The Effect Of Two Types Of Recovery On The Decline In Performance After Intense Bouts Of Exercise, Whitney Shindelar

Honors Program Theses

Anyone who is recreationally active, whether an athlete or someone in the general population, has some preferred action they choose to engage in after an extensive bout of intense exercise. According to Comparison of Two Strategies on Recovery after Exhausting Exercise, the common recommendation of raising your arms above your head in order to recover more quickly and thoroughly has been shown to not be the optimal recovery mechanism. The previously mentioned study has recently shown that a subject's heart rate decreased dramatically faster, which then decreased their over all recovery time, when they opted to bend at the …

Multiple Forms Of Atypical Rearrangements Generating Supernumerary Derivative Chromosome 15., Nicholas J Wang, Alexander S Parokonny, Karen N Thatcher, Jennette Driscoll, Barbara M Malone, Naghmeh Dorrani, Marian Sigman, Janine M Lasalle, N Carolyn Schanen

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Maternally-derived duplications that include the imprinted region on the proximal long arm of chromosome 15 underlie a complex neurobehavioral disorder characterized by cognitive impairment, seizures and a substantial risk for autism spectrum disorders1. The duplications most often take the form of a supernumerary pseudodicentric derivative chromosome 15 [der(15)] that has been called inverted duplication 15 or isodicentric 15 [idic(15)], although interstitial rearrangements also occur. Similar to the deletions found in most cases of Angelman and Prader Willi syndrome, the duplications appear to be mediated by unequal homologous recombination involving low copy repeats (LCR) that are found clustered in the …

Temporal And Functional Profile Of The Transcriptional Regulatory Network In The Early Regenerative Response To Partial Hepatectomy In The Rat., Egle Juskeviciute, Rajanikanth Vadigepalli, Jan B Hoek

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: The goal of these studies was to characterize the transcriptional network regulating changes in gene expression in the remnant liver of the rat after 70% partial hepatectomy (PHx) during the early phase response including the transition of hepatocytes from the quiescent (G0) state and the onset of the G1 phase of the cell cycle. RESULTS: The transcriptome of remnant livers was monitored at 1, 2, 4, and 6 hours after PHx using cDNA microarrays. Differentially regulated genes were grouped into six clusters according their temporal expression profiles. Promoter regions of genes in these clusters were examined for shared transcription …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

INTRODUCTION: Hemophagocytic lymphohistiocytosis is an immune-mediated syndrome that typically has a rapidly progressive course that can result in pancytopenia, coagulopathy, multi-system organ failure and death. CASE PRESENTATION: A 57-year-old Caucasian woman was referred in fulminant hemophagocytic lymphohistiocytosis, with fever, pancytopenia, splenomegaly, mental status changes and respiratory failure. She was found to have stage IV classical Hodgkin lymphoma, in addition to Epstein-Barr virus and cytomegalovirus viremia. Her presentation was preceded by a 3-year prodrome consisting of cytopenia and fever that were partially controlled by steroids and azathioprine. CONCLUSION: Fulminant hemophagocytic lymphohistiocytosis may follow a prodromal phase that possesses features suggestive of …

Transcriptional Regulatory Network Analysis During Epithelial-Mesenchymal Transformation Of Retinal Pigment Epithelium., Craig H Pratt, Rajanikanth Vadigepalli, Praveen Chakravarthula, Gregory E Gonye, Nancy J Philp, Gerald B Grunwald

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

PURPOSE: Phenotypic transformation of retinal pigment epithelial (RPE) cells contributes to the onset and progression of ocular proliferative disorders such as proliferative vitreoretinopathy (PVR). The formation of epiretinal membranes in PVR may involve an epithelial-mesenchymal transformation (EMT) of RPE cells as part of an aberrant wound healing response. While the underlying mechanism remains unclear, this likely involves changes in RPE cell gene expression under the control of specific transcription factors (TFs). Thus, the purpose of the present study was to identify TFs that may play a role in this process.

