Female Biology, Jennifer Dever
Female Biology, Jennifer Dever
All USF Faculty Authored Books
Over twenty years ago I developed a course for the upper- level biology major at the University of San Francisco called
Female Biology. This was from what I perceived as a gap in the undergraduate biology curriculum- students were not learning about the evolutionary aspects of being female and studying the specific health-related issues unique to women. The information in the most widely used general biology textbooks written from a male perspective, focuses on research gained from male models by work conducted in male-led laboratories. There still exists a problem with a lack of adequate representation of women in biomedical …
How Does A Global Climate Cycle Affect The Reproductive Output Of A Neotropical Migratory Bird?, Abby K. Bressette, Emma Cummings, Daniel Albrecht-Mallinger, Lesley Bulluck
How Does A Global Climate Cycle Affect The Reproductive Output Of A Neotropical Migratory Bird?, Abby K. Bressette, Emma Cummings, Daniel Albrecht-Mallinger, Lesley Bulluck
Undergraduate Research Posters
El-Niño Southern Oscillation (ENSO) causes regional changes in climate and has been found to have varying effects on the survival, fecundity, and recruitment of migratory songbirds. This study seeks to better understand the effect of ENSO on the fecundity of Virginia-breeding Prothonotary warbler (Protonotaria citrea; PROW), a neotropical migratory songbird. PROW breed in the Eastern United States and spend the non-breeding season primarily in Panama and Colombia. Ongoing research in Virginia has found a positive relationship between spring precipitation and predicted number of PROW fledgelings during La Niña, but the opposite during El Niño. To better understand this relationship, we …

Avian species have inspired numerous studies on ornamentation, exploring its role in intra- and intersexual selection as a marker for individual quality. Male birds have been the focus of most of these studies while females, which can also display ornamentation, have been studied less. Coloration achieved through molt, particularly carotenoid-based pigments, requires energy derived from food resources. As climate affects insect abundance, there may be a link between climate conditions during molt and feather quality the following season. We assessed the relationship between temperature and precipitation during molt and female Prothonotary Warbler (Protonotaria citrea) breast and crown feather reflectance metrics …

Blow flies are the primary colonizers of human cadavers. In many death investigations, insect evidence can help in prediction of minimum post-mortem interval (PMImin) but to do that, the first step is to identify collected insect evidence. For immature stages, morphological keys are either limited or incomplete and hence DNA based identification is used. For DNA based ID, DNA extraction is the first and the most important step, especially when collected evidence is highly degraded. The main aim of this study was to compare three DNA extraction methods (QIAgen Blood and Tissue Kit, organic, and QIAgen DNA Investigator Kit) to …

ROS and SFK signaling is required for development of hematopoietic stem cells in zebrafish
Bradley Williams and Erich Damm
Background
Hematopoiesis is the process in which the myriad of mature blood cell types, including erythrocytes and leukocytes, develop from hematopoietic stem cells (HSCs) throughout the life of an organism. In vertebrates, HSCs originate from endothelial cells lining the floor of the dorsal aorta. This process is referred to as the endothelial to hematopoietic transition and is likely controlled in part by molecular signals from neighboring cells. Investigation into the molecular signaling mechanisms controlling the development of HSCs is critical to …

During the construction of VCU’s Hermes A. Kontos Medical Sciences Building in April 1994, nineteenth century ancestral remains were found in an abandoned well on the Medical College of Virginia (MCV) campus. This well, now known as the East Marshall Street Well (EMSW), is thought to have been used as a disposal location for cadaver dissection for surgical and other medical waste in the past. VCU is now seeking to use DNA sequencing technology to match and assemble bones from each individual for a proper burial, uncover the cultural and historical context in which these people lived, and bring a …
Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh
Undergraduate Research Posters
Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

Ecological Stressors Impact Soil Biodiversity, Kaleb Frierson, John Carlile
Ecological Stressors Impact Soil Biodiversity, Kaleb Frierson, John Carlile
Transformations: Presentation Slides
Soil biodiversity serves ecologically important roles like nutrient cycling and is used as an indicator of community disturbance. North American forests host a multitude of ecological stressors, including invasive plants, earth worms, and deer abundance. While relationships between deer and invasive species, as well as relationships between macroinvertebrates and worms have been heavily investigated, the effects of invasive plant species like Pale Swallowwort on soil biodiversity are unknown. To test our hypothesis that Pale Swallowwort affects soil biodiversity, we collected leaf litter from three state parks throughout Central New York at sites with and without the invasive plant. Samples were …

