Cytokine Data For Cytokine Profile Assessment From Peruvian Pinniped (Arctocephalus Australis And Otaria Byronia) Plasma, Mykenzee Munaco, Milton Levin, Michael Adkesson, Susana Cárdenas-Alayzad, Dimitrios G. Giarikos, Amy C. Hirons

SECLER Data

Large colonies of two vulnerable, sympatric pinniped species, Peruvian fur seals (Arctocephalus australis Peruvian subpopulation; PFS) and South American sea lions (Otaria byronia; SASL), reside and reproduce in Punta San Juan, Peru (PSJ) where they are exposed to stressors such as contaminants and El Niño Southern Oscillation (ENSO) events. The use of cytokines as immune biomarkers can be indicative of an animal’s health and function by allowing for the assessment of an individual's cytokine balance as type I helper T cells (Th1) or type II helper T cells (Th2) dominant. Utilizing archived pinniped plasma samples from 2009-2019 …

Resistant Potato Starch Supplementation Reduces Serum Histamine Levels In Healthy Adults With Links To Attenuated Intestinal Permeability, Jason R. Bush, Jun Han, Edward C. Deehan, Scott V. Harding, Madhura Maiya, Joshua Baisley, David Schibli, David R. Goodlett

Department of Nutrition and Health Sciences: Faculty Publications

Histamine from our diet or gut microbes can trigger gastrointestinal disturbances, and resistant potato starch (RPS) has previously been shown to alleviate these symptoms while increasing levels of health-associated bacteria such as Akkermansia through unknown mechanisms. Post hoc exploratory metabolomic analysis of serum amino acid, amine, and carnitine metabolites in participants consuming 3.5 g/day RPS or placebo (n = 48) was performed using liquid chromatography-mass spectrometry to determine whether RPS positively influences histamine metabolism and related parameters. Histamine levels were significantly reduced by RPS treatment, but histamine-degrading enzyme products were unaffected by RPS. RPS also reduced histamine-secreting Haemophilus and Lactobacillus …

Targeting Breast Cancer: The Familiar, The Emerging, And The Uncharted Territories, Hamidreza Montazeri Aliabadi, Arthur Manda, Riya Sidgal, Co Chung

Pharmacy Faculty Articles and Research

Breast cancer became the most diagnosed cancer in the world in 2020. Chemotherapy is still the leading clinical strategy in breast cancer treatment, followed by hormone therapy (mostly used in hormone receptor-positive types). However, with our ever-expanding knowledge of signaling pathways in cancer biology, new molecular targets are identified for potential novel molecularly targeted drugs in breast cancer treatment. While this has resulted in the approval of a few molecularly targeted drugs by the FDA (including drugs targeting immune checkpoints), a wide array of signaling pathways seem to be still underexplored. Also, while combinatorial treatments have become common practice in …

The Evolving Definition Of Plant Cell Type, Sahand Amini, Jeffrey J. Doyle, Marc Libault

Department of Agronomy and Horticulture: Faculty Publications

In 1665 Robert Hooke, looking at cork through his microscope, discovered that plants are composed of elementary structures he named “cells”. Variation in the expression of a single genome in a complex eukaryotic organism guides the initiation, maturation, physiology, and biochemistry of cells with different shapes and sizes, playing different structural and functional roles in space and time. How many kinds of cells—”cell types”— an organism possesses of course depends on the organism’s cellular complexity, but the plasticity within a cell type fuels the emergence of the concept of cell state (Figure 1). The transition between cell states is driven …

A Human Stat3 Gof Variant Alters T Cell Function To Drive Skin Inflammation, Kelsey Adele Toth

Arts & Sciences Graduate Student Theses and Dissertations

Inborn errors of immunity (IEIs) are disorders caused by monogenic variants that lead to immune deficiency and dysregulation. Although rare, IEIs have shaped our understanding of how single genes function in the immune systems of both humans and mice. The identification of loss-of-function (LOF) and gain-of-function (GOF) variants in the highly conserved signal transducer and activator of transcription (STAT) family molecules have led to discoveries involving how STAT signaling affects immune cell development, differentiation, and the induction and regulation of immune responses. Germline GOF variants in STAT3 cause early-onset multi-organ autoimmunity and immune dysregulation. Patients with STAT3 GOF syndrome have …

Assessing Threats To Plant Populations: Linking Pollinator Differences To Patterns Of Plant Fitness And Population Genetics, Rieka Yu

