Validity Of A Nutrition Knowledge Questionnaire For Adults With Intellectual Disability, Brooke Marie Bouza

International Journal of Exercise Science: Conference Proceedings

Nutrition professionals consider individuals with intellectual disabilities to be nutritionally vulnerable or at risk for becoming overweight or obese. Presently there is limited empirical evidence regarding the nutritional habits and education of individuals with intellectual disabilities. Currently the Special Olympics Healthy Athletes program has become the largest global public health organization dedicated to serving people with intellectual disabilities. In 2012, Special Olympics Texas provided nearly 1,600 health screenings to athletes. The screenings provide surveillance information for public health organizations in the use of health planning, prevention, and promotion. The purpose of this study was to examine the validity of a …

Isokinetic Fatigue Characteristics For The Leg Extensors Versus Flexors, Elias M. Carrillo, Matt S. Stock, Jacob Adam Mota, Kendra D. Olinghouse, Alexander S. Drusch, Brennan J. Thompson

International Journal of Exercise Science: Conference Proceedings

Maximal isokinetic muscle actions are often used in research studies to examine fatigability and even estimate muscle fiber-type. However, the majority of previous investigations have examined these topics for the leg extensors (i.e., quadriceps), and we are unaware of investigations that have specifically assessed the fatigue characteristics for the flexors (i.e., hamstrings). The purpose of this study was to compare the percent decline values for the leg extensors versus flexors for 50 and 100 repeated, maximal concentric isokinetic muscle actions. Fifteen healthy men (mean ± SD age = 23 ± 3 years; body mass = 94.1 ± 11.9 kg) with …

Inhibition Of Pim And Axl Kinases As Potential Treatments For A Variety Of Hematological Malignancies And Solid Tumors, Kent James Carpenter

Theses and Dissertations

This thesis is divided into three chapters. In each case, the goal is to achieve inhibition of a growth kinase (PIM or AXL) and subsequent arrest of cell growth and induction of apoptosis (in vitro cell culture models) or decrease in tumor volume (in vivo xenograft studies). Chapter one and chapter two discuss inhibition of proviral integration site for Moloneymurine leukemia virus (PIM) kinases. The three PIM kinases, PIM-1, PIM-2, and PIM-3, are a subfamily of serine/threonine kinases that are known to be involved in signaling pathways as downstream effectors of signal transducer and activator of transcription-5 (STAT5) signaling and …

Changes In Strength And Power Variables From Pre- To Post-Competitive Season In Collegiate Cheerleaders, C Proctor, Sr Wilson, Aj Bruenger

International Journal of Exercise Science: Conference Proceedings

Caroline Proctor, Steven R. Wilson, & Adam J. Bruenger; University of Central Arkansas, Conway, AR

Research performed on cheerleading focuses on injury rates. There is minimal research about strength and power levels of cheerleaders (CL) and how these variables change during a season. These variables may be a factor for the high injury rates experienced by CL. PURPOSE: To measure body composition, strength, and vertical jump ability before and after a cheerleading season. METHODS: 36 collegiate CL (23 Females; age = 20 ± 1 y; height = 65 ± 3 in; weight = 124 ± 18 lb;13 Males; age = …

Effects Of Prematurity On The Presence Of Weibel-Palade Bodies In Human Umbilical Vein Endothelial Cells In Situ, Niloufar Tabatabeai, Dr. John S. Gardner

Journal of Undergraduate Research

Newbom, premature infants have greater susceptibility to infection compared to older newborn infants. Although the reason for greater susceptibility to bacterial infection in premature infants is unknown, there are many reports that focus on neutrophils as the defective cell type in the immature neonatal system. However, it was recently reported by Lorant et al. that in a rat model of inflammation, neutrophils from adult rats failed to migrate efficiently in neonatal rats.’ Furthermore, we found that this defect was associated with decreased expression of Pselectin on the surface of neonatal endothelial cells in situ.

Regulation Of The Transcription Factor Creb In Skeletal Muscle After Exercise, David M. Thomson

Journal of Undergraduate Research

My laboratory is running quite smoothly now. The students in the laboratory are proficient in performing experiments, obtaining data and interpreting it. My first undergraduate students have recently graduated, and I now have a nice array of experienced and newer inexperienced students, so the work is moving forward steadily, both in terms of productivity and of student training. I enjoy seeing students come into the lab with essentially no knowledge of laboratory techniques and the particular physiological topics that we study, and within a couple of months gaining enough knowledge to contribute to an intellectual discussion of the principles we …
