Formulation and characterisation of polyelectrolyte complex nanoparticles for the delivery of salmon calcitonin
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)The studies in this thesis explored the formulation of various polyelectrolyte complex nanoparticles as potential carriers for the delivery of macromolecules. The complexes were formed between a polyanion (hyaluroninc acid, ... -
Formulation, production and biointeraction of micro and nano particulates with potential for use in drug delivery
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2009)The current study involved the preparation of a range of micro and nano particulates from known biocompatible pharmaceutical polymeric excipients: PLGA, chitosan and hyaluronic acid, using physical rather than chemical ... -
The Gut-Brain Axis in Inflammatory Bowel Disease: Assessment of the Central Inflammatory Response to Dextran Sulfate Sodium-Induced Colitis in Rats
(Trinity College Dublin. School of Pharmacy & Pharma. Sciences. Discipline of Pharmacy, 2018)Inflammatory bowel disease (IBD) is a chronic relapsing-remitting inflammatory condition of the gastrointestinal (GI) tract. Evidence indicates a comorbidity between IBD and psychological symptoms in patients. It is thought ... -
Intestinal degradation and absorption kinetics of salmon calcitonin
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2000)The aim of this work was to investigate the intestinal degradation and absorption of a hydrophilic peptide, salmon calcitonin (sCT), and to evaluate the use of bile salt simple and mixed micellar systems as potential ... -
Investigation of cerebral perfusion changes following MDMA Ecstasy administration in an animal model using bolus-tracking arterial spin labelling MRI
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2012)The recreational drug of abuse 3,4 methylenedioxymethamphetamine (MDMA; Ecstasy) carries a risk of cerebrovascular accidents (CVA) that may relate to the role of serotonin (5- HT) and/or dopamine in the regulation of ... -
Investigation of the PSD-95 / nNOS protein interaction as a target for antidepressant activity
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)Previous studies have demonstrated that nitric oxide (NO) synthase inhibitors are as efficacious as tricyclic antidepressants in preclinical antidepressant screening procedures and in attenuating behavioural deficits ... -
Investigation of the solid-state, powder flow and tabletability properties of comminuted active pharmaceutical ingredients
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2013)An understanding of the effect of processing on the solid-state properties of active pharmaceutical ingredients (APIs) is essential for product manufacturing success. During product development it is possible to induce ... -
Investigations of a spray-drying method for producing nanoporous / nano-particulate microparticles (NPMPs) of proteins and protein-excipient composites
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2009)The research, presented in this thesis, concerns the application of a spray-drying method to produce nanoporous/nano-particulate microparticles (NPMPs) of proteins, stabilising excipients and composites. The proposed method, ... -
Investigatons of the potential of crystalline excipients to prevent the process-induced amorphisation of active pharmaceutical ingredients
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2014)The focus of this thesis was to evaluate the impact of mechanical activation (milling and dry mixing) and spray drying on the crystallinity of selected active pharmaceutical ingredients (APIs) and to explore the feasibility ... -
Kinetic and structural studies of novel isosorbide-based ligand binding to esterase enzymes
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2009)The main goal of the project described herein was to examine and rationalise the binding of a novel class of compound based on isosorbide to cholinesterase enzymes. The compounds of interest had been prepared within the ... -
Mechanistic aspects of the degradation and drug release properties of poly-alpha-hydroxyl aliphatic ester nano- and microparticle
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2000)Particulate systems based on the polymers of lactic and glycolic acids have been extensively investigated as drug delivery technologies, particularly as vehicles to achieve controlled release. The release kinetics from ... -
Neuronal Nitric oxide synthase : a novel target for antidepressant activity
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2012)Major depressive disorder (MDD) is one of the most common psychiatric disorders and its origin has been attributed to dysfunction of the monoamine systems, particularly noradrenergic and serotonergic, making them the main ... -
Pharmaceutical services for patients in methadone treatment in Ireland and the introduction of the Methadone Protocol Scheme
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2002)Methadone is a long-acting opiate commonly used in substitution therapy for heroin addiction. In Ireland, prior to 1998, people requiring treatment for opiate addiction could either attend the National Drug Treatment Centre, ... -
Polyamines and polyamine antagonists in cerebral ischaemia
(Trinity College (Dublin, Ireland). School of Pharmacy & Pharmaceutical Sciences, 2005)Polyamines are ubiquitous components of all eukaryotic cells and are found in brain tissue. A number of studies have shown that changes in the levels of polyamines occur following cerebral ischaemia. However, whether ... -
