Introduction: Pituitary Neuroendocrine Tumor (PitNET) subtypes present functioning and silent variants but the silencing mechanisms are still unknown. One of the possible hypotheses could be a decrease in the expression of the specific adenohypophyseal hormone genes. The aim of the present study was to analyze the expression of adenohypophyseal hormone genes in a series of PitNETs, in order to evaluate differences between functioning and silent PitNET subtypes, taking into acc...

Thyroid Doppler ultrasound (TDUS) is highly used in the evaluation of thyroid nodules (TN). Malignant thyroid pathology has been more frequently associated with central vascularization of such nodules. There is controversy regarding the usefulness of the Resistance Index (RI) in the assessment of TN.Our aim was to analyze the utility of vascularization characteristics and RI at TDUS in the distinction of benign and malignant TN.Mat...
