Influence Of Urban Disturbances, Soil Properties, And Other Abiotic And Biotic Factors On L. Maackii Invasions Of Remnant Urban Riparian Hardwood Forests, Taylor B. Johnson

Environmental Studies: Student Scholarship & Creative Works

Urbanization is a global demographic trend that may have significant and detrimental effects on adjacent urban ecosystems. Lonicer Maackii (L. maackii), commonly referred to as Amur honeysuckle, is an invasive shrub that has invaded the remnant temperate hardwood forests of Rock Island County, IL. The goal of this study was to examine the effects of urbanization and urban soil properties on the degree of L. maackii invasion throughout this county next to the Mississippi river. Soil samples were tested at 36 forest sites for Soil Organic Matter and Soil texture. Linear regression models were ran on the results of …

Glutamate, Ornithine, Arginine, Proline, And Polyamine Metabolic Interactions: The Pathway Is Regulated At The Post-Transcriptional Level, Rajtilak Majumdar, Boubker Barchi, Swathi A. Turlapati, Maegan Gagne, Rakesh Minocha, Stephanie Long, Subhash C. Minocha

New Hampshire Agricultural Experiment Station Publications

The metabolism of glutamate into ornithine, arginine, proline, and polyamines is a major network of nitrogen-metabolizing pathways in plants, which also produces intermediates like nitric oxide, and γ-aminobutyric acid (GABA) that play critical roles in plant development and stress. While the accumulations of intermediates and the products of this network depend primarily on nitrogen assimilation, the overall regulation of the interacting sub-pathways is not well understood. We tested the hypothesis that diversion of ornithine into polyamine biosynthesis (by transgenic approach) not only plays a role in regulating its own biosynthesis from glutamate but also affects arginine and proline biosynthesis. Using …

Method For Measuring The Unbinding Energy Of Strongly-Bound Membrane-Associated Proteins, Elisa La Bauve, Briana C. Vernon, Dongmei Ye, David M. Rogers, Cathryn M. Siegrist, Bryan D. Carson, Susan B. Rempe, Aihua Zheng, Margaret Kielian, Andrew P. Shreve, Michael S. Kent

Chemistry Faculty Publications

We describe a new method to measure the activation energy for unbinding (enthalpy ΔH*_u and free energy ΔG*_u) of a strongly-bound membrane-associated protein from a lipid membrane. It is based on measuring the rate of release of a liposome-bound protein during centrifugation on a sucrose gradient as a function of time and temperature. The method is used to determine ΔH*_u and ΔG*_u for the soluble dengue virus envelope protein (sE) strongly bound to 80:20 POPC:POPG liposomes at pH 5.5. ΔH*_u is determined from the Arrhenius equation whereas ΔG*_u is …

Impaired Mitochondrial Function Due To Familial Alzheimers Disease-Causing Presenilins Mutants Via Calcium Disruptions, Patrick T. Toglia, King-Ho Cheung, Don-On Daniel Mak, Ghamim Ullah

Physics Faculty Publications

Muatans in presenilins (PS1 or PS2) is the major cause of Familial Alzheimer's disease (FAD). FAD causing PS mutants affect intracellular Ca²⁺ ([Ca²⁺]_i) homeostasis by enhancing the gating of inositol trisphosphate (IP₃) receptor (IP₃R) Ca²⁺ release channels on the endoplasmic reticulum (ER), leading to exaggerated Ca²⁺ release into the cytoplasm (Cheung et al., Neuron 2008:871, Sci. Signal 2010:ra22). Using experimental IP₃R-mediated Ca²⁺ release data, in conjunction with a computational model of cell bioenergetics (Cortassa et al., Biophys. J. 2003:2734, 2004:2067), we explore how the differences in …

The Effects Of Family Structure Stability And Transitions On Young Children’S Sleep: Evidence From The Millennium Cohort Study, Shanea Foster, Mikaela Dufur

Journal of Undergraduate Research

Over the years, family structure has become a topic of great interest in the social science community, particularly as it pertains to family structure type (i.e. biological parents, cohabiting, stepparents, etc.) (Dufur et al., 2010). More recently, family stability has come under scrutiny. Family structure has the potential to change over time, whether it be experiencing a disruption (going from married parents to single) or reconstitution (going from single parent to married or having a partner). We find interest in family structure changes over time as it pertains to its potential effects on their children’s sleeping behavior (Wong, Brower & …

Involvement Of Parp1 In The Regulation Of Alternative Splicing, Elena Matveeva, John Maiorano, Qingyang Zhang, Abdallah M. Eteleeb, Paolo Convertini, Jing Chen, Vittoria Infantino, Stefan Stamm, Jiping Wang, Eric C. Rouchka, Yvonne N. Fondufe-Mittendorf

