Understanding Nanog's Role During Cell Differentiation, Oluwatobiloba Samuel Aminu Jan 2023

Understanding Nanog's Role During Cell Differentiation, Oluwatobiloba Samuel Aminu

Theses and Dissertations

Pluripotency is characterized by the capacity to self-renew and differentiate into all cell types. This state relies on both extrinsic factors, such as leukemia inhibitory factor and bone morphogenetic protein, and intrinsic factors, including pluripotent transcription factors.While the role of pluripotent transcription factors in stem cell maintenance is well understood, their functions beyond pluripotency remain unclear. In this study, we focused on NANOG, a core member of the pluripotency network, and investigated its roles in two different models of differentiation: the transition from the naive to the primed pluripotent state and neuroectodermal differentiation. Our findings demonstrate that NANOG plays a …


A Deep Review Of Sustainable Approaches For Hydrogen Production For Energy Generation, Patrick Bernard Ferron Jan 2023

A Deep Review Of Sustainable Approaches For Hydrogen Production For Energy Generation, Patrick Bernard Ferron

Theses and Dissertations

Fossil fuel energy sources such as coal, oil, and natural gas produce greenhouse gases upon combustion. Over time the greenhouse gases trap heat in the atmosphere and cause global temperatures to continually increase. This continued rise in global temperatures has led to severe climate conditions that have resulted in increasing environmental, financial, social, and medical issues. To mitigate the rise in global temperatures, and the negative effects associated with it, the carbon intensity of our energy sources must be substantially reduced or eliminated where possible. In addition, alternate sources of carbon-free energy sources must be pursued and implemented. Hydrogen is …

A Molecular Phylogeny Of Ctenuchina Kirby, 1837 (Lepidoptera: Erebidae: Arctiinae: Arctiini: Ctenuchina), Sydney Winterton Jan 2023

A Molecular Phylogeny Of Ctenuchina Kirby, 1837 (Lepidoptera: Erebidae: Arctiinae: Arctiini: Ctenuchina), Sydney Winterton

Theses and Dissertations

Ctenuchina are a subtribe of tiger moths in the subfamily Arctiinae and are known for their aposematism and mimicry of noxious insects. Their overall appearance signals predators of their unpalatability due to larval sequestration of plant secondary chemicals. The taxonomic history of Ctenuchina is complicated because of convergent phenotypes within the lineage and with other tiger moth groups such as the Euchromiina. Independent evolutionary events that converge on mimetic phenotypes obscure evolutionary relationships and render classifications based on morphology to be suspect. Although morphological phylogenies have since been used less often in favor of quantifiable, molecular-based phylogenies, these studies provide …

Addressing Interoceptive Awareness In Elementary School Students Affected By Childhood Trauma To Improve Emotional Regulation, Alison O’Sadnick Jan 2023

Addressing Interoceptive Awareness In Elementary School Students Affected By Childhood Trauma To Improve Emotional Regulation, Alison O’Sadnick

Occupational Therapy Capstones

Childhood trauma can affect students’ interoceptive awareness affecting their ability to emotionally regulate within the classroom environment (Neal, 2021). Evidence demonstrates that for students to emotionally regulate, they must have interoceptive awareness (Mahler, 2020). Interoceptive awareness is described as the ability to detect the physiological state of the body such as recognizing signals of respiratory effort, temperature, fatigue, hunger, thirst, satiety, pain, muscle aches, and heart rate (Mahler et al., 2022). Children who have experienced trauma commonly have difficulty identifying and describing internal arousal states, labeling, and expressing emotions and making their needs and wants to be known (Scaffa, 2019).

Fostering A Loving Connection: A Foster Parent’S Toolkit For Understanding And Addressing Behaviors For Children Placed In Out-Of-Home Care, Emily A. Knust

Occupational Therapy Capstones

Children placed in out-of-home care have an 80% chance of having a mental health diagnosis or experiencing negative behaviors related to trauma experiences (Armstrong-Hiemsoth et al., 2020). Children in foster care have been exposed to trauma by being removed from their biological parents and the abuse, neglect, or unsafe conditions that occurred leading up to the removal and placement in out-of-home care (Bartlett, 2021). From this trauma, a child is more likely to experience difficulty with basic self-care skills, executive functioning, emotional regulation, attachment disorders, or positive interactions and relationships within the foster home and their environment (Pervis et al., …


The Impact Of Trauma On Occupational Performance For People Experiencing Homelessness, Isabella Jeanette Johannes Jan 2023

The Impact Of Trauma On Occupational Performance For People Experiencing Homelessness, Isabella Jeanette Johannes

Occupational Therapy Capstones

People transitioning from homelessness experience trauma at three times the risk than the general population (McCurry, 2021). Occupational therapy can provide trauma-informed services that helps people that have experienced homelessness transition to supported housing by addressing occupational competence and identity formation through meaningful activity (McCurry, 2021). Occupational therapy can address this area by educating staff and students that work with this population to be more trauma- informed. It is important to utilize a trauma-informed approach to avoid retraumatization to people that have experienced homelessness (AOTA, 2021). There were two purposes of this project: a) develop advanced knowledge in trauma-informed care, …
