Transcription And Rna Interference In The Formation Of Heterochromatin, Shiv Grewal, Sarah C.R. Elgin

Biology Faculty Research

Transcription in heterochromatin seems to be an oxymoron--surely the 'silenced' form of chromatin should not be transcribed. But there have been frequent reports of low-level transcription in heterochromatic regions, and several hundred genes are found in these regions in Drosophila. Most strikingly, recent investigations implicate RNA interference mechanisms in targeting and maintaining heterochromatin, and these mechanisms are inherently dependent on transcription. Silencing of chromatin might involve trans-acting sources of the crucial small RNAs that carry out RNA interference, but in some cases, transcription of the region to be silenced seems to be required--an apparent contradiction.

Female Curiosities: Sarah Bernhardt, Rachilde And The Use Of Spectacle In The Gaining Of Fame In Late Nineteenth-Century France, Amy Marie Harris

All-Inclusive List of Electronic Theses and Dissertations

During the late nineteenth century rapid modernization, the liberalization of the press and theatre, as well as the proliferation of photography brought about the impetus for the development of a celebrity-driven mass media. Two women who would come to fame during this era, Sarah Bernhardt and Rachilde, utilized these innovations to create spectacular public personas which emphasized each woman's idiosyncrasies while confounding notions of gender. With her dramatic performances, extravagant publicity stunts and countless world tours Bernhardt became synonymous with the promise of progress in late-nineteenth century France; while Rachilde utilized the mass media in order to create a bizarre …

Antibacterial Activity Of Positive And Negative Polarity Low-Voltage Pulsed Current (Lvpc) On Six Typical Gram-Positive And Gram-Negative Bacterial Pathogens Of Chronic Wounds, Georg Daeschlein, Ojan Assadian, Luther C. Kloth, Christina Meinl, Frank Ney, Axel Kramer

Physical Therapy Faculty Research and Publications

The positive effect of electrical stimulation (ES) on wound healing has been shown in vitro and in vivo. On the basis of increased blood flow, protein denaturation, and stimulation of cellular defense, an antibacterial effect of ES is to be expected. Although the antibacterial effect of ES already has been demonstrated in vitro, little attention has been paid to the direct antibacterial effect of changing polarity of the applied current. The aim of this study was to investigate the antibacterial effect of positive and negative monophasic low-voltage pulsed current on typical Gram-positive and Gram-negative pathogens of chronic wounds. Using the …

Metallothionein Receptor Expression In Leukocytes, Kirsten Frostad

Honors Scholar Theses

Metallothionein (MT) represents a family of low molecular weight, cysteine-rich proteins that play a number of roles in cellular homeostasis. MT is synthesized as a consequence of a variety of cellular stressors, including exposure to toxic metals, increased temperature, tissue wounding, as well as inflammatory and tumorigenic agents. This protein has been found in both intracellular compartments and extracellular spaces, and its function may depend in part on its location. Extracellular MT is able to redistribute heavy metals between tissues, act as a powerful antioxidant, affect cell proliferation, and cause the suppression of T-dependent humoral immunity. The nature of the …

Long-Term Unemployed Men: A Social Constructionist Exploration Of Identity Construction, Elizabeth A. Scott

Theses

Identity construction in long-term unemployed men over the age of thirty-five was explored using discursive psychological analysis (Wetherell, 2001). Forty participants in County Kerry, who had not engaged with statutory agencies providing employment rehabilitation services, were accessed over a three year period in order to identify the reasons for nonengagement. A grounded theory approach (Bryman, 2004) to data collection was utilised. This yielded six broad codes and eighteen categories of discursive resource drawn upon by the men in constructing identities. In explaining their continued absence from the workforce and lack of engagement with services, discourses identified by Levitas (2004) classifying …

A Lakota/Nakota/Dakota Model Of Oratory, Cheryl A. Long Feather

Theses and Dissertations

Lakota/Nakota/Dakota people, as well as other Native American tribal groups, did not traditionally use the established, conventional forms of oration to which most in contemporary mainstream society relate. Rather, Native-specific epistemology, ontology and axiology played a central role in forming and supporting the function of communication as well as the speaking conventions that continue to be used today. These culturally-based patterns and structures present both challenges and opportunities that have been only marginally explored in various disciplines such as education, social and behavioral science, and psychology. This body of work exists for the purpose of exploring a traditionally Native understanding …

Evaluation Of Osseointegration Between Two Different Modalities Of Hydroxyapatite Implant Surface Coatings: Plasma Sprayed Ha Coated Implants And Electrophoresis Deposited Nano Ha Coated Implants, Audrey Marie Selecman

