The Acquisition And Analysis Of Electroencephalogram Data For The Classification Of Benign Partial Epilepsy Of Childhood With Centrotemporal Spikes, Jessica A. Scarborough 2017 University of San Francisco

The Acquisition And Analysis Of Electroencephalogram Data For The Classification Of Benign Partial Epilepsy Of Childhood With Centrotemporal Spikes, Jessica A. Scarborough

Master's Theses

In this thesis, I will expand upon each step in the process of acquiring and analyzing electroencephalogram (EEG) for the classification of benign childhood epilepsy with centrotemporal spikes. Despite huge advancements in the field of health informatics—natural language processing, machine learning, predictive modeling—there are significant barriers to the access of clinical data. These barriers include information blocking, privacy policy concerns, and a lack of stakeholder support. We will see that these roadblocks are all responsible for stunting biomedical research in some way, including my own experiences in acquiring the data for the second chapter of this thesis.

Ethical Concerns For Assisted Reproductive Technologies, Olga Najera 2017 Abilene Christian University

Ethical Concerns For Assisted Reproductive Technologies, Olga Najera

Dialogue & Nexus

The development of assisted reproductive technologies has provided new options for infertile couples in their pursuit of parenthood. As a result of the successful implementation of in vitro fertilization (IVF), gestational surrogacy is now an alternative. Other technology, such as genetic enhancement, could potentially become available for human beings soon; however, numerous ethical concerns have been raised by the fact that it requires germline engineering. The concerns brought about by these new reproductive technologies will be addressed in light of the teachings of the Roman Catholic Church and of the following ethical theories: Kantian, evolutionary, utilitarian, and virtue ethics.

Controlling The Controls, Arianna T. Schabauer

Honors Theses AY 16/17

Research provides the basis for scientific discovery and advancements in all areas of science. The process of discovery involves countless repetitions of the identical experiment in order to make a claim about the topic in question. In order to properly conduct an experiment that is similar or the same to one already executed, all of the variables must be perfectly controlled. In experiments discussed in this presentation, living conditions involving rats are the variables to control. Some of the variables include lighting, exercise, water intake, and diet.

A current problem facing research is the way diets are being reported in ...


How Neural Activity Shapes Decision Making: An Optogenetic Investigation Of The Neural Basis Of Mate Choice In Female Songbirds, Sarah E. Maze 2017 University of Wyoming

How Neural Activity Shapes Decision Making: An Optogenetic Investigation Of The Neural Basis Of Mate Choice In Female Songbirds, Sarah E. Maze

Honors Theses AY 16/17

The intent of this project is to gain new insight into the neural circuitry that underlies decision making through understanding the connection between sensory perception and motor action. This investigation further seeks to identify whether optogenetic manipulation of specific neurons results in a change in mate choice. In defining this connection, the end goal is to combat deleterious decision making behavior in humans, such as drug addiction. Female Bengalese finches (BFs) provide an accessible model in which to investigate the neural mechanisms of behavior. Previous studies reveal that activity in the caudal portion of the mesopallium (CM) in the female ...

Structure Activity Relationship Studies Of Novel Diarylpentanoid Analogs Targeting The Androgen Receptor In Prostate Cancer Cells, Haili Coffin, Marco Bisoffi 2017 Chapman University

Structure Activity Relationship Studies Of Novel Diarylpentanoid Analogs Targeting The Androgen Receptor In Prostate Cancer Cells, Haili Coffin, Marco Bisoffi

Student Research Day Abstracts and Posters

The development of prostate cancer (PCa) relies strongly on the activation of the androgen receptor (AR) signaling pathway by its natural ligand dihydrotestosterone. Furthermore, PCa progression to metastatic disease represents oncogene addiction to AR activity. Androgen ablation therapy is thus a mainstay therapy against this disease, but the development of ligand-independent AR activation and persisting AR expression eventually leads to castration resistant PCa (CRPC). Therefore, down-regulation of AR expression in PCa cells may be an effective therapeutic modality. The diarylpentanoid ca27 has previously been shown to down-regulate AR expression by an unknown mechanism of action. The present work represents a ...


Vitamin D Supplementation In Allo-Hsct Patients, Bailey Nelson 2017 University of Nebraska Medical Center

Vitamin D Supplementation In Allo-Hsct Patients, Bailey Nelson

Theses & Dissertations

BACKGROUND: Bone health is a serious concern for long-term survivors of Allo-HSCT due to multiple risk factors including steroids, chemotherapy, immunosuppressive drugs, and poor nutrition status1. Steroids have been long proven to have negative impact on bone health and the National Osteoporosis Foundation (NOF) lists steroids as a contributing factor to osteoporosis and fractures. NOF guidelines recommend providing adequate daily vitamin D as a safe and inexpensive way to help reduce fracture risk1. Therefore, proper supplementation of vitamin D may increase the quality of life for patients post Allo-HSCT.

PURPOSE: The purpose of this study is to determine if Allo-HSCT ...


