A Plant Virus Evolved By Acquiring Multiple Nonconserved Genes To Extend Its Host Range, Satyanarayana Tatineni, Cecile J. Robertson, Stephen M. Garnsey, William O. Dawson Oct 2011

A Plant Virus Evolved By Acquiring Multiple Nonconserved Genes To Extend Its Host Range, Satyanarayana Tatineni, Cecile J. Robertson, Stephen M. Garnsey, William O. Dawson

Department of Plant Pathology: Faculty Publications

Viruses have evolved as combinations of genes whose products interact with cellular components to produce progeny virus throughout the plants. Some viral genes, particularly those that are involved in replication and assembly, tend to be relatively conserved, whereas other genes that have evolved for interactions with the specific host for movement and to counter host–defense systems tend to be less conserved. Closteroviridae encode 1–5 nonconserved ORFs. Citrus tristeza virus (CTV), a Closterovirus, possesses nonconserved p33, p18, and p13 genes that are expendable for systemic infection of the two laboratory hosts, Citrus macrophylla and Mexican lime. In this study, we …

Reconceiving Surrogacy: Toward A Reproductive Justice Account Of Indian Surrogacy, Alison Bailey Oct 2011

Reconceiving Surrogacy: Toward A Reproductive Justice Account Of Indian Surrogacy, Alison Bailey

Faculty Publications - Philosophy

My project here is to argue for a reproductive justice approach to Indian surrogacy. I begin by crafting the best picture of Indian surrogacy available to me while marking some worries about the role of discursive colonialism and epistemic honesty in this project. Western feminists’ responses to contract pregnancy fall loosely into two moments: Post-Baby M approaches that raised questions about the morality of surrogacy and the new reproductive technologies, and more recent feminist ethnographic engagements that aim to capture how these practices are lived, embodied, and negotiated. Both approaches have shortcomings. Extending Western moral frameworks (e.g. liberal feminist approaches) …

The Rice Miniature Inverted Repeat Transposable Element Mping Is An Effective Insertional Mutagen In Soybean, C. Nathan Hancock, Feng Zhang, Kristen Floyd, Aaron O. Richardson, Peter Lafayette, Donna Tucker, Susan R. Wessler, Wayne A. Parrott Oct 2011

The Rice Miniature Inverted Repeat Transposable Element Mping Is An Effective Insertional Mutagen In Soybean, C. Nathan Hancock, Feng Zhang, Kristen Floyd, Aaron O. Richardson, Peter Lafayette, Donna Tucker, Susan R. Wessler, Wayne A. Parrott

Faculty Publications

Insertional mutagenesis of legume genomes such as soybean (Glycine max) should aid in identifying genes responsible for key traits such as nitrogen fixation and seed quality. The relatively low throughput of soybean transformation necessitates the use of a transposon-tagging strategy where a single transformation event will produce many mutations over a number of generations. However, existing transposon-tagging tools being used in legumes are of limited utility because of restricted transposition (Ac/Ds: soybean) or the requirement for tissue culture activation (Tnt1: Medicago truncatula). A recently discovered transposable element from rice (Oryza …

Specific Sequence Determinants Of Mir-15/107 Microrna Gene Group Targets, Peter T. Nelson, Wang-Xia Wang, Guogen Mao, Bernard R. Wilfred, Kevin Xie, Mary H. Jennings, Zhen Gao, Xiaowei Wang Oct 2011

Specific Sequence Determinants Of Mir-15/107 Microrna Gene Group Targets, Peter T. Nelson, Wang-Xia Wang, Guogen Mao, Bernard R. Wilfred, Kevin Xie, Mary H. Jennings, Zhen Gao, Xiaowei Wang

Pathology and Laboratory Medicine Faculty Publications

MicroRNAs (miRNAs) target mRNAs in human cells via complex mechanisms that are still incompletely understood. Using anti-Argonaute (anti-AGO) antibody co-immunoprecipitation, followed by microarray analyses and downstream bioinformatics, 'RIP-Chip' experiments enable direct analyses of miRNA targets. RIP-Chip studies (and parallel assessments of total input mRNA) were performed in cultured H4 cells after transfection with miRNAs corresponding to the miR-15/107 gene group (miR-103, miR-107, miR-16 and miR-195), and five control miRNAs. Three biological replicates were run for each condition with a total of 54 separate human Affymetrix Human Gene 1.0 ST array replicates. Computational analyses queried for determinants of miRNA:mRNA binding. The …

