Reactive Oxygen Species-Induced Release Of Signalling Factors In Irradiated Cells Triggers Membrane Signalling And Calcium Influx In Bystander Cells., Fiona Lyng, Orla L. Howe, Brendan Mcclean

Articles

Purpose: The aim of this study was to elucidate the sequence of very early bystander signalling events and to determine the role of the different signaling molecules in both the production of the bystander signal and the response to this signal.

Materials and Methods: Human keratinocytes (HaCaT cell line) were irradiated (0.005, 0.05 and 0.5 Gy) using a cobalt 60 teletherapy unit, the medium was harvested one hour post irradiation and transferred to recipient HaCaT cells. Membrane permeability and levels of calcium, reactive oxygen species and nitric oxide were measured in the recipient cells immediately after the addition of irradiated …

Bridging The Marine–Terrestrial Disconnect To Improve Marine Coastal Zone Science And Management, Benjamin I. Ruttenberg, Elise F. Granek

Environmental Science and Management Faculty Publications and Presentations

Coastal zone ecosystems sit between larger terrestrial and marine environments and, therefore, are strongly affected by processes occurring in both systems. Marine coastal zone systems provide a range of benefits to humans, and yet many have been significantly degraded as a result of direct and indirect human impacts. Management efforts have been hampered by disconnects both between management and scientific research and across linked marine–terrestrial systems. Management jurisdictions often start or end at the shoreline, and multiple agencies at different levels of government often have overlapping or conflicting management goals or priorities, or suffer from a lack of knowledge or …

Comprehensive Seagrass Restoration Planning In Southwest Florida: Science, Law And Management, Althea S. Hotaling, R. Benjamin Lingle, Thomas T. Ankersen

UF Law Faculty Publications

In coastal Florida, the development and maintenance of docks, marinas, and channels frequently cause destruction of seagrass beds. Seagrass loss is accompanied by a loss of the ecosystem services the beds provide, such as sediment stabilization, water filtration, protection from storms, and habitat and nursery grounds for fish species. The current legal framework for seagrass protection and the implementation of mitigation for seagrass loss could be improved. In this Article, the authors argue that policymakers could revise the Uniform Mitigation Assessment Method to include more assessments related specifically to the ecology of seagrass beds and their ecosystem services. Seagrass mitigation …

Patents, Genetically Modified Foods, And Ip Overreaching, Elizabeth A. Rowe

UF Law Faculty Publications

Genetically engineered plants and animals have become and will continue to constitute a large part of the food we consume. The United States is the world's largest producer of genetically modified foods, making American consumers the most exposed population to these products. Agricultural biotechnology patents spur and support innovation. Accordingly, patent law is one of the main contributors to this phenomenon that has changed not only the kinds of food we eat, but the nature of the agri-business industry that produces these foods. This Article takes on an area of concern involving the patenting of food that has remained unexplored: …

Patents, Presumptions, And Public Notice, Timothy R. Holbrook

Indiana Law Journal

Patents are peculiar legal instruments in that they contain both technical and legal information. This Janus-like nature of the documents is important because they serve the legal purpose of affording the owner the right to exclude others from practicing the invention, and third parties need to be able to assess the scope of that right. At the same time, through the patent’s disclosure, the document is intended to contribute to the storehouse of technical knowledge. Superficially, patents are generally viewed through the eyes of the hypothetical person having ordinary skill in the art (PHOSITA), patent law’s “reasonable person.” Unfortunately, the …

The Effects Of Stereotype Threat On State Levels Of Stigma Consciousness And Overall Performance On A Stereotype-Relevant Task, Gwenith Blount-Nuss

College of Graduate Studies: Theses & Dissertations

Situational anxiety surrounding performance has been shown to adversely impact task performance by members of negatively stereotyped groups, creating a stereotype threat effect. This study tested the hypothesis that the anticipation of being stereotyped, known as stigma consciousness, is one of many contributing factors to the expression of stereotype threat effects. One area in which stereotype threat has been shown to exist is in the domain of mathematics, with females being negatively stereotyped in the subject and often underperforming relative to males. In this study, male and female participants were presented with a stereotype prime manipulation and then asked to …

Galvanic Corrosion Between Various Combinations Of Orthodontic Brackets And Archwires, Arash Bakhtari, T. Gerard Bradley, William K. Lobb, David W. Berzins

School of Dentistry Faculty Research and Publications

Introduction: The purpose of this study was to compare galvanic currents generated by different combinations of commonly used brackets and archwires.

Methods: As-received stainless steel, nickel-titanium, and betatitanium wires were coupled to stainless steel and titanium brackets in an artificial saliva medium. The galvanic current and amount of charge transferred for each pair were monitored with a zero resistance ammeter for 10 hours.

