Synthesis And Conjugation Of Terminal Α-Galactose Containing, Roger Allan Ashmus

Open Access Theses & Dissertations

Over 16 million people in Latin America are infected with the protozoan parasite Trypanosoma cruzi (T. cruzi), the causative agent of Chagas disease, and up to 50,000 infected people die annually due to complications during the chronic stage of the disease. To date, there are no vaccines or effective drugs to treat chronic Chagas disease. It is known that T. cruzi contains cell surface mucin-like glycoproteins with terminal α-galactosyl residues, and it is well established that they are highly immunogenic. The exact structure of the immunogenic carbohydrate epitopes, however, remains unknown. To determine which epitopes have the ability to interact …

Sodium Hydroxide Pretreatment And Enzymatic Hydrolysis Of Coastal Bermuda Grass, Ziyu Wang, Deepak R. Keshwani, Arthur P. Redding, Jay J. Cheng

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Coastal Bermuda grass was pretreated with NaOH at concentrations from 0.5% to 3% (w/v) for a residence time from 15 to 90 minutes at 121 °C. The pretreatments were evaluated based on total lignin removal and production of total reducing sugars, glucose and xylose from enzymatic hydrolysis of the pretreated biomass. Up to 86% lignin removal was observed. The optimal NaOH pretreatment conditions at 121 °C for total reducing sugars production as well as glucose and xylose yields are 15 minutes and 0.75% NaOH. Under these optimal pretreatment conditions, total reducing sugars yield was about 71% of the theoretical maximum, …

Cosmological Beliefs About Origins Related To Science Achievement Among Junior High-School Students In South Bend, Indiana, J. David Van Dyke

Dissertations

Problem. American high-school students score lower in science achievement tests than their peers in other developed nations. The Organization for Economic Cooperation and Development (OECD) ranked the scientific achievement of American high-school students as ―very low‖ in comparison to high-school students in other industrialized nations—only 29th out of 57 developed countries. Research has indicated that achievement declines as U.S. students progress to higher grades and take on more rigorous science courses. A variety of factors have been documented that may account for U.S. students‘ lower science achievement rankings. These include socioeconomic status, race, and gender. One area only marginally …

Where Cultures And Sovereigns Collide: Balancing Federalism, Tribal Self-Determination, And Individual Rights In The Adoption Of Indian Children By Gays And Lesbians, Steve Sanders

Articles by Maurer Faculty

This article analyzes the complex interplay between adoption (traditionally a matter reserved to state family law) and the federal Indian Child Welfare Act in the context of adoptions by gays and lesbians.

As a federal statute that partially preempts state law for the benefit of Native Americans, ICWA implicates three sovereigns: the United States, the state where the adoption petition is brought, and the tribe whose child is the focus of the proceeding. This interplay of sovereigns in itself makes Indian child welfare law complicated and interesting. Beyond these sovereign interests, also to be considered are the interests and rights …

Increased Perfusion And Angiogenesis In A Hindlimb Ischemia Model With Plasmid Fgf-2 Delivered By Noninvasive Electroporation, B. Ferraro, Y. L. Cruz, M. Baldwin, D. Coppola, R. Heller

Bioelectrics Publications

Gene therapy approaches delivering fibroblast growth factor-2 (FGF-2) have shown promise as a potential treatment for increasing blood flow to ischemic limbs. Currently, effective noninvasive techniques to deliver plasmids encoding genes of therapeutic interest, such as FGF-2, are limited. We sought to determine if intradermal injection of plasmid DNA encoding FGF-2 (pFGF) followed by noninvasive cutaneous electroporation (pFGFE+) could increase blood flow and angiogenesis in a rat model of hindlimb ischemia. pFGFE+ or control treatments were administered on postoperative day 0. Compared to injection of pFGF alone (pFGFE-), delivery of pFGFE+ significantly increased FGF-2 expression for 10 days. Further, the …

School Psychologists' Confidence Level With Suicide Intervention And Prevention In The Schools, Jodi L. Stein-Erichsen

PCOM Psychology Dissertations

Schools psychologists are often called upon to work with suicidal students regardless of previous training or the comfort levels that they possess in this area (Debski, Spadafore, Jacob, Poole, and Hixon, 2007; Oordt, Jobes, Fonseca, and Schmidt, 2009). This study evaluates the results of a survey created by this study’s investigator. It was disseminated to members of the National Association of School Psychologists’ Listserv (NASP-Listserv) and gathers general and demographic data as well as information that contribute to the assessment of suicide intervention and prevention experience and training received by the participants. Also investigated was whether or not suicide intervention …

