Subcutaneous phaeohyphomycosis typically affects immunocompetent individuals following traumatic inoculation. Severe or disseminated infection can occur in CARD9 deficiency or after transplantation, but the mechanisms protecting against phaeohyphomycosis remain unclear. We evaluated a patient with progressive, refractory Corynespora cassiicola phaeohyphomycosis and found that he carried biallelic deleterious mutations in CLEC7A encoding the CARD9-coupled, β-glucan-binding receptor, Dectin-1. The patient's PBMCs failed to produce TNF-α and IL-1β in response to β-glucan and/or C. cassiicola. To confirm the cellular and molecular requirements for immunity against C. cassiicola, we developed a mouse model of this infection. Mouse macrophages required Dectin-1 and CARD9 for IL-1β and …

Department of Pediatrics Faculty Papers

The mucopolysaccharidoses (MPS), Pompe Disease (PD), and Krabbe disease (KD) are inherited conditions known as lysosomal storage disorders (LSDs) The resulting enzyme deficiencies give rise to progressive symptoms. The United States Department of Health and Human Services' Recommended Uniform Screening Panel (RUSP) suggests LSDs for inclusion in state universal newborn screening (NBS) programs and has identified screening deficiencies in MPS I, KD, and PD NBS programs. MPS I NBS programs utilize newborn dried blood spots and assay alpha L-iduronidase (IDUA) enzyme to screen for potential cases. Glycosaminoglycans (GAGs) offer potential as a confirmatory test. KD NBS programs utilize galactocerebrosidase (GaLC) …

Peninsula Medical School

Background Psychological stress has an established bi-directional relationship with obesity. Mindfulness techniques reduce stress and improve eating behaviours, but their long-term impact remains untested. CALMPOD (Compassionate Approach to Living Mindfully for Prevention of Disease) is a psychoeducational mindfulness-based course evidenced to improve eating patterns across a 6-month period, possibly by reducing stress. However, no long-term evaluation of impact exists. Aims This study retrospectively evaluates 2-year outcomes of CALMPOD on patient engagement, weight and metabolic markers. Method All adults with a body mass index >35 kg/m2 attending an UK obesity service during 2016-2020 were offered CALMPOD. Those who refused CALMPOD were …

Policy Considerations That Support Equitable Access To Responsible, Accountable, Safe, And Ethical Uses Of Psychedelic Medicines, Sean J Belouin, Lynnette A Averill, Jack E Henningfield, Stephen N Xenakis, Ingrid Donato, Charles S Grob, Ann Berger, Veronica Magar, Alicia L Danforth, Brian T Anderson

Faculty, Staff and Students Publications

There is mounting evidence suggesting psychedelic and entactogen medicines (namely psilocybin and 3,4-methylenedioxymethamphetamine [MDMA]), in conjunction with proper psychosocial support, hold the potential to provide safe, rapid acting, and robust clinical improvements with durable effects. In the US, both psilocybin and MDMA have been granted Breakthrough Therapy designations by the US Food and Drug Administration and may potentially receive full FDA approval with similar regulatory considerations occurring in multiple countries. At the same time, regulatory changes are poised to increase access to legal or decriminalized psychedelic use in various non-medical settings. This review provides a brief discussion on the historical …

A, B, C'S Of Trk Receptors And Their Ligands In Ocular Repair, Akash Gupta, Jeremias G Galletti, Zhiyuan Yu, Kevin Burgess, Cintia S De Paiva

Faculty, Staff and Students Publications

Neurotrophins are a family of closely related secreted proteins that promote differentiation, development, and survival of neurons, which include nerve growth factor (NGF), brain-derived neurotrophic factor, neurotrophin-3, and neurotrophin-4. All neurotrophins signal through tropomyosin receptor kinases (TrkA, TrkB, and TrkC) which are more selective to NGF, brain-derived neurotrophic factor, and neurotrophin-3, respectively. NGF is the most studied neurotrophin in the ocular surface and a human recombinant NGF has reached clinics, having been approved to treat neurotrophic keratitis. Brain-derived neurotrophic factor, neurotrophin-3, and neurotrophin-4 are less studied neurotrophins in the ocular surface, even though brain-derived neurotrophic factor is well characterized in …

Rationale: Obstructive sleep apnea (OSA) is a common disorder associated with increased risk for cardiovascular disease, diabetes, and premature mortality. There is strong clinical and epidemiologic evidence supporting the importance of genetic factors influencing OSA but limited data implicating specific genes.

