Functional Implications Of Nlrp1 Variants For Autoimmune Disease, Laura J. Westhoff
Functional Implications Of Nlrp1 Variants For Autoimmune Disease, Laura J. Westhoff
Undergraduate Honors Theses
NLRP1 is a protein-coding human gene that plays a crucial role in the NLRP1 inflammasome. Variants to the NLRP1 gene have been associated with autoimmune and autoinflammatory diseases. We examined the effects of polymorphisms at two SNPs on cytokine levels and NLRP1 gene expression in 50 human volunteers without diagnosed autoimmune disease. NLRP1 was genotyped at SNPs rs2670660 and rs12150220 and individuals who were homozygous at one or more SNP were selected for further analysis. Serum IL-18 and IL-1β levels were quantified using ELISA. NLRP1 gene expression was measured using real-time PCR. A strong linkage was found between genotypes of …
Improving And Modeling Bacteria Recovery In Hollow Disk System, Clifton Anderson
Improving And Modeling Bacteria Recovery In Hollow Disk System, Clifton Anderson
Theses and Dissertations
Identifying antibiotic resistance in blood infections requires separating bacteria from whole blood. A hollow spinning disk rapidly removes suspended red blood cells by leveraging hydrodynamic differences between bacteria and whole blood components in a centrifugal field. Once the red cells are removed, the supernatant plasma which contains bacteria is collected for downstream antibiotic testing. This work improves upon previous work by modifying the disk design to maximize fractional plasma recovery and minimize fractional red cell recovery. V-shaped channels induce plasma flow and increase fractional plasma recovery. Additionally, diluting a blood sample spiked with bacteria prior to spinning it increased the …
You Are What You Eat At Any Age: Carbon And Nitrogen Analysis Of Mummies From An Ancient Egyptian Necropolis, Stephen Funk, R. Paul Evans
You Are What You Eat At Any Age: Carbon And Nitrogen Analysis Of Mummies From An Ancient Egyptian Necropolis, Stephen Funk, R. Paul Evans
Library/Life Sciences Undergraduate Poster Competition 2019
The BYU Egypt Project at Fag el-Gamus necropolis and adjacent Seila Pyramid has studied over 700 mummies excavated over the past 30 years. The necropolis includes an open area with densely located vertical burial shafts and a hill with horizontal burial shafts. The chronological and dietary history of the mummies was assessed using stable isotopy and 14C analysis of accessible biological samples.
Further Understanding Of Bacteriophages That Infect The Bacterial Family Enterobacteriaceae, Paul Flake
Further Understanding Of Bacteriophages That Infect The Bacterial Family Enterobacteriaceae, Paul Flake
Undergraduate Honors Theses
Despite the eclectic nature of bacteriophage genomes, nucleotide comparison is an effective method for grouping phages into cluster and subcluster classifications. This process is facilitated by making preliminary cluster assignations based on the identity of the major capsid protein. As more phages continue to be sequenced and integrated into cluster/subcluster groupings, adjustments may need to be made to the genomic similarity percentages that have previously defined cluster/subcluster classifications. Implementing proteomic comparison in addition to nucleotide homology may provide added clarity to this process. Protein conservation and diversity among lytic phages that infect the bacterial family Enterobacteriaceae is discussed and the …

Pas Kinase And Tor, Controllers Of Cell Growth And Proliferation, Brooke Jasmyn Cozzens
Theses and Dissertations
Nutrient sensing kinases lie at the heart of cellular health and homeostasis, allowing cells to quickly adapt to changing environments. Target of Rapamycin (TOR) and PAS kinase (PASK, or PASKIN) are two such nutrient kinases, conserved from yeast to man. In yeast, these kinases each have paralogs. The two TOR paralogs in yeast mimic the mammalian TORC1 and TORC2 complexes, except both Tor1 and Tor2 may contribute to TORC1 or TORC2 function. The two PAS kinase paralogs are paired with the TOR paralogs, meaning that both Psk1 and Psk2 regulate TORC1, while Psk2 suppresses a temperature-sensitive allele of Tor2. Herein …
