Predictive Value Of The Functional Movement Screen As It Relates To Anterior Cruciate Ligament Injury, 2016 Cedarville University
Predictive Value Of The Functional Movement Screen As It Relates To Anterior Cruciate Ligament Injury, Daniel A. Herring, Kyle D. Cherry, Hannah L. Stedge
The Research and Scholarship Symposium
Introduction: Anterior cruciate ligament injuries occur over 200,000 times annually in the United States alone (Brophy, et al. 2009). This injury strains the healthcare system and affects the players, teams, parents, and the organization they are a part of. There have been, however, clinically researched risk factors that predispose athletes to ACL injury (Gignac, et al. 2015; Laible, et al. 2014). As a result, there is a clinical need for an effective screening tool to identify those athletes at risk for ACL injury. The Functional Movement Screen has been shown to be an effective screening tool for detecting athletes ...

Caffeine Enhances Non-Exercise Activity Thermogenesis In Rats, 2016 Kent State University - Kent Campus
Caffeine Enhances Non-Exercise Activity Thermogenesis In Rats, Claire Coleman, Rhiannon Shelton, Kathryn Clark, Colleen M. Novak, Lydia A. Heemstra
Undergraduate Research Symposium
Caffeine and its derivatives have been used, alone and in combination with other phytochemicals, as weight-loss supplements. Caffeine impacts several physiological and behavioral aspects of energy balance. Here, we investigate the potential for caffeine to enhance non-exercise activity thermogenesis (NEAT) even when activity level is held constant. To do this, muscle thermogenesis and energy expenditure (EE) were measured in rats during treadmill walking regimens, with and without caffeine (25 mg/kg, i.p.). Muscle heat dissipation was significantly increased by caffeine only at the end of the 25-min treadmill test. Activity-related EE, on the other hand, was significantly increased throughout ...

Robert J. Shprintzen
Velocardiofacial syndrome (VCFS), also known as 22q11.2 deletion syndrome, is a neurogenetic disorder that is associated with both learning disabilities and a consistent neuropsychological phenotype, including deficits in executive function, visuospatial perception, and working memory. Anatomic imaging studies have identified significant volumetric reductions in the parietal lobe of individuals with VCFS, but several studies have reported that the frontal lobe is relatively preserved. We used functional magnetic resonance imaging to investigate the neural correlates of non-spatial working memory in 17 youths with VCFS, 10 of their unaffected siblings, and 10 community controls (with the same proportion of learning disabilities ...

Characterizing The Performance And Behaviors Of Runners Using Twitter, Qian He, Emmanuel Agu, Diane Strong, Bengisu Tulu, Peder Pedersen
Emmanuel O. Agu
Running is a popular physical activity that improves physical and mental wellbeing. Unfortunately, up-to- date information about runners’ performance and psychological wellbeing is limited. Many questions remain unanswered, such as how far and how fast runners typically run, their preferred running times and frequencies, how long new runners persist before dropping out, and what factors cause runners to quit. Without hard data, establishing patterns of runner behavior and mitigating the challenges they face are difficult. Collecting data manually from large numbers of runners for research studies is costly and time consuming. Emerging Social Networking Services (SNS) and fitness tracking devices ...
A Context-Aware Activity Recommendation Smartphone Application To Mitigate Sedentary Lifestyles, 2015 Worcester Polytechnic Institute
A Context-Aware Activity Recommendation Smartphone Application To Mitigate Sedentary Lifestyles, Qian He, Emmanuel Agu
Emmanuel O. Agu
A sedentary lifestyle involves irregular or no physical activity. In this kind of lifestyle, people’s activities do not increase their energy expenditure substantially above resting levels. Long periods of sitting, lying, watching television, playing video games, and using the computer are typical examples. Energy expenditures at 1.0-1.5 Metabolic Equivalent Units (METs) are considered sedentary behaviors. A recent study of sedentary lifestyles found that the length of sedentary times is associated with an increased risk of diabetes, cardiovascular disease, and cardiovascular and all-cause mortality. In this study, we developed a smartphone application called “On11”, which continuously tracks and ...