Layer-By-Layer Fabrication Of Covalently Crosslinked And Reactive Polymer Multilayers Using Azlactone-Functionalized Copolymers: A Platform For The Design Of Functional Biointerfaces, Maren E. Buck, David M. Lynn Oct 2011

Layer-By-Layer Fabrication Of Covalently Crosslinked And Reactive Polymer Multilayers Using Azlactone-Functionalized Copolymers: A Platform For The Design Of Functional Biointerfaces, Maren E. Buck, David M. Lynn

Chemistry: Faculty Publications

We report a method for modulating the physicochemical properties of surfaces that is based on the reactive layer-by-layer fabrication of covalently crosslinked thin films using azlactone-functionalized copolymers. We demonstrate that copolymers containing different molar ratios of methyl methacrylate (MMA) and 2-vinyl-4,4-dimethylazlactone (VDMA) can be alternately deposited with poly(ethyleneimine) to assemble covalently crosslinked thin films. Characterization using ellipsometry demonstrates that, in general, film growth and thickness decrease as the content of reactive, azlactone functionality in the copolymer used to assemble the film decreases. Reflective infrared spectroscopy experiments demonstrate that films fabricated from MMA:VDMA copolymers contain residual azlactone functionality and that these …

Dietary-Resistant Starch Improves Maternal Glycemic Control In Goto-Kakizaki Rat, Li Shen, Michael J. Keenan, Anne Raggio, Cathy Williams, Roy J. Martin Oct 2011

Dietary-Resistant Starch Improves Maternal Glycemic Control In Goto-Kakizaki Rat, Li Shen, Michael J. Keenan, Anne Raggio, Cathy Williams, Roy J. Martin

Faculty Publications

Scope: Dietary prebiotics show potential in anti-diabetes. Dietary resistant starch (RS) has a favorable impact on gut hormone profiles, including glucagon-like peptide-1 (GLP-1) consistently released, a potent anti-diabetic incretin. Also RS reduced body fat and improved glucose tolerance in rats and mice. In the current project, we hypothesize that dietary-resistant starch can improve insulin sensitivity and pancreatic β cell mass in a type 2 diabetic rat model. Altered gut fermentation and microbiota are the initial mechanisms, and enhancement in serum GLP-1 is the secondary mechanism. Methods and results: In this study, GK rats were fed an RS diet with 30% …

In Search Of The Neurobiological Substrates For Social Playfulness In Mammalian Brains, Stephen M. Siviy, Jaak Panksepp Oct 2011

In Search Of The Neurobiological Substrates For Social Playfulness In Mammalian Brains, Stephen M. Siviy, Jaak Panksepp

Psychology Faculty Publications

Play behavior is a fundamental and intrinsic neurobehavioral process in the mammalian brain. Using rough-and-tumble play in the juvenile rat as a model system to study mammalian playfulness, some of the relevant neurobiological substrates for this behavior have been identified, and in this review this progress. A primary-process executive circuit for play in the rat that includes thalamic intralaminar nuclei, frontal cortex and striatum can be gleaned from these data. Other neural areas that may interact with this putative circuit include amygdala, ventral hypothalamus, periaqueductal gray (PAG), and deep tectum, as well as ascending dopamine systems which participate in all …

Serotonin, Motivation, And Playfulness In The Juvenile Rat, Stephen M. Siviy, Loren M. Deron, Chelsea R. Kasten Oct 2011

Serotonin, Motivation, And Playfulness In The Juvenile Rat, Stephen M. Siviy, Loren M. Deron, Chelsea R. Kasten

Psychology Faculty Publications

The effects of the selective 5HT1A agonist 8-OH-DPAT were assessed on the play behavior of juvenile rats. When both rats of the test pair were comparably motivated to play, the only significant effect of 8-OH-DPAT was for play to be reduced at higher doses. When there was a baseline asymmetry in playful solicitation due to a differential motivation to play and only one rat of the pair was treated, low doses of 8-OH-DPAT resulted in a collapse of asymmetry in playful solicitations. It did not matter whether the rat that was treated initially accounted for more nape contacts or fewer …

Integrating Ecosystem Services, River Restoration And Community: A Case Study At Fisher's Bend, Michael Carlson Oct 2011

Integrating Ecosystem Services, River Restoration And Community: A Case Study At Fisher's Bend, Michael Carlson

Environmental Science and Management Professional Master's Project Reports

Natural areas and ecosystem services at the edge of urban areas are threatened by increasing development. This paper examines how community based restoration partnerships can work to identify, protect and restore ecosystem services provided by salmon and our local rivers. Floodplains provide a wide range of ecosystem services to urban and rural communities and we should work collaboratively to protect and restore them. Floodplains are especially valuable and important for salmon recovery. By using a case study, we explore the process and feasibility of restoring off-channel salmon habitat at Fisher's Bend in the lower Clackamas river. A feasibility study was …

