Thoracic radiography of healthy captive male and female Squirrel monkey (Saimiri spp.). [PDF]

open access: yesPLoS ONE, 2018
The purpose of this prospective study was to describe the normal anatomy and provide reference ranges for measurements of thoracic radiography on Squirrel monkeys (n = 13).

Cell type boundaries organize plant development

open access: yeseLife, 2017
In plants the dorsoventral boundary of leaves defines an axis of symmetry through the centre of the organ separating the top (dorsal) and bottom (ventral) tissues.

The origin of dorsoventral polarity inDrosophila [PDF]

open access: yesPhilosophical 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.

Maternal and Zygotic Control of Zebrafish Dorsoventral Axial Patterning

open access: yes, 2011
Vertebrate development begins with precise molecular, cellular, and morphogenetic controls to establish the basic body plan of the embryo. In zebrafish, these tightly regulated processes begin during oogenesis and proceed through gastrulation to ...

Cannabinoid Modulation of Excitability and Short-Term Neuronal Dynamics in the Dorsal and Ventral Hippocampus

open access: yesBiology
Endocannabinoids, acting primarily through CB1 receptors, are critical modulators of neuronal activity, influencing cognitive functions and emotional processing.

Dorsoventral regulation of photosynthetic functions related to morphological and anatomical structures in field-grown sorghum

open access: yesPhotosynthetica, 2019
The rapid dorsoventral regulation of photosynthesis is important because the light conditions around both surfaces of field-grown leaves vary considerably.

β-adrenergic receptor-induced E-S potentiation in the dorsal and ventral hippocampus

open access: yesFrontiers in Synaptic Neuroscience
β-adrenergic receptors (β-ARs) play a critical role in modulating learning, memory, emotionality, and long-term synaptic plasticity. Recent studies indicate that β-ARs are necessary for long-term potentiation (LTP) induction in the ventral hippocampus ...

Shake a tail feather: the evolution of the theropod tail into a stiff aerodynamic surface.

open access: yesPLoS ONE, 2013
Theropod dinosaurs show striking morphological and functional tail variation; e.g., a long, robust, basal theropod tail used for counterbalance, or a short, modern avian tail used as an aerodynamic surface.

BMP suppresses WNT to integrate patterning of orthogonal body axes in adult planarians.

open access: yesPLoS 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 ...

Implications for dorsoventral axis determination from the zebrafish mutation janus

open access: yes, 1994
THE mechanisms underlying the formation of dorsoventral polarity in the zebrafish Danio rerio are unknown. Here we describe the zebrafish recessive maternal-effect mutation janusm55.
