Collateral Damage: The Endangered Center In American Politics, Samuel Issacharoff

Faculty Articles

Proves the assertion that the animating force behind the stunning electoral victory of California Governor Arnold Schwarzenegger in the election was the rebellion of the median voter, the center of American politics, against the perceived closing-off of the political process to competitive pressures. Troubling and complicated role of the plebiscite in a representative democracy; Assertion that the move toward plebicitary democracy is tied into the increased non-responsiveness of the political process; Role that constitutional law has played in furthering the decrease in competition in the political process and the consequence from this reduction in competitiveness.

Ethical Religion And The Struggle For Human Rights: The Case Of Martin Luther King, Jr., David A. J. Richards

Faculty Articles

My investigation here arises within a certain context, namely, my past work on political contractualism as the most plausible theory of American constitutional law and more recent interpretive work on the role that theory plays in explaining and understanding the impact on American constitutional law of various struggles for human rights (including not only the struggles of religious minorities, but movements for racial justice, as well as feminism and, most recently, the gay/lesbian movement). The appeal of contractualism, as a theory of American constitutional law, is the central place it accords basic human rights like conscience and speech and the …

Heritability Of Kinship Pheromone In The Beaver: How Is Information About Relatedness Coded?, Lixing Sun, Dietland Muller-Schwarze

Biology Faculty Scholarship

We attempted to estimate the narrow-sense heritability of single compounds and whole profile of the anal gland secretion (AGS) with the regression method using several sets of relatives in the beaver (Castor canadensis). We used GC (gas chromatography) and GC-MS (mass spectrometry) to characterize and quantify chemical compounds in beaver AGS. We found that the heritability of single compounds seemed to be low, whereas the heritability of AGS profile appeared to be moderate. We conclude that many compounds might be involved in the coding of genetic relatedness, which was through a combination of analog and digital coding using …

Is There A Right To Have Something To Say? One View Of The Public Domain, Diane L. Zimmerman

Faculty Articles

The debate over the role of the public domain in intellectual property law - its shape, its importance, its contents - is multi-faceted and complex, drawing on differing and often antithetical philosophical, economic and constitutional perspectives. This article attempts to take a new cut at understanding the public domain by asking whether or not, as a matter of constitutional law, there might be some kinds of speech goods that are simply off the table as subjects of intellectual property rights. That is to say, are there some kinds of communicative materials that, once in the public domain can not be …

Effect Of Wet And Dry Distillers Grains Plus Solubles And Supplemental Fat Level On Performance Of Yearling Finishing Cattle, Kyle J. Vander Pol, Galen E. Erickson, Terry J. Klopfenstein, Casey N. Macken

Nebraska Beef Cattle Reports

Two finishing trials were conducted to compare the addition of fat from either wet or dry distillers byproducts (WDGS; DDGS) to that provided from one of two commercially available fat sources (corn oil, Trial 1; tallow, Trial 2). In Trial 1, feed conversion and ADG decreased linearly as level of corn oil increased, while feed conversion and ADG were improved numerically as the level of WDGS increased in the diet. In Trial 2, no differences in performance were observed comparing cattle fed dry distillers grains plus solubles to cattle fed diets containing tallow. WDGS provided 12 and 17% more net …

The C-Type Lectin Sign-R1 Mediates Uptake Of The Capsular Polysaccharide Of Streptococcus Pneumoniae In The Marginal Zone Of Mouse Spleen, Youngsun Kang, Jae Y. Kim, Sandra A. Bruening

Publications

SIGN-R1, a recently discovered C-type lectin expressed at high levels on macrophages within the marginal zone of the spleen, mediates the uptake of dextran polysaccharides by these phagocytes. We now find that encapsulated Streptococcus pneumoniae are rapidly cleared by these macrophages from the bloodstream, and that capture also takes place when different cell lines express SIGN-R1 after transfection. To assess the role of the capsular polysaccharide of S. pneumoniae(CPS) in the interaction of SIGN-R1 with pneumococci, we first studied binding and uptake of serotype 14 CPS in transfected cells. Binding was observed and was of a much higher avidity (3,000-fold) …

Using Microscopy To Examine Mechanisms Of Cell Division, Lily Copenagle

Student Theses and Dissertations

The accurate segregation of chromosomes during cell division requires the assembly of a microtubule-based mitotic spindle. In the research presented here, I examined two aspects of mitotic spindle morphogenesis. First, I looked at how chromosomes attach to microtubules in mitosis. The capture of microtubule plus-ends by kinetochores (the site of chromosome-microtubule attachment) has been described previously. However, recent data suggests that another mechanism must also contribute to this essential process. Here, with the aid of real-time confocal microscopy, I present direct evidence for an additional chromosome-spindle attachment mechanism in which the minus-ends of microtubules attached to chromosomes are captured by …

Attenuated Salmonella Typhimurium Can Be Used To Transduce Human Dendritic Cells Towards Vaccination Against Hiv-1, Deborah Gurner

