Poststroke Seizure And Epilepsy: A Review Of Incidence, Risk Factors, Diagnosis, Pathophysiology, And Pharmacological Therapies, Joseph Phan, Mario Ramos, Theodore Soares, Mayur S. Parmar

HPD Articles

Stroke is the most common cause of epilepsy and ultimately leads to a decrease in the quality of life of those affected. Ischemic and hemorrhagic strokes can both lead to poststroke epilepsy (PSE). Significant risk factors for PSE include age less than 65 years, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), cortical involvement, and genetic factors such as TRPM6 polymorphism. The diagnosis of PSE is made by using imaging modalities, blood biomarkers, and prognostic criteria. Electroencephalography (EEG) is currently the gold standard to diagnose PSE, while new combinations of modalities are being tested to increase …

A Test Of Predator Avoidance By Larvae Of The Blue Ridge Two-Lined Salamander (Eurycea Wilderae) In Appalachian Streams, Taylor Hopkins, Emmeline Lombard, Carlos D. Camp

Georgia Journal of Science

Larval Blue Ridge Two-lined Salamanders (Eurycea wilderae) are significant components of Appalachian streams, reaching densities up to 100/m². Not surprisingly, these salamanders fall prey to many types of predator. In order to test the hypothesis that larval E. wilderae actively avoid predators, we paired them against a variety of predators of this species. Predators included Banded Sculpins (Cottus carolinae), Chattahoochee Crayfish (Cambarus howardi), and Spring Salamanders (Gyrinophilus porphyriticus), both adult and larval. We placed larvae in a 1-m metal trough filled with water with a predator placed in a cage …

Filling The Third Circle With Interdisciplinary Lesson Planning: A Case Study Of Pre-Service Teachers, Garrett Steede, Rebecca D. Swenson, Troy D. Mckay

Journal of Human Sciences and Extension

The three-circle model of agricultural education focuses on the importance of in-class instruction, supervised agricultural experiences, and FFA involvement. The agricultural communications career pathway is available to students through agricultural communications supervised agricultural experiences (SAE) programs and career development events within FFA. However, specific curriculum that teaches agricultural communications in the classroom is not readily available. The purpose of this qualitative case study was to examine the interdisciplinary lesson planning and integration process of pre-service teachers with focus on opportunities and limitations to teaching communication in the agriculture, food, and natural resources (AFNR) curriculum. In this case study, four pre-service …

Anthropology & Sociology Faculty Publications

Chimpanzees (Pan troglodytes) harbor rich assemblages of malaria parasites, including three species closely related to P. falciparum (sub-genus Laverania), the most malignant human malaria parasite. Here, we characterize the ecology and epidemiology of malaria infection in wild chimpanzee reservoirs. We used molecular assays to screen chimpanzee fecal samples, collected longitudinally and cross-sectionally from wild populations, for malaria parasite mitochondrial DNA. We found that chimpanzee malaria parasitism has an early age of onset and varies seasonally in prevalence. A subset of samples revealed Hepatocystis mitochondrial DNA, with phylogenetic analyses suggesting that Hepatocystis appears to cross species barriers more easily than Laverania. …

Master of Science in Integrative Biology Theses

My thesis covers the intricacies of ant microsculpture diversity, classification, evolution and function. To do this, the thesis is organized into two chapters. The first chapter is a review of ant cuticle and microsculpture diversity as well as including analyses examining the evolution and lability of microsculpture traits. I then review the literature for functional hypotheses related to ant microsculpture. The second chapter explores the relationship of microsculpture and important morphological, physiological, and ecological traits to evaluate support for functional hypotheses.

Investigation Into The Relationship Between Posture And Psychology: The Psychological Ramifications Of Forward Head And Rounded Shoulder Posture, Samuel Thomas Lauman

Kinesiology Dissertations - Archive

Embodied cognition speaks to the notion that the mind and body are inherently linked, and directly influence one another. Nonverbal communication experts hold the thought that sustaining chronic postures can impact an individual’s psychological disposition and vice versa. Therefore, the potential to intervene on these postures from a musculoskeletal rehabilitation perspective provides the opportunity to improve not only an individual’s posture, but also their psychological state. Forward head posture (FHP) and rounded shoulder posture (RSP) are common postural adaptations that occur from musculoskeletal dysfunction, and often lead to acute and chronic changes that can be a precursor to etiological pathologies. …

Using Community Science To Assess The Effect Of Wing Pattern And Weather On Butterfly Behavior, Abbigail Merrill

Animal Science Undergraduate Honors Theses

Signaling in insects is used as communication and for attraction of mates. The physical appearance of the insect as well as conditions such as weather can play a role in visual signaling, by influencing the wavelengths of light available, and subsequent signal detection. We do not know, however, whether signals butterflies present broadly correlate with how they behave. In this study, we looked at the wing patterns and behavior of butterflies in Northwest Arkansas over a 3.5-year period to assess the relationship between wing pattern, weather, and behavior. We used observational data collected by hundreds of University of Arkansas students …

