Subchronic Infusion Of The Product Of Inflammation Prostaglandin J2 Models Sporadic Parkinson's Disease In Mice, Sha-Ron Pierre, Marijke Am Lemmens, Maria E. Figueiredo-Pereira

Publications and Research

Background Chronic neuroinflammation is implicated in Parkinson's disease (PD). Inflammation involves the activation of microglia and astrocytes that release high levels of prostaglandins. There is a profound gap in our understanding of how cyclooxygenases and their prostaglandin products redirect cellular events to promote PD neurodegeneration. The major prostaglandin in the mammalian brain is prostaglandin D2, which readily undergoes spontaneous dehydration to generate the bioactive cyclopentenone prostaglandins of the J2 series. These J2 prostaglandins are highly reactive and neurotoxic products of inflammation shown in cellular models to impair the ubiquitin/proteasome pathway and cause the accumulation of ubiquitinated proteins. PD is a …

Examining Our Roots: How Over 100 Years Of Religion Yielded A Secular Liberal Arts Program At Ursinus College, Karen Boedecker

Religious Studies Summer Fellows

Although Ursinus College is a fairly young institution, there have been many modifications that have occurred throughout its history. While we as students might be tempted to fixate on the changes that we find most relatable such as the price of an Ursinus education (it was $188 a year in 1885) or the clubs and organizations in which one could choose to be involved (in the 1880s the only options were the Zwinglian, Schaff, Ebrard, and Olevian literary societies which flourished here), the overall character of the College was most heavily influenced by the presence and eventual absence of religion. …

Effects Of Selection For Cooperation And Attention In Dogs, Márta Gácsi, Paul Mcgreevy, Edina Kara, Ádám Miklósi

Cooperative Behavior Collection

Background: It has been suggested that the functional similarities in the socio-cognitive behaviour of dogs and humans emerged as a consequence of comparable environmental selection pressures. Here we use a novel approach to account for the facilitating effect of domestication in dogs and reveal that selection for two factors under genetic influence (visual cooperation and focused attention) may have led independently to increased comprehension of human communicational cues.

Method: In Study 1, we observed the performance of three groups of dogs in utilizing the human pointing gesture in a two-way object choice test. We compared breeds selected to work while …

A Multiplex Polymerase Chain Reaction Assay To Simultaneously Distinguish Cryptosporidium Species Of Veterinary And Public Health Concern In Cattle, Mónica Santín, Dante S. Zarlenga

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Four species of Cryptosporidium are routinely found in cattle: Cryptosporidium parvum, Cryptosporidium bovis, Cryptosporidium ryanae, and Cryptosporidium andersoni. It is important to determine the species of Cryptosporidium in infected cattle because C. parvum is the only serious pathogen for humans as well as cattle. Identification of Cryptosporidium species and genotypes currently relies on molecular methods such as polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) or gene sequencing. Incorporation of these techniques in a routine veterinary diagnostic laboratory is cost prohibitive. As such, their applications are limited primarily to research and a few public health laboratories. To …

Rapid Fixation Of Non-Native Alleles Revealed By Genome-Wide Snp Analysis Of Hybrid Tiger Salamanders, Benjamin M. Fitzpatrick, Jarrett R. Johnson, D. Kevin Kump, H. Bradley Shaffer, Jeramiah J. Smith, S. Randal Voss

Biology Faculty Publications

BACKGROUND: Hybrid zones represent valuable opportunities to observe evolution in systems that are unusually dynamic and where the potential for the origin of novelty and rapid adaptation co-occur with the potential for dysfunction. Recently initiated hybrid zones are particularly exciting evolutionary experiments because ongoing natural selection on novel genetic combinations can be studied in ecological time. Moreover, when hybrid zones involve native and introduced species, complex genetic patterns present important challenges for conservation policy. To assess variation of admixture dynamics, we scored a large panel of markers in five wild hybrid populations formed when Barred Tiger Salamanders were introduced into …

Workload And Performance Factors Associated With Multimedia Job Aids For Community Health Workers, Jose F. Florez-Arango

Dissertations and Theses (Open Access)

This dissertation focuses on factors of multimedia job aids that modify workload, protocol adherence and clinical errors in community health workers. Literature shows that community health workers performance is not acceptable even with support of paper job aids. There are cognitive theories that try to explain reasons why the performance of community health workers is poor regardless of the access to paper based-job aid. Based on cognitive science and multimedia design theories an intervention was designed to compare alternative representations for the information contained on paper job aids and the capability of this new designed job aids to enhance community …

