Community Ecology And Disease Dynamics In Pacific Oysters: Unraveling Microbiome-Pathogen Interactions In The Wild, Victoria E. Cifelli

Cal Poly Humboldt theses and projects

In the context of multispecies microbial assemblages, disruptions can occur when there are alterations in host conditions, such as the onset of a disease. Notably, viruses have the potential to reshape a host's microbial community. However, the role of the host's habitat and environment, which could be pivotal in communities with shifting niche space and habitat filters, is often overlooked in host-microbe-pathogen interactions. Recognizing the importance of these factors, I employed a field-based approach to understand microbial community dynamics in the presence of disease. To address the influence of geographical location, I conducted an analysis involving healthy and infected oysters …

Writing Outside The Soviet Canon: Aleksandr Kozachinskii's "The Green Wagon" As Roman A Clef And Odesa Memoir, Cassio F. De Oliveira

World Languages and Literatures Faculty Publications and Presentations

This essay analyzes Aleksandr Kozachinskii’s 1938 Russian-language novella “The Green Wagon” as a roman à clef and exemplar of the Odesa Myth that has been unjustly neglected in literary scholarship. Reasons for the neglect of “The Green Wagon” include the historical context of its publication, between the Great Purges of 1936–1938 and the outbreak of World War II; Kozachinskii’s untimely death; and the conventional interpretation of the novella that reduces it to a fictionalized account of Kozachinskii’s friendship with Evgenii Petrov in Odesa during the early Soviet period. Against such a reductionist reading, and on the basis of recent archival-based …

Implications Of Physical Fault Injections On Single Chip Motes, Sara Faour, Mališa Vučinić, Filip Maksimovic, David Burnett, Paul Muhlethaler, Thomas Watteyne, Kristofer Pister

Electrical and Computer Engineering Faculty Publications and Presentations

Single-chip motes are wireless sensor nodes that integrate computation, communication, power and sensing on a single chip. We consider the security threats these novel devices are subject to when employed in safety-critical applications. Fault injection attacks are a prominent form of physical attacks that pose a threat to the normal and secure functioning of targeted devices, potentially compromising their intended behavior. These attacks have been studied mainly on commercial off-the-shelf devices which rely on external components such as crystal oscillators and passives. Such external components are absent from single-chip motes, resulting in a uniquely different attack surface compared to commercial …

Transformations Between Rotational And Translational Invariants Formulated In Reciprocal Spaces, Philip R Baldwin

Faculty, Staff and Students Publications

Correlation functions play an important role in the theoretical underpinnings of many disparate areas of the physical sciences: in particular, scattering theory. More recently, they have become useful in the classification of objects in areas such as computer vision and our area of cryoEM. Our primary classification scheme in the cryoEM image processing system, EMAN2, is now based on third order invariants formulated in Fourier space. This allows a factor of 8 speed up in the two classification procedures inherent in our software pipeline, because it allows for classification without the need for computationally costly alignment procedures. In this work, …

The Neurobiology Of Duration Of Untreated Psychosis: A Comprehensive Review, Anthony W Zoghbi, Jeffrey A Lieberman, Ragy R Girgis

Faculty, Staff and Students Publications

Duration of untreated psychosis (DUP) is defined as the time from the onset of psychotic symptoms until the first treatment. Studies have shown that longer DUP is associated with poorer response rates to antipsychotic medications and impaired cognition, yet the neurobiologic correlates of DUP are poorly understood. Moreover, it has been hypothesized that untreated psychosis may be neurotoxic. Here, we conducted a comprehensive review of studies that have examined the neurobiology of DUP. Specifically, we included studies that evaluated DUP using a range of neurobiologic and imaging techniques and identified 83 articles that met inclusion and exclusion criteria. Overall, 27 …

The Pathway To The Natural Gas Industry: Financial Development, Coal Consumption, And Carbon Dioxide Emissions In Pr China, Teng Tong, Jaime Ortiz, Haibo Wang

Faculty, Staff and Students Publications

This paper revisits the causal links between financial development, coal consumption, and CO2 emissions in P.R. China over the 1977–2017 period to validate the development of its natural gas industry. It uses a Bootstrap ARDL bound test with structural breaks to establish stationarity, short- and long-run dynamics, and causality of the series. The results show there are no long-run relationships among these three variables, but a Granger causality test does indicate the presence of both a two-way Granger causality between coal consumption and CO2 emissions, and a one-way Granger causality running from financial development to both coal consumption and CO2 …

The Tmem106b T186s Coding Variant Increases Neurite Arborization And Synaptic Density In Primary Hippocampal Neurons, Quynh Nguyen, Caleb A Wood, Peter J Kim, Joanna L Jankowsky

