Characterisation Of The Human Thyroid Peroxidase Gene Mutations (S) In Patients With Congenital Dyshormonogenetic Hypothyroidism / Lee Ching Chin, Ching Chin Lee

Student Works (2010-2019)

Congenital hypothyroidism (CH) is a public health concern affecting 1 / 3000 - 4000 newborn babies. In reference to this, thyroid peroxidase (TPO) abnormality, typically inherited as autosomal recessive traits was found to be one of the causes of dyshormonogenetic CH. Our group had previously identified a homozygous c.1159G>A mutation in exon 8 of the TPO gene of CHP41. In this study, the TPO gene of CHP41’s family members was screened for the c.1159G>A mutation and the results showed that all family members carried the same mutation either in homozygous or heterozygous forms. In addition, another 20 unrelated …


The Conservation Of Biodiversity In Malaysia: Options For An Integrative Statutory Framework / Sarah Aziz Abdul Ghani Aziz, Abdul Ghani Aziz Sarah Aziz Jan 2013

The Conservation Of Biodiversity In Malaysia: Options For An Integrative Statutory Framework / Sarah Aziz Abdul Ghani Aziz, Abdul Ghani Aziz Sarah Aziz

Student Works (2010-2019)

This thesis lies hinged on the conclusion embedded in the National Biodiversity Policy 1998 (“NBP”), that there is no single comprehensive legislation in Malaysia which relates to biological diversity conservation and management as a whole. The NBP goes on to state that the existing legislative framework is sectoral, to an extent restrictive causing some deficiencies, due to an absence of an ntegrative approach across sectors, lacking consideration of the overall objectives of conservation and comprehensive coverage of biological diversity issues. This stems from the provisions of the Constitution of Malaysia 1957 which has unwittingly led to legislative non-uniformity.


Collaborative Justice: An Analysis Of The Use Of "Justice" In The Writings Of Lisa Sowle Cahill, Dennis W. Feltwell Jan 2013

Collaborative Justice: An Analysis Of The Use Of "Justice" In The Writings Of Lisa Sowle Cahill, Dennis W. Feltwell

Electronic Theses and Dissertations

This dissertation explores the role of justice in the writings of Catholic ethicist Lisa Sowle Cahill. Since 1990, Cahill has supported theological voices participating in the public forum, which she describes as a meeting ground for diverse intellectual and religious traditions. Good argumentation is necessary but not sufficient to resolve ethical dilemmas within the politically liberal context in which Cahill makes her claims. Instead, her commitment to justice underwrites those narratives and practices which demand one's fullest possible participation in contributing toward the common good. Cahill's notion of justice develops correlatively to the degree that she integrates the principles of …

The Ethical Imagination: A Hermeneutical Study, Jeb Gordon Jungwirth Jan 2013

The Ethical Imagination: A Hermeneutical Study, Jeb Gordon Jungwirth

Electronic Theses and Dissertations

This research examines and describes the ways psychotherapists address ethical dilemmas through a hermeneutic analysis of how they responded to a portrayal of a therapy session represented in a television series. Interview transcripts were analyzed and assessed for both how therapists navigate difficult ethical terrain, and upon what, thematically, they tend to direct their thought and concern. Moreover, particular consideration is given to the role of imagination in the development of ethical meaning, intention, and understanding in the clinical context, which intersects with a critique of the American Psychological Association's ethics code and its underlying philosophical assumptions. Such theoretical underpinnings …


Psychotherapy As Constitutional Practice: A Detailed Interaction Analysis Of The Change Process In Psychotherapy, Cody L. Maddox Jan 2013

Psychotherapy As Constitutional Practice: A Detailed Interaction Analysis Of The Change Process In Psychotherapy, Cody L. Maddox

Electronic Theses and Dissertations

Psychotherapy is concerned with changing individuals: it is a practice devoted to the constitution of certain kinds of subjects. Although the various therapeutic schools have their own explanations of psychotherapeutic change, more empirical work needs to be dedicated to understanding how this process takes place. In this study, a fine grain research methodology is used to produce an account of the change process that occurred over the course of two psychotherapy sessions. The data consists of naturally occurring video recordings of a single therapist and client dyad. The goal of this research is to examine the relationship of mutual formation …


Theological Foundations For An Ethics Of Cosmocentric Transfiguration: Navigating The Eco-Theological Poles Of Conservation, Transfiguration, Anthropocentrism, And Cosmocentrism With Regard To The Relationship Between Humans And Individual Nonhuman Animals, Ryan Patrick Mclaughlin Jan 2013

Theological Foundations For An Ethics Of Cosmocentric Transfiguration: Navigating The Eco-Theological Poles Of Conservation, Transfiguration, Anthropocentrism, And Cosmocentrism With Regard To The Relationship Between Humans And Individual Nonhuman Animals, Ryan Patrick Mclaughlin

