Serotonin-Dopamine interaction in Nicotine Addiction: Focus on 5-HT2C Receptors
Central dopaminergic systems play a critical role in the regulation of normal and abnormal behaviors. Recent evidence suggests that a dysfunction of dopamine (DA) and serotonin (5-HT) neurotransmitter systems contribute to various pathological conditions. Substantial evidence indicates that the mesolimbic pathway, particularly the DA cells innervating accumbal areas, is implicated in the reward value of both natural and drug reinforcers, such as sexual behavior or psychostimulants, respectively.

A BRIEF DISSECTION'S GUIDE TO NORMAL MEDIASTINAL ANATOMY
The purpose of this article is to show the mediastinal dissection method used during the stage performed by a group of students from the Univrersity of palermo that, during the sumer of 2017, had the opportunity to spend a period of 4 weeks at the Department of Anatomy of The University of malta. The students were guided to practice dissection of some corpes to study various mediastinal organs.

A BRIEF ANATOMO-SURGICAL DISSECTION GUIDE TO HUMAN NECK: RESULTS OF THE COLLABORATION BETWEEN THE UNIVERSITY OF PALERMO AND THE UNIVERSITY OF MALTA
The aim of this article is to show methods for dissection of the neck. In the summer of 2017 a group of students of the University of Palermo that have already passed the exam of Human Anatomy took a 4 weeks dissection course at the University of Malta. The students were provided with a dissection kit, video recording equipment and cameras for taking pictures. They dissected the skin, the subcutaneous tissue, the muscular bundles, the muscles, the vascular and nervous bundles, the nerves, the larynx, the trachea and the esophagus. This paper presents the results of the dissection course and a small and simple guide to young students and medical doctors who want to learn the bases of neck di…
