Osteopathic Medicine, Jerry M. Wallace School of

Respiratory syncytial virus (RSV) infection is the major cause of bronchiolitis in young children. The factors that contribute to the increased propensity of RSV-induced distal airway disease compared with other commonly encountered respiratory viruses remain unclear. Here, we identified the RSV-encoded nonstructural 2 (NS2) protein as a viral genetic determinant for initiating RSV-induced distal airway obstruction. Infection of human cartilaginous airway epithelium (HAE) and a hamster model of disease with recombinant respiratory viruses revealed that NS2 promotes shedding of infected epithelial cells, resulting in two consequences of virus infection. First, epithelial cell shedding accelerated the reduction of virus titers, presumably …

Department of Emergency Medicine Faculty Papers

BACKGROUND: Sepsis accounts for 30% to 50% of all in-hospital deaths in the United States. Other than antibiotics and source control, management strategies are largely supportive with fluid resuscitation and respiratory, renal, and circulatory support. Intravenous vitamin C in conjunction with thiamine and hydrocortisone has recently been suggested to improve outcomes in patients with sepsis in a single-center before-and-after study. However, before this therapeutic strategy is adopted, a rigorous assessment of its efficacy is needed.

METHODS: The Vitamin C, Thiamine and Steroids in Sepsis (VICTAS) trial is a prospective, multi-center, double-blind, adaptive sample size, randomized, placebo-controlled trial. It will enroll …

Orthokeratinized Odontogenic Cyst (Ooc): Clinicopathological And Radiological Features Of A Series Of 10 Cases, Nasir Ud Din, Maha Zubair, Jamshid Abdul-Ghafar, Zia Ullah Khan, Zubair Ahmad

Department of Pathology and Laboratory Medicine

Background: Orthokeratinized Odontogenic Cyst (OOC) is a rare, developmental odontogenic cyst which was considered in the past to be a variant of Odontogenic keratocyst (OKC) later renamed as keratocystic odontogenic tumor (KCOT). The treatment of OOC is by enucleation and the prognosis, following enucleation is excellent with a recurrence rate of less than 2%. On the other hand, OKC has a recurrence rate between 8 and 25% after enucleation. Thus it is important to differentiate between the two entities.
Methods: All cases reported in our section as OOC during the period 2013 to 2018 were retrieved from the surgical pathology …

Incorporating Pathway Information Into Feature Selection Towards Better Performed Gene Signatures, Suyan Tian, Chi Wang, Bing Wang

Biostatistics Faculty Publications

To analyze gene expression data with sophisticated grouping structures and to extract hidden patterns from such data, feature selection is of critical importance. It is well known that genes do not function in isolation but rather work together within various metabolic, regulatory, and signaling pathways. If the biological knowledge contained within these pathways is taken into account, the resulting method is a pathway-based algorithm. Studies have demonstrated that a pathway-based method usually outperforms its gene-based counterpart in which no biological knowledge is considered. In this article, a pathway-based feature selection is firstly divided into three major categories, namely, pathway-level selection, …

Seasonal Changes In Sleep, Rpe, And Scoring Percentage In Division One Collegiate Female Basketball Players, Lindsay Perrin, Dr. Stephen Rossi

Honors College Theses

Basketball season occurs over several months and involves heavy traveling, training, competing, and scholarly duties. These demands do not allow much time for rest and recovery. A lack in the quantity and quality of sleep can reduce the ability to manage stress and reduce recovery from training and competition. This can affect the health and well-being of the athlete and their success on the court. In college, sleep schedules may change from high school by staying up later and sleeping in more. College students typically sleep between six and seven hours a night which is less than the recommended nine …

Male Determining Gene Nix May Bring An End To Transmission Of Diseases Through Mosquitoes, Mohammed Mahdi

Thinking Matters Symposium Archive

Female mosquitoes take blood from humans to gain protein needed to produce eggs, and in the process they can transmit viruses, such as Zika, Dengue, and chikungunya, or parasites, such as malaria. Male mosquitoes do not transmit diseases. This literature review will examine what is known about how sex is determined in mosquitoes and how this can be used to manipulate the females that spread diseases to humans. Using CRISPR Cas9, the lab of Zhijian Tu removed the Nix gene from mosquito embryos; all of these were feminized. Ectopic overexpression of Nix gene product in mosquito embryos caused even genetically …

Dual Therapy Treatment Of Pediatric Acute Lymphoblastic Leukemia With Blinotumomab And A Standard Chemotherapy Regimen, Tori I. Scheffler

Selected Honors Theses

Leukemia is the number one cancer affecting children in the nation, with acute lymphoblastic leukemia being the most prevalent classification.1 While new and innovative treatment protocols have greatly increased the success rate of primary cancer patients, those who face relapse receive a much more dismal prognosis. Recent studies have shown that patients who relapse quite frequently have developed drug-resistant clones of the original cancer cells, leading to a need for various secondary treatment options. The drug-resistance is due to clonal mutations that take place within the cancer cell, most often because of an outside pressure or stress within the environment …

Cadm1 Is A Twist1-Regulated Suppressor Of Invasion And Survival., Edward J. Hartsough, Michele B. Weiss, Shea A. Heilman, Timothy J. Purwin, Curtis H Kugel, Sheera R. Rosenbaum, Dan A. Erkes, Manoela Tiago, Kim Hookim, Inna Chervoneva, Andrew E. Aplin