Biological Sciences: Faculty Publications

Disturbance may cause community composition across sites to become more or less homogenous, depending on the importance of different processes involved in community assembly. In north-eastern North America and Europe local (alpha) diversity of forest plants is lower in forests growing on former agricultural fields (recent forests) than in older (ancient) forests, but little is known about the influence of land-use history on the degree of compositional differentiation among sites (beta diversity). Here we analyse data from 1446 sites in ancient and recent forests across 11 different landscapes in north-eastern North America and Europe to demonstrate decreases in beta diversity …

From Pagan To Christian: An Archaeological Study Of The Transformation Of Corinth In Late Antiquity, Eli J. Weaverdyck

Classical Mediterranean and Middle East Honors Projects

This thesis examines the process by which Christianity became the dominant religion of Corinth as evidenced in the archaeological record. I compare the evidence in Corinth to historical evidence for the Eastern Roman Empire, including imperial legislation and evidence for Christianization in five other eastern cities. I conclude that, in order for Christianity to supplant paganism as the dominant religion in ancient society, it had to accept many of the institutions and traditions of paganism. My investigation of the archaeological evidence in Corinth, specifically the monumental architecture, the sculpture, and the cemeteries, reveals the same phenomenon in Corinth.

Memory T Cells And The Endothelium In Allograft Rejection, Stephen Lawrence Shiao

Yale Medicine Thesis Digital Library

Organ transplantation has become increasingly important as a treatment for many human diseases. Despite the dramatic improvements in immunosuppression in recent years, acute and chronic rejection remain significant problems. It has become increasingly evident that the presence of T cell memory correlates with both acute and chronic rejection episodes. Endothelial cells (EC) have been shown to preferentially activate memory T cells and, as the lining of every transplanted organ, they are in a unique position to provide signals to alloreactive memory T cells. EC activation of memory T cells depends in part on the costimulatory molecule LFA-3 in addition to …

Effects Of Microgravity Cardiovascular Functions, Keegan Smiley

Theses (Pre-2016)

Although micro gravity means tiny or reduced gravity, it is a term frequently 􁪽􁪽., applied to label a state of free-fall within a gravitational field in which a comparison is made between the decreasing weight of an object and its stationary weight on Earth. The cardiovascular system undergoes several adaptations during spaceflight as the effects of microgravity allow fluids inside the body to redistribute. This activity is known as a "fluid shift" and is distinguished by a shift in the flow of blood and fluids toward the head. The results of this "fluid shift" are visible in astronauts exhibiting a …

The Effects Of Uranyl Acetate On Oxidative Stress Mediated Signaling On Skin Cells, Tylithia L. Burks

Theses (Pre-2016)

Skin is one of the primary targets for exposure to uranium in the work place through contact in contaminated environments. It is for this reason that the following study is undertaken to investigate the toxic effects of uranyl acetate (UA) in human BJ Foreskin cells. The objective of this study is to analyze the signaling pathway resulting in oxidative stress induced inhibition of cell proliferation by uranyl acetate in BJ Foreskin. The hypothesis is that a dose of 1 mM of uranyl acetate will approximately decrease cell proliferation by 50% compared to control cells. Uranyl acetate is a water-soluble compound …

The Effects Of Microgravity On Liver Function In Mouse, Monique Shuler

Theses (Pre-2016)

The environment of space is one that is currently of great interest to researchers. With so little known concerning microgravity and radiation, both areas pose a particular interest in regards to living organisms. Microgravity is a term commonly applied to a condition of free-fall within a gravitational field in which the weight of an object is reduced compared to its weight at rest on Earth. Upon exposure, the body undergoes numerous changes, especially at the cellular level. Evidence has shown conclusively that many of these effects increase in severity when space travel is extended to long term. Several studies carried …

Behavioral Adaptability Of Calling In A Species Of Cricket (Orthoptera: Anastostomatidae) Based On An Increase In Interference From A Heterospecific Natural Chorus In San Luis, Costa Rica, May 2007, Lee Kaiser

Monteverde Institute: Tropical Ecology and Conservation

Orthoptera are among the first musicians on earth, and the deep evolutionary history of crickets involving acoustics has allowed them to greatly develop systems to produce and process such sensory information. This study attempts to contribute to the knowledge base of cricket behavioral biology through observation of changes in call characteristics of a species of cricket based on an induced increase in heterospecific natural chorus complexity in San Luis, Costa Rica. A chorus recording was used to induce such an increase in the complexity of the acoustic surroundings of the studied cricket in order to gain insight into how their …
