The Effects Of Methamphetamine Exposure On Cardiovascular Development In Combination With Hypoxia In Danio Rerio, Sarah Donaldson
The Effects Of Methamphetamine Exposure On Cardiovascular Development In Combination With Hypoxia In Danio Rerio, Sarah Donaldson
Williams Honors College, Honors Research Projects
The purpose of this study was to determine the effects of methamphetamine combined with hypoxia on the development and function of the cardiovascular system in Danio rerio embryos. It was hypothesized that the combined effect of the drug and decreased oxygen concentration would result in decreased cardiac parameters due to underdevelopment of the ventricle and vessels resulting from cardiomyopathy and lack of blood flow to tissues. It was found that methamphetamine exposure correlated to an increase in stroke volume, caudal artery and vein diameters and RBC velocities alone, while having a multiplicative effect of increasing arterial RBC velocity when combined …

Measuring Bacterial Growth Using A 3d-Printable Spectrometer, Samuel R. Bunting
Williams Honors College, Honors Research Projects
Visible light spectroscopy is a commonly used technique for measuring the growth of bacterial cultures, and growth curves provide broadly important data. However, the equipment and resources required for these experiments has been restricted to higher education and industry due to high cost and sophistication. We have previously reported on an inexpensive, 3D-printable photospectrometer called the SpecPhone. This device utilizes an iPhone as the camera, along with several other, inexpensive additions to make a fully functional spectrometer. Here, the application of the SpecPhone is expanded to the quantification of actively dividing E. coli cultures. Two protocols have been developed; one …
