DePaul Magazine

Researchers at DePaul's Center for Community Research are mapping the brain to uncover the causes of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). Psychologist Leonard Jason has been carrying out community-based epidemiology prevalence studies that show that about one million Americans, many of them from ethnic minorities, are afflicted with the condition.

Understanding Immunometabolic And Suppressive Factors That Impact Cancer Development, Rebecca Swearingen Hesterberg

USF Tampa Graduate Theses and Dissertations

The immune system is responsible for surveillance against pathogens and malignancies and adoptive transfer of antigen-specific T is a powerful new cancer treatment option. There is a clinical need to understand more about the normal regulatory processes that prevent immunosurveillance and how to manipulate this for clinical benefit. This project aims to understand T cells from three different angles. First, the biological role of the negative regulator cereblon (CRBN) was investigated in CD8+ T cells and my studies showed that higher levels of specific derivatives downstream of the amino acid glutamine may be beneficial to T cells in the immune …

Mechanisms To Regulate Genes Encoding Clinically Relevant Multidrug Transporters At The Crossroads Of Antibiotic Resistance And Oxidative Stress Detection, Afsana Sabrin

LSU Doctoral Dissertations

Multiple Antibiotic Resistance Regulators (MarRs) are DNA binding proteins involved in bacterial survival and pathogenesis. My PhD dissertation focuses on a MarR homolog, OstR, which regulates genes encoding major multidrug transporters, a resistance-nodulation-division (RND) and an E. coli multidrug resistance B (EmrB) efflux pump homolog in Burkholderia thailandensis. The ostR gene is divergently oriented from genes encoding a hypothetical protein (Hyp) and an RND transporter and adjacent to a gene encoding an EmrB transporter. OstR binds to the promoters of each gene (K_d = 64.9 ± 8.0 nM, K_d = 126.1 ± 10.9 nM and K …

The Deadly Influenza Virus And Its Changing Forms, Kayce Boggess

D.U.Quark

The influenza virus has plagued humans for centuries. Recently antiviral medications, which shorten the duration of the flu, have been introduced into society. These medications along with vaccinations, which try to give the body immunity before the virus strikes, help to stop the flu before it attacks the host. The virus, however, replicates using host cells and can slightly change itself with each replication, which over time could lead to a strain immune to the current antiviral medication and vaccines. However, using more preventative measures could help slow the changing strains of the flu virus. Using vaccines to stop the …

Background: Adults who suffer with severe and persistent mental illness (SPMI) rarely access medical care to receive preventive vaccines. Aims: To increase the rate of vaccines among the SPMI population in an outpatient community mental health center (CMHC). Methods: A review of the literature identified a gap between the general population and SPMI clients in receiving preventive vaccinations. An initial mixed-method convenience survey of SPMI clients (n = 392) provided information on current vaccination status, demographics, beliefs, and interest in receiving vaccines. A vaccination program was developed to address identified barriers and increase vaccination rates. Postintervention data were collected …

Can Assisted Reproductive Technologies Help Conserve 300 Million Years Of Evolution? A First Attempt At Developing These Technologies For Male Reptiles, Sean M. Perry

LSU Doctoral Dissertations

Biodiversity loss is the most critical environmental problem threatening ecosystem, animal, and human health today. Increases in extinction rates have been observed over the past 50 years, with reptile losses occurring twelve times faster than traditional extinction rates. This demonstrated biodiversity loss is secondary to climate change, habitat destruction, infectious disease, invasive species, poaching, and unsustainable trade. Approximately 20% of all reptiles are threatened with extinction and population declines are approaching rates similar to the current amphibian extinction crisis. Preventing the extinction of reptiles will require humans to acknowledge these losses and develop plans to preserve these evolutionary sentinel species. …

Complex Microbiome In Brain Abscess Revealed By Whole-Genome Culture-Independent And Culture-Based Sequencing., Jyun-Hong Lin, Zong-Yen Wu, Liang Gong, Chee-Hong Wong, Wen-Cheng Chao, Chun-Ming Yen, Ching-Ping Wang, Chia-Lin Wei, Yao-Ting Huang, Po-Yu Liu

Faculty Research 2019

Brain abscess is a severe infectious disease with high mortality and mobility. Although culture-based techniques have been widely used for the investigation of microbial composition of brain abscess, these approaches are inherent biased. Recent studies using 16S ribosomal sequencing approaches revealed high complexity of the bacterial community involved in brain abscess but fail to detect fungal and viral composition. In the study, both culture-independent nanopore metagenomic sequencing and culture-based whole-genome sequencing using both the Illumina and the Nanopore platforms were conducted to investigate the microbial composition and genomic characterization in brain abscess. Culture-independent metagenomic sequencing revealed not only a larger …

Favorable Outcomes With Ventricular Assist Device Exchange, Megan Carroll, Meghan Tooman, Markian Bochan, Christopher Salerno, Ashwin Ravichandran

