Sars-Cov-2 And Interferon Blockade, B. Diamond, B. T. Volpe, S. Vanpatten, Y. Al Abed

Journal Articles

© 2020, The Author(s). The response to viral infection generally includes an activation of the adaptive immune response to produce cytotoxic T cells and neutralizing antibodies. We propose that SARS-CoV-2 activates the innate immune system through the renin-angiotensin and kallikrein-bradykinin pathways, blocks interferon production and reduces an effective adaptive immune response. This model has therapeutic implications.

Differentiating Peripherally-Located Small Cell Lung Cancer From Non-Small Cell Lung Cancer Using A Ct Radiomic Approach, Bihong T. Chen, Zikuan Chen, Ningrong Ye, Isa Mambetsariev, Jeremy Fricke, Ebenezer Daniel, George Wang, Chi Wah Wong, Russell C. Rockne, Rivka R. Colen, Mohd W. Nasser, Surinder K. Batra, Andrei I.

Lung cancer can be classified into two main categories: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), which are different in treatment strategy and survival probability. The lung CT images of SCLC and NSCLC are similar such that their subtle differences are hardly visually discernible by the human eye through conventional imaging evaluation. We hypothesize that SCLC/NSCLC differentiation could be achieved via computerized image feature analysis and classification in feature space, as termed a radiomic model. The purpose of this study was to use CT radiomics to differentiate SCLC from NSCLC adenocarcinoma. Patients with primary lung cancer, …

OBJECTIVES: Oncology has become more reliant on new testing methods and a greater use of electronic medical records, which provide a plethora of information available to physicians and researchers. However, to take advantage of vital clinical and research data for precision medicine, we must initially make an effort to create an infrastructure for the collection, storage, and utilization of this information with uniquely designed disease-specific registries that could support the collection of a large number of patients.

MATERIALS AND METHODS: In this study, we perform an in-depth analysis of a series of lung adenocarcinoma patients (n = 415) with genomic …

Micrornas Orchestrate Pathophysiology Of Breast Cancer Brain Metastasis: Advances In Therapy, Ranjana K. Kanchan, Jawed A. Siddiqui, Sidharth Mahapatra, Surinder K. Batra, Mohd W. Nasser

Journal Articles: Biochemistry & Molecular Biology

Brain metastasis (BM) predominantly occurs in triple-negative (TN) and epidermal growth factor 2 (HER2)-positive breast cancer (BC) patients, and currently, there is an unmet need for the treatment of these patients. BM is a complex process that is regulated by the formation of a metastatic niche. A better understanding of the brain metastatic processes and the crosstalk between cancer cells and brain microenvironment is essential for designing a novel therapeutic approach. In this context, the aberrant expression of miRNA has been shown to be associated with BM. These non-coding RNAs/miRNAs regulate metastasis through modulating the formation of a metastatic niche …

Mechanistic And Functional Shades Of Mucins And Associated Glycans In Colon Cancer, Ramesh Pothuraju, Shiv Ram Krishn, Shailendra K. Gautam, Priya Pai, Koelina Ganguly, Sanjib Chaudhary, Satyanarayana Rachagani, Sukhwinder Kaur, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

Mucus serves as the chief protective barrier against pathogenic and mechanical insults in respiratory, gastrointestinal, and urogenital tracts. Altered mucin expression, the major component of mucus, in conjunction with differential glycosylation has been strongly associated with both benign and malignant pathologies of colon. Mucins and their associated glycans arbitrate their impact sterically as well as mechanically by altering molecular and microbial spectrum during pathogenesis. Mucin expression in normal and pathological conditions is regulated by nonspecific (dietary factors and gut microbiota) and specific (epigenetic and transcriptional) modulators. Further, recent studies highlight the impact of altering mucin glycome (cancer-associated carbohydrate antigens including …

Molecular Implications Of Muc5ac-Cd44 Axis In Colorectal Cancer Progression And Chemoresistance, Ramesh Pothuraju, Satyanarayana Rachagani, Shiv Ram Krishn, Sanjib Chaudhary, Rama Krishna Nimmakayala, Jawed A. Siddiqui, Koelina Ganguly, Imayavaramban Lakshmanan, Jesse L. Cox, Kavita Mallya, Sukhwinder Kaur, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

BACKGROUND: Differential expression of mucins has been associated with several cancers including colorectal cancer (CRC). In normal physiological conditions, secretory mucin MUC5AC is not expressed in the colonic mucosa, whereas its aberrant expression is observed during development of colon cancer and its precursor lesions. To date, the molecular mechanism of MUC5AC in CRC progression and drug resistance remains obscure.

