The Promise Of Systems Biology Approaches For Revealing Host Pathogen Interactions In Malaria., Meghan Zuck, Laura S Austin, Samuel A Danziger, John D Aitchison, Alexis Kaushansky

Articles, Abstracts, and Reports

Despite global eradication efforts over the past century, malaria remains a devastating public health burden, causing almost half a million deaths annually (WHO, 2016). A detailed understanding of the mechanisms that control malaria infection has been hindered by technical challenges of studying a complex parasite life cycle in multiple hosts. While many interventions targeting the parasite have been implemented, the complex biology of

Tryptophan 375 Stabilizes The Outer-Domain Core Of Gp120 For Hiv Vaccine Immunogen Design, Duoyi Hu, Dane Bowder, Wenzhong Wei, Jesse Thompson, Mark A. Wilson, Shi-Hua Xiang

Nebraska Center for Virology: Faculty Publications

The outer-domain core of gp120 may serve as a better HIV vaccine immunogen than the full-length gp120 because of its greater stability and immunogenicity. In our previous report, we introduced two disulfide bonds to the outer-domain core of gp120 to fix its conformation into a CD4-bound state, which resulted in a significant increase in its immunogenicity when compared to the wild-type outer-domain core. In this report, to further improve the immunogenicity of the outer-domain core based immunogen, we have introduced a Tryptophan residue at gp120 amino acid sequence position 375 (375S/W). Our data from immunized guinea pigs indeed shows a …

Assessment Of Coronary Artery Outward Remodeling In Consequence Of Excision Of Epicardial Adipose Tissue In Ossabaw Swine, Kelly Coderre

Undergraduate Honors Thesis Collection

Background

Coronary artery disease (CAD) results from the buildup of cholesterol, inflammatory factors, and proliferating smooth muscle cells within a vessel wall. This plaque impedes on the vessel lumen, decreasing the space through which blood can flow, leading to an array of complications in the human body. To offset these effects, the arterial wall undergoes outward remodeling, a compensatory physiologic phenomenon that blood vessels undertake when burdened with a blockage, such as CAD. In a previously conducted study, a coronary epicardial adipose tissue excision (cEATx) surgery was performed above the left anterior descending (LAD) in Ossabaw swine to investigate the …

First 100 Cases Of Bls First Responder A Dministered Naloxone In A Statewide Ems System, Joshua Mastenbrook, James Markman, Tyler Koedam, William Fales

Research Day

Abstract Title: FIRST 100 CASES OF BLS FIRST RESPONDER ADMINISTERED NALOXONE IN A STATEWIDE EMS SYSTEM Abstract ID: 240 Abstract Category: Clinical Research BACKGROUND: In October 2015, a midwestern state law mandated that all BLS first responder (FR) agencies be trained and equipped to administer naloxone to suspected opioid-overdose patients. Although well intentioned, several questions have arisen: does naloxone use displace emphasis on early positive pressure ventilation (PPV), is naloxone being appropriately administered, and does the mandate affect patient outcome. The purpose of this study is to evaluate the first 100 cases of FR administered naloxone (FR-naloxone) for administration appropriateness …

Childhood Idiopathic Pulmonary Hypertension: A Case Report, Nathaniel Balmert, Joseph Prahlow

Introduction: Pulmonary arterial hypertension (PAH) is characterized as average pulmonary artery pressure of greater than 25mm Hg at rest. Childhood idiopathic pulmonary hypertensions (CIPH) is distinguishable from PAH by the absence of family history or underlying disease. Symptoms of CIPH include dyspnea, exercise limitation, and syncope. Common organ-specific changes include right ventricular hypertrophy and right ventricular strain. We present the case of a 6-year-old girl presenting with idiopathic pulmonary arterial hypertension aggravated by esophageal intubation. Methods: This case is from the files of one of the authors, a forensic pathologist. Case Report and Discussion: Diagnosed with pulmonary arterial hypertension when …

