Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

The Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Anterior-to-Posterior Migration of a Lumbar Disc Sequestration. Surgical Remarks and Technical Notes about a Tailored Microsurgical Discectomy [PDF]

, 2017
Extrusion of disc material within the spinal canal complicates up to 28.6% of lumbar disc herniations. Due to the anatomical "corridors" created by the anterior midline septum and lateral membranes, relocation occurs with an anterior and anterolateral ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Sacrococcygeal teratoma with spinal canal invasion

Journal of Pediatric Surgery Case Reports, 2018
We report a case of a neonate with Altman typeⅠsacrococcygeal teratoma (SCT) with spinal canal involvement, in which ultrasonography was useful in the evaluation of the tumor progression into the spinal canal.

Lesion-induced generation of interneuron cell types in specific dorsoventral domains in the spinal cord of adult zebrafish [PDF]

, 2012
In contrast to mammals, adult zebrafish regenerate neurons in the lesioned spinal cord. For example, motor neurons are generated from an olig2-expressing population of pMN-like ependymoradial glial cells in a ventrolateral position at the central canal ...

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

The Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.