The VAD Journal

Left ventricular assist device (LVAD) therapy remains a vital therapeutic option for patients with end-stage heart failure. Unfortunately, adverse events can occur and progress to require consideration for device exchange once the failure of medical management becomes evident, especially when heart transplantation is not possible in a timely manner. The aim of this analysis is to describe the incidence and outcomes of LVAD exchanges at our institution. Between April 2008 and May 2017, 397 patients underwent LVAD implantation, with 32 of those patients subsequently receiving exchange upon the recommendation of our multidisciplinary team due to refractory infection (n=12), device malfunction …

Serum Amyloid P Component Binds Fungal Surface Amyloid And Decreases Human Macrophage Phagocytosis And Secretion Of Inflammatory Cytokines, Nicole E. Behrens, Peter N. Lipke, Darrell Pilling, Richard H. Gomer, Stephen A. Klotz

Publications and Research

In patients with invasive fungal diseases, there is often little cellular inflammatory response. We tested the idea that binding of the human constitutive plasma protein serum amyloid P component (SAP) (also called PTX2) to Candida albicans dampens the innate immune response to this fungus. Many pathogenic fungi have cell surface amyloid-like structures important for adhesion and biofilm formation. Human SAP bound to fungi that expressed functional cell surface amyloid, but SAP had minimal binding to fungi with reduced expression of cell surface amyloid. In the absence of SAP, phagocytosis of fungi by human macrophages was potentiated by expression of amyloid …

Obstetrics and Gynaecology, East Africa

Background: Rapid demographic, epidemiological, and nutritional transitons have brought a pressing need to track progress in adolescent health. Here, we present country-level estimates of 12 headline indicators from the Lancet Commission on adolescent health and wellbeing, from 1990 to 2016.

Methods: Indicators included those of health outcomes (disability-adjusted life-years [DALYs] due to communicable, maternal, and nutritional diseases; injuries; and non-communicable diseases); health risks (tobacco smoking, binge drinking, overweight, and anaemia); and social determinants of health (adolescent fertility; completion of secondary education; not in education, employment, or training [NEET]; child marriage; and demand for contraception satisfied with modern methods). We drew …

Improving Risk Assessment Of The Emergence Of Novel Influenza A Viruses By Incorporating Environmental Surveillance, Kim M. Pepin, Matthew W. Hopken, Susan A. Shriner, Erica Spackman, Zaid Abdo, Colin Parrish, Steven Steven, James O. Lloyd-Smith, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Reassortment is an evolutionary mechanism by which influenza A viruses (IAV) generate genetic novelty. Reassortment is an important driver of host jumps and is widespread according to retrospective surveillance studies.However, predicting the epidemiological risk of reassortant emergence in novel hosts from surveillance data remains challenging. IAV strains persist and cooccur in the environment, promoting co-infection during environmental transmission. These conditions offer opportunity to understand reassortant emergence in reservoir and spillover hosts. Specifically, environmental RNA could provide rich information for understanding the evolutionary ecology of segmented viruses, and transform our ability to quantify epidemiological risk to spillover hosts. However, significant challenges …

Evaluation Of A Self-Adjuvanted Self-Assembling Protein Nanoparticle As A Platform For Vaccine Development, Sarah Low

Doctoral Dissertations

Vaccines are one of the most impactful inventions in modern medicine and are responsible for significant improvements in public health. While various vaccine types are available, subunit vaccines have substantial interest in the field. Typical subunit vaccines are advantageous because they are considered safe; however, they often do not elicit strong immune responses because they cannot crosslink B cell receptors. To overcome this, repetitive display systems are used. Here we study an exciting platform called Self-Assembling Protein Nanoparticles (SAPNs), which contain coiled-coil oligomerization domains that self-assemble into nanoparticles similar in size and shape to icosahedral viruses. Previous work has demonstrated …

The Use Of Guided Imagery To Enhance Power For Smoking Behavior Change, Christine A. Wynd

Dissertations

Cigarette smoking is known to be a risk factor in several fatal disease syndromes. Despite increasing knowledge of the danger, thirty-one percent of all Americans continue to smoke (Thornberry et al., 1986). Individual responsibility for behavioral change is indicated for successful, long-term smoking abstinence. However, there is need for continued systematic study of interventions which assist clients in their pursuit of healthier lifestyle change. The purpose of this study was to determine the effectiveness of guided imagery for enhancing client power relevant to smoking behavior change.

