Understanding Of Functions Of Selenoproteins And Dietary Selenium By Using Animal Models, Marina V. Kasaikina

Department of Biochemistry: Dissertations, Theses, and Student Research

Selenium (Se) is a trace element that is incorporated into proteins in the form of the 21^st amino acid, selenocysteine (Sec). Se supplementation was reported to have beneficial roles in prevention of cardiovascular and muscle disorders, cancer prevention and enhancement of the immune function. However, recent studies also showed that excessive dietary Se increases the risk of development of type 2 diabetes mellitus. Thus, better understanding of Se and selenoprotein functions is required. We used three approaches to address this problem.

First, we used high-throughput sequencing to examine composition of the gut microflora in mice maintained on selenium-deficient, selenium-sufficient, …

Preschool Predictors Of Social Problem-Solving And Their Relations To Social And Academic Adjustment In Early Elementary School, Olga Lydia Walker

Open Access Dissertations

The current study took a multi-method approach to examine the influence of temperament on children’s social problem solving (SPS) abilities and, in turn, whether SPS skills are a mechanism through which early temperament influences later social and academic adjustment. Participants included 270 children. Maternal reports of temperament were collected when the children were 2, 3, and 4 years old. At age 5, children were observed while interacting with an unfamiliar peer during an SPS task. At age 7, children were directly assessed on their academic achievement and completed measures of social adjustment. Both reactive and self-regulatory aspects of temperament related …

Predator-Induced Demographic Shifts In Coral Reef Fish Assemblages, Benjamin I. Ruttenberg, Scott L. Hamilton, Sheila M. Walsh, Mary K. Donovan, Alan Friedlander, Edward Demartini, Enric Sala, Stuart A. Sandin

Biological Sciences

In recent years, it has become apparent that human impacts have altered community structure in coastal and marine ecosystems worldwide. Of these, fishing is one of the most pervasive, and a growing body of work suggests that fishing can have strong effects on the ecology of target species, especially top predators. However, the effects of removing top predators on lower trophic groups of prey fishes are less clear, particularly in highly diverse and trophically complex coral reef ecosystems. We examined patterns of abundance, size structure, and age-based demography through surveys and collection-based studies of five fish species from a variety …

What Is New For An Old Molecule? Systematic Review And Recommendations On The Use Of Resveratrol, Ole Vang, Nihal Ahmad, Karen Brown, Anna Csiszar, Thomas Szekeres, Thomas Walle, Joseph M. Wu

NYMC Faculty Publications

BACKGROUND: Resveratrol is a natural compound suggested to have beneficial health effects. However, people are consuming resveratrol for this reason without having the adequate scientific evidence for its effects in humans. Therefore, scientific valid recommendations concerning the human intake of resveratrol based on available published scientific data are necessary. Such recommendations were formulated after the Resveratrol 2010 conference, held in September 2010 in Helsingør, Denmark.

METHODOLOGY: Literature search in databases as PUBMED and ISI Web of Science in combination with manual search was used to answer the following five questions: (1)Can resveratrol be recommended in the prevention or treatment of …

The Effect Of Adding Organic Polymers To Ca-Sr-Zn-Si Glass Polyalkenoate Cement, A. Coughlan, N. M. Cummins, A. W. Wren, Mark R. Towler

Chemical and Biochemical Engineering Faculty Research & Creative Works

To conclude, the addition of polymers to GPCs resulted in little change to the Tw and Ts, however the compressive strength was found to decrease slightly. ASAP tests revealed that the cements may undergo some structural changes as a result of these additions. In the future perhaps the addition of organic polymers suspended in the liquid phase as part of the cement may yield improved results in this type of study. © 2011 IEEE.

Optimization Of A Tri-Layered Vascular Graft: The Influence Of Cellular And Mechanical Properties, Michael Mcclure

Theses and Dissertations

Electrospinning is a polymer processing technique which allows for the production of nano to micro size fibers and scaffolds which can be composed of numerous synthetic biodegradable materials and natural biopolymers. Natively, elastin and collagen are the main components of vascular tissue. Arranged in a tri-layered structure, they create a specific mechanical environment that can withstand the rigors of circulation. The goal of this study was to develop a mechanically ‘biomimicking’ vascular graft composed of three distinct layers through the process of electrospinning. We hypothesize that the use of bioactive agents such as elastin, collagen, and silk to supplement poly(caprolactone) …

Solar Warning Architecture For Manned Missions To Mars, James S. Bohren, John K. Howard

Theses and Dissertations

Solar radiation storms represent a dire threat to manned interplanetary space travel. Earth's current solar forecasting architecture is Earth-focused and insufficient to provide timely warnings to a manned mission to Mars, therefore a "best value" solar warning architecture must be identified. A total of 14 solar warning architectures were developed by varying 5 solar sensor locations, 2 processing locations, and 2 communications strategies. Using Satellite Tool Kit, performance of the candidate architectures in terms of Warning Time and Solar Coverage was quantified during a Mars mission scenario based on NASA's Design Reference Architecture 5.0. Cost of each candidate architecture was …

Context Aided Tracking With Adaptive Hyperspectral Imagery, Andrew C. Rice

Theses and Dissertations

A methodology for the context-aided tracking of ground vehicles in remote airborne imagery is developed in which a background model is inferred from hyperspectral imagery. The materials comprising the background of a scene are remotely identified and lead to this model. Two model formation processes are developed: a manual method, and method that exploits an emerging adaptive, multiple-object-spectrometer instrument. A semi-automated background modeling approach is shown to arrive at a reasonable background model with minimal operator intervention. A novel, adaptive, and autonomous approach uses a new type of adaptive hyperspectral sensor, and converges to a 66% correct background model in …

