Fluoride uptake by enamel from stannous fluoride and prophylaxis pastes
… paste (containing nine per cent stannous fluoride) prior to topical application of 10 per cent aqueous solution of stannous fluoride would promote a significantly greater enamel fluoride uptake than when the solution was applied alone; and (2) to determine whether rinsing the mouth with …

Imaging of abdominal aortic aneurysm disease activity and implications for endovascular aneurysm repair
… tissue (on computed tomography) and sodium [18F]fluoride positron emission tomography, in different abdominal aortic aneurysm disease states to better understand the disease process and to assess its implications in EVAR. METHODS: First, we assessed periaortic adipose tissue attenuation in 70 …

Molecular imaging of calcification and inflammation in aortic valve disease and atherosclerosis
… processes (PET) in vivo. The 18F-sodium fluoride (18F-fluoride) isotope has shown promise in early cardiovascular studies. The purpose of this thesis was to elucidate the mechanisms of cardiovascular 18Ffluoride uptake and define how 18F-fluoride PET/CT might play a role in the assessment …

Novel positron emission tomography applications for imaging cardiovascular disease activity
… activity can now be imaged using 18F-sodium-fluoride positron emission tomography and computed tomography which targets microcalcification (diameter <50 μm), providing different information to established macroscopic calcification (minimum diameter 200 to 500 μm) imaged with computed …

Bioactive capabilities explored in polyurethane microcapsules and the inclusion into dental sealants and cement pastes
… cement and pit and fissure sealant with fluoride by toothbrushing, demonstrate the slow, sustained release of calcium, fluoride and phosphate ions from these materials initially formulated with remineralizing agents, examine the effect of microcapsules on cement adhesion to enamel and …

Novel imaging and blood biomarkers in acute aortic syndrome
… imaging. Here, we investigate 18F-sodium fluoride positron emission tomography and computed tomography (PET/CT) and circulating biomarkers in patients with acute aortic syndrome. METHODS: We performed 18F-sodium fluoride PET/CT in 56 patients with aortic dissection, intramural haematoma or …

Novel molecular imaging of cardiovascular disease in man
… (PET-CT), 18F-fluorodeoxyglucose and 18F-fluoride were utilised as markers of metabolic inflammation and active calcification. Cellular inflammation was assessed using ultrasmall superparamagnetic particles of iron oxide (USPIO) enhanced magnetic resonance imaging (MRI). In a prospective …

Using Mechanical Interventions To Enhance Drug Transport To Bone Tumors
… drugs or tracers were administered to assess uptake before and after mechanical loading using in vivo micro-PET/CT imaging. In the first aim of this project, four pilot studies were performed to develop protocols for a replicable and standardized rat model of breast cancer metastasis. These …

Fabrication of Macadamia Nutshell Powder-AI/Fe Metal Oxide Modified Diatomaceous Earth Composite Beads for Fluoride and Pathogen Removal Groundwater
Contamination of drinking water due to fluoride and pathogens is a severe health hazard problem. Excess of fluoride (>1.5 mg/L) in drinking water leads to dental and skeletal fluorosis whereas the presence of pathogens in water can lead to adverse health effects, including gastrointestinal illness, …
