Birkhoff Normal Forms And Kam Theory For Gumowski-Mira Equation, Mustafa Kulenovic, Zehra Nurkanović, Esmir Pilav

Mathematics Faculty Publications

By using the KAMtheory we investigate the stability of equilibrium solutions of the Gumowski-Mira equation: x_n+1 = (2ax_n)/(1 + x²_n) – x_n-1, n = 0, 1, …, where x_-1, x₀, ∈ (−∞,∞), and we obtain the Birkhoff normal forms for this equation for different equilibrium solutions.

A replication study of a previous genome-wide association study (GWAS) suggested that a SNP linked to the POLβ gene is associated with systemic lupus erythematosus (SLE). This SNP is correlated with decreased expression of Pol β, a key enzyme in the base excision repair (BER) pathway. To determine whether decreased Pol β activity results in SLE, we constructed a mouse model of POLβ that encodes an enzyme with slow DNA polymerase activity. We show that mice expressing this hypomorphic POLβ allele develop an autoimmune pathology that strongly resembles SLE. Of note, the mutant mice have shorter immunoglobulin heavy-chain junctions and …

Agricultural Conversion Without External Water And Nutrient Inputs Reduces Terrestrial Vegetation Productivity, William Kolby Smith, Cory C. Cleveland, Sasha C. Reed, Steven W. Running

Ecosystem and Conservation Sciences Faculty Publications

Driven by global population and standard of living increases, humanity co-opts a growing share of the planet's natural resources resulting in many well-known environmental trade-offs. In this study, we explored the impact of agriculture on a resource fundamental to life on Earth: terrestrial vegetation growth (net primary production; NPP). We demonstrate that agricultural conversion has reduced terrestrial NPP by ~7.0%. Increases in NPP due to agricultural conversion were observed only in areas receiving external inputs (i.e., irrigation and/or fertilization). NPP reductions were found for ~88% of agricultural lands, with the largest reductions observed in areas formerly occupied by tropical forests …

Developmental Link Between Sex And Nutrition; Doublesex Regulates Sex-Specific Mandible Growth Via Juvenile Hormone Signaling In Stag Beetles, Hiroki Gotoh, Hitoshi Miyakawa, Asano Ishikawa, Yuki Ishikawa, Yasuhiro Sugime, Douglas J. Emlen, Laura C. Lavine, Toru Miura

Biological Sciences Faculty Publications

Sexual dimorphisms in trait expression are widespread among animals and are especially pronounced in ornaments and weapons of sexual selection, which can attain exaggerated sizes. Expression of exaggerated traits is usually male-specific and nutrition sensitive. Consequently, the developmental mechanisms generating sexually dimorphic growth and nutritiondependent phenotypic plasticity are each likely to regulate the expression of extreme structures. Yet we know little about how either of these mechanisms work, much less how they might interact with each other. We investigated the developmental mechanisms of sex-specific mandible growth in the stag beetle Cyclommatus metallifer, focusing on doublesex gene function and its …

Homing Behavior Of The Limpet Species Collisella Scabra Living On The Limpet Species Lottia Gigantea, Lee F. Braithwaite

Journal of Undergraduate Research

Limpets are one-shelled marine mollusks that live on rocky beaches in the intertidal zone. The limpet species Collisella scabra is also found living on the shell of the limpet species L. gigantea. C. scabra exhibits an interesting phenomenon known as homing. This means that while not feeding, C. scabra are always found on the same spot on the rock or shell where they live. The C. scabra leave this spot, known as a home scar, to feed, but always return to it after they are done feeding. In this research, Chris Miller, Bryant Low, Christian Armstrong, and I examined the …

Aphid Amino Acid Transporter Regulates Glutamine Supply To Intracellular Bacterial Symbionts, Daniel R.G. Price, Honglin Feng, James D. Baker, Selvan Bavan, Charles W. Luetje, Alex C.C. Wilson

Faculty Publications

Endosymbiotic associations have played a major role in evolution. However, the molecular basis for the biochemical interdependence of these associations remains poorly understood. The aphid-Buchnera endosymbiosis provides a powerful system to elucidate how these symbioses are regulated. In aphids, the supply of essential amino acids depends on an ancient nutritional symbiotic association with the gamma-proteobacterium Buchnera aphidicola. Buchnera cells are densely packed in specialized aphid bacteriocyte cells. Here we confirm that five putative amino acid transporters are highly expressed and/or highly enriched in Acyrthosiphon pisum bacteriocyte tissues. When expressed in Xenopus laevis oocytes, two bacteriocyte amino acid transporters displayed significant …

The Rak/Frk Tyrosine Kinase Associates With And Internalizes The Epidermal Growth Factor Receptor, Ling Jin, Rolf J. Craven

Pharmacology and Nutritional Sciences Faculty Publications

Src is the founding member of a diverse family of intracellular tyrosine kinases, and Src has a key role in promoting cancer growth, in part, through its association with receptor tyrosine kinases. However, some Src-related proteins have widely divergent physiological roles, and these proteins include the Rak/Frk tyrosine kinase (Frk stands for Fyn-related kinase), which inhibits cancer cell growth and suppresses tumorigenesis. Rak/Frk phosphorylates and stabilizes the Pten tumor suppressor, protecting it from degradation, and Rak/Frk associates with the retinoblastoma (Rb) tumor suppressor. However, the role of Rak/Frk in receptor-mediated signaling is largely unknown. Here, we demonstrate that Rak/Frk associates …

Br[O/]Nsted Acid Catalyzed Asymmetric Allylation And Propargylation Of Aldehydes, Pankaj Jain

USF Tampa Graduate Theses and Dissertations

Carbonyl allylation and propargylation reactions have been an important tool for the stereocontrolled formation of carbon-carbon bonds for synthetic chemists. The chiral homoallylic and homopropargylic alcohols obtained from these reactions serve as versatile intermediates for the synthesis of natural and pharmaceutical products. Over the past three decades and continuing on, various synthetic groups around the globe have directed their research towards the efficient synthesis of these chiral moieties. In spite extensive research, asymmetric allylation and propargylation reactions remain an enduring challenge in organic chemistry.

