Implementation And Sustainability Of Trauma-Informed Care Via Multi-Tiered System Of Support (Mtss), Aisha Larie Elloie Brice Jan 2022

Implementation And Sustainability Of Trauma-Informed Care Via Multi-Tiered System Of Support (Mtss), Aisha Larie Elloie Brice

University of the Pacific Theses and Dissertations

Trauma-informed care is a relatively new construct in K-12 education, and districts across the United States are seeking avenues to meet the needs of their students. The COVID-19 pandemic elevated the need for districts to develop appropriate supports to address student and adult trauma. Traumatic events can affect a child’s mental, physical, social-emotional, and/or spiritual well-being (Substance Abuse and Mental Health Service Administration, 2011). Furthermore, children with an elevated risk of trauma may not be able to access these supports outside of the school setting (Baweja et al., 2015). Therefore, educational systems need to develop trauma-informed care models for schools …


The Role Of Rad51 In Trichomonas Vaginalis, Dominique Hall Jan 2022

The Role Of Rad51 In Trichomonas Vaginalis, Dominique Hall

University of the Pacific Theses and Dissertations

Drug resistance to the current treatments on the market is on the rise, therefore there is strong interest in understanding what could be causing the resistance, how resistance could be spreading through the population, and finding some possible new drug targets. One protein of interest is Radiation Sensitive Protein 51 (Rad51). It is a protein that is involved in homologous recombination as well as other processes such as DNA damage repair. While Trichomonas vaginalis traditionally has been known to replicate via binary fission, a modified form of closed mitosis, there is some evidence that meiosis, or at least some form …


Spouses Of First Responders: A Narrative Inquiry Of Survival, Recovery And Healing, Jennifer D. Geiger Jan 2022

Spouses Of First Responders: A Narrative Inquiry Of Survival, Recovery And Healing, Jennifer D. Geiger

University of the Pacific Theses and Dissertations

The nature of the work of emergency responders (i.e., firefighters, law enforcement, paramedics, and dispatch) includes high stress and direct experiences of traumatic situations. The experience of posttraumatic stress is common. The spouse or significant other is often the first person to see a change in their responder and the person most likely to be sought out for support from the responder, yet there is little support for the spouses or significant others of emergency workers. The purpose of this qualitative study using in-depth interviews and narrative inquiry was to learn about participants’ experiences at the 6-day residential treatment (retreat) …

UROP Posters

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 …

The Relationship Between Social Media Use And Depression And Anxiety Symptoms During Covid-19, Tene'sha L. Crews, Christina Sheerin

UROP Posters

The rise of the coronavirus (COVID-19) pandemic has caused a global surge in exposure to disaster and crisis-related media. Increases in poor mental health outcomes such as anxiety and depression, are associated with increased exposure to such media content (Abbas et al., 2021; Riehm et al., 2020; Zhao & Zhou, 2020). In recent years, social media has become one of the most widely used sources for news; approximately 48% of adult Americans receive their news from social media (Pew Research Center, 2021). During the COVID-19 pandemic, there has been an increase in social media use due to social distancing and …

The scope of this project was to design, synthesize and test targeted nanoparticles containing hydrophobic and hydrophilic drugs that promote browning in adipose tissue. For hydrophilic drugs the use of liposomes and their hydrophilic core is more useful than the PLGA nanoparticles which have hydrophobic cores. The inhibition of the FOXO1 pathway and modulation of autophagy in adipose tissue can promote browning of white adipose tissue, or an energy burning state where excess energy is burned as heat instead of stored in the cell. If successful, these drugs would offer an alternative treatment for obesity where changes to the patient's …

Computer Science Faculty Publications

After myocardial infarction, the massive death of cardiomyocytes leads to cardiac fibroblast proliferation and myofibroblast differentiation, which contributes to the extracellular matrix remodelling of the infarcted myocardium. We recently found that myofibroblasts further differentiate into matrifibrocytes, a newly identified cardiac fibroblast differentiation state. Cardiac fibroblasts of different states have distinct gene expression profiles closely related to their functions. However, the mechanism responsible for the gene expression changes during these activation and differentiation events is still not clear. In this study, the gene expression profiling and genome-wide accessible chromatin mapping of mouse cardiac fibroblasts isolated from the uninjured myocardium and the …

Man Vs Machine: How Will Artificial Intelligence And Machine Learning Systems Impact Cancer Diagnosis And The Patient-Physician Relationship?, Aditya Kotha, Faye Prichard

UROP Posters

Oncologic diagnosticians are physicians who specialize in interpreting diagnostic exams to diagnose cancer in patients. Software companies have been developing artificial intelligence (AI) systems to interpret these exams to diagnose cancer. These AI systems may affect the traditional role of oncologic diagnosticians if they were to be implemented in the clinical setting. Therefore, I set out to answer my research question: How will AI and machine learning systems impact the roles of oncologic diagnosticians in diagnosing cancer and the patient-physician relationship? By analyzing surveys and studies, I examined the attitudes of oncologic diagnosticians versus cancer patients toward implementing AI systems …

Refugees often experience a lot of stress and trauma before relocating to their host country (Leo, 2021). Additionally, they often continue to experience different challenges while adapting to their new environment (Leo, 2021). Refugees who relocate may experience survivor’s guilt, gratitude to their host country, or may not feel like a member in their new community. On top of new challenges and stressors, refugee students who are the first in their families to attend college feel pressure to excel academically in a way to ‘give back’ to their family and their host country (Turjanmaa & Jasinskaja-Lahti, 2020). Although there has …

BACKGROUND: In the U.S., the Latinx community is growing at a faster rate than any other racial and ethnic minority group. Members of this community have been found to experience a number of acculturative stressors after immigrating including xenophobia, racism, and discrimination. Although several scales have been created in recent years to measure acculturative stress in Spanish-speaking immigrants, they are long, do not have nuanced subscales, or have not been validated in an extremely diverse sample of Latinx immigrants.

