Dorsoventral splitting of the infundibulum in a child with pituitary hypoplasia
Radiology Case Reports, 2023 Pituitary development arises from ectodermal tissue creating Rathke's pouch and ultimately the adenohypophysis anteriorly whereas neuroectodermal tissue arising from the diencephalon creates the neurohypophysis posteriorly. Alterations in pituitary development can lead to hormonal dysregulation and dysfunction. Following clinical suspicion of pituitary

Larval trematodes infecting the South-American intertidal mud snail Heleobia australis (Rissooidea: Cochliopidae) [PDF]
, 2014 Larval trematodes infecting the snail Heleobia australis (Cochliopidae) from the Bahía Blanca estuary, Argentina were surveyed for two years. A total of 7,504 snail specimens was dissected and the larval stages of 15 different trematodes were recovered ...

Evolution of Development: Diversified Dorsoventral Patterning [PDF]
Current Biology, 2011 Patterning of the dorsoventral axis by graded BMP signaling is conserved in the evolution of animals. However, this system has also proven to be highly adaptable, as is now highlighted by its short-range function in the leech Helobdella.

Synthetic epoxy-pregnan steroids: effects on anxiety behavior in rats [PDF]
, 2016 Neurosteroids like 3α-OH-5α-pregnan-20-one (allopregnanolone) and 3α-OH-5β-pregnan-20-one (pregnanolone) modulate the γ-aminobutyric acid-A (GABAA) receptor function and produce several effects that can be considered for therapeutical pruposes like ...

Radial or bilateral? The molecular basis of floral symmetry. [PDF]
, 2020 In the plant kingdom, the flower is one of the most relevant evolutionary novelties. Floral symmetry has evolved multiple times from the ancestral condition of radial to bilateral symmetry.

Extraocular motoneuron pools develop along a dorsoventral axis in zebrafish, Danio rerio
The Journal of comparative neurology, 2016 Both spatial and temporal cues determine the fate of immature neurons. A major challenge at the interface of developmental and systems neuroscience is to relate this spatiotemporal trajectory of maturation to circuit‐level functional organization.

BMP suppresses WNT to integrate patterning of orthogonal body axes in adult planarians.
PLoS Genetics, 2023 Adult regeneration restores patterning of orthogonal body axes after damage in a post-embryonic context. Planarians regenerate using distinct body-wide signals primarily regulating each axis dimension: anteroposterior Wnts, dorsoventral BMP, and ...

Prickle1 is required for EMT and migration of zebrafish cranial neural crest [PDF]
, 2019 The neural crest—a key innovation of the vertebrates—gives rise to diverse cell types including melanocytes, neurons and glia of the peripheral nervous system, and chondrocytes of the jaw and skull.

The origin of dorsoventral polarity inDrosophila [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003 InDrosophiladorsoventral (DV) polarity arises during oogenesis when the oocyte nucleus moves from a central posterior to an asymmetrical anterior position. Nuclear movement is a symmetry–breaking step and establishes orthogonality between the anteroposterior and the DV axes.
