Development Of Novel Zika And Anthrax Viral Nanoparticle Vaccines, Elizabeth Henderson
Development Of Novel Zika And Anthrax Viral Nanoparticle Vaccines, Elizabeth Henderson
KGI Theses and Dissertations
Vaccines protect against numerous infectious diseases and prevent millions of deaths annually, but there are still many infectious diseases for which no licensed vaccine exists. Developing a new vaccine requires balancing safety and efficacy, and viral nanoparticle (VNP) vaccines possess both of these characteristics. The work herein demonstrates how tobacco mosaic virus (TMV) nanoparticles can serve as a platform to create candidate vaccines for Zika virus (ZIKV) and anthrax. In the first study, a ZIKV-specific epitope was genetically fused to TMV to create a safe and inexpensive vaccine that proved highly immunogenic in mice and led to the discovery of …
Identification Of Antibiotic Ge37468a From Pseudonocardia Symbionts Of Trachymyrmex Septentrionalis Ants, Krithika Rao
Identification Of Antibiotic Ge37468a From Pseudonocardia Symbionts Of Trachymyrmex Septentrionalis Ants, Krithika Rao
Scripps Senior Theses
In response to the growing rates of antibiotic resistance in human bacterial pathogens, this study explores the natural products involved in the defensive symbiosis between actinobacteria and fungus-growing ants to uncover new potential antibiotics. This study also seeks to understand the function of natural antibiotics in their ecological contexts, especially those involved in defensive symbioses. Defensive symbiosis can be a beneficial platform for discovering useful antibiotics, because antibiotics in these relationships must be able to selectively inhibit enemies without harming hosts, and are therefore likely more specific and less toxic. Pseudonocardia sp. associated with Trachymyrmex septentrionalis ants demonstrated antibiotic activity …
Detection Of Sickle Cell Disease-Associated Single Nucleotide Polymorphism Using A Graphene Field Effect Transistor, Kandace Fung
Detection Of Sickle Cell Disease-Associated Single Nucleotide Polymorphism Using A Graphene Field Effect Transistor, Kandace Fung
CMC Senior Theses
Sickle Cell Disease (SCD) is a hereditary monogenic disorder that affects millions of people worldwide and is associated with symptoms such as stroke, lethargy, chronic anemia, and increased mortality. SCD can be quickly detected and diagnosed using a simple blood test as an infant, but as of now, there is currently limited treatment to cure an individual of sickle cell disease. Recently, there have been several promising developments in CRISPR-Cas-associated gene-editing therapeutics; however, there have been limitations in gene-editing efficiency monitoring, which if improved, could be beneficial to advancing CRISPR-based therapy, especially in SCD. The CRISPR-Chip, a three-terminal graphene-based field …
Giardia Lamblia Growth In Viscoelastic Fluids, Kelly Watanabe
Giardia Lamblia Growth In Viscoelastic Fluids, Kelly Watanabe
CMC Senior Theses
Giardia lamblia is a single-celled protozoan parasite that when ingested, causes diarrheal disease and infects 33% of people in developing countries. Previous studies observe Giardia in water-like fluids, but Giardia's infectious environment consists of viscoelastic mucus in the small intestine. Therefore, Giardia was cultured in viscoelastic fluids, and its population growth was observed in vitro. To create shear-thinning viscoelastic fluids, 0.2% and 0.4% long-chain polyacrylamide (LCPAM) was added to cell culture media. Giardia was cultured in control media, 0.2% LCPAM, and 0.4% LCPAM, and population growth was quantitatively determined over time. Increasing LCPAM concentration resulted in a solution with …
The Role Of Serum Histones In Canine Heat Stroke, Jenna Acutt
The Role Of Serum Histones In Canine Heat Stroke, Jenna Acutt
Scripps Senior Theses
Rising temperatures all over the world has correlated with more frequent heat stroke related injuries and death. This statistic not only applies to humans, but to canines as well, who have similar body temperature thresholds. Recent studies have demonstrated that serum histones, released after cell death from heat stroke, play a role in heat stroke related injuries and death. This proposal aims to determine the severity of the effects caused by serum histone release after heat stroke by exposing selected canine cell lines to cell lysate and purified histones H2A, H2B, H3, and H4, which have been found to be …
Relations Among Maternal And Paternal Behavior And Children's Stress Biology, S.K. Jiaming Lin, Stacey N. Doan, John Milton
Relations Among Maternal And Paternal Behavior And Children's Stress Biology, S.K. Jiaming Lin, Stacey N. Doan, John Milton
Scripps Senior Theses
Parenting behavior has been shown to have a wide range of effects, influencing children’s psychological and biological stress outcomes. Most research focuses on maternal parenting behaviors, with few studies observing the effects of paternal behaviors or the influence of both parents on their children. In this study, the relationship between maternal and paternal parenting behaviors was examined in its association to predict children’s cortisol levels. Cultural differences in parenting styles was also observed. American (N=86) and Chinese (N=97) families participated in the study, with parents reporting their behaviors. Children’s cortisol was collected during a stressor task and correlational analysis was …
Investigating Neurogenesis As A Veritable Epigenetic Endophenotype For Alzheimer's Disease, Layne Wells
Investigating Neurogenesis As A Veritable Epigenetic Endophenotype For Alzheimer's Disease, Layne Wells
Scripps Senior Theses
Alzheimer's disease (AD) is the most common neurodegenerative disease, characterized by progressive amyloid plaque aggregation, neurofibrillary tangles, and cortical tissue death. As the prevalence of AD is projected to climb in coming years, there is a vested interest in identifying endophenotypes by which to improve diagnostics and direct clinical interventions. The risk for complex disorders, such as AD, is influenced by multiple genetic, environmental, and lifestyle factors. Significant strides have been made in identifying genetic variants linked to AD through the genome-wide association study (GWAS). It has been estimated in more recent years, however, that GWAS-identified variants account for limited …
Put Your Money Where Your Mouth Is: Reforming Organized Dentistry To Address Persistent Oral Health Disparities In The U.S., Aparna Chintapalli
Put Your Money Where Your Mouth Is: Reforming Organized Dentistry To Address Persistent Oral Health Disparities In The U.S., Aparna Chintapalli
Pomona Senior Theses
The importance of oral health has been largely neglected from the conventional standards of healthcare in terms of public understanding & prioritization, the industrial infrastructure, and the scope of prevention & early-intervention services. Its adjunctive locus to the field of medicine has lead to the bifurcation of the oral cavity from the rest of the human body. As a result of this divide, there have been multiple factors that have allowed socially stratified oral health outcomes to manifest. This thesis examines the determinants of oral health disparities through a multidisciplinary lens (i.e. biology, public policy, infrastructure), and offers evidence of …
Healthy Skepticism: The Relationship Between Funding Source And Conclusion In Nutrition-Related Scientific Articles On Saturated Fat, Lili Muskal
CMC Senior Theses
Recently published scientific articles have led to mixed nutritional advice on dietary saturated fatty acids. Lesser et. al (2007) identified that mixed conclusions in scientific articles on sweetened beverages might be attributed industry funding, as articles funded by the beverage industry are four to eight times more likely to report conclusions in favor of the sponsor’s products. This thesis applies Lesser’s methods to determine whether industry funding influences the inconsistent conclusions on saturated fatty acids. This thesis analyzes 100 articles on foods high in dietary saturated fatty acids. While studies with food industry funding are more likely to produce favorable …