Creating An Interdisciplinary Curriculum Within The Undergraduate Arts And Sciences Through Agar Art, Julie Torruellas Garcia, Kandy Lopez, Véronique Côté, Katie E. Crump

Biology Faculty Articles

Evidence-based studies on the benefits of integrating STEM into the arts are limited; however, some suggest that it can lead to improved scientific literacy and new approaches for artistic scholarship. Unfortunately, undergraduate education often creates disciplinary silos where the two are not integrated. Here, we discuss a unique collaboration between professors in the art and biology departments. Our goal was to integrate science into art courses using an agar art activity. We hypothesized that art students could effectively learn microbiology laboratory techniques and use them as novel tools for artistic practice. The activity was integrated into two to four sessions …

Poststroke Seizure And Epilepsy: A Review Of Incidence, Risk Factors, Diagnosis, Pathophysiology, And Pharmacological Therapies, Joseph Phan, Mario Ramos, Theodore Soares, Mayur S. Parmar

HPD Articles

Stroke is the most common cause of epilepsy and ultimately leads to a decrease in the quality of life of those affected. Ischemic and hemorrhagic strokes can both lead to poststroke epilepsy (PSE). Significant risk factors for PSE include age < 65age less than 65 years, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), cortical involvement, and genetic factors such as TRPM6 polymorphism. The diagnosis of PSE is made by using imaging modalities, blood biomarkers, and prognostic criteria. Electroencephalography (EEG) is currently the gold standard to diagnose PSE, while new combinations of modalities are being tested to increase diagnostic specificity. This literature review uncovers a newly found mechanism for the pathology of poststroke epilepsy. The pathogenesis of early-onset and late-onset is characterized by sequelae of neuronal cellular hypoxia and disruption of the blood-brain barrier, respectively. Interleukin-6 is responsible for increasing the activity of glial cells, causing gliosis and hyperexcitability of neurons. Epinephrine, high-mobility group protein B1, downregulation of CD32, and upregulation of HLA-DR impact the pathology of poststroke epilepsy by inhibiting the normal neuronal immune response. Decreased levels of neuropeptide Y, a neurotransmitter, act through multiple unique mechanisms, such as inhibiting intracellular Ca accumulation and acting as an anti-inflammatory, also implemented in the worsening progression of poststroke epilepsy. Additionally, CA1 hippocampal resonant neurons that increase theta oscillation are associated with poststroke epilepsy. Hypertensive small vessel disease may also have an implication in the temporal lobe epilepsy by causing occult microinfarctions. Furthermore, this review highlights the potential use of statins as primary prophylaxis against PSE, with multiple studies demonstrating a reduction in incidence using statins alone, statins in combination with antiepileptic drugs (AEDs), and statins with aspirin. The evidence strongly suggests that the second generation AEDs are a superior treatment method for PSE. Data from numerous studies demonstrate their relative lack of significant drug interactions, increased tolerability, and potential superiority in maintaining seizure-free status.

Creative Collaborations

The pandemic highlighted the anthropocentric nature of soundscapes, while the recent popularity of electric cars, quadcopters, and “noise cancellation” earbuds demonstrated how consumer products can rapidly change our awareness of sound. While light pollution is already extensively addressed in scholarly research, popular works such as The End of Night, and public engagement such as The International Dark Sky Association, the complex interplay of sound, natural resources, and public engagement is still emerging, particularly in creative fields.

Two UNLV scholars and artists are collaborating on this project: Julian Kilker, who specializes in visual and emerging technology research, and Tom Bjelic, who …

The Sweet Smell Of Mystery: The Scent Glands Of Oncopeltus Fasciatus, Despina Tsitlakidou

Wayne State University Theses

Scent glands (ScGs) are defensive glands that are found among a wide variety of insect orders. These glands represent a specialized function of the exocrine system; however, the developmental mechanism remains unclear. Previous functional studies of the endocrine glands revealed that the endocrine and tracheal systems utilize similar genetic regulatory networks which indicate that these systems have common primordia. In Drosophila, sal is localized in the prothoracic gland while in Oncopeltus the gene is localized in the duct cells of the abdominal scent glands (Hanna & Popadić, 2020; Sánchez-Higueras et al., 2014). RNAi mediated knockdown of sal resulted in significant …

Investigating The Behavioral And Social Context Of Sound In The Surface Foraging Strategies Of Humpback Whales (Megaptera Novaeangliae), Sarah Weiss

Theses - ALL

Humpback whales are known for the plastic and variable nature of their acoustic communication, social interactions, and foraging behaviors. Distinct foraging strategies are used to capture different prey types at the surface and on the seafloor. Sounds produced during foraging are thought to facilitate intraspecific social communication. Previous studies have identified specific sound types produced by humpbacks associated exclusively with benthic foraging strategies, suggesting functions related to foraging behavior. In this study, we use suction cup acoustic tags (DTAGs) deployed on humpbacks in the western North Atlantic from 2006-2009 to investigate the social sound production associated with surface foraging ecology, …

Insight Into The Evolution Of Anuran Foot Flag Displays: A Comparative Study Of Color And Kinematics, Nigel K. Anderson, K. V. Gururaja, Lisa A. Mangiamele, Erin C. Netoskie, Sarah Smith, Matthew J. Fuxjager, Doris Preininger

