Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Maternal and infant gut microbiome

open access: yesiMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Influence of 17α-Methyltestosterone on Morphological Deformities and Pigmentation Development in Juvenile Japanese Eels, Anguilla japonica

open access: yesAnimals
17α-methyltestosterone (MT) is a synthetic steroid used to induce masculinization when administered during the larval stage of fish. However, the side effects of MT on eel are still poorly understood and, in this study, we examined the various effects of

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

Juvenile hormone regulates the maturation of sexually dimorphic naive ethanol olfactory preference in Drosophila melanogaster

open access: yesRoyal Society Open Science
The molecular mechanisms underlying the maturation of innate reward behaviours remain poorly understood. We have identified a sexually dimorphic innate reward behaviour in Drosophila melanogaster that varies depending on the age, sex and mating status in

Reduced Food Availability Amplifies Behavioral Depression and Impairs Locomotor Performance After Immune Challenge in Xenopus laevis

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Food restricition amplifies the reduction in voluntary locomotion after immune challenge in Xenopus laevis, ilustrating the energetic trade‐off between immunity and performance. ABSTRACT Mounting an immune response and locomotor activity are energetically costly processes that can generate trade‐offs affecting energy allocation, muscle performance, and

A case report of non‐syndromic colonic ganglioneuroma in a patient with juvenile polyposis

open access: yesJPGN Reports, EarlyView.
Abstract Colonic ganglioneuromas in children are rare, particularly without associated hereditary syndromes like multiple endocrine neoplasia (MEN2B), neurofibromatosis type 1(NF1), or Phosphatase and tensin homolog hamartoma tumor syndrome (PHTS). We report a 12‐year‐old male with a history of juvenile polyposis syndrome (JPS) and segmental colonic ...

Effectiveness of Juvenile Eriocheir sinensis in Controlling Pomacea canaliculata and Their Growth and Nutritional Response to Feeding on the Snail

open access: yesAnimals
In recent years, Pomacea canaliculata has aggressively invaded rice fields in Asia, resulting in significant agricultural losses. Biological control can effectively reduce the damage caused by P. canaliculata. This research evaluates E.
