Sufu In Shh Signalling Mediated Myogenesis, Suleyman Abdullah

Electronic Thesis and Dissertation Repository

Myogenesis is defined as the formation of skeletal muscle tissue during embryonic development and involves a multitude of cellular signalling pathways. Among these include the Sonic hedgehog (Shh) signalling pathway which must be deactivated for differentiation into muscle cells to occur. However, less is known regarding the pathways operation during cell differentiation and whether Suppressor of Fused (SUFU), the protein inhibitor of Shh signalling, plays a role. To address this, mouse C2C12 myoblast cells were utilized as a model and differentiated into muscle cells to identify the presence of SUFU during this time. Experiments in qRT-PCR show a decrease in …

Age Impacts Perineuronal Net Density In The Somatosensory Genital Cortex Independently Of Gonadal Steroid Hormones, Ian D. Warren

Masters Theses

A hallmark of pubertal development is the rise in gonadal hormone secretions and the subsequent onset of sexual behavior. The size of the somatosensory genital cortex increases in response to both this rise in gonadal steroid hormones and sexual experience. However, whether specific markers of brain plasticity are similarly impacted by gonadal hormones during puberty is not known. Perineuronal nets (PNNs) are specialized extracellular matrix structures that unsheathe neurons as they mature, and their maturation coincides with the closure of sensitive periods across several sensory systems. PNNs in somatosensory cortex, as an example, respond to experience-dependent plasticity. Although experience-depended changes …

Investigating Task-Free Functional Connectivity Patterns In Newborns Using Functional Near-Infrared Spectroscopy, Homa Vahidi

Electronic Thesis and Dissertation Repository

Robust functional connectivity in sensorimotor resting-state network (RSN) has been linked to positive neurodevelopmental outcomes in neonates. In the current study, we aimed to map the developmental trajectory of sensorimotor RSN in awake neonates using functional near-infrared spectroscopy (fNIRS). We acquired fNIRS resting-state data from 41 healthy newborns (17 females, gestational age range=36+0 to 42+1 weeks) within the first 48 hours after birth. At the group level, we observed robust positive connectivity in numerous channel-pairs across the sensorimotor network, especially in the left hemisphere.

Essays On International Trade And Economic Growth, Mateo Hoyos

Doctoral Dissertations

In this dissertation I study the relationship between trade and economic growth, with a focus on developing economies. I specifically provide a critical review of the consensus view in trade and growth, according to which a liberal trade regime is generally the best policy stance to promote growth. In the first essay of this dissertation, I provide evidence that the relationship between trade policy and growth may depend on economic structure: tariff reductions are followed by higher levels of GDP per capita for manufacturer countries, but lower levels for nonmanufacturers. Testing for mechanisms, I find the heterogeneity seems to be …

The Impacts Of Embryo Development And Asynchronous Hatching On Morphology, Growth, And Development Of Larval Burbot (Lota Lota)., Andrew J. Shapiro

All NMU Master's Theses

Burbot (Lota lota) are native fish in Lake Superior and typically spawn during the winter under the ice or by migrating up rivers. The early life history of larval burbot, where they dispurse, how fast they develop, and what their survival rates have not been extensively studied. Asynchronous hatching is a strategy used by other cod species as a bet-hedging strategy to ensure that some larvae are hatched in more advantageous conditions in a varying environment. Asynchronous hatching has been documented in burbot, but the extent of the period and the impacts that asynchrony has on the development of …

Floodplain And In-Channel Sedimentation In The Bedrock Congaree River, Sc, Mahsa Ahmadpoor

Theses and Dissertations

The Congaree River planform is characterized by an abrupt increase in channel sinuosity in the downstream direction. Such a change is not typical of alluvial meandering rivers but has been observed in mixed bedrock-alluvial rivers. This motivated the first study of this dissertation, specifically designed to determine if the Congaree River is indeed a mixed bedrock-alluvial river in its low sinuosity (upstream) reach. To test this hypothesis, sonar-based measurements of channel bed and sublayer elevation were performed from Columbia to the Congaree River-Wateree River confluence. The sublayer is here defined as the first surface visible in the sonar measurements underneath …

Water-Fat Magnetic Resonance Imaging For The Assessment Of Human Fetal Adipose Tissue, Stephanie A. Giza

Electronic Thesis and Dissertation Repository

Adipose tissue is crucial for providing heat and energy to infants, especially at transitions such as birth and therefore must begin developing in utero. This development may be altered due to an adverse uterine environment, increasing the risk of developing later-life metabolic diseases such as obesity. An early assessment of fetal adipose tissue development through lipid accumulation could be key to understanding metabolic programming and minimizing this risk.

