Exploring The Regulatory Mechanism Of The Notch Ligand Receptor Jagged1 Via The Aryl Hydrocarbon Receptor In Breast Cancer, Sean Alan Piwarski Jan 2018

Exploring The Regulatory Mechanism Of The Notch Ligand Receptor Jagged1 Via The Aryl Hydrocarbon Receptor In Breast Cancer, Sean Alan Piwarski

Theses, Dissertations and Capstones

The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that binds pollutants, therapeutic drugs and endogenous ligands. AHR is of particular interest in cancer and has been shown to play roles in both tumor progression and tumor suppression. As a result, it has received growing attention as a possible chemotherapeutic target. AHR is expressed in all breast cancer subtypes and can promote or inhibit breast cancer depending on the ligand it binds. The Notch signaling pathway is a highly conserved evolutionary pathway that plays extremely vital roles during development by regulating cell fate and differentiation. Notch signaling has increasingly …


Use Of Memantine In Autism Spectrum Disorder: A Case Report, Adam Schindzielorz Md, Kristina Bryant-Melvin Md, Suzanne Holroyd Md, Kelly Melvin Md Jan 2018

Use Of Memantine In Autism Spectrum Disorder: A Case Report, Adam Schindzielorz Md, Kristina Bryant-Melvin Md, Suzanne Holroyd Md, Kelly Melvin Md

Psychiatry

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder of varying severity and phenotypic expression that is characterized by persistent deficits in social relatedness, communication skills, and interfering repetitive behaviors. Associated behavioral pathology can include inattention, aggression, irritability, hyperactivity, anxiety, and self-injury. Currently, FDAapproved treatments exist to treat secondary symptoms but not core symptomatology. The etiology of autism and other ASD is thought to be multifactorial but is not well understood. Some studies suggest that glutamate excitotoxicity may play a role in the pathogenesis of ASD. Memantine, an NMDAreceptor antagonist, could potentially address core symptoms in ASD by targeting disease-specific pathophysiology. …

Theses, Dissertations and Capstones

Metabolic syndrome is one of the fastest growing health problems in the world. The medical costs associated with treating this disorder are staggering. Allowed to proceed untreated, metabolic syndrome can lead to a markedly decreased quality of life and a variety of medical conditions including heart and kidney failure. Whether the sodium glucose co-transporter-2 (SGLT-2) inhibitor Empagliflozin can be used to prevent the development of metabolic syndrome is not well understood. This proposal is specifically designed to address this gap in our knowledge. The expected outcomes of this work will identify the time course and degree of interrelatedness between changes …


A Coal Miner With Weakness, Fatigue, Nausea, Fever, Chills, Night Sweats And Dyspnea, Larry Nichols Oct 2017

A Coal Miner With Weakness, Fatigue, Nausea, Fever, Chills, Night Sweats And Dyspnea, Larry Nichols

Marshall Journal of Medicine

Delayed or missed diagnoses are a constant hazard in primary care. This is the case report of a 51-year-old coal miner, who presented as an ambulatory outpatient on a Friday with weakness, fatigue, nausea, fever, chills, night sweats and dyspnea. Chest x-ray on Saturday showed pneumonia and pleural effusion, while blood testing showed renal failure, but these results were not known by his physician until Monday, when he was hospitalized with severe sepsis due to fatal Austrian syndrome of pneumococcal pneumonia, endocarditis and meningitis. Analysis of the delay of diagnosis in this case suggests the possibility that a weekend effect …

Optimizing Heart Failure Outcomes Through Diet: A Review, Farley B. Neasman Iii Jul 2017

Optimizing Heart Failure Outcomes Through Diet: A Review, Farley B. Neasman Iii

Marshall Journal of Medicine

Heart failure is a growing epidemic that will add significant monetary and human costs to an already overtaxed health-care system. Though promising new medications have recently been approved, this complex condition is largely preventable through aggressive risk factor modification, with diet being shown to have a greater effect than exercise. An underrated component of a healthy diet is the simple addition of nuts – the anti-inflammatory fatty acids, healthy proteins, and general availability have been shown to improve survival and reduce the primary risk factors contributing to heart failure, making the addition of nuts and legumes to the diet an …

Signalling Via The Osteopontin And High Mobility Group Box-1 Axis Drives The Fibrogenic Response To Liver Injury, Elena Arriazu, Xiaodong Ge, Tung-Ming Leung, Fernando Magdaleno, Aritz Lopategi, Yongke Lu, Naoto Kitamura, Raquel Urtasun, Neil Theise, Daniel J. Antoine, Natalia Nieto

