Background Although pancreatic cancer incidence is low at 13.1 per 100,000 people, this cancer is difficult to treat and carries a poor 5-year survival rate. Additionally, pancreatic cancer survival rates vary disproportionately based on age and race. The objective of this study was to evaluate the association between 5-year survival of pancreatic cancer and the basic demographic factors age, race, and sex. Methods Data were retrieved from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) 18 database, spanning from 2000-2017, using SEER*Stat. SPSS was used to calculate descriptive statistics for vital status, age, race, and sex. Odds ratios with confidence intervals were calculated using Epi Info. Case data were used to conduct survival analysis by age, race, and sex using OriginPro. Results Out of a total of 118,581 cases, 79.3% were White (n = 106,887), 12.5% were Black (n = 16,866), 7.4% were Asian or Pacific Islander (n = 9,960), 0.6% were American Indian/Alaskan Native (n = 792), and 0.2% were unknown race (n = 321). The odds ratio (OR) of dying before reaching 5+ survival was lowest for the Asian or Pacific Islander group (OR = 0.70, 95% CI: 0.66 - 0.74), followed by the group of Black patients (OR = 1.07, 95% CI: 1.02 - 1.13), the White patients group (OR = 1.12, 95% CI: 1.08 - 1.17), and the American Indian/Alaskan Native group (OR = 1.12, 95% CI: 0.89 - 1.40). The largest age group was 65-69 years old, comprising 14.7% (n = 19,866) of the dataset. Probability of 5+ year survival for pancreatic cancer patients was highest for the age group 15-19 years (n = 74). In general, 5+ year survival probability declined with age. Risk of death before reaching 5+ year pancreatic cancer survival was slightly higher in men (OR = 1.03, 95% CI: 1.00 - 1.07), who comprised 50.9% (n = 68,628) of the dataset. Discussion Findings from this study corroborate differences by age, race, and sex discussed in the literature. Differences in survival rates by race depart from some findings in literature documenting no significant differences in treatment outcome by race. Controlling for age in a future study in both race and sex survival probability analyses may be helpful. Further, stratifying by sex in survival probability analysis by race would be illuminating. In addition to survival analysis, regression modeling would be a useful next step.

The Psychrometric Testing Facility at the Riverside Energy Efficiency Laboratory at Texas AandM University has not been operational for several years. The goal of this project was to restore the testing facility to a fully operational condition for the purpose of supporting research and cooling capacity testing, with the latter following the appropriate standards. Numerous changes were made to the coolant piping system, the data acquisition system, instrumentation, and temperature and humidity control to update and improve the facility. In addition, a computer program was developed and implemented that allows for flexible control of the facility’s conditions and collection of data while showing real time performance and refrigerant and psychrometric calculations. The current program flexibility, along with the proper combination of instrumentation, allows the Psychrometric Facility to operate with separate steady state environmental conditions in each room, according to, and meeting, the AHRI 210/240 standard. Cooling capacity testing done on a split system residential unit was compared to the published AHRI rating to benchmark the state of the facility. Tested cooling capacity was about 3 percent below the published cooling capacity; tested EER was about 7 percent below the published EER; and finally, the calculated SEER based on the default degradation coefficient was about 10 percent below the published SEER. The difference in the calculated performance parameters to the published are expected due to unknown testing conditions used to calculate the published rating.

This study fills a gap in previous research concerning the portrayal of Peter in Matthew, especially the research of narrative-critical studies. Although narrative-critical studies generally recognize that Matthew has portrayed Peter and the disciples as recipients of revelation at points, they almost entirely neglect the apocalypses or apocalyptic literature more broadly as a potentially helpful background for this motif, nor does the motif itself figure significantly into their conclusions. Therefore, Part 1 of this study examines fourteen different Jewish and Christian apocalypses in order to determine generic aspects of how the apocalypses portray their seers, and to identify specific textual features that support these generic aspects of a seer’s portrayal. These specific textual features then provide the guiding coordinates for Part 2, which assesses the influence of the generic portrayal of apocalyptic seers on the portrayal of Peter and the disciples in Matthew’s Gospel and main source, Mark’s Gospel. Like the apocalypses, both Evangelists deploy the features of exclusionary statements, narrative isolation, dissemination details, and emphasis of cognitive humanity and emotional-physical humanity to portray Peter and the disciples as the exclusive recipients of revealed mysteries, and as humans who encounter the mysteries of the divine realm. This leads to the conclusion that both Evangelists envisaged Peter and the disciples as apocalyptic seers in some sense. However, Matthew’s redaction of Markan source material, incorporation of Q source material, and his own special material yield a more fully developed, or more explicit, portrayal of Peter and the disciples as apocalyptic seers than his Markan predecessor. The study concludes by focusing directly on Peter’s significance for Matthew and his earliest audience. The research suggests that Peter’s significance was, in part, as principal apocalyptic seer, which requires revision to the predominant scholarly conclusions about Peter in Matthew.

