Nebraska Center for Virology: Faculty Publications

Chloroviruses are unusual among viruses infecting eukaryotic organisms in that they must, like bacteriophages, penetrate a rigid cell wall to initiate infection. Chlorovirus PBCV-1 infects its host, Chlorella variabilis NC64A by specifically binding to and degrading the cell wall of the host at the point of contact by a virus-packaged enzyme(s). However, PBCV-1 does not use any of the five previously characterized virus-encoded polysaccharide degrading enzymes to digest the Chlorella host cell wall during virus entry because none of the enzymes are packaged in the virion. A search for another PBCV-1-encoded and virion-associated protein identified protein A561L. The fourth domain …

Optometric Clinical Practice

Background: Retinitis pigmentosa is a group of hereditary retinal diseases characterized by the degeneration of rod and cone photoreceptors. It commonly results in night blindness followed by tunnel vision and central vision reduction. The classic triad of clinical signs includes pigmented bone spicules, waxy disc pallor, and arterial attenuation. Unilateral retinitis pigmentosa is rare and can be supported with ancillary testing including genetic and laboratory studies to rule out differential diagnoses.

Case Report: A 68-year-old Hispanic female was referred to the low vision rehabilitation clinic due to progressive vision loss in the left eye (OS) that began 15 years ago. …

The Anti-Sigma Factor Muca Is Required For Viability In Pseudomonas Aeruginosa, Melissa C. Schofield, Daniela Q. Rodriguez, Amanda A. Kidman, Erin K. Cassin, Lia A. Michaels, Elizabeth A. Campbell, Peter A. Jorth, Boo Shan Tseng

Teaching and Learning Faculty Research

During decades-long infections in the cystic fibrosis (CF) airway, Pseudomonas aeruginosa undergoes selection. One bacterial genetic adaptation often observed in CF isolates is mucA mutations. MucA inhibits the sigma factor AlgU. Mutations in mucA lead to AlgU misregulation, resulting in a mucoid phenotype that is associated with poor CF disease outcomes. Due to its ability to be mutated, mucA is assumed to be dispensable for bacterial viability. Here we show that, paradoxically, a portion of mucA is essential in P. aeruginosa. We demonstrate that mucA is no longer required in a strain lacking algU, that mucA alleles encoding for proteins …


The Analysis Of Folate-Dependent Transcription Factor Zinc Finger Protein 410, Feifan Xu Apr 2021

The Analysis Of Folate-Dependent Transcription Factor Zinc Finger Protein 410, Feifan Xu

Senior Honors Theses

A previous study that introduced dietary folate to mice in the form of folic acid to determine if gene activity would be altered based on this biological molecule demonstrated that mice without folic acid had cognition deficits, and this phenomenon was correlated with altered gene expression in their brains. The included bioinformatic analysis revealed two main transcription factors that bind to proteins in the nucleus, and one is known as the Zinc Finger Protein 410 (Zfp410). Due to the lack of literature explaining the function of this transcription factor, this project is intended to analyze Zfp410 in detail from scratch. …

Preferred Narratives And Their Impact On Historical Memory: An Examination Through Comparison Of Twentieth Century Pandemics, Renee Semple Apr 2021

Preferred Narratives And Their Impact On Historical Memory: An Examination Through Comparison Of Twentieth Century Pandemics, Renee Semple

Honors Scholar Theses

Societal response to a crisis and the narratives that emerge from the event(s) often vary and oppose one another. A narrative can be considered a point of view or a lens that is often cultivated through experiences and carries its own tone while telling events. This thesis compares the narratives that emerged from both the 1918 and 1957 influenza pandemics. Examining the 1918 influenza pandemic reveals both a public and a private narrative, in which the public narrative is the preferred out of the two. Filled with optimism, the preferred public narrative focused on moving forward and furthering scientific research—a …


Increasing The Frequency Of Periodic Spatial Disturbance Decreases Surface Attachment Protein Expression In Staphylococcus Aureus, Ivana M. Barraza Apr 2021

Increasing The Frequency Of Periodic Spatial Disturbance Decreases Surface Attachment Protein Expression In Staphylococcus Aureus, Ivana M. Barraza

