Abstract

The aim of the present study was to evaluate genome damage induced in peripheral blood lymphocytes of Croatian health care workers occupationally exposed to cytotoxic drugs. A comprehensive multi-biomarker approach using the alkaline comet assay and cytogenetic endpoints (analysis of structural chromosome aberrations, SCE assay, lymphocyte proliferation kinetics and cytokinesis-block micronucleus assay) was employed. The study included two populations of subjects: 50 health care workers occupationally exposed to cytotoxic drugs and 50 control subjects matched in age, gender and smoking habit. An investigation regarding the handling practice with cytotoxic drugs was conducted in parallel. Results obtained indicate high exposure levels at workplace that should be reduced. The values recorded among the occupationally exposed subjects were as follows: mean comet tail length: 17.46+/-0.08 microm; the incidence of long-tailed nuclei: 54.68+/-3.93%; 4.48+/-0.33 structural chromosome aberrations per 200 cells; 5.81+/-0.04 SCE per 50 cells; 29.28+/-2.21% of high-frequency cells; proliferation rate index: 1.97+/-0.12; and 16.32+/-0.85 micronuclei per 1000 binuclear cells. All these values indicated higher levels of DNA and cytogenetic da...Continue Reading

COVID-19

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

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.
