Aligned peptide-functionalize nanofiber microsheets were generated with calcium phosphate (CaP) content similar to that of the natural cortical bone. Next, the CaP-rich fibrous microsheets were wrapped around a microneedle to form a laminated microtube mimicking the structure of an osteon. Then, a set of the osteon-mimetic microtubes were assembled around a solid rod and the assembly was annealed to fuse the microtubes and form a shell. Next, an array of circular microholes were drilled on the outer …

Establishment Of Listeria Monocytogenes In The Gastrointestinal Tract, Morgan L. Davis, Steven C. Ricke, Janet R. Donaldson

Faculty Publications

Listeria monocytogenes is a Gram positive foodborne pathogen that can colonize the gastrointestinal tract of a number of hosts, including humans. These environments contain numerous stressors such as bile, low oxygen and acidic pH, which may impact the level of colonization and persistence of this organism within the GI tract. The ability of L. monocytogenes to establish infections and colonize the gastrointestinal tract is directly related to its ability to overcome these stressors, which is mediated by the efficient expression of several stress response mechanisms during its passage. This review will focus upon how and when this occurs and how …

Coupling Computational Fluid Dynamics Simulations And Statistical Moments For Designing Healthy Indoor Spaces, Shamia Hoque, Firoza B. Omar

Faculty Publications

Cross-contamination between occupants in an indoor space may occur due to transfer of infectious aerosols. Computational fluid dynamics (CFD) provides detailed insight into particle transport in indoor spaces. However, such simulations are site-specific. This study couples CFD with statistical moments and establishes a framework that transitions site-specific results to generating guidelines for designing “healthy” indoor spaces. Eighteen cases were simulated, and three parameters were assessed: inlet/outlet location, air changes per hour, and the presence/absence of desks. Aerosol release due to a simulated “sneeze” in a two-dimensional ventilated space was applied as a test case. Mean, standard deviation, and skewness of …

Faculty Publications

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. This study investigates owner and tenant characteristics and differences between these two groups in their participation in federal conservation initiatives. Bivariate probit model analysis, based on a 2016–2017 Louisiana row-crop producer’s survey show that owners, relative to tenant farmers, are more likely to adopt conservation in early years of ownership. The results emphasize the need for mechanisms for tenants in short-term contracts to invest in long-term conservation. Moreover, conservation initiatives should be tailored, as tenant farmers are increasingly farming more land and policies should carefully account for this growing group of …

A Funny Thing Happened On The Way To The Forum: Prospects For An Ethical Theory Of Accountability, Melvin Dubnick

Faculty Publications

This paper is intended to restate the case for the development of an "ethical theory of accountability" as an alternative to current theoretical frames being applied by students of accountable governance. I would emphasize the word "alternative" at this juncture, noting that an ethical theory should not be regarded as replacement for current models; rather it is offered as a reframing of accountability that can provide a significantly different perspective -- one rooted in (and built upon) ontologically distinct presuppositions about the nature of account-giving/receiving.

Central to the effort is establishing accountability as the capacity to engage in account-giving/receiving behavior …

Faculty Publications

© 2019 the American Physiological Society. previously showed that mice deficient in apo-ptosis signal-regulating kinase-1 (ASK1) were partially protected against ventilator-induced lung injury. Because ASK1 can promote both cell death and inflammation, we hypothesized that ASK1 activation regulates inflammasome-mediated inflammation. Mice deficient in ASK1 expression (ASK1 +/+ ) exhibited significantly less inflammation and lung injury (as measured by neutrophil infiltration, IL-6, and IL-1β) in response to treatment with inhaled lipopolysaccharide (LPS) compared with wild-type (WT) mice. To determine whether this proinflammatory response was mediated by ASK1, we investigated inflammasome-mediated responses to LPS in primary macrophages and bone marrow-derived macrophages (BMDMs) …

The Spatial Distribution Of Poverty And The Long Reach Of The Industrial Makeup Of Places: New Evidence On Spatial And Temporal Regimes, Katherine J. Curtis, Junho Lee, Heather A. O'Connell, Jun Zhu

Faculty Publications

A wealth of research identifies industrial structure as a central correlate of place-level poverty and suggests that changes in and the clustering of industry contribute to the spatial clustering of poverty over time. However, few studies have investigated the spatial and temporal dimensions simultaneously, and none have effectively examined spatiotemporal interactions. Consequently, a core tenet of theory on poverty in place has not been adequately examined. To address this limitation, we explicitly test hypotheses about systematic variation in the poverty-industry relationship over time and across space using a new method to quantify dynamic associations by simultaneously accounting for spatial and …
