Recommendations For Diagnosis And Treatment Of Functional Hypothalamic Amenorrhea In Females Of Reproductive Age, Monica Foster Jan 2025

Recommendations For Diagnosis And Treatment Of Functional Hypothalamic Amenorrhea In Females Of Reproductive Age, Monica Foster

Capstone Showcase

Hypothalamic amenorrhea (HA) accounts for approximately 30% of total cases of secondary amenorrhea in women of reproductive age. HA is defined as the absence of menses due to inadequate secretion of gonadotropin-releasing hormone (GnRH) by the hypothalamus leading to lack of secretion of gonadotropins from the anterior pituitary gland and steroid hormones from the ovaries. This feedback loop, called the hypothalamic-pituitary-gonadal (HPG) axis, regulates reproductive activity in animals and humans. When this system is disrupted in females due to a hormonal imbalance, menstrual abnormalities may emerge. Functional hypothalamic amenorrhea (FHA) is defined as the absence of menses in which anatomic …

Depression remains a significant public health challenge in the U.S., affecting millions of adults and contributing to both psychological and financial burdens. Major depressive disorder impacts approximately 14.5 million U.S. adults, with about 30% of cases classified as treatment-resistant depression. Traditional antidepressant therapies, including selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors, often have delayed onset and limited efficacy, leaving a substantial portion of patients without adequate relief. Given these limitations, there is an urgent need for alternative treatment options.

Recent research has highlighted ketamine as a promising intervention for Major Depressive Disorder and Treatment Resistant Depression. Initially identified as …


Caspases Protect Against Hyperglycemia Induced Necroptosis-Like Cell Death In Brain Endothelial Cells, Aleena S. Mathew Jan 2025

Caspases Protect Against Hyperglycemia Induced Necroptosis-Like Cell Death In Brain Endothelial Cells, Aleena S. Mathew

Theses and Dissertations

Acute diabetes characterized by high spikes in blood glucose levels in association with severe hyperglycemia can lead to an increased risk of ischemic stroke in the brain. To better understand high blood glucose levels, hyperglycemia, in the brain we explored its effects on endothelial cells. Endothelial cells line the inner walls of blood vessels and are directly impacted in hyperglycemia. Brain endothelial cells are a major component of the blood brain barrier (BBB) which tightly regulates the brain’s microenvironment. The type of cell death such as apoptosis, caspase dependent, or necroptosis, caspase independent, can exacerbate diabetes associated complications. There is …


Social Rejection, Isolation, And Substance Use Disorders: A Neurobiological Defense Of Social Network Intervention In Single-Site Housing First, Victoria Eichel Jan 2025

Social Rejection, Isolation, And Substance Use Disorders: A Neurobiological Defense Of Social Network Intervention In Single-Site Housing First, Victoria Eichel

Scripps Senior Theses

Abstract

Introduction: Rising rates of homelessness in the United States demand not only increased housing efforts but also comprehensive strategies addressing the underlying causes of chronic homelessness. Among the most prevalent factors is substance use disorder (SUD), which both contributes to and results from housing instability. Conventional abstinence-based treatment models often fail to address the root causes of substance use, particularly the chronic social isolation and rejection experienced by the unhoused. This thesis argues for the adoption of a neuroscience-informed model of recovery rooted in community reintegration and low-barrier housing with on-site support services.

Combining Internal Family Systems Therapy And Dance Movement Therapy To Treat Survivors Of Sexual Assault, Tierney O'Keefe Jan 2025

Combining Internal Family Systems Therapy And Dance Movement Therapy To Treat Survivors Of Sexual Assault, Tierney O'Keefe

Scripps Senior Theses

The mammalian nervous system is primed to connect with loved ones, flee from danger, and shut down when overwhelmed. The nervous system frequently enters a state of chronic dysregulation after a traumatic event, such as a sexual assault. In order to properly heal from such trauma, treatment must address both the body and the mind. Internal family systems therapy and dance movement therapy provide two frameworks to address nervous system dysregulation and restore balance to the system as a whole. This study combines both therapies into a hybrid therapy treatment as an attempt to address the somatic nature of stored …


Gain-Of-Function Tp53 Mutations Induce Non-Canonical Nf-Κb Transcriptional Targets To Promote Tumor Development, Kelsey A. Yutan Jan 2025

Gain-Of-Function Tp53 Mutations Induce Non-Canonical Nf-Κb Transcriptional Targets To Promote Tumor Development, Kelsey A. Yutan

Scripps Senior Theses

Background: Gain-of-function TP53 mutations have previously been shown to induce chromosomal instability (CIN) in cancer cells, triggering the cGAS-STING innate immune response and subsequently activating the non-canonical NF-κB (NC-NF-κB) signaling pathway. This signaling cascade promotes cancer cell metastasis and an immunosuppressive tumor microenvironment (TME), significantly impacting tumor development and progression. However, the precise downstream mechanisms by which the mutp53-CIN-cGAS-STING-NC-NF-κB signaling pathway facilitates tumor development and progression remain poorly understood. Here, our objective was to identify direct downstream targets of mutp53-CIN-cGAS-STING-induced NC-NF-κB signaling that potentially impact the TME to promote the development and progression of oral squamous cell carcinoma.