Department of Cancer Biology Faculty Papers

Metastatic cancer remains a clinical challenge; however, patients diagnosed prior to metastatic dissemination have a good prognosis. The transcription factor, TWIST1 has been implicated in enhancing the migration and invasion steps within the metastatic cascade, but the range of TWIST1-regulated targets is poorly described. In this study, we performed expression profiling to identify the TWIST1-regulated transcriptome of melanoma cells. Gene ontology pathway analysis revealed that TWIST1 and epithelial to mesenchymal transition (EMT) were inversely correlated with levels of cell adhesion molecule 1 (CADM1). Chromatin immunoprecipitation (ChIP) studies and promoter assays demonstrated that TWIST1 physically interacts with the CADM1 promoter, suggesting …

Diffuse Low-Grade Glioma - Changing Concepts In Diagnosis And Management: A Review, Rashid Jooma, Muhammad Waqas, Inamullah Khan

Section of Neurosurgery

Though diffuse low-grade gliomas (dLGGs) represent only 15% of gliomas, they have been receiving increasing attention in the past decade. Significant advances in knowledge of the natural history and clinical diversity have been documented, and an improved pathological classification of gliomas that integrates histological features with molecular markers has been issued by the WHO. Advances in the radiological assessment of dLGG, particularly new magnetic resonance imaging scanning sequences, allow improved diagnostic and prognostic information. The management paradigms are evolving from "wait and watch" of the past to more active interventional therapy to obviate the risk of malignant transformation. New surgical …

“Oh Lord, Save Us From Such Monsters:” Maternal Impression And Monstrous Births In The Eighteenth-Century Netherlands, Sara Hollar

Independent Study Project (ISP) Collection

This historical survey focuses on the memoirs of Catharina Schrader, a Frisian midwife in the eighteenth century, as a lens into beliefs about maternal impression and monstrous births during the early modern period. The then popular theory of maternal impression, where pregnant women could impact their gestating fetus’s appearance or characteristics through their behavior, thoughts, and feelings, was used to explain many instances of monstrous births. Monstrosity, now understood as congenital defects or disabilities, was seen as a result and marker of pregnant women’s moral failings. Using examples of monstrous births from Schrader’s memoirs, I analyze the threat of maternal …

Periodontitis And The Elderly: An Overview Of The Disease And Its Impact On An Aging Population, Nicole Grace Weissenfluh

Senior Honors Theses

Periodontitis affects millions of Americans each year, and is especially prevalent among the elderly. Since periodontitis is a chronic, progressive condition, uninterrupted disease progression leads to irreversible oral damage; therefore, periodontitis often reduces the oral health-related quality of life. Furthermore, research strongly suggests a correlation between periodontitis and other systemic diseases (e.g., cardiovascular disease and diabetes mellitus), highlighting the importance of understanding, treating, and preventing periodontitis. This thesis explores the pathology and etiology of periodontitis, with special focus given to the prevalence and impact of the disease in the elderly population. Additionally, the connection between periodontitis and other systemic diseases …

The Acute Effects Of Melatonin On Striatal Dopamine Release: Progressive Electrochemical Analysis In An Ex Vivo Mouse Model Utilizing Fast Scan Cyclic Voltammetry, Kevin D. Hughes

Masters Theses

The caudate putamen is a sub region of the basal ganglia, containing neural tracts important for cognition, reward learning, and voluntary motor function. Dopamine (DA) signaling received from the dopaminergic neurons of the substantia nigra pars compacta mediate locomotion, degradation of which is the characteristic neuropathology for Parkinson’s disease (PD). PD is an initially neurovegetative motor disorder but can progress to include cognitive impairments as well. Sundowner’s syndrome (SS) has been observed in patient populations with neurodegenerative diseases, characterized by the decline of cognition into evening hours. Due to the circadian influence which the hormone melatonin has on the sleep-wake …

Risk Benefit Analysis Of Treatments For Cystic Acne, Callie Elliott

Undergraduate Honors Theses

Acne is a prevalent skin disorder and is displayed through various different incidences. Cystic acne, a severe form of acne that is difficult to treat, reaches deep into the skin underneath the epidermis layer and produces painful, inflamed cysts that contain sebum, dead skin cells, and Propionobacterium acnes, the acne causing bacteria. Because this is an uncomfortable type of acne and is tough to treat, researchers have developed and tested a number of treatments to determine the best course of treatment for reducing and potentially eradicating cystic acne. These treatments are most commonly in the form of systemic or topical …

Department of Radiation Oncology Faculty Papers

The combination of programmed cell death 1/programmed cell death ligand 1 blockade and thoracic radiotherapy has become the new standard of care in the treatment of locally advanced non-small-cell lung cancer. The information regarding the pulmonary safety of such therapy remains limited to mostly retrospective studies and case reports with a small portion of data from prospective clinical trials. By analyzing the underlying mechanisms of interactions between radiation and immunotherapy from preclinical data and summarizing safety data from relevant clinical studies with pulmonary toxicity, we believe that longer and rigorous follow-up is warranted, to determine if the combination of such …

The Pharmabiotic For Phenylketonuria: Development Of A Novel Therapeutic, Chloé Elizabeth Lebegue

Senior Theses

Phenylketonuria, now known as phenylalanine hydroxylase (PAH) deficiency, is a genetic disorder of metabolism affecting approximately one in every 15,000 infants born in the United States. Patients have nonfunctional PAH enzyme secondary to one or more genetic mutations. The enzyme deficit results in destructive supraphysiologic blood phenylalanine levels upon consumption of the essential dietary amino acid phenylalanine. Current standards of care mitigate signs and symptoms of the disorder, but do not approach a cure. The methods for creating a prototype pharmabiotic as an innovative treatment strategy for PAH deficiency are described herein.
