A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Human Amniotic Fluid Mesenchymal Stem Cells from Second- and Third-Trimester Amniocentesis: Differentiation Potential, Molecular Signature, and Proteome Analysis

open access: yesStem Cells International, 2015
Human amniotic fluid stem cells have become an attractive stem cell source for potential applications in regenerative medicine and tissue engineering. The aim of this study was to characterize amniotic fluid-derived mesenchymal stem cells (AF-MSCs) from ...

Trabecular bone ontogeny of the human talus

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Correlation of Neopterin Concentrations In Amniotic Fluid and Urine of Pregnant Women at Delivery

open access: yesPteridines, 1999
Median neopterin concentration in amniotic fluid at delivery was 72 nM which is approximately 10-fold the maternal and fetal serum concentration. A strong correlation existed between neopterin concentrations in amniotic fluid and urine, except an ...

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Perfluorooctane Sulfonate Concentrations in Amniotic Fluid, Biomarkers of Fetal Leydig Cell Function, and Cryptorchidism and Hypospadias in Danish Boys (1980–1996)

open access: yesEnvironmental Health Perspectives, 2015
Background Exposure to perfluorooctane sulfonate (PFOS) may potentially disturb fetal Leydig cell hormone production and male genital development. Objectives We aimed to study the associations between levels of amniotic fluid PFOS, fetal steroid hormone,

Characterization of the extracellular matrix from human and dog umbilical cords

open access: yesThe Anatomical Record, EarlyView.
Abstract The extracellular matrix is important for maintaining tissue morphogenesis and homeostasis; it can also be used as a biomaterial for the production of biological scaffolds. Particularly, the umbilical cord has shown potential in the production of scaffolds for small‐diameter vessels.

The effects of enteral artificial amniotic fluid-containing erythropoietin on short term outcomes of preterm infants

open access: yesThe Turkish Journal of Pediatrics, 2019
Necrotizing Enterocolitis (NEC) is a common devastating gastrointestinal disease, which usually develops in premature infants. Erythropoietin (EPO) as a hematopoietic hormone produced by the kidney can also be naturally found in amniotic fluid and ...
