Biophysical Adaptations Of Collective Cell Migration Through Multiscale Obstructions And Collagen Fibers In Extracellular Matrices, Ye Lim Lee

McKelvey School of Engineering Graduate Student Theses & Dissertations

Collective cell migration is a multiscale process, regulated by mechanosensitive proteins, adhesions between cells and with the extracellular matrix (ECM), and force propagation across length scales. The collective cell migration occurs as the cells receive the mechanical stimuli from the extracellular matrix and respond by generating forces to migrate. This behavior is widely observed in biological processes such as wound repair, angiogenesis, and pathogenic events like cancer metastasis and adipose tissue dysfunction. In these processes, cells often encounter heterogeneous topologies that disrupt and alter collective migration, yet it remains unclear how changes in matrix topology affect migration speed and cell-cell …

Spatiotemporal Patterns In Orbicella Faveolata Wound Regeneration As An Indicator Of Colony Health, Alexander G. Wheeler

All HCAS Student Capstones, Theses, and Dissertations

Anthropogenic (e.g. damage from anchors, scuba divers, tissue sampling) and natural disturbances (e.g. predation, storm damage) can result in wounding of live tissue on coral colonies. Wounding has been shown to detract from a common resource pool, increasing disease susceptibility and impairing coral growth and reproductive activity. Regeneration not only varies between species, but also between conspecifics in the same location. A colony’s capacity to regenerate tissue can be an indicator of a colony’s condition and resilience. Understanding the physiological and environmental factors that affect tissue regeneration alongside the ultimate impact of sampling (disease and predation correlations) are needed for …

2020-Current year OA Pubs

Inferring the intentions and emotions of others from behavior is crucial for social cognition. While neuroimaging studies have identified brain regions involved in social inference, it remains unknown whether performing social inference is an abstract computation that generalizes across different stimulus categories or is specific to certain stimulus domain. We recorded single-neuron activity from the medial temporal lobe (MTL) and the medial frontal cortex (MFC) in neurosurgical patients performing different types of inferences from images of faces, hands, and natural scenes. Our findings indicate distinct neuron populations in both regions encoding inference type for social (faces, hands) and nonsocial (scenes) …

ABSTRACT

Mindfulness Matters: Addressing Anxiety and Navigating Toward Wellbeing Through MIEA Mindfulness Practices, a Mixed-Methods Study of LGBTIQ Graduate Writing Students

Anxiety has always been a part of the human experience, even before the phenomenon was conceptualized in the 17^th century and named by Freud in the 19th. And human beings have devised many strategies for addressing anxiety: reducing it, ignoring it, distracting oneself from it, despairing over it, medicating it, engaging with it, moving through it, co-existing with it. The current zeitgeist, more than four years into the COVID-19 global pandemic, situates anxiety as a central facet of …
