Abstract: An aqueous formulation includes a PEDF-derived short peptide (PDSP) having the sequence of one of SEQ ID NO: 1, 2, 3, 5, 6, 8 or 9; boric acid at a concentration of 0.01 mM-923 mM; and a non-ionic tonicity agent. The pH value is around 5.5-8.4. The non-ionic tonicity agent is glycerin, sucrose, mannitol, or sorbitol. A concentration of the PDSP is 0.01%-1% w/v.

Abstract: An aqueous formulation includes a PEDF-derived short peptide (PDSP) having the sequence of one of SEQ ID NO: 1, 2, 3, 5, 6, 8, or 9; histidine having a concentration of 1 mM-100 mM; and an antioxidant and optionally a non-ionic tonicity agent. The pH value is around 5-9. The antioxidant is nicotinamide, which is at a concentration of 50 mM-1000 mM. The non-ionic tonicity agent is sorbitol, which is at a concentration of 0 mM-500 mM. A concentration of the PDSP is 0.01%-1% w/v.

Abstract: A magnetic connection cable is composed of a main body and two magnets mounted to the main body. The main body includes a first end portion and a second end portion opposite to the first end. The two magnets are mounted to the first and second end potions separately. The first and second end portions of the magnetic connection cable can magnetically attract each other for convenient storage and effective reduction of the size of the connection cable in storage to overcome the drawback of the prior art. Besides, the connection cable of the present invention with the magnetic attraction can function as a general magnetic fastener for fastening an object, like paper, to the surface of a magnetically attractable object.
