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 ...

Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

Journal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Narcolepsy and rapid eye movement sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

A Testicular Leydig Cell Tumor; An Uncommon Cause of Precocious Puberty: A Case Report With Secondary Central Precocious Puberty

Acta Medica Iranica, 2023
Sexual precocity in boys is defined as any sign of secondary sexual characteristics present before the age of 9. Leydig cell tumors of the testes are a rare cause of peripheral precocious puberty in boys.

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

Pacing and Clinical Electrophysiology, EarlyView.
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.

Health and Development of Children Born Moderate and Late Preterm and Early Term at Age 10 in French Birth Cohorts ELFE and EPIPAGE 2

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Lower gestational age (GA) is linked to higher mortality and morbidity. Long‐term health and developmental difficulties of individuals born moderate (MPT, 32–33 GA) and late (LPT, 34–36 GA) preterm, and early term (ET, 37–38 GA) are less explored than those of their very preterm peers.

PRECOCIOUS PUBERTY

Ginekologia polska, 2011
Precocious puberty is an early sexual maturation before the age of 8 in case of girls and 9 in boys. There are two types: isosexual precocious puberty--characteristic are appropriate for the child's genetic and gonadal sex; and heterosexual precocious puberty--sexual characteristic are inappropriate for the genetic sex (feminizing syndrome in boys or ...
