Be Kind To Dentists, They Have Fillings Too, Ryan Gallegos
Biology Posters
The office at ABC pediatric dentistry is bright, colorful, and has a very open concept. It is a place designed for children. The first thing patients notice when they walk in are the building blocks and toys. They can also see the giant glass windows that allow them to look into the north cleaning bay. The purpose of this is to lead by example. They can see other children getting their teeth cleaned, so they feel more comfortable letting us clean their teeth. Each colored chair has a TV placed above it and the children get to choose from one …

Evaluation Of Differential Blood Stain For Detection Of Enterovirus D68, Michael Bertolio, Bart Tarbet, Chris Peterson, Brett Hurst
Biology Posters
Enterovirus D68 (EV-D68) is a small, non-enveloped RNA virus, and is suspected to be the cause of respiratory and neurological disease in young children.1 The most concerning clinical sign is an acute flaccid paralysis of the lower limbs. At the Institute for Antiviral Research, and under the direction of Dr. Bart Tarbet, we have developed an animal model for studying EV-D68 infection. With this model, we will pursue gaining a better understanding of the neuropathogenesis of EV-D68. It has been shown, in in-vitro studies, that EV-68 is able to produce infectious progeny in leukocyte cell lines.2 We will, therefore, compare …

It is well documented that females play a prominent role in the sexual selection behavior of guppies. Working within the lab in the BNR building, our experiment sought to determine whether the presence of multiple females would, as a result of being within a more competitive environment, affect the sexual selection behavior of female guppies. As we wanted our test to be within a larger environmental context, we decided to use wild type males. One tank had one male on either side with one female in the middle, while the other tank had one male on either side and 3 …

Is Beauty Only Skin Deep? Mate Selection In Guppies, Tyson Alles, Amanda Cook, Alex Kunz, Jeff Merkley
Biology Posters
Our experiment sought to understand mate preference in female guppies, Poecilia reticulata. We observed behavioral differences between wild-type males caught from a local indoor pond and vibrant pet store males, who exhibited higher stress levels, likely due in part to being shipped long distances. Observing these behavioral differences, we hypothesized that females would prefer the less stressed males regardless of color. When a female guppy was presented with both a wild type and a pet store male, we predicted that she would prefer the wild-type male on account of their lower stress.

Zika virus (ZIKV), a mosquito-borne flavivirus, is an emerging zoonotic pathogen closely related to Japanese encephalitis virus, West Nile virus, dengue virus, and yellow fever virus. Although ZIKV infection generally produces only mild symptoms in some infected individuals, it has recently been associated with a growing number of neurological diseases, including Guillain-Barré syndrome in ZIKV-infected adults and microcephaly in infants born to ZIKV-infected women. Like all flaviviruses, ZIKV has a plus-strand RNA genome encoding ten functional proteins (designated C, prM, E, NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). Of these ten, the C (capsid) protein is an essential structural …

Spider silks are an ideal material for periodontal chips/gels because they are biocompatible, biodegradable, lightweight, strong, and create no immune response. Furthermore, the various silks types and forms allow for tunable materials and properties. Spider silk materials may have an advantage over other products because of the ability to release medication more consistently over a longer period of time and be adjusted as needed. Unlike products currently on the market, our chip/gels are biocompatible, which aids in reducing the bodies immune response to periodontal treatment. The ability to incorporate multiple bioactive compounds into the spider silk materials allows them to …

Synthesizing Spider Silk Protein From E. Coli, Mitchell Richwine
Synthesizing Spider Silk Protein From E. Coli, Mitchell Richwine
Biology Posters
Spider silk is a valuable material due to its extreme strength and elasticity. However, spider silk is difficult to produce in mass quantities because of the many factors which get in the way of producing large amounts of pure protein. Harvesting the silk from spiders is not efficient. A major issue is spiders like to kill each other until they have their own web space, so storing spiders is impractical, and the silk harvested from spiders does not allow for large quantities of the pure protein. Also the protein from spiders is only useful in producing fibers. The solution to …

Understanding the mechanisms behind nitrogen loss in soil through leaching of inorganic nitrogen helps us beWer understand mechanisms for retenMon. Hypothesis: we should see different levels of soil inorganic nitrogen in various agricultural treatments, due to the effects these treatments have on soil microbial communities. Fungi use N less efficiently than bacteria. Fungal-dominated soils should have more inorganic N than bacterial-dominated soils.

