Volatile Profiling Distinguishes Streptococcus Pyogenes From Other Respiratory Streptococcal Species, Amalia Z Berna, Joseph A Merriman, Leah Mellett, Danealle K Parchment, Michael G Caparon, Audrey R Odom John

2020-Current year OA Pubs

Sore throat is one of the most common complaints encountered in the ambulatory clinical setting. Rapid, culture-independent diagnostic techniques that do not rely on pharyngeal swabs would be highly valuable as a point-of-care strategy to guide outpatient antibiotic treatment. Despite the promise of this approach, efforts to detect volatiles during oropharyngeal infection have yet been limited. In our research study, we sought to evaluate for specific bacterial volatile organic compounds (VOC) biomarkers in isolated cultures

Background

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produces the coronavirus disease of 2019 (COVID-19), primarily presenting with respiratory symptoms, including cough, shortness of breath, etc. Respiratory failure can present similarly to a COVID-19 infection, and COVID-19 infection can cause respiratory failure. Thus, it is important to study respiratory failure, COVID-19, and the interaction between the two in hopes of improving patient outcomes. In this study, we compared mortality rates in patients admitted with COVID-19, respiratory failure, or both. Mortality rates in our study populations were further scrutinized based on patient age.

Population-Level Dna Study Of Stenotrema And Euchemotrema (Gastropoda: Polygyridae: Stenotrematini) Reveals Majority Of Species Are Poorly Circumscribed, Alexander C. Cooper, Elizabeth A. Bergey, Kathryn E. Perez

School of Integrative Biological & Chemical Sciences Faculty Publications

The North American land snail tribe Stenotrematini (Emberton, 1995) is composed of 40 taxa from the genera Stenotrema (Rafinesque, 1819) and Euchemotrema (Archer, 1939). We conducted the first thorough examination of this group since 1948 by sequencing 196 individuals representing 31 of 40 members of the tribe using a combination of cytochrome c oxidase subunit I (COI) and a portion of the 5.8S gene of the large ribosomal subunit (LSU) with the accompanying internal transcribed spacer (ITS-2) region. We reexamined the validity of this tribe by incorporating new sequences with previous DNA work on the …

Enterprise Architecture In Healthcare Networks: A Systematic Literature Review, Arjen Maris, Stijn Hoppenbrouwers, Jos Van Hillegersberg

Communications of the IIMA

Healthcare organizations collaborate, share knowledge, and need to be accountable to each other. Therefore, healthcare organizations manage a dynamic information system landscape. Enterprise Architecture (EA) is a management tool for aligning these landscapes to the primary information needs that healthcare organizations have. EA is of value in some environments, but it seems to be not well suited to the dynamics of healthcare. Despite the publication of several systematic literature reviews on EA in healthcare, a systematic literature study comparing EA applicability at various levels of cooperation (intra, inter, and network collaboration) is lacking. Therefore, we posed the following research question: …

An Analysis Of Communication For Foster Parents: Interpersonal, Small Group, And Public Speaking Skills Necessary For Foster Parenting, Kaitlyn Randall

Communication and Theater Association of Minnesota Journal

Communication is a core aspect of what foster parents do every day. However, communication research focusing on foster parents is limited. Foster parents should understand interpersonal communication, small group communication, and public speaking. Understanding the basic principles of these communication disciplines will help foster parents succeed in their role. Interpersonal communication creates relationships between the foster parent and child through inclusion, control, and affection. Small group communication aspects of group roles, meeting facilitation, and conflict management are used in interactions with caseworkers. The public speaking skills of preparation and practice are used during court proceedings, orientations, and support groups. Providing …

Machine Learning Faculty Publications

The development of the Internet of Things (IoT) has dramatically expanded our daily lives, playing a pivotal role in the enablement of smart cities, healthcare, and buildings. Emerging technologies, such as IoT, seek to improve the quality of service in cognitive cities. Although IoT applications are helpful in smart building applications, they present a real risk as the large number of interconnected devices in those buildings, using heterogeneous networks, increases the number of potential IoT attacks. IoT applications can collect and transfer sensitive data. Therefore, it is necessary to develop new methods to detect hacked IoT devices. This paper proposes …