Pharmacology, Physiology and Toxicology

Objective: Liver fibrosis is associated with significant collagen-I deposition largely produced by activated hepatic stellate cells (HSCs); yet, the link between hepatocyte damage and the HSC profibrogenic response remains unclear. Here we show significant induction of osteopontin (OPN) and high-mobility group box-1 (HMGB1) in liver fibrosis. Since OPN was identified as upstream of HMGB1, we hypothesised that OPN could participate in the pathogenesis of liver fibrosis by increasing HMGB1 to upregulate collagen-I expression. Design and results: Patients with long-term hepatitis C virus (HCV) progressing in disease stage displayed enhanced hepatic OPN and HMGB1 immunostaining, which correlated with fibrosis stage, whereas …

Primerano, Joseph Horzempa

Biochemistry and Microbiology

Francisella tularensis is an extremely virulent bacterium that can be transmitted naturally by blood sucking arthropods. During mammalian infection, F. tularensis infects numerous types of host cells, including erythrocytes. As erythrocytes do not undergo phagocytosis or endocytosis, it remains unknown how F. tularensisinvades these cells. Furthermore, the consequence of inhabiting the intracellular space of red blood cells (RBCs) has not been determined. Here, we provide evidence indicating that residing within an erythrocyte enhances the ability of F. tularensis to colonize ticks following a blood meal. Erythrocyte residence protected F. tularensis from a low pH environment similar to that of …


An Unusual Pulmonary Complication Of Statin Medication, Milliejoan Mongalo, Madhvi Shah, Lynne J. Goebel Apr 2017

An Unusual Pulmonary Complication Of Statin Medication, Milliejoan Mongalo, Madhvi Shah, Lynne J. Goebel

Marshall Journal of Medicine

Statins or hydroxyl-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors have proven efficacy at decreasing cardiovascular morbidity and mortality. Although statins have been prescribed safely, there should be more awareness of the possible adverse effects. Recently, we encountered a patient who had unexplained dyspnea, weakness, and immobility. The patient’s symptoms were alleviated after discontinuing the statin medication. Although we have no concrete evidence that her symptoms were due to the medication, the temporal relationship of symptom improvement upon discontinuation of the statin, led us to the conclusion that it could potentially have been the cause. Unexplained dyspnea is not listed as an …

Cigarette Smoking And Cardio-Renal Events In Patients With Atherosclerotic Renal Artery Stenosis, Christopher A. Drummond, Pamela S. Brewster, Wencan He, Kaili Ren, Yanmei Xie, Katherine R. Tuttle, Steven T. Haller, Kenneth Jamerson, Lance D. Dworkin, Donald E. Cutlip, Timothy P. Murphy, Ralph B. D'Agostino Sr., William L. Henrich, Jiang Tian, Joseph I. Shapiro Md, Christopher J. Cooper

Biochemistry and Microbiology

Cigarette smoking causes cardiovascular disease and is associated with poor kidney function in individuals with diabetes mellitus and primary kidney diseases. However, the association of smoking on patients with atherosclerotic renal artery stenosis has not been studied. The current study utilized data from the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL, NCT00081731) clinical trial to evaluate the effects of smoking on the risk of cardio-renal events and kidney function in this population. Baseline data showed that smokers (n = 277 out of 931) were significantly younger at enrollment than non-smokers (63.3±9.1 years vs 72.4±7.8 years; p<0.001). In addition, patients who smoke were also more likely to have bilateral renal artery stenoses and peripheral vascular disease (PVD). Longitudinal analysis showed that smokers experienced composite endpoint events (defined as first occurrence of: stroke; cardiovascular or renal death; myocardial infarction; hospitalization for congestive heart failure; permanent renal replacement; and progressive renal insufficiency defined as 30% reduction of GFR from baseline sustained for ≥ 60 days) at a substantially younger age compared to non-smokers (67.1±9.0 versus 76.1±7.9, p<0.001). Using linear regression and generalized linear modeling analysis controlled by age, sex, and ethnicity, smokers had significantly higher cystatin C levels (1.3±0.7 vs 1.2±0.9, p<0.01) whereas creatinine and estimated glomerular filtration rate (eGFR) were not different from non-smokers. From these data we conclude that smoking has a significant association with deleterious cardio-renal outcomes in patients with renovascular hypertension.


