Reactions With Platinum (Ll) Complexes And Selenium-Containing Amino Acids, Stephanie Robey
Mahurin Honors College Capstone Experience/Thesis Projects
We have reacted [Pt(Me4en)(D2O)2]2+ [Me4En=N,N,N’N’-tetramethylethylenediamine] with Selenomethionine (SeMet), Methionine (Met), and Methylselenocysteine (MeSeCys). When MeSeCys was reacted with [Pt(Me4en)(D2O)2]2+, we observed both stereoisomers of Se,N chelates, as well as [Pt(Me4en)(MeSeCys)Cl]+ from 1H NMR Spectroscopy; the latter formed due to the presence of Cl- in the solution. Both isomers of the chelate seemed to form proportionally to one another, not favoring a specific stereoisomer. Eventually the [Pt(Me4en)(MeSeCys)Cl]+ products became Se,N chelates. We incubated SeMet with …
Sound Production In Two Loricariid Catfishes, Amanda Lynn Webb
Sound Production In Two Loricariid Catfishes, Amanda Lynn Webb
Masters Theses & Specialist Projects
Many families of catfish produce sounds via pectoral spine stridulation and/or swim bladder compression using sonic muscles attached to the swim bladder. The sound production capabilities and characteristics in Loricariidae, the largest catfish family, have not been well examined. Sounds produced by two loricariid catfish species, Macrotocinclus affinis and Pterygoplichthys gibbiceps were recorded. Both species produce broad band calls via pectoral spine stridulation. These species produce sounds by rubbing the ridges of the dorsal process of the pectoral spine base against the groove of the pectoral girdle. Call duration was generally shorter in M. affinis (2-15 ms) as opposed to …
Pcr Amplification Of Trypanosoma Cruzi - Specific Dna From Raccoon Blood Samples, Colin Moss
Pcr Amplification Of Trypanosoma Cruzi - Specific Dna From Raccoon Blood Samples, Colin Moss
Mahurin Honors College Capstone Experience/Thesis Projects
The parasitic protist Trypanosoma cruzi is the causative agent of Chagas Disease. Chagas Disease causes greater than 15,000 deaths each year, and nearly 28 million people are believed to be at risk of infection in Central and South America. This parasite has been described in many mammalian host species and has also been described in the United States. The purpose of this study was to attempt to use PCR to amplify T. cruzi-specific DNA directly from blood samples obtained from raccoons (Procyon lotor) trapped in Warren and Barren Counties of Kentucky in 2007 and 2008. DNA was …