Molecular and Cellular Biochemistry Faculty Publications

Specialized chromatin structures such as nucleosomes with specific histone modifications decorate exons in eukaryotic genomes, suggesting a functional connection between chromatin organization and the regulation of pre-mRNA splicing. Through profiling the functional location of Poly (ADP) ribose polymerase, we observed that it is associated with the nucleosomes at exon/intron boundaries of specific genes, suggestive of a role for this enzyme in alternative splicing. Poly (ADP) ribose polymerase has previously been implicated in the PARylation of splicing factors as well as regulation of the histone modification H3K4me3, a mark critical for co-transcriptional splicing. In light of these studies, we hypothesized that …

Modulating Foveal Representation Can Influence Visual Discrimination In The Periphery, Qing Yu, Won Mok Shim

Dartmouth Scholarship

A previous study by Williams et al. (2008) provided evidence for a novel form of feedback in the visual system, whereby peripheral information is contained in foveal retinotopic cortex. Beyond its possible implication for peripheral object recognition, few studies have examined the effect of a direct behavioral manipulation of the foveal feedback representation. To address this question, we measured participants' peripheral visual discrimination performance while modulating their foveal representation in a series of psychophysical experiments. On each trial, participants discriminated the identities of briefly presented novel, three-dimensional objects or the orientations of gratings in a peripheral location while fixating at …

In Crystallo Capture Of A Covalent Intermediate In The Udp-Galactopyranose Mutase Reaction, Ritcha Mehra-Chaudhary, Yumin Dai, Pablo Sobrado, John J. Tanner

Chemistry Faculty Research & Creative Works

UDP-galactopyranose mutase (UGM) plays an essential role in galactofuranose biosynthesis in pathogens by catalyzing the conversion of UDP-galactopyranose to UDP-galactofuranose. Here we report the first crystal structure of a covalent intermediate in the UGM reaction. The 2.3 Å resolution structure reveals UDP bound in the active site and galactopyranose linked to the FAD through a covalent bond between the anomeric C of galactopyranose and N5 of the FAD. The structure confirms the role of the flavin as nucleophile and supports the hypothesis that the proton destined for O5 of galactofuranose is shuttled from N5 of the FAD via O4 of …

Design Of Barrier Coatings On Kink-Resistant Peripheral Nerve Conduits., Basak Acan Clements, Jared Bushman, N. Sanjeeva Murthy, Mindy Ezra, Christopher M. Pastore, Joachim Kohn

Kanbar College Faculty Papers

Here, we report on the design of braided peripheral nerve conduits with barrier coatings. Braiding of extruded polymer fibers generates nerve conduits with excellent mechanical properties, high flexibility, and significant kink-resistance. However, braiding also results in variable levels of porosity in the conduit wall, which can lead to the infiltration of fibrous tissue into the interior of the conduit. This problem can be controlled by the application of secondary barrier coatings. Using a critical size defect in a rat sciatic nerve model, the importance of controlling the porosity of the nerve conduit walls was explored. Braided conduits without barrier coatings …

The Impact Of Length Of Stay On Adjudicated Male Youths;' Language Use: Focusing On Linguistic Analysis Of Verbal Samples, Yousun Shin Ph.D., Terry P. Overton Ph.D., Ed.D., Zelica Espinoza M.Ed.

Journal of Human Services: Training, Research, and Practice

The primary purpose of the study was to examine the impact of the length of juvenile offenders’ stay in a residential facility on attitudinal changes, measured by language use of 22 participants’ interviews analyzed by using a computerized text tool called Linguistic Inquiry and Word Count (LIWC) to obtain a measure of language use. A series of one-way ANOVA (SPSS 18.0 version) were used to examine the differences between the groups identified by the length of stay and interview interval. The results indicate that the length of stay significantly impacts language use regarding the language categories of affective process words …

Conjugate Haemophilus Influenzae Type B Vaccines For Sickle Cell Disease., Slimane Allali, Martin Chalumeau, Odile Launay, Samir K. Ballas, Mariane De Montalembert

Cardeza Foundation for Hematologic Research

BACKGROUND: People affected with sickle cell disease are at high risk of infection from Haemophilus influenzae type b. Before the implementation of Haemophilus influenzae type b conjugate vaccination in high-income countries, this was responsible for a high mortality rate in children under five years of age. In African countries, where coverage of this vaccination is still extremely low, Haemophilus influenzae type b remains one of the most common cause of bacteraemias in children with sickle cell disease. The increased uptake of this conjugate vaccination may substantially improve the survival of children with sickle cell disease.

