The Inside Scoop: Elucidating The Three-Way Relationship Between Schistosoma Mansoni, The Gut, And Vaccines, Mariam A. Mhanna

Biomedical Sciences Theses & Dissertations

Schistosomiasis is a neglected tropical disease that affects over 250 million people worldwide. This blood fluke infection burdens communities and areas with limited to no access to clean fresh water. When a host is exposed to cercariae, the infectious agent, in a body of water, it matures in the host’s circulation into adult female and male worms. Copulated adult worms migrate to the mesentery, in the case of Schistosoma mansoni, and produce eggs that can cross the intestinal barrier and get excreted in the feces to continue the lifecycle. The effects of S. mansoni infection on the host …

Massively Parallel Immunopeptidome By Dna Sequencing Provides Insights Into Cancer Antigen Presentation, Quanming Shi, Cheryl F Lichti, Et Al.

2020-Current year OA Pubs

Human leukocyte antigens (HLAs) are encoded by the most polymorphic genes in the human genome. HLA class I alleles control antigen presentation for T cell recognition, which is pivotal for autoimmunity, infectious diseases and cancer. Current knowledge of HLA-bound peptides is limited, skewed and falls short of population-wide HLA binding profiles for high-value targets. Here we present ESCAPE-seq (enhanced single-chain antigen presentation sequencing), a massively parallel platform for comprehensive screening of class I HLA-peptide combinations for antigen presentation via deep DNA sequencing. ESCAPE-seq demonstrates programmability, high throughput, sensitivity and nominated viral and cancer epitopes. We simultaneously assessed over 75,000 peptide-HLA …

Is “Pre-Sepsis” The New Sepsis? A Narrative Review, Rémy Gerard, Antoine Dewitte, Fridolin Gross, Thomas Pradeu, Maël Lemoine, Julien Goret, Maria Mamani-Matsuda

Presidential Fellows Articles and Research

Sepsis is a life-threatening condition caused by a dysregulated immune response to infection, leading to organ dysfunction and high mortality. Despite advances in treatment, sepsis remains difficult to manage. Historically, the concept of sepsis evolved from ancient observations of infection-related decay to the germ theory of the 19th century. The latest Sepsis-3 definition describes sepsis as life-threatening organ dysfunction due to a dysregulated host response. However, this clinical characterization may be too late for effective intervention. The concept of endotypes and the ontological data applied to sepsis highlight the substantial heterogeneity in pathophysiological pathways leading to this endpoint. We propose …

Influences Of The Western Press On News Framing Of Global Events In Developing Countries: Examining Covid-19 And Climate Coverage In A Bangladeshi News Organization, Arif Md Tareque Habib

Communication ETDs

This study shows that a small number of Western news organizations (e.g., Reuters, The New York Times) may influence how local news organizations in developing countries frame global crises and that this influence may lead local news organizations to ignore locally relevant aspects of those crises. To test this thesis, two studies were conducted on the coverage of two crises -- COVID-19 and climate change -- by a news organization in Bangladesh, a developing country in South Asia. The news organization, www.bdnews24.com, serves both as a news agency or news supplier for local newspapers and an online newspaper for users. …

Effective And Eco-Friendly Strategies To Control Birds In Industrial Estate, Jasti Rahayu, Upik K. Hadi, Susi Soviana

Journal of Environmental Science and Sustainable Development

Bird infestations in industrial areas can cause infrastructure damage, contamination, and health risks. Despite these impacts, they are rarely addressed in environmental management strategies. At the Kaltim Industrial Estate (KIE) in Bontang, East Kalimantan, synanthropic bird species that thrive in human-altered environments have become persistent nuisances, particularly because of structural opportunities for roosting and altered ecological conditions. To address this issue, this study applied Integrated Pest Bird Management (IPBM), a non-lethal and environmentally friendly approach that combines species identification, behavior analysis, and targeted deterrents. IPBM was selected for its adaptability to industrial settings and its alignment with sustainable development goals. …

This study used immunoinformatics to identify candidate epitopes for a multiepitope vaccine construct against H. pylori.

