Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Endocrine disruptors and abnormalities of pubertal development [PDF]

open access: yes, 2008
Onset and development of puberty is regulated by the neuroendocrine system. Population-based studies worldwide have observed secular trends towards earlier puberty development. These changes are apparently caused by environmental factors such as improved

Adverse Childhood Experiences in Autistic and Neurotypical Girls

open access: yesAutism Research, EarlyView.
ABSTRACT Adverse childhood experiences (ACEs) are potentially traumatic, life‐altering events that occur in childhood with long‐term negative physical and/or mental health outcomes. Previous research, while limited and largely focused on males, suggests children with autism spectrum disorder (ASD) are at higher risk of experiencing ACEs than typically ...

Genetic relationship between growth and reproductive traits in Nellore cattle

open access: yesAnimal, 2012
The objective of this study was to evaluate the genetic relationship between postweaning weight gain (PWG), heifer pregnancy (HP), scrotal circumference (SC) at 18 months of age, stayability at 6 years of age (STAY) and finishing visual score at 18 ...

Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Developmental Milestones for Children With Down Syndrome: Revised Estimates Using Moving Average Summaries

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Children with Down syndrome follow distinct developmental trajectories that require specialized monitoring and counseling. We aimed to provide updated estimates of developmental milestone attainment using a nonparametric approach and to compare these results with previously reported generalized linear mixed‐effects model (GLMM ...

Efeito da idade de exposição de novilhas à reprodução sobre estimativas de herdabilidade da idade ao primeiro parto em bovinos Nelore Effect of age of exposure of heifers to reproduction on heritability estimates for age at first calving in Nelore cattle

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2004
Estimou-se a herdabilidade da idade ao primeiro parto (IPP) a partir de quatro conjuntos com diferentes tipos de informação. A primeira estimativa (IPP1) foi realizada com as novilhas (n= 6.222) expostas apenas na estação "normal", ou seja, aos 24 meses ...

Role of SoxE transcription factors in development and disease

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.
