Exploration of GES-induced masculinization of Gambusia affinis Based on Single Cell Level

open access: yesGuangdong nongye kexue, 2023
【Objective】To investigate the molecular mechanism of sex reversal in female Western mosquitofish (Gambusia affinis) under the effect of gestodene (GES) by studying the development of gonadal cell differentiation and gene expression changes involved in ...

Marine‐Derived Type I Collagen From Scyliorhinus canicula: Extraction, Characterization, and Biomedical Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
Marine‐derived type I collagen is extracted from Scyliorhinus canicula skin and characterized by physicochemical and morphological analyses. The collagen exhibits excellent biocompatibility, promotes wound healing, reduces inflammatory mediators, and inhibits melanogenesis.

The mechanosensory lateral line system mediates activation of socially-relevant brain regions during territorial interactions

open access: yesFrontiers in Behavioral Neuroscience, 2016
Animals use multiple senses during social interactions and must integrate this information in the brain to make context-dependent behavioral decisions. For fishes, the largest group of vertebrates, the mechanosensory lateral line system provides crucial ...

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Comparative Morphology and Generic Classification of Catfishes of the Trichomycterus Lineage (Siluriformes: Trichomycteridae)

open access: yesTaxonomy
Recent genomic phylogenies have generated new robust classifications of actinopterygian fishes, making possible greater nomenclatural stability, but genus-level classifications of groups like the diverse catfish subfamily Trichomycterinae are still ...

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

The Zebrafish Amygdaloid Complex – Functional Ground Plan, Molecular Delineation, and Everted Topology

open access: yesFrontiers in Neuroscience, 2020
In mammals and other tetrapods, a multinuclear forebrain structure, called the amygdala, forms the neuroregulatory core essential for emotion, cognition, and social behavior.

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

TRIM proteins and CXS chemokines : evolutionary dynamics and functional characterization of two large protein families in teleost fish [PDF]

open access: yes, 2012
Two large protein families with roles in the immune system were the subject of this thesis. In part one of the thesis, TRIM proteins were studied, which are part of an ancient intracellular immune system. In mammals, TRIM proteins were recently found to

Early evolution of the gular musculature and its innervation in ray‐finned fishes

open access: yesThe Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating
