How The Leopard Hides Its Spots: Asip Mutations And Melanism In Wild Cats, Alexsandra Schneider, Victor A. David, Warren E. Johnson, Stephen J. O'Brien, Gregory S. Barsh, Marilyn Menotti-Raymond, Eduardo Eizirik

Biology Faculty Articles

The occurrence of melanism (darkening of the background coloration) is documented in 13 felid species, in some cases reaching high frequencies at the population level. Recent analyses have indicated that it arose multiple times in the Felidae, with three different species exhibiting unique mutations associated with this trait. The causative mutations in the remaining species have so far not been identified, precluding a broader assessment of the evolutionary dynamics of melanism in the Felidae. Among these, the leopard (Panthera pardus) is a particularly important target for research, given the iconic status of the ‘black panther’ and the extremely …

Effect Of Rising Temperature Due To Ozone Depletion On The Dynamics Of A Prey-Predator System: A Mathematical Model, O. P. Misra, Preety Kalra Dec 2012

Effect Of Rising Temperature Due To Ozone Depletion On The Dynamics Of A Prey-Predator System: A Mathematical Model, O. P. Misra, Preety Kalra

Applications and Applied Mathematics: An International Journal (AAM)

It is well recognized that the greenhouse gas such as Chlorofluoro Carbon (CFC) is responsible directly or indirectly for the increase in the average global temperature of the Earth. The presence of CFC is responsible for the depletion of ozone concentration in the atmosphere due to which the heat accompanied with the sun rays are less absorbed causing increase in the atmospheric temperature of the Earth. The increase in the temperature level directly or indirectly affects the dynamics of interacting species systems. Therefore, in this paper a mathematical model is proposed and analyzed using stability theory to asses the effects …

The Rna Binding Protein Ksrp Destabilizes Gap-43 Mrna To Limit Axonal Elongation In Cultured Hippocampal Neurons, Clark W. Bird Dec 2012

The Rna Binding Protein Ksrp Destabilizes Gap-43 Mrna To Limit Axonal Elongation In Cultured Hippocampal Neurons, Clark W. Bird

Biomedical Sciences ETDs

The KH-type splicing regulatory protein (KSRP) promotes the decay of AU-rich element (ARE) containing mRNAs. Although KSRP is expressed in the developing and mature nervous system, very little is known about its role in regulating gene expression in the brain. In this study, we utilized in vitro binding and decay studies to examine whether KSRP regulates the stability of the GAP-43 transcript, an ARE-containing neuronal mRNA whose protein product plays a role in axonal growth and synaptic plasticity. We found KSRP destabilizes GAP-43 mRNA by binding to the GAP-43 ARE, a process that depends on the presence of the fourth …

Altered Hemodynamics, Endothelial Function, And Protein Expression Occur With Aortic Coarctation And Persist After Repair, Arjun Menon, Thomas J. Eddinger, Hongfeng Wang, David C. Wendell, Jeffrey M. Toth, John F. Ladisa

Biomedical Engineering Faculty Research and Publications

Coarctation of the aorta (CoA) is associated with substantial morbidity despite treatment. Mechanically induced structural and functional vascular changes are implicated; however, their relationship with smooth muscle (SM) phenotypic expression is not fully understood. Using a clinically representative rabbit model of CoA and correction, we quantified mechanical alterations from a 20-mmHg blood pressure (BP) gradient in the thoracic aorta and related the expression of key SM contractile and focal adhesion proteins with remodeling, relaxation, and stiffness. Systolic and mean BP were elevated for CoA rabbits compared with controls leading to remodeling, stiffening, an altered force response, and endothelial dysfunction both …

Mi2Β Is Required For Γ-Globin Gene Silencing: Temporal Assembly Of A Gata-1-Fog-1-Mi2 Repressor Complex In Β-Yac Transgenic Mice, Flávia C. Costa, Halyna Fedosyuk, Allen M. Chazelle, Renee Y. Neades, Kenneth R. Peterson Dec 2012

