Targeting Calcium-Mediated Inter-Organellar Crosstalk In Cardiac Diseases, Mohit M Hulsurkar, Satadru K Lahiri, Jason Karch, Meng C Wang, Xander H T Wehrens

Faculty, Staff and Students Publications

INTRODUCTION: Abnormal calcium signaling between organelles such as the sarcoplasmic reticulum (SR), mitochondria and lysosomes is a key feature of heart diseases. Calcium serves as a secondary messenger mediating inter-organellar crosstalk, essential for maintaining the cardiomyocyte function.

AREAS COVERED: This article examines the available literature related to calcium channels and transporters involved in inter-organellar calcium signaling. The SR calcium-release channels ryanodine receptor type-2 (RyR2) and inositol 1,4,5-trisphosphate receptor (IP

EXPERT OPINION: Enhanced SR calcium release via RyR2 and reduced SR reuptake via SERCA2a, increased VDAC and MCUC-mediated calcium uptake into mitochondria, and enhanced lysosomal calcium-release via lysosomal TPC and TRPML …

Prevalence And Predictors Of Missed Dysplasia On Index Barrett's Esophagus Diagnosing Endoscopy In A Veteran Population, Theresa H Nguyen, Aaron P Thrift, Rollin George, Daniel G Rosen, Hashem B El-Serag, Gyanprakash A Ketwaroo

Faculty, Staff and Students Publications

BACKGROUND & AIMS: Limitations of endoscopic sampling may result in missed dysplasia at the diagnosis of Barrett's esophagus (BE). However, the role of close follow-up endoscopy is unclear. The aim was to evaluate the proportion of patients diagnosed with "missed" dysplasia within 18 months of their index nondysplastic BE (NDBE) diagnosis.

METHODS: This was a retrospective analysis of a cohort of BE patients diagnosed during 1990-2019 at the Houston VA. Patients with BE on index esophagogastroduodenoscopy (EGD) were classified as NDBE, indefinite dysplasia, or dysplastic (low- or high-grade dysplasia) based on initial biopsies. We identified NDBE patients who had follow-up …

Intestinal Deletion Of 3-Hydroxy-3-Methylglutaryl-Coenzyme A Reductase Promotes Expansion Of The Resident Stem Cell Compartment, Alexandria M Doerfler, Jun Han, Kelsey E Jarrett, Li Tang, Antrix Jain, Alexander Saltzman, Marco De Giorgi, Marcel Chuecos, Ayrea E Hurley, Ang Li, Pauline Morand, Claudia Ayala, David R Goodlett, Anna Malovannaya, James F Martin, Thomas Q De Aguiar Vallim, Noah Shroyer, William R Lagor

BACKGROUND: The intestine occupies the critical interface between cholesterol absorption and excretion. Surprisingly little is known about the role of de novo cholesterol synthesis in this organ, and its relationship to whole body cholesterol homeostasis. Here, we investigate the physiological importance of this pathway through genetic deletion of the rate-limiting enzyme.

METHODS: Mice lacking 3-hydroxy-3-methylglutaryl-coenzyme A reductase (Hmgcr) in intestinal villus and crypt epithelial cells were generated using a Villin-Cre transgene. Plasma lipids, intestinal morphology, mevalonate pathway metabolites, and gene expression were analyzed.

RESULTS: Mice with intestine-specific loss of Hmgcr were markedly smaller at birth, but gain …

Faculty, Staff and Students Publications

The objective of this study was to investigate changes in physical activity patterns associated with the COVID-19 pandemic in individuals with overweight and obesity who were participating in a school district worksite weight loss program. We conducted comparative design interrupted time series analyses on physical activity device (Fitbit) data from the 2018-2019 and 2019-2020 school years (N = 211). We administered a questionnaire in 2020 to supplement device data. After the stay-at-home orders in 2020, participants tended to decrease their weekly step count (B = -1315.7, SE = 627.7, p = .045), decrease their weekly "Lightly active minutes" (B = …

Does Teaching About Evolution In Adventist Schools Destroy Faith In God?, Russ Butler, Stan Dobias

Andrews University Teaching and Learning Conference

Students crave an environment where questions are welcomed and where all theories are thoroughly explored. There seems to be a hesitancy to review theories that may be opposed to one’s belief. The common approach is to focus only on what Scripture teaches and then to focus exclusively on the weaknesses of a theory like evolution. The challenge is that when students do discover arguments for evolution, they may conclude that their education was incomplete, some abandon their faith. The surprising results of a 3-year study found that a thorough study of evolution does not destroy faith in God.