Objectives: To search for rare variants contributing to OSA severity.

Methods: Leveraging high-depth genomic sequencing data from the NHLBI Trans-Omics for Precision Medicine (TOPMed) program and imputed genotype data from multiple population-based studies, we performed linkage analysis in the CFS (Cleveland Family Study), followed by multistage gene-based association analyses in independent cohorts for apnea-hypopnea index (AHI) in a total …

Secure Cloud-Based Iot Water Quality Gathering For Analysis And Visualization, Soin Abdoul Kassif Baba M Traore, Maria Valero, Amy Gruss

KSU Proceedings on Cybersecurity Education, Research and Practice

Water quality refers to measurable water characteristics, including chemical, biological, physical, and radiological characteristics usually relative to human needs. Dumping waste and untreated sewage is the reason for water pollution and several diseases to the living hood. The quality of water can also have a significant impact on animals and plant ecosystems. Therefore, keeping track of water quality is a substantial national interest. Much research has been done for measuring water quality using sensors to prevent water pollution. In summary, those systems are built based on online and reagent-free water monitoring SCADA systems in wired networks. However, centralized servers, transmission …

The Conquest Of Milk: The Rise Of Lactase Persistence And The Fall Of Scandinavian Hunter-Gatherers, Nicholas Mays

James Madison Undergraduate Research Journal (JMURJ)

Over half of the global human population suffers from lactase nonpersistence, a condition marked by losing the ability to digest lactose after infancy. However, a minority of the global population, primarily located in Central and Northern Europe, has a genetic mutation that results in lactase persistence, which is the continued ability to process lactose after infancy. This interdisciplinary analysis blends archaeology, cultural anthropology, evolutionary biology, and archaeogenetics to explore the origin and rise of lactase persistence in Europe and its contribution to the end of hunter-gatherer societies in Scandinavia. Furthermore, the paper uses gene-culture coevolutionary theory to argue that lactase …

“…And I Thought That Was A Queer Thing To Do”: Transmasculine Identity In The Lokasenna, Tevye J. Schmidt

The Confluence

This paper seeks to explain the viewing of Loki through a lens of transmasculine identity, focusing on the ways in which gender expression and identity were viewed in Scandinavia during the Middle Ages. The current scholarship on Loki and gender expression, specifically in his interactions with the other gods in the Lokasenna, suggests a reading that is misogynistic on Loki’s part. This reading and translation also suggest homophobia and transphobia from Odin. This paper argues that these translations lack the nuance that a reading of Loki as transmasculine brings, and that this reading is important in breaking down modern …

The Nitrogen Dynamics Of Deer Cave, Sarawak, And The Role Of Bat Caves As Biogeochemical Sinks In Tropical Moist Forests., Joyce Lundberg, Donald A. Mcfarlane, Guy Van Rentergem

International Journal of Speleology

A better understanding of the role of bat caves as nitrogen sinks in tropical moist forest ecosystems can be expected to shed light on regional and spatial variability in nutrient recycling studies. We measured the nitrogen flux (in air and water) associated with a very large Chaerephon plicata bat colony in Deer Cave, Borneo, in the process generating a new, quantitative, estimate of the total bat population (774,828 ±48,320), and the first detailed modelling of an ammonia plume in a cave. Long-term storage of N does not occur in this wet cave. Our final budget numbers indicate that, of the …

St-Segment Elevation Myocardial Infarction In North African Women: Results From A Twenty-Year Experience., Ikram Chamtouri, Rania Souissi, Nesrine Amdouni, Walid Jomaa, Wajih Abdallah, Khaldoun Ben Hamda, Faouzi Maatouk