Effects Of Varus Knee Alignment And Using Toe-Cages On Frontal Plane Knee Biomechanics In Stationary Cycling, Guangping Shen
Effects of varus knee alignment on the internal knee abduction moment (KAM) in walking has been widely studied. KAM has been shown to be closely associated with the development of medial knee osteoarthritis (OA). Despite the importance of the knee alignment, no studies have explored its effects on knee frontal plane biomechanics during stationary cycling. The purpose of this study was to examine the effects of varus knee alignment and using a toe-cage on the knee frontal plane biomechanics during stationary cycling. Eleven participants in each of the varus and neutral groups participated in the study. The participants performed in ...

Antibiotic-Like Actions Of Vitamin D, 2015 Marshall University
Antibiotic-Like Actions Of Vitamin D, Franklin Shuler, Josh Hendrix, Adam Short, Sammy Hodroge
Franklin D. Shuler
Vitamin D is a secosteroid hormone that has expanding importance for a healthy lifestyle and disease prevention. A multitude of studies have highlighted that vitamin D acts not only in bone and calcium homeostasis but is critically important for human immunity. The discovery that the storage form of vitamin D (25-hydroxyvitamin D3) can be locally converted to the active form (1,25-hydroxyvitamin D3) in immune cells, epithelial cells and numerous other non-renal tissues highlights the importance of maintaining sufficient stores. When responding to a specific external stimulus, like bacterial invasion, intracrine synthesis of active vitamin D has the ability to ...
An Overview Of Leber’S Hereditary Optic Neuropathy, 2015 Liberty University
An Overview Of Leber’S Hereditary Optic Neuropathy, Matthew R. Dalton
Typically affecting males ranging from 20 to 24 years of age, Leber’s Hereditary Optic Neuropathy (LHON) is a disorder that is characterized by an acute loss of central vision. Although a heritable disease, LHON does not follow the patterns of classical Mendelian genetics. In fact, one of the most striking characteristics of LHON is that the disease is virtually always inherited maternally. Unlike most genetic disorders that result from a mutation in genomic DNA, LHON is caused by a mutation in the genetic information of mitochondria (mtDNA). Currently there is no treatment for LHON. Despite this, pharmaceutical interventions and ...
A Clinically Relevant Relevant Post-Traumatic Osteoarthritis Mouse Model, 2015 The University of Western Ontario
A Clinically Relevant Relevant Post-Traumatic Osteoarthritis Mouse Model, Chantel P. Arce
Electronic Thesis and Dissertation Repository
Osteoarthritis affects 13-20% of Canadians with the majority being under 65years of age. Post-traumatic osteoarthritis (PTOA) is of great concern in young athletes following knee injury. Current research attempts at modeling the disease fall short. This study aimed to incorporate two important aspects of injury, the nature of the injury and the post-injury standard of care in humans, to a model of PTOA in mice. The study validated a non-invasive protocol to elicit an anterior cruciate ligament (ACL) injury at varying loading speeds addressing the closed capsule nature of an ACL injury that occurs in humans. Secondly, we proposed a ...
Viewing The Extracellular Matrix: An Imaging Method For Tissue Engineering, 2015 Purdue University
Viewing The Extracellular Matrix: An Imaging Method For Tissue Engineering, Michael Drakopoulos, Sarah Calve
The Summer Undergraduate Research Fellowship (SURF) Symposium
The field of regenerative medicine seeks to create replacement tissues and organs, both to repair deficiencies in biological function and to treat structural damage caused by injury. Scaffoldings mimicking extracellular matrix (ECM), the structure to which cells attach to form tissues, have been developed from synthetic polymers and also been prepared by decellularizing adult tissue. However, the structure of ECM undergoes significant remodeling during natural tissue repair, suggesting that ECM-replacement constructs that mirror developing tissues may promote better regeneration than those modeled on adult tissues. This work investigated the effectiveness of a method of viewing the extracellular matrix of developing ...