Bistability And Switching Behavior In Moving Animal Groups, Daniel Strömbom, Stephanie Nickerson, Catherine Futterman, Alyssa Difazio, Cameron Costello, Kolbjørn Tunstrøm

Northeast Journal of Complex Systems (NEJCS)

Moving animal groups such as schools of fish and flocks of birds frequently switch between different group structures. Standard models of collective motion have been used successfully to explain how stable groups form via local interactions between individuals, but they are typically unable to produce groups that exhibit spontaneous switching. We are only aware of one model, constructed for barred flagtail fish that are known to rely on alignment and attraction to organize their collective motion, that has been shown to generate this type of behavior in 2D (or 3D). Interestingly, another species of fish, golden shiners, do exhibit switching …

Time is a fundamental component of ecological processes. How animal behavior changes over time has been explored through well-known ecological theories like niche partitioning and predator–prey dynamics. Yet, changes in animal behavior within the shorter 24-hr light–dark cycle have largely gone unstudied. Understanding if an animal can adjust their temporal activity to mitigate or adapt to environmental change has become a recent topic of discussion and is important for effective wildlife management and conservation. While spatial habitat is a fundamental consideration in wildlife management and conservation, temporal habitat is often ignored. We formulated a temporal resource selection model to quantify …

Origin And Epigenetic Regulation Of Cutaneous T Cell Lymphoma, Carly M. Harro

USF Tampa Graduate Theses and Dissertations

The pathogenesis of Cutaneous T cell lymphoma (CTCL) remains unclear. Using conditional knockout mice, we found that ablation of the genomic organizer Special AT-rich sequence-binding protein-1 (Satb1) caused malignant transformation of mature, skin-homing, Notch-activated CD4+ and CD8+ T cells into progressively fatal lymphoma. Mechanistically, Satb1 restrained Stat5 phosphorylation and the expression of skin-homing chemokine receptors in mature T cells. H3K27 and H3K9 trimethylation occluded the SATB1 promoter in Sézary cells, while inhibition of SUV39H1/2 methyltransferases (unlike EZH2 inhibition), restored protective SATB1 expression and selectively abrogated the growth of primary Sézary cells more effectively than romidepsin. Additionally, using single-cell RNA/TCR sequencing …

Tanzania Journal of Science

The basic operating principle of photovoltaic (PV) devices is the conversion of solar irradiation into electricity. There are various applications of this principle in many countries such as Egypt, Nigeria and Denmark. Most of the solar PV projects are designed for street lighting, water pumping and water desalination. However, we hope about wide range of using the appropriate components and best technical procedures, standard PV projects with maximum performance output. The present systems now provide 20% to 40% only of the community's heat or lightness on annual basic needs. These include innovative and alternative ways to reduce material uses and …

Alzheimer's And Patient Caregiver Burnout: A Review Of The Literature, Madeline Hekeler

James Madison Undergraduate Research Journal (JMURJ)

The term “silent epidemic” is fitting for Alzheimer’s disease (AD), as its negative impact is widely felt but rarely discussed. Burnout among AD caregivers has become an epidemic of its own as caregivers experience an increase in health risks, stress, and financial burden. This literature review focuses on caregiver burnout and how imperative it is that caregivers are better supported in their role. Researchers have developed instruments to assess and intervene in caregiver burnout that have shown effectiveness among caregivers and their families.Nevertheless, further longitudinal research is warranted regarding more effective interventions, including stress management and social support mechanisms.

Diel Activity Patterns Of Two Distinct Populations Of Aedes Aegypti In Miami, Fl And Brownsville, Tx, John-Paul Mutebi, André Barretto Bruno Wilke, Erik Ostrum, Chalmers Vasquez, Gabriel Cardenas, Augusto Carvajal, Maday Moreno, William D. Petrie, Arturo Rodriguez, Henry Presas, Jesus Rodriguez, Fred Barnes, Christopher Vitek, Xochitl Estrada, Thalia Rios, Jeremy Marshall

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The diel biting activity of Aedes (Stegomyia) aegypti (L) populations was extensively investigated in the early 1900s to gain more information on the biology of Ae. aegypti, and this information was used to devise effective approaches to controlling populations of this species and protect the human population from widespread arbovirus outbreaks. However, few contemporary studies are available regarding the diel activity patterns of Ae. aegypti. To assess the diel activity patterns of Ae. aegypti in southern Florida and Texas, we conducted 96-h uninterrupted mosquito collections once each month from May through November 2019 in Miami, Florida, and Brownsville, Texas, using …

Ohio Anuran Gut Microbiomes, Serena Hoffman

Undergraduate Honors Thesis Projects

Recent studies focusing on the skin and gut microbiome of vertebrates have found how important microbiomes are to maintaining host health. Understanding the role the gut microbiome plays to host health is of great importance for conservation. Less is known about the gut microbiome than the skin microbiome for amphibians. Literature is especially lacking for local Ohio anuran species. The purpose of this study was to establish the baseline composition of the gut microbiome for local Ohio anurans and to determine whether host species or habitat is the best predictor of gut microbiome composition. Tadpoles were collected from seven different …