Reflecting On Efforts To Design An Inclusive Citizen Science Project In West Baltimore, Amanda E. Sorensen, Rebecca C. Jordan, Shannon L. Ladeau, Dawn Biehler, Sacoby Wilson, John-Henry Pitas, Paul T. Leisnham

School of Natural Resources: Faculty Publications

Citizen science (CS) has been an increasingly utilized means by which scientists leverage members of the public to increase the amount of data collected and analyzed. However, the underrepresentation of individuals from certain socio-cultural groups can have consequences that can manifest in the scientific outcomes of those CS projects such as biases in the data. Additionally, this underrepresentation can potentially affect long-term viability and support of CS as a community of practice. CS programs that promote greater inclusivity would likely provide opportunities for communities to define, investigate, and address pressing issues in collaboration with professional scientists. In this paper we …

Cationic Antimicrobial Peptides: Alternatives And/Or Adjuvants To Antibiotics Active Against Methicillin-Resistant Staphylococcus Aureus And Multidrug-Resistant Pseudomonas Aeruginosa, Regina Geitani, Carole Ayoub Moubareck, Lhousseine Touqui, Dolla Karam Sarkis

All Works

© 2019 The Author(s). Background: Methicillin-resistant Staphylococcus aureus and multidrug-resistant Pseudomonas aeruginosa are becoming difficult to treat with antibiotics whereas Cationic Antimicrobial Peptides (CAMPs) represent promising alternatives. The effects of four CAMPs (LL-37: human cathelicidin, CAMA: cecropin(1-7)-melittin A(2-9) amide, magainin-II and nisin) were investigated against clinical and laboratory S. aureus (n = 10) and P. aeruginosa (n = 11) isolates either susceptible or resistant to antibiotics. Minimal Inhibitory Concentrations (MICs), Minimal Bactericidal Concentrations (MBCs), and bacterial survival rates (2 h post-treatment) were determined by microbroth dilution. The antipseudomonal effects of the antibiotics colistin or imipenem combined to LL-37 or CAMA …

Global Monitoring Of Antimicrobial Resistance Based On Metagenomics Analyses Of Urban Sewage, Rene S. Hendriksen, Patrick Munk, Patrick Njage, Bram Van Bunnik, Luke Mcnally, Oksana Lukjancenko, Timo Röder, David Nieuwenhuijse, Rumina Hasan, Sadia Shakoor

Department of Pathology and Laboratory Medicine

Antimicrobial resistance (AMR) is a serious threat to global public health, but obtaining representative data on AMR for healthy human populations is difficult. Here, we use metagenomic analysis of untreated sewage to characterize the bacterial resistome from 79 sites in 60 countries. We find systematic differences in abundance and diversity of AMR genes between Europe/North-America/Oceania and Africa/Asia/South-America. Antimicrobial use data and bacterial taxonomy only explains a minor part of the AMR variation that we observe. We find no evidence for cross-selection between antimicrobial classes, or for effect of air travel between sites. However, AMR gene abundance strongly correlates with socio-economic, …

Kinetic Analysis And Epitope Mapping Of Monoclonal Antibodies To Salmonella Typhimurium Flagellin Using A Surface Plasmon Resonance Biosensor, Devendra Bhandari, Fur-Chi Chen, Shreya Hamal, Roger C. Bridgman

Human Sciences Faculty Research

Salmonella Typhimurium is one of the leading causes of foodborne diseases worldwide. Biosensors and immunoassays utilizing monoclonal antibodies are widely used for the detection and subtyping of S. Typhimurium. However, due to insufficient information on the nature of binding with S. Typhimurium flagellin, the selection of appropriate antibodies for assay development is a cumbersome task. Hence, we aimed to compare the binding kinetics of a panel of monoclonal antibodies and their relative binding sites to flagellin antigen using a surface plasmon resonance biosensor. Initially, the flagellin was captured on the sensor surface through an immobilized anti-flagellin antibody. The interactions of …

Ondondo, Sheryl Van Der Poel, Mary A. Guze, Starley B. Shade, Elizabeth A. Bukusi, Deborah Cohan, Craig R. Cohen

Obstetrics and Gynaecology, East Africa

Background: Female positive/male negative HIV-serodiscordant couples express a desire for children and may engage in condomless sex to become pregnant. Current guidelines recommend antiretroviral treatment in HIV-serodiscordant couples, yet HIV RNA viral suppression may not be routinely assessed or guaranteed and pre-exposure prophylaxis may not be readily available. Therefore, options for becoming pregnant while limiting HIV transmission should be offered and accessible to HIV-affected couples desiring children.

Methods: A prospective pilot study of female positive/male negative HIV-serodiscordant couples desiring children was conducted to evaluate the acceptability, feasibility, and effectiveness of timed vaginal insemination. Eligible women were 18-34 years with regular …

Reasons For Vaccine Declination In Healthy Individuals Attending An International Vaccine And Travel Clinic, Timothy L. Wiemken, Julio A. Ramirez, Ruth M. Carrico

Journal of Refugee & Global Health

Little is known about the vaccine-related health behaviors of healthy individuals. We surveyed healthy individuals attending a vaccine center to define the reasons behind vaccine declination when the vaccine is warranted under current guidance. Declination due to perceived risks of the vaccines were by far the most common rationale, suggesting continued need for public health educational campaigns.
