The Phytotronist And The Phenotype: Plant Physiology, Big Science, And A Cold War Biology Of The Whole Plant., David Munns
The Phytotronist And The Phenotype: Plant Physiology, Big Science, And A Cold War Biology Of The Whole Plant., David Munns
Publications and Research
This paper describes how, from the early twentieth century, and especially in the early Cold War era, the plant physiologists considered their discipline ideally suited among all the plant sciences to study and explain biological functions and processes, and ranked their discipline among the dominant forms of the biological sciences. At their apex in the late-1960s, the plant physiologists laid claim to having discovered nothing less than the “basic laws of physiology.” This paper unwraps that claim, showing that it emerged from the construction of monumental big science laboratories known as phytotrons that gave control over the growing environment. Control …

The Effect Of Β-Hydroxy-Β-Methylbutyrate (Hmb) Supplementation On Neuromuscular Performance Following Fatiguing Exercise In Healthy Subjects, Jordon W. Macht
The Effect Of Β-Hydroxy-Β-Methylbutyrate (Hmb) Supplementation On Neuromuscular Performance Following Fatiguing Exercise In Healthy Subjects, Jordon W. Macht
Theses and Dissertations--Kinesiology and Health Promotion
Supporters of a nutritional supplement, β-Hydroxy-β-Methylbutyrate (HMB) supplementation, claim that it will increase the muscular strength gains and lean muscle mass gains seen during a resistance training program. It has been suggested that HMB supplementation does this by preventing muscle damage or by regenerating damaged muscle cell membranes. However, no research has evaluated the effect of HMB supplementation on low frequency fatigue. Therefore, the purpose of this study was to determine if three weeks of HMB supplementation could attenuate the effects of low frequency fatigue caused by eccentric muscle contractions of the tibialis anterior muscle. A total of 33 healthy …
The Effects Of Spinal Manipulative Therapy On Isokinetic Strength And Postactivation Potentiation, Grant D. Sanders
The Effects Of Spinal Manipulative Therapy On Isokinetic Strength And Postactivation Potentiation, Grant D. Sanders
Theses and Dissertations--Kinesiology and Health Promotion
Spinal manipulative therapy (SMT) is a therapeutic procedure employed by various healthcare practitioners for alleviating acute and chronic musculoskeletal complaints. This form of treatment is also delivered to enhance the performance and augment the rehabilitation of athletes. However, despite research findings alleging the strength-modulating effects of SMT alongside numerous professional athletes’ positive anecdotal claims concerning its results, the physiological processes to explain its effects remain largely unexplained. Therefore, the purpose of this work was to investigate the effects of SMT in a college-aged sample population with two experiments.
The first study examined the effect of SMT targeting the lumbosacral region …
Parent Involvement And Science Achievement During Students’ Transition Years From Elementary School To Middle School: A Cross-Lagged Panel Analysis Using Ecls-K, Letao Sun
Theses and Dissertations--Educational Policy Studies and Evaluation
Transitioning from elementary school to middle school can be a difficult time for many adolescents. It is a period often correlated with a decline in students’ academic achievement, perceptions of performance, potential, and value in schooling. Research has shown evidence that parents’ involvement in their children’s education significantly influences children’s academic achievement. However, there are many conflicting findings regarding this relationship.
