Rare Presentation Of Omental Tuberculosis With Drug-Induced Jaundice In A Teenage Female: A Case Report, Archana Venkatesan, Krishna Ravi

Advances in Clinical Medical Research and Healthcare Delivery

Omental tuberculosis (TB) is a rare form of abdominal TB, often presenting with nonspecific symptoms that mimic malignancies. We report a case of a 16-year-old female from India who presented with abdominal distension, vomiting, weight loss, and amenorrhea. Imaging revealed an abdominal mass, and a diagnosis of omental TB was confirmed via histopathology. This case highlights the diagnostic challenge posed by such atypical presentations, especially in TB-endemic regions. The patient also developed rifampicin-induced jaundice, which resolved upon drug cessation and supportive care. Anti-TB therapy was cautiously reintroduced at a modified dose. This report underscores the need for high clinical suspicion, …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Role Of Evolutionarily Conserved G4 Structures In Enhancer-Promotor Interactions, Shahem Alqudah

Honors Theses

Gene regulation is governed by complex networks of interactions between enhancers and promoters, regions of the genome that are typically distant from one another yet functionally linked through chromatin looping. Recent research has revealed the significant role of Gquadruplexes (G4s) in facilitating these interactions. This thesis explores the role of long Gquadruplex regions (LG4s) in enhancer–promoter communication, proposing that these regions mediate physical interactions between enhancers and their target promoters through direct G4:G4 interactions. Using a chromatin conformation capture (EQuIP-seq), electrophoretic mobility shift assays (EMSA), and luciferase reporter assays, the study demonstrates that LG4s may drive gene expression by promoting …

Role Of Insulin-Like Growth Factor-1 Signaling In Diet-Enhanced Bone Elongation, Cassaundra A. White

Theses, Dissertations and Capstones

Childhood obesity has increased precipitously to the point that almost 20% of children between the ages of 2 and 19 have been diagnosed with obesity. While obesity is a complex metabolic disorder, one contributing factor is diet, particularly a diet high in fat. Among many problems associated with diet-induced obesity, the impact on skeletal health is often overlooked. In addition to increased stress on the skeleton due to excess weight, obesity also disrupts the endocrine and immune systems that, in turn, can secondarily alter skeletal growth. Obesity during the early years of childhood is particularly detrimental because the skeleton is …

Patient-Specific Genome-Scale Metabolic Models For Individualized Predictions Of Liver Disease, Alexandra Manchel, Jan B. Hoek, Ramon Bataller, Radhakrishnan Mahadevan, Rajanikanth Vadigepalli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The prevalence of liver disease is steadily increasing, coupled with the limited availability of therapeutic treatments. Recent literature points to metabolic reprogramming as a key feature of liver failure. Hence, we sought to uncover the metabolic pathways and mechanisms associated with liver disease and acute liver failure. We generated patient-specific genome scale metabolic models by integrating RNA-seq data from patient liver samples with a generalized human metabolic model. Flux balance analysis simulations showed a distinct separation of non-alcohol associated and alcohol-associated disease states. Our analysis suggests that the alcohol associated liver has an increased flux through nucleotide and glycerophospholipid metabolic …

Systematic review methodology is a means of addressing specific questions through structured, consistent, and transparent examinations of the relevant scientific evidence. This methodology has been used to advantage in clinical medicine, and is being adapted for use in other disciplines. Although some applications to toxicology have been explored, especially for hazard identification, the present preparatory study is, to our knowledge, the first attempt to adapt it to the assessment of toxicological test methods. As our test case, we chose the zebrafish embryotoxicity test (ZET) for developmental toxicity and its mammalian counterpart, the standard mammalian prenatal development toxicity study, focusing the …

Contribution Of Animal Models To Contemporary Understanding Of Attention Deficit Hyperactivity Disorder, Constança Carvalho, Mariana Vieira Crespo, Luísa Ferreira Bastos, Andrew Knight, Luís Vincente

Biomedicine and Animal Models in Research Collection

Attention Deficit Hyperactivity Disorder (ADHD) is a poorly understood neurodevelopmental disorder of multifactorial origin. Animal-based research has been used to investigate ADHD etiology, pathogenesis and treatment, but the efficacy of this research for patients has not yet been systematically evaluated. Such evaluation is important given the resource consumption and ethical concerns incurred by animal use.

We used the citation tracking facility within Web of Science to locate citations of original research papers on animal models related to ADHD published prior to 2010 identified in PubMed by relevant search terms. Human medical papers citing those animal studies were carefully analyzed by …

Wasted Money In United States Biomedical And Agricultural Animal Research, Jim Keen

Biomedicine and Animal Models in Research Collection

Biomedical and agricultural animal research uses millions of experimental animals and dozens of animal species each year by choice, precedent, or regulatory mandate in basic and applied life science research and toxicity testing of drugs, chemicals, and consumer products. Animal research is a large component of the international us$270 billion government-subsidized, biomedical industrial ecosystem (Chakma et al., 2014). In the United States (us) and presumably elsewhere, about half of these funds support animal research and testing (Institute of Medicine and National Research Council, 2012). Each year at least 115 million experimental animals (mostly mice and likely a significant underestimate) are …

Defining The Radioresponse Of Mossy Cells, Devon Ivy

Electronic Theses, Projects, and Dissertations

Clinical radiotherapy is used to treat a variety of brain tumors within the central nervous system. While effective, it can result in progressive and debilitating cognitive impairment that can diminish quality of life. These impairments have been linked to hippocampal dysfunction and corresponding deficits in spatial learning and memory. Mossy cells are a major population of excitatory neurons located within the dentate hilus and highly involved in hippocampal circuitry. They play critical roles in spatial navigation, neurogenesis, memory, and are particularly vulnerable to a variety of neurotoxic insults. However, their sensitivity to ionizing radiation has yet to be investigated in …

Spinal Cord Trauma: An Overview Of Normal Structure And Function, Primary And Secondary Mechanisms Of Injury, And Emerging Treatment Modalities, Daniel Morin

Senior Honors Theses

The structures of the spinal cord and vertebral column are designed to provide flexibility, while still providing ample protection for the spinal cord deep within. While it does offer remarkable protection against most routine trauma, the spinal cord is still vulnerable to high-force etiologies of trauma and may become damaged as a result. These events are referred to as primary injury. Following the initial injury, the body’s own physiological responses cause a cascade of deleterious effects, known as secondary injury. Secondary injury is a major therapeutic target in mitigating the effects of spinal cord injury (SCI), and much research is …