Student Theses and Dissertations

The promise of DNA vaccination is limited in part by invasive, untargeted administration. We refined the strategy by incorporating attenuated bacteria to deliver plasmids directly to APCs. Initial studies involved human macrophages, which were infected with aroASalmonella typhimurium transformed with eukaryotic vectors encoding 8-galactosidase. Results of staining with x-gal demonstrated effective transfer of plasmids to the target cells, which expressed the reporter gene themselves. Similarly, immunocytochemical staining of macrophages infected with bacteria bearing a eukaryotic vector encoding HIV-1 env showed expression of the viral gene. Macrophages were also infected with bacteria harboring vectors encoding SIV env and HIV-1 tat, then …

Roles For The E3 Ligase Itch In Immune Response Modulation, Sukhvinder Kaur Sahota

Student Theses and Dissertations

Cloning of the inversion breakpoints in the agouti mutant strain a has implicated the E3 ligase Itch in the spontaneous inflammation that occurs in these mice. 1 RH Anaylsis of a mice suggests that the inflammatory disease is due to a dysregulated T helper type-2 immune response. In order to verify the importance of Itch inactivation in the spontaneous inflammation of a mice and to determine which cell type is responsible for the pathology, the Itch gene has been targeted for conditional deletion in mice using the Cre-loxP system. The results presented in this thesis provide the first direct evidence …

Differential Screening In Immunodeficient Mice Reveals Bacterial Enzymes With Unexpected Roles In Host-Pathogen Interactions, Katherine B. Hisert

Student Theses and Dissertations

Over centuries of co-existence with their hosts, microbes that are exclusively vertebrate pathogens have evolved mechanisms for manipulation of host cells and evasion of the immune system. Some pathogens dodge the immune response by altering the functions of and hiding within the very cells that should be consuming and digesting them: macrophages. The aim of these studies was to explore the dynamic interactions the host with two microbes that opt to live within the macrophage phagosome: Mycobacterium tuberculosis (Mtb) and Salmonella typhimurium. In order to identify bacterial genes that provide protection against specific host immune pathways, we have developed the …

Site And Mechanism Of Leptin's Antisteatotic And Insulin Sensitizing Actions In Lipodystrophic Liver, Esra Asilmaz

Student Theses and Dissertations

An adipocyte hormone which functions as the afferent signal in a negative feedback loop regulating energy balance, has profound effects on glucose and lipid metabolisms. Lipodystrophic humans and mice have a complete or partial absence of adipose tissue and a secondary reduction of leptin. This is associated with insulin resistance and hepatic steatosis, which are corrected by leptin administration. This thesis aimed to define the site of leptin action and understand the molecular basis of leptin's insulin sensitizing and antisteatotic effects in lipodystrophy. To determine the site of leptin action, we treated lipodystrophic aP2-nSREBP-1c mice with a low dose of …

A Novel Subfamily Of Three Star-Related Lipid Transfer Proteins That Are Differentially-Regulated And Function In Intracellular Cholesterol Metabolism, Raymond E. Soccio

Student Theses and Dissertations

This thesis describes the discovery, cloning, and initial characterization of StarD4, sterol-regulated gene encoding a StAR-related lipid transfer (START) protein, and its close homologues, StarD5 and StarD6. StarD4 was identified using cDNA microarrays, as liver StarD4 expression decreased three-fold in mice fed a high cholesterol diet. StarD4 also sterol-regulated in cultured cells, and a functional sterol regulatory element (SRE) identified in its promoter. StarD4 was preferentially activated in mouse liver by SREBP-rather than SREBP-1, supporting a role in cholesterol rather than fatty acid metabolism. X-ray crystal structure of StarD4 was solved, revealing a hydrophobic lipid binding cavity described for other …

Life Without Gpr7, The Neuropeptide W1 Receptor: Regulation Of Energy Homeostasis By Gpr7 And Its Endogenous Neuropeptide Ligands, Makoto Ishii

Student Theses and Dissertations

Classic lesion experiments from the 1940s have established the hypothalamus as playing an essential role in controlling energy homeostasis. Gold-thioglucose (GTG) induces lesions in the ventromedial nucleus of the hypothalamus (VMH) resulting in hyperphagia and obesity. To identify genes involved in the hypothalamic regulation of energy homeostasis, we employed a screen to search for genes that were dysregulated in GTG induced obese mice. In this screen, GPR7, the endogenous G protein-coupled receptor (GPCR) for the recently identified ligands neuropeptide B (NPB) and neuropeptide W (NPW), was found to be specifically down-regulated after GTG treatment. The physiological role of GPR7 was …

Molecular Basis Of Vertebrate Embryonic Migration, Paris A. Skourides

Student Theses and Dissertations

Embryology aims at understanding how a single fertilized cell develops into a complex multicellular organism. Initially the embryo is no more than a ball of cells where the three primordial layers, the ectoderm, mesoderm and the endoderm are one on top of the other. The three germ layers will go on to form all the tissues and organs of the embryo. For example, the ectoderm will give rise to epidermis and the nervous system; the mesoderm to muscles, the skeletal system, the dermis or inner layer of the skin, the circulatory, excretory, and reproductive systems; and, finally, the endoderm will …
