A number of studies have focused on the role of specific brain regions, such as the dorsal anterior cingulate cortex during trials on which participants make errors, whereas others have implicated a host of more widely distributed regions in the human brain. Previous work has proposed that there are multiple cognitive control networks, raising the question of whether error-related activity can be found in each of these networks. Thus, to examine error-related activity broadly, we conducted a meta-analysis consisting of 12 tasks that included both error and correct trials. These tasks varied by stimulus input (visual, auditory), response output (button …


Attitudes Towards An Evidence-Based Clinical Decision Support Tool To Reduce Exposure To Ionizing Radiation, Raymond Zakhari 2015 Liberty University

Attitudes Towards An Evidence-Based Clinical Decision Support Tool To Reduce Exposure To Ionizing Radiation, Raymond Zakhari

Faculty Publications and Presentations

Patients who suffer minor brain injuries experience unnecessary ionizing radiation in the form of a non-contrast head CT scan despite the dearth of evidence supporting standard CT scans for all brain injuries. Exposure to ionizing radiation increases the incidence of certain types of cancer. This evidence-based practice change project assesses the attitude of clinicians towards evidence-based clinical decision support tools, specifically the Canadian CT head rule. The use of highly sensitive clinical decision support tools is supported in the literature to help healthcare providers mitigate the risk associated with unnecessary use of CT scan imaging studies. The project was conducted …


Enabling Real-Time Ultrasound Imaging Of Soft Tissue Mechanical Properties By Simplification Of The Shear Wave Motion Equation, Aaron J. Engel, Gregory R. Bashford 2015 University of Nebraska-Lincoln

Enabling Real-Time Ultrasound Imaging Of Soft Tissue Mechanical Properties By Simplification Of The Shear Wave Motion Equation, Aaron J. Engel, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Ultrasound based shear wave elastography (SWE) is a technique used for non-invasive characterization and imaging of soft tissue mechanical properties. Robust estimation of shear wave propagation speed is essential for imaging of soft tissue mechanical properties. In this study we propose to estimate shear wave speed by inversion of the firstorder wave equation following directional filtering. This approach relies on estimation of first-order derivatives which allows for accurate estimations using smaller smoothing filters than when estimating second-order derivatives. The performance was compared to three current methods used to estimate shear wave propagation speed: direct inversion of the wave equation (DIWE), …

Emergency Department Ultrasound Probe Infection Control: Challenges And Solutions, Hamid A. Shokoohi, Paige Armstrong, Ryan Tansek

Emergency Medicine Faculty Publications

Point-of-care ultrasound (US) has become a cornerstone in the diagnosis and treatment of patients in the emergency department (ED). Despite the beneficial impact on patient care, concern exists over repeat use of probes and the role as a vector for pathogen transmission. US probes are used for various applications, with the level of infection risk, based on the Spaulding Classification, ranging from noncritical with common practice to semicritical with endocavitary probes. To date, the most closely studied organisms are Staphylococcus aureus and human papilloma virus. Current evidence does confirm probe colonization but has not established a causative role in human …

Which Methods Of Treating Attention Deficit Hyperactive Disorder Are Most Effective And Most Closely Match Patient Lifestyle?, Yehudit Erlbaum 2015 Touro College

Which Methods Of Treating Attention Deficit Hyperactive Disorder Are Most Effective And Most Closely Match Patient Lifestyle?, Yehudit Erlbaum

The Science Journal of the Lander College of Arts and Sciences

ADHD, attention deficit hyperactive disorder, is a disorder characterized by hyperactivity, inattentiveness, inability to remain on task, fidgetiness, and impulsivity. An over absorption of dopamine by the dopamine transporters leads to a lack of dopamine, the inhibiting neurotransmitter in the brain, resulting in the inability for the individual to inhibit their impulses. The disease is most likely seen in children but may continue into adulthood. The length of the disease across the individual’s life span, results in expensive treatment, whether it be medication or Cognitive Behavior Therapy, CBT. Therefore, these medical costs have caused researchers to find the most efficient …

Background

Chronic pain is common in children and adolescents and is often associated with severe functional disability and mood disorders. The pharmacological treatment of chronic pain in children and adolescents can be challenging, ineffective, and is mostly based on expert opinions and consensus. Ketamine, an N-methyl-D-aspartate receptor antagonist, has been used as an adjuvant for treatment of adult chronic pain and has been shown, in some instances, to improve pain and decrease opioid-requirement. We examined the effects of subanesthetic ketamine infusions on pain intensity and opioid use in children and adolescents with chronic pain syndromes treated in an outpatient setting. …