The primary purpose of this study is to extend existing research on academic achievement by examining the causal relationship between parent involvement and science achievement during the transition years, using data from the Early Childhood Longitudinal Study, Kindergarten Class …
The Effect Of Cholesterol On The Osteoblast Responsiveness To Hydrodynamic Pressure Stimulation, Kristen Lough
The Effect Of Cholesterol On The Osteoblast Responsiveness To Hydrodynamic Pressure Stimulation, Kristen Lough
Theses and Dissertations--Biomedical Engineering
Hypercholesterolemia is a risk factor for osteoporosis but the underlying mechanism is unknown. Previous evidence suggests that osteoporosis results from an impaired regulation of osteoblasts by fluid pressure fluctuations in the bone matrix. Recently, our laboratory showed that enhanced cholesterol in the cell membrane, due to hypercholesterolemia, alters leukocyte mechanosensitivity. We predict a similar link between osteoblasts and hypercholesterolemia leading to osteoporosis. Specifically, we hypothesize that extracellular cholesterol modifies the osteoblast sensitivity to pressure. MC3T3-E1 cells were exposed to hydrodynamic pressures regimes (mean=40mmHg, amplitude=0-20mmHg, frequency=1Hz) for 1-12 hours. To assess the impact of membrane cholesterol enrichment, cells were pre-treated with …
Critical-Reflective Thinking: A Phenomenology, Margot D. Wielgus
Critical-Reflective Thinking: A Phenomenology, Margot D. Wielgus
Theses and Dissertations--Philosophy
This dissertation formulates and describes a type of thinking called critical-reflective thinking. Examples of critical-reflective thinking appear in the works of many major Western philosophical figures, including the main thinkers considered here, Plato, Martin Heidegger, Hannah Arendt, and Henry David Thoreau. Although this list of thinkers is eclectic, these philosophers come together in describing a common phenomenon, although they do not thematically designate or explain it. Their works illustrate a type of thinking in which people are invited by prompting events to consider their presuppositions—notions they have taken as true without prior consideration. I have deemed this phenomenon “critical-reflective thinking” …
Insights Into Perspectives On Environmental Sustainability, Amber R. Shobe
Insights Into Perspectives On Environmental Sustainability, Amber R. Shobe
Theses and Dissertations--Community & Leadership Development
As scientists become more aware of the imposing threats associated with climate change, university leaders are encouraged to become familiar with the principles of sustainability. Abundant research already supports the relevance of environmental sustainability in higher education; however, there exists a gap in the literature which investigates an understanding of environmental sustainability and the implementation of its practices. By examining colleges at the University of Kentucky, this study identifies organizational barriers to recognizing a thorough understanding of environmental sustainability at the departmental level. The results indicate that out of the eight colleges selected, two have no existing environmental sustainability programs …
The Influence Of Media Ingredients And Ph On The Growth Of Chloromonas Rosae Var. Psychrophila, Caoli Zheng
The Influence Of Media Ingredients And Ph On The Growth Of Chloromonas Rosae Var. Psychrophila, Caoli Zheng
Theses and Dissertations--Biosystems and Agricultural Engineering
In order to utilize algae to fix CO2 and reduce Greenhouse gas emissions, large-scale, year-round algae cultivation will be required. This will require alga species that thrive in colder weather with media recipes based on commercially available fertilizers. The objectives of this study were to evaluate the effect of using commercial based media and the effect of pH when growing the cold-temperature algae Chloromonas rosae var. psychrophila. Commercial grade media ingredients urea, potash, triple superphosphate, and Sprint 330® were used to provide nitrogen, potassium, phosphorus, and EDTA with iron, respectively. The commercial grade media supported growth similar to the growth …
