Dnp Final Report: Psychosocial Screening For Oncology Patients, Robyn V. Beard Apr 2022

Dnp Final Report: Psychosocial Screening For Oncology Patients, Robyn V. Beard

DNP Final Reports

Background: Patients with cancer often face severe distress related to fear of death, body disfigurement, financial stress, and lack of support system. This distress may lead to physical and emotional symptoms that bring patients to seek care at emergency departments, delay care or make poor health choices, and increase utilization of prescription drugs. With the already over burdened healthcare system, addressing these psychosocial needs is vital to improving patients outcomes as well as improving healthcare expenditure. Purpose: The purpose of this evidence based practice project was to improve perceived quality of life for oncology patients through detailed screening and behavioural ...


The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez Apr 2022

The Effects Of Paclitaxel On Cellular Migration And The Cytoskeleton, Ashley Salguero-Gonzalez

Thinking Matters Symposium

In a clinical setting, some patients are exposed to an anti-cancer chemotherapy agent, paclitaxel. Cancerous cells undergo rapid, continuous cell division without control. Chemotherapy treatments try to slow and stop the uncontrollable cell division cycles and eliminate cancerous cells in the process. Paclitaxel serves as a treatment for some types of cancers, including lung, melanoma, bladder, and esophageal. Because it targets the cytoskeleton, paclitaxel can also influence cell migration. This project utilizes a cellular migration assay and an immunohistochemistry assay to analyze the effects of paclitaxel on the movement of cells and on the cytoskeleton of neuroglia rat cells with ...

T Cell Therapy: Underlying Mechanisms And Current Advancements, Griffin Mccloy

Senior Honors Theses

As the second leading cause of death in 2016, cancer is one of the most serious diseases facing the world today. T cell therapy is a current area of research attempting to address the disease with two primary division: CAR-T and TCR-T cell therapy. The immune system naturally produces T lymphocytes to aid in the recognition and removal of cells infected with viruses or transformed into cancer. Under normal circumstances, T lymphocytes identify and destroy cancerous cells; however, some cancerous cell types can evade this system. With the use of genetic editing technology, T lymphocytes can gain the ability to ...


An Analysis Of The Psychological And Physical Effects Of A Physical Activity Program During In-Patient Pediatric Cancer Treatment, Zoë Winters Apr 2022

An Analysis Of The Psychological And Physical Effects Of A Physical Activity Program During In-Patient Pediatric Cancer Treatment, Zoë Winters

Undergraduate Theses

There is limited published research regarding the use of physical activity in cancer treatment programs, and even fewer in pediatric treatment plans; however, there is a common consensus that following the conclusion of cancer treatment an individual’s physical fitness has been majorly impacted. The inactivity that commonly coexists with cancer treatment often results in extended periods of time in rehabilitation programs and decreased independence. Along with the physical detriments caused by inactivity, increased dependence on others often brings about feelings of helplessness that can further cause emotional detriments. It has however been demonstrated in previous research that adding physical ...


The Role Of Mtorc1 In Autophagy As It Relates To Cancer, Olivia Robinson Apr 2022

The Role Of Mtorc1 In Autophagy As It Relates To Cancer, Olivia Robinson

Senior Honors Theses

The mammalian target of rapamycin complex 1, mTORC1, is composed of several subunit proteins with many cellular responsibilities including participation in a complex cell signaling cascade leading to autophagy, which is the regulated degradation of cell components. mTORC1 is frequently mutated or dysregulated within human cancer. Normally, mTORC1 functions to provide efficient regulation of autophagy according to intracellular levels of growth factors, amino acids, nutrients, oxygen levels, and more that can either inhibit mTORC1 and upregulate autophagy or activate mTORC1 and downregulate autophagy. A better understanding of mTORC1 is imperative to preparing cancer therapy treatments. Various cancerous tissue types require ...


The Effects Of Floatation-Rest On Cortisol Levels Of Patients With Glioblastoma Grade Iv: A Conceptual Framework, Hilario Gomez Apr 2022

The Effects Of Floatation-Rest On Cortisol Levels Of Patients With Glioblastoma Grade Iv: A Conceptual Framework, Hilario Gomez

Selected Honors Theses

Glioblastoma is reported to be the most aggressive and common brain tumor in adults (Davis, 2016). To help alleviate pain in patients with glioblastoma, floatation-REST (Restricted Environmental Stimulation Technique) is proposed. Such therapy has been shown to benefit chronic tension headaches, muscle tension, and other stress-related pain conditions (Feinstein, 2018). The magnesium and sulfate components of Epsom salt combined with controlled warm water allow the muscles and joints to relax. Studies show that magnesium targets the Adrenocorticotropic Hormone (ACTH) produced by the Anterior Pituitary Gland which in turn affects cortisol hormone levels to activate the body's immune defenses and ...