METHODS: Regulatory regions of genes that are differentially regulated during …

Theoretical Substruction Illustrated By The Theory Of Learned Resourcefulness (Article), Abir K. Bekhet, Jaclene A. Zauszniewski

College of Nursing Faculty Research and Publications

This article describes the process of theoretical substruction and uses this process to examine the significance of Rosenbaum's resourcefulness theory for nursing research and practice. The article discusses relocation as a phenomenon of interest to gero-psychiatric nurses working with elders who have relocated to retirement communities, illustrated by the theory of learned resourcefulness. The literature was reviewed to assess the congruence between the theoretical and operational systems suggested by Rosenbaum's resourcefulness theory. A model of learned resourcefulness is presented that includes middle-range concepts, relational statements, and propositions derived from the research literature. Theoretical substruction provides a mechanism for testing middle-range …

Sense Of Coherence And Quality Of Life In Women Family Members Of The Seriously Mentally Ill, M. Jane Suresky, Jaclene Zauszniewski, Abir K. Bekhet

College of Nursing Faculty Research and Publications

Providing care to a family member with serious mental illness (SMI) can reduce a family's quality of life. Quality of life, however, can be positively influenced by the caregiver's sense of coherence (SOC). Antonovsky's Salutogenic Health Model was examined in this secondary analysis of data from 60 women family members of adults with SMI. The results indicated that greater perceived stress decreased SOC and QoL, greater SOC enhanced QoL, and SOC partially mediated the effects of perceived stress on QoL. The findings suggest the need for reducing stress and strengthening SOC to promote optimal QoL for family members of adults …

The Community Of Nursing: Moral Friends, Moral Strangers, Moral Family, Carolyn A. Laabs

College of Nursing Faculty Research and Publications

Unlike bioethicists who contend that there is a morality common to all, H. Tristan Engelhardt (1996) argues that, in a pluralistic secular society, any morality that does exist is loosely connected, lacks substantive moral content, is based on the principle of permission and, thus, is a morality between moral strangers. This, says Engelhardt, stands in contrast to a substance-full morality that exists between moral friends, a morality in which moral content is based on shared beliefs and values and exists in communities that tend to be closely knit and religiously based. Of what value does Engelhardt’s description of ethics as …

Teaching Social Justice Using A Pedagogy Of Engagement, Ruth Ann Belknap

College of Nursing Faculty Research and Publications

Teaching an undergraduate level diversity course with a health focus requires specific teaching methods. A pedagogy of engagement provides an effective strategy for exploring issues of race, class, gender, and structural inequalities that underlie health disparities. Engagement learning enhances understanding of theories of oppression and liberation presented in the course and highlights social justice issues.

Crossing Borders In Search Of The Mother-Daughter Story: Interdependence Across Time And Distance, Ruth Ann Belknap

College of Nursing Faculty Research and Publications

Although studies have identified the importance of the mother–daughter relationship and of familism in Mexican culture, there is little in the literature about the mother–daughter experience after daughters have migrated to the United States. This study explores relationships between three daughters in America and their mothers in Mexico, and describes ways in which interdependence between mothers and daughters can be maintained when they are separated by borders and distance. Data collection included prolonged engagement with participants, field notes, and tape-recorded interviews. Narrative analysis techniques were used. Findings suggest mother–daughter interdependence remains. Some aspects may change, but the mother–daughter connection continues …

List Composition Effects For Masked Semantic Primes: Evidence Inconsistent With Activation Accounts, Jennifer C. Major

Theses and Dissertations (Comprehensive)

Priming is the benefit that an event receives when its processing has been preceded by the processing of a related or identical event. Context effects on priming are evident when priming changes as a function of some feature of experimental trials. The most commonly explored context effect is that of relatedness proportion (RP), where it has often been shown that the magnitude of priming (semantic or repetition) is directly related to the proportion of related trials: Increasing the related trials results in greater priming. Although previously thought to depend on strategic processing, recent evidence of context effects from designs using …

