▼ At the heart of the chromatography technique, the stationary phase is the essential component that dictates multiple aspects of the separation process. Diverse chemistry of the stationary phases, in combination with the choice of appropriate base support materials, allows chromatography to be used in a wide range of applications ranging from the high-performance separations of trace analytes in complex biological samples for chemical detection and quantification to the large-scale purification of a recombinant protein from a complex media. Traditional chromatographic stationary phases mostly utilize porous materials for the high surface area and versatility for chemical modification. However, in many cases, these materials suffer from high operating back-pressure and inefficient mass transfer. Joining the efforts to investigate alternative phases, Marcus research group (Clemson University) has investigated the potentials of capillary-channeled polymer (C-CP) fibers for the past 15 years. These fibers are characterized by eight capillary channels running down the length of the fiber, allowing the fibers to interdigitate to form well-aligned micrometer-sized channels when packed into a column format. It is the unique shape that allows separations to be conducted at high linear velocities (>75 mm s−1) with high column permeability (<0.14 MPa cm−1). The highly efficient fluid movement through the narrow channels composed of non-porous C-CP fibers gives rise to favorable mass transfer rates, facilitating fast protein separations and processing. Moreover, another advantage of C-CP fiber supports over other commercial sorbents is that these fibers are quite stable over a wide pH range and are fairly inexpensive (<$ 100 lb−1). Additionally, packing a C-CP fiber column is a simple process that can be conveniently performed without any special equipment.
The concepts of using natural and synthetic polymer fibers as chromatographic stationary phases are not new. Potential advantages cited include low costs, ease in column fabrication, low operation backpressure, facile solute mass transfer, and a general ease of tailoring fiber surfaces to affect high levels of chemical specificity. There have been several surface modification techniques reported for polymer fibers in the literature. However, many of these modification methods can be detrimental to the physical properties of the polymer by destroying the polymer backbone. In order to further exploit the advantageous fluidic properties of C-CP fiber columns without compromising the fiber integrity, milder modification approaches have been a focus of this group recently, including covalent coupling and direct ligand adsorption methods. The research studies reported in this work focus on the development of functionalized C-CP fiber for a variety of
affinity chromatography applications. The ultimate goal is to investigate non-invasive modification schemes that do not compromise the mechanical strength and fluidic properties of C-CP fibers.

▼ Cadherins are transmembrane glycoproteins that are involved in maintaining integrity of cell junctions, morphogenesis, cell sorting and many more important biological processes. In my thesis, I have focused on studying the binding
affinity of a class of cadherin superfamily called N-cadherins. Prior studies have demonstrated that N-cadherins can promote neuronal growth and axonal regeneration in vitro. Moreover, there is a growing interest in development of small molecules targeting N-cadherins and designing of therapeutic agents to promote cell survival and axonal regeneration as well as inhibit cadherin mediated signaling. For in vitro studies, knowing the minimum fragments of adhesive binding domain i.e. extracellular domains that can recapitulate the wild type N-cadherin binding functions can help develop designing of biomaterials and platforms to study N-cadherin interactions. Two dimensional
affinity measurements reveal probability of stable bond formation during homophilic and/or heterophilic interactions between cadherins via extracellular domains. In order to determine the minimum fragment of the extracellular domain required for binding to mimic full length cadherin and wild type cadherins expressed on cell surfaces, Micropipette Aspiration Assay (MPA) was performed. Using N-cadherin as a model for classical cadherins, the binding
affinity of full length N-cadherin (N-cad EC1-5) expressed on a test cell surface (here, mesenchymal stem cell (MSCs) with the first two extracellular domains (N-cad EC1-2) and the binding pocket sequence HAVDI peptide and full length N-cadherin (N-cad EC 1-5) were measured by this assay. The first chapter of my thesis, I talked about the structural differences of most studied cadherins E and N-cadherins and briefly described the importance of the flanking amino acid of binding pocket sequence HAVDI in N-cadherins. In the following chapter, I describe the experimental approach for determining the binding affinities of N-cadherin fragments and compared the 2D binding
affinity results with that of the full length wild type N-cadherin expressed on MSCs. Surprisingly, the results of the study revealed that there is no significantly difference in binding
affinity between N-cad EC1-2 and N-cad EC1-5 as well as HAVDI and N-cad EC1-5. The MPA studies were conducted with both wild type MSCs expressing N-cad EC1-5 as well as RBCs modified with N-cad EC1-5. However, there is a lower binding
affinity between E-cadherin and HAVDI than that between N-cadherin and HAVDI. These results demonstrate the importance of the flanking amino acids next to HAV sequence in cadherin specificity as well as the possible application of small peptide sequence HAVDI as a novel antagonist in processes involving N-cadherin mediated adhesion.

▼ During the antibody affinity maturation process,
changes to the immunoglobulin genes are initiated by the B-cell
specific enzyme activation-induced cytidine deaminase (AID). These
changes are randomly generated and produce antibodies with
different affinities for the antigen. In mammals, this process
occurs in highly regulated environments known as germinal centres
(GCs). Although conventional GCs are absent in fish, AID expressing
B-cells are found in close proximity to pigmented myeloid cells
called melano-macrophages (MMs). Previous in vivo work suggested
that MMs have functions consistent with those of follicular
dendritic cells (trapping antigen) and tingible body macrophages
(phagocytosis of apoptotic cells) found in the GC. Quantitative PCR
used to assess gene expression of pro- and anti-inflammatory
cytokines in MMs under in vivo and in vitro conditions revealed
that these cells may have different roles in the immune response
depending on their anatomical location.