Na/K-Atpase Signaling And Salt Sensitivity: The Role Of Oxidative Stress, Jiang Liu, Yanling Yan, Ying Nie Mar 2017

Na/K-Atpase Signaling And Salt Sensitivity: The Role Of Oxidative Stress, Jiang Liu, Yanling Yan, Ying Nie

Biochemistry and Microbiology

Other than genetic regulation of salt sensitivity of blood pressure, many factors have been shown to regulate renal sodium handling which contributes to long-term blood pressure regulation and have been extensively reviewed. Here we present our progress on the Na/K-ATPase signaling mediated sodium reabsorption in renal proximal tubules, from cardiotonic steroids-mediated to reactive oxygen species (ROS)-mediated Na/K-ATPase signaling that contributes to experimental salt sensitivity.

Comparative Study On The In Vitro Effects Of Pseudomonas Aeruginosa And Seaweed Alginates On Human Gut Microbiota, Shaofeng Bai, Huahai Chen, Liying Zhu, Wei Liu, Hongwei Yu, Xin Wang, Yeshi Yin

Biochemistry and Microbiology

Alginates pertain to organic polysaccharides that have been extensively used in food- and medicine-related industries. The present study obtained alginates from an alginate overproducing Pseudomonas aeruginosa PAO1 mutant by screening transposon mutagenesis libraries. The interaction between bacterial and seaweed alginates and gut microbiota were further studied by using an in vitro batch fermentation system. Thin-layer chromatography (TLC) analysis indicated that both bacterial and seaweed alginates can be completely degraded by fecal bacteria isolated from study volunteers, indicating that a minor structural difference between bacterial and seaweed alginates (O-acetylation and lack of G-G blocks) didn’t affect the digestion of alginates by …

Ultrasound imaging can be used to determine the width of the medial joint space. This study will determine whether altering the joint angle in the elbow during various clinical tests has an effect on the width of the medial joint space.

Methods: Ultrasound images of the non-dominant elbow were collected during three clinical tests of medial elbow stability; valgus stress test, weighted valgus test and the milking maneuver. The …


Local Sensitivity Analysis Of Acute Inflammation, James Martin Jan 2017

Local Sensitivity Analysis Of Acute Inflammation, James Martin

Theses, Dissertations and Capstones

The inflammatory response is the body's response to some pathogen or foreign invader. When infected by a pathogen, a healthy individual will mount a response with immunological factors to eliminate it. An inflammatory response that is either too strong or too weak can be detrimental to the individual's health. We will look at a qualitative mathematical model of the inflammatory response, in scenarios that represent varying disorders of the immune system. Using sensitivity analysis we determine which parameters of this model are most influential in the different scenarios. By determining which parameters are most influential we can suggest possible targets …


Doxorubicin Cytotoxicity In A Human Proximal Tubular Epithelial Cell Line Was Attenuated By The Natural Product Resveratrol, Morghan Schuyler Getty Jan 2017

Doxorubicin Cytotoxicity In A Human Proximal Tubular Epithelial Cell Line Was Attenuated By The Natural Product Resveratrol, Morghan Schuyler Getty

Theses, Dissertations and Capstones

The cancer chemotherapeutic agent doxorubicin (DOX), Adriamycin, is part of the treatment regimen for breast, ovarian, small cell lung cancer and acute/chronic lymphoid leukemia. Adverse effects associated with DOX are cardiotoxicity and nephrotoxicity. Interventions are needed to reduce DOX nephrotoxicity. Resveratrol (RES) is a phytochemical contained in grapes, berries and nuts, which possesses antioxidant and anticancer properties. This study tested the hypothesis that RES will attenuate DOX renal cytotoxicity in human noncancerous renal proximal tubular epithelial (HK-2) cells and that RES will reduce DOX mediated changes in mitochondrial function. HK-2 cells were plated and grown for 48 hours (h). Cells …


Employing The Enzyme Cofactor Function Of Ascorbic Acid To Affect Oncogenic Pathways In Human Melanoma: Modulating Hypoxia Inducible Factor-1Α And Dna Demethylation To Reduce Malignant Potential, Adam Patrick Fischer Jan 2017

Employing The Enzyme Cofactor Function Of Ascorbic Acid To Affect Oncogenic Pathways In Human Melanoma: Modulating Hypoxia Inducible Factor-1Α And Dna Demethylation To Reduce Malignant Potential, Adam Patrick Fischer