Up Regulation Of Heat Shock Protein 70b (Hsp70b) And Ssa1 In Chlamydomonas Reinhardtii Via Hsp70a-Rbcs2 And Psad Promoter, B. Kirtley Amos
Up Regulation Of Heat Shock Protein 70b (Hsp70b) And Ssa1 In Chlamydomonas Reinhardtii Via Hsp70a-Rbcs2 And Psad Promoter, B. Kirtley Amos
Theses and Dissertations--Biosystems and Agricultural Engineering
Fabrication of effective algae cultivation systems adjacent to coal-fired power plants to fixate waste CO2 would represent a sizable step towards achieving a carbon neutral energy cycle. However, emission gas would elevate the algal cultivation system temperature and decreases its pH without expensive preprocessing. Increased temperature and acidity constitutes a profound stress on the algae. Although stressed algae produce heat shock proteins (HSPs) that promote protein folding and protect against stress, the ordinary biological response is insufficient to protect against coal flue gas. Experimental upregulation of HSPs could make algae respond to the stress caused by high temperatures and …
Dietary Selenium Supplementation: Effects On Neurodegeneration Following Traumatic Brain And Spinal Cord Injury, Carolyn A. Crowdus Meyer
Dietary Selenium Supplementation: Effects On Neurodegeneration Following Traumatic Brain And Spinal Cord Injury, Carolyn A. Crowdus Meyer
Theses and Dissertations--Neuroscience
Traumatic brain and spinal cord injury continue to be substantial clinical problems with few available treatment strategies. Individuals who are at a greater risk for sustaining a central nervous system (CNS) injury, such as professional athletes and military personnel, may benefit from a prophylactic supplement that would intervene in the neurodegenerative pathways immediately following injury. The high demand for selenium within the central nervous system, as well as the synthesis of selenoproteins by neurons and astrocytes suggests a critical role of selenium within the brain and spinal cord. Studies were designed to test the efficacy of enriched dietary selenium status …
Regulation Of Pancreatic Β-Cell Function By The Renin-Angiotensin System In Type 2 Diabetes, Robin C. Shoemaker
Regulation Of Pancreatic Β-Cell Function By The Renin-Angiotensin System In Type 2 Diabetes, Robin C. Shoemaker
Theses and Dissertations--Pharmacology and Nutritional Sciences
Diet-induced obesity promotes type 2 diabetes (T2D). Drugs that inhibit the renin-angiotensin system (RAS) have been demonstrated in clinical trials to decrease the onset of T2D. Previously, we demonstrated that mice made obese from chronic consumption of a high-fat (HF) diet have marked elevations in systemic concentrations of angiotensin II (AngII). Pancreatic islets have been reported to possess components of the renin-angiotensin system (RAS), including angiotensin type 1a receptors (AT1aR), the primary receptor for AngII, and angiotensin converting-enzyme 2 (ACE2), which negatively regulates the RAS by catabolizing AngII to angiotensin-(1-7) (Ang-(1-7)). These two opposing proteins have been implicated in the …
Zhx2 Regulation Of Lipid Metabolism And The Balance Between Cardiovascular And Hepatic Health, Kate Townsend Creasy
Zhx2 Regulation Of Lipid Metabolism And The Balance Between Cardiovascular And Hepatic Health, Kate Townsend Creasy
Theses and Dissertations--Pharmacology and Nutritional Sciences
The growing obesity epidemic in America carries with it numerous health risks, including diabetes, increased serum lipid levels, and excess fat accumulation in the liver. If these conditions persist or become exacerbated, they may lead to the development of cardiovascular disease, the current leading cause of death among Americans, or to nonalcoholic fatty liver disease (NAFLD) which can progress to hepatocellular carcinoma (HCC), one of the deadliest forms of cancer. Better understanding of the genes involved in these diseases can lead to improved identification of at-risk individuals and treatment strategies.