Breast cancer is one of the most prevalent forms of cancer in the world today. The search for effective treatment and screening methods is a highly active area of research. The Digital Image-based ElastoTomography (DIET) project is a new breast cancer screening system under development, where surface motion from the mechanically actuated breast is measured in 3D, and used as input to an inverse problem solving for breast elasticity. Cancerous lesions appear as high contrast features, being an order of magnitude stiffer than healthy tissue. The 3D motion capture is measured by an array of digital cameras using computer vision techniques. This thesis presents a complete imaging system and algorithms for the capture of 3D breast surface motion. The main components of the 3D motion capture system are the hardware and software image capture system, camera calibration, intra-image feature tracking, and 3D surface and motion reconstruction. Accurate algorithms for each of these components are developed, with a view to future development and potential modifications needed for a clinically-appropriate system. A number of the algorithms developed have potential applications outside of the DIET system. Proof of concept studies demonstrate the viability of the system, with full motion reconstruction being performed on silicone gel phantoms, designed to approximate human soft tissue, in a number of laboratory experiments.

Purpose Our objectives were to 1) determine the difference in Rhabdomyosarcoma (RMS) incidence and survival between different race/ethnicity groups, and 2) evaluate the difference in survival of RMS between children and adults of these race/ethnicity groups, using the Surveillance, Epidemiology, and End Results Program (SEER) database between 1973-2013. Patients and Methods We analyzed racial characteristic and incidence data from 4,280 patients diagnosed with RMS, between 1973-2013, that were reported to the SEER database. Survival and hazard analyses were conducted on 4,268 patients with known follow-up data, with end point being death from any cause. Results Over the 40-year study period overall RMS incidence rates have experienced a statistically significant decline (APC: -0.78, 95% CI: -1.28 – -0.28). Whites have experienced a significant decline in incidence rates (APC: -1.05, 95% CI: -1.60 – -0.50). Though not statistically significant, incidence rates in Blacks and Hispanics have trended upwards. While adjusted survival was not predicted by race, survival did significantly differ among racial/ethnic groups in children, with Hispanics and “Others” having the lowest 5- and 10-year survival rates (65% and 58% verses 58% and 56%, respectively). Black race/ethnicity was also shown to be a predictor for mortality for the time period 1990-2013. Conclusion Racial/ethnic minorities have worse RMS clinical presentation and incidence rates than Whites. While overall survival is not predicted by race, being an ethnic minority child diagnosed with RMS is predictive of survival. These disparities point towards a genetic component in RMS that has not yet been described.

Introduction Lung cancer is the most common cause of cancer-related death in the United States (US). Tobacco smoking is a well-recognized cause of lung cancer. About 2% of the United States (US) population lives in Tennessee (TN). Nearly 21 % of TN adults are current smokers as per 2019 data, compared to 14% across the US. The percentage of smokers has historically been high in TN and its surroundings. This can be attributed to the area's socio-economic and cultural characteristics, along with large areas of tobacco farming in the region. This increases the risk of lung cancer in the TN population. Surveillance Epidemiology and End Results Program (SEER) is a collection of cancer registries across the US, covering about 35% of the US population (TN cancer registry is not a part of SEER). Our study compares lung cancer incidence and characteristics in the TN cancer registry with the SEER 18 registry. Materials and Methods Data were collected from the TN cancer registry and SEER separately for lung and bronchial cancer. Data was analyzed for different histological subtypes, age groups, gender, stage at diagnosis, and rural/urban residence. Stata and Microsoft Excel were used in data analysis. A Chi-square test was used to calculate the statistical significance. Results From 2008 to 2017, 58644 cases of lung cancer were reported in the Tennessee cancer registry. During the same period, 519112 cases were reported in the SEER registry. The most frequent histological subtype of lung cancer in TN and SEER was adenocarcinoma (frequency of 17,503 Vs. 182346), followed by squamous cell carcinoma and small cell carcinoma. Most cancers in TN and SEER were diagnosed at stage of distant metastasis (46% vs. 52% ), followed by regional metastasis, localized, and in situ (Image1). The frequency of lung cancer diagnosis was high among those older than 65 in TN and SEER (64% vs. 69%). Males had a higher incidence of lung cancer in both registries. Most lung cancers were reported in the urban area in both registries. Chronic obstructive pulmonary disease was the most commonly reported secondary diagnosis (3,099), followed by pleural effusion in the TN database; the comparable data were not available in SEER. Relative survival at 12 months and five years for lung cancer in TN were 46.6 % and 19.5 % (Vs. 46.4% and 19.9% in SEER) Discussion and Conclusion If both registries were perfect, then lung and bronchial cancer incidence will be 9241 and 6048 per million in ten years in TN and SEER, respectively. But after careful analysis, we conclude that such analysis will be erroneous. The proportion of different histological types, stage at diagnosis, age groups, and gender were in the same order in both groups. Although chi-square test values are significant for all the variables, we infer no conclusion considering the data's inherent bias. Further in-depth analysis of the data is required.

