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 ...

Comparative Morphology and Mechanics of Aquatic and Terrestrial Feeding Salamanders

open access: yesJournal of Morphology, Volume 287, Issue 9, September 2026.
Jaw muscle size, bite force, and skull strength are driven by multiple factors, not just the difference between the two habitats. Necturus produces higher bite forces than Salamandra, but the stress distribution is less even in Necturus, suggesting Salamandra's skull shape is better adapated to resist feeding loads.

Reproducibility of Splanchnic Blood Flow Measured Using Phase‐Contrast MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 8, August 2026.
Splanchnic vessel blood flow assessment can describe physiology or pathophysiological conditions. Here, we assessed the variation of PC‐MRI‐determined repeated measures of blood flow in four splanchnic vessels in three populations and two MRI‐scanners. We found similar agreements with the means for both scanners and for healthy individuals and patients

Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 211-219, August 2026.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

open access: yesJournal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Artérias da base do encéfalo em suínos da linhagem Camborough 22

open access: yesBioscience Journal, 2006
As artérias da base do encéfalo foram estudadas em 40 suínos da linhagem Camborough 22, natimortos, de ambos os sexos. Destes, dez espécimes tiveram as artérias da cabeça preenchidas com solução corada de Acetato de vinyl, e por conseguinte submetidos ao
