Extracellular Matrix Based Substrates For Propagation Of Human Pluripotent Stem Cells, Sheena Abraham Feb 2010

Extracellular Matrix Based Substrates For Propagation Of Human Pluripotent Stem Cells, Sheena Abraham

Theses and Dissertations

In human pluripotent stem cell (hPSC) research and applications, the need for a culture system devoid of non-human components is crucial. Such a system should exhibit characteristics observed in conventional culture systems that have used mouse embryonic fibroblast feeders for hPSC self renewal without the requirement of excessive supplementation with growth factors. To achieve this, we focused on the identification and characterization of extracellular matrix (ECM) substrates for hPSC propagation. ECM substrates derived from mouse and human fibroblasts were assessed for their ability to support self-renewal of hPSCs. Characterization of hPSCs on ECM-based substrates demonstrated maintenance of pluripotent characteristics based …


Recapitulating Osteoblastogenesis With Electrospun Fibrinogen Nanofibers And Adipose Stem Cells And Electrospinning Adipose Tissue-Derived Basement Membrane, Michael Francis Feb 2010

Recapitulating Osteoblastogenesis With Electrospun Fibrinogen Nanofibers And Adipose Stem Cells And Electrospinning Adipose Tissue-Derived Basement Membrane, Michael Francis

Theses and Dissertations

To repair, replace, or regenerate damaged or diseased tissue has been a long-standing, albeit elusive, goal in medical research. Here, we characterize patient-derivable mesenchymal stem cell types, termed adipose-derived stem cells (ASCs). These cells, which can be derived from liposuction fat and lipoaspirate saline, are sources for patient-derivable extracellular matrix (ECM), fibrinogen (Fg) and adipose tissue extracellular matrix, and may prove useful for synthesizing new bone tissue analogues in vitro. Traditionally and rapidly isolated ASCs were thoroughly characterized as multipotent, having osteogenic, adipogenic, and chondrogenic differentiation potential, and they exhibited comparable proliferative lifespans. These ASCs also shared an indistinguishable immunophenotype …

Graph-Based Global Illumination, Brian C. Ricks Jan 2010

Graph-Based Global Illumination, Brian C. Ricks

Theses and Dissertations

The slow render times of global illumination algorithms make them impractical in most commercial and academic settings. We propose a novel framework for calculating the computational complexity of global illumination algorithms and show that no other recent improvements have reduced this complexity. We further show that many algorithms use a tree as their rendering paradigm. We propose a new rendering algorithm, pipe casting, which calculates light paths using a graph instead of a tree. Pipe casting significantly reduces both computational complexity and actual render time of rendering. Using an L2 pixel-wise error comparison, on average our algorithm can render a …

Terra Australis Incognita During The Age Of Exploration: A Window Into The Changing European World View, Adam Aaron Marshall Jan 2010

Terra Australis Incognita During The Age Of Exploration: A Window Into The Changing European World View, Adam Aaron Marshall

Theses and Dissertations

For nearly two millennia some Europeans believed that a vast, wealthy, and peopled continent, Terra Australis Incognita, lay in the southern ocean, and acted as a stabilizing counterweight to the northern landmasses. The presence of this frontier, if only imaginary, represented geographical opportunity, and served as a psychological safety valve. Until discoverers possessed the ability to accurately chart the southern seas, the existence of the theoretical continent went unchallenged. Two voyagers serve as bookends in this search during the Age of Exploration: Pedro Ferdinand de Quirós (1565-1615), and Captain James Cook (1728-1779). Beyond their actual voyages, these men serve as …


The Role Of The Ca2+-Dependent Protein Kinase, Camk-Ii, In Heart And Kidney Development In The Zebrafish, Danio Rerio, Sarah Rothschild Jan 2010

The Role Of The Ca2+-Dependent Protein Kinase, Camk-Ii, In Heart And Kidney Development In The Zebrafish, Danio Rerio, Sarah Rothschild

