About six in ten Kenyans are unable to afford healthcare, clothing, or food; therefore, oral healthcare has …

Alterations In Default Network Connectivity In Posttraumatic Stress Disorder Related To Early Life Trauma, Robyn L. Bluhm, Peter C. Williamson, Elizabeth A. Osuch, Paul A. Frewen, Todd K. Stevens, Kristine Boksman, Richard W.J. Neufeld, Jean Théberge, Ruth A. Lanius

Philosophy Faculty Publications

Background: The "default network" consists of a number of brain regions that exhibit correlated low-frequency activity at rest and that have been suggested to be involved in the processing of self-relevant stimuli. Activity in many of these areas has also been shown to be altered in individuals with posttraumatic stress disorder (PTSD). We hypothesized that the posterior cingulate cortex (PCC)/precuneus, part of the default network, would exhibit altered connectivity at rest with other areas of the default network and regions associated with PTSD.

Methods: Seventeen medicated and unmedicated female patients with chronic posttraumatic stress disorder (PTSD) related to early-life trauma …

The Cultural Production Of Health Inequalities: A Cross-Sectional, Multilevel Examination Of 52 Countries, Carol L. Mansyur, Benjamin C. Amick Iii, Ronald B. Harrist, Luisa Franzini, Robert E. Roberts

Community & Environmental Health Faculty Publications

In a 2001 report, the U.S. National Institutes of Health called for more integration of the social sciences into health-related research, including research guided by theories and methods that take social and cultural systems into consideration. Based on a theoretical framework that integrates Hofstede's cultural dimensions with sociological theory, the authors used multilevel modeling to explore the association of culture with structural inequality and health disparities. Their results support the idea that cultural dimensions and social structure, along with economic development, may account for much of the cross-national variation in the distribution of health inequalities. Sensitivity tests also suggest that …

Baldwin, Saleh Sheikh, Jennifer L. Pomicter, Wei Ren, Chris Osgood, R. James Swanson, Juergen F. Kolb, Stephen J. Beebe, Karl H. Schoenbach

Bioelectrics Publications

We have discovered a new, ultrafast therapy for treating skin cancer that is extremely effective with a total electric field exposure time of only 180 mu sec. The application of 300 high-voltage (40 kV/cm), ultrashort (300 nsec) electrical pulses to murine melanomas in vivo triggers both necrosis and apoptosis, resulting in complete tumor remission within an average of 47 days in the 17 animals treated. None of these melanomas recurred during a 4-month period after the initial melanoma had disappeared. These pulses generate small, long-lasting, rectifying nanopores in the plasma membrane of exposed cells, resulting in increased membrane permeability to …

Culture And The Social Context Of Health Inequalities, Carol Leler Mansyur, Benjamin C. Amick Iii, Luisa Franzini, Robert E. Roberts

Community & Environmental Health Faculty Publications

There is a great deal of recent interest and debate concerning the linkages between inequality and health cross-nationally. The U.S. National Institutes of Health recommended in 2001 that any new research on health disparities should include social and cultural systems as units of analysis. Nevertheless, many public health interventions and policies continue to decontextualize risk factors from the social environment. Exposures to social and health inequalities probably vary as a consequence of different cultural contexts. To identify the processes that cause social and health inequalities, it is important to understand culture's influence. Navarro's research on political institutions and inequality illustrates …

Probing The Urea Dependence Of Residual Structure In Denatured Human Α-Lactalbumin, Victoria A. Higman, Heike I. Rösner, Raffaella Ugolini, Lesley H. Greene, Christina Redfield, Lorna J. Smith

Chemistry & Biochemistry Faculty Publications

Backbone ¹⁵N relaxation parameters and ¹⁵N–¹H^N residual dipolar couplings (RDCs) have been measured for a variant of human α-lactalbumin (α-LA) in 4, 6, 8 and 10 M urea. In the α-LA variant, the eight cysteine residues in the protein have been replaced by alanines (all-Ala α-LA). This protein is a partially folded molten globule at pH 2 and has been shown previously to unfold in a stepwise non-cooperative manner on the addition of urea. ¹⁵N R₂ values in some regions of all-Ala α-LA show significant exchange broadening which is reduced as the urea …

Optimizing Computer-Aided Colonic Polyp Detection For Ct Colonography By Evolving The Pareto Front, Jiang Li, Adam Huang, Jack Tao, Jiamin Liu, Robert L. Van Uitert, Nicholas Petrick, Ronald Summers

Electrical & Computer Engineering Faculty Publications

A multiobjective genetic algorithm is designed to optimize a computer-aided detection (CAD) system for identifying colonic polyps. Colonic polyps appear as elliptical protrusions on the inner surface of the colon. Curvature-based features for colonic polyp detection have proved to be successful in several CT colonography (CTC) CAD systems. Our CTC CAD program uses a sequential classifier to form initial polyp detections on the colon surface. The classifier utilizes a set of thresholds on curvature-based features to cluster suspicious colon surface regions into polyp candidates. The thresholds were previously chosen experimentally by using feature histograms. The chosen thresholds were effective for …

Physics Faculty Publications

The effectiveness and mechanism of a low temperature air plasma torch in clotting blood are explored. Both blood droplets and smeared blood samples were used in the tests. The treated droplet samples reveal how blood clotting depends on the distance at which the torch operated, and for how long the droplets have been exposed to the torch. Microscopy and cell count of smeared blood samples shed light on dependencies of erythrocyte and platelet counts on torch distance and exposure time. With an increase of torch distance, the platelet count of treated blood samples increases but is less than that of …

Traumatic Stress As A Predictor Of Suicidality, Sherry Malana Todd

Counseling & Human Services Theses & Dissertations

Suicide is a deliberate act of annihilation against one's self due to a crisis of problem solving. Far too many youth are dying by their own hands resulting in suicide being the third leading cause of death for 10-19 year olds (CDC, 2005). Suicide is particularly problematic for adolescents due to the impulsivity inherent in adolescent development. Since 1980, the national suicide rate of African American youth has increased by 114 percent (CDC). Suicidality has been positively correlated with depression and posttraumatic stress disorder (PTSD; Kessler et al., 1999). Suicidality is more prevalent when a person experiences a tragic or …
