Arenavirus Glycoprotein-Host Cell Receptor Interactions, Brayden L. Stembridge, Jonna B. Westover, Brady T. Hickerson, Brian B. Gowen

Biology Posters

Pichinde virus (PICV) is an enveloped single-stranded RNA New World arenavirus. The new world arenaviruses are divided into three separate clades designated as A, B, and C. The clade B arenaviruses are known to cause severe viral hemorrhagic fever. The clade A PICV is prevalent in the rodent population of Colombia. PICV is currently designated as a biosafety level-2 (BSL 2) pathogen due to its low pathogenicity in humans. Efforts have been made to identify the cellular receptors utilized by the virus glycoproteins to enter the host cell. Clade B arenaviruses utilize various species-specific forms of Transferrin Receptor 1 to …

Development Of Archaeal And Algalytic Bacteria Detection Systems, Andrew Walters, Anna Doloman, Charles Miller

Biology Posters

Natural gas (methane) is emerging as a viable power source for many industrial, commercial, and domestic applications. Bio-methane provides a promising replacement for mined natural gas. Methanogenic bacteria produce this bio-methane. These anaerobic bacteria pertain to the Domain Archaea, and are found in extreme environments where few other bacteria survive. They are employed by Up-Flow Anaerobic Sludge Blanket (UASB) reactors in the digestion of wastes to a marketable product (methane). The genome of methanogenic bacteria can be amplified using polymerase chain reaction (PCR), a synthetic DNA replication system. This system employs specific sequences of DNA called primers. The primers employed …

Floral Developmental Stages And Stress-Induced Reversions From Asexual To Sexual Seed Formation In Boechera (Brassiccaceae), Devin Wright

Biology Posters

In the apomictic process, plants produce a genetic copy of themselves by forming genetically-unreduced eggs (2n instead of 1n) that produce embryos parthenogenically, i.e., without fusion of egg and sperm nuclei.

• In some plants such as the Boechera species studies have shown that stressing the apomictic plants caused a reversion from apomeiosis to meiosis1.

• The object of my study is to more fully understand the stage of floral development at which an apomictic plant must be exposed to a stress signal in order to revert from apomictic to sexual reproduction or vice versa.

• Apomixis could be used …

Resistive Behaviors Of Spider Silk Nanofibers In Humidity Controlled Environments, Jesse Steadman, Nader Shehata, Ishac Kandas, Ibrahim Hassounah, Randolph V. Lewis

Biology Posters

Spider silk is becoming more useful for its desired properties as more information about the nanostructure is discovered. Due to the fact that this protein is nearly impossible to mass produce directly from the spider, the protein coding gene has been duplicated from the spider genome and inserted into the E. coli, goat, alfalfa, and silkworm genomes. This has allowed us to extract the produced protein from the transgenic hosts at a larger scale than the spiders offer. Spider silk is one of the strongest and most elastic fibers found in nature and these two characteristics, along with others others, …

From Spider To Silk: Constructions Of Synthetic Genes Of The Acinoform Spider Silk Protein (Acsp1), P. Tate Weller, Samuel T. Briggs, Paula F. Oliveira, Fernando A. Agarraberes, Randy V. Lewis

Biology Posters

Spider silks have remarkable physical properties due to a combination of strength and elasticity. In addition, spider silks are biocompatible and biodegradable. Our laboratory has shown that the strength products, such as fibers, produced with other silk proteins correlates with the size of the silk protein. The aciniform silk (AcSp1), has been shown to produce the thinnest and strongest fibers of all the natural spider silks. Aciniform silk is composed of a nonrepetitive amino-terminal region, 14 repeats of approximately 200 amino acids each, and a nonrepetitive carboxy-terminal region. We have been able to produce different versions of these genes encoding …

Optimal Fish Feed Quantity For Leatherside Chub Fry, Tyrel Hanson, Eric Wagner

Biology Posters

Leatherside chub are a threatened species and little has been studied concerning how to optimally raise them in a controlled environment. Leatherside’s are susceptible to fungal growth. This makes it difficult to balance how much feed to give the fry for their optimal development. Giving them an excess of feed can cause fungal blooms, which can kill the fry. Our goal was to better understand how much feed fry will eat at different stages of development without creating an excess of feed leading to fungal growth.