Our lab previously identified zinc fingers and homeoboxes 2 (Zhx2) …
Competition’S Effect On Teacher Pay And Teacher Characteristics, Casey S. Brasher
Competition’S Effect On Teacher Pay And Teacher Characteristics, Casey S. Brasher
Theses and Dissertations--Economics
This dissertation adds to the literature that examines the effect of competition and school choice reform in elementary and secondary education. Specifically, we explore how three major forms of competition in U.S. schooling markets in Tiebout competition, charter competition, and private school competition affect the teaching profession by estimating a teacher wage equation and series of teacher characteristic equations. Since it has been well-established that all 3 forms of competition are likely endogenous, we present 2SLS estimates of competition’s effect in addition to simple OLS estimates. Our findings confirm the importance of studies controlling for endogeneity concerns, particularly in regards …

Evidence-Based Hospitals, David R. Bardach
Theses and Dissertations--Epidemiology and Biostatistics
In 2011 the University of Kentucky opened the first two inpatient floors of its new hospital. With an estimated cost of over $872 million, the new facility represents a major investment in the future of healthcare in Kentucky. This facility is outfitted with many features that were not present in the old hospital, with the expectation that they would improve the quality and efficiency of patient care. After one year of occupancy, hospital administration questioned the effectiveness of some features. Through focus groups of key stakeholders, surveys of frontline staff, and direct observational data, this dissertation evaluates the effectiveness of …
Developments In Nonparametric Regression Methods With Application To Raman Spectroscopy Analysis, Jing Guo
Developments In Nonparametric Regression Methods With Application To Raman Spectroscopy Analysis, Jing Guo
Theses and Dissertations--Epidemiology and Biostatistics
Raman spectroscopy has been successfully employed in the classification of breast pathologies involving basis spectra for chemical constituents of breast tissue and resulted in high sensitivity (94%) and specificity (96%) (Haka et al, 2005). Motivated by recent developments in nonparametric regression, in this work, we adapt stacking, boosting, and dynamic ensemble learning into a nonparametric regression framework with application to Raman spectroscopy analysis for breast cancer diagnosis. In Chapter 2, we apply compound estimation (Charnigo and Srinivasan, 2011) in Raman spectra analysis to classify normal, benign, and malignant breast tissue. We explore both the spectra profiles and their derivatives to …
Novel Role Of Intestinal Lipid Transport In Food Allergy And Cholesterol Homeostasis, Jianing Li
Novel Role Of Intestinal Lipid Transport In Food Allergy And Cholesterol Homeostasis, Jianing Li
Theses and Dissertations--Pharmacology and Nutritional Sciences
The small intestine is the main organ for food digestion and nutrient absorption. It is constantly exposed to antigen and immunomodulatory agents from diet and commensal microbiota. Thus, the intestine is the largest compartment of the immune system in the body. Peanuts and many other allergen resources contain triglycerides, which may affect the antigen absorption through the intestine, but their effects on sensitization and anaphylaxis are unknown. We found that medium chain triglycerides (MCT) promoted antigen absorption into Peyer’s Patches, rather than into the blood directly. Both gavage and feeding of MCT plus peanut protein induced spontaneous allergic sensitization. MCT-sensitized …
The Role Of Apob-Containing Lipoproteins In Abdominal Aortic Aneurysm, Jing Liu
The Role Of Apob-Containing Lipoproteins In Abdominal Aortic Aneurysm, Jing Liu
Theses and Dissertations--Pharmacology and Nutritional Sciences
Abdominal aortic aneurysm (AAA) is a devastating disease that exhibits permanent lumen expansion typically in the infrarenal aorta. AAA is prevalent among aged population, especially in males. Despite the incidence in women is lower, studies indicate the tortuosity is more severe and aortic rupture risk is higher in women. In most patients, AAA remains asymptomatic until it ruptures leading to sudden and fatal hemorrhage.
To date, there is no proven medical therapy that can prevent the expansion or rupture. Human observational studies implicate the presence of AAA is associated with both high plasma low-density lipoprotein-cholesterol (HDL-C) and low plasma high-density …
Tumor-Derived Proteins And Mitochondrial Dysfunction In Lung Cancer-Induced Cachexia, Julie B. Mclean
Tumor-Derived Proteins And Mitochondrial Dysfunction In Lung Cancer-Induced Cachexia, Julie B. Mclean
Theses and Dissertations--Physiology
Lung tumors secrete multiple factors that contribute to cachexia, a severe wasting syndrome that includes loss of muscle mass, weakness, and fatigue. 80% of advanced lung cancer patients experience cachexia, which cannot be reversed by nutritional interventions, diminishes response to and tolerance of cancer treatments, and increases morbidity and mortality. Despite a multitude of clinical trials, there are currently no approved treatments. This deficiency suggests that not all of the factors that contribute to cachexia have been identified.
