Central precocious puberty secondary to peripheral precocious puberty due to a pineal germ cell tumor: a case and review of literature

BMC Endocrine Disorders, 2023
Background The pineal lesion affecting melatonin is a rare cause of central precocious puberty by decreasing the inhibition of hypothalamic–pituitary–gonadal axis.

Changes in sleep patterns in adolescents are more associated with pubertal indicators than age: A perfect storm with a dash of hormones

British Journal of Developmental Psychology, EarlyView.
Abstract As they become older, adolescents tend to prefer sleeping and rising later. Yet, it is still unclear if these sleep changes occur due to advancing age or because adolescents are more pubertally mature. This was investigated cross‐sectionally in a sample of 121 Brazilian 9‐to‐17‐year‐olds.

Substance P regulates puberty onset and fertility in the female mouse [PDF]

, 2015
Puberty is a tightly regulated process that leads to reproductive capacity. Kiss1 neurons are crucial in this process by stimulating GnRH, yet how Kiss1 neurons are regulated remains unknown. Substance P (SP), an important neuropeptide in pain perception,

Long‐term outcomes of stereotactic radiofrequency ablation in hypothalamic hamartomas: A single‐center experience

Epilepsia, EarlyView.
Abstract Objective Hypothalamic hamartomas (HHs) lead to refractory epilepsy, and minimally invasive surgical approaches are standard of care for affected patients. Stereotactic radiofrequency thermocoagulation (SRT) is one of the treatment methods recognized to achieve seizure freedom. This study reports surgical outcome from a single center reporting

Association of Prenatal Urinary Concentrations of Phthalates and Bisphenol A and Pubertal Timing in Boys and Girls. [PDF]

, 2018
BackgroundAnimal studies suggest that phthalates and bisphenol A (BPA), endocrine-disrupting chemicals found in many consumer products, may impact the timing of puberty.ObjectivesWe aimed to determine the association of prenatal exposure to high ...

Stayability in the Era of Early‐Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...

A reduction in long-term spatial memory persists after discontinuation of peripubertal GnRH agonist treatment in sheep [PDF]

, 2017
Chronic gonadotropin-releasing hormone agonist (GnRHa) administration is used where suppression of hypothalamic-pituitary-gonadal axis activity is beneficial, such as steroid-dependent cancers, early onset gender dysphoria, central precocious puberty and

Genetic Parameters for Novel Feedlot Profitability‐Related Traits in Nelore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate (co)variance components and genetic parameters for accumulated profitability (AFP) and profit per kilogram of liveweight gain (PFT), and their relationships with weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at first calving (AFC), probability of precocious calving at 30 ...
