Role Of Fyn And Lyn In Igg-Mediate Immune Responses, Yves Falanga
Role Of Fyn And Lyn In Igg-Mediate Immune Responses, Yves Falanga
Theses and Dissertations
Anaphylaxis is a rapid, life-threatening hypersensitivity reaction. Until recently, it was mainly attributed to histamine released by mast cells activated by allergen crosslinking (XL) of FcεRI-bound allergen-specific IgE. However, recent reports established that anaphylaxis could also be triggered by basophil, macrophage and neutrophil secretion of platelet activating factor subsequent to FcγR stimulation by IgG/Ag complexes. I have investigated the contribution of Fyn and Lyn tyrosine kinases to FcγRIIb and FcγRIII signaling in the context of IgG-mediated passive systemic anaphylaxis (PSA). I found that mast cell IgG XL induced Fyn, Lyn, Akt, Erk, p38 and JNK phosphorylation. Additionally, IgG XL of …

Behavioral Phenotyping Of The Discriminative Stimulus Properties Of The Atypical Antipsychotic Drug Clozapine In 129s2/Hsv Mice, Kevin Webster
Theses and Dissertations
The 129S2 inbred mouse strain is often used as a background strain in the production of genetically altered mice (i.e. knockout and transgenic mice). It is important to establish the behavioral phenotype of wild-type mice before making comparisons to genetically altered mice. Also, those comparisons can assist in the evaluation and interpretation of the in vivo effects of drugs. The drug discrimination assay measures the subjective effects of drugs and provides a measure of underlying neuropharmacological mechanisms responsible for the discriminative stimulus properties of drugs. The present study established the atypical antipsychotic drug clozapine as a discriminative stimulus in male …

An Agent Based Model Of Tumor Growth And Response To Radiotherapy, Nicole O'Neil
An Agent Based Model Of Tumor Growth And Response To Radiotherapy, Nicole O'Neil
Theses and Dissertations
An agent based model was developed to examine the growth of a tumor in a healthy cell population. Response to radiation and impact of mutation and bystander effects were studied. In the growth model, the cancer cells proliferated outward becoming invasive. The mass of cancer cells developed a necrotic core. Various treatment protocols of radiation were compared. Timing of treatments was critical to the success of therapy. The event of mutation was rare. When mutation occurred, either unsuccessful treatment or re-growth could result. Multiple rounds of radiation potentially led to increased mutation. Low levels of the bystander effect had little …
The Effects Of Aspirin And Cyclosporine On Canine Platelet Function And Cyclooxygenase Expression, John Metcalfe Thomason
The Effects Of Aspirin And Cyclosporine On Canine Platelet Function And Cyclooxygenase Expression, John Metcalfe Thomason
Theses and Dissertations
Immune-mediated hemolytic anemia (IMHA) is one of the most common causes of anemia in dogs. Despite aggressive therapy, there is a 50% mortality rate in IMHA patients, and the most common cause of death is thromboembolic disease, particularly pulmonary thromboembolism. With the high thromboembolism rate in dogs with IMHA, anti-platelet therapy with aspirin can be a life-saving preventative therapy. Along with anti-platelet therapy, immunosuppressive therapy is needed to decrease erythrocyte destruction. Cyclosporine has become a popular medication for immunosuppression in IMHA patients. Unfortunately, recent human reports have suggested that cyclosporine could activate platelets and contribute to a hypercoagulable state. With …

Gonnorrhea is an infectious sexually transmitted disease (STD) caused by the bacterium Neisseria gonorrhoeae that commonly reproduces in the reproductive tract.The Centers of Disease Control and Prevention (CDC) estimate that more than 700,000 individuals in the U.S. contract new gonorrheal infections per year. During recent years, there has been a progressive global increase of drug-resistant strains of gonorrhea. Therefore, there exists the necessity for health organizations to encourage the monitoring, research and development of innovative treatment regimens. We have developed multiple mathematical models to explore the gonorrheal disease state. The first objective of model formulation was to fit the model …
Expression Of Foreign Genes In The Pseudomonas Bacteriophage Pf3, Krystin Weathers
Expression Of Foreign Genes In The Pseudomonas Bacteriophage Pf3, Krystin Weathers
Theses and Dissertations
Filamentous bacteriophages were engineered to express foreign genes with the ultimate purpose of displaying transmission control anti-malarial peptides as in phage display. It was hypothesized that expression of foreign genes would be possible using the phage’s promoters. This hypothesis was tested by assuming that promoters for the phage major coat protein (MCP) gene would also promote the expression of any foreign gene inserted downstream of the MCP gene. As proof of principle, the bacteriophages Pf3, Pf1, and M13 were engineered in this way to successfully synthesize Enhanced Green Fluorescent Protein (EGFP). Type 88 phage display on the EGFP recombinant Pf3 …

