Enhanced Control Of Dorsolateral Prefrontal Cortex Neurophysiology With Real-Time Functional Magnetic Resonance Imaging (Rt-Fmri) Neurofeedback Training And Working Memory Practice, Matthew Sherwood, Jessica Kane, Michael Patrick Weisend, Jason G. Parker

Wright State Research Institute Publications

Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback can be used to train localized, conscious regulation of blood oxygen level-dependent (BOLD) signals. As a therapeutic technique, rt-fMRI neurofeedback reduces the symptoms of a variety of neurologic disorders. To date, few studies have investigated the use of self-regulation training using rt-fMRI neurofeedback to enhance cognitive performance. This work investigates the utility of rt-fMRI neurofeedback as a tool to enhance human cognition by training healthy individuals to consciously control activity in the left dorsolateral prefrontal cortex (DLPFC). A cohort of 18 healthy participants in the experimental group underwent rt-fMRI neurofeedback from the left …

Complex Acylation Of Angiotensin Ii By N-Hydroxysulfosuccinimide Linked Biotin Reagents, Q. Liu, A. Lam, A. Kathuria

Pharmaceutical Sciences

N-Hydroxysulfosuccinimide-linked biotins (sulfoNHS-biotins) are water soluble biotin tags commonly used to conjugate a biotin moiety to proteins by rapid N-acylation of primary amines. Unexpected O-acylation by sulfoNHSbiotin on tyrosine of Angiotensin II (Ag-II) and an acylation on third site unable to characterize were identified by LC-MS in addition to the expected N-acylation on the N-terminal of Ag-II. The N-acylation only undergoes incomplete hydrolysis in 0.1% formic acid not at pH 7.2 and 8.0, while two unexpected acylation hydrolyze at both conditions, but their hydrolysis in 0.1% formic acid was much more rapid. Dithiothreitol treatment selectively catalyzed hydrolysis of both of …

Dignity, Pet-Euthanasia And Person Euthanasia, Thomas A. Cavanaugh

Philosophy

Challenging the standard argument for euthanasia, G. E. M. Anscombe holds that euthanasia does not comport with human dignity interpreted in terms of self-determination. For, were self-determination to ground any killing it would justify self-killing, not being killed by another. I articulate reasons for thinking that she correctly identifies the dissonance of self-determination with euthanasia. Additionally, I argue that the same holds, less obviously, for physician-assisted suicide (PAS, which she does not explicitly consider).

Moreover, Anscombe suggests that what actually occurs in euthanasia in effect equates a person to a humanely euthanized dog and, thereby, trivializes and degrades human lives …

The Effect Of Arm Position On Lower Extremity Kinematics During A Single Limb Drop Landing: A Preliminary Study, C. Masters, J. Johnstone, Gerwyn Hughes

Kinesiology (Formerly Exercise and Sport Science)

Anterior cruciate ligament (ACL) injuries occur most commonly during non-contact situations, such as landing from a jump. Arm position has been shown to affect the loading of the lower extremity and therefore alter the potential injury risk. This study aimed to investigate the effect of arm position on lower extremity kinematics during single limb drop landings. Eight recreational American football players performed single limb drop landings on their preferential limb in four different conditions; (1) control (arms free); (2) arms to landing limb side; (3) arms in front of body; and (4) arms away from landing limb side. Kinematics of …

The Effect Of Repetitive Ankle Perturbations On Muscle Reaction Time And Muscle Activity, Peter K. Thain, Andrew C.S. Mitchell, Gerwyn Hughes

Kinesiology (Formerly Exercise and Sport Science)

The use of a tilt platform to simulate a lateral ankle sprain and record muscle reaction time is a well-established procedure. However, a potential caveat is that repetitive ankle perturbation may cause a natural attenuation of the reflex latency and amplitude. This is an important area to investigate as many researchers examine the effect of an intervention on muscle reaction time. Muscle reaction time, peak and average amplitude of the peroneus longus and tibialis anterior in response to a simulated lateral ankle sprain (combined inversion and plantarflexion movement) were calculated in twenty-two physically active participants. The 40 perturbations were divided …

A Global Meta-Analysis Of Forest Bioenergy Greenhouse Gas Emission Accounting Studies, T Buchholz, M D. Hurteau, J Gunn, David Saah

Environmental Science

The potential greenhouse gas benefits of displacing fossil energy with biofuels are driving policy development in the absence of complete information. The potential carbon neutrality of forest biomass is a source of considerable scientific debate because of the complexity of dynamic forest ecosystems, varied feedstock types, and multiple energy production pathways. The lack of scientific consensus leaves decision makers struggling with contradicting technical advice. Analyzing previously published studies, our goal was to identify and prioritize those attributes of bioenergy greenhouse gas (GHG) emissions analysis that are most influential on length of carbon payback period. We investigated outcomes of 59 previously …