Theses, Dissertations and Capstones

Dioxygenase enzymes such as the HIF hydroxylases (PHD1-3, FIH) and the Ten-eleven translocation (TET1-3) enzymes regulate the activity of the hypoxia inducible factor-1a (HIF1a) transcription factor and the DNA methylation status of cells, respectively. Aberrant accumulation and activation of HIF-1a can allow malignant cells to acquire attributes that promote progression, chemotherapy resistance, and survival, while aberrant hypermethylation of gene promoters can silence the expression of tumor suppressor genes essential to preventing tumorigenesis. Inadequate levels of intracellular ascorbic acid (AA), a necessary cofactor for optimal dioxygenase enzyme function, could potentiate these tumorigenic conditions. In fact, plasma levels …

Baylisascaris Procyonis Exposure Case Study, Andrea M. Lauffer M.D., Patricia Lutz M.D., Susan L. Flesher M.D.

Pediatrics

We report a case of exposure to raccoon feces found to be contaminated with baylisascaris procyonis. The exposure was recognized early enough by the family to allow prophylaxis with albendazole. Because of the potential fatal or neurologically catastrophic effects of this disease immediate treatment is indicated. This is started in advance of environmental studies that are done to determine if the feces is indeed contaminated.


Multipoint Genome-Wide Linkage Scan For Nonword Repetition In A Multigenerational Family Further Supports Chromosome 13q As A Locus For Verbal Trait Disorders, D. T. Truong, L. D. Shriberg, S. D.

Biochemistry and Microbiology

Verbal trait disorders encompass a wide range of conditions and are marked by deficits in five domains that impair a person’s ability to communicate: speech, language, reading, spelling, and writing. Nonword repetition is a robust endophenotype for verbal trait disorders that is sensitive to cognitive processes critical to verbal development, including auditory processing, phonological working memory, and motor planning and programming. In the present study, we present a six-generation extended pedigree with a history of verbal trait disorders. Using genome-wide multipoint variance component linkage analysis of nonword repetition, we identified a region spanning chromosome 13q14–q21 with LOD = 4.45 between …


Epoxyeicosatrienoic Acids Regulate Adipocyte Differentiation Of Mouse 3t3 Cells, Via Pgc-1Α Activation, Which Is Required For Ho-1 Expression And Increased Mitochondrial Function, Maayan Waldman, Lars Bellner, Luca Vanella, Joseph Schragenheim, Komal Sodhi, Shailendra P.

Singh, Daohong Lin, Anand Lakhkar, Jiangwei Li, Edith Hochhauser, Michael Arad, Zbigniew Darzynkiewicz, Attallah Kappas, Nader G. Abraham

Biochemistry and Microbiology

Epoxyeicosatrienoic acid (EET) contributes to browning of white adipose stem cells to ameliorate obesity/diabetes and insulin resistance. In the current study, we show that EET altered preadipocyte function, enhanced peroxisome proliferation-activated receptor γ coactivator α (PGC-1α) expression, and increased mitochondrial function in the 3T3-L1 preadipocyte subjected to adipogenesis. Cells treated with EET resulted in an increase, P < 0.05, in PGC-1α and a decrease in mitochondria-derived ROS (MitoSox), P < 0.05. The EET increase in heme oxygenase-1 (HO-1) levels is dependent on activation of PGC-1α as cells deficient in PGC-1α (PGC-1α knockout adipocyte cell) have an impaired ability to express HO-1, P < 0.02. Additionally, adipocytes treated with EET exhibited an increase in mitochondrial superoxide dismutase (SOD) in a PGC-1α-dependent manner, P < 0.05. The increase in PGC-1α was associated with an increase in β-catenin, P < 0.05, adiponectin expression, P < 0.05, and lipid accumulation, P < 0.02. EET decreased heme levels and mitochondria-derived ROS (MitoSox), P < 0.05, compared to adipocytes that were untreated. EET also decreased mesoderm-specific transcript (MEST) mRNA and protein levels (P < 0.05). Adipocyte secretion of EET act in an autocrine/paracrine manner to increase PGC-1α is required for activation of HO-1 expression. This is the first study to dissect the mechanism by which the antiadipogenic and anti-inflammatory lipid, EET, induces the PGC-1α signaling cascade and reprograms the adipocyte phenotype by regulating mitochondrial function and HO-1 expression, leading to an increase in healthy, that is, small, adipocytes and a decrease in adipocyte enlargement and terminal differentiation. This is manifested by an increase in mitochondrial function and an increase in the canonical Wnt signaling cascade during adipocyte proliferation and terminal differentiation.

