Predictive Ability Of A 3d Body Scanning Mobile Application For Metabolic Health Risk, Caleb Brandner
Predictive Ability Of A 3d Body Scanning Mobile Application For Metabolic Health Risk, Caleb Brandner
Master's Theses
There is an increasing prevalence of obesity within the US and rising rates of metabolic syndrome among those aged 20-39 concurrent with a decrease in the reception of primary care. Limitations to healthcare including access, cost, and availability, highlighting the need for simple, efficient, and accessible cardiometabolic health risk screening. Given the surge in smartphone ownership over the last decade, this study sought to determine the predictive ability of a mobile 3D-optical (3DO) body composition assessment application in determining metabolic health risk. A total of 62 participants (female: 36) underwent traditional anthropometric measurements, 3DO body scanning using a smartphone application, …
Acute Cardiovascular Response To Low-Load Unilateral, Bilateral, And Alternating Resistance Exercise With Blood Flow Restriction In The Lower Body, Daphney Stanford
Acute Cardiovascular Response To Low-Load Unilateral, Bilateral, And Alternating Resistance Exercise With Blood Flow Restriction In The Lower Body, Daphney Stanford
Master's Theses
Resistance exercise with blood flow restriction (BFR) has been suggested to exaggerate the exercise pressor response over traditional non-BFR exercise. While applying BFR relative to an individual’s arterial occlusion pressure (AOP) and exercising at low-loads seems to produce a comparable cardiovascular response to traditional moderate or high-load training, it is beneficial to identify modifications for reducing the cardiovascular response to BFR exercise. PURPOSE: To determine if unilateral (UNI), bilateral (BI), or alternating (ALT) exercise modalities elicit different cardiovascular responses during BFR exercise. METHODS: 18 participants (13 male and 5 female) performed four sets of UNI, BI, and ALT knee-extensions at …
Self-Assembled Gold Nanoplexes For Cancer-Targeted Sirna Delivery, Yongliang Shi
Self-Assembled Gold Nanoplexes For Cancer-Targeted Sirna Delivery, Yongliang Shi
Master's Theses
Through layer-by-layer method, the authors have constructed three Au nanoplexes: AuPEI/RNA/PEI, AuPEI/RNA/PEI-mPEG, and AuPEI/NA/PEI-PEG-FA. All the nanoplexes are characterized by UV-vis spectrometry, DLS, and zeta potential. The surface density of the first layer PEI and second layer RNA were also determined. Moreover, the Au nanoplexes can protect siRNA from RNase degradation and are stable in cell culture medium.
siGLuc-ppp, ssRNA80, and siF17 were delivered by the assembled Au nanoplexes, and the results were analyzed by GLuc assay, TB assay, and Luciferase assay. In terms of RNA delivery, the Au nanoplexes AuPEI/RNA/PEI exhibited excellent gene silencing efficiency (or causing …
Propagation Of Oligomeric Α-Synuclein And Amyloid-Β: Implications For Parkinson's And Alzheimer's Diseases, Matthew Stephen Planchard
Propagation Of Oligomeric Α-Synuclein And Amyloid-Β: Implications For Parkinson's And Alzheimer's Diseases, Matthew Stephen Planchard
Master's Theses
The aggregation of amyloidogenic proteins is a critical event in the pathology of a variety of neurodegenerative diseases, including Alzheimer’s disease (AD) and Parkinson’s disease (PD). The proteins α-synuclein (αS) and amyloid-β (Aβ) are involved in the formation of amyloid lesions observed in PD and AD, respectively. Both PD and AD exhibit a significant amount of co-pathology in clinical settings, and the αS and Aβ proteins have been shown to interact in vitro. Recent experimental consensus has shown oligomeric species to be significant, if not primary, sources of toxicity in these diseases. …
An Insight Into The Microbial Diversity And Expression Of Cysteine Protease Inhibitors (Cystatin) In Rickettsia Parkeri Infected Amblyomma Maculatum, Khemraj Budachetri
An Insight Into The Microbial Diversity And Expression Of Cysteine Protease Inhibitors (Cystatin) In Rickettsia Parkeri Infected Amblyomma Maculatum, Khemraj Budachetri
Master's Theses
Amblyomma maculatum (Gulf Coast tick) is an emerging tick species of public health significance in United States. It is a competent vector of Rickettsia parkeri, an etiological agent of a human rickettsiosis. In this study, we investigated the spotted fever group of rickettsial diversity in A. maculatum based on rickettsial ompA gene PCR. Our results showed A. maculatum harbors R. parkeri, R. amblyommii, and R. endosymbiont of A. maculatum. While only R. parkeri was detected in female salivary glands which suggest its ability to traffic from midgut to salivary glands via hemocoel. The presence of R. parkeri was further …
A Formative Evaluation For A Food Choices Intervention In A Mississippi Delta Community: A Focus Group Of Rural African American Adolescents, Jovan Chantrell Eugene Williams
A Formative Evaluation For A Food Choices Intervention In A Mississippi Delta Community: A Focus Group Of Rural African American Adolescents, Jovan Chantrell Eugene Williams
Master's Theses
A needs assessment should be conducted to plan effective interventions. This study used a qualitative research approach to examine the eating patterns, food purchasing and preparation skills and practices, barriers and facilitators of dietary change, social and contextual influences on food choices, and preferences for communication and presentation channels and styles of low-income rural African American adolescents. Seven focus groups were conducted with a total of 33 participants, 21 girls and 12 boys, aged 13-18. Adolescents were grouped by age and gender. A moderator, who was trained in focus group methodology, conducted the session using a focus group discussion guide …
