Evolutionary Relationship between Life History and Brain Growth in Anthropoid Primates
… rate is allows individuals to prolong their growth period and reproduce slowly. This theory assumes that growth rates are constant across species, and thus body size is determined by mortality rates.</p><p>This project posits that the intrinsic characteristics of species set the pace of life …

From brain development to reproductive axis: an integrated study of the nervous system in cartilaginous fish
… neurobiology, particularly regarding postnatal brain development, habitat-related brain organization, and the neuroendocrine control of reproduction. A critical review of the literature identified three main knowledge gaps: (i) the scarcity of allometric data on postnatal brain development in …

Longitudinal assessment of the impact of preterm birth on cognitive functions and identification of novel methods for stratification of children at risk of long-term impairment
… of preterm birth are at increased risk of brain maldevelopment, and subsequent neurodevelopmental deficits compared to their term-born peers. Given that neurodevelopmental trajectories are amenable to early interventions, there is a critical window of opportunity to improve long-term …

The Role of Movement in the Classroom
… During this time there is a large amount of brain growth and development. The basis for a healthy life style is, in part, built during this influential period in a child’s life. Additionally, physical activity can increase cognition and psychosocial health in children. The recommended …

Use of Brain Function Concepts by Social Studies Teachers
… in the study was the degree to which selected brain-function concepts had been applied to teaching techniques by Des Moines area secondary social studies teachers who responded to an opinionnaire. These were three primary questions: (1) How aware were respondent teachers of the selected …

Prenatal Cardiovascular Physiology and Early Neurodevelopment in Cyanotic Congenital Heart Disease
… Studies have demonstrated delays in brain growth and maturation begin as early as the third trimester, with correlations to early neurodevelopmental outcomes. These disturbances have been linked to disruptions in cerebral oxygenation due to the abnormal cardiac connections and …

EFFECT OF DIETARY GLYCOMACROPEPTIDE AND CHOLESTEROL ON CORTICAL GANGLIOSIDE- AND GLYCOPROTEIN-BOUND N-ACETYLNEURAMINIC ACID IN YOUNG RATS
… in human milk and accumulate rapidly in the brain during development. Infant formulas contain little sialic acid or cholesterol. Sialic acid and cholesterol supplementation increase cortical ganglioside and glycoprotein sialic acid and cholesterol in animal models, respectively. Doseresponse …

Impact of adult hippocampal neurogenesis on behavior
The role of adult hippocampal neurogenesis in behavior, especially contextual fear conditioning (CFC), is debated. Several studies demonstrated that blocking adult hippocampal neurogenesis in rodents impairs CFC, while several other studies failed to observe impairment. We sought to determine …

The isolation, partial purification and preliminary characterization of a growth factor from chick embryo brains
Chicl( brain growth factor (CBGF) is a mitogen isolated from embryonic chick brains thought to have a potential role as a trophic factor involved in nerve dependent amphibian limb regeneration. In addition, CBGF stimulates 3H-thymidine incorporation in chick embryo brain astrocytes in vitro. In …

Investigating novel direct Notch targets in Drosophila neural stem cells
… differentiate into all kinds of cells within the brain while they self-renew. Notch signalling is one of the key regulators in maintaining NSCs and performs a similar function in both Drosophila and vertebrate NSCs. Drosophila NSCs serve as an ideal model for studying the relationship between …

Distinct Roles for Dynein Regulatory Proteins NudE and NudEL in Brain Development
… Its function is critical for multiple stages of brain development. The dynein regulatory proteins NudE and NudEL have been implicated in several aspects of dynein function, including brain development. Originally identified as nuclear distribution (nud) factors in the dynein pathway, NudE and …

Sex differences in human perinatal development and autism
… in placental angiogenic markers, high placental growth factor (PlGF) and low soluble fms-like tyrosine kinase-1 (sFlt-1) levels, respectively correlated with higher autistic traits in females and an autism diagnosis in males. Chapter 5 describes Studies 4, 5, and 6, all based on a longitudinal …

CNS Neural/Glial Progenitors as Targets of HIV-1 and Opiates: Effects on Proliferation and Population Dynamics May Alter Behavior Outcomes.
… progenitor cells (NPCs) play critical roles in brain growth and repair after injury and insult. Pediatric HIV patients whose glial populations are still developing are especially at risk for central nervous system (CNS) damage. Our previous reports suggest that HIV-1 transactivator of …

The dietary essentiality of n-3 polyunsaturated fatty acids in infant nutrition
… lipid metabolism and perinatal timing of the brain growth spurt to humans, have a lower percentage of 22:6n-3 in blood, liver and CNS tissues when fed formula with 30% of fatty acids as18:2n-6 and 0.8% 18:3n-3, compared to sow milk. It was hypothesized that the low blood and tissue 22:6n-3 in …

Plagiocephaly: Developmental and Medical Outcomes
<p>Plagiocephaly, a condition that is observed by deformation of the head, comes as the result of different etiologies. The most serious involving premature fusion of one or more of the cranial sutures, a condition referred to as craniosynostosis. While children with craniosynostosis may be …

Prenatal influences on fetal neurodevelopment: Can a person-centered approach help parse the complexity of maternal vulnerability and protective features and detect early alterations to fetal neurodevelopment trajectories related to prenatal distress?
… prior to the occurrence of the fetal brain growth spurt hypothesized to fall at 28-32 GW. Second, latent class growth analysis (LCGA) was used to detect subgroups of fetuses who differed from one another in their initial level and/or trajectory of two indices of fetal neurodevelopment …

Effect of Maternal Hypoxia on Fetal Development: Programming of HIE Phenotype in Neonatal Rat Brain
… hypoxia is one of the most common intrauterine growth restricted environment during pregnancy. Perinatal hypoxic-ischemic encephalopathy is an important cause of brain injury in the newborn due to a systematic asphyxia. Our study aims to test the hypothesis that maternal hypoxia affect the …

Cognitive and Language Development in Young Children with Plagiocephaly
<p>Deformational plagiocephaly is a craniofacial condition where the occipital region of an infant’s skull becomes flattened as a result of prenatal or external factors. It is considered to be a primarily cosmetic condition that has no significant long term consequences. A few recent studies, …
