Electromechanical Effects On Micro And Nano Particles Generated From Drug Delivery Devices And Their Implications In Flow And Deposition Efficiency, Mohammed Ali, Mark Miller
Electromechanical Effects On Micro And Nano Particles Generated From Drug Delivery Devices And Their Implications In Flow And Deposition Efficiency, Mohammed Ali, Mark Miller
Technology Faculty Publications and Presentations
This experimental investigation was undertaken to quantify the electrostatic charge and aerodynamic size distribution of the medicinal drug particles inhaled through an in-vitro mouth-throat (MT) in order to compare the amount of drugs can be delivered to the human lung while mimicking a patient is either sitting or lying. The MT model is a cadaver-based replica cast of human oral-pharyngeal-laryngeal region. Tested drug aerosols were generated by a commercially available metered dose inhaler (MDI). The MT model was placed inside a humidity (95%) and temperature (37oC) controlled chamber. Its mouth-inlet was positioned horizontally and vertically to simulate sitting …

Theses & Dissertations
Cancer is the leading cause of death in the United States and its high mortality rate can be attributed towards poor diagnosis methods and less effective therapeutic treatments. Many nanotechnology-based diagnostics and therapeutics are being developed to improve cancer patient outcomes. In this work, we have studied nanoparticles for diagnostic and therapeutic applications in cancer treatment.
In the first work, novel fluorescent NPs loaded with indocyanine green (ICG) were developed for bioimaging applications of pancreatic cancer. Targeted fluorescent nanoparticles (NPs) are being developed to image a range of cancer types with the goal to improve patient outcomes by utilizing in …
Delivery Of Sirna With Drugs Targeting Polyamine Metabolism As Combinational Cancer Treatment, Ao Yu
Delivery Of Sirna With Drugs Targeting Polyamine Metabolism As Combinational Cancer Treatment, Ao Yu
Theses & Dissertations
Cancer has been a major public health issue worldwide for years and is the second leading cause of death in the United States. Important barrier must be broken to extend the life expectancy in every country. The standard care for cancer causes severe side effects which affects patients’ physical health and quality of life. Polyamines are highly related with the cell proliferation and apoptosis. Dysregulated polyamine metabolism in cancer leads to increased polyamine concentration in neoplastic cells. Thus, polyamine metabolism for cancer therapy can be an intriguing target. However, the heterogeneity affecting key cancer pathways poses significant challenges for effective …
An Investigation Into Formulation And Therapeutic Effectiveness Of Nanoparticle Drug Delivery For Select Pharmaceutical Agents, Dustin Cooper
An Investigation Into Formulation And Therapeutic Effectiveness Of Nanoparticle Drug Delivery For Select Pharmaceutical Agents, Dustin Cooper
Electronic Theses and Dissertations
Drug based nanoparticle (NP) formulations have gained considerable attention over the past decade for their use in various drug delivery systems. NPs have been shown to increase bioavailability, decrease side effects of highly toxic drugs, and prolong drug release. Furthermore, polymer based, biodegradable nanodelivery has become increasing popular in the field of NP formulation because of their high degree of compatibility and low rate of toxicity. Due to their popularity, commercially available polymers such as poly lactic acid (PLA), poly glycolic acid (PGA) and polylactic-co-glycolic acid (PLGA) are commonly used in the development and design of new nano based delivery …

Recombinant subunit vaccines are an efficient strategy to meet the demands of a possible influenza pandemic, because of rapid and scalable production. However, vaccines made from recombinant Hemagglutinin (HA) subunit protein are often of low potency, requiring repeated boosting to generate a sustained immune response. Previously, we demonstrated improved immunogenicity of a plant-made H1 Hemagglutinin (HA) vaccine by chemical conjugation to the surface of the Tobacco Mosaic Virus (TMV) which is non infectious in mammals. Antigen coated TMV is taken up by mammalian dendritic cells and is a highly effective antigen carrier for subunit protein vaccines. In this work, we …

We have developed a transencapsidated vaccine delivery system based on the insect virus, Flock House virus (FHV). FHV is attractive due to its small genome size, simple organization, and non-pathogenic characteristics. With the insertion of a Tobacco mosaic virus (TMV) origin of assembly (Oa), the independently replicating FHV RNA1 can be transencapsidated by TMV coat protein. In this study we demonstrated that the Oa adapted FHV RNA1 transencapsidation process can take place in planta, by using a bipartite plant expression vector system, where TMV coat protein is expressed by another plant virus vector, Foxtail mosaic virus (FoMV). Dual infection in …
Nanoparticulate Drug Delivery Platforms For Advancing Bone Infection Therapies, Vuk Uskoković, Tejal A. Dasai
Nanoparticulate Drug Delivery Platforms For Advancing Bone Infection Therapies, Vuk Uskoković, Tejal A. Dasai
Pharmacy Faculty Articles and Research
Introduction—The ongoing surge of resistance of bacterial pathogens to antibiotic therapies and the consistently aging median member of the human race signal an impending increase in the incidence of chronic bone infection. Nanotechnological platforms for local and sustained delivery of therapeutics hold the greatest potential for providing minimally invasive and maximally regenerative therapies for this rare but persistent condition.
Areas covered—Shortcomings of the clinically available treatment options, including poly(methyl methacrylate) beads and calcium sulfate cements, are discussed and their transcending using calcium-phosphate/polymeric nanoparticulate composites is foreseen. Bone is a composite wherein the weakness of each component alone is …

Tobacco Mosaic virus (TMV) coat protein is well known for its ability to self-assemble into supramolecular nanoparticles, either as protein discs or as rods originating from the ~300 bp genomic RNA origin-of-assembly (OA). We have utilized TMV self-assembly characteristics to create a novel Flock House virus (FHV) RNA nanoparticle. FHV encodes a viral polymerase supporting autonomous replication of the FHV genome, which makes it an attractive candidate for viral transgene expression studies and targeted RNA delivery into host cells. However, FHV viral genome size is strictly limited by native FHV capsid. To determine if this packaging restriction could be eliminated, …

Development Of Cytarabine Prodrugs And Delivery Systems For Leukemia Treatment, Bhupender S. Chhikara, Keykavous Parang
Pharmacy Faculty Articles and Research
Importance of the field: Cytarabine is a polar nucleoside drug used for the treatment of myeloid leukemia and non-Hodgkin’s lymphoma. The drug has a short plasma half-life, low stability, and limited bioavailability. Overdosing of patients with continuous infusions may lead to side effects. Thus, various prodrug strategies and delivery systems have been extensively explored to enhance the half-life, stability, and delivery of cytarabine. Among the recent cytarabine prodrugs, amino acid conjugate ValCytarabine and fatty acid derivative CP-4055 (in phase 3 trials) have been investigated for the treatment of leukemia and solid tumors, respectively. Alternatively, delivery systems of cytarabine have …
