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

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 422-430, May 2026.
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 ...

Xenoestrogens Ethinyl Estradiol and Zearalenone Cause Precocious Puberty in Female Rats via Central Kisspeptin Signaling [PDF]

, 2015
Xenoestrogens from synthetic or natural origin represent an increasing risk of disrupted endocrine functions including the physiological activity of the hypothalamo-pituitary-gonad axis.

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

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 411-421, May 2026.
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 ...

Gut flora influences the hypothalamic-gonadal axis to regulate the pathogenesis of obesity-associated precocious puberty

Scientific Reports
The prevalence of obesity-associated precocious puberty is gradually increasing, but the relationship between gut flora and obesity-associated precocious puberty remains unclear.We analysed the gut flora characteristics of a clinical sample of 30 girls ...

Transjugular Leadless Pacemaker Implantation in an Adolescent With Central Hypoventilation Syndrome: A Case Report

Pacing and Clinical Electrophysiology, Volume 49, Issue 5, Page 606-609, May 2026.
ABSTRACT Background Permanent pacing in pediatric patients is complicated by small body size, vascular access limitations, and the need for durable long‐term management. Leadless pacemakers offer an emerging alternative that minimizes infection and lead‐related complications, yet vascular access remains a key challenge in young patients.

Serum vitamin D levels in girls with central precocious puberty

Pharmaceutical and Biomedical Research, 2018
Precocious puberty can cause several adverse effects on final growth and social behavior in girls. Recent studies showed that low serum level of vitamin D might be associated with precocious puberty.
