Ethnic Disparities In Thoracic Aortic Dissection And Rupture: A Retrospective Analysis Of Hispanic And Non-Hispanic White Populations, Manuel Gutierrez
Ethnic Disparities In Thoracic Aortic Dissection And Rupture: A Retrospective Analysis Of Hispanic And Non-Hispanic White Populations, Manuel Gutierrez
Yale School of Medicine Physician Associate Program Theses
Background: Aortic dissections and ruptures are even more strongly life-threatening events for patients who are unable to access care promptly. A dissection can reach 50% mortality rate within 24 hours, and a rupture may exceed 90%. Risk factors such as hypertension, genetics, and age play a role in the development of these events; however, few studies have explored whether marginalized groups, such as Hispanics, experience aortic events more frequently. The primary objective of this investigation is to determine whether there is a difference in the frequency of thoracic aortic dissections or ruptures driven by ethnicity in patients from the Yale …

A Computational Framework For Multi-Scale Analysis Of Mouse Cerebral Blood Flow Regulation, Hadi Esfandi
A Computational Framework For Multi-Scale Analysis Of Mouse Cerebral Blood Flow Regulation, Hadi Esfandi
Electronic Theses and Dissertations 2020 - Present
Cerebral hemodynamic imaging is increasingly used as a non-invasive technique to study brain function and dysfunction in both research and clinical settings. Recent advances in imaging technologies have enabled high-speed, high-resolution, whole-brain measurements of blood flow and oxygenation. Improving the interpretation of these cerebral hemodynamic signals through a mechanistic understanding of their cellular drivers would enable more accurate characterization of brain function and pathology. However, no existing biophysical model fully captures the fine-grained dynamics observed in these signals. This dissertation introduces a biophysically grounded computational framework for multi-scale analysis of the mouse cerebral blood flow regulatory system, which captures mechanistic …

Turkish Journal of Botany
Green cities comprise a variety of habitats subject to different levels of anthropogenic pressure, ranging from completely unvegetated areas to vast green spaces such as linear parks. In this scenario, cities can support different ecological processes and ecosystem functions, which vary qualitatively and quantitatively between different habitat types along the urbanization gradient. Specifically, green spaces and ruderal plants can support pollination services in urban ecosystems, providing food resources (e.g., nectar, pollen, oil), reproduction supports (copulation sites), and nesting sites for pollinators. As a result, plant species and their floral resources are important for pollinator diversity and the maintenance of the …

Editorial: Molecular Mechanisms Of Ion Channel Activation And Modulation, Meng Cui, Miao Zhang
Pharmacy Faculty Articles and Research
"Ion channels are integral membrane proteins that regulate the passage of ions across cell membranes, thereby shaping processes as diverse as neuronal signaling, muscle contraction, and hormone secretion. Channel activation is typically initiated by a stimulus such as voltage, ligand binding, or mechanical stress that induces conformational changes and opens the channel pore. Beyond activation, channels are subject to fine-tuned modulation by a wide range of endogenous and exogenous agents, from lipids and neurotransmitters to pharmacological drugs. Modulators can stabilize the open, closed, or inactivated states, shift ligand affinities, or alter gating kinetics. Dissecting the structural and dynamic basis of …
Investigating The Role Of Chaperones And Sequestrases In Misfolded Protein Sequestration, Sarah Rose Rolli
Investigating The Role Of Chaperones And Sequestrases In Misfolded Protein Sequestration, Sarah Rose Rolli
Dissertations (1934 -)
Protein homeostasis, or proteostasis, is responsible for a folded and functional proteome and is essential for cell survival. Proteins can misfold during stress or because of mutation. The accumulation of misfolded proteins is observed in many diseases, including Huntington’s disease. Misfolded proteins will clump together into inclusions, which can be sequestered to membrane-less compartments by proteostasis mechanisms. Several proteins, including chaperones, co-chaperones, and other proteins, have been identified as sequestrases that target inclusions and misfolded proteins to different protein quality control (PQC) compartments. The juxtanuclear quality control (JUNQ) compartment forms in the nucleus-vacuole junction in yeast cells, and several soluble …

Myosin-X (MYO10) is an actin-based motor protein involved in cytoskeletal dynamics, membrane interactions, and integrin-mediated adhesion. To investigate MYO10's cellular roles, we generated MYO10 knockdown (MYO10KD) HeLa and COS7 cell lines using lentiviral shRNA. Compared to wild-type cells, both MYO10KD lines showed reduced proliferation and impaired cell migration in wound assays. Additionally, there were fewer edge filopodia in HeLa cells. Furthermore, MYO10KD cells demonstrated increased spreading on laminin-coated substrates, suggesting altered integrin activation and cytoskeletal linkage. Our results reinforce MYO10’s importance in cell proliferation, adhesion, and migration. These MYO10KD lines provide an accessible cell culture model for future study of …