Mi2Β Is Required For Γ-Globin Gene Silencing: Temporal Assembly Of A Gata-1-Fog-1-Mi2 Repressor Complex In Β-Yac Transgenic Mice, Flávia C. Costa, Halyna Fedosyuk, Allen M. Chazelle, Renee Y. Neades, Kenneth R. Peterson

Faculty and Staff Publications

Activation of γ-globin gene expression in adults is known to be therapeutic for sickle cell disease. Thus, it follows that the converse, alleviation of repression, would be equally effective, since the net result would be the same: an increase in fetal hemoglobin. A GATA-1-FOG-1-Mi2 repressor complex was recently demonstrated to be recruited to the -566 GATA motif of the Aγ-globin gene. We show that Mi2β is essential for γ-globin gene silencing using Mi2β conditional knockout β-YAC transgenic mice. In addition, increased expression of Aγ-globin was detected in adult blood from β-YAC transgenic mice containing a T>G HPFH point mutation …

Evaluation Of Soybean Hulls And Feed Additives In Finishing Beef Diets, Curtis J. Bittner Dec 2012

Evaluation Of Soybean Hulls And Feed Additives In Finishing Beef Diets, Curtis J. Bittner

Department of Animal Science: Dissertations, Theses, and Student Research

Replacing the amount of corn in finishing diets with ethanol byproducts, such as distillers grains, has been well researched and improves performance. However, research when including soybean hulls (SBH) in feedlot finishing diets with distillers grains is limited. Two feedlot experiments were conducted to evaluate the effects of SBH on animal performance and carcass characteristics in finishing diets. Dietary concentrations of SBH used were 0, 12.5, 25, and 37.5% of diet DM, in both experiments. Modified distillers grains plus solubles was included in the diet at 25% for Exp.1 while Exp. 2 contained an inclusion level of 40% wet distillers …

Grazing Cover Crops As An Alternative To Fallow And The Interaction Between Corn Processing Method And Condensed Distillers Solubles, Alex H. Titlow Dec 2012

Grazing Cover Crops As An Alternative To Fallow And The Interaction Between Corn Processing Method And Condensed Distillers Solubles, Alex H. Titlow

Department of Animal Science: Dissertations, Theses, and Student Research

Recently, producers in dryland wheat farming regions have made a shift from the typical winter wheat fallow rotation to a no-till system paired with cover crops. Cover crops have been shown to minimize these problems associated with the conventional fallow and possibly provide a source of forage. A 2-year grazing study was conducted to evaluate forage quality and utilization of cover crops (CC) planted to replace fallow in no-till wheat systems compared to crested wheatgrass pastures (CWP). Hand clipped and diet samples were greater in digestibility and CP for CC compared to CWP. The NDF and ADF content of the …

Structure-Function Analysis Of A Protein Encoded By The Bhv-1 Latency Related Gene, Devis Sinani Dec 2012

Structure-Function Analysis Of A Protein Encoded By The Bhv-1 Latency Related Gene, Devis Sinani

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Bovine herpes virus 1 (BHV-1) is a significant viral pathogen in cattle that induces a myriad of clinical symptoms. These symptoms include: conjunctivitis, upper respiratory tract infections, genital disorders, and abortions. BHV-1 infection can also lead to transient immune-suppression, which predisposes cattle to secondary bacterial infection leading to life-threatening pneumonia referred to as bovine respiratory disease (BRD). Following acute infection, BHV-1 establishes latency in sensory neurons within trigeminal ganglia. Reactivation of the virus can occur periodically, resulting in virus transmission. The latency-related (LR) RNA is the only abundantly expressed transcript in latently infected sensory neurons and it encodes several proteins, …