Gender Differences In Symptom Presentation Of Sexually Abused African American Children Ages 8 Through 12, Tania Czarnecki Wismar

PCOM Psychology Dissertations

A well-documented connection exists between child sexual abuse and psychological symptoms that may persist into adulthood. Because of the significant public health implications of child sexual abuse, it is critical to examine the many variables related to such a potentially traumatic event, including its psychological effects and effects on gender, so that treatment providers are able to gain a better understanding of how males and females are affected by their abuse experiences. This study examined the role of gender on psychological symptoms in a largely understudied population of inner city African American children; it also examined gender roles regarding the …

Improving Validity Of Referrals For Comprehensive Autism Evaluation : A Tier-2 Direct Autism Observation Checklist, Mary Heim Elberson

PCOM Psychology Dissertations

Early identification of autism has received national attention and can lead to positive treatment outcomes. Research has demonstrated that qualitative impairments in social and communicative behaviors can be detected within the first two years of life. Unfortunately, many children with autism will not receive an autism diagnosis until they enter preschool. Professionals within school settings have not often received extensive training on assessment of autism spectrum disorders. Expectations, however, are that school-based teams can identify students who demonstrate characteristics associated with autism and refer those students for a comprehensive autism evaluation. Currently, autism screening tools are limited to rating scales …

The Relevance Of Executive Functions In Academic Production In Middle School, Norina Bobik

PCOM Psychology Dissertations

The present study investigated the role that executive function plays on academic production in middle school from a prototype perspective. It was hypothesized that middle school teachers' prototypical ratings of the executive function capacities of middle school students who are academically successful would differ significantly from these same middle school teachers' prototypical ratings of the executive function capacities of middle school students who are academically unsuccessful. The study used archival data consisting of items from the Behavior Rating Inventory of Executive Function (BRIEF), a questionnaire that was completed by middle school teachers during a professional in-service workshop at four large …

An Examination Of Academic Resilience Among High-Achieving Hispanic-American Male Inner City Adolescents, Aida A. Ismael-Lennon

PCOM Psychology Dissertations

Identifying risk and protective factors has been at the cornerstone in resilience research in education. Although this focus has contributed to our understanding of the personal traits inherent in academically resilient students, it fails to expound relationships existing outside of the individual. This study aims to uncover the interrelationship between individual characteristics and the environments that help create academic resilience. Twelve Hispanic-American male inner-city at-risk students, considered resilient, were interviewed about perceived factors leading to their academic success. A qualitative analysis was used to analyze the data, using Strauss & Corbin's (1998) Grounded Theory Approach. The themes that emerged were …

Spirituality As A Mediator In The Relationship Between Self-Care Practices And Perceived Stress Levels Among Lutheran Clergy, David W. Brant

PCOM Psychology Dissertations

There is currently a shortage of ordained ministers to fill the current vacancies in Lutheran churches due, in part, to the multiplicity of pastoral roles, the stressors clergy encounter in their vocation, and poor self-care. This exploratory research found a statistically significant, small, negative relationship when examining the relationship between clergy self-care practices and perceived levels of stress. The research did not support a relationship between clergy self-care practices and perceived levels of stress when mediated by clergy spiritual maturity. Other predictor variables such as first vocation, gender, spousal financial contributions and stress also did not yield statistically significant results …

A Comparison Of The Parenting Dimensions That Lead To Positive Social Problem Solving In The Children From Traditional Versus Children From Same-Sex Parent Families, Karen Joan Taratuski

PCOM Psychology Dissertations

Building social competence is an important task of childhood. Effective social problem solving is a vital skill in the development of social competence. Although there are myriad factors that influence a child’s learning of social problem solving skills, the quality of the interaction between parents and children has been found to be a pivotal influence. Although much research focuses on the effects of parenting in the context of a traditional family (two parents of opposite gender), little more than half of all children are living in this type of family. Same-sex parent households draw particular criticism. However, research suggests that …

Hypnosis As An Effective Treatment For Hot Flashes From Naturally Occurring Menopause, Carol F. Oliver

