Dr. Macaluso is a surgeon and an endoscopist. He graduated in Palermo (Sicily) and is responsible for Digestive Endoscopy of the Hospital Presidium of Ribera (Agrigento). He also has a qualification of Rescue Diver and has coordinated several underwater kinds of research in the Mediterranean, in the hypoxic basins of the oceanic ditches. Dr. Macaluso compared the methanogenic bacterial flora of the hypoxic marine basins, with the methanogenic bacteria of the intestinal
microbiota and he collaborates with the Department of Biotechnology of the University of Siena, on the study of the probable capacity of colon adenomas, to propagate at a distance, a phenomenon that is probably mediated by the physiological intraluminal hypoxic environment of the colon."
