Besides its critical functions as a reproductive hormone, 17β-estradiol (E2), plays an important role in the control of energy homeostasis. In experimental animals, reduction of circulating estrogen levels by bilateral ovariectomy leads to the development of obesity, which can be reversed or prevented by E2 treatment. E2 effects on energy balance resemble many similarities to the actions of leptin, key molecule involved in the control of e...

Although still controversial, these carcinomas appear to have a better prognosis. This study aims to evaluate the presence of thyroiditis in thyroids with PTC and the association with histological variables of prognostic value, Tg and evidence of metastasis in 131I scan.Methods: Descrip...
