The Root Of Dental Anatomy: A Case For Naming Eustachius The "Father Of Dental Anatomy"., Gregory W. Bennett Jan 2009

The Root Of Dental Anatomy: A Case For Naming Eustachius The "Father Of Dental Anatomy"., Gregory W. Bennett

Journal Articles: College of Dentistry

When one considers the names of those whose affect on dentistry reached far beyond their lifetimes, one may think of Fauchard, Wells, Morton and Black. One name that deserves to be called among the pantheon of the greats is Bartholomaeus Eustachius. Eustachius was not the first to study the anatomy of the teeth and jaws, having been preceded by Da Vinci; however, he was the first to publish a treatise devoted entirely to this subject, Libellus de Dentibus, in 1563. As Sir William Osler, the father of modern medicine, stated: "In Science, the credit goes to the man who convinces …

Elevated Expression Of L-Selectin Ligand In Lymph Node-Derived Human Prostate Cancer Cells Correlates With Increased Tumorigenicity., Prakash Radhakrishnan, Ming-Fong Lin, Pi-Wan Cheng Jan 2009

Elevated Expression Of L-Selectin Ligand In Lymph Node-Derived Human Prostate Cancer Cells Correlates With Increased Tumorigenicity., Prakash Radhakrishnan, Ming-Fong Lin, Pi-Wan Cheng

Journal Articles: Biochemistry & Molecular Biology

Human prostate cancer LNCaP cells including C-33 and C-81 cells were originally derived from the lymph nodes of a patient with metastatic prostate cancer. These two cells were employed for characterization of L-selectin ligand and in vitro tumorigenicity, because they mimic the clinical conditions of early and late-stage human prostate cancer. C-81 cells exhibit higher in vitro migratory and invasive properties as compared with C-33 cells. We find that the L-selectin ligand and mucin glycan-associated MECA-79 epitope were elevated in C-81 cells. An increase of these glycotopes positively correlates with elevated tumorigenicity and expression of key glycosyl- and sulfotransferase genes. …

Steroid Analysis By Ph-Mediated Stacking Mekc, Liliya Bykova Jan 2009

Steroid Analysis By Ph-Mediated Stacking Mekc, Liliya Bykova

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation is based on research that led to the development and application of capillary electrophoresis method for the analysis of sex steroid hormones in the blood or plasma of fish species. The analysis of steroid hormones is essential to reveal chemical compounds that are suspected in endocrine disruption, but it is challenging due to the similarity of the chemical structures of steroids, their low concentrations, and limited volumes of plasma or blood samples in fish available for analysis. There is therefore an acute need to develop reliable accurate and systematic analytical methods applicable for the analysis of structurally similar …

Ecological Responses Of Streams To Anthropogenic Stressors, And Watershed Cause-Effect Modeling In The Mid-Atlantic Highlands Region Of The United States, Yushun Chen Jan 2009

Ecological Responses Of Streams To Anthropogenic Stressors, And Watershed Cause-Effect Modeling In The Mid-Atlantic Highlands Region Of The United States, Yushun Chen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Urban sprawl and related habitat disturbance and acidic deposition are major anthropogenic stressors in the Mid-Atlantic Highlands region of the United States. Little information is available about the impacts of these stressors and cause-effect relationships between these watershed stressors and stream biotic/abiotic conditions in this region. A 10-year study (1997-2006) in the Lost River watershed and a 6-year study (2002-2007) in a South Branch Potomac River watershed were conducted to assess the impacts of Corridor H highway construction on stream biotic and abiotic conditions. Also, a three-decade study (1980-2006) using data from 5 wet deposition stations and 21 major stream …

Novel Methods For Producing Cellulose Nanocrystals From Lignocellulosic Materials And Cellulose Nanocrystals Reinforced Polymer Nanocomposites, Paul Busumafi Filson Jan 2009

Novel Methods For Producing Cellulose Nanocrystals From Lignocellulosic Materials And Cellulose Nanocrystals Reinforced Polymer Nanocomposites, Paul Busumafi Filson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cellulose nanocrystals (nanofibers) represent a new emerging biological source of reinforcing biofillers. In this dissertation, we report the results of a study to produce cellulose nanocrystals from recycled pulp, hardwood and pine dissolving pulps using maleic acid, ultrasonic-assisted (sono-chemical treatment) and enzyme-mediated hydrolysis followed by fragmentation of cellulose crystallites using ultrasonic treatment. Additionally, the effect of two modes of heating: conventional and microwave, on enzyme-mediated and maleic acid hydrolysis were investigated. Cellulose nanocrystals yields from maleic acid hydrolysis of lignocellulosic materials were lower than that obtained from endoglucanase mediated hydrolysis of lignocellulosic materials. Sonochemical treatment of lignocellulosic materials produced both …