Access To Medical Records For Research Purposes: Varying Perceptions Across Research Ethics Boards, Donald Willison, Claudia Emerson, Karen Szala-Meneok, Elaine Gibson, Lisa Schwartz, Karen Weisbaum, François Fournier, Kevin Brazil, Michael Coughlin

Articles, Book Chapters, & Popular Press

Variation across research ethics boards (REBs) in conditions placed on access to medical records for research purposes raises concerns around negative impacts on research quality and on human subject protection, including privacy. Aim: To study variation in REB consent requirements for retrospective chart review and who may have access to the medical record for data abstraction. Methods: Thirty 90-min face-to-face interviews were conducted with REB chairs and administrators affiliated with faculties of medicine in Canadian universities, using structured questions around a case study with open-ended responses. Interviews were recorded, transcribed and coded manually. Results: Fourteen sites (47%) required individual patient …

A Public At Risk: Personal Fitness Trainers Without A Standard Of Care, Margaret E. Ciccolella, J. Mark Van Ness, Tommy Boone

College of the Pacific Faculty Articles

In 2002, an overweight, sedentary, and middle-aged man suffered a heart attack during his first workout with his “certified” personal trainer. During the workout, the man repeatedly asked to stop because he was experiencing fatigue, heat, thirst, breathlessness, and chest pain. The trainer responded to requests to stop and complaints of fatigue by questioning his client’s masculinity and by continuing the workout. In the lawsuit that followed (Rostai v. Neste Enterprises, 2006), the court did not have the option to consider a statutorily defined standard of care since no licensing requirements existed for those who design and/or lead fitness programs. …

Tissue Engineering The Motoneuron To Muscle Segment Of The Stretch Reflex Arc Circuit Utilizing Micro-Fabrication, Interface Design And Defined Medium Formulation, Mainak Das

Electronic Theses and Dissertations

The stretch reflex circuit is one of the most primitive circuits of mammalian system and serves mainly to control the length of the muscle. It consists of four elements: the stretch sensor (muscle spindle/ intrafusal fiber lie parallel between extrafusal, contractile musculature), extrafusal muscle fiber, sensory neuron and motoneuron. The basic principle of the stretch reflex arc circuit is as follows: whenever there is a sudden stretch in a muscle, it needs to compensate back to its original length so as to prevent any kind of injury. It performs this compensation process using a simple negative feed back circuit called …

The Effect Of Pparγ Activation By Pioglitazone On The Lipopolysaccharide-Induced Pge2 And No Production: Potentialunderlying Alteration Of Signaling Transduction, Bin Xing

University of Kentucky Doctoral Dissertations

Microglia-mediated neuroinflammation plays an important role in the pathogenesis of Parkinson's disease (PD). Uncontrolled microglia activation produces major proinflammatory factors including cyclooxygenase 2 (COX-2) and inducible nitric oxide synthase (iNOS) that may cause dopaminergic neurodegeneration. Peroxisome proliferator-activated receptor γ (PPARγ) agonist pioglitazone has potent antiinflammatory property. We hypothesize pioglitazone protects dopaminergic neuron from lipopolysaccharide (LPS)-induced neurotoxicity by interacting with relevant signal pathways, inhibiting microglial activation and decreasing inflammatory mediators.

