The Hemodynamic Trap: Fetal‐Type Posterior Cerebral Artery and Occult PICA Aneurysms

open access: yesClinical Case Reports, Volume 14, Issue 10, October 2026.
Hemodynamic and structural asymmetry of the vertebrobasilar system. (A) Axial Maximum Intensity Projection (MIP) demonstrating a right‐sided fetal‐type posterior cerebral artery (fPCA). The right PCA arises directly from the internal carotid artery (red circle), with an absent P1 segment. (B) Coronal MIP reveals striking inflow asymmetry, characterized

Conserved and Tissue‐Specific RNA and Protein Cargos of Small Extracellular Vesicles From 120 Tissue Sites Across 34 Organs in a Single Pig

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 10, October 2026.
A whole‐body map of sEVs from a single pig, including 133 samples spanning 10 systems, revealed striking tissue‐specific heterogeneity in yield. Importantly, a conserved core cargo set comprising candidate sEV markers (ACTG1, CFL1, and ANXA2), RNA‐binding proteins, the let‐7 miRNA family, and ferritin genes was defined from 105,409 (88.6% full‐length ...

Quantifying Cardiac, Respiratory, and Low Frequency Components of CSF Motion From fMRI Inflow Effects

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1916-1928, October 2026.
ABSTRACT Purpose Cerebrospinal fluid (CSF) flow oscillations have emerged as a potentially important marker related to brain clearance, but their acquisition often relies on specialized imaging MRI sequences. The purpose of this work was to enable quantitative assessment of CSF flow associated with cardiac, respiratory, and low‐frequency cycles using ...

Cranio-cervical conundrum; Enigmatic complete atlanto-occipital assimilation with Chairi I malformation

open access: yesRadiology Case Reports
Atlanto-occipital assimilation is extremely rare congenital anomaly, characterized by partial or complete fusion of atlas and occipital bone leading to altered cranio-cervical junction anatomy.

Prenatal findings and postnatal outcomes in cases of closed spinal dysraphism: 10‐year two‐center cohort study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 4, Page 518-526, October 2026.
ABSTRACT ObjectiveTo characterize prenatal ultrasound findings in fetuses with prenatally diagnosed closed spinal dysraphism (CSD) and report their postnatal management and functional outcomes at 18 and 36 months. MethodsThis retrospective cohort study included all fetuses with a prenatal diagnosis of CSD assessed between January 2014 and December 2024

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 787-802, October 2026.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Association of the Achondroplasia Foramen Magnum Score and intraoperative neuromonitoring. [PDF]

open access: yes
INTRODUCTION: Foramen magnum stenosis in achondroplasia carries a risk of sudden death. A proportion of these patients benefit from foramen magnum decompression (FMD). The Achondroplasia Foramen Magnum Score (AFMS) was developed to stratify those most at

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 821-846, October 2026.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

Invisible gems: Phylogenomics of Tetrastichinae jewel wasps (Hymenoptera: Eulophidae) reveals cryptic taxa and rampant polyphyly Osynliga juveler: fylogenomiska analyser av glanssteklar i underfamiljen Tetrastichinae (Hymenoptera: Eulophidae) avslöjar polyfyli och kryptiska taxa

open access: yesSystematic Entomology, Volume 51, Issue 4, October‐December 2026.
Most extensive phylogenetic study of Tetrastichinae to date including a third of all currently described genera, based on 3033 BUSCOs, 1820 UCEs and 12 mitochondrial protein‐coding genes. A major taxonomic revision of the group is needed, as many tetrastichine genera are either poly‐ or paraphyletic.
