Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Virus‐specific alterations in placental structure and transporter expression following maternal arbovirus infection

The Journal of Physiology, EarlyView.
Abstract figure legend Arboviruses induce virus‐specific alterations in placental structure and functional markers. Chikungunya virus (CHIKV) exposure was associated with reduced syncytiotrophoblast and syncytial knot areas, increased cytotrophoblast proliferation (Ki‐67) and thyroid transporter (MCT8) expression, reduced protective (P‐gp and BCRP ...

Little devils of Neotropical forests: A first molecular phylogeny of stygnid harvestmen with UCE‐museomics and a gigamatrix approach (Arachnida, Opiliones, Stygnidae)

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First family‐wide phylogenomic framework of Stygnidae using UCE‐museomics and a gigamatrix approach establishes a novel three‐subfamily classification, erecting the new subfamily Auraninae subfam. nov. Signatures of severe incomplete lineage sorting and short deep internodes suggest a rapid early‐burst Neotropical radiation, driving phylogenetic ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 385-400, March 2026.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.
