastic drugs.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Signaling in Adult Neurogenesis

Neural stem cells play a critical role in the production of neuronal cells in neurogenesis is of great importance. Of interest is the role signalling mechanisms in adult neurogenesis. Discover the latest research on signalling in adult neurogenesis.

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
