Although it is beyond doubt that mammary cells accumulate iodide via a Na+-dependent transport mechanism, it is not clear if this is the only pathway for iodide transport in mammary tissue. In view of this, experiments were designed to test for the presence of an anion-exchange pathway which could mediate the transport of iodide into mammary cells; thus, the effect of external iodide on sulfate...
N-n-butyl haloperidol iodide (F2) has been shown to antagonize myocardial ischemia/reperfusion injury by blocking calcium channels. This study explores the biological functions of ERK pathway in cardiomyocytes hypoxia/reoxygenation injury and clarifies the mechanisms by which F2 ameliorates cardiomyocytes hypoxia/reoxygenation injury through the extracellular-calcium-dependent and -independent ...
Background :Control of radioactive emissions from nuclear power plants , particularly radioactive iodine compounds before discharge to the environment is important . Methods : In this study, methyl Iodide vapour adsorbtion capacity was evaluated on the basis of the activated carbon and TEDA (tri ethylene di amine), and HMTA (Hexa methylen tetra amine) impregnated activated carbon bed . Re...
The absence of TSH-stimulated radioiodide uptake in differentiated thyroid cancer is associated with a high recurrence rate and reduced survival. We studied regulation of the sodium/iodide symporter gene in human papillary thyroid cancer cell lines (BHP) and primary human thyroid cells. BHP cells expressed very low levels of sodium/iodide symporter mRNA and did not concentrate iodide, but iodid...
Previous studies have demonstrated that short-term oral iodide administration, in doses ranging from 1500 micrograms to 250 mg/day, has an inhibitory effect on thyroid hormone secretion in normal men. As iodide intake in the USA may be as high as 800 micrograms/d, we investigated the effects of very low dose iodide supplementation on thyroid function. Thirty normal men aged 22-40 years were ran...
In several tissues, transient receptor potential vanilloid 4 (TRPV4) channels are involved in the response to hyposmotic challenge. Here we report TRPV4 protein in porcine lens epithelium and show that TRPV4 activation is an important step in the response of the lens to hyposmotic stress. Hyposmotic solution (200 mosM) elicited ATP release from intact lenses and TRPV4 antagonists HC 067047 and ...
introduction: effective debridement of the root canal system with chemical irrigants prior to obturation is the key to long-term success of endodontic therapy. the purpose of this study is to compare the antibacterial activity of 2.5% sodium hypochlorite (naocl) and 2% iodine potassium iodide (iki) solutions as intracanal disinfectant in infected root canals during one-visit endodontic treatmen...
BACKGROUND Pimecrolimus is a calcineurin inhibitor that inhibits T cell and mast cell activation and effectively treats atopic dermatitis. However, its effects on eosinophils, a cell type implicated in allergic disease pathology, are unknown. Therefore, we examined the effects of pimecrolimus on eosinophil superoxide anion production, degranulation and survival. METHODS Purified eosinophils f...
OBJECTIVE Mitochondrial Ca2+ overload is implicated in hyperglycaemia-induced endothelial cell dysfunction, but the key molecular events responsible remain unclear. We examined the involvement of mitochondrial calcium uniporter, which mediates mitochondrial Ca2+ uptake, in endothelial cell dysfunction resulting from high-glucose treatment. METHODS Human umbilical vein endothelial cells were e...