Characterization Of Murine Breast Cancer Cell Lines For Anti-Cancer Vaccine, Haven N. Frazier 2017 University of Arkansas, Fayetteville

Characterization Of Murine Breast Cancer Cell Lines For Anti-Cancer Vaccine, Haven N. Frazier

Biological Sciences Undergraduate Honors Theses

Breast cancer is the most commonly diagnosed cancer in women and the second leading cause of cancer death among women in the United States (1). While treatments involving radiation and chemotherapy currently exist, disease must be detected early in order for the treatments to be somewhat effective, and there is no effective treatment after metastasis occurs (2). Additionally, current therapies do not mitigate tumor immunosuppression. Decreasing the tumor-associated immunosuppressive conditions while activating antitumor immunity could prevent recurrence and metastasis, possibly leading to an effective treatment for cancer (3). Tumor cell vaccines could possibly address this issue and have become a ...

Parp Inhibitor Upregulates Pd-L1 Expression And Enhances Cancer-Associated Immunosuppression, Shiping Jiao

UT GSBS Dissertations and Theses (Open Access)

With recent approvals for therapeutic antibodies that block CTLA4, PD-1 and PD-L1, immune checkpoints have emerged as new targets in cancer therapy. In addition, there is accumulating evidence highlighting the role of cancer-associated immunity in patient response to cytotoxic anticancer agents. Inhibitors of poly (ADP-ribose) polymerase (PARP) have shown substantial cytotoxic effects against tumors with defects in DNA damage responses. However, whether a crosstalk between PARP inhibition and immune checkpoints exists remains unclear. Here, it has been shown that PARP inhibitors (PARPis) upregulate PD-L1 expression in multiple cancer cell lines, human xenograft tumors, and syngeneic mouse tumors. Mechanistically, PARPi inactivates ...

Humor In Medicine: A Literature Review Of Humor’S Potential Therapeutic Value In Health Care, Weston Michael Grant

Psychological Science Undergraduate Honors Theses

Using humor and laughter within the health care field has the potential to be relevant to patients during treatment, to the patient-caregiver relationship, to the subjective well-being of health care providers, and to the environments’ (e.g., work settings) impact on group relationships (e.g., colleagues). A review of the literature examines how the psychological and physiological effects of laughter and humor within the human body impact health and well-being, how humor and laughter improve the patient-practitioner relationship, and if humor and laughter can potentially impact physician burnout. Several possible implications for these findings are discussed, such as professional medical ...


Investigating The Mechanism Of Novel Anticancer Agent, As1411 : Does Metabolism To Guanine Play A Role?, Parker T Howard 2017 University of Louisville

Investigating The Mechanism Of Novel Anticancer Agent, As1411 : Does Metabolism To Guanine Play A Role?, Parker T Howard

College of Arts & Sciences Senior Honors Theses

AS1411 is an oligonucleotide that has shown promising results in lab experiments and clinical trials as an anti-cancer drug, Likewise, treatments with guanine based purine compounds (GBPCs) have demonstrated similar anti-proliferative effects in vitro. This activity is dependent on the HGPRT enzyme. Similarities in activity and physical structure has led us to believe that AS1411 and GBPCs operate by a similar mechanism. To test this, we compare the activity of both in the presence of HGPRT siRNAs and HGPRT deficient cells. While siRNA treatment was unable to alter the activity of GBPCs or AS1411 in our cell lines, HGPRT deficient ...


Investigating The Role Of Dispatched In Hedgehog Ligand Transport And Delivery, William Bodeen 2017 University of Tennessee Health Science Center

Investigating The Role Of Dispatched In Hedgehog Ligand Transport And Delivery, William Bodeen

Theses and Dissertations (ETD)

During the development of all metazoans, the Hedgehog (Hh) signaling pathway provides instructional cues influencing a variety of cellular processes. The pathway ligand, Hh, is dually lipidated by cholesterol and palmitate, which effectively anchors the molecule to the lipid bilayer of the signal producing cell. To complicate the Hh pathway induction process, the Hh ligand is often produced at a significant distance from the cells it influences. Only one known conserved molecule, Dispatched (Disp), can alleviate the membrane tethering imparted by Hh lipidation. Underscoring the importance of Disp protein during development, knockout animals succumb to lethality at E9.5, an ...


Role Of Dendritic Cells In Pathology Of Respiratory Syncytial Virus Infection In Neonates, Bishwas Shrestha 2017 University of Tennessee Health Science Center

Role Of Dendritic Cells In Pathology Of Respiratory Syncytial Virus Infection In Neonates, Bishwas Shrestha

Theses and Dissertations (ETD)

Respiratory syncytial virus (RSV) is one of the leading causes of bronchiolitis in children. We have shown that neonatal mice respond to primary RSV infection with T helper type 2 (Th2) biased immune responses, which are enhanced following reinfection. Dendritic cells (DCs) including myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) play important roles in driving host responses to RSV infection. mDCs present antigens to help Th cells differentiate, and pDCs protect against viral infection through type I interferons (IFNs). Despite data demonstrating importance of mDCs and pDCs in protection against RSV, it has not been studied in an age appropriate ...

Obstacles Associated With Physician Referral Of Patients Into Clinical Trials, Nick Torrez

Theses and Dissertations

Understanding the safety and efficacy of potential new medications relies on evidence gained through the participation of subjects in clinical drug trials. Many clinical trial sites struggle with recruitment of suitable participants which can delay the progress of drug development. Physicians can play a significant role in influencing patients to enter into a clinical trial, however many physicians due not utilize their unique position to facilitate the recruitment of patients into clinical trials, which may help to advance medical science and improve future treatment options. The lack of participation by physicians in the referral of patients into clinical trials (Crosson ...