▼ We demonstrate the functionalization of a highly
ordered porous molecular sieving matrix created by colloidal
self-assembly (CSA) of 2 micrometer diameter silica particles in
microfluidic chips, for highly efficient immuno-capture of viruses.
By tuning the particle size, with appropriate surface chemistry, we
can easily match the pore size which could maximize biological
species-particle wall collision, leading high capture efficiency.
The ordered uniform lattice of pores, which are 15 % of the size of
the particles used, should prove ideal for the capture of viruses
(on the 50-150 nm scale in size). We report on characterization of
capture beds with 300 nm pores. These beds were used to detect
fluorescein using immobilized anti-fluorescein on the bed, and also
to capture and detect type-5 adenovirus in suspension, and in
infected cells using appropriate antibodies. We demonstrate the
performance of the concept using a fully packed column for
fluorescein immunoassay. We used 2 μm carboxylated silica particles
self-assembled into a 6 mm long-bed, modified with EDC/NHS, and
immobilized anti-fluorescein antibody or type-5
adenovirus-recognizing antibody. An electric field was applied to
utilize electro-osmotic flow as the solvent pumping force. A 4.51
nM fluorescein solution was captured by immuno-affinity using
anti-fluorescein antibody, and then released with an eluent to an
empty downstream analysis region to give a very large signal,
providing a positive control. Similar experiments were performed
with type-5 adenovirus, demonstrating detection at a concentration
of 8.3 × 103 viral particles (VP) per milliliter. Adenovirus in
celllysate was also detected in this microchip, with the lowest
concentration detectable at 1.5 × 103 PFU/mL. Combination of
advanced biological detection methods with microfluidics based
extraction and concentration techniques has tremendous potential
for realization of a portable, cost effective and sensitive
pathogen detection system. Taking advantage of the unique fluid
flow characteristics of CSA structures on an even smaller scale
than employed here, faster, more sensitive and more economical
capture and pre-concentration techniques for diagnostic assays for
a wider range of analytes can be developed.

▼ Alzheimers sjukdom (AD) är den vanligaste formen av demens och påverkar miljontals människor världen över. Förekomst av senil plack och tangles in hjärnan hos personer med AD har varit ett känt faktum sedan början av 1900-talet. Flera studier gjorda under de senaste åren har påvisat en kopplling mellan AD och Diabetes, då försämrad insulin-signalering och nedbrytning av glukos påverkar flera av de molekylära förändringar som uppvisas i AD. I det här projektet använde vi oss av immunofluorescence för att studera uttryck och lokalisering av två transkriptionsfaktorer involverade i nedbrytning av glukos; NPAS3 och RFX3, i hjärnbarken hos patienter med AD, Lewykroppsdemens (DLB) hälsosamma kontroller. Intensiteten på infärgningen av NPAS3 och RFX3 visade inte mängden protein och kvantifierades med algoritmer skrivna i ImageJ. Infärgningen av NPAS3 och RFX3 visade inte på någon signifikant skilland mellan de tre kohorterna och för att förstå mer om deras roll i nedbrytningen av glukos och om det kan påverka AD, måste både infärgnings- och kvantifieringsprocesserna använda i detta projekt optimeras.
Alzheimer's disease (AD) is the most common form of senile dementia. affecting millions o people worldwide. Beta amyloid plaques and neurofibrillary tangles are known to be part of AD pathology since the early nineteen hundreds. In recent years evidence showing that impairments in glucose metabolism can initiate plaque- and tangle formation, as well as several of the other degenerative mechanisms taking place in the AD brain, suggests a potential connection between Alzheimer's disease and Diabetes. Here we used immunofluorescence to study expression of two transcription factors involved in regulation of glucose metabolism; NPAS3 and RFX3. Expression of NPAS3 and RFX3 was investigated in temporal cortex from patients with AD, Dementia with Lewy bodies (DLB) and non-demented age matched controls. The intensity of the immunofluorescent stainings was assumed to be proportional to the amount of stained protein and was quantified in ImageJ. This explorative study did not reveal a significant difference between groups and staining- an quantification procedures would have to be optimized in order to get a clearer understanding about the role of NPAS3 and RFX3 in glucose metabolism, and if that could affect the progression of AD.

▼ Phenotypic screening of drug molecules relies on the generation of a specific response; however the means by which this is elicited often remains unknown. Affinity chromatography is a valuable tool in the discovery of drug binding partners and may even allow the elucidation of the wider interactome of the initial drug target. The introduction of easily cleavable linkers and affinity-independent elution protocols to affinity chromatography is of current interest, since they render the technique much more adaptable with respect to the characterisation of biologically active species of interest. This thesis details the application of a novel azobenzene linker developed by the Hulme group for use in affinity-independent chromatography. The first chapter reviews recent developments in affinity chromatography and describes the synthesis of an affinity linker toolbox with both affinity-dependent and affinity-independent linkers. These linkers are functionalised with an azide moiety for use in CuAAC coupling to alkynyl derivatives of bioactive small molecules and have been modified to include photoreactive groups giving a series of linkers for use in the identification of less abundant, or low affinity, proteins. The first drug investigated, anisomycin (ANS), is a small molecule which was initially introduced as an antibiotic drug (Flagecidin). At nanomolar concentrations ANS has been shown to affect the mitogen activated protein kinase (MAPK) pathways; downstream effects of these pathways are thought to play a role in a range of pathological disorders such as Alzheimer’s disease, cancer and spinal muscular atrophy (SMA). ANS is thus a candidate for drug repurposing. Although the downstream effects of MAPK/SAPK pathway activation induced by anisomycin are well-documented, the cellular target has yet to be revealed. Previous work by the Hulme group has shown that the N-propargyl anisomycin derivative (I) retains the biological activity of the lead compound ANS. Thus to evaluate the cellular protein targets, N-propargyl ANS (I) was coupled onto the linker toolbox to create an ANS affinity probe library as described in chapter 2. The second drug investigated, fingolimod, was introduced as an immunomodulating drug (Glienya) for the treatment of multiple sclerosis (MS). This small molecule has also been shown to have anti-cancer properties in a range of cancer cell lines; however the precise mechanism by which this is effected is unknown. Literature precedent shows that terminal modification of fingolimod generates analogues which still retain biological activity. Thus a novel fingolimod alkyne derivative (II) was synthesised and used to create an affinity probe library as described in chapter 3. Chapter 4 describes affinity pull-down experiments conducted with the aim of finding the protein target(s) of ANS and fingolimod, using the affinity probe libraries generated in chapters 2 and 3. This chapter concludes with a discussion of the implications of these findings and directions for future study.