Infection-Associated Mycobacterium Fortuitum Infection, Dennis T. Huang, Larry Lutwick

Research Day

Introduction: Mycobacterial species are unusual causes of skin and soft tissue infections and can be difficult to diagnose in the absence of consideration as they often require specific culture media and longer incubation times. We report a Mycobacterium fortuitum subcutaneous abscess in a diabetic related to medication injection that was initially diagnosed without specialized media or prolonged incubation times. Case Report: A 48 year old diabetic female developed a progressive subcutaneous swelling in the tissues of the right lower abdominal wall where she had been injecting liraglutide. Because of continued enlargement "to almost egg size" with pain, she was empirically …

Pathology, East Africa

Hospital-acquired infections (HAIs) are a major concern to healthcare systems around the world. They are associated with significant morbidity and mortality, in addition to increased hospitalization costs. Recent outbreaks, including those caused by the Middle East respiratory syndrome coronavirus and Ebola virus, have highlighted the importance of infection control. Moreover, HAIs, especially those caused by multidrug-resistant Gram-negative rods, have become a top global priority. Although adequate approaches and guidelines have been in existence for many years and have often proven effective in some countries, the implementation of such approaches in low- and middle-income countries (LMICs) is often restricted due to …

Electrosensitization Increases Antitumor Effectiveness Of Nanosecond Pulsed Electric Fields In Vivo, Claudia Muratori, Andrei G. Pakhomov, Loree Heller, Maura Casciola, Elena Gianulis, Sergey Grigoryev, Shu Xiao, Olga N. Pakhomova

Bioelectrics Publications

Nanosecond pulsed electric fields are emerging as a new modality for tissue and tumor ablation. We previously reported that cells exposed to pulsed electric fields develop hypersensitivity to subsequent pulsed electric field applications. This phenomenon, named electrosensitization, is evoked by splitting the pulsed electric field treatment in fractions (split-dose treatments) and causes in vitro a 2- to 3-fold increase in cytotoxicity. The aim of this study was to show the benefit of split-dose treatments for in vivo tumor ablation by nanosecond pulsed electric field. KLN 205 squamous carcinoma cells were embedded in an agarose gel or grown subcutaneously as tumors …

Physical Activity And Survival Among Long-Term Cancer Survivor And Non-Cancer Cohorts, Anthony Gunnell, Sarah Joyce, Stephania Tomlin, Dennis Taaffe, Prue Cormie, Robert Newton, David Joseph, Nigel Spry, Kristjana Einarsdottir, Daniel A. Galvao

Research outputs 2014 to 2021

Evidence suggests physical activity improves prognosis following cancer diagnosis; however, evidence regarding prognosis in long-term survivors of cancer is scarce. We assessed physical activity in 1,589 cancer survivors at an average 8.8 years following their initial diagnosis and calculated their future mortality risk following physical activity assessment. We also selected a cancer-free cohort of 3,145 age, sex, and survey year group-matched cancer-free individuals from the same source population for comparison purposes. Risks for cancer-specific mortality and all-cause mortality in relation to physical activity levels were estimated using Cox regression proportional hazard regression analyses within the cancer and non-cancer cohorts. Physical …

Predictors Of Pneumococcal Carriage And The Effect Of The 13-Valent Pneumococcal Conjugate Vaccination In The Western Australian Aboriginal Population, Deirdre A. Collins, Anke Hoskins, Thomas Snelling, Kalpani Senasinghe, Jacinta Bowman, Natalie A. Stemberger, Amanda J. Leach, Deborah Lehmann

Research outputs 2014 to 2021

Background

The 7-valent pneumococcal conjugate vaccine (PCV7) was introduced to prevent invasive pneumococcal disease (IPD) in Western Australian (WA) Aboriginal people in 2001. PCV13 replaced PCV7 in July 2011, covering six additional pneumococcal serotypes; however, IPD rates remained high in Aboriginal people in WA. Upper respiratory tract pneumococcal carriage can precede IPD, and PCVs alter serotype distribution.