Metabolism And Metabolic Inhibition Of Xanthotoxol In Human Liver Microsomes, Zhongnv Ma, Xianbao Shi, Gang Zhang, Feng Guo, Lina Shan, Jiqun Cai

Medicinal Chemistry Publications

Cytochrome p450 (CYP450) enzymes are predominantly involved in Phase I metabolism of xenobiotics. In this study, the CYP450 isoforms involved in xanthotoxol metabolism were identified using recombinant CYP450s. In addition, the inhibitory effects of xanthotoxol on eight CYP450 isoforms and its pharmacokinetic parameters were determined using human liver microsomes. CYP1A2, one of CYP450s, played a key role in the metabolism of xanthotoxol compared to other CYP450s. Xanthotoxol showed stronger inhibition on CYP3A4 and CYP1A2 compared to other isoenzymes with the IC50 of 7.43 μM for CYP3A4 and 27.82 μM for CYP1A2. The values of inhibition kinetic parameters (Ki) were 21.15 …

Repeated Low-Dose Organophosphate Dfp Exposure Leads To The Development Of Depression And Cognitive Impairment In A Rat Model Of Gulf War Illness, Laxmikant Deshpande, Kristin Phillips

Neurology Publications

Approximately 175,000 to 250,000 of the returning veterans from the 1991 Persian Gulf War exhibit chronic multi-symptom illnesses that includes neurologic co-morbidities such as depression, anxiety and cognitive impairments. Amongst a host of causative factors, exposure to low levels of the nerve agent Sarin has been strongly implicated for expression of Gulf War Illness (GWI). Nerve agents similar to pesticides are organophosphate (OP) compounds. There is evidence from civilian population that exposure to OPs such as in agricultural workers and nerve agents such as the survivors and first-responders of the Tokyo subway Sarin gas attack suffer from chronic neurological problems …

Two Sampling Methods Yield Distinct Microbial Signatures In The Nasopharynges Of Asthmatic Children., Marcos Pérez-Losada, Keith A. Crandall, Robert J. Freishtat

Pediatrics Faculty Publications

Background

The nasopharynx is a reservoir for pathogens associated with respiratory illnesses, such as asthma. Next-generation sequencing (NGS) has been used to characterize the nasopharyngeal microbiome during health and disease. Most studies so far have surveyed the nasopharynx as a whole; however, less is known about spatial variation (biogeography) in nasal microenvironments and how sampling techniques may capture that microbial diversity.

Findings

We used targeted 16S rRNA MiSeq sequencing and two different sampling strategies [nasal washes (NW) and nasal brushes (NB)] to characterize the nasopharyngeal microbiota in 30 asthmatic children. Nasal brushing is more abrasive than nasal washing and targeted …

Different Vancomycin Immunoassays Contribute To The Variability In Vancomycin Trough Measurements In Neonates, Janko Samardzic, Anne Smits, Isabel Spriet, Ivan Soldatovic, Andrew Atkinson, Milica Bajcetic, John N. Van Den Anker, Karel Allegaert

Pediatrics Faculty Publications

Substantial interassay variability (up to 20%) has been described for vancomycin immunoassays in adults, but the impact of neonatal matrix is difficult to quantify because of blood volume constraints in neonates. However, we provide circumstantial evidence for a similar extent of variability. Using the same vancomycin dosing regimens and confirming similarity in clinical characteristics, vancomycin trough concentrations measured by PETINIA (2011-2012, n = 400) were 20% lower and the mean difference was 1.93 mg/L compared to COBAS (2012–2014, n =352 ) measurements. The impact of vancomycin immunoassays in neonatal matrix was hereby suggested, supporting a switch to more advanced techniques …

Recent Fast Food Consumption And Bisphenol A And Phthalates Exposures Among The U.S. Population In Nhanes, 2003-2010, Ami R. Zota, Cassandra Phillips, Susanna D. Mitro

Environmental and Occupational Health Faculty Publications

Background: Phthalates and bisphenol A (BPA) are widely used industrial chemicals that may adversely impact human health. Human exposure is ubiquitous and can occur through diet, including consumption of processed or packaged food.

Objective: To examine associations between recent fast food intake and BPA and urinary metabolites of di(2-ethylhexyl) phthalate (ΣDEHPm) and diisononyl phthalate (DiNPm) among the US population.