Theses and Dissertations

Ca2+/calmodulin-dependent protein kinase type II (CaMK-II) is a multifunctional serine/threonine kinase that is ubiquitously expressed throughout the lifespan of metazoans. Mammals encode four genes (α, β, γ, δ) that generate over forty splice-variants. CaMK-II is important in a myriad of functions, including ion channel regulation, cell-cycle progression, and long term potentiation. In adults, alterations in activation of CaMK-II induce cardiac arrhythmias and heart failure. Developmental roles for CaMK-II are not as well understood since mouse knockouts are embryonic lethal. Therefore the identification of other vertebrate CaMK-II genes will add to our understanding of development. Zebrafish encode seven catalytically active CaMK-II …


Role Of Oxidative Reactive Species And Antioxidants In Metabolism And Transport Of Therapeutic Drugs, Svetlana Verenich Jan 2010

Role Of Oxidative Reactive Species And Antioxidants In Metabolism And Transport Of Therapeutic Drugs, Svetlana Verenich

Theses and Dissertations

Oxidative stress (OS) is a frequent complication of various disease conditions such as Alzheimer’s and Parkinson’s disease, atherosclerosis, preeclampsia, rheumatoid arthritis, diabetes including gestational diabetes, etc. OS is defined as an imbalance between the production of reactive species and the ability of an organism to detoxify the reactive intermediates and repair the damage. As a result of OS, the excess of reactive species such as oxygen superoxide (O2-), hydroxyl radical (OH), peroxynitrite (ONOO−), 4-hydroxynonenal (4HNE), etc., have a tendency to react with nearby proteins/nucleic acids/lipids changing their functionality or inactivating them completely. The organism has many ways to protect itself …


Autotaxin: A Regulator Of Oligodendrocyte Differentiation, Larra Yuelling Jan 2010

Autotaxin: A Regulator Of Oligodendrocyte Differentiation, Larra Yuelling

Theses and Dissertations

In order for oligodendrocyte progenitor cells (OPCs) to differentiate into fully mature, myelinating oligodendrocytes, they must be specified at the correct times and undergo coordinated changes in both gene expression and morphology. As oligodendrocytes differentiate, they transition from a bipolar morphology into a morphology characterized by a complex network of multiple processes, which will eventually generate membranous structures necessary for myelination of axonal segments. As changes are observed in cellular morphology, oligodendrocytes also undergo changes in their gene expression profile and express genes necessary for both early and later stages of development such as olig1 and myelin basic protein (mbp), …

Historically Informed Performance Practice Of The Baroque Era, Amanda Beard Jan 2010

Historically Informed Performance Practice Of The Baroque Era, Amanda Beard

Theses and Dissertations

In recent years, much debate has ensued regarding the level of consideration that should be given to the historical context of musical compositions that were written and performed during the Baroque era, which extends from 1600 to 1750 CE. The question arises as to how closely we should strive to emulate the performance conditions that would have been present during the Baroque era. Robert Donington, an English musicologist and author of two definitive texts on Baroque performance practice, suggests in his Performer's Guide to Baroque Music that we can meet the expectations of the Baroque composers to a greater degree …

Indian Psychology: The Connection Between Mind, Body, And The Universe, Sandeep Atwal Jan 2010

Indian Psychology: The Connection Between Mind, Body, And The Universe, Sandeep Atwal

Theses and Dissertations

The purpose of this study was to devise a mode of treatment that would be helpful when clinically working with the East Indian community. A theoretical orientation of Indian psychology was describes using the principles found in various Hindu scriptures. The scriptures show that an unbalance and a disconnection from the true self causes psychological problems and as the individual comes in contact with the true self the psychological problems are eliminated. Different theories for understanding the human psyche are used to describe this process: the triguna theory, the kosha theory, Ayurveda, and Patanjali's Yoga. These different theories work together …


Positive Psychology And The Jewish Holiday Calendar: A Resource Manual For Small Groups, Tami Krichiver Jan 2010

Positive Psychology And The Jewish Holiday Calendar: A Resource Manual For Small Groups, Tami Krichiver

Theses and Dissertations

Research indicates the Jewish community could benefit from additional resources aimed at supporting the psychospiritual needs of community members. While clergy and mental health professionals often collaborate to address these needs, there is no model that utilizes psychologists in a non-clinical setting for the purpose of integrating common positive psychology and spiritual concepts. The literature reveals many commonalities between positive psychology strengths and Jewish holiday themes. The purpose of this study was to develop a resource manual for psychologists and rabbis. The primary aims of the manual were to (a) utilize positive psychology to enhance psychospiritual development within the Jewish …
