Approximately 33% of all current pharmaceutical medications discovered between 1981 and 2014 are either natural products or derived from natural products (Newman and Cragg 2016). The process of isolating specialized metabolites from medicinal plants has led to the development of particularly important medicines worldwide (Rakotomalala, Agard et al. 2013) such as Taxol® from Taxus brevifolia Nutt. (Taxaceae) and salicylic acid from the bark of Salix spp. This research is composed of five chapters; the …
When Men Are The Victims: Factors Affecting Rape Victim Blame & Bystander Aid, Shilpa Boppana
When Men Are The Victims: Factors Affecting Rape Victim Blame & Bystander Aid, Shilpa Boppana
Electronic Theses and Dissertations
Rape is a widespread problem, particularly on college campuses. While most research has focused on female victims, male victimization is more common than previously thought. Studies reveal that gender may play an important role in rape myth acceptance, as male victims of rape committed by female perpetrators are often perceived as more responsible for being raped and less traumatized than in cases with male perpetrators. Rape myth acceptance is associated with victim blame, as individuals who accept rape myths are more likely to attribute responsibility to rape victims for the assault. Rape myth acceptance and victim blame both influence bystander …

Novel Acetylcholine Chloride Based Water Immiscible Deep Eutectic Solvent: Formulation, Characterization And Application In Drug Solubilization, Shiksha Subedi
Electronic Theses and Dissertations
Deep eutectic solvents (DESs) are the emerging class of new and inexpensive solvents composed of two or three safe components capable of self-association through hydrogen bond interaction. The depression in the melting point characterizes DESs compared to those of the individual components. These solvents have properties like the traditionally used ionic liquids (ILs), but they can offset the significant drawbacks of ILs, such as biodegradability, toxicity, and complex synthesis. Due to these remarkable advantages, the research in DESs is increasing exponentially. However, current deep eutectic solvents still have limitations to apply to the real chemical industries due to hydrophilicity and …
Viral And Immune Studies On Bovine Viral Diarrhea Virus (Bvdv) In Bovine Species, Karim Abdelsalam
Viral And Immune Studies On Bovine Viral Diarrhea Virus (Bvdv) In Bovine Species, Karim Abdelsalam
Electronic Theses and Dissertations
BVDV is a major pathogen of ruminants that causes immune dysfunction and lead to secondary bacterial infection. The underlying mechanism of this dysfunction is not well understood. Based on previous results, we believe that macrophages play a central role in BVDV-associated immune dysfunction. Previously, we have shown that the infected monocyte-derived macrophage (MDM) supernatant of the high virulent strains of BVDV significantly induced lymphocyte apoptosis. In the current study, we performed experiments to identify the apoptotic factors in the infected MDM supernatants in vitro. Also, we have extended our investigation to include testing the impact of infected macrophages on neutrophil …

Electronic Theses and Dissertations
Flavonoids are a group of polyphenolic compounds, with established antioxidant properties, that are present ubiquitously in plants, fruits, and vegetables. Their universal presence in nature is evident by the fact that more than 4000 types of flavonoids have been identified till date. Additionally, they have also become part of the daily diet through consumption of fruits such as berries, grapes, pomegranate, and cherries, and vegetables such as onions, kale, and eggplant. High levels of flavonoids are also consumed through beverages such as tea and red wine. Numerous studies have demonstrated that a diet rich in flavonoids decreases the incidences of …
Comparison Of Software Packages For Detecting Differentially Expressed Genes From Single-Sample Rna-Seq Data, Rong Zhou
Electronic Theses and Dissertations
RNA-sequencing (RNA-seq) has rapidly become the tool in many genome-wide transcriptomic studies. It provides a way to understand the RNA environment of cells in different physiological or pathological states to determine how cells respond to these changes. RNA-seq provides quantitative information about the abundance of different RNA species present in a given sample. If the difference or change observed in the read counts or expression level between two experimental conditions is statistically significant, the gene is declared as differentially expressed. A large number of methods for detecting differentially expressed genes (DEGs) with RNA-seq have been developed, such as the methods …
Revegetating Salt-Impacted Soils In The Northern Great Plains, Abigail P. Blanchard
Revegetating Salt-Impacted Soils In The Northern Great Plains, Abigail P. Blanchard
Electronic Theses and Dissertations
In the northern Great Plains (NGP), an estimated 10.6 million hectares of land are affected by naturally occurring salt-impacted soil. Naturally occurring salt impaction results when rainfall causes salts in parent material to move upward through the soil profile and remain in the root zone causing osmotic and ionic stress, negatively affecting seed imbibition, germination, and plant growth. Common methods to remediate saltimpacted soils were developed in the irrigated soils of the Southwestern U.S., are ineffective in the non-irrigated soils of the NGP, and can exacerbate the problem. Therefore, new methods to remediate salt-impacted soil in the NGP are needed. …