Methods: We combined data on 8877 participants from the National Health and Nutrition Examination Survey (NHANES 2003-2010). Using 24-hour dietary recall data, we quantified: 1) fast food intake (percent of total energy intake (TEI) from fast food); 2) fast food-derived fat …

Cryptosporidium Priming Is More Effective Than Vaccine For Protection Against Cryptosporidiosis In A Murine Protein Malnutrition Model, Luther A. Bartelt, David T. Bolick, Glynis L. Kolling, James K. Roche, Edna I. Zaenker, Ana M. Lara, Francisco Jose Noronha, Carrie A. Cowardin, John H. Moore, Jerrold R. Turner, Cirle A. Warren, Gregory A. Buck, Richard L. Guerrant

Biochemistry and Molecular Biology Publications

Cryptosporidium is a major cause of severe diarrhea, especially in malnourished children. Using a murine model of C. parvum oocyst challenge that recapitulates clinical features of severe cryptosporidiosis during malnutrition, we interrogated the effect of protein malnutrition (PM) on primary and secondary responses to C. parvum challenge, and tested the differential ability of mucosal priming strategies to overcome the PM-induced susceptibility. We determined that while PM fundamentally alters systemic and mucosal primary immune responses to Cryptosporidium, priming with C. parvum (106 oocysts) provides robust protective immunity against re-challenge despite ongoing PM. C. parvum priming restores mucosal Th1-type effectors (CD3+CD8+CD103+ T-cells) …

Constitutive Association Of Tie1 And Tie2 With Endothelial Integrins Is Functionally Modulated By Angiopoietin-1 And Fibronectin, Annamarie C. Dalton, Tomer Shlamkovitch, Niv Papo, William A. Barton

Biochemistry and Molecular Biology Publications

Functional cross-talk between Tie2 and Integrin signaling pathways is essential to coordinate endothelial cell adhesion and migration in response to the extracellular matrix, yet the mechanisms behind this phenomenon are unclear. Here, we examine the possibility that receptor cross-talk is driven through uncharacterized Tie-integrin interactions on the endothelial surface. Using a live cell FRET-based proximity assay, we monitor Tie-integrin receptor recognition and demonstrate that both Tie1 and Tie2 readily associate with integrins α5ß1 and αVß3 through their respective ectodomains. Although not required, Tie2-integrin association is significantly enhanced in the presence of the extracellular component and integrin ligand fibronectin. In vitro …

Midterm Follow Up For Knee Replacement: How Well Do We Follow Our Patients?, Micah Mabe, William Jiranek Md, Gregory Golladay Md

MD Student Summer Research Fellowship Program Posters

The lost to follow up rate specifically for five year post surgical UKAs is significantly higher for this population subset than the most recent published average as seen in a meta analysis review (Callahan et al. 1995). Follow up visits allow for proper assessment of complications such as wear and osteolysis which need early intervention to improve long-term outcomes and reduce the overall cost of care (Bhandari et al. 2012). Eleven patients, 27.5% of those that were lost to follow up, were without a correct or working phone number, which presents a significant barrier to care. Maintaining updated patient contact …

Impact Of Morbid Obesity On Left Ventricular Assist Device Support And Heart Transplantation, Sophia Cohen, Daniel Tang Md

MD Student Summer Research Fellowship Program Posters

Morbidly obese patients requiring LVAD support encounter higher postoperative complications and wait longer for heart transplantation, however heart transplant and graft survival is comparable. Our study suggests that carefully selected morbidly obese patients should undergo LVAD placement and heart transplantation. However, our study was limited by a very small sample size and by the biases inherent to a retrospective data analysis.

Underuse And Potential Detrimental Effect Of Radiotherapy In The Management Of Ureteral Cancer, Reza Nabavizadeh, Mashya Abbassi, Emma C. Fields Md

MD Student Summer Research Fellowship Program Posters

Ureteral cancer is extremely rare, with only 3530 cases predicted in 2016. Therefore, published studies on ureteral cancers are limited to single-institution retrospective studies, which have not elucidated a clear recommendation on the best treatment modality. Large cancer databases such as the Surveillance, Epidemiology, and End Results program (SEER) are ideal for providing data for these rare cancers. Epidemiological studies using the SEER database with large sample sizes (13,800) found rising incidence of ureteral cancer over the past 30 years with worsened outcomes in older patients, males, and patients with regional/distant spread. However, to date, these studies have not used …

Can Plan Recommendations Improve The Coverage Decisions Of Vulnerable Populations In Health Insurance Marketplaces?, Andrew J. Barnes, Yaniv Hanoch, Thomas Rice

Health Administration Publications

Objective

The Affordable Care Act’s marketplaces present an important opportunity for expanding coverage but consumers face enormous challenges in navigating through enrollment and re-enrollment. We tested the effectiveness of a behaviorally informed policy tool—plan recommendations—in improving marketplace decisions.

Study Setting

Data were gathered from a community sample of 656 lower-income, minority, rural residents of Virginia.

Study Design

We conducted an incentive-compatible, computer-based experiment using a hypothetical marketplace like the one consumers face in the federally-facilitated marketplaces, and examined their decision quality. Participants were randomly assigned to a control condition or three types of plan recommendations: social normative, physician, and government. …
