Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice

Advanced Science, EarlyView.
This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.

Endometrial Epithelial Lactate Deficiency Drives CD8+ T‐Cells Dysregulation in Unexplained Recurrent Implantation Failure

Advanced Science, EarlyView.
Unexplained recurrent implantation failure (RIF) represents a significant clinical challenge. Our results demonstrate that reduced lactate production in the RIF endometrium impairs the suppression of cytotoxic CD8+ T‑cells, allowing their proliferation and thereby disrupting the local immune balance essential for successful embryo implantation.

Maternal and neonatal outcomes during COVID-19 pandemic and pre-pandemic in an urban slum in North India – A community-based ambispective cohort study

Journal of Family Medicine and Primary Care
Background: Coronavirus disease 2019 (COVID-19) has affected millions of people globally since its first case reported on December 2019 in Wuhan, China. The maternal and neonatal outcomes during COVID-19 pandemic were not much reported in low- and middle-

From Cell‐Free Transcriptomes to Single‐Cell Landscapes: Biomarker Discovery and Originating Cell Alteration Analysis via Graph Matrix Factorization

Advanced Science, EarlyView.
CellFreeGMF traces plasma cfRNA to likely originating cell types by integrating single‐cell atlases with graph‐regularized matrix factorization. The method decomposes cfRNA profiles into sample–cell contributions to reconstruct pseudo single‐cell expression.

Trained Memory of Uterine Macrophages Improves Subsequent Pregnancy Outcomes

Advanced Science, EarlyView.
This study identifies that pregnancy imprints a durable, pregnancy‐specific form of trained immune memory in uterine macrophages, marked by the emergence of LILRB3+/PIR‐B+ cells that expand across gestations, acquire a tolerogenic and metabolically rewired phenotype, and actively protect against inflammatory pregnancy loss in mice.

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

Advanced Science, EarlyView.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Nanoplastics and Neurodegeneration: A Roadmap From Mechanism to Causation

Advanced Science, EarlyView.
Nanoplastics are pervasive environmental contaminants with potentially profound implications for human health. Emerging evidence suggests a possible link between nanoplastic exposure and neurodegeneration, a key driver of ageing and dementia, yet causality remains unresolved.
