Abstract: <p>Amino acids make up proteins, which are the building blocks of life. A balance of amino acids is needed to maintain a healthy state. Tyrosine (Tyr) is synthesized from the metabolism of phenylalanine, which is an essential amino acid, meaning it can only be obtained from the diet. It is related to many metabolic and neurodegenerative diseases. Tyr can undergo post-translational… more Full Text: USING FLUORESCENT CARBON DOTS FOR BIOSENSING APPLICATIONS OF AMINO ACIDS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master Science in the Faculty of Arts and Science TRENT …

Abstract: <p>The onset of neurodegenerative diseases such as Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS) are typically characterised by the aggregation of protein biomarkers into cytotoxic fibrils. Novel means of analysing these biomarkers are needed to expand the literature toward earlier diagnosis of these conditions. Electrochemical sensors could offer the sensitivity and… more Full Text: ELECTROCHEMICAL BIOSENSORS FOR NEURODEGENERATIVE DISEASE BIOMARKERS: INVESTIGATIONS INTO THE ORIGIN AND DIAGNOSIS OF ALZHEIMER’S DISEASE AND AMYOTROPHIC LATERAL SCLEROSIS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of …

Recently, bio-based phase change materials (PCMs) have received significant attention for thermal energy storage (TES) uses. Vegetable oils are versatile renewable feedstocks that are well suited for the development of sustainable, functional PCMs. PCMs derived from vegetable oil, which… more Full Text: NOVEL ALIPHATIC AMIDES FROM VEGETABLE OILS AS BIO-BASED PHASE CHANGE MATERIALS A dissertation submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of Arts and …

Abstract: <p>The parasitic protist Giardia intestinalis does not synthesize heme and lacks many common eukaryotic heme proteins, yet it expresses four cytochrome b5 (gCYTB5) isotypes of unknown function. These have low reduction potentials and distinct subcellular locations that are consistent with structural features and biological functions that differ from their mammalian counterparts. Isotype III… more Full Text: Expression optimization and NMR spectroscopy of Giardia intestinalis cytochrome b5 isotype III A thesis submitted to the Committee on Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in the Faculty of Arts …

Abstract: <p>The parasitic protist Giardia intestinalis possesses flavohemoglobin (gFlHb), an enzyme that detoxifies nitric oxide to the less harmful nitrate, and is a potential target for antigiardial drugs that act as ligands to the iron of its heme cofactor. In this work, the binding constants KD of gFlHb, three active-site variants (Q54L, L58A, Y30F) and the E. coli flavohemoglobin (Hmp) towards… more Full Text: Ligand Binding Properties of Giardia Flavohemoglobin A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in the Faculty of Arts and Science Trent University Peterborough, …

Abstract: <p>Microfibres, which are threadlike particles < 5 mm, are the most common type of microplastic reported in the environment. However, few studies have focused on their abundance in background natural environments. This study assessed the abundance of microfibres in rainfall samples (from four precipitation monitoring stations) and across three headwater lake catchments that were in… more Full Text: Anthropogenic microfibres in background natural environments in Ireland A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfilment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science Trent …

Abstract: <p>Chemical presumptive tests are used as the primary detection method for latent bloodstain evidence. This work focuses on developing a forensic blood substitute which mimics whole blood reactivity to a luminol solution commonly used in presumptive testing. Designing safe and accessible materials that mimic relevant properties of blood is a recognized research need in forensic science.… more Full Text: Research and development of synthetic materials for presumptive testing in bloodstain pattern analysis: a luminol-reactive forensic blood substitute A thesis submitted to the committee of Graduate Studies in partial fulfillment of the requirements for the …

The present work shows that high molecular weight of TPEUs with enhanced performance can be obtained from lipid-derived monomers… more Full Text: Lipid-derived Thermoplastic Poly(ester urethane)s: Effect of Structure on Physical Properties A Dissertation Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of …
