Review of Sexual Maturity in the Minipig [PDF]

open access: yesToxicologic Pathology, 2016
It is important to know whether the animals used in toxicology studies are sexually mature. As minipigs are being used increasingly in toxicity studies, we reviewed published data on the age of sexual maturity in the minipig. Maturity in females was assessed on the basis either of normal cycles of progesterone secretion or of the histological presence ...

Sexual maturation and the adrenal glands [PDF]

open access: yesReproduction, 1978
It is a definite possibility that organs which are primarily elements of functional systems other than the reproductive system are involved in sexual maturation. The adrenal glands are attractive candidates for such a role in sexual maturation: they are capable of producing androgens, oestrogens and progesterone, not only in the adult, but also in the ...

Function and Evolution of Nuclear Receptors in Environmental-Dependent Postembryonic Development

open access: yesFrontiers in Cell and Developmental Biology, 2021
Nuclear receptors (NRs) fulfill key roles in the coordination of postembryonal developmental transitions in animal species. They control the metamorphosis and sexual maturation in virtually all animals and by that the two main environmental-dependent ...

Sex effects on structural maturation of the limbic system and outcomes on emotional regulation during adolescence

open access: yesNeuroImage, 2020
Though adolescence is a time of emerging sex differences in emotions, sex-related differences in the anatomy of the maturing brain has been under-explored over this period.

Zebrafish pituitary gene expression before and after sexual maturation

open access: yes, 2014

Mature Modifications and Sexual Dimorphism [PDF]

open access: yes, 2015
Allometric growth between different parts of the shell often hampers the identification of mollusk shells, particularly in such cases where preadult shell growth varies strongly. Especially in gastropods, the terminal aperture is often less variable and yields morphological information essential for species determination (e.g. Vermeij 1993; Urdy et al.

The use of continuous light to suppress pre-harvest sexual maturation in sea-reared Atlantic salmon (Salmo salar L.) can be reduced to a four month window [PDF]

open access: yes, 2010
In Atlantic salmon Salmo salar L. sexual maturation is concomitant with a redistribution of the somatic resources and the development of nuptial colouration responsible for the low commercial value of mature fish (Michie, 2001).
