Abstract: A stair system that is associated with a cargo platform of a commercial vehicle for transporting goods is disclosed. The stair system is integral with the vehicle and/or the cargo platform and provides a user/operator with easy and safe access to the cargo platform without occupying the storage space provided by the cargo platform. The stair system can be arranged in a deployed configuration when in use and in a stowed configuration that is road-ready and does not prevent the vehicle from being operated on paved roads.

Abstract: A stair system for providing access to a cargo platform of a commercial vehicle is disclosed. The stair system is movable between a deployed configuration and a stowed configuration. The stair system comprises a mounting plate, a stair assembly, and a linkage assembly. The mounting plate is configured to be attached to the cargo platform of the commercial vehicle. The stair assembly includes a top platform that is slidably received within the mounting plate and a plurality of step platforms that is pivotally attached to the top platform. The linkage assembly comprising at least one slotted link that includes a slot and at least one first link that is slidable relative to the slot. When in the stowed configuration, the stair system is configured to be positioned beneath the cargo platform. When in the deployed configuration, the stair system is configured to extend outwardly from the cargo platform.

Abstract: A method for treating abnormal blood vessel growth and proliferation is disclosed. Members of the hypocrellin class of compounds such as hypocrellin A, hypocrellin B, and/or amino-substituted derivatives of hypocrellin B are administered and photoactivated with photodynamic therapy. The method may be used, for example, to treat ocular blood vessel proliferation as occurs with macular degeneration.
