Fractal Time Series Analysis Of Human Heartbeat Intervals In A Change Blindness Task, Sheldon M. Russell, Gregory J. Funke, Camilla C. Knott, Benjamin A. Knott

International Symposium on Aviation Psychology - 2009

Fractal analysis is a set of techniques used in the study of complex systems to understand patterns of variability that are often observed in non-linear and natural systems. These techniques have been successfully applied to the study of human physiology, such as gait, heart rate variability, and respiration (West, 2004). Understanding variability in physiological measures may provide insight into human performance, individual workload, and stress. As an exploration of the possible contributions of fractal analysis to human performance, heart rate data from an existing research study was re-analyzed using methods common in fractal analysis of time series data. Results indicate …

F2-Isoprostanes As Novel Biomarkers For Type 2 Diabetes: A Review, Subramanian Kaviarasan, Sekaran Muniandy, Rajes Qvist, Ikram Shah Ismail

Research Publications (2006 to 2010)

Oxidative stress (OS) has been implicated as one of the major underlying mechanisms behind many acute and chronic diseases. However, the measurement of free radicals or their end products is complicated. Isoprostanes, derived from the non-enzymatic peroxidation of arachidonic acid are now considered to be reliable biomarkers of oxidant stress in the human body. Isoprostanes are involved in many of the human diseases such as type 2 diabetes. In type 2 diabetes elevated levels of F-2-Isoprostanes (F-2-IsoPs) have been observed. The measurement of bioactive F-2-IsoPs levels offers a unique noninvasive analytical tool to study the role of free radicals in …

Glossolalia Influences On Stress Response Among Apostolic Pentecostals, Christopher Dana Lynn

Legacy Theses & Dissertations (2009 - 2024)

This study tests the hypothesis that long–term experience of Apostolic Pentecostal glossolalia or “speaking in tongues” reduces the reactivity of biological stress response to normal or "daily" stressors. Glossolalia is a form of religious dissociation. Dissociation is a universal capacity often conflated with “trance.” It refers to the partitioning of awareness associated with a variety of cross–cultural forms, from daydreaming and denial to possession trance, shamanic spirit journeys, and dissociative identity disorder. Dissociation is believed to reduce or filter stress by mediating evaluation of potential stressors and reactivity of the mechanisms of biological stress response. Previous studies have examined these …

The Identification And Characterization Of Estrogen Receptors In The Mouse And Human Lens And Their Role In Cataract Development, Mary Rachel Kirker

Electronic Theses and Dissertations

The increased risk of age-related cataracts in postmenopausal women and studies in animal models suggest that estrogen may have a protective role in the lens. However, very little is known regarding the role of estrogen and its receptors in the lens. To begin unraveling the estrogen signaling mechanism in the lens, the following aims were investigated: 1) to determine if estrogen receptors are expressed in the lens, [125I]-17beta-estradiol binding and mRNA expression of ERalpha, ERbeta, and GPR30 were examined in the mouse and human lens; 2) to determine if the loss of ERalpha and/or ERbeta receptors will induce spontaneous development …

Gender-Benders': Sex And Law In The Constitution Of Polluted Bodies, Dayna Nadine Scott

Articles & Book Chapters

This paper explores how law might conceive of the injury or harm of endocrine disruption as it applies to an aboriginal community experiencing chronic chemical pollution. The effect of the pollution in this case is not only gendered, but gendering: it seems to be causing the ‘production’ of two girl babies for every boy born on the reserve. This presents an opening to interrogate how law is implicated in the constitution of not just gender but sex. The analysis takes an embodied turn, attempting to validate the real and material consequences of synthetic chemicals acting on bodies — but uncovers …

Effects Of A Yeast Β-Glucan Supplement On Symptoms Of Upper Respiratory Tract Infection In Free-Living College-Aged Males, Casey E. Gorham

Graduate Student Theses, Dissertations, & Professional Papers

The focus of previous research has demonstrated that both oat and yeast ß-glucan benefits immunosuppressed populations. However, previous research has not, to our knowledge, investigated the effects of a yeast ß-glucan on the ummune functioning of healthy, free-living human populations. PURPOSE: The goal of this research was to evaluate the effects of a yeast ß-glucan on symptoms of upper respiratory tract infection in healthy, free-living, college-aged males. METHODOLOGY: The WURSS-44, a reliable, validated survey used for determining symptoms of upper respiratory tract infection was filled out online daily by 79 male subjects between the ages of 18 and 40. Subjects …

