Penicillin Allergy Assessment And Skin Testing In The Outpatient Setting, Wesley D. Kufel, Julie Ann Justo, P. Brandon Bookstaver, Lisa M. Avery

Faculty Publications

Penicillin allergies are among of the most commonly reported allergies, yet only 10% of these patients are truly allergic. This leads to potential inadvertent negative consequences for patients and makes treatment decisions challenging for clinicians. Thus, allergy assessment and penicillin skin testing (PST) are important management strategies to reconcile and clarify labeled penicillin allergies. While PST is more common in the inpatient setting where the results will immediately impact antibiotic management, this process is becoming of increasing importance in the outpatient setting. PST in the outpatient setting allows clinicians to proactively de-label and educate patients accordingly so beta-lactam antibiotics may …

Adhami, Andrea L. Noll, Sergette Banang-Mbeumi, Tithi Roy, Sitanshu S. Singh, Shile Huang, Konstantin G. Kousoulas, Hasan Mukhtar

Faculty Publications

Psoriasis is a chronic immune-mediated skin disease that involves the interaction of immune and skin cells, and is characterized by cytokine-driven epidermal hyperplasia, deviant differentiation, inflammation, and angiogenesis. Because the available treatments for psoriasis have significant limitations, dietary products are potential natural sources of therapeutic molecules, which can repair the molecular defects associated with psoriasis and could possibly be developed for its management. Fisetin (3,7,3',4'-tetrahydroxyflavone), a phytochemical naturally found in pigmented fruits and vegetables, has demonstrated proapoptotic and antioxidant effects in several malignancies. This study utilized biochemical, cellular, pharmacological, and tissue engineering tools to characterize the effects of fisetin on …

Methods The present prospective longitudinal study examined the trajectory of negative affect from infancy through preschool in males and females with FXS and typical development and its relation to anxiety and ASD.

Results Results indicate a complex association reflecting group, developmental, and sex effects. Specifically, the group with FXS displayed a trajectory of increasing negative …

Perceived Parental Psychological Control Predicts Intraindividual Decrements In Self-Regulation Throughout Adolescence, Laura M. Padilla-Walker, Adam A. Rogers, Madison K. Memmott-Elison

Faculty Publications

The present study examined the intraindividual, longitudinal, cross-lagged associations between adolescents’ perceptions of mothers’ and fathers’ psychologically controlling parenting and their self-regulation from ages 11–17. Using 7 waves of data involving 500 families and their adolescents (Mage 11.29; SD 1.01 at Wave 1), results indicated that adolescent-reported increases in mothers’ and fathers’ psychological control prospectively and uniquely predicted intraindividual decrements in their self- regulation, controlling for prior levels of self-regulation. Sex differences were largely absent except for one, where fathers’ psychological control predicted adolescent females’, but not males’, declines in self-regulation, and where reverse associations manifested. Implications for intervention efforts …

Faculty Publications

For this study, we applied activated biochar (AB) and its composition with magnetite (AB-Fe₃O₄) as adsorbents for the removal of polychlorophenols in model wastewater. We comprehensively characterized these adsorbents and performed adsorption tests under several experimental parameters. Using FTIR, we confirmed successful synthesis of AB-Fe₃O₄ composite through cetrimonium bromide surfactant. We conducted adsorption tests using AB and AB-Fe₃O₄ to treat model wastewater containing polychlorophenols, such as 2,3,4,6-Tetrachlorophenol (TeCP), 2,4,6-Trichlorophenol (TCP), and 2,4-Dichlorophenol (DCP). Results of the isotherm and the kinetic experiments were well adapted to Freundlich’s isotherm model and the …

Exploration Of Factors Associated With Perceived Barriers To Cervical Cancer Screening Among Chinese American Women, Wei-Chen Tung, Minggen Lu, Michelle Granner, Jiani Mcdonough, Susan Ervin

Faculty Publications

This study explored factors associated with perceived barriers to Pap smear testing among Chinese American women (CAW). A total of 121 CAW, ages 21–65, living in California and Nevada completed a self-report questionnaire. Data included demographics, prior screening behavior, risk factors, and perceived barriers to screening. Logistic regression models revealed that participants with less education, and who have never been screened were more likely to report (I) worry about getting a Pap smear, (II) expense of a Pap smear, and (III) not knowing where to get a Pap smear. Partner’s resistance to the women’s participation in screening was another barrier …

Multilevel Analysis In Rural Cancer Control: A Conceptual Framework And Methodological Implications, Tine Verreet, Cory J. Weaver, Hiromu Hino, Masahiko Hibi, Fabienne E. Poulain

Faculty Publications

Mitochondria are abundantly detected at the growth cone, the dynamic distal tip of developing axons that directs growth and guidance. It is, however, poorly understood how mitochondrial dynamics relate to growth cone behavior in vivo, and which mechanisms are responsible for anchoring mitochondria at the growth cone during axon pathfinding. Here, we show that in retinal axons elongating along the optic tract in zebrafish, mitochondria accumulate in the central area of the growth cone and are occasionally observed in filopodia extending from the growth cone periphery. Mitochondrial behavior at the growth cone in vivo is dynamic, with mitochondrial positioning …

