BACKGROUND: Loiasis is a disease caused by the nematode Loa loa. Serious adverse events sometimes occur in people with heavy L. loa microfilaremia after ivermectin treatment. In regions of Central Africa where loiasis is endemic, this significantly impedes global elimination programs for lymphatic filariasis and onchocerciasis that use mass distribution of ivermectin. Improved diagnostic tests to identify individuals at increased risk of serious adverse events could facilitate efforts to eliminate lymphatic filariasis and onchocerciasis in this region.

METHODS AND FINDINGS: We previously identified the L. loa protein Ll-Bhp-1 in loiasis patient sera. Here, we further characterize Ll-Bhp-1 and report development …

School of Medicine Publications

There has been a surge of interest in recent years in understanding the intricate mechanisms underlying cancer progression and treatment resistance. One molecule that has recently emerged in these mechanisms is MUC13 mucin, a transmembrane glycoprotein. Researchers have begun to unravel the molecular complexity of MUC13 and its impact on cancer biology. Studies have shown that MUC13 overexpression can disrupt normal cellular polarity, leading to the acquisition of malignant traits. Furthermore, MUC13 has been associated with increased cancer plasticity, allowing cells to undergo epithelial-mesenchymal transition (EMT) and metastasize. Notably, MUC13 has also been implicated in the development of chemoresistance, rendering …

Developmental and epileptic encephalopathies (DEEs) feature altered brain development, developmental delay and seizures, with seizures exacerbating developmental delay. Here we identify a cohort with biallelic variants in DENND5A, encoding a membrane trafficking protein, and develop animal models with phenotypes like the human syndrome. We demonstrate that DENND5A interacts with Pals1/MUPP1, components of the Crumbs apical polarity complex required for symmetrical division of neural progenitor cells. Human induced pluripotent stem cells lacking DENND5A fail to undergo symmetric cell division with an inherent propensity to differentiate into neurons. These phenotypes result from misalignment of the mitotic spindle in apical neural progenitors. Cells …

New Imidazolidindionedioximes And Their Pt(Ii) Complexes: Synthesis And Investigation Of Their Antitumoral Activities On Breast Cancer Cells, Emrah Karahan, Tuğba Gençoğlu Katmerli̇kaya, Emel Önal, Aydan Dağ, Ayşe Gül Gürek, Vefa Ahsen

Turkish Journal of Chemistry

Breast cancer is one of the most common types of cancer worldwide and has the most lethality ratio for females among all cancers. Although current cancer therapeutics have made considerable advancements, there is still room for improvement in terms of efficacy. Many anticancer drugs have a risk of causing serious adverse effects due to their non-specific cytotoxic effects on both tumor and healthy cells. New therapeutics might have a greater ability to kill cancer cells, reduce the volume of tumors, and improve overall therapy response rates. Herein, we report the efficient synthesis and characterization of three amphi vic-dioximes and their …

Synthesis Of Addressable Libraries: New Lessons And The Need For Proper Characterization For Microelectrode Array-Based Reactions, Albert Huang

Arts & Sciences Graduate Student Theses and Dissertations

The Moeller group has been developing synthetic tools for building molecular libraries on microelectrode arrays since 2004. Such a library is intriguing because one can take advantage of the library for biological signaling studies. Microelectrode arrays can serve as a powerful platform for those experiments since every electrode in the array can be addressed individually. Unique members of the library targeting biological receptors that one is interested in can be restricted only above unique electrodes in an array. Thus, high-affinity ligands for those receptors can be identified with this strategy. To make this method work, one has to make sure …

Using Phylogenomics And Environmental Metabarcoding To Understand The Distribution And Evolutionary Histories Of Amoebae, Robert E. Jones

Theses and Dissertations

Protists are defined as eukaryotic organisms that are not animals, land plants, or fungi and make up the vast majority of eukaryotic diversity. Unfortunately, they are often overlooked and under sampled. Some rationales behind this are that they are often microscopic, most rarely the cause of human disease, and are often difficult to get into culture. Molecular phylogenetics has revolutionized our understanding of the evolutionary history of eukaryotes and without a clear picture of protist evolution our understanding would be severely hindered. Phylofisher is an easy-to-use phylogenomic software package, with an accompanying database and various utilities, intended for deep phylogenomic …