State-Wide Fish Tissue Contaminants Survey And Effects Of Feeding Type, Season And Gender On Fish Tissue Contamination Levels, Kenneth L. Stewart Jan 2009

State-Wide Fish Tissue Contaminants Survey And Effects Of Feeding Type, Season And Gender On Fish Tissue Contamination Levels, Kenneth L. Stewart

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fish tissue fillets from benthic, predator, and mixed diet species were collected from 24 different watersheds in West Virginia. Composite samples were prepared from three to six fish fillets collected at each site, and concentrations of the chemical contaminants polychlorinated biphenyls (PCBs) and mercury were determined for each composite sample. Differences in contaminant concentrations among three major categories of feeding type (predator, benthic, and mixed diet) were examined. Differences due to species of fish and among watersheds were also examined. Predators had significantly higher mercury concentrations than benthic or mixed diet feeders and benthic feeding fish had significantly higher PCB …

Linking Land Use With Climate Change And Sustainability Topped State Legislative Land Use Reform Agenda In 2008, Patricia E. Salkin Jan 2009

Linking Land Use With Climate Change And Sustainability Topped State Legislative Land Use Reform Agenda In 2008, Patricia E. Salkin

Scholarly Works

Linking land use with climate change and sustainability topped state legislative land use reform agenda in 2008. The only discernible state land use reform trends in 2008 have focused primarily on themes surrounding sustainability. Many states pursued statutory reforms to address the strong linkages between land use and climate change, green development and affordable housing. Only one state, Michigan, focused on recodification of its planning and zoning enabling acts.

Mechanism(S) Of 3-Trifluoromethyl-4-Nitrophenol (Tfm) Toxicity In Sea Lamprey (Petromyzon Marinus) & Rainbow Trout (Oncorhynchus Mykiss), Oana Birceanu Jan 2009

Mechanism(S) Of 3-Trifluoromethyl-4-Nitrophenol (Tfm) Toxicity In Sea Lamprey (Petromyzon Marinus) & Rainbow Trout (Oncorhynchus Mykiss), Oana Birceanu

Theses and Dissertations (Comprehensive)

The pesticide, 3-trifluoromethyl-4-nitrophenol (TFM), has been extensively used over the last 50 years to control invasive sea lamprey (P. marinus) populations in the Great Lakes, but its mechanism of toxicity is unresolved. Due to its structural similarity to phenolic compounds known to inhibit mitochondrial ATP production, one hypothesis on the mode of action of TFM is that it impairs mitochondrial oxidative phosphorylation. A second hypothesis is that TFM targets the gill, interfering with gill ion uptake. Exposure of larval sea lamprey and rainbow trout (O. mykiss), to each animal’s respective 12-h TFM LC50, resulted in marked …

Invasive Litter, Not An Invasive Insectivore, Determines Invertebrate Communities In Hawaiian Forests, N. C. Tuttle, Karen H. Beard, W. C. Pitt Jan 2009

Invasive Litter, Not An Invasive Insectivore, Determines Invertebrate Communities In Hawaiian Forests, N. C. Tuttle, Karen H. Beard, W. C. Pitt

Wildland Resources Faculty Publications

In Hawaii, invasive plants have the ability to alter litter-based food chains because they often have litter traits that differ from native species. Additionally, abundant invasive predators, especially those representing new trophic levels, can reduce prey. The relative importance of these two processes on the litter invertebrate community in Hawaii is important, because they could affect the large number of endemic and endangered invertebrates. We determined the relative importance of litter resources, represented by leaf litter of two trees, an invasive nitrogen-fixer, Falcataria moluccana, and a native tree, Metrosideros polymorpha, and predation of an invasive terrestrial frog, Eleutherodactylus coqui, on …

What Has To Change For Forests To Be Saved? A Historical Example From The United States, Jedediah S. Purdy Jan 2009

What Has To Change For Forests To Be Saved? A Historical Example From The United States, Jedediah S. Purdy

Faculty Scholarship

This article looks at the conservation of American forests in the nineteenth and twentieth centuries to cast light on the prospects for global forest conservation in the twenty-first. At the beginning of the nineteenth century, Americans understood their forests as good only for cutting. By the end of the century a national scheme existed for comprehensive and permanent forest conservation. This new scheme became possible thanks to changes in scientific knowledge, the ideological self-image of the country, political institutions, and the imagination and moral commitments of citizens and social movements. A look at the changes that laid the foundations of …