METHODS: MUC5AC expression was determined in colon tissue microarray by immunohistochemistry. A RNA interference and CRISPR/Cas9-mediated system was used to knockdown/knockout the MUC5AC in CRC cell lines to delineate its role in CRC tumorigenesis using in vitro functional assays and in …

Glp-1 Mediated Diuresis And Natriuresis Are Blunted In Heart Failure And Restored By Selective Afferent Renal Denervation, Kenichi Katsurada, Shyam Sundar Nandi, Hong Zheng, Xuefei Liu, Neeru M. Sharma, Kaushik K. Patel

Journal Articles: Cellular & Integrative Physiology

BACKGROUND: Glucagon-like peptide-1 (GLP-1) induces diuresis and natriuresis. Previously we have shown that GLP-1 activates afferent renal nerve to increase efferent renal sympathetic nerve activity that negates the diuresis and natriuresis as a negative feedback mechanism in normal rats. However, renal effects of GLP-1 in heart failure (HF) has not been elucidated. The present study was designed to assess GLP-1-induced diuresis and natriuresis in rats with HF and its interactions with renal nerve activity.

METHODS: HF was induced in rats by coronary artery ligation. The direct recording of afferent renal nerve activity (ARNA) with intrapelvic injection of GLP-1 and total …

Articles

Whereas the diagnosis of moderate and severe traumatic brain injury (TBI) is readily visible on current medical imaging paradigms (magnetic resonance imaging [MRI] and computed tomography [CT] scanning), a far greater challenge is associated with the diagnosis and subsequent management of mild TBI (mTBI), especially concussion which, by definition, is characterized by a normal CT. To investigate whether the integrity of the blood-brain barrier (BBB) is altered in a high-risk population for concussions, we studied professional mixed martial arts (MMA) fighters and adolescent rugby players. Additionally, we performed the linear regression between the BBB disruption defined by increased gadolinium contrast …

Ectopic Pregnancy In A Woman With T9 Ais A Paraplegia Secondary To High-Grade Spinal Cord Pilocytic Astrocytoma, Elisabeth K. Acker

Graduate Medical Education (GME) Resident and Fellow Research Day Posters

Ectopic pregnancy in a woman with T9 AIS A (motor complete, sensory complete) paraplegia secondary to a high-grade spinal cord pilocytic astrocytoma

Background

In the United States, 20,000 women of childbearing age have a spinal cord injury (SCI). While SCI induces transient amenorrhea immediately after injury, women generally have normal reproductive function after SCI, and their fertility is unimpaired. Medications that commonly manage complications of SCI should be avoided or discontinued during pregnancy. Complications inherent to SCI, including urologic issues, are often exacerbated during pregnancy.

Methods

This is a case report on a female Veteran who initially presented to the …

Prevalence Of The Hypervirulent Nap1/Bi/027 Strain Of C. Difficile In Southwestern Virginia And Risk Factors Associated With Infection, Andrew O. Hanna, Anthony Baffoe-Bonnie, Shikha Vasudeva

Graduate Medical Education (GME) Resident and Fellow Research Day Posters

C. difficile infection (CDI) incidence has increased over the last several decades. The BI/NAP1/027 ribotype was discovered in 2005 and has since been responsible for multiple outbreaks in the US and Canada. This subtype of C. Difficile is known to be more virulent in vivo and produce more severe disease. Limited regional data of the prevalence of this ribotype is available, which could help guide treatment. Using infection control data from a large regional hospital and a VA medical center, this study documented the prevalence of the 027 ribotype in Southwest Virginia. Patients were included if they were tested at …

Untangling The Dorsal Diencephalic Conduction System: A Review Of Structure And Function Of The Stria Medullaris, Habenula And Fasciculus Retroflexus, Elena Roman, Joshua Weininger, Basil Lim, Marin Roman, Denis Barry, Paul Tierney, Erik O'Hanlon, Kirk Levins, Veronica O'Keane, Darren Roddy

Other

The often-overlooked dorsal diencephalic conduction system (DDCS) is a highly conserved pathway linking the basal forebrain and the monoaminergic brainstem. It consists of three key structures; the stria medullaris, the habenula and the fasciculus retrofexus. The frst component of the DDCS, the stria medullaris, is a discrete bilateral tract composed of fbers from the basal forebrain that terminate in the triangular eminence of the stalk of the pineal gland, known as the habenula. The habenula acts as a relay hub where incoming signals from the stria medullaris are processed and subsequently relayed to the midbrain and hindbrain monoaminergic nuclei through …

