Green Synthesis And Evaluation Of Catalytic Activity Of Sugar Capped Gold Nanoparticles, Yogesh A. Kherde

Masters Theses & Specialist Projects

Owing to the importance of gold nanoparticles in catalysis, designing of them has become a major focus of the researchers. Most of the current methods available for the synthesis of gold nanoaprticles (GNPs) suffer from the challenges of polydispersity, stability and use of toxic and harmful chemicals. To overcome these limitations of conventional methods, in our present study, we made an attempt to design a method for the green synthesis of monodispersed and stable gold nanoparticles by sugars which act as reducing and stabilizing agent. Characterization of synthesized nanoparticles was done by using various analytical techniques such as transmission electron …

Hair Cortisol As A Biomarker Of Stress In Mindfulness Training For Smokers., Simon B Goldberg, Alison R Manley, Stevens S Smith, Jeffrey M Greeson, Evan Russell, Stan Van Uum, Gideon Koren, James M Davis

College of Science & Mathematics Departmental Research

OBJECTIVES: Stress is a well-known predictor of smoking relapse, and cortisol is a primary biomarker of stress. The current pilot study examined changes in levels of cortisol in hair within the context of two time-intensity matched behavioral smoking cessation treatments: mindfulness training for smokers and a cognitive-behavioral comparison group.

PARTICIPANTS: Eighteen participants were recruited from a larger randomized controlled trial of smoking cessation.

OUTCOME MEASURES: Hair samples (3 cm) were obtained 1 month after quit attempt, allowing for a retrospective analysis of hair cortisol at preintervention and post-quit attempt time periods. Self-reported negative affect was also assessed before and after …

A Novel Web-Based Depth Video Rewind Approach Toward Fall Preventive Interventions In Hospitals, Moein Enayati, Tanvi Banerjee, Mihail Popescu, Marjorie Skubic, Marilyn J. Rantz

Kno.e.sis Publications

Falls in the hospital rooms are considered a huge burden on healthcare costs. They can lead to injuries, extended length of stay, and increase in cost for both the patients and the hospital. It can also lead to emotional trauma for the patients and their families [1]. Having Microsoft Kinects installed in the hospital rooms to capture and process every movement in the room, we deployed our previously developed fall-detection system to detect naturally occurring falls, generate a real-time fall alarm and broadcast it to hospital nurses for immediate intervention. These systems also store a processed and reduced version …

Considering A New Paradigm For Alzheimer’S Disease Research, Gillian R. Langley

Experimentation Collection

Using Alzheimer’s disease as a case study, this review argues that it might be time to consider a new paradigm in medical research and drug discovery. The existing framework is overly dependent on often unvalidated animal models, particularly transgenic mice. Translational success remains elusive and costly late-stage drug failure is common. The conventional paradigm tends to overlook species differences and assumes that animal-based findings are generally applicable to humans. Could pathways-based research using advanced human-specific models probed with new tools, including those of systems biology, take centre stage? The current transition in chemical toxicology to a 21st-century paradigm could be …

Attitudes Of Canadian Pig Producers Toward Animal Welfare, Jeffrey M. Spooner, Catherine A. Schuppli, David Fraser

Farm Animal Welfare Collection

As part of a larger study eliciting Canadian producer and non-producer views about animal welfare, open-ended, semi-structured interviews were used to explore opinions about animal welfare of 20 Canadian pig producers, most of whom were involved in confinement-based systems. With the exception of the one organic producer, who emphasized the importance of a ‘‘natural’’ life, participants attached overriding importance to biological health and functioning. They saw their efforts as providing pigs with dry, thermally regulated, indoor environments where animals received abundant feed, careful monitoring and where prospective disease outbreaks could be minimized and controlled. Emphasis was also placed on low-stress …

Why Are There Eggs?, Stuart A. Newman

NYMC Faculty Publications

A description and update of the "egg-as-novelty" hypothesis is presented. It is proposed that the major animal phylum-characteristic suites of morphological motifs first emerged more than a half-billion years ago in multicellular aggregates and clusters that did not exhibit an egg-soma divergence. These pre-metazoan bodies were organized by "dynamical patterning modules" (DPMs), physical processes and effects mobilized on the new multicellular scale by ancient conserved genes that came to mediate cell-cell interactions in these clusters. "Proto-eggs" were enlarged cells that through cleavage, or physical confinement by a secreted matrix, served to enforce genomic and genetic homogeneity in the cell clusters …

White-Nose Syndrome The Devastating Disease Of Hibernating Bats In North America, Jeremy Coleman

United States Fish and Wildlife Service: Publications

What is white-nose syndrome?