Semi-Interpenetrating Nanofiber Scaffolds For Transbuccal Drug Delivery, Donald Aduba Jr.
Semi-Interpenetrating Nanofiber Scaffolds For Transbuccal Drug Delivery, Donald Aduba Jr.
Theses and Dissertations
The oral buccal mucosa is a promising absorption site for drug administration because it is permeable, highly vascularized and allows ease of administration. Although there are many platforms that have been used for drug delivery, nanofiber scaffolds as a platform for local or systemic drug delivery through the oral mucosa have not been fully explored. In this thesis, we fabricated a biocompatible electrospun gelatin nanofiber scaffold for local drug delivery at the oral mucosa. To stabilize the electrospun gelatin nanofibers and allow non-invasive incorporation of therapeutics into the scaffold, photo-reactive polyethylene-glycol (PEG)-diacrylate was employed to crosslink the scaffold to form …

Assessing The Genotoxicity Of Triclosan In Tadpoles Of The American Bullfrog, Lithobates Catesbeianus., David Emery
Theses and Dissertations
Amphibians are particularly sensitive to environmental degradation and, therefore, serve as effective environmental quality indicators. Research has suggested that amphibian declines are exacerbated by manmade environmental toxicants, especially those found in high concentrations in urban areas. The NIH has pinpointed genotoxicity as a major route of cancer causation, and has since developed stringent testing procedures for potentially hazardous chemicals. One such method, recognized for its simplicity and economy, is the micronucleus assay. A study was conducted assessing the genotoxicity of the widely used antimicrobial agent Triclosan to American Bullfrog tadpoles. Lithobates catesbeianus tadpoles were reared in glass aquaria containing ultra-high …

Characterization Of Truncated Yscf: Innate Immune And Proinflammatory Responsiveness, Melody N. Toosky
Theses and Dissertations
Yersinia pestis, the causative agent of plague, is a highly pathogenic gram negative bacterium that attenuates the host immune response by translocating effector proteins, known as Yops, directly from the bacterial cytoplasm into the eukaryotic cell cytoplasm using a Type III secretion system. The Type III secretion system uses a polymerized needle to translocate Yops into the eukaryotic cell. This self-polymerizing needle is composed of YscF. YscF has been tested as a possible vaccine alternative to other subunit vaccines. Wild type YscF has been previously shown to provide a low amount of protection against challenge with Y. pestis. The focus …

The Impact Of Conflict Type On Child And Infant Mortality Rates: Evidence From Global Data, Ubah Abdulgani Adan
Theses and Dissertations
Wars kill, destroy, cause havoc and leave lasting impacts on the societies affected. Infants and children are particularly susceptible to these shocks. This thesis looked at whether there is a differential impact across different types of war (civil and international) on child mortality rates among children in different age groups (neonatal, post neonatal, infant, ages 1-5, and under-5). An unbalanced dynamic panel dataset, from 155 countries covering a period of 30 years (1970-1999) was used in this analysis. The empirical results showed that international war contributed more to the rise of neonatal mortality than did civil war. Conversely, civil war …

Predictors Of Carbapenem Resistant Gram-Negative Bacteria In A Consortium Of Academic Medical Center Hospitals, Mera Ababneh
Theses and Dissertations
Background: Gram-negative resistance is a growing problem worldwide. It is generally believed that rates of resistant bacteria within a hospital are a function of antibiotic use, resistant organisms brought into the hospital, infection control efforts, and underlying severity of patient illness. The relative contribution of each to a particular resistance phenotype is unclear. P. aeruginosa is responsible for many hospital acquired infections and it may become resistant to carbapenems. In addition, newer threats to the future utility of the carbapenems are carbapenemase-producing K. pneumoniae Purpose: To determine if there is an association between the volume and composition of antibiotic use, …
Psychology And People Living With Hiv/Aids: A Critical Review Of The Literature, David Fischer
Psychology And People Living With Hiv/Aids: A Critical Review Of The Literature, David Fischer
Theses and Dissertations
The implications of living with Human Immunodeficiency Virus (HIV) have evolved over the last 30 years. The view of HIV infection as an imminent death sentence has largely disappeared. From a practical perspective, HIV positive status is now medically treated as a chronic illness rather than as a terminal diagnosis. In response, the focus of psychological research and therapeutic practice has evolved to reflect the changing implications of living with HIV. This study documents how psychological literature regarding people living with HIV has changed over the course of the epidemic.

Response To And Recovery From Endotracheal Suctioning In Preterm Infants Using Routine Versus Four-Handed Care, Sharon Cone
Theses and Dissertations
Neonatal Intensive Care Units have experienced profound advances in technology and treatment modalities over the last two decades. Infants born at the edge of viability are now surviving despite prolonged hospitalizations. These infants born preterm are prone to a high degree of stress from life sustaining and routine interventions. Much focus has been directed toward addressing noxious environmental factors such as noise, light, and infectious disease; however, little has been done to examine the stress experienced by the professional caregiver who work in these environments. Environmental press theory, which focuses on the interplay between human beings and their surroundings, is …
