The Sub-Chronic Vascular Response To Water-Borne Embolic Coacervates., Joshua P. Jones, Monika Sima, Russell J. Stewart

Biomedical Engineering Western Regional Conference

Water-borne coacervates that solidify in response to decreasing ionic strength have been developed as an agent for small vessel transcatheter embolization. Here, the sub-chronic vascular response to these agents will be presented. Embolic coacervates demonstrated a benign foreign body response, which supported tissue ingrowth and stabilized vessel occlusion out to 28 days. As with other liquid embolics, occlusion is dependent upon mechanical obstruction of the vessel and native thrombus. Over time, the thrombus becomes more organized by fibroblasts. Continuation of the processes seen at 28 days will likely result in fibrous encapsulation of the embolic coacervate, further stabilizing the occlusion.

Simulation Of Tremor Propagation In The Upper Limb, Thomas Corie, Steven K. Charles Dr

Biomedical Engineering Western Regional Conference

Essential tremor (ET) is the most common movement disorder and is estimated to affect between 1 and 12 million people in the US. Our long-term goal is to develop effective wearable tremor-suppressing devices. To reach this goal, we must first understand how tremor propagates from its mechanical origin (muscle) to the hand, where it matters most. The purpose of the current work is to characterize the extent to which tremor in different muscles or muscle groups contributes to tremor at the hand.

Differentiation And Containment Of Derived Pancreatic Beta Cells, Caden Duffy, Alonzo Cook Ph.D.

Biomedical Engineering Western Regional Conference

Currently, the only permanent cure for Type 1 Diabetes is a pancreatic or islet transplant. With the shortage of donors, we are progressing research towards alternative therapies by differentiating induced pluripotent stem cells into derived pancreatic β-cells that can be transplanted and used as treatment for Type 1 Diabetes. We are investigating methods to increase the yield of fully derived, insulin producing pancreatic β-cells and are additionally researching the use of hydrophilized expanded polytetrafluoroethylene for use in cell containment devices. These devices could offer a future alternative for islet transplantation in human patients.

Despite modern technology and developments in heart disease treatment and prevention, heart disease remains the number one cause of death in America. With an inability to meet an ever-increasing demand for heart transplants and the dangers of immunosuppressant drugs, any potential alternative to cardiac transplantation must be pursued. The end goal of this research is to engineer biocompatible tissues that are fully functional to repair or replace damaged portions of the heart following the loss of cardiac function. This research investigates the effect of porcine extracellular matrix as the scaffold for beating IPS-differentiated cardiomyocytes.

Computational Characterization Of Blood Vessel Strain In Wire Myography, Sameer S. Nandikar, M Converse, K L. Monson

Biomedical Engineering Western Regional Conference

Blood vessels, and the mechanical forces that act on them, play a key role in both health and disease. As a consequence, the mechanical properties of vessels have been under study for over a century. A variety of approaches have been used to define vessel properties, including stretching of vessel rings to study circumferential behavior, a configuration commonly used in wire myography. The objective of the present study was to develop a finite element model to quantify strains throughout a vessel ring during such loading.

A Nanocomposite Sensor Neck Sleeve For Tracking In Vivo Spine Kinematics In The Alpaca, Colton Porter Graham, Anton Bowden

Biomedical Engineering Western Regional Conference

Chronic low back pain in the US is often attributed to intervertebral disc degeneration. Camelids, particularly alpacas, pose a potential model for spinal treatment due to similarity of the spinal structure and vertical loading. Alpacas also exhibit a high rate of natural disc degeneration. To gain more understanding about how disc degeneration is caused in alpacas it is necessary to understand the loading and motion of the alpaca cervical spine. The goal of the present work was to incorporate nanocomposite sensors into a custom-designed neck sleeve to track the daily in-vivo neck motion of an alpaca in its natural environment.

Using Optimization To Determine Tremor Propagation, Paul Curtis, Steven K. Charles

Biomedical Engineering Western Regional Conference

: Essential Tremor (ET) is one of the most common movement disorders, with millions affected in the US. Currently there are two main treatment options: medication and deep brain stimulation (DBS). Available medications are only 50% effective, and in only 50% of patients, and many patients consider DBS too invasive. The purpose of our research is to determine the origin and propagation of tremor throughout the upper limb.

Analysis Of Magnetic Resonance Imaging Of Peripheral Nerve Regeneration, Jaron J. Lundwall, Alonzo Cook

Biomedical Engineering Western Regional Conference

Due to accident related neural damage, many people’s lives are impaired or limited in what they can do. Current medical practices are limited at helping distal and proximal nerve stubs regenerate. Many recent research studies have focused on trying to improve this problem by understanding how cut or crushed nerves heal. Our study hopes to help these efforts by improving non-invasive analysis techniques of nerve growth. Magnetic Resonance Imaging (MRI) is one possible solution to creating a reliable analysis technique that in the future could be used on humans. However, current methods of taking MRI scans involve toxic resolving fluid …

Developing A Renal Cell Carcinoma Kidney-Tumor-On-A-Chip To Mimic Tumor-Induced Angiogenesis, Connor Tsuchida, Chris Miller, Ying Zheng

Biomedical Engineering Western Regional Conference

Currently, models for testing developing cancer therapeutics are inaccurate. To address this issue, the Zheng Lab is developing a kidney-tumor-on-a-chip to mimic tumor-induced angiogenesis. Initial steps were taken toward this ultimate goal by creating an in vitro study between human kidney microvascular endothelial cells and renal cell carcinoma spheroids. The experiments showed an increase in endothelial sprouts in the presence of renal cell carcinoma spheroids vs. normal kidney cortex spheroids.

T1, T2, And Off-Resonance Mapping Using A Non-Linear Least-Squares Fit Of The Bssfp Signal, Meredith Taylor, Joseph Valentine, Steven Whitaker, Neal Bangerter

Biomedical Engineering Western Regional Conference

The mapping of MR relaxation times has found a broad variety of applications in the study of disease. Unfortunately, the gold standards for acquiring T₁ and T₂ maps require long scan times, and are therefore more suited to 2D acquisitions with limited slices. For reasonable scan times, resolution is limited making these scans less useful for showing fine morphological detail. A rapid 3D sequence at higher resolutions that could be used to provide both morphological detail and relaxation time maps would be particularly useful. We propose a technique with potential to provide simultaneous band-free 3D datasets and estimates …