Dissertations

Land use change is a major driver of biodiversity loss and consequently has led to the loss of genetic diversity in many plant populations due to declines in population sizes and an increase in spatial isolation. However, not all plant populations respond similarly to land-use change, suggesting there are additional mechanisms mediating plant population genetic patterns. Here, I examine the role of pollinators as this mediating factor. In Chapter 1 I conducted a meta-analysis to investigate how different types of pollinators drive changes in gene flow for plant populations in disturbed habitats, finding that different types of pollinators mediate different …

Music Advocacy: The Cognitive Development, Behavioral And Emotional Management, And Academic Success That Music Education Provides Students In Louisiana’S Low Socioeconomic Elementary Schools, Cory D. Dugar

Doctoral Dissertations and Projects

There are many technological curricular activities in math and science classrooms, yet few are found in music classrooms. Although many elementary schools may be benefiting from advocacy for music and technology, many elementary schools in the state of Louisiana have lost funding for music programs. For the Louisiana Department of Education to act as an advocate for music education, there must be a thorough understanding of the benefits of music education. Extensive research is one way to suggest that elementary music classes can raise the cognitive capacity of elementary students and could be the catalyst for ensuring the upcoming generation’s …

Temporal Organization Of Stride-To-Stride Variations Contradicts Predictive Models For Sensorimotor Control Of Footfalls During Walking, Madhur Mangalam, Damian G. Kelty-Stephen, Joel H. Sommerfeld, Nicholas Stergiou, Aaron Likens

Journal Articles

Walking exhibits stride-to-stride variations. Given ongoing perturbations, these variations critically support continuous adaptations between the goal-directed organism and its surroundings. Here, we report that stride-to-stride variations during self-paced overground walking show cascade-like intermittency—stride intervals become uneven because stride intervals of different sizes interact and do not simply balance each other. Moreover, even when synchronizing footfalls with visual cues with variable timing of presentation, asynchrony in the timings of the cue and footfall shows cascade-like intermittency. This evidence conflicts with theories about the sensorimotor control of walking, according to which internal predictive models correct asynchrony in the timings of the cue …

Seasonal Top-Down Effects Of Fish On Benthic Macroinvertebrates And Periphyton In A Coldwater Michigan Stream, Travis John Ellens

Masters Theses

Fish can have strong top-down effects on their prey through both direct predation and non-consumptive effects in streams. We conducted manipulative field experiments to test the strength of fish predation on benthic macroinvertebrates at the patch scale in Stegman Creek. Stegman Creek is a small (0.39 m³/s at baseflow), groundwater-fed stream in western Michigan with abundant mottled sculpin (Cottus bairdii) and brown trout (Salmo trutta) acting as benthic predators. We hypothesized that fish predation decreases macroinvertebrate density, thereby increasing periphyton biomass through a reduction in density of grazing macroinvertebrates. We placed paired predator-exclusion cages …

Immunotherapy Targeting Different Immune Compartments In Combination With Radiation Therapy Induces Regression Of Resistant Tumors, Nils-Petter Rudqvist, Maud Charpentier, Claire Lhuillier, Erik Wennerberg, Sheila Spada, Caroline Sheridan, Xi Kathy Zhou, Tuo Zhang, Silvia C Formenti, Jennifer S Sims, Alicia Alonso, Sandra Demaria

Faculty, Staff and Student Publications

Radiation therapy (RT) increases tumor response to CTLA-4 inhibition (CTLA4i) in mice and in some patients, yet deep responses are rare. To identify rational combinations of immunotherapy to improve responses we use models of triple negative breast cancer highly resistant to immunotherapy in female mice. We find that CTLA4i promotes the expansion of CD4+ T helper cells, whereas RT enhances T cell clonality and enriches for CD8+ T cells with an exhausted phenotype. Combination therapy decreases regulatory CD4+ T cells and increases effector memory, early activation and precursor exhausted CD8+ T cells. A combined gene signature comprising these three CD8+ …

Tito, Pandu Sulistiawan, Muhammad Khoirul, Rana Farrasati, Iput Pradiko, Patricio Grassini, Maja Slingerland

Department of Agronomy and Horticulture: Faculty Publications

CONTEXT: Smallholders are responsible for a large share of global palm oil production. Yet, in Indonesia, the main palm oil producing country, smallholders’ yields remain low. Better management practices, including short harvest interval (HI, the number of days between two harvest rounds), could help to raise smallholder yields. However, at present, HI is long in smallholder fields and the drivers underlying this phenomenon are poorly understood.