Aging-Associated Changes In Motor Function Are Ovarian Somatic Tissue-Dependent, But Berm Cell And Estradiol Independent In Post-Reproductive Female Mice Exposed To Young Ovarian Tissue, Tracy L. Habermehl, Kaden B. Underwood, Kevin D. Welch, Steven P. Gawrys, Kate C. Parkinson, Augusto Schneider, Michal M. Masternak, Jeffrey Mason

Center for Integrated Biosystems Publications

A critical mediator of evolution is natural selection, which operates by the divergent reproductive success of individuals and results in conformity of an organism with its environment. Reproductive function has evolved to support germline transmission. In mammalian ovaries, this requires healthy, active gonad function, and follicle development. However, healthy follicles do not contribute to germline transmission in a dead animal. Therefore, support of the health and survival of the organism, in addition to fertility, must be considered as an integral part of reproductive function. Reproductive and chronological aging both impose a burden on health and increase disease rates. Tremors are …

Neural stem cells, the source of newborn neurons in the adult hippocampus, are intimately involved in learning and memory, mood, and stress response. Despite considerable progress in understanding the biology of neural stem cells and neurogenesis, regulating the neural stem cell population precisely has remained elusive because we have lacked the specific targets to stimulate their proliferation and neurogenesis. The orphan nuclear receptor TLX/NR2E1 governs neural stem and progenitor cell self-renewal and proliferation, but the precise mechanism by which it accomplishes this is not well understood because its endogenous ligand is not known. Here, we identify oleic acid (18:1ω9 monounsaturated …

The Sglt2 Inhibitor Canagliflozin Reduces Androgen Receptor Expression And Nuclear Localization Of Beta-Catenin In Human Prostate Cancer Cells, Kalkidan Bekele, Tunde Smith, Lamonica Stewart

Student Research

Drugs that inhibit the protein sodium-glucose cotransporter-2 (SGLT2) are commonly used in the United States to treat type 2 diabetes. Recent studies suggest that SGLT2 inhibitors reduce growth of lung, liver, and breast cancer cells in vitro. Therefore, administration of SGLT2 inhibitors may also limit the growth of malignant tumors. Previous work from our laboratory has shown that one SGLT2 inhibitor, canagliflozin, reduces the proliferation of C4-2B cells, a castration-resistant human prostate cancer cell line. Concentrations of canagliflozin that reduce proliferation also lower levels of the androgen receptor (AR), a protein known to promote growth of prostate cancers. The goal …

A Comparison Of Natural, Living, And Hardened Shorelines Ability To Prevent Coastal Erosion And Maintain A Healthy Ecosystem, Gabrielle Spellmann

Master's Theses

It is important to find a suitable method to protect the U.S. Gulf Coast shoreline, since its’ low elevation and the Loop current make it vulnerable to sea level rise. I focused on two manmade methods, hardened, and living shorelines, of coastal protection for when the natural marsh suffers excess erosion rates. Living shorelines are a suite of shoreline conservation and restoration techniques that usually involve some sort of hardened structure that dampens wave energy so that the native vegetation behind it can take root and stabilize the shoreline. This study looked at six different sites, all containing a natural, …

Ocean Quahog (Arctica Islandica) Population Dynamics: Sex-Based Demographics And Regional Comparisons In The Northwest Atlantic, Kathleen M. Hemeon

Dissertations

Arctica islandica (ocean quahog) is the longest-lived bivalve on Earth. Individuals on the deep continental shelf of the Mid-Atlantic (US) can survive for centuries, and when found in the colder, boreal waters of Iceland, ages over 500 years can be reached. The ocean quahog is important in the US, yet very little is known about the resiliency of the ocean quahog stock to fishing activity, and ocean quahog recruitment patterns over time. To quantify and constrain age-reader error prior to age analysis, a triple-method error protocol was developed for A. islandica that included age-reader bias, precision, and error frequency. The …

High-frequency accelerometer recording of key predatory behaviors in vipers: validation and case study with Timber Rattlesnakes (Crotalus horridus)