Effects Of Specific Blocking Buffers On Histone H2b Antibodies, Noha Al-Saadi, Grace Mix, Mardasia Thompson, Elin Zaman
JSU Student Symposium 2022
Mammalian histones have been known to be one of the most highly alkaline proteins found in the nuclei. Their main function is to organize DNA into chromosomes and regulate transcription. An example of a histone would be Histone H2B, which this project focuses heavily on. Histone H2B has been seen to bind poorly to antibodies and result in a weak signal. The goal of this project is to test a multitude of blocking buffers, in triplicate, in order to find a blocking buffer that can obtain the strongest signal from the antibodies being tested. Through the use of protein gel …
Antioxidant Content In Plant-Based Diets Versus Meat-Based Diets, Lia Meadows, Peeper Walker, Reveca Tomas
Antioxidant Content In Plant-Based Diets Versus Meat-Based Diets, Lia Meadows, Peeper Walker, Reveca Tomas
JSU Student Symposium 2022
The result of naturally occurring free radicals in the body are oxidative-stress-related damages to cells, tissues, and biomolecules. Oxidative stress occurs when the balance between reactive oxygen species (ROS) outnumbers antioxidants, producing negative effects. Antioxidants exist as a natural defense mechanism utilized by the body. This defense exists in two distinct forms: enzymatic and non-enzymatic antioxidants. Non-enzymatic antioxidants consist of vitamins and bioactive compounds, such as phenols. In previous studies, plant-based diets showed promising results in reducing damage caused by oxidative-stress. The purpose of this study was to determine the extent to which antioxidant concentration differs between meat-based diet and …
An Exploration Of Trex1 Variants Of Uncertain Significance And Their Potential Impact On Autoimmunity In Systemic Lupus Erythematosus And Aicardi-Goutieres Syndrome, Jordan Peters
JSU Student Symposium 2022
TREX1 is a gene responsible for encoding a 3'-to-5' DNA exonuclease in human cells. Under normal conditions TREX1 removes bases from the free 3' end to enhance DNA damage and prevent DNA end reannealing and rapid repair. Mutations in TREX1, which result in the absence of the 3'-to-5' DNA exonuclease and the intracellular accumulation of unneeded DNA and RNA, have been shown to trigger immune dysfunction leading to diseases such as systemic lupus erythematosus (SLE) and Aicardi-Goutières Syndrome (AGS). The goal of this study is to determine the potential impact of a TREX1 missense mutation with uncertain clinical significance (VUS). …
Genetic Assessment Of Congenital Stationary Night Blindness-Associated Trpm1 Variants Of Uncertain Significance In C. Elegans, Sara Morris
JSU Student Symposium 2022
Congenital stationary night blindness (CSNB) is a disorder of the eye that impacts the ability to see in low to no light conditions. It occurs in horses and humans. TRPM1 encodes for a member of the transient receptor potential melastatin subfamily of transient receptor potential ion channels. Mutations in TRPM1 have been identified by previous researchers in horses with leopard complex pattern (LCP) suffering also from CSNB. Phenotypic changes in these horses are a loss of spotted coat pattern. An attempt was made to locate variants of uncertain significance (VUS) in TRPM1 that had been previously identified in horses with …

Using Ecological Niche Modeling To Predict The Response Of Hydrocotyle Bonariensis To Global Climate Change, Rachel Bonner, Laura K. Dease, Elizabeth A. Hughston
JSU Student Symposium 2022
Coastal dune habitats provide valuable ecosystem services but are declining globally due to the interacting effects of multiple stressors, including global climate change (GCC). To explore the potential severity of the effects of GCC on dune plant communities of the Northern Gulf of Mexico and surrounding areas, we modeled the fundamental bioclimatic niche of a dune plant species, largeleaf pennywort (Hydrocotyle bonariensis Comm. ex Lam.), in this region. We then projected its niche to estimate habitat suitability under current and future environmental conditions. Occurrence records were mined from the Global Biodiversity Information Facility, cleaned, then thinned by spatial filtering, …
Characterization Of Anti-Microbial Properties Of Excrement And Functional Microbiome Of New World Vultures In Alabama, Bridgette Gray
Characterization Of Anti-Microbial Properties Of Excrement And Functional Microbiome Of New World Vultures In Alabama, Bridgette Gray
JSU Student Symposium 2022
Two distinct species of New World vultures are native to North America and inhabit Alabama, black vultures (Coragyps atratus) and turkey vultures (Cathartes aura). They are scavengers that consume decaying carcasses or carrion, which helps reduce the spread of disease. Vultures are susceptible to declining population numbers as they have been trapped and killed due to the belief that they spread disease, additionally contact with poisons and habitat destruction have also led to their decline. Currently, these two vultures are one of the seven vulture species with least concern and stable in Alabama and the world. However, it is important …
Diving Into The Unknown: A Genetic Investigation Of Type-2 Diabetes-Associated Insr Variants Of Uncertain Significance, Trinity Elston
Diving Into The Unknown: A Genetic Investigation Of Type-2 Diabetes-Associated Insr Variants Of Uncertain Significance, Trinity Elston
JSU Student Symposium 2022
Type 2 diabetes is a complex metabolic disorder with interactions between genetic and environmental factors, making it more complicated to understand the clinical implications of identified genetic variants and disease pathology. Many of the diabetes-associated variants are currently classified as VUS and occur within the genes involved in insulin signaling and regulation, so we turned our focus on the human INSR gene. INSR encodes the insulin receptor protein that plays a major role in insulin signaling. Furthermore, C. elegans provides a simple model system to examine the functional consequences of these diabetes-associated VUS. We examined INSR diabetes-associated VUS through the …

Hematopoietic Stem Cells (HSCs) are the self-renewing population of cells that generate all erythrocytes and leukocytes over the lifetime of a vertebrate organism. HSCs are also the therapeutic units of curative bone marrow transplants used in the treatment of blood malignancies and in gene therapy for genetic blood disorders. In all vertebrate embryos, HSCs originate from the floor of the embryonic dorsal aorta during the endothelial to hematopoietic transition. Nascent HSCs will bud into the blood vessel and be carried to maturation sites by the embryonic blood flow. Despite the curative potential of HSC transplants in blood disorders, this approach …

Background: Opioids are a class of drugs that are utilized in clinical settings to alleviate acute and chronic pain, but can often lead to development of tolerance, addiction and overdose following prolonged usage. Opioids such as morphine function by activating endogenous µ opioid receptors, which are located in various tissues throughout the body. Astrocyte Elevated Gene-1 (AEG-1) is a multifunctional protein that regulates inflammation, myeloid cell activity and lipid metabolism. Studies have shown interactions and overlaps in cellular signaling between the inflammatory/immune responses and the endogenous opioid system which could suggest a role for AEG-1 in opioids effects. Our goal …
