Individual Eeg Asymmetry As A Predictor Of Hydration Status During Exercise In The Heat, Ayano Katayama

Electronic Theses and Dissertations

Hydration behavior varies among individuals; continuous and correct fluid consumption behavior prevents decreased physical performance and severe dehydration, especially during extended exercise and hot environments. Therefore, the purpose of the present study was to examine individual frontal alpha electroencephalographic asymmetry index (FAI) score in eu-hydrated, hypo-hydrated, and exercise in well-trained men and assess if there is a correlation between FAI score and individual ad libitum fluid consumption behavior. Subjects were kinesiology major college students ranging from 21 to 29 years of age. Subjects were categorized either approach group (n = 8) with resting FAI score more than 0 or avoidance …

Artemisinin: From Chinese Herbal Medicine To Modern Chemotherapy, Anthony Butler

HIMALAYA, the Journal of the Association for Nepal and Himalayan Studies

Malaria is a disease that has blighted humankind since early times. The first antimalarial treatment available to Europeans was the dried bark of the cinchona tree from Peru. The main problem in its use was adulteration by other material. The ‘active principle’ was first extracted in 1820 and named quinine. It was found to be a more powerful and reliable drug than cinchona bark. Once its chemical structure had been determined, it was possible to synthesize substances chemically related to quinine that were equally powerful but could be manufactured industrially. Mepacrine (atabrine) was amongst the most successful, but had adverse …

Finalists were assigned to one of two groups, Top 3 (n=6) and Rest-of-Field (n=10) based on their placement at these championships. Highlighted was the mean velocity difference (0.30 m/s) and large effect size (0.88) between …

Taxonomic Features And Comparison Of The Gut Microbiome From Two Edible Fungus-Farming Termites (Macrotermes Falciger, M. Natalensis) Harvested In The Vhembe District Of Limpopo, South Africa, Stephanie L. Schnorr, Courney A. Hofman, Shandukani R. Netschifhefhe, Frances D. Duncan, Tanvi P. Honap, Julie Lesnik, Cecil M. Lewis

Anthropology Faculty Research

Background Termites are an important food resource for many human populations around the world, and are a good supply of nutrients. The fungus-farming ‘higher’ termite members of Macrotermitinae are also consumed by modern great apes and are implicated as critical dietary resources for early hominins. While the chemical nutritional composition of edible termites is well known, their microbiomes are unexplored in the context of human health. Here we sequenced the V4 region of the 16S rRNA gene of gut microbiota extracted from the whole intestinal tract of two Macrotermes sp. soldiers collected from the Limpopo region of South Africa. Results …

Genome-Scale Metabolic Model Of The Rat Liver Predicts Effects Of Diet Restriction., Priyanka Baloni, Vineet Sangar, James T Yurkovich, Max Robinson, Scott Taylor, Christine M Karbowski, Hisham K Hamadeh, Yudong D He, Nathan D Price

Articles, Abstracts, and Reports

Mapping network analysis in cells and tissues can provide insights into metabolic adaptations to changes in external environment, pathological conditions, and nutrient deprivation. Here, we reconstructed a genome-scale metabolic network of the rat liver that will allow for exploration of systems-level physiology. The resulting in silico model (iRatLiver) contains 1,882 reactions, 1,448 metabolites, and 994 metabolic genes. We then used this model to characterize the response of the liver's energy metabolism to a controlled perturbation in diet. Transcriptomics data were collected from the livers of Sprague Dawley rats at 4 or 14 days of being subjected to 15%, 30%, or …

West Virginia’S Sugary Drink Tax: Examining Print Media Frames In Local News Sources, Lauri Andress, Ogaga Urhie, Christine Compton

Journal of Appalachian Health

Introduction: Framing is an important aspect of the policy process that helps the public and decision makers sort through and resolve highly charged claims about an issue. Through slight changes in the presentation of issues, a framing effect may alter public support. The way a proposed sugary drink tax is discussed in public discourse and by the media significantly influences policy acceptance. Given the public health significance of obesity and diabetes in West Virginia (WV) the study of media frames employed to represent a sugary drink tax policy is useful.

