The exfoliation of irradiated nuclear graphite by treatment with organic solvent: A proposal for its recycling [PDF]

open access: yes, 2019
For the past 50 years, graphite has been widely used as a moderator, reflector and fuel matrix in different kinds of gas-cooled reactors. Resulting in approximately 250,000 metric tons of irradiated graphite waste.

Embryonic Exposure to the Benzotriazole Ultraviolet Stabilizer 2‐(2H‐benzotriazol‐2‐yl)‐4‐methylphenol Decreases Fertility of Adult Zebrafish (Danio rerio)

open access: yesEnvironmental Toxicology and Chemistry, Volume 43, Issue 2, Page 385-397, February 2024.
Abstract Benzotriazole ultraviolet stabilizers (BUVSs) are emerging contaminants of concern. They are added to a variety of products, including building materials, personal care products, paints, and plastics, to prevent degradation caused by ultraviolet (UV) light.

IGFs mediate the action of LH on oocyte maturation in zebrafish.

open access: yesMolecular Endocrinology, 2015
LH signaling is required for oocyte maturation in fish and other vertebrates. However, the downstream factors mediating LH signaling are largely unexplored in fish.

Early Depletion of Primordial Germ Cells in Zebrafish Promotes Testis Formation [PDF]

open access: yes, 2015
As complete absence of germ cells leads to sterile males in zebrafish, we explored the relationship between primordial germ cell (PGC) number and sexual development.

The P450 side chain cleavage enzyme Cyp11a2 facilitates steroidogenesis in zebrafish [PDF]

open access: yes, 2020
Cytochrome P450 side-chain cleavage enzyme, encoded by the CYP11A1 gene, catalyzes the first and rate-limiting step of steroid hormone biosynthesis. Previous morpholino knockdown studies in zebrafish suggested cyp11a2 is a functional equivalent of human ...

Emotion Regulation Ability and Resilience in a Sample of Adolescents from a Suburban Area [PDF]

open access: yes, 2017
Earlier research has identified a remarkable number of related factors to resilience during adolescence. Historically, theoretical treatments of resilience have been focused almost exclusively on psychosocial levels of analysis to derive explanatory ...

11β-hydroxylase loss disrupts steroidogenesis and reproductive function in zebrafish [PDF]

open access: yes, 2020
The roles of androgens in male reproductive development and function in zebrafish are poorly understood. To investigate this topic we employed CRISPR/Cas9 to generate cyp11c1 (11β-hydroxylase) mutant zebrafish lines. Our study confirms recently published

Influence of temperature and feeding on early sexual maturation commitment in male Atlantic salmon (Salmo salar, L.) during the freshwater stage [PDF]

open access: yes, 2021
The intensification of Atlantic salmon (Salmo salar) post-smolt production to enhance growth performance has promoted a rise in precocious male maturation rates. Unlike traditional parr maturation, which seems to be highly dependent on genetic background,

Fsh stimulates Leydig cell Wnt5a production, enriching zebrafish type A spermatogonia.

open access: yesJournal of Endocrinology, 2018
Follicle-stimulating hormone (Fsh) modulates vertebrate spermatogenesis by regulating somatic cell functions in the testis. We have found previously that zebrafish Fsh stimulated the differentiating proliferation of type A undifferentiated spermatogonia (