ATP-binding cassette subfamily G member 2 (ABCG2) is a member of the ABC transporter superfamily proteins, which has been implicated in the development of multidrug resistance (MDR) in cancer, apart from its physiological role to remove toxic substances out of the cells. The diverse range of substrates of ABCG2 includes many antineoplastic agents such as topotecan, doxorubicin and mitoxantrone. ABCG2 expression has been reported to be significantly increased in some solid tumors and hematologic malignancies, correlated to poor clinical outcomes. In addition, ABCG2 expression is a distinguishing feature of cancer stem cells, whereby this membrane transporter facilitates resistance to the …

Research Round-Up: Manual Muscle Testing, Mary Insana Fisher, Shana Harrington 2015 University of Dayton

Research Round-Up: Manual Muscle Testing, Mary Insana Fisher, Shana Harrington

Physical Therapy Faculty Publications

Manual muscle testing was developed in response to the need to assess muscle strength losses during the polio outbreak in early part of the 20th century. The development of this original method is credited to Wilhelmine Wright and Robert W. Lovett, MD. Wright presented this method in 1912 in the Boston Medical Surgical Journal, and Lovett expanded the description of the testing method in 1916 in the Journal of the American Medical Association. The development of quantifying muscle strength by rating force generated against external resistance was an important development in objectifying assessment methods of the time.

Today, manual muscle …


Ethical Perspectives Of Direct-To-Consumer Genetic Testing, Pawan Acharya, Rupesh Gautam 2015 University of Southern Denmark, Denmark

Ethical Perspectives Of Direct-To-Consumer Genetic Testing, Pawan Acharya, Rupesh Gautam

Journal of Health Ethics

Direct-to-consumer (DTC) genetic testing, which evolved from genomics is not free from controversies and ethical dilemmas. Conduction of genetic testing without direct communication between the users and certified medical professionals has aroused many ethical concerns. We discuss some ethical dilemmas surrounding DTC genetic testing in terms of quality assurance of the test, information communication process of the result, confidentiality of test result and the right to privacy, cost and price regulations, and user safety and harm mitigation. DTC genetic testing lies in the middle of a clash between liberal trade policies and state’s regulations as a case of extreme paternalism. …

Genome Engineering To Create Dominant Alleles In Caenorhabditis Elegans Using Crispr-Cas9 Technology, Abrar Sulaimani

Graduate School of Biomedical Sciences Theses and Dissertations

Many investigators have being using CRISPR-Cas9 as a method of genome engineering because it is easy, accurate and fast. This technique has been used to modify the genomes of a wide variety of organisms, including the nematode Caenorhabditis elegans (C. elegans). The short life cycle and ease of introducing exogenous plasmids make C. elegans an ideal system for advancing this technique. My thesis had two aims that focused on developing methods to create dominant alleles in C. elegans. Genetic modifications like precise deletion and insertions into a locus of chromosome are technically challenging. Additionally, although there are several ways of …

The Need For Theory To Guide Concussion Research, Dennis Molfese 2015 University of Nebraska-Lincoln

The Need For Theory To Guide Concussion Research, Dennis Molfese

Center for Brain, Biology, and Behavior: Faculty Publications

While the focus on concussion research has expanded greatly over the past decade, progress in identifying the mechanisms and consequences of head injury, the recovery path and the development of potential interventions to facilitate recovery have been largely absent. Instead, the field has largely progressed through an accumulation of data without the guidance of any systematic theory to guide the formulation of research questions or generate testable hypotheses. As part of this special issue on sports concussion, we advance a theory to describe the evolution of a neural network during the development of a cognitive process as well as the …

Department of Psychology: Faculty Publications

Although no data exist, general practice recommends only rest following concussion. This randomized clinical trial found that programmed physical exertion during recovery produced no significant differences in recovery time between groups of participants. However, high levels of exertion were deleterious. This study provides initial evidence that moderate physical activity is a safe replacement behavior during recovery.

Objective: Changes in food-cue neural reactivity associated with behavioral and surgical weight loss interventions have been reported. Resting functional connectivity represents tonic neural activity that may contribute to weight loss success. This study explores whether intervention type is associated with differences in functional connectivity after weight loss. Methods: Fifteen participants with obesity were recruited prior to adjustable gastric banding surgery. Thirteen demographically matched participants with obesity were selected from a separate behavioral diet intervention. Resting-state functional magnetic resonance imaging was collected 3 months after surgery/ behavioral intervention. ANOVA was used to examine post-weight loss differences between the two groups in …

In this study we examined differences in fMRI activation and deactivation patterns during episodic verbal memory encoding between individuals with MCI (n = 18) and healthy controls (HCs) (n = 17). Participants were scanned in two different sessions during the application of self-initiated or directed instructions to apply semantic strategies at encoding of word lists. MCI participants showed reduced free recall scores when using self-initiated encoding strategies that were increased to baseline controls' level after directed instructions were provided. During directed strategic encoding, greater recruitment of frontoparietal regions was observed in both MCI and control groups; group differences …
