Isthmic nodules have similar US and cytopathological features and tumor characteristics to non-isthmic ones

Patients who underwent thyroidectomy were retrospectively reviewed. Group-1 (isthmic) and Group-2 (lober; non-isthmic) were compared. Isthmic nodules appear to be indolent because of having lower malignancy rate. The surgery with limited extent or follow-up might seem to be reliable in the management of patients having isthmic nodules especially with indeterminate cytology. Read More →

β-scoliidine, present in Japanese solitary wasp venom, protects neuronal cells from oxidative stress

Solitary wasp venoms represent a rich source of molecules of pharmacological interest. Thus, to unravel the content of Scolia decorata ventralis venom, proteomic techniques were used, and two new peptides were determined as its major components, α-scoliidine and β-scoliidine. Interestingly, β-scoliidin was effective in protecting neuronal cells against oxidative stress. Read More →
