Is water fluoridation a hidden cause of obesity? Histological study on thyroid follicular cells of albino rats

Introduction: Fluoride in drinking water is known to exert both beneficial and detrimental effects on health. When consumed in excess, it is known to cause adverse effects including dental fluorosis, hip fracture, bone cancer, lower intelligence, and kidney toxicity plus goiter. Aim: This study was carried out to determine the histological changes that might occur on thyroid follicular cells after the administration of sodium fluoride and evaluate their reversibility. Materials and methods:

Effect of sodium fluoride on bone biomechanical and histomorphometric parameters and on insulin signaling and insulin sensitivity in ovariectomized rats

Osteoporosis is a systemic disease characterized by bone degradation and decreased bone mass that promotes increased bone fragility and eventual fracture risk. Studies have investigated the use of sodium fluoride (NaF) for the treatment of osteoporosis. However, fluoride can alter glucose homeostasis. The aim of this study was to evaluate the effects of NaF intake (50 mg/L) from water on the following parameters of ovariectomized (OVX) rats: (1) tyrosine phosphorylation status of insulin recept

Beneficial effects of Emblica officinalis on fluoride-induced toxicity on brain biochemical indexes and learning-memory in rats

AIMS:  The present study was aimed to investigate the effects of Emblica officinalis against fluoride-induced alterations in the behavioral and biochemical abnormalities in rats. DESIGN:  The healthy adult albino rats of Wistar strain (Rattus norvegicus) weighed 200-250 g were used for experiments. The animals were divided into three groups. Group I, control rats received only drinking water (F 0.9 ppm). Group II rats were exposed to fluoride (10 ppm) water for 60 days. Group III rats were

Oxidative stress biomarkers in the freshwater fish, Heteropneustes fossilis (Bloch) exposed to sodium fluoride: antioxidant defense and role of ascorbic acid

The present study highlights fluoride -induced toxicity and the protective role of ascorbic acid in the liver and ovary of freshwater fish, Heteropneustis fossilis. The fish specimens were exposed to different concentrations (35 mg F/L and 70 mg F/L) of fluoride. Parameters related to oxidative stress were studied at the end of the experiment. The biomarkers selected for the study were thiobarbituric acid reactive substances for assessing the extent of lipid peroxidation (LPO) and antioxidant de
