A comparative genomic analysis at the chromosomal-level reveals evolutionary patterns of aphid chromosomes [PDF]

Communications Biology
Genomic rearrangements are primary drivers of evolution, promoting biodiversity. Aphids, an agricultural pest with high species diversity, exhibit rapid chromosomal evolution and diverse karyotypes.

Assessment of Foetal Nuchal Translucency and its Relationship with Crown Rump Length in Normal Foetuses using Ultrasonography in a Subset of South Indian Population [PDF]

Journal of Clinical and Diagnostic Research, 2022
Introduction: Assessing Nuchal Translucency (NT) accurately is necessary in detection of various anomalies as described in the literature. Studies deriving reference range for NT in Indian population is not widely available.

Quantification of Female Chimeric Cells in the Tonsils of Male Children and Their Determinants

Cells, 2023
The factors influencing mother-to-child cell trafficking and persistence over children’s lives have yet to be established. The quantification of maternal microchimerism was previously reported through HLA-based approaches, which introduced bias regarding

Model selection emphasises the importance of non-chromosomal information in genetic studies. [PDF]

PLoS ONE, 2015
Ever since the case of the missing heritability was highlighted some years ago, scientists have been investigating various possible explanations for the issue. However, none of these explanations include non-chromosomal genetic information.

Multiple independent chromosomal fusions accompanied the radiation of the Antarctic teleost genus Trematomus (Notothenioidei:Nototheniidae)

BMC Evolutionary Biology, 2020
Background Chromosomal rearrangements are thought to be an important driving force underlying lineage diversification, but their link to speciation continues to be debated.
