Mathematically Modeling How Trapping Regimes That Target Specific Crayfish Life Stages Impact Removal Efficacy, Rini Pattison

Seaver College Research And Scholarly Achievement Symposium

The red swamp crayfish, Procambarus clarkii, is an invasive species introduced into several streams within the Santa Monica Mountains (SMM) in Southern California. Crayfish predation decimates native aquatic species. Thus, the Mountains Restoration Trust (MRT) and Environmental Restoration Group have worked to remove crayfish through regular trapping in Malibu Creek.

To aid conservation efforts, former SURB students William Milligan and Dev Patel developed mathematical models of crayfish removal efficacy. Milligan created a differential equation model of how crayfish removal affects local newt populations. Patel expanded Milligan’s crayfish model by creating a discrete model of the crayfish life cycle that newly …

γδ T cells play an important role in disease control in acute myeloid leukemia (AML) and have become an emerging area of therapeutic interest. These cells represent a minor population of T lymphocytes with intrinsic abilities to recognize antigens in a major histocompatibility complex-independent manner and functionally straddle the innate and adaptive immunity interface. AML shows high expression of phosphoantigens and UL-16 binding proteins that activate the Vδ2 and Vδ1 subtypes of γδ T cells, respectively, leading to γδ T cell-mediated cytotoxicity. Insights from murine models and clinical data in humans show improved overall survival, leukemia-free survival, reduced risk of …

Faculty, Staff and Student Publications

INTRODUCTION: Although the concept of hope is highly relevant for cancer patients, little is known about its association with cancer-relevant biomarkers. Here we examined how hope was related to diurnal cortisol and interleukin-6 (IL-6), a pro-inflammatory cytokine previously associated with tumor biology and survival in ovarian cancer. Secondly, we examined whether hope and hopelessness are distinctly associated with these biomarkers.

METHOD: Participants were 292 high-grade ovarian cancer patients who completed surveys and provided saliva samples 4x/daily for 3 days pre-surgery to assess diurnal cortisol. Blood (pre-surgery) and ascites were assessed for IL-6. Hope and hopelessness were assessed using standardized survey …


Making The Connection: How Membrane Contact Sites Have Changed Our View Of Organelle Biology, G. Voeltz, E. Sawyer, G. Hajnóczky, W. Prinz Jan 2024

Making The Connection: How Membrane Contact Sites Have Changed Our View Of Organelle Biology, G. Voeltz, E. Sawyer, G. Hajnóczky, W. Prinz

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The view of organelles and how they operate together has changed dramatically over the last two decades. The textbook view of organelles was that they operated largely independently and were connected by vesicular trafficking and the diffusion of signals through the cytoplasm. We now know that all organelles make functional close contacts with one another, often called membrane contact sites. The study of these sites has moved to center stage in cell biology as it has become clear that they play critical roles in healthy and developing cells and during cell stress and disease states. Contact sites have important roles …


Female Biology, Jennifer Dever Jan 2024

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 …


Investigating Scube3 Nuclear Localization In Presence Of Doxorubicin Treatment In Triple Negative Breast Cancer Cells, Lillian Ergle Jan 2024

Investigating Scube3 Nuclear Localization In Presence Of Doxorubicin Treatment In Triple Negative Breast Cancer Cells, Lillian Ergle

Merge

Signal peptide-CUB-EGF-like domain-containing protein 3 (SCUBE3) is a glycosylated secreted protein. Prior to its secretion, SCUBE3 localizes in the cytoplasm. We observed that SCUBE3 protein trans-localized to the nucleus following Doxorubicin (DOX) treatment. DOX is one of the strongest chemotherapeutic agents and the first-line drug used in breast cancer treatment. SCUBE3 structural analysis showed that it lacks a DNA binding domain. Based on this observation and other preliminary data, we hypothesized that nuclear SCUBE3 protein promotes the survival of cells against Doxorubicin treatment. To investigate this hypothesis, we made a wild-type construct and three constructs with mutated nuclear localization sequences …

Emerald ash borer (EAB), Agrilus planipennis, is an invasive pest that significantly impacts olive trees (Olea europaea). This study aimed to assess the role of abiotic stress factors such as drought and salinity in influencing plant defenses and resistance to EAB, while also examining cultivar variation in resistance. The study specifically aimed to address: (1) What effects do varying degrees of abiotic stress (drought, salinity) have on olive trees' antioxidant and peroxidase activity in olive tree? (2) Do distinct olive cultivars exhibit varying levels of resistance to EAB under various stressors? We used a controlled experimental design with two stress …

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

UROP 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 …

Carry-Over Effects Of Climate On Prothonotary Warbler (Protonotaria Citrea) Feather Quality, Alyssa N. Spasic, Dan Albrecht-Mallinger, Lesley Bulluck

UROP Posters

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 …

Softening And Cross-Susceptibility: Exposure To Heat And Desiccation Reduces Future Stress Tolerance In An Insect, Lauren Harter Jan 2024

Softening And Cross-Susceptibility: Exposure To Heat And Desiccation Reduces Future Stress Tolerance In An Insect, Lauren Harter

University of the Pacific Theses and Dissertations

The frequency and duration of environmental stressors, such as heat waves and drought, will continue to grow due to ongoing climate change, thereby increasing the likelihood that organisms will experience stressors consecutively. Exposure to one stressor can improve or impair future tolerance to the same stressor (i.e., hardening or softening, respectively), or enhance or reduce future tolerance to a different stressor (i.e., cross-protection or cross-susceptibility, respectively). Understanding whether stress improves or impairs animals’ abilities to withstand future stressors is critical for determining the physiological sensitivity of animals to ongoing climate change. Here, I evaluated the responses to consecutive heat and …
