Dehydroepiandrosterone (DHEA) and its sulphate ester DHEAS are neurosteroids with potential effects on neurogenesis, neuronal survival and neuronal stem cells proliferation. DHEA is produced by the inner adrenocortical zone, which is in direct contact to the adrenomedullary chromaffin. Unlike the closely related sympathetic neurons, chromaffin cells are able to proliferate throughout the life span. The aim of the present study was to examine in vitro the effect of DHEA ...

Background and aims: The aim of the present study was to evaluate real-time elastography (RTE) and contrast-enhanced ultrasound with Sonovue (CEUS) for the differentiation of benign and malignant thyroid nodules using cytologic/histologic analysis as reference method. While first studies have reported excellent results of RTE for the differentiation of thyroid nodules, data on CEUS of the thyroid are rare.Methods: RTE was classified as: score 1=soft, 2=p...