Challenges And Opportunities For Immunotherapeutic Intervention Against Myeloid Immunosuppression In Glioblastoma, Mark A Exley, Samantha Garcia, Amelia Zellander, Jenny Zilberberg, David W. Andrews

Department of Neurosurgery Faculty Papers

Glioblastoma multiforme (GBM), the most common and deadly brain cancer, exemplifies the paradigm that cancers grow with help from an immunosuppressive tumor microenvironment (TME). In general, TME includes a large contribution from various myeloid lineage-derived cell types, including (in the brain) altered pathogenic microglia as well as monocyte-macrophages (Macs), myeloid-derived suppressor cells (MDSC) and dendritic cell (DC) populations. Each can have protective roles, but has, by definition, been coopted by the tumor in patients with progressive disease. However, evidence demonstrates that myeloid immunosuppressive activities can be reversed in different ways, leading to enthusiasm for this therapeutic approach, both alone and ...


Dna-Pkcs: A Targetable Protumorigenic Protein Kinase., Emanuela Dylgjeri, Karen E Knudsen Feb 2022

Dna-Pkcs: A Targetable Protumorigenic Protein Kinase., Emanuela Dylgjeri, Karen E Knudsen

Department of Cancer Biology Faculty Papers

DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is a pleiotropic protein kinase that plays critical roles in cellular processes fundamental to cancer. DNA-PKcs expression and activity are frequently deregulated in multiple hematologic and solid tumors and have been tightly linked to poor outcome. Given the potentially influential role of DNA-PKcs in cancer development and progression, therapeutic targeting of this kinase is being tested in preclinical and clinical settings. This review summarizes the latest advances in the field, providing a comprehensive discussion of DNA-PKcs functions in cancer and an update on the clinical assessment of DNA-PK inhibitors in cancer therapy.

Choosing To Thrive: An Autoethnographic Journey Of Cancer, Companionship, And Carrots, Bruce Lilyea

The Qualitative Report

In this autoethnography, I explore the companionship experience of someone supporting a cancer patient who is endeavoring to thrive in the face of this disease. A wide range of studies has been conducted on the emotional and social issues relating to cancer and specifically to breast cancer. Appropriately, most of the research relating to the personal narrative focuses on the stories of the person who has been diagnosed with cancer, and limited research has highlighted the perspective and experiences of their companions. My primary goals for this autoethnographic research are to: (1) Begin to answer the question: What role do ...

Positive Selection And Enhancer Evolution Shaped Lifespan And Body Mass In Great Apes, Daniela Tejada-Martinez, Roberto A Avelar, Inês Lopes, Bruce Zhang, Guy Novoa, João Pedro De Magalhães, Marco Trizzino

Department of Biochemistry and Molecular Biology Faculty Papers

Within primates, the great apes are outliers both in terms of body size and lifespan, since they include the largest and longest-lived species in the order. Yet, the molecular bases underlying such features are poorly understood. Here, we leveraged an integrated approach to investigate multiple sources of molecular variation across primates, focusing on over 10,000 genes, including approximately 1,500 previously associated with lifespan, and additional approximately 9,000 for which an association with longevity has never been suggested. We analyzed dN/dS rates, positive selection, gene expression (RNA-seq), and gene regulation (ChIP-seq). By analyzing the correlation between dN ...

Department of Medical Oncology Faculty Papers

Background: Older adults (≥65 years) with gastrointestinal (GI) cancers who receive chemotherapy are at increased risk of hospitalization caused by treatment-related toxicity. Geriatric assessment (GA) has been previously shown to predict risk of toxicity in older adults undergoing chemotherapy. However, studies incorporating the GA specifically in older adults with GI cancers have been limited. This study sought to identify GA-based risk factors for chemotherapy toxicity-related hospitalization among older adults with GI cancers.

Patients and methods: We performed a secondary post hoc subgroup analysis of two prospective studies used to develop and validate a GA-based chemotherapy toxicity score. The incidence of ...