A previously reported blood pressure (BP) quantitative trait locus on rat Chromosome 1 was isolated in a short congenic segment spanning 804.6 kb. The 804.6 kb region contained only two genes, LOC306664 and LOC306665. LOC306664 is predicted to translate into A Disintegrin-like and Metalloproteinase with Thrombospondin Motifs-16 (Adamts16). LOC306665 is a novel gene. All predicted exons of both LOC306664 and LOC306665 were sequenced. Non-synonymous variants were identified in only one of these genes, LOC306664. These variants were naturally existing polymorphisms among inbred, outbred and wild rats. The full-length rat transcript of Adamts16 was detected in multiple tissues. Similar to ADAMTS16 …

Assessment Of Pre-Pcr Whole Genome Amplification Of Single Pollen Grains Using Flowering Dogwood (Cornus Florida), Candace Dillon

Theses and Dissertations

Studies of gene flow in natural plant populations often focus on either historical or abiotic dispersal methods (e.g. wind, water, gravity), but there is little information available on contemporary, animal-mediated pollen dispersal patterns. Emerging molecular laboratory techniques allow unprecedented insights into spatial patterns of pollen-mediated gene flow. However, to date, technical challenges have limited their widespread application. The genome of a pollen grain can be amplified via whole genome amplification (WGA) prior to traditional amplification via polymerase chain reaction (PCR) to prevent the stochastic effects associated with low copy number amplification. Even still, WGA can suffer from low success rates …

Effect Of Posture On Acromiohumeral Distance With Arm Elevation In Subjects With And Without Rotator Cuff Disease Using Ultrasonography, Nitin Kalra

Theses and Dissertations

Objectives: To examine the effects of posture on subacromial (SA) space with arm elevation in patients with rotator cuff disease (RCD) and healthy subjects. Background: Poor posture has been linked to altered scapular mechanics, theorized to lead to excessive SA space narrowing. However, no study has examined the direct effects of posture on SA space using ultrasonography. We hypothesize that when compared to a neutral posture, upright posture will increase SA space and slouched posture will decrease SA space. Methods: Subjects with painful RCD (n=31) and healthy (n=29) shoulders participated. SA space was measured on ultrasound generated images using the …

Yy1'S Role In Dna Methylation Of Peg3 And Xist, Jeong Do Kim, Keunsoo Kang, Joomyeong Kim

Faculty Publications

Unusual clusters of YY1 binding sites are located within several differentially methylated regions (DMRs), including Xist, Nespas and Peg3, which all become methylated during oogenesis. In this study, we performed conditional YY1 knockdown (KD) to investigate YY1's roles in DNA methylation of these DMRs. Reduced levels of YY1 during spermatogenesis did not cause any major change in these DMRs although the same YY1 KD caused hypermethylation in these DMRs among a subset of aged mice. However, YY1 KD during oogenesis resulted in the loss of DNA methylation on Peg3 and Xist, but there were no changes on Nespas and H19. …

Behavioral And Molecular Analysis Of Individual Variation In Ethanol Drinking, Jennifer Wolstenholme

Theses and Dissertations

A majority of Americans regularly consume alcohol, but the risk factors leading to excessive drinking and alcohol abuse are unevenly distributed throughout the population. Genetic differences can account for only 40-60% of this variability. While variations in ethanol preference drinking in rodent models have been reported, the neurobiological factors underlying these behaviors are still not completely understood. Thus, these studies were designed to determine behavioral and molecular factors associated with the initiation of ethanol drinking preference in an inbred mouse model. We harnessed the power of inter-individual variation of ethanol drinking within an inbred mouse strain to essentially eliminate genetic …

The Genome Scale Metabolic Model Of Cryptosporidium Hominis: Inv209, Niti Vanee

Theses and Dissertations

The apicomplexan Cryptosporidium is a protozoan parasite of humans and other mammals. Cryptosporidium species cause acute gastro-enteritis and diarrheal disease in healthy humans and animals, and cause life-threatening infection in immuno-compromised individuals such as people with AIDS. It has a one-host life cycle and invades intestinal epithelial cells causing diarrhea, or more rarely the pulmonary epithelium. Cryptosporidium carries out all the asexual reproductive stages like several other apicomplexans. Current annotation of this organism predicts it to contain 3884 genes of which only 1581 genes have predicted functions. By using a combination of bioinformatics analysis, biochemical evidence, and high-throughput data, a …