Journal of the Saudi Heart Association

Background. Coronary artery disease remains the most common cause of morbidity and mortality in the general population. Several studies in developed countries have reported a gender-related difference in ST-segment elevation myocardial infarction (STEMI) in terms of risk factors, clinical presentation, delays in management, therapeutic modalities, and in-hospital as well as one-year outcomes. Data from non-developed countries about women with STEMI remain rare. We therefore aimed through this study to investigate the baseline characteristics of STEMI in Tunisian women compared to men and to determine the impact of gender difference on STEMI complications, in-hospital mortality, and one-year follow-up outcomes. Methods. All …

Digitally Predicting Protein Localization And Manipulating Protein Activity In Fluorescence Images Using 4d Reslicing Gan, Yang Jiao, Lingkun Gu, Yingtao Jiang, Mo Weng, Mei Yang

Electrical & Computer Engineering Faculty Research

While multi-channel fluorescence microscopy is a vital imaging method in biological studies, the number of channels that can be imaged simultaneously is limited by technical and hardware limitations such as emission spectra cross-talk. One solution is using deep neural networks to model the localization relationship between two proteins so that the localization of one protein can be digitally predicted. Furthermore, the input and predicted localization implicitly reflect the modeled relationship. Accordingly, observing the response of the prediction via manipulating input localization could provide an informative way to analyze the modeled relationships between the input and the predicted proteins.

Statistical Methods For Differential Gene Expression Analysis Under The Case-Cohort Design, Lidong Wang

Mathematics & Statistics ETDs

Differential gene expression analysis has the potential to discover candidate biomarkers, therapeutic targets, and gene signatures. How to save money when using an unaffordable sample is a practical question. The case-cohort (CCH) study design can blend the economy of case-control studies with the advantages of cohort studies. But it has not been seen in the medical research literature where high-throughput genomic data were involved.

A score test does not need to fit the Cox PH model iteratively; hence, it can save computing time and avoid potential convergence issues. We developed a score test under the CCH design to identify DEGs …

Evaluating Microneedle Impedance For Monitoring Water Potential In Vitis Vinifera And Helianthus Annuus, Erica Grace Pauer

Biology ETDs

Measurements of plant water potential provide fundamental insights into how plants are interacting with the environment to manage water needs. However, monitoring water potential is difficult, time consuming, and frequently destructive. Several methods have been in development that attempt to monitor the water status of plant tissues in a simple, continuous, and non-destructive manner. One of these methods, electrical impedance spectroscopy (EIS), is emerging as a particularly promising tool that has several applications in plant biology. I used a new microneedle system that applies small electrodes to a range of tissues. By utilizing this tool in conjunction with a standard …

Functional Links Between Thermoregulation And Sleep In Children With Neurodevelopmental And Chronic Health Conditions, Susan M. Mccabe, Chris R. Abbiss, Jean Pierre Libert, Véronique Bach

Research outputs 2022 to 2026

The bi-directional relationship between sleep and wake is recognized as important for all children. It is particularly consequential for children who have neurodevelopmental disorders (NDDs) or health conditions which challenge their sleep and biological rhythms, and their ability to maintain rhythms of participation in everyday activities. There are many studies which report the diverse reasons for disruption to sleep in these populations. Predominantly, there is focus on respiratory, pharmaceutical, and behavioral approaches to management. There is, however, little exploration and explanation of the important effects of body thermoregulation on children’s sleep-wake patterns, and associated behaviors. Circadian patterns of sleep-wake are …

A Pooling Strategy For Detecting Carbapenem Resistance Genes By The Xpert Carba-R Test In Rectal Swab Specimens, Fred C. Tenover, Peng Zhang, Qi Wang, Chaoe Zhou, Feifei Zhang, Xinghui Gao, Yi-Wei Tang, Hui Wang

