Cellular aging associated with telomeric shortening plays an important role in female fertility. In addition to natural decline, due to the loss of telomeric repeats during cell division, other factors such oxidative stress (OS), accelerate telomere shortening by causing a dramatic loss of telomeric repeats. Thus, mathematical models to better understand the accelerated aging leading to infertility are lacking in the literature.

Plasmids are fundamental to molecular biology and biotechnology, playing a crucial role in bacterial evolution. Some plasmids are linked to complex cellular dynamics, including pathogenicity islands, antibiotic resistance, and gene mobilization. This study reports the isolation and sequencing of two cryptic plasmids with different electrophoretic mobilities from the Escherichia coli clinical isolate O55.

Objective: The serotonin system has long been implicated in autism spectrum disorder. A previous study reported lower whole blood serotonin (WB5-HT) concentrations in the mothers of children with more severe autism. This study attempted to replicate this finding in an independent cohort.

Protein-nucleic acid binding sites play a crucial role in biological processes such as gene expression, signal transduction, replication, and transcription. In recent years, with the development of artificial intelligence, protein language models, graph neural networks, and transformer architectures have been adopted to develop both structure-based and sequence-based predictive models. Structure-based methods benefit from the spatial relationship between residues and have shown promising performance.

Applying our model, JODIE, to 30,000 child-mother-father trios with phased DNA information from the Estonian Biobank (EstBB) and the Norwegian Mother, Father, Child Cohort (MoBa), we jointly estimate the phenotypic variance attributable to these four effects unbiased of assortative mating (AM) for height, body mass index (BMI) and childhood educational test score (EA). For all three traits, direct effects make the largest contribution to the genetic effect variance.