Chapter 1 of this thesis describes the first phosphoric acid catalyzed asymmetric allylboration of aldehydes. We …

The Small Volume Autonomous Water Sampler (Svaws): An Innovative, Cost- Effective, Adaptable Protocol, Nicholas B. Fitzgerald

Dissertations and Theses

As of 2007, U.S. pesticide use stood at 1.1 billion pounds with 80% of all usage in agriculture. Such realities pose a potentially dangerous threat to our surface water bodies. This research provides a detailed analysis of the design, operation and field testing of a prototype water sampler, the Small Volume Autonomous Water Sampler (SVAWS). The research includes a discussion of the design and construction of the SVAWS. Seven USGS employees operated the SVAWS in a number of different states and conditions in order to collect samples for pesticide analysis. Field-testing outcomes of the SVAWS were measured through a Participant …

Peer Conversations About Inter-Racial And Inter-Ethnic Friendships, Lana Lee Buckholz

Dissertations and Theses

The purpose of this study was to understand how early adolescents talk about cross-racial and cross-ethnic friendships. Gordon Allport's intergroup contact theory provided the framework for studying the elements needed for inter-racial and inter-ethnic friendship formation. Qualitative data were drawn from four separately recorded peer group conversations. Participants (n=18) were recruited from Parrish Middle School in Salem, Oregon. Patterns that emerged from the data were sorted, categorized and identified according to the tenets of intergroup contact theory or extensions of intergroup contact theory. Analysis also looked at the use of metaphors and storytelling among adolescents. Results showed that while intergroup …

Quality-Space Theory In Olfaction, Benjamin D. Young, Andreas Keller, David Rosenthal

Publications and Research

Quality-space theory (QST) explains the nature of the mental qualities distinctive of perceptual states by appeal to their role in perceiving. QST is typically described in terms of the mental qualities that pertain to color. Here we apply QST to the olfactory modalities. Olfaction is in various respects more complex than vision, and so provides a useful test case for QST. To determine whether QST can deal with the challenges olfaction presents, we show how a quality space (QS) could be constructed relying on olfactory perceptible properties and the olfactory mental qualities then defined by appeal to that QS of …

Axl/Gas6/Nfκb Signalling In Schwannoma Pathological Proliferation, Adhesion And Survival., S. Ammoun, L. Provenzano, L. Zhou, M. Barczyk, K. Evans, D. A. Hilton, S. Hafizi, C. O. Hanemann

Peninsula Medical School

TAM family receptor tyrosine kinases comprising Tyro3 (Sky), Axl, and Mer are overexpressed in some cancers, correlate with multidrug resistance and contribute to tumourigenesis by regulating invasion, angiogenesis, cell survival and tumour growth. Mutations in the gene coding for a tumour suppressor merlin cause development of multiple tumours of the nervous system such as schwannomas, meningiomas and ependymomas occurring spontaneously or as part of a hereditary disease neurofibromatosis type 2. The benign character of merlin-deficient tumours makes them less responsive to chemotherapy. We previously showed that, amongst other growth factor receptors, TAM family receptors (Tyro3, Axl and Mer) are significantly …

Gendered Classrooms And Gendered Attire: Doing Gender On A College Campus, Jeff Lockhart Fcrh '13

The Fordham Undergraduate Research Journal

Gender and social identity rank as high priorities for undergraduate students, putting significant weight on their choice of apparel and accessories. In a university, students must also navigate the pressures of academic disciplines, which have their own norms of appearance and gender. Credibility in a discipline often hinges on one’s ability to conform to those disciplinary standards, but people whose social gender role does not match the gender of their discipline, such as womyn in the sciences or men in gender studies, will find these two forces at odds. This study leverages statistical observations of clothing and accessories to examine …

Sodium-Coupled Neutral Amino Acid Transporter 1 (Snat1) Modulates L-Citrulline Transport And Nitric Oxide (No) Signaling In Piglet Pulmonary Arterial Endothelial Cells, Anna Dikalova, Angela Fagiana, Judy L. Aschner, Michael Aschner, Marshall Summar, Candice D. Fike

Pediatrics Faculty Publications

Rationale

There is evidence that impairments in nitric oxide (NO) signaling contribute to chronic hypoxia-induced pulmonary hypertension. The L-arginine-NO precursor, L-citrulline, has been shown to ameliorate pulmonary hypertension. Sodium-coupled neutral amino acid transporters (SNATs) are involved in the transport of L-citrulline into pulmonary arterial endothelial cells (PAECs). The functional link between the SNATs, L-citrulline, and NO signaling has not yet been explored.

Objective

We tested the hypothesis that changes in SNAT1 expression and transport function regulate NO production by modulating eNOS coupling in newborn piglet PAECs.

Methods and Results

A silencing RNA (siRNA) technique was used to assess the contribution …
