Detection Of Myofascial Trigger Points With Ultrasound Imaging And Machine Learning, Benjamin Formby

All Theses

Myofascial Pain Syndrome (MPS) is a common chronic muscle pain disorder that affects a large portion of the global population, seen in 85-93% of patients in specialty pain clinics [10]. MPS is characterized by hard, palpable nodules caused by a stiffened taut band of muscle fibers. These nodules are referred to as Myofascial Trigger Points (MTrPs) and can be classified by two states: active MTrPs (A-MTrPs) and latent MtrPs (L-MTrPs). Treatment for MPS involves massage therapy, acupuncture, and injections or painkillers. Given the subjectivity of patient pain quantification, MPS can often lead to mistreatment or drug misuse. A deterministic way …

Rapid Leaf Senescence Symptoms Are Related To Carbohydrate Depletion In Cut Chrysanthemums, And Strategies For The Symptoms Reduction, Shara Ortiz Carvajal

All Theses

Chrysanthemum (Chrysanthemum ×morifolium) is the second-largest exported cut flower worldwide; however, some cultivars exhibit rapid leaf senescence during their first week of vase life. This phenomenon negatively impacts consumer perception of plant quality, and its cause has been unknown. Experiments were performed in Colombia on cut chrysanthemums shipped to the U.S. for vase-life evaluation. After 10 d, the severity of leaf senescence symptoms was recorded. Experiments examined the effect of flower form [disbud (one flower per stem) versus spray (5-10 flowers per stem)], the effect of time of harvest (A.M. versus P.M.), and sugar sources (dextrose, fructose, mannitol, and sucrose) …

Germination Trends Of American Chaffseed, Schwalbea Americana L., And Factors Affecting First-Year Seedling Development, Trenton Miller

All Theses

Following centuries of exploitation and fire suppression, longleaf pine systems are now the focus of many conservation efforts. Efforts to restore populations of Schwalbea americana L. in longleaf pine savannas have been met with frustratingly low recruitment. While past studies have briefly quantified germination rates for Schwalbea, there have not been any studies yet that truly investigate this plant’s germination requirements. Additionally, there has been little research into characterizing the parasitic relationship between Schwalbea and its various host species. We conducted a germination study in a growth chamber that investigated Schwalbea’s germination rate and time to germinates as …

An Empirical Examination Of Consequential Factors Of Negative Program Culture As Determinants Of Affective Well-Being In Graduate Students, Morgan Chandler

All Theses

There is evidence of a crisis of low affective well-being troubling graduate students nationwide. Recent studies have shown that graduate students exhibit indicators of low affective well-being, such as levels of anxiety and depression six times greater than the general population (Galleo et al., 2021; Glover, 2019), high levels of being overwhelmed (Kaler & Stebleton, 2019), and overall increased psychological distress (Hacker, 2021). The prevalence and severity of these issues indicate that their causes may exceed personal factors (Bekkouche et al., 2022). Previous research has identified the quality of culture and culture-related factors within graduate schools and programs to be …

Medical Simulation-Based Sensor Methods For Ultrasound-Guided Dialysis Cannulation Skill Assessment, Devansh Shukla

All Theses

End-stage kidney disease (EKSD) is the final, permanent stage of chronic kidney disease (CKD), where the body's kidneys cannot filter blood sufficiently. Hemodialysis treats ESKD by filtering wastes and water from your blood externally via a dialyzer. Patients on hemodialysis require a vascular access, typically an arteriovenous fistula (AVF) or arteriovenous graft (AVG) for dialysis, which is used three times a week for about four hours a session. These life-saving therapies can be quite tedious, especially for elderly patients and patients with co-morbidities. As such, successful cannulation is extremely important to ensure the longevity of the patient's vascular access and …

Elucidation Of The Role Of Avocado Wri1 And Wri2 And Their Ability To Affect Oil Content And Composition When Co-Expressed With Pdat1 And Dgat1, Jyoti Ranjan Behera

Electronic Theses and Dissertations

Plants synthesize and store oil, mostly as triacylglycerols (TAG), in seeds that is transcriptionally controlled by WRINKLED1 (WRI1), an APETALA2 (AP2) transcription factor. Among the four Arabidopsis WRI paralogs, WRI2 is nonfunctional, while the others are expressed in a tissue-specific manner. Additionally, two rate-limiting enzymes, diacylglycerol acyltransferase (DGAT) and phospholipid diacylglycerol acyltransferase (PDAT) catalyze the terminal step in TAG assembly and contribute to oil accumulation. Avocado (Persea americana) mesocarp, a non-seed tissue, accumulates significant amounts of TAG (~70% by dry weight) enriched with heart-healthy oleic acid. The oil accumulation stages in mesocarp coincide with the high expression of …