Biology Faculty Publications

Rapid and accurate detection of carriers of carbapenemase-producing organisms (CPO) in hospitalized patients is critical for infection control and prevention. This study aimed to evaluate a pooling strategy for the detection of carbapenem resistance genes (CRG) in multiple specimens using the Xpert Carba-R test. Two rectal swabs each were collected from 415 unique patients. One swab was tested by Carba-R on the five specimen-pooled strategy. The other swab was tested individually by culture followed by DNA sequence analysis for CRG as the reference. At the first 5:1 pooling testing, 22 of 83 pools were positive, which yielded 34 positives from …

Extracellular Dnases Facilitate Antagonism And Coexistence In Bacterial Competitor-Sensing Interference Competition, Aoi Ogawa, Christophe Golé, Maria Bermudez, Odrine Habarugira, Gabrielle Joslin, Taylor Mccain, Autumn Mineo, Jennifer Wise, Julie Xiong, Katherine Yan, Jan A.C. Vriezen

Biological Sciences: Faculty Publications

Over the last 4 decades, the rate of discovery of novel antibiotics has decreased drastically, ending the era of fortuitous antibiotic discovery. A better understanding of the biology of bacteriogenic toxins potentially helps to prospect for new antibiotics. To initiate this line of research, we quantified antagonists from two different sites at two different depths of soil and found the relative number of antagonists to correlate with the bacterial load and carbon-to-nitrogen (C/N) ratio of the soil. Consecutive studies show the importance of antagonist interactions between soil isolates and the lack of a predicted role for nutrient availability and, therefore, …

Thanatechnology: Designing For Death, Samantha Grace Bruner

Theses and Dissertations

Thanatechnology, or the study of death technology, is based within the human need to “figure out” death. Through the ages, humans have used technology to further our understanding of what it means to die and what it means to mourn as a way of figuring out what it means to live. Digital data is a huge part of recent digital technology and includes social media data which is a part of many peoples’ daily lives. This leads to many questions including what happens to social media pages when someone dies. These “digital graveyards” leave a lasting impact on many social …

Molecular Subclasses Of Clear Cell Ovarian Carcinoma And Their Impact On Disease Behavior And Outcomes, Kelly L Bolton, Irenaeus C C Chan, Brian J Wiley, Et Al.

2020-Current year OA Pubs

PURPOSE: To identify molecular subclasses of clear cell ovarian carcinoma (CCOC) and assess their impact on clinical presentation and outcomes.

EXPERIMENTAL DESIGN: We profiled 421 primary CCOCs that passed quality control using a targeted deep sequencing panel of 163 putative CCOC driver genes and whole transcriptome sequencing of 211 of these tumors. Molecularly defined subgroups were identified and tested for association with clinical characteristics and overall survival.

RESULTS: We detected a putative somatic driver mutation in at least one candidate gene in 95% (401/421) of CCOC tumors including ARID1A (in 49% of tumors), PIK3CA (49%), TERT (20%), and TP53 (16%). …

Using Stable Isotope Analyses To Assess The Trophic Ecology Of Scleractinian Corals, Michael P. Lesser, Marc Slattery, Keir J. Macartney

School of Earth, Environmental, & Marine Sciences Faculty Publications

Studies on the trophic ecology of scleractinian corals often include stable isotope analyses of tissue and symbiont carbon and nitrogen. These approaches have provided critical insights into the trophic sources and sinks that are essential to understanding larger-scale carbon and nitrogen budgets on coral reefs. While stable isotopes have identified most shallow water (<30 m) corals as mixotrophic, with variable dependencies on autotrophic versus heterotrophic resources, corals in the mesophotic zone (~30–150 m) transition to heterotrophy with increasing depth because of decreased photosynthetic productivity. Recently, these interpretations of the stable isotope data to distinguish between autotrophy and heterotrophy have been criticized because they are confounded by increased nutrients, reverse translocation of photosynthate, and changes in irradiance that do not influence photosynthate translocation. Here we critically examine the studies that support these criticisms and show that they are contextually not relevant to interpreting the transition to heterotrophy in corals from shallow to mesophotic depths. Additionally, new data and a re-analysis of previously published data show that additional information (e.g., skeletal isotopic analysis) improves the interpretation of bulk stable isotope data in determining when a transition from primary dependence on autotrophy to heterotrophy occurs in scleractinian corals.
