In Defense Of Plants: Salicylic Acid In A Host-Parasite-Pathogen System, Timothy Kyle Martin
In Defense Of Plants: Salicylic Acid In A Host-Parasite-Pathogen System, Timothy Kyle Martin
Theses and Dissertations
Cuscuta pentagona is an obligate parasitic plant that uses a specialized organ, known as a haustorium, to penetrate host xylem and phloem to absorb water and nutrients from its hosts. As holoparasites, they lack chloroplast and therefore cannot photosynthesize. Bidirectional movement at the haustoria raises the possibility that the parasite can transmit defense signals from one host to another, though in what form is unclear. The biotrophic feeding mode, lack of chloroplast, and bidirectional movement across the haustoria lead me to hypothesize that (1) C. pentagona as a shoot parasite would elicit a systemic acquired resistance response in a host …
Intercropping Corn And Soybean: Profitability Of Different Agronomic Management Techniques, Raeann Lyn Huffman
Intercropping Corn And Soybean: Profitability Of Different Agronomic Management Techniques, Raeann Lyn Huffman
Theses and Dissertations
Intercropping is the practice of growing multiple crops together in the same field. This is not commonly implemented in Midwest agriculture - instead, current monoculture practices have garnered attention because of the negative environmental impacts of monoculture farming. For this study, corn and soybean were intercropped in a production agriculture setting to investigate the benefits to the producer and the environment. Intercropping corn and soybean crops may reduce the need for added nitrogen (N) fertilizer, saving money on inputs and potential loss of N from the farm to the environment. Soybeans within the system may utilize less of the soil …

Cachexia, or a loss of muscle mass, has been identified as a potential indicator of cancer survival rates. Previous explorations in research have connected muscular strength to muscle loss and cancer survivorship, but nationally generalizable findings are limited. PURPOSE: To investigate handgrip strength in cancer survivors using the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of US adults. METHODS: The analysis included 368 males and 425 females from the 2011-2014 NHANES dataset. Cancer survivor information (type of cancer and age of diagnosis) was determined by questionnaire. Cancer types were grouped into the following: skin cancers, reproductive …
The Correlation Between Ankle Proprioception And Lower Extremity Muscle Reactions In Response To Simulated Lateral Ankle Sprains, Erin M. Carroll
The Correlation Between Ankle Proprioception And Lower Extremity Muscle Reactions In Response To Simulated Lateral Ankle Sprains, Erin M. Carroll
Theses and Dissertations
Context: Lateral ankle sprains are one of the most commonly occurring sport-related injuries. The somatosensory system is primarily responsible for monitoring the position of the joints in space during movement. This system functions by way of neurological structures that provide proprioceptive and neuromuscular input to the brain. Motor control of the lower extremity relies on proprioceptive input to the central nervous system (CNS) and local neuromuscular control of each joint to produce coordinated, global muscular responses to external events. Previous research has investigated links between proprioception and neuromuscular control in relationship to ankle inversion separately, but none have searched for …
Sleep Quality And Prevalence Of Anxiety And Depression In Young Adults With Concussion History, Jessica Barrack
Sleep Quality And Prevalence Of Anxiety And Depression In Young Adults With Concussion History, Jessica Barrack
Theses and Dissertations
Background: Concussions are a growing public health concern, and emerging long-term health risks may negatively impact an individual’s quality of life. With concussions, there can be a multitude of signs and symptoms, but frequent long-term sequelae of concussions including mood disturbances (e.g. trait anxiety and depression) and sleep disturbances (e.g. difficulties initiating and maintaining sleep) are given less attention. Few clinicians address mood and sleep disturbances in their concussion assessment and management plan, potentially placing individuals at risk for prolonged disturbances beyond recovery. Purpose: To examine the relationship between sleep disturbances (sleep quality) and mood disturbances (trait anxiety and depression) …