Anthropology Faculty Publications and Presentations

Abstract We present the first open-access, island-wide isotopic database (IsoMad) for modern biologically relevant materials collected on Madagascar within the past 150 years from both terrestrial and nearshore marine environments. Isotopic research on the island has increasingly helped with biological studies of endemic organisms, including evaluating foraging niches and investigating factors that affect the spatial distribution and abundance of species. The IsoMad database should facilitate future work by making it easy for researchers to access existing data (even for those who are relatively unfamiliar with the literature) and identify both research gaps and opportunities for using various isotope systems to …

Elucidating The First Protective Mutation From Inherited Alzheimer’S Disease - Apolipoprotein E3 Christchurch (Apoe3ch) And Insights Into Apoe Ligand-Receptor Interactions, Yun Chen

Arts & Sciences Graduate Student Theses and Dissertations

Alzheimer’s disease (AD) is the major cause of dementia. An inherited form of AD (dominant inherited AD) starts much earlier in life, often in the fourth and fifth decade. A recent case report described an individual who was resistant to dominantly inherited AD caused by a PSEN1-E280A mutation and was a homozygous carrier of the APOE3 Christchurch (APOE3ch) variant. A clear separation between amyloid and tau pathology occurred in this unique AD case. However, whether APOE3ch contributed to the protective effect remains unclear. In this thesis, we generated a humanized APOE3ch knock-in mouse and crossed it to an amyloid-β (Aβ) …

Although fasting is increasingly applied for disease prevention and treatment, consensus on terminology is lacking. Using Delphi methodology, an international, multidisciplinary panel of researchers and clinicians standardized definitions of various fasting approaches in humans. Five online surveys and a live online conference were conducted with 38 experts, 25 of whom completed all 5 surveys. Consensus was achieved for the following terms: “fasting” (voluntary abstinence from some or all foods or foods and beverages), “modified fasting” (restriction of energy intake to max. 25% of energy needs), “fluid-only fasting,” “alternate-day fasting,” “short-term fasting” (lasting 2–3 days), “prolonged fasting” (≥4 consecutive days), and …

In the wild, C. elegans are emersed in environments teeming with a veritable menagerie of microorganisms. The C. elegans cuticular surface serves as a barrier and first point of contact with their microbial environments. In this study, we identify microbes from C. elegans natural habitats that associate with its cuticle, constituting a simple “skin microbiome.” We rear our animals on a modified CeMbio, mCeMbio, a consortium of ecologically relevant microbes. We first combine standard microbiological methods with an adapted micro skin-swabbing tool to describe the skin-resident bacteria on the C. elegans surface. Furthermore, we conduct 16S rRNA gene sequencing studies …

Analysis And Tritrophic Associations Of Bats, Bat Flies, And Laboulbeniales Microfungi In Kenya, Ally Willis

Masters Theses & Specialist Projects

Bats (Chiroptera) are host to diverse lineages of ectoparasitic arthropods including ticks, mites, fleas, bat bugs, and bat flies (Arthropoda). Streblidae and Nycteribiidae are families in the dipteran superfamily Hippoboscoidea, and these hematophagous ectoparasites and their host associations are relatively well studied in the American tropics but not as well in east Africa. One of the main properties of host-parasite systems is host specificity, with some Eastern Hemisphere species (Nycteribiidae) appearing to display a lower level. The morphology of bat flies may drive (or be the result of) niche partitioning on the landscape of the host. Streblid bat flies in …

A Constructivist Grounded Theory Exploration Of Intergenerational Trauma Among Lgbtq+ Bipoc Individuals, Satveer Kler

Dissertations

Many scholars have argued that existing conceptualizations of trauma such as the Diagnostic and Statistical Manual of Mental Disorders (5th Ed.; DSM-5) conceptualization are inapplicable for individuals of marginalized communities. Individuals of marginalized communities may experience historical trauma, racial trauma, identity-related trauma, or collective trauma. Moreover, the effects of these forms of trauma may persist throughout different generations via biological transmission (e.g., epigenetics) or via interpersonal transmission (e.g., emotion socialization, cultural socialization, attachment, communication styles, behavioral socialization). The generational effects of these forms of trauma are referred to as intergenerational trauma. There has been a paucity of empirical explorations of …