▼ Chapter 1. A brief history of the use of ionizing radiation for cancer therapy is presented, as the motivation for modern clinical investigations on alpha therapy and the use and development of bifunctional chelators in targeted medicine. Recent studies on targeted therapy with alpha-emitters, such as 223Ra and 227Th, are described. The chemistry of Th(IV) is presented with a survey of important coordination compounds, with special emphasis on those developed by the Raymond group.Chapter 2. The rational design of a ligand as a suitable bifunctional chelator for 227Th therapy is described in the context of ligands developed by the Raymond group for actinide sequestration. A novel Φ ligand topology incorporating macrocyclic and pendant terephthalamide binding groups aims to address the kinetic and thermodynamic requirements of targeted alpha therapy. The syntheses of the model ligands Φ(2,2)moeTAM and Φ(3,3)moeTAM are detailed, from which a derivative of Φ(2,2)moeTAM is developed. Functionalization of a pendant terephthalamide of the model ligand gives the asymmetric bifunctional chelate Φ(2,2)NBuTAM via the strategic use of protecting groups.Chapter 3. The evaluation of the solution thermodynamic behavior of Φ(2,2)moeTAM is extensively detailed. The protonation constants of the ligand and its affinity for Th(IV) is measured by spectrophotometric titration. The thorium complex was found to have a remarkably high thermodynamic stability, with a formation constant of 1054, surpassing the stabilities of previously measured complexes. Efforts to elucidate the effects of the Φ topology on the coordination of Th(IV) using thermodynamic studies of the linear analog 3,4,3-LiMeTAM as well as the shape analyses of the crystal structure of Th[Φ(2,2)moeTAM] are described. The surprising geometry adopted by Φ(2,2)moeTAM in the thorium complex relative to its structure as the free ligand is further investigated with DFT studies.Chapter 4. While the measurement of the thermodynamic parameters of the thorium complex provides an assessment of its inertness, its formation kinetics are also of paramount importance due to the inherent time sensitivity of radiotherapeutic agents. Difficulties encountered in preliminary kinetic experiments with existing octadentate ligands and Φ(2,2)moeTAM lead to the use of indirect kinetics. Dye-displacement kinetic studies with the Φ ligands, 3,4,3-LiMeTAM, and the aminocarboxylic acid ligands provide a useful qualitative comparison of the rates of complexation of these ligands with Th(IV). Φ(2,2)moeTAM is observed to be a much more rapid chelator than the prevailing DTPA and DOTA, and its association (a second-order reaction with a rate constant of k2 = 1.8(1) x 104 M-1s-1) can be directly measured using stopped-flow kinetics. Chapter 5. The application of Φ(2,2)moeTAM toward the coordination of the lanthanide analogs cerium and praseodymium is presented. The crystal structure of the Ce(IV) complex with Φ(2,2)moeTAM is isomorphous to…

Beginning Teachers Finding Support Through an Online Teacher Network: Affinity Lear-NING.

▼ Teacher attrition remains a concern in the field of education; while this is not a new problem, the reasons why teachers tend to leave the profession are concerning. Recently, the Carnegie Foundation for the Advancement of Teaching (2014) found that nearly one third of all teachers leave the profession within their first three years; many cited a lack of administrative and professional support as a major factor in their decision to seek alternative employment. “The problem takes many forms, including the feeling of being isolated from colleagues, scant feedback on performance, poor professional development, and insufficient emotional backing by administrators” (p.7). While there is no replacement for a solid teacher induction program, it is clear that teacher educators need to find alternative and expansive ways to provide intellectual and emotional support to new teachers as they enter the profession, helping them focus not only on their pedagogical and content knowledge skills, but also on nurturing their emerging and constantly evolving teacher identifications. One way that teachers are able to achieve this level of additional support on their own, bridging the gap from the University to their initial in service positions (supplementing what can sometimes be less than ideal professional development), is to turn to online teacher communities, or what I term online teacher
affinity spaces.
The purpose of this study was to investigate the types of support beginning teachers perceive they obtain from voluntary membership within a particular online teacher
affinity space called The English Companion Ning (EC Ning). Using a qualitative ethnographic approach, I sought to identify the types of discursive practices that emerge as beginning teachers participate in the content-specific online space. It incorporates sociocultural and social learning theories (Gee, 2006; Lave and Wenger, 1991; Wenger 1998) to explore how beginning teachers, often considered legitimate peripheral participants, display patterns of membership and interaction, as well as how they position and identify themselves as beginning teachers within the discussions they engage in.
The results of this study suggest the potential of online teacher
affinity spaces to support beginning teachers, both professionally and emotionally. A salient finding is that beginning teachers tend to take up various degrees of participation in the EC Ning and this can be closely tied to the levels of support they experience at their schools of employment. In addition, the EC Ning displayed elements of
affinity space that provided beginning teachers the opportunity to conduct important identity formation and experimentation. The utilization and implementation of these types of spaces as supplemental support, as early on as in teacher education programs, have the potential to provide beginning teachers with the reinforcements they need in order to survive and thrive during their first years of teaching.

▼ Public institutions of higher education have faced repeated financial reductions over the past decade. The cumulative effect of reductions has necessitated public institutions re-examine funding models and funding alternatives that allow the institution to thrive. Alumni are the living endowment of the institution and are offered opportunities for involvement with their alma mater throughout their lives. The purpose of this study is to explore the association of specific university experiences that contribute to a strong sentiment of
affinity of undergraduates for the institution. It further explores the experiences that appear to be most significant in developing university
affinity at the undergraduate level. Current students enrolled at a public research extensive university in the Midwest were surveyed to determine if a relationship exists between university experiences and university
affinity. This study also examined the differences in student characteristic information and university
affinity. Using multiple regression to analyze the results, four university experience constructs were found significant. They include; student service opportunities, student service staff, initial impressions of the institution and extracurricular involvement. The analysis of student characteristics did not have significance in this study. Examining the experiences, perceptions and demographics of current students and what contributes to the concept of
affinity is critical in the pursuit of alumni who want to be connected and committed to the institution.

