Fabrication Of Miniature Drug Screening Platform Using Low Cost Bioprinting Technology, Jorge Ivan Rodriguez

Open Access Theses & Dissertations

In the pharmaceutical industry, new chemicals and substances are being tested to find appropriate compounds or mix for treating a specific disease. The demand for screening large compound collections against and increasing number of therapeutic targets has stimulated technology development in the areas of assay automation and miniaturization. Current methods for evaluating the reactions of cells use a volume in the range of microliters. We have developed a new and low-cost deposition method to fabricate miniature drug screening platform that can realistically and inexpensively evaluate biochemical reactions up to 4 substances per trial in a picoliter-scale volume. This paper describes …

Effects Of The Loss Of Multidrug Resistance Associated Protein 1 On Steroid Homeostasis, Dendritic Cell Function And Compensatory Mechanisms, Jeffrey Charles Sivils

Open Access Theses & Dissertations

The ATP-binding cassette (ABC) superfamily of membrane transporters use energy derived from ATP to eliminate a variety of exogenous and endogenous compounds from cells including anti cancer and anti viral drugs, metals steroids, bilirubin, cAMP, cGMP, leukotrienes , prostaglandins. The multi drug resistance associated protein family (MRP/ABBC) has been acknowledged as a major player involved in multi drug resistance (MDR), in which cancers stop responding a wide array of structurally and functionally unrelated chemotherapy drugs. Cancer is the second leading cause of death in adults in the United States. Although there have been great strides made the treatment of cancers …

The Role Of Generation And Monitoring Processes In Governing The Paradoxical Effects Of Retrieval On Memory For Faces, Kyle Joseph Susa

Open Access Theses & Dissertations

Verbal descriptions of faces can at times impair and at other times facilitate subsequent face identification accuracy. Three experiments were conducted from a retrieval-based theoretical perspective to determine the underlying cognitive processes that can account for these paradoxical findings. Results demonstrated that the verbal description-identification relationship is analogous to other domains of memory where an initial retrieval of memory can have both positive and negative effects on subsequent retrieval attempts. Results of Experiment 1 showed that verbal facilitation is a product of self-generated descriptions that enrich the semantic encoding of the original memory trace. Experiments 2 and 3 demonstrated that …

Acoustic Reflectometry Using Gaussian-Modulated Sinusoidal Waves And The Ware-Aki Algorithm, Ernesto Rodrigo Vazquez Ceron

Open Access Theses & Dissertations

Acoustic reflectometry, a non invasive technique, consists of solving, the inverse problem of estimating the cross sectional area as function of the distance of a cylindrical cavity by impacting an audible acoustic pulse of high amplitude and short duration, and analyzing the reflected wave. The technique has been applied in Biomedical Engineering to estimate both the area of a human upper airway and the patency of endotracheal tubes as a function of distance. Several ways have been tested to improve the quality of an acoustic pulse and different algorithms have been tested to reduce the losses. However, an acoustic pulse …

Dominant Discourses Embedded In Popular Culture: An Analysis Of Brazilian Teachers` Consciousness, Luciene Soares Wandermurem

Open Access Theses & Dissertations

Many scholars believe that popular culture is part of students` identity and a symbol of subordinated groups` resistance to cultural domination, therefore they support the use of popular culture in the classroom as a way to value students` identity. However, scholars also recognize that often times popular culture is manipulated by elites so as to convey discourses that oppress people of color as an strategy to maintain the status quo. In Brazil, country where this research was conducted, white male individuals are the ones who have historically held power and money, utilizing the media as an instrument of social control. …

Physical And Biochemical Assessment Of Mexican Palo Verde Response To Chromium Toxicity, Yong Zhao

Open Access Theses & Dissertations

In the United States, about 1/3 of the 1400 superfund sites have been reported to be chromium contaminated, making chromium the second most common metal found in superfund chemical contamination sites. Chromium removal from soil has commonly been carried out via chemical, physical, and thermal processes. However, these methods are expensive and/or invasive to local ecosystems. In contrast to these techniques, phytoremediation (the use of plants to remove toxic substances from areas containing contamination at low or medium levels) appears to be a cost-effective and environmentally friendly process for chromium removal. However, most reports on chromium phytoremediation suggest that this …

Assessment Of Total Organic Carbon Concentrations In Two Streams Of Northwest Arkansas: Town Branch And Brush Creek, Abigail N. Washispack, Jason A. Mcginnis, Brian E. Haggard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Within a stream, changes in flow rate and local environment can affect the total organic content (TOC) concentrations in the stream water and TOC delivery downstream to water supply reservoirs. Disinfection by-products (DBPs) result from various chemical reactions between chlorine, bromine, and organic carbon in raw water during the drinking water treatment process; DBPs are potential carcinogens and are regulated by the U.S. Environmental Protection Agency. In this project, we measured the TOC concentrations in two streams in the Beaver Lake Watershed: Town Branch and Brush Creek. We then compared TOC concentrations between the two streams and to that observed …

Reach Your Campus, Reach The World: Prioritizing Our Mission To And Through Those In Schools, Steve Case

All Books

DESCRIPTION

An estimated 70% of Seventh-day Adventist college and university students attend non-church sponsored schools. Many of these students are not finding a spiritual community they can connect with, creating a tremendous need for public campus ministry.

How can the Seventh-day Adventist Church intentionally foster biblical community on public college and university campuses? How can we reach both Adventist and non-Adventist students? How should we conduct evangelism to fit a changing world? These and many other questions were addressed at the 2009 180º Symposium held on the campus of Andrews University.

Papers presented at the 180º Symposium covered three major …