Faculty, Staff and Students Publications

The lysosomal protein TMEM106B was identified as a risk modifier of multiple dementias including frontotemporal dementia and Alzheimer’s disease. The gene comes in two major haplotypes, one associated with disease risk, and by comparison, the other with resilience. Only one coding polymorphism distinguishes the two alleles, a threonine-to-serine substitution at residue 185 (186 in mouse), that is inherited in disequilibrium with multiple non-coding variants. Transcriptional studies suggest synaptic, neuronal, and cognitive preservation in human subjects with the protective haplotype, while murine in vitro studies reveal dramatic effects of TMEM106B deletion on neuronal development. Despite this foundation, the field has not …

Framework For Accurate Classification Of Self-Reported Stress From Multisession Functional Mri Data Of Veterans With Posttraumatic Stress, Rahul Goel, Teresa Tse, Lia J Smith, Andrew Floren, Bruce Naylor, M Wright Williams, Ramiro Salas, Albert S Rizzo, David Ress

Faculty, Staff and Students Publications

Background: Posttraumatic stress disorder (PTSD) is a significant burden among combat Veterans returning from the wars in Iraq and Afghanistan. While empirically supported treatments have demonstrated reductions in PTSD symptomatology, there remains a need to improve treatment effectiveness. Functional magnetic resonance imaging (fMRI) neurofeedback has emerged as a possible treatment to ameliorate PTSD symptom severity. Virtual reality (VR) approaches have also shown promise in increasing treatment compliance and outcomes. To facilitate fMRI neurofeedback-associated therapies, it would be advantageous to accurately classify internal brain stress levels while Veterans are exposed to trauma-associated VR imagery. Methods: Across 2 sessions, we used fMRI …

Climate Change As A Social Determinant Of Health: An Interactive Case-Based Learning Activity, Arindam Sarkar, Nital P Appelbaum, Rathi Asaithambi, Connie Tran, Doris Lin, Anjali Aggarwal, Stephanie Nguyen

Faculty, Staff and Students Publications

INTRODUCTION: Despite consensus on climate change's impact on humans, medical schools have not widely adopted inclusion of environmental topics into their mandatory curriculum. This educational activity explicitly addresses climate change as one of the environmental determinants of health (EDH).

METHODS: We developed a required, 1-hour module for all first-year medical students. This interactive, case-based, small-group activity was incorporated into a curriculum within an advising program but could be run independently. Before and after the session, participants completed evaluations assessing knowledge gains and attitude shifts.

RESULTS: Of 183 first-year students, 155 completed both pre- and postmodule surveys. Participants' rating increased on …

Adeno-Associated Virus 8 Delivers An Immunomodulatory Peptide To Mouse Liver More Efficiently Than To Rat Liver, Yuqing Wang, Ayrea Hurley, Marco De Giorgi, Mark R Tanner, Rong-Chi Hu, Michael W Pennington, William R Lagor, Christine Beeton

Faculty, Staff and Students Publications

Targeting the Kv1.3 potassium channel has proven effective in reducing obesity and the severity of animal models of autoimmune disease. Stichodactyla toxin (ShK), isolated from the sea anemone Stichodactyla helianthus, is a potent blocker of Kv1.3. Several of its analogs are some of the most potent and selective blockers of this channel. However, like most biologics, ShK and its analogs require injections for their delivery, and repeated injections reduce patient compliance during the treatment of chronic diseases. We hypothesized that inducing the expression of an ShK analog by hepatocytes would remove the requirement for frequent injections and lead to a …

Faculty, Staff and Students Publications

BACKGROUND: Cell therapies for solid tumors are thwarted by the hostile tumor microenvironment (TME) and by heterogeneous expression of tumor target antigens. We address both limitations with a novel class of chimeric antigen receptors based on plant lectins, which recognize the aberrant sugar residues that are a 'hallmark' of both malignant and associated stromal cells. We have expressed in T cells a modified lectin from banana, H84T BanLec, attached to a chimeric antigen receptor (H84T-CAR) that recognizes high-mannose (asparagine residue with five to nine mannoses). Here, we tested the efficacy of our novel H84T CAR in models of pancreatic ductal …

Structural Basis Of Ferroportin Inhibition By Minihepcidin Pr73, Azaan Saalim Wilbon, Jiemin Shen, Piotr Ruchala, Ming Zhou, Yaping Pan

Faculty, Staff and Students Publications

Ferroportin (Fpn) is the only known iron exporter in humans and is essential for maintaining iron homeostasis. Fpn activity is suppressed by hepcidin, an endogenous peptide hormone, which inhibits iron export and promotes endocytosis of Fpn. Hepcidin deficiency leads to hemochromatosis and iron-loading anemia. Previous studies have shown that small peptides that mimic the first few residues of hepcidin, i.e., minihepcidins, are more potent than hepcidin. However, the mechanism of enhanced inhibition by minihepcidins remains unclear. Here, we report the structure of human ferroportin in complex with a minihepcidin, PR73 that mimics the first 9 residues of hepcidin, at 2.7 …

