Prerequisites for admission
Based on the knowledge acquired in the "Biology and Genetics" and "Chemistry and Biochemistry" courses, students are expected to possess knowledge of the principles of cellular and subcellular organization, of the structure and function of biological macromolecules, of the molecular biology of the cell, of genetics, enzymology, bioenergetics and metabolic circuitries.
The course comprises 12 CFU.
Of these, 9 are provided during the second semester of the second year of the master degree course. At the end of this phase, the students are admitted to the exam.
This part of the course is further subdivided in 8 CFU of "frontal" teaching (see the detailed program below) and 1 CFU of laboratory activity ("Attività Professionalizzanti"). Frontal teaching is based on the use of slides in Power Point. The slides are uploaded onto the Ariel website. For these latter activities, students are grouped into groups of 3 students, each assigned to a tutor, and spend three consecutive afternoons in the lab, participating "hands-on" on a mini-project in genomic medicine. These activities are designed to familiarize the students with the basic and translational research activities behind the concepts and the progresses in genomic and precision medicine.
Three CFUs are provided during the 5th year as a part of the integrated Clinical Medicine course (D53-153). These CFUs take up topics related to the pathological bases of diseases that represent an integral part of the General Pathology and Fisio-Pathology course of the 2nd year and, as such, are not object of additional examination. As a whole, these 3 CFUs represent a "Back to Basics" section that aims at highlighting the importance of discussing the different aspects and multifaceted implications of basic science for clinical medicine, in the perspective of a better patient care. The goal is to familiarize the students with cutting edge genomic and molecular knowledge and demonstrate, through the discussion of specific clinical cases and disease models, the relevance of basic research findings to the clinico-prognostic and therapeutic improvements in the clinical practice.
In addition to frontal teaching, the course also takes the form of teacher-guided lectures and seminars delivered by groups of 2/3 students, which represents an effective strategy to encourage active learning and communication, and develop critical-thinking and decision-making in relation to clinical problems.

Assessment methods and Criteria
The exam consists in a single oral examination. There are no intermediate tests.
The oral examination aims at evaluating the ability of the student to express him/herself with clarity, scientific rigor, and appropriate language on the topics of the course: a) molecular mechanisms of damage at the cellular, tissue and organismic level, b) subcellular, cellular, tissue and organismic responses to damage, c) integration of the said elements towards the understanding of selected topics in physiopathology, d) state-of-the-art in genomic medicine and precision medicine.
The oral exam last, on the average, 30-40 minutes and consists of the discussion of 3-4 general topics, selected among the general issues of cellular and tissue damage and organismal responses, acute and chronic inflammation, oncology, genomic medicine, and physiopathology. Within the discussion of each topics, there is further "ad hoc" deepening into single aspects of the problems.
The outcome of the exam is expressed in thirtieths.
