Family Medicine

• The United States is currently experiencing an opioid epidemic, which claims 115 lives daily by overdose.
• Tools for identifying patients at increased risk for abuse include: Screener and Opioid Assessment for Patients with Pain (SOAPP-R) and Opioid Risk Tool (ORT).
• However, data is lacking for the comparison of the two most commonly used opioid screen tools (SOAPP-R and ORT).
• We are comparing the effectiveness of these screening tools for patients being discharged from the hospital who have no "red flags" for abuse.

Chemical Epitope Targeting: Review Of A Novel Screening Technology, Qurrat Ul-Ain, Rene Kandler, Dylan Gillespie, Arundhati Nag

Scholarly Undergraduate Research Journal at Clark (SURJ)

Chemical Epitope Targeting is a novel technology developed for designing peptide ligands with high affinity and specificity against specific regions of a protein that may be inaccessible to small molecules or antibodies. In this review, we summarize the key steps and significant applications of this technology. Operating on the same principles as antibody-antigen interactions, this technique involves chemically synthesizing the region of interest on the protein, called the epitope, as a polypeptide with a biotin detection tag and a strategically placed alkyne or azide presenting amino acid. The constructed epitope is screened against a comprehensive linear or cyclic One Bead …

Developing A Dissociative Nanocontainer For Peptide Drug Delivery, Michael Patrick Kelly

Dissertations, Theses, and Capstone Projects

The potency and specificity of bioactive peptides have propelled these agents to the forefront of pharmacological research. However, delivery of peptides to their molecular target in cells is a major obstacle to their widespread application. A Trojan Horse strategy of packaging a bioactive peptide within a modified protein cage to protect it during transport, and releasing it at the target site, is a promising delivery method. Recent work has demonstrated that the viral capsid of the P22 bacteriophage can be loaded with an arbitrary, genetically-encoded peptide, and externally decorated with a cell-penetrating peptide, such as HIV-Tat, to translocate across in …

Assessing Workplace Wellness For The Occupation Of Hairdressing, Alex Kim

Student Capstone Papers

There is presently a lack of occupational therapy interventions that holistically treat work-related musculoskeletal disorders (WRMSDs) commonly found in the hairdressing population. Current studies found in the literature solely focus on the hairdressers’ symptoms, which leads to a more limited understanding of their situation. Furthermore, this focus on symptoms could lead to the possibility of overlooking confounding variables that could play a role in impacting these workers. This capstone project aims to examine the hairdressing occupation as a whole, assessing the health-related needs of hairdressers and create a holistic program that would address current needs and future preventative treatments for …

Predicting Premature Birth Risk With Cfrna, Jason Lin, Jonathan Marin, John Santerre

SMU Data Science Review

Identifying which genes are early indicators for preterm births using cell-free ribonucleic acid (cfRNA) from non-invasive blood tests provided by pregnant women can improve prenatal care. Currently, there are no medical tests for early detection of preterm birth risk in routine checkups for pregnant women. Recent studies have shown potential genes that can predict preterm birth. Machine learning techniques are utilized to see if the Area Under the Curve (AUC) can be improved upon when evaluating the prediction accuracy for chosen genes sequences and concentrations. Using cell-free RNA data from non-invasive blood tests in conjunction with machine learning, we improve …

Development Of A Screening Method For Drugs Of Abuse By Direct Analysis Of Dried Urine Spots Coupled To Mass Spectrometry, Melanie Goldstein

Student Theses

Fast and easy screening procedures are essential in any forensic toxicology laboratory to differentiate negative samples from presumptive positive cases. Immunoassay techniques, such as enzyme multiplied immunoassay technique (EMIT), are routinely employed as screening procedures. However, these techniques lack specificity (only differentiate group of drugs and not individual compounds) and it is difficult to add new compounds to the panel. Direct analysis of dried urine spots (DUS) by mass spectrometry (MS) offers a novel strategy to overcome these issues. DUS offer an improved storage alternative for biological samples, reducing costs and space requirements. In this work, an original method to …

Deep Learning-Based Structure-Activity Relationship Modeling For Multi-Category Toxicity Classification: A Case Study Of 10k Tox21 Chemicals With High-Throughput Cell-Based Androgen Receptor Bioassay Data, Gabriel Idakwo, Sundar Thangapandian, Joseph Luttrell Iv, Zhaoxian Zhou, Chaoyang Zhang, Ping Gong

Faculty Publications

Deep learning (DL) has attracted the attention of computational toxicologists as it offers a potentially greater power for in silico predictive toxicology than existing shallow learning algorithms. However, contradicting reports have been documented. To further explore the advantages of DL over shallow learning, we conducted this case study using two cell-based androgen receptor (AR) activity datasets with 10K chemicals generated from the Tox21 program. A nested double-loop cross-validation approach was adopted along with a stratified sampling strategy for partitioning chemicals of multiple AR activity classes (i.e., agonist, antagonist, inactive, and inconclusive) at the same distribution rates amongst the training, validation …

Non-Viral Transfection Efficiencies For The Advancement Of Car-T Therapy., Emily M Murphy

Electronic Theses and Dissertations

Leukemias are the most common form of childhood cancer making up 30% of total pediatric oncological cases, and Acute Lymphoblastic Leukemia (ALL) makes up a significant portion (12%) of the total pediatric cancer diagnoses. In 2017, the FDA approved a successful immunotherapy called CAR-T therapy for the treatment of pediatric B-cell ALL. This therapy includes a CAR (chimeric antigen receptor) that is loaded into the T-cell and expressed. Currently, the loading of the CAR utilizes viral transduction, but consistency issues lead to adverse symptoms in the patients. Better methods of transduction/transfection are being studied in order to improve these consistency …