Spider Silk is one of the most unique fibers produced in the natural world. Its mechanical properties are unparalleled and have the potential to revolutionize industries around the globe. However creating this silk as it exists in nature, is difficult. Due to inability to farm orb weaving spiders that produce silk, other hosts must be inserted. This is the point of emphasis at the Spider Silk Research lab at the BioInnovations Center at Utah State University. Hosts that are currently being researched are; Silkworms, E Coli, Alfalfa, and Goats. Each of these hosts is unique in its ability to produce …
Life History Differences Across A Latitudinal Gradient In Side-Blotched Lizards (Uta Stansburiana), G. D. Smith, P. A. Zani, S. S. French
Life History Differences Across A Latitudinal Gradient In Side-Blotched Lizards (Uta Stansburiana), G. D. Smith, P. A. Zani, S. S. French
Biology Posters
Latitudinal variation has long been known to affect life history. Bergmann and Allen made latitudinal “rules” for mammalian anatomy and Lack, Skutch, and Moreau described differences in life history in birds. Trade-offs occur between important life history processes, like self maintenance (immunity) and other expensive but necessary processes. It is likely that trade-offs occur mostly when resources are limited. Side-blotched lizards have a wide geographic range, and more northerly lizards have been observed to have longer lifespans than their southern conspecifics. We hypothesized that northern sideblotched lizards would invest more energy into self-maintenance compared to shorter-lived southern animals.

Rhabdophis tigrinus, the Tiger Keelback, is native to East and Southeast Asia. It preys on amphibians, including the Japanese toad, Bufo japonicus. It secretes cardiotonic steroids known as bufadienolides (BDs) from its skin. Consumption of BDs is typically fatal in other snake species, but, R. tigrinus displays resistance to these toxins. After consuming toads, R. tigrinus sequesters BDs into glands on its neck. The adrenal glands of R. tigrinus are enlarged in comparison to similar species.

Canine breeders who are breeding to improve genetics often utilize the ability to test breeding stock for deleterious alleles. A DNA sample, such as a cheek swab or blood sample, is sent to laboratory where they determine genotypes that the owner has requested to know. Once the breeder receives results, they are better able to plan crosses or decide if a dog should be castrated to avoid the inheritance of unwanted diseases. This is particularly important with purebred dogs due to the high ratio of homozygous alleles. I will be using canine DNA for the gene ABCB1 or Multidrug Resistance …

In most cases, individuals who have a higher likeability of fruits and vegetables will consume more and reap health-related benefits because of it. However, other factors influence how the body digests, absorbs, and metabolizes the beneficial nutrients found in fruits and vegetables. Biomarkers, like carotenoids are measurable indicators of some biological state or condition. They can be helpful in understanding the relationships between dietary intake of nutrients and the other factors that may influence how a nutrient is being used in the body. Other factors known to influence skin carotenoids include body composition, exposure to environmental pollutants, or illness. Carotenoids …

With a few exceptions, all plants have chloroplasts. Chloroplasts are the organelles responsible for photosynthesis in plants. Interestingly, chloroplasts have their own genome -- called a plastome -- which is separate from the nuclear genome. The genetic composition of ferns, gymnosperm, and angiosperm plastomes are remarkably similar, revealing very little change over evolutionary time. There are however a few notable exceptions to the apparent stability of the plastome. A few lineages of both angiosperm and gymnosperm show dramatically higher rates of mutation and genetic rearrangement than those of their relatives, suggesting major genome destabilization. Vittariods are a group of ferns …

Spider silk is one of the most robust and versatile fibers making it a topic of interest in the scientific community. Possessing strength and elasticity many have sought to create fibers comparable to natural spider silk. Up until recently many scientists have fallen short of creating said fibers. With the use of a technique called electrospinning, comparable spider silk fibers have been created. Electrospinning is the process of creating fibers from a polymer solution using an electrical field. This method leads to the formation of nanofibers. These Fibers can then be further modified by crosslinking, a technique traditionally used to …

Constructing and analyzing phylogenetic trees is central to biological disciplines such as evolutionary and systematic biology. Accurate phylogenetic inference improves the estimation of evolutionary relationships, rates of molecular evolution, and Operational Taxonomic Units (OTUs). Careful alignment of sequence data is critical prior to any phylogenetic reconstruction, and there are many different multiple sequence alignment programs that are currently used (reviewed in Edgar & Batzoglou 2006). However, difficulty persists when using alignments to accurately determine actual genetic divergences. A major, yet under-explored, problem is saturation: the repetition of base substitutions at a single site within a sequence. Saturation causes issues because …
