Effects of L protein on MreB and cell lysis
(Oklahoma State University, 2018-04-19)The MS2 bacteriophage is a single-stranded, positive-strand RNA virus that contains four genes: mat, coat, rep, and L. The L protein is responsible for cell lysis, although relatively little is known about its mode of ... -
How temperature may affect horses: Using ethograms to examine horse behavior based on variations in weather
(Oklahoma State University, 2019-04-27)This study is to serve as a baseline for future research regarding horses. The study was conducted by observing the horse's behavior and characteristics in various weather conditions from a proximal distance of 75 ft (25 ... -
DNA barcoding for identifying zooplankton
(Oklahoma State University, 2019-04-27)DNA barcoding is still a relatively new field of study that is gaining popularity as it becomes more available. But there is no single protocol that works consistently and efficiently. While there are protocols that have ... -
Client depletion assay comparison of paclitaxel to Hsp90 inhibitors
(Oklahoma State University, 2019-04-27)Many researchers have claimed they have found a successful inhibitor of Hsp90; however, we suspect they are only successful when the inhibitor is used in large quantities. On top of being one of the easiest ways to show ... -
Beta-lactamases in the multidrug resistance opportunistic bacterial pathogen Elizabethkingia anophelis
(Oklahoma State University, 2019-04-27)Beta-lactamases are bacterial enzymes that pose a serious threat within the healthcare field due to their antibiotic resistance towards commonly prescribed antibiotics, including penicillins, cephalosporins, and cephamycins. ... -
Effect of idiographic worry on emotional processing
(Oklahoma State University, 2019-04-27)Emotional processing to internal threat is increasingly being studied as a way to evaluate the effect of worry on attention. The current study seeks to use event related potentials (ERPs), specifically the Late-Positive ... -
Effects of 17β-estradiol on gonadal morphology in Acris blanchardi
(Oklahoma State University, 2019-04-27)Endocrine disrupting compounds, like 17β-estradiol (E2), contaminate wildlife habitats, which leaves organisms vulnerable to compounds that have adverse effects on their gonadal development. Amphibians are the most vulnerable ... -
Effects of vancomycin and ceftazidime on biofilm formation in Elizabethkingia
(Oklahoma State University, 2019-04-27)Elizabethkingia infections are associated with high mortality rates which is due in part to the antibiotic resistance expressed by all Gram-negative Elizabethkingia species. Biofilm formation by Elizabethkingia provides ... -
Treatment of Wilson's disease with alpha lipoic acid
(Oklahoma State University, 2019-04-27)Wilson's disease is the malfunction of the copper removing protein ATP7B. This rare, genetic disease affects the body by accumulating copper in vital organs such as the liver, brain, and eyes. There are currently two drugs ... -
Effect of microhabitat and body size on toe pad size in arboreal, semi-arboreal, and torrential frogs
(Oklahoma State University, 2019-04-27)Frogs can be classified into specialized microhabitats, and for our study, we chose to focus on arboreal (tree dwelling), semi-arboreal (tree and terrestrial dwelling), and torrential (freshwater stream dwelling) species. ... -
Phylogeny of Sonoran Desert milkweeds resolved with plastid genome sequences
(Oklahoma State University, 2019-04-27)The Sonoran Desert Clade milkweeds have very unusual traits, including species that are nearly leafless and shrubby. This clade includes 9 species for which we estimate a phylogenetic tree and use this information to better ... -
Distribution of Daphnia resting eggs: Invasive vs native and their effects
(Oklahoma State University, 2019-04-27)Daphnia lumholtzi is an example of a successful aquatic invasive species. When conditions are less favorable, D. lumholtzi switch from producing female eggs to the production of diapausing eggs (called ephippia) that are ... -
Determining the role of Gɑ3, Gɑ8, and PakF in Dictyostelium signaling
(Oklahoma State University, 2019-04-27)Dictyostelium discoideum is a free-living amoeba found in the soil. Dictyostelium (commonly referred to as "slime mold") exists as a unicellular amoeba in optimal environmental conditions. In suboptimal conditions (specifically ... -
Evaluating the core microbiome of Manduca sexta
(Oklahoma State University, 2019-04-27)Microbiomes are complex communities of microorganisms that colonize many surfaces of an animal's body, especially those niches lined with carbohydrate-rich mucosal layers such as the eyes, male and female reproductive ... -
Feeding behavior of Acheta domesticus infected with Paragordius varius
(Oklahoma State University, 2019-04-27)There has not been a lot of research on the phylum nematomorpha, hairworms. There is a large gap in the knowledge of hairworms in their host-parasite relationship, especially on their dietary habits. Our study observed the ... -
Single step polyfluoroarylation of amides
(Oklahoma State University, 2019-04-27)Per- and polyfluoroarenes are important synthetic chemistry targets because they are active components in many pharmaceuticals, agrichemicals, and industrial manufacturing products. Many of the current methods of synthesizing ... -
Examining the role of MekA and YakA in Dictyostelium signaling
(Oklahoma State University, 2019-04-27)A series of trials were conducted to determine how each protein or kinase plays a role in the signaling of a cell. Among the factors tested were response time, extent of response, and the response under varying stimuli ... -
Predator-prey interactions with Physa acuta
(Oklahoma State University, 2019-04-27)Freshwater communities can be complex with the predatory strategies that take place within them. Gastropods are an example of a typical prey that is found within these freshwater communities. Their predators give off a ... -
Interacting effects of soil microbes and spiders on plant growth
(Oklahoma State University, 2019-04-27)Biotic factors contribute greatly to the success of nutrient cycling, this is done by recycling and translocating nutrients microbe. Research has shown that high densities of predators affect the amount of nutrients deposited ... -