▼ Affinity maturation increases the
affinity of B-cell derived antibodies to their cognate antigens. In this study, we characterized the kinetic, structural, dynamic and thermodynamic evolution of antibodies during
affinity maturation. Through single B-cell cell sorting, paired heavy and light chain sequencing, phylogenetic analysis, antibody expression, and physicochemical characterization, we were able to longitudinally analyze the stages of
affinity maturation of anti-PA (B.anthracis protective antigen) antibodies. Following repeated immunizations, we observed up to an 10,000-fold increase in antibody
affinity, mainly through a decrease in the off-rates. For detailed maturation analysis, we chose three antibodies lying along a single clonal branch – the clone’s unmutated common ancestor (UCA), a medium
affinity antibody (MAAb) appearing after second immunization, and a high-
affinity antibody (HAAb) appearing after third immunization. Most of the mutations that occur between the UCA and HAAb resulted in key changes to structural conformation. In particular, mutations change residues in the CDR-H3 region inducing the folding of the CDR-loops into a conformation that is more complementary to PA. This advantageous new antibody conformation is preserved in the unbound state, indicating that though the UCA and MAAb appear to use an induced fit and/or conformational selection mechanism, the HAAb is more rigidly lock-and-key. Thermodynamic results support this interpretation. In the first maturation step from UCA to MAAb, enthalpic improvement indicates optimization of noncovalent interactions. The second step from MAAb to HAAb predominantly involves entropic improvement by which the advantageous conformation made accessible in the first step is made more dominant via the narrowing of effectively accessible conformations, which allows better contact with PA. This is also reflected by a less significant improvement in the enthalpic component of PA-binding. Studies examining the evolving protein-dynamic characteristics further support this interpretation. In summary, we observed that a single energetic component is not responsible for increased
affinity in the maturation pathways we studied. From UCA to MAAb,
affinity increases through optimization of noncovalent interactions. From MAAb to HAAb,
affinity increase is achieved through changes that stabilize the favorable conformation in the unbound state. A better understanding of
affinity maturation can have implications for antibody engineering and vaccine development.

▼ Biomarkers are molecules whose presence is indicative of some biological phenomena, such as disease or infection. Since their discovery, biomarkers have played a vital role in the development of prognostic and personalized medicine. Traditionally, biomarkers are detected via various assay formats using engineered antibodies. The molecules, however, have a number of inherent limitations. Recombinant
affinity reagents, however, have many advantages over traditional monoclonal antibodies: they are renewable, highly modifiable, easy to share, and require less time and resources to produce. The work herein describes two technological advances that could change the paradigms for reagent- and assay-development.

▼ Purpose: To identify the relevance ethnocentrism, affinity and product country-image (the
three theory effect affectionately called “the enchilada effect” by the authors) have on the
consumers’ decision-making process as well as their effect on the consumers’ preferences for
certain product attribute importance and types.
Problem: In modern society most marketplaces around the world are full of foreign products.
The importance ethnocentrism and the country of origin (COO) effect have on the consumers’
decision process has already been studied and identified on several researches along several
decades. This mentioned, the authors think not only ethnocentrism, but also affinity and PCI
might have an effect on this decision process as well. Therefore, they believe this to be an
interesting and important consumer behavior phenomenon to investigate. Further, they want
to identify how much these theories influence the consumers in two areas: first, the relative
preferences of 8 attributes importance (price, quality, design, weight, energy saving, capacity,
material, and HDD storage capacity) distributed in 4 product categories (laptops, refrigerators,
bicycles and shoes); and second, their effect on consumers’ preferences over two types of
product versions (low-end versus high-end) that differ in price and their added features with
the basic price-quality relationship i.e. the more expensive the better it is.

▼ The epigenetic post-translational modifications (PTMs) of histone proteins are numerous and have an important role in regulating cellular development. Molecular recognition elements that can bind directly to epigenetic PTMs have previously been developed. The most synthetically accessible of these are a family of molecules called monoaryl-trisulfonate calix[4]arenes. The initial goal of this thesis was to develop research tools consisting of these asymmetrically-derivatized calixarenes immobilized onto a solid resin for the purpose of enrichment of PTM-bearing species. Seven novel resin-immobilized calixarene reagents were created and employed in batch-wise pulldown experiments, as well as chromatographic separations. These experiments produced mixed results: poor efficacy was demonstrated in batch-binding experiments but total separation of certain PTM bearing peptides was achieved in a chromatographic approach. During these studies, a subset of these calixarenes were found to undergo self-association in water in a fashion not previously observed for calixarenes. Secondary goals of the thesis were to create new examples of this self-associating motif, and to characterize and develop structure-function relationships for their assemblies. Eight new self-associating calixarenes were developed and characterized extensively by 1H NMR, isothermal titration calorimetry (ITC), and X-ray crystallography. Self-association was shown to be enthalpically driven with Kd values ranging from 1-20 mM. The dimeric assembly behaviours were remarkably consistent across many different family members, and were shown to persist even in highly competitive media like mock blood and urine. This system represents a novel class of ordered calixarenes assemblies that operate in biological media.

▼ This study examined whether the ???in-group advantage??? (Elfenbein & Ambady,
2002a) exists in Caucasian American and African American women???s ability to detect
cues of paternal investment from photographs of males with neutral facial expressions
(Roney, 2006). It was hypothesized that 1) females would display a general ability to
detect cues of paternal investment from photographs of neutral male faces and 2)
Caucasian American females would more accurately predict interest in infants of males in
their own respective ethnic group, thus displaying the in-group advantage. The third
hypothesis took a bidirectional approach, proposing that either 1) African American
females, as opposed to Caucasian American females, would display this ability to a
higher degree, or 2) African American females would be less accurate at determining
interest in infants in either of these groups, including their own. Sixty-two Caucasian
American females and 51 African American females served as judges in the study. They
viewed one of two versions of a PowerPoint presentation wherein 15 Caucasian
American and 15 African American male photographs were presented in succession and
were asked to rate each target in terms of his
affinity for children. Average judge ratings
were correlated with targets??? scores on a measure of
affinity for children (Maestripieri &
Pelka, 2002) to assess the accuracy of judges??? ratings. The results of the current study did
not support either hypothesis. The absence of significant findings was attributed mainly
to methodological differences between this study and that of Roney et al. (2006).

