Abstract

The range and distribution of Sister-Chromatid Exchange (SCE) scores in 479 control persons were determined. All SCE readings were performed in a single laboratory according to the same protocol and regularly checked by referee readers to assure consistency. A mean SCE per cell value of 9.9 and a 95th percentile of 13.4 were established for this study sample. The range of SCE scores across all non-exposed individuals tested was 5.0-17.5 SCE per cell. Differences in SCE scores were associated with reader, smoking, sex, and, to a small extent, age. Individual test results showed reasonable consistency across the entire control group, but, as with most clinical measurements, care should be taken to avoid placing too much emphasis on a single test result when communicating with an individual. This report on the largest control group studied to date provides necessary normative data for further SCE investigations in occupational settings.

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.
