Autophagy is a process that generates the necessary building components for cells by cytoplasmic breakdown of unnecessary materials (Martin, Celano, Solitro, Gunaydin, Scott, et. al., 2018). This is a survival technique for cells in times of stress, especially during periods of nutrient starvation. Cancer cells, unfortunately, benefit from this process due to their ability to flourish in nutrient-starved environments, becoming resistant to therapy. The primary protein in mammals responsible for this process is a serine/threonine kinase called ULK 1 (unc-51 like autophagy initiating kinase 1). As such, inhibitors of ULK 1 can be used in cancer therapies in order to …
Quantification Of Vitamin B12 In Two Cricket Species, Haley Smeltz
Quantification Of Vitamin B12 In Two Cricket Species, Haley Smeltz
Student Scholar Showcase
Entomophagy, or the eating of insects, has been practiced in the eastern world for centuries, however it is currently overlooked in the western nations. Studies have shown that insects, such as crickets, contain high levels of protein and minerals, however vitamin content is rarely studied. This study aims to quantify the vitamin B12 content in two cricket species, the common house cricket (Acheta domesticus) and the banded cricket (Gryllodes sigillatus). The vitamin B12 content of both cricket species will be quantified using reverse-phase high performance liquid chromatography (RP-HPLC). Prior to RP-HPLC analysis, all the …

Design, Construction, And Characterization Of A Low-Cost Spectrometer With Interchangeable Parts, Jack Godek
UNO Student Research and Creative Activity Fair
A low-cost spectrometer was designed for the purpose of teaching spectroscopy. The spectrometer can be built by the student and contains interchangeable pieces such as slit width, grating, and lenses. This will allow the student to understand how changing these variables effects resolution. The spectrometer was constructed from PVC pipe, a plastic electrical box, and a USB webcam. The actual resolution of the spectrometer is close to the theoretical value, depending on which lens and grating is used. In addition, an extra piece can be added that allows absorption spectra to be collected. Having the student piece together the spectrometer …