Molecular Monitoring Of African Swine Fever Control Areas: Adult-Tick Targeted Re-Evaluation Of Mkuze Game Reserve, South Africa, L. F. Arnot, Johan T. Du Toit, A. D.S. Bastos

Wildland Resources Faculty Publications

The Mkuze Game Reserve (MGR), in north-eastern KwaZulu-Natal Province, South Africa is an African swine fever virus (ASF) controlled area. In a survey conducted in 1978, ASF prevalence in warthogs and Ornithodoros ticks in MGR was determined to be 2% and 0.06%, respectively. These values, acknowledged as being unusually low compared to other East and southern African ASF-positive sylvatic-cycle host populations, have not been assessed since. The availability of a sensitive PCR-based virus detection method, developed specifically for the sylvatic tampan host, prompted a re-evaluation of ASF virus (ASFV) prevalence in MGR ticks. Of the 98 warthog burrows inspected for …

Secularism, Religion, And Liberal Democracy In The United States, Kent Greenawalt Jan 2009

Secularism, Religion, And Liberal Democracy In The United States, Kent Greenawalt

Faculty Scholarship

This essay is divided into three categories: some brief remarks about forms of secularism, an outline of American constitutional law as it relates to religion, and a discussion from the standpoint of political philosophy of the proper place of religion (and other similar perspectives) in making political decisions within liberal democracies. Because the audience for whom the oral comments from which the essay is derived was mainly non-American, the middle part of the essay sets out many propositions familiar to anyone acquainted with this branch of constitutional law. And because of the informal nature of the original presentation, I offer …

Mitochondrial Fragmentation Is Involved In Methamphetamine-Induced Cell Death In Rat Hippocampal Neural Progenitor Cells., Changhai Tian, L. Charles Murrin, Jialin C. Zheng Jan 2009

Mitochondrial Fragmentation Is Involved In Methamphetamine-Induced Cell Death In Rat Hippocampal Neural Progenitor Cells., Changhai Tian, L. Charles Murrin, Jialin C. Zheng

Journal Articles: Pharmacology & Experimental Neuroscience

Methamphetamine (METH) induces neurodegeneration through damage and apoptosis of dopaminergic nerve terminals and striatal cells, presumably via cross-talk between the endoplasmic reticulum and mitochondria-dependent death cascades. However, the effects of METH on neural progenitor cells (NPC), an important reservoir for replacing neurons and glia during development and injury, remain elusive. Using a rat hippocampal NPC (rhNPC) culture, we characterized the METH-induced mitochondrial fragmentation, apoptosis, and its related signaling mechanism through immunocytochemistry, flow cytometry, and Western blotting. We observed that METH induced rhNPC mitochondrial fragmentation, apoptosis, and inhibited cell proliferation. The mitochondrial fission protein dynamin-related protein 1 (Drp1) and reactive oxygen …

Chrysler, Gm And The Future Of Chapter 11, Edward R. Morrison Jan 2009

Chrysler, Gm And The Future Of Chapter 11, Edward R. Morrison

Faculty Scholarship

Although they caused great controversy, the Chrysler and GM bankruptcies broke no new ground. They invoked procedures that are commonly observed in modern Chapter 11 reorganization cases. Government involvement did not distort the bankruptcy process; it instead exposed the reality that Chapter 11 offers secured creditors – especially those that supply financing during the bankruptcy case – control over the fate of distressed firms. Because the federal government supplied financing in the Chrysler and GM cases, it possessed the creditor control normally exercised by private lenders. The Treasury Department found itself with virtually the same, unchecked power that the FDIC …

A Phenomenological-Hermeneutic Analysis Of Experimental Infant Research, James L. Yu Jan 2009

A Phenomenological-Hermeneutic Analysis Of Experimental Infant Research, James L. Yu

Electronic Theses and Dissertations

This project challenges the dualistic conceptions in infant research literature by reexamining a collection of infant research records from a phenomenological, non-dualistic perspective. Grounded in the recent convergences between phenomenology and cognitive sciences, this project utilizes a combined phenomenological-hermeneutic method. This model of analysis is applied to three major areas in infant research: physical knowledge, memory-based learning, and social behaviors. The primary pool of data is drawn from written research records from both primary and secondary sources. To reinterpret empirical findings the analysis includes a systematic reexamination of the ontological presuppositions of infant researchers/scholars, and a reflective, experience-near approach. The …