Antiviral Drug Sensitivity Of Influenza Virus Isolates Collected From Migratory Birds, Justin D. Moscon, Bart Tarbet

Biology Posters

Aquatic birds are the natural reservoirs of a wide variety of influenza A viruses. Novel influenza strains occasionally emerge from wild bird populations and spread to other species. Historically, pandemic influenza strains crossing over to humans have led to serious outbreaks. The rapid evolution of influenza strains in birds presents a major public health concern. Globalization and intensified agriculture have increased human contact with avian influenzas in the past century. Antiviral drugs effective against influenza are an important part of preparing for outbreaks, as well as common seasonal flu’s. Two major classes of antiviral drugs widely used against influenza are …

Biology Posters

Bordetella avium has been isolated from turkeys showing clinical signs of respiratory disease and increased mortality in Sanpete County Utah, despite receiving the B. avium vaccine. To determine if recent B. avium isolates are related, or unrelated to the vaccine strain, twenty-five isolates from different time periods and different locations in the U.S. were collected for comparison by MALDI-TOF mass spectroscopy. Spectra were evaluated by MALDI Biotyper software (Bruker Co.) to determine relationships among the clinical isolates. Cluster analysis of the spectra showed four major clusters using the principle component scores for the three spectral peaks in highest abundance. These …

Most Efficient Methods To Treat Breast Cancer, Esther Ehrman

The Science Journal of the Lander College of Arts and Sciences

Breast cancer is rampant in today’s world. Because there are many different cases and so many different ways to classify breast cancer, a multidisciplinary approach must be taken. Many patients undergo breast conserving surgery which creates a need for the eradication of any remaining tumor residue through radiation. Fifty Gy of radiation should be applied to the breast with an additional 16 Gy as a boost. If a mastectomy is performed to remove a large tumor and 4 or more positive lymph nodes were present, radiation should be applied as well. If the tumor expresses HER2 protein, Trastuzumab should be …

Breaking Down Barriers: The Intersection Of Medicine And Faith, Kaitlyn Lindgren, Ashley Kethcart

Fully Automated Morphological Analysis Of Patients With Obstructive Sleep Apnea, Oktay Alğin, Burak Akin, Gökhan Ocakoğlu, Evri̇m Özmen

Turkish Journal of Medical Sciences

Background/aim: Obstructive sleep apnea syndrome (OSAS) is a disease characterized by episodic hypoxia. We aimed to use the Freesurfer program for global evaluation of morphological changes in OSAS patients. Materials and methods: Three-dimensional T1-weighted images were obtained, and intracranial morphology was assessed in 18 patients with OSAS and 20 controls. Results of the volume and the cortical thickness analyses of both groups were compared statistically. Results: The total cortical, left-right hemispheres gray matter (GM), corpus callosum, and total GM volumes were lower in OSAS patients when compared with the control group (P < 0.001). The average cortical thickness was lower in OSAS patients bilaterally in pars orbitalis, paracentral, rostral middle frontal, middle frontal, orbital, and superior frontal gyri when compared with the control group (P < 0.05). Furthermore, the volume and average cortical thickness of multiple anatomic regions, apart from the brain parts mentioned above, were decreased unilaterally (e.g., hippocampus, cingulum, putamen, thalamus) in OSAS patients (P < 0.05). Conclusion: Multiple morphologic changes occur in the cerebral structures of OSAS patients due to intermittent ischemia episodes. Detection of those areas with Freesurfer is easier. New studies with large series would be needed for these subjects.