Leadership Development Of Registered Dietitians, Anne Marie Bigley Hunter

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

This study investigated leadership development of Registered Dietitians in nationally elected or appointed leadership positions of the American Dietetic Association. An explanatory sequential mixed method design: participant selection model was used collecting qualitative data after a quantitative phase. Demographic data were collected via a mailed survey questionnaire followed by, with consent, a web based validated Sentence Completion Test International- Maturity Assessment Profile Research Version (2) (SCTi- MAP) to determine their stage of leadership development. Of the 97 participants, 86% (n=83) responded to the survey questionnaire with 92% (n=79) rating the importance of dietitians being leaders as very important; 100% (n=83) …

Adaptation At A Shortened Length In Rabbit Femoral Artery, Melissa Bednarek

Theses and Dissertations

It is well known that the overlap between the thick and thin filaments in striated muscle is responsible for the single active length-tension (L-T) curve. With the lack of visible striations, a sarcomeric unit has not been identified in smooth muscle. Though once thought to function like striated muscle via a sliding filament mechanism of contraction, recent studies on length-adaptation (L-adaptation) in airway smooth muscle (ASM), in which increased tension is generated with repeated contraction, have led to the hypothesis of a dynamic L-T curve in smooth muscle. Although more established in ASM, two studies have shown L-adaptation in vascular …

Executive Functions And Approaches To Learning: Relationships To School Readiness In Head Start Preschoolers, Virginia E. Vitiello

Open Access Dissertations

The purpose of this study was to determine whether the effects of executive functions on school readiness outcomes were mediated by approaches to learning in Head Start preschoolers. Executive functions are cognitive skills, including inhibition, cognitive flexibility, and working memory, that are involved in learning as well as regulating behavior (Blair, Granger, & Razza, 2005; Espy, McDiarmid, Cwik, Stalets, Hamby, & Senn, 2004). Approaches to learning include important learning-to-learn skills such as persistence, initiative, and motivation (Fantuzzo, Perry, & McDermott, 2004). Based on previous literature, it was hypothesized that strong executive functions would support the development of positive approaches to …

Sexual Selection In A Species With Exploded Leks: The White-Crowned Manakin (Pipra Pipra), Wendy P. Tori

Dissertations

Understanding what determines male reproductive success is central to sexual selection theory. The main goal of this dissertation was to examine the processes that shape female mate choice and male reproductive success in an exploded lek species: the White-crowned Manakin (Pipra pipra). The first chapter examined if females select males with certain genetic characteristics to gain indirect fitness benefits. Specifically, it tested whether females preferentially mate with unrelated males or males with high overall heterozygosity to increase the genetic diversity of their offspring. The second chapter examined if food resources within territories affect male mating success of territory …

Chinese Regional Agricultural Productivity: 1994-2005, Haizhi Tong, Lilyan E. Fulginiti, Juan P. Sesmero

Lilyan E. Fulginiti Publications

Agricultural productivity growth in Chinese provinces during the 1994-2005 period is examined using two alternative approaches: a parametric stochastic frontier and a non-parametric Malmquist index. These models are suitable to the Chinese situation due to the existence of procurement prices, quotas, and other interventions that have distorted prices. Results show that there is high but declining productivity growth rates in the mid 1990’s with productivity growth decreasing in the late 1990’s but with a reversal of the trend around 1998 when growth rates start accelerating. A stochastic frontier translog production function is estimated to obtain an alternative measure of total …

P2x Antagonists Inhibit Styryl Dye Entry Into Hair Cells, M. A. Crumling, M. Tong, K. L. Aschenbach, L. Liu

University Faculty Publications and Creative Works

The styryl pyridinium dyes, FM1-43 and AM1-43, are fluorescent molecules that can permeate the mechanotransduction channels of hair cells, the sensory receptors of the inner ear. When these dyes are applied to hair cells, they enter the cytoplasm rapidly, resulting in a readily detectable intracellular fluorescence that is often used as a molecular indication of mechanotransduction channel activity. However, such dyes can also permeate the ATP receptor, P2X2. Therefore, we explored the contribution of P2X receptors to the loading of hair cells with AM1-43. The chick inner ear was found to express P2X receptors and to release ATP, similar to …

An Amazing Open, And An Obscenity In Arlington, Richard C. Crepeau

On Sport and Society

If you watched The Open from Turnberry this weekend there were two surprises: Tiger Woods didn’t make the cut and Tom Watson nearly won the tournament. It became obvious that Tiger wasn’t playing his A-game when in the middle of his second round he played himself out of the tournament. Woods was one under par after seven holes and then went bogey, bogey, double bogey, par, bogey, double bogey. He was hitting shots that any weekend duffer could relate to as he topped the ball, mishit the ball several times, and explored all of the varieties of the rough. It …