▼ The proteome is perhaps the most functional operating machinery for almost all biological processes, serving as the bridge to link the genome and phenotypes. The proteome undergoes dynamic changes in terms of the abundance or interactions, responding to the environmental stimuli. Understanding this dynamic of protein alterations is the key to delineate critical biological mechanisms. Mass-spectrometry-based proteomics is a powerful tool to systematically monitor the heterogeneous alterations of the proteome, including the changes of abundance, modifications and interactions. In this dissertation, a research project was built upon current proteomics approaches to solve the issues regarding to the sample preparation and data analysis that would help propel this approach to better address certain questions in environmental microbiology and molecular biology. In the first study, we have designed an experimental method that efficiently removes humic acids prior to proteolytic peptide measurement, thus addressing one major challenge associated with soil microbiome proteome extraction and subsequent MS measurement. The second study was aimed at employing advanced proteomics approaches to better understand the microbial drivers of environmental mercury processes by using two model organisms: Geobacter sulfurreducens PCA and Desulfovibrio desulfuricans ND132. Our results elucidated the global proteome impacts caused by the deletion of mercury methylation essential genes hgcAB and revealed that deletion of hgcAB genes did not show significant impact on the microbial response to mercury addition. The third study focused on optimizing MS-based proteome approaches for characterizing protein-protein interactions. By coupling the rapid crosslinking procedure, affinity enrichments and high-performance MS measurements, protein-protein interaction can be captured and interrogated in a living cell by a time-resolved manner. Overall, the methods and results presented in this dissertation not only provides an enhanced sample preparation methodology for intractable samples (such as soils), but also demonstrates how this systems-biology approach can be utilized to characterize the basics of microbial physiology at a global proteome level as well as drilling down into specific proteins interactions.
The optimized methods and experimental/bioinformatics techniques described in this dissertation should be broadly extendable to proteome characterization/protein interaction examination in various systems.

▼ This dissertation explores the use of polymer affinity agents for the surface-enhanced Raman spectroscopy (SERS) detection of food safety targets. First, current molecular motifs used as affinity agents in intrinsic surface-enhanced Raman spectroscopy (SERS) sensors are reviewed. By comparing antibody, aptamer, small molecule, and polymer affinity agents, the largely unresearched potential of polymer affinity agents (chemical customization, tunable length, ease of production, opportunity for multiplexing) is highlighted. The first proof of concept work of this dissertation targets the detection of the bioterror agent, ricin B-chain (RBC) in water and liquid food matrices. An N-acetyl-galactosamine glycopolymer capture layer was designed and applied to create a SERS sensor. The sensing scheme’s detection limit (20 ng/mL) is well below that of the predicted oral exposure limit. The RBC was detected in two types of juice, and a computed normal Raman spectrum of the glycomonomer supports polymer–RBC intermolecular interactions at the functional group level. Subsequent work focuses on the translation of this sensing scheme from the detection of proteins to the detection of small molecules relevant to food safety. Because interactions between a small molecule target and a polymer affinity agent are less specific than those that were leveraged in the RBC work, the development of a rapid affinity agent screening method was deemed necessary. A potent carcinogenic metabolite of a fungal pathogen that can infect food and feedstocks, aflatoxin B1 (AFB1), was used as a model target. Seven homopolymers of nitrogen-inclusive poly(N-(2-aminoethyl) methacrylamide) (pAEMA) and their oxygen analogs, poly(2-yydroxyethyl methacrylate) (pHEMA) were synthesized to be evaluated as AFB1 affinity agents based on hypothetical hydrogen bonding interactions and optimal polymer length. An isothermal titration calorimetry (ITC) method was development for rapid affinity agent screening and good agreement was observed between the ITC results and follow-on SERS sensing experiments. A final polymer series (poly(N-acryloyl glycinamide), pNAGA) was designed for the capture of AFB1 and was used to explore the influence of polymer molecular weight (2.0 – 5.2 kDa), attachment chemistry (thiol vs. trithiocarbonate), and order of addition (pre- vs. post- functionalization of the substrate) on the sensitivity of AFB1 detection. The best polymer chain length (pNAGA22), anchoring chemistry (thiol), and polymer/toxin assembly scheme (in-solution) allowed detection of 10 ppb AFB1 in water (below the FDA regulatory limit of 20 ppb), a hundred-fold improvement over SERS sensing without the pNAGA affinity agent. This dissertation concludes with the advantages, disadvantages, and future perspectives of polymers used as analytical affinity agents. Adjustment of surface attachment moieties, the use of crosslinkers with target affinity, and application to other signal transduction mechanisms are emphasized a potential areas for continuing work.

▼ The purpose of this thesis is to take the individual on a journey about what it is like to be engaged in radical anti-systemic activism in the 21st Century. Along this journey the reader will learn about the experiences of what it was like to join the Occupy movement"an anti-systemic movement that began in 2011"through an empirical analysis of learning about and practicing the anarchist(ic) characteristics of the movement"horizontal, non-hegemonic,
affinity and consensus-based ways-of-being as a part of your everyday lifeworld. This journey is not only informed by my own personal experience joining the Occupy movement, but it is also informed by my simultaneous experience of maintaining the role of a radical activist-scholar throughout the process. Accordingly, I will explore how this impacted my lifeworld both within and outside of academia, which informed the very framework, analysis, and outcomes produced in this thesis. This project was thus also designed to inform social science research"particularly that on social movements"by reflecting on both social roles experienced in this journey in order to cohesively make sense of the paradoxes created by engaging in discourses about, within, and for the Occupy movement. Of most importance, from an empirical and ontological experience as an Occupier and activist-scholar, this project will help to raise key questions about the frameworks to seek social justice utilized by contemporary anti-systemic social movements in the 21st Century"social movements that are now spreading around the globe.

