Faculty, Staff and Student Publications

We studied the expression of two hepatocyte nuclear factor 4 alpha (HNF4α) isoforms, p-STAT3. and c-Myc in 49 consecutive liver biopsies with nonalcoholic fatty liver disease (NAFLD) using immunohistochemistry. All 49 biopsies (100%) were positive for nuclear expression of P1-HNF4α. Twenty-eight (57%) cases were positive for P2-HNF4α, 6 (12%) were positive for p-STAT3 and 5 (10%) were positive for c-Myc. All 6 (100%) p-STAT3-positive cases were also positive for P2-HNF4α (p = 0.03). p-STAT3-positive cases were more likely to be positive for c-Myc (67% vs. 2%, p = 0.0003). Four cases were positive for P2-HNF4α, p-STAT3 and c-Myc. p-STAT3 …

A Unified Model Of Age-Related Cardiovascular Disease, Michael Fossel, Joe Bean, Nina Khera, Mikhail G Kolonin

Faculty, Staff and Student Publications

Despite progress in biomedical technologies, cardiovascular disease remains the main cause of mortality. This is at least in part because current clinical interventions do not adequately take into account aging as a driver and are hence aimed at suboptimal targets. To achieve progress, consideration needs to be given to the role of cell aging in disease pathogenesis. We propose a model unifying the fundamental processes underlying most age-associated cardiovascular pathologies. According to this model, cell aging, leading to cell senescence, is responsible for tissue changes leading to age-related cardiovascular disease. This process, occurring due to telomerase inactivation and telomere attrition, …

Managing Tuberculosis In Refugee Populations, Roselyn Fierkens

Senior Honors Theses

Tuberculosis (TB) is an airborne-transmitted infectious disease, responsible for more global deaths than HIV. Multidrug-resistant strains are developing, which heightens the need for swift eradication. Current data states that 71.4% of all TB cases in the United States occur in foreign-born individuals, so populations traveling from TB endemic areas are a key target population for prevention strategies. Various screening procedures exist, but no successful standard is in place. Beyond prevention and treatment strategies, adaptations to cultural communication differences are integral to successful medical interventions. This synthesis of TB pathophysiology, treatments, risk factors, and cultural considerations is intended for use in …

Spontaneous Coronary Artery Dissection Is Infrequent In Individuals With Heritable Thoracic Aortic Disease Despite Partially Shared Genetic Susceptibility, Regina Husman, Akiko Tanaka, S Keisin Wang, Kourosh Keyhani, Arash Keyhani

Faculty, Staff and Student Publications

Spontaneous isolated celiac artery dissection (SICAD) is a rare condition, defined as dissection of the celiac artery without aortic involvement. Because of its low prevalence, most studies have been limited to case reports and case series. We have described the case of a 44-year-old woman who had presented with symptomatic SICAD that had resulted in compromised flow to the hepatic arteries and was successfully treated with balloon angioplasty. Angioplasty alone might be effective for cases of extensive false lumen thrombosis in SICAD for immediate flow restoration to the true lumen, expediting positive remodeling.

Exploring Risk Factors Of Alzheimer’S Disease Using Mouse Models, Xian Han

Theses and Dissertations (ETD)

Mouse models of Alzheimer’s disease (AD) that accurately recapitulate pathology and molecular changes are crucial for understanding disease mechanisms and subsequent therapeutic development. We examined five commonly used mouse models of AD (5xFAD, J20, APPNL-F, APPNL-G-F, Tau P301S) and compared their whole- and phosphoproteomes with human AD (the integration of three published datasets) to study whether they can mimic protein/RNA expression discrepancies, molecular changes, and enriched pathways found in human AD cases. The mouse models especially 5xFAD and APPNL-G-F show proteomic signatures similar to human AD but lack human-specific AD progressions, such as dysregulation of synaptic pathways and networks. Integration …

Non-muscle Invasive Bladder Cancer (NMIBC) accounts for 80% of all bladder cancers. Although it is mostly low-grade tumors, its high recurrence rate necessitates three-times-monthly follow-ups and cystoscopy examinations to detect and prevent its progression. A rapid liquid biopsy-based assay is needed to improve detection and reduce complications from invasive cystoscopy. Here, we present a rapid spectroscopic method to detect the recurrence of NMIBC in urine. Urine samples from previously-diagnosed NMIBC patients (n = 62) were collected during their follow-up visits before cystoscopy examination. Cystoscopy results were recorded (41 cancer-free and 21 recurrence) and attenuated total refraction Fourier transform infrared (ATR-FTIR) …

The Effects Of A Low Fodmap Diet On People With Irritable Bowel Syndrome: A Literature Review, Emily Stalder

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Irritable Bowel Syndrome (IBS) is a very common gastrointestinal disorder around the world. There is no known etiology or cure for the disorder, which leaves researchers to develop coping mechanisms for this prevalent issue. A high percentage (10%-15%) of the general population, mostly in Western, industrialized areas, suffer from IBS. A low FODMAP diet (LFD) is something that has been gaining a following over the past 20 years, which has led to research on its ability to minimize symptoms of IBS. The purpose of this literature review is to see what current research has to offer on the LFD’s ability …

Med12 Is A Critical Regulator Of Neural Crest Lineage And Nervous System Myelination, Fatma Betul Aksoy Yasar

Dissertations and Theses (Open Access)

The Mediator complex (MED) is a multi-subunit protein complex integral to the eukaryotic transcription machinery. MED12 is a Cdk8- regulatory kinase module subunit directly implicated in human disease and is genetically altered in neurological disease and cancer. Numerous attempts at generating an in vivo system to study the role of Med12 failed due to embryonic lethality associated with germline or developmental disruption of Med12 gene. To understand the cellular and molecular processes associated with its role in disease, we generated multiple mouse models with targeted depletion of MED12 in distinct cellular lineages. Our genetically engineered models with induced and conditional …
