The composition of this microbial community is host specific, evolving throughout an individual's lifetime and susceptible to both exogenous and endogenous modifications. Recent renewed interest in the structure and function of this “organ” has illuminated its central position in health and disease. The microbiota is intimately involved in numerous aspects of normal host physiology, from nutritional status to behavior and stress response. Additionally, they can be a central or a contributing cause of many diseases, affecting both near and far organ systems. The overall balance in the composition of the gut microbial community, as well as the presence or absence of key species capable of effecting specific responses, is important in ensuring homeostasis or lack thereof at the intestinal mucosa and beyond. The mechanisms through which microbiota exerts its ben...

As well, surgeon movements are amplified and therefore they must be accurate and smooth. Moreover, the surgeon has to deal with the fulcrum effect, and learn how to manipulate instruments in a 3D space based only in 2D images. Therefore, training in laparoscopic surgery requires the stimulation of the visuospatial and motor skills of the surgeon. It should stress the manipulation of laparoscopic surgery instruments and the interpretation of 2D images of human internal organs and tissues. In this paper we present LAPAROS, a new laparoscopic surgery training system that allows the user to learn navigation inside the human body and interactively manipulate laparoscopic surgery instruments. The system is based on virtual reality technology and 3D computer graphics. We have also incorporated our own state-of-the-art mechanical simulator. LAPAROS provides the user with several training exercises displaying different skill levels. The system provides an evaluation tool and also keeps track of all training sessions for every user, so they can have a feedback on their overall improvement at any moment.

Moreover, the size of the instruments and limitations on video imaging reduces the perception of the surgeon during the surgery. Laparoscopic training is usually performed in animals, cadavers or real patients. However, this technique of training presents some problems. LAPAROS is a new laparoscopic surgery training system that allows the surgeon to develop and acquire the skills demanded for this surgical procedure. This system provides the user with virtual exercises based in our own experience at medical school. LAPAROS is based on virtual reality technology and 3D computer graphics. The hardware component is based in our own state-of-the-art mechanical simulator and a tracking subsystem. The system provides a metric evaluation in each exercise and also keeps track of all training sessions for every user.