Cancer is frequently accompanied by an increase in cyclooxygenase-2 (COX-2), a hallmark of inflammation. Clinical trials for COX-2 inhibitors have resulted in …
The Skeletal Muscle Molecular Clock Regulates The Timing Of Substrate Metabolism And The Circadian Expression Of Titin-Cap, Brian A. Hodge
The Skeletal Muscle Molecular Clock Regulates The Timing Of Substrate Metabolism And The Circadian Expression Of Titin-Cap, Brian A. Hodge
Theses and Dissertations--Physiology
Skeletal muscle is a major contributor to whole-body metabolism as it serves as a depot for both glucose and amino acids, and is a highly metabolically active tissue. An intrinsic molecular clock mechanism exists within skeletal muscle that regulates the timing of physiological processes. A key function of the clock is to regulate the timing of metabolic processes to anticipate time of day changes in environmental conditions. The purpose of this study was to identify metabolic genes that are expressed in a circadian manner and determine if these genes are regulated downstream of the intrinsic molecular clock by assaying gene …
Psychological Well-Being Among Breast Cancer Survivors: Factors That Influence Transition From Primary Treatment To Early Survivorship, Celestine G. Gochett
Psychological Well-Being Among Breast Cancer Survivors: Factors That Influence Transition From Primary Treatment To Early Survivorship, Celestine G. Gochett
Theses and Dissertations--Nursing
Eudaimonic psychological well-being (PWB) refers to a lifelong process of purposeful engagement in goal-driven tasks or activities resulting in positive psychological functioning. These activities reflect autonomy, purpose in life, self-acceptance, personal growth, positive relations with others, and environmental mastery. While more women are surviving breast cancer, they face a multitude of late and long term physiopsychosocial challenges that result from being diagnosed and treated. Protective health effects associated with the experience of PWB can potentially mitigate ill-being and benefit overall health of breast cancer survivors (BCS). Adequate preparation by healthcare teams to transition them from primary treatment to early survivorship …
The Impact Of Prenatal Depressive Symptoms, Intimate Partner Relationship, And Immune Status On Postpartum Depression, Julia J. Hall
The Impact Of Prenatal Depressive Symptoms, Intimate Partner Relationship, And Immune Status On Postpartum Depression, Julia J. Hall
Theses and Dissertations--Nursing
The prevalence of depression during pregnancy in the U. S. is approximately 13%. Poor quality of the intimate partner relationship is significantly correlated with depression during pregnancy. The adverse effects of antenatal depression have been widely documented. The relationship between the intimate partner relationship and depression during pregnancy has not been well delineated in the literature. Little data exist regarding the impact of prenatal immune status on risk for postpartum depression. Due to limited evidence, there is a critical need to examine the relationship among trimester specific cytokines, quality of the intimate partner relationship, and antenatal depressive symptoms on risk …
An Investigation Into The Occurrence Of Batrachochytrium Dendrobatidis Infection In Plethodontid Salamander Communities Of Robinson Forest, Sarah H. Spaulding
An Investigation Into The Occurrence Of Batrachochytrium Dendrobatidis Infection In Plethodontid Salamander Communities Of Robinson Forest, Sarah H. Spaulding
Theses and Dissertations--Forestry and Natural Resources
Environmental and anthropogenic stressors negatively affect amphibians in a variety of ways, often increasing their vulnerability to pathogen infection and mortality. Sampling for the pathogenic fungus Batrachochytrium dendrobatidis (Bd) was conducted in order to: 1) determine the presence of chytrid infection in stream-associated plethodontid salamanders of southeastern Kentucky, and 2) evaluate differences in infection intensity between salamanders residing in intact forest streams, timber-harvested streams, and surface-mined streams. During 14 sampling sessions occurring between March, April and May of 2013, DNA samples from 306 individual salamanders within 8 species from the family Plethodontidae were collected; additional amphibians (i.e. frogs, newts) were …
Invasiveness Of An Exotic Gall Wasp Is Influenced By Interactions With Exotic And Endemic Organisms, Ignazio Graziosi