Insights Into Expression, Cellular Localization, And Regulation Of Supernatant Protein Factor, A Putative Regulator Of Cholesterol Biosynthesis, Elzbieta Ilona Stolarczyk

University of Kentucky Doctoral Dissertations

SPF (Supernatant Protein Factor) is a cytosolic protein that stimulates at least two enzymes in the cholesterol biosynthetic pathway: squalene monooxygenase and HMGCoA reductase. The mechanism of action has not been established but may be related to lipid transfer between intracellular membranes.

There are three human genes for SPF: SEC14L2 (SPF1), SEC14L3 (SPF2) and SEC14L4 (SPF3). The present study differentiates these closely related genes by evaluating their tissue-specific and relative expression levels. SPF1 mRNA was found to be most abundant in liver, mammary gland and stomach. SPF2 showed negligible expression in all tissues tested; SPF3 expression pattern was similar to …

A Tiny Problem With Huge Implications - Nanotech Agents As Enablers Or Substitutes For Banned Chemical Weapons: Is A New Treaty Needed?, Evan J. Wallach

Fordham International Law Journal

The underlying thesis of this Article is that while smaller-sized particles and separate nano-sized carriers of known agents are clearly covered by the CWC, nanomimics are not as squarely within the relevant provisions. The bulk of this Article deals with that question. Despite the invitation to woolgather, this Article is limited to the tightest possible analytical approach. Part I begins with definitions of chemical and biological agents within existing treaties, and of nanoproducts, including those existing beyond presently-known technical capabilities, but which are at least reasonably conceivable (“nanobots”). Part II provides an overview of treaty law that is potentially applicable …

Factors In Bmi Increase Among Multicultural Freshmen., Leah Haritan

Master's Theses

This observational research examines body mass index (BMI) changes in multicultural freshmen attending a large public urban university. It explores factors associated with BMI increase and investigates behavior changes and perceptions related to diet and body weight. The study utilizes an online survey distributed in November 2007 and again in April 2008. All 3,260 freshmen were eligible to participate. Initial response rate was 23%; 44% of initial respondents completed both surveys (N = 337). Results revealed a significant increase in BMI for on-campus residents, Caucasians, and males (P < 0.05). Decreased vegetable intake was associated with a BMI increase of less than one (P < 0.05). Fruits and vegetables were perceived by most as healthful; their high cost, and limited variety and availability on campus were deemed potential barriers to intake. Freshman weight gain may be a function of gender, residence, and ethnicity, and deserves further examination.

A Predictive Model Of Cognitive Performance Under Acceleration Stress, Richard Andrew Mckinley

Browse all Theses and Dissertations

Extreme acceleration maneuvers encountered in modern agile fighter aircraft can wreak havoc on human physiology thereby significantly influencing cognitive task performance. Increased acceleration causes a shift in local arterial blood pressure and profusion causing declines in regional cerebral oxygen saturation. As oxygen content continues to decline, activity of high order cortical tissue reduces to ensure sufficient metabolic resources are available for critical life-sustaining autonomic functions. Consequently, cognitive abilities reliant on these affected areas suffer significant performance degradations. This goal of this effort was to develop and validate a model capable of predicting human cognitive performance under acceleration stress. An Air …

Acetylcholine Muscarinic Receptor-Mediated Contractility Of Ovine Pulmonary Arteries: Changes With Maturation And Chronic Hypoxia, Dangtue Hu Nguyen

Honors Theses

Pulmonary vasculature tone is mediated by Acetylcholine Muscarinic Receptors (mAChR) located on the vascular smooth muscle wall which are responsible for vasoconstriction through the activation of Ca^'*’ dependant intracellular signaling pathways and by the endothelium which is responsible for vasodilation through the generation of Nitric Oxide (NO). The dismption and subsequent loss of the endothelium results in vasoconstriction of pulmonary arteries (PA). This effect is observed in several studies utilizing different animal models. Chronic Hypoxia (CH) has been shown to dismpt the endothelium which in turn alleviates the vasodilatory response associated with acetylcholine (ACh) stimulation. The interplay between smooth muscle …
