Quantitative Characterization Of Non-Bonded Interactions In Proteins Affecting Human Health And Disease, Maher Mansur

Dissertations

Non-bonded interactions are fundamental forces that govern molecular relationships between two or more molecules. These interactions contribute to the stability of complex biological structures like DNA, RNA, and proteins, and control various biological processes. Almost all of these processes are significantly influenced by protein-protein and protein-ligand intermolecular interactions. Here, the interactions of various proteins with other proteins, peptides, and/or ligands were quantified computationally to tackle human health-related problems. For estimating the intermolecular interactions, a number of computational approaches including protein structure modeling, molecular dynamics simulations, molecular docking, ensemble docking, semi-empirical methods, etc., were used.

With the rise of population placing strain on food supplies and the failure of current prevention strategies to mitigate effects of agricultural pollution, research is needed to develop new technologies for the removal and recovery of nutrients from agricultural runoff and drainage. Geopolymer, an alkali-silicate material polymerized within an acidic or alkaline medium, is promising as an adsorptive substrate due to its multifaceted customizability, cost effectiveness, and adsorptive properties. Hence, the objective of this research was to develop porous metakaolin (MK) geopolymer based adsorptive materials with high affinities for phosphate and ammonium/ammonia to act as nutrient control within agricultural runoff …

Icvd Polymer Thin Film Bio-Interface-Performance For Fibroblasts, Cancer-Cells, And Viruses Connected To Their Functional Groups And In Silico Studies, Asmaa Taha

Nanotechnology Research Centre

Thin polymer coatings are used to improve the interface between biological species and functional materials. Their interaction is significantly influenced by the functional groups and roughness of the polymer film and prediction of the interaction is thus of great interest. However, for conventional polymer films, this cannot be examined independently because of the interplay of defects, residual solvent molecules, roughness, and functional groups. Solvent-free polymer films prepared by initiated chemical vapor deposition (iCVD) exhibit conformal, defect-free characteristics and enable precise tailoring of the functional groups. This facilitates to isolate the contribution of functional groups on the bio-interface performance. Consequently, in …

A Half-Century Of Pacific Salmon Saving Efforts: A Primer On Law, Policy, And Biology, Michael C. Blumm, Daniel J. Rohlf, Adam Eno

Natural Resources Journal

Pacific salmon, the signature species of the Pacific Northwest, have declined across their range for well over a century, due to a myriad of human-caused effects on their habitat and the fish themselves. Restoration efforts—some successful, some halting—began in earnest in the late 20th century, with considerable attention focused on the Columbia Basin, where historically salmon runs were crippled by a large interconnected hydroelectric system of federal and non-federal dams. In the 1980 Northwest Power Act, Congress created an interstate agency, the Northwest Power and Conservation Council, with access to a substantial amount of ratepayer dollars; the agency has chosen …

Epigenetic Regulation Of Cancer Testis Antigens In Hepatocellular Carcinoma, Rinrada Klankajorn

Chulalongkorn University Theses and Dissertations (Chula ETD)

Hepatocellular carcinoma (HCC) represents one of the most common causes of cancer-related death worldwide, with few available treatment options. Cancer-testis antigens (CTAs), notably from the MAGE gene family, have opened new possibilities for improving immunotherapy in HCC due to their tumor-specific expression and high immunogenicity. However, the mechanisms regulating MAGE gene expression are largely unknown. This study explored mechanisms controlling the expression of MAGE-A3 and MAGE-C2. We utilized HCC organoid cultures derived from patient HCC tissues known to represent cancer epigenetic status more accurately than cell lines to study the MAGE gene family expression patterns and promoter methylation patterns. Our …

Development Of Granule Product Containing Curcuminoid Extract And Hyaluronic Acid Derivative For Oral Administration, Natkhanang Boonpetcharat

Chulalongkorn University Theses and Dissertations (Chula ETD)

Curcumin is widely recognized for its various pharmacological properties, including antioxidant, anti-inflammatory, and anti-tumor activities. Nevertheless, the development of curcumin as a therapeutic agent is impeded by its limited oral bioavailability, which stems from its chemical instability, poor aqueous solubility, and rapid degradation. This study aimed to develop granule formulations incorporating hyaluronic acid graft poly(N-isopropylacrylamide) or HA-g-pNIPAM to enhance dissolution and protect curcumin from degradation. Three formulations were developed: F10 (HA-g-pNIPAM physically mixed with curcumin), F10 Encap (curcumin encapsulated within HA-g-pNIPAM), and F11 (curcumin granules without HA-g-pNIPAM). The stability results showed that F10 Encap effectively maintained curcumin content throughout the …

