Aluminum (Al) can cause neurotoxicity, a low-turnover osteomalacia, and microcytic anemia. To test the null hypothesis that the chemical form (species) of Al does not influence its mechanism or rate of absorption from the gastrointestinal tract, Al flux across and uptake into Caco-2 cells was investigated. Caco-2 cells were grown on porous membranes mounted in vertical diffusion chambers or in ...
Fluoride and arsenic are hazardous inorganic contaminants due to associated health risks relatively higher levels of occurrence in groundwater. Metal-organic frameworks, (MOFs) with their high surface area, versatile building blocks numerous active sites, a novel approach fluoride uptake. This review presents the different types MOFs for removal along study dynamic breakthrough times cost analy...
OBJECTIVE Calcium fluoride deposit during fluoride application. Uptake and retention of fluoride by saliva depends generally on the concentration of calcium. In this study, the effect of calcium pre-rinse on salivary fluoride concentration after a 900 ppm fluoride mouthwash was investigated. MATERIALS AND METHODS This cross-over double-blind randomized clinical trial was conducted in a girls'...

BACKGROUND 18F-Fluoride positron emission tomography (PET) and computed tomography (CT) can measure disease activity and progression in aortic stenosis. Our objectives were to optimize the methodology, analysis, and scan-rescan reproducibility of aortic valve 18F-fluoride PET-CT imaging. METHODS AND RESULTS Fifteen patients with aortic stenosis underwent repeated 18F-fluoride PET-CT. We compa...
PURPOSE 18F-fluoride PET/CT exhibits high sensitivity to delineate and measure the extent of bone metastatic disease in patients with prostate cancer. 18F-fluoride PET/CT could potentially replace traditional bone scintigraphy in clinical routine and trials. However, more studies are needed to assess repeatability and biological uptake variation. The aim of this study was to perform test-retest...
