3D respiratory tissue model been shown to be effective for measuring impact of chemicals A 3-dimensional model of human respiratory tissue has been shown to be an effective system for measuring the impact of chemicals, like those found in cigarette smoke, or other aerosols on the lung. Effective lab-based tests must eliminate the need for animal tests in assessing the toxicological effects of inhaled chemical substances and safety of medications DSE . Traditional lab-based tests make use of cell lines that do not reflect regular lung physiology and structure, and perhaps have reduced, or loss of, key metabolic processes.
Since the variation in regular anatomy is increased in hearts with congenital abnormalities, a precise replica – a three dimensional roadmap – – enables surgeons to strategize before entering the operating space. A 3D model allowed me to plan the surgery in advance, which intended Esther spent less time in surgery and received much less anesthesia – producing the task safer. Three-dimensional printing technology can create an object of any shape by printing layer upon layer, employing plastics or additional materials in place of ink, explained Jon Detterich, MD, a pediatric cardiologist who specializes in non-invasive cardiac imaging.