▼ Approximately 90% of all therapeutic targets in the human proteome operate solely inside the cell, making them unavailable for recognition by antibodies which instead bind antigens presented on the exterior of the cell surface. To target the 90%, the human immune system utilises a class of binding proteins known as T-cell receptors (TCRs). These TCRs recognise peptide fragments sourced from proteins produced inside the cell that have subsequently been degraded and transported to the cell surface by the human leukocyte antigen (HLA, pHLA with peptide bound). TCRs are membrane bound and attached to T-cells and use their six complementarity-determining region (CDR) loops to bind antigenic pHLA molecules (i.e. peptides that come from protein antigens). TCR binding to pHLA molecules induces an immune response from the T-cell, which ultimately leads to the antigen presenting cells death. The capability of TCRs to identify antigens which are not naturally expressed on the cell surface (unlike antibodies) has helped drive the development of a new class of therapeutics that consist of a soluble, bispecific TCR engineered to bind a specific antigenic pHLA for the treatment of various diseases (such as cancers and viral infections). Natural TCRs bind with characteristically poor affinities (~μM) and half-lives (~seconds), which are undesirable properties for a therapeutic. The CDR loops on TCRs are therefore normally subjected to affinity maturation to produce TCRs with affinities in ~pM range for their target pHLA. This does however carry a significant risk in terms of safety, as the very large majority of peptides presented by HLA molecules are sourced from endogenous (i.e. healthy) proteins and must not be bound by the TCR in order to avoid the production of an autoimmune response on the healthy cells. These requirements for a highly specific TCR that binds with high affinity to its target pHLA is the primary motivation for this thesis, as herein, fundamental engineering principles for generating TCRs with these properties are determined and protocols to evaluate these properties are developed and demonstrated. This insight is obtained through combinations of structural analysis, molecular dynamics simulations and free energy calculations, providing an atomistic description of how this has occurred for several TCRs. Furthermore, we characterise how different peptide cargo can tune the molecular flexibility of the entire pHLA molecule, including regions distal from the HLA binding site. These findings suggest peptide dependant tuning of the HLA molecule may play a role in regulating the functional outcome of an immune response. Ultimately, this work and the principles identified herein will aid in the rational design of high affinity and high specificity TCRs as therapeutics for various diseases.

▼ The development of therapeutic antibodies has been revolutionary in the pharmaceutical industry due to the specificity of antibodies to a biological target and their ability to elicit a response that engages the immunological destruction of the target. As with all biologic pharmaceuticals, active antibody is lost in downstream production processes and long term storage due to intrinsic instability causing degradation and aggregation. Pharmaceutical formulations currently adopt an approach to reduce loss in aggregation through lyophilised product to be reconstituted only when in use, to large volumes appropriate for intravenous, or in some instances sub-cutaneous administration. This project explores avenues of identifying regions in the peptide structure of a model antibody (Trastuzumab) from which to improve intrinsic stability and improve affinity to its target. As many therapeutic antibody peptide structures have homologous constant regions, Adalimumab was used to show transferability and proof of concept with the modifications specific to improving antibody stability. Sites for modification were derived through in silico analysis of the crystal structures of antibody fragments. Trastuzumab and Adalimumab genes were cloned into suitable vectors to produce an optimised laboratory scale expression system. The modifications derived from in silico analysis were translated to Trastuzumab and Adalimumab through site directed mutagenesis. The mutant libraries were expressed for testing in vitro for stability and binding kinetics against their biological targets HER-2/TNF-a and Fcγ receptors. Our findings show that several of our rationally designed peptide modifications showed improvement in their targeted effect, and that can be translated to improving production and formulation strategies, as well as better treatment outcomes.

▼ This document seeks to elucidate the perceptual
quality of a note’s position in the diatonic scale, regardless of
its distance from a centric pitch. While some notes are leading
tones, I argue that all notes are leaning tones, some leaning up,
others down. In the first chapter, I introduce the idea of diatonic
position, following Lam’s (2019) concept defined by its intervallic
position in the scale, regardless of the prevailing tonal centrism.
I order these positions according to Browne’s (1981) concept of
interval contexts. The second chapter traces perceptual theories by
Hucbald, Guido, and Handschin, and compares and contrasts
Hansberry’s (2017) narrow definition of scale degree qualia with
the qualia of diatonic positions. I then cast the character of a
diatonic position as an orientation, notes leaning up or down based
on their diatonic position on the line of fifths. Chapter three
offers a visual representation of these diatonic positions, adding
a new layer of representation to our understanding. In chapter four
I use melodic subjects by Bach to model how we perceive these
positions as listeners by mapping intervals to a pitch wheel. The
resulting interval patterns are compared to the interval contexts
of each diatonic position to find possible matches. I continue to
compare the experience of hearing changes in scale degrees to
diatonic positions. Chapter five explores how we move from one
diatonic position to another. Tracing motion through the line of
fifths as well as diatonic scale space, I suggest a phenomenal way
to distinguish specific interval qualities, building on the
structural observation of diatonic scale theory. Finally, in
chapter six I explore to what extent the sound of a diatonic
position plays a role in the experience of resolution-tendency
qualia as described by Hansberry, separating the contextual
orientation of a note from its immediate sense of
resolution.

▼ Student involvement on their campus is a vital part of their experience in higher education. A lack of involvement and engagement can lead to a decreased sense of belonging on campus and in their chosen field of study. Researchers speculate that one reason students leave STEM is because students have not developed a strong perceived attachment to the field of science. One way that students may build this perceived attachment to science is through increasing their engagement and participation in science-based activities. By participating in science-based social organizations, students are exposed to new experiences they would not normally have during their coursework. The purpose of my study was to investigate how biology-based student organizations functioned as
affinity groups and how these groups influenced individuals’ perceived cohesion to science. I followed three biology-based student organizations, biological honor society, microbiology club, and wildlife club, over the course of one academic year to identify the extent they exhibited the characteristics of
affinity groups. After collecting and analyzing data from field observations, I found that all three groups exhibited the criteria of
affinity groups to various degrees. Through analyzing student responses to an open-ended questionnaire, I was able to uncover the motivations students had for joining their respective student organizations and what benefits they reported receiving from their participation. I found three major overarching themes for what motivated students to join their respective student organization: they liked the content the organization was based on, to have some form of social outlet, or the reputation of the organization drew them into the organization. Students reported a wide range of benefits they received from their participation in these organizations. I grouped these benefits into five overarching themes: Networking, Professional Development, Learning Opportunities, Community Involvement, and Prestige. I found that there was some overlap between students’ motivations for joining their student organization and what benefit they received from their participation. With this overlap, I speculate that a feedback loop exists where students join an organization for a specific reason that guides what events they choose to participate in which then leads into the benefit they receive from their participation. Now that we better understand how these organizations function, what motivates students to join content-based student organizations, and what they are getting from their experiences, we can further promote these groups to new students. By joining a content-based student organization, students will be better able to find their place in science through networking with others in their field and honing and developing skills that they can take into the workforce, ultimately making them more competitive on the job market.