Essential Role Of The Amino-Terminal Region Of Drosha For The Microprocessor Function, Amit Prabhakar, Song Hu, Jin Tang, Prajakta Ghatpande, Giorgio Lagna, Xuan Jiang, Akiko Hata

Biology

Drosha is a core component of the Microprocessor complex that cleaves primary-microRNAs (pri-miRNAs) to generate precursor-miRNA and regulates the expression of ∼80 ribosomal protein (RP) genes. Despite the fact that mutations in the amino-terminal region of Drosha (Drosha-NTR) are associated with a vascular disorder, hereditary hemorrhagic telangiectasia, the precise function of Drosha-NTR remains unclear. By deleting exon 5 from the Drosha gene and generating a Drosha mutant lacking the NTR (ΔN), we demonstrate that ΔN is unable to process pri-miRNAs, which leads to a global miRNA depletion, except for the miR-183/96/182 cluster. We find that Argonaute 2 facilitates the processing …

Quantitative Analyses Of T Cell Motion In Tissue Reveals Factors Driving T Cell Search In Tissues, David J. Torres, Paulus Mrass, Janie Byrum, Arrick Gonzales, Dominick N. Martinez, Evelyn Juarez, Emily Thompson, Vaiva Vezys, Melanie E. Moses, Judy L. Cannon

Pathology Research and Scholarship

T cells are required to clear infection, and T cell motion plays a role in how quickly a T cell finds its target, from initial naive T cell activation by a dendritic cell to interaction with target cells in infected tissue. To better understand how different tissue environments affect T cell motility, we compared multiple features of T cell motion including speed, persistence, turning angle, directionality, and confinement of T cells moving in multiple murine tissues using microscopy. We quantitatively analyzed naive T cell motility within the lymph node and compared motility parameters with activated CD8 T cells moving within …

Genomic Insights Into The Mystery Of Mouse Mummies On The Summits Of Atacama Volcanoes, Jay F. Storz, Schuyler Liphardt, Marcial Quiroga-Carmona, Naim M. Bautista, Juan C. Opazo, Guillermo D’Elía, Jeffrey M. Good

Jay F. Storz Publications

Our understanding of the limits of animal life is continually revised by scientific exploration of extreme environments. Here we report the discovery of mummified cadavers of leaf-eared mice, Phyllotis vaccarum, from the summits of three different Andean volcanoes at elevations 6,029–6,233 m above sea level in the Puna de Atacama in Chile and Argentina. Such extreme elevations were previously assumed to be completely uninhabitable by mammals. In combination with a live-captured specimen of the same species from the nearby summit of Volcán Llullaillaco (6,739 m),¹ the summit mummies represent the highest altitude physical records of mammals in the …

The High Pressure Dependence Of X-Ray Induced Decomposition Of Cadmium Oxalate, Adrian F. Lua Sanchez, Petrika Cifligu, Marc Graff, Michael Pravica, Pradip K. Bhowmik, Changyong Park, Egor Evlyukhin

Physics & Astronomy Faculty Research

The high proclivity of x rays to destabilize and distort molecular structures has been previously utilized in the synthesis of novel compounds. Here, we show that x-ray induced decomposition of cadmium oxalate induces chemical and structural transformations only at 0.5 and 1 GPa. Using x-ray diffraction and Raman spectroscopy, the synthesized product is identified as cadmium carbonate with cadmium oxalate remnants, which is stable under ambient conditions. At ambient and >1 GPa pressures, only degradation of the electronic density distribution is observed. The transformation kinetics are examined in terms of Avrami’s model, which demonstrates that despite the necessity of high …

Molecular Mechanisms Underlying Host Immunity In The Drosophila-Parasitoid System And Its Application In A Course-Based Research Experience, Ashley Waring-Sparks

