UNLABELLED In a national prospective registry, we previously studied the impact of (18)F-sodium fluoride PET (NaF PET) on the intended management of cancer patients with osseous metastases. The clinical impact of NaF PET for monitoring the response to systemic therapies in such patients is unknown. The objective of this study was to assess the impact of NaF PET results obtained for treatment mo...
Using intact human platelets, we studied the effect of sodium fluoride (NaF) on platelet aggregation and release reaction and correlated the functional changes to intracellular events specific for either agonist-induced or antagonist-induced platelet responses. At lower concentrations, with a peak activity between 30 and 40 mmol/L, NaF induced aggregation and release of adenosine 5'-triphosphat...
Fluoride is an essential trace element but also an environmental contaminant with major sources of exposure being drinking water, food and pesticides. Previous studies showed that sodium fluoride (NaF) at 5 mM or more is required to induce apoptosis and chromosome aberrations and proposed that DNA damage and apoptosis play an important role in toxicity of excessive fluoride. The aim of this stu...
BACKGROUND Protein carbonyl levels are the most frequently used biomarker of protein oxidation in several human diseases, including cancer. Breast cancer, a worldwide disease with increasing incidence, develops from ductal/lobular epithelium from which nipple aspirate fluid can be collected and analysed to assess tissue metabolic activity. Our aims were to perform an exploratory investigation o...
The objective of this study was to investigate the toxic effects of different concentrations of sodium fluoride (200, 400 and 600 ppm NaF), administered in drinking water for 30 days, on the reproductive system of adult female Sprague-Dawley rats. The rats in the two higher-dosed groups showed clinical signs of toxicity unlike those exposed to NaF at a concentration of 200 ppm. Ingestion of 200...
s 47 Fluoride 36 (1) 2003 control (group 2). Administration of either vitamins C (50 mg/kg body weight/day), D (2 ng/0.2 mL olive oil/animal/day) or a combination of vitamins C+D+E along with NaF caused significant amelioration in body weight and feed consumption, as well as glucose, protein, sodium and potassium concentrations in the serum of Pand F(1)-generation rats compared with the NaF-onl...
In addition to mitochondria, BCL-2 is located at the endoplasmic reticulum (ER) where it is a constituent of several distinct complexes. Here, we identify the BCL-2-interacting protein at the ER, nutrient-deprivation autophagy factor-1 (NAF-1)-a bitopic integral membrane protein whose defective expression underlies the aetiology of the neurodegenerative disorder Wolfram syndrome 2 (WFS2). NAF-1...
Nutrient-deprivation autophagy factor-1 (NAF-1) (synonyms: Cisd2, Eris, Miner1, and Noxp70) is a [2Fe-2S] cluster protein immune-detected both in endoplasmic reticulum (ER) and mitochondrial outer membrane. It was implicated in human pathology (Wolfram Syndrome 2) and in BCL-2 mediated antagonization of Beclin 1-dependent autophagy and depression of ER calcium stores. To gain insights about NAF...
The Evans blue dye (EBD; 961 Da) and the sodium fluorescein dye (NaF; 376 Da) are commonly used inert tracers in blood-brain barrier (BBB) research. They are both highly charged low molecular weight (LMW) tracers with similar lipophobic profiles. Nevertheless, the EBD binds to serum albumin (69,000 Da) to become a high molecular weight (HMW) protein tracer when injected into the circulation, wh...
Synthesis of lanthanide-doped upconversion nanocrystals (LDUNs) with controlled morphology and luminescence has long been desired in order to fulfill various application requirements. In this work, we have investigated the effect of the NaF : Ln(3+) molar ratio, in the range of 1 to 20, on the morphology, crystal structure, and upconversion properties of NaxScF(3+x):Yb/Er nanocrystals that are ...
