Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

open access: yesThe Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Effects of Medial Preoptic Lesions on\ud Placentophagia and on the Onset of Maternal\ud Behavior in the Rat [PDF]

open access: yes, 1979
Lesions of the medial preoptic area (MPO) were produced through permanently indwelling electrodes 24 hr prior to parturition in pregnant rats, or 24 hr prior to donor-placenta presentation in virgin rats determined in a pretest to be placentophages.

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

open access: yesThe Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

open access: yesHepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Placenta Accreta

open access: yesمجلة كلية الطب, 2007
Placenta accrete is defined as an abnormally adherent placenta that is directly attached to the myometrium because of inadequate development of the fibrinoid layer (Nitabuch layer) and absence of decidua basilis either partially or totally.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

open access: yes, 2019
The current recommendation for umbilical cord management of non-vigorous infants (limp, pale, and not breathing) who need resuscitation at birth is to immediately clamp the umbilical cord.