Theses and Dissertations

A functional immune response is essential for the survival of all living organisms. The fruit fly Drosophila melanogaster is a well-established model for studying host immunity as well as metabolic regulation during an immune response. Fruit fly larvae, in nature, are commonly infected by parasitoid wasps whose survival is dependent on the successful parasitization of their host. The immune response that the fly elicits toward the wasp egg is a primitive yet effective process. I characterized the genes induced by a host during infection, identified metabolites present in a host during infection, investigated the role of Ab in the cellular …

Forest Composition Change And Biophysical Climate Feedbacks Across Boreal North America, Richard Massey, Brendan M. Rogers, Logan T. Berner, Sol Cooperdock, Michelle C. Mack, Xanthe J. Walker, Scott J. Goetz

Aspen Bibliography

Deciduous tree cover is expected to increase in North American boreal forests with climate warming and wildfire. This shift in composition has the potential to generate biophysical cooling via increased land surface albedo. Here we use Landsat-derived maps of continuous tree canopy cover and deciduous fractional composition to assess albedo change over recent decades. We find, on average, a small net decrease in deciduous fraction from 2000 to 2015 across boreal North America and from 1992 to 2015 across Canada, despite extensive fire disturbance that locally increased deciduous vegetation. We further find near-neutral net biophysical change in radiative forcing associated …

Turn-On Rhodamine Glycoconjugates Enable Real-Time Glut Activity Monitoring In Live Cells And In Vivo, Monica M.S. Nyansa, Adelina Oronova, Nazar Gora, Micaela Rayne Geborkoff, Nathan Ostlund, Delaney Fritz, Thomas Werner, Marina Tanasova

Michigan Tech Publications

The direct relationship between facilitative glucose transporters (GLUTs) and metabolic diseases opens new avenues for sensing metabolic deregulations and drives the development of molecular probes for GLUT-targeted detection of metabolic diseases. Radiotracer-based molecular imaging probes have been effectively utilized in reporting alterations in sugar uptake as an indication of metabolic deregulations, cancer development, or inflammation. Progress in developing fluorophore-based tools facilitated GLUT-specific analyses using more accessible fluorescence-based instrumentation. However, restrictions on the emission range of fluorophores and the requirement for substantial post-treatments to reduce background fluorescence have brought to light the critical directions for improvement of the technology for broader …

Are We There Yet?, Marion S. Freistadt

LSU Master's Theses

To solve the Climate Crisis, a global Energy Transition is required. The primary contemporary tool for tackling these two massive problems is modeling, both biophysical climate models and IAMS (Integrated Assessment Models) which combine socioeconomic and technological progress with Climate Change. However, the proliferation and complexity of modeling systems make it difficult for most people to contribute substantively to solutions. In particular, stakeholders, policymakers, nonspecialists and activists require sufficient understanding of modeling to impact outcomes.

In this thesis, after summarizing the Climate Crisis and potential Energy Transition solutions, I review current modeling approaches. Models can be considered in terms of …

An Exploration Of Complementary And Alternative Medicine Usage Within The Vietnamese Community In Lincoln, Nebraska, Helen Duong

Honors Program: Senior Projects (Public)

Lincoln, Nebraska is home to over 5,000 Vietnamese refugees and immigrants, many of whom practice complementary and alternative medicine (CAM) as a result of healing traditions passed down through family members. This thesis explores the use of CAM among the Vietnamese population of Lincoln. The study employs an analysis of the literature on CAM among Vietnamese populations and thematic analysis of interviews conducted with members of the Vietnamese community of Lincoln, NE. Interviews explore perceptions of healthcare quality and access within this community as well as investigate the link between CAM and allopathic (Western) medicine. Findings suggest that certain CAM …

Momentary Shame & Executive Function: Negative Self-Attribution As A Precursor To Performance Error, Mary M. Bryan

