The triple network model provides a common framework for understanding affective and neurocognitive dysfunctions across multiple disorders, including central executive network (CEN), default mode network (DMN), and salience network (SN). Considering the effect of traumatic experience on post-traumatic stress disorder (PTSD), this study aims to explore the alteration of triple network connectivity in a specific PTSD induced by a single prolonged trauma exposure. With an arterial spin labeling sequence, three networks were first identified using independent component analysis among 10 PTSD patients and 10 healthy survivors, who experienced the same coal mining flood disaster. Then, the triple network connectivity was …

Understanding speech in noisy environments can be difficult, especially for people with hearing loss. The background noise can cover up the sounds of interest. Normally, the auditory system works to alleviate this problem by tagging and then cancelling the noise. Our experiments are aimed at understanding the mechanism of this noise cancellation process. We hypothesize that non-linear signal processing in the mammalian cochlea (the most peripheral part of the auditory system) is the basis of noise cancellation. To test this hypothesis, we measured the responses of auditory-nerve fibers (ANFs) to sounds embedded in background noise with different statistical properties. ANFs …

Removal Of Endocrine Disrupting Compounds Using Membrane Bioreactor, Mohanad Ali Abdulsahib Kamaz
Graduate Theses and Dissertations
The presence of endocrine disrupting compounds (EDCs) and pharmaceutically active compounds (PhAC) such as pesticides, personal care products, antibiotics and pharmaceutical compounds, in sewage, industrial, and domestic waters has extensively become the major concern for health and environmental organizations. These compounds have the ability to interact with mammalian endocrine system and disrupting their functions. The traditional activated sludge processes are designed to degrade solids, organic carbon and nitrogen loading. Although several treatment steps in a wastewater treatment plant can contribute to partial removal of EDCs, effective removal has been a challenge due to their resistant chemical and biological degradation and …

Examination Of The Impact Of Condensed Biofeedback Training On Acute Stress Responses, Meredith Carroll, Brent Winslow
Aeronautics Faculty Publications
The objective of this study was to measure the effects of a condensed 90 minute Biofeedback Training (BFT) method on stress response and decision making performance under stress. Forty one novice male participants received either BFT training, which incorporated diaphragmatic breathing with Stress Inoculation Training (SIT), or a control training task. Participants completed pre- and post-training assessments which incorporated a socio evaluative stress induction method followed immediately by performance of a simulation- based decision making under stress scenario. Stress was assessed using real-time physiological measures of the Autonomic Nervous System (ANS) response and cortisol measures of the Hypothalamic-Pituitary-Adrenal (HPA) axis …

: Cold atmospheric plasma (CAP) treatment is a rapidly expanding and emerging technology for cancer treatment. Direct CAP jet irradiation is limited to the skin and it can also be invoked as a supplement therapy during surgery as it only causes cell death in the upper three to five cell layers. However, the current cannulas from which the plasma emanates are too large for intracranial applications. To enhance efficiency and expand the applicability of the CAP method for brain tumors and reduce the gas flow rate and size of the plasma jet, a novel micro-sized CAP device (µCAP) was developed …
Role Of Trpv4 In Astrocyte Extracellular Matrix Production, Abby Terlouw
Role Of Trpv4 In Astrocyte Extracellular Matrix Production, Abby Terlouw
Biomedical Engineering Undergraduate Honors Theses
Traumatic Brain Injury (TBI) is an alteration of brain pathology following damage of the central nervous system (CNS) by an external force. In the CNS, glial scar formation often occurs following TBI, and astrocytes are widely believed to contribute to this scar formation. While the role of astrocytes in extracellular matrix (ECM) production is known, the exact mechanism(s) for this event remain unclear. One possible method is the activation of transient receptor potential vanilloid 4 (TRPV4). TRPV4 is a channel protein found in the astrocyte membrane which has been shown to generate intracellular calcium ions following mechanical stimulation. Previous research …

Objective. Blood flow is one such available observable promoting a wealth of physiological insight both individually and in combination with other metrics.
Approach. Near-infrared diffuse correlation spectroscopy (DCS) and, to a lesser extent, diffuse correlation tomography (DCT), have increasingly received interest over the past decade as noninvasive methods for tissue blood flow measurements and imaging. DCS/DCT offers several attractive features for tissue blood flow measurements/imaging such as noninvasiveness, portability, high temporal resolution, and relatively large penetration depth (up to several centimeters).
Main results. This review first introduces the basic principle and instrumentation of DCS/DCT, followed by presenting …

The problem this study addresses is the uncertainty of the common circumstances that general aviation pilots find themselves in that create a hypoxic state, as well as whether or not that pilot reported the occurrence to the proper establishments. The results of this study showed not only those that were impacted the greatest by hypoxia, but also a caring concern for reporting these events. The key elements for this research were:
• Level of flying experience that encountered hypoxia
• Reporting statistics
• Reasons for not reporting the event
• Suggestions for bettering flight physiology training

Background: Left ventricular (LV) torsion is an important indicator of cardiac function that is limited by high inter-test variability (50% of the mean value). We hypothesized that this high inter-test variability is partly due to inconsistent breath-hold positions during serial image acquisitions, which could be significantly improved by using a respiratory navigator for cardiovascular magnetic resonance (CMR) based quantification of LV torsion.
Methods: We assessed respiratory-related variability in measured LV torsion with two distinct experimental protocols. First, 17 volunteers were recruited for CMR with cine displacement encoding with stimulated echoes (DENSE) in which a respiratory navigator was used to measure …

Cells are often subjected to the effect of reactive oxygen species (ROS) as a result of both intracellular metabolism and exposure to exogenous factors. ROS-dependent oxidative stress can induce 8-oxodG within the GGG triplet found in the G-rich human telomeric sequence (TTAGGG), making telomeres highly susceptible to ROS-induced oxidative damage. Telomeres are nucleoprotein complexes that protect the ends of linear chromosomes and their dysfunction is believed to affect a wide range of cellular and/or organismal processes. Acute oxidative stress was shown to affect telomere integrity, but how prolonged low level oxidative stress, which may be more physiologically relevant, affects telomeres …

The Effects Of Adaptogens On The Physical And Psychological Symptoms Of Chronic Stress, Tosin O. Ajala
DISCOVERY: Georgia State Honors College Undergraduate Research Journal
Stress is a state of disharmony or threatened homeostasis. The maintenance of homeostasis in stages of internal or external challenges, called stressors, requires constant adjustments of hormonal, behavioral, and autonomic functions. The nuances of life may bring about unwanted stress to the human body. Some of the top causes of stress in America include work, finances, relationships, and health. There are numerous physical and psychological symptoms associated with long-term “chronic” stress, which include chronic fatigue, frustration, irritability, insomnia, frequent headaches, chest and back pain, weakness, and weight gain or weight loss. These symptoms of chronic stress are associated with depression, …
