Potential Cellular Mechanisms Of Estrogen's Effects On Maintaining Sperm Production In Aging Rats, Matthew Pate
Potential Cellular Mechanisms Of Estrogen's Effects On Maintaining Sperm Production In Aging Rats, Matthew Pate
Honors Theses
Testosterone production by Leydig cells declines during aging in both men and rodent models. Previous results from our lab demonstrated that daily sperm production also declines in aging rats and alterations in the estrogen environment of the testis contribute to this decline. Importantly, estrogen treatment during aging was able to attenuate the age-associated decline in sperm production. However, the cellular and molecular mechanisms by which estrogen maintains sperm production remain unclear. These experiments were designed to further investigate the effects of estrogen on sperm production in an attempt to further define the cellular mechanisms regulated by estrogen within the testis. …

Family Planning, Pregnancy, And Birth In Guatemala: Maya Women And Modern Healthcare, Kelsay Payton
Honors Theses
Within Maya populations in rural Guatemala, childbearing is considered a sacred and spiritual experience, in addition to a physical one. This country is home to some of the highest rates of maternal and infant mortality in Latin America, along with the largest disparities in health care, primarily between the indigenous Maya and ladino women (Schooley 2009). The use of biomedical reproductive services remains surprisingly low among the Maya, while it is continually rising in the ladino populations. To increase the overall reproductive health care in these indigenous communities, attention must be given to the understanding of Maya’s beliefs, therefore enabling …
The Historical Evolution Of Endoscopy, Sarah Ellison
The Historical Evolution Of Endoscopy, Sarah Ellison
Honors Theses
INTRODUCTION: Minimally invasive surgery is on the rise and is becoming more common. Its advantage over traditional open surgery is a quicker recovery time and minimized risk of infection along with an aesthetically more pleasing smaller scar. Although many different scopes and instruments perform minimally invasive techniques, all minimally invasive instruments evolved from endoscopy. It wasn’t until the 20th century that they began to diverge to separate studies. Therefore endoscopy is considered in regards to instrument evolution. History is full of twists and turns as different pieces of the scope progressed so its advancement has been separated into the …