Spinal Cord Injury And Autonomic Dysreflexia- A Case Report, Apurva Bhatt, Brit Moore, Talal Asif, Kristy E. Steigerwalt, Rebecca R. Pauly

Marshall Journal of Medicine

Autonomic dysreflexia (AD) is a life threatening condition affecting patients with spinal cord lesions T6 level and above. A 51 year old male with a history of paraplegia due to a C6 spinal cord injury (30 years prior) presented with recurrent debilitating episodic diaphoresis, hypertension, low body temperature, and bradycardia. Previous hospitalizations presumed sepsis from UTI to be the etiology, however on further evaluation his symptoms were consistent with undiagnosed AD. This article describes a unique case presentation and reviews AD in depth, including the etiology, pathophysiology and management.

Abraham, Zijian Xie, Joseph I. Shapiro Md

Biochemistry and Microbiology

We have previously reported that the sodium potassium adenosine triphosphatase (Na/K-ATPase) can effect the amplification of reactive oxygen species. In this study, we examined whether attenuation of oxidant stress by antagonism of Na/K-ATPase oxidant amplification might ameliorate experimental uremic cardiomyopathy induced by partial nephrectomy (PNx). PNx induced the development of cardiac morphological and biochemical changes consistent with human uremic cardiomyopathy. Both inhibition of Na/K-ATPase oxidant amplification with pNaKtide and induction of heme oxygenase-1 (HO-1) with cobalt protoporphyrin (CoPP) markedly attenuated the development of phenotypical features of uremic cardiomyopathy. In a reversal study, administration of pNaKtide after the induction of uremic …

Shapiro, Brahma R. Mopidevi, Muhammad Chaudhry, Kyle Maxwell, Steven T. Haller, Christopher A. Drummond, David J. Keendey, Jiang Tian, Deepak Malhorta, Zijian Xie, Joseph I. Shapiro Md, Jiang Liu

Biochemistry and Microbiology

Background We have demonstrated that cardiotonic steroids, such as ouabain, signaling through the Na/K‐ATPase, regulate sodium reabsorption in the renal proximal tubule. By direct carbonylation modification of the Pro222 residue in the actuator (A) domain of pig Na/K‐ATPase α1 subunit, reactive oxygen species are required for ouabain‐stimulated Na/K‐ATPase/c‐Src signaling and subsequent regulation of active transepithelial 22Na+ transport. In the present study we sought to determine the functional role of Pro222 carbonylation in Na/K‐ATPase signaling and sodium handling.

Methods and Results Stable pig α1 knockdown LLC‐PK1‐originated PY‐17 cells were rescued by expressing wild‐type rat α1 and rat α1 with …


The Role Of Na/K-Atpase Signaling In Oxidative Stress Related To Obesity And Cardiovascular Disease, Krithika Srikanthan, Joseph I. Shapiro Md, Komal Sodhi Sep 2016

The Role Of Na/K-Atpase Signaling In Oxidative Stress Related To Obesity And Cardiovascular Disease, Krithika Srikanthan, Joseph I. Shapiro Md, Komal Sodhi

Biochemistry and Microbiology

Na/K-ATPase has been extensively studied for its ion pumping function, but, in the past several decades, has been identified as a scaffolding and signaling protein. Initially it was found that cardiotonic steroids (CTS) mediate signal transduction through the Na/K-ATPase and result in the generation of reactive oxygen species (ROS), which are also capable of initiating the signal cascade. However, in recent years, this Na/K-ATPase/ROS amplification loop has demonstrated significance in oxidative stress related disease states, including obesity, atherosclerosis, heart failure, uremic cardiomyopathy, and hypertension. The discovery of this novel oxidative stress signaling pathway, holds significant therapeutic

Abstract

Title: Incidence of hypomagnesemia on proton pump inhibitors at the Huntington Veterans Affairs Medical Center – IHOP

Purpose:

Proton pump inhibitors (PPIs), both prescription and over-the-counter, are widely used for the treatment of acid-related disease states such as dyspepsia, gastroesophageal reflex disease, esophagitis, and peptic ulcers. These medications are generally considered safe in most patient populations; however, there are several adverse effects that may occur with long-term use. Hypomagnesemia is a newer complication arising in the literature following multiple case reports over the past several years, although the true incidence of hypomagnesemia associated with PPI use remains unclear at …
