GWAS on early sexual maturation across freshwater and seawater environments in domesticated Lochy strain of Atlantic salmon [PDF]

open access: yesGenetics Selection Evolution
Background Early sexual maturation is a challenging obstacle to overcome in Atlantic salmon farming. This trait primarily affects males and occurs in both freshwater fish farms and sea culture cages during the fattening phase.

Analysis of circular RNA (circRNA) characteristics and identification of key circRNAs in the hypothalamus during sexual maturation in female goats [PDF]

open access: yesAnimal Bioscience
Objective Precocious puberty can shorten reproductive cycles, enhance reproductive capacity, and reduce feeding costs. Consequently, precocious livestock are widely utilized in cross-breeding.

Premature sexual maturation

open access: yes, 2011
Premature sexual maturation is a frequent cause for referral in paediatric endocrinology. Although clinical evaluation will suffice to reassure the patient and family in a majority of cases, premature sexual maturation can reveal severe conditions and ...

Body Mass Index and Sexual Maturation in Adolescent Patients with Sickle Cell Anaemia

open access: yesNigerian Journal of Paediatrics
Background: Sickle cell anaemia (SCA) is associated with delayed sexual maturation. The Body Mass Index (BMI) or Quetelets Index is closely linked to events of puberty in normal children.

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 ...

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.
