Periodically Disturbing Biofilms Reduces Expression Of Quorum Sensing-Regulated Virulence Factors In Pseudomonas Aeruginosa, Laura Garcia-Dieguez, Gabriela Diaz-Tang, Estefania Marin Meneses, Vanessa Cruise, Ivana M. Barraza, Travis J.A. Craddock, Robert P. Smith

Biology Faculty Articles

Pseudomonas aeruginosa uses quorum sensing to regulate the expression of virulence factors. In static environments, spatial structures, such as biofilms, can increase the expression of these virulence factors. However, in natural settings, biofilms are exposed to physical forces that disrupt spatial structure, which may affect the expression of virulence factors regulated by quorum sensing. We show that periodically disturbing biofilms composed of P. aeruginosa using a physical force reduces the expression of quorum sensing-regulated virulence factors. At an intermediate disturbance frequency, the expression of virulence factors in the las, rhl, and pqs regulons is reduced. Mathematical modeling suggests that perturbation …

The Emancipatory Praxis Of Peace And Conflict Studies: The Field Of Genocide Studies, Daniel Rothbart, Douglas Irvin-Erickson

Peace and Conflict Studies

The field of Peace and Conflict Studies (PCS) was launched in the mid-twentieth century with revolutionary aspirations for explaining, describing and understanding protracted violent conflicts. The field’s architects called for inquiry into the “whole person” of conflict actors that required inquiry into the social, psychological and political spheres of their lives. But the proposed research perspectives for carrying out such inquiry were devoid of revolutionary prescription. Regarding such perspectives, they set the stage that continues to this day for disciplinary conservatism by invoking research traditions from the positivist social sciences and from the interpretative social sciences. A third research tradition …

Reframing The Ontology Of Peace Studies, Anders Reagan

Peace and Conflict Studies

The academic field of peace studies suffers from a lack of ontological clarity, with peace researchers widely disagreeing on how to define “peace.” This internal incoherence has far-reaching implications for peace study’s scope, theories, and methodologies, and by extension, for peace practice in general. This article explores the possibility that at least part of this incoherence may be due to a fundamental misreading of peace study’s central object of study. Despite significant disagreement between peace researchers on a standardized definition of peace, there seems to be overwhelming consensus that "peace" – in all its varied academic conceptualizations – always relates …

Ecomorphology Of A Predatory Deep-Sea Fish Family: Does Trophic Specialization Drive Hyperspeciation?, Ryan P. Mcgonagle, David Kerstetter, Danté Fenolio, Tracey Sutton

Marine & Environmental Sciences Faculty Articles

Two of the main drivers of speciation among aquatic vertebrates are physical isolation (e.g., lakes and streams) and micro-niche availability (e.g., tropical reefs). In both regards, the mesopelagic domain of the open ocean, Earth’s second largest cumulative ecosystem (behind only the bathypelagic domain), would seem retardant. Ocean circulation makes isolation rare on both contemporary and geological time/space scales, and the lack of substrate precludes stable micro-niches. Paradoxically, some pelagic taxa demonstrate much higher-than-expected species richness on regional scales. A prime example is the dragonfish family Stomiidae, the most speciose family of mesopelagic fishes, owing largely to the subfamily Melanostomiinae (scaleless …

I Want To Be A Teacher But The Profession Won’T Let Me: How A Criminal Record Alters A Black Man’S Teaching Aspirations, Terrence S. Mctier Jr., Cameron Beatty

The Qualitative Report

There is a shortage of Black men pursuing and or entering the pre-K-12 teaching profession. Some of the causes for the lack of Black men in the teaching profession stems from burnout, the school-to-prison pipeline, bad experiences as students, and a myriad of other reasons. We believe that Black men having a criminal record has not been fully explored or brought to the forefront as a major issue amongst the teaching profession and teacher preparation programs. To highlight this issue, we highlight and center the experience of one Black male who wanted to become an elementary reading teacher but was …

Phylogeny And Taxonomy Of Himerometroidea (Echinodermata: Crinoidea), Kristian H. Taylor, Gregory W. Rouse, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