All Works

Vitamin D3 has many important health benefits. Unfortunately, these benefits are not widely known among health care personnel and the general public. As a result, most of the world’s population has serum 25-hydroxyvitamin D (25(OH)D) concentrations far below optimal values. This narrative review examines the evidence for the major causes of death including cardiovascular disease, hypertension, cancer, type 2 diabetes mellitus, and COVID-19 with regard to sub-optimal 25(OH)D concentrations. Evidence for the beneficial effects comes from a variety of approaches including ecological and observational studies, studies of mechanisms, and Mendelian randomization studies. Although randomized controlled ...


A Literature Resource For Those Supporting Patients With Autism Spectrum Disorder And Cancer, Kaylee James Jan 2022

A Literature Resource For Those Supporting Patients With Autism Spectrum Disorder And Cancer, Kaylee James

Psychology Doctoral Specialization Projects

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that impacts both social interaction and patterns of behavior. ASD is rooted in genetic, biological, and environmental causes. Cancer begins when cells grow out of control and there is also a genetic and biological cause of cancer. There is an overlap between the genetic and biological causes of ASD and cancer. As a result, evidence supports an increased risk of developing some types of cancer as well as protective factors for some times of cancer for individuals with ASD. Therefore, individuals with ASD may be at a heightened risk to develop cancer ...

3d Bioprinting And Implantation Of Mouse Mammary Epithelial Structures Using A Custom Accessible 3d Bioprinting Platform, Xavier-Lewis Palmer, Saad Jafri, Patrick C. Sachs, Robert D. Bruno

College of Engineering & Technology (Batten) Posters

Prior work has shown that our bioprinting system can reliably produce human mammary organoids and tumoroids with high precision. However, this was not previously applied to mouse models, which are also important with respect to translational research in cancer drug development. To address this, we have produced protocols for the development of in vitro structures from murine mammary epithelial and tumor cells. Additionally, we assessed the translatability of both human and murine bioprinted organoids into mouse mammary fat pads over a period of 6 weeks. Our lab found that our produced organoids are reliable, they can survive in vivo, and ...

3d Bioprinted Structures From Cells Of Non-Epithelial Mesodermal And Endodermal Lineage Using A Custom Accessible 3d Bioprinting Platform, Xavier-Lewis Palmer, Annette Berkin, Patrick C. Sachs, Robert D. Bruno

College of Engineering & Technology (Batten) Posters

Prior work within our lab has demonstrated the ability to print both murine and human mammary organoids and tumoroids in vitro that can also be reliably transplanted into a murine host for translational studies. Peripherally, this bioprinting system has also been used for 3D printing neurons, stem cells, cancer cells, and a primary cell line rich with fibroblasts, but each of these efforts were with cells of ectodermal lineage. Thus, the system's capacity for use on cells of other origins had been untested. To address this, we have now developed protocols for cells of endodermal and non-epithelial mesodermal/mesenchymal ...

Plasmonic-Based Biosensor For The Early Diagnosis Of Prostate Cancer, Thakshila Liyanage, Bayan Alharbi, Linh Quan, Aurora Esquela-Kerscher, Gymama Slaughter

Bioelectrics Publications

A tapered optical fiber (TOF) plasmonic biosensor was fabricated and used for the sensitive detection of a panel of microRNAs (miRNAs) in human serum obtained from noncancer and prostate cancer (PCa) patients. Oncogenic and tumor suppressor miRNAs let7a, let-7c, miR-200b, miR-141, and miR-21 were tested as predictive cancer biomarkers since multianalyte detection minimizes false-positive and false-negative rates and establishes a strong foundation for early PCa diagnosis. The biosensing platform integrates metallic gold triangular nanoprisms (AuTNPs) laminated on the TOF to excite surface plasmon waves in the supporting metallic layer and enhance the evanescent mode of the fiber surface. This sensitive ...


Optimization Of The Structure Of Ttr Ligands For Half-Life Extension (Tlhe), Guanming Jiang Jan 2022

Optimization Of The Structure Of Ttr Ligands For Half-Life Extension (Tlhe), Guanming Jiang

University of the Pacific Theses and Dissertations

Many potential therapeutic agents face challenges for their clinical development due to short circulation half-life. As a result, prolonging the half-life of therapeutic drugs in circulation while preserving their hydrophilicity and small size will be a key step toward more effective and safe pharmacological molecules. Our lab developed a new approach for enhancing the safety and efficacy of therapeutic agents. By endowing therapeutic agents with a hydrophilic small molecule (a derivative of the clinical candidate, AG10) which reversibly binds to the serum protein transthyretin (TTR), the half-life of the therapeutic agent should be extended by binding to the TTR in ...
