Methods for designing a computer-aided design/computer-aided manufacturing (CAD/CAM) surgical guide are shown. Cutting planes are separated, united, and thickened to easily visualize the necessary bone transfer. These designs can be three-dimensional printed and checked for accuracy.

We developed a new ex vivo model that applies constant tension to the porcine gastric specimen. This development made it possible to evaluate the performance (the height and duration of the submucosal elevation) of various SIMs accurately. The detailed setup methodology of this new model is explained.

Here we provide a protocol to generate in vitro NMJs from human induced pluripotent stem cells (iPSCs). This method can induce NMJs with mature morphology and function in 1 month in a single well. The resulting NMJs could potentially be used to model related diseases, to study pathological mechanisms or to screen drug compounds for therapy.
