Lutein and zeaxanthin are two important carotenoid vitamins related to ocular health and human visual processing. These vitamins can be ingested through supplementation and in regular diet. They concentrate in the central retina where they form a filter of macular pigment and protect the eye from high energy blue and yellow light. We examined participants who had a natural diet of high vs low lutein and zeaxanthin intake on tests of contrast sensitivity and glare disability. We also examined participant performance while wearing blue light blocking glasses in order to determine whether these glasses serve a similar protective function as macular pigment in benefiting participants on contrast sensitivity and glare disability tasks. Most of our data did not show statistically significant differences between the high and low lutein and zeaxanthin groups. An unexpected result that the blue blocker glasses hindered the ability of low lutein participants on their glare disability test was observed. We hypothesize that this is due to light scatter produced by the by glasses resulting in an impoverish retinal image reaching the primary visual cortex. Further research is required to examine this new finding.

Breast cancer affects about 12% of women in the US. Arguably, it is one of the most advertised cancers. Mammography became a popular tool of breast cancer screening in the 1970s, and patient-geared guidelines came from the American Cancer Society (ACS) and the US Preventative Task Force (USPSTF).

Breast cancer affects about 12% of women in the US. Arguably, it is one of the most advertised cancers. Mammography became a popular tool of breast cancer screening in the 1970s, and patient-geared guidelines came from the American Cancer Society (ACS) and the US Preventative Task Force (USPSTF). This research focuses on ACS guidelines, as they were the earliest as well as the most changed guidelines. Mammography guidelines changed over time due to multiple factors. This research has tracked possible causes of those changes. Research began with an extensive literature search of clinical trials, the New York Times and the Washington Post archives, systematic reviews, ACS and USPSTF archives.

Description

Science fiction works can reflect the relationship between science and society by telling stories that are set in the future of ethical implications or social consequences of scientific advancements. This thesis investigates how the concept of reproduction is depicted in popular science fiction works.

By questioning methods of sex selection since their early development, and often discovering that they are unreliable, scientists have increased the creative and technological capacity of the field of reproductive health. The presentation of these methods to the public, via published books on timing methods and company websites for sperm sorting, increased interest in, and influence of, sex selection within the global society. The purpose of explaining the history, interest, development, and impact of various sex selection methods in the mid-twentieth century based on the information that is available on them today is to show couples which methods have failed and provide them with the knowledge necessary to make an informed decision on how they choose to go about utilizing methods of sex selection.

By demonstrating the struggle for sound standard of care for non-medical reproductive health care providers during the nineteenth and early twentieth century, this project emphasizes what the standards of reproductive health care for abortion and contraception might be like if the organizations that made them so readily available, like Planned Parenthood, were defunded or criminalized in our modern setting.
