Dispelling The Malaria-Typhoid Co-Infection Myth In Nigeria. A Literature Review, Olawale Akinola

Dartmouth Library Staff Publications

Malaria and typhoid fever are public health concerns in Nigeria, with high prevalence rates. The perception of a widespread co-infection between these diseases may be misleading, due to limitations in diagnostic methods, particularly the Widal test for typhoid fever. This literature review examines the prevalence of malaria-typhoid co-infection in Nigeria and identifies factors contributing to misdiagnosis, including non-specific symptoms, limited diagnostic resources, and the diagnostic accuracy of tests employed. Additionally, the review discusses the implications of misdiagnosis, such as the overuse of broad-spectrum antibiotics leading to a rising incidence of antimicrobial resistance. Strategies to address this issue are explored, emphasizing …

Structural Homology Of Mite Profilins To Plant Profilins Is Not Indicative Of Allergic Cross-Reactivity, Andrea O'Malley, Sahana Sankaran, Avery Carriuolo, Kriti Khatri, Krzysztof Kowal, Maksymilian Chruszcz Ph.D.

Faculty Publications

Structural and allergenic characterization of mite profilins has not been previously pursued to a similar extent as plant profilins. Here, we describe structures of profilins originating from Tyrophagus putrescentiae (registered allergen Tyr p 36.0101) and Dermatophagoides pteronyssinus (here termed Der p profilin), which are the first structures of profilins from Arachnida. Additionally, the thermal stabilities of mite and plant profilins are compared, suggesting that the high number of cysteine residues in mite profilins may play a role in their increased stability. We also examine the cross-reactivity of plant and mite profilins as well as investigate the relevance of these profilins …

Cancer nanomedicine has been facilitated through nanoparticle-based (NP-based) delivery systems which can combat NSCLC via recent advances in nanotechnology and apply its benefits to existing drugs. An effective therapeutic solution could be gained via repurposing and accelerated via NP-based drug delivery systems. This review aims to present an overview of NSCLC treatments with a special focus on drug repurposing with details of clinical study advances and NP-based drug delivery systems for NSCLC. …

Spectrophotometric Device For Early Malaria Detection, Adrian Wasylewski, Christopher Faber, Victor Lin

Honors Thesis

Malaria remains a significant global health challenge, with millions of cases reported annually, particularly in resource-limited regions. Timely and accurate diagnosis is crucial for effective treatment and disease management. Unfortunately, there are still significant challenges in existing testing procedures, which are often expensive, inaccurate, or impractical for mass testing. While spectrophotometry has been proposed as a detection tool for other tropical diseases such as dengue fever, no prototype has been made for any disease, including malaria. This report addresses this gap by presenting a spectrophotometric-based malaria detection tool that achieves high sensitivity at a low cost. The inclusion of a …

A Phenomenological Examination Of The Experiences Of College Theater Majors In Regard To The Covid-19 Pandemic And Lockdowns In The United States, Ronda Celeste Jones

Doctoral Dissertations and Projects

The COVID-19 pandemic and resulting lockdowns were phenomena experienced by the majority of the modern world, but not everyone experienced it in the same way. Each person brings their own past, their own interests, and their own needs to the lived experience. Pre-pandemic research on art therapy suggests that creative expression could be helpful to adolescents experiencing such trauma. Theater majors are a particular set of people for whom creative expression through theater is a huge part of their life. Theater majors are also participating in a creative activity that requires social contact, and that social contact was limited or …

Herpes Simplex Keratitis After Prk, Joshua Graf Od

Optometric Clinical Practice

Background: Herpes simplex virus (HSV) is a double stranded DNA virus that infects much of the world’s population. The World Health Organization estimates 67% of people under the age of 50 have HSV-1 and 11% of people under the age of 50 have HSV-2. While most systemic infections remain inactive and do not cause symptoms, the activation and appearance of ocular HSV can be a destructive and vision-threatening issue. HSV keratitis can be epithelial, stromal or a combination. Patients who have recently undergone photorefractive keratectomy (PRK) have a higher risk of HSV keratitis. Because of this, HSV keratitis should be …

Division of Infectious Diseases and Environmental Medicine Faculty Papers

The coronavirus disease of 2019 (COVID-19) pandemic exacerbated barriers to care for people living with human immunodeficiency virus (HIV) (PLWH). The quick uptake of telemedicine in the outpatient setting provided promise for care continuity. In this study, we compared appointment and laboratory no-show rates in an urban outpatient HIV clinic during three time periods: (1) Pre-COVID-19: 9/15/2019-3/14/2020 (predominately in-person), (2) "Early" COVID-19: 3/15/2020-9/14/2020 (predominately telemedicine), and (3) "Later" COVID-19: 9/15/2020-3/14/2021 (mixed in-person/telemedicine). Multivariable logistic regression models evaluated the two study hypotheses: (i) equivalence of Period 2 with Period 1 and of Period 3 with Period 1 and (ii) improved outcomes …

How Dna Reveals God’S Design, Alan L. Gillen

Faculty Publications and Presentations

Codes are big in today’s world: QR codes, barcodes, computer codes, cell phone codes, and more. Specific information is needed to identify, diagnose, and inform. DNA is the code for life: microbes, plants, parasites, animals, and man. DNA Day is April 25 because it was this day in history (April 25, 1953) when James Watson and Francis Crick described DNA as the double helix and the code for life. Although we consider DNA the genetic blueprint for life, it has only been known for 80 years. On February 1, 1944, Oswald Avery, Colin MacLeod, and Maclyn McCarty wrote a revolutionary …

