Adsorption and switching of single azobenzene molecules at silver nanohemisphere facets studied by Surface-enhanced Raman Scattering
Topal, Cagri Ozge (2019-07)The promise of molecular machines to control mechanical and electronic components at atomic level has brought molecular switches to the spotlight in the last decade. Among many switching molecules, azobenzene (AB) is one ... -
Biophysical effects of matrices on cellular colonization
Iyer, Pooja (Oklahoma State University, 2009-07-01)Chitosan-gelatin 3D matrices exhibit better cell viability, and significantly better functionality than the other structures which included tissue culture plastic, 2D structures, hydrogel structures and chitosan 3D structures. ... -
Concept of Viscous Heating to Reinvent the Toilet
Islam, MD. Waliul (Oklahoma State University, 2013-12-01)Highly viscous substances, such as feces, produce significant heat when layer deformation occurs. We describe the use of viscous heating to destroy disease-causing microorganisms and whipworms in feces using a small amount ... -
Design of an Axial Flow Bioreactor for Tissue Regeneration
Raja Bhaskar, Prasana (Oklahoma State University, 2012-05-01)Modeling of bioreactors using Computational Fluid Dynamics (CFD) tools have been adapted for several bioreactor configurations such as flow-through, parallel-flow, and rotary. In this study, modeling was mainly performed ... -
Designing a Bioreactor for Regenerating High Aspect Ratio Tissues
Devarapalli, Mamatha (Oklahoma State University, 2008-12-01)Many tissues have a high aspect ratio (large surface area relative to the thickness of the matrix) and contain multiple cell types. Effect of flow-through configuration within these systems has not been studied. In these ... -
Development and characterization of a novel three-dimensional human tissue-engineered lung model to study immune response to respiratory syncytial virus in vulnerable populations
Do, Taylor (2023-05)Lower respiratory illnesses are one of the leading causes of mortality in the United States. Viral lung infections, such as respiratory syncytial virus (RSV), often lead to chronic complications in immunocompromised ... -
Development of a feeding strategy for a fed-batch culture of a monoclonal antibody-producing Agarabi CHO cell line
Hanna, Abanoub (2021-07)Animal cell culture is the most extensively used platform for producing novel, recombinant DNA-based therapeutics as these cells have the required machinery to make human-like post-translational modifications. In 2017, ... -
Development of a tissue-engineered eye model to test drug delivery systems
Oswalt, Katie (2021-12)One of the leading causes of blindness is diabetic retinopathy, a disease that affects the posterior segment of the eye. Injections are commonly used to treat diabetic retinopathy, but they can lead to discomfort and low ... -
Development of tools to accelerate and advance modeling disease progression
Ruggiero, Steven MacRae (2020-12)Disease pathology emerges from complex interactions at multiple scales including the cellular level, tissue level, and organ level. Multiscale modeling seeks to capture emergent phenomena by coupling models of differing ... -
Effect of Glycated Albumin and Shear Stress on Endothelial Cell Functions
Maria, Zahra (Oklahoma State University, 2011-07-01)Our goal was to evaluate the combined effect of albumin glycation extent and physiological shear loading on endothelial cell (EC) functions. Cultured ECs were incubated with glycated or non-glycated albumin (2, 6 or 8 weeks ... -
Effects of Physiological Variables on Growth of Organohalide Respirers
Boothe, Melissa Anne (2015/12/1)There is a group of bacteria that is capable of the reductive dechlorination of chlorinated compounds, such as PCEs, by energetically using the chlorines in the compounds as terminal electron acceptors when oxygen is not ... -
Electrosprayed fiber with controllable pore size for tissue regeneration
Hong, Jong Kyu (2010-12)Scope and Method of Study: Architecture of 3D scaffold is closely related to cell behaviors such as cell infiltration, cell attachment, cell growing and cell colonization in 3D scaffold. The influence of 3D scaffold on the ... -
Evaluation of Cell Penetrating Peptide/Adenovirus Particles for Transduction of Car-negative Cells
Nigatu, Adane Sebsibe (Oklahoma State University, 2012-12-01)Adenovirus (Ad) is a promising gene therapy vector and is used currently in more than 23% of clinical gene therapy trials. The viral vector, however, has drawbacks such as immunogenicity, promiscuous tropism, and the ... -
Evaluation of Chemical Processes for Sustainable Optimization
Samli, Afshan Ibrahim (Oklahoma State University, 2011-05-01)Increasing concerns over global climate change due to greater amounts of greenhouse gases in the atmosphere or ozone depletion etc. are leading engineers to address `environmental' impacts of industrial processes. Additionally, ... -
