The Effect Of Radial And Ulnar Length Change On Distal Forearm Loading, Ahaoiza D. Isa 2017 The University of Western Ontario

The Effect Of Radial And Ulnar Length Change On Distal Forearm Loading, Ahaoiza D. Isa

Electronic Thesis and Dissertation Repository

The effect of distal radial and ulnar length change on forearm bone loading is not well understood during simulated dynamic wrist loading. This thesis presents two studies which investigate the effect of these length changes on distal forearm loading under simulated dynamic wrist motion. The first study investigates the effect of radial length change on axial loading at the distal radius and ulna and relationship between ulnar variance and distal forearm loading. The complex variation in axial loads in the distal radius and during length change and dynamic wrist motion were studied and discussed. There was no correlation between native ...


Acoustic Analysis Of Vocalizations For Detecting Separation Anxiety In Dogs, Karina Sequera, Nan Kong, Niwako Ogata 2017 Florida International University

Acoustic Analysis Of Vocalizations For Detecting Separation Anxiety In Dogs, Karina Sequera, Nan Kong, Niwako Ogata

The Summer Undergraduate Research Fellowship (SURF) Symposium

Separation anxiety in dogs is a clinical condition in which a dog develops an intense dependence on their caretaker. It manifests itself in maladaptive physical and psychological behaviors that are similar to that of panic attacks in humans when the dog is isolated from its owner. These include excessive vocalizations, destructive behaviors, and in more extreme cases, self-mutilation. Currently, there are no direct ways to diagnose separation anxiety without the aid an owner’s report. To ease this diagnostic process, it would be useful to utilize a tool that can distinguish between certain vocalization patterns in dogs. Literature suggests that ...


A Parametric Study Of The Mechanics Of Different Skin Flap Techniques, Steven J. Meza, Adrián Tepole Buganza 2017 California State University, Northridge

A Parametric Study Of The Mechanics Of Different Skin Flap Techniques, Steven J. Meza, Adrián Tepole Buganza

The Summer Undergraduate Research Fellowship (SURF) Symposium

In modern day plastic and reconstructive surgeries numerous skin flap designs have been developed and are used to close open wounds. Skin flaps are developed with the intention of imposing minimal tension in skin closure. Excessive tension can lead to poor blood flow that result in post-surgery complications such as necrosis. Currently there is no standard in choosing a skin flap design and a surgeon's choice is based personal experience. A comparison of the mechanical loading in these various designs has not yet been done. We have developed a parametric study, using finite element analysis, of two advancement skin ...

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 ...


Design And Validation Of An In Vivo Long-Term Attachment Capsule Robot, Wanchuan Xie 2017 University of Nebraska-Lincoln

Design And Validation Of An In Vivo Long-Term Attachment Capsule Robot, Wanchuan Xie

Mechanical (and Materials) Engineering -- Dissertations, Theses, and Student Research

The invention of capsule endoscopy (CE) made the non-invasive monitoring of the entire small bowel possible and became the primary means for diagnosing small bowel pathology. In the last decade, capsule robots have been transformed from diagnostic devices into a widely studied biomedical platform with the potential for active locomotion, drug delivery and therapeutic capabilities. To perform accurate on-site drug release and therapy, it is necessary for a capsule robot to be able to attach to the intestinal tissue and maintain its position long-term. Design challenges derive from the task of long-term mucosal adhesion which requires firm, quick-response attachment without ...

Chemical And Physical Priming Of Human Mesenchymal Stem Cells To Alter Nonviral Gene Delivery Outcomes, Tyler Kozisek, Andrew Hamann, Amy Mantz, Mathias Schubert, Eva Schubert, Angela K. Pannier

Biological Systems Engineering--Dissertations, Theses, and Student Research

Human Mesenchymal Stem Cells: Human mesenchymal stem cells (hMSCs) are a multipotent cell, meaning they are able to differentiate into a more mature cell type, such as osteocytes, chondrocytes, and adipocytes, that are found in numerous tissues in the human body, such as bone marrow, fat, and muscle. Since hMSCs can be derived from adult human tissues, they do not have the same ethical concern associated with them as other stem cells, such as embryonic stem cells. Due to hMSCs multipotency and ease of obtaining, they have become one of the most widely researched stem cell types in areas such ...

Acl Reconstruction Results In Alterations For Force Control Variability During Multidirectional Force Production, Amelia S. Lanier 2017 University of Nebraska at Omaha

Acl Reconstruction Results In Alterations For Force Control Variability During Multidirectional Force Production, Amelia S. Lanier

Student Research and Creative Activity Fair

After anterior cruciate ligament (ACL) rupture most will undergo reconstructive surgery. Within the first year after surgery 25% of patients will re-tear their ACL. Most of those injured attempt to return to sports which include running and cutting. The ability to produce appropriate ground reaction forces may be crucial for the successful return to sports without re-injury. Understanding stability of multidirectional ground reaction force (mGRF) production in healthy and ACL reconstructed (ACL-r) patients can lend insight to the high instance of re-injury. Typically, stability has been measured using linear analyses, but these analyses cannot capture the subtle time varying changes ...

A Nanocomposite Sensor Neck Sleeve For Tracking In Vivo Spine Kinematics In The Alpaca, Colton Porter Graham, Anton Bowden 2017 Brigham Young University

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.

Towards A Bioselective Surface For Treatment Of Sepsis In A Hemoperfusion Device, Karl F. Schilke, Ramya Raman, Bonan Yu, Erik Hahn, Jonathan Su

Biomedical Engineering Western Regional Conference

Sepsis is a dysregulated immune response to circulating bacteria/endotoxin. Hemoperfusion is a promising treatment, but is not universally effective and can unacceptable blood damage. We are developing protein-repellent hydrogel nanofilms that can be grown on a variety of surfaces, and functionalized with “click-ready” pathogen-binding proteins expressed by Genetic Code Expansion (GCE). The extremely rapid, bioorthogonal “click” immobilization chemistry eliminates prior purification, maximizes surface loading, and guarantees spatial orientation of the immobilized proteins. We have demonstrated pathogen binding and blood protein repulsion by these layers, suggesting that they may be part of effective treatments for sepsis and other applications.
