PLoS ONE, 2011 Genomic imprinting is a form of gene dosage regulation in which a gene is expressed from only one of the alleles, in a manner dependent on the parent of origin.

The Origins of Genomic Imprinting in Mammals
, 2019 Genomic imprinting is a process that causes genes to be expressed according to their parental-origin. Imprinting appears to have evolved gradually in two of the three mammalian subclasses with no imprinted genes yet identified in prototheria and only ...

Mass Spectrometry Reviews, EarlyView.ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Genomic imprinting absent in Drosophila melanogaster adult females.
, 2018 Genomic imprinting occurs when expression of an allele differs based on the sex of the parent that transmitted the allele. In D. melanogaster, imprinting can occur, but its impact on allelic expression genome-wide is unclear.

Genetic Investigation in Fetal Growth Restriction: An Integrated Approach for Clinical Practice
Prenatal Diagnosis, EarlyView.ABSTRACT International guidelines recommend genetic testing when fetal growth restriction (FGR) accompanies structural anomalies, but recommendations for apparently isolated FGR remain variable, particularly regarding gestational age thresholds and the role of exome sequencing (ES). Interpretation is difficult because studies define FGR inconsistently,

Prenatal Diagnosis, EarlyView.ABSTRACT Objective To characterize the overall diagnostic yield of sequential chromosomal microarray (CMA) and exome sequencing (ES) across the phenotypic spectrum of fetal growth restriction (FGR). Methods A retrospective cohort of 320 consecutive FGR pregnancies presenting at ≥ 20 weeks to a tertiary fetal medicine unit (2020–2025).

Small Methods, EarlyView.This comprehensive review delivers an engineering‐centric analysis of microfluidic molecular diagnostic chips, breaking them down into foundational modules from fluid manipulation to bio‐sensing. Beyond chip design, it evaluates sample‐to‐answer integration strategies and commercial readiness levels.

Imprinting as Basis for Complex Evolutionary Novelties in Eutherians
BiologyThe epigenetic phenomenon of genomic imprinting is puzzling. While epigenetic modifications in general are widely known in most species, genomic imprinting in the animal kingdom is restricted to autosomes of therian mammals, mainly eutherians, and to a ...

Evidence of parental care as a newly identified reproductive isolating barrier
Journal of Animal Ecology, EarlyView.Behavioural variation can contribute to reproductive isolation and can be an important driver of speciation. Here, we show that a previously undescribed mechanism, parental care, can function as a postzygotic reproductive isolating barrier when dysregulated in hybrids.

Integrative Zoology, EarlyView.This study shows how ecological transitions, such as reforestation in Southeast Asia, reshape host–microbe–pathogen dynamics at the wildlife–domestic interface. By integrating long‐read microbiome sequencing, ecological gradients, and statistical and network analysis, we identify host species that disproportionately contribute to pathogen diversity and