Electronic Theses and Dissertations

In the past forty years, there has been an unprecedented explosion of theological writings regarding the place of the nonhuman creation in ethics. The purpose of this dissertation is to propose a taxonomy of four paradigms of eco-theological thought that will categorize these writings and facilitate the identification, situation, and constructive development of the paradigm of cosmocentric transfiguration. This taxonomy takes shape within the tensions of three theological foundations: cosmology, anthropology, and eschatology. These tensions establish two categorical distinctions between, on the one hand, conservation and transfiguration, and, on the other, anthropocentrism and cosmocentrism. The variations within these poles yield …

Metalated Nitriles: Ligand Exchange And Copper-Catalyzed Reactions, Dinesh Nath Jan 2013

Metalated Nitriles: Ligand Exchange And Copper-Catalyzed Reactions, Dinesh Nath

Electronic Theses and Dissertations

This thesis describes new methods of carbon-carbon bond formation using metalated nitriles generated via metal exchange reactions. Sulfinylnitriles undergo a sulfinyl-metal exchange to yield lithiated, magnesiated and zincated nitriles, which can trap a range of electrophiles. The sulfinyl-metal exchange is effective with vinylic, quaternary and tertiary substitution patterns and addresses the long-standing problem of alkylating secondary nitriles. This method was then further extended to other oxidation states of sulfur, namely sulfonyl-metal exchange and relatively unknown sulfide-metal exchange. The sulfide metal exchange overcomes the problem related to the propensity of highly substituted sulfinylnitriles to eliminate. Sulfide-metal exchange is synthetically attractive because …

The Effect Of L-Dopa And Natural Products On Age-Related Motor Deficits And Dopaminergic Cell Survival, Erika Nicole Allen Jan 2013

The Effect Of L-Dopa And Natural Products On Age-Related Motor Deficits And Dopaminergic Cell Survival, Erika Nicole Allen

Electronic Theses and Dissertations

With age, there is a loss of motor coordination leading to an increase in falls. Currently, there are limited therapeutic regimens for age-related motor deficits. However, L-DOPA is used for motor dysfunction in Parkinson's disease (PD). Therefore, we investigated the effect of L-DOPA on motor deficits in young (2 mo) and old (20 mo) mice. We found that L-DOPA reversed age-related motor decline.

Chronic L-DOPA use produces involuntary movements or dyskinesias. Interestingly, natural foods, such as wild blueberries (WBB), and isolated compounds, such as resveratrol and pinostilbene, have beneficial effects on several physiological processes with few side effects. Therefore, to …


Differential Expressions Of Nodal-Signal Transducers And Global Transcriptional Repression Commit Vegetal Cells In Eleutherodactylus Coqui To Form Nutritional Endoderm, Suman Chatterjee Jan 2013

Differential Expressions Of Nodal-Signal Transducers And Global Transcriptional Repression Commit Vegetal Cells In Eleutherodactylus Coqui To Form Nutritional Endoderm, Suman Chatterjee

Electronic Theses and Dissertations

The vegetal core cells of a Xenopus laevis embryo commit to mesendoderm via the Nodal-signaling pathway. In Eleutherodactylus coqui, a direct developing frog, mesendoderm is specified at the marginal zone of the early gastrulae and vegetal core cells transform into nutritional endoderm. It is a novel tissue consisting of transient, yolk rich cells that provide nutrition, but do not differentiate into adult tissues. We hypothesized that a disruption of Nodal-signaling is responsible for committing vegetal core cells to nutritional endoderm. I report a dual regulation involved in the generation of nutritional endoderm. First, differential expression of Nodal-signaling components like Smad2 …

Bioactive Glass Scaffolds For The Regeneration Of Load-Bearing Bone, Xin Liu

Doctoral Dissertations

"Biocompatible scaffolds that replicate the structure and function of bone would be ideal bone substitutes for structural bone loss, provided they have the requisite mechanical properties for reliable long-term loading. In this dissertation, strong porous scaffolds of silicate 13-93 bioactive glass, created with two different microstructures, were evaluated to determine their mechanical properties and their capacity to regenerate bone in a rat calvarial defect model. Scaffolds with an oriented microstructure of columnar pores were prepared by unidirectional freezing of camphene-based suspensions, followed by thermal annealing and sintering. By optimizing the freezing conditions, annealing time, and sintering temperature, constructs (porosity = …


Social-Context Based Routing And Security In Delay Tolerant Networks, Roy A. Cabaniss Jan 2013

Social-Context Based Routing And Security In Delay Tolerant Networks, Roy A. Cabaniss

Doctoral Dissertations

"Delay Tolerant Networks (DTNs) were originally intended for interplanetary communications and have been applied to a series of difficult environments: wireless sensor networks, unmanned aerial vehicles, and short-range personal communications. There is a class of such environments in which nodes follow semi-predictable social patterns, such as wildlife tracking or personal devices. This work introduces a series of algorithms designed to identify the social patterns present in these environments and apply this data to difficult problems, such as efficient message routing and content distribution. Security is also difficult in a mobile environment. This is especially the case in the event that …