The Early Eocene Equable Climate Problem Revisited, Matthew Huber, R. Caballero

Department of Earth, Atmospheric, and Planetary Sciences Faculty Publications

The early Eocene "equable climate problem", i.e. warm extratropical annual mean and above-freezing winter temperatures evidenced by proxy records, has remained as one of the great unsolved problems in paleoclimate. Recent progress in modeling and in paleoclimate proxy development provides an opportunity to revisit this problem to ascertain if the current generation of models can reproduce the past climate features without extensive modification. Here we have compiled early Eocene terrestrial temperature data and compared with climate model results using a consistent and rigorous methodology. We test the hypothesis that equable climates can be explained simply as a response to increased …

Intimate Immensity, Henrik Søderstrøm

Theses

The small house that comprises my visual thesis, made of simple materials reclaimed from junk piles and old houses, was made as worship to the God who spoke the world into existence. This writing is a playful counterpart to my artwork. Water has an amazing ability to transpose itself fluidly across borders, from the atmosphere to the ground to the cells in your body. Its movement is defiant of divisions as it carries nutrients through layers of compost, from rotting biomass to new sprouts. My process of absorbing and using materials is inspired by this cycling. I am interested in …

Design And Characterization Of A Space Based Chromotomographic Hyperspectral Imaging Experiment, Jason D. Niederhauser

Theses and Dissertations

This research focuses upon the design, analysis and characterization of several systems related to a spacebased chromotomographic experiment (CTEx), a hyperspectral imager, currently in development at the Air Force Institute of Technology. Three interrelated subject-areas were developed. The initial focal point was a generic, system-level mechanical layout and integration analysis of the space-based instrument. The scope of this work was intended to baseline the space-based system design in order to allow for further trade-space refinement and requirements development. Second, development of an iteration upon the ground-based version of CTEx was accomplished in an effort to support higher-fidelity field data-collection. This …

Lady Libertines, Female Fops, And Lady Julia Fulbank: Aphra Behn's Extraordinary Female Characters., Sarah Audine Amundsen

Theses and Dissertations

Aphra Behn has, throughout her life and subsequent years, been both demonized as a writer of bawdy and licentious plays and poetry as well as being hailed as the forerunner of female writers. She was a woman writing in a man's world, and not only survived the experience, but was exceptionally successful in her efforts. While so little is known about her background, the numerous plays she has left behind demonstrate a skilled author in many forms, as well as a creative and innovative storyteller. This thesis will examine how Behn used the traditional theatrical forms of the time and …

Psychostimulants As Cognitive Enhancers: The Prefrontal Cortex, Catecholamines And Attention Deficit Hyperactivity Disorder, Craig Berridge, David M. Devilbiss

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Psychostimulants exert behavioral-calming and cognition-enhancing actions in the treatment of attention deficit hyperactivity disorder (ADHD). Contrary to early views, extensive research demonstrates that these actions are not unique to ADHD. Specifically, when administered at low and clinically-relevant doses, psychostimulants improve a variety of behavioral and cognitive processes dependent on the prefrontal cortex (PFC) in subjects with and without ADHD. Despite the longstanding clinical use of these drugs, the neural mechanisms underlying their cognition-enhancing/therapeutic actions have only recently begun to be examined. At behaviorally-activating doses, psychostimulants produce large and widespread increases in extracellular levels of brain catecholamines. In contrast, cognition-enhancing doses …

Journal of Marine Science and Technology–Taiwan

A 26-hr acoustic observation was carried out on board of the “Ocean Research II” in the Kuroshio waters at 123°09.027'E, 25°05.019'N from August 4 to 5, 2007. Acoustic volume scattering strengths (SVs) were collected by a scientific echo sounder (EK500, 38 kHz) and diel variations of sound scattering layer were analyzed. The maximum SV of surface scattering layers (SSL) around 20~80 m was observed after dawn, and mean SVs of SSL in nighttime was about -68 dB, 8 dB higher than that of daytime. Two deep scattering layers (DSL) were found in daytime at depth of 400~500 m and 600~700 …

Development Of New Strategies For Expeditious Oligosaccharide Synthesis, Sophon Kaeothip

Dissertations

The important role that carbohydrates play in biology and medicine has been the major incentive for devising new methods for chemical and enzymatic glycosylation. The chemical approach to oligosaccharides involves multiple synthetic steps and the development of new strategies that allow for streamlining the synthesis of these complex biomolecules is a significant area of research. The aim of this doctoral dissertation is to develop new reagents and efficient methodologies for oligosaccharide synthesis. It was found that siver(I) tetrafluoroborate can be used as a powerful activator of various glycosyl donors for oligosaccharide synthesis. This study evolved into the development of a …

The Family: What Is To Be Done?, Scott Yenor

Political Science Faculty Publications and Presentations

We have seen how the logic of contract and the movement to conquer nature have resulted in a triumph of autonomy and the demise of family. The family thus stands in need of a defense. Defense of the family means defense of an institution, and that defense requires some defense of the nature that these institutions react to and reflect. This is where contemporary advocates have focused their attention. Both the modern principles—the principle of contract and the move to conquer nature—are partial truths, and it is best to understand how they each fit into a proper understanding of married …
