Risk markers for acute stroke in Ireland - association of sodium-lithium countertransport (SLC) with vascular disease
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2002)The work in this thesis is divided into two parts, an epidemiological study of the risk markers for stroke in an Irish population and a laboratory study of the possible association between sodium lithium countertransport ... -
β-adrenoceptor-mediated regulation of matrix metalloproteinase-9 in fibroblasts
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2011)Adrenoceptor signalling in fibroblasts: Intracellular cAMP levels were measured by a direct cAMP enzyme immunoassay. Isoprenaline (ISO, 1 μM) increased intracellular cAMP concentration by 1.3 and 4.8 fold, P<0.05, after ... -
Health technology assessment in the Irish healthcare setting : application to oral anticoagulants
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2012)The objective of this thesis was to examine the application of economic evaluation within the Irish healthcare setting. In so doing, the author sought to develop skills in indirect comparison, economic modelling, value of ... -
Genetic polymorphisms and arterial stiffness
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2008)Arterial stiffness exerts a major influence on cardiac afterload and coronary perfusion. Indices of arterial stiffness have therefore been proposed as surrogate markers of cardiovascular risk and as potential therapeutic ... -
Pharmacoepidemiology of diabetes mellitus in a national population
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2010)Diabetes is associated with significant morbidity and mortality from microvascular and macrovascular complications. It is projected that the prevalence of diabetes will increase worldwide especially in the elderly population ... -
The use of the General Medical Services prescription database for pharmacoepidemiological studies in Ireland
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2003)Pharmacoepidemiology may be divided into three main subdivisions, namely pharmacovigilence, drug utilisation and prescribing quality. An aim of this thesis was to demonstrate the usefulness of the General Medical Services ... -
Health economics in the Irish healthcare setting
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2008)Economic analysis plays a key role in deciding which healthcare interventions should be made available in collectively funded healthcare systems. The aim of this thesis is to examine the application of health economics in ... -
Pharmaceutical pricing and reimbursement : an Irish perspective
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2006)There has been a five-fold increase in state expenditure on medicines under the Community Drug Schemes in Ireland over the last decade (1994 to 2004). As a result of this marked increase in pharmaceutical expenditure, the ... -
Nuclear receptor activation by antiretroviral drugs used in the treatment of HIV disease with implications for xenobiotic and endobiotic processes
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2012)Genotyping: DNA was isolated from whole blood of 1013 HIV-patients and genotyped commercially for 37 single nucleotide polymorphisms (SNPs) and one 3-basepair insertion in genes of relevance for drug interactions: NR1I2 ... -
Stress and long-term potentiation
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2001)Stress is a physiological reaction which the body copes with by a variety of mechanisms in order to restore homeostasis. Amongst these is an increase in plasma glucocorticoids, catecholamines and increases in brain ... -
Synaptic plasticity in animal models of stress : serotonergic mechanisms
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2005)The inhibitory effect of acute elevated platform stress exposure on synaptic plasticity in the CA1 region of the hippocampus in vivo was investigated. Such stress exposure was confirmed to inhibit subsequent long term ... -
A cluster randomised trial of educational interventions to promote rational prescribing in primary care
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2008)A randomised controlled trial (RCT) was used to evaluate the effectiveness of individualised GP prescribing feedback delivered as a postal bulletin (PB, n=50 practices) compared to PB plus academic detailing visits (AD, ... -
Structural remodelling of the vascular wall in relation to ageing and arterial stiffening
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2006)Structural remodelling of the vascular wall has been investigated in this study in terms of ageing and the process of vascular stiffening. While common structural adaptations are often presumed for ageing and vascular ... -
Endogenous acetylcholine modulates synaptic plasticity in the hippocampus in vivo
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2002)Long-term potentiation (LTP) provides a model for the synaptic mechanisms underlying learning and memory. Acetylcholine (ACh) is an important excitatory transmitter in the hippocampus, and cholinergic activity is essential ... -
The influence of antiviral therapy and HIV / HCV proteins on matrix metalloproteinase and cytokine production : an in vitro and in vivo study
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2012)The effect of antiviral therapy on MMP/TIMP expression in THP-1 and LX-2 cells and in HIV/HCV co-infected patients: MMP-9 activity was measured by gelatin zymography, MMP-9 mRNA expression by real-time RT PCR, and MMP-9, ... -
Assessment of arterial stiffness using oscillometric arteriography
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2009)The present series of studies examined whether an oscillometric method (Arteriograph), which measures arterial stiffness indices, pulse wave velocity (PWV m/sec), and wave reflection as augmentation index [Alx %], is on ... -
Pharmacologically induced long-term enhancement in the hippocampus in vivo
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2007)The present study investigated the mechanisms underlying a pharmacologically induced long-term enhancement (LTE) of fast excitatory synaptic transmission in the CA1 region of the rat hippocampus in vivo. The role of ... -
Prescribing for institutionalised older people
(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2003)Introduction: In order to investigate aspects of prescribing practice and drug administration in institutionalised older people, the following aims for the study were developed; -- To compare prescribing practices between ... -

(Trinity College (Dublin, Ireland). School of Medicine. Discipline of Pharmacology & Therapeutics, 2006)Hypertension and high cholesterol, especially in the middle-aged and elderly, are fairly common, and pharmacological therapy is often required to control them.