Meritocracy Voting: Measuring The Unmeasurable, Peter C.B. Phillips Oct 2011

Meritocracy Voting: Measuring The Unmeasurable, Peter C.B. Phillips

Cowles Foundation Discussion Papers

Learned societies commonly carry out selection processes to add new fellows to an existing fellowship. Criteria vary across societies but are typically based on subjective judgments concerning the merit of individuals who are nominated for fellowships. These subjective assessments may be made by existing fellows as they vote in elections to determine the new fellows or they may be decided by a selection committee of fellows and officers of the society who determine merit after reviewing nominations and written assessments. Human judgment inevitably plays a central role in these determinations and, notwithstanding its limitations, is usually regarded as being a …

Structure Of Parasite Component Communities Of Didelphid Marsupials: Insights From A Comparative Study, F Agustín Jiménez, François Catzeflis, Scott L Gardner Oct 2011

Structure Of Parasite Component Communities Of Didelphid Marsupials: Insights From A Comparative Study, F Agustín Jiménez, François Catzeflis, Scott L Gardner

Publications

The parasite fauna of the gray four-eyed opossum, Philander opossum (Linnaeus, 1758), and the common opossum, Didelphis marsupialis Linnaeus, 1758, in Camp du Tigre, French Guiana, is characterized. Nine species from the gastrointestinal system were recovered from both species, which shared 80% of their parasites. The parasite fauna comprised several monoxenous species (63%) and was dominated by Aspidodera raillieti Travassos, 1914, which exhibited high levels of prevalence and abundance in both communities. Only 2 species (Moennigia sp. and Spirura guianensis) had been recorded in other species of mammals. Both species richness and taxonomic composition at the level of …

Polymorphic Structures Of Alzheimer's Beta-Amyloid Globulomers, Jie Zheng Oct 2011

Polymorphic Structures Of Alzheimer's Beta-Amyloid Globulomers, Jie Zheng

Chemical, Biomolecular, and Corrosion Engineering Faculty Research

Misfolding and self-assembly of Amyloid-β (Aβ) peptides into amyloid fibrils is pathologically linked to the development of Alzheimer's disease. Polymorphic Aβ structures derived from monomers to intermediate oligomers, protofilaments, and mature fibrils have been often observed in solution. Some aggregates are on-pathway species to amyloid fibrils, while the others are off-pathway species that do not evolve into amyloid fibrils. Both on-pathway and off-pathway species could be biologically relevant species. But, the lack of atomic-level structural information for these Aβ species leads to the difficulty in the understanding of their biological roles in amyloid toxicity and amyloid formation.

Effects Of Experimental Nitrogen Additions On Plant Diversity In Tropical Forests Of Contrasting Disturbance Regimes In Southern China, Xiankai Lu, Jiangming Mo, Frank S. Gilliam, Guirui Yu, Wei Zhang, Yunting Fang, Juan Huang Oct 2011

Effects Of Experimental Nitrogen Additions On Plant Diversity In Tropical Forests Of Contrasting Disturbance Regimes In Southern China, Xiankai Lu, Jiangming Mo, Frank S. Gilliam, Guirui Yu, Wei Zhang, Yunting Fang, Juan Huang

Biological Sciences Faculty Research

Responses of understory plant diversity to nitrogen (N) additions were investigated in reforested forests of contrasting disturbance regimes in southern China from 2003 to 2008: disturbed forest (withharvesting of understory vegetation and litter) and rehabilitated forest (without harvesting). Experimental additions of N were administered as the following treatments: Control, 50 kg N ha1yr1, and 100kg N ha1yr1. Nitrogen additions did not significantly affect understory plant richness, density,and cover in the disturbed forest. Similarly, no significant response was found for canopy closure in thisforest. In the rehabilitated forest, species richness and density showed no significant response to Nadditions; however, understory cover …

Adult height is a classic polygenic trait of high heritability (h 2 ~0.8). More than 180 single nucleotide polymorphisms (SNPs), identified mostly in populations of European descent, are associated with height. These variants convey modest effects and explain ~10% of the variance in height. Discovery efforts in other populations, while limited, have revealed loci for height not previously implicated in individuals of European ancestry. Here, we performed a meta-analysis of genome-wide association (GWA) results for adult height in 20,427 individuals of African ancestry with replication in up to 16,436 African Americans. We found two novel height loci (Xp22-rs12393627, P = …