OBJECTIVE: The purpose of the current study was to translate and psychometrically validate the Riverside Acculturative Stress Inventory (RASI) in a …

The placenta, responsible for intrauterine development, can facilitate modifications within the placental epigenome in response to changes in the mother. In turn these changes have the potential to also influence the neonate1. Pain relief during delivery is widely used and frequently involves the use of nitrous oxide (N2O, commonly referred to as laughing gas), and pudendal blocks. These treatments, alone or in combination, are generally accepted as safe methods of providing pain relief to mothers. However, laughing gas and local anesthetics such as the ones used during pudendal blocks have been known to cross the placental …

Covid-19 Impact And The Association Between Sociodemographic, Social Support, Depression, And Anxiety In The Mindful Moms Program, Ashley Nguyen

UROP Posters

Background: The Covid-19 Pandemic lockdown resulted in lessened social support and a higher incidence of depressive symptoms in the United States. Low-income families were more likely to have experienced negative impacts on income, access to mental health treatment, stress, and discord within the family, and higher anxiety scores during the pandemic. Minority groups had higher COVID-19 incidence and mortality rates. More than 1 in 5 pregnant women in the United States experience clinically significant depressive symptoms, with marginalized populations carrying a greater burden. Maternal depression is linked to poor maternal and child health outcomes.

UROP Posters

The anterior cruciate ligament (ACL) connects to bone via structurally complex insertions known as entheses that translate load from elastic ligament and stiff bone via gradients in organization, composition, and cell phenotype [1]. These gradients are not recreated in graft repair or engineered replacements, yielding limited repair options and high failure rates [2]. Previously, we developed a culture system that uses a tensile-compressive interface to guide ligament fibroblasts to develop early postnatal-like entheses by 6 weeks [3]; however, cells used were isolated from the entirety of the neonatal bovine ACL from bone to bone and likely contained multiple cell phenotypes …

UROP Posters

Volumetric muscle loss (VML) has been found to overwhelm muscle regeneration, resulting in loss of long-term muscle functionality. Decellularized muscle matrices (DMMs) provide an effective environment for muscle regeneration; however, the age of their source has not been adequately explored for clinical translation. Advanced glycation end-products (AGEs) are chemical cross-links that contribute to the aging process by accumulating on collagen fibers, resulting in a stiffening of the collagenous matrix and an increase in inflammation via the receptor for advanced glycation end-products (RAGE). In previous experiments, we found increased levels of AGE-specific cross-links within DMMs in old mice compared to young …

The objective of this experiment is to observe the effect of gravitropism on the orientation of Brassica rapa (B. rapa) roots. Specifically, amyloplasts that reside at the bottom of root tips act as gravity sensors. As plants are disturbed from upright orientation, roots automatically grow according to the downward pull of gravity. It is hypothesized that as the angle of rotation increases, the angle of root growth is inversely proportional. Five plants containing four seeds of B. rapa were grown over the course of 10 days. Each plates, aside from the control, were rotated once 90°, 80°, and 270° to …

Our subjective visual experiences involve complex interaction between our eyes, our brain, and the surrounding world. It gives us the sense of sight, color, stereopsis, distance, pattern recognition, motor coordination, and more. The increasing ubiquity of gaze-aware technology brings with it the ability to track gaze and pupil measures with varying degrees of fidelity. With this in mind, a review that considers the various gaze measures becomes increasingly relevant, especially considering our ability to make sense of these signals given different spatio-temporal sampling capacities. In this paper, we selectively review prior work on eye movements and pupil measures. We first …

The high level of sparsity in methylome profiles obtained using whole-genome bisulfite sequencing in the case of low biological material amount limits its value in the study of systems in which large samples are difficult to assemble, such as mammalian preimplantation embryonic development. The recently developed computational methods for addressing the sparsity by imputing missing have their limits when the required minimum data coverage or profiles of the same tissue in other modalities are not available. In this study, we explored the use of transfer learning together with Kullback-Leibler (KL) divergence to train predictive models for completing methylome profiles with …

Technical drawings used for illustrating designs are ubiquitous in patent documents, especially design patents. Different from natural images, these drawings are usually made using black strokes with little color information, making it challenging for models trained on natural images to recognize objects. To facilitate indexing and searching, we propose an effective and efficient visual descriptor model that extracts object names and aspects from patent captions to annotate benchmark patent figure datasets. We compared two state-of-the-art named entity recognition (NER) models and found that with a limited number of annotated samples, the BiLSTM-CRF model outperforms the Transformer model by a significant …