▼ Apoptosis is the process of programmed cell death characterized by morphological and physiological changes executed by cells in response to a stimulus. The apoptotic process contributes to the loss of milk secreting cells (i.e. mammary epithelial cells) that occurs in the bovine mammary gland once peak lactation has occurred. However, the specific mechanisms by which this occurs are unknown. The goal of this work was to examine the role of the Bcl-2 family of proteins in regulating apoptosis in the bovine mammary epithelial cell line, MAC-T. The Bcl-2 family is divided into three categories based on protein function and combinations of four Bcl-2 homology (BH) domains. Anti-apoptotic multidomain proteins, such as Bcl-2 and Mcl-1, prevent apoptosis by binding to pro-apoptotic members of the family. Pro-apoptotic multidomain proteins, such as Bax, help to regulate apoptosis at the mitochondrial outer membrane. Pro-apoptotic BH3-only proteins, such as Bad and Bim, act as messengers between the anti-apoptotic and pro-apoptotic proteins. To investigate the roles of Bcl-2 proteins in apoptosis, MAC-T cells were treated with anisomycin (ANS), an activator of the intrinsic apoptotic pathway. ANS had little effect on Bcl-2 or Bax mRNA levels while it induced a 40 to 60% decrease in levels of Bad mRNA. Protein expression of Bax did not change during apoptosis, while Bcl-2, Mcl-1, and Bad expression decreased to varying degrees. The greatest change in protein levels was observed for Mcl-1, whose expression was nearly non-detectable after 4 h of treatment with ANS. Bim was phosphorylated in response to ANS but this was not caused by JNK or p38 signaling. Knock-down of Bim using siRNA decreased the ability of ANS to induce apoptosis. Mcl-1 and Bim protein expression changed in a similar time frame, therefore, interactions between the two proteins were evaluated using co-immunoprecipitation experiments. Mcl-1 and Bim interacted both basally and after treatment with ANS. The significance of Bim phosphorylation, the kinase responsible for its phosphorylation, and the functional significance of the interaction between Bim and Mcl-1 in stress-induced apoptosis remain to be determined.

▼ Therapeutic antibodies dominate the pharmaceutical market and improve the lives of millions of people annually. One important step when developing new medicines is to kinetically characterise the drug candidates. For antibodies this is difficult since many antibody reactions are extremely slow. By combining a mathematical formula that was recently published with the well-established technology from Gyros Protein Technologies, a new method for full kinetic characterization was developed and tested in this master thesis. The method provided precise data for five antibodies while also proving to be highly reproducible. By using small sample volumes, unlabelled reagents and having the reaction proceed in solution, this method offers advantages compared to many conventional approaches.

▼ The literature part of this thesis reviewed the process of obtaining affinity information with quartz crystal microbalance (QCM) and surface plasmon resonance (SPR) biosensors. Basic principles of these biosensors were also evaluated, along with the principles of data acquisition and finally the data processing. The raw data produced by QCM or SPR can be used to study biomolecular interactions qualitatively and quantitatively. These techniques are also powerful in obtaining kinetic and thermodynamic information of the biomolecular interactions. SPR and QCM can produce data easily, but data interpretation can be sometimes problematic. This is partly due to misconceptions on how the sensograms should be interpreted. Many of the interpretational problems can and should be avoided long before the modeling of the data takes place to obtain reliable affinity data.
The literature part of this thesis also presents tools for developing good experimental design. Well-designed experimental set-up is the most important element for producing good biosensor data. One should also estimate from the sensogram shapes what kind of analysis is needed. This was explained in detail in the literature part, pointing out the key elements how sensograms with certain shape should be interpreted and further analyzed to obtain affinity constants. Data analysis part of the literature review provides also information how to use appropriate models (e.g. fitting equilibrium, kinetic or complex data) with extensive examples. Surface site distribution model will be also covered as the tool to analyze complex biomolecular interactions by QCM and SPR.
In the experimental part, affinity of anti-human apoB-100 monoclonal antibody (anti-apoB-100 Mab) towards different lipoproteins was studied with partially filling affinity capillary (PF-ACE) electrophoresis and QCM. PF-ACE with adsorption energy distribution (AED) calculations provided information on the heterogeneity of the interactions. For the first time, a modified surface site distribution model called Interaction map was utilized to model QCM data of lipoprotein interactions with anti-apoB-100 Mab. With the Interaction maps, it was possible to distinguish different kinetics of low-density lipoprotein (LDL) and anti-apoB-100 Mab interactions. Affinity constants obtained were used to evaluate thermodynamics of these interactions. Both methods were also used to evaluate interactions with other apoB-100 containing lipoproteins: intermediate-density lipoprotein (IDL) and very lowdensity lipoprotein (VLDL). It was found that the Interaction maps could distinguish two different kinetics from the mixture of IDL-VLDL with distinct affinity constants. Both methods agreed well with the affinity constants. It was found that the anti-apoB-100 Mab used in this study, had a high affinity towards apoB-100 containing lipoproteins.
In the second part of the experimental, a convective interaction media (CIM) based LDL isolation platform was developed. In these studies, anti-apoB-100 Mab was immobilized on the…

