Improving The Palatability Of Colonoscopy Preparations, Phuong Anh Hoang Nguyen, Darnell Leon Cuylear, Heather Elizabeth Canavan Nov 2018

Improving The Palatability Of Colonoscopy Preparations, Phuong Anh Hoang Nguyen, Darnell Leon Cuylear, Heather Elizabeth Canavan

Shared Knowledge Conference

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. The most reliable screening method of CRC is a colonoscopy which requires a 4-Liter polymer with electrolytes preparation. Two in five patients are non-compliant to their colonoscopy schedules, with many patients who abstain reporting refusal due to significant discomfort associated with this preparation. Furthermore, there are distinct gender differences in the tolerance of colonoscopy preparations in male and female populations. We hypothesize the differences in clinic are a result of toxic effects of the drug associated with poor mixing by individual patients. PEG, the drug, …


An Engineer’S Take On The Bone-Ligament Interface: Utilizing Novel Technology To Improve Clinical Outcomes, Emma Garcia Nov 2018

An Engineer’S Take On The Bone-Ligament Interface: Utilizing Novel Technology To Improve Clinical Outcomes, Emma Garcia

Shared Knowledge Conference

Ligament repair is a common surgical practice with a significant lack of viable replacements. The current gold standard for repair is the use of tendon grafts from cadavers or from another place in the patient’s body; however, these often cause more problems than they solve including immune responses or a lack of mobility in another place in the body. Synthetic replacements are of growing interest, though the ability to mimic the complex structure of the ligament and how it connects to the bone remains an obstacle. Our lab built a 3D bioprinter combined with an electrospinner to address this complicated …


Computational Investigation Of The Interactions Between Bioactive Compounds And Biological Assemblies, Tye D. Martin Nov 2018

Computational Investigation Of The Interactions Between Bioactive Compounds And Biological Assemblies, Tye D. Martin

Shared Knowledge Conference

Design of small molecules is an ongoing focus for developing agents against pathogenic viruses and bacteria that are threats to worldwide health. Viruses such as Zika feature assemblies of repeat peptide subunits or capsid proteins which are potential targets for antiviral compounds. Other protein assemblies are implicated in pathology of Alzheimer’s Disease (AD) and additional neurodegenerative diseases characterized by large assemblies of misfolded proteins such as amyloid-beta (Aβ) and tau. Recent studies on a class of conjugated polyelectrolytes (CPEs) with phenylene ethynylene moieties and charged functional groups have shown potential both as bioactive antimicrobials and theragnostic sensing agents for tracking …

3d Bioprinting And Near-Field Electrospinning Composite Scaffolds For The Bone-Ligament Interface, Emma Garcia, Christina Salas, Matthew N. Rush, Christopher Buksa, Marissa Perez, Ava Mauser, Steven Nery, Fermin Prieto, Darielys Morales Nov 2018

3d Bioprinting And Near-Field Electrospinning Composite Scaffolds For The Bone-Ligament Interface, Emma Garcia, Christina Salas, Matthew N. Rush, Christopher Buksa, Marissa Perez, Ava Mauser, Steven Nery, Fermin Prieto, Darielys Morales

Shared Knowledge Conference

3D bioprinting is an additive manufacturing technique that can utilize a range of bioactive materials to construct specific architectures that mimic native tissue. Near-field electrospinning (NFE) offers precise alignment control to create non-woven mats with high tensile strengths. We built a custom E-spin printer that enables layer-by-layer alternating deposition between 3D bioprinting and NFE to create composite scaffolds for the bone-ligament interface. This complex region is difficult to simulate due to its functionally graded mechanical and biochemical properties. We created NFE poly(caprolactone) highly aligned micro-fibers which formed collagen fibril-like bundles. Poly(ethylene glycol) diacrylate with decellularized bone was encased in the …

The Summer Undergraduate Research Fellowship (SURF) Symposium

The common yeast infection, vulvovaginal candidiasis, affects three out of four women throughout their lifetime and can be spread to their child in the form of oral candidiasis (thrush). This disease is caused by the fungal pathogen Candida albicans, which is also a major cause of systemic candidiasis, a rarer but deadly disease with up to a 49% lethality rate. Current widely-used diagnostic methods include cell cultures, pH tests, and antibody detection, to assist effective treatment. Despite availability of various diagnostic methods, there is no inexpensive, rapid, and accurate way to detect C. albicans infection. This project aims to …


Tissue Clearing As A Mechanism To Identify Changes In Fibronectin Structure During Breast Cancer Metastasis, Maryam Nuru, Kelsey Hopkins, Luis Solorio Aug 2018

Tissue Clearing As A Mechanism To Identify Changes In Fibronectin Structure During Breast Cancer Metastasis, Maryam Nuru, Kelsey Hopkins, Luis Solorio

The Summer Undergraduate Research Fellowship (SURF) Symposium

With metastasis accounting for approximately 90% of breast cancer deaths and an alarming number of over 300,000 new breast cancer cases to be diagnosed by the end of 2018, there is growing need to understand the process of breast cancer. Changes in the extracellular matrix (ECM) of the tumor microenvironment play an essential role in this deadly tumor progression. Specifically, the glycoprotein fibronectin (FN), has been identified to be up-regulated in patients with worse clinical outcomes. During tumor progression fibronectin undergoes conformational changes that aid in metastatic dissemination. In order to analyze the dynamic changes in FN expression and evaluate …

3d Printed Pla Scaffolds To Promote Healing Of Large Bone Defects, Jacob W. Cole, Tiera Martinelli, Mitchell T. Ryan, Sarah G. Seman, Daniel Sidle, Stephen R. Smith, Rocco J. Rotello, Timothy L. Norman

The Research and Scholarship Symposium (2013-2019)

One challenge modern medicine faces is the ability to repair large bone defects and stimulate healing. Small defects typically heal naturally, but large bone defects do not and current solutions are to replace the missing tissue with biologically inert materials such as titanium. This limits the amount of bone healing as the defect is not repaired but rather replaced. The focus of our research is to develop a method of using 3D printing to create biodegradable scaffolds which promote bone in-growth and replacement. To accomplish this we used poly lactic acid (PLA) filament and a desktop 3D printer. To promote …
