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 ...
Identifying and understanding multidrug resistant pathogens isolated from Cystic Fibrosis patients
(Oklahoma State University, 2019-04-26)
Cystic Fibrosis (CF) is an autosomal recessive disease caused by a mutated Cystic Fibrosis Transmembrane Conductance Regulator (CFTR), which is a chloride ion channel. When the CFTR gene is mutated, it causes the protein ...
Role of mycorrhizae in milkweeds: Implications for monarch conservation
(Oklahoma State University, 2019-04-26)
As little as 1% of the original expanse of North America's tallgrass prairie remains, and the survival of almost all grassland plants depends on the symbiotic partnership with arbuscular mycorrhizal (AM) fungi. These ...
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 ...
Quantifying the shifted baseline in breeding bird communities for Native American tribes relocated to Oklahoma
(Oklahoma State University, 2019-07-25)
Ecosystem services are often recognized for their importance in productivity (e.g., Nitrogen fixation) or biosphere support (Oxygen production from photosynthesis). Cultural ecosystem services (e.g., biodiversity appreciation) ...
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. ...
Stress response of RsbR protein paralogs in Bacillus subtilis under 1M sodium stress
(Oklahoma State University, 2019-04-26)
Stress is a universal phenomenon, and all organisms need a way to cope with it. The Model bacterium Bacillus subtilis has a complex of proteins known as a stressosome that is responsible for sensing stressors in the ...
Growth inhibition of UV filters on the freshwater microalga Scenedesmus acutus
(Oklahoma State University, 2019-04-26)
As the use of personal care products with organic ultraviolet (UV) filters are increasing, so is the exposure risk of these compounds to aquatic ecosystems. This study focuses on the inhibition growth effect of four common ...
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 ...
