Eichhornia crassipes (water hyacinth) is an invasive weed that causes serious issues for rivers, lakes, and other reservoirs around the world, although it can be an excellent source for bioactive compounds such as phytosterols and some steroids found in many plants. In this study, water hyacinth samples from both Durango and Distrito Federal in Mexico were collected. Ascendant extracts (cyclohexane, hexane, acetone, and methanol) from their leaves, stems, and roots were analyzed. Using boron trifluoride (similar to 10% [similar to 1.3 M] in 1-butanol), all extracts were derivatized. Twenty-four derivatized samples were analyzed using a gas chromatography-mass spectrometry (GC/MS) method. …

Brown, Khalil Harbi, Leah R. Alexander, Ann L. Coker, Maria E. Fernandez, Heather M. Brandt, Mary K. Fadden, Pamela C. Hull

Obstetrics and Gynecology Faculty Publications

A clinic-based intervention study was conducted among high-risk human papillomavirus (HPV)-infected Latinas aged 18-64 years between April 2006 and May 2008 on the Texas-Mexico border. Women were randomly assigned to receive a printed material intervention (n=186) or usual care (n=187) and were followed at three months, six months, and 12 months through telephone surveys and review of medical records. The HPV knowledge of nearly all women had increased greatly, but only two-thirds of women reported they had received follow-up care within one year of diagnosis regardless of additional health education messaging. Our findings suggest that, regardless of type of health …

Serum Proteins Enhance Dispersion Stability And Influence The Cytotoxicity And Dosimetry Of Zno Nanoparticles In Suspension And Adherent Cancer Cell Models, Catherine B. Anders, Jordan J. Chess, Denise G. Wingett, Alex Punnoose

Biomedical Research Institute Publications and Presentations

Agglomeration and sedimentation of nanoparticles (NPs) within biological solutions is a major limitation in their use in many downstream applications. It has been proposed that serum proteins associate with the NP surface to form a protein corona that limits agglomeration and sedimentation. Here, we investigate the effect of fetal bovine serum (FBS) proteins on the dispersion stability, dosimetry, and NP-induced cytotoxicity of cationic zinc oxide nanoparticles (nZnO) synthesized via forced hydrolysis with a core size of 10 nm. Two different in vitro cell culture models, suspension and adherent, were evaluated by comparing a phosphate buffered saline (PBS) nZnO dispersion (nZnO/PBS) …

Promoting Public Health In The Context Of The “Obesity Epidemic”: False Starts And Promising New Directions, T. Mann, A. J. Tomiyama, Andrew Ward

Psychology Faculty Works

In the battle to combat obesity rates in the United States, several misconceptions have dominated policy initiatives. We address those misconceptions, including the notion that restrictive diets lead to long-term weight loss, that stigmatizing obesity is an effective strategy for promoting weight reduction, and that weight and physical health should be considered synonymous with one another. In offering correctives to each of these points, we draw on psychological science to suggest new policies that could be enacted at both the local and national levels. Instead of policies that rely solely on individual willpower, which is susceptible to failure, we recommend …

Vegetable Production Guide For Commercial Growers, 2016-17, Shubin Saha, Emily Pfeufer, Ricardo Bessin, Shawn Wright, John Strang

Agriculture and Natural Resources Publications

Successful vegetable production generally requires the grower to make daily decisions regarding pest management, irrigation, and cultural practices. Would-be growers unwilling to make serious investments of time (and money) should not attempt to expand beyond a space at the farmers’ market. It is important for vegetable growers to have a market outlet for their product before they choose to start production. Good marketing plans start with the customer and work backward to production. Potential growers should first determine exactly what buyers want, how they want it, and when they want it. They then must determine how these crops should be …

Use Of Modeling And Simulation In The Design And Conduct Of Pediatric Clinical Trials And The Optimization Of Individualized Dosing Regimens, Chris Stockmann, J. S. Barrett, Jessica K. Roberts, Catherine M.T. Sherwin

Pediatrics Faculty Publications

Mathematical models of drug action and disease progression can inform pediatric pharmacotherapy. In this tutorial, we explore the key issues that differentiate pediatric from adult pharmacokinetic (PK) / pharmacodynamic (PD) studies, describe methods to calculate the number of participants to be enrolled and the optimal times at which blood samples should be collected, and therapeutic drug monitoring methods for individualizing pharmacotherapy. The development of pediatric‐specific drug dosing dashboards is also highlighted, with an emphasis on clinical‐relevance and ease of use.

