Assessment Of Her2-Neu In Breast Cancer Lines Upon Differential Exposures To Xenoestrogens, Abha Aggarwal
Assessment Of Her2-Neu In Breast Cancer Lines Upon Differential Exposures To Xenoestrogens, Abha Aggarwal
Walden Dissertations and Doctoral Studies
Synthetic xenoestrogens have differential estrogenic properties. Research has shown that exposures to xenoestrogens could promote breast cancer by disrupting normal function of the human epidermal growth factor receptor 2 (Her2) gene. Although animal models demonstrated a connection between xenoestrogen exposure and Her2 activity, no study using human cells has systematically examined their carcinogenic potential influencing the Her2 gene expression. Furthermore, breast cancer cells are phenotypically disparate (ER+, Her2+), with some phenotypes (Her2+), leading to more aggressive disease. This study aimed to dosimetrically assess the carcinogenic potential of commonly used xenoestrogens influencing Her2 gene expression, and delineate cellular phenotypes at greater …
Perceptions Of Emergency Preparedness Among Immigrant Hispanics Living In Oklahoma City, Oklahoma, Rebekah Doyle
Perceptions Of Emergency Preparedness Among Immigrant Hispanics Living In Oklahoma City, Oklahoma, Rebekah Doyle
Walden Dissertations and Doctoral Studies
Tornadoes are occurring with increased frequency in Oklahoma. Emergency preparedness planning is essential to decreasing individuals' risks of injury or death from a tornado. Research on immigrant Hispanics' knowledge and perceptions of emergency preparedness is limited. The purpose of this study was to explore the perceptions and lived experiences of immigrant Hispanics who had experienced a tornado or other crisis weather conditions in Oklahoma during spring of 2013. The research questions explored their perceived risk for injury and knowledge of tornado preparedness planning. The health belief model provided the theoretical underpinnings for this qualitative phenomenological study. Semi structured interviews were …
Drinking Water And Autism: Using Spatial Cluster Detection To Explore Patterns Of Autism Cases In Lane County, Oregon, Sherry Sandreth
Drinking Water And Autism: Using Spatial Cluster Detection To Explore Patterns Of Autism Cases In Lane County, Oregon, Sherry Sandreth
Walden Dissertations and Doctoral Studies
Autism Spectrum Disorders (ASD) are a complex array of neurological disorders with a diverse presentation, multiple etiologies, and long-term ramifications. Prevalence of ASD in the United States is about 1 in 50 children as of 2013, making it a significant public health problem. The etiology is not understood, and it is widely accepted that it is multicausal, with genetic and environmental influences. Prior research suggests an association between water source and ASD. Contaminants such as lead, arsenic, mercury, pharmaceuticals and pesticides found in water are associated with developmental disorders suggesting that a systematic review focused on water source was warranted. …
Methylmercury Exposure Via Canned Tuna Fish Consumption And Breast Cancer, Jennifer Bodenrader
Methylmercury Exposure Via Canned Tuna Fish Consumption And Breast Cancer, Jennifer Bodenrader
Walden Dissertations and Doctoral Studies
Widespread consumption of canned tuna fish since the 1950s may explain some of the increase in breast cancer prevalence in the United States and Europe. Although canned tuna is the primary source of human exposure to methylmercury, its role as an estrogen activating metalloestrogen has been overlooked in the etiology and incidence of breast cancer. Carcinogenic theory asserts that increased exposure to estrogen elevates the risk of breast cancer. The purpose of this population-based, case control study was to examine the association between canned tuna consumption, total blood mercury, and breast cancer in the NHANES 2003-2006 surveys. A multivariable logistic …