Effect Of Dense Heat Exchanging Internals On The Hydrodynamics Of Bubble Column Reactors Using Non-Invasive Measurement Techniques, Mohammed Khloofh Al Mesfer Jan 2013

Effect Of Dense Heat Exchanging Internals On The Hydrodynamics Of Bubble Column Reactors Using Non-Invasive Measurement Techniques, Mohammed Khloofh Al Mesfer

Doctoral Dissertations

"Given their efficiency and capital cost reduction, bubble/slurry bubble column reactors are the reactors of choice for Fischer-Tropsch (FT) synthesis, offering clean alternative fuels and chemicals. FT synthesis is an exothermic process that requires many heat exchanging tubes in order to remove heat efficiently and maintain the desired temperature and isothermal operating condition. The impact of the heat exchanging tubes (internals) on the hydrodynamics is not fully understood. Reliably designing and scaling up bubble column reactors requires proper understanding of hydrodynamics, as well as heat and mass transfer parameters.

The main objective of this work is to advance the understanding …

Critical Comparison Of Intravenous Injection Of Tio2 Nanoparticles With Waterborne And Dietary Exposures Concludes Minimal Environmentally-Relevant Toxicity In Juvenile Rainbow Trout Oncorhynchus Mykiss., D Boyle, Ga Al-Bairuty, Tb Henry, Rd Handy

School of Biological and Marine Sciences

A critical comparison of studies that have investigated tissue accumulation and toxicity of TiO2-NPs in fish is necessary to resolve inconsistencies. The present study used identical TiO2-NPs, toxicological endpoints, and fish (juvenile rainbow trout Oncorhynchus mykiss) as previous studies that investigated waterborne and dietary toxicity of TiO2-NPs, and conducted a critical comparison of results after intravenous caudal-vein injection of 50 μg of TiO2-NPs and bulk TiO2. Injected TiO2-NPs accumulated only in kidney (94% of measured Ti) and to a lesser extent in spleen; and injected bulk TiO2 was found only in kidney. No toxicity of TiO2 was observed in kidney, …

Nuclear Translocation Of Cardiac G Protein-Coupled Receptor Kinase 5 Downstream Of Select Gq-Activating Hypertrophic Ligands Is A Calmodulin-Dependent Process., Jessica I Gold, Jeffrey S Martini, Jonathan Hullmann, Erhe Gao, J Kurt Chuprun, Linda Lee, Douglas G Tilley, Joseph E Rabinowitz, Julie Bossuyt, Donald M Bers, Walter J. Koch

Department of Medicine Faculty Papers

G protein-Coupled Receptors (GPCRs) kinases (GRKs) play a crucial role in regulating cardiac hypertrophy. Recent data from our lab has shown that, following ventricular pressure overload, GRK5, a primary cardiac GRK, facilitates maladaptive myocyte growth via novel nuclear localization. In the nucleus, GRK5's newly discovered kinase activity on histone deacetylase 5 induces hypertrophic gene transcription. The mechanisms governing the nuclear targeting of GRK5 are unknown. We report here that GRK5 nuclear accumulation is dependent on Ca(2+)/calmodulin (CaM) binding to a specific site within the amino terminus of GRK5 and this interaction occurs after selective activation of hypertrophic Gq-coupled receptors. Stimulation …

Modeling Undesirable Factors In Efficiency Evaluation With An Application To The Malaysian Manufacturing Sector / Noor Asiah Bt Ramli, Noor Asiah Ramli Jan 2013

Modeling Undesirable Factors In Efficiency Evaluation With An Application To The Malaysian Manufacturing Sector / Noor Asiah Bt Ramli, Noor Asiah Ramli

Student Works (2010-2019)

Efficiency measurement must reflect the realities of production activities. In the manufacturing sector, emissions from fossil fuel combustion, which are acknowledged as being undesirable outputs, should be taken into account in efficiency measurement, since they are produced jointly with desirable outputs. This type of measurement is referred to as eco-efficiency. To analyze eco-efficiency, the Directional Distance Function (DDF) has been a popular approach. However, there is a drawback to the DDF model where the direction vector to the production boundary is fixed arbitrarily, and, hence, may not provide the best efficiency measures. The main purpose of this study is twofold. …

Toxinological Characterizations Of The Venom Of Hump-Nosed Pit Viper (Hypnale Hypnale) / Tan Choo Hock, Choo Hock Tan

Student Works (2010-2019)

Hump-nosed pit viper (Hypnale hypnale) is a medically important snake in Sri Lanka and Western Ghats of India. Envenomation by this snake still lacks effective antivenom clinically. The species is also often misidentified, resulting in inappropriate treatment. The median lethal dose (LD50) of H. hypnale venom varies from 0.9 μg/g intravenously to 13.7 μg/g intramuscularly in mice. The venom shows procoagulant, hemorrhagic, necrotic, and various enzymatic activities including those of proteases, phospholipases A2 and L-amino acid oxidases which have been partially purified. The monovalent Malayan pit viper antivenom and Hemato polyvalent antivenom (HPA) from Thailand effectively cross-neutralized the venom’s lethality …