Biological Sciences: Faculty Publications

Understanding how complex animal displays evolve is a major goal of evolutionary organismal biology. Here, we study this topic by comparing convergently evolved gestural displays in two unrelated species of frog (Bornean Rock Frog, Staurois parvus, and Kottigehara Dancing Frog, Micrixalus kottigeharensis). This behavior, known as a foot flag, is produced when a male ?waves' his hindlimb at another male during bouts of competition for access to mates. We assess patterns of variation in the color of frog feet and the kinematics of the display itself to help pinpoint similarities and differences of the visual signal elements. We find clear …

Pilot Development Of A Critical Food Safety Message Visual Communication Tool For Farmers’ Market Vendors, Lilly W. Jan, Shannon M. Coleman, Anirudh Naig

Journal of Human Sciences and Extension

Farmers’ markets are popular sources of fresh and ready-to-eat foods for consumers in the United States. However, research indicates that food safety practices of vendors and their employees serve as a concern for customers. This pilot study focused on assessing a visual-based, minimal-text educational tool that was disseminated to farmers’ market vendors and employees (n = 27) in Iowa. The tool was evaluated using a post-intervention survey of vendors’ and employees’ knowledge of food safety practices and their attitudes towards the educational tool. The results did not show a statistically significant increase in attitude and knowledge scores of farmers’ market …

Too Little Ph: How Freshwater Acidification Impacts The Abundance Of Macrophytes Consumed By Rusty Crayfish, Lauren Tucker, Paul Moore Dr., Jay Jones Mr.

Honors Projects

Anthropogenic activities such as the burning of fossil fuels result in increased atmospheric carbon dioxide (CO₂) concentration. High levels of atmospheric CO₂ cause chemical shifts in the carbon cycle. Changes in the carbon cycle due to increased CO₂ levels lead to ocean and freshwater acidification. Freshwater acidification is problematic for species that synthesize their own shells as well as species that use olfaction for decision-making. Rusty crayfish (Faxonius rusticus) were subject to simulated freshwater acidification and fed two types of macrophyte, Chara (Chara braunii) and Myriopyllum (Myriophyllum sibiricum). A series …

Resrouce Allocation And Visual Communication In Lepidoptera, Linda Nicole Fipps

Theses and Dissertations

Visual signals in the form of wing color, size, shape, pattern, and UV reflectance play an important role in the mating and reproductive strategies of diurnal butterflies. Wing-based visual signals are linked to different functions and can be acted on by a variety of selective pressures. In a comprehensive look at the literature on the visual communication strategies of lepidopteran species, I look at how visual signals, most notably color, are used, generated, and perceived. I discuss the costs and benefits of those strategies for the fitness of butterflies and moths and look at lepidopteran visual communication through the lens …

The Multifunctional Roles Of Polyphenols In Plant-Herbivore Interactions, Sukhman Singh, Ishveen Kaur, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

There is no argument to the fact that insect herbivores cause significant losses to plant productivity in both natural and agricultural ecosystems. To counter this continuous onslaught, plants have evolved a suite of direct and indirect, constitutive and induced, chemical and physical defenses, and secondary metabolites are a key group that facilitates these defenses. Polyphenols—widely distributed in flowering plants—are the major group of such biologically active secondary metabolites. Recent advances in analytical chemistry and metabolomics have provided an opportunity to dig deep into extraction and quantification of plant-based natural products with insecticidal/insect deterrent activity, a potential sustainable pest management strategy. …

Hurricane Irma Induces Divergent Behavioral And Hormonal Impacts On An Urban And Forest Population Of Invasive Anolis Lizards: Evidence For An Urban Resilience Hypothesis, Haralambos Fokidis, Taylor Brock

Faculty Publications

Hurricanes can have both profound short-term effects on animal populations and serve as long-term drivers of evolutionary change. Animals inhabiting varying habitats may differ in their response to hurricane impacts. Increasing evidence sug- gests that animals from urban areas exhibit different behavioral and physiological traits compared to rural counterparts, in- cluding attenuated hormonal stress responses and a lowered propensity for flight behavior. A unique opportunity was pre- sented when Hurricane Irma hit Florida on 10 September 2017 and interrupted a study of invasive brown anoles (Anolis sagrei) at an urban and a forest. Using data collected before and after Hurricane …

Investigation Of Fluorescence In Selected Mammals Of Arkansas, C. Renn Tumlison, Terry L. Tumlison

Journal of the Arkansas Academy of Science

The adaptive value of fluorescence among the vertebrates has been studied most in fishes and birds, and only a few observations have been published regarding fluorescence in the pelage of mammals. Recently, reports of fluorescence in some marsupials, the platypus, and in flying squirrels have become available. We report the occurrence of fluorescent properties in some mammals from Arkansas. Most carnivores, bats, and rodents did not exhibit the property when viewed under UV light. However, opossums, rabbits, a weasel, muskrats, and moles showed substantial UV response, and a few other mammals showed minor fluorescence. Colors fluoresced included pink, green, and …
