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 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 ... -
Effects of light intensity on the morphology, growth rate and phenolic content of Zygnema
(Oklahoma State University, 2021-10-09)Zygnema is a freshwater alga that forms thick mats that float at the water surface. Cells located at the surface of mats are exposed to very high visible light and UVB compared to cells deep within the mats. Previous studies ... -
Effects of organoantimony compounds on fungal pathogens Cryptococcus neoformans and Candida albicans
(Oklahoma State University, 2022-04-15)Cryptococcus neoformans is an opportunistic pathogen that causes pulmonary cryptococcosis and cryptococcal meningitis in immune-compromised individuals. Candida albicans, also opportunistic, can cause pulmonary candidiasis, ... -
Effects of pair bonding and monogamy on epididymal sperm characteristics in prairie voles (Microtus ochrogaster)
(Oklahoma State University, 2022-04-19)Prairie Voles are a social, monogamous species which have gained traction in the fields of neurobiology, neuroendocrinology, and psychology as a potential model species for studying human social behavior and associated ... -
Effects of paternal deprivation on beak coloration
(Oklahoma State University, 2022-04-19)For ornamented species, beak coloration is a key factor that is considered by the female. In zebra finches (Taeniopygia guttata), females prefer males that exhibit redder beaks in comparison to those that exhibit more ... -
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 resistance training of the foot on dance-related exercise and performance
(Oklahoma State University, 2023-04-18)The injury rate in dancers is higher than their mainstream counterparts, as dancers have a 90% injury rate compared to a 20% rate observed in rugby and football athletes. Even so, preventative equipment or techniques, such ... -
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 ... -
Electrical responses of conductive nylon for application in low cost exoskeletons for stroke rehabilitation
(Oklahoma State University, 2020-10-03)Despite the rising popularity of robotic exoskeletons, high cost and bulkiness are two limitations that hinder their popularity and everyday use. Our overarching goal is to develop an electrically powered low-cost lightweight ... -
Empathy downside: The role of empathy and autism traits in happiness
(Oklahoma State University, 2023-04-18)Prior research has shown that high empathetic people may be more prone to depression than others (Yan et al., 2021). The present research investigated the relationship between empathy and happiness. We hypothesized that ... -
Enzymatic assessment of cells with distinct TP53 mutations
(Oklahoma State University, 2021-10-09)The p53 transcription factor, encoded by the human gene TP53, is the most commonly mutated gene in human cancers. Once the TP53 gene is mutated, p53 proteins not only lose their tumor suppression abilities but can also ... -

Epigenetic modulation of avian host defense peptide synthesis
(Oklahoma State University, 2020-04-24)The threat of antibiotic resistance has catalyzed the demand for novel antibiotic alternatives in veterinary and human medicine. In response, the activation of the innate immune system has become a promising alternative ... -
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 ... -
Evaluating the effect of promoter strength on the complementation of deletion mutants in Synechocystis sp. PCC 6803
(Oklahoma State University, 2019-04-26)The CO2 uptake mechanism within Cyanobacteria plays a vital role in our environment due to its photosynthetic ability to uptake CO2 and produce oxygen. Cyanobacteria possesses an inorganic carbon concentrating mechanism ... -
Evaluation of lactic acid bacteria for a direct-fed-microbial against shigatoxigenic Escherichia coli in food animals
(Oklahoma State University, 2022-04-19)Shigatoxigenic Escherichia coli (STEC) have caused numerous foodborne outbreaks and recalls, with meat products and fresh produce as implicated vehicles. Food animals, especially ruminants, are well-known reservoirs. ... -
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 ... -
Experimental wake survey of low Reynolds number wind tunnel