OBJECTIVE: We explored agronomic, socio-economic, and institutional factors that underlie harvesting practices in independent oil palm smallholder farming systems in Indonesia to assess scope for sustainable intensification through shorter HI and reduced …

The regulation of gene expression relies on the complex interplay of transcription factors (TFs) that interact with DNA to control gene activity. Despite extensive research efforts, accurately predicting crucial aspects of the transcriptional process, such as TF occupancy in vivo, remains a challenging task. Existing thermodynamic models of TF function often fall short in explaining experimental observations, suggesting the presence of undiscovered biological mechanisms. This dissertation aims to unravel the underlying principles governing the binding specificity of Zinc cluster TFs and is organized into two chapters. Chapter 1 offers a comprehensive overview of transcriptional regulation in yeast, highlighting current TF …

Effect Of Age At Injury On Neuroinflammatory Response, Microstructural Outcomes, And Function Following Traumatic Brain Injury, Sydney J. Oswalt Reitz

Arts & Sciences Graduate Student Theses and Dissertations

Traumatic brain injury (TBI) is a significant public health concern. Elderly individuals are more likely to be hospitalized and die from a TBI than younger victims, and experience worse outcomes along a series of clinical and functional endpoints. Studies exploring the mechanisms responsible for these outcome disparities are limited. As aging has been demonstrated to enhance baseline neuroinflammatory profile and is associated with synaptopathic neurodegenerative conditions linked to TBI, this thesis study sought to better characterize the relationship between aging-related neuroinflammation, microstructural—including synaptic—endpoints, and functional outcome following TBI. To this end, mice were subjected to diffuse and focal experimental brain …

Inter-Areal Communication In Posterior Parietal Cortex Supporting Eye-Hand And Bimanual Coordination, Jung Uk Kang

Arts & Sciences Graduate Student Theses and Dissertations

Understanding inter-areal communication is crucial for systems neuroscience. Much of the processing in the brain involves communication between different areas. Sensory areas must send information to motor areas, and motor areas must communicate with each other if different body parts are to be coordinated. For example, coordinating movements of the two arms likely requires interactions between motor areas in the two hemispheres. We therefore hypothesize that bimanual and eye-hand coordination relies on interhemispheric communication, and the most direct path for information exchange between the two hemispheres is through the corpus callosum. By reversibly blocking the callosal pathways connecting the left …

Observations Of The Association By Early-Juvenile Western Rock Lobster Panulirus Cygnus George, 1962 With Seagrass Assemblages (Decapoda: Achelata: Palinuridae), Daphne Oh, Tim J. Langlois, Michael A. Brooker, Hugo Salinas, Jason R. How, Simon De Lestang

Fisheries Research Articles

The fishery of the western rock lobster, Panulirus cygnus George, 1962, is Australia’s most valuable wild-caught single-species fishery. Recruitment in some regions of the fishery was observed to be significantly lower than expected after the 2010/2011 West Australian marine heatwave that caused extensive disturbance of dominant coastal habitats. This event generated interest in the study of the factors influencing survival and recruitment of post-larval benthic P. cygnus after settlement. The habitat associations of the highly cryptic post-settlement early-juveniles were previously unknown, with only anecdotal observations of individuals within limestone crevices in nearshore habitats. Our study used early-juveniles derived from …

Faculty, Staff and Student Publications

Identifying biomarkers for Alzheimer's disease with a goal of early detection is a fundamental problem in clinical research. Both medical imaging and genetics have contributed informative biomarkers in literature. To further improve the performance, recently, there is an increasing interest in developing analytic approaches that combine data across modalities such as imaging and genetics. However, there are limited methods in literature that are able to systematically combine high-dimensional voxel-level imaging and genetic data for accurate prediction of clinical outcomes of interest. Existing prediction models that integrate imaging and genetic features often use region level imaging summaries, and they typically do …

The Far-Reaching Effects Of Genetic Process In A Keystone Predator Species, Grey Wolves, Sarah Hoy, Philip W. Hedrick, Rolf O. Peterson, Leah Vucetich, Kristin Brzeski, John A. Vucetich

Michigan Tech Publications

Although detrimental genetic processes are known to adversely affect the viability of populations, little is known about how detrimental genetic processes in a keystone species can affect the functioning of ecosystems. Here, we assessed how changes in the genetic characteristics of a keystone predator, grey wolves, affected the ecosystem of Isle Royale National Park over two decades. Changes in the genetic characteristic of the wolf population associated with a genetic rescue event, followed by high levels of inbreeding, led to a rise and then fall in predation rates on moose, the primary prey of wolves and dominant mammalian herbivore in …