OBJECTIVES: The primary objective was …

Determination Of The Goos-Hänchen Shift In Dielectric Waveguides Via Photo Emission Electron Microscopy In The Visible Spectrum, Theodore Stedmark, Robert Campbell Word, Rolf Kӧnenkamp

Physics Faculty Publications and Presentations

Photoemission Electron Microscopy (PEEM) is a versatile tool that relies on the photoelectric effect to produce high-resolution images. Pulse lasers allow for multi-photon PEEM where multiple photons are required excite a single electron. This non-linear process can directly image the near field region of electromagnetic fields in materials. We use this ability here to analyze wave propagation in a linear dielectric waveguide with wavelengths of 410nm and 780nm. The propagation constant of the waveguide can be extracted from the interference pattern created by the coupled and incident light and shows distinct polarization dependence. The electromagnetic field interaction at the boundaries …

Direct Measurement Of Hairpin‐Like Vortices In The Bottom Boundary Layer Of The Coastal Ocean, Edward C.C. Steele, W. Alex M. Nimmo‐Smith, Andrey Vlasenko

School of Biological and Marine Sciences

Laboratory measurements and numerical modeling at low Reynolds numbers (Re_θ<7700) indicate the energy-containing turbulence of boundary layer flows comprises coherent packets of hairpin vortices. Here direct measurements in the bottom boundary layer of the coastal ocean at higher Reynolds numbers (Re_θ = 266,150) show tidal flows also contain packets of large vortices separated by periods of more quiescent conditions. The 1452 vortices recorded within a 20 min period are typically aligned along stream (∼8.0° from the mean flow direction) and inclined to the horizontal (∼27.0° from the seabed), with a mean period of occurrence of 4.3 s. These results lend three-dimensional, in situ support to an interpretation of the coastal ocean bottom boundary layer as comprising coherent packets of hairpin vortices. This demonstrates a direct linkage from low Reynolds …

Development And Validation Of A Sensitive Uplc-Ms/Ms Method For The Quantitation Of [13c]Sucrose In Rat Plasma, Blood, And Brain: Its Application To The Measurement Of Blood-Brain Barrier Permeability, Mohammad K. Miah, Ulrich Bickel, Reza Mehvar

Pharmacy Faculty Articles and Research

Accurate and reproducible measurement of blood-brain barrier (BBB) integrity is critical in the assessment of the pathophysiology of the central nervous system disorders and in monitoring therapeutic effects. The widely-used low molecular weight marker [14C]sucrose is non-specific in the absence of chromatographic separation. The purpose of this study was to develop and validate a sensitive and reproducible LC-MS/MS method for the analysis of stable isotopemodified [13C12]sucrose in brain, plasma, and blood to determine BBB permeability to sucrose. After addition of internal standard (IS, [13C6]sucrose), the marker and IS were recovered from diluted rat blood, plasma, and brain homogenate by protein …

Sexual Behavior Varies Between Same-Race And Different-Race Partnerships: A Daily Diary Study Of Highly Sexually Active Black, Latino, And White Gay And Bisexual Men, Christian Grov, Demetria Cain, H. Jonathan Rendina, Ana Ventuneac, Jeffrey T. Parsons

Publications and Research

Background. Gay and bisexual men (GBM) are at elevated risk for gonorrhea and chlamydia trachomatis (GC/CT). Rectal GC/CT symptoms may be less obvious than urethral, increasing opportunities for undiagnosed rectal GC/CT.

Method. A U.S. national sample of 1,071 GBM completed urethral and rectal GC/CT testing and an online survey.

Results. In total, 6.2% were GC/CT positive (5.3% rectal, 1.7% urethral). We calculated adjusted (for education, race, age, relationship status, having health insurance, and income) odds ratios for factors associated with rectal and urethral GC/CT diagnoses. Age was inversely associated with urethral and rectal GC/CT. Compared to White men, Latinos had …

Marine & Environmental Sciences Faculty Articles

River plumes often feature turbulent processes in the frontal zone and interfacial region at base of the plume, which ultimately impact spreading and mixing rates with the ambient coastal ocean. The degree to which these processes govern overall plume mixing is yet to be quantified with microstructure observations. A field campaign was conducted in a river plume in the northeast Gulf of Mexico in December 2013, in order to assess mixing processes that could potentially impact transport and dispersion of surface material near coastal regions. Current velocity, density, and Turbulent Kinetic Energy Values, ε, were obtained using an Acoustic …