Intake as a fraction of thermoneutral intake (FFI) was the primary response variable, where a value of 1 represented no change from thermoneutral …

Exploring An Accelerated College Program For Adult Learners: A Program Evaluation, Charlene Engleking

Dissertations

Many colleges and universities have expanded their mission to include adult learners. Programs range from scheduling traditional courses in the evening to designing new programs tailored to meet the needs of working adults. Program designers have relied on theorists such, as Mezirow (1991), Houle (1996), and Knowles, Holton, and Swanson (1998), to develop programs that apply adult learning theory. Lindenwood College, now Lindenwood University, established The Lindenwood College for Individualized Education (LCIE) in 1975 to serve adult students in the St. Louis metropolitan area. The program has evolved over the course of 40 years, and this program evaluation evaluated the …

Using Geometry To Manipulate Long-Range Correlation Of Light Inside Disordered Media, Raktim Sarma, Alexey Yamilov, Pauf Neupane, Hui Cao

Physics Faculty Research & Creative Works

We demonstrate an effective approach of modifying the long-range spatial correlation for light propagating inside random photonic waveguides by varying the shape of the waveguide. The functional form of spatial correlation is no longer universal in the regime of diffusive transport and becomes shape dependent due to the nonlocal nature of wave propagation. The spatial dependence of the correlation may become asymmetric for light incident from opposite ends of the waveguide. This work opens the door to control nonlocal effects in mesoscopic transport of waves by tailoring the geometry of random systems. .

Infinite-Noise Criticality: Nonequilibrium Phase Transitions In Fluctuating Environments, Thomas Vojta, José A. Hoyos

Physics Faculty Research & Creative Works

We study the effects of time-varying environmental noise on nonequilibrium phase transitions in spreading and growth processes. Using the examples of the logistic evolution equation as well as the contact process, we show that such temporal disorder gives rise to a distinct type of critical points at which the effective noise amplitude diverges on long time scales. This leads to enormous density fluctuations characterized by an infinitely broad probability distribution at criticality. We develop a real-time renormalization-group theory that provides a general framework for the effects of temporal disorder on nonequilibrium processes. We also discuss how general this exotic critical …

Faculty Publications

© 2015 Society for Ecological Restoration. Shrub encroachment occurring worldwide in savannas and grasslands has commonly been hypothesized to result from anthropogenically altered environments. Two disturbance-based approaches to restoration have involved: (1) application of selective herbicides to reduce density/cover of shrubs; (2) reinstatement of natural fire regimes to generate environmental conditions favoring herbaceous species. We studied short-term responses of native shrubs, vines, and grasses in a Louisiana pine savanna to herbicides followed by a prescribed fire and fire alone. Plots established in the summer, 2013, were hand-sprayed in the fall with Imazapyr and Triclopyr, Triclopyr alone, or no herbicide, then …

Fetal Programming In Meat Production, Min Du, Bo Wang, Xing Fu, Qiyuan Yang, Mei Jun Zhu

Faculty Publications

© 2015 Elsevier Ltd. Nutrient fluctuations during the fetal stage affects fetal development, which has long-term impacts on the production efficiency and quality of meat. During the early development, a pool of mesenchymal progenitor cells proliferate and then diverge into either myogenic or adipogenic/fibrogenic lineages. Myogenic progenitor cells further develop into muscle fibers and satellite cells, while adipogenic/fibrogenic lineage cells develop into adipocytes, fibroblasts and resident fibro-adipogenic progenitor cells. Enhancing the proliferation and myogenic commitment of progenitor cells during fetal development enhances muscle growth and lean production in offspring. On the other hand, promoting the adipogenic differentiation of adipogenic/fibrogenic progenitor …

Boundary Between Human And Machine, Seulgi Cho

Theses

John McCathy and Peter Wright, who are technology philosophers while also being engineers, analyzed the technology of today and found that it transcends the mere role of being everyday tools, and claim that technology has such a significant existence that it can influence the emotions of humans. The products of technology such as machines that have become everyday parts of our lives are no longer simple tools, but their meanings in our lives have expanded into something more complex. The products of technology, they point out, influence and change the sense of perception and emotional state of people. But, to …

Communicating Through Distraction: A Study Of Deaf Drivers And Their Communication Style In A Driving Environment, Pierce T. Hamilton

Theses

This study will investigate the driving habits of deaf drivers and the manners in which they adapt to their driving experience. The lack of an auditory sense presents some unique challenges. While it is clear that driving is a predominantly visual task, auditory stimulation is still a part of the driving experience. This study seeks to determine how deaf drivers cope in a driving environment despite hearing loss. The results of the study will help to inform policy that can make the driving experience safer.