Material and methods: The protein variability server was utilized for conservation analysis. The epitopes were screened for antigenicity, allergenicity, toxicity, cross-reactivity, and population coverage. Selected epitopes were docked with their corresponding human leukocyte antigen (HLA) alleles, and thermodynamic quantities were determined. Five virulence …

Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk

Biology ETDs

Research on Physella acuta, an invasive freshwater snail, reveals insights into its parasitology, fitness, and molecular biology. Morphological and molecular analyses revealed two distinct mitogenomic lineages, local (B) and invasive (A) strains of native P. acuta, both having comparable trematode infection rates, suggesting that the low infection rates observed from A in invaded regions result from "enemy release" rather than immune incompatibility. Fitness assessments showed that while lineages A and B performed similarly under laboratory conditions, rewilding experiments revealed significantly higher fitness in lineage A. Transcriptomic profiling supported these differences, with A snails showing greater immune-related gene expression and …

Some Corrections To The Record On Lemkin’S Early Years: The Evidence From Poland, Zachary Mazur

Genocide Studies and Prevention: An International Journal

This piece addresses some misunderstandings regarding Raphael Lemkin's early years in Poland, his influences and the development of his ideas. While discussing some of the extent published information, I point out what other archival documents from Poland and the League of Nations have to say about Lemkin's past. One of the main points is that Lemkin was an unreliable narrator on his own life, and this has caused confusion.

Immune Regulation In Fungal Airway Inflammation And Host Defense, Ruoning Wang

Biomedical Sciences ETDs

Asthma is a chronic inflammatory disease of the lungs characterized by complex pathophysiological mechanisms and diverse endotypes, primarily categorized as T helper type 2 cell (Th2)-high and Th2-low asthma. Despite significant advances in understanding asthma pathogenesis, the mechanisms governing the pulmonary immune system’s response to external challenges have not been fully understood. To address these gaps, this comprehensive project was designed to investigate the interplay between fungal infections and specific CD4⁺ T cell populations in asthma. Our findings suggest that fungal infections can contribute to neutrophilic asthma by promoting the migration of platelet-myeloid aggregates into the lungs. We also …

Faculty, Staff and Student Publications

Neutrophils play a key role in autoimmune diseases like rheumatoid arthritis, contributing to tissue damage through rapid recruitment and activation. In this study, we investigated the regulatory properties of two receptor-like tyrosine phosphatases (RPTPs), CD45 and CD148, in inflammatory arthritis. Using an in vivo mouse model of K/BxN serum transfer-induced arthritis, we found that CD45 and CD148 feature distinct regulatory properties during inflammatory arthritis. CD45 is required for neutrophil infiltration, cytokine release, and reactive oxygen species production, whereas CD148 deficiency leads to a delayed onset of arthritis but unaltered overall neutrophil infiltration and reduced ROS production. Furthermore, we could demonstrate …

Constitutionalizing Traveling Feminisms In Kenya, Nkatha Kabira

Cornell International Law Journal

This Article uses selected provisions of the Constitution of Kenya 2010 to argue that although elaborate legal and institutional frameworks for promoting women’s empowerment have been adopted in Kenya’s legal framework, implementation of these provisions remains a challenge. Why is the law in the books so different from the law in action? This is the question this Article seeks to address. By mapping out how feminist ideas travel through collective action, colonial encounters, local, regional and world conferences, legislation, and other means, the Article demonstrates that the reason why implementation remains a challenge is that these ideas are often in …

Optimization And Model Averaging Of Histogram-Based Place Cell Firing Rate Maps Using The Point Process Framework, Murat Okatan

Turkish Journal of Electrical Engineering and Computer Sciences

The firing rate of hippocampal place cells depends on the spatial position of the organism in an environment. This position dependence is often quantified by constructing spike-in-location and time-in-location histograms, the ratio of which yields a firing rate map. The purpose of this study is to present a new method for optimizing the spatial resolution of histogram-based firing rate maps. It is pointed out that histogram-based firing rate maps are conditional intensity functions of inhomogeneous Poisson process models of neural spike trains, and, as such, they can be optimized through model selection within the point process framework. The point process …