Results: Two-way analysis of variance (ANOVA) showed a significant difference in charge and galvanic currents when factored for type of bracket (P\0.001), but no significant difference between them when factored by type of wire (P .0.05). Specifically, …

Reward, Punishment, And Cooperation: A Meta-Analysis, Daniel Balliet, Laetitia B. Mulder, Paul A. M. Van Lange

Research Collection School of Social Sciences

How effective are rewards (for cooperation) and punishment (for noncooperation) as tools to promote cooperation in social dilemmas or situations when immediate self-interest and longer term collective interest conflict? What variables can promote the impact of these incentives? Although such questions have been examined, social and behavioral scientists provide different answers. To date, there is no theoretical and/or quantitative review of rewards and punishments as incentives for cooperation in social dilemmas. Using a novel interdependence-theoretic framework, we propose that rewards and punishments should both promote cooperation, and we identify 2 variables-cost of incentives and source of incentives-that are predicted to …

Jury 2.0, Caren Myers Morrison

UC Law Journal

When the Framers drafted the Sixth Amendment and provided that the accused in a criminal case would have the right to a speedy and public trial by an “impartial jury,” it is unlikely that they imagined the members of that impartial jury becoming Facebook friends during deliberations, or running the defendant’s name through Google during trial. But in the past few years, such cases have increasingly been making headlines. The impact of the Internet on the functioning of the jury has generated a lot of press, but has not yet attracted scholarly attention. This Article is the first to focus …

Flexible Memory Networks, Carina Curto, Anda Degeratu, Vladimir Itskov

Department of Mathematics: Faculty Publications

Networks of neurons in some brain areas are flexible enough to encode new memories quickly. Using a standard firing rate model of recurrent networks, we develop a theory of flexible memory networks. Our main results characterize networks having the maximal number of flexible memory patterns, given a constraint graph on the network’s connectivity matrix. Modulo a mild topological condition, we find a close connection between maximally flexible networks and rank 1 matrices. The topological condition is H₁(X;Z) = 0, where X is the clique complex associated to the network’s constraint graph; this condition is …

Use Of Cognitive Artifacts In Chemistry Learning, Ilker Yengin

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

In everyday life, we interact with cognitive artifacts to receive and/or manipulate information so as to alter our thinking processes. CHEM/TEAC 869Q is a distance course that includes extensive explicit instruction in the use of a cognitive artifact. This study investigates issues related to the design of that online artifact. In order to understand design implications and how cognitive artifacts contribute to students’ thinking and learning, a qualitative research methodology was engaged that utilized think aloud sessions.  Participants’ described constrained and structured cognitive models while using the artifact.  The study also was informed by interviews and researcher's field notes. A …

Mourning Dove Population Status, 2011, Mark Seamans, Keri Parker, Todd A. Sanders

United States Fish and Wildlife Service: Publications

This report summarizes information on abundance and harvest of mourning doves collected annually in the United States. For abundance, we report primarily on trends in the number of doves heard per route from the Mourning Dove Call-count Survey (CCS), but also include trends in doves seen per route from the CCS and birds heard and seen per route from the all-bird Breeding Bird Survey (BBS). Harvest and hunter participation are estimated from the Migratory Bird Harvest Information Program (HIP). The CCS-heard data provided evidence that abundance of doves decreased in all three dove management units (Eastern [EMU], Central [CMU], and …

Disability Rights, Welfare Law, Mark C. Weber

Cardozo Law Review

This Article asks how disability rights ideas can be reconciled with - and might transform - the law of public assistance. The social model of disability forms the basis of most disability rights thinking. This model recognizes that impairments do not by themselves disable, but disability instead arises from a dynamic between a person's physical and mental conditions and society's environmental and attitudinal barriers: Paraplegia does not cause disability but for stairs, curbs, and human attitudes that limit accessibility. The social model focuses on changing the environment; its close corollary, the civil rights approach to disability, looks to anti-discrimination law …

Sunday Driver/Jip3 Binds Kinesin Heavy Chain Directly And Enhances Its Motility, Faneng Sun, Chuanmei Zhu, Ram Dixit, Valeria Cavalli

Biology Faculty Research

Neuronal development, function and repair critically depend on axonal transport of vesicles and protein complexes, which is mediated in part by the molecular motor kinesin‐1. Adaptor proteins recruit kinesin‐1 to vesicles via direct association with kinesin heavy chain (KHC), the force‐generating component, or via the accessory light chain (KLC). Binding of adaptors to the motor is believed to engage the motor for microtubule‐based transport. We report that the adaptor protein Sunday Driver (syd, also known as JIP3 or JSAP1) interacts directly with KHC, in addition to and independently of its known interaction with KLC. Using an in vitro motility assay, …

Beyond Jeopardy And Lectures: Using Microsoft Powerpoint As A Game Tool To Teach Science, Jason Paul Siko, Michael K. Barbour, Sacip Toker

Education Faculty Publications

To date, research involving homemade PowerPoint games as an instructional tool has not shown statistically significant gains in student performance. This paper examines the results of a study comparing the performance of students in a high school chemistry course who created homemade PowerPoint games as a test review with the students who used a traditional study guide on two separate unit tests. Students scored significantly higher on one of the two unit tests; however, there was no difference in performance between students who created games multiple times. This was the first time a significant difference has been reported when using …