Probing Medicinal Plants For Novel Antimicrobial Compounds, Nolan Brezina, Gracie Holt, Daileen Serrano, Jenna Yehyawi

Symposium on Research and Creative Expression (SORCE)

According to the W.H.O., infectious diseases account for three of the top ten global causes of death. Antimicrobial drug discovery surged in the mid-twentieth century but has sharply declined in recent years. At the same time, antimicrobial-resistant “superbug” infections are on the rise. Plants produce a robust supply of novel metabolic compounds, including many antimicrobial agents. However, with the advent of modern antibiotic drugs, natural plant-derived antibiotic sources have largely been left unexplored. Therefore, our work is focused on screening poorly explored medicinal plants in the hopes of discovering novel antimicrobial drugs. To do this, we have been testing extracts …

Euhaplorchis Sp. A Effect On Social Behavior And Familiarity Of Gulf Killifish (Fundulus Grandis), Hannah Bauman

All HCAS Student Capstones, Theses, and Dissertations

Trophically transmitted parasites may manipulate their hosts’ phenotype (e.g., behavior, physiology, morphology) to increase the likelihood of transmission to the definitive host. In fishes, stable social groups develop familiarity over time through repeated interactions among individuals, and social preferences are often developed due to familiarity. Consequently, fishes often shoal with familiar fishes, a behavior that is likely to be protective against predation. Parasites may alter fish social dynamics in two ways: by decreasing association with familiar individuals, thereby isolating infected fish and making them more susceptible to predation by definitive hosts; and/or by incentivizing uninfected individuals to avoid infected fish …

Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig

Thinking Matters Symposium

Neutrophils, also called polymorphonuclear leukocytes (PMNs), constitute the majority of innate immune cells. These cells possess a complex arsenal of functions that allow them to detect and eliminate a broad spectrum of pathogens. Neutropenia is characterized by decreased levels of neutrophils in the bloodstream, typically falling below the normal range. Moderate to severe neutropenia can increase the risk of pathogenic infections and without treatment can be life-threatening. Although the concentration of neutrophils in neutropenic individuals is decreased, upon activation, neutrophils still release neutrophil extracellular traps (NETs). NETs are pivotal in combating a spectrum of pathogens through their non-selective nature. Overreactive …

Amplon: Amplifying Dna With Multiarm Priming And Looping Optimization Of Nucleic Acid, Mert Tunca Doganay, Ethan Roman, Andrea M. Hujer, Robert A. Bonomo, Mohamed S. Draz

Faculty Scholarship

Nucleic acid amplification, the bedrock of biotechnology and molecular diagnostics, surges in applications—especially isothermal approaches—heightening the demand for advanced and precisely engineered methods. Here, a novel approach for amplifying DNA with multiarm priming and looping optimization of nucleic acid (AMPLON) is presented. AMPLON relies on a novel polymeric material with unique set of multiarm polyethylene glycol–DNA primers for efficient DNA amplification under isothermal conditions. Each arm carries single-stranded DNA complementing the sense or antisense sequence of the target DNA. The amplification reaction begins with antisense arms binding to the target DNA, forming a template for sense-carrying arms to direct multiarm …

Towards A Study Protocol: A Data-Driven Workflow To Identify Error Sources In Direct Ink Write Mechatronics, Hein Htet Aung, Quynh D. Tran, Pawan Tripathi, Roger H. French, Laura S. Bruckman

Faculty Scholarship

Using Direct Ink Write (DIW) technology in a rapid and large-scale production requires reliable quality control for printed parts. Data streams generated during printing, such as print mechatronics, are massive and diverse which impedes extracting insights. In our study protocol approach, we developed a data-driven workflow to understand the behavior of sensor-measured X- and Y-axes positional errors with process parameters, such as print velocity and velocity control. We uncovered patterns showing that instantaneous changes in the velocity, when the build platform accelerates and decelerates, largely influence the positional errors, especially in the X-axis due to the hardware architecture. Since DIW …

Faculty, Staff and Students Publications

Human noroviruses, globally the main cause of viral gastroenteritis, show strain specific affinity for histo-blood group antigens (HBGA) and can successfully be propagated ex vivo in human intestinal enteroids (HIEs). HIEs established from jejunal stem cells of individuals with different ABO, Lewis and secretor geno- and phenotypes, show varying susceptibility to such infections. Using bottom-up glycoproteomic approaches we have defined and compared the N-linked glycans of glycoproteins of seven jejunal HIEs. Membrane proteins were extracted, trypsin digested, and glycopeptides enriched by hydrophilic interaction liquid chromatography and analyzed by nanoLC-MS/MS. The Byonic software was used for glycopeptide identification followed by hands-on …

Pharmacy Faculty Articles and Research

The emergence of multidrug-resistant (MDR) strains causes severe problems in the treatment of microbial infections owing to limited treatment options. Antimicrobial peptides (AMPs) are drawing considerable attention as promising antibiotic alternative candidates to combat MDR bacterial and fungal infections. Herein, we present a series of small amphiphilic membrane-active cyclic peptides composed, in part, of various nongenetically encoded hydrophilic and hydrophobic amino acids. Notably, lead cyclic peptides 3b and 4b showed broad-spectrum activity against drug-resistant Gram-positive (MIC = 1.5–6.2 µg/mL) and Gram-negative (MIC = 12.5–25 µg/mL) bacteria, and fungi (MIC = 3.1–12.5 µg/mL). Furthermore, lead peptides displayed substantial antibiofilm action comparable …