First, the neuroprotection of pioglitazone was explored. Second, the signaling transductions such as jun N-terminal kinase (JNK) and the interference with these pathways by pioglitazone were investigated. Third, the effect of …

Design, Synthesis, And Pharmacological Evaluation Of A Series Of Novel, Guanidine And Amidine-Containing Neonicotinoid-Like Analogs Of Nicotine: Subtype-Selective Interactions At Neuronal Nicotinic-Acetylcholine Receptor., Aaron Joseph Haubner

University of Kentucky Doctoral Dissertations

The current project examined the ability of a novel series of guandine and amidine-containing nicotine analogs to interact with several native and recombinantlyexpressed mammalian neuronal nicotinic-acetylcholine receptor (nAChR) subtypes. Rational drug design methods and parallel organic synthesis was used to generate a library of guanidine-containing nicotine (NIC) analogs (AH compounds). A smaller series of amidine-containing nicotine analogs (JC compounds) were also synthesized. In total, >150 compounds were examined. Compounds were first assayed for affinity in a high-throughput [³H]epibatidine radioligand-binding screen. Lead compounds were evaluated in subtype-selective binding experiments to probe for affinity at the α₄β_{2 …}

Endothelial Cell Dysfunction By Environmental Contaminants, Elizabeth Grace Oesterling

University of Kentucky Doctoral Dissertations

Within the last few decades, epidemiological evidence has linked exposure to air pollution, both its particles and its organic components, with cardiovascular disease (CVD) progression. CVD is a life long disease with the disruption of the endothelium being the inaugural event in this inflammatory process. The vascular endothelium is extremely susceptible to environmental insults given its tremendous surface area and that it is in constant contact with blood and components circulating within the blood, including xenobiotics. The endothelium is important as a barrier from blood constituents however, dysfunction of this barrier leads to the influx of lymphocytes and granulocytes that …

Translational Regulatory Mechanisms Of The Rat And Human Multidrug Resistance Protein 2, Yuanyuan Zhang

University of Kentucky Doctoral Dissertations

Multidrug resistance protein 2 (MRP2) is the second member the C subfamily in the superfamily of adenosine triphosphate (ATP)-binding cassette (ABC) efflux transporters. MRP2 is a critical player for generation of bile acidindependent bile flow and biliary excretion of glutathione, glucuronate and sulfate conjugates of endo- and xenobiotics. Dysfunctional expression of MRP2 is associated with Dubin-Johnson Syndrome.

Pathological and physiological states or xenobiotics change the MRP2 expression level. Under some conditions, expression of the human MRP2 and rat Mrp2 proteins are regulated at the translation level. There are several transcription initiation sites in MRP2/Mrp2 gene. The 5’ untranslated regions (5’UTRs) …

Genetic Regulation Of Hematopoietic Stem Cell Aging, Erin J. Oakley

University of Kentucky Doctoral Dissertations

It is well documented that both quantitative and qualitative changes in the murine hematopoietic stem cell (HSC) population occur with age. In mice, the effect of aging on stem cells is highly strain-specific, thus suggesting genetic regulation plays a role in HSC aging. In C57BL/6 (B6) mice, the HSC population steadily increases with age, whereas in DBA/2 (D2) mice, this population declines. Our lab has previously mapped a quantitative trait locus (QTL) to murine chromosome 2 that is associated with the variation in frequency of HSCs between aged B6 and D2 mice. In these dissertation studies, I first aim to …

Regulation Of L-Type Voltage-Dependnet Calcium Channels By The Rem Gtpase, Chunyan Pang

University of Kentucky Doctoral Dissertations

The Rem, Rem2, Rad, and Gem/Kir GTPases, comprise a novel subfamily of the small Ras-related GTP-binding proteins known as the RGK GTPases, and have been shown to function as potent negative regulators of high voltage-activated (HVA) Ca²⁺ channels upon overexpression. HVA Ca²⁺ channels modulate Ca²⁺ influx in response to membrane depolarization to regulate a wide variety of cellular functions and they minimally consist of a pore-forming α1 subunit, an intracellular β subunit, and a transmembrane complex α₂/δ subunit. While the mechanisms underlying RGK-mediated Ca²⁺ channel regulation remain poorly defined, it appears that both membrane …

A Novel Class Of Immunoproteasome Catalytic Subunit Lmp2 Inhibitor And Its Therapeutic Potentials In Cancer, Yik Khuan (Abby) Ho