Role Of Atp1a1 In Skeletal Muscle Growth And Metabolism, Laura C. Kutz

Theses, Dissertations and Capstones

Skeletal muscle comprises approximately 30% of total body mass, and loss of muscle mass and dysfunctional muscle metabolism are implicated in multiple disease states, including type 2 diabetes, heart failure, and septic shock. As such, understanding the mechanisms of skeletal muscle growth and atrophy, including pharmaceutical targets that may prove safe and effective, is therefore an important goal of current research on skeletal muscle physiology. One potential target in skeletal muscle development and function that has not been fully explored is the Na/KATPase (NKA), especially the α1 isoform. This isoform has a unique signaling function that has previously been shown …

Dysfunctional Mitochondrial Biogenesis: A Potential Underlying Cause For Metabolic Diseases, Caroline Ann Hunter

Theses, Dissertations and Capstones

Mitochondria are essential organelles that play crucial roles in many aspects of cellular homeostasis. More importantly, the mitochondria are home to the majority of the metabolic pathways within the cell and are responsible for producing most of the cell’s useable energy in the form of adenine triphosphate (ATP) through oxidative phosphorylation (OXPHOS). In mammals, the majority of OXPHOS complex subunits are encoded by nuclear deoxyribonucleic acid (DNA); however, 13 core subunits essential for the function of OXPHOS complexes I, III, IV, and V are encoded in the mitochondrial (mt) DNA (mtDNA) and are synthesized within the mitochondria by its own …

Impact Of Geographic Location And Social Determinants Of Health On Lung Cancer Incidence And Mortality Rates, Katherine Ashley

Mahurin Honors College Capstone Experience/Thesis Projects

This paper studies the effect of geographic location and socioeconomic status, specifically level of education and income, on rates of incidence and mortality of lung and bronchus cancer. While some prior studies have focused on socioeconomic status’ and global geographic location’s impact on these rates, few have focused on the impact in Appalachian Kentucky and non-Appalachian Kentucky. In this paper, level of education and income are controlled for using four variables: median household income, percentage of persons in poverty, percentage of high school graduates or higher who are at least 25, and percentage of persons with a bachelor’s degree or …

The Coulter Principle: For The Good Of Humankind, Marshall Graham

Theses and Dissertations--History

The atomic bombings of Hiroshima and Nagasaki in August 1945 made Wallace H. Coulter abruptly comprehend the critical need for rapid and accurate blood-cell counts in providing care for victims of radiation exposure. This thesis documents the unwritten story of his journey from that comprehension through his invention and implementation of the Coulter Principle, its commercialization in the first widely available automated blood-cell counter, and elaboration of that ground-breaking counter into increasingly sophisticated instrumentation for analysis not only of blood cells, but of particles involved in many other scientific disciplines. International cold-war politics and the burgeoning of increasingly powerful nuclear …

Examining The Role Of Metabolic Pathways As Therapeutic Modalities For Triple Negative Breast Cancer, Jeremy Andrew Johnson

Theses and Dissertations--Toxicology and Cancer Biology

Triple negative breast cancer (TNBC) comprises 15-20% of breast cancers, affects a younger patient population than other subtypes, and is very aggressive. TNBC is comprised of a diverse group of tumors that have proven refractory to targeted therapy and can be difficult to treat. Patients generally receive neoadjuvant chemotherapy (NAC), surgery, and radiotherapy. The standard of care for NAC includes a taxane, an anthracycline, and/or cyclophosphamide, and administration of NAC has resulted in pathological complete response (pCR) in 30-40% of patients. However, a majority of TNBC patients will not reach pCR and instead have residual disease (RD), which is associated …

The Self-Perceived Impact Of A Food Recovery-Meal Delivery Program On Homebound Seniors’ Food Security, Nutrition Health, And Well-Being, Alice Marie Sanchez

UNF Graduate Theses and Dissertations

For many senior citizens, meeting nutritional needs is essential to good health and daily function. Studies indicate that many American older adults are not meeting their nutrition needs and often suffer from food insecurity. Meals on Wings (MOW) is a food recovery-meal delivery program that attempts to decrease the influence of food insecurity among older adults. This study aims to explore the self-perceived impact of a food recovery-meal delivery program on homebound seniors’ nutrition health, food security, and well-being.

Semi-structured interviews were administered to adults age 55 and older on the waitlist for Meals on Wheels America in Duval County …