Effects Of The Antidepressant Drug Vortioxetine On Ventral Pallidal Neuronal Activity, Respiration, And Heart Rate In The Rat, Piper Rogers
Effects Of The Antidepressant Drug Vortioxetine On Ventral Pallidal Neuronal Activity, Respiration, And Heart Rate In The Rat, Piper Rogers
Theses and Dissertations
Major Depressive Disorder (MDD) is a mental illness that affects millions of people worldwide. People diagnosed with MDD are often prescribed antidepressant drugs. Most antidepressants increase levels of serotonin (5-hydroxytryptamine, 5-HT) in the synapses between neurons. Selective-serotonin reuptake inhibitors (SSRIs), one class of antidepressants, do this by inhibiting the reuptake of serotonin released into the synapse. Serotonin neurons from the brainstem raphe nuclei affect a wide range of areas throughout the brain. Among these areas is the ventral pallidum (VP), located in the basal forebrain. Citalopram, an SSRI, has been found to increase the firing rate of action potentials of …

A Computational Investigation Of The Biophysical Mechanisms Underlying Thermotaxis In The Afd Neurons Of Caenorhabditis Elegans, Zachary Mobille
A Computational Investigation Of The Biophysical Mechanisms Underlying Thermotaxis In The Afd Neurons Of Caenorhabditis Elegans, Zachary Mobille
Theses and Dissertations
Thermotaxis in the nematode Caenorhabditis elegans (C. elegans) is studied at the cellular scale of the amphid finger-like ciliated (AFD) neurons, which have previously been shown to be essential for thermoreception. The voltage and calcium signals of AFD during temperature stimuli are described with ordinary differential equations. The primary calcium model is a modified version of that published by Kuramochi and Doi in 2017 to explain the calcium responses of the chemosensitive amphid single-ciliated right (ASER) neuron to fluctuations in extracellular salt concentration. To account for the effects of temperature, changes to the stimuli conditions under which inactivation takes place …
Effects Of Exercise Intensity And Type On Executive Function In Elementary-Aged Children, Patrick Pommier
Effects Of Exercise Intensity And Type On Executive Function In Elementary-Aged Children, Patrick Pommier
Theses and Dissertations
The interactions of exercise on executive functioning (EF) have been studied thoroughly in previous literature, focusing mostly on the interactions of aerobic exercise (AE) intensity and its effects on inhibition and working memory. Although multiple categories of EF have been shown to improve based on aerobic exercise, the foundation of brain development relies within its ability to utilize all three areas of EF simultaneously. Therefore, the purpose of this study was to determine the effects of exercise intensity and type of exercise (cognitive activation) on EF in elementary-aged children. Design: Eighteen children (mean age=10.4, SD=0.5, 61.1% girls) participated in a …

Evaluating The Multi-Level Community Effects Of Root Hemiparasites In Northern Illinois, Anna Marie Scheidel
Evaluating The Multi-Level Community Effects Of Root Hemiparasites In Northern Illinois, Anna Marie Scheidel
Theses and Dissertations
Root hemiparasites are green plants that tap into a neighboring plant’s water-filled xylem to acquire inorganic nutrients, which can lead to an accumulation of nutrients in hemiparasite biomass. I performed an observational field study at Nachusa Grasslands and Franklin Creek State Natural Area (Lee County, IL) in 2019 to investigate how the presence of five root hemiparasites (Aureolaria grandiflora (Benth.) Pennell, Agalinis tenuifolia (Vahl) Raf., Castilleja sessiliflora (Pursh), Dasistoma macrophylla (Nutt.) Raf., Pedicularis canadensis L.) affects their communities through the (a)keystone species hypothesis, that hemiparasites will increase measures of diversity by altering competition among surrounding plant species, (b) ecological engineer …

Physiological Consequences Of Neuromodulation And The Cellular Properties That Underlie Them, Margaret Louise Demaegd
Physiological Consequences Of Neuromodulation And The Cellular Properties That Underlie Them, Margaret Louise Demaegd
Theses and Dissertations
Neuronal activity is a product of more than the underlying neuronal connections. Modulatory influences like changes in the animal’s environment, the animals physiological state, or the release of neuromodulators can dramatically alter neuronal activity. Modulatory influences can be beneficial for the animal because they are a source of neuronal and behavioral plasticity, and they can provide neuronal circuits with the robustness needed to continue to function in new conditions, states, or tasks.However, malfunctions of the modulatory system can disrupt neuronal activity and lead to pathologies. Predicting how modulatory influences will alter neuronal activity is challenging because the underlying cellular and …
