Morphological, ultrastructural, and biochemical changes induced by sodium fluoride in the tongue of adult male albino rat and the ameliorative effect of resveratrol.

Little knowledge is available about the effects of fluoride exposure on the tongue. This study evaluated the effects of sodium fluoride (NaF) on the tongue ultrastructure and detected the ameliorative effects of resveratrol. Forty adult albino rats were separated into 4 groups: the control group was given a balanced diet and purified water.

Maternal exposure to the environmental pollutant "BDE-47" impairs the postnatal development of rat cerebellar cortex by modulating neuronal proliferation, synaptogenesis, NGF and BDNF pathways.

Unlabelled: 2,2',4,4'-Tetrabromodiphenyl ether (BDE-47) is an environmental contaminant that crosses the blood placental barrier and interferes with the homeostasis of fetal thyroid hormones.

Aim Of Work: This study was designed to investigate the perinatal effect of BDE-47 exposure on the postnatal development of the rat cerebellar cortex.

Materials And Methods: This study was carried out on 20 pregnant rats and 36 of their offspring.

Effects of titanium dioxide nanoparticles on the myocardium of the adult albino rats and the protective role of β-carotene (histological, immunohistochemical and ultrastructural study).

Titanium dioxide nanoparticles (TiO NPs) are the most produced nanomaterials. TiO NPs are used as a drug carrier and molecular imaging vehicle in the cardiovascular system. We aimed to study TiO NPs effects on the ventricular myocardium and evaluate the ameliorative effects of β-carotene (βC).