PCOM Psychology Dissertations

Hot flashes are a significant problem for many women with naturally occurring menopause and can cause physical symptoms as well as a decreased quality of life. In the past women were treated with hormonal replacement therapy. However, recent research has shown that the risks may outweigh the benefits. In addition, nontraditional nutritional treatments, such as herbal supplements, are not approved by the Food and Drug Administration, and often, the exact amount of the substance contained in each dose cannot be guaranteed. Many women and their doctors are looking for an alternative treatment. The use of hypnosis has been shown to …

Characterization Of Soil Carbon Stabilization In Long-Term Row-Cropped Agro-Ecosystems, Soraya Patricia Alvarado-Ochoa

University of Kentucky Doctoral Dissertations

Soil organic matter (SOM) is a dynamic soil property, sensitive and responsive to many factors. The possibility of increasing soil carbon (C) sequestration by changing land use and management practices has been of great interest recently due to concerns with global changes in the atmospheric carbon dioxide (CO₂) balance. Nonetheless, as a result of the complex dynamics of SOM, there is still the need for SOM characterization procedures capable of monitoring SOM stabilization, taking into account all the factors involved.

This study characterized SOM stabilization as affected by management practices in three long-term field experiments, considering physical, chemical …

Targeted Polymeric Biomaterials For The Prevention Of Post Surgical Adhesions, John M. Medley

Based on an understanding of the biochemical events that lead to PSA formation, a series of targeted polymeric biomaterials was designed to interrupt the fibrin gel matrix propagation and suppress PSA formation.

Using group transfer polymerization, a series of well controlled block copolymers of polyacrylic acid and poly(ethylene glycol-methacrylate) based materials was synthesized. Subsequent functionalization …

Modulation Of The Alpha-7 Nicotinic Acetylcholine Receptor Following Experimental Rat Brain Injury Improves Cellular And Behavioral Outcomes, Thomas Matt Woodcock

University of Kentucky Doctoral Dissertations

Traumatic brain injury (TBI) is a leading cause of death and long-term disability worldwide, and survivors are often left with cognitive deficits and significant problems with day to day tasks. To date, therapeutic pharmacological treatments of TBI remain elusive despite numerous clinical trials. An improved understanding of the molecular and cellular response to injury may help guide future treatment strategies. One promising marker for brain injury is the translocator protein (TSPO), which is normally expressed at a low level, but is highly expressed following brain damage and is associated with neuroinflammation. The isoquinoline carboxamide PK11195 binds selectively to the TSPO …

The No. 5 Block In Eastern Kentucky: A Critical Re-Examination Of The Petrology With Special Attention To The Origin Of Inertinite Macerals In The Splint Lithotypes, Allison Ranae Richardson

University of Kentucky Master's Theses

Microbes, including fungi and bacteria, and insects are responsible for the consumption and subsequent degradation of plant materials into humus. These microbes directly and indirectly affect the physical and chemical characteristics of coal macerals. Efforts to understand and determine the origins of inertinite macerals are largely misrepresented in the literature, conforming to a single origin of fire. This study focuses on the variability of physical and inferred chemical differences observed petrographically between the different inertinite macerals and discusses the multiple pathways plant material may take to form and or degrade these macerals.

Petrographic results show that fungal activity plays a …

Spiny amaranth is a problematic weed of heavily grazed pastures in Kentucky and surrounding states. The first objective was to evaluate spiny amaranth control when herbicides are applied before and after emergence. Spiny amaranth seed collected in 2008 were seeded in rows in the fall (November) and the following spring (March) in fields located near Lexington and Princeton, KY. Treatments consisted of five application dates and five herbicides plus an untreated control arranged in a split-split plot design. The following parameters were measured: fresh weight, plant height and percent visual control. At both locations pendimethalin applied in November, March and …

Impact Of High-Input Production Practices On Soybean Yield, Daniel L. Jordan

University of Kentucky Master's Theses

High-input management practices are often heavily marketed to producers to increase soybean [Glycine max (L) Merr.] yield in already high-yielding environments. Field research was conducted in three locations within 6 states (Arkansas, Iowa, Kentucky, Louisiana, Michigan, and Minnesota) in 2009 to determine the effect of seed treatment, inoculant, foliar fungicide, additional soil fertility beyond state recommendations, foliar fertilizer, increased population over state recommendations, and narrow row spacing on yield. The high-input system (combination of the management practices) yielded higher than standard-input system (University recommended management practices) in only 8 of the 18 locations. Narrow rows, in both the high …
