Handling History: An Exploration in the Use and Significance of 3D Printing in Museum Exhibits
Museums have long been regarded as sacred spaces, housing a plethora of objects intended to be admires and contemplated upon, but too often they remain physically unreachable. This thesis project seeks to use the process of additive manufacturing, commonly known as 3D printing, to allow visitors to establish a more personal connection with museum items. The exhibit facilitated interaction between the Technology Sandbox and library visitors. This process included selecting items from the collection of the Art Museum of the University of Memphis, digitizing and printing items using the technology available in the Ned R. McWherter Library Technology Sandbox, creating and installing the exhibit using the genuine and replicated items in the rotunda of the library. Additionally, the paper portion of this thesis project documents the project methodology and details the importance of 3D printing in museum settings

Validation of lethality processes for products with slow come up time: Bacon and bone-in ham
Pork bellies and boneless hams were smoked or cooked using unusually long processes to determine the impact of extended come-up times on the populations of Clostridium perfringens, Salmonella enterica, Staphylococcus aureus and Listeria monocytogenes. The products were formulated using brine formulations representative of what might be used in commercial production, and the thermal processes were more than doubled in length. Pork bellies and boneless hams were inoculated on the surface as well as 1 cm below the surface, and samples were collected every 3 h. The populations of C. perfringens (spores and vegetative cells) at internal locations of pork bellies increased by less than 1 log10 and declined significantly (approximately 3 log10/cm2) on the surface of the bellies during an extended bacon process. The populations of S. enterica, L. monocytogenes and S. aureusdid not increase during the extended bacon process. The populations of C. perfringens (spores and vegetative cells), S. aureus, S. enterica and L. monocytogenesdeclined significantly over an extended ham process. There were significant population reductions (\u3e2 log10/cm2) at 7 h (surface) and 12 h (\u3e5 log10/g; internal) for the hams. Populations of both surface and internal locations of the hams declined to a point approaching the limit of detection of the assays within 17 h
Understanding Barriers for Adherence to Follow-Up Care for Abnormal Pap Tests
Objective: Approximately 4000 women annually will die from preventable and treatable cervical cancer. Failure to adhere to follow-up recommendations after an abnormal Pap test can lead to development of cervical cancer. This paper summarizes the body of literature on adherence to follow-up after an abnormal Pap test in order to facilitate development of interventions
to decrease morbidity and mortality due to cervical cancer.
Methods: We conducted a comprehensive search of published literature addressing risk factors for adherence or interventions to improve adherence following an abnormal Pap test as the outcome. We included peer-reviewed original research conducted in the United States from 1990 to 2005.
Results: Fourteen analytical and twelve experimental studies that met our criteria were reviewed. Lesion severity and health beliefs were consistently associated with adherence rates. Communication interventions, including telephone reminders, counseling, and educational sessions, increased follow-up compliance across intervention studies. Inconsistent evidence for associations among race, income, and age were found.
Conclusions: Further research is needed to reinforce current studies addressing health beliefs and social support. Interventions that focus on the interplay among psychological, educational, and communication barriers are necessary. These interventions should be adapted and applied across various racial/ethnic and socioeconomic groups to reach all women with a high-risk profile for invasive cervical cancer
Volatile Compounds Produced by Irradiation of Commercial Hams and Frankfurters
Low-dose irradiation (1.6 kGy) of commercially- produced cured, sliced ham and frankfurters resulted in off-odors and off-flavors following the irradiation treatment. Lipid oxidation was not affected by irradiation but gas chromatography/mass spectrometry analysis showed that several new volatile compounds were produced in the products by irradiation processing. These included heptane, trans-1-butyl-2- methylcyclopropanone, 2-octene toluene and 2- butanone. Changes in odor and flavor of irradiated ham and frankfurters resulting from production of volatile compounds must be controlled before irradiation will be accepted by the industry or by consumers as a means of improved the microbial safety of these products
TIAF1 self-aggregation in peritumor capsule formation, spontaneous activation of SMAD-responsive promoter in p53-deficient environment, and cell death
Self-aggregation of transforming growth factor β (TGF-β)1-induced antiapoptotic factor (TIAF1) is known in the nondemented human hippocampus, and the aggregating process may lead to generation of amyloid β (Aβ) for causing neurodegeneration. Here, we determined that overexpressed TIAF1 exhibits as aggregates together with Smad4 and Aβ in the cancer stroma and peritumor capsules of solid tumors. Also, TIAF1/Aβ aggregates are shown on the interface between brain neural cells and the metastatic cancer cell mass. TIAF1 is upregulated in developing tumors, but may disappear in established metastatic cancer cells. Growing neuroblastoma cells on the extracellular matrices from other cancer cell types induced production of aggregated TIAF1 and Aβ. In vitro induction of TIAF1 self-association upregulated the expression of tumor suppressors Smad4 and WW domain-containing oxidoreductase (WOX1 or WWOX), and WOX1 in turn increased the TIAF1 expression. TIAF1/Smad4 interaction further enhanced Aβ formation. TIAF1 is known to suppress SMAD-regulated promoter activation. Intriguingly, without p53, self-aggregating TIAF1 spontaneously activated the SMAD-regulated promoter. TIAF1 was essential for p53-, WOX1- and dominant-negative JNK1-induced cell death. TIAF1, p53 and WOX1 acted synergistically in suppressing anchorage-independent growth, blocking cell migration and causing apoptosis. Together, TIAF1 shows an aggregation-dependent control of tumor progression and metastasis, and regulation of cell death
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
