Exogenous Surfactant As A Delivery Vehicle For Intrapulmonary Therapeutics, Brandon J. Baer
Exogenous Surfactant As A Delivery Vehicle For Intrapulmonary Therapeutics, Brandon J. Baer
Electronic Thesis and Dissertation Repository
As an organ system, the lung has unique advantages and disadvantages for direct drug delivery. Its contact with the external environment allows for the airways to be easily accessible to intrapulmonary delivery. However, its complex structure, which divides into more narrow airways with each branch, can make direct delivery to the remote alveoli challenging. The objective of this thesis was to overcome this issue by using exogenous surfactant, a lipoprotein complex used to treat neonatal respiratory distress syndrome, as a carrier for pulmonary therapeutics. It was hypothesized that therapeutics administered with a surfactant vehicle would display enhanced delivery to the …
Molecular Dynamics Simulations Of Self-Assemblies In Nature And Nanotechnology, Phu Khanh Tang
Molecular Dynamics Simulations Of Self-Assemblies In Nature And Nanotechnology, Phu Khanh Tang
Dissertations, Theses, and Capstone Projects
Nature usually divides complex systems into smaller building blocks specializing in a few tasks since one entity cannot achieve everything. Therefore, self-assembly is a robust tool exploited by Nature to build hierarchical systems that accomplish unique functions. The cell membrane distinguishes itself as an example of Nature’s self-assembly, defining and protecting the cell. By mimicking Nature’s designs using synthetically designed self-assemblies, researchers with advanced nanotechnological comprehension can manipulate these synthetic self-assemblies to improve many aspects of modern medicine and materials science. Understanding the competing underlying molecular interactions in self-assembly is always of interest to the academic scientific community and industry. …
Effect Of Carbon Monoxide Releasing Molecule 3 (Corm - 3) On Platelet Adhesion To Human Brain Microvascular Endothelial Cells, Najat S. El-Farra
Effect Of Carbon Monoxide Releasing Molecule 3 (Corm - 3) On Platelet Adhesion To Human Brain Microvascular Endothelial Cells, Najat S. El-Farra
Undergraduate Student Research Internships Conference
Sepsis is characterized by the widespread inflammation of the body. Systemic inflammation activates and recruits inflammatory cells (e.g., leukocytes) and platelets to the affected organs.
During these inflammatory conditions, human brain microvascular endothelial cells (hBMEC) and platelets both upregulate adhesive molecules rendering platelets to adhere to hBMEC.
Although carbon monoxide is thought of as a toxic molecule to many, previous work shows its anti-inflammatory properties. Evidence has shown carbon monoxide-releasing molecules (e.g., CORM-3; that release small, non-toxic amounts of CO) can combat the effects of severe inflammation in several in vivo animal model.
In this current study, we are looking …
The Effects Of Increasing Positively Charged Metal Ions Within Synovial Fluid, Kandisi Anyabwile
The Effects Of Increasing Positively Charged Metal Ions Within Synovial Fluid, Kandisi Anyabwile
Williams Honors College, Honors Research Projects
Osteoarthritis is a degenerative joint disease that affects 10% of men and 13% of women over age of 60. It is the degradation of the cartilage between two bones; obesity, age, overuse, or injury are major contributors to the development of this disease. The joint is incapsulated by the synovial sac filled with a viscous solution that aids in lubrication referred to as synovial fluid. If the synovial sac is ruptured due to injury, positive ions (K+, Na+, Ca2+, and Fe3+) may affect viscoelastic properties within the sac. The purpose of this …
Dna Damage Recognition And Uvrb Loading By Uvra Within The Nucleotide Excision Repair Pathway, Silas Hartley
Dna Damage Recognition And Uvrb Loading By Uvra Within The Nucleotide Excision Repair Pathway, Silas Hartley
Dissertations, Theses, and Capstone Projects
Maintaining the cellular genome is paramount to survival by any organism. A mutated genome can have detrimental effects on different cellular processes, especially replication and transcription. Cells maintain their genome using different deoxyribonucleic acid (DNA) repair pathways. The nucleotide excision repair (NER) pathway has a unique capability of repairing the genome from several different mutations, deletions, and adducts. In bacteria, the NER pathway accomplishes repair through four important steps: damage recognition by UvrA, damage verification by UvrB, DNA incision by UvrC, and repair synthesis using various cellular machinery.
