Modulating Oran Nitrate-Reducing Bacteria To Enhance Nitric Oxide Bioavailability As A Therapeutic Target For Atherosclerosis, Donovan C. Davidson Jan 2026

Modulating Oran Nitrate-Reducing Bacteria To Enhance Nitric Oxide Bioavailability As A Therapeutic Target For Atherosclerosis, Donovan C. Davidson

CMC Senior Theses

Atherosclerosis remains the primary driver of global cardiovascular disease, yet clinical interventions are largely restricted to high-cost, invasive procedures only after it has reached a critical stage. Recent research has identified a connection between the oral microbiome and vascular health via the enterosalivary nitrate-nitrite-nitic oxide (NO) pathway. Oral nitrate-reducing bacteria (ONRB) drive the synthesization of NO by reducing dietary nitrate into nitrite, which is then converted into bioavailable NO. NO is a potent vasodilator that maintains endothelial health by suppressing inflammation through inhibiting the expression of adhesion molecules VCAM-1 and ICAM-1. However, this pathway is easily compromised by dysbiotic oral …


Characterization Of Dietary And Hormonal Influences On Renal Sodium Transporters And Channels In Rodent Models, Evelyn Chan Jan 2025

Characterization Of Dietary And Hormonal Influences On Renal Sodium Transporters And Channels In Rodent Models, Evelyn Chan

Scripps Senior Theses

Within kidneys, a diverse array of renal epithelial cells works to maintain electrolyte and water balance to regulate blood pressure and pH. These cells contain varying types of sodium transporters that adjust sodium reabsorption according to the body’s needs. Previous studies have observed sex-specific differences in renal sodium transporter regulation, which are thought to optimize reproduction in females. In this study, we performed high resolution microscopy and detailed characterization of cell type-specific expression and localization of major sodium transporters and channels in rodents in response to dietary and hormonal influences. Specifically, we examined the impact of dietary salt intake and …


Physician Assisted Dying (Pad): An Investigation Into The Mechanistic Action Of Opioid, Benzodiazepine, And Barbiturate Administration As An Alternative Measure To Forgoing Life Sustaining Treatment And Aggressive Palliation., Jordana Chanel Deighton Jan 2022

Physician Assisted Dying (Pad): An Investigation Into The Mechanistic Action Of Opioid, Benzodiazepine, And Barbiturate Administration As An Alternative Measure To Forgoing Life Sustaining Treatment And Aggressive Palliation., Jordana Chanel Deighton

CMC Senior Theses

Whilst modern medicine has increased longevity, the rise in life expectancy has brought about new struggles, namely that of aging and age related disease. Thus, humanity has been presented with a new problem: at what point is death preferable to aggressive life-prolonging treatment in the face of inevitable death? And if so, what right do individuals have to control the circumstances of their death? In the West, traditionally, individuals who seek to end their own lives in the face of terminal illness opt for forgoing artificial hydration and nutrition. Driven by an increase in desire for autonomous dignified death, a …


Morphological Changes In Dorsal Root Ganglia Macrophages Associated With Neuropathic Pain Mechanisms Suggest A Novel Target For Chronic Pain Therapy, Emily Kussick Jan 2021

Morphological Changes In Dorsal Root Ganglia Macrophages Associated With Neuropathic Pain Mechanisms Suggest A Novel Target For Chronic Pain Therapy, Emily Kussick

CMC Senior Theses

The present study examined morphological changes in the dorsal root ganglia (DRG) following an innate immune stimulus. The importance of the DRG has increasingly become recognized in pain processing as more than just the home of primary afferent cell bodies. All sensory information passes through the DRG via the primary afferents, and on to the spinal cord. The primary afferents synapse with second-order neurons in the spinal cord that ascend towards the brain, where they transmit the pain signal to the limbic forebrain and/or the somatosensory cortex for processing. The DRG is an interesting niche to study at as it …


A Proposal To Test The Effects Of Factor Ecat1 On Pluripotency, From Reprogramming To Differentiation Of Human Somatic Cells, Vritti R. Goel Jan 2012

A Proposal To Test The Effects Of Factor Ecat1 On Pluripotency, From Reprogramming To Differentiation Of Human Somatic Cells, Vritti R. Goel

CMC Senior Theses

The field of stem cell research has been growing more because of the interest in using stem cells to cure diseases and heal injuries. Human embryonic stem cells, because of the controversy surrounding them—and subsequently the difficulties in acquiring samples of the existing aging cell lines—can only be used in limited capacities. While the development of induced pluripotent stem cells in the last decade has allowed the field to progress closer to medical treatments, the low efficiency of reprogramming a somatic cell to a pluripotent state, and the vast molecular and genomic differences between human embryonic stem cells and human …