Morgan Thompson, Richard H. Adams, Anna F. Tipton, and Dominic L. DeSantis

Tri-axial accelerometers (ACTs) are becoming increasingly common in studies of animal behavior wherein direct observation of subjects in nature is constrained or impossible. ACTs are small (< 1 g) piezo-electric (spring-like) sensors that measure three-dimensional acceleration (upward, downward, and side-to-side) derived from subject motion. When leveraged with advanced machine learning techniques, these data can enable precise automated classification of a wide range of movement-mediated behaviors. Until recently, ACTs were largely reserved for larger-bodied organisms or those most amenable to the temporary external attachment of devices. Ongoing ACT miniaturization has now expanded the breadth of organisms amenable to these methods. This project aims to expand on a recently developed framework for ACT monitoring in wild-ranging snakes, a group that has been mostly overlooked in biologging applications. We are currently conducting extensive captive validation trials for robust model training and testing to enable classification of predatory behaviors, including striking and ingestion of prey items, in Timber Rattlesnakes (Crotalus horridus). Following captive validation, we will translate this method to the field with a population of C. horridus in the lower Piedmont of middle Georgia to evaluate the efficacy of externally attached ACTs for remote and continuous monitoring of …

Human Adaptation And Morphological Variation: Expanding Diversity In Anatomy Curriculum, Jordan Cass, Cooker Storm

Seaver College Research And Scholarly Achievement Symposium

Introduction: The recent upturn in our nation’s socio-political conversation has fueled interest in ensuring that college curricula is diverse and inclusive. Because human anatomy is ubiquitous across colleges, it may be a valuable avenue to purposefully incorporate topics of diversity in a way that positively impacts our socio-cultural relationships. Providing students with a scientific understanding of our visible differences may mitigate subconscious bias when we see others who have different features. Purpose: We investigated the biogeographical factors that contribute to the morphological variability of the face, hair, and body size; with the secondary aim of developing diverse and …

Endogenous Cftr Expression In Human Epithelial Cell Lines, Zithlaly Amezquita

Undergraduate Research Conference

CFTR (Cystic Fibrosis Transmembrane-conductance Regulator) is a plasma membrane protein that functions as a chloride ion channel on many epithelial cells. There are over 1000 mutations that affect the function of this protein; however, the most common mutation is DF508. CFTR mutations target many secretory organs like pancreas and lungs causing the genetic disease cystic fibrosis (CF), common among Caucasians of northern European origin. Detection of endogenous CFTR expression is possible by a difficult and costly immunoprecipitation method but not by the most used western blotting method. Therefore, the goal of this project was to detect the endogenous CFTR expression …

Size Structure And Intraguild Interactions Between Two Ambystoma Species, Gwyneth Daunton

Theses and Dissertations

Intraguild interactions affect population and community structure through a combination of competition and predation. Changes in size structure influence intraguild interactions by affecting the strength and direction of these species’ interactions. I tested for size-structured intraguild interactions in temporary pond ecosystems between marbled salamanders (Ambystoma opacum) and tiger salamanders (Ambystoma tigrinum) using an outdoor mesocosm experiment. I hypothesized that 1) A. opacum survivorship and growth would be negatively impacted when both species start at a similar size because tiger salamanders grow faster and are more aggressive 2) A. tigrinum will grow slower and have lower survivorship …

Dissecting Mutational Allosteric Effects In Alkaline Phosphatases Associated With Different Hypophosphatasia Phenotypes: An Integrative Computational Investigation, Fei Xiao, Ziyun Zhou, Xingyu Song, Mi Gan, Jie Long, Gennady M. Verkhivker, Guang Hu

Mathematics, Physics, and Computer Science Faculty Articles and Research

Hypophosphatasia (HPP) is a rare inherited disorder characterized by defective bone mineralization and is highly variable in its clinical phenotype. The disease occurs due to various loss-of-function mutations in ALPL, the gene encoding tissue-nonspecific alkaline phosphatase (TNSALP). In this work, a data-driven and biophysics-based approach is proposed for the large-scale analysis of ALPL mutations-from nonpathogenic to severe HPPs. By using a pipeline of synergistic approaches including sequence-structure analysis, network modeling, elastic network models and atomistic simulations, we characterized allosteric signatures and effects of the ALPL mutations on protein dynamics and function. Statistical analysis of molecular features computed for the …

Rapid Pivot Of Cure Wet Lab To Online With The Help Of Instructor Communities, Enid T. González-Orta, Deborah Tobiason, Brittany J. Gasper, Aarti Raja, Sarah Miller

Biology Faculty Articles

The pivot to remote and hybrid learning during the Covid-19 pandemic presented a challenge for many in academia. Most institutions were not prepared to support this rapid change, and instructors were left with the burden of converting a traditional face-to-face course into multiple modalities with very limited preparation time. When institutional support is lacking, we posit that instructor communities of practice can help provide the resources needed to meet the instructional demands. Tiny Earth, a course-based-undergraduate research experience (CURE) and international network of instructors and students, responded to the instructional challenges of the pandemic by leveraging its large community of …