Ground-Based Modeling Of Deep-Space Risks To The Spleen And Intestine In Mice, Edith Nathalie Pineda Sotomayor
Theses and Dissertations
Deep-space missions, such as those planned for the cis-lunar space and Mars, pose unique challenges to astronaut health due to prolonged microgravity (MG) exposure and low-dose chronic irradiation (CIR). Understanding the impact of these stressors on secondary lymphoid tissues, such as the spleen and intestine, is crucial for ensuring crewmembers' well-being, given the impracticality of conducting this research with human samples. Using a ground-based facility, we exposed C57BL/6 female and male mice to CIR (1.74 Gy at a dose rate of 0.0029 Gy/h) and/or simulated MG (SMG) via hind limb unloading (HLU) for one month. Spleen and intestinal tissues were …

Introduction: Ischemia-induced retinopathies, such as retinopathy of prematurity and proliferative diabetic retinopathy, are major causes of vision loss. Both pathological neovascularization and neuronal damage contribute to vision impairment in these conditions, yet current therapies primarily target neovascularization and may further compromise neuronal health.
Objectives: Cyclic AMP (cAMP) is a widely recognized second messenger regulating diverse physiological and pathological processes. Exchange protein directly activated by cAMP (Epac) is a recently identified effector of cAMP signaling. This study aimed to investigate the role of Epac1 in ischemia-induced retinopathy and elucidate its underlying mechanisms using a mouse model of oxygen-induced retinopathy (OIR).

Two Essays On Health And Health Behavior In China, Jiamin Tan
Two Essays On Health And Health Behavior In China, Jiamin Tan
Lingnan Theses (MPhil & PhD)
This thesis consists of two empirical studies on elderly mental health and on health behaviors. The first study investigates the long-term impact of childhood hunger on mental health in later life, using data from two nationally representative surveys in China. The study finds that childhood hunger exposure significantly increases the risks of depression and anxiety in later life. These effects are most pronounced among individuals exposed after age 5, suggesting that autobiographical memory formation plays an important role beyond socioeconomic and health pathways. The findings further indicate these impacts can be mitigated through economic interventions, such as welfare programs, and …

Student Publications
N6-methyladenosine (m6A) is the most prevalent internal modification in eukaryotic messenger RNA (mRNA) and plays a vital role in post-transcriptional gene regulation. In recent years, m6A has emerged as a pivotal epitranscriptomic signal involved in neural development, synaptic remodeling, and the molecular pathophysiology of neuropsychiatric disorders. In this review, we summarize the mechanisms underlying the deposition, removal, and recognition of m6A by dedicated methyltransferases, demethylases, and RNA-binding proteins. We further explore how these dynamic modifications influence neuronal differentiation and memory formation. Recent studies have linked aberrant m6A regulation to psychiatric …

Light-gated ion channels from protists (channelrhodopsins or ChRs) are optogenetic tools widely used for controlling neurons and cardiomyocytes. Multiplex optogenetic applications require spectrally separated molecules, which are difficult to engineer without disrupting channel function. Scanning numerous sequence databases, we identified three naturally blue-shifted ChRs from ancyromonads. They form a separate branch on the phylogenetic tree and contain residue motifs characteristic of anion ChRs (ACRs). However, only two conduct chloride, whereas the closely related Nutomonas longa homolog generates inward cation currents in mammalian cells under physiological conditions, significantly exceeding those by previously known tools with similar spectral maxima (peak absorption at …

The global reliance on fossil fuels and natural gas has largely dominated the energy production field, but due to finite resource depletion and escalating greenhouse gas emissions, the immediate exploration of sustainable energy alternatives to mitigate climate change and ensure resource security has been a major concern. There has been extensive research into other more renewable methods of energy production, such as wind and hydropower. Of these current energy generation types, there are many areas of untapped potential from the mechanical movements generated ambiently not only in the large scale of power generation but also on a smaller scale. The …

MraY is an essential bacterial enzyme for peptidoglycan synthesis in cell walls and serves as a promising but unrealized target for developing effective antibacterial drugs. Nature has provided a remarkable array of nucleoside inhibitors of MraY, and researchers have skillfully refined these structures to develop inhibitors that effectively mimic natural products. Yet, both natural products and their synthetic variants often face challenges regarding inadequate