Evans's The Turducken And Chekhov's The Seagull, Brian R. Johnson Dec 2012

Evans's The Turducken And Chekhov's The Seagull, Brian R. Johnson

CLCWeb: Comparative Literature and Culture

In his article "Evans's The Turducken and Chekhov's The Seagull" Brian R. Johnson approaches The Turducken as a travesty of The Seagull, examining six iconic scenes from The Seagull, in order to explore the satirical effect of the altered scenes. In December of 2008, Bedlam Theatre of Minneapolis presented The Turducken, "a holiday dinner theater spectacular inspired by Anton Chekhov's The Seagull." Playwright Josef Evans takes Chekhov's 1895 work and turns the classic piece into a musical and farcical satire. The plot of The Turducken follows the plot of The Seagull, and some scenes …

Barthelme's "Paraguay," The Postmodern, And Neocolonialism, Daniel Chaskes Dec 2012

Barthelme's "Paraguay," The Postmodern, And Neocolonialism, Daniel Chaskes

CLCWeb: Comparative Literature and Culture

In his article "Barthelme's 'Paraguay,' the Postmodern, and Neocolonialism," Daniel Chaskes explores the analytic opportunities afforded by conjoining globalizing critical approaches with a story by an author who has often been circumscribed by the postmodern rubric. Donald Barthelme's "Paraguay," written the summer after Nelson Rockefeller's fact-finding mission to South America in 1969, provides a chance to consider modes of anti-colonial critique in Barthelme's work. It also offers examples of a more self-reflective criticism aimed at the U.S. counterculture and the indeterminacies of postmodernism. Chaskes reads "Paraguay" with the aim of understanding Barthelme's hemispheric interest and he investigates the multiple cultural …

Co-Space refers to interactive virtual environment modelled after the real world in terms of look-and-feel, functionalities and services. We have developed a 3D virtual world named Nan yang Technological University (NTU) Co-Space populated with virtual human characters. Three key requirements of realistic virtual humans in the virtual world have been identified, namely (1) autonomy: Agents can function on their own, (2) interactivity: Agents can interact naturally with players, and (3) personality: Agents can exhibit human traits and characteristics. Working towards these challenges, we propose a brain-inspired agent architecture that integrates goal-directed autonomy, natural language interaction and human-like personality. We conducted …

Maddy The Mathasaurus: An Interactive Math Game That Introduces The Concept And Properties Of Multiplication And Designed With Consideration For Children With Adhd, Mansi Vora

Theses

ADHD (Attention Deficit Hyperactivity Disorder) is one of the most commonly diagnosed behavioral disorder in kids, and is estimated to affect about 8-10% of school-aged children. Research shows that out of these children about 26% particularly have Math learning disabilities. The cognitive ability to understand and solve complex mathematical problems requires high level of concentration over a longer duration of time. This ability is disrupted in certain children due to ADHD. Therefore these students are likely to receive lower grades or even failure in standardized measures. However, if an educational environment is created that is specifically targeted towards reducing the …

Semi-Supervised Heterogeneous Evolutionary Co-Clustering, Pankaj Andhale Dec 2012

Semi-Supervised Heterogeneous Evolutionary Co-Clustering, Pankaj Andhale

Theses

One of the challenges of the machine learning problem is the absence of sufficient number of labeled instances or training instances. At the same time generating labeled data is expensive and time consuming. The semi-supervised approach has shown promising results to solve the problem of insufficient or fewer labeled instance datasets. The key challenge is incorporating the semi-supervised knowledge into the heterogeneous data which is evolving in nature. Most of the prior work that uses semi-supervised knowledge has been performed on heterogeneous static data. The semi-supervised knowledge is incorporated into data which aid the clustering algorithm to obtain better clusters. …

Evaluations of the local effects of global change are often confounded by the interactions of natural and anthropogenic factors that overshadow the effects of climate changes on ecosystems. Long-term watershed and natural elevation gradient studies at the Hubbard Brook Experimental Forest and in the surrounding region show surprising results demonstrating the effects of climate change on hydrologic variables (e.g., evapotranspiration, streamflow, soil moisture); the importance of changes in phenology on water, carbon, and nitrogen fluxes during critical seasonal transition periods; winter climate change effects on plant and animal community composition and ecosystem services; and the effects of anthropogenic disturbances and …