Faculty Publications

(1) Background: Smoking restrictions have been shown to be associated with reduced smoking, but there are a number of gaps in the literature surrounding the relationship between smoke-free policies and cessation, including the extent to which this association may be modified by sociodemographic characteristics. (2) Methods: We analyzed data from the Tobacco Use Supplement to the Current Population Survey, 2003–2015, to explore whether multiple measures of smoking restrictions were associated with cessation across population subgroups. We examined area-based measures of exposure to smoke-free laws, as well as self-reported exposure to workplace smoke-free policies. We used age-stratified, fixed effects logistic regression …

The Tensile Root Strength Of Spartina Patens Varies With Soil Texture And Atrazine Concentration, Lauris O. Hollis, R. Eugene Turner

Faculty Publications

The widely used agricultural herbicide atrazine enters wetlands and may potentially affect wetland plants that provide critical reinforcement of soil strength and contribute to ecosystem stability in ways that may vary among soil types. We conducted greenhouse experiments using four levels of atrazine doses and three different soil textures to test for differences between control and experimental treatments and interactive effects of soil texture and atrazine exposure by using the tensile root strength of the coastal wetland emergent macrophyte Spartina patens as the response variable. The tensile root strength of S. patens was not affected after 50days of atrazine exposure …

Faculty Publications

© 2019 American Society for Microbiology. All Rights Reserved. Hypoxia and hypoxia inducible factors (HIFs) play important roles in the Kaposi’s sarcoma-associated herpesvirus (KSHV) life cycle. KSHV is the causative agent of Kaposi’s sarcoma (KS) and other AIDS-related malignancies. Kaposi’s sarcoma is a highly vascular tumor, which preferentially develops in the lower extremities of the body where blood vessels are often poorly oxygenated. The main cellular responses to hypoxia are mediated mainly by two isoforms of HIF, HIF-1 and HIF-2. HIF-1 and HIF-2 have common as well as distinct functions, although they are similar in structure and function. Previously, we …

Thermal And Physico-Mechanical Characterizations Of Thromboresistant Polyurethane Films, Aaron C. Wilson, Shih Feng Chou, Roberto Lozano, Jonathan Y. Chen, Pierre F. Neuenschwander

Faculty Publications

Hemocompatibility remains a challenge for injectable and/or implantable medical devices, and thromboresistant coatings appear to be one of the most attractive methods to down-regulate the unwanted enzymatic reactions that promote the formation of blood clots. Among all polymeric materials, polyurethanes (PUs) are a class of biomaterials with excellent biocompatibility and bioinertness that are suitable for the use of thromboresistant coatings. In this work, we investigated the thermal and physico-mechanical behaviors of ester-based and ether-based PU films for potential uses in thromboresistant coatings. Our results show that poly(ester urethane) and poly(ether urethane) films exhibited characteristic peaks corresponding to their molecular configurations. …

Collision With Collusion: Partisan Reaction To The Trump-Russia Scandal, Joshua P. Darr, Nathan P. Kalmoe, Kathleen Searles, Mingxiao Sui, Raymond J. Pingree, Brian K. Watson, Kirill Bryanov, Martina Santia

Faculty Publications

President Donald Trump faced substantial scandal coverage early in his presidency. Can these stories about presidential controversies change the opinions of Trump's fellow Republicans, or are the efforts of the news media to inform partisans about prominent issues futile? Past research on partisan reactions to major political scandals were confounded by problems with self-reported media use and single-shot experimental treatments. We address these concerns using a unique, repeated-exposure experimental design that either randomly supplied participants with news about the Trump-Russia scandal, or removed most of those stories from view, over the course of one week in June 2017. This design …

Residence Time Effects On Molybdenum Adsorption On Soils: Elucidation By Multi-Reaction Modeling And Xanes Analysis, Wenguang Sun, Amitava Roy, H. Magdi Selim

Faculty Publications

To investigate the influence of residence time on molybdenum [Mo(VI)] adsorption behavior in soil environments, kinetic batch experiments coupled with X-ray near-edge structure (XANES) spectroscopy were performed for a neutral-pH soil (Webster loam) and two acidic soils (Mahan sand and Windsor sand) at different time scales (1 day–1 year). Batch-type experiments indicated that retention of Mo(VI) was rate limited and typical biphasic for soils. Initial rapid retention was followed by a continued slow retention with increasing aging time for Mahan and Windsor soils. In contrast, the reaction for Webster soil was nearly complete after 8 h, reflecting difference in soil …

Situational Factors Influencing Receptivity To Bullshit, Mitch Brown, Lucas A. Keefer, Shelby J. Mcgrew

Faculty Publications

Individuals are motivated to maintain a sense of meaning, and enact cognitive processes to do so (e.g., perceiving structure in the environment). This motivation to find meaning may ultimately impact humans’ interpretation of "bullshit", statements intended to convey profundity without any meaning. Conversely, subtle cues threatening the meaningfulness of bullshit may elicit greater skepticism. Three studies tested situational factors predicted to heighten or diminish susceptibility to bullshit by changing motivations to seek meaning. We employed diverse methods including symbolic meaning threat (Study 1), social exclusion (Cyberball; Study 2), and manipulating cognitive fluency (Study 3). Taken together, the results indicate basic …
