Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]

, 2012
Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.

The Impacts of Pregnancy on Cognition and Cell Proliferation in a Live‐Bearing Fish (Poeciliopsis gracilis)

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
We assessed the impact of pregnancy on cognition and cell proliferation in the live‐bearing fish Poeciliopsis gracilis. Pregnant females showed reduced spatial learning but unchanged reversal learning, alongside decreased cell proliferation in the olfactory bulb and ventral telencephalon, indicating pregnancy‐induced cognitive and neural changes in a ...

Histone Density and Dynamics Shape Mitotic Chromatid Architecture in Xenopus Egg Extracts

Genes to Cells, Volume 31, Issue 3, May 2026.
Histone chaperones and chromatin remodelers modulate histone density and dynamics. The resulting local chromatin properties are integrated with DNA reconfiguration activities mediated by condensins and topoisomerase IIα to shape the global architecture of mitotic chromosomes.

When Pathways Converge: Iron, Lipid Peroxidation, and α‐Synuclein in Ferroptosis‐Driven Dopaminergic Neurodegeneration

Journal of Neurochemistry, Volume 170, Issue 4, April 2026.
Dopaminergic neurons are particularly susceptible to ferroptosis. Pacemaking activity–driven calcium (Ca2+) influx increases metabolic demand and reactive oxygen species (ROS) production, promoting iron release from aconitase. Alpha‐synuclein (α‐syn) enhances iron uptake via transferrin receptor 1 (TfR1) and exhibits ferrireductase activity, converting

Organ‐Specific Histopathological Effects of Prenatal Alcohol Exposure: A Narrative Review

Congenital Anomalies, Volume 66, Issue 1, January/February 2026.
ABSTRACT The role of alcohol‐induced epigenetic modifications that predispose the fetus to metabolic dysregulation, increased susceptibility to future substance use, and long‐term behavioral and cognitive impairments has received increasing attention.

Chelation Therapy for Rare Earth Element Toxicity: Current Evidence, Challenges and Future Directions

Basic &Clinical Pharmacology &Toxicology, Volume 138, Issue 1, January 2026.
ABSTRACT The accelerating integration of rare earth elements (REEs) in advanced technologies has generated rising concern over human exposure and the attendant toxicological risks. This review presents an up‐to‐date synthesis of current evidence on REE toxicity across multiple exposure pathways, including inhalation, ingestion and occupational contact,

Dynamics of Sea Urchin Gastrulation Revealed by Tracking Cells of Diverse Lineage and Regulatory State [PDF]

, 2011
During gastrulation in the sea urchin embryo the archenteron, or primitive gut, is formed by an initial process of invagination at the vegetal pole of the embryo, followed by extension across the blastocoel toward the future mouth.

Developmental Patterns of Hepatic Peroxisome Proliferator‐Activated Receptor (PPAR) Expression in Xenopus laevis and Response to Pharmaceutical Agonists During Metamorphic Climax

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 10, Page 1191-1204, December 2025.
ABSTRACT Peroxisome proliferator‐activated receptors (PPAR) are master transcriptional regulators that maintain metabolic homeostasis in vertebrates. Amphibians are often exposed to endocrine disrupting compounds (EDCs) that could dysregulate lipid metabolism.

Coordination of Hox identity between germ layers along the anterior-to-posterior axis of the vertebrate embryo [PDF]

, 2010
During early embryonic development, a relatively undifferentiated mass of cells is shaped into a complex and morphologically differentiated embryo. This is achieved by a series of coordinated cell movements that end up in the formation of the three ...