Methods: Using quantitative content analysis, this study assessed news articles—published …

Tools To Improve Interruption Management, Matthew R. Munns

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

Interruptions carry a high cost, especially to software developers. To prevent unnecessary interruptions, several technologies are being explored that can help manage the timing of interruptions, such as displaying the interruptibility of a worker to their peers. Relatively simple algorithms utilizing computer interaction data have been created and used successfully in the workplace, while technology using bio-metric emotion recognition to detect the interruptibility of a user is also being developed.

Effect Of Heart Rate Variability Biofeedback On Sleep, Joshua Mercadel

Theses and Dissertations

Healthy amounts of sleep is vital for normal human functions such as daily learning, memory, emotional state and cardiovascular function. Studies conducted previously have shown sleep deprivation to be associated with increases in sympathetic activity contributing to autonomic nervous system (ANS) dysregulation. HRV biofeedback (HRVB) training induces HRV coherence, a condition that maximizes HRV and facilitates autonomic and cardiorespiratory homeostasis. This randomized, controlled, intervention trial will test the hypothesis that HRVB can improve HRV coherence and increase overall sleep quality. Patients are randomized to previously established HRVB or sham protocols (n=40 each, total planned enrollment N=80). Each participant completes a …

Nonlinear Direct Torque Control Of Interior Permanent Magnet Synchronous Motor Drive, Jackson Justo

Tanzania Journal of Engineering and Technology (TJET)

This paper presents a nonlinear direct torque control (NDTC) strategy of interior permanent magnet synchronous motors (IPMSMs) for electric vehicle (EV) propulsion. The proposed NDTC scheme applies a nonlinear model of IPMSM to dynamically determine the optimal switching states that optimize the EV drivers’ decision to reduce the workload. Moreover, the proposed NDTC method has a simple control structure and can explicitly handle system constraints and nonlinearities. The performance evaluation is conducted via a prototype IPMSM test-bed with a TMS320F28335 DSP. Comparative experimental results provide the evidence of improvements of the proposed NDTC strategy over the conventional DTC strategy by …

A Tale Of Two Books: The Relationship Between John Harvey Kellogg’S Living Temple And Ellen G. White’S Ministry Of Healing, Thomas Rasmussen

Andrews University Seminary Student Journal

In contemporary society John H. Kellogg is more known for his medical inventions, than he is for the book The Living Temple, which was published in 1903. However, within Adventism the name Kellogg denotes crisis and controversy. The thesis of this paper is that Ellen White responded to the Kellogg’s publication in three ways: personally—to John Kellogg; prophetically—to the Seventh-day Adventist Church; and publicly—with the book The Ministry of Healing, which was published two years later in 1905. It is the public response that is of primary interest to this paper. Ellen White wrote many personal letters to Kellogg leading …

Computer Vision Machine Learning And Future-Oriented Ethics, Abagayle Lee Blank

Honors Projects

Computer Vision Machine Learning (CVML) in the application of facial recognition is currently being researched, developed, and deployed across the world. It is of interest to governments, technology companies, and consumers. However, fundamental issues remain related to human rights, error rates, and bias. These issues have the potential to create societal backlash towards the technology which could limit its benefits as well as harm people in the process. To develop facial recognition technology that will be beneficial to society in and beyond the next decade, society must put ethics at the forefront. Drawing on AI4People’s adaption of bioethics for AI, …

Cardiovascular Changes During Dialogue, Patricia Liehr

Dissertations

This study was designed to explore the experience of listening, noting how listening was distinct from talking and from silence. There was interest in the potential for listening to engender lowered physiological arousal. Listening was defined within an interpersonal context, as one person listened to another tell a story. Clinical experience has demonstrated that persons who are listening to a clinician share a story often relax. Psychophysiological measures were used to assess the experience of listening. Cardiovascular parameters (mean arterial pressure, systolic blood pressure, diastolic blood pressure, heart rate, skin temperature) and eye contact (videotaped data) were measured during listening. …

Mitochondrial Activity And Skeletal Muscle Insulin Resistance In Kidney Disease, Jane E. Carré, C Affourtit