Effects Of Pelvis Impact Angle And Hip Muscle Forces On Hip Fracture Risk During A Fall Using An Advanced Hip Impact Simulator, Woochol J. Choi, Stephen N. Robinovitch
Physical Therapy Faculty Articles and Research
"Over 90% of hip fractures in older adults are caused by falls . Whether a given fall will cause hip fracture depends on bone strength, and on the impact force and stress applied to the bone during impact . Improved understanding is required on how peak bone stresses during a fall depend on the mechanics of a fall, and on the state of contraction at the moment of impact of the muscles spanning the hip. Recently, Choi et al showed that, for lateral impact to the hip, peak stresses decrease with increases in hip abductor muscle force . In the ...
Influence Of Pelvis Impact Angle During A Fall: On The Protective Benefit Of Hip Protectors, 2015 Chapman University
Influence Of Pelvis Impact Angle During A Fall: On The Protective Benefit Of Hip Protectors, Woochol J. Choi, Stephen N. Robinovitch
Physical Therapy Faculty Articles and Research
"Over 90% of hip fractures are due to falls . Laboratory measures have shown that wearable hip protectors reduce impact forces to the proximal femur during a simulated sideways fall on the hip [2, 3]. However, clinical evidence suggests that hip fractures still occur when hip protectors are worn . Furthermore, while falls in real life result in a variety of impact configurations, biomechanical tests to date have focused only on lateral impact to the pelvis. In the current study, we examined how the force reduction provided by wearable hip protectors is affected by pelvis impact configuration during simulated sideways ...
The Role Of Bone Sialoprotein In The Tendon-Bone Insertion, 2015 The University of Western Ontario
The Role Of Bone Sialoprotein In The Tendon-Bone Insertion, Ryan M. Marinovich
Electronic Thesis and Dissertation Repository
Tendons and ligaments insert into bone through a transitional tissue termed the enthesis which is susceptible to injury and difficult to repair. Entheses contain a region of calcified fibrocartilage (CFC), however mineral-associated proteins in this tissue remain poorly characterized. Bone sialoprotein (BSP) is a phosphoprotein associated with mineralizing tissues. In these studies BSP was identified in the CFC of entheses by immunohistochemistry. Analysis of the entheses of Bsp-/- mice indicate abnormalities in the CFC. Compared to controls, the CFC of the quadriceps tendon enthesis is 28% and 41 % longer in 15 week and 14 month old Bsp-/- mice, respectively. MicroCT ...
Possible Molecular Mechanisms Underlying Age-Related Cardiomyocyte Apoptosis In The F344xbn Rat Heart, 2015 Marshall University
Possible Molecular Mechanisms Underlying Age-Related Cardiomyocyte Apoptosis In The F344xbn Rat Heart, Sunil Kakarla, Kevin Rice, Anjaiah Katta, Satyanarayana Paturi, Miaozong Wu, Madhukar Kolli, Saba Keshavarzian, Kamran Manzoor, Paulette Wehner, Eric Blough
Despite advances in treatment, age-related cardiac dysfunction still remains a leading cause of cardiovascular death. Recent data have suggested that increases in cardiomyocyte apoptosis may be involved in the pathological remodeling of heart. Here, we examine the effects of aging on cardiomyocyte apoptosis in 6-, 30-, and 36-month-old Fischer344xBrown Norway F1 hybrid rats (F344XBN). Compared with 6-month hearts, aged hearts exhibited increased TdT-mediated dUTP nick end labeling–positive nuclei, caspase-3 activation, caspase-dependent cleavage of α-fodrin and diminished phosphorylation of protein kinase B/Akt (Thr 308). These age-dependent increases in cardiomyocyte apoptosis were associated with alterations in the composition of the ...