White-nose syndrome (WNS) is a disease affecting hibernating bats. Named for a white fungus that appears on the muzzle and other parts of bats, WNS is associated with extensive mortality of these animals in eastern North America. First documented in New York in the winter of 2006-2007, WNS has spread rapidly across the eastern and midwestern United States and eastern Canada, and evidence of the fungus that causes WNS has been detected as far south as Mississippi.

Bats with WNS act strangely during cold winter months, including flying outside during the day and clustering near the …

Providing An Evidence-Based Medical Screening Examination On Patients Who Present To The Emergency Department With Non-Emergent Complaints: A Quality Improvement Initiative, Joyce Jeffries

Regis University Student Publications (comprehensive collection)

Problem Emergency Department (ED) overcrowding is a growing concern for hospitals across the US. ED overcrowding contributes to prolonged wait times and an increase in the number of patients who leave before or without being seen (LWBS). The number of patients using the ED for non-emergent complaints is expected to continue to rise and some hospitals are utilizing a different model to deliver care (Nash, Nguyen, & Tillman 2009). The problem statement described in this project is: In (P) adults utilizing the ED for non-emergent complaints at a local hospital in the southern US, (I) will providing a mid-level provider …

Morquio A Syndrome-Associated Mutations: A Review Of Alterations In The Galns Gene And A New Locus-Specific Database, Amelia Morrone, Anna Caciotti, Robert Atwood, Kathryn Davidson, Chaoyi Du, Patricia Francis-Lyon, Paul Harmatz, Matthew Mealiffe, Sean Mooney, Tal Ronnen Oron, April Ryles, Karl A. Zawadzki, Nicole Miller

Nursing and Health Professions Faculty Research and Publications

Morquio A syndrome (mucopolysaccharidosis IVA) is an autosomal recessive disorder that results from deficient activity of the enzyme Nacetylgalactosamine-6-sulfatase (GALNS) due to alterations in the GALNS gene, which causes major skeletal and connective tissue abnormalities and effects on multiple organ systems. The GALNS alterations associated with Morquio A are numerous and heterogeneous, and new alterations are continuously identified. To aid detection and interpretation of GALNS alterations, from previously published research, we provide a comprehensive and upto-date listing of 277 unique GALNS alterations associated with Morquio A identified from 1,091 published GALNS alleles. In agreement with previous findings, most reported GALNS …

Mitochondrial Involvement In Neuronal Cell Death, Josie J. Gray

Electronic Theses and Dissertations

Neuronal cell death via apoptosis or necrosis underlies several devastating neurodegenerative diseases associated with aging. Mitochondrial dysfunction resulting from oxidative or nitrosative stress often acts as an initiating stimulus for intrinsic apoptosis or necrosis. These events frequently occur in conjunction with imbalances in the mitochondrial fission and fusion equilibrium, although the cause and effect relationships remain elusive. In this thesis, I demonstrate in primary rat cerebellar granule neurons (CGNs) that oxidative or nitrosative stress induces an N-terminal cleavage of optic atrophy-1 (OPA1), a dynamin-like GTPase that regulates mitochondrial fusion and maintenance of cristae architecture. This cleavage event is indistinguishable from …

Retigabine Calms Seizure-Induced Behavior Following Status Epilepticus, A M. Slomko, Z Naseer, S S. Ali, J P. Wongvravit, L K. Friedman

NYMC Faculty Publications

In adult rats, intraperitoneal injection of kainate (KA) results in sustained status epilepticus and persistent behavioral comorbidities such as hyperexcitability, anxiety, and altered response to environmental cues. Intrahippocampal KA also results in sustained status epilepticus and continuous high frequency oscillations in the electroencephalograph (EEG), although subsequent behavioral side effects are unknown. We hypothesized that retigabine, a recently discovered anticonvulsant and potent positive modulator of Kv7 channels, may attenuate seizure-induced behavioral abnormalities. Status epilepticus was induced by administration of KA either intraperitoneally (15 mg/kg) or by single intrahippocampal injection (1.0 μg/0.5 μL). After 24 h, half of systemically KA-treated animals that …

Carbon Cycling Dynamics Inferred From Carbon Isotope Sourcing In A Mid-Latitude Karst-Influenced River, Kegan N. Mcclanahan

Masters Theses & Specialist Projects

As ever-increasing levels of carbon dioxide alter the chemistry of the Earth’s atmosphere, understanding the global carbon cycle becomes increasingly important. A particularly important component is the riverine carbon cycle, as rivers are the primary conduits for dissolved inorganic carbon from terrestrial watersheds to ocean basins. Stable carbon isotopes (13C/12C) were collected weekly and input into the mixing model IsoSource to delineate seasonal carbon sourcing along two nested basins in the upper Green River System, Kentucky. In the more siliciclastic upstream catchment, dissolved inorganic carbon (DIC) was primarily derived from soil respiration (34%). Groundwater dissolving carbonate bedrock and carbonate dissolution/precipitation …