All HCAS Student Capstones, Theses, and Dissertations

Staphylococcus aureus is an opportunistic pathogen that can cause a variety of acute and chronic illnesses. The severity of these illnesses such as sepsis, necrotizing pneumonia, and toxic shock syndrome is measured through the virulence that S. aureus inflicts on its host. Methicillin-resistant S. aureus (MRSA) is commonly associated with secondary infections and is challenging to treat given the limited selection of antibiotics that are effective against it. Accordingly, novel approaches to reduce S. aureus pathogenicity are required. S. aureus regulates pathogenesis through a cell-to-cell communication system referred to as quorum sensing. Effective communication determines the production of two broad …

Highly Branched Polymers Based On Poly(Amino Acid)S For Biomedical Application, Marisa Thompson, Carmen Scholz Apr 2021

Highly Branched Polymers Based On Poly(Amino Acid)S For Biomedical Application, Marisa Thompson, Carmen Scholz

PRC-Affiliated Research

Polymers consisting of amino acid building blocks continue to receive consideration for biomedical applications. Since poly(amino acid)s are built from natural amino acids, the same building blocks proteins are made of, they are biocompatible, biodegradable and their degradation products are metabolizable. Some amino acids display a unique asymmetrical AB2 structure, which facilitates their ability to form branched structures. This review compares the three forms of highly branched polymeric structures: structurally highly organized dendrimers, dendrigrafts and the less organized, but readily synthesizable hyperbranched polymers. Their syntheses are reviewed and compared, methods of synthesis modulations are considered and variations on their traditional …

Use Of Probiotic In Preventing Antibiotic-Associated Diarrhea, Chanda Amatya

MSN Capstone Projects

Antibiotic-associated diarrhea (AAD) including Clostridium difficile associated diarrhea (CDAD) has been a challenging topic for the healthcare industry. AAD is caused by the disruption of normal microbial balance along with the gastrointestinal (GI) tract due to the use of an antibiotic. AAD not only increases healthcare cost burden but also increases morbidity and mortality among vulnerable populations such as the elderly. Death from CDAD for a patient over 65 years is about 90% (Mallina et al., 2018). Antibiotic use is very common among the elderly and it is the responsibility of healthcare providers to take appropriate measures in preventing complications …

When COVID-19 first reached the United States the virus impacted the various states differently. By determining the initial rate of increase of the disease for each state, the basic reproduction number, can be used to determine how contagious the disease is. The basic reproduction number, denoted as $\mathcal{R}_0$, is the average number of secondary cases produced by one infectious individual in an entirely acceptable population. Using the $\mathcal{R}_0$ value determined from data collected from the state of New York, we construct SIR/SEIR models to quantify the effects of social behavior, like social distancing and wearing masks, and the relation to …

GREAT Day Posters

The SARS-CoV-2 virus is spread by infected individuals exhaling aerosols that contain active virus cells that are inhaled by another person or land on high-contact surfaces. Once the virus is inhaled, the angiotensin-converting enzyme 2 (ACE2) protein on the lung cells functions as a receptor for the SARS-CoV-2 virus. ACE2 normally converts angiotensin II (ANG II), a protein that is harmful to the lungs, into another molecule that counteracts the effects of ACE2. When ACE2 is occupied with SARS-CoV-2, ANG II will not be converted, resulting in damage to the lungs. Distancing six feet apart has become a standard guideline …

352— Investigating The Function Of Mhc Class I In Xenopus Laevis Tadpoles, Stephanie Alvarez Merlos, Annika Mounts

GREAT Day Posters

Xenopus laevis, is an excellent model organism for transgenesis and immunological research due to their large eggs and the similarities between mammalian and amphibian immune systems. MHC Class I is found on nearly all cells and educates T cells to recognize between self and non-self which is an essential immune system function. However, tadpoles don’t have detectable MHC Class I expression while adult frogs do. Despite this tadpoles are still immunocompetent; thus the role of MHC Class I in tadpoles is unknown. To investigate MHC Class I function we inactivated the corresponding gene in Xenopus laevis using CRISPR/Cas9. The …
