Description

Abstract Text:
PI: Freeman, J., Brolinson, G. and Rylander, N.
Proposal Number: 1034026

Sprains and strains account for 5.7 million visits to emergency rooms in the United States each year. A strain is an injury to the muscle or tendon due to overuse or trauma. An estimated 200,000 Americans required reconstructive surgery of ligaments alone in 2002 with a price tag exceeding five billion dollars. There are approximately 61,000 people in the United States affected by Ehlers-Danlos Syndrome (EDS), a connective tissue disorder. EDS, causes the body to produce faulty and weak collagen. While there are several types of EDS, a common trait is hypermobile and unstable joints. People with EDS experience frequent joint dislocations and subluxations which are painful and debilitating. Effectively, these are continual sprains and strains, patients would greatly benefit from a permanent form of internal bracing and stabilization of the joints.
Prolotherapy is an available, but somewhat controversial, treatment for damaged and painful ligaments and tendons. It involves the injection of a proliferant solution into the tendon or bone-ligament junction, stimulating the body's wound healing cascade. The damaged tissue is repaired, and new collagen is laid down which gradually shrinks, forming a denser, stronger, and tighter ligament or tendon. In persons with normal collagen production the repair is long term. Those with EDS usually need ongoing treatment.
In order to enhance the effectiveness and prolong the results of prolotherapy (possibly making it a permanent solution) we propose the use of prolotherapy with carbon nanostructures, carbon nanotubes (CNTs) or carbon nanohorns (CNHs). This transformative treatment would retain all of the benefits of normal prolotherapy while providing immediate mechanical reinforcement (due to nanostructuress) and long term agitation of fibroblasts by nanostructures for the production of collagen if the joint is loose at a later date (as a result of injury or EDS). We propose to investigate this therapy through the following objectives: 1) Testing prolotherapy solutions, nanostructures, and anesthesia commonly used in prolotherapy with fibroblasts. This will insure that we find a combination of these agents that causes the least cell damage, produces the most collagen and does not lead to nanostructure ingestion by the cells. 2) Injecting different concentrations of nanostructures into excised ligaments to view the optimal concentration for improved mechanical properties. 3) The use of the best prolotherapy solution and types and concentration of nanostructures in a rabbit strained MCL model. This model will test the effectiveness of the new therapy
Intellectual Merit: This enhanced prolotherapy treatment has the potential to quickly and effectively treat strains, sprains, and tissues weakened by genetic disorders. The use of carbon nanostructures to immediately enhance tissue stiffness and promote the growth of new collagen over the long term makes this treatment immediately effective in restoring tissue mechanical properties and drastically reduces the chances of injury recurrence. The later point is of extreme importance to people with EDS because they may undergo hundreds to thousands of treatments over a lifetime.
Broader Impact: This proposed research will enhance the treatment of sprained and strained tissues along with injuries due to connective tissue disorders, such as EDS. It has the possibility of expanding the use of new therapeutic agents in sports medicine allowing athletes to return from injury quicker and less prone to repeat the injury. This research will provide an opportunity for students to gain experience in experimental design, engineering, and cell biology at the graduate, undergraduate, and high school levels. Dr. Joseph Freeman as an African American and Dr. Nichole Rylander as a female represent underrepresented groups within the biomedical engineering field and are devoted to establishing outreach programs to recruit underrepresented students (minorities and women) into the field. They are involved with several advancement organizations including AdvanceVT (female recruiting program) and Center for the Enhancement of Engineering Diversity (CEED) at Virginia Tech. Undergraduate and graduate students will be recruited from these programs to conduct research related to this project during the academic year and summer. Two scholastically strong undergraduate students from underrepresented groups will be recruited to perform summer research for 10 weeks through the Bioengineering and Bioinformatics Summer Institute (BBSI) program at Virginia Tech. In addition, a graduate student with EDS will perform the research described here as part of her Master's Thesis.

It is important to recognize, and consider in any interpretation of Federal RePORTER data, that the publication and patent information cannot be associated with any particular year of a research project. The lag between research being conducted and the availability of its results in a publication or patent award varies substantially. For that reason, it's difficult, if not impossible, to associate a publication or patent with any specific year of the project. Likewise, it is not possible to associate a publication or patent with any particular supplement to a research project or a particular subproject of a multi-project grant.
