Comparison Of Hippocampal Interleukin-6 Immunoreactivity After Exhaustive Exercise In Both Exercise-Trained And Untrained Rats, Lati̇fe Arzu Aral, Lamia Pinar, Güleser Göktaş, Elçi̇n Yaşar Deveden, Deni̇z Erdoğan

Turkish Journal of Medical Sciences

Exhaustive exercise is a strong stress factor and can impact cytokine production in the brain. Interleukin-6 (IL-6) is produced in greater amounts than any other cytokine in response to exercise, and its effects are closely related to both exercise duration and intensity. In this study, we measured the differences between the amount of IL-6 reactivity of the hippocampus after an exhaustive session of running in long-term exercise-trained and untrained rats. Materials and methods: The exercise-trained group ran on a treadmill for 12 weeks. Both groups were forced to run until exhaustion. Each group of rats was sacrificed immediately, 1 day, …

School of Veterinary and Biomedical Sciences: Faculty Publications

The genus Macavirus of the subfamily Gammaherpesvirinae includes viruses that infect lymphoid cells of domestic and wild ruminants and swine, causing asymptomatic latent infections in reservoir hosts. Here, we describe the genome of bovine herpesvirus 6 (BoHV-6), a

macavirus ubiquitous in healthy cattle populations. The BoHV-6 genome exhibited architecture conserved in macaviruses, including a repetitive H-DNA region and unique, 141 kilobase pair L

DNA region predicted to encode 77 genes. BoHV-6 encoded in variable genomic regions a novel complement of genes relative to other characterized macaviruses, likely contributing to distinctive aspects of BoHV-6 infection biology and host range. Most notably, …

An Evolutionary Perspective On Infectious And Chronic Disease, John Eberth

Theses and Dissertations

The integration of evolutionary biology with traditional medicine can elucidate novel mechanisms of contemporary disease. Whereas the goal of traditional medicine is to treat and cure the proximate causes, evolutionary biology aims to understand the driving forces behind why humans are susceptible to disease. To form the basis of this hypothesis we postulate that modern man's current genetic information was programmed at a time, and in an environment, that is not relevant to today's human populations. The discordance between these genes of our ancestors and the environment of contemporary humans is thought to be a major reason for the increase …

The Role Of Microrna In Staphylococcal Enterotoxin B-Induced Inflammation And Acute Lung Injury, Roshni Rao

Theses and Dissertations

Staphylococcal enterotoxin B (SEB) is a potent activator of the Vβ8+T-cells leading to the proliferation of nearly 30% of the T-cell pool. As a consequence, excessive amounts of cytokine mediators are released leading to extensive tissue damage and sometimes toxic shock and death. Due to the ease with which SEB can be aerosolized anddisseminated, it is considered a biological weapon. In the current study, we investigated the pro-inflammatory effects of SEB in two mouse models of acute inflammatory lung injury. Specifically, while inflammatory cues are known to elicit changes in key transcriptional factors and gene expression, we explored for the …

The Effect Of Gaba A Antagonism On Locomotor Activity And Dopamine Release In The Mouse Caudate Putamen Following Acute Toluene Inhalation: An In-Vivo Microdialysis Study, Sean Callan

Wayne State University Theses

Toluene is ubiquitous solvent commonly inhaled recreationally. Despite its frequency of misuse, there is little understanding of how toluene acts within the brain. To examine this, this master's thesis examined the impact of acutely inhaled toluene on dopamine (DA) release in the mouse CPu in vivo using microdialysis techniques. Toluene inhalation produced dose-dependent increases in DA levels as well as changes in locomotor activity. These effects were potentiated by pre-treatment with the GABAA antagonist bicuculline via reverse microdialysis delivery. These results suggest that the DA dynamics of toluene abuse are related to toluene's previously explored effects on the GABA system. …

Effects Of Hyperbaric Oxygen On Eye Tracking Abnormalities In Males After Mild Traumatic Brain Injury, Joanna R. Wares, David X. Cifu, Kathy W. Hoke, Paul A. Wetzel, George Gitchel, William Carne

Department of Math & Statistics Faculty Publications

The effects of hyperbaric oxygen (HBO2) on eye movement abnormalities in 60 military servicemembers with at least one mild traumatic brain injury (mTBI) from combat were examined in a single-center, randomized, double-blind, sham-controlled, prospective study at the Naval Medicine Operational Training Center. During the 10 wk of the study, each subject was delivered a series of 40, once a day, hyperbaric chamber compressions at a pressure of 2.0 atmospheres absolute (ATA). At each session, subjects breathed one of three preassigned oxygen fractions (10.5%, 75%, or 100%) for 1 h, resulting in an oxygen exposure equivalent to breathing either surface air, …

Neural Plasticity Following Ischemia, Shira Brickman

The Science Journal of the Lander College of Arts and Sciences

Neural plasticity refers to the ability of one’s brain to change its structure and/or function in response to changes in behavior, environment, and neural processes. When a person suffers an ischemic brain injury, it often leads to hemisyndrome with motor and sensory deficits in the arm, leg, and face of one side. This article discusses the various ways that the existing network can be restructured and neuronal connections can be remodeled after the injury to enable partial or complete recovery of motor function. Spontaneous functional recovery after stroke develops through the overlapping sequence of events including a phase of axonal …

Preparation, Characterization, And Delivery Of Antibodies Binding To A Model Oncogenic Rna, Human Initiator Trna, Jennifer Archer

Electronic Theses and Dissertations

Non-coding RNAs (ncRNAs) account for a higher percent of the genome than coding mRNAs, and are implicated in human disease such as cancer, neurological, cardiac and many others. While the majority of ncRNAs involved in disease were originally attributed to a class of RNAs called micro RNAs (miRNAs) with a small size of only about 19 -24 base pairs, emerging research has now demonstrated a class of long non-coding RNAs (lncRNAs) that have a size of over 200 base pairs to be responsible for gene regulation and other functional roles and have also found to contribute to pathogenesis in humans. …

Host And Bacterial Determinants Of Staphylococcus Aureus Nasal Colonization In Humans, Gowrishankar Muthukrishnan

Electronic Theses and Dissertations

Staphylococcus aureus (SA), an opportunistic pathogen colonizing the anterior nares in approximately 30% of the human population, causes severe hospital-associated and community-acquired infections. SA nasal carriage plays a critical role in the pathogenesis of staphylococcal infections and SA eradication from the nares has proven to be effective in reducing endogenous infections. To understand SA nasal colonization and its relation with consequent disease, assessment of nasal carriage dynamics among a diverse population and determining factors responsible for SA nasal carriage have become major imperatives. Here, we report on an extensive longitudinal monitoring of SA nasal carriage in 109 healthy individuals over …
