Abstract: A narrow channel created by one or more channel walls. The channel is engineered with narrow dimensions so as to carry out its function of supporting small bags filled with waste. The channel may be formed as a single body, attached to another body, or formed or incorporated into another body or device, such as, but not limited to, animal leashes, retractable animal leashes, pet waste bag dispensers, pet harnesses, and pooper scoopers. Bags containing animal waste may be inserted into the channel. The bags may be supported by the channel. Additional small bodies including but not limited to rings or cord loops may be inserted into and supported by the channel.

Abstract: Scoops for picking up pet waste including a first arm pivotally connected to a second arm at a pivot end, wherein the first arm and the second arm define a collection region distal the pivot end, the second arm being configured to pivot relative to the first arm between an open position and a closed position, the collection region being configured to encompass the pet waste in the collection region when the second arm is in the open position. In certain examples, the scoop includes a coupler configured to facilitate forming a knot in the pet waste bag. In some examples, the scoop includes a container configured to store pet waste bags. In some examples, the scoop includes a latch configured to selectively restrict the second arm pivoting relative to the first arm.

Abstract: Compositions, methods and systems that inactivate proviral HIV-1 by genome editing to excise viral sequences, thereby inactivating production of nascent virus. In some embodiments, proviral DNA is excised by targeting the LTR region of integrated viral DNA using a CRISPR/Cas9 lentiviral construct. Use of the lentiviral construct advantageously permits transduction of both dividing and non-dividing target cells.
