Abstract: Provided herein are antibodies or antigen-binding fragments thereof, e.g., monoclonal antibodies or antigen binding fragments thereof, that specifically bind to ENTPD2 (e.g., human ENTPD2 protein), and methods of using these antibodies or antigen-binding fragments. The present invention also relates to combination therapies comprising an anti-human ENTPD2 antibody or antigen binding fragment and at least one additional therapeutic agent, and methods of using these combination therapies.

Abstract: A golf mat has a down-blow impact mat removably placed in a cutout formed in a base. The upper surface of the down-blow impact mat has a hitting section that slopes down gradually from the high point to a target point. The down-blow impact mat also has a lower portion having a sloping section and a flat section. The golf mat disclosed helps to improve the golfer's takeaway swing and the downswing so the golfer may practice his or her swing, including but not limited to, better mastering the elusive two-plane golf swing, with the guidance of the sloped hitting surface.

Abstract: Lineup glasses has a left lens connected to a right lens. One or both of the left lens and the right lens has a horizontal line and one or both of the left lens and the right lens may also have a vertical line that is perpendicular to the horizontal line. In addition, the horizontal line may have a plurality of horizontal spacing points and the vertical line may have a plurality of vertical spacing points. The horizontal line and the vertical line on a lens create a virtual target line and a virtual vertical line, respectively, visible and could be superimposed over the golf ball and the ground so that the golfer could better align his stance, see a straight line between the ball and the target represented by the virtual target line, and to better estimate the distance between the ball and the target.

Abstract: A golf mat has a high-density polyurethane viscoelastic foam removably placed in a cutout formed in a base. A hitting section is attached to an upper surface of the foam so that impacts of golf swing hitting the mat is absorbed by the foam. The foam may be placed in a protective bag to protect the foam from chipping and fraying. The hitting area is made with nylon having thermochromic pigments so that the pigments change color temporarily due to increased temperature from friction caused by impact and swipe of a golf clubhead on the hitting section when the golf clubhead hits the hitting section. The mat has a standing section with vertical lines and horizontal lines for the alignment of the golfer's feet. Moreover, the mat has a first set and a second set of on-the-mat-swing-path lines to compare the direction of temporary heat signature left by a divot.