Himerometroidea is a clade of chiefly shallow-water, tropical, feather-star crinoids that is currently divided, based on morphology, into four families comprising 119 extant species in 31 genera. Our molecular phylogenetic results, based on three mitochondrial (CO1, 16S, CytB) and two nuclear (ITS and 28S) markers for 55 accepted species in 23 of the extant genera, allow for six clades within Himerometroidea to be given family ranks. Maximum parsimony, maximum likelihood, and Bayesian inference analyses recovered largely congruent topologies with varying nodal support. A new classification revises generic placements among five families: Himerometridae, Colobometridae, and Mariametridae, all retained, and Pontiometridae and …

Leg ulcers are a common and often serious problem in older adults. Underlying conditions that increase risk include age-related increases in chronic venous insufficiency, peripheral artery disease, connective tissue and autoimmune conditions, reduced mobility, and diabetes mellitus (DM). Geriatric patients have a higher risk of multiple wound-related complications including infection, cellulitis, ischemia, and gangrene, any of which may lead to further complications including amputation. The very presence of these lower extremity ulcers in the elderly negatively impacts their quality of life and ability to function. Understanding and early identification of the underlying conditions and wound features are important for effective …

Heavy Metal Content In Eggs From Wild And Managed-Care Humboldt Penguins, Mya Daniels-Abdulahad

All HCAS Student Capstones, Theses, and Dissertations

The Humboldt penguin, Spheniscus humboldti, has been recognized as a Vulnerable species (IUCN) for nearly two decades, with annual population declines of more than 10% largely attributed to pervasive anthropogenic activity occurring throughout the species’ range of Peru and Chile. Due to recent mining expansions near the species’ largest Peruvian rookery, located at the Punta San Juan (PSJ) reserve, the exposure of breeding individuals to elevated concentrations of trace elements (e.g., heavy metals) in the marine environment is a preeminent concern. While heavy metal toxicity is dependent on metal species, dose, route of exposure, and the physiologic parameters of …

Interactions Between Metabolism And Growth Can Determine The Co-Existence Of Staphylococcus Aureus And Pseudomonas Aeruginosa, Camryn Pajon, Marla C. Fortoul, Gabriela Diaz-Tang, Estefania Marin Meneses, Ariane R. Kalifa, Elinor Sevy, Taniya Mariah, Brandon Toscan, Maili Marcelin, Daniella M. Hernandez, Melissa M. Marzouk, Allison J. Lopatkin, Omar T. Eldakar, Robert Smith

Biology Faculty Articles

Most bacteria exist and interact within polymicrobial communities. These interactions produce unique compounds, increase virulence and augment antibiotic resistance. One community associated with negative healthcare outcomes consists of Pseudomonas aeruginosa and Staphylococcus aureus. When co-cultured, virulence factors secreted by P. aeruginosa reduce metabolism and growth in S. aureus. When grown in vitro, this allows P. aeruginosa to drive S. aureus toward extinction. However, when found in vivo, both species can co-exist. Previous work has noted that this may be due to altered gene expression or mutations. However, little is known about how the growth environment could influence the …

A Simple Method To Assess Porphyrin Basicity Using Competition Studies, Pranav Madadi, Ofek Gur, Ayush Desai

Undergraduate Student Symposium

Competition studies of three freebase porphyrins (H2OEP, H2OETPP, and H2TPP) were carried to assess their basicities. These porphyrins were selected because they are a good representation of natural occurring ones. In each experiment, the resultant UV-vis spectra were obtained by mixing and analyzing two porphyrins in a double-sided cuvette in which one was protonated using either trifluoroacetic acid (TFA) or hydrochloric acid (HCl) while the other was kept as a freebase. After mixing, the two porphyrins “compete” available protons, thus the most basic of them will acquire most of the protons. By adjusting the ratios of dications and freebases we …

A Search For A Solution To Antibiotic-Resistance: Uncovering Phage From Soil Samples That Bind To A Type Iii Secretion System Of Yersinia Pestis, Shruti Patel, Ritika Vonguru, Kenya Reid, Jewel Mousa, Megha Kurian

Undergraduate Student Symposium

The rise of antibiotic-resistant bacteria has recently become a major global health concern, requiring new methods to successfully combat these highly resistant microbes. One promising alternative to traditional antibiotics is phage therapy, where bacteriophages (viruses that infect bacteria) are utilized to target and kill bacteria. This study primarily focuses on discovering phages that are effective against Yersinia pestis (Y. pestis), the bacteria responsible for bubonic and pneumonic plague. One distinctive aspect of Y. pestis is its utilization of a type III secretion system (T3SS), a needle-like structure used to inject host cells with toxins that lead to infection. …
