Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

The Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...

Visual-Cerebellar Pathways and Their Roles in the Control of Avian Flight

Frontiers in Neuroscience, 2018
In this paper, we review the connections and physiology of visual pathways to the cerebellum in birds and consider their role in flight. We emphasize that there are two visual pathways to the cerebellum.

Mapping of the receptive fields in the optic tectum of chicken (Gallus gallus) using sparse noise. [PDF]

PLoS ONE, 2013
The optic tectum plays a key role in visual processing in birds. While the input from the retina is topographic in the superficial layers, the deep layers project to the thalamic nucleus rotundus in a functional topographical manner.

Human cerebral arterial morphogenesis explored by 3D microscopic imaging of cleared embryos: Bridging the gap between embryonic and adult anatomy

Journal of Anatomy, EarlyView.
We provide a description of human embryonic cerebral arterial development based on whole‐mount immunostaining, tissue clearing, three‐dimensional (3D) light‐sheet microscopy imaging, and anatomically informed virtual segmentation of human embryos. Findings are compared with adult radiological anatomy. We provide a detailed account of the development of

The OsWRKY15‐OsSUT3 Regulatory Module Enhances Rice Pollen Fertility by Mediating Sucrose Allocation to Anthers

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

Matrix metalloproteinase 14 in the zebrafish: an eye on retinal and retinotectal development. [PDF]

PLoS ONE, 2013
Matrix metalloproteinases (MMPs) are members of the metzincin superfamily of proteinases that cleave structural elements of the extracellular matrix and many molecules involved in signal transduction.

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, Volume 309, Issue 10, Page 2897-2912, October 2026.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Chick PTPσ regulates the targeting of retinal axons within the optic tectum [PDF]

, 2002
Chick PTP (cPTP), also known as CRYP, is a receptor-like protein tyrosine phosphatase found on axons and growth cones. Putative ligands for cPTP are distributed within basement membranes and on glial end feet of the retina, optic nerve, and optic tectum,
