Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Identification of a De Novo MAGEL2 Pathogenic Variant in Schaaf–Yang Syndrome and the Importance of Paternal Allele Confirmation

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This study reports a de novo MAGEL2 pathogenic variant in a patient with Schaaf–Yang syndrome, confirmed through methylation‐sensitive analysis. Combining genomic sequencing with methylation assays helps accurately determine the parental origin of MAGEL2 mutations.

The usefulness of chromosomes of parasitic wasps of the subfamily Eupelminae (Hymenoptera: Chalcidoidea: Eupelmidae) for subfamily systematics

open access: yesEuropean Journal of Entomology, 2008
Karyotypes of 16 Eupelminae species were analyzed. The haploid chromosome number was found to be much more diverse than the n = 5 previously recorded for three studied species.