Selective Oxidations By Iron(Iii) Porphyrins And Iron(Iii) Corroles, Aaron Dalnamath Carver

Masters Theses & Specialist Projects

The selective oxidation of organic compounds represents a leading technology for chemical industries. They are used in chemical synthesis in the pharmaceutical and petrochemicals industries, and possible the decontamination of harmful substances. However, oxidations reaction are among the most challenging processes to control. Many stoichiometric oxidants with heavy metals are expensive, or toxic maybe both, and therefore unfeasible to be utilized. The ideal processes for catalytic oxidation would use molecular oxygen or hydrogen peroxide as the primary oxygen source, with transition metal catalysts to mimic the predominant oxidation catalysts in Nature, the cytochrome P450 enzymes. This study focuses on the …

Are Local Filters Blind To Provenance? Ant Seed Predation Suppresses Exotic Plants More Than Natives, Dean Pearson, Nadia S. Icasatti, Jose L. Hierro, Benjamin J. Bird

Biological Sciences Faculty Publications

The question of whether species’ origins influence invasion outcomes has been a point of substantial debate in invasion ecology. Theoretically, colonization outcomes can be predicted based on how species’ traits interact with community filters, a process presumably blind to species’ origins. Yet, exotic plant introductions commonly result in monospecific plant densities not commonly seen in native assemblages, suggesting that exotic species may respond to community filters differently than natives. Here, we tested whether exotic and native species differed in their responses to a local community filter by examining how ant seed predation affected recruitment of eighteen native and exotic plant …

Limitations To Estimating Bacterial Cross-Species Transmission Using Genetic And Genomic Markers: Inferences From Simulation Modeling, Julio A. Benavides, Paul C. Cross, Gordon Luikart, Scott Creel

Biological Sciences Faculty Publications

Cross-species transmission (CST) of bacterial pathogens has major implications for human health, livestock, and wildlife management because it determines whether control actions in one species may have subsequent effects on other potential host species. The study of bacterial transmission has benefitted from methods measuring two types of genetic variation: variable number of tandem repeats (VNTRs) and single nucleotide polymorphisms (SNPs). However, it is unclear whether these data can distinguish between different epidemiological scenarios. We used a simulation model with two host species and known transmission rates (within and between species) to evaluate the utility of these markers for inferring CST. …

The Threat Of Terrorism And The Changing Public Discourse On Immigration After September 11, Joshua Woods, C. Damien Arthur

Political Science Faculty Research

This article uses articles from the opinion-leading press to investigate how the news media's repertoire of negative portrayals changed after the September 11 terrorist attacks. It is based on a systematic random sample of 360 articles from two, opinion-leading newspapers---one known for its liberal slant (New York Times) and one known for its conservative slant (Wall Street Journal). The sample is drawn from a large population of articles published over a six-year period (1998-2004). The findings show that the percentage of negative frames involving not only terrorism but also other non-terrorist threats increased significantly after September 11. The elevated frequency …

Identifying Priority Species And Conservation Opportunities Under Future Climate Scenarios: Amphibians In A Biodiversity Hotspot, Kyle Barrett, Nathan P. Nibbelink, John C. Maerz

All Publications

Climate change is driving shifts in the distribution of plants and animals, and prioritizing management actions for such shifts is a necessary but technically difficult challenge. We worked with state agencies in the southeastern United States to identify high-priority amphibian species, to model the vulnerabilities of those species to regional climate change, and to identify long-term climatic refugia within the context of existing conservation lands. Directly interfacing with state natural resource experts ensured that 1) species prioritization schemes extend beyond political boundaries and 2) our models resulted in conservation-relevant applications. We used a correlative model to project midcentury distributions of …

Investigating Local Sustainable Environmental Perspectives Of Kenyan Community Members And Teachers, Cassie Quigley, James Dogbey, S Megan Che, Jeffrey Hallo

Publications

Efforts to conserve and preserve the environment in developing or marginalized locales frequently involve a one-way transfer of knowledge and materials from a source in a more developed location. This situation often degenerates into a short-term donor project which risks little to no long-term impacts on local or indigenous relationships with the environment. This research study with educators in Narok, Kenya investigates the current perspectives of local key stakeholders on the environment and sustainability with the purpose of sharing these understandings among local groups to generate a locally constructed meaning of environmental conservation and sustainability. It is the researchers’ aim …