University of Kentucky Doctoral Dissertations

The immunoproteasome, known to play an important role in MHC class I antigen processing and presentation, have been linked to neurodegenerative diseases and hematological cancers. However, the pathophysiological functions of the immunoproteasome in these diseases are still not very well established. This can be attributed mainly to the lack of appropriate molecular probes that selectively target the immunoproteasome catalytic subunits. Herein, we report the development of a small molecular inhibitor (AM) that selectively targets the major catalytic subunit, LMP2, of the immunoproteasome. We show that the compound covalently modifies the LMP2 subunit with high specificity in human prostate …

A Study Of The Distribution And Abundance Of The Adult Malaria Vector In Western Kenya Highlands, Li Li, Ling Bian, Guiyun Yan

Political Science & Geography Faculty Publications

Background: A sharp rise in the malaria mortality rate has been observed recently in western Kenya. Malaria is transmitted by mosquito vectors. Malaria control strategies can be more successful if the distribution and abundance of mosquito vectors is predicted. However, how mosquito vectors are distributed in space remain poor understood, and this question is rarely studied using spatial methods. This study aims to provide a better understanding of the distribution and abundance of mosquito vectors. To achieve this objective, spatial and non-spatial methods were employed. The data on the distribution of adult mosquitoes, and mosquito breeding habitats in a study …

Proteomic Profiling Of Endorepellin Angiostatic Activity On Human Endothelial Cells., Jason J Zoeller, Renato V Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Endorepellin, the C-terminal domain V of the heparan sulfate proteoglycan perlecan, exhibits powerful and targeted anti-angiogenic activity on endothelial cells. To identify proteins involved with endorepellin anti-angiogenic action, we performed an extensive comparative proteomic analysis between vehicle- and endorepellin-treated human endothelial cells. RESULTS: Proteomic analysis of endorepellin influence on human umbilical vein endothelial cells identified five differentially expressed proteins, three of which (beta-actin, calreticulin, and chaperonin/Hsp60) were down-regulated and two of which (vimentin and the beta subunit of prolyl 4-hydroxylase also known as protein disulfide isomerase) were up-regulated in response to endorepellin treatment-and associated with a fold change (endorepellin/control) …

Materials and Methods: Lymphoblastoid cell lines were established from one type I and two type III SMA patients. Following treatment of the cell lines by HDAC inhibitors, the levels of survival motor neuron 2 (SMN2) gene full length (fl-SMN2) transcripts were assessed by both standard and real time RT-PCR. To determine the levels of SMN protein, Western blot analysis was performed. Results: …

Highly Elevated Adenosine Deaminase Level In Brucellar Pleural Effusion, Mustafa Kasim Karahocagi̇l, Hayretti̇n Akdeni̇z, Azi̇z Dursun Kirikçi, Hasan Karsen, Bünyami̇n Sertoğullari

Turkish Journal of Medical Sciences

Pleural involvement is a rare presentation of brucellosis. There are only a few case reports in the literature presenting with pleural involvement due to brucellosis. In this report, we present a case with exudative pleural fluid first considered as tuberculous pleurisy due to lymphocyte predominance and elevated level of pleural adenosine deaminase, but later diagnosed as brucella pleurisy with positive serologic and microbiologic test results. In conclusion, in the differential diagnosis of pleurisies, routine serologic and bacteriologic methods appear to be more important than pleural adenosine deaminase elevation, especially in regions endemic for both tuberculosis and brucellosis.

A Personal Ethics Responsibility Example: The Relationship Between Child Development And Drugs Taken By Pregnant Mother, Çağatay Üstün, Özge Özgürler

Turkish Journal of Medical Sciences

Personal responsibility is an important ethical concept. The pregnant mother should regard this concept as of prime importance. The pregnant mother should take some precautions in order to protect her own health and that of her baby in order to provide for its normal development. In this communication, we address the general effects of medications or drugs ingested by a pregnant mother on the baby. Thus, we target refinement of the personal ethic responsibility of the mothers.