School of Biomedical Sciences

Insulin resistance is a key feature of the metabolic syndrome, a cluster of medical disorders that together increase the chance of developing type 2 diabetes and cardiovascular disease. In turn, type 2 diabetes may cause complications such as diabetic kidney disease (DKD). Obesity is a major risk factor for developing systemic insulin resistance, and skeletal muscle is the first tissue in susceptible individuals to lose its insulin responsiveness. Interestingly, lean individuals are not immune to insulin resistance either. Non-obese, non-diabetic subjects with chronic kidney disease (CKD), for example, exhibit insulin resistance at the very onset of CKD, even before clinical …

Influence Of Hydration Status On Running Performance And Makers Of Psychological And Physiological Stress In High School Cross Country Runners, Joshua Granger

LSU Master's Theses

Adequate hydration is an important attribute to an individual’s health and wellbeing. This is highlighted in athletic populations, who are at great risk for hypohydration, regardless of age, sex, and sport. The rampant hypohydration observed in athletes is present at all levels of competition, from professional athletes, with access to substantial monetary and nutrition support to division 3 and recreational athletes who often face monetary challenges. This trend continues to trickle down to lower levels of competition, such as high school, where athletes often practice and compete in dehydrated states. Practicing in these hypohydrated states can cause health issues such …

Design For Sustainable Entangled Human-Nature Systems, Emīlija Veselova

Nordes Conference Series

Humanity must rapidly transition towards sustainable futures. Reaching planetary sustainability requires care for nature and radical transformation of human-made systems. Human and natural systems co-exist in extensive, complex, multi-layered entanglement. Design for sustainability and, ultimately, all design, will need to be transformed towards design for sustainable entangled human-nature systems. This paper outlines six developments to support this transformation. It suggests that all design projects must (1) be viewed as interlinked to human-nature systems and their sustainability, (2) include natural systems and entities as key stakeholders, and (3) include transdisciplinary perspectives on the entangled systems and sustainability. Moreover, design could adopt …

Why Care About Virtual Landscapes? Immersive Open World Gaming Related To Positive Health, Paul Roncken

Nordes Conference Series

For some reason many people enjoy, spend long hours and pay for being out on virtual fields, playing an avatar that needs to hunt, prey, hide, survive and interact with all kinds of programmed entities and online players. Surely the designers and programmers deserve praise for their efforts and achievements in yearly progress on more detailed and increasingly immersive virtual experiences. But does that suffice to care about virtual landscapes other than classifying them as artificial places for fun and diversion? In this paper I will make a first attempt to relate virtual landscape experiences to accumulated insights in environmental …

A Paper-Based Elisa Device For The Rapid Detection Of Ischemic Stroke, Andrea Larsen

Baker/Koob Endowments Awarded Projects

Diagnosing an ischemic stroke accurately and quickly is essential for appropriate treatment and results in more effective management of the stroke, leading to better patient outcomes. Specifically, the determination of ischemic versus hemorrhagic stroke leads to critically different treatment paths, which would be potentially fatal if administered incorrectly. Currently, ischemic strokes are diagnosed through a series of tests, including a physical examination, CT scans, and a panel of blood tests to exclude hemorrhagic stroke or other similarly presenting conditions, in order to administer tPA (the main treatment) within the three hour window. The discovery of biomarkers, molecules which are upregulated …

Agency And Creativity: An Eye On Gender Identity In Four Egyptian Novels, Maha Mosalem

Theses and Dissertations

For most scholars, agency is a term that has most traditionally been coined with free will, resistance, and intentionality (Giddens, 1979; Ahearn, 2001). In this study, however, the construct is examined from a linguistic perspective aiming at exploring its creative dimensions in relation to gender identity in four Egyptian novels; Bayna ʔal-qaṣrayn (Palace Walk), ʔal-Bāb ʔal-maftūḥ (The Open Door), ʔu:ri:du rajulan (I Need a Man), and ʃaġaf (Passion). By adopting a mediated discourse analysis approach (MDA) (Scollon, 2002), this study examined the connections between discourse and action in social interactions. Using the grammatical, semantic, and discursive analysis, the examination focused …

Effects Of Life-Long Wheel Running Behavior On Plantar Flexor Contractile Properties, Alexander Nicholas Beechko