Water-fat magnetic resonance imaging (MRI) can non-invasively measure the lipid concentration of tissues and can therefore monitor the development of adipose tissue via tissue lipid concentration. This work demonstrated the feasibility …

Autism, Comorbidities, And Adaptive Functioning: A Potential Moderator, Joshua J. Montrenes

LSU Doctoral Dissertations

Deficits in adaptive functioning and the presence of comorbid symptomatology are both commonly associated with autism spectrum disorder (ASD). Previous research has identified relationships between functional level (e.g., intellectual quotient [IQ], adaptive functioning [AF]) and comorbid symptomatology in ASD. However, further insight into the relationship between AF, comorbid psychopathology, and ASD is unclear. Specifically, how AF affects the relationship between ASD and comorbid conditions is not well understood. Whether AF moderates the relationship between autism symptom severity and comorbid symptom severity in toddlers with ASD was examined. ASD symptom severity positively correlated with comorbid symptom severity across domains and negatively …

Southern Sea Otter (Enhydra Lutris Nereis) Fur Morphology, Thermal Function, And Buoyancy Across Ontogeny, Kate Riordan

Master's Theses

Sea otters (Enhydra lutris) have the densest fur of any animal, and the hairs function to trap a layer of air that is used for insulation. When a sea otter is born, it has a natal pelage (baby fur), and sea otters eventually molt that fur and replace it with a pelt resembling the adult fur. Sea otter fur is composed of 3 types of hairs: underhairs, intermediate hairs, and guard hairs. Sea otters are more susceptible to the negative effects of oiling from oil spills compared to other marine mammal species because they solely rely on fur …

How Violence Shaped The Next Generation: Intergenerational Impacts Of Abduction In Northern Uganda, Mansi Kalra

Master's Theses

Northern Uganda has long been a major conflict zone, home to countless atrocities at the hands of the terrorist group the Lord’s Resistance Army. Widespread kidnappings occurred throughout the 1980s into the early 2000s, and today many of these individuals have been able to return to their homes. However, the scope of trauma does not end when an abductee returns home, it carries on in unpredictable ways and into the lives of family and community members. This brings to question, are the impacts of abduction intergenerational and can they impact the children of former abductees? This study utilizes survey data …

From Morphogens To Monogamy: The Wnt Pathway’S Role In Monogamy, Demira Jakupovic

Biology Honors Theses

The fish species Amatitlania nigrofasciata, convict cichlids, exhibit the behavior of serial monogamy. Dopamine has been linked to the success of pair bonding and monogamy. Dopaminergic (DA) neurons, the receptors of dopamine, are the reason the reward feeling of dopamine is felt by organisms. These neurons are housed in the Ventral Tegmental Area (VTA). The Wnt morphogen, which works through the Wnt pathway, has been previously shown to be a key player in the formation of the midbrain, the area where the VTA resides. This thesis delves into comparing gene expression related to the Wnt morphogen between convict cichlids and …

Seasonal Plasticity And Correlations Among Butterfly Wing Color Patterns: Insights Into Modularity, Rachel Lynn Urban

Undergraduate Honors Thesis Collection

Dealing with the wide ranges of temperatures throughout the year can be a challenge for ectothermic animals like insects. Phenotypic plasticity, the development of different phenotypes depending on the environment, is one way that animals can combat this problem. However, traits are often integrated and share developmental or genetic mechanisms which can limit the adaptive response of an individual trait. Modules, groups of traits that vary together but are independent of other traits, often share developmental mechanisms and therefore can facilitate the evolution of these adaptive traits. The seasonally variable melanistic wing patterns elements of the Colias butterfly are an …
