Changes in Sleep Patterns in Korean Early Adolescents during Sexual Maturation [PDF]

open access: yesAnnals of Child Neurology, 2022
Purpose Teenagers’ sleep patterns show physiological delays influenced by sexual maturation and other external time-related factors. However, Korean adolescents show differences in the onset of pubertal development and have shorter sleep durations than ...

Characterization of N6-Methyladenosine in Domesticated Yak Testes Before and After Sexual Maturity

open access: yesFrontiers in Cell and Developmental Biology, 2021
The potential regulatory role of N6-methyladenosine (m6A), the most prominent mRNA modification in eukaryotes, has recently been identified in mammals, plants, and yeast.

Road to sexual maturity: Behavioral event schedule from eclosion to first mating in each sex of Drosophila melanogaster

open access: yesiScience, 2023
Summary: Animals achieve their first mating through the process of sexual maturation. This study examined the precise and detailed timing of a series of behavioral events, including wing expansion, first feeding, first excretion, and courtship, during ...

Aggregation pheromone 4-vinylanisole promotes the synchrony of sexual maturation in female locusts

open access: yesbioRxiv, 2021
Reproductive synchrony generally occurs in various group-living animals; however, the underlying mechanisms remain largely unexplored. Here, we report that aggregation pheromone, 4-vinylanisole, plays a key role in promoting sexual maturation synchrony ...

Major Transitions in Cuticular Hydrocarbon Expression Coincide with Sexual Maturity in a Blowfly (Diptera: Calliphoridae) [PDF]

open access: yes, 2020
In many animals, there is a prolonged pre-reproductive period prior to sexual maturity. To avoid premature mating attempts, it is common for phenotypic changes to occur during this period that signal the onset of reproductive viability. Among the insects,

Neuroendocrine regulation of reproduction in Atlantic cod (Gadus morhua): Evidence of Eya3 as an integrator of photoperiodic cues and nutritional regulation to initiate sexual maturation [PDF]

open access: yes, 2021
Evidence from mammals and aves alludes to a possibly conserved seasonal photoperiod induced neuroendocrine cascade which stimulates subsequent sexual maturation however our understanding of this mechanism in teleosts is lacking.

Sex differences in the association of measures of sexual maturation to common toxicants: Lead, dichloro-diphenyl-trichloroethane (DDT), dichloro-diphenyl-dichloroethylene (DDE), and polychlorinated biphenyls (PCBs)

open access: yesAnnals of Human Biology, 2021
Many studies of human toxicant exposure examine the hypothesis that human sexual maturation can be affected through endocrine disruption. Within this body of literature there is significant variation in the findings.

An assessment of sexual maturation among school girls in Abakaliki Metropolis, Ebonyi State, South-East Nigeria

open access: yesNigerian Postgraduate Medical Journal, 2016
Background: Sexual maturation is an important milestone which starts between 8 and 14 years in girls. However, varying ages of onset of sexual maturation have been reported in different environments, with more recent studies showing earlier ages of onset

Body-fat sensor triggers ribosome maturation in the steroidogenic gland to initiate sexual maturation in Drosophila [PDF]

open access: yes, 2021
Fat stores are critical for reproductive success and may govern maturation initiation. Here, we report that signaling and sensing fat sufficiency for sexual maturation commitment requires the lipid carrier apolipophorin in fat cells and Sema1a in the ...

Zebrafish pituitary gene expression before and after sexual maturation [PDF]

open access: yes, 2014
Sexual maturation and somatic growth cessation are associated with adolescent development, which is precisely controlled by interconnected neuroendocrine regulatory pathways in the endogenous endocrine system.