Immune Signaling And Pathogenesis Of Enterocytozoon Hepatopenaei Infection In Pacific White Shrimp Litopenaeus Vannamei, Nutthapon Sangklai

Chulalongkorn University Theses and Dissertations (Chula ETD)

Enterocytozoon hepatopenaei (EHP) is an intracellular microsporidian parasite causing hepatopancreatic microsporidiosis (HPM), a disease that impairs the digestion and nutrients absorption of shrimp and leads to growth retardation and size variation. Our studies aim to comprehensively investigate the host’s immune responses to the EHP infection and the pathogenesis of the parasite. It was found that genes in Toll and JAK/STAT pathways, as well as antimicrobial peptides, were highly upregulated upon the EHP infection. Importantly, suppression of the JAK/STAT pathways resulted in a significant reduction of the c-type lysozyme (LvLyz-c) expression and the elevation of EHP copy numbers. These indicate a …

(2024) Different Maps, Same Territory: Dialogical Self Theory And Its Predecessors, David Kennedy

Collected Papers of David Kennedy

Dialogical Self Theory has not emerged in a historical vacuum. Its fore-runners, whether the Eastern Atman, the tripartite Platonic self with itsclear hierarchical relations, the Cartesian “ghost in the machine,” theFreudian ego-id hydraulic model or the Jungian topography of ego andunconscious, represent the theoretical grounding from which the dia-logical self has emerged and self-articulated as much as have WilliamJames, George Herbert Mead and Mikel Bakhtin. Most of them, includ-ing DST, center on developmental models, and see the self as intrinsi-cally oriented toward a more integrated sense of itself that Jung called“wholeness,” although their internal politics differ. Plato is an authoritar-ian, …

“With Intent To Destroy, In Whole Or In Part”: Genocide, Ethnic Cleansing, And A Lost History, Alexander K.A. Greenawalt

Elisabeth Haub School of Law Faculty Publications

Drawing upon original research into the travaux préparatoires of the 1948 Genocide Convention, this Article advances several claims that complicate the standard account according to which genocide must entail a purpose to physically destroy at least a substantial part of a protected group. The core of the Article closely explores the words “intent,” “destroy,” and “in part,” showing how international authorities have settled on a received and largely uninterrogated wisdom regarding the meaning of these terms, one which is supported neither by the drafting history of the Genocide Convention, nor even by the actual results of the judicial decisions that …

Conceptualizing Language Ideologies About Education: Exploring Perceptions Of Multilingualism Among Marathi Speakers From India, Priya M. Dabak, Jessica Sujata Chandras

UNF Faculty Research and Scholarship

Perceptions of multilingualism have an impact on the educational choices of urban Indians and larger policy decisions around language in education in the Indian state of Maharashtra. By surveying 150 speakers of Marathi, the official language of the state and mother tongue, or first language of survey respondents, perceptions of multilingualism reveal conceptual assumptions and biases that can be uncovered through cognitive-linguistic analysis. Unprompted, survey respondents drew connections between multilingualism and education, underscoring language ideologies, or beliefs about languages which motivate urban Maharashtrians' educational decisions. Education is the stage upon which multilingual speakers in India express their aspirations and anxieties …

Calcium Permeability Of Rat Trpv1 In A Close State When Expressed In Xenopus Laevis Oocytes, Zinnia Adhikary

Theses and Dissertations

Transient Receptor Potential V1 (TRPV1) is a nonselective cation channel, which is expressed in nociceptors/ pain detecting receptors. Activated by a wide variety of exogenous and endogenous physical and chemical stimuli such as heat, TRPV1 is involved in temperature detection, body temperature regulation, and pain perception. It is generally accepted that TRPV1's conductance to cations, including Ca2+, depends on its conformational change from a closed to an open state following gating. In the current study, I observed that the plasma membrane of Xenopus laevis oocytes, upon exogenous expression of rat TRPV1, exhibited weak permeability to Ca2+, as evidenced by the …

Searching For Novel Mutations That Regulates The Mouse Polycystin-2 (Trpp2) Ion Channel, Akhilraj Rajan Pillai

Theses and Dissertations

Polycystin-2 (PC2) is an ion channel belonging to the polycystin subfamily of the transient receptor potential (TRP) cation channel superfamily. Mutations in PC2 are associated with autosomal dominant polycystic kidney disease (ADPKD), one of the most common genetic diseases in humans. Despite extensive studies over the past decades, the role of PC2 in normal and ADPKD kidneys remains largely unknown, and the activation and regulation of this ion channel are elusive. To gain a better understanding of the structure and function of the mouse PC2 channel, this study focused on generating five pore mutations in a gain-of-function (GOF) mutant of …