Electronic Theses, Projects, and Dissertations

Aging in skeletal muscle is characterized by a loss in muscular performance. This is in part related to the direct loss of muscle mass due to senescence, known as sarcopenia. With age, skeletal muscles lose force production, contractile speed, and power production. The force velocity relationship of muscle is a product of force production and contraction speed, both of which decline with age; however, the mechanisms and trajectory of this decline are not well understood. Exercise has positive effects on muscle, and thus may assist in maintaining performance in old age. However, few long-term studies have been performed to examine …

International Comparison Of The Levels And Potential Correlates Of Objectively Measured Sedentary Time And Physical Activity Among Three-To-Four-Year-Old Children, Kaiseree I. Dias, James White, Russell Jago, Greet Cardon, Rachel Davey, Kathleen F. Janz, Russell R. Pate, Jardena J. Puder, John J. Reilly, Ruth Kipping

Faculty Publications

Physical activity (PA) patterns track from childhood through to adulthood. The study aimed to determine the levels and correlates of sedentary time (ST), total PA (TPA), and moderate-to-vigorous PA (MVPA) in preschool-aged children. We conducted cross-sectional analyses of 1052 children aged three-to-four-years-old from six studies included in the International Children’s Accelerometry Database. Multilevel linear regression models adjusting for age, gender, season, minutes of wear time, and study clustering effects were used to estimate associations between age, gender, country, season, ethnicity, parental education, day of the week, time of sunrise, time of sunset, and hours of daylight and the daily minutes …

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano

Journal of Human Performance in Extreme Environments

Technical freediving can be defined as freediving augmented by the use of oxygen-enriched gases or oxygen before, during, or after a freedive. As a result of these techniques, breath-hold divers can visit and enjoy underwater wrecks, reefs, and other diving locations previously located at depths unreachable to apnea divers. By pre-breathing oxygen-enriched gases in conjunction with hyperventilation—which decreases the partial pressure of carbon dioxide (PCO2)—the technical freediver now has additional oxygen to facilitate aerobic respiration during the dive. In addition, pre-breathing oxygen decreases tissue nitrogen tensions, which limits inert gas loading and decreases the risk of decompression sickness (DCS). Finally, …

Semi-Automatic Spatio-Temporal Reconstruction Of The Left Ventricle From Cmr, Mohamed Abdelkhalek

Theses and Dissertations

Cardiovascular simulation and modelling have recently grown into a promising area of research, with a major interest in simulating biophysical phenomena within patient specific environments [1, 2, 3, 4]. With a major focus being faster, less computationally expensive (approaching real time) methods along with reasonable accuracy to actually translate research to application in clinical decision making. This work presents a quick computational framework for building a semi-automatic platform building patient specific spatio-temporal kinematic models of the left ventricle, allowing interactive visualization and detailed quantification of structural e.g. (volume, wall thickness) and functional parameters e.g. (radial Strain, circumferential Strain) of the …

Composite Biomaterial Repair Strategy To Restore Biomechanical Function And Reduce Herniation Risk In An Ex Vivo Large Animal Model Of Intervertebral Disc Herniation With Varying Injury Severity, Warren W. Hom, Melanie Tschopp, Huizi A. Lin, Philip Nasser, Damien M. Laudier, Andrew C. Hecht, Steven B. Nicoll, James C. Iatridis

Publications and Research

Back pain commonly arises from intervertebral disc (IVD) damage including annulus fibrosus (AF) defects and nucleus pulposus (NP) loss. Poor IVD healing motivates developing tissue engineering repair strategies. This study evaluated a composite injectable IVD biomaterial repair strategy using carboxymethylcellulose-methylcellulose (CMC-MC) and genipincrosslinked fibrin (FibGen) that mimic NP and AF properties, respectively. Bovine ex vivo caudal IVDs were evaluated in cyclic compression-tension, torsion, and compression-to-failure tests to determine IVD biomechanical properties, height loss, and herniation risk following experimentally-induced severe herniation injury and discectomy (4 mm biopsy defect with 20% NP removed). FibGen with and without CMC-MC had failure strength similar …
