There is concern that the ingestion of fluoride (F) from topical application of 1.23% APF gel may cause gastric irritation and other side effects. In this in vitro study, a newly developed APF-based foam was tested. Sound human enamel was treated for 4 rain with APF foam or a conventional APF gel (Nupro®), both containing 1.23 % F. Enamel biopsies were obtained using the acid-etch technique. Th...

INTRODUCTION Reliable animal models are required to evaluate novel treatments for osteosarcoma. In this study, the aim was to implement advanced imaging techniques in a murine model of orthotopic osteosarcoma to improve disease modeling and the assessment of primary and metastatic disease. MATERIALS AND METHODS Intra-tibial injection of luciferase-tagged OPGR80 murine osteosarcoma cells was p...

The oxygen, uptake of lightly heparinized human blood was found to increase markedly upon the addition of bacterial endotoxins, soluble antigen-antibody complexes, or polystyrene latex particles. The effect apparently reflects a transitory stimulation of respiratory activity of the blood leucocytes. The effect did not occur in the presence of anticoagulant amounts of citrate or ethylenediaminet...

ABSTRACT: Excess fluoride ion (F) in drinking water causes harmful effects such as dental and skeletal fluorosis. Hence, its concentration in drinking water must not exceed a certain range. This study investigated the removal of F from aqueous solutions with CuO nanoparticles using a range of experimental approaches, including pH, adsorbent dose, contact times, and initial F concentration. The ...

Atmospheric pressure non equilibrium plasma treatments have been implemented to produce solvent-free Poly-L-lactic acid (PLLA) scaffolds, to improve biocompatibility of PLLA mats and to increase electrolyte uptake of Poly(vinylidene fluoride) (PVDF) separators for lithium batteries. It has been observed that plasma treatments are a suitable way to improve polymeric solution electrospinnability,...

statement of the problem generally, the main source of fluoride intake is drinking water. excessive consumption of bottled water as a substitute or in addition to the tap water supply may have implications for safe fluoride supplementation. in this study, fluoride contents in six commercial brands of bottled water were measured materials and methods six different brands of bottled drinking wate...

Atherosclerotic burden has become the focus of cardiovascular risk assessment. PET/computed tomography (CT) imaging with tracers 18F-fluorodeoxyglucose and 18F-sodium fluoride shows arterial wall inflammation microcalcification, respectively. Arterial uptake both is modestly age dependent. consistently associated factors more easily measured in heart. Because extremely high sensitivity, ultrash...

The development of toxicity to the fluoride ion (F) may be complex and multifactorial with a number of pathophysiological pathways being possible, with the potential for interactions between toxins involving additivity, synergism, and antagonism, and with a number of other factors having predisposing and protective effects. In addition to cognitive impairment with a reduced intelligence quotien...
