The postnatal development of the human cardiac ventricles
… to point out the difference between foetal and postnatal conditions of the heart and great vessels. Harvey, however, was not particularly concerned with the problems of the foetal circulation, and devoted only a passing glance to the subject, using foetal conditions to illustrate his general …

Defining Epithelial Cell Fate Dynamics of the Oesophagus during Postnatal Development and Homeostasis
… response to situations away from homeostasis. Postnatal development provides an ideal physiological model of rapid but restricted tissue growth, in which cells switch from a state of expansion to the steady state of homeostasis. In this project, I investigated the cellular and molecular …

Epithelial and immune cell dynamics in non-traditional models of mammary postnatal development
… each distinct epithelial compartment to mammary postnatal development and the mammary microenvironment remains to be elucidated. The present study aims to exploit the ovine and rabbit mammary gland to interrogate epithelial proliferation and immune cell dynamics during mammary postnatal …

Postnatal development of the somatosensory cortex in a rat model of Fragile X Syndrome
… of how cortical dysfunction arises during development. In this thesis, I examined the first 4 weeks of postnatal development of the somatosensory cortex (S1) in a rat model of FXS, by characterizing the electrophysiological properties and morphology of S1 neurons, combined with an …

Functional profiles of growth-related genes during embryogenesis and postnatal development of chicken and mouse skeletal muscle
… gene expressions during chicken embryonic development. Strong myostatin expression was found in the early chicken embryos (E 0, E 1) and the developmental expression pattern of myostatin mRNA coincided with the periods of primary and secondary muscle fiber formation. Follistatin transcripts …

Modulation of calcium channel expression in cardiac myocytes of rats during growth hormone-induced growth or normal postnatal development
… channels may have some role in embryonic/postnatal development in certain tissues. L-type Ca$\sp{2+}$ channels are regulated in a different way. In contrast to T-type Ca$\sp{2+}$ current, L-type Ca$\sp{2+}$ current density remains constant in both atrial and ventricular cells from rats …

Postnatal development of brainstem cholinergic inputs to the dorsal lateral geniculate nucleus of the domesticated ferret, Mustela putorius furo
… periods of retinal afferent segregation during postnatal development. The first establishes the eye-specific laminae, A and A 1, and the second establishes ON/OFF sublaminae within laminae A and At. In contrast to eyespecific segregation, which seems to rely only on presynaptic activity, ON /OFF …

Modified postnatal social experience alters intersensory development of bobwhite quail chicks
… virginianus), to explore 1) what types of postnatal social experience young chicks require to successfully pair sights and sounds and 2) when these experiences need to occur to maintain species-typical intersensory development. Specifically, chicks in this study were reared in one of four …

The Role of ERK5 in Dopamine Neuronal Survival
… (STR), and ventral tegmental area (VTA) during postnatal development and normal aging using western blot analysis. An age-related decrease in phosphorylated/activated ERK5 (p-ERK5) was observed in the SN and STR, whereas an increase in total ERK1 was observed in all three regions. Higher …

Type and amount of prenatal auditory experience alters postnatal perceptual responsiveness in bobwhite quail

DYNAMIC BEHAVIOR AND LINEAGE PLASTICITY OF THE PULMONARY VENOUS ENDOTHELIUM
… cells to angiogenesis were examined during postnatal development, adult viral injury, and adult hyperoxia injury. Remarkably, we observed that venous endothelial cells proliferate into the adjacent capillary bed upon influenza injury and hyperoxia injury, but not during normal postnatal …

Variation in postpartum maternal care programs the development of neuroendocrine and mesolimbic dopamine pathways in female offspring
… experience high levels of LG (High LG) during postnatal development typically themselves become High LG dams, and females that experience low levels of LG become Low LG dams. Experience of high maternal LG also predicts elevated estrogen receptor-alpha (ERalpha) and oxytocin receptor levels in …

Auditory-Visual System Interactions: Perinatal Visual Experience Affects Auditory Learning and Memory in Bobwhite Quail Chicks (Colinus virginianus)
… emergent sensory systems throughout prenatal and postnatal development. It has also been shown that young infants can learn perceptual information during perinatal development. However, the exact nature of the relationship between prenatal and postnatal perceptual development and the role of early …

Expression of Apolipoprotein E Receptor 2 (ApoER2) and Very Low Density Lipoprotein Receptor (VLDLR), Reelin Receptors in Development of Cerebellar Cortex
During brain development, reelin, an extracellular matrix protein regulates neuronal migration in the cerebral cortex, hippocampus, cerebellum and many other regions of mammalian brain. In the cortex, reelin is secreted by cajal-Retzius cells in the developing marginal zone and is required for …

Influence of Thyroid Hormonal Status on Gene Expression for Calcium Channels in the Developing Olfactory Bulb and Cerebellum of the Postnatal Rat
… genes is differentially regulated. In terms of development, the expression is tied more closely to development in the cerebellum than in the olfactory bulb. While expression appears to be regulated developmentally and by thyroid hormones, the effects are varied depending on both the tissue and …