Invasiveness Of An Exotic Gall Wasp Is Influenced By Interactions With Exotic And Endemic Organisms, Ignazio Graziosi
Theses and Dissertations--Entomology
American chestnut was once a crucial component of North American forests, but it was functionally eliminated by the introduction of the chestnut blight fungus. Chestnut is recently experiencing resurgence, but the introduced Asian chestnut gall wasp, a specialist herbivore, threatens chestnut recovery. I characterized this invasion and the interactions developing with host associates as the gall wasp spread in North America. Gall wasp dispersal is attributable to host plant distribution, effects of prevailing winds during adult insect emergence, and to topography. This knowledge may be useful to more accurately predict locations of future gall wasp infestations. Gall wasp invasiveness is …
Sex, Dementia, And Long-Term Care: Public Perspectives, Erin L. Yelland
Sex, Dementia, And Long-Term Care: Public Perspectives, Erin L. Yelland
Theses and Dissertations--Family Sciences
The current mixed methods study utilized an ecological framework to examine public perspectives toward sexual behaviors among long-term care residents with dementia. Analyzing attitudes of the public is an integral component of understanding the entire ecological system that affects the development and overall well-being of a long-term care resident. Attitudes were examined using a multiple segment factorial vignette with a probability sample of 329 respondents from a southern state. Results indicate that attitudes were not statistically affected by sex or the elapsed time since diagnosis, and age, spousal disposition, and degree of intimacy predicted attitudes. A respondent’s education level also …

Food Security Factors Affect Growth In Young Children In An Ecuadorian Indigenous Community, Whitney Jeannine Asher
Theses and Dissertations--Nutrition and Food Systems
Inadequate nutrition in preschool-aged children in an urban indigenous community outside of Santo Domingo, Ecuador has a negative impact on growth and development. Nutritional assessments have shown that children are underweight and that there are some effects of stunting and wasting in the population. This study was conducted to assess the extent of food security in this indigenous community in preparation for addressing two of the Millennium Development Goals for 2015: reducing the under-five child mortality rate by two-thirds and eradicating extreme poverty and hunger. An aim was to validate on-site assessment measures in this indigenous community regarding geographic circumstances, …
New Insights Into The Function And Development Of The Soldier Caste In Termites, Li Tian
New Insights Into The Function And Development Of The Soldier Caste In Termites, Li Tian
Theses and Dissertations--Entomology
The evolution of nonreproductive castes is a defining characteristic of eusociality. The function and developmental regulation of the altruistic worker and soldier caste is the central element contributing to major advantages of eusociality over solitary animals. The soldier caste is the first evolved sterile caste in termites. Their primary function is believed to be colony defense. However, the function and development of termite soldiers remains largely unknown. Because of their apparent morphological adaptation for fighting and their limited behavior repertoire, our understanding of colony defense by termite soldiers is limited to their physical defense. In addition, we know little about …
Dietary Habits And Knowledge Of College Age Students, Matthew R. Majors
Dietary Habits And Knowledge Of College Age Students, Matthew R. Majors
Theses and Dissertations--Nutrition and Food Systems
College is a time of emerging identity and habit formation for students. One hundred and sixty-two (162) college students were surveyed via an internet based survey. The survey asked questions regarding dietary habits such as consumption of dairy, vegetables, fruit, and protein. The survey also examined dietary knowledge such as ability to read food labels. The students were divided into two groups for analysis, nutrition majors and non-nutrition majors. The two groups differed in Body Mass Index (BMI) (p=0.004), but not nutrition knowledge (p=0.082). The nutrition students had an average BMI of 22.0+/-2.42 and a nutrition knowledge score of 2.44+/-0.60, …
