Abstract: Apparatus and method of removing a liner attached to an implanted acetabular shell. A surgical site is accessed where the acetabular shell has already been implanted into a patient. A rim plate having a through opening is placed over the acetabular shell. A pilot hole is then drilled into the attached liner through the opening in the placed rim plate. After the drilling, the rim plate is removed to expose the drilled hole. A removal tool is inserted into the drilled pilot hole. The attached liner is then disengaged from the implanted acetabular shell with the inserted removal tool.

Abstract: Embodiments of the present application relate to patterned polymer sheets and processes to prepare the same for sequencing applications. In particular, flexible micro- and nano-patterned polymer sheets are prepared and used as a template surface in sequencing reaction and new polish-free methods of forming isolated hydrogel plugs in nanowells are described.

Abstract: The disclosure provides compositions and methods for the preparation, manufacture and use of an adeno-associated virus (AAV) particle for the vectorized delivery of an antibody molecule that binds to HER2.

Abstract: An example front fork for a bicycle disclosed herein includes a crown having a top side and a bottom side opposite the top side. The front fork includes at least one leg coupled to and extending downward from the bottom side of the crown. The front fork also includes a steerer tube coupled to and extending upward from the top side of the crown. The steerer tube includes first and second markings on an outer surface of the steerer tube. The first marking indicates a distance between the first marking and the top side of the crown to enable a user to cut the steering tube to a desired length. The first marking extends in a circumferential direction on the outer surface. The second marking is used to align a stem or handlebars on the steerer tube. The second marking extends in an axial direction and intersects the first marking.

Abstract: An acetabular shell insertion tool with an anti-rotation feature is provided. The insertion tool attaches to an acetabular shell including a center hole having an internal threading and an anti-rotation recess disposed around the center hole and having a predetermined shape. The insertion tool includes an outer shaft and an inner shaft disposed within the outer shaft. The outer shaft has an anti-rotation projection shaped to be received in the anti-rotation recess of the acetabular shell so as to prevent rotation of the outer shaft relative to the acetabular shell, thereby preventing the insertion tool from disengaging from the shell. The inner shaft has a threaded tip adapted to be threaded into the internal threading of the center hole to lock the insertion tool to the acetabular shell.

Abstract: An acetabular implant for hip arthroplasty includes an acetabular shell to be attached to an acetabulum. The acetabular shell includes an inner surface defining a shell cavity and having a tapered shell section. The acetabular shell includes a tool interlocking structure that mates with a shell insertion tool to inhibit rotation relative to the shell insertion tool. The acetabular shell includes a snap-fit receiver. An acetabular liner is sized and shaped to be disposed in the shell cavity of the acetabular shell. The acetabular liner including an outer surface having a tapered liner section corresponding to the taper of the tapered shell section and engages the tapered shell section to inhibit movement of the acetabular liner relative to the acetabular shell. The acetabular liner includes a snap-fit retainer received by the snap-fit receiver of the acetabular shell to form a snap-fit connection between the acetabular liner and the acetabular shell.

Abstract: In an example of the method, a functionalized coating layer is applied in depressions of a patterned flow cell substrate. The depressions are separated by interstitial regions. A primer is grafted to the functionalized coating layer to form a grafted functionalized coating layer in the depressions. A hydrogel is applied on at least the grafted functionalized coating layer.