Master's Theses & Other Graduate Student Works

Individuals who experience momentary shame experiences may attribute a sense of wrongdoing to their identity. Witnessing one's violation of social mores may promote withdrawal, rumination, and/or aggression, which may restrict cognitive processes that affect typical executive function. In particular, task initiation, inhibition, and cognitive flexibility were selected when measuring levels of executive dysfunction. 10 participants were asked to complete shame and executive function pre-screeners, a shame- or neutral-affective writing task, and a real-time executive function measure. Results suggest that those who self-reported higher levels of shame proneness and underwent a shame-affective stimulus may have displayed improved inhibition and cognitive flexibility. …

Re‑Using Food Resources From Failed Honey Bee (Apis Mellifera L.) Colonies And Their Impact On Colony Queen Rearing Capacity, Rogan Tokach, Autumn H. Smart, Judy Wu-Smart

Department of Entomology: Faculty Publications

For over a decade, beekeepers have experienced high losses of honey bee (Apis mellifera L.) colonies due to a variety of stressors including pesticide exposure. Some of these chemical stressors may residually remain in the colony comb and food resources (pollen and nectar) of failed colonies and be later re-used by beekeepers when splitting and building back new colonies. The practice of re-using comb from previously perished colonies (termed “deadout”) is common in beekeeping practice, but its role in affecting colony health is not well understood. Here, we evaluate the impact of reused, pesticide-contaminated “deadout” combs on colony function …

Causal Models And Causal Modelling In Obesity: Foundations, Methods And Evidence, Roger S Zoh, Xiaoxin Yu, Philip Dawid, George Davey Smith, Stephen J French, David B Allison

Children’s Nutrition Research Center Staff Publications

Discussing causes in science, if we are to do so in a way that is sensible, begins at the root. All too often, we jump to discussing specific postulated causes but do not first consider what we mean by, for example, causes of obesity or how we discern whether something is a cause. In this paper, we address what we mean by a cause, discuss what might and might not constitute a reasonable causal model in the abstract, speculate about what the causal structure of obesity might be like overall and the types of things we should be looking …

School of Integrative Biological & Chemical Sciences Faculty Publications

Animals must learn to ignore stimuli that are irrelevant to survival and attend to ones that enhance survival. When a stimulus regularly fails to be associated with an important consequence, subsequent excitatory learning about that stimulus can be delayed, which is a form of nonassociative conditioning called ‘latent inhibition’. Honey bees show latent inhibition toward an odor they have experienced without association with food reinforcement. Moreover, individual honey bees from the same colony differ in the degree to which they show latent inhibition, and these individual differences have a genetic basis. To investigate the mechanisms that underly individual differences in …

3d Musculoskeletal Analysis Of The Rhea Americana Forelimb And Implications For The Evolution Of Avian Flight, Sarah Elizabeth Guzinski

USF Tampa Graduate Theses and Dissertations

To understand the evolutionary gain, and loss, of avian powered flight, attention must be paid to the wing morphology of species across these transitions. However, paleognaths, while being the most well-known flightless birds, have greatly understudied forelimbs. Additionally, current literature regarding their forelimb anatomy generally lacks a three-dimensional (3D), biomechanical approach. Among the flightless paleognaths, the rhea is notable in having the least reduced forelimb. Though not used for flight, the wings of rheas are used in other behaviors such as courtship and threat display, as well as nest defense. In this study, I investigate the forelimb anatomy of an …

Stable Isotope Analysis On Yellowfin And Blackfin Tuna Eye Lenses Reveals Life History Patterns In The Gulf Of Mexico, Kylee M. Rullo

USF Tampa Graduate Theses and Dissertations

Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of effective marine resource management. A number of methods are currently available for tracking movements of pelagic migratory species, including the use of conventional and electronic tags. However, tagging campaigns can take years to provide useful data, can be expensive, and only capture a portion of a fish’s lifetime. For this project, I used stable-isotopic ratios of nitrogen (δ15N) and carbon (δ13C) in metabolically inert, chronologically-layered fish-eye lenses to explore lifetime movement and trophic patterns of yellowfin tuna (Thunnus albacares) and blackfin tuna (Thunnus atlanticus) in the …
