Introduction: Sporadic primary hyperparathyroidism (sporadic PHPT) is a common endocrine disorder, usually caused by a single parathyroid adenoma. However, up to 15% of patients present with multiple gland disease (MGD), which cannot be always diagnosed preoperatively, raising serious management problems. No predictive genetic screening tests are currently available to distinguishing adenomas from MGD in sporadic PHPT. MiRNAs are widely established as genetic molecules that ha...

Introduction: Denosumab is a new pharmacotherapy option for postmenopausal osteoporosis. It is a human monoclonal antibody against RANKL, acting as an osteoprotegerin (OPG) analog. Recently, osteoprotegerin levels were found to be elevated in type two diabetes while insulin resistance was shown to be positively associated with decreased serum OPG levels, in healthy obese subjects. However, no study has been conducted in order to clarify the effect of anti-RANKL factors adminis...

Introduction: Papillary thyroid microcarcinomas (PTMC) are usually considered low-risk tumors with favorable prognosis. However, a small percentage behaves aggressively and controversies exist for various prognostic factors. The aim of this study was to evaluate demographic and tumor specific characteristics related to PTMC invasiveness.Patients – methods: This is a retrospective study of 510 thyroidectomized patients with PTMC who were treated in t...

Background: Hypothalamic KNDy neurons have recently been identified as key regulators of reproductive function by releasing three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin. Animal studies show they interact to control pulsatile GnRH release, which is vital for fertility. In animals, kisspeptin stimulates, NKB modulates and the opioid dynorphin inhibits GnRH pulsatility. However, the interaction of these peptides has never been studied in humans. To inve...