Structure And Optical Properties Of Self-Assembled Multicomponent Plasmonic Nanogels, Tao Cong, Satvik N. Wani, Peter Anthony Paynter, Radhakrishna Sureshkumar

Biomedical and Chemical Engineering - All Scholarship

Multicomponent plasmonic nanogels (PNGs) capable of broadband absorption of light in the 400-700 nm wavelength range were synthesized by the self-assembly of metal nanoparticles with wormlike surfactant micelles. Small angle x-ray scattering and rheological experiments suggest that the nanoparticles bridge micelle fragments to aid the formation a stable gel phase with exceptional color uniformity. Their optical absorbance could be robustly tuned by changing the nanoparticle type (Au/Ag), size, shape, and/or concentration. The PNGs have relatively low viscosity and are thermoreversible. Potential applications to the manufacturing of coatings and interfaces for solar energy harvesting and reconfigurable optical devices can be envisioned.

Effects Of The Herbicide Atrazine On The Behavior Of The Checkered Gartersnake (Thamnophis Marcianus), Katie Chamberlain

Biology Theses

Atrazine is one of the most commonly used herbicides in the United States and one of the most popular weed-killers worldwide, being utilized in over 80 countries. Despite the effectiveness of atrazine, there has been growing concern over the potential harmful effects this chemical may have on non-target species exposed to this chemical. Few studies, however, have been performed on the effects of this chemical on reptiles, in particular snakes. This study examined the effects of environmentally relevant concentrations of atrazine on the foraging, antipredator, thermoregulatory, and courtship behaviors of the checkered gartersnake (Thamnophis marcianus). Effects of atrazine appeared negligible …

Propagule Pressure And Introduction Pathways Of Bromus Tectorum (Cheatgrass; Poaceae) In The Central United States, Temsha D. Huttanus, Richard N. Mack, Stephen J. Novak

Biology Faculty Publications and Presentations

An introduced species' propagule pressure strongly influences the genetic diversity and evolutionary potential of its descendants and even the likelihood of biological invasion. We examined population genetic consequences arising from introduction of the invasive annual grass Bromus tectorum into the central United States (U.S.). The origin and frequency of introductions were investigated by assembling allozyme diversity data from 60 widely spaced populations. At least five introduction events contributed to the grass’s genetic diversity in the central U.S. Populations in this region have fewer alleles (30 vs. 43) and polymorphic loci (5 vs. 13) than native populations, evidence of a genetic …

The Effects Of Arbuscular Mycorrhizal (Am) Fungal And Garlic Mustard Introductions On Native Am Fungal Diversity, Alexander M. Koch, Pedro M. Antunes, Kathryn Barto, Don Cipollini, Daniel L. Mummey, John N. Klironomos

Biological Sciences Faculty Publications

Introduced, non-native organisms are of global concern, because biological invasions can negatively affect local communities. Arbuscular mycorrhizal (AM) fungal communities have not been well studied in this context. AM fungi are abundant in most soils, forming symbiotic root-associations with many plant species. Commercial AM fungal inocula are increasingly spread worldwide, because of potentially beneficial effects on plant growth. In contrast, some invasive plant species, such as the non-mycorrhizal Alliaria petiolata, can negatively influence AM fungi. In a greenhouse study we examined changes in the structure of a local Canadian AM fungal community in response to inoculation by foreign AM fungi …

Synthesis And Characterization Of Tethered Poly(N-Isopropylacrylamide) For Quantitative Cell Adhesion Studies, Phanindhar J. Shivapooja

Chemical and Biological Engineering ETDs

Environmentally responsive (or smart') polymers represent a new approach for controlling biofouling release. Poly(N-isopropylacrylamide) (PNIPAAm) is a thermo responsive polymer that can potentially be used to control biofouling, as it exhibits a change in its relative hydrophobicity above and below its lower critical solution temperature (LCST ~ 32\uf0b0C). This thesis reports on grafted PNIPAAm brushes, synthesized using a relatively simple and rapid method which allows atom transfer radical polymerization (ATRP) in presence of air. In this study the structure, purity and thermally responsive behavior of grafted brushes have been characterized using X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectroscopy, Fourier …

Children’S Perceptions Of Intimate Partner Violence: Causes, Consequences, And Coping, Renee L. Deboard-Lucas, John H. Grych

Psychology Faculty Research and Publications

Children’s appraisals of conflictual and aggressive parental interactions mediate their effect on children’s adjustment. Previous studies have relied almost exclusively on self report questionnaires to assess appraisals; consequently we know little about perceptions that occur naturally when children witness interparental aggression. This study employed a semistructured interview to assess the thoughts and feelings of 34 children (ages 7–12) whose mothers were receiving services at domestic violence agencies, and mothers reported on interparental aggression that took place in the home. Children’s thoughts centered on consequences and efforts to understand why fights occurred. They generally viewed their mother’s partner as responsible for …
