Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, Volume 101, Issue 4, Page 1627-1640, August 2026.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Colour vision in marsupials

Colour vision in marsupials. The ability to distinguish colours is a crucial aspect of vision, providing vital data for sexual selection, predator detection and food acquisition. Studies of mammalian colour vision have largely overlooked marsupials.

Prognostic Factors for Postoperative Complications. An Aggregate Protocol for 10 Observational Studies From the Danish TRIPLE‐A Cohort of 1.2 Million Surgeries

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 7, August 2026.
ABSTRACT Background Postoperative complications substantially increase morbidity, mortality and healthcare costs. Understanding prognostic factors is essential for risk stratification, targeted prevention strategies, and development of prediction models.

Surgical Management of a Large Dentigerous Cyst Associated With an Impacted Supernumerary Tooth: A Rare Case Report

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Dentigerous cysts are the second most common odontogenic cysts, typically forming around the crowns of impacted teeth. Their association with supernumerary teeth is rare. This report presents the successful surgical management of an unusually large dentigerous cyst linked to an impacted supernumerary tooth in the right maxilla.

Marsupials: Alternative mammals

, 1981
Marsupials have come to be regarded as second class mammals, partly because of their unusual mode of reproduction, and partly because they were discovered long after the eutherians (or 'placental' mammals) and were all lumped into group, the Order ...

Karyotype characterization and nucleolar organizer regions of marsupial species (Didelphidae) from areas of Cerrado and Atlantic Forest in Brazil

Genetics and Molecular Biology, 2008
The karyotypes of 23 specimens belonging to 16 species from nine genera of Brazilian marsupials (family Didelphidae) were studied. The animals were collected in eight localities of Cerrado or Atlantic Forest biomes in the states of Goiás, Tocantins ...

Early Myelination Supports the Establishment of Consistent Handedness

Glia, Volume 74, Issue 7, July 2026.
Early compact myelin is essential for the establishment but not the maintenance of consistent paw preference in mice. Congenital myelin absence reduces lateralization and creates a leftward bias, underscoring a developmental role in shaping brain asymmetries. ABSTRACT Lateralization of brain functions, such as handedness, is thought to enhance cortical

Functional morphology of marsupial moles (Marsupialia: Notoryctidae)

, 2006
Marsupial moles (genus Notoryctes) are the most highly specialised burrowing marsupials. The specialisations of the appendicular musculo-skeletal system of the marsupial moles are extensive and widespread; the major alterations are concentrated in, but ...
