Mechanism Of Interaction Of Peptide Modified Nanoparticles With Porphyromonas Gingivalis., Ankita Jain
Mechanism Of Interaction Of Peptide Modified Nanoparticles With Porphyromonas Gingivalis., Ankita Jain
Electronic Theses and Dissertations
Studies suggest that P. gingivalis functions as a keystone pathogen and interacts with primary colonizers in the supragingival biofilm such as S. gordonii. This interaction contributes to the initial colonization of the oral cavity by P. gingivalis and thus represents a potential target for therapeutic intervention. We have identified a peptide (BAR) derived from the streptococcal SspB protein that functions to inhibit P. gingivalis adherence to S. gordonii. In addition, we showed that nanoparticles (NPs) functionalized with BAR inhibit this interaction more potently than free soluble peptide, possibly by promoting interaction with P. gingivalis at higher valency than …
Modeling Picking On Pharmaceutical Tablets, Shrikant Swaminathan
Modeling Picking On Pharmaceutical Tablets, Shrikant Swaminathan
Open Access Dissertations
Tablets are the most popular solid dosage form in the pharmaceutical industry because they are cheap to manufacture, chemically and mechanically stable and easy to transport and fairly easy to control dosage. Pharmaceutical tableting operations have been around for decades however the process is still not well understood. One of the common problems faced during the production of pharmaceutical tablets by powder compaction is sticking of powder to the punch face, This is known as 'sticking'. A more specialized case of sticking is picking when the powder is pulled away form the compact in the vicinity of debossed features. In …
Crizotinib And Ceritinib Induce Apoptosis And Necrosis In Primary Rat Hepatocytes With Distinct Capacity, Alec T. Salminen
Crizotinib And Ceritinib Induce Apoptosis And Necrosis In Primary Rat Hepatocytes With Distinct Capacity, Alec T. Salminen
Biomedical Engineering Undergraduate Honors Theses
Drug development makes up a major portion of biomedical engineering research interests. The FDA oversees the introduction, experimentation, and implementation of all drugs before market approval is granted. Even after market approval is granted, the FDA continues to monitor the safety of all drugs. Crizotinib and ceritinib are two anaplastic lymphoma kinase (ALK) inhibitors recently approved by the FDA. Both drugs are indicated for treatment of non-small cell lung cancers (NSCLC) with abnormal ALK gene, and they are approved with a companion diagnostic test that determines ALK abnormality. Clinical trial data suggest that crizotinib and ceritinib can cause liver injury, …
Computational And Experimental Determination Of The Hydrodynamics In A Stirred Unbaffled Vessel Provided With Angle-Mounted Axial Impellers, Ji Ma
Theses
In most industrial applications, stirred tanks and reactors are typically provided with baffles to improve their mixing characteristics. However, in a number of pharmaceutical production facilities unbaffled vessels are commonly used. The absence of baffles is preferred in such cases because it reduces the potential for contamination and makes cleaning the vessel between batches easier. However, the lack of baffles also has a negative impact on the system’s hydrodynamics since it often results in poor mixing of the batch, especially if the impeller is centrally placed, since the liquid in such a system is subject to a strong tangential flow, …
Investigation Of Enzymatically Synthesized Glycogen As A Novel Nanodendrimer For Therapeutic Delivery, Sarah Ann Engelberth
Investigation Of Enzymatically Synthesized Glycogen As A Novel Nanodendrimer For Therapeutic Delivery, Sarah Ann Engelberth
Legacy Theses & Dissertations (2009 - 2024)
The field of medicinal chemistry is ever expanding, designing and discovering new therapeutic strategies. Oftentimes, it is challenging for these therapeutics to undergo clinical translation due to ineffective administration or unwanted toxicity in vivo. As such, drug delivery vehicles are designed to overcome these hurdles, allowing for delivery to the site of action by improving biodistribution, protecting therapeutic cargo, and decreasing toxicity. The work presented here aims to investigate a naturally-derived carbohydrate nanodendrimer, enzymatically synthesized glycogen (ESG) for drug delivery. This nontoxic, highly-branched, glucose-based structure has interior void volumes to allow for cargo encapsulation as well as a large density …