Personal Sovereignty And Normative Power Skepticism, Jody S. Kraus Jan 2009

Personal Sovereignty And Normative Power Skepticism, Jody S. Kraus

Faculty Scholarship

In "The Correspondence of Contract and Promise," I claim that contract scholars have mistakenly presumed that they can assess the correspondence between contract and promise without first providing a theory of self-imposed moral responsibility that explains and justifies the promise principle. To illustrate the dependence of correspondence accounts of contract law on a theory of self-imposed moral responsibility, I demonstrate how a "personal sovereignty" account of individual autonomy explains how and why, contrary to existing correspondence theories, promissory responsibility corresponds to the rights and duties recognized by contract. Personal sovereignty recognizes the fundamental right of individuals not only to choose …

Agency And Luck, Joseph Raz Jan 2009

Agency And Luck, Joseph Raz

Faculty Scholarship

Advancing an account of responsibility which is based on the functioning of our rational capacities, the paper revisits some central aspects of the moral luck puzzle. It proposes a new variant of Williams’ agent-regret, but concludes that its scope does not coincide with cases of moral luck. It then distinguishes different ways in which the factors beyond our control feature in our engagement with the world which show how the guidance principle (we are responsible for actions guided by our rational powers) recognises a narrower range of situations of moral luck than is often supposed, allowing to distinguish between responsibility …

Street Stops And Broken Windows Revisited: The Demography And Logic Of Proactive Policing In A Safe And Changing City, Jeffrey Fagan, Amanda Geller, Garth Davies, Valerie West Jan 2009

Street Stops And Broken Windows Revisited: The Demography And Logic Of Proactive Policing In A Safe And Changing City, Jeffrey Fagan, Amanda Geller, Garth Davies, Valerie West

Faculty Scholarship

The contributions of order-maintenance policing and broken windows theory to New York City’s remarkable crime decline have been the subject of contentious debate. The dominant policing tactic in New York since the 1990s has been aggressive interdiction of citizens through street encounters in the search for weapons or drugs. Research showed that minority citizens in the 1990s were disproportionately stopped, frisked and searched at rates significantly higher than would be predicted by their race-specific crime rates, and that this excess enforcement was explained by the social structure of predominantly minority neighborhoods than by either their disorder or their crime rates. …

Post-Modern Meditations On Punishment: On The Limits Of Reason And The Virtues Of Randomization, Bernard E. Harcourt, Alon Harel, Ken Levy, Michael M. O'Hear, Alice Ristroph Jan 2009

Post-Modern Meditations On Punishment: On The Limits Of Reason And The Virtues Of Randomization, Bernard E. Harcourt, Alon Harel, Ken Levy, Michael M. O'Hear, Alice Ristroph

Faculty Scholarship

In this Criminal Law Conversation (Robinson, Ferzan & Garvey, eds., Oxford 2009), the authors debate whether there is a role for randomization in the penal sphere - in the criminal law, in policing, and in punishment theory. In his Tanner lectures back in 1987, Jon Elster had argued that there was no role for chance in the criminal law: “I do not think there are any arguments for incorporating lotteries in present-day criminal law,” Elster declared. Bernard Harcourt takes a very different position and embraces chance in the penal sphere, arguing that randomization is often the only way to avoid …

Contracts, Orphan Works, And Copyright Norms: What Role For Berne And Trips?, Jane C. Ginsburg Jan 2009

Contracts, Orphan Works, And Copyright Norms: What Role For Berne And Trips?, Jane C. Ginsburg

Faculty Scholarship

This Chapter addresses the extremes of private ordering, and the extent to which the principal multilateral copyright instruments, the Berne Convention and the TRIPs Accord, limit the range of State responses to the problems encountered at the far ends of the copyright-contract spectrum. At one end, we encounter private ordering at its most aggressive, in which private parties enter into agreements (or, more likely, the stronger party coerces the weaker parties, who may be mass market consumers) to protect subject matter or rights excluded from the ambit of copyright's exclusivity. At the other end, the difficulties arise not from overweening …

The Hidden Dichotomy In The Law Of Morality, Justin P. Nichols Jan 2009

The Hidden Dichotomy In The Law Of Morality, Justin P. Nichols

Campbell Law Review

This Comment will begin by exploring the dichotomy itself, and then carefully distinguishing civil and religious morality. The analysis will then examine Lawrence and clarify how the opinion affected the dichotomy. Next, this Comment will apply the post-Lawrence understanding of the rational basis test to several issues of concern raised by opponents of the decision. Finally, this Comment will speculate as to the possible implications of Lawrence for moral issues lying on the horizon.
