In this study, we demonstrate that challenge of endothelial cells (EC) with NaF, a recognized G protein activator and protein phosphatase inhibitor, leads to a significant Erk activation, with increased phosphorylation of the well-known Erk substrate caldesmon. Inhibition of the Erk MAPK, MEK, by U0126 produces a marked decrease in NaF-induced caldesmon phosphorylation. NaF transiently increase...

Sodium fluoride (NaF) is used for prevention of caries in the form of fluoridated drinking water, fluoride tablets etc. In the present study, the effect of NaF-induced alterations in hydroxyproline (Hyp) and collagen was investigated in rat liver. The effect of pretreatment with MgCl2 on NaF-induced changes in liver Hyp and collagen was also studied. The NaF treatment at 5, 10 and 20 mg/kg body...

Objective: This study aims to estimate and compare the time-course change in blood glucose levels by blood cells in serum, and plasma with or without preservatives, which may reflect the rate of glucose utilization by blood cells. Method: This laboratory-based cross-sectional study was carried out using a blood specimen of 28 participants among which 14 were diagnosed with diabetes and 14 were...

This paper reviews the clinical and experimental findings on the effects of sodium fluoride (NaF) on human and animal bone. NaF has been shown to cause a significant increase in axial skeletal bone mass. However, there is concern that the new bone may not provide the desired increase in bone strength. Yet, NaF remains the most commonly used agent capable of stimulating bone formation in most pa...

NAF-1 is an important [2Fe-2S] NEET protein associated with human health and disease. A mis-splicing mutation in NAF-1 results in Wolfram Syndrome type 2, a lethal childhood disease. Upregulation of NAF-1 is found in epithelial breast cancer cells, and suppression of NAF-1 expression by knockdown significantly suppresses tumor growth. Key to NAF-1 function is the NEET fold with its [2Fe-2S] clu...

Introduction: Curcumin, a yellow-pigment, found in the popular Indian spice turmeric (Curcuma longa), poses pharmaceutical applications due to its anti-inflammatory, antioxidant, and chemoprotective properties. Excessive fluoride causes fluorosis leading to neurodegeneration and associated behavioral deficits, particularly in children. This study aimed at investigating the neuroprotective abili...

OBJECTIVE This in vitro study assessed the anti-erosive effect of experimental mouthrinses containing TiF4 and NaF on dentin erosive loss. MATERIAL AND METHODS Bovine dentin specimens were randomly allocated into the groups (n=15): (1) SnCl2/NaF/AmF (Erosion Protection/GABA, pH 4.5, positive control); (2) experimental solution with 0.0815% TiF4(pH 2.5); (3) 0.105% NaF (pH 4.5); 4) 0.042% NaF+...

Previous studies have shown that progesterone concentrations in serum and nipple aspirate fluid (NAF) are significantly correlated in premenopausal women, but estradiol concentrations are not. We therefore sought to ascertain the patterns of both steroids in NAF throughout the menstrual cycle and in postmenopausal women. Simultaneous samples of blood and NAF were obtained from 40 premenopausal ...

The aim of this study was to compare the effect of toothpastes containing TiF(4), NaF, and SnF(2) on tooth erosion-abrasion. Bovine enamel and dentin specimens were distributed into 10 groups (n = 12): experimental placebo toothpaste (no F); NaF (1450 ppm F); TiF(4) (1450 ppm F); SnF(2) (1450 ppm F); SnF(2) (1100 ppm F) + NaF (350 ppm F); TiF(4) (1100 ppm F) + NaF (350 ppm F); commercial toothp...

BACKGROUND Antihyperglycemic drugs have been linked to new-onset atrial fibrillation (NAF). However, the effect of the different classes of antihyperglycemic drugs on the development of NAF in elderly patients has not been well studied. In this study, we investigated the association between different classes of antihyperglycemic drugs and NAF in elderly patients. MATERIALS AND METHODS This wa...
