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 ... -
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 ... -
Dying light: Detecting tree mortality risk with chlorophyll fluorescence
(Oklahoma State University, 2019-04-27)Increased greenhouse emissions have altered Earth's climate, resulting in rapid climate change which has brought warm droughts-especially in semi-arid regions-leading to forest die-off and dieback. Physiological stresses ... -
Effects of paternal deprivation on nestling zebra finches (Taeniopygia guttata)
(Oklahoma State University, 2019-04-27)Early interactions between parents and offspring have been shown to influence behavior development in avian offspring, which links to their fitness as adults. In bi-parental species, previous research has looked at what ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
How can the measurement of fluorescence help with Eastern Red Cedar disaster?
(Oklahoma State University, 2019-04-27)Juniperus virginiana, more commonly known as the Eastern Red Cedar, has caused excess economic damage due to its dynamic flammability in the Great Plains. Research on the variables in which Eastern Red Cedars are flammable ... -
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 ... -
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 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. ... -
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 ... -
Cellular senescence in cultured human brainstem astrocytes: Effect of oxidative stress
(Oklahoma State University, 2019-04-27)Cardiovascular diseases are one of the leading causes of mortality in the elderly. A central role in the contraction of cardiovascular diseases by means of aging could be played by cellular senescence. Senescent cells ... -
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 ... -
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 ... -
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 ...
