Cerebellar and hypothalamic regulation of vestibular compensation after unilateral labyrinthectomy in rat Abstract #790
Introduction: The mechanisms of inhibitory regulation of neuronal activity of the vestibular system in health and in the vestibular compensation (VC) occurred with participation of the cerebellum, while non-cerebellar pathways are essential in restoring the stability of visual orientation during movement.
Aim(s): We investigated manifestations of the post stimulus excitatory and inhibitory activity of the Deiters’ neurons in response to high-frequency stimulation of I-V lobules of the cerebellar cortex. Post stimulus activity appeared in the form of tetanic potentiation and depression, followed by post tetanic potentiation and depression.
Materials and methods: In Deiters’ neurons to HFS of the cerebellar anterior cortex were predominantly revealed TD in intact rats, more pronounced at 100 Hz. On the third day after the unilateral labyrinthectomy, even to stimulation of the cerebellum by 50 Hz observed TD in Deiters’ neurons similar to those in intact rats at 100 Hz, but as a rule twice better expressed and accompanied by PTD and PTP.

#160 The role of T-type calcium channels in medullary thyroid carcinoma (MTC): T-type calcium channel blockers inhibit hormone secretion and induce apoptotic cell death in a human MTC cell line
Introduction: Medullary thyroid carcinoma (MTC) accounts for approximately 5-10% of thyroid cancers. In the case of tumors limited to the thyroid gland, the prognosis is generally favorable, whereas 5-year survival averages only 40% in patients with metastatic disease. In these patients, conventional chemotherapy only occasionally leads to a complete response and partial responses are observed in less than 30% of the cases. Therefore, intense efforts are currently directed toward the identification of new druggable targets for the treatment of this devastating disease.
