The Effect Of Fascicular Elastin On The Mechanical And Functional Properties Of Healthy, Damaged, And Healing Tendon, Shawn Pavey

McKelvey School of Engineering Graduate Student Theses & Dissertations

Mechanical properties of tendon are highly influenced by structural protein composition and microscopic sub-structures. Within the largest subunit of tendon, the fascicle, the role of the elastin protein remains understudied despite impressive extensibility and fatigue resistance of its resulting elastic fibers. While previous work catalogued contributions of fascicular elastin across tendon type and species, the anticipated effects of elastin in fatigue and healing have not yet been explored. While previous knockout mouse models showed that disruption of elastic fibers led to altered mechanical properties (e.g., increased linear modulus), these models depended on heterozygous elastin deficiency or indirect knockout of proteins …

Design Of Non-Invasive Device To Measure Differential Flow In The Carotid Arteries, Rachel Elisabeth Jacquay

Masters Theses

A stroke is categorized as quickly developing symptoms of cerebral function loss with no apparent cause other than that of vascular origin. Stroke detection in prehospital settings, such as an ambulance, is subjective and often requires additional imaging methods to obtain a definitive conclusion. Common non-invasive methods for stroke detection include Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans. Still, these techniques can be expensive, time-consuming, and dangerous due to exposure to strong magnetic fields and radiation. Two additional methods have been proposed for quick, inexpensive, and non-invasive stroke detection, namely Ultrasound Doppler and Pressure Transducer. A simplified physical …