Quantitative Measurement Of Protac Intracellular Accumulation, Xin Yu, Jin Wang

Faculty, Staff and Students Publications

In recent years, Proteolysis Targeting Chimera (PROTAC) technology has emerged as one of the most promising approaches to remove disease-associated proteins by utilizing cells' own destruction machinery. To achieve successful degradation of a protein of interest (POI), the heterobifunctional PROTAC molecules must penetrate into the cells first, followed by target engagement and formation of the POI-PROTAC-E3 ligase complex. Based on this understanding, the assessment of cell permeability and in cell target engagement are of great importance to evaluate the efficacy of PROTAC candidates. PROTAC molecules can be classified as non-covalent and covalent, and covalent PROTACs can be further divided into …

Faculty, Staff and Students Publications

A 70-year-old veteran with prior triple vessel coronary artery bypass grafting (CABG) presented with exertional chest pain. His work-up revealed > 40 mm Hg bilateral upper extremity blood pressure difference. Chest computed tomography and invasive angiography revealed severe stenosis at the ostium of the left subclavian artery, proximal to the origin of the left internal mammary artery to left anterior descending artery graft (LIMA-LAD). A diagnosis of coronary subclavian steal syndrome (CSSS) was made, and carotid-subclavian bypass was performed. This case outlines when to suspect CSSS, an approach to its diagnosis, and the importance of its timely management.

Review Of Acute Kidney Injury And Progression To Chronic Kidney Disease In Pediatric Patients Undergoing Hematopoietic Cell Transplant, Kim T Vuong, Catherine Joseph, Joseph R Angelo

Faculty, Staff and Students Publications

While acute kidney injury (AKI) after hematopoietic cell transplant (HCT) has been well-described in pediatric patients, literature regarding the long term renal consequences of HCT-related AKI, the development of chronic kidney disease (CKD), and CKD care in pediatric patients post-HCT is limited. CKD affects almost 50% of patients after HCT with multifactorial etiology including infection, nephrotoxic medications, transplant-associated thrombotic microangiopathy, graft-versus-host disease, and sinusoidal obstruction syndrome. As renal function declines in CKD, eventually progressing to end stage kidney disease (ESKD), mortality increases and is more than 80% among patients requiring dialysis. Using society guidelines and current literature, this review summarizes …

Mass Spectrometry Imaging As An Emerging Tool For Studying Metabolism In Human Brain Organoids, Gerarda Cappuccio, Saleh M Khalil, Sivan Osenberg, Feng Li, Mirjana Maletic-Savatic

Faculty, Staff and Students Publications

Human brain organoids are emerging models to study human brain development and pathology as they recapitulate the development and characteristics of major neural cell types, and enable manipulation through an in vitro system. Over the past decade, with the advent of spatial technologies, mass spectrometry imaging (MSI) has become a prominent tool for metabolic microscopy, providing label-free, non-targeted molecular and spatial distribution information of the metabolites within tissue, including lipids. This technology has never been used for studies of brain organoids and here, we set out to develop a standardized protocol for preparation and mass spectrometry imaging of human brain …

Pre-Treatment Inflamed Tumor Immune Microenvironment Is Associated With Folfirinox Response In Pancreatic Cancer, Zachary Gao, Sung Wook Kang, Derek Erstad, Joseph Azar, George Van Buren, William Fisher, Zequn Sun, Mark P Rubinstein, Hyun-Sung Lee, E Ramsay Camp

Faculty, Staff and Students Publications

INTRODUCTION: Pancreatic adenocarcinoma (PDAC) is an aggressive tumor with limited response to both chemotherapy and immunotherapy. Pre-treatment tumor features within the tumor immune microenvironment (TiME) may influence treatment response. We hypothesized that the pre-treatment TiME composition differs between metastatic and primary lesions and would be associated with response to modified FOLFIRINOX (mFFX) or gemcitabine-based (Gem-based) therapy.

METHODS: Using RNAseq data from a cohort of treatment-naïve, advanced PDAC patients in the COMPASS trial, differential gene expression analysis of key immunomodulatory genes in were analyzed based on multiple parameters including tumor site, response to mFFX, and response to Gem-based treatment. The relative …

INTRODUCTION: Preterm infants have increased risk of impaired neurodevelopment to which reduced systemic levels of insulin-like growth factor 1 (IGF-1) in the weeks after birth may play a role. Hence, we hypothesized that postnatal IGF-1 supplementation would improve brain development in preterm pigs, used as a model for preterm infants.

METHODS: Preterm pigs delivered by cesarean section received recombinant human IGF-1/IGF binding protein-3 complex (rhIGF-1/rhIGFBP-3, 2.25 mg/kg/day) or vehicle from birth to postnatal day 19. Motor function and cognition were assessed by monitoring of in-cage and open field activities, balance beam test, gait parameters, novel object recognition and operant conditioning …
