Analysis of Coxiella burnetii mediated modulation of host cells during infection
Mahapatra, Saugata (2011-07)Scope and Method of Study: Scope - To determine Coxiella burnetii mediated modulation of host cell during infection. Methods for microbiological and molecular analyses include: eukaryotic and prokaryotic cell culture, ... -
Ca2+ regulated antibiotic resistance in Pseudomonas aeruginosa
Khanam, Sharmily S. (2017-07)Pseudomonas aeruginosa, an opportunistic pathogen, causes life threatening infections in cystic fibrosis (CF) patients. Due to increased abundance of Ca2+ in CF lung, P. aeruginosa is surrounded with elevated Ca2+ that ... -
Calcium signaling in Pseudomonas aeruginosa
Guragain, Manita (2015-12)P. aeruginosa is an opportunistic pathogen and a major cause of hospital acquired infections and severe chronic infections in endocarditis and cystic fibrosis (CF) patients. During such infections, it encounters elevated ... -
Determining the role of Gɑ3, Gɑ8, and PakF in Dictyostelium signaling
Kiger, Nicholas (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 ... -
Directional growth of polypyrrole and polythiophene wires
Thapa, Prem S.; Yu, Deok Jin; Wicksted, James P.; Hadwiger, Jeffrey A.; Barisci, Joseph N.; Baughman, Ray H.; Flanders, Bret N. (AIP Publishing, 2009-01-23)This work establishes an innovative electrochemical approach to the template-free growth of conducting polypyrrole and polythiophene wires along predictable interelectrode paths up to 30 um in length. These wires have ... -
Effects of inorganic carbon limitation in wild-type and carbon sink mutants of the cyanobacterium Synechocystis sp. PCC 6803
Holland, Steven Christopher (2016-05)The efficiency of photosynthetic electron transport is an important factor in the cellular metabolism of photosynthetic organisms. The high energy molecules produced in the light reactions of photosynthesis are used to ... -
Examining the role of MekA and YakA in Dictyostelium signaling
Dreadfulwater, Stormie (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 ... -
Function and specificity in signaling pathway of two map kinases ERK1 and ERK2 in Dictyostelium
Nguyen, Hoai-Nghia (2011-05)Scope and Method of Study: MAPKs are associated with several human diseases. However, studying MAPK signaling pathways in higher eukaryotes is challenging due to presence of several MAPKs. Dictyostelium, whose genome encodes ... -
Insights into mechanisms of antifungal activity by innate immune cells
Nelson, Benjamin N. (2023-05)Cryptococcus neoformans is an opportunistic fungal pathogen that causes over 180,000 annual deaths in HIV/AIDS patients. Innate phagocytes such as dendritic cells (DCs) and macrophages are the first cells to interact with ... -
Insights into the maintenance and repair of photosystem II, a dynamic membrane protein complex
Nagarajan, Aparna (2012-12)Photosystem II (PSII) is recognized as the main site for high light induced damage. One of the core subunits of PSII, D1 protein encoded by the psbA gene, is identified as a high turnover protein that undergoes degradation ... -
Methodology for the directional growth of conducting nanowires and their attachment to live cells
Thapa, Prem (2008-12)Scope and Method of Study: -
Molecular characterization of aromatic hydrocarbon degradation in extreme halophiles
Dalvi, Sonal (2014-07)Many hypersaline environments such as natural saline lakes, salt marshes, saline industrial effluents, oil fields and coastal areas are often contaminated with high levels of petroleum hydrocarbons. Since non-halophiles ... -
Regulation of a phosphodiesterase and map kinase during dictyostelium signaling and multicellular development
Kuburich, Nick (2018-07)Many eukaryotic signaling pathways use cAMP as a secondary messenger to evoke specific responses to different external stimuli. Here, localized levels of cAMP can be controlled by phosphodiesterases, which are sometimes ... -
Role of transduction and pseudolysogeny in bacteriophage-host interactions in a natural freshwater environment
Ripp, Steven A. (1996-12) -
Structure-function relationships in the photoactive yellow protein family of photoreceptors
Rathod, Rachana Ramila Suresh (2014-12)The amino acid sequence of a protein determines its three-dimensional structure, which in turn determines its functional properties. An intensively studied but still partially unresolved question is how the structure of a ... -
Study of the recombination and DNA damage repair in Zymomonas mobilis CP4 and arthrobacter isolates
El-Masri, M. Adnan (1997-12)