Methods

To assess the impact of PCV13 introduction, identify emerging serotypes, and assess risk factors for carriage, nasopharyngeal swabs and information on demographic characteristics, health, medication and living conditions from Aboriginal children and adults across WA from August 2008 to November 2014 were …

Functions Of Atr/Mec1 In Meiosis And The Cell Cycle, Layne Weatherford

Wayne State University Dissertations

Mec1 is a protein kinase in S. cerevisiae that is critical for the DNA damage checkpoint response, and is the yeast orthologue of the human ATR protein. Cancer cells rely on ATR to arrest the cell cycle and allow sufficient time to repair DNA damage before proceeding through the cell cycle, and ATR inhibitors have been developed as possible anti-cancer agents. DBF4 is the regulatory subunit of DBF4-dependent kinase (DDK) that regulates initiation of DNA replication and is overexpressed in a number of different cancer types. To better understand ATR and DBF4 function, we took advantage of yeast genetics to …

Human Antibody Responses To Pneumococcal Vaccination In Aging Hiv-Positive Individuals, Megan Bickford

MUSC Theses and Dissertations

Introduction: Streptococcus pneumoniae is a major cause of morbidity and mortality in HIV-positive individuals. Despite the widespread use of anti-retroviral medications, the incidence of pneumococcal disease is 20-40 fold higher in the HIV+ population compared to HIV- persons. Consequently, pneumococcal vaccination is recommended for all HIV+ individuals. In 2012 the FDA changed vaccine recommendation from a single vaccination with the 23-valent pneumococcal polysaccharide vaccine (PPV23) to a dual vaccination with 13-valent protein conjugate vaccine (PCV13) followed by PPV23. Studies demonstrating superiority of the PCV13/PPV23 regimen compared to PPV23 alone are limited and controversial. The goal of this study was to …

Using Tcr Transgenic, Gp100 Reactive T Cells And Checkpoint Inhibition To Target Lymphangioleimyomatosis, Christian Ankney

Master's Theses

Lymphangioleiomyomatosis (LAM) is a low-grade neoplastic disease affecting primarily women. It is characterized by cystic lung disease as well as renal and retroperitoneal tumors called angiomyolipomas and lymphangiomas. Tumor cells have smooth muscle features as well as neuroendocrine cell surface markers, and the disease can be diagnosed by HMB45 staining of tumor cells. We questioned whether expression of melanocytic antigens, specifically gp100, creates an opportunity to treat LAM by adoptive T cell transfer. LAM lung lesions demonstrate poor immune surveillance, therefore adoptive T cell transfer could offer benefits in this disease.

A link was made between melanoma and depigmenting vitiligo …

Immunodeficiency-Associated Lymphoid Hyperplasia As A Cause Of Intussusception In A Case Of Activated Pi3k-Δ Syndrome., Daniel Mettman, Isabelle Thiffault, Chitra Dinakar, Carol J. Saunders

Manuscripts, Articles, Book Chapters and Other Papers

Activated PI3K-δ syndrome refers to a recently described primary immunodeficiency syndrome consisting of recurrent sinopulmonary infections, lymphadenopathy, mucosal lymphoid aggregates, increased susceptibility to Epstein-Barr virus and cytomegalovirus, and increased incidence of B-cell lymphomas. Variants in PIK3CD, which encodes the phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta isoform, enhance membrane association and kinase activity, resulting in increased signal transduction through the PI3K-Akt pathway. Whole-exome sequencing revealed a pathogenic PIK3CD variant in a patient with history of immunologic impairment, recurrent sinopulmonary infections, and lymphoid hyperplasia presenting as intussusception. This case illustrates that while lymphoid hyperplasia secondary to immunodeficiency is most often unsurprising and …