▼ ENGLISH ABSTRACT: Advances in pharmacology, biochemistry and biotechnology are increasingly dependant upon
affinity chromatography as a preferred separation technique for the purification and
characterisation of specific biomolecules.
In the past few years avidin-biotin technology has been widely and successfully used in the fields
of medicine, pharmacy, biology and biochemistry. The avidin-biotin complex (ABC) has been
used as a mediator for
affinity chromatography,
affinity cytochemistry, immunoassay,
histopathology, bioaffinity sensors, erosslinking and immobilisation studies.
The main reason for the popularity of the ABC and its growing usefulness in biotechnology is the
exceptionally high
affinity (1015 M-l) and stability of the noncovalent interaction between avidin
and biotin. The use of the ABC is broadening as different biotin derivatives and
avidin-containing conjugates are becoming commercially available.
The aim of this work was to evaluate the usefulness of a plutonic" FI 08 and the ABC conjugate
to effect
affinity separation. Towards this aim, the adsorption of plutonic" F108 onto
hydrophobic polysulphone membrane surfaces was studied. This information was used to
determine the theoretical maximum amount of pluronic" FI08 that will adsorb onto a unit
surface area of the membrane. It is known that the polypropylene oxide (PPO) centre block ofthe
pluronic" F I08 surfactant molecule governs the concentration of pluronic" F I 08 molecules that
will adsorb onto a given hydrophobic surface. If the maximum coating concentration of
plutonic" FI08 is known, one can assume that the maximum coating concentration of any
pluronic derivative, with the same PPO centre block size, will be the same. Adsorption studies
were carried out, the Langmuir adsorption isotherm was determined, and subsequently the
fractional coating was calculated.
The end-groups of plutonic" FI08 were modified as follows and the substituted pluronic was
adsorbed onto a membrane that was to act as the solid support matrix in the development of an
affinity system: Amino pluronic was synthesised by first tosylating pluronic" FI08, followed by azidation with NaN3 then reduction with LiAI~. The synthesised amino pluronic was then
biotinylated using N-hydroxysuccinimide biotin ester. The suitability of this synthetic route was
first assessed on a model compound, 2-methoxyethylamine, and validated by NMR (Nuclear
Magnetic Resonance) spectroscopy. The synthetic protocol was then used to derivatise the larger
pluronic molecule.
The
affinity system was tested on two different hydrophobic surfaces: polystyrene and
polysulphone membranes (PSMs). Avidin-conjugated horseradish peroxidase was obtained and
used to interact with the immobilised biotin. The enzymatic reaction of the coupled peroxidase
converted the substrate, 2, 2'-azino-di-(3-ethyl-benzthiazoline-6-sulphonic acid) (ABTS) to a
coloured product. The colour developed is proportional to the amount of biotin that was
immobilised on the hydrophobic surfaces studied.

▼ To induce the production of antibodies, exogenous antigens are taken up and degraded in antigen presenting cells in vivo. Since this process inevitably lead to distort antigenâs structure, it is likely that some arising antibodies following immunization may not react appropriately with native protein. In the present study, comparative studies on the reactivity of cobrotoxin and recombinant cobrotoxin toward anti-cobrotoxin antibodies were carried out. CD spectra and acrylamide quenching of Trp fluorescence showed that global structure of recombinant cobrotoxin was different from that of native toxin. Results of ELISA and dot blotting assay revealed that recombinant cobrotoxin had a superior reactivity toward anti-cobrotoxin antibodies than native toxin did. Reactivity with antibody fractions specifically against N-terminal region or C-terminal region of cobrotoxin also showed the same results. The binding of recombinant cobrotoxin with antibodies was stronger than that of cobrotoxin as revealed by ammonium thiocyanate elution assay. Recombinant protein was susceptible to reduce its antigenicity after tryptic digestion compared to cobrotoxin. Distorting disulfide linkages at C-terminus caused a marked decrease in immunoreactivity of recombinant cobrotoxin, indicating that anti-cobrotoxin antibodies mostly recognized conformation-dependent epitopes. Moreover, cobrotoxin and recombinant cobrotoxin showed a similar immunoreactivity under denaturing condition. Taken together, these results suggest that native conformation with cobrotoxin may unfavorably impede the interaction of some epitope(s) with anti-cobrotoxin antibodies.

▼ The formation of base pair radical anions and cations is closely related to many fascinating research fields in biology and chemistry such as genetic mutation, radiation-induced DNA damage and dynamics of charge transfer in DNA. However, the relevant knowledge so far mainly comes from studies on isolated base pair radical anions and cations, and their behavior in the DNA environment is less understood. In this study, we focus on how the nucleobase sequence affects the properties of the guanineâcytosine (G:C) base pair radical anion and cation. The energetic barrier and reaction energy for the proton transfer along the N1(G)âHâ¢â¢â¢N3(C) hydrogen bond and the stability of (G:C)⢠(i.e., electron
affinity and ionization potential of G:C) embedded in different sequences of base-pair trimer were evaluated using density functional theory and two-layer ONIOM method. The computational results demonstrated that the presence of neighboring base pairs has an important influence on the behavior of (G:C)⢠in the gas phase. The excess electron and positive hole were found to be localized on the embedded G:C and the charge leakage to neighboring base pairs was very minor in all of the investigated sequences. Accordingly, the sequence behavior of the proton transfer reaction and the stability of (G:C)⢠is chiefly governed by electrostatic interactions with adjacent base pairs. However, the effect of base stacking, due to its electrostatic nature, is severely screened upon hydration, and thus, the sequence dependence of the properties of (G:C)⢠in aqueous environment becomes relatively weak and less than that observed in the gas phase. The effect of geometry relaxation associated with neighboring base pairs as well as the possibility of proton transfer along the N2(G)âHâ¢â¢â¢O2(C) channel have also been investigated. The implications of the present findings to the electron transport and radiation damage of DNA are discussed.

▼ Companies compete for employees based on their
perceived employer brand value. This study investigates what
influences a strong or weak employer brand has on the preference
for total rewards. The results should assist remuneration agents in
appropriately leveraging the company’s employer brand value, as a
factor, when compiling a total rewards package for potential
employees. A questionnaire was developed, asking participants to
indicate their preferences relating to total rewards in the context
of their current employer, with regard to stronger and weaker
employer brands. Results of the study indicate that potential
employees would require financial reward increases in the range of
15% - 30% in order to change employment, irrespective of whether it
is perceived as a strong or weak employer brand. It was observed
that a stronger employer brand could offer increases closer to the
bottom of the range compared to weaker employer brands which would
have to pay a premium to the top end of the range Employer brand
value appears to increase the total reward costs for companies,
irrespective of how the brand is perceived. It is however
beneficial to be viewed as a strong employer brand, as the value of
this perception translates to a smaller premium compared to weaker
employer brands.
