Double aneuploidy 48,ХХХ,+21 of a Bulgarian newborn with Down phenotype: a case report
Egyptian Journal of Medical Human Genetics, 2020 Background Aneuploidy is one of the most important chromosomal aberrations, which involves an abnormal number of the chromosomes. Trisomy 21 (Down syndrome) and numerical aberrations of the sex chromosomes have a relatively high prevalence in the general

The micronucleus assay as a biological dosimeter of in vivo ionising radiation exposure [PDF]
, 2010 Biological dosimetry, based on the analysis of micronuclei (MN) in the cytokinesis-block micronucleus (CBMN) assay can be used as an alternative method for scoring dicentric chromosomes in the field of radiation protection.

Genetic disorders and male infertility
Reproductive Medicine and Biology, 2020 Background At present, one out of six couples is infertile, and in 50% of cases, infertility is attributed to male infertility factors. Genetic abnormalities are found in 10%‐20% of patients showing severe spermatogenesis disorders, including non ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
