Pence-Boyce STEM Student Scholarship
The human body has natural systems for vasodilation which are fueled by nitric oxide production, but in cases of cardiac disfunction and stress nitric oxide can be inhibited. In this study, nitric oxide was studied as a mediator for the blood rush experienced from the warming after induced hypothermia. Nitric oxide (NO) was introduced through sodium nitrate, which was aimed to reduce the speed and turbulence of blood flow through interaction between NO and the active site of hemoglobin. A viscometer was used to examine the rate of blood flow, while the temperature was varied to simulate the conditions of …

Hexavalent chromium, or Cr(VI), is a potent oxidizer and known carcinogen, that is found at varying levels in the water sources of more than 200 million Americans. However, the exact mechanism of carcinogenicity remains unknown, and though the government currently regulates total chromium levels, they have yet to determine a permissible exposure limit for Cr(VI). Moreover, there is currently no preventative treatment for Cr(VI). Because of Cr(VI)’s strong oxidative power, we hypothesized that it causes DNA mutation and cell death via oxidation and that antioxidants could prevent this from occurring. To test this, we first assessed the viability of human …
