Effect Of Temperature On The Microbiome Of A Laboratory Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna Mitchell

Poster Presentations

Honors research poster.

Haemaphysalis longicornis is a species of tick native to eastern Asia, including eastern China, Japan, eastern Russia, and Korea. To date, it has invaded and has now established its existence in Australia, New Zealand, and several of the Pacific Islands. This species of tick has recently been introduced to the United States, having a confirmed sighting in November 2017 on a sheep farm in New Jersey and since establishing populations in 18 states along the east coast and Appalachia. Based on the existing locations of H. longicornis in its native regions, as well as in the United …

Potential Regulation Of Breast Cancer Invasion By Thymidine Kinase 1, Eliza E. Bitter, Rachel M. Morris, Toni O. Mortimer, Kai Barlow, Abigail Schekall, Michelle H. Townsend, Jonathan Skidmore, Brett E. Pickett, Kim L. O'Neill

Library/Life Sciences Undergraduate Poster Competition 2022

Breast cancer is the most common cancer in women and is largely treatable within the early stages of the disease. However, patient mortality drastically declines as the tumor begins to invade other tissues and metastasize, making aggressive phenotypes especially problematic to treat. Such treatment typically requires an aggressive and decisive multidisciplinary approach. The recent expansion of immunotherapy as a viable treatment option has greatly improved treatment outcomes, especially with aggressive breast cancer phenotypes. Thymidine kinase 1 (TK1) is a DNA salvage pathway enzyme that is highly expressed during S phase and involved in cell cycle repair. Past studies indicated that …

The Role Of Cd5 In Cd4+ T Cell Metabolism, Joshua Bennett, Kiara Whitley, Claudia Freitas Phd, Christopher Haynie, Carlos Moreno, Scott Weber

Library/Life Sciences Undergraduate Poster Competition 2022

T cells serve a key role in the immunological response in the adaptive system. Different receptors present on the T cell have certain roles and are able to either inhibit or stimulate signaling which consequently regulates the function and metabolism of the cell. CD5 is an inhibitory co receptor expressed on the surface of T cells known to regulate thymocyte selection and TCR signaling . Our goal is to better understand the effects of CD5 regulation in metabolism. Using metabolic flux assays, we found that CD5KO naïve T cells have increased glycolysis and mitochondrial respiration in comparison to wild type …

Functional Sites Within The Ihnv Nonvirion Protein That Regulate Host Cellular Responses, Jeff Ringiesn, Bartolomeo Gorgoglione, Douglas W. Leaman

Symposium of Student Research, Scholarship, and Creative Activities Materials

Fish Rhabdoviruses are responsible for causing fatal epizootics within commercial and wild populations of various fish species around the world. Infectious hematopoietic necrosis virus (IHNV), also known as the Salmonid novirhabdovirus, is enzootic along the Pacific Coast of North America and is comprised of five genogroups, each of which is endemic to a specific geographical location. Once the virus enters the host through the fin epithelia, IHNV infection causes infectious hematopoietic necrosis in salmonid species. The disease is highly fatal and presents with signs such as abdominal distension, bulging of the eyes, anemia, and necrosis of vital organs such as …

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.

Characterization Of A Putative Hemolysin Expressed By Sneathia Amnii, A Preterm Birth-Associated Pathogen, Lizette Carrasco, Kimberly Jefferson

Undergraduate Research Posters

The gram-negative bacteria Sneathia amnii is a poorly-characterized commensal of the female urogenital tract frequently associated with adverse clinical outcomes such as bacterial vaginosis (BV), amnionitis, and preterm labor. To investigate its potential role in virulence, we sought to identify and characterize virulence determinants produced by S. amnii in an effort to better understand the pathogenesis of infectious preterm birth. Through sequencing of the Sn35 genome (type strain of S. amnii), we identified two genes with amino acid sequence similarity and structural similarity to the filamentous hemagglutinin (FHA) protein of Bordetella pertussis and its Type Vb transporter. Because S. amnii …

Phi X 174, David J. Hall

Infectious Pathogens

Phi X 174 database number # 1CD3. Phi X 174 is a virus that infects bacteria and was the first DNA-based genome to be sequenced in 1977. This bacteriophage has a [+] circular single-stranded DNA genome. The assembly of the capsid has been successfully done in vitro and is the focus of many studies on self-assembly, drug delivery and nanotechnology.

Human Papilloma Virus 16, David J. Hall

Infectious Pathogens

Human Papilloma virus 16, database# 1DZL Infection by most papillomaviruses is either asymptomatic or causes small benign tumors, known as papillomas or warts (e.g. human papillomavirus HPV6 or HPV11). Papillomas caused by some types, however, such as human papillomaviruses 16 and 18, carry a risk of becoming cancerous. Human papilloma virus is a non-enveloped, double stranded, circular DNA virus.

Dengue Virus, David J. Hall

Infectious Pathogens

Dengue virus, database # 1THD Dengue fever, is an infectious tropical disease caused by the dengue virus and transmitted by mosquito. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever. Dengue is a positive strand RNA virus that is part of the flavivirus family. Dengue is an enveloped virus meaning it has a nucleocapsid protecting the RNA and the nucleocapsid is surrounded by lipids (hence the name enveloped).

Hepatitis B, David J. Hall

Infectious Pathogens

Hepatitis B, database # 2g33. Hepatitis B is an infectious inflammatory illness of the liver caused by the hepatitis B virus (HBV). Hepatitis B virus (HBV) is a member of the Hepadnavirus family.The virus particle, (virion) consists of an outer lipid envelope and an icosahedral nucleocapsid core composed of protein. These virions are 42 nM in diameter. The nucleocapsid encloses the viral DNA and a DNA polymerase that has reverse transcriptase activity.
