Am J Physiol Heart Circ Physiol 285: H1378–H1384, 2003; 10.1152/ajpheart.00137.2003.—Rapid atrial pacing causes electrical remodeling that leads to atrial fibrillation (AF). AF can further remodel atrial electrophysiolog...

Abstract Background Fluoride may induce oxidative stress and apoptosis. It also lead to neurobehavioural defects including neuromuscular damage. The present study aimed explore the effects of sub lethal concentrations sodium fluoride (NaF) on lifespan climbing ability Drosophila melanogaster. In total, 0.6 mg/L 0.8 NaF were selected as sublethal for study. Lifespan was measured activity assay p...

BACKGROUND Sodium fluoride is the preferred agent to inhibit glycolysis. Its action is not immediate, however, and complete inhibition is delayed for up to 4 hours. A more effective method is needed. Acidification of blood combined with the addition of NaF and EDTA appears to be such a method. We studied whether acidification was indeed more effective than NaF. METHODS We conducted 6 independ...

The importance of fluoride as a natural and industrial toxicant is recognized worldwide. We evaluated the regulating role and biological effect of vesicular (liposomal and nanoencapsulated) melatonin (N-acetyl-5-methoxytryptamine) for drug delivery and controlled release on the depletion of inflammatory mediators, as well as oxidative damage in sodium fluoride (NaF)-treated lungs and liver. Hep...

Gallic acid has been identified as an antioxidant component of the edible and medicinal plant Peltiphyllum peltatum. The present study examined its potential protective role against sodium fluoride (NaF)-induced oxidative stress in rat erythrocytes. Oxidative stress was induced by NaF administration through drinking water (1030.675 mg m(-3) for one week). Gallic acid at 10 mg kg(-1) and 20 mg k...

Regulation of cell volume is an important aspect of cellular homeostasis during neural activity. This volume regulation is thought to be mediated by activation of specific transporters, aquaporin, and volume regulated anion channels (VRAC). In cultured astrocytes, it was reported that swelling-induced mitogen-activated protein (MAP) kinase activation is required to open VRAC, which are thought ...

The objective of this research was to evaluate the anticaries effectiveness of a low-dose (500 ppm F, low-NaF) sodium fluoride dentifrice, a high-dose (2,800 ppm F, high-NaF) sodium fluoride dentifrice and an experimental 0.454% stabilized stannous fluoride (1,100 ppm F) with sodium hexametaphosphate (SnF2-HMP) dentifrice, each relative to a standard 1,100 ppm F sodium fluoride positive control...

Male Sprague-Dawley rats were fed control diet or diet containing 0.05% nafenopin (NAF) or 0.025% WY-14,643 (WY) and male Syrian hamsters were fed control diet or diet containing 0.25% NAF or 0.025% WY for periods of 1, 15, 40, and 60 weeks. Both NAF and WY produced a sustained increase in liver weight and induction of peroxisomal fatty acid beta-oxidation in the rat and Syrian hamster. Replica...
