Melanoma is the deadliest form of skin cancer, arising from malignant transformation of pigment-producing melanocytes. The primary risk factor for melanoma and other skin cancers is DNA damage resulting from unprotected solar ultraviolet radiation (UVR). If incorrectly repaired, this damage can result in incorporation of mutations that cause aberrant cell...
The purpose of this study was to compare the levels of bone
mineral density (BMD) of the whole body (WB) and proximal
femurs of physically active men with spinal cord injuries (SCI) to
nonactive men with spinal cord injuries. Also, the lean muscle
mass (LMM) of active men with SCI...
Postmenopausat women on hormone replacement therapy (HRT) have been reported to be stronger when compared to women who are not using HRT. The first goal of this study was to investigate whether muscle morphology was altered in women who use HRT when compared to women who do not use HAT....
Studies in young women show that rowing exercise is osteogenic at the spine. However, little is known regarding rowing exercise and spine bone mineral density in older women. The aim of this study was to examine differences in spine bone mineral density (BMD) and back strength between premenopausal and postmenopausal...
Women are economically disadvantaged in most U.S. labor markets, demonstrated by a persistent gender wage gap. The relative wage discrepancy can be understood as a result of labor market conditions, human capital investments, and gender discrimination. To determine if the wage gap could be decreased, I use classical regression modeling...
The removal of microbial populations from potable water has been a practice with great importance towards public health, as it has resulted in the reduction of literally millions of cases of infectious disease. In the United States, pathogenic organisms are most commonly removed from drinking water through the application of...
Numerous dietary factors have been shown to influence the fatty acid profiles (FAP)
in breast milk from lactating women. However, few studies have evaluated the effect of trace
minerals on milk FAP. Consequently, the purpose of this study was to determine the effect
of selenium status on the FAP in...
The seasonal distribution of bioavailable organochiorine contaminants in surface
water and the potential environmental factors influencing their bioavailability were
evaluated. The study was carried at the lower Willamette River at Portland Harbor, Oregon
where surface water runoff varied according to season. Bioavailable water concentrations of
DDTs and PCBs were determined...
The 100 North Pacific rockfish species in the genus Sebastes are highly diverse. Rockfishes fertilize their eggs internally and release swimming larvae. Complex courting behaviors may allow female rockfish to be selective about their mates and may promote and maintain speciation. In this study, I applied genetic techniques to survey...
