Abstract: A key structure includes a circuit board, a keycap, an elastic member and a metal member. The keycap has a bottom facing the circuit board. The elastic member is disposed between the circuit board and the keycap. The elastic member includes a dome portion, a hollow portion, and a contact pillar. The dome portion touches the bottom of the keycap. The hollow portion is located inside of the dome portion. The contact pillar is located in the hollow portion, and the contact pillar extends from the dome portion to the circuit board. The metal member covers the outside of the contact pillar. The metal member comprises a trigger portion, and the trigger portion is a convex portion extending toward the circuit board.

Abstract: The present disclosure provides a method for isolating and purifying mesenchymal stem cells from hernia sac and a method for tissue repair by using the mesenchymal stem cells from hernia sac. The mesenchymal stem cells isolated and purified by the method of the present disclosure have high yield, high cell division ability, do not need to use enzymes as necessary reagents, and have high potential for application in regenerative medicine or tissue engineering for tissue repair.

Abstract: A keyboard includes a bottom plate and keyswitch devices. Each keyswitch device includes a keycap, a first supporting member, and a second supporting member. The keycap is over the bottom plate. The first and second supporting members are connected between the bottom plate and the keycap and respectively include first and second magnetic attraction portions. The second magnetic attraction portion is configured to attract the first magnetic attraction portion. The first and second magnetic attraction portions respectively have first and second abutting surfaces. When the first abutting surface abuts against the second abutting surface, the keycap is at a highest position relative to the bottom plate. When the keycap moves toward the bottom plate from the highest position, the first abutting surface is at least partially separated from the second abutting surface.

Abstract: The present invention is related to a method for protection of bladder from damage, and prevention of frequent urination using a Canavalia ensiformis supplement.

Abstract: The present invention provides a method of repairing a defect in an abdominal wall of a subject, including the steps of: making a small incision through a skin layer above the defect in the abdominal wall, introducing a surgical device including a deformable body through the incision to reach a preperitoneum underlying the abdominal wall around the defect, using the surgical device to identify a protruded region of the preperitoneum extending towards the abdominal wall around the defect, and flattening the protruded region of the preperitoneum and separating the protruded region of the preperitoneum from the abdominal wall with the deformable body in an expanded condition. The method results in low recurrence of abdominal wall defect, less pain, and a shorter hospital stay after surgery.