RASSF1A is a tumor suppressor gene which loses its function due to methylation of CpG islands on its promoter region. Detection of methylation leads to early diagnosis of cancer. Zinc finger proteins are capable of detecting a specific DNA sequence and Methyl binding domain can bind to the methyl group on the CpG, using this idea mCpG SEER- Lac system makes use of a split protein, β-lactamase. Lac A attached to the ZFP and Lac B attached to the MBD protein. On binding to the DNA, the Lac A and Lac B come in close proximity with each other causing a reassembly and activation of the enzyme. In the presence of a substrate, the activated β-lactamse enzyme hydrolyzes the β-lactam bond in the substrate and shows a color change from yellow to red in the presence of a methylated cognate DNA. The study suggests that a solution based assay was not as specific in differentiating signal intensities between methylated and non-methylated DNA. It was also not sensitive in measuring dose dependent signals. Zinc finger array could successfully show relatively low signals for non-methylated DNA. The findings of the study show that MBD2 shows higher preference for mCpG than MBD1 in the mCpG SEER-Lac system and oligonucleotides with a 2 bp spacing between methylation and ZF target site shows higher signals than the 3 bp spacing. Due to it’s specificity and sensitivity, it serves as a potential diagnostic tool to detect cancer.

Multiple research studies have demonstrated racial, socioeconomic status (SES), and neighborhood disparities in first-line treatment of colorectal cancer patients, including those with metastatic colorectal cancer. However, disparities in adjunct monoclonal antibody treatment disparities have not been explored. The purpose of this study was to assess racial, SES, and neighborhood disparities in adjunct monoclonal antibody treatment of elderly metastatic colorectal cancer patients. The research was rooted in 3 theories: the fundamental cause theory, the diffusion of innovations theory, and theory of health disparities and medical technology. Data from the SEER-Medicare database and logistic regression were used to assess the relationship between the variables of interest and adjunct monoclonal antibody therapy. In this study, race (p = 0.070), SES (p = 0.881), and neighborhood characteristics (p = 0.309) did not significantly predict who would receive monoclonal antibody therapy. The results demonstrated a potential improvement in historically documented colorectal cancer treatment disparities. Specifically, historical treatment disparities may not be relevant to newer therapies prescribed to patients with severe disease. The difference could be related to improved access to care or a change in treatment paradigm due to the severity of metastatic colorectal cancer. Future studies aimed at understanding the causes of this social change (i.e., reduced treatment disparities) are warranted. Understanding the root cause of the reduced treatment disparities observed in this study could be used to reduce treatment disparities in other cancer populations.

Joseph Smith Junior, founder of the Mormon faith, presented himself to America and the world as a prophet with the same powers as the widely known prophetic figures of the Bible. Like Moses and Elijah, he made God's will known to humankind. Before assuming this role, Smith had used divining rods and then seer stones to find underground water, buried treasure, lost items, and stray livestock. This thesis charts Joseph Smith's progression from rodsman to seer to prophet. For the most part, I present Joseph Smith's divinatory development as he himself experienced it. Dowsing with a rod, seeing things in stones, and receiving heavenly revelations were as real to Smith as harvesting wheat. In order to understand his progression from rodsman to seer to prophet, one must first understand his worldview. The mental universe of early American water witches and village seers forms one of the historical and cultural contexts in which Joseph Smith developed his divinatory abilities.