Through this process, our pedagogical approaches and professional identities were reshaped, shifting from content deliverers to reflective co-learners within the cross-cultural partnership. Our analysis highlights the interplay of cultural negotiation, logistical frictions, and unspoken yet influential …


Exploring Physicians/Physician Assistants Perspectives On The Challenges And Communication Approaches When Communicating With People With Aphasia, Alexandra M. Rogers Jan 2025

Exploring Physicians/Physician Assistants Perspectives On The Challenges And Communication Approaches When Communicating With People With Aphasia, Alexandra M. Rogers

SURF Posters 2025

Aphasia is an acquired language disorder that results from damage to the language areas of the brain, typically located within the left hemisphere. Individuals with aphasia often experience significant challenges while communicating with other individuals, including physicians and healthcare professionals. These barriers can ultimately lead to negative impacts on the quality of care, patient experiences, and overall health outcomes. The lack of consistent use of communication strategies as well as a general misunderstanding of aphasia by medical staff, further contributes to communication breakdowns. As a result, medical assessments can be misinterpreted, treatments may be delayed, and patients may feel less …

Effects Of Energy Drinks On Crayfish Physiology, Melyna Sweeney

Williams Honors College, Honors Research Projects

Energy drinks have become the drink of choice among many college students due to the rush of energy it provides via the megadose of caffeine (Vercammen et al. 2019). Because of their newfound popularity, there is much research to be done about the effects on human physiology. Energy drinks are known to increase endurance in muscles of rat subjects (Imagawa et al. 2009) and stimulate enhanced “alertness” (Smit & Rogers, 2002). The purpose of this research was to uncover the potential effects that energy drinks have on metabolic rate and/or stress responses in crayfish (Procambarus clarkii), with the …


Astrocyte Specific Enhancers In The Cortex And Striatum Of Mice, Mikaela Kottelich Jan 2025

Astrocyte Specific Enhancers In The Cortex And Striatum Of Mice, Mikaela Kottelich

Williams Honors College, Honors Research Projects

Among glial cells, astrocytes have a prevalent influence on supporting neuronal function and overall brain health. Specifically targeting this cell type for disease treatment is an existing issue. Other cell types tend to express the desired treatment, which is not always wanted and can lead to unintended, negative consequences. Astrocytes contribute largely to maintaining the blood brain barrier, which is disrupted in Parkinson’s disease. Certain genes are thought to be the reason for this disruption, so if they can be specifically targeted in astrocytes with a specific enhancer, the disruption of the disease could be reversed. In our experiment, we …


Impact Of Tetrahydrocannabinol (Thc) On Daphnia Magna Heart Rate, Ashley Cosgrave Jan 2025

Impact Of Tetrahydrocannabinol (Thc) On Daphnia Magna Heart Rate, Ashley Cosgrave

Williams Honors College, Honors Research Projects

Marijuana (Cannabis) is currently federally illegal within the United States and classified as a Schedule I drug. This leaves a large research gap on the impacts of Tetrahydrocannabinol (THC) use. Daphnia magna are frequently used as a model organism for the human heart and toxicology screenings due to their myogenic heart, similarities in physiological pathways, and sensitivity to toxins. As such, in order to bridge the research gap and uncover potential use of Daphnia magna as a model organism for humans in regard to impact on heart rate, we hypothesized that if Daphnia magna possess CB1 receptors or an equivalent …

Neurotensin Regulates Primate Ovulation Via Multiple Neurotensin Receptors, Andrew C. Pearson, Jessica S. Miller, Hannah J. Jensen, Ketan Shrestha, Thomas E. Curry Jr., Diane M. Duffy

Department of Biomedical and Translational Sciences Faculty Publications

Neurotensin (NTS), a small neuropeptide, was recently established as a key paracrine mediator of ovulation. NTS mRNA is highly expressed by granulosa cells in response to the luteinizing hormone (LH) surge, and multiple NTS receptors are expressed by cells of the ovulatory follicle. To identify the role of NTS receptors NTSR1 and SORT1 in ovulation in vivo, the dominant follicle of cynomolgus macaques (Macaca fascicularis) was injected with either vehicle control, the general NTS receptor antagonist SR142948, the NTSR1-selective antagonist SR48692, or the SORT1-selective antagonist AF38469. Human chorionic gonadotropin (hCG) was then administered to initiate ovulatory events. …


Enhancing Trust In Ai For Healthcare: A Quantative Evaluation Of Explainable Methods In Clinical Decision Support Systems, Abdul Aziz Noor Jan 2025

Enhancing Trust In Ai For Healthcare: A Quantative Evaluation Of Explainable Methods In Clinical Decision Support Systems, Abdul Aziz Noor

Masters

The integration of Artificial Intelligence (AI) into healthcare has revolutionized Clinical Decision Support Systems (CDSS) by enabling sophisticated predictive capabilities. However, the opaque nature of many machine learning models, commonly referred to as "black-box" systems, poses significant challenges to their adoption in critical clinical settings where transparency, interpretability, and trust are paramount. This thesis addresses these challenges by developing a rigorous, mathematically grounded framework to evaluate Explainable AI (XAI) methods and enhance their integration into CDSS.