UvrA forms a head-to-head dimer (UvrA2) with two ATPase sites …
Analysis Of Biofilm Remediation Capacity For Octenyl Succinic Anhydride (Osa), A Bioactive Food Starch Modifier Compound, Matthew R. Borglin
Analysis Of Biofilm Remediation Capacity For Octenyl Succinic Anhydride (Osa), A Bioactive Food Starch Modifier Compound, Matthew R. Borglin
Master's Theses
Matthew R. Borglin
This thesis demonstrates efficacy of Octenyl Succinic Anhydride (OSA), as a biofilm sanitizer. Biofilms allow bacteria to adhere to solid surfaces with the use of excreted polymeric compounds. For example, surfaces found in food production or processing facilities such as the interior of a raw milk holding tank, are some of the most susceptible to biofilm contamination. When present, biofilms can cause a variety of negative effects, which include; reduction of product shelf life, corrosion, and outbreaks of foodborne illnesses. The close association of biofilms with the majority of foodborne illness cases led the US Environmental Protection …
Excess No Stabilizes The Luminal Domain Of Stim2 In A Cys-Specific Manner Thereby Regulating Basal Calcium Homeostasis And Store-Operated Calcium Entry, Matthew Novello
Excess No Stabilizes The Luminal Domain Of Stim2 In A Cys-Specific Manner Thereby Regulating Basal Calcium Homeostasis And Store-Operated Calcium Entry, Matthew Novello
Electronic Thesis and Dissertation Repository
Stromal-interaction molecule 2 (STIM2) is an endoplasmic reticulum (ER) membrane-inserted Ca2+-sensing protein which, together with the plasma membrane Ca2+ channel Orai1, regulates basal Ca2+ homeostasis and store-operated Ca2+ entry (SOCE). Recent evidence suggests that S-nitrosylation, which is the covalent attachment of a nitric oxide (NO) moiety to a cysteine thiol, can attenuate the function of the paralog STIM1 protein. Compared to STIM1, STIM2 also functions as a basal Ca2+ homeostatic feedback regulator. Therefore, the objective of my study was to evaluate the susceptibility of STIM2 to S-nitrosylation and the effects that this …

Single-molecule binding assays enable the study of how molecular machines assemble and function. Current algorithms can identify and locate individual molecules, but require tedious manual validation of each spot. Moreover, no solution for high-throughput analysis of single-molecule binding data exists. Here, we describe an automated pipeline to analyze single-molecule data over a wide range of experimental conditions. In addition, our method enables state estimation on multivariate Gaussian signals. We validate our approach using simulated data, and benchmark the pipeline by measuring the binding properties of the well-studied, DNA-guided DNA endonuclease, TtAgo, an Argonaute protein from the Eubacterium Thermus thermophilus. We …
The Effect Of Hemodynamic Force On The Maturation Of Blood Vessels During Embryogenesis, Rachel Lee Padget
The Effect Of Hemodynamic Force On The Maturation Of Blood Vessels During Embryogenesis, Rachel Lee Padget
MSU Graduate Theses
Throughout embryonic development, blood vessels are derived from endothelial cells by way of vasculogenesis. During angiogenesis, vessels remodel to form a hierarchy of large-diameter arteries that branch into small-diameter capillaries. In this maturation, vessels respond to unidentified signaling events to become surrounded with an outer layer of vascular smooth muscle cells (vSMCs). This results in arteries that have a thick vSMC layer, veins that have a thin vSMC layer, and capillaries that have a very thin or absent vSMC layer. What remains to be determined is the cause of the thicker layer of vSMCs around proximal arteries. Previous studies …
