Unraveling The Mummy: The Effects Of Natural Mummification On The Recovery And Degradation Of Dna, Marissa Gandolfo-Muller

Honors Theses

As demonstrated through casework and research studies (Hawass et al., 2010; Gielda & Rigg, 2017), anthropogenic mummification and modern-day embalming can expedite degradation of DNA. Current research in the field of forensic mummification is sparse and little research has been done on quantifying naturally mummified DNA (Leccia et al., 2018; Shved et al., 2014). This research focuses on observing and quantifying the differences in the recovery and degradation of DNA from specimens that have been naturally mummified. This research on natural, forensic mummies is a blend of experimental archeology and postmortem DNA analysis.

Study Of The Role Of The Msaabcr Operon In Tricarboxylic Acid Cycle Activity And Persister Cell Formation In Staphylococcus Aureus, Karsen Motter

Honors Theses

Staphylococcus aureus is an important human pathogen that causes wide arrays of infections ranging from minor skin infections to lethal systemic conditions such as infective endocarditis, osteomyelitis, sepsis and pneumonia. These systemic diseases are often difficult to treat due to the presence of persister cells. Persister cells are a phenotypic variant of the bacterial population that exhibit extreme and transient antibiotic tolerance accompanied by a transient halt in growth. Upon cessation of antibiotic treatment, however, persisters resume growth which results in recurrence of infections. This characteristic of persister cells therefore displays high clinical significance. In this study, we show the …

The Diversity And Evolution Of Phenazine Biosynthesis Pathways In Enterobacterales, Christian Leise

Honors Theses

Enterobacterales is an order of Gram-negative bacteria that encompasses plant and animal pathogens and organisms of industrial importance. Some of these bacteria produce secondary metabolites classified as phenazines (Phz). Studies in other groups of microorganisms revealed that phenazines are redox-active and exhibit broad antibacterial, antifungal, and antiparasitic activity. Enterobacterales are known to produce phenazines, but details about the diversity, biochemistry, and function of phenazine metabolites in these organisms are missing. In this work, we screened the National Center for Biotechnology Information (NCBI) GenBank for genome sequences of phenazine-producing (Phz+) Enterobacterales. Additionally, genomes of Phz+ strains Pectobacterium carotovorum cc303 and …

Framing Race: An Analysis Of Media Coverage Of The Racially Motivated Murders Of Emmett Till And Trayvon Martin, Chloe Jackson

Honors Theses

In August 1955, Emmett Till, a 14-year-old Black boy from Chicago, was brutally murdered by two white men for “wolf whistling” at a white woman. Fifty-seven years later, 17-year-old Trayvon Martin was shot and killed by a neighborhood watchman on February 26, 2012. The unwarranted killings of these two Black boys caused uproars across the entire country. This study examines how the media framed and represented Till and Martin in the cases of their racially motivated murders. Prior research shows that Black male youth are framed in the media as deviant and lawless, continuously being represented as criminals. However, there …
