Aqueous-Based Associated Solvents For Protein And Peptide Fractionation And Protein Purification, Sajad Tasharofi

Chemistry & Biochemistry Dissertations - Archive

The focus of this dissertation is studying capabilities of a novel two-phase system in enhancing protein identification in the whole-cell proteomics studies. In this document, two types of biphasic systems have been used for two different purposes. The first type of biphasic system is formed by the addition of 1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) to the aqueous solutions of water-miscible organic solvents. A combination of HFIP, organic solvent, and water forms a two-phase system in spite of the fact that every solvent pair in the three-component system is miscible and forms homogeneous solutions in water. This biphasic system is called Fluoroalcohol-Organic Associated Solvent …

Total Synthesis Of Imidazole-Containing Β-Carboline Alkaloids And Pyrrole-Imidazole Alkaloids, Moumita Singha Roy

Chemistry & Biochemistry Dissertations - Archive

The first part in this dissertation focuses on the development of an enantioselective total synthesis of villagorgin A, from another natural product haploscleridamine. Haploscleridamine was targeted first as it was thought that a successful approach to this family member would permit access to the other congeners through minor modifications, including conversion to villagorgin A. Moreover, villagorgin A has just one additional carbon atom compared to haploscleridamine, the introduction of which can be envisioned through a Pictet-Spengler reaction with formaldehyde. On completion of the haploscleridamine synthesis, attention was turned to the brominated congener, lissoclin C. Lissoclin C can be accessed from …

Evaluation Of Geotechnical Parameters Of Soil Using Electrical Resistivity Imaging, Md Asif Akhtar

Civil Engineering Dissertations - Archive

Electric resistivity imaging (ERI) is an effective non-destructive and rapid measuring way of obtaining continuous soil subsurface resistivity profiles. An ERI technique can be used to identify moisture variations and soil heterogeneities in an area. Thus, ERI is becoming a popular tool in geotechnical (FHWA, 2015)engineering; however, it only provides qualitative information at the current time. Using qualitative images, it is challenging to extract quantitative geotechnical information, such as the type of soil, moisture content, degree of saturation, and atterberg limit, of the subsurface. Several studies have described the electrical resistance of soil as a function of pore fluid conductivity …

Development Of New Techniques To Dissect The Genetic Basis Of Population-Level Variation Of Recombination Rates In The Daphnia Model System, Swatantra Neupane

Biology Dissertations - Archive

We know very little about the determining genetic factors that control the recombination events within a genome. Moreover, the cause of recombination rate variation in population-level remains poorly understood, especially in non-mammalian species. The scarcity of population-level recombination rate data makes pinpointing genetic loci responsible for recombination rate variation even more challenging. Due to a lack of population-level recombination data, this hypothesis remains untested mainly in natural systems, like Daphnia. In response to the limitation of genetic tools used to dissect the genetic determinant of a trait in Daphnia, we put an effort to address these shortcomings in the Daphnia …

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Background: Throughout the aging process, people experience changes in functional ability and such changes can happen in physical and mental functions. As a result, older adults develop limitations in their capabilities to perform daily activities. Although many studies have done to identify functional limitations for elderly, many older adults still face negative consequences in daily living conditions due to their functional declines. One of the possible causes may be a lack of feedback or participations of elderly users in the design process. Other reason could be a lack of consideration to identify the needs for a specific task associated with …

The Effects Of Hyperbaric Oxygen Therapy On Pain Thresholds And Anxiodepressive Behaviors In A Pre-Clinical Fibromyalgia Pain Model, Cassie Mae Argenbright

Psychology Theses - Archive

Fibromyalgia (FM) is a chronic, widespread pain disorder generally of a non-inflammatory nature. FM has many known affective and cognitive comorbidities, including fatigue, sleep disturbances, cognitive deficits, and mood disturbances. As a result, FM treatment approaches are mixed in nature and lack a robust characterization that address symptoms on a sensory, affective, and cognitive level. However, there is promise in the implementation of hyperbaric oxygen therapy (HBOT) for alleviating fibromyalgia pain and comorbidities, despite no work investigating the efficacy of this treatment in prominent preclinical FM models. Thus, this project aims to investigate the affective components, specifically anhedonia and anxiety, …
